Description

[Technical field]

[0001] The utility model relates to the technical field of nut processing, in particular to the technical field of a tapping machine for nut production. [Background technology]

[0002] A nut is a part that is screwed together with a bolt or screw for fastening. It is a component that all manufacturing machinery must use. According to the different materials, it is divided into several types, such as carbon steel, stainless steel, and non-ferrous metals (such as copper). Nuts are usually hexagonal, followed by square.

[0003] When nuts are processed, they will be tapped. At the beginning, tapping was done manually with a handheld tap, which was inefficient and had poor precision. With the development of science and technology, people's requirements for work efficiency are getting higher and higher. Traditional manual production can no longer meet the requirements of quantity and quality in industrial development. Mechanical production has gradually replaced the ancient manual production. Automatic tapping machines can well replace manual production and make nuts. It is safer and more convenient. The models currently on the market are older, with a single structure and function, low work efficiency, and cannot meet production needs.

[0006] 2. Since the device lacks lubrication and chip collection structure, the cutter head is in contact with the inner hole of the nut for a long time, which may cause deformation or jamming, and the chips generated by tapping will accumulate on the working surface, thus affecting the processing process.

[0015] Beneficial effects of the utility model:

[0016] 1. The utility model can perform tapping on multiple nuts one by one through the coordinated use of a rotating disk, a nut station turntable, a placement groove, a nut conveying device, a conveying track, a tapping assembly, and a fixed structure. First, the nuts to be processed are poured into the nut conveying device, and the nuts are conveyed to the placement groove through the conveying track. Then, motor one is started, and the motor one drives the rotating disk to rotate, and the rotating disk drives the nut station turntable to rotate, so that the nut is rotated to the bottom of the tapping assembly. At this time, the nut in the conveying track automatically falls into another placement groove, and this cycle is repeated. When the nut rotates to the bottom of the tapping assembly, the fixed structure fixes the nut, and then the cylinder one drives the piston rod one to descend, and the piston rod one drives the mounting plate to descend, and the tapping head is driven to rotate by the motor two, so as to tap the inner hole of the nut. After the tapping is completed, the staff takes it out from the placement groove, and multiple nuts can be automatically conveyed to the placement groove and tapped one by one. The work efficiency is high, and the problem of low processing efficiency caused by placing nuts one by one in the placement holes is solved.

[0017] 2. The utility model can reduce friction and flush away debris through the coordinated use of lubrication components, oil collection boxes and oil collection grooves. When the nut is in the process of tapping, the lubricating oil will flow out through the oil outlet pipe, and can lubricate the tapping head and the nut, thereby reducing the friction between the tapping head and the nut, reducing the possibility of deformation and jamming, and ensuring that the thread size, depth, angle and other data of the nut tapped meet the specified standards. At the same time, the lubricating oil can also prevent the nut from rusting, thereby improving the processing quality of the nut. The lubricating oil can also flush the debris into the oil collection groove, and flow into the oil collection box through the oil collection groove, and finally separate the lubricating oil from the debris through the filter, thereby solving the problem that the cutter head is easily deformed or jammed due to long-term contact with the inner hole of the nut, affecting the processing process.
