TECHNICAL FIELD
[0001] The utility model relates to the technical field of machining auxiliary equipment, especially a novel fixed tooling matched with shot blasting equipment. BACKGROUND
[0002] In the industrial production field, shot blasting equipment (shot blasting machine) is often used to perform shot blasting on corresponding parts (high-speed shot blasting is used to impact the surface of the workpiece to improve the mechanical properties of the parts and change the surface state). Due to different equipment to be processed and the material of the equipment (for example, due to changes in the processed parts), different processing technologies, and other factors, the shot blasting equipment uses different projectile materials when performing shot blasting on different equipment workpieces, which may be cast iron shots, ceramic shots, or sand shots, and the outer diameters of the projectiles of different materials are not the same.
[0003] The existing shot blasting equipment generally includes a rack, a motor speed reduction mechanism, and a fixed tooling. Specifically, multiple fixed toolings are rotatably installed on the outer side ends of the rack at annular intervals. Before shot blasting, multiple workpieces (such as gears) that need to be shot blasted are placed in the fixed discs on the upper ends of the multiple fixed toolings. The driving pulley of the motor speed reduction mechanism drives the multiple fixed toolings below through a ring-shaped synchronous belt to rotate synchronously, and the multiple fixed toolings and the workpieces above them rotate. Multiple nozzles of the shot blasting equipment on the periphery of the rack synchronously spray shots to perform shot blasting on the rotating workpieces (in some shot blasting equipment, the motor speed reduction mechanism, the rack, and the multiple fixed toolings are driven to rotate by another motor speed reduction mechanism, and the multiple rotating fixed toolings are sequentially rotated under a nozzle to perform shot blasting). Although the existing shot blasting equipment meets the needs of workpiece shot blasting to some extent, it still has some technical problems due to its structure. First, after the workpieces are placed in the fixed discs of the fixed toolings, there is no fixing mechanism, so the workpieces will move during rotation under the action of centrifugal force and other factors. This will affect the effective shot blasting of the workpiece surface due to the unstable position of the nozzle lower end, and the workpieces will also shake in the fixed discs during rotation, which will cause the entire equipment to run unstably. Second, some of the shots used in shot blasting will splash out of the fixed discs after processing the workpieces, and some will accumulate on the side end of the workpiece in the fixed disc, which will adversely affect the subsequent cleaning work of the staff, and the shots accumulated on the side end of the workpiece will block the shots sprayed by the nozzle, which will prevent the corresponding position of the workpiece from being effectively shot blasted. In summary, it is necessary to provide a fixed tooling that can effectively fix the shot blasted workpieces, reduce the shots sprayed out of the fixed disc, and reduce the adverse effects on the shot blasting of the workpieces. SUMMARY
