Description

Technical Field

[0001] The utility model relates to the field of casting processing, in particular to a positioning device for precision casting processing. Background Art

[0002] Castings are metal formed objects obtained by various casting methods, that is, the smelted liquid metal is injected into a pre-prepared mold by pouring, injection, suction or other casting methods. After cooling, through subsequent processing means such as grinding, an object with a certain shape, size and performance is obtained. There are various classification methods for castings: according to the different metal materials used, they are divided into steel castings and iron castings. According to the different mold forming methods, castings can be divided into ordinary sand mold castings, metal mold castings, etc.

[0003] During the processing of castings, to ensure the safety of the castings, they need to be firmly positioned. However, after the existing castings are positioned, their positions are fixed. When different positions of the castings need to be processed, they still need to be disassembled and adjusted again, which is not convenient to adjust the fixed position according to the processing requirements at any time, reducing the use effect. For this reason, we propose a positioning device for precision casting processing to solve the above problems. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a positioning device for precision casting processing to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

A sliding round table is slidably connected inside the circular slide rail. A rack ring is fixedly connected to the inner wall of the sliding round table. The upper surface of the processing platform is fixedly connected with a reduction motor. The output end of the reduction motor is fixedly connected with a driving gear, and the driving gear meshes with the rack ring. A placement table is fixedly connected to the upper surface of the sliding round table. Two protective baffles are fixedly connected to the upper surface of the placement table.
