Rounding device

Abstract

The invention discloses a rounding device comprising a support frame. A first drive motor is arranged on the top of the support frame, a fixing plate is arranged at one end of the support frame, a connecting rod is arranged at the bottom of the fixing plate, the bottom end of the connecting rod is provided with a limiting ball, a first sliding slot is arranged at the connection position of the support frame and the connecting rod, a second sliding slot is arranged at the connection position of the support frame and a limiting ball, a fixing bolt is arranged between the fixing plate and the support frame, a limiting groove is arranged at the connection position of the fixing plate and the fixing bolt, a reset spring is arranged between the inner wall of the limiting groove and the fixing bolt, and a second drive motor is arranged on the top of the fixing plate. The rounding device is provided with the fixing plate and the connecting rod, a grinding disc is in contact with the inner wallof a cylinder sleeve to drive the fixing plate to move to the rear portion, the resilience force action of the reset spring can drive the connecting rod to do reciprocated sliding inside the first sliding slot and the limiting ball to do reciprocated sliding in the second sliding slot, and damage caused by the fact that protrusion positions cannot be polished at a time to the polishing disc is avoided.

Description

technical field [0001] The invention relates to the field of grinding devices, in particular to a rounding device. Background technique [0002] At present, during the repair process of diesel engine cylinder liners on many domestic ships, the problem of ellipticity of the cylinder liner will be encountered. The ellipse is mainly caused by the movement of the piston in the cylinder liner, including normal wear and abnormal wear. If its wear is still within the limit range of use, of course it must be repaired, because the cost of the cylinder liner is relatively high, especially for foreign diesel engines, the price is very expensive when using foreign cylinder liners. The current repair method is basically to hang the cylinder liner from the body of the diesel engine, and then take it to the workshop for repair, such as turning on a lathe, boring on a boring machine, etc. Although this repair method is good, it needs to spend a lot of money. Human and material resources. ...

AI Technical Summary

Problems solved by technology

The existing rounding device is too complicated to adjust the scale during use, and if the adjustment scale is not accurate enough, it is easy to cause excessive grinding of the grinding position or damage caused by direct contact between the milling cutter, the grinding head and the repair position, thus failing to achieve normal The effect of using
