[0004] The above-mentioned device can grind belt pulleys of different sizes through the cooperation of structures such as arc-shaped plates, grooves, threaded rods, and sliders. However, this structure does not construct an automated grinding structure, still requires a lot of manual cooperation, and cannot perform integrated grinding on multiple groups of belt pulleys. It has a low degree of automation and a high demand for labor costs. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a belt pulley grinding device, which solves the problems of low automation degree and high investment in labor costs existing nowadays.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A belt pulley grinding device includes a device main body, a control panel, and a second motor. The control panel is arranged on the front surface of the device main body, and the second motor is arranged inside the device main body;

[0007] A grinding disc is arranged on one side inside the device main body. A turntable is arranged on the outside of the grinding disc. A belt pulley is arranged on the outer end face of the turntable;

[0008] The grinding disc further includes a coupling gear, a driving gear, and a connecting shaft. The coupling gear is welded to the side end of the grinding disc. The tooth grooves of the driving gear are meshed with the coupling gear. The connecting shaft is movably connected to the middle of the rear end of the driving gear.

[0009] As a preferred technical solution of the present utility model, the other end face of the connecting shaft extends towards the direction of the second motor and passes through the interior of the equipment main body to establish a movable connection relationship with the second motor.

[0010] As a preferred technical solution of the present utility model, the equipment main body further includes a first motor and a cleaning brush. The first motor is fixedly installed in the inner wall of the equipment main body and extends outward. The cleaning brush is fixedly connected to the inner bottom of the equipment main body by adhesion.

It is made of a colloidal material as a whole, has high flexibility, and strip-shaped structures extending outward are arranged on the arc surface of its upper surface.

[0012] As a preferred technical solution of the present utility model, the first motor is movably connected to the rear end of the turntable, and a shaft seat structure is arranged at the connection position.

[0013] As a preferred technical solution of the present utility model, eight sets of shaft structures extending outward are arranged at one end of the turntable facing the outside, and there is a movable connection relationship between the shaft structures and the pulley.

[0015] Compared with the prior art, the present utility model provides a pulley grinding device, which has the following beneficial effects:

[0016] This pulley grinding device, by setting a turntable, a grinding disc, a cooperating gear, a driving gear, and a cleaning brush, when the device performs pulley grinding operations, the operator can install up to eight groups of pulleys on the shafts on the outer peripheral end face of the turntable, and then control the first motor and the second motor through the control panel. After the first motor and the second motor are started, the first motor drives the turntable to rotate. At this time, the pulleys fixedly connected to the front end of the turntable also rotate in the same direction. At this time, the second motor drives the driving gear to rotate through the connecting shaft, and the cooperating gear whose tooth grooves mesh with the driving gear is also driven. The cooperating gear drives the grinding disc to rotate at high speed. When the turntable rotates, the pulleys on the outer periphery approach the grinding disc continuously during clockwise rotation until they come into contact with it. The high-speed rotating grinding disc and the protruding annular structure on the outer periphery perform grinding operations on the pulley and the inner groove. At the same time, the high-speed rotating grinding disc also drives the pulley through friction, making it rotate with the shaft on the outer side of the turntable as a support. During the continuous rotation of the turntable, the ground pulley comes into contact with the cleaning brush. Since the pulley is still in a rotating state at this time, the outer annular surface is integrally rubbed during contact with the cleaning brush, thereby scraping off the attached debris generated by grinding. The pulley repeats the above steps continuously until the grinding requirements are met; through the above process, this device can not only integrate multiple groups of pulleys for automated grinding operations, but also automatically clean the possible metal debris in the inner grooves of the pulleys while reducing labor costs.

The control panel 2 is arranged on the front surface of the device main body 1. The control panel 2 controls the first motor 101 and the second motor 3. The second motor 3 is arranged inside the device main body 1, and the second motor 3 drives the grinding disc 4;

[0025] On one side inside the device main body 1, there is a grinding disc 4. The grinding disc 4 performs external grinding on the pulley 6. On the outside of the grinding disc 4, there is a turntable 5. The turntable 5 drives the pulley 6 to move. On the outer end surface of the turntable 5, there is a pulley 6;

[0026] The grinding disc 4 further includes a coupling gear 401, a driving gear 402, and a connecting shaft 403. The coupling gear 401 is welded to the side end of the grinding disc 4. The tooth groove of the driving gear 402 meshes with the coupling gear 401. The connecting shaft 403 is movably connected to the middle of the rear end of the driving gear 402.

[0027] In this embodiment, the other end face of the connecting shaft 403 extends towards the second motor 3 and passes through the inside of the device main body 1 to establish a movable connection relationship with the second motor 3; the device main body 1 further includes a first motor 101 and a cleaning brush 102. The first motor 101 is fixedly installed inside the inner wall of the device main body 1 and extends outward. The cleaning brush 102 is adhesively and fixedly connected to the inner bottom of the device main body 1;

[0028] Specifically, by connecting the second motor 3 through the connecting shaft 403, the driving force of the second motor 3 can be transmitted to the driving gear 402, and a complete transmission mechanism can be constructed;

[0029] In this embodiment, the cleaning brush 102 is an upwardly convex curved surface structure as a whole. It is made of a colloid material as a whole, has high flexibility, and strip-shaped structures extending outward are arranged on the arc surface of its upper surface; the first motor 101 is movably connected to the rear end of the turntable 5, and a shaft seat structure is arranged at the connection position;

[0030] Specifically, by providing the cleaning brush 102 made of a colloid material and designing it as an upwardly convex arc surface structure, it can shrink itself when contacting the pulley 6 and continuously increase the friction force, so as to enhance the cleaning effect of metal chips;

[0031] In this embodiment, eight sets of axially extending structures are provided at one end of the turntable 5 facing outward, and there is an active connection relationship between the axially extending structure and the pulley 6; the rotation speed of the turntable 5 is adjusted by the first motor 101, and the turntable 5 adopts a clockwise rotation operation process.

[0032] The working principle and usage process of the present utility model: When the equipment is performing grinding operations on the pulley 6, the operator can install up to eight sets of pulleys 6 on the axles on the outer peripheral end face of the turntable 5, and then control the first motor 101 and the second motor 3 through the control panel 2. After the first motor 101 and the second motor 3 are started, the first motor 101 drives the turntable 5 to rotate. At this time, the pulley 6 fixedly connected to the front end of the turntable 5 also rotates in the same direction. At this time, the second motor 3 drives the driving gear 402 to rotate through the connecting shaft 403, and the coupling gear 401 engaged with the tooth groove of the driving gear 402 is also driven. The coupling gear 401 drives the grinding disc 4 to rotate at a high speed. When the turntable 5 rotates, the pulley 6 on the outer periphery continuously approaches the grinding disc 4 during clockwise rotation until it comes into contact with the grinding disc 4. The high-speed rotating grinding disc 4 and the protruding annular structure on the outer periphery perform grinding operations on the pulley 6 and the inner groove. At the same time, the high-speed rotating grinding disc 4 also drives the pulley 6 through friction, so that the pulley 6 rotates with the support of the axle on the outer side of the turntable 5. During the continuous rotation of the turntable 5, the ground pulley 6 comes into contact with the cleaning brush 102. Since the pulley 6 is still in a rotating state at this time, the outer annular surface is integrally rubbed during contact with the cleaning brush 102, thereby scraping off the attached debris generated during grinding. The pulley 6 continuously repeats the above steps until the grinding requirements are met.

[0033] Finally, it should be noted that the above are only preferred embodiments of the present utility model and are not used to limit the present utility model.
