In order to automate and unmanned parts machining process, a honing production line for precisely drilling engine parts needs to perform pre-honing detection on a workpiece 200 before honing by using a honing machine, and needs to rotate and lift the workpiece 200 before performing pre-honing detection.
However, in the prior art, the parts to be processed are rotated and lifted respectively through two processes, which results in large occupied area and high cost.

The second driving mechanism 7 is provided on the turntable 3 and drives the transfer table 9 to ascend or descend. Therefore, compared with the prior art that two bases 1 are required to be respectively arranged on a bearing table for rotating the workpiece 200 and a bearing table for lifting the workpiece 200, the embodiment has the advantages that the rotatable rotating table 3 is arranged on one base 1, and the liftable conveying table 9 is arranged on the rotating table 3, so that the rotating table 3 and the conveying table 9 are stacked and integrated, the occupied area is reduced, and the cost is lower.
The carrying device 1000 of the present embodiment is further described as follows:
referring to fig. 1, 2 and 3, the base 1 mainly plays a supporting role to support the components of the rotary table 3, the transfer table 9, the first driving mechanism 5 and the second driving mechanism 7 above the base. The bottom surface of the base 1 is used for directly or indirectly contacting with the bottom surface, the top surface of the base 1, i.e., the surface opposite to the bottom surface, is a mounting surface, and the parts such as the rotary table 3, the conveying table 9, the first driving mechanism 5, the second driving mechanism 7, and the like are all positioned on the top surface of the base 1.
The base 1 is provided with a support 10, the support 10 includes a bearing column 101 and a bearing plate 103 connected to each other, the bearing column 101 is fixedly connected to the base 1, and an axial direction of the bearing column 101 is perpendicular to a top surface of the base 1, that is, a first end of the bearing column 101 is connected to the top surface of the base 1, and a second end of the bearing column 101 extends along a direction perpendicular to the top surface of the base 1 and away from the base 1.

The base 1 is provided with a support boss 16, and the support boss 16 mainly functions to support the fixing member 32 and protect the rotation shaft 30. The supporting shaft sleeve 16 is sleeved outside the rotating shaft 30 and is arranged coaxially with the rotating shaft 30.
The fixing member 32 is connected to a second end of the rotating shaft 30 and is rotatably provided on the support boss 16. Specifically, the fixing element 32 is a plate-shaped element, and is parallel to the top surface of the base 1, the bottom surface of the fixing element 32 is connected to the second end of the rotating shaft 30, and is located at an end of the supporting shaft sleeve 16 away from the base 1, wherein the bottom surface of the fixing element 32 is in sliding fit with the top end surface of the supporting shaft sleeve 16, so that when the first driving mechanism 5 drives the rotating shaft 30 to rotate, the rotating shaft 30 can drive the fixing element 32 to rotate on the supporting shaft sleeve 16.
The first drive mechanism 5 comprises a first telescopic member 50 and a transmission member 52. The first end of the first telescopic element 50 is rotatably connected to the base 1, for example, a boss 54 is disposed on the base 1, and the first end of the first telescopic element 50 is pivotally connected to the boss 54.

The first telescopic member 50 is any electric or various cylinder bodies or push-type power devices capable of extending or shortening, such as an air cylinder, a hydraulic cylinder, an electric push rod, etc., and the transmission member 52 drives the rotating table 3 to rotate along with the extension of the first telescopic member 50, so that the conveying table 9 rotates along with the rotation of the rotating table 3. Illustratively, in a state where the first telescopic member 50 is shortened, the rotary table 3 is in the first position, so that the transfer table 9 can receive the workpiece 200 to be inspected or a honing system to be transferred to the rear end with the workpiece 200 to be inspected; in the state where the first extensible member 50 is extended, the rotary table 3 is rotated to the second position, so that the probe head can detect the workpiece 200. Of course, in other embodiments, the first driving mechanism 5 may also be a servo motor, and transmit torque through a transmission component such as a gear, so as to drive the rotating shaft 30 to rotate, so as to drive the workpiece carried on the conveying table 9 to rotate.
