Description

TECHNICAL FIELD

[0001] The application relates to the milling technical field, in particular to a brake pad end face slotting device. BACKGROUND

[0002] The brake pad milling slotting is to make the brake pad quickly discharge the dust and debris generated in the braking process, increase the contact area of the friction end face and the air, speed up the heat dissipation, avoid the heat recession of the brake pad due to high temperature, guarantee the braking stability, and also make the brake pad better drain water and oil and better bite.

[0003] At present, the brake pad milling slotting operation is mostly carried out by using a numerical control milling machine or a special end face milling device, and a preset slot type is processed on the surface of the brake pad friction material by the rotary cutting motion of a milling cutter. The linear slot is a type commonly used at present. However, the existing milling device can only realize single-side slotting of the brake pad. In the conventional processing procedure, the brake pad is first fixed by a clamping fixing mechanism, and then the single-side slotting operation is completed by a conveying mechanism under the milling device. The back plate and the friction layer of the brake pad need to be slotted. If double-side processing is to be completed, the brake pad needs to be manually or mechanically turned over and then clamped and fixed again for the second milling slotting. The single-side processing and twice clamping and turning over mode not only increases the time cost of the process steps and clamping positioning, but also is prone to errors due to repeated positioning, which seriously restricts the overall processing efficiency and is difficult to adapt to the large-scale and high-efficiency production demand. Therefore, the application provides a brake pad end face slotting device to meet the demand. SUMMARY

[0044] like Figure 1 , Figure 2 and Figure 4As shown, an embodiment of the present invention provides a brake pad end face grooving processing device, including a milling processing device body 1, a first motor 2 mounted on the top of the milling processing device body 1, a milling cutter drive mechanism 3 mounted on the top of the milling processing device body 1, a milling cutter body 4 mounted on the milling cutter drive mechanism 3, a second motor 5 mounted on the top of the milling processing device body 1, a screw body 6 fixedly connected to the output end of the second motor 5, a first guide frame 7 mounted on the bottom of the screw body 6, a first movable block 8 mounted on the first guide frame 7, and a brake pad body mounted on the top of the first movable block 8. 26; Limiting and fixing mechanism, which is used to fix the brake pad body 26, and is connected to the first movable block 8; Tilting auxiliary mechanism, which is used to tilt the brake pad body 26, and is connected to the milling processing device body 1. The above-mentioned milling processing device body 1, first motor 2, milling cutter drive mechanism 3, milling cutter body 4 and second motor 5 are all existing mature technologies. Their working principles and specific structures will not be described in detail here. Among them, the output end of the first motor 2 is provided with a screw, and the bottom of the milling cutter drive mechanism 3 is equipped with a moving part. The moving block has a threaded sleeve inside, which can be fitted onto the screw at the output end of the first motor 2. The main body 1 of the milling machine forms the entire milling worktable. The function of the first motor 2 is to drive the milling cutter drive mechanism 3 to move, and the milling cutter drive mechanism 3 can adjust the lateral and longitudinal positions of the milling cutter body 4. By utilizing the coordinated cooperation between the above structures, the milling cutter body 4 can be flexibly adjusted to any position in the top space of the milling machine main body 1, thereby facilitating the opening of the brake pad body 26 placed on the top of the milling machine main body 1 by the milling cutter body 4. Milling process: During the milling of the brake pad body 26, this device can quickly and stably install the brake pad body 26 on the first movable block 8 through the limiting and fixing mechanism, thereby ensuring the stability of the milling cutter body 4 when performing milling operations on the brake pad body 26. In addition, by using the combination of the flipping mechanism and the limiting and fixing mechanism, the brake pad body 26 can be quickly flipped, so that both sides of the brake pad body 26 can be efficiently milled and slotted. This not only greatly improves work efficiency, but also has the advantages of simple operation and convenient use. The overall practicality of the device is good.

