[0002] A gear refers to a mechanical element with teeth on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. With the development of production, the smooth operation of gears has received attention.

[0003] According to a disclosed gear deburring device (publication number: CN219380102U), in the above application, by setting a threaded rod, when gears of different sizes are sleeved, the limit rod can be unscrewed from the mounting plate for replacement. The outer thread of the limit rod is connected with a limit ring. By setting the limit ring, after the gear is sleeved on the limit rod, the limit ring is screwed on to prevent the gear from shaking up and down during the deburring process, which affects the deburring effect.

[0004] When this device wants to deburr gears with different inner diameters, the limit rod needs to be disassembled and a limit rod with a suitable size needs to be replaced and installed again, which is very troublesome to use. If multiple gears with different inner diameters need to be processed, the processing efficiency will be seriously affected. Content of the Utility Model

Specific implementation mode

[0024] As Figures 1 - 5 shown, the present utility model provides a technical solution: a burr cleaning device for the surface of a gear, including a machine body 1, a storage table 2 is fixedly installed on the inner wall of the machine body 1, a sliding groove 3 is opened on the storage table 2, a driving cylinder 4 is fixedly installed on the top of the machine body 1, a mounting plate 5 is fixedly installed at the piston end of the driving cylinder 4. Starting the driving cylinder 4 drives the mounting plate 5 to move downward, and the mounting plate 5 drives the motor 6 and the disc brush 7 to move downward until the bristles of the disc brush 7 are in contact with the gear. A motor 6 is fixedly installed at the bottom of the mounting plate 5, and a disc brush 7 is fixedly installed at the output end of the motor 6. Starting the motor 6 drives the disc brush 7 to rotate, and the burrs on the surface of the gear can be polished by the rotation of the disc brush 7. A positioning mechanism 8 for conveniently positioning the gear is arranged inside the machine body 1. By setting the positioning mechanism 8, gears of different sizes can be quickly positioned. A protection mechanism 9 for preventing debris from splashing is arranged on the machine body 1. By setting the protection mechanism 9, it can be avoided that metal waste chips splash and injure the staff during the polishing of the gear.

[0025] The above-mentioned positioning mechanism 8 includes a slider 81, a lifting cylinder 82, a spring 83, a positioning rod 84, a triangular pyramid 85, and a rubber sleeve 86; the slider 81 is slidably connected to the inner wall of the sliding groove 3, and a positioning rod 84 is fixedly installed on the side wall of the slider 81. At this time, by moving the triangular pyramid 85 upward, the three positioning rods 84 can be moved synchronously and away from each other until the three positioning rods 84 are in contact with the inner wall of the gear, and the positioning of the gear can be completed. A rubber sleeve 86 is sleeved on the outer wall of the positioning rod 84, and the rubber sleeve 86 and the positioning rod 84 are in interference fit. The friction between the positioning rod 84 and the inner wall of the gear can be increased through the rubber sleeve 86. The lifting cylinder 82 is fixedly installed on the inner wall of the machine body 1, and a triangular pyramid 85 is fixedly installed at the piston end of the lifting cylinder 82. The bottom of the positioning rod 84 is in contact with the outer wall of the triangular pyramid 85. Starting the lifting cylinder 82 drives the triangular pyramid 85 to move upward. At this time, the triangular pyramid 85 will squeeze the positioning rod 84, so that the positioning rod 84 drives the slider 81 to slide on the inner wall of the sliding groove 3. One end of the spring 83 is fixedly installed on the side wall of the slider 81, and the other end of the spring 83 is fixedly installed on the inner wall of the sliding groove 3.

[0026] The above-mentioned protection mechanism 9 includes an L-shaped rod 91 and a protective cover 92; the L-shaped rod 91 is fixedly installed on the inner wall of the triangular pyramid 85, and the top of the L-shaped rod 91 penetrates through the machine body 1 and is fixedly installed with a protective cover 92. The protective cover 92 can cover the periphery of the placing table 2 to prevent metal scraps from splashing and injuring the staff during the polishing of the gear. The penetration part of the L-shaped rod 91 and the machine body 1 is slidably connected. When the lifting cylinder 82 drives the triangular pyramid 85 to move upward, the L-shaped rod 91 will be driven to move upward synchronously, so that the L-shaped rod 91 drives the protective cover 92 to move upward and protrude from the placing table 2.

[0027] Working principle: First, place the gear on the placing table 2, and then start the lifting cylinder 82 to drive the triangular pyramid 85 to move upward. At this time, the triangular pyramid 85 will squeeze the positioning rod 84, so that the positioning rod 84 drives the slider 81 to slide on the inner wall of the chute 3 and stretch the spring 83. At this time, by moving the triangular pyramid 85 upward, the three positioning rods 84 can move synchronously and move away from each other until the three positioning rods 84 fit against the inner wall of the gear, and the positioning of the gear can be completed. It is not only more convenient to use, but also can position gears of different sizes. Then start the driving cylinder 4 to drive the mounting plate 5 to move downward, and the mounting plate 5 drives the motor 6 and the disk brush 7 to move downward until the bristles of the disk brush 7 are in contact with the gear. Then start the motor 6 to drive the disk brush 7 to rotate, and the burrs on the surface of the gear can be polished by the rotation of the disk brush 7.

[0028] When the lifting cylinder 82 drives the triangular pyramid 85 to move upward, the L-shaped rod 91 will be driven to move upward synchronously, so that the L-shaped rod 91 drives the protective cover 92 to move upward and protrude from the placing table 2. The protective cover 92 can cover the periphery of the placing table 2 to prevent metal scraps from splashing and injuring the staff during the polishing of the gear.

[0029] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
