Description

Technical Field

[0001] The invention relates to the technical field of disc brake pad preparation, and in particular to a disc brake pad preparation system. Background Art

[0002] Disc brakes are one of the most common braking systems on modern cars and other vehicles. Compared with drum brakes, they have better heat dispersion, better water resistance and more stable friction performance. They are generally composed of a brake disc fixed on the wheel hub and a brake caliper clamped on both sides of the brake disc. When working, the brake caliper pushes the brake pads against the brake disc to slow down or stop the vehicle. The quality of the brake pads directly affects the braking effect of the brakes. Therefore, the product quality must be strictly controlled during the preparation process of the brake pads.

[0003] At present, the production of disc brake pads includes BP treatment, pre-pressing, thermoforming, heat treatment and post-processing. Among them, thermoforming and heat treatment are the key steps in the preparation process and have a significant impact on the quality of the brake pads. When performing thermoforming and heat treatment, equipment such as curing furnaces or ovens are generally used to complete the operation. In actual operation, the staff will place the pre-pressed brake pads evenly in the curing furnace, and then fix them with a clamp. However, in the large-scale production process, the number of brake pads processed each time is large. It will take a lot of time to manually fix the brake pads one by one. In addition, many brake pads will be stationary in the curing furnace, which will cause uneven heat distribution and affect the overall processing effect. In order to improve work efficiency and the overall processing effect, it is necessary to use heat treatment equipment that can fix the workpiece and drive it to rotate during the processing.

[0004] After searching, the patent document with publication number CN101818237B discloses a steel pipe clamping and rotating device, including a frame, on which relative roller seats are provided, on which rollers with adjustable height and center distance are fixed, and the rollers are rotated by a driving motor, and above the rollers on the frame are provided a pressure roller for pressing the steel pipe, and a support wheel group for auxiliary supporting the steel pipe is arranged at a distance from the frame.

[0005] The above-mentioned steel pipe clamping and rotating device can fix the workpiece and drive it to rotate, but has the following shortcomings:

[0006] Different driving devices are required for the fixation and rotation of the workpiece, which increases the production cost. In addition, due to the high working environment temperature, the driving equipment is easily damaged in a high temperature environment, resulting in insufficient overall processing stability. In addition, the workpiece can only rotate on its own. When a single workpiece is heat treated, the overall heating can be guaranteed to be uniform. However, when more workpieces are processed at the same time, due to the uneven overall temperature distribution inside the device, it is difficult to ensure that all workpieces are heated evenly. Therefore, it is necessary to design a preparation system for disc brake pads. Summary of the invention

[0007] In view of the deficiencies in the prior art, the present invention provides a system for preparing a disc brake pad, which solves the problems raised in the above-mentioned background technology.

[0017] Furthermore, a swing groove is provided on the side wall of the taking groove, and a rotating shaft is rotatably installed in the swing groove, a mounting rod is fixedly installed on the rotating shaft, and the mounting rod is fixedly connected to the box door.

[0018] Furthermore, a receiving groove matched with the arc-shaped tooth plate is provided on the inner wall of the box body, and two movable grooves are provided on the side wall of the receiving groove, and fixed racks are installed in both movable grooves for forward and backward sliding.

[0019] Furthermore, the opening and closing switching assembly consists of an installation groove, a fixed gear ring, a screw and a connecting rod.

[0025] 3: Through the design of the opening and closing switching component, the position of the arc-shaped tooth plate and the fixing rod in the box body can be automatically adjusted by the opening and closing action of the box door. Therefore, the fixing action and the rotation action of the brake pad can be automatically switched according to the actual processing steps, which can not only ensure the stability of the brake pad during the fixed treatment, but also ensure that the rotation treatment is not disturbed, making the action switching of the entire heat treatment process more ingenious and natural.

[0026] In summary, the present invention, through clever structural coordination, can use the rotation of the rotating rod during the placement of the brake pad to automatically fix the brake pad in sequence, and use the rotation of the brake pad during the heat treatment process to evenly distribute the heat in the box.

[0036] Reference Figure 1 - Figure 8 A preparation system for a disc brake pad includes a housing 1 and a plurality of brake pads 4. The brake pads 4 are made of high-performance fiber composite materials, resin, metal fiber, graphite and talcum powder. The high-performance fiber composite materials are one or more of carbon fiber, aramid fiber and ceramic fiber. Studies have shown that each friction of asbestos-type brake pads will generate millions of asbestos fibers and emit them into the air. After these asbestos fibers are inhaled into the human body, they will cause irreversible lung fibrosis, gradually causing the patient's alveoli to lose function and leading to respiratory system failure. In addition, due to the long-term stimulation of the fine asbestos fibers, they may also induce respiratory malignant tumors such as lung cancer. Therefore, the use of high-performance fiber composite materials to replace the traditional asbestos in the brake pads 4 can effectively avoid the harm of the needle-shaped fibers in the asbestos to the human body. At the same time, the mechanical properties of the high-performance fiber composite materials under high temperature and high pressure environments are more stable.

