Description

Technical Field

[0001] The utility model relates to the technical field of pressing nut thread counter-attack, in particular to a device for pressing nut thread counter-attack. Background Art

[0002] The press nut, also known as a rivet nut or a self-tightening nut, is a nut used on thin plates or sheet metals. It is round in shape and has embossed teeth and a guide groove on one end. Its working principle is to press the embossed teeth into the preset hole of the sheet metal. The hole diameter is slightly smaller than the embossed teeth of the press rivet nut. The pressure causes the teeth of the press rivet nut to squeeze into the plate, causing plastic deformation around the hole. The deformed object is squeezed into the guide groove, thereby producing a locking effect.

[0003] When processing the push nut, it is necessary to tap the inside of the push nut. During the tapping process of the nut, a large amount of debris will be generated. Most of the debris will be discharged, but some small debris may be stuck inside the thread groove and is not easy to be discharged, affecting the later use effect of the push nut.

DETAILED DESCRIPTION

[0020] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1 As shown in FIG. 2 , a nut thread pressing device comprises a processing table 1, support legs 3 are fixedly installed on both sides of the bottom of the processing table 1, moving blocks 5 are slidably connected on both sides of the top of the processing table 1, a second motor 11 is fixedly installed on the side relatively close to the moving block 5, a tapping drill rod 12 is fixedly installed on the output end of the second motor 11, a clamping mechanism 6 is arranged on the top of the processing table 1 and between the moving blocks 5, and a swing mechanism 2 is arranged at the bottom of the processing table 1;

[0022] The swing mechanism 2 includes a first motor 201, which is fixedly installed at the bottom of the processing table 1. A driving disk 202 is fixedly installed at the output end of the first motor 201. A movable rod 204 is movably connected to the front of the driving disk 202. A fan gear 205 is fixedly installed at the bottom of the movable rod 204. A fixed plate 206 is fixedly installed at the bottom of the processing table 1. The fixed plate 206 is located at the front of the movable rod 204. The fixed plate 206 is rotatably connected to the movable rod 204 through a rotating shaft. A tooth plate 207 is meshed at the bottom of the fan gear 205. Side rods 208 are fixedly installed on both sides of the tooth plate 207. A connecting rod 10 is fixedly installed on the surface of the side rod 208. The top of the connecting rod 10 is fixedly connected to the moving block 5.

[0023] The effect achieved by the above components is: by setting a swing mechanism 2 to drive the two moving blocks 5 to move back and forth left and right, the moving block 5 drives the second motor 11 and the tapping drill rod 12 to move back and forth left and right, and the tapping drill rod 12 taps the nut when it approaches the nut. After the tapping is completed, the tapping drill rod 12 moves away from the nut, and the second motor 11 controls the tapping drill rod 12 to turn and exit the inner ring of the nut. At this time, another tapping drill rod 12 approaches the nut and taps the nut. Since the tapping is completed, when tapping again, the debris generated by the first round of tapping in the thread groove can be discharged to avoid the debris being stuck in the thread groove, which plays a role in cleaning the inside of the nut and preventing the installation effect of pressing the nut. Under the action of the second motor 11, the tapping drill rod 12 is driven to rotate, and then the tapping drill rod 12 taps the nut placed on the clamping mechanism 6.

[0024] like Figure 2 As shown, a transmission rod 203 is fixedly mounted on the front side of the driving disc 202 , an empty slot is opened on the inner side of the movable rod 204 , and the other side of the transmission rod 203 passes through the empty slot.

[0025] like Figure 2 As shown, a support plate 7 is fixedly installed between the support legs 3, a guide groove 8 is opened on the top of the support plate 7, and pulleys 9 are arranged on both sides of the bottom of the tooth plate 207. The pulleys 9 are located inside the guide groove 8 and are slidably connected to the guide groove 8.

[0026] The effect achieved by the above components is: by setting the support plate 7, the guide groove 8 and the pulley 9 to cooperate with each other to support the limited sliding of the tooth plate 207, the stability of the tooth plate 207 when moving left and right is improved, and the tooth plate 207 is prevented from moving and deviating.

[0027] like Figure 2 As shown, vertical rods 210 are fixedly installed on both sides of the bottom of the processing table 1, and a limiting sleeve 209 is fixedly installed on the bottom of the vertical rod 210. The limiting sleeve 209 is sleeved on the surface of the side rod 208.

[0028] The effects achieved by the above components are: by setting the vertical rod 210 and the limiting sleeve 209 to cooperate with each other to limit the side rod 208, the stability of the side rod 208 when it reciprocates left and right is improved, and the stability of the tooth plate 207 when it reciprocates left and right is further improved.

[0029] like Figure 1 and Figure 3 As shown, limiting grooves 4 are provided on both sides of the top of the processing table 1, and the top of the connecting rod 10 passes through the limiting groove 4, and the sizes of the limiting groove 4 and the connecting rod 10 are matched.

[0030] The effects achieved by the above components are: by setting the limiting groove 4 for limiting the connecting rod 10, the stability of the connecting rod 10 driving the moving block 5 to slide on the top of the processing table 1 is improved, and the stability of the tapping drill rod 12 during tapping is further improved.

[0031] like Figure 4 As shown, the clamping mechanism 6 includes a placement frame 601, which is fixedly installed on the top of the processing table 1. The front and back sides of the placement frame 601 are both threadedly connected with screws 602, and a clamping plate 603 is provided on the side relatively close to the screw 602.

[0032] The effect achieved by the above components is: by setting the screw 602 to drive the clamp 603 to move, the clamp 603 moves in a relatively close direction, so that the clamp 603 clamps and limits the pressing nut placed on the inner side of the placement frame 601, thereby improving the stability of the pressing nut during tapping.

[0033] The working principle of this nut thread pressing device:

[0034] The pressing nut is placed on the inner side of the placement frame 601, and the screw rod 602 is rotated. The screw rod 602 drives the clamping plate 603 to move, so that the clamping plate 603 clamps and limits the pressing nut. Under the action of the first motor 201, the driving disk 202 is driven to rotate, and then the driving disk 202 drives the transmission rod 203 to rotate, and the transmission rod 203 drives the movable rod 204 to swing back and forth. The movable rod 204 drives the fan gear 205 to swing, so that the fan gear 205 drives the tooth plate 207 to move back and forth, and the tooth plate 207 drives the side rod 208 to move, and the side rod 208 drives the connecting rod 10 and the moving block 5 to move, so that the two moving blocks 5 regularly move back and forth on the top of the processing table 1, and the moving block 5 drives the second motor 11 and the tapping drill rod 12 to move, and the tapping drill rod 12 taps the nut and cleans the inside of the nut.

[0035] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention.
