Referring to fig. 1-5, the present embodiment takes a holding frame (not shown) of a mobile phone as an example, and the fixture is specifically described as follows:
referring to fig. 1-3, the jig includes a jig body 1, a first clamping portion 2, a second clamping portion 3, a driving portion 4 and an elastic portion 5. The first clamping part 2 is fixedly connected to the jig body 1. The second clamping part 3 is movably connected to the jig body 1 and can move towards or away from the first clamping part 2, so that the second clamping part has a first working position which is matched with the first clamping part 2 to fix the mobile phone frame, and a second working position which is suitable for placing or taking the mobile phone frame into or out of the jig. The driving portion 4 is used for applying an external force to the second clamping portion 3 to make the second clamping portion 3 be in the second working position. The elastic part 5 is connected or abutted with the second clamping part 3; the elastic portion 5 is elastically deformable when the second clamping portion 3 is in the second operating position, and is elastically deformable after the external force of the driving portion 4 is removed to restore and maintain the second clamping portion 3 in the first operating position.
Because the elastic part 5 can continuously support against the mobile phone frame, so that the mobile phone frame is fixed between the first clamping part 2 and the second clamping part 3, namely, when the jig is in a working state for clamping the mobile phone frame, the driving part 4 serving as a power source does not need to be kept or even does not need to apply power (external force) to the second clamping part 3, and only needs to work for a short time in the process of putting the mobile phone frame into or taking the mobile phone frame out of the jig, thereby greatly shortening the working time of the driving part 4, reducing the energy consumption and prolonging the service life of the driving part 4.
Meanwhile, in the automatic production, when the jig performs the clamping action, the displacement stroke of the executing component (such as the second clamping part 3) depends on the parameters of the linear displacement or the angular displacement of the driving part 4, and the like, which are determined by the preset program. If the size of the workpiece has a positive deviation from the standard size, the executing component will excessively press against the mobile phone frame, causing damage to the jig itself or the mobile phone frame, and if the size of the workpiece has a negative deviation from the standard size, it is difficult to ensure that the jig can reliably clamp the workpiece, which affects the processing quality and result. However, in the present embodiment, since the clamping force of the second clamping portion 3 as the actuating member is derived from the elastic portion 5 which can be elastically deformed, the jig can allow a certain dimensional deviation of the workpiece, and does not form a rigid pressing force on the workpiece.
In this embodiment, the fixture body 1 may be made of metal material such as stainless steel, so that it has sufficient structural strength and is not easy to deform. To reduce the weight, volume and cost of the jig, the driving part 4 is preferably, but not limited to, a cylinder, which is not limited to a single-acting cylinder or a double-acting cylinder.
In this embodiment, the first clamping portion 2 and the second clamping portion 3 may be disposed opposite to each other, may be a limiting protrusion structure integrally formed on the jig body 1, or may be a detachable component independent from the jig body 1, and is convenient to be made of a material having a hardness different from that of the jig body 1, suitable for clamping different mobile phone frames, and simultaneously suitable for replacing and adjusting the installation position.
The number of the first clamping parts 2 and the second clamping parts 3 arranged on the jig is not limited, so that reliable clamping structures such as multi-point support, point-to-face support, face-to-face support and the like can be formed in a matching manner.
For example, in the present embodiment, the second clamping portion 3 includes a first clamping block 31 and a first push rod 32. The first clamping block 31 is movably connected to the first side 11 of the fixture body 1. The first push rod 32 is connected to the first clamping block 31 and can apply an external force to the first clamping block 31 to drive the first clamping block 31 to move along the first direction.
It can be understood that the first direction should extend towards the first side 11, so that the first clamping block 31 can move towards the first side 11, i.e. can move towards the mobile phone frame carried on the fixture body 1, and cooperate with the first clamping portion 2 to clamp the mobile phone frame.
In a manner adapted to the structure of the second clamping portion 3, the elastic portion 5 may specifically include a first elastic element 51, and the first elastic element 51 is connected to or abutted against the first push rod 32 and can contract or expand along the first direction. That is, when the driving portion 4 applies an external force to the first clamping block 31 by means of the first push rod 32, the first push rod 32 pushes the first elastic element 51, so that the first elastic element 51 contracts to store energy, and after the driving portion 4 is reset, the first elastic element 51 recovers to deform and stretches to press against the first push rod 32, so that the first push rod 32 drives the first clamping block 31 to clamp the mobile phone frame.
Specifically, the first elastic element 51 may be a spring, which is axially disposed in parallel to the first direction, and has one end fixedly connected to the first push rod 32 or movably connected to the first push rod in an inserting manner or a sleeving manner, and the other end fixedly connected to the jig body 1 or movably connected to the jig body in an inserting manner or a sleeving manner.
For further reliable clamping of the handset frame, the second clamping portion 3 may further comprise a second clamping block 33 and a second pushing bar 34. The second clamping block 33 is movably connected to the second side 12 of the fixture body 1, and the second side 12 intersects with the first side 11. The second push rod 34 is connected to the second clamping block 33 and is in transmission connection with the first push rod 32, when the first push rod 32 moves towards the first direction, the second push rod 34 can be driven by the first push rod 32 to drive the second clamping block 33 to move along the second direction, and the second direction is intersected with the first direction.
