Description

Technical Field

[0001] This invention relates to the field of brake pad processing technology, and more particularly to a drilling device for brake pad production. Background Technology

[0002] Automotive brake pads are friction materials fixed to brake drums or brake discs that rotate with the wheels. They are primarily composed of a brake pad steel backing and friction material bonded together using heat-sealing technology, and are used in automotive braking systems. The brake pad steel backing is mainly a fan-shaped carbon steel sheet, with several mounting holes on the large flat surface of the fan-shaped body and the arc surface at the top for positioning and fixing the friction material or brake pad.

[0003] In the existing technology, there are already drilling equipment on the market for drilling holes in the steel back of brake pads. Such equipment includes a drilling machine with two drill rod axes intersecting and a clamping mechanism for clamping the brake pads. The clamping mechanism includes a fixture for clamping the brake pads. Currently, there are many types of brake pads, but their thickness is usually 6mm. This means that various brake pads have different lengths and curvatures. To cope with this difference, different fixtures are required when processing different brake pads. Therefore, it is necessary to disassemble and replace the corresponding fixtures when processing different brake pads. The fixtures have a complex structure, which makes assembly and disassembly time-consuming and labor-intensive, thus affecting the efficiency of drilling a large number of brake pads.

[0004] Therefore, the present invention proposes a drilling device for brake pad production. Summary of the Invention

A pressure fixture located above the interior of the adjacent V-shaped clamping plates is fixedly connected to the top of the lever arms. A control mechanism is provided on the grooved plate for controlling the synchronous opposing and reversing movements of the two V-shaped clamping plates and the up-and-down movement of the V-shaped clamping plates.

[0007] As a further description of the above technical solution: The control mechanism includes a middle beam and a drive plate. The middle beam is located at the bottom of the channel plate and the two are slidably connected. The drive plate is located below the channel plate and one end of it is fixedly connected to one side of the middle beam. The bottom of the lifting plate is fixedly connected to a transmission shaft that passes through the channel plate. A roller located above the drive plate is provided in the transmission shaft. The top wall of the drive plate is provided with an inclined surface.

[0008] As a further description of the above technical solution: The control mechanism includes a limiting beam, a rotating shaft, connecting blocks, and connecting rods. The limiting beam is located between the lifting plate and the channel plate and is slidably connected to the channel plate. Connecting blocks are provided on both sides of the channel plate and are slidably connected to both ends of the limiting beam. Suspension plates are fixedly connected to both sides of the channel plate at one end. A rotating shaft is provided through the suspension plate. A lower rod is fixedly connected to the bottom end of the rotating shaft and rotatably connected to one side of an adjacent connecting block. An upper rod is fixedly connected to the top end of the rotating shaft. One end of the upper rod is hinged to one end of an adjacent lever arm through a connecting rod.

[0009] As a further description of the above technical solution: The control mechanism includes elastic telescopic pressure rods. Elastic telescopic pressure rods are provided on both sides of the channel plate. One end of the elastic telescopic pressure rod is hinged to one side of the intermediate beam, and the other end is hinged to the other side of the adjacent connecting block.

[0010] As a further description of the above technical solution: A locking cylinder is fixedly connected to the bottom of the intermediate beam, and the output shaft of the locking cylinder is fixedly connected to a friction disc located inside the groove plate. A brake plate located above the friction disc is fixedly connected to one side of the limiting beam.

[0011] As a further description of the above technical solution: The other end of the lever arm is fixedly connected to a guide sleeve. A small section of the V-shaped clamp is fixedly connected to a guide post sleeved in the guide sleeve via a slotted seat. A vertical shaft is welded to the top wall of the press. The top end of the vertical shaft is fixedly connected to the top wall of the guide sleeve via an L-shaped beam.

[0012] As a further description of the above technical solution: A support plate is fixedly connected inside the channel plate, near the top and located on one side of the lifting plate. A push plate is provided above the support plate, and the push plate and the support plate are slidably connected. Two clearance grooves are opened on the side of the lifting plate facing the channel plate, respectively near both ends. Two clearance notches are opened on the end of the support plate near the lifting plate, respectively opposite to the two clearance grooves. A push rod passing through the clearance notches is fixedly connected to the bottom end of the push plate.

