Clamp special for drilling, milling and cutting carbon fiber composite material

Abstract

The invention relates to a clamp special for drilling, milling and cutting a carbon fiber composite material and belongs to the field of mechanical machining clamps. The clamp consists of three portions including a cutting angle adjusting device, a plate length adjusting device and a plate thickness adjusting device. In the cutting angle adjusting device, an adapter plate is installed on an angle-adjustable worktable through a T-shaped bolt, a hand wheel is installed on the angle-adjustable worktable, an inclination angle of a worktable top is adjusted by turning the hand wheel so as to complete cutting at different machining angles. The plate length adjusting device is composed of a left slide block, a right slide block and a sliding rail. In the plate thickness adjusting device, a left clamp body and a right clamp body are respectively installed on the left slide block and the right slide block through bolts. A left press plate and a right press plate are respectively installed on the left clamp body and the right clamp body through bolts. By means of the special clamp, an edge milling or grooving experiment of four edges of a sample piece to be experimented can be completed through one-time clamping. The clamp is simple in structure and good in flexibility, and the experiment accuracy and experiment efficiency are improved.

Description

technical field [0001] The invention belongs to the field of machining fixtures, and relates to a special fixture for drilling and milling carbon fiber composite materials. Background technique [0002] Carbon fiber composite materials have the characteristics of high strength, fatigue resistance, and corrosion resistance. They can effectively reduce the weight of aircraft and improve the structural efficiency of aircraft, so they are widely used in the aerospace field. Carbon fiber composite materials are difficult-to-process materials, which present a mixed form of fibers and resins on the microscopic scale, anisotropy and lamination characteristics on the macroscopic scale, and are prone to processing damage such as delamination, tearing, and burrs during processing, as well as tool wear This phenomenon seriously restricts the high-quality and efficient machining of aircraft components. Therefore, in view of the problems existing in the processing of carbon fiber composi...

AI Technical Summary

Problems solved by technology

However, there is no special fixture for carbon fiber composite materials in the experiment, and the drilling and milling experiments cannot be completed on one set of equipment, and the functional requirements for milling of the four sides of the rectangular sample can be completed under one clamping. The experimental accuracy and experimental efficiency Low
