Description

Technical Field

[0001] This utility model relates to the technical field of camshaft cover processing equipment, specifically a camshaft cover processing fixture. Background Technology

[0002] The camshaft is installed in a double row of camshaft holes in the camshaft cover. The double row of camshaft holes in the camshaft cover is semi-circular, so the camshaft cover needs to be punched.

[0003] This utility model, proposed by Chinese Patent Publication No. CN216780001U, relates to the technical field of camshaft cover processing equipment, specifically a camshaft cover processing fixture. It includes a worktable, a fixture base, and a clamping device. The clamping device includes a bracket, a sliding seat, a drive assembly, and a clamping plate. Slide grooves are provided on both sides of the bracket, and the sliding seat is slidably connected to the slide grooves. A connecting plate is provided at the end of the sliding seat near the bracket, and a clamping plate is provided at the end of the sliding seat away from the bracket. A drive assembly is provided on the mounting plate, and the output end of the drive assembly corresponds to the connecting plate. When the camshaft cover to be processed is placed on the fixture base, the drive assembly is activated, and the sliding seat slides on the slide groove via the connecting plate, thereby controlling the clamping plate to move towards the bottom of the bracket, thus clamping the camshaft cover to be processed on the fixture base. Using this structure makes clamping the camshaft cover more convenient.

[0004] When implementing the above solution, the applicant found that in the process of machining camshaft covers, it is often necessary to complete the drilling of one camshaft cover before the replacement and clamping of the next camshaft cover can be carried out. However, the camshaft cover machining fixture does not have the function of machining and replacing camshaft covers, resulting in low machining efficiency and increased waiting time. Based on this, this utility model designs a camshaft cover machining fixture to solve the above problems. Utility Model Content

[0025] Please refer to Figures 1-4A camshaft cover machining fixture includes: a work plate 1, a support frame 2 mounted on the top of the work plate 1, an electric push rod 3 mounted in the inner cavity of the support frame 2, a lifting plate 4 mounted on the bottom of the electric push rod 3, and a drill 5 mounted on the bottom of the lifting plate 4; a conversion mechanism located on the top of the work plate 1 and used for converting between part drilling and part removal, the conversion mechanism including a drive assembly and a rotating assembly, the drive assembly located on the top of the work plate 1 and used to drive the rotation of the rotating assembly, the rotating assembly located on top of the drive assembly and used for converting between the part drilling and part removal positions; and a clamping mechanism located on top of the rotating assembly and used for clamping and fixing the part.

[0026] The drive assembly includes a rotating frame 6 mounted on the top of the work plate 1. A first mounting base 7 is installed in the inner cavity of the rotating frame 6. A rotary motor 8 is installed in the inner cavity of the first mounting base 7. A rotating shaft 9 is installed on one side of the output shaft of the rotary motor 8. A driving bevel gear 10 is installed on one side of the rotating shaft 9. A driven shaft 11 is installed in the inner cavity of the rotating frame 6. A driven bevel gear 12 is installed on the outer ring of the driven shaft 11. The driving bevel gear 10 and the driven bevel gear 12 mesh with each other. A rotating rod 13 is installed on the top of the driven shaft 11. The rotating assembly includes a rotating plate 14 installed on the top of the rotating rod 13. A groove 15 is opened on the top of the rotating frame 6. A ball 16 is installed in the inner cavity of the groove 15. A sliding rod 17 is installed on the top of the ball 16. The top of the sliding rod 17 is connected to the rotating plate 14. Multiple sets of sliding rods 17 and balls 16 are arranged in a circumferential array.

[0027] In this embodiment of the utility model, the electric push rod 3 is activated, which pushes the lifting plate 4 to move up and down. The drill 5 is located at the bottom of the lifting plate 4. Therefore, as the lifting plate 4 moves, the drill 5 can accurately align with the camshaft cover to be processed for drilling.

