Description

Technical Field

[0001] The utility model relates to the technical field of automobile valve body shot blasting, in particular to a surface shot blasting device for automobile valve bodies. Background Art

[0002] The automotive valve body is a key component in the vehicle engine, used to control the flow of fluids such as fuel, air, and exhaust gases. Its performance directly impacts the engine's efficiency, power output, and emissions. During valve body processing, shot blasting is typically performed on the valve body to remove impurities such as dirt, oxide layers, and rust layers from the valve body surface and to improve its surface cleanliness and roughness. A shot blasting device is a mechanical device that uses a high-speed rotating impeller to accelerate projectiles to a high velocity, causing them to impact the workpiece surface, thereby changing its appearance or shape. Shot blasting ensures the cleanliness and uniformity of the valve body surface, improving its overall quality and performance. Surface strengthening also enhances the valve body's wear resistance and fatigue resistance, extending its service life.

[0003] At present, most of the shot blasting devices for valve surface treatment on the market are very inconvenient to use. Not only is the efficiency low during shot blasting, but it is also difficult to remove the valve from the device after shot blasting, which affects the production efficiency of the valve. In addition, dust or foreign matter is easily adhered to the valve surface after shot blasting, and manual cleaning is required. This process increases the burden on workers. For example, the patent document with announcement number CN215394656U discloses a shot blasting device for valve surface treatment, which uses a cylinder to remove the treated treatment box from the shot blasting box, and then turns on the fan to drive air into the air inlet pipe through the fan, and sprays it out from the nozzle on the side of the exhaust pipe, thereby removing dust or foreign matter from the valve surface, achieving the effect of eliminating the need for manual cleaning and reducing the burden on workers.

[0004] Although the dust or foreign matter on the valve surface can be removed by the action of the fan, in the prior art, when the automobile valve body is shot blasted by a shot blasting device, the shots are generally directly put into the feed port and ejected through the shot blaster to achieve shot blasting. Since the amount of shot feed cannot be well adjusted and controlled, the surface quality problems of the automobile valve body caused by excessive or insufficient shots cannot be well avoided, which is not conducive to improving the flexibility of feeding and ensuring the quality of automobile valve body treatment. Therefore, in order to solve the above problems, a surface shot blasting device for automobile valve body is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a surface shot blasting device for automobile valve bodies, so as to solve the problem mentioned in the above background technology that the amount of shot feed cannot be well adjusted and controlled, making it impossible to well avoid the surface quality problem of automobile valve bodies caused by excessive or insufficient shots, thereby being detrimental to improving the flexibility of feeding and ensuring the quality of automobile valve body processing.

[0012] Preferably, the rotating rod is fixedly connected to the output end of the second motor, and the two ends of the connecting rod are respectively connected to the rotating rod and the connecting plate, and the connecting plates are movable in five groups on the inner side of the feed hopper.
