Engine shell inner curve grinding device

Abstract

The invention discloses an engine shell inner curve grinding device which comprises an operation table and a grinding machine body. Locking moving wheels are fixed to the four corners of the bottom of the operation table; a mounting plate is fixedly connected to the outer wall of the top of the operation table; a round opening is formed in the outer wall of one side of the mounting plate; the inner wall of the round opening is rotationally connected with a positioning shaft through a bearing; a driven gear is fixedly installed at one end of the positioning shaft; a motor is fixedly installed on the outer wall of one side of the mounting plate; a driving gear is installed on an output shaft of the motor; the driven gear is meshed with the driving gear; the other end of the positioning shaft is fixedly connected with a rotating plate; and the outer wall of the side, away from the positioning shaft, of the rotating plate is fixedly connected with an inserting shaft. According to the engine shell inner curve grinding device provided by the invention, the grinding machine body is driven by a mounting frame to move, and the moving track of the grinding machine body is a curve, so that curve grinding is conveniently achieved; and multi-specification curve grinding is conveniently achieved by adjusting the connecting position of the inserting shaft and a straight rod and adjusting the moving track of the grinding machine body.

Description

technical field [0001] The invention relates to the technical field of engine housing processing, in particular to a curve grinding device inside an engine housing. Background technique [0002] An engine is a machine that can convert other forms of energy into mechanical energy. It was first born in the UK. It is not only applicable to power generation devices, but also refers to the entire machine including power devices (such as: gasoline engines, aero engines). The types include, for example, internal combustion engines (gasoline engines, etc.), external combustion engines (Stirling engines, steam engines, etc.), electric motors, and the like. [0003] There is a curved surface inside the engine casing, in order to achieve smoothness inside the engine casing. In the prior art, it is often necessary to use a clamping device to clamp the engine casing in the production process, and then the motor drives the grinding head to grind the motor casing. At the same time, in ord...

Problems solved by technology

However, most of the grinding devices in the prior art are fixed on the console, therefore, the shape of the curved surface is relatively fixed, which is not easy to adapt to various types of engine casings.
