Fixing device for precision casting grinding

Abstract

The invention relates to the technical field of precision castings, and discloses a fixing device for grinding precision castings, including a table, the upper right side of the table is rotatably connected to a transmission toothed plate, and the inner cavity of the transmission toothed plate is rotatably connected to the There is an adjustment plate, and a guide block is evenly arranged on the right side of the transmission toothed disc, and a block is slidably connected to the guide block, and a support plate is arranged on the upper end of the table and is located on the left side of the transmission toothed disc. The front part of the support plate is provided with a transmission gear rod, and the upper end of the table is fixedly installed on the right side of the transmission toothed plate with a second bracket, and the middle part of the second bracket is rotatably connected with a driving roller. The fixing device for grinding precision castings fixes the castings by rotating the adjusting disc to control the block, and cooperates with the transmission gear plate and the driving roller that can be controlled and connected by the transmission gear rod, so as to achieve fast and efficient fixing and lifting of the castings. The effect of casting grinding efficiency.

Description

technical field [0001] The invention relates to the technical field of precision castings, in particular to a fixing device for grinding precision castings. Background technique [0002] Castings are metal shaped objects obtained by various casting methods, and precision castings refer to the general term for the process of obtaining precise size castings. Compared with traditional sand casting processes, precision castings obtain castings with more accurate dimensions and better surface finish. It mainly includes: investment casting, ceramic casting, metal casting, pressure casting, lost foam casting. [0003] Precision castings need to be polished after casting to remove peripheral burrs. At present, when fixing tubular precision castings, it is difficult for some fixing devices to reliably fix the castings in a short time, resulting in Shaking may occur during the later grinding process. In addition, after the casting is fixed by the general fixing device, the grinding s...
