Description

Technical Field

[0001] The present invention relates to the technical field of motorcycle assembly testing, and particularly relates to a motorcycle caliper drag test device based on laser scanning. Background Art

[0002] The drag force of a motorcycle caliper is a residual stress, which generally appears in a hydraulic piston caliper. The brake piston is pushed by hydraulic oil in the working cylinder to achieve the purpose of braking. When the brake piston does not return completely, residual stress will be generated, that is, the drag force. If the drag force is greater than the standard set value, even if the motorcycle brake is released, a residual frictional force will be formed between the brake pad and the caliper. The existence of excessive drag force will not only cause abnormal wear of the brake pad and the caliper, but also reduce the fuel economy of the motorcycle and increase fuel consumption.

[0003] Therefore, in the process of motorcycle production, in order to meet the actual use standards, it is necessary to test the caliper drag force. Most of the existing test devices use a torque sensor connected between the motor and the brake pad to detect the change in the torque of the brake pad after the caliper is released. Whether there is drag can only be indirectly judged by the change in torque, and the drag degree of the caliper on the brake pad cannot be intuitively displayed. Summary of the Invention

[0004] The purpose of the present invention is to provide a motorcycle caliper drag test device based on laser scanning. Based on the bottom frame member and the fixed insertion component, through the cooperative transmission formed by the rotary caliper component and the push rod component, it can not only facilitate the non-interference installation of the brake pad and the caliper respectively, but also realize the rapid and safe assembly of the caliper and the brake pad.

[0005] The purpose of the present invention is achieved through the following technical solution. A motorcycle caliper drag test device based on laser scanning includes a bottom frame member, a fixed insertion component, a rotary caliper component and a push rod component. The fixed insertion component includes a main rotary hexagonal column and a mating seat. The rotary caliper component includes a rotary arm and an inclined connecting rod. The push rod component includes a clamping vertical seat, a conical hexagonal column, a conical hexagonal groove and a follower slider;

[0006] The main rotary hexagonal column is rotatably connected to one side of the top end of the bottom frame member. The conical hexagonal groove is horizontally opened in the middle of the main rotary hexagonal column. The mating seat is inserted and assembled with the main rotary hexagonal column. A brake pad to be tested is installed on one side of the mating seat. A follower sliding hole is opened in the main body of the main rotary hexagonal column, and a clamping hole is opened in the main body of the mating seat;

[0007] The bottom end of the rotary arm is rotatably connected to the top end of the bottom frame member. A caliper is installed at the top end of the rotary arm. A movable pushing plate is slidably connected to the inner bottom surface of the top end of the bottom frame member. One end of the inclined connecting rod is rotatably connected to the pushing plate, and the other end is rotatably connected to the middle of the main body of the rotary arm;

[0008] The top end of the bottom frame member is provided with a rotatable main shaft sleeve. The clamping seat slides on the top end of the bottom frame member. The conical hexagonal column is screwed to the top end of the clamping seat, and one end of the conical hexagonal column is slidably inserted into the main shaft sleeve. The other end of the conical hexagonal column is provided with a pushing inclined groove. The follower slider is slidably inserted into the follower sliding hole, and the bottom surface of the follower slider is tangent to the inner bottom surface of the pushing inclined groove. The clamping seat is in transmission connection with the pushing plate.

[0009] The use process of the technical solution of the present invention is as follows:

[0010] One side of the mating seat can be threadedly connected to the brake pad to be tested. Similarly, the top end of the swing arm can also be installed with the caliper to be tested, and the caliper is connected to an external brake through an oil pipe.

[0011] The automatic movement of the pushing plate can drive the swing arm to form a rotational movement through an inclined connecting rod screwed between the pushing plate and the middle part of the swing arm. The rotation of the swing arm can drive the caliper and the main rotating hexagonal column away from each other.

[0012] During the process of the pushing plate driving the caliper and the main rotating hexagonal column away from each other, it will drive the clamping seat and the conical hexagonal column to move away from the conical hexagonal groove through the cooperation transmission formed by the pushing plate and the clamping seat. During this process, the follower slider is always inserted and slid in the follower sliding hole and will not be separated from the follower sliding hole. As the conical hexagonal column moves away from the conical hexagonal groove, through the tangential fit of the inclined plane formed by the follower slider and the pushing inclined groove, the follower slider will be received into the follower sliding hole.

