[0032] Example 1

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 , which is the first embodiment of the utility model, provides a brake hub circular runout detection device, including a workbench 1 and a turntable 101. The turntable 101 is arranged on the upper surface of the workbench 1, and a positioning assembly 2 is arranged inside the turntable 101.

[0034] Specifically, the positioning assembly 2 includes a protective sleeve 201 fixedly mounted on the upper surface of the turntable 101, the inner cavity of the protective sleeve 201 is rotatably connected to a rotating plate 204, a plurality of arc-shaped slide rails 205 are provided inside the rotating plate 204, the inner wall of the arc-shaped slide rail 205 is slidably connected to a short rod 206, one end of the short rod 206 is fixedly connected to a slider 207, the upper surface of the slider 207 is fixedly connected to an arc-shaped clamping plate 208, the inner cavity of the protective sleeve 201 is fixedly connected to a side plate, the side of the side plate is fixedly connected to a motor 202, the output shaft end of the motor 202 is fixedly connected to a worm 203, the outer surface of the arc-shaped clamping plate 208 is fixedly connected to a silicone pad 209, a slide rail 211 is provided inside the protective sleeve 201, the outer surface of the slider 207 is slidably connected to the inner wall of the slide rail 211, the outer surface of the rotating plate 204 is fixedly connected to a worm wheel 210, and the worm wheel 210 and the worm 203 are meshed.

[0035] Furthermore, the starting motor 202 drives the worm 203 to rotate. Since the worm 203 and the worm wheel 210 are meshed, when the worm 203 rotates, it will drive the worm wheel 210 to rotate, and then drive the rotating plate 204 to rotate. When the rotating plate 204 rotates, the arc slide rail 205 fixed thereon will also rotate accordingly, further driving the short rod 206 to move along the path of the arc slide rail 205. Further, when the short rod 206 moves, it will drive the arc clamping plate 208 to move through the slider 207, so that the silicone pad 209 of the arc clamping plate 208 is close to the surface of the brake hub, forming a stable clamping force to ensure that the position of the brake hub is fixed during the detection process.

[0036] Example 2

[0037] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and a replacement component 3 is provided on the upper surface of the workbench 1.

[0038] Specifically, the replacement component 3 includes a support plate 301 fixedly installed on the upper surface of the workbench 1, a slide groove 302 is provided inside the support plate 301, a sliding block 303 is slidably connected to the inner wall of the slide groove 302, a connecting plate 304 is fixedly connected to the side of the sliding block 303, a threaded hole 305 is provided inside the connecting plate 304, a threaded rod 306 is threadedly connected to the inner wall of the threaded hole 305, one end of the threaded rod 306 is fixedly connected to a detector 307, a probe 308 is fixedly connected to the outer surface of the detector 307, a limiting groove 309 is provided on the inner wall of the threaded hole 305, a protrusion 310 is clamped in the inner cavity of the limiting groove 309, a moving rod 312 is fixedly connected to the side of the protrusion 310, a spring 311 is sleeved on the outer surface of the moving rod 312, the moving rod 312 is inserted into the outer surface of the connecting plate 304 and is fixedly connected to a pull plate, and an electric push rod 313 is fixedly connected between the inside of the slide groove 302 and the sliding block 303.

[0039] Furthermore, when the movable rod 312 moves, the protrusion 310 will be driven to disengage from the limit groove 309. When the protrusion 310 moves, the spring 311 will be compressed, thereby releasing the locking state of the threaded rod 306 and the threaded hole 305. At this time, the threaded rod 306 is rotated to separate it from the threaded hole 305, so that the detector 307 and the probe 308 can be disassembled for replacement or repair. Conversely, they can be installed, thereby ensuring the convenience of replacement and maintenance of the probe 308, greatly improving the flexibility and maintenance efficiency of the equipment.

[0040] Working principle: When in use, first place the brake hub above the protective sleeve 201 and between the arc-shaped clamping plates 208, then start the motor 202 to drive the worm 203 to rotate. Since the worm 203 and the worm wheel 210 are meshed, when the worm 203 rotates, it will drive the worm wheel 210 to rotate, and then drive the rotating plate 204 to rotate. When the rotating plate 204 rotates, the arc-shaped slide rail 205 fixed thereon will also rotate, further driving the short rod 206 to move along the path of the arc-shaped slide rail 205. When the short rod 206 During movement, the arc-shaped clamping plate 208 will be driven to move by the slider 207, so that the silicone pad 209 of the arc-shaped clamping plate 208 is close to the surface of the brake hub, forming a stable clamping force, ensuring that the position of the brake hub is fixed during the detection process. At the same time, when the slider 207 moves, it will slide in the slide rail 211 to support and limit the arc-shaped clamping plate 208, avoiding the brake hub from being offset or vibrating due to the rotating force when the turntable 101 rotates, affecting the accuracy of the detection result, and ensuring the stability of the brake hub during the detection process.

[0041] Subsequently, the electric push rod 313 drives the sliding block 303 to slide in the slide groove 302, so as to drive the connecting plate 304 to move up and down. When the connecting plate 304 moves, it drives the probe 308 of the detector 307 to move, so that the probe 308 contacts the brake hub. After the position of the detector 307 is adjusted, the turntable 101 is started to drive the fixed brake hub to rotate. During the rotation of the brake hub, the probe 308 monitors the radial runout of the brake hub surface in real time. The data will be recorded and analyzed by the detector 307 to evaluate the circular runout performance of the brake hub. When the probe 307 needs to be adjusted, the rotation plate 101 is turned on and the rotation plate 101 is turned on. 08When replacing or repairing, the staff pulls the moving rod 312 backward. When the moving rod 312 moves, it will drive the protrusion 310 to disengage from the limiting groove 309. When the protrusion 310 moves, it will drive the spring 311 to be compressed, thereby releasing the locking state of the threaded rod 306 and the threaded hole 305. At this time, the threaded rod 306 is rotated to separate it from the threaded hole 305, so that the detector 307 and the probe 308 can be disassembled for replacement or repair, and vice versa, they can be installed, thereby ensuring the convenience of replacement and maintenance of the probe 308, greatly improving the flexibility and maintenance efficiency of the equipment.

[0042] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
