[0001] The present application relates to the technical field of seat punching equipment, and in particular to a seat punching and positioning tool. Background Art

[0002] The seat of an office chair needs to have threaded holes in order to connect it to the seat base or to connect it to the cushion on the seat, and holes need to be processed at fixed positions.

[0003] A Chinese patent with announcement number CN216680339U discloses a tool for punching holes in seats, including a machine platform, on which a lower support mold for use with the seat is provided, a vertical plate is provided on one side of the lower support mold, a positioning component for use with the lower support mold is rotatably connected to the vertical plate, and a limiting component for limiting the rotation of the positioning component is also provided on the vertical plate.

[0004] During the use of the above technology, only one size of the seat of this type can be drilled, and its use condition is relatively single. When the factory needs to process another size of the seat of this type, the factory needs to manufacture new tooling for positioning processing, resulting in low utilization of the tooling and the need to increase the factory's tooling production costs, which is insufficient. Utility Model Content

[0005] In order to improve the problem of low tooling utilization rate, the present application provides a seat punching and positioning tool.

[0006] The seat punching and positioning tool provided in this application adopts the following technical solution:

[0008] By adopting the above technical solution, workers place chair seats of different sizes on the supporting mold base, and then adjust the positioning position of the chair seat through the positioning parts, and then rotate the positioning frame so that the positioning frame presses the chair seat onto the supporting mold base, and then drill holes through the drilling assembly on the positioning frame. Finally, workers place the chair seat of that size on the supporting mold base and repeatedly drill holes, which is beneficial to improve the utilization rate of drilling holes for chair seats of different sizes, and at the same time reduces the cost of workers making tooling.

[0009] Optionally, the positioning member includes a plurality of positioning columns slidably arranged on the supporting mold base, the positioning columns are used to abut the circumferential edges of the seat, the supporting mold base is provided with a plurality of sliding grooves with inverted T-shaped cross-sections, the sliding grooves correspond one-to-one to the positioning columns, a locking nut slides in the sliding groove, and the positioning column is threadedly connected to the locking nut.

[0010] By adopting the above technical solution, when it is necessary to punch holes in chair seats of different sizes, the worker first loosens the positioning column, places the new seat on the supporting mold base and adjusts the position, then moves the positioning column close to the edge of the seat, and then tightens the positioning column. The locking nut is pressed against the inner wall of the slide groove to position the new seat. After the drilling is completed, the worker only needs to place the seat of the same size on the supporting mold base to quickly achieve positioning.

[0011] Optionally, a protective cover is provided on the positioning column, and the protective cover is used to abut against the edge of the seat.

[0012] By adopting the above technical solution, the protective cover changes the hard contact between the positioning column and the seat into flexible contact, which is helpful to reduce the possibility of the seat being damaged by collision.

[0013] Optionally, the drilling assembly includes a cantilever plate slidably disposed on a positioning frame, a drilling positioning block is disposed on the cantilever plate, a reference drilling groove for drilling is formed on the drilling positioning block, and a fixing piece for fixing the cantilever plate is disposed on the positioning frame.

[0015] Optionally, the fixing member includes a waist-shaped slot hole opened on the positioning frame, and a first bolt is bolted to the cantilever plate, and the first bolt is slidably penetrated through the waist-shaped slot hole.

[0016] By adopting the above technical solution, workers can quickly adjust the position of the cantilever plate by tightening the first bolt. The operation is simple and quick, which helps to reduce the labor difficulty of workers.

[0018] By adopting the above technical solution, the worker loosens the second bolt and then slides and adjusts the drilling positioning block to further align the drilling positioning block with the drilling position on the seat, thereby further improving the accuracy of the drilling position of the seat. At the same time, the U-shaped cavity of the cantilever plate facilitates the drilling tool to pass through for drilling.

[0019] Optionally, a sleeve is sleeved on the second bolt, the sleeve is passed through the cantilever plate, and the sleeve is passed through the adjustment slot.

[0020] By adopting the above technical solution, the sleeve reduces the gap between the second bolt and the adjustment slot, which is beneficial to reducing the possibility of lateral movement of the drilling positioning block under the vibration of the drilling tool, and is beneficial to improving the accuracy of the seat seat drilling position.

[0021] Optionally, the cross section of the adjustment slot is a plurality of interconnected holes.

[0024] By adopting the above technical solution, when the positioning frame presses the seat against the supporting mold base, the worker starts the limit cylinder, and the piston rod of the limit cylinder extends and inserts into the positioning frame, which helps to reduce the possibility of the positioning frame loosening when drilling holes in the seat.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. The worker places the chair seats of different sizes on the supporting mold base, and then adjusts the positioning position of the chair seats through the positioning piece, and then rotates the positioning frame so that the positioning frame presses the chair seats onto the supporting mold base, and then punches holes through the drilling assembly on the positioning frame. Finally, the worker places the chair seats of the size on the supporting mold base and repeatedly punches holes, which is conducive to improving the utilization rate of punching holes for chair seats of different sizes, and at the same time reduces the cost of workers making tooling;

[0027] 2.
