[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] Reference Figure 1-5, which is the first embodiment of the utility model, provides a wear resistance detection device for brake shoe production, which includes a base 1 installed on a connecting column 11 on the top of the base 1, a workbench 12 fixed on the top of the connecting column 11, a brake shoe 13 located on the surface of the workbench 12, and a detection member 2 installed inside the base 1. The base 1 and the workbench 12 are fixedly connected by the connecting column 11, forming a cavity therebetween. The detection member 2 includes a motor, a rotating shaft and a friction plate. It is a very mature existing technology and will not be elaborated on here. A clamping member 3 is installed on the surface of the workbench 12, and a heat sink 4 is provided inside the workbench 12;

[0027] The clamping member 3 includes an arc-shaped plate 31 fixed to the surface of the workbench 12, the brake shoe 13 is located on the inner side of the arc-shaped plate 31, and a lifting clamping structure 32 is installed on the top of the arc-shaped plate 31. Positioning members 33 are installed on both sides of the arc-shaped plate 31. The positioning members 33 are located at both ends of the brake shoe 13. The lifting clamping structure 32 includes a telescopic rod and a clamping plate, and the bottom of the clamping plate is installed with equidistantly arranged clamping balls, which can preliminarily fix the brake shoe 13. This structure is a prior art and will not be elaborated here.

[0028] The positioning member 33 includes a supporting plate 331 movably connected to the two ends of the arc-shaped plate 31. The internal thread of the supporting plate 331 is connected to a bolt 332. One end of the bolt 332 is rotatably connected to a top plate 333. The top plate 333 is located on the inner side of the supporting plate 331. One end of the bolt 332 passes through the supporting plate 331, and one end thereof extends to the inner side of the supporting plate 331 and is rotatably connected to the top plate 333, so as to drive the top plate 333 to move toward the two ends of the brake shoe 13.

[0029] One end of the top plate 333 and the end away from the bolt 332 is fixedly connected to a positioning plate 334, and rubber balls 335 are installed on the surface of the positioning plate 334. The rubber balls 335 are arranged at equal intervals. The arrangement of the positioning plate 334 facilitates contact with the brake shoe 13. At the same time, the rubber balls 335 can increase the friction with the brake shoe 13 to better position it and prevent it from moving horizontally.

[0030] A guide groove 336 is formed on the inner side of the supporting plate 331 , and guide blocks 337 are fixedly connected to both sides of the top plate 333 . The guide blocks 337 are located inside the guide groove 336 and are movably connected thereto to maintain the stability of the top plate 333 when moving.

[0031] Both ends of the arc-shaped plate 31 are provided with a sliding groove 311 and a positioning groove 312. The sliding groove 311 and the positioning groove 312 are arranged perpendicularly, and the positioning grooves 312 are arranged equidistantly. A group of positioning grooves 312 are movably connected to the inside of a positioning block 313. The positioning block 313 is located on the top of the supporting plate 331 and can position the supporting plate 331 so that its internal structure can firmly position the brake shoe 13.

[0032] The surface of the base 1 is fixedly connected to a spring 314, and a damper is provided inside the spring 314. The top of the spring 314 passes through the workbench 12 and is located at the bottom of the supporting plate 331 and is fixedly connected thereto. The spring 314 is movably connected to the workbench 12. The setting of the spring 314 can make the supporting plate 331 have elastic force, which can facilitate the placement of the brake shoe 13 inside the arc plate 31, avoiding the inconvenience of clamping and canceling the clamping operation of the brake shoe 13 due to the setting of the supporting plate 331 and other structures. It can be used in conjunction with the positioning plate 334 to facilitate the removal of the brake shoe 13.

[0033] A connecting block 316 is fixedly connected to one side of the supporting plate 331, and a slider 315 is fixedly connected to the inside of the connecting block 316. The connecting block 316 is sleeved on both ends of the arc plate 31 and is movably connected thereto. The slider 315 is located inside the slide groove 311 and is movably connected thereto. Through the setting of the connecting block 316, the positioning member 33 can be sleeved on both ends of the arc plate 31 to facilitate the removal of the brake shoe 13, and at the same time, it can facilitate the positioning of the two ends of the brake shoe 13, thereby avoiding its translation due to the rotation of the friction plate.

[0034] The heat sink 4 includes heat sink fins 41 located inside the workbench 12. The heat sink fins 41 are arranged at equal intervals. A group of heat sink fins 41 is located on one side of the brake shoe 13. A heat conducting rod 42 is fixedly connected to the interior of the heat sink fins 41. The heat sink fins 41 can increase the contact area between the heat sink fins 41 and the brake shoe 13, thereby enhancing heat transfer and heat dissipation. At the same time, the heat sink fins 41 have good heat dissipation properties and can quickly transfer and discharge heat between the heat sink fins 41 and the brake shoe 13, further improving heat dissipation efficiency.

[0035] A cooling fan 43 is provided on the surface of another set of cooling fins 41. Connecting rods 44 are installed on the top and bottom of the cooling fan 43. A cooling shell 45 is installed on one side of the workbench 12. The cooling fan 43 is located inside the cooling shell 45 and is fixedly connected by the connecting rod 44. The surface of the cooling fan 43 is provided with equidistantly arranged heat sinks.

[0036] During use, the brake shoe 13 is placed on the surface of the workbench 12, that is, on the inner side of the curved plate 31. Then, the bolt 332 is rotated to push the top plate 333, driving the positioning plate 334 and the rubber ball 335 to move toward the two ends of the brake shoe 13 until the rubber ball 335 firmly fixes the two ends.

[0037] Subsequently, the lifting and clamping structure 32 is activated to apply pressure to the top of the brake shoe 13, that is, the arc plate 31 performs preliminary positioning on the brake shoe 13, and the lifting and clamping structure 32 fixes the top of the brake shoe 13 to prevent the risk of it shaking up and down during testing. The positioning parts 33 are used to position the two ends of the brake shoe 13 to prevent it from shifting during the testing process, thereby achieving a stable positioning of the brake shoe 13, thereby improving work efficiency.

[0038] When the brake shoe 13 is tested, it will generate high temperature. At the same time, one side of the heat dissipation fin 41 is in contact with it, which can increase the contact area between the heat dissipation fin 41 and the brake shoe 13, thereby enhancing the heat transfer and heat dissipation effect. At the same time, the heat dissipation fin 41 has good heat dissipation properties. The heat dissipation fan 43 can quickly transfer and discharge the heat between the heat dissipation fin 41 and the brake shoe 13, further improving the heat dissipation efficiency and avoiding the impact of high temperature on the brake shoe 13.

[0039] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
