Description

Chip cutting device with upper cover body

Technical Field

The invention relates to a chip cutting device with an upper cover body.

Background

Various cutting devices are available on the market in order to be able to perform operations such as cutting, tail grooving, chip milling and the like on a workpiece. For example, a material end face machining center disclosed in chinese patent application with patent No. CN202010613710.7 entitled "a material end face machining device and a material end face machining center" includes a moving device and a machining tool assembly, and an output end of the moving device is connected to the machining tool assembly for driving the machining tool assembly to move. The machining tool assembly includes a tool driver and a tool. The material loading device is characterized by further comprising a material loading frame and a material clamp, wherein the material clamp is mounted on the material loading frame and used for pressing materials at the material loading frame. The device is generally used for processing the end face of a long strip workpiece, so that the long strip workpiece needs to be placed on the feeding frame before processing, one end of the long strip workpiece extends into the material clamp and is pressed by the material clamp, and the rest part of the long strip workpiece is still supported by the feeding frame. The material end face machining center is of a full-open type, scraps formed in the machining process can splash onto the bodies of workers standing in front and even fly into human eyes, and the scraps are scattered around and are not very beneficial to cleaning and maintaining clean working environment. The more likely safety hazard is that the hand is very likely to touch the knife and be cut.

Disclosure of Invention

In view of the above technical problems, it is easy to think of adding a protective cover for covering the machining tool assembly, but if the machined object is a long workpiece, the protective cover needs to have a very large accommodating space, or a window for allowing the long workpiece to pass through needs to be arranged on the protective cover, but the window becomes a gap through which scraps splash, and also becomes a passage through which a human hand extends into the protective cover, so that the scrap blocking and protection effects of the protective cover are greatly reduced.

In view of the above, one of the objectives of the present invention is to provide a chip cutting apparatus with an upper cover, which is suitable for chip cutting of a long workpiece and has good chip blocking and protecting effects, and the chip cutting apparatus includes an upper cover, characterized in that the upper cover includes a front side cover wall, a clamping device for clamping the workpiece and a chip cutting assembly for chip cutting of the workpiece clamped on the clamping device are disposed behind the front side cover wall, and the clamping device includes a pair of clamping arms capable of being tightened and opened; a feeding inlet is arranged on the front side cover wall and faces the pair of clamping arms, so that a channel for conveying a workpiece to the pair of clamping arms can be formed by the feeding inlet, and the cutting equipment further comprises a movable protection plate; when the centre gripping arm tightens up, the guard plate removes and shelters from the pay-off entry, but if the centre gripping arm centre gripping has the work piece, the guard plate lets the pay-off entry remains the space that lets the work piece pass through.

The front side cover wall is provided with a clamping device for clamping a workpiece and a chip processing component for performing chip processing on the workpiece clamped on the clamping device at the rear part, the position relation among the front side cover wall, the clamping device and the chip processing component is defined, when a user stands in front of the front side cover wall, the front side cover wall is blocked among the clamping device, the chip processing component and the user, and the front side cover wall can block waste chips splashed from the chip processing component.

Wherein the chip-machining component is a mechanical assembly comprising a tool mount for mounting a tool required for cutting. The cutter can be used for processing a workpiece clamped on the clamping device in a segmented cutting mode, tail end grooving, chip milling and the like. Different types of cutters are selected according to different machining types, for example, a cutting blade is adopted in the process of segmentation cutting, and a milling cutter is adopted in the process of milling chips. As for the material for manufacturing the cutter, various materials are available, such as a metal cutter, a laser cutter, and a ceramic cutter.

Wherein the feed inlet is opposed to the pair of gripper arms to define a positional relationship between the feed inlet and the pair of gripper arms, and the feed inlet and the pair of gripper arms are arranged to face each other so that the workpiece can pass through the feed inlet into the gripper space between the pair of gripper arms.

