[0002] Bearings are an important component in mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. After the bearings are processed, especially precision bearings, they need to be inspected to ensure their normal use in mechanical equipment after assembly. Therefore, precision bearing inspection equipment is needed.

[0003] However, the existing precision bearing testing equipment still has the following defects during use: 1. Some precision bearing testing equipment cannot flexibly fix bearings of different sizes when fixing the bearings, which reduces the practicality of the equipment. After fixing, it cannot ensure that the jet nozzle used to drive the bearing to rotate is always aligned with the middle of the outer surface of the bearing. Therefore, while driving the bearing to rotate, the bearing will also be subjected to uneven force during rotation, affecting the test results.

During the inspection process, the existing precision bearing inspection equipment is unable to apply corresponding pressure to the precision bearing according to the usage scenario of the precision bearing during the inspection process. Therefore, it is unable to better simulate the operating conditions of the precision bearing. At the same time, it is unable to inspect the precision bearing under different load conditions.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0021] A precision bearing detection device according to a preferred embodiment of the present invention will be described in detail below. Figure 1-Figure 5 As shown, a precision bearing detection equipment includes a base plate 1, a support frame 2 is fixedly installed on the left and right sides of the top of the base plate 1, a mounting frame 3 is fixedly installed on the top of the support frame 2, a limit mounting component 4 is arranged inside the mounting frame 3, and a pressure test component 5 is arranged on the top of the limit mounting component 4.

[0022] Among them, the limit installation component 4 includes a slide rod 41, and the inner side of the installation frame 3 is slidably connected with the slide rod 41. There are two slide rods 41, and the two slide rods 41 are symmetrical front and back and penetrate the left and right side walls of the installation frame 3. The left sides of the two slide rods 41 are bent close to the center, and a threaded sleeve 42 is fixedly installed between the adjacent ends in the center. The middle of the left end of the installation frame 3 is connected to a threaded rod 43 for limited rotation. The threaded rod 43 penetrates the threaded sleeve 42 and is threadedly connected to the threaded sleeve 42, so that when the threaded rod 43 rotates, it can drive the threaded sleeve 42 to move left and right.

[0023] A sleeve rod 44 is fixedly installed in the middle of the left end of the inner side of the installation frame 3, and a spring 45 is fixedly connected between the middle parts of the sleeve rod 44. A cylindrical sleeve 46 is sleeved on the outer side of the spring 45 between the middle parts of the sleeve rod 44. The outer periphery of the middle part of the cylindrical sleeve 46 is evenly slidably connected to a limiting column 47. An extrusion rod 48 is fixedly installed on one end of the outer side of the limiting column 47. A transmission rod 49 is transmission-connected between the left and right sides of the extrusion rod 48 and the outer periphery of the sleeve rod 44. The transmission rod 49 is symmetrically distributed on the left and right sides of the extrusion rod 48, and one end of the transmission rod 49 is hinged to the left and right sides of the extrusion rod 48, and the other side is hinged to the outer periphery of the left and right sides of the sleeve rod 44 after tilting inwards. Therefore, when the sleeve rod 44 is extruded and moved toward the middle, the extrusion rod 48 can be pushed outward at the same time through the transmission rod 49.

[0024] A push plate 410 is fixedly installed between the right sides of the two slide bars 41 . The push plate 410 is located on the inner side of the installation frame 3 and on the right side of the sleeve bar 44 , so that the push plate 410 can follow the slide bar 41 to push the sleeve bar 44 to the left.

[0025] When it is necessary to install bearings of different sizes, the bearing is first placed between the right end of the sleeve rod 44 and the push plate 410, and then the bearing is sleeved on the outside of the sleeve rod 44 from the right side and pushed rightward to the outside of the middle of the extrusion rod 48.

[0026] After the placement is completed, the threaded rod 43 is driven to rotate. During the rotation of the threaded rod 43, the threaded connection between the threaded rod 43 and the threaded sleeve 42 is utilized to drive the threaded sleeve 42 and the sliding rod 41 to move to the left, so that the sliding rod 41 drives the push plate 410 to move to the left. During the movement of the push plate 410 to the left, it can contact the right end of the sleeve rod 44 and push the sleeve rod 44 to move to the left, so that the sleeve rod 44 compression spring 45 is squeezed and moved toward the middle. During the squeezing and moving of the sleeve rod 44 toward each other, the sliding connection of the limit column 47 at one end of the extrusion rod 48 on the outer periphery of the cylindrical sleeve 46 can enable the transmission rod 49 to push the extrusion rod 48 to move outward at the same time, thereby squeezing and fixing the bearing from the inside to complete the installation of the bearing.

