[0002] Chamfering the edge of a brake disc refers to the bevel cutting process at the junction of the friction surface and the side of the brake disc to form a smooth transition bevel structure. This process is mainly used to eliminate edge burrs or raised corners of the brake disc caused by long-term use, prevent abnormal friction between the newly replaced brake pads and the edge of the brake disc, thereby reducing abnormal brake noise and eccentric wear. A polishing machine device is required for the chamfering of automobile brake discs.

A closed-loop abrasive belt system consisting of three transmission wheels is adopted, which is driven by a motor 1, so that the abrasive belt forms a continuous cutting track on the edge of the brake disc.

Cooperating with the operation of the servo motor, the feeding accuracy of the moving seat is accurate and the chamfering depth is controlled, which is higher than the traditional manual feeding accuracy.

A moving mechanism 300 is provided on the top of the box body 101 and can reciprocate the rotating mechanism 400 in a straight line.

[0037] When in use, the grinding and chamfering mechanism 200 includes a frame 201 fixedly connected to the top of the box body 101, a rotating rod 202 is rotatably connected to the frame 201, a slider 203 is slidably connected to the frame 201, a rotating rod 204 is rotatably connected to the slider 203, a motor 1 205 is fixedly connected to the frame 201, and the output shaft of the motor 1 205, the rotating rod 1 202 and one end of the rotating rod 204 are all fixedly connected to the transmission wheel 206, and the transmission wheel 206 is transmission-connected to the sanding belt 207.

[0038] Specifically, in the present invention, the rotating rod 202 is rotatably connected to the frame 201 through a bearing, and the rotating rod 204 is rotatably connected to the slider 203 through a bearing. Through the setting of the transmission wheel 206, the transmission wheel 206 thereon can be rotated under the drive of the motor 1 205, and then the sanding belt 207 and multiple transmission wheels 206 can rotate together, so that the rotating sanding belt 207 can grind and chamfer the edge of the brake disc that is gradually approaching.

[0039] During use, a screw rod 208 is threadedly connected to the top of the frame 201, the lower end of the screw rod 208 is rotatably connected to the top of the slider 203, the upper end of the screw rod 208 is fixedly connected to the handle 209, and a fixing bolt 210 is threadedly connected to the slider 203, and one end of the fixing bolt 210 contacts the surface of the frame 201.

[0040] Specifically, in the present invention, the lower end of the screw 208 is rotatably connected to the slider 203 through a bearing, and the screw 208 can be moved by rotating the handle 209, thereby adjusting the position of the slider 203, thereby adjusting the height of the rotating rod 204 and the transmission wheel 206 thereon, and adjusting the tightness of the sanding belt 207 on the transmission wheel 206 to ensure the quality of grinding and chamfering. The slider 203 after height adjustment can be reinforced by the fixing bolt 210 to avoid the situation where the screw 208 becomes loose due to vibration and rotates, causing the slider 203 to move.

[0041] When in use, the moving mechanism 300 includes a base 301 fixedly connected to the top of the box body 101, a motor 2 302 is fixedly connected to one side of the base 301, the output shaft of the motor 2 302 is fixedly connected to a screw rod 303, one end of the screw rod 303 is rotatably connected to the base 301, a moving block 304 is threadedly sleeved on the screw rod 303, and a moving seat 305 is fixedly connected to the top of the moving block 304.

[0042] Specifically, in the present invention, the operation of motor 2 302 can rotate the screw rod 303, thereby moving the movable block 304 and the movable seat 305, and moving the brake disc installed on the fixing mechanism 500, so that it is close to the rotating sanding belt 207 for grinding and chamfering, and moves away after completing the edge chamfering.

[0043] During use, a guide block 306 is slidably connected to the base 301 , and the guide block 306 is fixedly connected to the bottom of the movable base 305 . A telescopic rubber cover 307 is fixedly connected to the movable base 305 , and one end of the telescopic rubber cover 307 is fixedly connected to the surface of the base 301 .

[0044] Specifically, in the present invention, a guide groove that cooperates with the guide block 306 is provided on the base 301, and the guide block 306 is used to guide and limit the moving block 304 and the moving seat 305. By setting a telescopic rubber cover 307, the exposed part of the groove for installing the screw rod 303 can be shielded, and at the same time, it can be telescopic without affecting the normal movement of the moving seat 305, thereby preventing waste chips from entering the groove and adhering to the screw rod 303 to affect the rotation.

[0045] When in use, the rotating mechanism 400 includes a turntable 401 rotatably connected to the top of the mobile seat 305, a support plate 402 is fixedly connected to the top of the turntable 401, and an electric telescopic rod 403 is rotatably connected to the turntable 401, and one end of the electric telescopic rod 403 is rotatably connected to the mobile seat 305.

[0046] Specifically, in the present invention, the turntable 401 is rotatably connected to the movable seat 305 via a bearing. By controlling the extension and retraction of the electric telescopic rod 403, the turntable 401 can be rotated forward or reversed, thereby causing the support plate 402 to rotate forward or reversed, so that the brake disc installed on the fixing mechanism 500 is swung to the left and then fixed, or swung to the right and then fixed, and then contacts the surface of the rotating sanding belt 207 as it moves, thereby realizing the grinding and chamfering of the edges on both sides of the brake disc.

