DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 2 The brake disc size detection device includes a device frame 2, a clamping seat 3 is rotatably provided at the bottom side of the device frame 2, and the clamping seat 3 is used to place the brake disc 1. The top of the device frame 2 is located directly above the clamping seat 3 and is slidably penetrated by a pressing piece 4. After the pressing piece 4 is pressed down, the brake disc 1 is fixed on the clamping seat 3. At the same time, a cross rail 5 is fixed on the device frame, and a movable frame 6 is slidably provided on the cross rail 5. A height gauge 7 is installed on the movable frame 6. The movable frame 6 is used to slide on the cross rail 5 to drive the height gauge 7 to move onto the brake disc 1, and the detection probe of the height gauge 7 contacts the top surface of the brake disc 1. A linkage mechanism 8 is installed on the device. The linkage mechanism 8 is used to push the pressing piece 4 downward and the movable frame 6 horizontally. After the linkage mechanism 8 is started, the pressing piece 4 is first moved downward to press the brake disc 1, and then the movable frame 6 is driven to move horizontally, so that the height gauge 7 moves to the top of the brake disc 1.

[0023] See also Figure 1-Figure 3 , brake disc size detection device, linkage mechanism 8 includes a shaft body 81 rotatably arranged on the top of the device frame 2, a motor connected to the shaft body 81 is installed on the device frame, and the shaft body 81 is driven to rotate by starting the motor, and an eccentric disk 82 is fixedly sleeved on the shaft body 81, and the eccentric disk 82 rotates so that the side is in contact with the top of the lower pressure piece 4, and a spring 85 is connected between the top of the lower pressure piece 4 and the device frame 2. When the eccentric disk 82 pushes the lower pressure piece 4 to move downward, the spring 85 is compressed. The setting of the spring 85 ensures that the top of the lower pressure piece 4 is always in contact with the side of the eccentric disk 82, and the rotation of the eccentric disk 82 is used to push the lower pressure piece 4 to move back and forth downward. A belt disk 83 is also fixedly sleeved on the shaft body 81, and the end of the rope body 84 installed on the movable frame 6 is wound on the belt disk 83. A spring 2 86 is connected between the movable frame 6 and the end of the cross rail 5, and the spring 2 86 is used to realize the elastic connection between the movable frame 6 and the end of the cross rail 5;

[0024] The centers of the arc-shaped proximal end of the eccentric disk 82 close to the shaft body 81 and the arc-shaped distal end away from the shaft body 81 are coincident with the shaft body 81. In the initial state, the pressing member 4 is away from the clamping seat 3. At this time, the top of the pressing member 4 is in contact with the arc-shaped proximal end. As the shaft body 81 rotates, the arc-shaped distal end of the eccentric disk 82 gradually approaches the pressing member 4, so that the pressing member 4 is continuously pressed down. When the arc-shaped distal end contacts the pressing member 4, the pressing member 4 completes the clamping and pressing of the brake disc 1. At this time, the rope body 84 is wound to pull the altimeter 7 close to the brake disc 1. During the rotation of the arc-shaped distal end and the contact with the pressing member 4, the rope body 84 is wound to pull the altimeter 7 close to the brake disc 1. , the rope body 84 will be further pulled to pull the altimeter 7 to the top of the brake disc 1. Since the side edge of the bottom detection end of the altimeter 7 is an inclined surface, when the altimeter 7 is close to the brake disc 1, the inclined surface contacts and slides with the brake disc 1 to push the detection end of the altimeter 7 to move up to the top surface of the brake disc 1, or the detection end of the altimeter 7 is manually assisted to be lifted up so that the detection end is to the upper side of the brake disc 1. At this time, the pressing piece 4 will not move downward any further. After the altimeter 7 is moved horizontally into place, the brake disc 1 can be driven to rotate one circle by rotating the clamping seat 3. During this process, the changes in the test data of the altimeter 7 are observed.

[0025] See also Figure 1 and Figure 4 , brake disc size detection device, the clamping seat 3 includes a vertical cylinder 31 rotatably connected to the bottom side of the device frame 2, the vertical cylinder 31 is used for inserting and placing the brake disc 1, and a movable plate 32 is slidably provided in the vertical cylinder 31. A fixed plate 33 is fixed below the movable plate 32 in the vertical cylinder 31, and a spring 37 is connected between the fixed plate 33 and the movable plate 32. Support rods 34 are hingedly connected to the supports of the fixed plate 33 and the movable plate 32. The ends of the two groups of support rods 34 extend out of the vertical holes opened on the upper side wall of the vertical cylinder 31 and extend to the outside, and support plates 35 are hingedly connected to the outer ends of the two groups of support rods 34. There are multiple groups of support plates 34 and 35 distributed around the vertical cylinder 31. As the movable plate 32 moves downward and gradually approaches the fixed plate 33, the arc-shaped plate will be gradually pushed outward. Multiple groups of outward-pushing support plates 34 are supported on the inner ring of the brake disc 1 to fix the brake disc 1. The pressing member 4 is located directly above the movable plate 32. When the pressing member 4 moves downward, it pushes down the movable plate 32. The pressing member 4 can rotate with the movable plate 32. After the brake disc 1 is clamped, the altimeter 7 also moves to the top of the brake disc 1 and the detection end of the bottom side of the altimeter 7 contacts the brake disc 1. At this time, the flatness of the brake disc 1 can be detected by rotating the brake disc 1.

[0026] An extended horizontal plate 36 is fixed to the outer side of the bottom of the support plate 35. The bottom side of the brake disc 1 inserted into the vertical cylinder 31 is placed on the extended horizontal plate 36, and then the brake disc 1 is fixed and clamped by using the outward-moving support plate 35; an inclined guide plate is fixed to the top of the support plate 35, and the top of the inclined guide plate is close to the vertical cylinder 31. The setting of the inclined guide plate ensures that the brake disc 1 is more convenient and smooth when it is placed on the vertical cylinder 31.