[0028] Please refer to Figures 1-4 The clamping mechanism includes a clamping frame 18 mounted on the top of the rotating plate 14. A second mounting base 19 is mounted on one side of the clamping frame 18. A clamping motor 20 is mounted in the inner cavity of the second mounting base 19. A bidirectional lead screw 21 is mounted on one side of the output shaft of the clamping motor 20. A moving block 22 is threaded to the outer ring of the bidirectional lead screw 21. A clamping plate 23 is mounted on the front of the moving block 22. A limit assembly is installed in the inner cavity of the clamping frame 18. The limit assembly includes two sets of limit rods 24 installed in the inner cavity of the clamping frame 18. The limit rods 24 are arranged in two sets and symmetrically distributed. The limit rods 24 are inserted into the inner cavity of the moving block 22.

[0029] Telescopic rods 25 are installed between the support frame 2 and the lifting plate 4. There are two sets of telescopic rods 25, which are symmetrically distributed. Support rods 26 are installed at the bottom of the working plate 1. There are four sets of support rods 26, which are distributed in a rectangular array.

[0030] In this embodiment of the utility model, the clamping motor 20 is started, and the start of the clamping motor 20 can drive the bidirectional lead screw 21 to rotate. The outer ring of the bidirectional lead screw 21 is threadedly connected to the moving block 22. As the bidirectional lead screw 21 rotates, the moving block 22 will move in the opposite direction along the limiting rod 24 under the restriction of the limiting component. As the moving block 22 moves, the clamping plate 23 can release the camshaft cover.

[0031] In use, firstly, the rotary motor 8 is started by the drive assembly. The output shaft of the rotary motor 8 drives the rotating shaft 9 to rotate. Since the driving bevel gear 10 mounted on the rotating shaft 9 meshes with the driven bevel gear 12 on the driven shaft 11, the driven shaft 11 will rotate along with the rotating shaft 9. The rotation of the driven shaft 11 further drives the rotating plate 14 and its camshaft cover to rotate via the rotating rod 13, rotating the unprocessed camshaft cover to the bottom of the drill bit 5 position.

[0032] When the unprocessed camshaft cover is at the bottom of the drill 5, the electric push rod 3 is activated, which pushes the lifting plate 4 to move up and down. The drill 5 is at the bottom of the lifting plate 4, so as the lifting plate 4 moves, the drill 5 can accurately align with the camshaft cover to be processed for drilling.

[0033] While the camshaft cover on the left is being drilled, the operator can disassemble the camshaft cover on the right that has been machined. At this time, the clamping motor 20 is started. The start of the clamping motor 20 can drive the bidirectional lead screw 21 to rotate. The outer ring of the bidirectional lead screw 21 is threadedly connected to the moving block 22. As the bidirectional lead screw 21 rotates, the moving block 22 will move in the opposite direction along the limit rod 24 under the restriction of the limit component. The clamping plate 23 is installed on the front of the moving block 22. As the moving block 22 moves, the clamping plate 23 can release the camshaft cover, making it easy for the operator to remove it.

[0034] With the camshaft cover removed, the worker can place the unprocessed camshaft cover above the rotating plate 14. A support frame 2 is installed on the top of the work plate 1, and an electric push rod 3 is installed in the inner cavity of the support frame 2. The push rod is activated by the clamping motor 20, which drives the clamping plate 23 to clamp the new camshaft cover. The clamping mechanism is located on top of the rotating assembly and is used for clamping and fixing the part. The rotating assembly is located on top of the drive assembly and is used for switching between the part drilling and part removal positions. The drive assembly is located on top of the work plate 1 and is used to drive the rotation of the rotating assembly. The switching mechanism is located on top of the work plate 1 and is used for switching between the part drilling and part removal positions, thus enabling simultaneous drilling and replacement of the camshaft cover. A telescopic rod 25 is installed between the support frame 2 and the lifting plate 4. Two sets of telescopic rods 25 are symmetrically distributed. Support rods 26 are installed at the bottom of the work plate 1. Four sets of support rods 26 are arranged in a rectangular array.
