Description

Technical Field

[0001] This utility model relates to a vulcanization processing fixture, and more particularly to a flipping fixture for vulcanization processing of copper valve parts. Background Technology

[0002] In the manufacturing process of valve stems, the copper parts of the valve stem are usually vulcanized to form the rubber-structured stem portion. Current vulcanization technology involves placing each valve stem individually into a mold tray for batch vulcanization. This manual insertion method is inefficient and cannot meet the efficiency requirements of mass vulcanization processes. Utility Model Content

[0003] The technical problem to be solved by this utility model is that the existing manual insertion method of vulcanizing molds is inefficient. This utility model provides a flipping tool for vulcanizing valve stem copper parts to solve the above problem.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a flipping fixture for vulcanization processing of valve stem copper parts, which is set at the outlet of the conveyor line of the vibrating feeding tray of valve stem copper parts, including a flipping mechanism, a carrier mechanism and a gripping mechanism set above the flipping mechanism and the carrier mechanism, and a pushing mechanism is set at the outlet of the conveyor line to push the valve stem copper parts on the conveyor line toward the flipping mechanism.

[0005] Further: The flipping mechanism includes a flipping seat and a rotating bracket rotatably mounted on the flipping seat. The flipping seat is slidably mounted on the flipping sliding mechanism. A flipping motor that drives the flipping seat to rotate is mounted on the flipping seat. A guide rod and a spring guide rod arranged parallel to the guide rod are horizontally arranged on the rotating bracket. Several pairs of flipping grippers are also arranged in pairs on the rotating bracket. The guide rod and the spring guide rod pass through the flipping grippers. The flipping grippers slide along the guide rod. A return spring is arranged between two adjacent pairs of flipping grippers. A return spring is also arranged between the outermost flipping gripper and the rotating bracket. The return spring is sleeved on the spring guide rod.

[0006] Furthermore: the pushing mechanism includes a pushing cylinder horizontally disposed at the outlet of the feeding tray, and a pushing rod is disposed at the top of the piston rod of the pushing cylinder. The pushing rod extends under the drive of the pushing cylinder to push the valve copper piece at the outlet of the feeding tray to the flipping gripper on the rotating bracket.

[0007] Furthermore: the flipping sliding mechanism includes a first lead screw, a first slider and a first servo motor. The first slider is mounted on the first lead screw. The first servo motor drives the first lead screw to rotate, thereby driving the first slider to move along the first lead screw. The flipping seat is mounted on the first slider.

[0008] Furthermore: the gripping mechanism includes a second lead screw, a second slider, and a second servo motor. The second lead screw is horizontally positioned above the flipping mechanism and the carrier mechanism. The second slider is mounted on the second lead screw. The second servo motor drives the second lead screw to rotate, thereby driving the second slider to move along the second lead screw. A gripping claw that slides vertically is mounted on the second slider.

[0009] Further: The carrier mechanism includes a carrier plate, a third lead screw, a third slider, and a third servo motor. The third lead screw is horizontally arranged, the third slider is mounted on the third lead screw, the third servo motor drives the third lead screw to rotate, thereby driving the third slider to move along the third lead screw, and the carrier plate is mounted on the third slider.

[0010] The beneficial effects of this utility model are that the flipping fixture for the vulcanization processing of copper valve parts uses multiple arranged grippers to clamp the valves fed by the feeding tray one by one in sequence, and then the rotating bracket completes the flipping of the whole, so that they can be automatically picked up and placed into the carrier tray of the vulcanization mold for subsequent processing. The whole process is automated and does not require manual assistance, resulting in high work efficiency. Attached Figure Description

[0018] like Figures 1 to 4 As shown, this utility model provides a flipping fixture for the vulcanization process of valve stem copper parts 13, which is set at the outlet of the conveyor line 1 of the vibrating feeding tray of valve stem copper parts 13. It includes a flipping mechanism 2, a carrier mechanism 3, and a gripping mechanism 4 set above the flipping mechanism 2 and the carrier mechanism 3. A pushing mechanism 5 is provided at the outlet of the conveyor line 1 to push the valve stem copper parts 13 on the conveyor line 1 toward the flipping mechanism 2.

[0019] The flipping mechanism 2 includes a flipping seat 6 and a rotating bracket 7 rotatably mounted on the flipping seat 6. The flipping seat 6 is slidably mounted on the flipping sliding mechanism. A flipping motor 8 that drives the flipping seat 6 to rotate is mounted on the flipping seat 6. A guide rod 9 and a spring guide rod 10 arranged parallel to the guide rod 9 are horizontally arranged on the rotating bracket 7. Several pairs of flipping grippers 11 are also arranged in pairs on the rotating bracket 7. The guide rod 9 and the spring guide rod 10 pass through the flipping grippers 11. The flipping grippers 11 slide along the guide rod 9. A return spring 12 is arranged between two adjacent pairs of flipping grippers 11. A return spring 12 is also arranged between the outermost flipping gripper 11 and the rotating bracket 7. The return spring 12 is sleeved on the spring guide rod 10.

