Locking shaft square milling device

Abstract

The invention provides a locking shaft square milling device. The device comprises a horizontal lathe, a milling cutter, a cutting fluid pipe and a locking shaft clamping assembly. The locking shaft clamping assembly comprises a sleeve pipe, a puller screw, a nut and a fixed base, the sleeve pipe is vertically arranged, an inner hole of the sleeve pipe is matched with a locking shaft, the nut is fixedly connected to the side wall of the sleeve pipe, the puller screw is matched with the nut and penetrates through the side wall of the sleeve pipe to extend into the inner hole of the sleeve pipe,and the sleeve pipe is fixedly connected with the side wall of the fixed base. The fixed base of the locking shaft clamping assembly is clamped and fixed on a tool rest of the horizontal lathe, and the milling cutter is clamped on a chuck of the horizontal lathe. One end of the cutting fluid pipe communicates with a cutting fluid source, and the other end of the cutting fluid pipe is aligned to the milling position of the milling cutter below the sleeve pipe. The locking shaft square milling device has the beneficial technical effects that a method is quick to operate, precision is high, multi-edge locking shaft manufacturing is met, the production efficiency is greatly improved during use, the labor cost is reduced, and the surface smoothness, the basic size and the tolerance of a machined part meet the drawing design requirement.

Description

technical field [0001] The invention relates to a square milling device for a locking shaft. Background technique [0002] The locking shaft is a component commonly used in civil air defense facilities, such as figure 1 As shown, the locking shaft 1 includes a head 11, a shaft body 12, a square portion 13 and a threaded section 14. When processing the square portion 13 of the locking shaft 1, the lower part of the shaft body 12 whose cross-sectional shape is originally circular needs to be processed as The square part 13 with a square cross section is usually processed by a milling machine in the prior art, but the milling process has the following disadvantages: 1. Difficult positioning; 2. Low production efficiency; 3. High labor cost. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a square milling device for locking shafts with reasonable structure and high processing efficiency. [0004] In order to solve ...
