Description

Technical Field

[0001] This utility model relates to the field of brake pad processing technology, specifically a surface treatment device for the steel back of passenger vehicle brake pads. Background Technology

[0002] The surface treatment of the steel backing of brake pads is crucial to improving brake pad performance and durability. It requires processes such as grooving, grinding, chamfering, and drilling to ensure the fit between the steel backing and the friction material and the braking performance.

[0003] Currently, brake pads need to be polished after machining or before processing to ensure the accuracy of the process and the effect of later use. Due to the small size of brake pads, polishing is inconvenient. Current polishing fixtures do not have the effect of clamping them one by one and can only be polished individually, which greatly reduces the processing efficiency. At the same time, the debris and shavings generated during polishing seriously affect the working environment. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: including a shell 1, with a partition 2 connected between the inner walls of the shell 1, a feeding cylinder 3 connected to the bottom end of the partition 2, the output end of the feeding cylinder 3 passing through the partition 2 and connected to a push plate 4, a loading platform 5 rotatably mounted on the top of the push plate 4, a placement rack 6 connected to the top of the loading platform 5, a pressing cylinder 7 connected to the top of the shell 1, the output end of the pressing cylinder 7 passing through the shell 1 and connected to a connecting ring 8, a recycling mechanism rotatably mounted on the bottom end of the connecting ring 8, a grinding disc 11 connected to the bottom end of the recycling mechanism, a connecting frame 12 connected to the top of the grinding disc 11, and multiple sets of magnet blocks 13 connected to the inner ring of the connecting frame 12;

[0021] Reference Figure 2 As shown, the recovery mechanism includes an air chamber 9 rotatably mounted at the bottom of the connecting ring 8. A gas collection hood 14 is connected to the top of the air chamber 9, and a dust extraction pipe 15 is rotatably mounted on the top of the gas collection hood 14. An air pump 16 is connected to the other end of the dust extraction pipe 15. Multiple sets of connecting pipes 10 are connected to the outer ring of the air chamber 9. The other end of the connecting pipe 10 is connected to the grinding disc 11. During grinding, the air pump 16 draws air from the air chamber 9 through the dust extraction pipe 15, creating a negative pressure inside the air chamber 9. External air is then drawn out through the connecting pipes 10. Since the other end of the connecting pipe 10 is close to the grinding disc 11, the debris and dust generated during grinding will immediately enter the air chamber 9 and be drawn out by the air pump 16. A filter is connected to the other end of the air pump 16 to filter out the debris generated during grinding. As this is a standard setting, it is not described in detail in the instruction manual.

[0022] Referring to Figure 1, a guide frame 19 is connected to the top of the housing 1. The impurity extraction pipe 15 passes through the guide frame 19 and is connected to the air pump 16. The guide frame 19 serves to guide and support the impurity extraction pipe 15. When the pressing cylinder 7 drives the air chamber 9 to press down or move up through the connecting ring 8, the impurity extraction pipe 15 will move accordingly. The guide frame 19 then serves to protect the impurity extraction pipe 15.

[0023] Reference Figure 2 and Figure 4As shown, a protective frame 17 is connected to the outer surface of the housing 1, and a winding coil 18 is connected inside the protective frame 17. The winding coil 18 is connected to an external power supply and a controller. Since this is a conventional setup, it will not be described in detail in the instruction manual. When the winding coil 18 is energized, a magnetic field is generated, which drives the connecting frame 12 to rotate through the interaction between the magnet blocks 13. This, in turn, drives the grinding disc 11 to rotate and begin grinding. The winding coil 18 and the protective frame 17 are equivalent to the stator, and the connecting frame 12 and the magnet blocks 13 are equivalent to the rotor. The principle is quite common, so it will not be described in detail.

[0024] Reference Figure 2 As shown, a support pad 41 is connected to the top of the push plate 4, and two guide rods 42 are connected to the bottom. The guide rods 42 are slidably connected to the partition plate 2. When the loading platform 5 rotates to be directly above the push plate 4, the support pad 41 provides support for the loading platform 5. When the push plate 4 drives the loading platform 5 to move up and down, the guide rods 42 provide guidance and stability.

[0025] Reference Figure 2 and Figure 3 As shown, connecting plates 111 are connected to both the inner and outer sides of the bottom of the grinding disc 11. The connecting plates 111 are fitted into the placement frame 6. The connecting frame 12 is fixedly installed on the top of the connecting plate 111 on the outer ring. The setting of the connecting plate 111 can effectively increase the fit between the grinding disc 11 and the brake pad, and can also effectively prevent the debris from splashing inside the housing 1 during grinding, and also ensure the stable connection with the connecting frame 12.

[0026] Reference Figure 2 As shown, a round shaft is connected to one side of the top of the push plate 4, and the other end of the round shaft is rotatably connected to the loading platform 5. A rotating outlet is opened on one side of the housing 1 corresponding to the loading platform 5, which makes loading and unloading convenient. The loading platform 5 can be rotated out directly by rotating, and the brake pads can be fastened in the placement rack 6. Multiple brake pads can be polished at the same time.

[0027] The implementation principle of this application is as follows: When using this utility model, the brake pads are placed in the slots on the placement rack 6, and then the loading platform 5 is directly rotated into the housing 1. The feeding cylinder 3 extends and pushes the loading platform 5 upward through the push plate 4 until the loading platform 5 moves out of the range of the rotation outlet. Then the pressing cylinder 7 presses down, driving the recycling mechanism to move downward, while the grinding disc 11 is attached to the surface of each brake pad. The winding coil 18 is energized, and the magnetic force pushes the magnet block 13, thereby driving the grinding disc 11 to rotate through the connecting frame 12 to grind the brake pads. During the grinding process, the recycling mechanism will suck out the debris and dust generated during grinding and process them.
