Abstract
Description
Technical Field
[0001] This utility model relates to the field of brake pad manufacturing technology, and in particular to a highly integrated flexible post-processing unit for drum brake pads. Background Technology
[0002] The production of drum brake pads requires multiple machining processes, including grinding, drilling, and chamfering of the outer and inner curved surfaces, the sides and ends of the curved surface, as well as other machining operations. In existing technologies, each machining process for drum brake pads is performed separately and independently. This post-processing of brake pads not only requires multiple machines and occupies a large area, but also makes it difficult to ensure continuous production, significantly reducing production efficiency.
[0003] Although CN118848767A discloses a combined grinding machine for inner and outer arcs of drum brake pads, which can perform combined grinding of the inner and outer arcs and sides of brake pads, and CN220217880U discloses a forming machine for the end face and outer arc surface of drum brake pads, which can perform processing of the end face and outer arc surface of brake pads; other existing technologies also disclose processing equipment and combined grinding machines for brake pads, but the disclosed existing technologies can only perform processing of brake pads in several or more processes. To complete all the processing of brake pads, brake pads still need to undergo multiple transfers and conveying operations. After conveying, manual operation of feeding and other operations is required. It still cannot solve the problems of low production efficiency, difficulty in ensuring production continuity, large footprint, and high labor intensity of workers. Utility Model Content

[0007] Furthermore, when the outer arc rough grinding mechanism or the drilling mechanism is located in the middle of the post-processing unit, the input end of the outer arc rough grinding mechanism or the drilling mechanism is provided with a first flip-type feeding mechanism.
[0008] Furthermore, the input end of the conveying track is provided with a first hook, one end of which is rotatably connected to the conveying track near the input end, and the other end is provided with a compression spring between it and the conveying track.

[0010] Furthermore, the output end of the drilling mechanism is provided with a second flipping mechanism for flipping the brake pads 180°.
[0011] Furthermore, a mechanical gripper is provided above the fixing device of the fine grinding outer arc mechanism. The mechanical gripper is used to grab the brake pad on the input end of the fine grinding outer arc mechanism and place the brake pad on the horizontal rotating hub. After the brake pad is processed on the horizontal rotating hub, the mechanical gripper grabs the brake pad on the horizontal rotating hub and places the brake pad on the conveying unit at the output end of the fine grinding outer arc mechanism.
[0012] Furthermore, a one-way movable baffle is provided above the conveying track. The lower end of the one-way movable baffle is lower than the upper surface of the brake pad above the conveying track.

The workpiece at the processing station is fixed by the fixing mechanism, so as to realize the fixed processing and conveying of brake pads in each processing equipment. This makes the post-processing equipment for brake pads highly integrated. After integration, the total length of the entire brake pad production unit can be controlled within 7 meters, which greatly reduces the problem of large floor space required for brake pad production. At the same time, it can also realize continuous production of brake pads and improve the production efficiency of brake pads. Attached Figure Description

[0027] like Figures 1-6As shown, this embodiment of a highly integrated flexible post-processing unit for drum brake pads includes a frame 1 for connecting and fixing a processing mechanism 2 and a conveying unit 3; the processing mechanism 2 is used to process brake pads 11, and the processing mechanism 2 is arranged along the conveying direction of the conveying unit 3. The processing mechanism 2 is equipped with a fixing device 201, which is located along the conveying line of the conveying unit 3. The processing mechanism 2 includes an outer arc rough grinding mechanism 21, a side grinding mechanism 22, an inner arc grinding mechanism 23, a drilling mechanism 24, a drilling mechanism 25, an end grinding mechanism 26, and a chamfering mechanism. 27; Conveying unit 3, used for conveying brake pads 11, and the conveying unit 3 is provided with at least two processing stations 31, the processing stations 31 are used for receiving brake pads 11, and the processing stations 31 are correspondingly arranged with the processing mechanism 2; Along the conveying direction, the conveying unit 3 is at least two sets, the conveying unit 3 includes a pair of conveying rails 32, the bottom of the conveying rails 32 is slidably connected to the frame 1 through a slide rail; First driving device 4, used for driving the conveying rails 32 to slide along the slide rail; Fixing mechanism 5, used for fixing the brake pads 11 on the processing station 31.
