[0001] This utility model relates to the field of tapping machine technology, specifically to a tapping machine for fastener production. Background Technology

[0002] Nuts are a type of fastener, also known as nuts or bolts. They are typically screwed together with bolts or screws to provide a fastening function and are widely used in assembly and manufacturing. During the manufacturing process of nuts, tapping is an essential processing step. Tapping machines are often used for tapping nuts, and they are machine tools specifically designed for processing internal threads and are widely used in mechanical manufacturing.

[0003] The prior art patent publication number CN221695506U describes a nut tapping machine for fastener production. This patent utilizes a worktable, tapping assembly, vertical plate, top plate, hydraulic cylinder, motor, tapping head, through-hole, fixing mechanism, side plate, rectangular opening, rectangular block, snap-fit ​​groove, support plate, threaded rod, threaded plate, snap-fit ​​plate, guide rod, fixed clamping block, electric push rod, and movable clamping block to facilitate disassembly. This allows the tapping assembly to be easily removed from the worktable, thus greatly facilitating transportation.

[0004] However, the rectangular block in the fixing mechanism of the aforementioned patent is directly fixed to the vertical plate of the tapping assembly. Its position on the tapping assembly is too prominent, and it is inevitable that it will be broken or damaged by collisions with external objects during the separate transportation of the tapping assembly, which will seriously affect the subsequent installation effect of the tapping assembly. Utility Model Content

[0005] To solve the above-mentioned technical problems, a tapping machine for fastener production is provided. This solves the problem that in the prior art, the rectangular block in the fixing mechanism is directly fixed to the vertical plate of the tapping assembly. Its position on the tapping assembly is too prominent, and it is inevitable that it will be broken and damaged by collisions with external objects during the separate transportation of the tapping assembly, which will seriously affect the subsequent installation effect of the tapping assembly.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a tapping machine for fastener production, including a processing table and a tapping assembly disposed on the processing table, a connecting block is vertically disposed on the tapping assembly, a receiving cavity is disposed in the inner wall of the tapping assembly, and a push-pull retraction part is disposed inside the receiving cavity;

[0007] The push-pull retraction part includes a movable plate slidably disposed on one side of the cavity and elastic components disposed at both ends of the movable plate. The other end of the connecting block slides into the cavity and is fixedly connected to the movable plate. A repulsive component is disposed on the other side of the cavity.

[0008] Preferably, the repulsive force assembly includes a rectangular groove vertically disposed on the inner wall of the top of the receiving cavity and a lifting plate seat sliding within the rectangular groove. A second magnetic plate is fixedly embedded on one side of the movable plate, and a first magnetic plate corresponding to the second magnetic plate is fixedly embedded on one side of the lifting plate seat.

[0009] Preferably, the inner wall of the lifting plate seat has a threaded groove, and a control screw that is rotatably connected to the innermost inner wall of the rectangular slide is threaded into the threaded groove.

[0010] Preferably, a control lever is provided on the outer side of the tapping assembly. The control lever rotates and passes into the rectangular slide groove and is connected to the control screw via a bevel gear.

[0011] Preferably, the elastic component includes a fixed cylinder with an internal cavity that is vertically fixed to the inner wall of the rectangular slide groove and a movable block that is slidably disposed in the fixed cylinder. A return spring is fixed between one side of the movable block and the innermost inner wall of the fixed cylinder, and a push-pull rod is vertically fixed to the other side of the movable block. The push-pull rod passes through the fixed cylinder and is fixedly connected to the movable plate.

[0012] Compared with the prior art, the advantages of this utility model are as follows: By setting the push-pull retraction part, the lifting plate seat is moved down and inserted into the inner side of the receiving cavity, so that magnetic plate one corresponds to magnetic plate two. The movable plate can then slide quickly to one side under the magnetic repulsion force and push the connecting block outward, so as to facilitate manual fixation in subsequent use. Conversely, the lifting plate seat is moved up and retracted into the rectangular slide groove, so that magnetic plate one and magnetic plate two do not correspond. This releases the repulsion effect of the movable plate, and the movable plate can then quickly carry the connecting block back to its original position under the elastic component, retracting the connecting block into the receiving cavity and hiding it, so as to prevent the connecting block from protruding too much on the tapping component and being easily damaged by collision during the transport of the tapping component.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0021] Reference Figure 1-5 As shown, a tapping machine for fastener production includes a processing table 1 and a tapping assembly 2 disposed on the processing table 1. A mounting panel 4 is vertically fixed at the edge of the top surface of the processing table 1. A connecting block 3 is vertically disposed on the tapping assembly 2. One end of the connecting block 3 passes through the mounting panel 4. A plug-in mechanism for fixing the mounting panel 4 and the tapping assembly 2 is disposed on the side of the processing table 1.

