Description

Sand blasting, force unloading and deformation preventing tool for weak products Technical Field The utility model relates to the technical field of sand blasting clamps, in particular to a weak product sand blasting force unloading anti-deformation tool. Background Sand blasting is a surface treatment process that uses compressed air or centrifugal force to spray abrasive materials (e.g., steel grit, glass beads, ceramic particles, etc.) at high speed onto the surface of a workpiece for rust removal, deburring, cleaning, or roughness enhancement. Its functions include improving adhesion of coating, improving surface appearance and strengthening metal parts. The technological parameters (pressure, angle and abrasive type) directly influence the treatment effect, and the method is suitable for various materials such as metal, plastic, glass and the like. In conventional blasting operations, operators place the product to be treated directly on a work surface, and blasting is performed by using fixed pressure parameters. After the sand blasting is finished, the product enters a detection station for size measurement, and the next procedure is carried out if the product meets the requirements. For thin-wall parts or precision parts, the process adopts a standard supporting mode, and uses conventional metal abrasive materials to complete the whole sand blasting process according to a general operation instruction. The conventional sand blasting method is easy to cause plastic deformation of the product, particularly obvious dimensional deviation can occur at the weak part of the structure, and in order to meet the drawing requirement, the subsequent shaping process is required to be added for manual correction, so that the production period is prolonged, the manufacturing cost and the secondary damage risk are increased, the deformation problem becomes a key bottleneck affecting the production efficiency and the product quality, and therefore, the weak product sand blasting force unloading deformation preventing tool is provided to solve the problems. Disclosure of utility model In order to make up for the defects, the utility model provides a weak product sand blasting force unloading deformation prevention tool, and aims to solve the problems that in the prior art, plastic deformation of a product is easy to occur, and particularly obvious dimensional deviation can occur at a weak part of a structure. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The utility model provides a weak product sandblast unloads power preapring for an unfavorable turn of events shape frock, includes the bottom plate, the top of bottom plate is installed the extension spring and is gone down the fixed plate, the top fixedly connected with a plurality of extension spring bodies of fixed plate under the extension spring, the other end fixedly connected with extension spring upper fixed plate of extension spring body, the top fixedly connected with main part support frame of extension spring upper fixed plate, fixed buckle is installed to the inner wall of main part support frame, side location dog is installed to the inner wall of main part support frame, the top threaded connection of main part support frame has the hand to twist the screw, the bottom of hand to twist the screw rotates and is connected with the buckle reinforcing plate, the bottom fixedly connected with activity buckle of buckle reinforcing plate, the product is installed with the close one side of activity buckle to the fixed buckle, the top both sides of buckle reinforcing plate are all fixedly connected with restriction subassembly; As a further description of the above technical solution: One side of the main body support bracket is fixedly connected with a strength reinforcing rib, and one side of the lateral positioning stop block is contacted with one side of the product; As a further description of the above technical solution: the two sides of the top of the buckle reinforcing plate are fixedly connected with a stopper screw, the outer part of the stopper screw is connected with the inner wall of the main body supporting bracket in a sliding manner, and a return spring is sleeved outside the stopper screw; As a further description of the above technical solution: One end of the return spring is fixedly connected to one side of the main body support bracket, and the other end of the return spring is fixedly connected to one side of the stopper screw.