[0045] like Figures 3 to 10 and Figure 13As shown, the limiting and fixing mechanism includes a first connecting frame 9 mounted on a first movable block 8, a second guide frame 10 mounted on the top of the first connecting frame 9, a second movable block 11 mounted on the top of the second guide frame 10, a first connecting piece 13 fixedly connected to one side of the second movable block 11, a second connecting frame 14 fixedly connected to the side of the first connecting piece 13 away from the second movable block 11, a second connecting piece 15 fixedly connected to the side of the second connecting frame 14 away from the second movable block 11, a rotating shaft 16 mounted on the top of the second connecting piece 15, and a rotating shaft 16 mounted on the side of the rotating shaft 16 away from the second connecting piece 15. A third connecting piece 17 is provided, and a bracket 18 is fixedly connected to the side of the third connecting piece 17 near the second movable block 11. A first limiting frame 21 is fixedly connected to the top of the bracket 18. A third motor 12 is installed on one side of the second guide frame 10, and a bidirectional screw is installed at the output end of the third motor 12. A movable slot is opened at the top of the second guide frame 10, and a movable block is installed in the slot. The movable block is connected to the second movable block 11, and a screw sleeve is provided inside the movable block. The screw sleeve is fitted onto the bidirectional screw at the output end of the third motor 12. The function of the third motor 12 is to drive the second movable block 11 to move. Two second movable blocks 11 are provided, respectively arranged on both sides of the top of the second guide frame 10. The second guide frame 10 consists of two sets. One set of the second guide frame 10 has a first limiting frame 21 installed on its top, and the other set has a second clamping frame 37 installed on its top. The shape of the second clamping frame 37 matches the shape of the brake pad body 26. The structures at the top of the two sets of second guide frames 10 are identical except for the difference between the first limiting frame 21 and the second clamping frame 37. The two sets of second guide frames 10 and all structures above them are symmetrically installed on the milling machine. The top of the main body 1 of the milling device; when in use, the brake pad body 26 can be placed on the top of one of the second guide frames 10 by means of a gripping mechanism, or it can be placed manually; after placement, the third motor 12 on the top of one of the second guide frames 10 is started, and the two second movable blocks 11 on the top of the second guide frame 10 will move closer to each other, driving the first limiting frame 21 installed on its top to move closer together, and finally the two first limiting frames 21 clamp and fix the brake pad body 26, and place the brake pad body 26 in the central axis position of the main body 1 of the milling device;Then, the first motor 2 and the milling cutter drive mechanism 3 are started, and the position of the milling cutter body 4 is adjusted. The milling cutter body 4 is used to mill and groove one side of the brake pad body 26. After the grooving operation on this side is completed, the brake pad body 26 is taken out between the two first limiting frames 21. After the flipping operation is completed, it is placed between the two second clamping frames 37 on the top of another second guide frame 10. Then, the third motor 12 on the second guide frame 10 is started, so that the two second movable blocks 11 on its top move closer to each other, driving the two second clamping frames 37 to clamp the brake pad body 26. Then, the above milling and grooving operation process is repeated to complete the milling and grooving operation on the other side of the brake pad body 26. Through the coordinated cooperation of the above structures, the brake pad body 26 can be quickly and stably clamped and fixed, thus providing convenience for precise milling and grooving and effectively ensuring the quality of grooving. For the specific operation of flipping the brake pad body 26, please refer to the following detailed description.

[0046] Furthermore, the brake pad body 26 is typically composed of a back plate and a friction layer. The shapes and contours of the back plate and the friction layer are not entirely consistent. The shape of the first limiting frame 21 is adapted to the shape of the back plate of the brake pad body 26, and the shape of the second clamping frame 37 is adapted to the shape of the friction layer of the brake pad body 26. This ensures that the brake pad body 26 can remain stable during double-sided milling and grooving, thereby ensuring efficient and accurate milling operations. The first connecting piece 13 and the second connecting frame 14 form a triangular structure. Triangles have good stability and can provide good support for the second connecting piece 15. The second connecting piece 15 is inclined and consistent with the bottom contour of the second connecting frame 14. The third connecting piece 17 and the bracket 18 are integrally formed. Integral structures have good stability and are convenient for production and use. The bracket 18 has equidistant openings. A first lightweight groove 19 is provided to reduce the weight of the bracket 18. The shape of the bracket 18 is adapted to the shape of the brake pad body 26, so that the bracket 18 can stably support the brake pad body 26. The shape of the first limiting frame 21 is adapted to the shape of the brake pad body 26, so that the two first limiting frames 21 can stably clamp and fix the brake pad body 26. A first guide plate 22 is provided on one side of the first limiting frame 21, and a second lightweight groove 23 is provided on the side of the first limiting frame 21 away from the first guide plate 22, which reduces the weight of the first limiting frame 21. A guide part 24 is provided on the side of the first limiting frame 21 near the second lightweight groove 23. With the guidance of the first guide plate 22 and the guide part 24, the brake pad body 26 placed on the top of the second guide frame 10 can be quickly clamped and fixed between the two first limiting frames 21.

