Problems solved by technology

At present, the machining of the side hole of the camshaft usually adopts the method of positioning and clamping the outer circle of the small end of the camshaft and the movable pin. Due to the machining error of the outer circle of the small end and the certain tolerance of the movable pin, the accumulation of the two will It has a great impact on the machining accuracy of the side hole, and the efficiency of the above clamping method is also low, which is not suitable for mass production

Abstract

The invention discloses a camshaft side surface hole processing clamp; a positioning plate which forms an oblique angle Alpha with the bottom surface of a base is arranged above the base; the middle position of the positioning plate is provided with a positioning hole vertical to the positioning plate and a positioning pin which is arranged below the positioning hole; one side of the positioning plate is provided with a movable pressing plate and a pressing screw. Further improvement of the camshaft side surface hole processing clamp is characterized in that the movable pressing plate is a hook-shaped sliding pressing plate which is sheathed on the positioning plate; the positioning plate is provided with a drill sleeve which is arranged above the positioning hole. The camshaft side surface hole processing clamp is used for processing the side surface hole on the camshaft in a gasoline engine, has convenient assembly and disassembly and small positioning error, can improve the processing efficiency and processing precision and is suitable for batch production.

Description

technical field [0001] The invention relates to a drilling fixture, in particular to a camshaft side hole machining fixture. Background technique [0002] The camshaft is an important part of a general-purpose gasoline engine. The side hole of the camshaft has an inclination angle α with the camshaft axis, and has a center distance requirement from the gear end face at one end of the camshaft. It is difficult to process and must be accurately positioned and reliably pressed. At present, the machining of the side hole of the camshaft usually adopts the method of positioning and clamping the outer circle of the small end of the camshaft and the movable pin. Due to the machining error of the outer circle of the small end and the certain tolerance of the movable pin, the accumulation of the two will It has a great impact on the machining accuracy of the side hole, and the efficiency of the above clamping method is also low, which is not suitable for mass production.
