Description

Technical Field

[0001] This utility model relates to the field of bearing inner and outer diameter detection technology, and in particular to a bearing inner and outer diameter detection device. Background Technology

[0002] Bearings are essential basic components of various mechanical equipment. Their precision, performance, lifespan, and reliability play a decisive role in the precision, performance, lifespan, and reliability of the host machine. Rolling bearings generally consist of four parts: outer ring, inner ring, rolling elements, and cage. According to the shape of the rolling elements, rolling bearings are divided into two main categories: ball bearings and roller bearings.

[0003] When using the above technology, the following technical problems were found in the existing technology: on the one hand, the limiting mechanism is difficult to flexibly adapt to bearings of different diameters, which makes the bearings prone to displacement during the detection process, affecting the detection accuracy; on the other hand, the measuring mechanism cannot well take into account the measurement of the inner and outer sides and diameter of bearings of different diameters, requiring frequent replacement of measuring tools or adjustment devices, which is cumbersome and reduces the detection efficiency. To this end, we designed a bearing inner and outer diameter detection device to provide another technical solution to the above technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a bearing inner and outer diameter detection device to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A bearing inner and outer diameter detection device includes a base, a support plate fixed to one end of the top of the base, guide grooves formed at all four ends of the inner side of the support plate, arc-shaped clamps slidably connected to the inner side of the guide grooves, bearings assembled at the ends of the four arc-shaped clamps that are close to each other, a U-shaped slide block slidably connected to the other end of the top of the base, a U-shaped telescopic frame slidably connected to both sides of the top of the U-shaped slide block, scale guide rods fixed to both sides of the top of the U-shaped telescopic frame, an end needle slidably connected to the outer side of the scale guide rods, and a starting needle fixed to one end of the top of the U-shaped telescopic frame.

[0007] The support plate has an adjustment mechanism at one end for driving four arc-shaped clamps. The adjustment mechanism includes a servo motor, a linkage rod, and a transmission disk. A U-shaped frame is fixed to one end of the support plate. A servo motor is fixed to the inner side of the U-shaped frame. A transmission disk is fixed to the output end of the servo motor. A linkage rod is rotatably connected to the outer side of the transmission disk. The end of the linkage rod away from the transmission disk is rotatably connected to the arc-shaped clamps.

[0008] The connection point between the linkage rod and the transmission disc is offset from the center of the transmission disc.

[0009] The inner side of the guide groove is fixed with a guide rod, and the outer side of the guide rod is slidably connected to the arc-shaped clamping plate. Anti-slip pads are fixed at the ends of the four arc-shaped clamping plates that are close to each other.

[0010] The top of the U-shaped slide is equipped with an electric push rod, and the output end of the electric push rod is fixed to the U-shaped telescopic frame.

[0011] The top of the U-shaped telescopic frame is rotatably connected to an adjusting screw, and the outer side of the adjusting screw is threaded to the final needle.

[0012] The U-shaped slide has L-shaped blocks fixed on both sides, and pins are slidably connected inside the L-shaped blocks. Several limiting holes are opened at the other end of both sides of the base, and one end of the pin is slidably connected to the corresponding limiting hole.

[0013] It is clear without a doubt that the technical solution described above in this application can solve the technical problem that this application aims to address.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the adjustment mechanism composed of a servo motor, a transmission disk and a linkage rod can drive four arc-shaped clamping plates to slide synchronously, which can clamp and limit bearings of different diameters, thus expanding the applicability of the device.

[0015] The U-shaped slide is fixed by the engagement of the pin with the limiting hole of the base, which prevents the displacement of the U-shaped slide during the measurement process; the arc-shaped clamp slides along the guide rod and guide groove, which ensures the stability when clamping; the final needle moves under the guidance of the scale guide rod, which ensures the accuracy of the measurement position and improves the stability of the measurement process in many ways.

[0016] The electric push rod allows for quick adjustment of the needle's starting position, the adjusting screw precisely controls the movement of the final needle, and the scale guide rod directly displays the measurement results, simplifying the operation steps and improving testing efficiency.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a bearing inner and outer diameter detection device, including a base 1, a support plate 2 fixed to one end of the top of the base 1, guide grooves 6 are provided at all four ends of the inner side of the support plate 2, arc-shaped clamps 8 are slidably connected to the inner side of the guide grooves 6, bearings are assembled at the ends of the four arc-shaped clamps 8 that are close to each other, a U-shaped slide 11 is slidably connected to the other end of the top of the base 1, a U-shaped telescopic frame 12 is slidably connected to both sides of the top of the U-shaped slide 11, scale guide rods 17 are fixed to both sides of the top of the U-shaped telescopic frame 12, a final needle 15 is slidably connected to the outer side of the scale guide rods 17, and a starting needle 16 is fixed to one end of the top of the U-shaped telescopic frame 12;

