Description

Technical Field

[0001] The utility model relates to the technical field of nut processing, in particular to a fixture for processing door lock nuts. Background Art

[0002] When processing nuts, tapping treatment needs to be carried out on the inside thereof, that is, internal threads are processed inside the nuts; when tapping the nuts, the nuts need to be placed in corresponding hexagonal grooves, so that the nuts can be prevented from rotating and the stability during tapping the nuts can be ensured.

[0003] However, at present, most of the hexagonal grooves for nut limiting are fixed gears. If nuts of different sizes are processed, an additional workbench is required, which will increase the cost of tapping the nuts; there are also some that can replace the mold with a hexagonal groove, but it is fixed by bolts and the disassembly of the bolts is cumbersome and inconvenient; for this reason, this application proposes a fixture for processing door lock nuts.

[0004] In view of the deficiencies in the prior art, the utility model provides a fixture for processing door lock nuts.

[0005] An embodiment of the utility model provides a fixture for processing door lock nuts, including:

[0006] A mounting plate;

[0007] A nut limiting component; the nut limiting component includes a support table fixed on the mounting plate, an installation hexagonal groove is vertically penetrated through the support table, a hexagonal frame is slidably connected in the installation hexagonal groove, and the hexagonal frame can be detachably installed in the installation hexagonal groove through a locking mechanism; a limiting hexagonal groove is arranged at the upper end of the hexagonal frame, a short shaft is fixed at the upper end of the hexagonal frame, a limiting block is fixed on the short shaft, and a torsion spring is installed between the limiting block and the short shaft.

[0008] Further, a blanking groove communicated with the installation hexagonal groove is vertically penetrated through the bottom of the mounting plate.

[0009] Further, the locking mechanism includes a plug rod penetrating through the support table and slidably arranged therewith, a slot is arranged on the hexagonal frame, and the plug rod is slidably connected in the slot to lock the hexagonal frame.

[0010] Further, a pulling block is fixed on the plug rod, a spring is fixed on the pulling block, the other end of the spring is fixed to the support table, and the spring is sleeved outside the plug rod.

[0011] Further, the limiting hexagonal groove and the hexagonal frame are coaxially arranged, and the inscribed circle diameter of the limiting hexagonal groove is greater than the inscribed circle diameter inside the hexagonal frame.

[0014] The utility model can disassemble and replace the hexagonal frame, with simple and convenient operation, and also reduces the cost of nut processing. At the same time, the nut can be limited in position to prevent it from moving with the tapping head, so as to facilitate the subsequent removal of the nut. Description of the Drawings

Detailed Embodiment

[0019] The technical solutions in the utility model will be further described below with reference to the drawings and embodiments.

[0020] As Figures 1 - 3 shown, an embodiment of the utility model provides a fixture for processing a door lock nut, including:

[0021] A mounting plate 1, on which four positioning holes 2 are arranged in a rectangular distribution. The mounting plate 1 can be fixed on the workbench by bolts passing through the positioning holes 2;

[0022] A nut limiting component; the nut limiting component includes a support platform 3 fixed on the mounting plate 1. The support platform 3 is provided with an installation hexagonal groove 4 penetrating up and down. A blanking groove 11 communicating with the installation hexagonal groove 4 is arranged through the bottom of the mounting plate 1 to discharge the chips generated during tapping.

[0023] A hexagonal frame 6 is slidably connected within a hexagonal groove 4. The hexagonal frame 6 can be detachably installed within the hexagonal groove 4 through a locking mechanism. The locking mechanism includes a plug rod 12 that penetrates through and is slidably arranged on a support platform 3. There is a slot 5 on the hexagonal frame 6, and the plug rod 12 is slidably connected within the slot 5 to lock the hexagonal frame 6. To ensure that the plug rod 12 stably inserts into the slot 5, there is also provided: a pull block 9 is fixed on the plug rod 12, a spring 10 is fixed on the pull block 9, the other end of the spring 10 is fixedly connected to the support platform 3, and the spring 10 is arranged outside the plug rod 12. At this time, the spring 10 is in a stretched state, so that the plug rod 12 can be firmly stuck into the slot 5, and the hexagonal frame 6 can be locked.

[0024] A limiting hexagonal groove 7 is provided at the upper end of the hexagonal frame 6. The limiting hexagonal groove 7 is coaxially arranged with the hexagonal frame 6, and the inscribed circle diameter of the limiting hexagonal groove 7 is larger than the inscribed circle diameter inside the hexagonal frame 6. The limiting hexagonal groove 7 is used to place nuts that need to be processed by tapping. If nuts of different models need to be processed, the hexagonal frame 6 can be replaced. The staff manually pulls the pull block 9, and the movement of the pull block 9 drives the movement of the plug rod 12 and the plug rod 12 disengages from the slot 5. At this time, the hexagonal frame 6 no longer resets, and the hexagonal frame 6 can be taken out.

[0025] To take out the hexagonal frame 6, two symmetrically arranged lifting blocks 8 are fixed on the hexagonal frame 6. In this way, with the cooperation of two staff members, one pulls the plug rod 12 to move, and the other staff member can lift the hexagonal frame 6 by lifting the lifting block 8, so as to replace the required model of the hexagonal frame 6, and the operation is simple and fast.

[0026] A short shaft 14 is fixed at the upper end of the hexagonal frame 6, a limiting block 13 is fixed on the short shaft 14, and a torsion spring is installed between the limiting block 13 and the short shaft 14. As Figure 3 shown, at this time the torsion spring is in a normal state, and the limiting block 13 is located above the limiting hexagonal groove 7. In this way, the nuts within the limiting hexagonal groove 7 can be limited. When the tapping is completed and the tapping head rotates in reverse and disengages from the nut, the nut can be limited by the limiting block 13 to prevent it from moving up with the tapping head. After the tapping head leaves, rotate the limiting block 13 so that it no longer limits the nut, and the nut can be taken off.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