[0047] like Figures 1 to 6 and Figures 10 to 13As shown, the third connecting piece 17 has a connecting part 20 on the side away from the second movable block 11. The flipping auxiliary mechanism includes a support frame 27 installed on the main body 1 of the milling machine. The top two sides of the support frame 27 are fixedly connected to the second limiting frame 32. The top of the second limiting frame 32 has a recess 33 that matches the shape of the connecting part 20. The second limiting frame 32 has an inclined part 34. The first movable block 8 has a screw sleeve inside, which is fitted on the screw body 6. The shape of the first guide frame 7 matches the shape of the first movable block 8. The first guide frame 7 is used to limit and guide the movement trajectory of the first movable block 8. The second motor 5 is used to drive the first movable block 8 to move. The screw body 6 is a bidirectional screw. Two first movable blocks 8 are installed on one screw body 6. The two first movable blocks 8 are symmetrically installed on both sides of the screw body 6. First, the third motor 12 is started, so that the two first limiting frames 21 loosen the brake pad body 26, which only plays a limiting role and does not The clamps are tightened, and the distance between the two support frames 27 is slightly greater than the width of the brake pad body 26. Then the second motor 5 is started, which can drive the two first movable blocks 8 to move closer or further away. The second motor 5 drives the first movable blocks 8 to move, which can make the two second guide frames 10 move closer to each other, thereby pushing the third connecting piece 17 to move towards the support frame 27. When the connecting part 20 is close to the recess 33, it will be limited by the second limiting frame 32 on the third connecting piece 17, causing the third connecting piece 17 to rotate along the guide of the inclined part 34 and about the axis of the rotating shaft 16. When the third connecting piece 17 rotates, it will drive the bracket 18 and its various structures to rotate synchronously, thereby driving the brake pad body 26 to rotate. When the two third connecting pieces 17 move synchronously, the first limiting frame 21 and the second clamping frame 37 gradually approach each other. The third connecting piece 17 at the bottom of the first limiting frame 21 contacts the second limiting frame 32 as a rigid limit, so that the first limiting frame 21 will change angle first.A weakening portion 39 is provided on a second limiting frame 32 near the second clamping frame 37. The second limiting frame 32 is made of plastic. When the third connecting piece 17 on this side contacts the second limiting frame 32, the second limiting frame 32 will deform preferentially from the weakening portion 39. Therefore, the angle change of the third connecting piece 17 on this side is relatively slow. Finally, as the first limiting frame 21 approaches the supporting frame 27, the first limiting frame 21 presents an inclination angle slightly greater than 90 degrees, while the second clamping frame 37 presents an inclination angle slightly less than 90 degrees. At this time, the brake pad body 26 can be delivered from the first limiting frame 21 to the second clamping frame 37. On the holding frame 37, the second motor 5 is driven to rotate in the opposite direction, causing the second clamping frame 37 to rotate in the opposite direction and pulling the brake pad body 26 down together. The first limiting frame 21 rotates back into position, thus completing the flipping action of the brake pad body 26. Then, the third motor 12 is started to control the two second clamping frames 37 to move closer to each other and clamp the brake pad body 26. The cooperation between the above structures enables the brake pad body 26 to achieve efficient flipping and limiting fixation, thereby ensuring the working efficiency of double-sided milling and grooving of the brake pad body 26 and making the entire milling operation process smoother, which is convenient for the production and use of the brake pad body 26. Furthermore, a torsion spring is provided in the rotating shaft 16, so that the first limiting frame 21 tends to move closer to the second guide frame 10 in its natural state. The torsion spring is an existing mature technology, and its working principle and specific structure will not be described in detail here. When the third connecting piece 17 rotates, causing the first limiting frame 21 and the second clamping frame 37 to tilt, the torsion spring will deform. Therefore, when the second motor 5 rotates in the opposite direction, after the third connecting piece 17 gradually releases the restriction imposed by the second limiting frame 32, the deformation and elasticity of the torsion spring will cause the third connecting piece 17 to return to its original position.

