Description

Technical Field

[0001] This utility model belongs to the field of polishing technology, and in particular relates to a belt abrasive device for a polishing machine. Background Technology

[0002] Currently, the processing steps for hardware clamp-type workpieces (hereinafter referred to as workpieces) include casting, grinding, and polishing. In polishing operations, with the development of existing technology, automation is often used to facilitate production. However, general pneumatic polishing machines are not convenient for cyclical operation during processing, which is not conducive to improving work efficiency. They are also not convenient for controlling the tension of the abrasive belt, which is not conducive to rapid production.

[0003] In the grinding and polishing process, it is crucial to quickly and appropriately control the tension of the abrasive belt. A suitable tension ensures that the belt maintains stable contact force and a stable trajectory, thereby improving grinding accuracy and smoothness. However, current tension control is mostly manual, which often fails to achieve high precision. Compared to automation, manual tension adjustment requires more time and manpower, reducing overall production efficiency. Therefore, we propose an electrically controlled tension adjustment device that can more quickly and accurately adjust the appropriate abrasive belt tension, significantly improving production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a belt abrasion device for a polishing machine. By incorporating a tension adjustment component, specifically, a motor drives a gear to rotate, which in turn drives a rack, which in turn drives a pulley to move upwards or downwards. Changing the rotation direction of the motor alters the rotation direction of the gear, thus changing the upward or downward movement of the pulley and controlling the belt tension. A support column ensures greater stability and prevents the belt from slipping due to pressure on the pulley. This device allows for more precise and stable tension adjustment, addressing the crucial importance of quickly and appropriately controlling belt tension during polishing. Appropriate belt tension ensures stable contact force and trajectory during abrasion, improving precision and smoothness. However, current tension control is mostly manual, which often fails to achieve high precision. Compared to automation, manual tension adjustment requires more time and manpower, reducing overall production efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a belt abrasive device for a polishing machine, comprising a base, a polishing assembly, and a tension adjustment assembly. The tension adjustment assembly includes two brackets fixedly connected to the top of the base. A motor is mounted on the front of each bracket, with its bottom fixedly connected to the top of the base. A pulley is fixedly connected to the output end of the back of the motor. Motors are fixedly connected to the center of the inner sides of the two brackets. A gear is fixedly connected to the output end of the right side of each motor. A rack is slidably connected to the inner side of the rear bracket. A limiting groove is formed on the inner side of the rear bracket. A limiting rod is fixedly connected to the back of the rack. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting rod. The back of the gear is connected to the rack. The device features a front-mounted meshing connection. A support column is slidably connected to the inner side of the front-mounted bracket two. A limit groove two is formed on the inner side of the front-mounted bracket two. A limit rod two is fixedly connected to the front of the support column. The inner wall of the limit groove two is slidably connected to the outer side of the limit rod two. Rings are fixedly connected to the top of both the rack and the support column. A pulley three is positioned above the motor two. The front and back of the pulley three are rotatably connected to the inner walls of the two rings. By changing the rotation direction of the motor one, the rotation direction of the gears is changed, thereby changing the upward or downward movement of the pulley one, thus controlling the tension of the sanding belt. The support column ensures greater stability of the device and prevents the sanding belt from slipping off due to pressure on the front of the pulley three. This device makes tension adjustment more precise and stable.

[0007] Furthermore, the polishing assembly includes two brackets fixedly connected to the top of the base. A polishing platform is fixedly connected to the left side of the brackets. A groove is provided at the center of the top of the polishing platform. A movable fixed platform is slidably connected to the top of the polishing platform. A protrusion is fixedly connected to the center of the bottom of the movable fixed platform. The protrusion at the bottom of the movable fixed platform is slidably connected to the inner wall of the groove at the center of the polishing platform. The movable fixed platform makes polishing objects more convenient and can be used for polishing more objects.

[0008] Furthermore, a fixing component is provided on the top of the mobile fixed platform. The fixing component includes a fixing push plate that is slidably connected to the top of the mobile fixed platform. A limit ring is fixedly connected to the front of the fixing push plate. The limit ring ensures that the fixed top plate will not move in other directions or detach from the mobile fixed platform.

[0009] Furthermore, a fixing cylinder is provided on the front of the limiting ring, and a fixing base is fixedly connected to the top of the mobile fixing platform. The bottom of the fixing cylinder is fixedly connected to the top of the fixing base, and the fixing of the fixing base makes the fixing effect of the entire fixing device more stable.

[0010] Furthermore, a threaded rod is threadedly connected to the inner wall of the fixed cylinder, and the back of the threaded rod is rotatably connected to the inner side of the limiting ring. A pulley is rotatably connected to the inner side of the top of the bracket, and the back of the threaded rod rotates within the limiting ring, which not only ensures the normal operation of the threaded rod but also limits the threaded rod.

