Description

Workpiece fixing device for shot blasting trolley and using method thereof Technical Field The invention relates to the technical field of casting process equipment, in particular to a workpiece fixing device for a shot blasting trolley and a use method thereof, which are particularly suitable for supporting, positioning and protecting a workpiece in a movable trolley type shot blasting machine. Background In the trolley operation process of the shot blasting machine for casting, the arrangement mode of the workpieces directly influences the cleaning effect and the production efficiency. In actual production, the sizes of part of workpieces exceed the conventional range, and the placing positions and angles are required to be adjusted according to the characteristics of the cavities of the workpieces so as to ensure the comprehensiveness and efficiency of shot blasting. In addition, when the production rhythm is tense, the number of the workpieces to be placed on the trolley is often required to be increased, so that the single processing capacity is improved. At present, the conventional practice is to use the scattered cast iron parts to carry out the bed hedgehopping, because the characteristics of throwing the ball operation, the platform truck is cast iron screen cloth, but after long-term use, cast iron screen cloth plane is not level after being thrown the ball impact, on unavoidable existence shot cleaning up not clean the condition, consequently the cushion is placed and is required to waste time and energy the clearance, and because of unable assurance clearance effect leads to the cushion to place the stability poor, has brought very big potential safety hazard. Meanwhile, the table top of the trolley is a cast iron screen mesh, a permanent supporting piece cannot be welded, and the exposed surface entering the chamber body faces high-strength impact of shot blasting due to the operation characteristics of shot blasting equipment, so that long-term use cannot be maintained, and the disassembly after abrasion is very inconvenient.
