Technical Field

[0001] This utility model relates to the field of brake pad processing technology, and in particular to a brake pad electromagnetic chuck clamp. Background Technology

[0002] Brake pads are the core component of a braking system that achieves deceleration or stopping through friction. They are commonly found in vehicles, rail transportation, and industrial equipment, and are usually made of metal composite materials. When machining metal-based brake pads, electromagnetic chucks are often used in milling machines, grinding machines, and other equipment to quickly attract and fix magnetically conductive metal workpieces using electromagnetic force, ensuring machining accuracy and stability.

[0003] Electromagnetic positioning fixtures typically include a magnetic chuck, a magnetic conductor, an insulating layer, a power module, a control unit, a cooling system, a fixed base, and an adjustment mechanism. They achieve rapid positioning and stable clamping of workpieces through magnetic attraction and mechanical assistance. To reduce frictional damage between the magnetic surface and the casting, designers typically install several pads on the magnetic chuck that do not interfere with magnetic attraction. These pads are usually fixed to the magnetic chuck using bolt connections or plug-in methods for easy replacement. However, since replacing these pads requires tools, the tools may not be readily available during processing, affecting the subsequent use of the electromagnetic chuck fixture. Utility Model Content

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] according to Figure 1 , 2 As shown in Figures 3, 4, and 5, this embodiment proposes a brake pad electromagnetic chuck clamp, which includes an electromagnetic chuck 2, a magnetic suction part, a tooling table 1, and a power controller 3. The tooling table 1 is fixedly installed at the lower end of the electromagnetic chuck 2, the magnetic suction part is fixedly installed at the upper end of the electromagnetic chuck 2, and the power controller 3 is fixedly installed on the outside of the electromagnetic chuck 2.

[0026] The magnetic attraction part includes several magnetic blocks 4, and a magnetic pad 5 is sleeved on the upper end of the magnetic block 4. A locking mechanism is provided on the opposite side of the magnetic block 4 and the magnetic pad 5.

[0027] Each magnetic block 4 is arranged in a rectangular array. The electromagnetic chuck 2 is activated by the placement bracket 7. The electromagnetic chuck 2 and the magnetic blocks 4 generate magnetic attraction to fix the brake plate placed on the upper end of the electromagnetic chuck 2. The magnetic pads 5 sleeved on the magnetic blocks 4 play a protective role for the electromagnetic chuck 2 and the brake plate, which can reduce frictional damage between the electromagnetic chuck 2 and the brake plate. The snap-fit ​​assembly of the magnetic pads 5 makes it easy for the staff to replace them.

[0028] One side of the electromagnetic chuck 2 has a tool 8 for easily removing the magnetic pad 5. The outer side of the electromagnetic chuck 2 has a support 7 for storing the tool 8. The support 7 is detachably connected to the electromagnetic chuck 2 and has a magnetic structure to prevent the tool 8 from falling off. When not in use, the tool 8 is stored in the support 7 on the outside of the electromagnetic chuck 2. The support 7 locks the tool 8 in place using the magnetic structure, ensuring it is not lost. This facilitates timely replacement of the magnetic pad 5 by staff, making it convenient and practical.

[0029] Regarding the snap-fit ​​structure:

[0030] The locking mechanism includes a slot 51 at the lower end of the magnetic pad 5, which is slidably connected to the magnetic block 4. A pin 52 is located in the center of the slot 51, which is fixedly connected to the magnetic pad 5 and slidably connected to a limiting hole 6 at the upper end of the magnetic block 4. When the magnetic pad 5 is fitted onto the end of the magnetic block 4, the pin 52 on the inner side of the magnetic pad 5 will simultaneously insert into the limiting hole 6 at the top of the magnetic block 4. The limiting hole 6, in cooperation with the pin 52, limits the magnetic pad 5.