[0013] After the brake pad is connected to the mating seat, the mating seat can be inserted and mated with the main rotating hexagonal column until the position of the card hole is aligned with the position of the follower sliding hole.

[0014] Then hold the brake pad by hand and make the pushing plate move automatically again, driving the rotation of the swing arm, so that the caliper can be assembled in place with the brake pad. On the other hand, the pushing plate drives the clamping seat and the conical hexagonal column to move towards the conical hexagonal groove through the cooperation transmission formed with the clamping seat. When the caliper is assembled in place with the brake pad, the conical hexagonal column can just be inserted into the conical hexagonal groove in place. And the movement of the conical hexagonal column towards the conical hexagonal groove can also drive the ejection of the follower slider through the tangential fit of the inclined plane formed by the follower slider and the pushing inclined groove, so that the follower slider is inserted into the plug-in hexagonal groove aligned with the follower sliding hole.

[0015] And after the conical hexagonal column is inserted and mated with the conical hexagonal groove in place, the outer surface of the conical hexagonal column and the inner surface of the conical hexagonal groove are in one-to-one alignment and fit. The rotatable main shaft sleeve can drive the rotation of the conical hexagonal column. The mating of the conical hexagonal column inserted into the conical hexagonal groove in place can drive the rotation of the main rotating hexagonal column, and can drive the mating seat and the brake pad to form a continuous rotation at a certain speed.

[0016] And the laser scanning device is located directly above the caliper, capable of visually scanning the positional relationship between the outside of the brake pad and the friction pad of the caliper;

[0017] Subsequently, through the external brake connected to the caliper, the caliper clamps the brake pad during rotation, and the driving mechanism that drives the rotation of the main shaft sleeve is stopped. The clamping state formed by the friction pad of the caliper against the outside of the brake pad will cause the brake pad to stop quickly;

[0018] After the brake pad stops rotating, the external brake connected to the caliper is released, and the driving mechanism connected to the main shaft sleeve is started synchronously. At this time, the movement of the hydraulic brake piston in the external brake takes a certain amount of time. After the external brake connected to the caliper is released, a residual frictional force will be formed between the friction pad of the caliper and the outside of the brake pad, forming a drag force;

[0019] By using the laser scanning device facing the caliper, the degree of drag can be tested by the relationship between the change in the distance between the friction pad of the caliper and the outside of the brake pad scanned in real time and time.

[0020] By adopting the above technical solutions, the present invention can achieve the following beneficial effects:

[0021] (1) Through the automatic movement of the push plate to drive the rotating action of the swing arm within a certain range, the present invention can move the top of the swing arm to a position far from the main rotating hexagonal column, facilitating the quick and convenient installation of the brake pad and the caliper at positions where they do not interfere with each other;

[0022] (2) After the push plate drives the swing arm to rotate to a position far from the main rotating hexagonal column, the transmission cooperation formed by the push plate and the clamping seat can also drive the clamping seat and the tapered hexagonal column to move away from the tapered hexagonal groove. The tangent cooperation between the matching push groove and the follower slider enables the follower slider to be received into the follower slide hole, facilitating the smooth insertion and connection of the mating seat and the main rotating hexagonal column;

[0023] (3) During the process of the push plate driving the swing arm and the caliper to rotate to the test position, the movement of the push plate can also drive the clamping seat and the tapered hexagonal column to move closer to the tapered hexagonal groove, causing the follower slider to be inserted into the clamping hole. Thus, not only can the quick insertion and assembly of the mating seat and the main rotating hexagonal column be achieved before the test, but also after the caliper and the brake pad are assembled in place, the stable connection between the mating seat and the main rotating hexagonal column can be realized by the follower slider extending into the clamping hole.

In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0041] AsFigures 1 - 12 As shown in the figure, a motorcycle caliper drag test device based on laser scanning. One side above the top end of the bottom frame member 1 is rotatably connected with a main rotating hexagonal column 203. A tapered hexagonal groove 412 is horizontally opened in the middle of the main rotating hexagonal column 203. A mating seat 204 is inserted and assembled with the main rotating hexagonal column 203. One side of the mating seat 204 is equipped with a brake pad 208 to be tested. A follower sliding hole 415 communicating with the tapered hexagonal groove 412 is opened in the main body of the main rotating hexagonal column 203. A clamping hole 206 is opened in the main body of the mating seat 204. And after the mating seat 204 is inserted and assembled with the main rotating hexagonal column 203 in place, the clamping hole 206 is directly opposite to the follower sliding hole 415;

[0042] The bottom end of the rotating arm 302 is rotatably connected to the top end of the bottom frame member 1. A caliper 304 is installed at the top end of the rotating arm 302. A movable push plate 310 is slidably connected to the inner bottom surface of the top end of the bottom frame member 1. One end of the inclined connecting rod 306 is rotatably connected to the push plate 310, and the other end is rotatably connected to the middle part of the main body of the rotating arm 302;

[0043] A rotatable main shaft sleeve 403 is provided at the top end of the bottom frame member 1. A clamping seat 406 is slidably connected to the top end of the bottom frame member 1. A tapered hexagonal column 411 is rotatably connected to the top end of the clamping seat 406. One end of the tapered hexagonal column 411 is slidably inserted and matched with the main shaft sleeve 403. A pushing inclined groove 417 is opened at the other end of the tapered hexagonal column 411. A follower slider 416 is slidably inserted into the follower sliding hole 415. And the bottom surface of the follower slider 416 is tangent to the inner bottom surface inclined plane of the pushing inclined groove 417. The clamping seat 406 is in transmission connection with the push plate 310. After the push plate 310 moves to drive the caliper 304 away from the main rotating hexagonal column 203, it can synchronously drive the tapered hexagonal column 411 away from the tapered hexagonal groove 412 through the formed transmission connection with the clamping seat 406, so that the follower slider 416 is received into the follower sliding hole 415, which is convenient for inserting the mating seat 204 and the main rotating hexagonal column 203 without interference; after the mating seat 204 and the main rotating hexagonal column 203 are inserted and matched, after the push plate 310 moves to drive the caliper 304 to cooperate with the brake pad 208 in place, it can synchronously drive the tapered hexagonal column 411 to insert into the tapered hexagonal groove 412 and push the follower slider 416 out into the clamping hole 206, so that the mating seat 204 and the main rotating hexagonal column 203 are safely assembled;

[0044] The working principle is as follows:

[0045] One side of the mating seat 204 can be threadedly connected with the brake pad 208 to be tested. Similarly, the caliper 304 to be tested can also be installed at the top end of the rotating arm 302. And the caliper 304 is connected to an external brake through an oil pipe;

[0046] When installing the brake pad 208 to be tested, in order to prevent the caliper 304 from interfering with the installation of the brake pad 208, the caliper 304 needs to be moved to a position away from the main rotating hexagonal column 203. The automatic movement of the push plate 310 can drive the rotating arm 302 to rotate through the inclined connecting rod 306 screwed between the middle parts of the push plate 310 and the rotating arm 302. The rotation of the rotating arm 302 can drive the caliper 304 away from the main rotating hexagonal column 203;

[0047] During the process of the push plate 310 driving the caliper 304 away from the main rotating hexagonal column 203, the mating transmission formed by the push plate 310 and the clamping seat 406 will drive the clamping seat 406 and the conical hexagonal column 411 to move away from the conical hexagonal groove 412. During this process, the follower slider 416 is always inserted and slides in the follower slide hole 415 and will not disengage from the follower slide hole 415. As the conical hexagonal column 411 moves away from the conical hexagonal groove 412, through the tangential mating of the inclined surface formed by the follower slider 416 and the pushing inclined groove 417, the follower slider 416 will be received into the follower slide hole 415. At this time, the follower slider 416 will not interfere with the insertion and assembly of the mating seat 204 and the main rotating hexagonal column 203;

[0048] After the brake pad 208 is connected to the mating seat 204, the mating seat 204 can be inserted and mated with the main rotating hexagonal column 203 until the position of the card hole 206 is directly opposite to the position of the follower slide hole 415;

[0049] Subsequently, hold the brake pad 208 by hand and make the push plate 310 move automatically again, driving the rotation of the rotating arm 302, so that the caliper 304 can be assembled in place with the brake pad 208. On the other hand, the push plate 310 drives the clamping seat 406 and the conical hexagonal column 411 to move towards the conical hexagonal groove 412 through the mating transmission formed with the clamping seat 406. When the caliper 304 is assembled in place with the brake pad 208, the conical hexagonal column 411 can just be inserted into the conical hexagonal groove 412 in place, and the movement of the conical hexagonal column 411 towards the conical hexagonal groove 412 can also drive the ejection of the follower slider 416 through the tangential mating of the inclined surface formed by the follower slider 416 and the pushing inclined groove 417, so that the follower slider 416 is inserted into the plug-in hexagonal groove 205 directly opposite to the follower slide hole 415, ensuring that the mating seat 204 will not disengage from the main rotating hexagonal column 203 during the test process;