The second driving mechanism 7 comprises a lifting cam assembly 70 and a second telescopic member 72, the lifting cam assembly 70 comprises a driving member 701 and a driven member 703, the driven member 703 is connected to the bottom of the conveying table 9, and the driving member 701 is abutted between the top of the rotating table 3 and the driven member 703.
The second telescopic member 72 may be any extendable or retractable electric or various types of cylinders or push-type power devices such as a pneumatic cylinder, a hydraulic cylinder, an electric push rod, etc. The second telescopic member 72 is disposed on the rotary table 3, i.e. mounted on the fixed member 32, and a telescopic end of the second telescopic member 72 is connected to the driving member 701 to drive the driving member 701 to slide relative to the rotary table 3 and the driven member 703 for reciprocating motion. Of course, in other embodiments, the second telescopic element 72 may also be a motor as a driving source, and the motor is connected to a mechanism capable of converting a rotational motion into a linear motion, such as a rack and pinion, a lead screw, or the like, so as to achieve the effect of reciprocating the driving element 701.
The driving member 701 includes two connecting plates and at least two sliding rods. The two connecting plates are oppositely and parallelly arranged, and the sliding rods are parallelly separated into subsections and are connected between the two connecting plates, namely the first end of each sliding rod is connected with one connecting plate, and the second end of each sliding rod is connected with the other connecting plate. At least one slide bar is connected to the telescoping end of the second telescoping piece 72 so that the slide bar can be driven to reciprocate as the telescoping end of the second telescoping piece 72 extends or retracts. Wherein, the length extending direction of the sliding rod is vertical to the extending direction of the connecting plate. A sliding portion 7014 is respectively disposed at two ends of each sliding rod, and the sliding portion 7014 includes a first sliding surface and a second sliding surface opposite to each other, and the first sliding surface is in sliding fit with the rotary table 3, that is, in sliding fit with the top surface of the fixed member 32; the second sliding surface is in sliding engagement with the follower 703. Specifically, the sliding portion 7014 is in a circular pie shape, and the first sliding surface and the second sliding surface are both the circular arc surfaces to reduce the contact friction. In the present embodiment, the number of the slide bars is not particularly limited, but at least two or more, that is, two, three, or four or more, may be used.
The follower 703 is a block, the top of which is connected with the transfer table 9, the bottom surface of the follower 703 is a wedge-shaped surface 7030, and the sliding part 7014 is in sliding fit with the wedge-shaped surface 7030. Therefore, under the action of gravity, when the second telescopic element 72 extends or shortens to drive the sliding portion 7014 to reciprocate, the wedge-shaped surface 7030 of the driven element 703 is always abutted against the sliding portion 7014, and the driven element 703 drives the conveying table 9 to ascend or descend. Specifically, the wedge-shaped surface 7030 includes an outer convex surface and an inner concave surface, and the outer convex surface and the inner concave surface are in arc transition, so that the transfer table 9 can be stably raised or lowered when the sliding portion 7014 slides relative to the wedge-shaped surface 7030. Illustratively, when the second telescopic member 72 is extended, the sliding portion 7014 gradually moves from the outer convex surface to the inner concave surface, so that the conveying table 9 gradually descends; when the second telescopic member 72 is shortened, the sliding portion 7014 is gradually moved from the inner concave surface to the outer convex surface, so that the conveyance table 9 is gradually raised. Of course, when the second telescopic member 72 is extended, the sliding portion 7014 gradually moves from the inner concave surface to the outer convex surface, so that the conveying table 9 gradually rises; when the second telescopic member 72 is shortened, the sliding portion 7014 gradually moves from the outer convex surface to the inner concave surface, and the conveying table 9 gradually descends.