[0028] The post-processing unit of this utility model includes several processing mechanisms 2 and conveying units 3 for processing drum brake pads 11. The processing mechanisms 2 are arranged along the conveying direction of the conveying units 3. In processing mechanisms 2 equipped with fixing devices 201, such as the outer arc rough grinding mechanism 21, drilling mechanism 24, and integrated outer arc fine grinding mechanism for the grinding end face, the fixing device 201 is a rotating hub, which is located along the conveying line of the conveying unit 3. In processing mechanisms 2 without fixing devices 201, a processing station 31 is set on the conveying track 32 of the conveying unit 3. After the brake pads 11 are conveyed to the processing station 31 via the conveying track 32, the fixing mechanism 5 fixes the brake pads 11. Under the conveying action of the conveying unit 3, the processing mechanism 2 processes the brake pads 11 on the processing station 31. Several conveying units 3 can be arranged along the conveying line. Specifically, the fixing mechanism 5 can be a clamping block and a clamping cylinder located above the conveying track 32. The clamping cylinder drives the clamping block to move downward, and the brake pad 11 is fixed under the action of the conveying track 32 and the clamping block. The fixing mechanism 5 can also include a clamping plate 51 and a clamping cylinder 52 that drives the clamping plate 51 to rotate. The bottom of the clamping plate 51 is rotatably connected to the conveying track 32, and the clamping cylinder 52 is connected to the conveying track 32. The output end of the clamping cylinder 52 is connected to the clamping plate. The clamping cylinder 52 drives the clamping plate 51 to rotate, which abuts against the end of the brake pad 11 on the conveying track 32, so that the brake pad 11 is processed at the processing station 31 and during the conveying process of the conveying unit 3. A clamping block is provided on the side of the conveying track 32. The clamping block is correspondingly provided with the inner arc grinding mechanism 23. During the inner arc surface processing, the clamping block restricts the axial movement of the brake pad 11, so as to prevent the brake pad 11 from rotating with the inner arc surface processing equipment during the inner arc surface processing.
[0029] The fixing device 201 of the outer arc rough grinding mechanism 21 and the drilling mechanism 24 is a rotating hub. The drilling mechanism 25 and the grinding end mechanism 26 are an integrated processing structure. The fixing device 201 of the drilling mechanism 25 is a horizontal rotating hub. Specifically, the drilling mechanism 25 is equipped with a horizontal hub and a second drive device for driving the horizontal hub to rotate. An end grinding wheel is provided on the left side of the horizontal hub, and a surface grinding wheel for fine grinding the outer arc is provided on the right side. A mechanical gripper is provided above the horizontal hub. The mechanical gripper is used to grab the brake pad 11 at the loading end of the horizontal hub and place the brake pad 11 on the horizontal hub, as well as grab the brake pad 11 that has been processed on the horizontal hub and place the brake pad 11 on the conveying unit 3 at the output end of the horizontal hub. The second drive device drives the hub to rotate. When the hub rotates to the position of the end grinding wheel, the two end grinding wheels on the left side of the horizontal hub process the end face of the brake pad 11. When the hub rotates to the position of the surface grinding wheel, the outer arc surface of the brake pad 11 is finely ground.
[0030] like Figure 5 As shown, when the outer arc rough grinding mechanism 21 or the drilling mechanism 24 is located in the middle of the post-processing unit, the input end of the outer arc rough grinding mechanism 21 or the drilling mechanism 24 is provided with a first flip-type feeding mechanism 6. That is, when the outer arc rough grinding mechanism 21 or the drilling mechanism 24 is located in the middle process of the post-processing unit, the input end of the outer arc rough grinding mechanism 21 or the drilling mechanism 24 is provided with a first flip-type feeding mechanism 6. Specifically, the first flip-type feeding mechanism 6 includes a rotating shaft 61, a feeding unit 62 and a feeding cylinder 63. The feeding unit is a feeding plate with the same curvature as the outer arc surface of the brake pad 11, or a pair of feeding rods. The rotating shaft is rotatably connected to the frame 1 of the post-processing unit. The feeding cylinder pushes the feeding unit to rotate, thereby conveying the brake pad 11 on the feeding unit to the rotating hub of the outer arc rough grinding mechanism 21 or the drilling mechanism 24.
[0031] like Figure 4 As shown, the input end of the conveying track 32 is provided with a first hook 33. One end of the first hook 33 near the input of the conveying track 32 is rotatably connected to the conveying track 32, and the other end is provided with a compression spring between it and the conveying track 32. The upper surface of the first hook 33 is inclined. When the first driving device 4 drives the conveying track 32 to move towards the input end, the input end of the conveying track 32 passes through the bottom of the brake pad 11 below the receiving groove 7. Under the gravity of the brake pad 11, the compression spring is compressed. After the first hook 33 passes through the bottom of the brake pad 11, under the action of the compression spring, the first hook 33 is lifted up and hooks the brake pad 11 at the bottom of the receiving groove 7. Under the action of the first driving device 4, the hooked brake pad 11 moves with the conveying track 32 towards the output end, realizing the conveying of the brake pad 11, which is convenient for the next processing mechanism 2 to process the brake pad 11.