The protection plate is a movable component which controls the size of a feeding channel formed by the feeding inlet in a mode of shielding the feeding inlet. When the clamping arms are tightened, the protection plates move and shield the feeding inlet so as to narrow the feeding channel, external objects such as human hands cannot easily penetrate through the residual space of the feeding inlet to extend to the rear of the front side cover wall, and waste scraps cannot easily splash to the front of the front side cover wall through the residual space of the feeding inlet. However, if the workpiece is clamped by the clamping arm, the protective plate does not completely shield the feeding inlet, but a space for the workpiece to pass through is reserved in the feeding inlet, so that the hand and dust can be blocked from passing through the feeding inlet, and the rear part of the workpiece is not prevented from staying in front of the front side cover wall. However, if the clamping arm does not clamp the workpiece at this time, the protection plate may completely or incompletely shield the feeding inlet, which depends on the configuration of design parameters such as a control program, a driving mode, or a maximum moving stroke of the protection plate. When the clamping arms are opened, the protection plates move in the direction far away from the feeding inlet, the shielding area is reduced, the feeding channel formed by the feeding inlet is widened, and convenience is provided for conveying workpieces to the clamping arms again in the next working period.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that:

first, since the feed inlet is provided in the front side cover wall, the feed inlet faces the pair of gripper arms, so that the workpiece can enter the gripper space between the pair of gripper arms through the feed inlet, if the workpiece is elongated, the rear portion of the workpiece can stay in front of the front side cover wall without passing through the feed inlet to enter the rear of the front side cover wall. The arrangement of the upper cover body does not influence the chip cutting processing of the chip cutting equipment on the long-strip-shaped workpiece.

Secondly, due to the arrangement of the protection plate with the moving characteristics, when the clamping arms are tightened, the protection plate moves and shields the feeding inlet, but if the clamping arms clamp a workpiece, the protection plate allows the feeding inlet to reserve a space for the workpiece to pass through, so that the protection plate can block hands and dust from passing through the feeding inlet, and does not prevent the rear part of the workpiece from staying in front of the front side cover wall.

The driving structure of the protection plate is various, for example, a protection plate driver specially used for driving the protection plate to move and a sensor used for detecting whether the pair of clamping arms are tightened or not are arranged, and when the sensor detects that the pair of clamping arms are tightened, the protection plate driver drives the protection plate to move and shields the feeding inlet. In order to simplify the driving structure, the invention further adopts the following technical scheme: the clamping device further comprises a clamping arm automatic driver, at least one of the clamping arms is a movable clamping arm, the clamping arm automatic driver is in transmission connection with the movable clamping arm and can drive the movable clamping arm to move relative to the other clamping arm, and the clamping arm automatic driver is in transmission connection with the protection plate. The automatic driver of the clamping arm can be a motor, an air cylinder, an oil cylinder and other power devices. In addition, at least one of the pair of clamping arms is a movable clamping arm, and the following two possibilities exist in specific application: both of the pair of gripper arms may be movable, or only one of the gripper arms may be movable, the movable gripper arm being named movable gripper arm. And secondly, the clamping arm automatic driver is also in transmission connection with the protection plate, so that the protection plate can move under the driving of the clamping arm automatic driver, and in one application, the output end of the clamping arm automatic driver is directly connected to the protection plate, or the output end of the clamping arm automatic driver is firstly connected to an intermediate transition piece, and then the protection plate is connected to the intermediate transition piece. According to the technical scheme, the clamping arm automatic driver can drive the movable clamping arm to move and can also drive the protection plate to move, one object has two purposes, and the driving structure of the protection plate can be greatly simplified.

The further technical scheme can also be that the protection plate is connected to the movable clamping arm. Therefore, the movable clamping arms become the mounting base of the protection plate, on one hand, the mounting structure of the protection plate is simplified, on the other hand, the movable clamping arms which move are used for synchronously driving the protection plate to move, and therefore the driving structure of the protection plate is further simplified.

