A casting gate grinding device

Abstract

The invention provides a casting gate grinding device, which relates to the technical field of casting grinding. The casting gate grinding device includes a frame body, a limit sleeve is fixedly installed on the top inside the frame body, and a worm is connected to the inside of the limit sleeve through a bearing for rotation, and a knob is fixedly installed on the top end of the worm , the periphery of the worm is sleeved with a threaded sleeve, the bottom end of the threaded sleeve is fixedly connected with a spring, the bottom end of the spring is fixedly connected with a connecting block, and the connecting block is fixedly installed on the periphery of the installation sleeve, so The above-mentioned installation sleeve is located in the guide rail grooves opened on both sides of the limit sleeve. The casting gate grinding device can grind the gate to the same arc surface as the casting module, which improves the quality of grinding, thereby improving the surface accuracy of castings, and can adjust the processing efficiency of grinding and choose a reasonable The grinding disc improves the practicability of the grinding device.

Description

technical field [0001] The invention relates to the technical field of casting grinding, in particular to a casting gate grinding device. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, including steel castings, iron castings, copper castings, aluminum castings, etc. Castings are smelted liquid metals that are cast, injected, inhaled or otherwise cast The method is to inject into the pre-prepared mold, and after cooling, the obtained object has a certain shape, size and performance. [0003] However, due to the casting method, in order to allow the liquid metal to enter the cavity, an ingate is required, and after the casting is cooled and formed, a gate will be attached to the periphery, but the grinding of the traditional gate grinding device The cutting plane is kept level with the gate surface, and it can only grind the castings with a flat gate attachment surface, but when the gate is attached to the arc surface of t...

Problems solved by technology

[0003] However, due to the casting method, in order to allow the liquid metal to enter the cavity, an ingate is required, and after the casting is cooled and formed, a gate will be attached to the periphery, but the grinding of the traditional gate grinding device The cutting plane is kept level with the gate surface, and it can only grind the castings with a flat gate attachment surface, but when the gate is attached to the arc surface of the casting, such as the side of the cylinder, the spherical surface, etc. , the traditional gate grinding device cannot grind the standard arc surface, and the grinding effect is reduced
