[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-5 The present invention provides an internal pressure spring press-in machine, including a base 1, connecting plates 2 fixedly connected to both sides of the top of the base 1, a top plate 3 fixedly connected to the top of the two connecting plates 2, a cylinder 4 provided on the top of the top plate 3, arc-shaped press feet 5 provided on the surface of the two connecting plates 2, a placement groove 6 provided on the surface of the connecting plates 2 near the bottom, a clamping mechanism provided in the placement groove 6, an equipment cavity 7 provided on one side of the top of the base 1, a top cover 71 detachably connected to the inner wall of the equipment cavity 7 near the top, and an adjustable drive mechanism provided in the inner cavity of the equipment cavity 7.

[0032] When using the equipment, the workpiece to be positioned and clamped is placed in the inner cavity of the placement slot 6. Then, the adjustable drive mechanism set in the equipment cavity 7 drives the clamping mechanism to position and clamp the workpiece. After clamping, the cylinder 4 is activated to drive the pressing rod and the arc-shaped pressing foot 5 at the bottom of the top plate 3 to press the ball spring into the workpiece. In the event of motor failure, the equipment can be operated manually to clamp the workpiece normally. If any parts in the equipment cavity 7 are damaged, the operator can disassemble the top cover 71 and then repair the parts in the equipment cavity 7.

[0033] The clamping mechanism includes a rotating groove 8 that is formed on the top of the base 1 and penetrates the equipment cavity 7. A rotating screw 9 is rotatably connected to the inner cavity of the rotating groove 8. Screw sliders 10 with opposite screw directions are symmetrically arranged on the outer contour of the rotating screw 9. A connecting block 11 is fixedly connected to the top of the screw slider 10. A workpiece clamping plate 12 is fixedly connected to the top of the connecting block 11.

[0034] The adjustable drive mechanism drives the rotating screw 9 in the rotating groove 8 to rotate, so that the two screw sliders 10 with opposite screw directions on the rotating screw 9 move closer to each other when the rotating screw 9 rotates. Thus, the moving screw sliders 10 move closer to each other, causing the connecting block 11 and the workpiece clamping plate 12 on the top of the connecting block 11 to move closer to each other, thereby using the workpiece clamping plate 12 to clamp the workpiece, and then the equipment compresses the spring.

[0035] The adjustable drive mechanism includes a drive motor 13 fixedly connected to one side of the inner wall of the equipment cavity 7. One end of the drive motor 13 is provided with a connecting shaft 14 rotatably connected to the inner wall of the equipment cavity 7. A drive gear 15 is rotatably connected to the outer contour of the connecting shaft 14. An adjusting shaft 18 is slidably connected to one end of the rotating screw 9 near the equipment cavity 7. A rotating bearing 17 is fixedly connected to the outer contour of the adjusting shaft 18. A driven gear 19 is provided on the outer contour of the adjusting shaft 18 and meshes with the drive gear 15. An adjusting groove 31 is opened in the inner cavity of the driven gear 19 for the adjusting shaft 18 to be slidably connected. A snap-fit ​​groove 32 is opened in a circumferential array on the inner wall of the adjusting groove 31. A snap-fit ​​rod 33 that matches the snap-fit ​​groove 32 is arranged in a circumferential array on the outer contour of the adjusting shaft 18.

[0036] By activating the drive motor 13 inside the equipment cavity 7, the drive motor 13 drives the active gear 15 on the outer contour of the connecting shaft 14 to rotate, thereby driving the driven gear 19 to rotate. The driven gear 19 drives the locking rod 33. Because the locking rod 33 engages with the locking groove 32 opened in the inner wall of the adjusting groove 31, when the driven gear 19 drives the adjusting shaft 18 to rotate, the adjusting shaft 18 also drives the rotating screw 9 to rotate, thereby enabling the rotating screw 9 to drive the clamping mechanism to clamp the workpiece.

[0037] The adjustable drive mechanism also includes a sliding rod 16 fixedly connected to the outer contour of the rotating bearing 17 near the bottom. A sliding block 30 is fixedly connected to the bottom of the sliding rod 16. A sliding groove 28 is provided on the inner wall of the equipment cavity 7 for the sliding block 30 to be slidably connected. A limiting sliding rod 20 is fixedly connected to the outer contour of the rotating bearing 17 near the top. A limiting groove 21 is provided on the surface of the top cover 71 for the limiting sliding rod 20 to be slidably connected. A limiting plate 22 is fixedly connected to the top of the limiting groove 21. A limiting rod 23 is slidably connected to one side of the top of the limiting plate 22. A toggle block 24 is fixedly connected to the top of the limiting rod 23. A limiting hole 25 adapted to the limiting rod 23 is symmetrically provided on the top of the top cover 71. The adjustable drive mechanism also includes a rotating shaft 26 rotatably connected to the other side of the inner wall of the equipment cavity 7. A second drive gear 27 is provided on the outer contour of the rotating shaft 26. A handle 29 is fixedly connected to the end of the rotating shaft 26 away from the second drive gear 27.