[0047] When in use, the fixing mechanism 500 includes a rotating column 501 rotatably connected to the support plate 402, one end of the rotating column 501 is fixedly connected to the limiting plate 502, a positioning rod 503 is fixedly connected to the surface of the limiting plate 502, and a plurality of clips 504 are slidably connected inside the rotating column 501, and there is an inclination angle between the axis of the clip 504 and the axis of the rotating column 501.

[0048] Specifically, in the present invention, the rotating column 501 is rotatably connected to the support plate 402 through a bearing. Through the setting of the limit plate 502, the brake disc is put on the positioning rod 503 and then limited. There are four positioning rods 503. Through the setting of the positioning rods 503, after the through hole on the brake disc is put on it, the brake disc is limited longitudinally so that it does not move up and down, and after the limit plate 502 contacts it, one side of the brake disc is limited. There are three clips 504. By pulling the clip 504, one end of the clip is in contact with the other side of the brake disc, and then the brake disc is fixedly installed on the limit plate 502.

[0049] When in use, the support plate 402 is fixedly connected to a connecting plate 505, and the connecting plate 505 is fixedly connected to an electric telescopic rod 2 506. One end of the electric telescopic rod 2 506 is rotatably connected to a round block 507, and one side of the round block 507 is fixedly connected to a guide frame 508. One end of the buckle 504 is fixedly connected to a short column 509, and the short column 509 is slidably connected to the inner cavity of the guide frame 508.

[0050] Specifically, in the present invention, the electric telescopic rod 506 is fixedly connected to the connecting plate 505, and the output end of the electric telescopic rod 506 is rotatably connected to the round block 507 through a bearing. Through such an arrangement, the electric telescopic rod 506 can drive the round block 507 to move when it is extended and retracted, and at the same time, the normal rotation of the round block 507 will not be affected when it rotates. The arrangement of the guide frame 508 and the short column 509 makes an indirect connection between the buckle 504 and the round block 507, so that when the electric telescopic rod 506 is extended and retracted to drive the round block 507 to move, the buckle 504 can slide normally in the rotating column 501, so that the clamping ends of the multiple buckles 504 tilt closer to or away from each other, thereby realizing the release and fixation of the brake disc sleeved on the positioning rod 503. In this process, the short column 509 can move in the guide frame 508 without hindering the tilting movement of the buckle 504, and can move smoothly under its action.

[0051] When in use, the driving mechanism 600 includes a motor three 601 fixedly connected to the support plate 402, the output shaft of the motor three 601 is fixedly connected to a belt pulley one 602, a belt pulley two 603 is fixedly sleeved on the surface of the rotating column 501, and the belt pulley one 602 and the belt pulley two 603 are connected by a belt 604 for transmission.

[0052] Specifically, in the present invention, by controlling the operation of motor 2 302, pulley 2 603 can be rotated, and then belt 604 and pulley 2 603 are rotated, so that the rotating column 501, the limit plate 502, the positioning rod 503 and the brake disc are rotated, so that the brake disc contacts the rotating sanding belt 207 in a rotating manner, thereby achieving grinding and chamfering of the peripheral edge of the side of the brake disc.

[0053] When in use, the top of the box body 101 is fixedly connected to the cover body 102 , and the dust collection assembly 103 is installed on the cover body 102 .

[0054] Specifically, in the present invention, the cover body 102 can shield the device to improve safety and prevent dust from flying into the air. The dust collection component 103 can be set to collect and intercept the dust generated during the processing.

[0055] Working principle of the present invention:

[0056] S1. Place the brake disc on the positioning rod 503 and contact it with the limit plate 502. Control the retraction of the second electric telescopic rod 506 to move the round block 507. Then, with the cooperation of the guide frame 508 and the short column 509, move the buckle 504 so that one end contacts the surface of the brake disc to fix it.

[0057] S2. Control the extension and retraction of the electric telescopic rod 1 403 to rotate the turntable 401 to a certain angle, thereby rotating the support plate 402 and the brake disc to a certain angle, and control the operation of the motor 1 205, the motor 2 302, and the motor 3 601. The operation of the motor 1 205 rotates the sanding belt 207 and the transmission wheel 206. The rotation of the motor 3 601, in coordination with the belt pulley 1 602, the belt 604, and the belt pulley 2 603, rotates the rotating column 501, thereby rotating the limit plate 502, the brake disc, and the positioning rod 503.

[0058] S3, the second motor 302 is operated to rotate the screw 303, thereby driving the moving block 304 and the moving seat 305 to move, so that the brake disc that swings a certain angle and rotates contacts the rotating sanding belt 207, achieving grinding and chamfering on one side;

[0059] S4. After the chamfering of one side is completed, the operation of the second motor 302 is controlled to reset the movable seat 305, and then the extension of the electric telescopic rod 1 403 is controlled to swing the brake disc in the other direction, and then the operation of the second motor 302 is controlled to make the brake disc contact with the sanding belt 207 to perform the chamfering of the edge of the other side.

[0060] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0061] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