[0048] Furthermore, after the brake pad body 26 is clamped and fixed by the second clamping frame 37, it can be milled and slotted by the milling cutter body 4. After the operation is completed, the brake pad body 26 can be automatically removed by the clamping mechanism or manually removed by the operator. The device has a feeding station and a unloading station. When the second motor 5 drives the two second guide frames 10 to move away from each other, the first limiting frame 21 and the second clamping frame 37 will correspond to the two stations respectively, so as to realize the linkage operation of synchronous feeding and unloading, thereby ensuring the working efficiency of the entire milling process.

[0049] Furthermore, the cross-section of the second limiting frame 32 is C-shaped, and the cross-sectional shape of the structure formed by the two second limiting frames 32 is close to V-shaped, which facilitates the use of it to form a limiting block on the third connecting piece 17, thereby realizing the flipping of the brake pad body 26. A second guide piece 38 is provided on one side of the second clamping frame 37, and a limiting part 25 is provided on the other side of the second clamping frame 37. By using the guide of the sliding groove 28, the brake pad body 26 can be quickly placed between the two second clamping frames 37. By using the support of the limiting part 25, the brake pad body 26 can be quickly received from the first limiting frame 21 into the second clamping frame 37.

[0050] like Figures 1 to 6 and Figures 10 to 13 As shown, the top two sides of the support frame 27 are provided with sliding grooves 28. A slider 29 is slidably connected in the sliding groove 28. A connecting rod 30 is fixedly connected to the side of the slider 29 away from the support frame 27. A sleeve block 31 is fixedly connected to the side of the connecting rod 30 away from the slider 29. A bellows 35 is installed in the sleeve block 31. The dust collection mechanism body 36 is installed at the bottom of the bellows 35. The milling cutter body 4 is driven to move by the coordinated control of the first motor 2 and the milling cutter drive mechanism 3. When the milling cutter body 4 approaches and pushes the connecting rod 30, it can drive the slider 29 to move inside the sliding groove 28, thereby realizing the position adjustment of the sleeve block 31. The adjustable position of the sleeve 31 allows for precise control of the top opening position of the bellows 35 installed inside. This ensures that waste chips and dust generated during milling and grooving operations on different positions of the brake pad body 26 by the milling cutter body 4 can be efficiently removed. The dust collection mechanism body 36 is a mature existing technology, and its working principle and specific structure will not be elaborated here. At the same time, the bellows 35 and the dust collection mechanism body 36 are configured in two sets, respectively corresponding to the back plate layer and friction layer of the brake pad body 26 for waste collection. This can effectively distinguish waste materials of different materials, thereby facilitating subsequent waste recycling and reuse.

[0051] Furthermore, the sleeve 31 has anti-slip texture inside, which can make the bellows 35 more stably installed in the sleeve 31. The cross-section of the slider 29 and the slide groove 28 are both T-shaped, so that the slider 29 can slide stably in the slide groove 28 without the problem of accidental detachment.

[0052] The working principle of the technical solution provided by this invention is as follows:

[0053] In use, the brake pad body 26 is first placed on top of one of the second guide frames 10 by means of a gripping mechanism or manual operation. Then, the third motor 12 on top of the second guide frame 10 is started, driving the two second movable blocks 11 to move closer to each other, which in turn drives the first limiting frame 21 on top to move closer together. Finally, the two first limiting frames 21 clamp and fix the brake pad body 26, and position the brake pad body 26 at the central axis position of the milling machine body 1.

