[0002] In the braking system of a car, brake pads are the most critical safety parts, which determine the braking effect. Brake pads are generally composed of steel plates, adhesive heat insulation layers and friction blocks. The heat insulation layer is composed of non-heat-conducting materials for heat insulation. The friction blocks are composed of friction materials and adhesives. When braking, they are pressed on the brake disc and brake drum to produce friction, thereby achieving the purpose of vehicle deceleration and braking. During the manufacturing process of brake pads, drilling equipment is required to open reserved holes for later installation and positioning.

The brake pad drilling device that is easy to position can automatically feed and discharge, and is convenient for fixing the brake pad in position, with a simple structure and high efficiency. However, the above technical solution has the following problems: 1. The conveying of brake pads needs to be driven by cylinders, and the discharging of brake pads needs to be driven by electric telescopic rods. That is, the conveying and discharging of brake pads need to be equipped with separate driving accessories, and the number of driving accessories is large; 2. When clamping and positioning the brake pad, the two clamping plates on both sides of the conveying direction are driven by elastic devices with springs. In order to ensure that the brake pad is clamped in the center position, the spring coefficient needs to be highly consistent. However, there are individual differences between springs. As long as one of the springs is loose or damaged, the clamping stability of the brake pad is difficult to guarantee, thus affecting the drilling accuracy. 3. The cleaning of drilling waste requires forming a closed protective cover first, and then collecting it through a fan and a vacuum cleaner, which is a cumbersome process; In summary, there is an urgent need to provide a brake pad drilling and positioning device with a small number of driving accessories, good clamping stability, and simple waste cleaning.

[0013] The present invention provides a method for using a brake pad drilling positioning device, comprising the following steps: Step S100, initial state: the slide plate is located at the front end of the conveying channel, the support frame is located below the fixed plate, and the rotating plate is in an inclined state; Step S200, conveying state: the brake pad enters the conveying channel, the cylinder drives the support frame and the slide plate to move to the rear end of the conveying channel at the same time, the support frame moves to the bottom of the rotating plate and supports the rotating plate to enter the horizontal state, and the slide plate 3 pushes the brake pad into the clamping area. Step S300, clamping state: after the slide plate moves to the limit position, it clamps the brake pad from the front and rear ends together with the baffle plate, and the two side plates clamp the brake pad from both sides, the brake pad is fixed, and the brake pad is drilled by a drilling machine; Step S400, reset: after drilling is completed, the cylinder drives the support frame and the slide plate to move toward the front end of the conveying channel at the same time, the support frame enters from under the rotating plate to under the fixed plate, the rotating plate loses support and enters a tilted state, and the brake pad slides off the rotating plate.

