Problems solved by technology

Before processing, a good positioning effect is not guaranteed. Too tight clamping force will also cause material deformation and wire breakage during wire cutting of external teeth.
This method has poor positioning accuracy, cumbersome operation, and relies on processing experience
At the same time, when this method processes multiple products, the dimensional consistency is poor, and the coaxiality is easy to be out of tolerance, which will lead to difficulty in product assembly or even scrapping

Abstract

The invention provides an internal-and-external tooth structure machining device of tooth-shaped linings. The internal-and-external tooth structure machining device comprises a pressing plate, a mainbody, a positioning ring and a positioning clamp. The positioning ring can move axially in a central through hole of the main body and can be detachably fixed to the side wall of the main body. The pressing plate is detachably fixed to the top of the main body and used for pressing tooth-shaped lining blanks. The main body can be detachably fixed into the positioning clamp. According to the internal-and-external tooth structure machining device, clamping is convenient, positioning is accurate, linear cutting machining of large-batch and small-batch flexible adjusting of the tooth-shaped linings can be achieved.

Description

technical field [0001] The invention belongs to the technical field of fastener manufacturing equipment, and in particular relates to a device for processing inner and outer tooth structures of toothed bushes. Background technique [0002] The combination of toothed bushing and toothed screw pile is used for low-strength materials such as aluminum alloy to realize the installation of high-torque self-locking nuts. It is often used in the combined installation of aircraft engine structural parts. After the toothed screw pile is screwed into the base material and After the toothed bushing is assembled, the toothed bushing is vertically pressed into the base material and engages with the base material and the toothed stud to prevent the stud from rotating after the self-locking nut is installed. The installation diagram is shown in figure 1 . [0003] The structure diagram of the toothed bush is shown in Figure 2-4 As shown, the common materials are stainless steel and high-...