The material clamping device further comprises a driver mounting seat, and the automatic driver of the clamping arm is arranged on the driver mounting seat; the driver mount is disposed at a side of the guard plate and provides a movement guide for the guard plate. Like this, the driver mount pad not only can be for arm lock automatic drive provides the location basis, can also be for the guard plate provides the removal direction, and an object dual-purpose is favorable to simplifying the guide structure of guard plate.

The protection plate comprises a main plate part and a pair of plate flanges which are respectively bent and formed at the left side and the right side of the main plate part, and the left side and the right side of the driver mounting seat are embraced by the pair of plate flanges. Therefore, the structure that the left side and the right side of the driver mounting seat are embraced by the pair of plate flanging is used for regulating the left-right swing amplitude of the protection plate, and the movement stability of the protection plate is improved. And the manufacturing process of the plate flanging is very simple, such as stamping, bending and forming. Above-mentioned scheme can simplify greatly the guide structure of guard plate.

In order to collect the scraps, the invention further provides the following technical scheme: the upper cover body comprises a rear side cover wall arranged opposite to the front side cover wall, a left side cover wall and a right side cover wall which are arranged between the front side cover wall and the rear side cover wall, and the front side cover wall, the rear side cover wall, the left side cover wall and the right side cover wall are combined to form an annular cover side wall; the cutting and machining device further comprises a supporting bottom frame, wherein the supporting bottom frame comprises an outer frame and a supporting beam erected on the outer frame, the side wall of the cover is erected on the outer frame, and the cutting and machining assembly is arranged on the supporting beam; the bottom end of a waste chip collecting range defined by the waste chip guide surfaces is completely converged into the waste chip collector; the support chassis is provided with a chip passing space, and the vertical projection of at least part of the chip passing space avoids the chip guide surface and directly falls into the waste chip collector.

According to the above technical solution, firstly, since the hood side wall stands on the outer frame, the support beam is erected on the outer frame, the scrap collector is arranged below the support beam, and at least part of the vertical projection of the scrap passing space avoids the scrap guide surface and directly falls into the scrap collector, so that a scrap collecting space is formed above the support beam through the hood side wall, and a scrap collecting space is formed below the support beam through the scrap collector, a large amount of scraps generated and splashed outwards in the working process of the scrap processing assembly are intercepted by the hood side wall and temporarily collected in the hood inner cavity. And one part of the waste scraps gathered in the cover inner cavity directly falls into the waste scrap collector through the scrap passing space, and the other part of the waste scraps falls onto the scrap guide surface and is guided into the waste scrap collector by virtue of the scrap guide surface. In conclusion, according to the technical scheme, the amount of the waste scraps splashed out of the scrap cutting equipment is reduced through the upper cover body, the waste scrap collection rate is improved, the arrangement position relation between the scrap passing space and the scrap guide surface is specially designed, the amount of the waste scraps remained on the scrap guide surface is reduced, and finally the workload of cleaning the waste scraps is reduced. In addition, compared with the material guide plate in the prior art 202010454576.0, the scrap guide surface can adopt a small spoke structure, so that the material consumption is reduced, and the production cost is reduced. Secondly, as the chip guide surface which is obliquely arranged from top to bottom is arranged on the inner side of the outer frame, the bottom end of the waste chip collecting range defined by the chip guide surface is completely converged into the waste chip collector, so that the waste chip collecting range defined by the chip guide surface becomes a transition passage arranged between the chip collecting space and the chip collecting space, and dust is prevented from splashing and falling out of the waste chip collector.

Each of the specific implementation details, structures and methods disclosed below are described in detail as being necessary, and in addition to the specific descriptions pertaining to equivalent or alternative embodiments, the various implementation details disclosed below may be used selectively or combined in one embodiment, even if not directly related or synergistic in functional terms.