That is, the first clamping block 31 and the second clamping block 33 are located at different positions on the jig body around the position for the mobile phone frame, so as to clamp the mobile phone frame in a multipoint fit manner. It can be understood that, in the present embodiment, the first clamping portion 2 should be disposed on the fixture body 1 opposite to the first side 11 and the second side 12, so as to cooperate with the first clamping block 31 and the second clamping block 33 to clamp the phone frame together.
Suitably, the elastic portion 5 further includes a second elastic element 52, and the second elastic element 52 is connected to or abutted against the second push rod 34 and can contract or expand along the second direction. That is, when the driving portion 4 applies an external force to the first clamping block 31 by means of the first push rod 32, the second push rod 34 is pushed by the first push rod 32 and drives the second clamping block 33 to move, and meanwhile, the second elastic element 52 is pushed and pressed, so that the second elastic element 52 contracts and stores energy, and after the driving portion 4 is reset, the second elastic element 52 recovers to deform and stretches to press the second push rod 34, so that the second push rod 34 drives the second clamping block 33 to clamp the mobile phone frame.
Specifically, the second elastic element 52 may also be a spring, which is axially disposed in parallel to the second direction, and one end of the spring is fixedly connected to the second push rod 34 or movably connected thereto in a plugging or sleeving manner, and the other end of the spring is fixedly connected to the jig body 1 or movably connected thereto in a plugging or sleeving manner.
The number of the first clamping blocks 31 and the second clamping blocks 33 can be one, two or more, that is, one, two or more first clamping blocks 31 can be connected to the first push rod 32, and one, two or more first clamping blocks 31 can be connected to the second push rod 34. Meanwhile, the mounting positions of the first clamping block 31 and the second clamping block 33 on the first push rod 32 and the second push rod 34 can be further adjusted by different bolting positions and the like, so as to meet the requirement of stably clamping mobile phone frames with different sizes.
In addition, in other optional embodiments, the jig may further include a third push rod, a third clamping block, and the like, which are in transmission connection with the first push rod 32 to form a linkage structure, so as to further cooperate to clamp the mobile phone frames with different shapes in multiple directions, which is not described herein again.
In the embodiment, in order to enable the first push rod 32 and the second push rod 34 to be in transmission connection and form a linkage structure, the first push rod 32 has a first inclined surface 321 arranged towards the second push rod 34, and the second push rod 34 has a second inclined surface 341 arranged towards the first push rod 32; the first inclined surface 321 and the second inclined surface 341 are attached to each other and can slide relatively, so that when the first push rod 32 moves along the first direction, the second push rod 34 moves along the second direction synchronously under the pushing of the first push rod 32.
When the first push rod 32 and the second push rod 34 are located at the positions shown in fig. 2, the second clamping portion 3 is located at the first working position, and when the first push rod 32 and the second push rod 34 are located at the positions shown in fig. 3, the second clamping portion 3 is located at the second working position, that is, when the second clamping portion 3 is switched from the first working position to the second working position, the first push rod 32 and the second push rod 34 respectively drive the first clamping block 31 and the second clamping block 33 to move towards the outer sides of the first side 11 and the second side 12 of the jig body 1, so as to release the mobile phone frame.
To accomplish the above-mentioned motion switching, the first inclined surface 321 and the second inclined surface 341 may be defined by inclined end surfaces of the first wedge part and the second wedge part formed on opposite sides of the first push rod 32 and the second rod, respectively, and planes of the first inclined surface 321 and the second inclined surface 341 should intersect the first direction and the second direction, respectively. Meanwhile, the first inclined surface 321 should be arranged in the direction shown in fig. 2 and 3, that is, the distal end (tip) of the first wedge-shaped component facing away from the first push rod 32 is arranged at the side facing the motion origin thereof (i.e., the side close to the driving part 4, i.e., the upper side in fig. 2 and 3), so that when the first push rod 32 moves towards the motion end thereof, the first wedge-shaped component can push away the second wedge-shaped component adapted to be in sliding fit therewith (i.e., the right side in fig. 2 and 3).
It will be appreciated that the opposite movement effect can be obtained if the first and second inclined surfaces 321, 341 of the first and second wedge members are oppositely arranged.
In order to integrate all parts of the second clamping part 3 into the jig body 1, the first side 11 and the second side 12 of the jig body 1 are both provided with through holes 13, and the first clamping block 31 and the second clamping block 33 are both movably arranged in the through holes 13; the bottom of the jig body 1 is concavely provided with a containing groove 14 communicated with the through hole 13, and the first push rod 32 and the second push rod 34 are both slidably contained in the containing groove 14.
Preferably, the slot 14 includes a first slot 141 and a second slot 142 that are connected to each other, the first slot 141 and the second slot 142 respectively accommodate the first push rod 32 and the second push rod 34 therein, the first slot 141 has a first guiding structure that limits the first push rod 32 to move along a first direction, and the second slot 142 has a second guiding structure that limits the second push rod 34 to move along a second direction.
