Description

Technical Field

[0001] The present invention relates to the technical field of brake pad processing, and in particular to a brake pad grooving processing device and a use method thereof. Background Art

[0002] In the braking system of a car, brake pads are the most critical safety parts. The quality of all braking effects is determined by the brake pads. In order to improve the heat dissipation performance of the brake pads, it is often necessary to groove the brake pads.

[0003] The prior art mostly adopts a brake pad slotting device such as the one disclosed in the announcement number CN212239435U, which cools down the brake pad and the cutting knife during the cutting work by washing with water. Another example is a brake pad slotting machine disclosed in CN220782457U, in which a rotating mechanism for rotating the outer clamping block is provided at the bottom of the processing table, which can fix the two ends and the top of the brake pad, improve the fixing effect of the brake pad, and prevent the displacement of the brake pad during slotting: However, the water flushing method adopted above is only a simple point-touch clamping method. The flushing and rotating operations can easily cause impact on the brake pad, causing it to loosen and move. It is difficult to effectively fix the brake pad during the grooving operation, and it is impossible to ensure that the grooving parts can be accurately docked with the brake pad, which will seriously affect the grooving accuracy. At the same time, the above technology has the following defects in practical application: Fig.12 -Attached Fig.14 In the prior art, the types of grooves opened on brake pads include single-groove structure, double-groove structure and triple-groove structure. In the above technology, when grooving the brake pad, only single-groove processing can be performed on the brake pad. In order to meet diverse usage requirements, existing brake pads will have multiple groove structures. The existing grooving machines either cannot be adjusted accordingly according to the requirements of opening double grooves and triple grooves of the brake pads, or the position and state of the brake pads need to be frequently adjusted, which makes it difficult to effectively position the brake pads, making it impossible for the device to accurately groove the double-groove brake pads or triple-groove brake pads.

Since the sliding plate is in conflict with the limit frame and the connecting block is rotationally connected to the hollow shaft, the sliding plate is not affected by the rotation of the hollow shaft. Step S4, starting the first electric slide rail to drive the second electric slide rail to drive the first motor to move forward and backward, and the first motor drives the first cutting piece to move forward and backward through the hollow shaft, so as to perform a single groove cutting operation on the brake pad, and at this time, the second cutting piece does not contact the brake pad; Step S5, the hollow rotating shaft drives the connecting block to move forward and backward, the connecting block drives the sleeve to move forward and backward, the sleeve drives the movable rod to move forward and backward, because the sliding plate and the limiting frame are in a state of conflict at this time, the sliding plate is not pulled by the movable rod, and the movable rod drives the movable block to move forward and backward in the limiting long hole, stretching the third spring so that the bracket on the sliding plate is not affected by the horizontal movement of the hollow rotating shaft, avoiding the positions of the rotating plate, the first clamping plate and the second clamping plate on the brake pad from being affected by the horizontal movement of the hollow rotating shaft to move, thereby ensuring that when the first cutting piece is performing a cutting operation, the limiting mechanism can cooperate with the limiting frame to ensure the stability of the brake pad during the grooving process; Step S6, when two grooves need to be opened on the brake pad, start the second motor to drive the cam to rotate, and use the sliding connection between the elliptical ring groove and the connecting slider to make the two sliding brackets move in the opposite direction under the influence of the position difference generated during the rotation of the cam, and the two sliding brackets drive the two second electric slide rails to move in the opposite direction through the two first electric slide rails, and the two second electric slide rails drive the two first motors to move in the opposite direction, and the two first motors drive the two hollow shafts to move in the opposite direction on the two mounting shafts, and the hollow shaft drives the second cutting piece to move in the opposite direction on the two mounting shafts, and the second cutting piece drives one end of the traction rod to move linearly, and the other end of the traction rod drives the first cutting piece to move linearly, and the first cutting piece drives the telescopic rod to shrink the structure, so that the first cutting piece is stored between the two second cutting pieces, and executes steps S1-step S5; Step S7, when three grooves need to be opened on the brake pad, execute step S6, so that the horizontal end points of the first cutting piece and the two second cutting pieces are in the same horizontal plane, and execute steps S1 to S5; Step S8, after the groove of the brake pad is completed, the second electric slide rail is started, the second electric slide rail drives the first motor to move vertically upward, the first motor drives the hollow rotating shaft to move vertically upward, the hollow rotating shaft drives the limiting mechanism and the slotting mechanism to move vertically upward, the sliding plate and the limiting frame are separated, and under the elastic force of the third spring, the movable block is reset in the sliding plate, the sliding rod and the resistance rod are movably resisted, the hollow rotating shaft continues to move upward, the resistance rod limits the height position of the sliding rod, the sliding rod moves vertically downward in the storage slide groove, squeezing the first spring, the sliding rod drives the squeezing rod to move vertically downward, the squeezing rod squeezes the movable rod, the movable rod is forced to move downward, so that the card rod moves outward under the force of the movable rod moving downward, the card rod stretches the second spring, and when the movable rod is away from the card rod, the card rod is reset under the elastic force of the second spring, and the movable rod is reset under the action of gravity.

[0015] Compared with the prior art, the present invention has the following advantages: 1. In the present invention, by using a first cutting piece and two second cutting pieces whose working states can be adjusted, when the two second cutting pieces are received in the first cutting piece, the slotting mechanism performs single-groove processing on the brake pad; when the first cutting piece is received between the two second cutting pieces, the slotting mechanism performs double-groove processing on the brake pad; when the highest end points of the first cutting piece and the second cutting piece are in a horizontal plane, the slotting mechanism performs triple-groove processing on the brake pad. Compared with the prior art which requires replacement of cutting components of different specifications, the present technical solution can realize slotting operations on brake pads with different slotting requirements by adjusting the states of the first cutting piece and the two second cutting pieces, which helps to improve the applicability and flexibility of the processing device.

[0016] 2. In the present invention, the vertical movement of the first cutting member can be guided by the telescopic rod, and the stability of the second cutting member during horizontal movement is ensured by the sliding connection between the mounting shaft and the hollow rotating shaft.

[0017] 3. In the present invention, a limiting mechanism is used to fix and limit the brake pad. When the second clamping plate abuts against the brake pad, the second clamping plate is rotated by the slope of the upper surface of the brake pad, so that the second clamping plate can rotate accordingly according to the change of the slope of the brake pad surface, which helps to improve the applicability and flexibility of the limiting mechanism for the brake pad. When the groove opening mechanism performs groove opening operation on the brake pad, the brake pad is horizontally limited by the limit frame, and the brake pad is vertically limited by the limit mechanism, which helps to ensure the stability of the brake pad during the groove opening process.

[0018] 4. In the present invention, the movable block can move horizontally in the guide long hole, and the elastic force of the third spring is used to enable the movable block to be reset when not pulled. The horizontal sliding of the movable block can avoid the position change of the limiting mechanism when the first cutting member and the second cutting member move horizontally, so that the limiting position of the brake pad by the limiting mechanism remains unchanged, which helps to ensure the limiting effect of the limiting mechanism on the brake pad.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Refer to the instruction manual Fig.12 -Attached Fig.14 The above figures show three types of slotting for brake pads. This technical solution can perform three numbers of slotting operations on brake pads: Reference Figure 1-Figure 11 A brake pad slotting processing device includes a machine tool body 1 for processing a brake pad, and the machine tool body 1 is provided with a sliding bracket 2, a second motor 9, an adjustment mechanism driven by the second motor 9, a first electric slide rail 3, a second electric slide rail 4, a limit frame 5, an avoidance groove 6 corresponding to the slotting position of the brake pad, a first motor 7, a hollow shaft 8, a limit mechanism and a slotting mechanism, and the components are arranged as follows: The sliding bracket 2 is slidably mounted on the left and right ends of the machine tool body 1. The machine tool body 1 is provided with long guide holes that run left and right and are used for sliding the sliding bracket 2. The sliding bracket 2 can be guided and limited through the long guide holes, so that the sliding bracket 2 can only move towards and in the opposite direction in the left and right directions due to the restriction of the long guide holes. A moving roller is arranged at the bottom end of the sliding bracket 2. The setting of the moving roller helps to reduce the friction force generated by the contact between the sliding bracket 2 and the ground, and the machine tool body 1 is supported by the sliding bracket 2 to further ensure the stability of the machine tool body 1.

[0023] The second motor 9 is fixedly mounted on the machine tool body 1 , and the adjusting mechanism is arranged at the lower end of the machine tool body 1 , and the adjusting mechanism is used to drive the sliding bracket 2 to move and adjust horizontally to the left and right.

[0024] A further implementation method is that the adjustment mechanism includes a cam 10, an elliptical ring groove 11 and a connecting slide block 12 fixedly connected to the sliding bracket 2, and each component is arranged as follows: The cam 10 is fixedly mounted on the output end of the second motor 9, and the cam 10 is an elliptical cross-section structure.

[0025] An elliptical annular groove 11 is provided on the cam 10, and a connecting slider 12 is slidably mounted in the elliptical annular groove 11. The connecting slider 12 is guided and limited by the elliptical annular groove 11, so that the connecting slider 12 can only move based on the opening trajectory of the elliptical annular groove 11, and the connecting slider 12 is fixedly connected with the sliding bracket 2, so that the connecting slider 12 is restricted by the guiding long hole and can only perform linear motion in the left and right directions. Since the cam 10 and the elliptical annular groove 11 are both elliptical cross-section structures, a position difference will be generated during the rotation of the cam 10. The position difference generated during the rotation of the cam 10 is used to drive the connecting slider 12 to perform linear motion in the left and right directions, thereby realizing the left and right movement adjustment of the sliding bracket 2 fixedly connected to the connecting slider 12 in the horizontal direction.

[0026] The first electric slide rail 3 is fixedly connected to the upper surface of the sliding bracket 2 , the second electric slide rail 4 is fixedly connected to the first electric slide rail 3 , and the first electric slide rail 3 is used to drive the second electric slide rail 4 to move and adjust forward and backward in the horizontal direction.

[0027] The limit frame 5 is fixedly connected to the upper surface of the machine tool body 1, and the shape structure of the limit frame 5 is set corresponding to the shape structure of the brake pad. The limit frame 5 can be used to limit the brake pad in the horizontal direction, which helps to avoid the horizontal position deviation of the brake pad. The avoidance groove 6 is opened on the machine tool body 1, and the groove width of the avoidance groove 6 is at least three times the groove width of the brake pad groove body. Through the setting of the avoidance groove 6, the grooving mechanism can be prevented from causing damage to the machine tool body 1 during operation.

[0028] The first motor 7 is fixedly mounted on the second electric slide rail 4 , and the first motor 7 is driven by the second electric slide rail 4 to move and adjust in the vertical direction. The hollow shaft 8 is mounted on the output end of the first motor 7 through a coupling.

[0029] The limiting mechanism is rotatably mounted on the hollow rotating shaft 8 , and is used for limiting the contact of the brake pad in the limiting frame 5 .

[0030] The further implementation method is that the limiting mechanism includes a connecting block 13, a sleeve 14, a receiving slide groove 15, a sliding rod 16, a first spring 17, an extrusion rod 18, a contact rod 19, a clamping rod 20, a second spring 21, a movable rod 22, a clamping groove 23, a sliding plate 24, a limiting long hole 25, a movable block 26, a third spring 27, a bracket 28, a rotating plate 29, a first clamping plate 30, a second clamping plate 31 and a limiting frame 32, and each component is arranged as follows: The connecting block 13 is rotatably mounted on the hollow rotating shaft 8 , and the sleeve 14 is fixedly connected to the lower end of the connecting block 13 .

[0031] The storage slot 15 is opened on the sleeve 14, the sliding rod 16 is slidably mounted in the storage slot 15, and the first spring 17 is welded between the storage slot 15 and the sliding rod 16. Through the setting of the first spring 17, the sliding rod 16 can be reset by the elastic force of the first spring 17 when not squeezed, and the squeezing rod 18 is fixedly connected to one end of the sliding rod 16 located in the sleeve 14.

[0032] The abutment rod 19 is fixedly connected to the second electric slide rail 4, and the abutment rod 19 movably abuts against one end of the sliding rod 16 away from the sleeve 14. By setting the abutment rod 19, the height position of the sliding rod 16 is limited, and the sliding rod 16 cannot continue to rise after rising to a certain height.

[0033] The clamping rod 20 is slidably mounted on the sleeve 14. The clamping rod 20 is located at one end of the sleeve 14 and is a triangular structure. The second spring 21 is welded between the sleeve 14 and the clamping rod 20. Through the elastic force of the second spring 21, the clamping rod 20 can be reset when not squeezed.

[0034] The movable rod 22 is slidably mounted in the sleeve 14, and the movable rod 22 is an L-shaped structure. A slot 23 is provided on the movable rod 22, and the clamping rod 20 is arranged corresponding to the slot 23. The slot 23 is a triangular slot structure arranged corresponding to one end of the clamping rod 20 located in the sleeve 14, and magnets are arranged on the end faces of the clamping rod 20 and the slot 23. Through the arrangement of the magnet, the clamping rod 20 is more stable after entering the slot 23, which helps to ensure the stability of the movable rod 22 in the sleeve 14.

[0035] The sliding plate 24 is arranged below the movable rod 22, and a limiting long hole 25 is opened on the sliding plate 24. The movable block 26 is slidably mounted in the limiting long hole 25. The limiting long hole 25 can provide a movable space for the movable block 26, and the movable block 26 is fixedly connected to the movable rod 22. The third spring 27 is welded to one end of the limiting long hole 25 away from the movable block 26. The elastic force of the third spring 27 is utilized to enable the movable block 26 to be reset when it is not pulled by the movable rod 22.

