Description

Technical Field

[0001] The utility model relates to the technical field of shot blasting machines, in particular to a special hanger for shot blasting of a flywheel housing of an automobile. Background Art

[0002] Shot blasting is the name of a mechanical surface treatment process. The traditional shot blasting hanger has a complex structure, and the welding end of the hook has no reinforcement structure. The hook is easily deformed under the gravity of the workpiece, which seriously causes the hook to fall off from the welding end, making the work unstable. Once the hanger is hung with shot blasting, it is difficult to move and can only be moved by hook. This new hanger solves the problems of difficult hanger movement, easy deformation and space occupation.

[0003] According to application number 201921464700.0, a special hanger for shot blasting of automobile flywheel housing includes a main rod, an upper plate is welded on the top of the main rod, and a hook is welded on the top of the upper plate, a first sliding key and a second sliding key are sequentially sleeved on the outer wall of the main rod from bottom to top, a mounting hole is opened on the outer wall of one side of the main rod, a spring key is slidably connected inside the mounting hole, a first short rod equidistantly distributed is rotatably connected to the circumferential outer wall of the first sliding key, and a second short rod equidistantly distributed is rotatably connected to the circumferential outer wall of the second sliding key, long rods equidistantly distributed are hinged on the circumferential outer wall of the upper plate, a third short rod is hinged in the middle of the long rod, and a hanging rod is welded on the outside of the long rod at equal distances.

[0004] The device has a simple structure, is easy to store, and has a certain structural strength. When the first sliding key is pushed to prop up the hanger, it is placed on the ground and can be moved through the universal wheel. There is a shock-absorbing spring on the top of the universal wheel, which can effectively reduce the shaking of the shot blasting during the movement. However, the distance between the hooks of the device cannot be adjusted, which causes the large-sized flywheel shell to be damaged by collision. Utility Model Content
