Description

Technical Field

[0001] The invention relates to the technical field of shot blasting machines, in particular to a hook-type shot blasting machine for eliminating shot blasting dead angles. Background Art

[0002] Hook-type shot blasting machines are widely used in the surface cleaning or strengthening of medium and small castings and forgings in the casting, construction, chemical, motor, machine tool and other industries. For some special-shaped workpieces such as crankshafts, a carrier is required to load the special-shaped workpiece into the shot blasting cleaning room, and then the shot blaster is used to throw 0.2-0.8mm projectiles onto the surface of the workpiece, so that the surface of the workpiece reaches a certain roughness, making the workpiece beautiful, or changing the compressive stress of the workpiece to increase its service life;

[0003] After checking the publication number: CN218226171U, a hook-type shot blasting cleaning machine is disclosed. This technology discloses "a hook-type shot blasting cleaning machine, which relates to the technical field of shot blasting machines, specifically a hook-type shot blasting cleaning machine, including a shot blasting cleaning chamber, a hoist, a separator, and a shot blaster. The front and rear sides of the shot blasting cleaning chamber are provided with inlets and outlets. A walking guide rail is fixedly installed on the top of the shot blasting cleaning chamber, and a guide chain is clamped inside the walking guide rail. A hollow gear is movably sleeved on the top of the guide chain. A threaded rod is sleeved on the internal thread of the hollow gear. A servo motor is fixedly connected to the top of the guide chain" and other technical solutions, which have "by arranging inlets and outlets on the front and rear sides of the shot blasting cleaning chamber, feeding and discharging can be performed at the front and rear inlets and outlets of the shot blasting cleaning chamber at the same time, and feeding and discharging are performed synchronously without affecting each other, thereby improving the cleaning efficiency. By installing two hooks on one guide chain, the two hooks can move synchronously, with a high coordination rate and time saving" and other technical effects;

[0004] When a conventional hook-type shot blasting machine is in use, the workpiece is hung on the hook and the workpiece is rotated by rotating the hoisting mechanism, thereby ensuring that the entire surface can be evenly treated; however, when multiple workpieces are hung on the hook, the hoisting mechanism can only drive multiple workpieces to revolve when it rotates, which may cause the workpieces to block each other, resulting in the shot blasting being unable to evenly act on all surfaces of each workpiece. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a hook-type shot blasting machine for eliminating blind spots in shot blasting, which has the characteristics that the workpieces suspended on each hanging mechanism can rotate simultaneously during the revolution, so as to ensure that the surface of the workpieces inside the cleaning chamber can be evenly processed by the shot blasting machine.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions: A hook-type shot blasting machine for eliminating shot blasting dead angles, including a shot blasting machine and used for surface treatment of a workpiece, a suspension assembly is provided on the shot blasting machine and used for controlling the movement of the workpiece, and the suspension assembly includes:
