Description

Technical Field

[0001] This utility model belongs to the technical field of bearing testing, specifically a bearing inspection tool. Background Technology

[0002] Bearing inspection fixtures are specialized tools or devices used for the precise detection of key bearing parameters (such as inner diameter, outer diameter, width, roundness, geometric tolerances, surface roughness, etc.). They encompass general measuring tools (micrometers, vernier calipers), specialized measuring instruments (inner / outer diameter measuring instruments, profilometers), and automated inspection lines. They sense the geometric features of the bearing surface through contact or non-contact methods, converting minute displacements or optical signals into quantifiable data. Combined with standard comparisons or algorithm analysis, they verify whether the bearing meets design accuracy and quality requirements. They are widely used in sampling inspection, full inspection, and quality arbitration in bearing production lines and are core equipment for ensuring bearing performance and reliability.

[0003] Existing bearing inspection fixtures have certain shortcomings in use. When measuring the outer roundness of bearings, traditional bearing inspection fixtures require the probe to move around the bearing and be manually rotated to get close to the probe structure of the testing instrument for measurement. This makes the bearing inspection process prone to deviation. At the same time, large-diameter bearings increase the difficulty of manual operation and cannot be flexibly applied to the measurement of the outer roundness of bearings of different diameters. Secondly, bearing inspection fixtures are designed for use with outer diameter measuring instruments or profilometers. Traditional bearing inspection fixtures have poor flexibility and cannot arbitrarily adjust the height and position of the testing equipment, which reduces their applicability.

[0004] In summary, the existing technology, which involves manually rotating the bearing to adjust its position and then measuring it near the probe structure of the testing instrument, makes the bearing prone to deviation during testing. Furthermore, large-diameter bearings increase the difficulty of manual operation and cannot be flexibly applied to the measurement of the outer roundness of bearings of different diameters. Utility Model Content

[0005] This utility model provides a bearing inspection fixture that solves the technical problem that manually adjusting the bearing angle by rotating it and then measuring it near the probe structure of the testing instrument can easily lead to deviations during the bearing inspection process. Furthermore, large-diameter bearings increase the difficulty of manual operation and are not flexibly applicable to measuring the outer roundness of bearings of different diameters.

[0006] A bearing inspection fixture includes a fixed base, a mounting bracket, and an auxiliary fixture. The mounting bracket is fixedly installed on the upper outer surface of the fixed base, and the auxiliary fixture is movably sleeved on the inner side of the fixed base. The mounting bracket includes a fixed column and a lifting crossbar. The lifting crossbar is movably installed on one side of the outer surface of the fixed column, and the fixed column and the lifting crossbar are arranged in a cross shape. The auxiliary fixture includes a push-pull rod and a slide. The slide is fixedly installed on the outer surface of one end of the push-pull rod, and a steering seat for mates with the bearing is installed at the upper middle position of the slide.

[0007] As a further technical solution of this utility model, the outer surface of the push-pull rod is movably fitted with a docking slide sleeve, which is fixedly installed on the inner side of the fixed base. The user can drive the slide by pushing and pulling the rod, so that the slide moves the steering seat, thereby adjusting the position of the bearing on the steering seat, so that the outer wall of the bearing is in contact with one side of the probe for inspection. The setting of the docking slide sleeve can improve the stability of the push-pull rod during the pulling operation.

[0008] As a further technical solution of this utility model, a docking head is fixedly installed at the middle position of the lower outer surface of the steering seat, and a groove for use with the docking head is provided at the middle of the upper end of the slide. By using the docking head to connect with the groove, the steering seat can be assembled on the upper end of the slide.

[0009] As a further technical solution of this utility model, a connecting rod is fixedly installed at the middle position of the upper outer surface of the steering seat, and a combination sleeve is fixedly sleeved on the outer surface of the connecting rod. The user can replace the combination sleeve with the corresponding size according to the bearing diameter. The combination sleeve is installed on the connecting rod and uses the combination sleeve to fix the inner side of the bearing.

[0010] As a further technical solution of this utility model, the steering seat and the docking head are movably connected by a shaft. The lower outer surface of the docking head has an arc-shaped structure. By using the shaft, the steering seat can rotate at the upper end of the docking head. When the bearing is close to the probe, the bearing can be rotated by the steering seat to measure the outer wall of the bearing, which replaces the manual rotation of the bearing and improves the measurement accuracy.

[0011] As a further technical solution of this utility model, the upper outer surface of the combined sleeve is inclined, and the upper end of the fixed base is provided with a sliding groove for use with the docking head. The inclined structure can reduce the resistance when the bearing and the combined sleeve are docked.

[0012] As a further technical solution of this utility model, the fixed column and the lifting crossbar are locked together by fastening bolts. The surface of the fixed column is provided with a sliding groove for use with the lifting crossbar. The height of the detector and probe can be adjusted by using the lifting crossbar.

[0013] As a further technical solution of this utility model, a detector is fixedly installed at one end of the lifting crossbar, and a probe is provided at the lower middle of the detector. The detector uses the probe to perform detection operations on parameters such as bearing inner diameter, outer diameter, width, roundness, and geometric tolerance. The detector senses the micro-geometric features of the measured surface through the contact probe and converts the displacement signal into an electrical signal for measurement.