[0037] A preparation system for a disc brake pad also includes a box door 3, a box body 1 is provided with a taking slot 2, the box door 3 is rotatably installed in the taking slot 2, the box door 3 is used to control the switch of the taking slot 2, a swinging slot is provided on the side wall of the taking slot 2, and a rotating shaft 16 is rotatably installed in the swinging slot, a mounting rod 15 is fixedly installed on the rotating shaft 16, and the mounting rod 15 is fixedly connected to the box door 3, the mounting rod 15 cooperates with the rotating shaft 16, so that the box door 3 can rotate in the taking slot 2, when it is in Figure 1 In the state shown, the taking slot 2 is opened, and the staff can place or take the brake pad 4 at this time. A handle is fixedly installed on the box door 3, and a sealing strip matching the taking slot 2 is fixedly installed at one end of the box door 3 away from the mounting rod 15. When the box door 3 is closed, the design of the sealing strip can effectively reduce the heat loss in the box body 1.

[0038] The motor is fixedly installed at the bottom of the box body 1, and the output end of the motor is fixedly connected to a rotating rod 5 that passes through the bottom of the box body 1. A plurality of supporting legs are fixedly installed at the bottom of the box body 1, and the height of each supporting leg is greater than the height of the motor. The motor can specifically adopt a DC motor commonly used in daily life and work. When the motor is working, it can drive the rotating rod 5 to rotate in the box body 1.

[0039] A heat source is installed in the box 1, and a controller 23 is fixedly installed on the side wall of the box 1, and the controller 23 is electrically connected to the heat source and the motor. The heat source is an existing product that can generate heat through electricity. Its working principle and specific structure are not elaborated here. The controller 23 can specifically adopt a KV-16AT model controller, which is used to control the working conditions of the motor and the heat source.

[0040] A plurality of positioning components are rotatably mounted on the rotating rod 5, and the positioning components are used to fix and shape the brake pad 4. The positioning components include a support rod 6 rotatably mounted on the rotating rod 5, a bottom clamping plate 7 is fixedly mounted on the support rod 6, and a fastening mechanism matching the brake pad 4 is mounted on the bottom clamping plate 7. The fastening mechanism is composed of a top clamping plate 8, a side support frame 9, a slide groove 10, a slider 11, a screw rod and a fixed gear 12;

[0041] The side support frame 9 is fixedly mounted on the side wall of the end of the bottom clamping plate 7 away from the support rod 6, the slide groove 10 is opened on the side support frame 9, the slider 11 is slidably mounted in the slide groove 10 up and down, the top clamping plate 8 is fixedly mounted on the slider 11, and the top clamping plate 8 corresponds to the bottom clamping plate 7 up and down, the screw rod is rotatably mounted on the side support frame 9, and the end of the screw rod located in the slide groove 10 is threadedly connected to the slider 11, the fixed gear 12 is fixedly mounted on the end of the screw rod located outside the side support frame 9, and the fixed gear 12 cooperates with the arc-shaped toothed plate 13. When the screw rod rotates, the top clamping plate 8 can be driven by the slider 11 to move up and down relative to the bottom clamping plate 7, so that the distance between the two can be adjusted, thereby realizing the fixing or releasing of the brake pad 4, and the fixed gear 12 is installed on the top of the screw rod and used as the rotation driving end of the screw rod.

[0042] When the brake pad 4 is fixed between the bottom clamp plate 7 and the top clamp plate 8, the starting motor can drive the brake pad 4 to rotate horizontally in the box body 1 through the rotating rod 5, or when the motor is powered off, the staff can also manually rotate the rotating rod 5 to make the brake pad 4 rotate horizontally in the box body 1. Therefore, when placing or taking multiple brake pads 4, a corresponding number of brake pads 4 can be placed on multiple bottom clamp plates 7 close to the side of the taking slot 2 first, and then the rotating rod 5 is rotated to make the other bottom clamp plates 7 without brake pads 4 placed rotate to the taking slot 2 in turn, so as to realize the placement or taking of all brake pads 4 on the corresponding bottom clamp plates 7.

[0043] The transmission part is used for transmitting the multiple support rods 6. The transmission part includes a fixed rod 19 which is installed in the box body 1 for sliding up and down. A lifting rod is fixedly installed on the top of the fixed rod 19. A lifting groove which cooperates with the lifting rod for sliding up and down is provided on the top inner wall of the box body 1. The lifting rod and the lifting groove are both rectangular, which can limit the horizontal angle of the fixed rod 19 in the box body 1 and allow the fixed rod 19 to slide up and down in the box body 1. A through hole which cooperates with the fixed rod 19 is provided on the rotating rod 5. The design of the through hole can prevent the rotating rod 5 from interfering with the up and down sliding of the fixed rod 19.

