A clamping device for drilling and tapping nuts

Abstract

The invention discloses a clamping device for nut drilling and tapping. The clamping device comprises a bottom plate. First sliding grooves are formed in the middle portions of the two ends of the bottom plate and connected with a first fixing base and a second fixing base at the top end of the bottom plate through first sliding blocks. First fixing plates are arranged at the two ends of one side of the first fixing base and the two ends of one side of the second fixing base. One side of each first fixing plate is connected with a corresponding second fixing plate through an electric telescopic rod. According to the clamping device for nut drilling and tapping, a clamping plate, a fixing ring and a containing groove are arranged, the containing groove is a right hexagonal groove, the distance is reserved between the first sliding grooves, the first sliding grooves are used in cooperation, and fixing of a nut is effectively enhanced. Meanwhile, damage to the device caused by drilling and tapping tools and self-damage to the drilling and tapping tools when punching and tapping are finished are prevented. The whole device is easy to operate and convenient to use. Fixing of machining of the nut is improved, the finished product effective rate of the nut is increased, and time and cost are saved.

Description

technical field [0001] The invention relates to the technical field of metal product manufacturing and processing, in particular to a clamping device for drilling and tapping nuts. Background technique [0002] Nut, a part screwed together with a bolt or a screw for fastening, a component that must be used in all manufacturing machinery According to different materials, it can be divided into carbon steel, stainless steel, non-ferrous metals (such as copper), etc. There are many types of general nuts, such as hexagonal nuts, round nuts, square nuts and so on. Some standards for nuts are relatively clear. Some specification and size standards, material requirements standards, electroplating standards, etc. are relatively clear. Different types of nuts also have different standards, so here is a detailed introduction to the specifications and standards of nuts. [0003] At present, the clamping of nut drilling and tapping generally adopts the clamping of both ends of the nu...

AI Technical Summary

Problems solved by technology

[0003] At present, the clamping of nut drilling and tapping generally adopts the clamping of both ends of the nut. This clamping method is prone to slippage during drilling and tapping, resulting in misalignment of drilling and tapping. Although this kind of crooked nut can continue to be used, it will affect the subsequent locking effect and service life. If it is scrapped or remanufactured, it will increase the cost and delay the construction period.
