Technical Field

[0001] This utility model relates to the field of workpiece cap technology, specifically to a multi-station cap positioning micro-motion device. Background Technology

[0002] A workpiece cap is a metal cap that is interference-fitted onto the workpiece to meet design and usage requirements. Currently, caps are typically assembled individually, leading to low assembly efficiency. Therefore, there is an urgent need to design a multi-station cap positioning micro-motion device to solve this problem. Utility Model Content

[0003] The purpose of this invention is to provide a multi-station cap positioning micro-motion device to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multi-station cap positioning micro-motion device includes a base plate, a sliding plate on the top of the base plate, a workpiece body evenly distributed inside the sliding plate, a mounting shell on the top of the workpiece body, a horizontal plate between the mounting shell and the workpiece body, two screws fixed to the top outer wall of the horizontal plate, two threaded sleeves connected to the internal bearing of the mounting shell, the two screws being threadedly connected to the two threaded sleeves respectively, a worm gear fixed to the outer wall of the threaded sleeve, and a worm connected to the internal bearing of the mounting shell, the worm meshing with the worm gear.

[0006] Furthermore, a handwheel is rotatably connected to one side of the outer wall of the mounting housing, and the output shaft of the handwheel is connected to the worm gear via a key. A column is fixed between the mounting housing and the base plate.

[0007] Furthermore, a guide post is movably inserted inside the horizontal plate, a pressure plate is fixed at the bottom of the guide post, a spring is sleeved on the outside of the guide post, the spring is located between the pressure plate and the horizontal plate, and a clearance opening adapted to the pressure plate is provided at the bottom of the horizontal plate.

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4As shown in the figure, the multi-station cap positioning micro-motion device provided by this utility model includes a base plate 1, a sliding plate 11 is provided on the top of the base plate 1, a workpiece body 10 is uniformly distributed inside the sliding plate 11, a mounting shell 3 is provided on the top of the workpiece body 10, a horizontal plate 5 is provided between the mounting shell 3 and the workpiece body, two screws 6 are fixed on the top outer wall of the horizontal plate 5, two threaded sleeves 4 are connected to the bearing inside the mounting shell 3, the two screws 6 are threadedly connected to the two threaded sleeves 4 respectively, a worm wheel 7 is fixed on the outer wall of the threaded sleeve 4, and a worm 8 is connected to the bearing inside the mounting shell 3, the worm 8 meshes with the worm wheel 7.

[0021] Specifically, in this embodiment, a base plate 1 is included, a sliding plate 11 is provided on the top of the base plate 1, and workpiece bodies 10 are uniformly distributed inside the sliding plate 11. The workpiece bodies 10 are cylindrical, and a mounting shell 3 is provided on the top of the workpiece bodies 10. A horizontal plate 5 is provided between the mounting shell 3 and the workpiece bodies. Two screws 6 are fixed to the top outer wall of the horizontal plate 5. The two screws 6 are symmetrical about the middle of the horizontal plate 5. Two threaded sleeves 4 are connected to the bearing inside the mounting shell 3. The two screws 6 are threadedly connected to the two threaded sleeves 4 respectively. When the threaded sleeves 4 rotate, they can drive the screws 6 to move up and down. A worm wheel 7 is fixed to the outer wall of the threaded sleeve 4. A worm 8 is connected to the bearing inside the mounting shell 3. The worm 8 meshes with the worm wheel 7. When the worm 8 rotates, it drives the worm wheel 7 and the threaded sleeves 4 to rotate.

[0022] This utility model provides a multi-station cap positioning micro-motion device, which drives the worm wheel 7 and the screw sleeve 4 to rotate through the rotation of the worm 8, thereby enabling the screw 6 to drive the horizontal plate 5 to press down on the cap, so that multiple workpiece bodies 10 can complete the cap assembly at one time, thereby improving the efficiency of workpiece bodies 10 in assembling with caps.

[0023] In another embodiment of this utility model, a handwheel 9 is rotatably connected to one side of the outer wall of the mounting shell 3. The output shaft of the handwheel 9 is connected to the worm gear 8 via a key. The handwheel 9 drives the worm gear 8 to rotate. Due to the meshing transmission between the worm gear 8 and the worm wheel 7, and the force-saving effect of the screw sleeve 4 on the screw 6, the rotation of the handwheel 9 can meet the force required for assembling multiple workpiece bodies 10. A column 2 is fixed between the mounting shell 3 and the base plate 1. A guide post 14 is movably inserted into the inside of the horizontal plate 5. A pressure plate 13 is fixed to the bottom end of the guide post 14. A spring 16 is sleeved on the outside of the guide post 14. The spring 16 is located between the pressure plate 13 and the horizontal plate 5. The bottom of the horizontal plate 5 is provided with a relief opening 12 that matches the pressure plate 13. A limit post 19 is fixed on the top outer wall of the pressure plate 13. The limit post 19 can keep the pressure plate 13 and the horizontal plate 5 at a certain distance to prevent the spring 16 from being compressed to the limit. A stop block 15 is fixed on the top of the guide post 14. The stop block 15 and the horizontal plate 5 can form a block, so that the pressure plate 13 can only move slightly within the limit range to prevent the guide post 14 from separating from the horizontal plate 5.

[0024] In another embodiment of this utility model, fixing plates 21 are welded to the outer walls of both sides of the base plate 1. The fixing plates 21 have mounting holes so that the base plate 1 can be fixed by bolts. A slide rail 17 is fixed to the top outer wall of the base plate 1. The slide rail 17 has a "T" shaped cross section. The sliding plate 11 is slidably connected to the slide rail 17. A handle 18 is fixed to one outer wall of the sliding plate 11 so that the sliding plate 11 can be pulled easily by the handle 18. The top outer wall of the sliding plate 11 has evenly distributed insertion holes 20. The workpiece body 10 is inserted into the insertion holes 20 and the workpiece body 10 is positioned by the insertion holes 20.

[0025] Working principle: In use, the sliding plate 11 is pulled by the handle 18, causing it to move out from the bottom of the horizontal plate 5. The workpiece is then inserted into the insertion hole 20 of the sliding plate 11. The sliding plate 11 is then moved so that the workpiece body 10 is located at the bottom of the pressure plate 13. The handwheel 9 drives the worm gear 8 to rotate, which in turn drives the worm wheel 7 and the screw sleeve 4 to rotate. This causes the screw 6 to move the horizontal plate 5 downward. When the distance between the pressure plate 13 and the workpiece body 10 is slightly less than the height of the cap, the cap is pre-positioned on the top of the workpiece. The elastic force of the spring 16 acting on the pressure plate 13 can pre-position the cap to prevent it from falling off. The horizontal plate 5 continues to move downward so that the pressure plate 13 can assemble the cap and the workpiece body 10.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
