Description

Technical Field

[0001] This utility model relates to the field of nut tapping technology, and in particular to a nut tapping machine. Background Technology

[0002] A nut, also known as a bolt or threaded nut, is a component used with bolts or threaded rods to fasten a fixed part. During the production of nuts, a tapping machine (or thread tapping machine) is used to tap the threads on the nut.

[0003] Currently, there are many types of nut tapping machines, such as disc tapping machines. For example, the prior art of a nut tapping machine can be referenced with the authorization announcement number CN117066611B. In this type of disc tapping machine, the feeding mechanism makes a circular motion and feeds the nuts to the bottom of the tapping rod (i.e., the tap) for tapping. However, it can only process one nut at a time, resulting in low production efficiency and making it unsuitable for processing small-sized nuts.

[0004] In addition, there are multi-channel tapping machines, such as the prior art authorized by CN103406606B, entitled Automatic Nut Tapping Machine. This machine is equipped with multiple feeding tracks, and the nuts are transported by a vibratory feeder to move within the feeding tracks and enter the tapping station for tapping. However, the material discharge of this type of multi-channel tapping machine is not convenient. Each nut tapping route requires a receiving box. In actual operation, the daily work of workers often involves frequently changing the receiving box, so it is not convenient to use.

[0005] Therefore, the present invention aims to provide a nut tapping machine with high production efficiency and convenient yield, so as to solve the problems existing in the prior art. Utility Model Content

[0051] The tap 223 is mounted on the motor shaft 222 of the tapping motor 22. When the tapping motor 22 moves up and down, the tap 223 can enter or leave the tapping station.

[0052] In this embodiment: the feeding and conveying device 3 includes:

[0053] The second bracket 30 is installed on the body 10;

[0054] The first conveyor wheel 31 is rotatably connected to the second bracket 30 and can be controlled by the first conveyor motor 32;

[0055] The first conveyor belt 33 is driven to connect the first conveyor wheels 31;

[0056] The first conveyor belt 33 can feed the nut 5 into the tapping station.

[0057] In this embodiment: the machine body 10 is provided with a clamping mechanism located at the tapping station, wherein the clamping mechanism includes:

[0058] The clamping block can move relative to the tapping station;

[0059] A clamping cylinder 62 is mounted on the machine body 10 and is used to control the clamping block to fix or loosen the nut located at the tapping station.

[0060] In this embodiment, the tapping station has a groove 63 for the tap to pass through, which allows the tap to enter during tapping to ensure that the tapping is carried out normally.

[0061] In this embodiment: the machine body 10 is provided with a discharge port 64 located on one side of the tapping station, wherein the discharge conveying device 4 includes:

[0064] The second conveyor belt 42 is connected between the second conveyor wheels;

[0065] The second conveyor belt 42 is located below the discharge port 64.

[0066] In this embodiment: the machine body 10 is further provided with a discharge structure, wherein the discharge structure includes:

[0067] The unloading block 70 can move relative to the tapping station;

[0068] The unloading cylinder 71 is installed on the machine body 10 and is used to control the movement of the unloading block 70 and push the nut 5 to move towards the discharge port 64.

[0076] During tapping, the worker places the nut onto the first conveyor belt of each feeding and conveying device. When the first conveyor belt starts, the nut moves towards the tapping station. When it moves to one side of the moving part, the clamping cylinder controls the moving part to move and pushes the nut into the tapping station. At the same time, the fixing part clamps the nut. Then, the lifting drive controls the tapping motor to descend. The tapping motor drives the tap to rotate and process the nut. After processing, the tapping motor drives the tap to reverse, and the lifting drive controls the tapping motor to rise, causing the tap to exit the nut, thus completing the processing.

[0077] After processing, the clamping cylinder drives the moving part to loosen the nut, and then the unloading cylinder controls the unloading block to push the nut into the discharge port, and from the discharge port into the second conveyor belt. The processed nut is then transported by the second conveyor belt to the material frame for collection.

[0078] It should be noted that when the clamping cylinder controls the moving part to move, the feeding conveying device stops operating. When the clamping cylinder controls the moving part to fully reset, the feeding conveying device continues to operate and sends the nut into one side of the moving part, so that the moving part can push the nut into the tapping station.
