Description

Technical Field

[0001] This utility model relates to the field of brake pad manufacturing technology, and in particular to a flexible side processing device for drum brake pads. Background Technology

[0002] In automotive braking systems, drum brake pads are a key component, and their performance directly affects the safety and stability of the vehicle. Due to the diversity of car models, the size and structure of drum brake pads also vary significantly. Different car models, considering factors such as braking performance and space layout, use brake pads with different parameters such as length, width, thickness, and side angle.

[0003] In the processing of drum brake pads, especially in the side processing, existing equipment can only process brake pads of the same model or size. If other sizes of brake pads are to be processed, multiple processing machines of different models are often required. This not only increases production costs and production cycle, but also reduces production efficiency and increases the floor space occupied by the enterprise's production equipment. Utility Model Content

Its design is reasonable and can be used for the production of brake pad sides of different models, thus solving the aforementioned problems in existing technologies.

One end of the anti-deviation rod is rotatably connected to the base, and the other end passes through the oval hole of the frame and is movably connected to the frame. The outer wall of the anti-deviation rod is in contact with the oval hole of the frame.

[0010] Furthermore, it also includes a fixing block, which is fixedly connected to the base. The anti-deviation rod has a T-shaped structure. The fixing block is provided with a groove, and a second oval hole is provided at the bottom of the groove.

[0024] like Figures 1-4 As shown, this embodiment of a flexible side processing device for drum brake pads includes a frame 1, which is equipped with a processing unit 2, a support unit 3, an adjustment unit 4, and a first drive device 5. The processing unit 2 is used to process the side of the brake pad, and includes a grinding wheel 21 and a second drive device 22 for driving the grinding wheel 21 to rotate. The support unit 3 is used to support the brake pad. The adjustment unit 4 is used to adjust the position and angle of the grinding wheel 21, and includes a base 41. A support 42 for fixing the second drive device 22 is provided above the base 41, and the base 41 is rotatably connected to the frame 1 via a rotating shaft 43. The first drive device 5 is used to drive the support unit 3 and the processing unit 2 to slide relative to each other. A locking mechanism 6 is used to fix the base 41 to the frame 1. During processing, the brake pad is located above the support unit 3, and the first drive device 5 causes the support unit 3 and the processing unit 2 to slide relative to each other, thereby allowing the processing unit 2 to grind or chamfer the side of the brake pad. By rotating the rotating shaft 43, the angle between the base 41 and the frame 1 or the horizontal plane can be adjusted, thereby achieving different side processing requirements for the brake pads.

[0025] The support 42 is slidably connected to the base 41 via a first slide rail. The base 41 is provided with a third driving device 44 for driving the support 42 to slide. The direction in which the support 42 slides with the base 41 is perpendicular to the direction in which the support unit 3 and the processing unit 2 slide relative to each other. This facilitates the adjustment of the distance between the grinding wheel 21 and the support unit 3, thereby enabling the processing of the sides of different types of brake pads.

[0026] The support unit 3 includes a pair of conveying rails, which are slidably connected to the frame 1 via a second slide rail. The first drive device 5 is connected to the conveying rails. The brake pads are on the conveying rails, and the first drive device 5 drives the conveying rails to move, thereby enabling the grinding wheel 21 to process the sides of the brake pads.

[0027] The locking mechanism 6 includes a locking plate 61 and a locking nut 62. The locking plate 61 is provided with a through hole. One end of the locking plate 61 is connected to the base 41 or the frame 1, and the other end is connected to the frame 1 or the base 41 through the locking nut 62. After rotating the base 41 and adjusting the angle of the processing unit 2, the base 41 is fixed by the locking nut 62.

[0028] The base 41 is equipped with an anti-deviation mechanism 7, which includes an anti-deviation rod 71. One end of the anti-deviation rod 71 is rotatably connected to the base 41, and the other end passes through an oval hole in the frame 1 and is movably connected to the frame 1. The outer wall of the anti-deviation rod 71 contacts the oval hole in the frame 1. The anti-deviation mechanism 7 prevents the axis of the grinding wheel 21 from tilting, thus affecting the processing quality of the brake pad side. Preferably, the anti-deviation mechanism 7 also includes a fixing block 72, which is fixedly connected to the base 41. The anti-deviation rod 71 has a T-shaped structure, and the fixing block 72 has a groove with a second oval hole at the bottom. One end of the anti-deviation rod 71 is located in the groove, and the other end passes through the first and second oval holes in sequence. The first and second oval holes prevent the axis of the grinding wheel 21 from shifting and also limit the rotation angle of the base 41, avoiding excessive rotation of the base 41.

[0029] The frame 1 is equipped with a fixing mechanism for fixing the brake pads on the support unit 3. Specifically, the fixing mechanism includes a pressure plate or pressure rod and a drive cylinder that drives the pressure plate or pressure rod. The drive cylinder drives the pressure plate or pressure rod to press the two ends or the upper surface of the brake pad, fixing the brake pad above the support unit 3, thus facilitating the grinding wheel 21 to process the sides of the brake pad. The fixing mechanism can be located above or below the support unit 3. When the fixing mechanism is located below the support unit 3, the fixing unit is connected to the support unit 3. Alternatively, the support unit 3 is equipped with a limit block, and a pressure plate or pressure rod and a drive cylinder are provided on the other side. The drive cylinder drives the pressure plate or pressure rod to fix the brake pads on the support unit 3.

[0030] The frame 1 is provided with a receiving groove 8, which is located below the grinding wheel 21 and is used to receive the debris from the grinding wheel 21.

[0031] The support unit 3 is symmetrically provided with the processing unit 2 and the adjustment unit 4 on both sides. Through the symmetrically provided processing unit 2 and adjustment unit 4, the processing of both sides of the brake pad can be realized at the same time.

[0032] 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.