[0027] After the detection is completed, the sliding rod 41 and the push plate 410 are moved to the right by rotating the threaded rod 43 until the distance between the push plate 410 and the right end of the sleeve rod 44 is greater than the thickness of the bearing. While the push plate 410 moves to the right, the sleeve rod 44 also moves to the right under the action of the spring 45, and then the extrusion rod 48 is pulled toward the center through the transmission rod 49 to release the limit on the bearing, push the bearing to the right, and take it out from the gap between the push plate 410 and the right end of the sleeve rod 44.

[0028] Furthermore, if Figure 1 , Figure 6-Figure 8As shown, the pressurized test assembly 5 includes a slide seat 51, and the slide seat 51 is symmetrically and slidably connected to the front and rear sides of the top of the mounting frame 3, the top of the rear slide seat 51 is rotationally connected to the rear hinge rod 52, the front side of the rear hinge rod 52 is rotationally connected to the front hinge rod 53, a screw rod 54 is fixedly installed in the middle of the front side end of the front hinge rod 53, and the top of the front slide seat 51 is rotationally connected to the rotating block 55, a through circular hole is provided inside the rotating block 55, the screw rod 54 passes through the circular hole, and the outer side of the screw rod 54 is threadedly connected to a nut 541, the nut 541 is located on the side of the rotating block 55 away from the front hinge rod 53, so the downward position of the rear hinge rod 52 and the front hinge rod 53 can be adjusted by the nut 541.

[0029] The bottom of the rear hinged rod 52 is slidingly connected to a mounting seat 56, and the bottom of the mounting seat 56 is rotatably connected to a roller 57. There are two rollers 57, which are symmetrically distributed at the bottom of the mounting seat 56 so that the rollers 57 can be better squeezed and attached to the outer ring surface of the bearing. A limited alignment component 58 is set between the two sides and the top of the mounting seat 56.

[0030] A threaded rod 59 is fixedly installed in the center of the top of the mounting seat 56. The threaded rod 59 penetrates the rear hinge rod 52 upward and is slidably connected to the rear hinge rod 52. The outer side of the threaded rod 59 is threadedly connected to a fastening seat 510. The fastening seat 510 is located above the rear hinge rod 52. Therefore, the position of the mounting seat 56 can be fixed by screwing the fastening seat 510. The inner side of the front hinge rod 53 is limitedly slidably connected to a connecting block 511. A downward nozzle is installed in the middle of the connecting block 511, and a socket connected to the air compressor through a hose is installed on the top of the nozzle. The high-pressure gas is sprayed by the nozzle to drive the bearing to rotate. Probes for detection are arranged on both sides of the nozzle in the middle of the connecting block 511, and a socket for electrical connection is arranged on the top of the probe to facilitate the electrical connection of the probe with the information collection and processing equipment.

[0031] A sleeve 512 is movably sleeved on the outer side of the rear sliding rod 41, and an elastic support rod 513 is fixedly installed on the outer periphery of the sleeve 512. The end of the elastic support rod 513 away from the sleeve 512 is hinged to the bottom of the rear side of the rear hinge rod 52, thereby elastically supporting the rear hinge rod 52.

[0032] After the installation of the bearing is completed and the bearing needs to be tested, the pressurized test assembly 5 is first moved to the top of the bearing by using the limited sliding connection of the slide seat 51 on the front and rear sides of the top of the installation frame 3, and then the rear hinge rod 52 and the front hinge rod 53 are driven by pulling the screw rod 54 to compress the elastic support rod 513 and press it down. During the downward pressing process, the position of the mounting seat 56 is adjusted by the limited sliding connection of the mounting seat 56 at the bottom of the rear hinge rod 52, so that the two rollers 57 at the bottom of the mounting seat 56 can be attached to the outer ring surface of the bearing after being pressed down. After the adjustment is completed, the threaded connection between the threaded rod 2 59 and the fastening seat 510 is used to fix the position of the mounting seat 56 by tightening the fastening seat 510.

[0033] After the two rollers 57 are attached to the outer ring surface of the bearing, the nut 541 is threadedly connected to the screw rod 54 to rotate the nut 541 until it is attached to the end surface of the rotating block 55, thereby limiting the position of the rear hinge rod 52 and the front hinge rod 53, and then adjusting the position of the connecting block 511 so that the nozzle in the middle of the connecting block 511 is tilted toward the outer ring surface of the bearing. After the nozzle sprays high-pressure gas, it can drive the bearing to rotate, and then cooperate with the probe on the connecting block 511 to detect the rotation state of the bearing.

[0034] By controlling the pressure of the high-pressure gas sprayed from the nozzle, the speed of the driving bearing rotation can be adjusted, thereby realizing the detection of the bearing at different rotation speeds. By continuing to rotate the nut 541, the nut 541 can give the rear hinge rod 52 a greater downward pressure with the help of the reaction force of the rotating block 55, thereby realizing the adjustment of the downward pressure of the bearing by the two rollers 57 to detect the bearing under different load conditions. At the same time, it can also better simulate the operating conditions of precision bearings to detect the bearings, thereby improving the comprehensiveness of the detection.

