Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a shot blasting machine with a conveniently adjustable clamp. Background Art

[0002] Shot blasting machine is a casting equipment that uses a shot blaster to throw steel grit and steel shot at high speed onto the surface of the workpiece to be processed, thereby cleaning and strengthening the surface of the workpiece. Shot blasting can change the outer surface of the workpiece due to the impact and cutting action of the abrasive, obtain a certain degree of cleanliness and different degrees of roughness, and improve the mechanical properties of the workpiece surface. When the shot blasting machine processes the workpiece, it is necessary to clamp and fix the workpieces of different models through a fixture to facilitate the equipment to process.

[0003] For example, a Chinese utility model patent with authorization announcement number CN218927460U discloses a convenient-to-operate turntable shot blasting machine, which relates to the technical field of shot blasting machines, including a shot blasting machine production line housing, a shot blasting area is arranged inside the shot blasting machine production line housing, and a processing device is fixedly installed inside the shot blasting machine production line housing, the processing device includes a processing table, a double-axis motor, a forward screw, a reverse screw, a fixture, a mounting block, a rotating disk, a support seat, a rotating motor and a roller. When the workpiece is shot blasted, the double-axis motor runs, and the two mounting blocks are movably adjusted on the forward screw and the reverse screw to a width suitable for the workpiece, and the two ends of the workpiece are clamped and fixed with a fixture. The shot blasting equipment performs shot blasting on the workpiece, and the roller can be driven to rotate by the motor, so that the workpiece clamped on the fixture can rotate with the rotation of the connecting shaft, so as to achieve the purpose of processing multiple reference surfaces of the workpiece.

[0004] However, in the existing shot blasting machine with an easy-to-adjust clamp, the mounting block slides inside the rectangular groove when clamping and fixing the workpiece during use, and the rectangular groove is exposed on the surface.
