Technical Field

[0001] The utility model relates to the field of fixing a cylindrical workpiece of a shot blasting machine, in particular to a pipe supporting tool for a shot blasting machine. Background Art

[0002] Shot blasting machine is a processing technology that uses a shot blaster to throw steel sand and steel shot at high speed to impact the surface of the material object. Compared with other surface treatment technologies, it is faster and more effective, and can be used for partially retained or stamped casting processes. Among the workpieces processed by the shot blasting machine, there is a cylindrical workpiece with upper and lower openings. At present, before the cylindrical workpiece is shot blasted, the cylindrical workpiece is usually clamped and fixed. This fixing method is easy to cause damage to the cylindrical workpiece, and the clamping part will be blocked, resulting in incomplete shot blasting. The Chinese utility model patent with application number 201922016182.2 discloses a pipe support fixture for a shot blasting machine, which solves the problem that the existing shot blasting machine polishes the pipe fittings, and the existing clamps polish the workpiece so that the clamped part cannot be polished, thereby affecting the polishing effect of the pipe fittings.
