Description

Technical Field

[0001] This utility model relates to the field of seat adjuster technology, and in particular to a positioning and drilling device for manufacturing seat adjusters. Background Technology

[0002] During the production of seat adjusters, the outer shell needs to be drilled, and torsion spring pins need to be installed inside the holes. Generally, production workshops will produce multiple models of adjusters at the same time, so the requirements for the hole diameter are different, and different drilling tools need to be changed on the drilling machine.

[0003] When changing tools, operators usually stop the production line and manually change the tools. Although changing tools is a simple operation, stopping the production line is to protect the safety of the operators, which reduces production efficiency. In order to achieve full automation and improve production efficiency, the tool changing procedure of the punching device needs to be improved. Utility Model Content

A ring of retaining teeth is fixedly installed on the outer wall of the rotating wheel, and the retaining teeth of the rotating wheel mesh with the screw. Multiple mounting slots are evenly distributed on the outer wall of the rotating wheel. A motor is fixedly mounted on the worktable surface, and the output end of the motor is fixedly connected to the end of the screw. The other end of the screw is connected to the worktable surface via a bearing, and the screw is parallel to the worktable surface.

[0015] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings.

[0016] like Figure 1-4The device shown is a positioning and drilling device for producing seat adjusters. It includes a worktable 1 and a tool changing assembly mounted on the worktable 1. The tool changing assembly includes a screw 2, a rotating wheel 6 and mounting slots 7. The screw 2 is rotatably mounted on the table surface of the worktable 1. The rotating wheel 6 is movably mounted above the worktable 1. A ring of teeth is fixedly installed on the outer wall of the rotating wheel 6. The teeth of the rotating wheel 6 mesh with the screw 2. Multiple mounting slots 7 are evenly distributed on the outer wall of the rotating wheel 6. A motor 3 is fixedly mounted on the table surface of the worktable 1. The output end of the motor 3 is fixedly connected to the end of the screw 2. The other end of the screw 2 is connected to the table surface of the worktable 1 through a bearing. The screw 2 is parallel to the table surface of the worktable 1.

[0017] A fixing plate 4 is fixedly installed on the surface of the workbench 1. A connecting pipe 5 is installed on the top of the fixing plate 4 via a bearing. A rotating wheel 6 is fixed to the end of the connecting pipe 5. Multiple sliding grooves 8 are formed on the outer wall of the end of the connecting pipe 5. The number and position of the multiple sliding grooves 8 correspond to the mounting groove 7, and the sliding grooves 8 are connected to the mounting groove 7.

[0018] A cylinder 9 is installed inside the connecting pipe 5. The cylinder 9 is fixedly mounted on the fixing plate 4. A lever 10 is rotatably mounted on the output end of the cylinder 9. The end of the lever 10 abuts against the inner wall of the connecting pipe 5. A fixing member 11 is fixedly mounted on the output end of the cylinder 9. The fixing member 11 is U-shaped. A central rod 12 is fixedly mounted inside the fixing member 11. One end of the lever 10 is sleeved on the central rod 12. The outer wall of the end of the lever 10 is connected to the outer wall of the central rod 12 by a torsion spring.

[0019] Example: When a punching tool needs to be replaced, the external punching mechanism lowers the puncher above the worktable 1, aligning the puncher's tool mounting hole with the mounting slot 7 above the rotating wheel 6. When a corresponding tool needs to be selected, the motor 3 drives the screw 2 to rotate, which in turn drives the rotating wheel 6 to rotate. Simultaneously, the rotating wheel 6 drives the connecting pipe 5 to rotate on the fixed plate 4. After the corresponding mounting slot 7 is aligned with the puncher, the cylinder 9 is activated, pushing the lever 10. The end of the lever 10 rotates within the fixing member 11, and the torsion spring on the central rod 12 drives the lever 10 to rotate. After being pushed by the cylinder 9, the end of the lever 10 enters the sliding groove 8, pushing the tool inside the mounting slot 7, allowing the tool to enter the puncher's tool mounting hole and complete the installation. This enables the puncher to automatically change tools, and the rotating wheel 6 can automatically position a tool of the appropriate size to align with the puncher.