[0036] The bracket 28 is fixedly connected to the sliding plate 24, the rotating plate 29 is rotatably installed on the bracket 28, the first clamping plate 30 is rotatably installed on the rotating plate 29, and two first clamping plates 30 are provided, the second clamping plate 31 is rotatably installed on the first clamping plate 30, and the number of second clamping plates 31 on each first clamping plate 30 is two, the rotating plate 29, the first clamping plate 30 and the second clamping plate 31 are all hemispherical structures, and the second clamping plate 31 is rotatably installed so that the second clamping plate 31 can rotate under force to adapt to the different slopes of the upper surface of the brake pad.

[0037] When the second clamping plate 31 contacts the brake pad, the clamping rod 20 enters the clamping slot 23, and utilizes the magnetic attraction of the two magnets to further improve the connectivity between the clamping rod 20 and the clamping slot 23, which helps to ensure the vertical stability of the second clamping plate 31 when it is used to limit the brake pad.

[0038] When the card slot 23 needs to be separated from the card rod 20, the sliding rod 16 cannot continue to move upward due to the restriction of the resistance rod 19, but the sleeve 14 continues to move vertically upward driven by the second electric slide rail 4, so that the sliding rod 16 moves vertically downward relative to the sleeve 14 in the storage slide groove 15, and the sliding rod 16 drives the extrusion rod 18 to squeeze the movable rod 22, so that the movable rod 22 moves downward, so that the card slot 23 and the card rod 20 are separated by force.

[0039] The limiting frame 32 is fixedly connected to the machine tool body 1 , and the limiting frame 32 and the sliding plate 24 are movably opposed to each other. The limiting frame 32 is an L-shaped structure.

[0040] When the second clamping plate 31 and the brake pad are in active contact, the sliding plate 24 and the limit frame 32 are in active contact, so that when the first electric slide rail 3 drives the limit mechanism and the slotting mechanism to move horizontally, due to the sliding connection between the movable block 26 and the sliding plate 24, the movable rod 22 will drive the movable block 26 to move horizontally, and the movable block 26 moves horizontally in the sliding plate 24 for motion compensation, thereby avoiding the horizontal position of the second clamping plate 31 fixedly connected to the sliding plate 24 in the front and rear direction when the first electric slide rail 3 is started. It helps to ensure that the limiting effect of the second clamping plate 31 on the brake pad remains unchanged.

[0041] The slotting mechanism is fixedly connected to the hollow rotating shaft 8, and the slotting mechanism is used to perform fixed-point cutting on the brake pad in the limit frame 5; Further implementation method is that the slotting mechanism includes a mounting shaft 33, a mounting ball 34, a telescopic rod 35, a first cutting member 36, a second cutting member 37 and a traction rod 38, and each component is arranged as follows: The mounting shaft 33 is slidably mounted in the hollow rotating shaft 8. A guide slider is fixedly connected to the inner wall of the hollow rotating shaft 8. A guide slot for slidingly mounting the guide slider is provided on the mounting shaft 33. The guide slot can be used to guide and limit the guide slider, which helps to ensure the stability of the hollow rotating shaft 8 when it moves on the mounting shaft 33. The mounting ball 34 is fixedly connected to the mounting shaft 33. The telescopic rod 35 is fixedly connected to the mounting ball 34, and the first cutting member 36 is fixedly connected to the telescopic rod 35. At least five first cutting members 36 are arranged equidistantly around the circumference. The telescopic rod 35 provides a guide limit for the radial movement of the first cutting member 36, which helps to ensure that the first cutting member 36 can move radially on the same horizontal plane. The second cutting piece 37 is fixedly connected to the hollow rotating shaft 8, and two second cutting pieces 37 are provided. The first cutting piece 36 and the second cutting piece 37 are arranged concentrically. The two ends of the traction rod 38 are pin-connected to the first cutting piece 36 and the second cutting piece 37 respectively. The position difference generated when the two ends of the traction rod 38 perform linear motion is used to drive the first cutting piece 36 to perform radial motion.

[0042] The driving mechanism drives the two hollow rotating shafts 8 to move toward or in the opposite direction through the two sliding brackets 2, so as to adjust the position state of the first cutting member 36 and the second cutting member 37. The first cutting member 36 and the second cutting member 37 will find the following state during the adjustment process.

[0043] When the highest end point of the second cutting member 37 is lower than the highest end point of the first cutting member 36, the first cutting member 36 is involved in the work, and the second cutting member 37 is not involved in the work. At this time, the slotting mechanism can only process a single slot on the brake pad; When the highest end point of the second cutting piece 37 is higher than the highest end point of the first cutting piece 36, the first cutting piece 36 does not work, and the two second cutting pieces 37 work. At this time, the slotting mechanism can only perform double-groove processing on the brake pad.