[0020] The pushing mechanism 5 includes a pushing cylinder 14 horizontally disposed at the outlet of the feeding tray. A pushing rod is disposed on the top of the piston rod of the pushing cylinder 14. The pushing rod extends under the drive of the pushing cylinder 14 to push the valve copper part 13 at the outlet of the feeding tray to the flipping gripper 11 on the rotating bracket 7.

[0021] The flipping fixture involved in this application is mainly used in the loading process before the valve stem copper parts 13 are loaded into the carrier during the vulcanization process. The valve stem copper parts 13 to be vulcanized are transported one by one to the vicinity of the flipping fixture through the loading tray. At this time, the valve stem copper parts 13 are arranged with the large end facing upward in the loading tray. By pushing the piston rod of the pushing cylinder 14, the valve stem copper parts 13 that are transported in sequence in the loading tray are pushed one by one from the loading tray into the flipping jaws 11 of the flipping seat 6.

[0022] The flipping grippers 11 on the flipping base 6 are installed in pairs and can slide along the guide rod 9. Each pair of flipping grippers 11 is pushed towards each other by the return springs 12 on both sides, thus achieving the function of clamping the valve stem copper part 13 pushed by the push rod. After the flipping grippers 11 on the flipping base 6 have completed the clamping and transfer of the valve stem copper part 13, the flipping motor 8 will drive the flipping base 6 to rotate, changing the valve stem copper part 13 from the large end facing upward to the large end facing downward, thereby meeting the requirements for subsequent placement in the carrier mechanism 3.

[0023] The flipping and sliding mechanism includes a first lead screw 15, a first slider 16 and a first servo motor 17. The first slider 16 is mounted on the first lead screw 15. The first servo motor 17 drives the first lead screw 15 to rotate, thereby driving the first slider 16 to move along the first lead screw 15. The flipping seat 6 is mounted on the first slider 16.

[0024] After a valve stem copper part 13 is installed on a flipping gripper 11, the position of the flipping seat 6 can be moved by the flipping sliding mechanism. The flipping gripper 11 with the valve stem copper part 13 installed is removed from the pushing position of the push rod, and the flipping gripper 11 with the valve stem copper part 13 to be installed is moved to the pushing rod position. Through this operation, the valve stem copper part 13 can be installed in each flipping gripper 11, completing the switching installation of the valve stem copper part 13 and realizing the valve stem copper part 13 on the flipping seat 6.

[0025] The gripping mechanism 4 includes a second lead screw 18, a second slider 19, and a second servo motor 20. The second lead screw 18 is horizontally arranged above the flipping mechanism 2 and the carrier mechanism 3. The second slider 19 is mounted on the second lead screw 18. The second servo motor 20 drives the second lead screw 18 to rotate, thereby driving the second slider 19 to move along the second lead screw 18. A gripping claw 21 that slides vertically is mounted on the second slider 19.

[0026] The gripper 21 can move up and down vertically to pick up and put down the valve stem copper part 13. The second slider 19 moves back and forth above the flipping mechanism 2 and the carrier mechanism 3. This allows the gripper 21 to pick up the valve stem copper part 13 at the flipping mechanism 2, and then the second slider 19 to move and transfer the valve stem copper part 13 to the top of the carrier mechanism 3. Then the gripper 21 moves down and places the valve stem copper part 13 on the gripper 21 at the carrier mechanism 3.

[0027] The carrier mechanism 3 includes a carrier plate 22, a third lead screw 23, a third slider, and a third servo motor 24. The third lead screw 23 is horizontally arranged, and the third slider is mounted on the third lead screw 23. The third servo motor 24 drives the third lead screw 23 to rotate, thereby driving the third slider to move along the third lead screw 23. The carrier plate 22 is mounted on the third slider.

[0028] The carrier tray 22 is used to place the flipped valve stem copper parts 13. The carrier tray 22 has several positioning holes for placing the valve stem copper parts 13. The gripping claws 21 place the valve stem copper parts 13 into the positioning holes. The gripping mechanism 4 can move the carrier tray 22 to different positions in the positioning holes longitudinally. A movable third slider moves laterally. After placing one valve stem copper part 13 laterally, the carrier tray 22 can be moved laterally to place the valve stem copper parts 13 in a new position laterally. This movement of the carrier tray 22 to different positions in the positioning holes laterally allows the gripping claws 21 to grasp the valve stem copper parts 13 and place them in different areas of the carrier tray 22. The movable third slider increases the placement range of the valve stem copper parts 13 and improves the utilization rate of the carrier tray 22.

[0029] The paired flipping jaws 11 have an outer conical guide portion at their ends, and a V-shaped clamping portion is provided on the rear side of the guide portion. The guide portion facilitates the pushing of the valve stem copper part 13 into the flipping jaws 11, and the clamping portion can lock the rod portion of the valve stem copper part 13. This enables the flipping jaws 11 to reliably hold the valve stem copper part 13, and when it is necessary to remove the valve stem copper part 13 from the flipping jaws 11, the valve stem copper part 13 can be quickly disengaged.