[0014] Compared with the prior art, the present invention has the following beneficial technical effects: 1. The slide plate and the support frame are connected by an L-shaped connecting rod. Under the push of the cylinder, the support frame can enter under the rotating plate before the slide plate, so that the rotating plate enters a horizontal state under the support of the support frame. The slide plate pushes the brake pad into the clamping area to clamp the brake pad. After the drilling of the brake pad is completed by the drilling machine, the cylinder drives the support frame and the slide plate to move to the front end of the conveying channel at the same time. The support frame enters under the fixed plate from under the rotating plate. After the rotating plate loses support, it enters an inclined state, and the brake pad slides off the rotating plate for discharge. The present invention can realize the conveying, clamping and discharging of the brake pad only by one cylinder drive, and the amount of driving accessories is small; 2. The two side plates form a Y-shaped conveying channel, which makes it easier for the brake pads to enter. In the conveying section, the side plates will not clamp the brake pads, which can reduce the movement resistance of the brake pads in the conveying channel and avoid wear. Wear-resistant rubber is set in the clamping section to reduce wear, enhance the clamping effect, and also play a shock-absorbing role when drilling; 3. A roller is arranged on the top of the gantry to reduce the moving resistance of the support frame, and a sliding track is connected to the bottom to increase both the moving resistance and the moving stability of the support frame; 4. Side slides and springs are provided on both sides of the slide. The side slides and springs form a telescopic compensation structure. The side slides are always close to the inner wall of the side plate to prevent the brake pads from getting stuck in the gap between the slide and the side plate during the movement of the Y-shaped conveying channel. The rollers can reduce the movement resistance and protect the side wall from being scratched. 5. Both ends of the side plate are connected to the vertical plate and the baffle plate, which can improve the installation stability of the side plate. The first slider and the second slider slide with the first slide groove on the vertical plate and the second slider on the baffle plate. The width of the conveying channel can be adjusted by adjusting the distance between the two side plates to meet the conveying and clamping requirements of brake pads of different sizes and models; 6. The baffle is fixed on the drilling machine stand, which can make the whole drilling equipment compact. When the brake pad is clamped and fixed in the clamping area, the drill on the drilling machine stand can directly drill holes in the brake pad; the limit block on the drilling machine stand can limit the tilt angle of the rotating plate, so that the brake pad can directly slide into the collection box after the rotating plate is tilted; 7. Connect the push-pull rod on the slide plate to the piston rod of the air pump, and drive the air pump to inhale and deflate through the reciprocating movement of the slide plate. Use the airflow when the air pump deflates to purge the clamping area after drilling. The drilling slag on the brake pad will fall onto the rotating plate, and then fall from the hollow rotating plate into the waste chip box. The movement of the slide plate can realize the blowing and collection of the drilling waste chips, which is convenient and quick. 8. The air pump of the present invention has a simple structure and low manufacturing cost. The air pump realizes the suction and deflation of the purge chamber through the reciprocating motion of the piston. The purge chamber is directly connected to the clamping area through the air pipe. When the slide plate moves toward the clamping area, the air pipe inhales air. When the slide plate moves away from the clamping area, the air pipe deflates air to purge the clamping area. 9. The push-pull rod of the slide plate and the piston rod of the air pump can be connected by a buckle. When the push-pull rod moves toward the clamping area with the slider, the push-pull rod approaches the piston rod and can be buckled with the piston rod. After the buckle connection, the push-pull rod pushes the piston rod to extend, and the air pump inhales air. When the push-pull rod moves away from the clamping area with the slider, the push-pull rod first pulls the piston rod back, and the air pump deflates to purge the clamping area. When the piston rod retracts to the limit position, the push-pull rod continues to move and releases the buckle connection with the piston rod. Finally, the slide plate moves to the initial position, and the push-pull rod and the piston rod are spaced a certain distance apart. The above structural design can make the length of the piston rod smaller than the stroke of the slide plate, thereby reducing the overall length of the cylinder body, reducing the volume of the air pump, and reducing production costs. In summary, the brake pad drilling and positioning device provided by the present invention has a small number of driving accessories, good clamping stability, and simple waste cleaning.

Changes or adjustments to their relative relationships should be regarded as the scope of implementation of the present invention without substantially changing the technical content. Example 1

[0019] Combined with Figure 1-11 The present embodiment provides a brake pad drilling and positioning device, including a conveying platform 1, the conveying platform 1 includes a table top 11, the table top 11 is provided with two side plates 2 forming a conveying channel 10, the conveying channel 10 is provided with a slide plate 3 inside, and the rear end is connected to a baffle plate 4, the table top 11 includes a hinged fixed plate 111 and a rotating plate 112, a cylinder 16 and a support frame 5 are provided below the fixed plate 111, an L-shaped connecting rod 31 passing through the table top 11 and connected to the support frame 5 is provided at the bottom of the slide plate 3, the support frame 5 moves and supports the rotating plate 112 under the drive of the cylinder 16, the slide plate 3 moves at the same time, and forms a clamping area 20 together with the side plates 2, the baffle plate 4 and the rotating plate 112.

