Description

Technical Field

[0001] This utility model relates to the field of workpiece shaping technology, and in particular to a positioning platform for workpiece shaping. Background Technology

[0002] Workpiece shaping refers to the finishing or correction operations performed after machining and manufacturing to ensure that the shape, size, positional accuracy, or surface quality of the workpiece meets the final design requirements. Its core purpose is to correct deformations, errors, or defects generated during machining or processing, and to ensure that the workpiece meets the requirements of drawings or process specifications.

[0003] In existing workpiece shaping processes, the workpiece is placed into the mold groove inside the lower mold by a feeding device. The feeding device mainly uses a robot or manual labor to pick up the workpiece from the hopper and place it into the lower mold. Taking the robot as an example, the robot mainly uses tools such as suction nozzles to pick up the workpiece, thereby realizing the feeding of the workpiece.

[0004] Existing workpiece shaping equipment requires a robotic arm to place the workpiece into the shaping mold during the shaping process. However, after the robotic arm directly picks up the workpiece, due to the irregular shape of the workpiece's outer surface, the robotic arm needs to repeatedly adjust the workpiece to a specified angle before it can be successfully placed into the shaping mold. This operation results in the robotic arm occupying a large space, having low efficiency, and being inconvenient to use. Utility Model Content

[0017] (III) Beneficial Effects

[0018] This utility model provides a positioning platform for workpiece shaping. It has the following beneficial effects:

[0019] 1. The output end of the electric push rod drives the moving plate to move via the L-shaped plate. The moving plate drives the moving block to move via the connecting rod, thereby causing the top positioning block to move closer to the reference block. This causes the positioning block and the positioning protrusion on the top of the reference block to merge. Then, the robot arm grabs the workpiece and inserts it into the positioning protrusion. Under the action of the spring, the two positioning protrusions separate to support the workpiece. The workpiece is then positioned by the arc-shaped surface of the outer surface of the positioning protrusion. The positioning does not require much rotation. The positioning effect of the positioning component improves the positioning efficiency during loading and makes it convenient to use.

[0020] 2. By rotating the worm gear, the worm wheel is driven to rotate, which in turn drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to move on the outer surface of the threaded rod, thereby moving the positioning block on the outer surface of the moving block. This adjusts the distance between the positioning protrusion on the upper surface of the positioning block and the positioning protrusion on the upper surface of the reference block after the moving block and the reference block are engaged, ensuring accurate positioning.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present utility model. This embodiment provides a positioning platform for workpiece shaping, including a housing 1, a robot arm 2 is arranged inside the housing 1, a transverse moving component 3 is arranged inside the housing 1, and a positioning component 4 is arranged between the robot arm 2 and the transverse moving component 3.

[0031] The positioning component 4 includes a base 401 fixedly installed inside the chassis 1. An L-shaped plate 405 is provided on the top of the base 401. A movable plate 409 is fixedly connected to one end of the L-shaped plate 405. A reference block 406 is fixedly connected to the upper surface of the base 401. Several movable blocks 408 are provided inside the reference block 406. A connecting rod 410 is fixedly connected to the side of the movable block 408 near the movable plate 409. A fixed plate 411 is fixedly connected to the side of the reference block 406 near the movable plate 409. One end of the connecting rod 410 passes through the fixed plate 411 and is fixedly connected to the outer surface of the movable plate 409. A compression spring 407 is provided between the movable block 408 and the reference block 406. A positioning block 412 is provided on the top of the movable block 408.

[0032] Specifically, an electric push rod 402 is fixedly installed on the upper surface of the base 401. The output end of the electric push rod 402 is fixedly connected to the side of the short arm of the L-shaped plate 405 away from the connecting plate. A groove is provided on the upper surface of the electric push rod 402. A protrusion that matches the groove is provided on the lower surface of the long arm of the L-shaped plate 405. A fixing block 404 is fixedly connected to the end of the electric push rod 402 away from the moving plate 409. A limit rod 403 is inserted inside the fixing block 404. One end of the limit rod 403 is fixedly connected to the outer surface of the L-shaped plate 405. Through the cooperation of the groove and the protrusion, and the cooperation of the limit rod 403 and the fixing block 404, the movement path of the L-shaped plate 405 is limited, ensuring that the L-shaped plate 405 moves linearly.

[0033] Specifically, the upper surface of the reference block 406 and the upper surface of the positioning block 412 are provided with positioning protrusions. The cross-section of the moving block 408 is cross-shaped. The interior of the reference block 406 is provided with a limiting groove that cooperates with the moving block 408. The outer surface of the positioning protrusion is provided with an arc-shaped surface that cooperates with the inner surface of the workpiece. The movement of the limiting moving block 408 is realized through the cooperation between the moving block 408 and the limiting groove.