[0050] And after the tapered hexagonal column 411 and the tapered hexagonal groove 412 are inserted and fitted in place, the outer surface of the tapered hexagonal column 411 and the inner surface of the tapered hexagonal groove 412 are in one-to-one facing and fitting. The rotatable spindle sleeve 403 can drive the rotation of the tapered hexagonal column 411. The insertion and fitting of the tapered hexagonal column 411 and the tapered hexagonal groove 412 in place can drive the rotation of the main rotating hexagonal column 203. And because the mating seat 204 is firmly connected to the main rotating hexagonal column 203, it can drive the mating seat 204 and the brake pad 208 to rotate continuously at a certain speed;

[0051] And the laser scanning device is located directly above the caliper 304, and can directly scan the positional relationship between the outer surface of the brake pad 208 and the friction lining of the caliper 304;

[0052] And before the test, the distances between the inner friction linings on both sides of the caliper 304 and the outer surfaces on both sides of the brake pad 208 are equal, which can eliminate the adverse effects caused by inaccurate installation of the relative positions of the caliper 304 and the brake pad 208;

[0053] Subsequently, through the external brake connected to the caliper 304, the caliper 304 clamps the rotating brake pad 208, and the driving mechanism that drives the rotation of the spindle sleeve 403 is stopped. The clamping state formed by the friction lining of the caliper 304 on the outer surface of the brake pad 208 will cause the brake pad 208 to stop quickly;

[0054] After the brake pad 208 stops rotating, the external brake connected to the caliper 304 is released, and the driving mechanism connected to the spindle sleeve 403 is started synchronously. At this time, the movement of the hydraulic brake piston in the external brake takes a certain amount of time. After the external brake connected to the caliper 304 is released, a residual frictional force will be formed between the friction lining of the caliper 304 and the outer surface of the brake pad 208, forming a drag force;

[0055] Using the laser scanning device facing the caliper 304, the position between the friction lining of the caliper 304 and the outer surface of the brake pad 208 can be scanned in real time within a certain period of time. By the relationship between the change in the distance between the friction lining of the caliper 304 and the outer surface of the brake pad 208 scanned in real time and time, the degree of drag can be tested;

[0056] And because the transmission between the push plate 310 and the clamping seat 406 cannot be changed, the ratio relationship between the rotation range of the swing arm 302 formed by the movement of the push plate 310 and the moving stroke of the tapered hexagonal column 411 remains unchanged all the time. Therefore, this device is only applicable to the test work of brake pads 208 and calipers 304 of the same specification.

[0057] The specific structures of the chassis member 1 and the fixed insertion member 2 are as Figure 2 and Figure 3As shown in the figure, the bottom end of the bottom plate 101 is fixedly connected with a chassis 102, and the chassis 102 is used for fixedly supporting the bottom plate 101. A fixed seat 201 is fixedly connected to one side of the top end of the bottom plate 101. A main rotating seat 202 is installed and fixed on the upper end of the fixed seat 201. One end of a main rotating hexagonal column 203 is rotatably connected to the main rotating seat 202;

[0058] A plugging hexagonal groove 205 is formed in the middle of the main body of the mating seat 204, and a clamping hole 206 communicates with the plugging hexagonal groove 205. The mating seat 204 can form a plugging assembly with the main rotating hexagonal column 203 through the plugging hexagonal groove 205;

[0059] A limiting sleeve 207 is also fixedly installed on the outer surface of the main rotating hexagonal column 203. The function of the limiting sleeve 207 is to limit the insertion of the mating seat 204 into the outside of the main rotating hexagonal column 203 through the plugging hexagonal groove 205, so that the clamping hole 206 can be accurately aligned with the position of the follower sliding hole 415.

