[0002] The bearing profiler is a precision measuring instrument used to measure the profile parameters of wheel bearings. It is usually used to measure the size, shape and geometric characteristics of the inner ring, outer ring and rolling element of the bearing to ensure that the quality of the bearing meets the requirements. The bearing profiler uses high-precision sensors and measurement systems to quickly and accurately measure the bearing profile, including parameters such as diameter, roundness, circumference, end face parallelism, axial runout, etc. The measurement results of the bearing profiler can be used to evaluate the processing quality, assembly accuracy and performance indicators of the bearing, providing an important basis for production process control and quality assurance.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 and Figure 2The utility model provides an embodiment: a bearing profiler measurement and positioning structure, including a workbench 1, the left and right sides of the top wall of the workbench 1 are fixedly connected with support plates 3, the top walls of the two support plates 3 are fixedly connected with a top shell 4, the right side of the top shell 4 is fixedly connected with a servo motor 5, the output end of the servo motor 5 passes through the right side of the top shell 4 and is fixedly connected with a threaded rod 6, the outer wall of the threaded rod 6 is threadedly connected with a displacement plate 7, the bottom wall of the displacement plate 7 is fixedly installed with a measuring device 8, and the front and rear ends of the right side of the inner wall of the top shell 4 are fixedly connected with sliding Column 16, the middle parts of the two sliding columns 16 respectively penetrate the front and rear sides of the inner wall of the displacement plate 7, the middle part of the top wall of the workbench 1 is fixedly connected with a fixing plate 13, the top wall of the fixing plate 13 is fixedly connected with a placement seat 14, the front and rear ends of the left side of the displacement plate 7 are fixedly connected with connecting rods 9, the bottom walls of the two connecting rods 9 are fixedly connected with a cleaning shell 10, the front and rear sides of the inner top wall of the cleaning shell 10 are fixedly connected with springs 11, the bottom ends of the two springs 11 are fixedly connected with cleaning sponge brushes 12, and the front and rear sides of the top wall of the workbench 1 are provided with fixing mechanisms 2;

[0030] Specifically, when the servo motor 5 is started, the threaded rod 6 is driven to rotate. This rotational action gives the displacement plate 7 a tendency to rotate and displace. The rotation of the displacement plate 7 is limited by two sliding posts 16. Therefore, the displacement plate 7 can only be displaced to the left or right along a predetermined path. As the displacement plate 7 moves, the measuring device 8 fixed thereon will also move accordingly, so that the fixed object to be detected can be measured in all directions. This design not only improves the flexibility of measurement, but also ensures the accuracy of measurement. Through the fixation of two connecting rods 9, the cleaning shell 10 and the cleaning sponge brush 12 form an integrated movement mode with the displacement plate 7. When the displacement plate 7 is displaced, the cleaning sponge brush 12 will fit closely to the top wall of the object to be detected and move synchronously. In this process, the cleaning sponge brush 12 can effectively remove dirt and impurities on the surface of the object to be detected, ensuring that the surface of the object to be detected is clean when measuring.

[0031] Reference Figure 1 and Figure 3 The fixing mechanism 2 includes two vertical plates 201, the bottom walls of the two vertical plates 201 are respectively fixedly connected to the front and rear sides of the top wall of the workbench 1, the inner walls of the two vertical plates 201 are fixedly connected with hydraulic rods 202, the output ends of the two hydraulic rods 202 are fixedly connected with mounting plates 203, the two mounting plates 203 are threadedly penetrated with two threaded knobs 204 on the far sides, and the adjacent sides of the plurality of threaded knobs 204 are threadedly connected with clamps 205; the adjacent sides of the two clamps 205 are fixedly installed with rubber pads 206;

[0032] Specifically, by starting the two hydraulic rods 202, their output ends will be displaced toward each other. This displacement will further drive the mounting plate 203 and the clamp 205 fixedly installed by the two threaded knobs 204 to be displaced. This series of actions ensures that the two clamps 205 can tightly clamp the object to be detected placed on the top of the placement seat 14, thereby achieving its fixation and stability. The threaded knob 204 allows us to adjust the specifications of the clamp 205 as needed to adapt to objects to be detected of different shapes and sizes. In addition, the design of the clamp 205 also fully considers its contact area and pressure distribution with the object to be detected to ensure that the object will not be damaged during the clamping process. The two rubber pads 206 make it possible to improve the fixing effect of the two clamps 205.

[0033] Reference Figure 1 , Figure 2 and Figure 3 A control switch 17 is fixedly connected to the front side of the workbench 1, and the control switch 17 is electrically connected to the servo motor 5 and the hydraulic rod 202 respectively; a dust cover 21 is provided on the front side of the control switch 17, and the rear side of the dust cover 21 is rotatably connected to the front side of the workbench 1 through a hinge;

[0034] Specifically, the control switch 17 is electrically connected to the servo motor 5 and the hydraulic rod 202 respectively, so that the control switch 17 can complete the opening and closing of the device, and the dust cover 21 can prevent dust and protect the control switch 17.

[0035] Reference Figure 1 and Figure 2 , a limiting rod 20 is fixedly connected to the left side of the right support plate 3; the left and right sides of the bottom wall of the workbench 1 are fixedly connected to the bottom frame 18, and the front and rear sides of the bottom of the two bottom frames 18 are fixedly installed with corner pads 19; the top wall of the placement seat 14 is provided with a groove 15;

[0036] Specifically, the limiting rod 20 is used to prevent the displacement plate 7 from excessively displacing and causing damage to the servo motor 5, the base frame 18 and the corner pad 19 make the device more stable during operation, and the groove 15 makes it easy to place the object to be detected.

[0037] Working principle: Before starting the measurement, the object to be detected is placed on the top of the placement seat 14, and then the two hydraulic rods 202 are activated to make the output ends of the two hydraulic rods 202 move toward each other, so that the mounting plate 203 and the clamp 205 fixedly installed by two threaded knobs 204 are moved, so that the two clamps 205 can clamp and fix the object to be detected placed on the top of the placement seat 14, so that the device can improve the stability during the detection, thereby avoiding the problem of offset during the bearing measurement, thereby affecting the measurement result, and by driving The servo motor 5 drives the threaded rod 6, so that the threaded rod 6 gives the displacement plate 7 a tendency to rotate and move. When the rotation of the displacement plate 7 is limited by the two sliding columns 16, the displacement plate 7 can be displaced to the left or right, thereby driving the measuring device 8 to measure the fixed object to be detected. Through the displacement of the displacement plate 7, the cleaning shell 10 and the cleaning sponge brush 12 fixed by the two connecting rods 9 are displaced together, so that the top wall of the object to be detected can be cleaned during measurement, thereby avoiding the situation where dirt affects the detection accuracy.
