Description

Technical Field

[0001] This utility model relates to the field of PPS composite material technology, and in particular to an auxiliary tooling for processing PPS composite materials. Background Technology

[0002] PPS composite material is a high-performance engineering plastic with PPS resin as the matrix and reinforced or modified by adding fibers, fillers or functional additives. It has excellent high temperature resistance, chemical corrosion resistance, mechanical strength and dimensional stability, and is widely used in automotive, electronics, aerospace and other fields. When processing PPS composite materials, it is usually necessary to clamp and fix them for easy processing.

[0003] However, in existing equipment, most PPS composite materials cannot be flipped after being clamped and fixed. When processing the bottom of the material, the operator needs to repeatedly disassemble and assemble the clamp, which is cumbersome and affects the processing efficiency. Therefore, an auxiliary tooling for processing PPS composite materials is proposed. Utility Model Content

[0007] As a further description of the above technical solution:

[0008] A worm gear is fixedly connected to the rotating rod. The worm gear meshes with the worm. The worm drives the worm gear to rotate, and the worm gear drives the rotating column to rotate through the rotating rod. The rotating column causes the PPS composite material being held to flip.

A second sliding block is slidably connected to each sliding column. One side of each second sliding block is fixedly connected to one side of a corresponding second fixed frame. An L-shaped moving column is fixedly connected to one side of each second sliding block. A snap-fit ​​groove is formed at one end of each L-shaped moving column. A snap-fit ​​block is snapped into each snap-fit ​​groove. A snap-fit ​​hole is formed on one side of each snap-fit ​​block. A push plate is fixedly connected to one side of each push plate. Four second sliding rods are slidably connected through one side of each push plate. One end of the four second sliding rods on the same side is fixedly connected to a clamping plate.

Each clamping plate 16 has a pressure sensor 17 embedded in one side, and each pressure sensor 17 is electrically connected to the PLC control module 29. Each clamping plate 16 has an anti-slip pad 18 fixedly connected to one side. The anti-slip pad 18 increases the friction between the pad and the PPS composite material, preventing the PPS composite material from falling off during movement. The first servo motor 4 drives the first threaded rod 3 to rotate. The first threaded rod 3 drives the moving block 5 to move, causing the two clamping plates 16 on one side of the moving block 5 to move to the appropriate clamping position of the PPS composite material.

The clamping force is adjusted by the signal feedback from the pressure sensor 17 to avoid excessive clamping force that could damage the surface of the PPS composite material.

[0037] To achieve the purpose of disassembly and assembly, the quick-release structure 12 includes a connecting frame 121 fixedly connected to one side of the L-shaped moving column 11. A first sliding rod 122 is slidably connected through one side of the connecting frame 121. A locking post 123 is fixedly connected to one end of the first sliding rod 122.

One side of the column 123 is fixedly connected, and the other end of the first sliding rod 122 is rotatably connected to a toggle handle 124. One side of the toggle handle 124 is in contact with the outer side of the connecting frame 121. When the toggle handle 124 is toggled, the toggle handle 124 drives the first sliding rod 122 to move, and the first sliding rod 122 drives the snap-fit ​​column 123 to move, so that the snap-fit ​​column 123 is disengaged from the snap-fit ​​hole and the return spring 125 is compressed. Then the snap-fit ​​block 13 is pulled out, which makes it convenient for the staff to replace the matching clamping plate 16 according to the shape of the PPS composite material.

[0038] Working principle: The PPS composite material is placed on the upper surface of the base 1, between two clamping plates 16. Then, the PLC control module 29 controls the first servo motor 4, which drives the first threaded rod 3 to rotate. The first threaded rod 3 drives the moving block 5 to move, so that the two clamping plates 16 on one side of the moving block 5 move to the appropriate clamping position of the PPS composite material. Then, the PLC control module 29 controls the third servo motor 23, which drives the second threaded rod 22 to rotate. The second threaded rod 22 drives the pushing block 24 to move. The pushing block 24 moves through the first... The sliding block 25 drives the two first fixed frames 26 to move. The first fixed frames 26 drive one end of the corresponding push column 27 to move. The other end of the push column 27 drives the second sliding block 101 to slide on the corresponding sliding column 10 through the second fixed frame 28. The second sliding block 101 drives the corresponding L-shaped moving column 11 to move. The L-shaped moving column 11 drives the corresponding push plate 14 to move through the snap-fit ​​block 13. The push plate 14 drives the clamping plate 16 to move through the second sliding rod 15, so that the anti-slip pads 18 on the two clamping plates 16 are clamped on both sides of the PPS composite material and the buffer spring 1 is compressed. 9. To achieve flexible clamping, the clamping force is adjusted based on the feedback signal from the pressure sensor 17, preventing excessive clamping force from damaging the surface of the PPS composite material. The first servo motor 4 drives the first threaded rod 3 to rotate, which in turn drives the moving block 5 to move upward, moving the clamped and fixed PPS composite material to an appropriate position, providing rotation space for the rotating column 9. After the movement is completed, the PLC control module 29 controls the second servo motor 701, which drives the rotating shaft 702 to rotate. The rotating shaft 702 drives the worm gear 703 to rotate, and the worm gear 703 drives the worm wheel 702 to rotate. 04. Rotation: The worm gear 704 drives the rotating column 9 to rotate via the rotating rod 8. The rotating column 9 causes the clamped PPS composite material to flip, making it easier for workers to process the bottom of the PPS composite material without repeatedly disassembling and assembling the fixture, thereby improving processing efficiency. Move the toggle handle 124, which drives the first sliding rod 122 to move. The first sliding rod 122 drives the locking post 123 to move, causing the locking post 123 to disengage from the locking hole and compress the return spring 125. Then, the locking block 13 is pulled out, making it convenient for workers to replace the matching clamping plate 16 according to the shape of the PPS composite material.