[0035] After the detection is completed, by reversing the nut 541, the rear hinge rod 52 will drive the front hinge rod 53 to arch upward under the action of the elastic support rod 513, thereby separating the roller 57 from the bearing, making it easier to remove the bearing.

[0036] Furthermore, if Figure 8-Figure 10As shown, the limit alignment component 58 includes a lower limit seat 581, and the lower limit seats 581 are fixedly installed on the left and right ends of the mounting seat 56, and fixed rods 582 are symmetrically fixedly installed on the left and right sides of the top of the mounting seat 56, and the fixed rods 582 penetrate the rear hinge rod 52 upward and are slidably connected with the rear hinge rod 52, and a fixed frame 583 is fixedly installed on the top of the fixed rod 582, and an upper limit seat 584 is fixedly installed on the top of the fixed frame 583, and a cylindrical sleeve 585 is symmetrically limited and slidably connected on the left and right sides between the upper limit seat 584 and the lower limit seat 581, and a telescopic rod 586 is connected to the inner limit sliding connection at the bottom of the cylindrical sleeve 585, and the bottom periphery of the cylindrical sleeve 585 is provided with fastening bolts for fixing the telescopic rod 586, thereby realizing the adjustment of the extension length of the telescopic rod 586.

[0037] The bottom ends of the telescopic rods 586 are fixedly mounted with extrusion blocks 587 , and the extrusion blocks 587 on the left and right sides extend toward the adjacent side. An extrusion adjustment component 588 is disposed inside the fixed frame 583 .

[0038] Furthermore, if Figure 10-11 As shown, the extrusion adjustment component 588 includes a threaded rod 5881, the internal front and rear limiting rotation connection of the fixed frame 583 is connected with the threaded rod 5881, the outer front and rear sides of the threaded rod 5881 are connected with two threaded sleeves 5882, the front and rear threads of the outer periphery of the threaded rod 5881 are opposite, and are respectively threadedly connected with the threaded sleeves 5882 on the front and rear sides. Therefore, when the threaded rod 5881 rotates, it can drive the threaded sleeves 5882 on the front and rear sides to move toward or away from each other.

[0039] The left and right sides of the fixed frame 583 are symmetrically slidably connected with connecting columns 5883, and the connecting columns 5883 on the left and right sides are respectively fixedly installed with the cylindrical sleeves 585 on the left and right sides. A transmission rod 5884 is transmission-connected between the left and right sides of the threaded sleeve 5882 and the connecting columns 5883. One end of the transmission rod 5884 is hinged to the left and right sides of the threaded sleeves 5882 on the front and rear sides, and the other end is symmetrically inclined toward the middle and then hinged to one side of the connecting columns 5883 on the left and right sides located inside the fixed frame 583. Therefore, when the threaded sleeves 5882 move toward each other, the connecting columns 5883 can be pushed to move to both sides, and when the threaded sleeves 5882 move away from each other, the connecting columns 5883 can be pulled to move toward the middle.

[0040] After the two rollers 57 are attached to the outer ring surface of the bearing, before driving the bearing to rotate for detection, the telescopic rod 586 is pulled downward to move the extrusion block 587 to the two sides of the inner ring of the bearing. After the extrusion block 587 is aligned with the two sides of the inner ring of the bearing, the position of the telescopic rod 586 is fixed by tightening the bolts.

[0041] After the fixation is completed, by rotating the threaded rod 3 5881, utilizing the threaded connection between the threaded rod 3 5881 and the threaded sleeve 2 5882, and the design of the opposite outer threads on the front and rear sides of the threaded rod 3 5881, the threaded sleeves 2 5882 on the front and rear sides can be driven to move away from each other, and then the connecting column 5883 can be driven to move toward the middle under the action of the transmission rod 2 5884, and the fixed installation of the connecting column 5883 and the cylindrical sleeve 2 585, and the limited sliding connection of the cylindrical sleeve 2 585 between the lower limit seat 581 and the upper limit seat 584, the cylindrical sleeve can be driven to move. The second 585 moves toward the middle, thereby driving the telescopic rod 586 and the extrusion block 587 to move toward the middle, so that the extrusion block 587 is pressed and attached to the two ends of the inner ring of the bearing, so that the bearing is always in the central position below the rear hinge rod 52 and the front hinge rod 53 during the detection process, and then after the rear hinge rod 52 is pressed down, the roller 57 can always press down the bearing evenly, and the nozzle on the front hinge rod 53 can always be in the central position of the outer wall surface of the bearing. Therefore, in the process of blowing the bearing to rotate, the bearing is also subjected to uniform force, thereby ensuring the accuracy of the detection result.

[0042] After the inspection is completed, the extrusion block 587 is expanded to both sides by reversing the threaded rod 5881 to release the extrusion on the inner ring of the bearing, and then the telescopic rod 586 is retracted upward to facilitate the removal of the bearing.

[0043] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