[0044] The fixing rod 19 is fixedly installed with multiple active bevel gears 20 in sequence from top to bottom, and one end of each support rod 6 located in the through hole is fixedly installed with a driven bevel gear 18, and each active bevel gear 20 is matched with the corresponding multiple driven bevel gears 18. When the fixing rod 19 moves downward in the box body 1, the multiple active bevel gears 20 thereon move downward at the same time and mesh with the corresponding driven bevel gears 18 respectively. Then, the position of the fixing rod 19 is fixed and the rotating rod 5 is rotated. The meshing effect of the active bevel gear 20 and the driven bevel gear 18 can be utilized to make the brake pad 4 rotate horizontally in the box body 1 while rotating around the center line of the support rod 6 as the center point. At this time, not only can the multiple brake pads 4 be heated more evenly, but the rotation effect can also be used to stir the gas in the box body 1, so that the heat distribution inside the box body 1 is even, effectively ensuring that the multiple brake pads 4 are heated evenly as a whole, thereby improving product quality.

[0045] The clamping drive unit is used to drive multiple fastening mechanisms. The clamping drive unit includes an arc-shaped toothed plate 13 slidably mounted on the inner wall of the box body 1. A receiving groove that matches the arc-shaped toothed plate 13 is provided on the inner wall of the box body 1, and two movable grooves are provided on the side wall of the receiving groove. Fixed racks 14 are slidably mounted in both movable grooves. The front end of the movable groove is not intercommunication with the inner wall of the box body 1. Under the cooperation of the fixed rack 14 and the movable groove, not only the movement of the arc-shaped toothed plate 13 can be controlled, but also the movement of the arc-shaped toothed plate 13 can be controlled. The arc-shaped toothed plate 13 is driven in a row, and the connection effect of the arc-shaped toothed plate 13 on the accommodating groove can be ensured. When the arc-shaped toothed plate 13 extends outward in the accommodating groove, the straight-line distance between it and the center line of the box body 1 is equal to the straight-line distance between the end of the fixed gear 12 away from the rotating rod 5 and the center line of the box body 1. At this time, the rotation of the rotating rod 5 can make the fixed gear 12 contact with the arc-shaped toothed plate 13 and rotate relative to it. Therefore, under the meshing effect of the two, the lead screw can be driven to rotate, thereby automatically adjusting the distance between the top splint 8 and the bottom splint 7.

[0046] An opening and closing switching component is installed on the box door 3. The opening and closing switching component adjusts the positions of the fixed rod 19 and the arc-shaped toothed plate 13 in the box body 1 according to the opening and closing conditions of the box door 3. The opening and closing switching component consists of a mounting groove, a fixed gear ring 17, a screw 22 and a connecting rod 21. The mounting groove is arranged between the swing groove and the accommodating groove. The fixed gear ring 17 is fixedly mounted on the upper and lower ends of the rotating shaft 16, and the two fixed gear rings 17 are respectively meshed with the two fixed racks 14. The screw 22 is fixedly mounted on the upper end of the rotating shaft 16. The connecting rod 21 is fixedly mounted on the side wall of the lifting rod, and the connecting rod 21 is threadedly connected to the screw 22.

[0047] Combination Figure 1 as well as Figure 8Taking the top view direction as an example, when the box door 3 is opened, the rotating shaft 16 rotates counterclockwise, at this time, the fixed gear ring 17 pushes the fixed rack 14 to move left, so that the arc-shaped toothed plate 13 protrudes outward from the accommodating groove, and at the same time, the counterclockwise rotation of the rotating shaft 16 causes the lead screw 22 to rotate counterclockwise at the same time, so that the connecting rod 21 moves up and drives the fixed rod 19 to move up, so that the multiple active bevel gears 20 and the corresponding multiple driven bevel gears 18 are separated from each other, and then the staff places the brake pad 4 and pushes the rotating rod 5 to rotate one circle in the box body 1 in the counterclockwise direction. In this process, the multiple fixed gears 12 contact and mesh with the arc-shaped toothed plate 13 in turn, so that the multiple top clamping plates 8 automatically move down to complete the fixation of the multiple brake pads 4. After rotating the rotating rod 5 one circle, the brake pad 4 is placed on each bottom clamping plate 7, and each brake pad 4 is effectively fixed;

[0048] After the placement and fixation of multiple brake pads 4 are completed, the box door 3 is closed. At this time, the rotating shaft 16 rotates clockwise, driving the arc-shaped toothed plate 13 to move to the accommodating groove and intersect with the fixed gear 12. At the same time, the screw 22 rotates clockwise to move the connecting rod 21 downward. When the box door 3 is completely closed, the fixed rod 19 also drives the multiple active bevel gears 20 to mesh with the corresponding multiple driven bevel gears 18 respectively. Then, the temperature in the box body 1 is controlled by the controller 23, the motor switch is controlled, and the processing time is set. As the motor runs, the rotating rod 5 rotates to drive the multiple brakes The brake pads 4 rotate horizontally in the box body 1. At the same time, since the driven bevel gear 18 and the active bevel gear 20 are in a meshing state, multiple brake pads 4 will also rotate during the rotation of the rotating rod 5, thereby stirring the airflow in the box body 1 to keep the internal temperature uniform, thereby ensuring that all brake pads 4 can be heated evenly and ensuring the overall product quality. When the processing is completed, wait until the temperature in the box body 1 cools to room temperature, open the box door 3, and rotate the rotating rod 5 clockwise for one circle. During the rotation process, multiple brake pads 4 are released one by one, and the staff can take out the released brake pads 4 one by one.
