Description

Technical Field

[0001] The utility model belongs to the technical field of bearing cylindrical roller measurement, and particularly relates to a bearing cylindrical roller size measurement device. Background Technique

[0002] Cylindrical roller bearings are widely used in modern mechanical equipment. Due to their simple structural design, strong load-bearing capacity, stable operation and other characteristics, they are deeply favored by users. As the core component of cylindrical roller bearings, the dimensional accuracy of cylindrical rollers directly determines the overall accuracy, rotational speed and service life of the bearings, thus having an important impact on the performance and reliability of mechanical equipment.

[0003] However, when the existing device measures cylindrical rollers, it cannot accurately measure the arc-shaped outer wall of the cylindrical rollers, which will affect the accuracy and reliability of the measurement results. Because cylindrical rollers have complex geometric shapes, their arc-shaped outer walls cannot obtain accurate dimensional data through simple linear measurement methods. This measurement error will be transmitted to subsequent product design, manufacturing and performance evaluation links, thus affecting the quality and performance of the final product. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bearing cylindrical roller size measurement device. By setting a measurement mechanism, since the arcs at different positions on the roller are different, the displacement distances of multiple pistons will also be different. When the pistons move, they will squeeze the air inside the fixed sleeve, generating pressure in the connecting pipe. The pressure sensor detects and compares the pressure, and can completely present the pressure levels at different positions on the roller, solving the problem that because cylindrical rollers have complex geometric shapes, their arc-shaped outer walls cannot obtain accurate dimensional data through simple linear measurement methods.

[0005] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0006] The utility model is a bearing cylindrical roller size measurement device, including a support frame and rollers. A moving mechanism and a measurement mechanism are arranged on the support frame. The moving mechanism includes a fixing component, a limiting component and a driving component;

The output ends of the two electric cylinders are fixedly connected to a top plate. A measuring ruler is fixedly connected to the top surface of the moving plate. The measuring ruler slidably penetrates through the top plate. A number of rollers are placed on the top surface of the moving plate. The bottom surface of the top plate is in contact with the top surfaces of the number of rollers.

[0008] Further, the limiting component includes limiting sliding grooves respectively formed on the front side and the rear side of the moving plate, and two limiting sliding rails are fixedly connected to the inner wall of the support frame, and the inner walls of the two limiting sliding grooves are respectively slidably connected to the two limiting sliding rails.

[0009] Further, the driving component includes a motor fixedly connected to the right side of the support frame, a first threaded rod and a second threaded rod are rotatably penetrated through the support frame, the right end of the first threaded rod is fixedly connected to the output end of the motor, and gears are fixedly connected to the left ends of the first threaded rod and the second threaded rod, and the two gears are meshed with each other.

[0010] Further, the measuring mechanism includes a piston assembly, a reset assembly and a detection assembly. Vertical plates are fixedly connected to the front side and the rear side of the support frame, and a plurality of piston assemblies are arranged on the two vertical plates. The piston assembly includes a fixed sleeve fixedly penetrating through the vertical plate, a piston is slidably connected to the inner wall of the fixed sleeve, a piston rod is fixedly connected to the piston, and the end of the piston rod slidably extends to the outside of the fixed sleeve.

[0016] 2. By providing a measuring mechanism, when multiple rollers move past multiple fixed sleeves on two vertical plates, the measuring head contacts the rollers, driving the piston and piston rod to move.

[0027] Please refer to Figure 1-5 As shown, the present invention is a bearing cylindrical roller size measuring device, including a support frame 1 and rollers 4. A moving mechanism 2 and a measuring mechanism 3 are arranged on the support frame 1. The moving mechanism 2 includes a fixing component, a limiting component and a driving component;

[0028] The fixing component includes a moving plate 21 slidably connected to the inner wall of the support frame 1. Two electric cylinders 22 are fixedly connected to the moving plate 21. The output ends of the two electric cylinders 22 are fixedly connected to a top plate 23. A measuring ruler 24 is fixedly connected to the top surface of the moving plate 21. The measuring ruler 24 slidably penetrates through the top plate 23. A plurality of rollers 4 are placed on the top surface of the moving plate 21. The bottom surface of the top plate 23 is in contact with the top surfaces of the plurality of rollers 4. The limiting component includes limiting chutes 29 respectively opened on the front side and the rear side of the moving plate 21. Two limiting sliding rails 291 are fixedly connected to the inner wall of the support frame 1. The inner walls of the two limiting chutes 29 are respectively slidably connected to the two limiting sliding rails 291. The driving component includes a motor 25 fixedly connected to the right side of the support frame 1. A first threaded rod 26 and a second threaded rod 27 are rotatably penetrated through the support frame 1. The right end of the first threaded rod 26 is fixedly connected to the output end of the motor 25. Gears 28 are fixedly connected to the left ends of the first threaded rod 26 and the second threaded rod 27. The two gears 28 mesh with each other. By providing the moving mechanism 2, a plurality of rollers 4 can be clamped and fixed at the same time, avoiding the dislocation of the rollers 4 during the detection and movement, thereby ensuring the accuracy and reliability of the detection results; in addition, such a design can also reduce the detection time, because a plurality of rollers 4 can be clamped and fixed and detected at the same time, and while the rollers 4 are being fixed, the measuring ruler 24 can also measure the height of the rollers 4 at the same time, and the moving plate 21 can move left and right, improving the detection efficiency of the rollers 4 and ensuring the stability of the moving plate 21 during movement, and guaranteeing the accuracy of the detection of the rollers 4.