[0014] As a further technical solution of this utility model, one end of the lifting crossbar is provided with a slot for connecting to the detector, and the lifting crossbar and the detector are locked together by a bolt.

[0015] As a further technical solution of this utility model, the fixed column has an overall L-shaped structure, and a clamping plate is provided at the lower end of the fixed column.

[0016] The beneficial effects of this utility model are as follows: By setting up an auxiliary tooling, this utility model provides a bearing rotation auxiliary installation structure when the bearing inspection tooling is used, reducing the deviation when manually rotating the bearing and improving the accuracy of the bearing outer roundness measurement operation. During operation, the user can replace the corresponding size combination sleeve according to the bearing diameter. The combination sleeve is installed on the docking rod and uses the combination sleeve to fix the inner side of the bearing. The bearing to be tested is installed on the steering seat of the auxiliary tooling. The slide can be driven by the push-pull rod, so that the slide drives the steering seat to move, thereby adjusting the position of the bearing on the steering seat to meet the measurement needs of bearings of different sizes. The outer wall of the bearing is placed against one side of the probe. With the setting of the shaft, the steering seat can rotate at the upper end of the docking head. When the bearing is close to one side of the probe, the bearing can be rotated by the steering seat, so that the bearing rotates with the steering seat as the base to measure the outer wall of the bearing, replacing the traditional method of manually rotating the bearing for measurement and improving its measurement accuracy.

[0017] By setting up a mounting bracket, the height of the probe of the testing instrument can be flexibly adjusted when the bearing inspection fixture is used, improving its flexibility during use. The height of the testing instrument and probe can be adjusted by using the lifting crossbar through the sliding groove structure on the surface of the fixed column. The testing instrument uses the probe to detect parameters such as the bearing's inner diameter, outer diameter, width, roundness, and geometric tolerances. The contact probe senses the microscopic geometric features of the measured surface and converts the displacement signal into an electrical signal for measurement. The lifting crossbar and the testing instrument are locked together by a bolt. The testing instrument can be easily replaced through the slot at the end of the lifting crossbar.

The setting of the docking sleeve 11 can improve the stability of the push-pull rod 6 during the pull-out operation.

[0027] A docking head 8 is fixedly installed at the middle of the lower outer surface of the steering seat 12. The upper middle of the slide 7 is provided with a groove for use with the docking head 8. By using the docking head 8 to connect with the groove, the steering seat 12 can be assembled on the upper end of the slide 7.

[0028] The connecting rod 9 is fixedly installed at the middle position of the upper outer surface of the steering seat 12, and the outer surface of the connecting rod 9 is fixedly sleeved with a combination sleeve 10. The user can replace the combination sleeve 10 with the corresponding size according to the bearing diameter.

[0029] The rotating seat 12 and the docking head 8 are movably connected by a shaft 13. The lower outer surface of the docking head 8 has an arc-shaped structure. By using the shaft 13, the rotating seat 12 can rotate at the upper end of the docking head 8. When the bearing is close to the side of the probe 4, the rotating seat 12 can be used to rotate the bearing to measure the outer wall of the bearing, which replaces the manual rotation of the bearing and improves the measurement accuracy.

[0030] The upper outer surface of the combination sleeve 10 has an inclined structure, and the upper end of the fixed base 1 is provided with a sliding groove for use with the docking head 8. The inclined structure can reduce the resistance when the bearing and the combination sleeve 10 are docked.

The combination sleeve 10 is installed on the docking rod 9 and fixes the inner side of the bearing. The bearing to be inspected is installed on the steering seat 12 of the auxiliary fixture 5. The push-pull rod 6 can drive the slide 7, which in turn moves the steering seat 12, thereby adjusting the position of the bearing on the steering seat 12 to meet the measurement needs of bearings of different sizes. The outer wall of the bearing is placed against one side of the probe 4. The setting of the shaft 13 allows the steering seat 12 to rotate at the upper end of the docking clamp 8. When the bearing is close to one side of the probe 4, the steering seat 12 can be used to rotate the bearing to measure the outer wall of the bearing, replacing the traditional method of manually rotating the bearing and improving its measurement accuracy.

[0036] By setting up the mounting bracket 2, the height of the probe 4 of the testing instrument 3 can be flexibly adjusted when the bearing inspection fixture is in use, improving its flexibility. The height of the testing instrument 3 and the probe 4 can be adjusted by using the lifting crossbar 16 through the sliding groove structure on the surface of the fixed column 14. The testing instrument 3 uses the probe 4 to perform testing operations on parameters such as the bearing's inner diameter, outer diameter, width, roundness, and geometric tolerance. The contact probe 4 senses the micro-geometric features of the measured surface and converts the displacement signal into an electrical signal for measurement. The lifting crossbar 16 and the testing instrument 3 are locked together by a bolt. The testing instrument 3 can be easily replaced through the slot 17 at the end of the lifting crossbar 16.