[0022] The insertion mechanism includes a mounting plate 5 vertically fixed to the side of the processing table 1, a movable plate 6 slidably disposed on the mounting plate 5, and a positioning block 7 vertically fixed to the top surface of the movable plate 6. The connecting block 3 has a fixing port corresponding to the positioning block 7.

[0023] The center of the movable piece 6 is threaded with a transmission screw 8 that is rotatably connected to the mounting piece 5. A guide rod 9 is provided on the side of the transmission screw 8. One end of the guide rod 9 is fixedly connected to the mounting piece 5, and the other end of the guide rod 9 slides through the movable piece 6.

[0024] The knob drives the screw 8, and the movable piece 6 can slide down along the screw 8 under the thread structure, and carry the positioning block 7 out of the fixing hole of the connecting block 3, releasing the fixing effect on the connecting block 3. Then, push the tapping assembly 2 to one side, so that the connecting block 3 is removed from the inner wall of the mounting panel 4, thereby releasing the connection effect between the tapping assembly 2 and the mounting panel 4, which facilitates the separate transportation of the tapping assembly 2.

[0025] Furthermore, referring to Figure 4 As shown, it is worth noting that the tapping assembly 2 has a receiving cavity 10 in its inner wall, and the receiving cavity 10 has a push-pull retraction part inside.

[0026] The push-pull retraction part includes a movable plate 11 that is slidably disposed on one side of the cavity 10 and elastic components disposed at both ends of the movable plate 11. The other end of the connecting block 3 is slidably inserted into the cavity 10 and fixedly connected to the movable plate 11. A repulsive component is disposed on the other side of the cavity 10.

[0027] The repulsion component includes a rectangular slide groove vertically disposed on the inner wall of the top of the receiving cavity 10 and a lifting plate seat 12 sliding in the rectangular slide groove. A magnetic plate 2 14 is fixedly embedded on one side of the movable plate 11, and a magnetic plate 13 corresponding to the magnetic plate 2 14 is fixedly embedded on one side of the lifting plate seat 12.

[0028] By controlling the sliding retraction section, the lifting plate seat 12 moves down and enters the inner side of the receiving cavity 10, so that the magnetic plate 13 corresponds to the magnetic plate 14. The movable plate 11 can then slide quickly to one side under the magnetic repulsion force and push the connecting block 3 outward for subsequent manual fixation. Conversely, by controlling the lifting plate seat 12 to move up and retract into the rectangular slide groove, the magnetic plate 13 and the magnetic plate 14 do not correspond. This releases the repulsion effect of the movable plate 11, and the movable plate 11 can then quickly carry the connecting block 3 back to its original position under the elastic component, retracting the connecting block 3 into the receiving cavity 10 to hide it, so that the connecting block 3 does not protrude too much on the tapping component 2 and is easily damaged by collision during the transport of the tapping component 2.

[0029] Furthermore, refer to Figure 4 As shown, it is worth noting that the inner wall of the lifting plate seat 12 has a threaded groove, and the threaded groove is threaded with a control screw 15 that is rotatably connected to the innermost inner wall of the rectangular slide.

[0030] A control lever 16 is provided on the outside of the tapping assembly 2. The control lever 16 rotates and passes into the rectangular slide groove and is connected to the control screw 15 through a bevel gear.

[0031] The knob control lever 16 and the control screw 15 can rotate synchronously under the transmission of bevel gears, so that the lifting plate base 12 can move up and down along the screw 15 in the threaded structure.

[0032] Furthermore, referring to Figure 4 and Figure 5 As shown, it is worth noting that the elastic component includes a fixed cylinder 17 with an internal cavity that is vertically fixed to the inner wall of a rectangular slide groove and a movable block 18 that is slidably disposed inside the fixed cylinder 17. A return spring 20 is fixed between one side of the movable block 18 and the innermost inner wall of the fixed cylinder 17, and a push-pull rod 19 is vertically fixed to the other side of the movable block 18. The push-pull rod 19 passes through the fixed cylinder 17 and is fixedly connected to the movable plate 11.

[0033] As shown above, when the control lifting plate seat 12 moves down and enters the inner side of the receiving cavity 10, causing the movable plate 11 to slide quickly to one side under the magnetic repulsion force and push the connecting block 3 outward, the movable plate 11 can be simultaneously pulled by the push-pull rod 19 to slide the movable block 18 inside the fixed cylinder 17 and stretch the return spring 20 to deform. In this way, by utilizing the elastic force of the return spring 20, when the control lifting plate seat 12 moves up and retracts into the rectangular slide groove, so that the magnetic plate 13 and the magnetic plate 14 do not correspond, that is, when the repulsion effect of the movable plate 11 is released, the return spring 20 can quickly carry the movable plate 11 and the connecting block 3 back to their original position under the elastic force of the return spring 20.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
