Description

Technical Field

[0001] The invention relates to the technical field of nut fastener manufacturing and processing, in particular to nut fastener manufacturing and processing equipment. Background Art

[0002] When manufacturing nuts, they need to be tapped. Tapping, also known as threading, refers to using a certain torque to screw the tap into the bottom hole to be drilled to produce an internal thread. Nuts, also known as nuts, are parts that are screwed together with bolts or studs to play a fastening role. The internal threads are processed by tapping the nuts with a tapping machine.

[0003] For example, a typical nut fastener manufacturing and processing equipment in the prior art is such as authorization number CN116786913B, a nut tapping machine, including a workbench; a column is fixedly connected to the top surface of the workbench near the edge; a transmission box is slidably connected to the surface of the column; a main shaft is rotatably connected to the side of the bottom surface of the transmission box away from the column; a collet is fixedly connected to the bottom surface of the main shaft; a limit ring is fixedly connected to the inner wall of the collet; a tool handle is arranged in the collet; a plurality of uniformly arranged limit plates are fixedly connected to the top surface of the tool handle, and the limit plates are elastic; a plurality of limit grooves adapted to the limit plates are opened on the surface of the limit ring; by making the limit plates and the limit rings rotate relative to each other, the main shaft drives the limit ring to rotate idly, and the transmission box stops descending after receiving the electrical signal sent by the torque sensor, thereby protecting the tap and preventing the tap from continuing to be rotated down and causing the tap to break, thereby protecting the production tools and ensuring the safety of the surrounding workers during production.

[0004] For another example, the nut fastener manufacturing and processing equipment in the prior art is typically such as publication number CN116329677A, a rivet nut tapping machine, including a workbench, a turntable is rotatably installed on the workbench, a tapping mechanism is installed on the right side of the turntable, a plurality of through holes are arranged on the outer ring of the turntable, a tapping station is arranged at a position matching the tapping mechanism on the workbench, a vertical through slot is opened at the tapping station, a positioning column is arranged in the through slot, the positioning column runs through the workbench, a lifting cylinder is connected to the bottom of the positioning column, a waste discharge slot is connected to one side of the through slot, a waste box is connected to the waste discharge slot, and a clamping mechanism is arranged on both sides of the tapping station. The present invention positions the thin-walled part of the rivet nut from the bottom through a liftable positioning column, and then clamps the nut, so that the limit is more accurate and the processing accuracy is guaranteed; a liftable stud is arranged at the center of the positioning column, and a detection block is arranged on the stud. Before tapping, the tap is first approached to the stud for detection to ensure that the nut and the tap are on the same central axis, thereby improving the tapping accuracy.

[0005] For another example, a typical nut fastener manufacturing and processing equipment in the prior art is authorization number CN117961194B, which is an automatic nut tapping machine, including a processing seat, two supporting panels are fixedly installed above the processing seat, a receiving seat is arranged above the processing seat and in the middle of the two supporting panels, and the receiving seat is used to receive the nut, and a driving seat is installed above the processing seat through a support rod, and a driven rod is rotatably installed at the bottom of the driving seat, and a tapping cone rod is fixedly connected to the bottom of the driven rod, and a fixing mechanism is arranged on the upper surfaces of the two supporting panels; the driven rod drives the tapping cone rod to tap the inside of the nut, and after one tapping is completed, the nut can be automatically ejected under the action of the ejecting mechanism of the receiving seat, thereby avoiding the problem in the prior art that when tapping the nut, the nut is too close to the external clamping mechanism and the external groove, making it difficult for the staff to take it out, and facilitating the subsequent tapping of different nuts.

[0006] After the existing nut fastener manufacturing and processing equipment completes the tapping process of the nut, there will be burrs on the edge of the nut hole. Generally, additional grinding equipment is required to chamfer and grind the edge, which makes it difficult to achieve the integrated effect of tapping and grinding, which will reduce the processing efficiency. In view of the above problems, the existing equipment needs to be improved. Summary of the invention