As shown in fig. 1, 2 and 3, the upper casing 100 includes a front casing wall 1, a rear casing wall (not shown) disposed opposite to the front casing wall 1, and a left casing wall 11 and a right casing wall 12 disposed between the front casing wall 1 and the rear casing wall, and the front casing wall 1, the rear casing wall, the left casing wall 11 and the right casing wall 12 are combined to form a ring-shaped casing side wall 10. The left side cover wall 11 comprises a left side inward flange 111 extending inwards, and the left side cover wall 11 stands on the outer frame 2 through the left side inward flange 111. The right side cover wall 12 comprises a right side inward flange 121 extending inwards, and the right side cover wall 12 stands on the outer frame 2 through the right side inward flange 121. In other embodiments, the upper housing 100 may include only one housing sidewall of the front housing wall 1, and the arrangement of the rear housing wall, the left housing wall 11, and the right housing wall 12 is omitted.

As shown in fig. 1 to 4, the supporting chassis 200 includes an outer frame 2 and a pair of supporting beams 21 arranged at intervals and erected on the outer frame 2. The chip cutting assembly 300 is slidably disposed on a pair of the support beams 21, and the chip cutting assembly 300 is used for chip cutting a workpiece clamped on the clamping device 500. Specifically, the cutting assembly 300 includes a slide 3 capable of sliding on the support beam 21, a support column 31 provided on the slide 3, and a tool mount 32 provided on the support column 31. The tool mount 32 is used for mounting a tool 33 for chip machining a workpiece. A chip-passing hole (not shown) is provided in the slide 3. In this way, the dust falls into the waste collector 400 through the dust passing holes, which is advantageous for reducing the dust accumulated on the sliding base 3. The chip removing assembly 300 is arranged behind the front housing wall 1 and in the housing interior, so that the chip removing assembly 300 is surrounded by the housing side wall 10, and chips generated during operation can be intercepted by the housing side wall 10, thereby reducing the scattering of the chips out of the chip removing device. The hood interior substantially limits the splash-able range of the debris. In addition, the hood side wall 10 stands on the outer frame 2, and the support beam 21 is erected on the outer frame 2, so that the upper space of the outer frame 2 or the upper space of the support beam 21 also forms a dust collecting space.

A pair of intermediate beams 22 arranged at intervals and a chip blocking plate 23 covering the intermediate beams 22 are further arranged on the outer frame 2, and the support beams 21 are transversely erected on the intermediate beams 22 and exposed out of the chip blocking plate 23. The support chassis 200 further includes support legs 25, and the support legs 25 are used to erect the outer frame 2, the support beams 21, and the intermediate beams 22, thereby forming a space for placing the scrap collector 400 thereunder. The chip blocking plate 23 comprises a plate main body 232 and a sloping plate part formed by bending the side edge of the plate main body 232, wherein the upper surface 231 of the sloping plate part forms part of a chip guide surface, namely part of a guide surface is formed on the chip blocking plate 23. The chip blocking plate 23 blocks not only the middle beam 22 but also the space between the middle beam 22 and the middle beam, so that the number of the waste chip collectors 400 can be reduced by omitting the arrangement of the waste chip collectors 400 below the middle beam 22 and the space between the middle beam and the middle beam, and dust can be intensively placed on one or a small number of waste chip collectors 400, in the embodiment, only two waste chip collectors 400 are needed. This can reduce the amount of work for carrying and cleaning the scrap collector 400. An inclined plate 26 is further provided on the inner side wall of the outer frame 2, and a part of the chip guide surface is formed by an upper surface 261 of the inclined plate 26. The upper surface 231 of the ramp portion and the upper surface 261 of the ramp plate 26 form a chip guide surface 28 (for ease of discussion, the chip guide surfaces are collectively designated 28) that are disposed at a face-to-face spacing inside the housing frame 2. Of course, in other embodiments, the chip guide surface 28 may be annularly disposed inside the outer frame 2, that is, in the present embodiment, two chip guide surfaces may be disposed at front and rear positions between the upper surface 231 of the inclined plate portion and the upper surface 261 of the inclined plate 26; in addition, the chip guide surface 28 may be formed by directly using the inner surface of the outer frame 2. The bottom end of the waste collection range defined by the waste guide surface 28 is totally converged into the waste collector 400, the vertical projection defining the bottom end of the waste collection range defined by the waste guide surface 28 is totally fallen into the waste collector 400, and the waste collection space is similar to a funnel, not only can collect dust in a widening opening manner, but also can intensively throw the dust into the waste collector 400 in a narrowing opening manner.