[0020] In the above technical scheme, the brake pad can enter the conveying channel 10 in any suitable manner. For example, a manipulator can be provided at the end of the brake pad conveying line, and the manipulator can grab the brake pad and put it into the conveying channel 10 of the brake pad drilling and positioning device, or the brake pad drilling and positioning device can be placed below the end of the brake pad conveying line so that the brake pad can fall directly from the conveying line into the conveying channel 10; the table 11 preferably has a uniform overall thickness, that is, when the rotating plate 112 enters a horizontal state, the upper and lower end surfaces of the fixed plate 111 and the rotating plate 112 are located in the same horizontal plane. Of course, since the table 11 serves as a conveying surface, when the rotating plate 112 is in a horizontal state, its upper end surface must be located in the same horizontal plane as the upper end surface of the fixed plate 111. This is common knowledge and will not be repeated here, but The lower end surface of the rotating plate 112 can be lower than the lower end surface of the fixed plate 111. At this time, the upper end surface of the support frame 5 does not contact the lower end surface of the fixed plate 111. When the support frame 5 moves to the bottom of the rotating plate 112, it can support the rotating plate 112 to rotate it to a horizontal state; the two side plates 2 can form a conveying channel 10 for the transfer of brake pads, and at the same time can provide clamping force from both sides to the brake pads. The slide plate 3 and the support frame 5 are connected by an L-shaped connecting rod 31. Under the push of the cylinder 16, the support frame 5 can enter under the rotating plate 112 before the slide plate 3, so that the rotating plate 112 enters a horizontal state under the support of the support frame 5; the cylinder 16 can be fixed on the conveying platform 1, or it can be fixed separately at any suitable position, and the baffle 4 can be fixed at the rear end of the conveying channel 10 in any suitable form.

[0021] In the initial state, the slide plate 3 is located at the front end of the conveying channel 10, the support frame 5 is located under the fixed plate 111, and the rotating plate 112 is in an inclined state. When in use, the brake pad enters the conveying channel 10, and the cylinder 16 drives the support frame 5 and the slide plate 3 to move toward the rear end of the conveying channel 10 at the same time. The support frame 5 moves to the bottom of the rotating plate 112 before the slide plate 3 and supports the rotating plate 112 to enter a horizontal state, and then the slide plate 3 pushes the brake pad into the clamping area 20, the slide plate 3 and the baffle plate 4 clamp the brake pad from the front and rear ends, and the two side plates 2 clamp the brake pad from both sides, and the brake pad is fixed. At this time, the brake pad can be drilled by a drilling machine. After drilling is completed, the cylinder 16 drives the support frame 5 and the slide plate 3 to move toward the front end of the conveying channel 10 at the same time, the support frame 5 enters from under the rotating plate 112 under the fixed plate 111, and the rotating plate 112 re-enters the inclined state after losing support, and the brake pad slides off the rotating plate 112.

[0022] In a specific technical solution, the side panel 2 includes a conveying section 21 and a clamping section 22. The two side panels 2 are symmetrically arranged to form a Y-shaped conveying channel 10. The inner wall of the clamping section 22 is provided with wear-resistant rubber 23; the support frame 5 includes a gantry 51. The top of the gantry 51 is provided with a roller 52 and the bottom is connected to a sliding rail 53.

[0023] In the above technical scheme, the side plate 2 forms a Y-shaped conveying channel 10, and the Y-shaped conveying channel 10 enables the brake pad to enter more easily. In the conveying section 21, the side plate 2 will not clamp the brake pad, which can reduce the movement resistance of the brake pad in the conveying channel 10 and avoid wear. Wear-resistant rubber 23 is arranged in the clamping section 22, which can reduce wear, enhance the clamping effect, and also play a shock-absorbing role when drilling; a roller 52 is arranged on the top of the gantry 51, which can reduce the movement resistance of the support frame 5, and the bottom is connected to a sliding track 53, which can not only increase the movement resistance of the support frame 5, but also improve the movement stability of the support frame 5.

[0024] In a specific technical solution, the table top 11 is provided with a long hole 12 that slides with the connecting rod 31, the lower end surface is provided with a supporting leg 13, the upper end surface is provided with a vertical plate 14 connected to the side plate 2, and the top of the vertical plate 14 is provided with a guide plate 15 inclined toward the conveying channel 10. In the initial state, the slide plate 3 is stored under the guide plate 15.

