Description

Technical Field

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

[0002] A nut is a cap that is screwed together with a bolt or a screw to fasten. It is an essential component for all manufacturing machinery. Nuts are relatively common. In addition, in order to meet the need for locking after installation, nuts with holes in the head or holes in the rod are produced. These holes can prevent the bolts from loosening when subjected to vibration. As a result, the use of bolts and nuts with holes in the head has increased in various industries.

[0003] In existing technology, most nut thread-locking hole processing uses simple clamping devices, which may not be able to accommodate nuts of different sizes, resulting in uneven or insufficient clamping force. The nut is prone to displacement during the drilling process, causing dimensional deviations, irregular shapes, and even scrapping of the thread-locking hole. Furthermore, there may be no effective limiting structure to ensure the linear motion of the clamping block during the clamping process, further exacerbating clamping instability. Furthermore, debris may be scattered around the equipment, making it difficult to clean, causing debris to fly everywhere, polluting the processing environment and endangering the health of operators, such as entering the eyes and respiratory tract. This not only increases the workload and cost of manual cleaning, but also, if not cleaned in time, may enter the precision components within the equipment, accelerating equipment wear, affecting normal operation, shortening equipment life, and increasing equipment maintenance costs and downtime. In view of this, we have introduced a perforation fixture for processing nut thread-locking holes. Utility Model Content

The pipe 20 is connected to the surface of the suction fan 7, and the dust suction head 21 is connected to the bottom of the pipe 20 and is located on the side of the drill bit 12. The air supply pipe 28 is connected between the dust box 19 and the suction fan 7, and the debris inside the air supply pipe 28 can enter the interior of the dust box 19. The top of the dust box 19 is connected to a cover plate 23. It should be noted here that a male buckle is installed on the cover plate 23, and a female buckle is installed on the dust box 19, and the male buckle is adapted to the female buckle, so that the cover plate 23 can be locked or opened, but it is not shown in the figure.

[0032] A through groove 11 is provided on the surface of the processing table 9, and the through groove 11 and the processing table 9 are integrally formed. A mounting block 24 is provided on the surface of the processing table 9 on one side of the positioning block 10, and the mounting block 24 is fixed to the processing table 9. The side of the mounting block 24 is connected to the cylinder C27, and the cylinder C27 is connected to the side of the mounting block 24 by bolts. The output end of the cylinder C27 is connected to the arc clamping block 26.

[0033] The side of the arc-shaped clamping block 26 is connected to a T-shaped limiting rod 25 , and the T-shaped limiting rod 25 passes through the mounting block 24 . The arc-shaped clamping block 26 moves linearly along the mounting block 24 stably under the restriction of the T-shaped limiting rod 25 .

[0034] A material discharge chute 14 is provided at the bottom of the processing table 9 , and the material discharge chute 14 and the processing table 9 are integrally formed. The inner bottom wall of the processing box 1 is located below the material discharge chute 14 and is connected to a material storage box 13 for storing debris.

[0035] A motor B5 is connected to one side of the concave frame 4 , and the motor B5 is connected to the side of the concave frame 4 by bolts.

[0036] The two sides of the concave frame 4 are respectively connected with sliders 3, and the sides of the sliders 3 are in contact with the inner side of the processing box 1. The sliders 3 on both sides of the concave frame 4 are in contact with the inner side of the processing box 1, which plays a guiding and stabilizing role, ensuring that the concave frame 4 can be lifted and lowered smoothly.

[0037] The top of the threaded block 17 is connected to the limiting block 16, and a limiting groove 15 for slidingly connecting the limiting block 16 is opened inside the concave frame 4. The limiting groove 15 and the concave frame 4 are integrally formed. The limiting block 16 at the top of the threaded block 17 slides in the limiting groove 15 inside the concave frame 4, limiting the rotation of the threaded block 17 so that it can only move horizontally along the threaded rod 8.

[0038] Specifically, when in use, the nut to be processed with a lock thread hole is placed on the processing table 9, with one side of the nut close to the positioning block 10 to achieve preliminary positioning, and the cylinder C27 is started. The output end of the cylinder C27 pushes the arc-shaped clamping block 26 toward the nut (i.e., toward the positioning block 10). The arc-shaped clamping block 26 is restricted by the T-shaped limit rod 25 and stably moves linearly along the mounting block 24, thereby clamping the nut on the processing table 9 to ensure that the nut will not be displaced during the processing process.

[0039] The cylinder A2 is started, driving the concave frame 4 to move up and down in the processing box 1. The slide blocks 3 on both sides of the concave frame 4 are in contact with the inner side of the processing box 1, playing a guiding and stabilizing role, ensuring that the concave frame 4 can be smoothly raised and lowered. By controlling the stroke of the cylinder A2, the height position of the drilling hole can be accurately adjusted. The motor B5 is started, driving the threaded rod 8 to rotate. Since the threaded block 17 is screwed to the threaded rod 8, and the limit block 16 on the top of the threaded block 17 slides in the limit groove 15 inside the concave frame 4, the rotation of the threaded block 17 is limited, so that it can only move horizontally along the threaded rod 8. Therefore, the horizontal position of the drill bit 12 can be accurately adjusted according to the size of the nut and the position requirements of the lock wire hole;

[0040] When the drill bit 12 is adjusted to the appropriate position, the cylinder B18 is started, pushing the bottom plate 6 downward so that the drill bit 12 is close to the nut. At the same time, the motor A22 is started, driving the drill bit 12 to rotate at high speed. The drill bit 12 feeds downward while rotating to process the thread hole in the nut.

[0041] During the drilling process, a large amount of debris is generated. At this time, the suction fan 7 is started. Under the action of its suction force, the dust collector 21 and the pipe 20 suck the debris around the drill bit 12. The debris enters the air duct 28 through the pipe 20 and is finally collected in the dust box 19. The cover 23 on the top of the dust box 19 can be opened when the dust box 19 needs to be cleaned, which facilitates the cleaning of the collected debris.

[0042] When the thread lock hole of the nut is processed, the cylinder B18 drives the base plate 6 to rise, the drill bit 12 leaves the nut, and the cylinder C27 drives the arc clamp 26 to loosen the nut. The debris generated during the processing falls into the storage box 13 below through the discharge chute 14 at the bottom of the processing table 9, realizing automatic collection and cleaning of the debris. The nut after processing can be removed from the processing table 9, completing a processing cycle.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