The dust-passing space 27 is formed in a part of the space between the pair of support beams 21 and between the support beams 21 and the outer frame 2 (of course, in other embodiments, the dust-passing space 27 may be formed in the entire space). The chip space 27 communicates between the hood chamber above the support beam 21 and the chamber of the chip collector 400 below the support beam 21. When viewed from top to bottom, a vertical projection of a part of the chip passing space falls on the chip guide surface 28; while the vertical projection of the other part of the chip space falls off the chip guide surface 28 and directly into the chip collector 400, i.e. the other part of the chip space is not projected onto the chip guide surface 28 but directly projected into the chip collector 400 (of course, in other embodiments, the whole chip space is not projected onto the chip guide surface 28 but directly projected into the chip collector 400). The part of the dust collected in the cover inner cavity and falling downwards can directly fall into the waste collector 400 through the other part of the dust passing space without the guidance of the dust guide surface 28, so that the amount of the dust remained on the dust guide surface 28 is reduced.

As shown in fig. 3 and 5, the scrap collector 400 is a container for collecting the scrap, and is disposed below the support beam 21 such that a scrap collecting space is formed below the support beam 21 by the scrap collector 400, and the scrap collected in the hood inner chamber by being intercepted by the hood side wall 10 is collected in the scrap collector 400. Scrap collector 400 is including preceding collector front side wall 4 and the collector back side wall 4a of preceding, back branch position, and left and right branch position's collector left side wall 42 and collector right side wall 43 to and collector diapire 44, preceding collector front side wall 4 bends and forms preceding handle portion 41, collector back side wall 4a bends and forms back handle portion 41a (in other embodiments, can be one of them lateral wall in preceding collector front side wall 4 and the collector back side wall 4a bend and form handle portion can) like this, integrative being formed on preceding collector front side wall 4 has preceding handle portion 41, integrative being formed on collector back side wall 4a has back handle portion 41a, simple structure. And the scrap collector 400 can be conveniently pulled out for cleaning by the front and rear grip portions 41 and 41 a. Further, a left corner 421 greater than 90 ° is formed between the collector left side wall 42 and the collector bottom wall 44; the right side corner 431 of more than 90 ° is formed between the right side wall 43 of the collector and the bottom wall 44 of the collector. Wherein the left collector side wall 42 and the right collector side wall 43 are arranged obliquely from outside to inside. This facilitates cleaning of dust and debris accumulated on the left and right corner portions 421 and 431. In addition, the scrap collector 400 further comprises a left outer wall 45 arranged outside the collector left side wall 42, a left connecting piece 47 is connected between the collector left side wall 42 and the left outer wall 45, and a left pulley 49 is arranged on the left connecting piece 47; the scrap collector 400 further comprises a right outer wall 46 arranged on the outer side of the right side wall 43 of the collector, a right connecting piece 48 is connected between the right side wall 43 of the collector and the right outer wall 46, and a right pulley 49a is arranged on the right connecting piece 48. Thus, the left and right connecting members 47, 48 can be provided to facilitate the installation of the left and right pulleys 49, 49 a. The left and right connectors 47, 48 are higher than the collector bottom wall 44. That is, the collector bottom wall 44 is concavely disposed between the left and right connecting members 47 and 48, so that the present invention not only provides an adequate installation space in the height direction for the left and right pulleys 49 and 49a, but also enlarges the volume of the scrap collector 400, compared to the case where the left and right connecting members 47 and 48 and the collector bottom wall 44 are disposed flush with each other.