[0025] In the above technical solution, the long hole 12 and the connecting rod 31 are slidably matched, which means that the length of the long hole 12 is consistent with the stroke of the connecting rod 3, that is, the long hole 12 spans the fixed plate 111 and the rotating plate 112. Since the long hole 12 spans the fixed plate 111 and the rotating plate 112, the hinges of the fixed plate 111 and the rotating plate 112 should be located on both sides of the long hole 12 respectively to avoid interfering with the movement of the connecting rod 3. This is common knowledge and will not be repeated here. Since the L-shaped connecting rod 31 is divided into a vertical section and a horizontal section, it is consistent with the long hole 12. The hole 12 slides against the side wall of its vertical section, so it is preferred to set a ball there to reduce the movement resistance; the legs 13 can not only provide support for the table 11, but also be used for the installation and fixation of the cylinder 16. Of course, the cylinder 16 can also be fixed on the lower end surface of the fixed plate 111 or fixed alone at any other suitable position. In this embodiment, H-shaped legs 13 are set on both sides of the lower end surface of the fixed plate 111, and the cylinder 16 is horizontally installed between the two legs 13 through a fixing plate.

[0026] In a specific technical solution, the front end of the side panel 2 is provided with a first slider 25 and a first locking bolt 26, the rear end is provided with a second slider 27 and a second locking bolt 28, the vertical plate 14 is horizontally provided with a first slide groove 141 that cooperates with the first slider 25, and the baffle 4 is horizontally provided with a second slide groove 41 that cooperates with the second slider 27.

[0027] In the above technical solution, the two ends of the side panel 2 are connected to the vertical panel 14 and the baffle 4, which can improve the installation stability of the side panel 2. The first slider 25 and the second slider 27 slide with the first slide groove 141 on the vertical panel 14 and the second slider 27 on the baffle 4. The width of the conveying channel 10 can be adjusted by adjusting the distance between the two side panels 2 to meet the conveying and clamping requirements of brake pads of different sizes and models.

[0028] In a specific technical solution, grooves 33 are provided on both sides of the slide plate 3, and a side slide plate 34 is slidably provided in the groove 33. A spring 35 connected to the groove 33 is provided on the inner side of the side slide plate 34, and a roller 36 abutting against the inner wall of the side plate 2 is provided on the outer side.

[0029] In the above technical solution, the side slide 34 and the spring 35 form a telescopic compensation structure. The side slide 34 is always close to the inner wall of the side plate 2 to prevent the brake pad from being stuck in the gap between the slide 3 and the side plate 2 during the movement of the Y-shaped conveying channel 10. The roller 36 can reduce the movement resistance and protect the side plate 2 from being scratched.

[0030] In a specific technical solution, the baffle 4 is fixed on the drilling machine stand 6, and the side wall of the drilling machine stand 6 is provided with a limit block 61 for limiting the inclination angle of the rotating plate 112, and a collection box 7 docking with the inclined rotating plate 112 is provided below.

[0031] In the above technical solution, the drilling machine stand 6 is used to place a drilling machine (not shown in the figure), and the baffle 4 is fixed on the drilling machine stand 6, which can make the structure of the entire drilling equipment compact. When the brake pad is clamped and fixed in the clamping area 20, the drill on the drilling machine stand 6 can directly drill holes in the brake pad; the limit block 61 can limit the inclination angle of the rotating plate 112, so that the brake pad can directly slide into the collection box 7 after the rotating plate 112 is tilted.

[0032] In a specific technical solution, an air pump 8 is fixedly provided on the table top 11, and the air pipe 84 of the air pump 8 is connected to the clamping area 20. A push-pull rod 32 is provided on the upper end surface of the slide plate 3, and the push-pull rod 32 is connected to the piston rod 83 of the air pump 8. When the push-pull rod 32 moves away from the clamping area 20, the air pump 8 purges the clamping area 20. The rotating plate 112 is a hollow plate, and a waste box 9 is provided at the bottom.