[0054] Then, the first motor 2 and the milling cutter drive mechanism 3 are started, and the position of the milling cutter body 4 is adjusted. The milling cutter body 4 is used to mill and groove one side of the brake pad body 26. Then, the third motor 12 is started to loosen the brake pad body 26 with the two first limiting frames 21, which only play a limiting role and do not clamp it. At the same time, the distance between the two supporting frames 27 is slightly larger than the width of the brake pad body 26. Then, the second motor 5 is started, and the second motor 5 drives the bidirectional screw body 6 to rotate, which in turn drives the two first movable blocks 8 sleeved on it to move closer. The first guide frame 7 plays a limiting and guiding role on the movement trajectory of the first movable blocks 8.The movement of the first movable block 8 causes the two second guide frames 10 to move closer to each other, pushing the third connecting piece 17 towards the support frame 27. When the connecting part 20 on the third connecting piece 17 is pressed against the recess 33, it will be limited by the second limiting frame 32, causing the third connecting piece 17 to rotate along the guide of the inclined part 34 and about the axis of the rotating shaft 16. The rotation of the third connecting piece 17 causes the bracket 18 and the brake pad body 26 on it to rotate synchronously. Among them, the third connecting piece 17 at the bottom of the first limiting frame 21 is in rigid contact with the second limiting frame 32, so that the first limiting frame 21 will change its angle first. The second limiting frame 32 near the second clamping frame 37 is plastic. The material is reinforced with a weakening portion 39. When the third connecting piece 17 on this side contacts the second limiting frame 32, the second limiting frame 32 will deform preferentially from the weakening portion 39, resulting in a slower angle change of the third connecting piece 17 on this side. Ultimately, the first limiting frame 21 will have an inclination angle slightly greater than 90 degrees, and the second clamping frame 37 will have an inclination angle slightly less than 90 degrees, forming a natural delivery slope. The brake pad body 26 is then delivered from the first limiting frame 21 to the second clamping frame 37, and then the second motor 5 is driven to rotate in the opposite direction, causing the second clamping frame 37 to rotate and pulling the brake pad body 26 down. At the same time, the rotating shaft 16 is equipped with a torsion spring, which can allow the brake pad body 26 to descend in a natural state. The first limiting frame 21 tends to move closer to the second guide frame 10. When the third connecting piece 17 rotates, the torsion spring deforms and stores elastic potential energy. When the second motor 5 rotates in the opposite direction and the third connecting piece 17 gradually releases the limiting force of the second limiting frame 32, the deformation and elasticity of the torsion spring will cause the third connecting piece 17 and the first limiting frame 21 to automatically return to their original positions. Finally, the third motor 12 is started to control the two second clamping frames 37 to move closer to each other, clamping and fixing the flipped brake pad body 26. The milling cutter body 4 is used to mill and groove the other side of the brake pad body 26 clamped by the second clamping frames 37 after flipping. After the operation is completed, the brake pad body 26 can be automatically removed by the clamping mechanism. The sheet body 26 can also be manually removed by the operator. The device is equipped with a feeding station and a unloading station. When the second motor 5 drives the two second guide frames 10 to move away from each other, the first limiting frame 21 and the second clamping frame 37 will correspond to the two stations respectively, thereby realizing the linkage operation of synchronous feeding and unloading, improving the overall processing efficiency. Furthermore, the milling cutter body 4 is driven to move by the coordinated control of the first motor 2 and the milling cutter drive mechanism 3. When the milling cutter body 4 approaches and pushes the connecting rod 30, it can drive the slider 29 to move inside the slide groove 28, thereby adjusting the position of the sleeve block 31, and then precisely controlling the top opening position of the corrugated pipe 35 installed inside the sleeve block 31.The waste chips and dust generated during the milling process can be efficiently removed by the bellows 35. The bellows 35 and the main body of the dust collection mechanism 36 are set in two groups, respectively corresponding to the back plate layer and friction layer of the brake pad body 26 for waste collection, realizing the effective differentiation of waste materials of different materials, which is convenient for subsequent recycling and reuse. The structure of this device is relatively simple and easy to use and operate.