[0013] As a further description of the above technical solution: One end of the pallet is provided with a slide between two clearance grooves. A slide plate is provided in the slide. The bottom wall of the push plate is fixedly connected to a connecting plate that is fixedly connected to one side of the slide plate. The bottom wall of the slide plate is fixedly connected to a transmission arm that passes through the groove plate.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. In this invention, a lifting plate, a V-shaped clamping plate, a lever arm, and a pressure fixture are provided. The lifting plate is used to support the brake pads. When the two V-shaped clamping plates move in opposite directions, their inner sidewalls can adaptively clamp brake pads of different specifications. When the lifting plate rises, the pressure fixture passively squeezes the brake pads. This configuration allows the drilling equipment to clamp brake pads of various specifications horizontally and vertically without changing the clamps. Compared with the prior art, this configuration saves replacement time, reduces labor intensity, and improves the efficiency of drilling.

[0015] 2. In this invention, a middle beam, a limiting beam, a driving beam, an inclined plane, an elastic telescopic pressure bar, a connecting block, a lever arm, a rotating shaft, and a connecting rod are provided. By controlling the movement of the middle beam, the brake pads placed on the lifting plate can be clamped horizontally first, and then reinforced vertically. Compared with the prior art, this linkage horizontal and vertical clamping structure of the brake pads greatly reduces the space occupied by the clamping structure, and also reduces the cost of the clamping structure.

[0016] 3. In this invention, by setting a locking cylinder, friction disc and brake plate, the limiting beam has a locking function relative to the intermediate beam. This setting enables the two V-shaped clamping plates, lifting plate and pressure fixture that clamp the brake pad to have a reliable anti-loosening function, and can effectively avoid the problem of vibration affecting the drilling accuracy when drilling the brake pad.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Example 1

[0021] Please see Figures 1-8A drilling device for brake pad production includes a conical loading platform 104, two machine bases 102 on both sides of the conical loading platform 104, a positioning table 1 on the machine base 102, a grooved plate 2 fixedly mounted above the positioning table 1, and two drilling machines 105 located behind the grooved plate 2 on the positioning table 1. The grooved plate 2 is used to support a clamping mechanism for clamping the brake pads. The drilling machines 105 are used to drill holes in the arc-shaped surface of the steel back of the brake pads. The distance between the two drilling machines 105 is adjustable and they can rotate. The drilling machines 105 have a feeding drilling function. By adjusting the distance between the two drilling machines 105 and then controlling the drilling machines 105 to rotate at a certain angle, holes and grooves at different positions can be formed on the steel back. In other words, when drilling the steel back of brake pads of different specifications, the position between the two drilling machines 105 can be adjusted. In this technical solution, the clamping mechanism included in the equipment has the function of drilling holes in the back of various brake pad steels with the same thickness but different shapes and specifications. When switching to process brake pads of different specifications, there is no need to change the clamping mechanism of other specifications, which greatly reduces the workload and improves the efficiency of drilling.

[0022] Specifically, a lifting plate 4 is provided near one end inside the groove plate 2. This lifting plate 4 is a positioning plate placed during the processing of brake pads. The top of the lifting plate 4 is slidably connected to two symmetrical V-shaped clamping plates 5. When the two V-shaped clamping plates 5 maintain a symmetrical state and move in opposite directions, they will clamp the brake pads placed flat on the lifting plate 4 horizontally and centered. It should be noted that the brake pads are curved standard parts. When the brake pads are clamped by the two V-shaped clamping plates 5, the two ends of the brake pads will press against the two side walls inside the V-shaped clamping plates 5 respectively. Therefore, the two V-shaped clamping plates 5 can reliably clamp the brake pads horizontally.