[0038] After the drive motor 13 is damaged, the operator moves the limit rod 23 upward, causing it to move upward and thus no longer engage with the limit hole 25 on the top side of the top cover 71. Then, the limit plate 22 is moved, driving the limit slide rod 20. Because the outer contour of the adjusting shaft 18 is fixed to the inner ring of the rotating bearing 17, and the limit slide rod 20 and sliding rod 16 are fixed to the outer ring of the rotating bearing 17, when the limit slide rod 20 slides in the limit slide groove 21, it drives the rotating bearing 17 to move, causing the rotating bearing 17 to drive the sliding rod 16 and the sliding block 30 at the bottom of the sliding rod 16 to slide in the sliding groove 28 opened at the bottom of the inner wall of the equipment cavity 7. When the adjusting shaft 18 moves... This also allows the locking rod 33 on the outer contour of the adjusting shaft 18 to slide in the locking groove 32 opened on the inner wall of the adjusting groove 31. When the limiting slide rod 20 can no longer move, the limiting rod 23 on the limiting plate 22 can be locked with the limiting hole on the other side of the top cover 71, thus completing the adjustment of the adjusting shaft 18. This allows the driven gear 19 on the adjusting shaft 18 to mesh with the driving gear 27 on the rotating shaft 26. Then, the operator turns the handle 29 to drive the rotating shaft 26 to rotate, which in turn drives the adjusting shaft 18 and the rotating screw 9 to rotate. This ensures that the rotating screw 9 can still drive the clamping mechanism to run even if the drive motor 13 is damaged, thus ensuring the normal operation of the equipment.

[0039] Fixing bolts 34 are provided at the four corners of the top of the top cover 71, and fixing blocks are fixedly connected to the inner wall of the equipment cavity 7. The surface of the fixing blocks is provided with threaded holes that are compatible with the fixing bolts 34.

[0040] When the drive motor 13 is damaged, the operator continues to work manually. After the factory finishes a day's production, the maintenance personnel can shut down the equipment, remove the fixing bolts 34 on the top cover 71, so that the fixing bolts 34 are separated from the threaded holes on the fixing block, and then remove the top cover 71 on the fixing block. Finally, the operator can repair and replace the damaged drive motor 13.

[0041] Working principle: First, by starting the drive motor 13 in the equipment cavity 7, the drive motor 13 drives the active gear 15 on the outer contour of the connecting shaft 14 to rotate. The active gear 15 drives the driven gear 19 to rotate. The driven gear 19 drives the locking rod 33. Because the locking rod 33 engages with the locking groove 32 opened in the inner wall of the adjusting groove 31, when the driven gear 19 drives the adjusting shaft 18 to rotate, the adjusting shaft 18 also drives the rotating lead screw 9 to rotate. This causes the two lead screw sliders 10 with opposite thread directions on the rotating lead screw 9 to move closer to each other when the rotating lead screw 9 rotates. This causes the connecting block 11 and the workpiece clamping plate 12 on the top of the connecting block 11 to move closer to each other, thereby using the workpiece clamping plate 12 to clamp the workpiece.

[0042] Secondly, after the equipment clamps the workpiece, the cylinder 4 is activated to drive the pressing rod and the arc-shaped pressing foot 5 at the bottom of the top plate 3 to move, thereby pressing the ball spring into the workpiece.

[0043] Secondly, after the drive motor 13 is damaged, the operator moves the limit rod 23 upward, causing the limit rod 23 to move upward, so that the limit rod 23 is no longer engaged with the limit hole 25 on the top side of the top cover 71. Then, the limit plate 22 is moved to drive the limit slide rod 20. Because the outer contour of the adjusting shaft 18 is fixed with the inner ring of the rotating bearing 17, the limit slide rod 20 and the sliding rod 16 are fixed with the outer ring of the rotating bearing 17. When the limit slide rod 20 slides in the limit slide groove 21, it drives the rotating bearing 17 to move, so that the rotating bearing 17 drives the sliding rod 16 and the sliding block 30 at the bottom of the sliding rod 16 in the sliding groove opened at the bottom of the inner wall of the equipment cavity 7. When the adjusting shaft 18 moves, the locking rod 33 on the outer contour of the adjusting shaft 18 also slides in the locking groove 32 opened in the inner wall of the adjusting groove 31. When the limiting slide rod 20 can no longer move, the adjustment of the adjusting shaft 18 is completed, so that the driven gear 19 on the adjusting shaft 18 meshes with the driving gear 27 on the rotating shaft 26. Then, the operator turns the handle 29 to drive the rotating shaft 26 to rotate, so that the rotating shaft 26 drives the adjusting shaft 18 and the rotating screw 9 to rotate. Thus, even if the drive motor 13 is damaged, the rotating screw 9 can still drive the clamping mechanism to run, ensuring the normal operation of the equipment.

[0044] Finally, when the drive motor 13 needs to be repaired, use a wrench to remove the fixing bolt 34 on the top cover 71, so that the fixing bolt 34 is separated from the threaded hole on the fixing block. Then, remove the top cover 71 on the fixing block. Finally, the operator can repair and replace the damaged drive motor 13.

[0045] 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.
