Description

Technical Field

[0001] The utility model relates to the technical field of machining, in particular to a shot blasting treatment device for a motorcycle engine housing. Background Art

[0002] After the rough machining of the motorcycle engine housing is completed, metal chips are likely to adhere to the surface of the housing, and internal stress is also likely to remain in the housing. Therefore, the housing is generally subjected to shot blasting treatment to clean the surface, increase adhesion, eliminate internal stress, and improve service life, etc.

[0003] When shot blasting the motorcycle engine housing, a hook type shot blasting machine is mostly used for shot blasting the housing. When transferring the housing into the shot blasting machine, several housings are generally placed in the shot blasting machine in a batch manner for shot blasting treatment. When changing the processing batch of the housing, the shot blasting machine needs to be paused, and after changing the processing batch of the housing, the shot blasting machine is started again. The shot blasting machine will reduce the number of shot blasted housings during the shutdown and other feeding idle periods, and will reduce the shot blasting treatment efficiency of the housing. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the utility model provides a shot blasting treatment device for a motorcycle engine housing to solve the problem that when changing the processing batch of the housing, the shot blasting machine will reduce the number of shot blasted housings during the shutdown and other feeding idle periods, and will reduce the shot blasting treatment efficiency of the housing.

[0005] To achieve the above purpose, the basic scheme of the utility model is as follows: A shot blasting treatment device for a motorcycle engine housing, including a shot blasting chamber and a shot blasting unit located inside the shot blasting chamber. The shot blasting chamber is provided with a feeding port, and further includes:

[0006] A conveyor belt, which is horizontally arranged inside the shot blasting chamber. The rotation axis of the conveyor belt is perpendicular to the ground. The side wall of the conveyor belt faces the shot blasting unit, and the end of the conveyor belt is located outside the feeding port.

[0007] A hoisting member detachably connected to the housing, and the hoisting member is detachably connected to the side wall of the conveyor belt close to the shot blasting unit.

[0008] A baffle plate, which can cover the feeding port of the shot blasting chamber.

[0009] The technical principle of the present utility model is as follows: When performing shot peening treatment on the housing, the conveyor belt can cooperate with the lifting member to continuously convey the housing to be shot peened, so that the housing is shot peened by the shot peening unit during the conveying process; when the lifting member drives the shot peened housing to move to the discharge port, the shot peened housing can be removed at this time. After installing the housing to be shot peened on the lifting member, the conveyor belt continuously conveys the housing to be shot peened for shot peening treatment, enabling the shot peening unit to continuously perform shot peening treatment on the housing and improving the shot peening efficiency of the housing.

[0010] Meanwhile, during this process, the baffle can cooperate with the rotation of the conveyor belt to drive the housing. When the housing moves to the discharge port, the baffle opens the feed port of the shot peening chamber to facilitate the housing to enter and exit the feed port of the shot peening chamber; when the housing does not move to the discharge port, the baffle seals the feed port of the shot peening chamber to prevent the shot from splashing out from the feed port.

[0011] Furthermore, several threaded cylinders are fixedly installed by embedding on the side wall of the conveyor belt close to the shot peening unit. The threaded cylinders are detachably connected to the lifting member, and the axis of the threaded cylinder is parallel to the rotation axis of the conveyor belt.

[0012] Through the above settings, the threaded cylinders are more convenient for detachable connection with the lifting member. At the same time, the threaded cylinders are also more convenient for being stably installed on the conveyor belt, and the position of the threaded cylinders is also more convenient for the lifting member after installation to be opposite to the shot peening unit, realizing accurate shot peening treatment.

[0013] Furthermore, the lifting member is in an "L" shape. An external thread that is threadedly connected to the threaded cylinder is provided at the upper end of the lifting member, and a vertically upward limiting protruding rod is fixedly provided at one end of the lifting member away from the external thread.

[0014] Through the above settings, the limiting protruding rod can cooperate with the "L"-shaped lifting member to realize accurate positioning of the hung housing and improve the stability of hanging the housing.

[0015] Furthermore, the end of the limiting protruding rod away from the lifting member is in a frustum shape.

[0016] Through the above settings, when the end of the limiting protruding rod abuts against or slides across the surface of the housing, being in a frustum shape can more smoothly slide across the surface of the housing, reducing the probability of scratching the end of the limiting protruding rod and the housing.

[0017] Furthermore, an intermittent lifting unit is provided between the baffle and the shot peening chamber. The intermittent lifting unit includes:

[0018] A slide rail, which is vertically and fixedly installed on the outer wall of the shot peening chamber and is located on the side of the feed port of the shot peening chamber;

[0019] The electromagnetic slider is slidably controlled and installed on the slide rail. The surface of the baffle is fixedly connected to the electromagnetic slider, and the side of the baffle can abut against the side wall of the conveyor belt near the shot blasting unit.

[0020] Through the above settings, it is more convenient to control the position of the baffle through the electromagnetic slider, facilitate the control of the coincidence state between the baffle and the feed port, facilitate the shell to enter and exit from the material port, and also reduce the ejection amount of the shot.

[0021] Furthermore, an embedding groove for the slide rail to be embedded and installed is provided on the outer wall of the shot blasting box, and one side of the baffle close to the electromagnetic slider fits against the outer wall of the shot blasting box.

[0022] Through the above settings, the stability of the installation of the slide rail is improved. At the same time, it is also convenient for the side wall of the baffle to fit against the outer wall of the shot blasting box, and the stability of the up and down movement of the baffle is improved.

[0023] Furthermore, it also includes a power unit, and the power unit includes:

[0024] A gear that meshes with the inner wall of the conveyor belt;

[0025] A motor that drives the gear to rotate, and the motor is fixedly installed on the shot blasting box.

[0026] Through the above settings, the gear can stably mesh with the inner wall of the conveyor belt, and the stability of the circumferential rotation of the conveyor belt is improved.

[0027] Furthermore, the threaded cylinder is opposite to the tooth groove of the gear.

[0028] Through the above settings, the threaded cylinder can be more stably installed at the teeth of the inner wall of the conveyor belt. The thickness of the conveyor belt here is relatively large, which can improve the installation strength of the threaded cylinder. Description of the Drawings