Of course, in other embodiments, the top surface of the starting sliding portion 7014 is also a wedge-shaped face 7030, and the driven member 703 slidably abuts against the wedge-shaped face 7030, that is, as long as one of the driving member 701 and the driven member 703 has the wedge-shaped face 7030, the other of the driving member 701 and the driven member 703 is in sliding fit with the wedge-shaped face 7030.
The transfer table 9 includes two mounting plates 90 disposed oppositely and in parallel, and a plurality of conveying rollers 92 rotatably disposed between the two mounting plates 90. The plurality of conveyor rollers 92 are arranged in parallel and at equal intervals, the length direction of each conveyor roller 92 is perpendicular to the length direction of the mounting plates 90, namely, a first end of each conveyor roller 92 is rotatably connected with one mounting plate 90, and a second end of each conveyor roller 92 is rotatably connected with the other mounting plate 90, so that the plurality of conveyor rollers 92 form a bearing plane capable of bearing the workpiece 200 stably, and each conveyor roller 92 can rotate to enable the workpiece 200 to translate on the plurality of conveyor rollers 92. Of course, the two mounting plates 90 may be connected by two plates through holes at two ends corresponding to the positions of the two mounting plates, so as to increase the connection reliability between the mounting plates 90 and the conveying rollers 92.
In the present embodiment, the rotating platform 3 is provided with a supporting column 34 and a positioning column 36, that is, the supporting column 34 and the positioning column 36 are provided on the top surface of the fixing member 32, and both the axial direction of the supporting column 34 and the axial direction of the positioning column 36 are perpendicular to the top surface of the fixing member 32. Under the condition that the conveying table 9 bears the workpiece 200 and the positioning column 36 descends, the positioning column 36 penetrates through the conveying table 9 and protrudes out of the top surface of the conveying table 9 to be inserted into the workpiece 200, so that the workpiece 200 cannot shake randomly during rotation, and the pre-honing detection of the workpiece 200 by a detection head is facilitated; the supporting column 34 penetrates through the conveying table 9 and abuts against the bottom surface of the workpiece 200 to play a supporting role.
The lower part of the fixed part 32 is provided with a driving motor 94, and the driving motor 94 is in transmission connection with the conveying rollers 92 through a belt, a chain and the like, so that when the conveying table 9 needs to receive the workpiece 200 to be detected, the driving motor 94 drives the conveying rollers 92 to rotate so as to move the workpiece 200 to a position corresponding to the positioning column 36; or after the pre-honing inspection train is completed, the drive motor 94 drives the transport rollers 92 to rotate to transport the workpiece 200 to the rear-end honing system.
Since the structure of the transmission table 9 such as a chain or a belt for transmitting torque loosens to some extent after descending, for this reason, the fixing member 32 is further provided with a tensioning mechanism 96, taking the chain as an example, the tensioning mechanism 96 is inserted into the chain, and can gradually abut against the chain in the process of gradually descending the transmission table 9, so that the chain can keep a tensioned state under the action of the tensioning mechanism 96 and cannot loosen, wherein the tensioning mechanism 96 is a structure commonly used in the art, and therefore, detailed description is not given.
In the present embodiment, the turntable 3 is provided with the contact lever 38, and the contact lever 38 is movable in an arc shape in accordance with the rotation of the turntable 3. The base 1 is provided with a first stopper 12, and the contact lever 38 is in contact with the first stopper 12 in a state where the turntable 3 is located at the first position. Specifically, the contact rod 38 is disposed on the lower surface of the fixing member 32, the total length of the contact rod 38 and the first limiting member 12 is greater than the distance between the lower surface of the fixing member 32 and the upper surface of the base 1, and the first limiting member 12 is located on the moving track of the contact rod 38, so that when the rotating table 3 rotates from the second position to the first position, the contact rod 38 and the first limiting member 12 can contact each other, so that the rotating table 3 can be accurately stopped at the first position, the rotating table 3 is prevented from rotating excessively, and normal receiving or feeding of the workpiece 200 on the conveying table 9 is ensured.