[0011] Furthermore, a second pulley is provided below the first pulley. The inner bottom sides of both brackets are rotatably connected to the front and back of the second pulley. A slag collection box is provided on the left bottom side of the bracket. A baffle is fixedly connected to the outer top of the bracket. Two limiting grooves are provided on the right side of the baffle. A lifting protective shell is slidably connected to the right side of the baffle. Two limiting rods are fixedly connected to the left side of the lifting protective shell. The inner wall of the limiting groove is slidably connected to the outer surface of the limiting rod. During the grinding process, the residue from the grinding will fall into the slag collection box and be collected. The splashed residue will be blocked by the baffle and the lifting protective shell. The lifting protective shell also moves up or down with the first pulley to protect the sanding belt from damage by foreign objects. The baffle reduces the scattering of debris, improves the surrounding environment, and at the same time reduces splashing to protect the workers from injury.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by setting up a tension adjustment component, specifically involves starting a motor to drive a gear to rotate, the gear to drive a rack, and the rack to drive a pulley to move upward or downward. By changing the rotation direction of the motor, the rotation direction of the gear is changed, thereby changing the upward or downward movement of the pulley and controlling the tension of the sanding belt. The support column ensures that the device is more stable and prevents the sanding belt from falling off due to pressure on the three sides of the pulley. This device makes the tension adjustment more precise and stable.

[0014] 2. This utility model sets up a movable fixing platform. Specifically, the threaded rod rotates clockwise to drive the fixed push plate to move towards the object position. After the fixed push plate contacts the object, it clamps and fixes the object in cooperation with the movable fixing platform. This avoids the situation where the object will fall from the hand and be blown away by the sanding belt when sanding by hand. At the same time, it avoids the worker's hands from coming into contact with the sanding belt, thus improving safety.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The protrusion at the bottom of the movable fixed platform 31 is slidably connected to the inner wall of the groove provided at the center of the polishing platform 3.

[0032] The top of the mobile fixed platform 31 is provided with a fixing component 32, which includes a fixing push plate 321 that is slidably connected to the top of the mobile fixed platform 31. A limit ring 322 is fixedly connected to the front of the fixing push plate 321.

[0033] The limiting ring 322 has a fixed cylinder 325 on its front side, and the fixed base 323 is fixedly connected to the top of the movable fixed platform 31. The bottom of the fixed cylinder 325 is fixedly connected to the top of the fixed base 323.

[0034] The inner wall of the fixed cylinder 325 is threaded with a threaded rod 324. The back of the threaded rod 324 is rotatably connected to the inner side of the limiting ring 322. The top inner side of the bracket 111 is rotatably connected with a pulley 112.

[0035] A second pulley 113 is provided below the first pulley 112. The inner bottom sides of the two brackets 111 are rotatably connected to the front and back sides of the second pulley 113.

[0037] A specific application of this embodiment is as follows: Starting motor 4 drives pulley 4 123 to rotate, which in turn drives the sanding belt. The sanding belt drives pulley 2 113, pulley 1 112, and pulley 3 122 to rotate. Pulley 3 122 rotates within the ring connected to the top of rack 211 and support column 212. Starting motor 2 114 drives gear 141 to rotate, which in turn moves rack 211 up or down. Rack 211 then moves pulley 1 112 up or down to change the sanding belt tension. When pulley 1 112 moves, it moves support column 212 up or down. Because rack 211 and support column 212 respectively drive limit rod 1 213 and limit rod 2 214 to slide within limit groove 1 215 and limit groove 216, the stability of pulley 1 112 is improved. This method is more efficient and precise than manual tension adjustment. The object to be sanded is placed on the movable fixed platform 31, and the screw is rotated... The handle on the front of the threaded rod 324 drives the threaded rod 324 to move forward or backward within the fixed cylinder 325. The top of the back of the threaded rod 324 rotates inside the limiting ring 322 and drives the limiting ring 322 to move together. The clockwise rotation of the threaded rod 324 drives the fixed push plate 321 to move towards the object position. After the fixed push plate 321 contacts the object, it clamps and fixes the object in cooperation with the moving fixed platform 31, avoiding the situation where the object will fall from the hand and be blown away by the sanding belt when sanding by hand. At the same time, it avoids the worker's hands from coming into contact with the sanding belt, improving safety. The sanding residue will fall into the slag collection box 2 and be collected during the sanding process. The splashed residue will be blocked by the baffle 6 and the lifting protective shell 5. The lifting protective shell 5 also moves up or down with the pulley 112 to protect the sanding belt from damage by foreign objects. The baffle 6 reduces the scattering of debris, improves the surrounding environment, and at the same time reduces splashing to protect the worker from injury.