[0023] Furthermore, the opposing ends of the two V-shaped clamps 5 are slidably connected vertically to lever arms 6, which are slidably connected horizontally to the channel plate 2. In specific implementation, the other end of the lever arm 6 is fixedly connected to a guide sleeve 61. The small section of the V-shaped clamp 5 is fixedly connected to a guide post 51 fitted inside the guide sleeve 61 via a channel seat. The guide post 51 and the guide sleeve 61 are slidably connected vertically. The two sides of the channel plate 2 are fixedly connected to a suspension plate 21 located at one end. The top wall of the suspension plate 21 is welded to a support and fitted with a guide post 61. The limiting sleeve outside the lever arm 6 is slidably connected to the lever arm 6. The lever arm 6 connected by the two V-shaped clamps 5 is in a collinear state. The top of the lever arm 6 is fixedly connected to a pressure fixture 7 located inside and above the adjacent V-shaped clamps 5. Specifically, a vertical shaft 71 is welded to the top wall of the pressure fixture 7. The top end of the vertical shaft 71 is fixedly connected to the top wall of the guide sleeve 61 through an L-shaped beam 711. When the lifting plate 4 carries the brake pads on its upper part and moves up to a certain distance, the pressure fixture 7 will squeeze the brake pads onto the lifting plate 4. In summary, the two V-shaped clamps 5, together with the pressure fixture 7, ensure that the brake pads on the lifting plate 4 are fully clamped.

[0024] In this embodiment, the groove plate 2 is provided with a control mechanism 8 for controlling the synchronous opposite and reverse movement of the two V-shaped clamping plates 5 and the up and down movement of the V-shaped clamping plates 5. When it is necessary to clamp the brake pads on the lifting plate 4, the control mechanism 8 has the function of first controlling the two V-shaped clamping plates 5 to horizontally clamp the brake pads, and then sequentially controlling the lifting plate 4 to rise and vertically clamp the brake pads with the pressure fixture 7.

[0025] Specifically, the control mechanism 8 includes a middle beam 81 and a drive plate 82. The middle beam 81 is located at the bottom of the channel plate 2 and the two are slidably connected. Specifically, the middle beam 81 is channel-shaped, and guide posts are provided on both sides of the channel plate 2. The two ends of the guide posts are fixedly connected to the channel plate 2 through ear plates. A support sleeve is fixedly provided on the middle beam 81 and sleeved outside the guide posts. The support sleeve and the guide posts are slidably connected. The drive plate 82 is located below the channel plate 2 and one end of it is fixedly connected to one side of the intermediate beam 81. The drive plate 82 is perpendicular to the intermediate beam 81 and parallel to the channel plate 2. The bottom of the lifting plate 4 is fixedly connected to a transmission shaft 41 that passes through the channel plate 2. When the transmission shaft 41 moves up and down, it will drive the lifting plate 4 to move up and down. The bottom wall of the lifting plate 4 is fixedly connected to limit posts located on both sides of the transmission shaft 41. The limit posts are set through the bottom of the channel plate 2 and the two are slidably connected up and down. A roller 411 is set inside the transmission shaft 41 and located above the drive plate 82. The top wall of the drive plate 82 is provided with an inclined surface 821. Before the inclined surface 821 is processed, the drive plate 82 is rectangular. The setting of the inclined surface 821 makes a part of the drive plate 82 form a wedge shape. During the lateral movement of the drive plate 82, when the inclined surface 821 contacts the roller 411 and continues to move, the transmission shaft 41 will rise, thereby driving the lifting plate 4 to rise. In other words, when the drive plate 82 moves, it can control the lifting plate 4 to move up and down, thereby clamping and releasing the brake pads.

[0026] The control mechanism 8 includes a limiting beam 83, a rotating shaft 84, a connecting block 85, and a connecting rod 86. The limiting beam 83 is located between the lifting plate 4 and the channel plate 2 and is slidably connected to the channel plate 2. Connecting blocks 85 are provided on both sides of the channel plate 2 and are slidably connected to the two ends of the limiting beam 83, respectively. Specifically, rectangular sliding holes are opened on both sides of the channel plate 2, and the limiting beam 83 passes through the rectangular sliding holes. Sliding grooves are opened on the upper and lower sides of the rectangular sliding holes. Guide plates are fixedly installed on the upper and lower sides of the limiting beam 83 in the sliding grooves. The guide plates and the sliding grooves are slidably connected. A guide rod is fixedly installed on the connecting block 85, and guide holes that are slidably adapted to the guide rod are opened at both ends of the limiting beam 83. A pivot shaft 84 is installed through the suspension plate 21, meaning that the pivot shaft 84 and the suspension plate 21 are rotatably connected. A lower rod 841, with one end rotatably connected to one side of an adjacent connecting block 85, is fixedly connected to the bottom end of the pivot shaft 84. When the limiting beam 83 moves, it can drive the lower rod 841 to swing horizontally via the connecting block 85. An upper rod 842 is fixedly connected to the top end of the pivot shaft 84. When the lower rod 841 swings horizontally, it drives the upper rod 842 to swing horizontally via the pivot shaft 84. One end of the upper rod 842 is hinged to one end of an adjacent lever arm 6 via a connecting rod 86. When the upper rod 842 swings horizontally, it can drive the lever arm 6 to slide via the connecting rod 86. When the limiting beam 83 moves, it can drive the two V-shaped clamping plates 5 to move synchronously in opposite directions via the two lever arms 6. This achieves the left and right clamping and release of the brake pads.