[0031] Regarding plug-in / plug-out tools 8:

[0032] The insertion and removal tool 8 includes a handle 81, with two rectangular frames 82 at the lower end of the handle 81, which are fixedly connected to the handle 81. A triangular frame 83 is also fixedly connected to the lower end of the rectangular frames 82. The tool is used to open the two triangular frames 83 with fingers, insert the magnetic pad 5 between the two triangular frames 83, and slide the bottom of the triangular frames 83 to the left and right sides of the magnetic block 4. Pulling the handle 81 upwards allows the handle 81 to directly pull the magnetic pad 5 upwards through the triangular frames 83, saving manpower.

[0033] It is worth explaining in detail that the placement bracket 7 includes a first anchor 71, and a fixed post 73 is provided on one side of the first anchor 71. The fixed post 73 is fixedly connected to the first anchor 71 and passes through the two rectangular frames 82. A movable post 74 is provided at the end of the fixed post 73 away from the first anchor 71, and the movable post 74 is hinged to the fixed post 73. When the insertion and removal tool 8 is stored, the rectangular frame 82 at the lower end of the handle 81 is placed on the outside of the fixed post 73. The fixed post 73 will support the insertion and removal tool 8. Moving the movable post 74 will cause the movable post 74 to flip. The movable post 74, in conjunction with the magnetic structure, will prevent the rectangular frame 82 from falling off the fixed post 73.

[0034] More specifically, the magnetic attraction structure includes a second anchor 75, which is located between the electromagnetic chuck 2 and the fixed post 73. The second anchor 75 is detachably connected to the outside of the electromagnetic chuck 2. Magnets 77 are provided on the opposite sides of the second anchor 75 and the movable post 74. The magnets 77 are fixedly installed at the end of the movable post 74 away from the fixed post 73. When the fixed post 73 is rotated, and a vertical angle is formed between the movable post 74 and the fixed post 73, the magnet 77 at the end of the movable post 74 will attract the magnet 77 at the end of the second anchor 75, thus limiting the position of the rectangular frame 82.

[0035] To facilitate the replacement of the bracket 7, multiple first fixing bolts 72 are fitted to the outer side of the first fixing seat 71, and multiple second fixing bolts 76 are fitted to the outer side of the second fixing seat 75. The first fixing bolts 72 and the second fixing bolts 76 are threadedly connected to the bolt holes on the outer side of the electromagnetic chuck 2. When replacing the bracket 7 and the magnetic suction structure, simply unscrew the first fixing bolts 72 on the first fixing seat 71 and the second fixing bolts 76 on the second fixing seat 75 from their corresponding bolt holes.

[0036] In a preferred embodiment, both ends of the handle 81 are provided with protrusions 84, which are integrally formed with the handle 81. The lower end face of the handle 81 is provided with multiple slots 85. The slots 85 are provided for the user to grip, and the protrusions 84 are fixedly set at both ends of the handle 81 to prevent it from falling off.

[0037] To further secure the brake pad, in a preferred embodiment, the electromagnetic chuck 2 has several positioning holes on its upper end, positioned between two adjacent magnetic blocks 4. Limit pins 9 are fitted onto these positioning holes, and the limit pins 9 are threadedly connected to the positioning holes via bolts. After the brake pad is placed on the upper end of the electromagnetic chuck 2, the electromagnetic chuck 2 secures the brake pad magnetically. Then, the limit pins 9 are screwed into the corresponding positioning holes, and the lower end face of the limit pins 9 presses down on the brake pad, preventing it from loosening during processing.

[0038] How this application works:

[0039] The magnetic blocks 4 are arranged in a rectangular array. The electromagnetic chuck 2 is activated by the support bracket 7. The electromagnetic chuck 2 and the magnetic blocks 4 generate magnetic attraction, fixing the brake pad placed on top of the electromagnetic chuck 2. The magnetic pads 5 fitted on the magnetic blocks 4 protect the electromagnetic chuck 2 and the brake pad, reducing frictional damage between them. The snap-fit ​​assembly of the magnetic pads 5 facilitates replacement by the operator. When not in use, the insertion / removal tool 8 is stored on the support bracket 7 outside the electromagnetic chuck 2. The support bracket 7 locks the insertion / removal tool 8 with a magnetic structure, ensuring it is not lost and facilitating timely replacement of the magnetic pads 5 by the operator. This design is convenient and practical.