In the present embodiment, the base 1 is further provided with a second stopper 14, and the contact rod 38 contacts the second stopper 14 when the turntable 3 is located at the second position. Specifically, the second limiting member 14 is disposed on the bracket 10, a distance between the contact rod 38 and the top surface of the base 1, where the contact rod 14 and the second limiting member 14 can contact the second limiting member 14, is greater than a distance between the bottom end surface of the contact rod 38 and the top surface of the base 1, and the second limiting member 14 is located on a moving track of the contact rod 38. Therefore, when the rotating platform 3 rotates from the first position to the second position, the contact rod 38 can contact the second limiting member 14, so that the rotating platform 3 can be accurately stopped at the second position, thereby preventing the rotating platform 3 from having a rotating gap and ensuring that the workpiece 200 on the conveying platform 9 is at a position suitable for pre-honing detection. Wherein, the first position and the second position respectively form 90 degrees with the connecting line between the rotating shafts, so that the rotating platform 3 can rotate in the range of 90 degrees.
The working principle of the carrying device 1000 according to the embodiment of the present invention is as follows:
when the carrying device 1000 needs to receive materials, the telescopic ends of the first telescopic part 50 and the second telescopic part 72 are retracted, the rotating table 3 is located at the first position, the sliding portion 7014 is located on the outer convex surface of the wedge-shaped surface 7030, the conveying table 9 is kept to be lifted, the conveying rollers 92 rotate to receive the workpiece 200 to be detected, the workpiece 200 is enabled to gradually translate to the position to be detected on the plane formed by the conveying rollers 92, at the moment, the positioning hole of the workpiece 200 is opposite to the positioning column 36, and the conveying rollers 92 stop rotating.
After the material receiving is completed, the telescopic end of the second telescopic member 72 gradually extends out, so that the sliding portion 7014 gradually slides from the outer convex surface to the inner concave surface along the wedge-shaped surface 7030, the conveying table 9 descends along with the sliding portion, the tensioning mechanism 96 gradually tensions the chain along with the descending of the conveying table 9, the positioning column 36 on the fixing member 32 is gradually inserted into the positioning hole of the workpiece 200 to position the workpiece 200, and the distance between the supporting column 34 and the bottom surface of the workpiece 200 is gradually reduced until the supporting column 34 abuts against the bottom surface of the workpiece 200 to support the workpiece 200.
After the transferring platform 9 is completely lowered, the telescopic end of the first telescopic member 50 gradually extends out, so that the transmission member 52 drives the rotating shaft 30 to rotate in the forward direction, and the transferring platform 9 rotates accordingly, at this time, the contact rod 38 on the lower surface of the fixing member 32 gradually moves away from the first limiting member 12 and gradually approaches the second limiting member 14, and stops rotating after contacting the second limiting member 14, so that the rotating platform 3 rotates to the second position. When the turntable 3 stops at the second position, the detection mechanism starts to operate, and the conveying table 9 is detected before honing.
After the detection mechanism completes the pre-honing detection, the retractable end of the first retractable member 50 is gradually retracted, so that the transmission member 52 is driven to rotate in the opposite direction, and the fixing member 32 also rotates therewith, and at this time, the contact rod 38 below the fixing member 32 gradually moves away from the second limiting member 14 and gradually approaches the first limiting member 12, and stops rotating after contacting the first limiting member 12, so that the rotating platform 3 rotates to the first position.
After the rotary table 3 rotates to the first position, the retractable end of the second retractable member 72 gradually retracts, so that the sliding portion 7014 gradually slides from the inner concave surface to the outer convex surface along the wedge-shaped surface 7030, the conveying table 9 gradually rises, the supporting column 34 gradually moves away from the bottom surface of the workpiece 200, the positioning column 36 gradually separates from the positioning hole of the workpiece 200 until the conveying table 9 completely rises, and the positioning column 36 is completely separated from the positioning hole of the workpiece 200.
After the transfer table 9 is raised to the highest, the conveying roller 92 starts to rotate to convey the workpiece 200 that meets the pre-honing requirement to the honing system at the rear end.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