According to the technical scheme, compared with the prior art, the invention has the beneficial technical effects that: firstly, since the hood side wall 10 stands on the outer frame 2, the supporting beam 21 is erected on the outer frame 2, the scrap collector 400 is arranged below the supporting beam 21, and at least a part of the vertical projection of the scrap space 27 avoids the scrap guiding surface 28 and falls directly into the scrap collector 400, so that a scrap collecting space is formed above the supporting beam 21 by the hood side wall 10, and a scrap collecting space is formed below the supporting beam 21 by the scrap collector 400, and a large amount of scrap generated and splashed outwards during the operation of the scrap machining assembly 300 is intercepted by the hood side wall 10 and temporarily collected in the hood inner cavity. The waste chips collected in the housing chamber partly fall through the chip-passing space 27 directly into the waste chip collector 400 and partly onto the chip-guiding surface 28 and are guided into the waste chip collector 400 by means of the chip-guiding surface 28. In summary, according to the technical solution of the present invention, not only is the amount of the scraps splashed out of the cutting equipment reduced by the upper cover 100, and the collection rate of the scraps is improved, but also the layout position relationship between the scrap passing space 27 and the scrap guide surface 28 is specially designed, so that the amount of the scraps remaining on the scrap guide surface 28 is reduced, and finally, the workload of cleaning the scraps is reduced. In addition, compared with the material guiding plate in the prior art 202010454576.0, the scrap guiding surface 28 can adopt a small-surface spoke structure, thereby reducing the material consumption and the production cost. Secondly, since the scrap guide surface 28 is disposed on the inner side of the housing frame 2 and is inclined from top to bottom, the bottom end of the scrap collecting range defined by the scrap guide surface 28 is entirely gathered in the scrap collector 400, so that the scrap collecting range defined by the scrap guide surface 28 becomes a transition passage disposed between the scrap collecting space and the scrap collecting space, and dust is prevented from splashing and falling out of the scrap collector 400.

As shown in fig. 1 and 6, a material clamping support seat 24 is provided on the outer frame 2, and the material clamping device 500 is provided on the material clamping support seat 24, is accommodated in the cover inner cavity, and is located behind the front side cover wall 1.

In addition, the material clamping device 500 and the chip cutting assembly 300 are both located behind the front shroud wall 1. When a user stands in front of the front side cover wall 1, the front side cover wall 1 is blocked between the material clamping device 500, the chip processing component 300 and the user, and the front side cover wall 1 can block waste chips splashed from the chip processing component 300 position like a screen.

The material clamping device 500 includes a pair of clamping arms 5 capable of being tightened and opened, that is, an upper clamping arm 51 and a lower clamping arm 52 which are separately arranged up and down, wherein the upper clamping arm 51 is a movable clamping arm which is movable, and the lower clamping arm 52 is a stationary fixed clamping arm (of course, in other embodiments, a pair of the clamping arms 5 may also be separately arranged left and right, or both clamping arms are movable clamping arms). The material clamping device 500 further comprises a driver mounting seat 53 and a clamping arm automatic driver 55. The driver mount 53 is located above the upper clamp arm 51. The clamping arm automatic driver 55 is disposed on the driver mounting seat 53, and an output shaft of the clamping arm automatic driver 55 passes through the driver mounting seat 53 and is in transmission connection with the upper clamping arm 51 (of course, in other embodiments, the driver mounting seat 53 may also be located on a side edge or other position of the upper clamping arm 51, as long as the clamping arm automatic driver 55 can be provided with mounting positioning). A guide post 54 is provided between the driver mount 53, the upper clamp arm 51, and the lower clamp arm 52. The clamping arm automatic driver 55 can drive the upper clamping arm 51 to move relative to the lower clamping arm 52 under the guidance of the guide column 54.