[0032] The output end of the brake pad 11 of the outer arc rough grinding mechanism 21 and the drilling mechanism 24 is provided with a receiving groove 7. The bottom of the receiving groove 7 is provided with a notch for the first hook 33 to move, so that the first hook 33 can hook the brake pad 11 to move after moving.
[0033] The output end of the drilling mechanism 24 is provided with a second flipping mechanism 8 for flipping the brake pad 11 by 180°. Figure 6As shown, specifically, the second flipping mechanism 8 includes a support 81, which is fixedly connected to the frame 1. A flipping shaft 82 and a flipping motor 83 that drives the flipping shaft 82 are rotatably connected above the support 81. A pair of symmetrically arranged flipping arms 84 are provided on the flipping shaft 82. The cross-section of the flipping arms 84 is a "<" shaped structure. After the conveying unit 3 conveys the brake pad 11 into the flipping arms 84, the flipping motor 83 drives the flipping shaft 82 to rotate, realizing a 180° flip of the brake pad 11, which is then conveyed to the next process for subsequent processing. The second flipping mechanism 8 can also be a robotic arm or suction cup capable of flipping 180°.
[0034] A mechanical gripper is provided above the fixing device 201 of the drilling mechanism 25. The mechanical gripper is used to grasp the brake pad 11 on the input end of the drilling mechanism 25 and place the brake pad 11 onto the horizontal rotating hub. After the brake pad 11 is processed on the horizontal rotating hub, the mechanical gripper grasps the brake pad 11 on the horizontal rotating hub and places the brake pad 11 onto the conveying unit 3 at the output end of the drilling mechanism 25. Preferably, there are two mechanical grippers, which are movably connected to the frame 1. One mechanical gripper performs the loading operation of the fixing device 201 of the drilling mechanism 25, and the other performs the unloading operation.
[0035] A one-way movable baffle 9 is provided above the conveying track 32. The lower end of the one-way movable baffle 9 is lower than the upper surface of the brake pad 11 above the conveying track 32. The connecting end of the one-way movable baffle 9 can be located on the side of the conveying track 32 or above the conveying track 32. When the connecting end of the one-way movable baffle 9 is located above the conveying track 32, the upper end of the one-way movable baffle 9 is rotatably connected to the frame 1, and the side of the one-way movable baffle 9 near the input end of the conveying unit 3 is in contact with the frame 1. When the conveying unit 3 moves toward the output end, the one-way movable baffle 9 is pushed up by the brake pad 11 until one brake pad 11 has completely passed the one-way movable baffle 9; the one-way movable baffle 9 hangs down under the action of gravity, and under the action of the side frame 1, when the conveying unit 3 moves toward the input end, the one-way movable baffle 9 prevents the brake pad 11 above the conveying track 32 from moving back with the conveying unit 3, so as to realize the one-way movement of the brake pad 11 on the conveying unit 3 and realize the conveying of the brake pad 11.
[0036] The processing station 31 is provided with a limiting block 10 near the input end of the conveying unit 3. The upper surface of the limiting block 10 is not higher than the upper surface of the conveying track 32 near the input end of the conveying unit 3. During the process of conveying the brake pad 11, the conveying unit 3 facilitates the processing mechanism 2 to process the brake pad 11 under the action of the limiting block 10, such as side processing, chamfering, etc.
[0037] Along the conveying direction of the conveying unit 3, the processing mechanism 2 consists of an outer arc rough grinding mechanism 21, a side grinding mechanism 22, an inner arc grinding mechanism 23, a drilling mechanism 24, a fine grinding mechanism for the outer arc and both ends 26, and a chamfering mechanism 27.
[0038] Each set of conveying units 3 has a receiving platform at its output end. The upper surface of the receiving platform is lower than the output end of the conveying track 32, and a pair of receiving platforms are located outside the conveying track 32. The conveying unit 3 conveys the brake pads 11 to the receiving platform. The first flipping feeding mechanism sends the brake pads 11 to the next hub-type processing mechanism 2 by flipping, or the brake pads 11 are conveyed out by the unloading mechanism.
[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