[0060] The specific structure of the rotary caliper assembly 3 is as Figure 4 and Figure 5 shown. A rotary arm seat 301 is fixedly installed on the top end of the bottom plate 101. The bottom end of a rotary arm 302 is rotatably connected to the rotary arm seat 301. A caliper connection seat 303 is fixedly installed at the top end of the rotary arm 302. A caliper 304 is installed and fixed to the caliper connection seat 303 by means of threaded connection;

[0061] A middle connecting shaft 305 is fixedly installed in the middle of the main body of the rotary arm 302. An inclined rod rotary seat 311 is fixedly installed at the bottom end of a pushing plate 310. One end of an inclined connecting rod 306 is rotatably connected to the inclined rod rotary seat 311, and the other end is rotatably connected to the middle connecting shaft 305;

[0062] An inclined rod through hole 307 is formed in the main body of the bottom plate 101 to eliminate interference with the inclined connecting rod 306;

[0063] Pairs of pushing slide rails 308 are fixedly installed on the bottom surface of the bottom plate 101. The pushing plate 310 is slidably connected to the pushing slide rails 308 through pushing sliders 309. The main body of an electric cylinder 312 is fixedly connected to the bottom surface of the bottom plate 101. The telescopic rod of the electric cylinder 312 is fixedly connected to one end of the pushing plate 310, and can drive the pushing plate 310 to accurately move guided by the sliding fit formed by the pushing sliders 309 and the pushing slide rails 308, so as to accurately control the rotary arm 302 to rotate within a certain range with the rotary arm seat 301 as the reference.

[0064] The specific structure of the push rod assembly 4 is as Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10As shown in the figure, the main rotation motor 402 is fixedly installed on the top end of the bottom plate 101 through the main rotation motor base 401, and the main shaft sleeve 403 is fixedly connected to the rotating shaft of the main rotation motor 402;

[0065] On the top end of the bottom plate 101, paired clamping slide rails 404 are fixedly installed, and the clamping upright seat 406 is slidably connected to the clamping slide rails 404 through the clamping sliders 405;

[0066] On the top end of the clamping upright seat 406, a fixed rotation seat 409 is installed and fixed. One end of the conical hexagonal column 411 is fixed with a fixed rotation shaft 410, and one end of the fixed rotation shaft 410 is fixed with a transverse movement hexagonal column 408. The fixed rotation shaft 410 is rotatably connected to the fixed rotation seat 409, and the transverse movement hexagonal column 408 is inserted and matched with the main shaft sleeve 403, and the inserted and matched formed by the transverse movement hexagonal column 408 and the main shaft sleeve 403 is sufficient to support the travel range of the movement of the clamping upright seat 406;

[0067] Start the main rotation motor 402 to drive the rotation of the main shaft sleeve 403. By using the inserted and matched formed by the main shaft sleeve 403 and the transverse movement hexagonal column 408, not only can the rotation actions of the transverse movement hexagonal column 408, the fixed rotation shaft 410, and the conical hexagonal column 411 be realized with the fixed rotation seat 409 as the reference, but also the movement actions of the transverse movement hexagonal column 408, the fixed rotation shaft 410, and the conical hexagonal column 411 along with the movement of the clamping upright seat 406 can be satisfied;

[0068] In the middle of the bottom end of the clamping upright seat 406, a transverse movement lead screw slider 421 is fixedly installed, and a clamping through hole 407 is opened in the main body of the bottom plate 101 to eliminate the movement interference with the transverse movement lead screw slider 421;

[0069] On both sides of the main body of the conical hexagonal column 411, side columns 413 are fixed. On both sides of the inner surface of the conical hexagonal groove 412, side grooves 414 are opened. And within the forming range of the movement of the conical hexagonal column 411, the side columns 413 on the same side are always slidably matched with the side grooves 414. The purpose of setting the side columns 413 and the side grooves 414 is that since the conical hexagonal column 411 and the conical hexagonal groove 412 are mutually matched conical structures, after the conical hexagonal column 411 moves away from the conical hexagonal groove 412, the outer surface of the conical hexagonal column 411 and the inner surface of the conical hexagonal groove 412 will be in a non-contact position with each other. Through the sliding match formed by the side columns 413 and the side grooves 414, on the basis of using the conical structures of the conical hexagonal column 411 and the conical hexagonal groove 412 to ensure the smooth insertion of the conical hexagonal column 411 and the conical hexagonal groove 412, the transverse movement precision of the conical hexagonal column 411 relative to the conical hexagonal groove 412 can be guaranteed;

[0070] On both sides of the lower end of the follower slider 416, side sliders 418 are fixed. On both sides of the inside of the pushing chute 417, side sliding grooves 419 are formed. The side sliders 418 on the same side are slidably connected to the side sliding grooves 419. At both ends of each group of side sliding grooves 419, safety inserts 420 are fixed, enabling the follower slider 416 to slide safely within the pushing chute 417;

