A slot corresponding to the moving rod 11 is provided on the slider 6, allowing the moving rod 6 to move. The movable rod 11 can move left and right. A positioning plate 12 is slidably connected to the inner wall of the movable rod 11. The movable rod 11 has a slot corresponding to the positioning plate 12, allowing the positioning plate 12 to move left and right. A cylinder head 17 is placed on the top of the slider 6. A spring seat 19 is provided on the inner wall of the cylinder head 17. A locking piece 18 contacts the top of the spring seat 19. A snap-fit ​​groove corresponding to the locking piece 18 is provided on the cylinder head 17. The locking piece 18 and the cylinder head 17 are connected to limit the installation of the spring seat 19. The above is the existing technology and will not be elaborated further. The outer wall of the movable plate 4 is provided with a movable mechanism, and the inner wall of the moving rod 11 is provided with an adjustment component. The movable mechanism includes a long rod 8, which is fixedly connected to the outer wall of the movable plate 4. The bottom end of the long rod 8 is slidably connected to a moving plate 9. The moving plate 9 has a slot corresponding to the long rod 8, so that the moving plate 9 can move left and right. The inner wall of the moving plate 9 has a pressing groove 10, the upper part of the pressing groove 10 is vertical, and the lower part is inclined.

[0035] Reference Figure 1 , Figure 6 and Figure 7The adjustment component includes a limiting block 14, which is slidably connected to the inner wall of the moving rod 11. The moving rod 11 has a slot corresponding to the limiting block 14, allowing the limiting block 14 to move back and forth. The left end of the inner wall of the limiting block 14 is elastically connected to a locking block 16 via a movable spring 15. When the locking block 16 moves to the left, the movable spring 15 is compressed. When resetting, the elastic force of the movable spring 15 carries the locking block 16 back to its original position. The top of the moving rod 11 has a locking groove 13, which has two sets of slots corresponding to the locking block 16. The limiting block 14 is inserted into the inner wall of the positioning plate 12, which has multiple sets of slots corresponding to the limiting block 14. The locking block 16 is slidably connected to the inner wall of the limiting block 14, which has a slot corresponding to the locking block 16, allowing the locking block 16 to move left and right. The locking block 16 is engaged with the inner wall of the locking groove 13.

[0036] Reference Figures 3-5 The movable plate 9 is movably connected to the inner wall of the support plate 2, and the movable rod 11 is slidably connected to the inner wall of the extrusion groove 10. When the extrusion groove 10 extrudes the movable rod 11, it causes the two sets of movable rods 11 to move closer to each other or separate. The movable plate 9 is movably connected to the inner wall of the worktable 1. The worktable 1 and the support plate 2 are both provided with corresponding slots for the movable plate 9, so that the movable plate 9 can move left and right while moving vertically. The slider 6 is fixedly connected to the movable end of the hydraulic rod 7. The inner wall of the pressing head 5 contacts the top of the locking piece 18, and the pressing head 5 will press the locking piece 18 to move downward.

[0037] Working principle: When the spring seat 19 needs to be installed, the electrically controlled telescopic rod 3 moves the movable plate 4 and the pressing head 5 downwards. Simultaneously, the movable plate 4 moves the long rod 8 and the moving plate 9 downwards. At this time, the pressing groove 10 presses the two sets of moving rods 11 together, causing the two sets of positioning plates 12 to move closer together. The two sets of positioning plates 12 position the cylinder head 17. When the pressing head 5 contacts the locking plate 18, the moving rods 11 enter the vertical section of the pressing groove 10. As the movable plate 4 and the pressing head 5 move downwards, the pressing groove 10 stops pressing the two sets of moving rods 11 together. When the pressing head 5 presses the locking plate 18 against the cylinder head 17... When the slots on the upper part overlap, the slider 6 moves to the left via the electro-hydraulic rod 7. The slider 6 moves to the left along with the positioning plate 12, the moving rod 11, the moving plate 9, and the cylinder head 17. At this time, the locking piece 18 engages with the slot of the cylinder head 17, completing the limiting installation of the spring seat 19. After installation, the moving plate 9, the moving rod 11, and the cylinder head 17 move back to the initial position via the electro-hydraulic rod 7. Then, the moving plate 4 and the pressing head 5 move back to the initial position via the electro-electric telescopic rod 3. At the same time, the pressing groove 10 presses the two sets of moving rods 11, moving the positioning plate 12 back to the initial position, releasing the positioning of the cylinder head 17.

[0038] When the position of the positioning plate 12 needs to be adjusted, manually move the locking block 16 to the left. When the locking block 16 separates from the first slot on the slot 13, manually move the locking block 16 and the limiting block 14 forward. When the limiting block 14 separates from the slot on the positioning plate 12, manually move the positioning plate 12 left and right to adjust its position. When the positioning plate 12 is adjusted, the limiting block 14 coincides with the slot on the positioning plate 12. Manually move the limiting block 14 and the locking block 16 backward. When the locking block 16 is inserted into the slot of the positioning plate 12, the locking block 16 coincides with the slot on the slot 13. Manually release the locking block 16, and use the elastic force of the movable spring 15 to lock the locking block 16 into the slot of the slot 13, thus completing the limiting of the positioning plate 12. By adjusting the position of the positioning plate 12, the positioning plate 12 can clamp cylinder heads 17 of different specifications.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