Specifically, the first guiding structure may be a portion of the cavity wall of the first slot cavity 141 and the first push rod 32 extending parallel to the first direction, and the portion of the cavity wall is in clearance fit with the portion of the first push rod 32, so that the first push rod 32 can only slide along the first direction. The second guiding structure can also be a portion of the wall of the second slot cavity 142 that extends parallel to the second direction with the second push rod 34, the portion of the wall of the cavity engaging with the portion of the second rod to allow the second push rod 34 to slide only in the second direction.
In addition, the bottom of the jig may be provided with a cover plate 15 for covering the accommodating groove 14 to prevent the elastic element, the first push rod 32 and the second push rod 34, etc. from being exposed or separated.
In order to ensure that the mobile phone frame is accurately processed, the mobile phone frame needs to have a determined and unique spatial position after being clamped by the jig. Taking cartesian rectangular coordinates (x, y, z) as an example, when the mobile phone frame is clamped by the first clamping part 2 and the second clamping part 3, x and y coordinate points are defined and determined, and what needs to be determined is the height coordinate z. Thus, in the present embodiment, the height position of the workpiece can be ensured to be determined independently or in combination in the following ways.
First, the jig body 1 can be provided with a carrier plate 6 for holding the mobile phone frame, and the bearing surface of the carrier plate 6 can be matched with the bottom surface of the mobile phone frame, so that the mobile phone frame can be stably placed.
As shown in fig. 1, if the bottom surface of the phone frame for contacting the carrying surface of the fixture is a flat surface, the surface of the carrier 6 may be a flat surface. As shown in fig. 4, if the bottom surface of the mobile phone frame, which is used for contacting the bearing surface of the jig, is an uneven surface, the surface of the carrier plate 6 may be configured to be fittingly embedded with the bottom surface of the mobile phone frame, or a protruding portion of the bottom surface of the mobile phone frame is avoided by forming an avoiding groove, so that the mobile phone frame can have an accurate and determined posture after being placed on the carrier plate 6, and further the spatial position of the mobile phone frame can be determined.
Secondly, in order to make the bottom surface of the mobile phone frame completely fit or lap joint with the bearing surface of the jig or the carrier plate 6 (if any) so as to make the mobile phone frame have an accurate height position, the jig body 1 can be provided with an adsorption part 7 for adsorbing the mobile phone frame. The absorption part 7 can be a vacuum suction nozzle penetrating the fixture body 1 and the support plate 6 (if any), when the fixture performs the action of clamping the mobile phone frame, the vacuum suction nozzle absorbs the bottom surface of the mobile phone frame downwards, so as to ensure that the bottom surface of the mobile phone frame is completely attached or lapped with the bearing surface of the fixture.
Thirdly, a positioning protrusion 21 is arranged on the upper edge of the end face of the first clamping part 2 and the second clamping part 3, which are used for abutting against the mobile phone frame, the positioning protrusion 21 is smoothly connected with the end face, namely, a transition face in the shape of a line, an arc or a parabola is formed between the positioning protrusion 21 and the end face, when the first clamping part 2 and the second clamping part 3 are matched with and used for clamping the mobile phone frame, if the mobile phone frame is not accurately placed on and completely attached to the bearing face of the jig body 1 or the carrier plate 6, the pressure applied to the mobile phone frame by the transition face has a downward component under the pushing force of the second clamping part 3, and the mobile phone frame is pushed to move downwards and attached to and completely attached or overlapped with the bearing face of the jig or the carrier plate 6.
Optionally, referring to fig. 5, an elastic push rod 22 is disposed in the first clamping portion 2, and the elastic push rod 22 extends out of the first clamping portion 2 to press against an end surface of the mobile phone frame; when the second clamping part 3 moves towards the first clamping part 2 to be matched with the first clamping part 2 to clamp the mobile phone frame, the elastic ejector rod 22 is pressed by the mobile phone frame to generate elastic deformation and is accommodated in the first clamping part 2; when the second clamping part 3 moves away from the first clamping part 2 to release the mobile phone frame, the elastic ejector rod 22 can restore to deform to reversely press the mobile phone frame, so that the mobile phone frame is pushed to the outside of the positioning protrusion 21.
The elastic push rod 22 may include a cylindrical rod 221 and a third elastic element 222. Taking a spring as the third elastic element 222 as an example, the rod 221 and the spring are accommodated in a through hole or a blind hole formed in the first clamping portion 2, one end of the spring is abutted or fixedly connected with one end of the first clamping portion 2 facing the outside of the fixture, and the other end is abutted or connected with the rod 221. The extension length of the spring can enable one end of the rod body 221 to extend out of the first clamping part 2 to be used for abutting against the end face of the mobile phone frame when the spring is in extension, the extension length is larger than the thickness of the positioning protrusion 21 protruding out of or flush with the end face, so that after the mobile phone frame is machined, the elastic ejector rod 22 can transversely push the mobile phone frame, the mobile phone frame is moved out of the positioning protrusion 21, and therefore the mobile phone frame can be taken out by grabbing equipment such as a mechanical arm.