[0029] The measuring mechanism 3 includes a piston assembly, a reset assembly, and a detection assembly. Vertical plates 31 are fixedly connected to both the front side and the rear side of the support frame 1. A plurality of piston assemblies are provided on each of the two vertical plates 31. The piston assembly includes a fixed sleeve 32 fixedly penetrating through the vertical plate 31. A piston 33 is slidably connected to the inner wall of the fixed sleeve 32. A piston rod 34 is fixedly connected to the piston 33. The end of the piston rod 34 slidably extends to the outside of the fixed sleeve 32. A measuring head 35 is fixedly connected to the end of the piston rod 34. The measuring head 35 is in contact with the roller 4. The reset assembly includes springs 36 wound around a plurality of piston rods 34. One end of the spring 36 is fixedly connected to the fixed sleeve 32, and the other end of the spring 36 is fixedly connected to the measuring head 35. The detection assembly includes connecting pipes 37 communicated with the ends of a plurality of fixed sleeves 32. Pressure sensors 38 are communicated with the ends of a plurality of connecting pipes 37. By providing the measuring mechanism 3, when a plurality of rollers 4 move past the plurality of fixed sleeves 32 on the two vertical plates 31, the measuring head 35 contacts the roller 4, driving the piston 33 and the piston rod 34 to move. At this time, the spring 36 is compressed. Since the arcs at different positions on the roller 4 are different, the displacement distances of the plurality of pistons 33 will also be different. When the piston 33 moves, it will squeeze the air inside the fixed sleeve 32, generating a pressure in the connecting pipe 37. The pressure sensor 38 detects and compares the pressure, and can completely present the pressure levels at different positions on the roller 4, so as to comprehensively measure the outer wall arc of the roller 4. This structure greatly improves the measurement accuracy and reliability of the roller 4, providing important technical support for subsequent product quality control and performance optimization.

[0030] A specific application of this embodiment is that the pressure sensor 38 is a device or apparatus that can sense a pressure signal and convert the pressure signal into a usable output electrical signal according to a certain rule;

[0031] By providing a moving mechanism 2, two electric cylinders 22 and the top plate 23 cooperate with each other. After placing a plurality of rollers 4 on the top surface of the moving plate 21, the plurality of rollers 4 can be clamped and fixed simultaneously, preventing the rollers 4 from being misaligned during the detection movement, thereby ensuring the accuracy and reliability of the detection results. In addition, such a design can also reduce the detection time because the plurality of rollers 4 can be clamped and fixed and detected simultaneously, instead of clamping and fixing and detecting each roller 4 separately, improving the detection efficiency and productivity. At the same time as fixing the rollers 4, the measuring ruler 24 can also measure the height of the rollers 4 simultaneously. The limiting sliding groove 29 and the limiting sliding rail 291 cooperate with each other, enabling the moving plate 21 to only slide left and right on the inner wall of the support frame 1. When the motor 25 drives the first threaded rod 26 to rotate, the two gears 28 cooperate with each other to drive the second threaded rod 27 to rotate relatively. Since the thread directions of the first threaded rod 26 and the second threaded rod 27 are opposite, the moving plate 21 can be driven to move left and right, improving the detection efficiency of the rollers 4 while ensuring the stability of the moving plate 21 during movement and guaranteeing the accuracy of the roller 4 detection.

[0032] By providing a measuring mechanism 3, when a plurality of rollers 4 move past a plurality of fixed sleeves 32 on the two vertical plates 31, the measuring head 35 contacts the rollers 4, driving the piston 33 and the piston rod 34 to move. At this time, the spring 36 is compressed. Since the arcs at different positions on the rollers 4 are different, the displacement distances of the plurality of pistons 33 will also be different. When the piston 33 moves, it will squeeze the air inside the fixed sleeve 32, generating pressure in the connecting pipe 37. The pressure sensor 38 detects and compares the pressure, and can completely present the pressure levels at different positions on the rollers 4, thereby enabling a comprehensive measurement of the outer wall arc of the rollers 4. This structure greatly improves the measurement accuracy and reliability of the rollers 4, providing important technical support for subsequent product quality control and performance optimization. This roller measurement method based on pressure detection can not only quickly and accurately obtain the roller surface shape information, but also avoid damage to the roller surface caused by direct contact, while also greatly reducing the cost and complexity of the measurement.