[0033] In the above technical solution, the air pump 8 can directly adopt a commercially available product. The necessary components of the commercially available air pump 8 include a cylinder 81, a piston 82, a piston rod 83 and an air pipe 84. The air pump 8 is mainly used to inflate an elastic body such as a tire or a balloon. The suction and deflation actions can be achieved by pushing and pulling the piston rod 83. Since the slide plate 3 directly pushes the piston rod 83 of the air pump 8 to move, the air pump 8 is arranged in parallel with the conveying channel 10, so that the piston rod 83 and the slide plate 3 can work in coordination. This is common knowledge and will not be repeated here. In this embodiment, the slide plate 3 is The push-pull rod 32 on the upper part is connected to the piston rod 83 of the air pump 8, and the air pump 8 is driven to inhale and deflate by the reciprocating movement of the slide plate 3. The airflow when the air pump 8 is deflated is used to purge the clamping area 20 after the drilling is completed, and the drilling waste on the brake pad is blown onto the rotating plate 112, and then falls into the waste box 9 from the hollow rotating plate 112. The air pump 8, the slide plate 3 and the support frame 5 are driven by a common cylinder 16. The number of driving accessories used is small and the structure is compact. The drilling waste can be purged and collected by the movement of the slide plate, which is convenient and quick.

[0034] In a specific technical solution, the air pump 8 includes a sealed cylinder 81, and the piston 82 divides the interior of the cylinder 81 into a purge chamber and a piston rod chamber (not shown in the figure). The purge chamber is connected to the air pipe 84, and the piston rod chamber is provided with an air hole 811 and a piston rod 83 connected to the piston 82. The piston rod 83 slides through the cylinder 81 and extends toward the baffle 4. The cylinder 81 is arranged on the fixed plate 111 through a fixed seat 85.

[0035] In the above technical solution, the air pump 8 realizes the suction and deflation of the purge chamber through the reciprocating motion of the piston 82. The purge chamber is directly connected to the clamping area 20 through the air pipe 84. When the slide plate 3 moves toward the clamping area 20, the air pipe 80 inhales air. When the slide plate 3 moves away from the clamping area 20, the air pipe 80 deflates to purge the clamping area 20. Compared with the commercially available air pump 8, the air pump 8 in the present invention has a simple structure and low manufacturing cost.

[0036] In a specific technical solution, the length of the piston rod 83 is smaller than the stroke of the slide plate 3, the push-pull rod 32 is provided with a clamp 321, the piston rod 83 is provided with a fastener 831 which is snap-connected with the clamp 321, the air pump 8 has two of them, which are symmetrically arranged on the outer side of the side panel 2, and the side panel 2 is provided with a purge hole 24 which is connected with the air pipe 84.

[0037] In the above technical scheme, when the push-pull rod 32 moves with the slide plate 3 toward the clamping area 20, the push-pull rod 32 approaches the piston rod 83 and is snap-connected with the piston rod 83 under the action of induction. After the snap-connection, the push-pull rod 32 pushes the piston rod 83 to extend, and the air pump 8 inhales air. When the push-pull rod 32 moves with the slide plate 3 away from the clamping area 20, the push-pull rod 32 first pulls the piston rod 83 back, and the air pump 8 deflates to purge the clamping area 20. When the piston rod 83 retracts to the extreme position, the push-pull rod 32 continues to move, and is released from the snap-connection with the piston rod 83 under the action of tension. Finally, the slide plate 3 moves to the initial position, and the push-pull rod 32 and the piston rod 83 are spaced a certain distance apart. The above structural design can make the length of the piston rod 83 smaller than the stroke of the slide plate 3, thereby reducing the overall length of the cylinder 81, reducing the volume of the air pump 8, and reducing production costs. In this embodiment, the clamp 321 includes a round shaft connected to the push-pull rod 32, and an elastic ball head is fixed at the end of the round shaft. The fastener 831 includes a connecting plate vertically connected to the piston rod 83, and a plug hole matching the elastic ball head is provided on the connecting plate. The elastic ball head can be inserted into the plug hole under the action of thrust and detached from the plug hole under the action of tension. The diameter of the round shaft is consistent with that of the plug hole.
