Clamping arrangement of guide block rough milling gap

Abstract

The invention relates to a guide block rough milling notch clamping device, which is characterized in that it includes an air valve control device, a pressurized oil cylinder, a working oil cylinder and a workpiece clamping mechanism; the air valve control device includes an air valve body and a handle switch Controlled air valve core; the booster oil cylinder is set on one side of the air valve control device. The booster oil cylinder includes a cylinder body and front and rear covers arranged at both ends of the cylinder body. An oil injection piston, an oil piston and a cylinder piston are arranged in the cylinder body. A high-pressure oil cylinder passing through the oil piston is arranged between the front cover and the oil injection piston, and the oil inlet joint of the working oil cylinder is connected to the oil outlet joint of the high-pressure oil cylinder through the oil pipe; A bolt rod is pierced on the force plate, the card body and the pressure plate, and a nut is connected outside the pressure plate, and one end of a slanted iron is inserted between the card body and the force plate, and the other end of the slanted iron is connected to the piston rod of the working cylinder . The invention has the advantages of simple structure and convenient operation, and can be used in the clamping processing of various workpieces.

Description

technical field [0001] The invention relates to a clamping device, in particular to a rough milling notch clamping device for an accessory guide block of a diesel locomotive. Background technique [0002] The guide block is an important part in the assembly of diesel engine push rods. The material is 42CrMo. The structure of the guide block is to open a gap with a height of 30 mm, a width of 11 mm and a depth of 52 mm at one end of a cylinder with a diameter of 59.5 mm. the ear pin holes in the center to fit the rollers here. Due to the high precision requirements for the notch of the guide block and the relatively hard material of the workpiece, the rough milling of the notch before the improvement has always been processed on an ordinary X63W milling machine, using special tooling for positioning, clamping with a pressure plate and a nut, and there is only one direction of clamping force. Due to the large cutting depth during guide block processing, the corresponding cut...