[0026] When measuring bearings of different diameters, the bearing is placed between four arc-shaped clamps 8 for clamping and limiting. The sliding U-shaped slide 11 drives the U-shaped telescopic frame 12, scale guide rod 17, end needle 15, and starting needle 16 to measure the bearing. The electric push rod 13 is activated to drive the U-shaped telescopic frame 12 and starting needle 16 to the starting point of the bearing measurement. Then, the adjusting screw 14 is rotated to drive the end needle 15 to adjust along the guide of the scale guide rod 17. The starting needle 16 effectively serves as the end point of the bearing measurement. Finally, the distance between the end needle 15 and the starting needle 16 is displayed by the scale lines on the outside of the scale guide rod 17, thereby improving the stability and practicality of bearing measurement.

[0027] One end of the support plate 2 is provided with an adjustment mechanism for driving four arc-shaped clamps 8. The adjustment mechanism includes a servo motor 5, a linkage rod 9 and a transmission disk 10. A U-shaped frame 3 is fixed to one end of the support plate 2. A servo motor 5 is fixed to the inner side of the U-shaped frame 3. A transmission disk 10 is fixed to the output end of the servo motor 5. A linkage rod 9 is rotatably connected to the outer side of the transmission disk 10. The end of the linkage rod 9 away from the transmission disk 10 is rotatably connected to the arc-shaped clamp 8 respectively. The connection point between the linkage rod 9 and the transmission disk 10 is offset from the center of the transmission disk 10.

[0028] Specifically, by starting the servo motor 5, the transmission disk 10 is rotated, and the transmission disk 10 drives the four linkage rods 9 and the arc-shaped clamping plate 8 to clamp and limit the bearing along the guide rod 7 and the guide groove 6, thereby effectively limiting and positioning bearings of different diameters.

[0029] A guide rod 7 is fixed to the inner side of the guide groove 6, and the outer side of the guide rod 7 is slidably connected to the arc-shaped clamping plate 8. Anti-slip pads are fixed to the ends of the four arc-shaped clamping plates 8 that are close to each other; the anti-slip pads effectively prevent the bearing from slipping or protect it.

[0030] The top of the U-shaped slide block 11 is equipped with an electric push rod 13. The output end of the electric push rod 13 is fixed to the U-shaped telescopic frame 12. The middle of the top of the U-shaped telescopic frame 12 is rotatably connected to an adjusting screw 14. The outer side of the adjusting screw 14 is threadedly connected to the final needle 15.

[0031] Furthermore, by activating the electric push rod 13, the U-shaped telescopic frame 12 and the starting needle 16 are adjusted according to the bearing measurement position. The starting needle 16 serves as the starting point for bearing measurement. Then, the adjusting screw 14 is rotated to drive the ending needle 15 to adjust the end point of the bearing along the guide rod 17. The measurement distance between the starting needle 16 and the ending needle 15 is displayed by the guide rod 17.

[0032] Both sides of the U-shaped slide block 11 are fixed with L-shaped blocks. The L-shaped blocks are slidably connected with pins 4. Several limiting holes are opened at the other ends of both sides of the base 1. One end of the pin 4 is slidably connected to the corresponding limiting hole. By sliding the U-shaped slide block 11, the U-shaped telescopic frame 12, electric push rod 13, end needle 15, starting needle 16, scale guide rod 17 and pin 4 are adjusted towards the bearing. At this time, the end needle 15 and the starting needle 16 measure the bearing. Then, the pin 4 slides with the corresponding limiting hole, thereby increasing the stability and accuracy of the measurement between the end needle 15 and the starting needle 16.

[0033] The usage process of the bearing inner and outer diameter detection device provided by this utility model is as follows:

[0034] The bearing to be tested is placed between four arc-shaped clamps 8. The servo motor 5 is started, and its output end drives the transmission disk 10 to rotate. Since the connection point between the linkage rod 9 and the transmission disk 10 is off-center, the transmission disk 10 will pull the arc-shaped clamps 8 through the four linkage rods 9, so that the arc-shaped clamps 8 slide along the guide rod 7 in the guide groove 6, and finally clamp the bearing to a limit position. The anti-slip pad on the arc-shaped clamps 8 can enhance the fixing effect on the bearing and avoid damage to the bearing surface.

[0035] Then, the electric push rod 13 is activated, and its output end pushes the U-shaped telescopic frame 12 to move, so that the starting needle 16 is aligned with the bearing measurement starting point. Then, the adjusting screw 14 is rotated. Since the final needle 15 is threadedly connected to the adjusting screw 14 and sleeved on the scale guide rod 17, the final needle 15 will slide along the scale guide rod 17 to the bearing measurement endpoint. At this time, the distance between the starting needle 16 and the final needle 15 is directly displayed through the scale line on the outside of the scale guide rod 17, which is the inner and outer diameter of the bearing.

[0036] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
