Description

Technical Field

[0001] This utility model relates to the field of bearing ring testing technology, specifically a bearing ring testing device. Background Technology

[0002] Bearing rings are ring-shaped parts of radial rolling bearings with one or more raceways. Bearing rings can support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. With the development of technology, the demand for bearing rings is increasing, and people are paying more and more attention to the inspection of bearing rings.

[0003] In the prior art, the authorized patent with publication number CN221666788U discloses a bearing ring detection device, including a base plate. A transmission groove is provided on the top of the base plate. An electric telescopic rod is fixedly installed on the inner side wall of the transmission groove. A support plate is slidably installed inside the transmission groove. The telescopic end of the electric telescopic rod is fixedly connected to the side wall of the support plate. A detection mechanism is provided above the side wall of the support plate. A fixing frame is fixedly connected to the top of the base plate. A sliding groove is provided on the side wall of the fixing frame facing the support plate. A clamping mechanism is provided inside the sliding groove. This invention improves upon the traditional method of clamping only two sides of the bearing ring by setting a clamping mechanism and adjusting the position of the limiting block according to the thickness of the bearing ring, thus ensuring the tightness of the clamping.

[0004] The above technical solution still has the following shortcomings when in use: the above device can only detect the inner ring of the bearing race and cannot detect the outer ring of the bearing race, which has low practicality. In this regard, we propose a bearing race detection device to solve the above problems. Utility Model Content

An installation block is provided on the portal frame. A rotating shaft is rotatably mounted on the bottom wall of the installation block. A roller is fixedly mounted on the rotating shaft.

[0008] Preferably, a servo motor is fixedly mounted on one end of the rotating seat, and the output end of the servo motor is driven by a second bidirectional screw, and both second moving rods are threadedly connected to the second bidirectional screw.

[0009] Preferably, sliding rods are fixedly welded to both sides of the mounting block, and the two sliding rods are slidably connected to the two sides of the portal frame. Springs are sleeved on the sliding rods, and the two ends of the springs are fixedly connected to the portal frame and the mounting block, respectively.

[0010] Preferably, pressure sensors are fixedly installed on both sides of the gantry frame, with the sensing part of the pressure sensor close to the end of the slide rod. An alarm is fixedly installed on the front side wall of the rotating seat, and the alarm is electrically connected to the pressure sensor via a wire.

[0011] Preferably, a support plate is fixedly installed on the adjusting seat, and a sliding groove is formed on the support plate, in which the two first moving rods are slidably connected.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] 1. This utility model, through the cooperation of components such as the adjustment seat, servo motor, first bidirectional screw, moving seat, first moving rod and pressure block, can clamp the inner or outer wall of the bearing ring. Through the cooperation of the rotating seat, servo motor, second bidirectional screw and second moving rod, the two rollers can be adjusted to fit against the inner or outer wall of the bearing ring, so that the device can detect the inner or outer wall of the bearing ring, which greatly improves the practicality of the device.

[0014] 2. The roller of this utility model is mounted on the gantry frame via a mounting block and two sliding rods, and is positioned by a spring. If the bearing ring being tested is unqualified, the roller will move the mounting block, which in turn will cause the sliding rods to slide, squeezing the pressure sensor and triggering an alarm. If the bearing ring is qualified, the sliding rods will not squeeze the pressure sensor and will not trigger an alarm. Compared to the method of identifying whether the bearing ring is qualified by observing the movement of the movable rod, the test results of this utility model are more accurate.

[0022] Please see Figure 1-5This utility model provides a technical solution: a bearing ring testing device, comprising:

[0023] A bottom mounting base 1 has a support base 2 fixedly welded to its top wall. An adjusting base 3 is fixedly welded to the front side wall of the support base 2 near its bottom end. A servo motor 4 is fixedly mounted on the front end of the adjusting base 3. The output end of the servo motor 4 is connected to a first bidirectional screw 5, which is rotatably mounted on the adjusting base 3. Two movable seats 6 are threaded onto the first bidirectional screw 5. A first movable rod 7 is fixedly welded to the top wall of each movable seat 6. Two symmetrically arranged pressure blocks 8 are fixedly welded to the top of the first movable rod 7. A fixed base 9 is fixedly welded to the top of the support base 2. An electric telescopic rod 10 is fixedly installed on the fixed base 9. An installation rod 11 is fixedly installed at the bottom end of the electric telescopic rod 10. A low-speed motor 12 is fixedly installed on the top wall of the installation rod 11 near the front end. The output end of the low-speed motor 12 is connected to a rotating rod 13. A rotating seat 14 is fixedly welded to the bottom end of the rotating rod 13. Two symmetrically arranged second moving rods 15 are provided on the rotating seat 14. A portal frame 16 is fixedly welded to the bottom end of the second moving rod 15. An installation block 17 is provided on the portal frame 16. A rotating shaft 18 is rotatably installed on the bottom wall of the installation block 17. A roller 19 is fixedly installed on the rotating shaft 18.

[0024] A servo motor 20 is fixedly mounted on one end of the rotating seat 14. The output end of the servo motor 20 is connected to a second bidirectional screw 21. Both second moving rods 15 are threaded onto the second bidirectional screw 21. The servo motor 20 can drive the second bidirectional screw 21 to rotate, thereby adjusting the distance between the two second moving rods 15.

[0025] Slide rods 22 are fixedly welded to both sides of the mounting block 17. The two slide rods 22 are slidably connected to the two sides of the portal frame 16. Springs 23 are sleeved on the slide rods 22. The two ends of the springs 23 are fixedly connected to the portal frame 16 and the mounting block 17, respectively. When the roller 19 is inspecting the bearing ring, if the bearing ring is unqualified, the roller 19 will drive the mounting block 17 to move, thereby driving the slide rods 22 to slide.

[0026] Pressure sensors 24 are fixedly installed on both sides of the gantry frame 16. The sensing part of the pressure sensor 24 is close to the end of the slide rod 22. An alarm 25 is fixedly installed on the front side wall of the rotating seat 14. The alarm 25 is electrically connected to the pressure sensor 24 through a wire. When the pressure sensor 24 senses pressure, it can trigger an alarm sound through the alarm 25.

[0027] A support plate 26 is fixedly installed on the adjusting seat 3. A sliding groove 27 is provided on the support plate 26. Both first moving rods 7 are slidably connected in the sliding groove 27. The support plate 26 is used to place the bearing rings.

[0028] Working principle: When using this utility model, the bearing ring to be tested is placed on the support plate 26. The servo motor 4 is started, driving the first bidirectional screw 5 to rotate, causing the two first moving rods 7 to move, driving the pressure block 8 to press against the inner and / or outer wall of the bearing ring. Then, the electric telescopic rod 10 is started, causing the two rollers 19 to move to the bearing ring position. The servo motor 20 drives the second bidirectional screw 21 to rotate, adjusting the two second moving rods 15 so that the two rollers 19 are in contact with the outer or inner wall of the bearing ring. Then, the low-speed motor 12 is started, driving the rotating seat 14 to rotate at low speed, thereby causing the two rollers 19 to rotate around the bearing ring. If the bearing ring is unqualified, the rollers 19 will drive the mounting block 17 to move, thereby causing the slide rod 22 to slide and squeeze the pressure sensor 24, causing the alarm 25 to sound an alarm. If the bearing ring is qualified, the slide rod 22 will not squeeze the pressure sensor 24, and no alarm will sound.
