Positioning device for machining cam shaft and cam by milling machine

Abstract

The invention discloses a positioning device for machining a cam shaft and a cam by a milling machine. The positioning device comprises a fixing table, two fixing columns are welded at the bottom of the fixing table, two positioning device bodies are symmetrically arranged at the top of the fixing table, grooves are formed in the sides, close to each other, of the two positioning device bodies, positioning rods are installed in the grooves in a sliding mode, one ends of the positioning rods extend out of the grooves, and positioning clamping blocks are welded to the ends, close to each other,of the two positioning rods; and first rotating shaft grooves are formed in the ends, located in the grooves, of the positioning rods, first rotating shafts are rotationally installed in the first rotating shaft grooves, one ends of the first rotating shafts extend out of the first rotating shaft grooves, second rotating shaft grooves are formed in the inner walls of the sides, far away from the positioning rods, of the grooves, and the second rotating shaft grooves are rotationally connected with the first rotating shafts. According to the positioning device, the structure is simple, the useis convenient, through the positioning device bodies, the positioning work can be more conveniently carried out, moreover, connecting rods can be easier to fix, the operation is easy, the time is saved, and the use by people can be facilitated to a greater degree.

Description

[0003] The patent application number is 201720031798.5. The invention patent discloses a special milling machine for brake camshafts. It includes a machine tool body, a fixture and a tool that are located opposite to the machine tool body. device, the positioning device includes a support arm perpendicular to the side wall, and a piston pushing device on the support arm. The piston rod of the piston pushing device is connected with a conflicting component, and the conflicting component includes a Positioning rod, the measuring stud positioned at one end of the positioning rod, but the positioning device used by the existing milling machine to process the camshaft cam is relatively troublesome when performing positioning work, and it is not easy to fix, delays time, and is not conducive to people's use. With the advancement of technology and the development of society, people have put forward higher requirements for the positioning device of milling machines. Therefore, we have proposed a positioning device for milling machines to process camshafts and cams to solve the above problems.