The feed inlet 13 faces the pair of gripper arms 5, and the feed inlet 13 is arranged to face the pair of gripper arms 5, so that a workpiece can enter the gripping space between the pair of gripper arms 5 through the feed inlet 13, and if the workpiece is elongated, the rear portion of the workpiece can stay in front of the front shroud wall 1 without passing through the feed inlet 13 to the rear of the front shroud wall 1. The arrangement of the upper cover 100 does not influence the chip processing of the long workpiece by the chip processing equipment.

The clamping arm automatic driver 55 is also in transmission connection with the protection plate 6. In particular, the protection plate 6 is connected to the movable holding arm, i.e. the upper holding arm 51. In this way, the movable clamping arm becomes the mounting base of the protection plate 6, on one hand, the mounting structure of the protection plate 6 is simplified, and on the other hand, the movable clamping arm which moves is used for synchronously driving the protection plate 6 to move, so that the driving structure of the protection plate 6 is further simplified. According to the technical scheme, the clamping arm automatic driver 55 can drive the movable clamping arm to move and can also drive the protection plate 6 to move, so that the driving structure can be greatly simplified due to the two purposes of one object. In other embodiments, it is also possible that the output of the gripper arm automatic driver 55 is connected directly to the protection plate 6; or the output end of the clamping arm automatic driver 55 is connected to the intermediate transition piece first, and then the protection plate 6 is connected to the intermediate transition piece; or a protection plate driver specially used for driving the protection plate 6 to move and a sensor used for detecting whether the pair of clamping arms 5 are tightened are arranged, and when the sensor detects that the pair of clamping arms 5 are tightened, the protection plate driver drives the protection plate 6 to move and shields the feeding inlet 13. The drive structure of guard plate 6 is diversified, does not list in one row.

The driver mount 53 is disposed at a side of the shielding plate 6 and provides a moving guide for the shielding plate 6. Specifically, the protection plate 6 includes a main plate portion 61 and a pair of plate flanges 62 (including a left plate flange 62a and a right plate flange 62 b) respectively bent and formed at left and right sides of the main plate portion 61, and the pair of plate flanges 62 embraces left and right sides of the driver mounting seat 53. In this way, the structure that the pair of plate flanges 62 embrace the left and right sides of the driver mounting seat 53 regulates the horizontal swing amplitude of the protection plate 6, and improves the movement stability of the protection plate 6. The manufacturing process of the plate flange 62 is also very simple, for example, press bending. In this way, the driver mounting seat 53 not only can provide a positioning basis for the automatic clamping arm driver 55, but also can provide movement guidance for the protection plate 6, so that the two purposes are achieved, and the guide structure of the protection plate 6 can be simplified.

The protection plate 6 is a movable member for controlling the size of a feeding channel formed by the feeding inlet 13 in a mode of shielding the feeding inlet 13. When the holding arm 5 is tightened, the protection plate 6 moves and shields the feeding inlet 13 to narrow the feeding passage, and foreign objects such as human hands cannot easily penetrate through the remaining space of the feeding inlet 13 to reach the rear of the front side cover wall 1, and waste chips cannot easily splash through the remaining space of the feeding inlet 13 to the front of the front side cover wall 1. However, if the workpiece is clamped by the clamping arm 5, the protective plate 6 does not completely block the feeding inlet 13, but allows the feeding inlet 13 to have a space for the workpiece to pass through, so that the hand and dust can be blocked from passing through the feeding inlet 13 without preventing the rear part of the workpiece from staying in front of the front side cover wall 1. However, if the clamping arm does not clamp the workpiece at this time, the shielding plate 6 may completely or incompletely shield the feeding inlet 13, depending on the configuration of design parameters such as a control program, a driving manner, or a maximum moving stroke of the shielding plate 6. When the clamping arms 5 are opened, the protection plate 6 moves in the direction away from the feeding inlet 13, the shielding area is reduced, the feeding channel formed by the feeding inlet 13 is widened, and convenience is provided for conveying workpieces to the clamping arms 5 again in the next working period.