[0071] On the bottom surface of the bottom plate 101, pairs of lead screw seats 423 are fixed. The two ends of the transverse movement lead screw 422 are respectively rotatably connected to different lead screw seats 423. A lead screw gear 424 is inserted and fixed at one end of the transverse movement lead screw 422. A rack 425 is fixedly installed on the bottom surface of the pushing plate 310, and the rack 425 meshes with the lead screw gear 424;

[0072] After the pushing plate 310 moves, it can drive the rack 425 to form a cooperative drive with the lead screw gear 424, driving the transverse movement lead screw 422 to rotate synchronously. The transverse movement lead screw 422 forms a cooperative drive with the transverse movement lead screw slider 421, enabling the clamping seat 406 to move synchronously while the pushing plate 310 moves;

[0073] Since the transverse movement lead screw 422 can be set to be left-handed or right-handed according to the actual situation, the movement of the pushing plate 310 can realize the action of the caliper 304 moving away from the main rotating hexagonal column 203, and the clamping seat 406 and the conical hexagonal column 411 moving away from the conical hexagonal groove 412 synchronously; conversely, the caliper 304 moves closer to the main rotating hexagonal column 203, and the clamping seat 406 and the conical hexagonal column 411 move in the direction of the conical hexagonal groove 412 synchronously.

[0074] A schematic diagram of the laser scanning assembly 5 for realizing the scanning detection work of the drag test, and the auxiliary lamp panel module 6 that can provide a unified background for easy scanning and identification for the caliper 304 after the laser scanning probe 506 rotates to the test position facing the caliper 304 is as Figure 11 and Figure 12 shown. The top arm 501 is fixed to one side of the top of the clamping seat 406. The driving rack 502 is fixedly connected to the upper end of the other side of the top arm 501. One side of the top of the fixed seat 201 is fixedly installed with a passive shaft seat 503. A passive shaft 504 is rotatably connected in the passive shaft seat 503. The passive swing arm 505 is fixedly connected to the upper end of the passive shaft 504. The passive gear 507 is fixedly connected to the lower end of the passive shaft 504, and the passive gear 507 meshes with the driving rack 502. The laser scanning probe 506 is installed and fixed on the lower side of the other end of the passive swing arm 505;

[0075] When the clamping and standing base 406 moves towards the fixing base 201 and the main rotating hexagonal column 203, it can synchronously drive the driving rack 502 to move towards the fixing base 201. Through the cooperative transmission formed by the driving rack 502 and the driven gear 507, the laser scanning probe 506 on the lower side of the other end of the driven swing arm 505 rotates towards the test position directly above the caliper 304. Conversely, when the clamping and standing base 406 moves away from the fixing base 201 and the main rotating hexagonal column 203, the laser scanning probe 506 rotates away from the test position;

[0076] Thus, after the caliper 304 enters the position where it cooperates with the brake pad 208 and reaches the place, the laser scanning probe 506 can just rotate to the position directly above the friction plate of the caliper 304, forming the real-time scanning and monitoring work of the positional relationship between the friction plate of the caliper 304 and the outer surface of the brake pad 208. When not in test installation, the driven swing arm 505 and the laser scanning probe 506 will rotate to a position where they do not interfere with the installation of the brake pad 208 and the mating seat 204;

[0077] And the rotational movement formed by the driven swing arm 505 and the laser scanning probe 506 will not interfere with the rotational movement formed by the swing arm 302 driving the caliper 304;

[0078] One end of the auxiliary connecting arm 601 is fixedly connected to the top end of the inclined connecting rod 306, and the lamp panel 602 is installed and fixed at the other end of the auxiliary connecting arm 601;

[0079] With the rotation of the inclined connecting rod 306 driving the swing arm 302 and the caliper 304, it can synchronously drive the rotation of the auxiliary connecting arm 601 and the lamp panel 602, so that when the swing arm 302 is located at a position away from the brake pad 208, the lamp panel 602 is also located at a position away from the brake pad 208. After the swing arm 302 drives the caliper 304 to move to the position where it cooperates with the brake pad 208 and reaches the place, the lamp panel 602 can move to directly below the position where the caliper 304 cooperates with the brake pad 208. At this time, using the uniform brightness formed by the lamp panel 602 as the background can improve the accuracy of the laser scanning probe 506 scanning between the friction plate of the caliper 304 and the outer surface of the brake pad 208, and eliminate the adverse effects of the external environment on the scanning work of the laser scanning probe 506.