[0027] As mentioned above, the control mechanism 8 has the function of sequentially controlling the horizontal and vertical clamping of the brake pads. Specifically, the control mechanism 8 includes an elastic telescopic pressure rod 87, which is a two-section telescopic structure with an internal compression spring. The two ends of the compression spring are free ends. That is, when the elastic telescopic pressure rod 87 extends to a certain length, the compression spring is in a free state. When the elastic telescopic pressure rod 87 retracts to a certain length, the compression spring is compressed. Elastic telescopic pressure rods 87 are provided on both sides of the groove plate 2. One end of the elastic telescopic pressure rod 87 is hinged to one side of the intermediate beam 81, and the other end is hinged to the other side of the adjacent connecting block 85. When the intermediate beam 81 moves towards the limiting beam 83, the intermediate beam 81 will apply an elastic thrust to the limiting beam 83 through the elastic telescopic pressure rod 87. During this process, the elastic telescopic pressure rod 87 will experience free extension and contraction with resistance. The resistance to the contraction is provided by the limiting beam 83.

[0028] The driving force required for the movement of the intermediate beam 81 is provided by the electric telescopic rod. In specific implementation, a frame is welded to the bottom wall of the channel plate 2, and the frame and the electric telescopic rod are fixedly connected. The output shaft of the electric telescopic rod is fixedly connected to the intermediate beam 81.

[0029] Since the clamping force of the two V-shaped clamping plates 5 on the brake pads is provided by the elastic pressure of the elastic telescopic pressure rod 87, there is a potential risk that the clamping force of the V-shaped clamping plates 5 on the brake pads is unreliable. Therefore, a locking cylinder 101 is fixedly connected to the bottom of the intermediate beam 81. The output shaft of the locking cylinder 101 is fixedly connected to the friction disc 1011 located in the groove plate 2. A brake plate 831 located above the friction disc 1011 is fixedly connected to one side of the limiting beam 83. When the locking cylinder 101 drives the friction disc 1011 to move upward and squeeze the brake plate 831, the limiting beam 83 and the intermediate beam 81 are in a relatively fixed state under the action of the friction force generated by the squeezing. At this time, the V-shaped clamping plates 5 clamping the brake pads are in a fixed state.

[0030] In this embodiment, a support plate 22 is fixedly connected inside the channel plate 2, near the top and located on one side of the lifting plate 4. A push plate 9 is provided above the support plate 22, and the push plate 9 and the support plate 22 are slidably connected. The function of the push plate 9 is to push the brake pad placed on the support plate 22 onto the lifting plate 4. Two limiting strips for limiting the movement of the brake pad are welded to the upper end face of the support plate 22. The two limiting strips are used to limit the movement of the brake pad. Two clearance grooves 42 are opened on the side of the lifting plate 4 facing the channel plate 2, respectively near the two ends. Two clearance notches 222 are opened on the end of the support plate 22 near the lifting plate 4, respectively opposite to the two clearance grooves 42. A push rod 91 is fixedly connected to the bottom end of the push plate 9, passing through the clearance notch 222. When the push rod 91 enters the clearance groove 42 from the clearance notch 222, the push rod 91 will push the brake pad in front of it to the top of the lifting plate 4 and to the position between the two V-shaped clamps 5. It should be noted that in its natural state, the upper surface of the lifting plate 4 is slightly lower than the upper surface of the support plate 22, for example, by 0.5-1mm. This arrangement allows the brake pads that have been drilled and placed on the lifting plate 4 to be pushed away from the lifting plate 4 by the next brake pad to be drilled, which is pushed by the push plate 9.