[0034] Furthermore, the output end of the electric push rod 402 drives the moving plate 409 to move via the L-shaped plate 405. The moving plate 409 drives the moving block 408 to move via the connecting rod 410, thereby causing the top positioning block 412 to move closer to the reference block 406. This causes the positioning block 412 and the positioning protrusion on the top of the reference block 406 to merge. Then, the robot 2 picks up the workpiece and places it at the merged positioning protrusion, thus directly inserting the workpiece into the positioning protrusion without much rotation for positioning. One end of the robot 2 and the outer surface of the transverse component 3 are provided with suction nozzles for picking up workpieces. The connection relationship, working principle and operation sequence between the robot 2 and the transverse component 3 and other components are existing technologies and are common knowledge known to those skilled in the art, and will not be elaborated further here.

[0035] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, and an adjustment component 5 is provided between the positioning block 412 and the moving block 408.

[0036] Adjustment component 5 includes a threaded rod 502 movably connected to the top of the movable block 408, a threaded sleeve 504 engaged with the outer surface of the threaded rod 502, a mounting block 501 fixedly connected to the outer surface of the threaded sleeve 504, and the top of the mounting block 501 fixedly connected to the lower surface of the positioning block 412.

[0037] Specifically, a rectangular groove is formed on the upper surface of the positioning block 412. The threaded rod 502 is movably connected inside the rectangular groove. A worm gear 503 is movably connected inside the positioning block 412. One end of the threaded rod 502 passes through the inside of the rectangular groove and is fixedly connected to a worm wheel 505. The worm gear 503 and the worm wheel 505 are meshed and connected. Through the cooperation between the worm wheel 505 and the worm gear 503, the threaded rod 502 can be rotated precisely. Furthermore, the unidirectional transmission characteristic of the worm wheel 505 and the worm gear 503 transmission is used to achieve locking. The outer surface of the mounting block 501 fits against the inner wall of the rectangular groove, thereby preventing the threaded sleeve 504 from rotating with the rotation of the threaded rod 502.

[0038] Specifically, the upper surface of the movable block 408 is provided with a limiting groove, and the lower surface of the positioning block 412 is provided with a limiting protrusion that cooperates with the limiting groove. Through the cooperation of the limiting groove and the limiting protrusion, the linear movement of the positioning block 412 is realized.

[0039] Furthermore, by rotating the worm 503, the worm wheel 505 is driven to rotate, which in turn drives the threaded rod 502 to rotate. The rotation of the threaded rod 502 causes the threaded sleeve 504 to move the mounting block 501 on the outer surface of the threaded rod 502, thereby causing the positioning block 412 to move on the outer surface of the moving block 408. This adjusts the distance between the positioning protrusion on the upper surface of the positioning block 412 and the positioning protrusion on the upper surface of the reference block 406 after the moving block 408 and the reference block 406 are engaged, thus ensuring the internal support effect on the workpiece.

[0040] Working Principle: During workpiece shaping, the robotic arm 2 grips the workpiece, and then the output end of the electric push rod 402 drives the moving plate 409 to move via the L-shaped plate 405. The moving plate 409 drives the moving block 408 to move via the connecting rod 410, thereby causing the top positioning block 412 to move closer to the reference block 406. This causes the positioning block 412 and the positioning protrusion on the top of the reference block 406 to merge. Then, the robotic arm 2 grips the workpiece to the merged positioning protrusion, thus directly inserting the workpiece into the positioning protrusion without much rotation for positioning. Then, the electric push rod 402 retracts its output end, and under the reset action of the compression spring 407, the moving block 408 causes the positioning block 412 to separate from the reference block 406, thereby internally supporting the workpiece. The arc surface of the outer surface of the positioning protrusion compresses the workpiece to rotate to the designated position. The positioning protrusion can fit against the inner side of the workpiece, thus achieving the effect of intermediate positioning. Then, the horizontal movement component 3 moves the workpiece laterally. The workpiece is moved above the base 401 to pick up the positioned workpiece and move it to the position of the forming mold, thus completing the forming and loading process. This eliminates the need for the intermediate positioning function of the positioning component 4 and the direct contact between the robot arm 2 and the mold, facilitating positioning and loading. Furthermore, the positioning block 412 can be finely adjusted based on the internal support effect of the positioning protrusion. By rotating the worm gear 503, the worm wheel 505 rotates, which in turn rotates the threaded rod 502. The rotation of the threaded rod 502 causes the threaded sleeve 504 to move the mounting block 501 on the outer surface of the threaded rod 502, thereby moving the positioning block 412 on the outer surface of the moving block 408. This adjusts the distance between the positioning protrusion on the upper surface of the positioning block 412 and the positioning protrusion on the upper surface of the reference block 406 after the moving block 408 and the reference block 406 are engaged, ensuring the internal support effect on the workpiece and preventing inaccurate positioning due to excessive looseness. Finally, the workpiece forming and loading positioning operation is completed.