[0031] In this embodiment, a slide 223 is provided at one end of the support plate 22 between two clearance grooves 42. A slide plate 2231 is provided in the slide 223. A connecting plate 92 is fixedly connected to the bottom wall of the push plate 9 on one side and fixedly connected to one end of the slide plate 2231. A transmission arm 22311 with a gap passing through the channel plate 2 is fixedly connected to the bottom wall of the slide plate 2231. When the transmission arm 22311 moves, it will push the push plate 9 to move through the slide plate 2231. In use, a control cylinder is fixedly connected to the bottom wall of the channel plate 2 through a support plate. The output shaft of the control cylinder is fixedly connected to one side of the transmission arm 22311. The control cylinder provides driving force to the movement of the transmission arm 22311.

[0032] The equipment also includes a crossbeam located above the two machine bases 102. A movable control base 103 is mounted on the crossbeam, and a transfer cylinder is mounted on the movable base 103. A suction cup assembly is fixedly installed on the actuating end of the transfer cylinder. When the movable base moves, it can move the suction cup assembly to above the tray 22 and above one of the hoppers of the conical loading platform 104. This arrangement facilitates automatic feeding of the brake pads. The conical loading platform 104 is rotatable; when it rotates, it can move one of the hoppers to the material-picking position of the suction cup assembly. It should be noted that because the hopper is tilted, the brake pads inside are in a tilted stacked state. Therefore, the transfer cylinder can also be tilted, which facilitates reliable suction of the brake pads by the suction cup assembly. The movable control base, control cylinder, suction cup assembly, and conical loading platform 104 are all electrically connected to the control box of this equipment. The control box has a built-in controller (PLC) that controls the operation of the equipment according to a built-in program.

[0033] Working principle: When drilling is required for the brake pads, the brake pads are placed on one of the support plates 22 and positioned between the two limit strips. Then, the push plate 9 is moved, pushing the brake pads to slide on the support plate 22. When the brake pads are pushed onto the lifting plate 4, they are positioned between the two V-shaped clamps 5, with both ends of the brake pads facing the inner grooves of the V-shaped clamps 5. Then, the push plate 9 is retracted, and the intermediate beam 81 is moved towards the limit beam 83. When the elastic telescopic pressure rod 87 is under pressure, it pushes the connecting block 85 with its elastic force. The movement of the connecting block 85 causes the corresponding lower rod 841 to swing. The swinging of the lower rod 841 causes the upper rod 842 to swing via the rotating shaft 84. The swinging of the upper rod 842 then... Link 86 pushes the lever arm 6 to move. When the two lever arms 6 move in opposite directions, the two V-shaped clamps 5 will move in opposite directions. When the two V-shaped clamps 5 are close together, they will guide and clamp the brake pads using their two inner side walls. In other words, the brake pads will be self-clamped by the two V-shaped clamps 5 using their respective inner side walls. When clamped, the inclined surface 821 on the drive plate 82 begins to contact the roller 411. As the intermediate beam 81 continues to move, the inclined surface 821 will apply a pushing force to the roller 411. The transmission shaft 41 drives the lifting plate 4 to rise. When the upper end face of the brake pad abuts against the pressure fixture 7, the intermediate beam 81 is controlled to stop moving. At this time, the brake pad is in the position to be drilled. Then, the two drilling machines 105 on this equipment are controlled to feed to drill holes in the steel back of the clamped brake pad. After the brake pads are drilled, the intermediate beam 81 is controlled to move in the opposite direction. At this time, the distance between the two V-shaped clamps 5 increases, and the lifting plate 4 will descend. The processed brake pads are in a free position. Then, the push plate 9 is controlled to move and push the brake pads to be drilled in front of it towards the lifting plate 4. The brake pads to be drilled push the processed brake pads away from the lifting plate 4. At this time, the brake pads to be drilled are on the lifting plate 4. Then, the equipment is restarted to perform drilling. This cycle is repeated to achieve sequential drilling of a large number of brake pads.

[0034] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
