Description

Technical Field

[0001] The invention relates to the technical field of bearing ring measurement, in particular to a bearing ring groove position testing device. Background Art

[0002] In the actual bearing production and manufacturing work, during the manufacturing process of the ring of the one-way roller locking bearing, it is necessary to measure the groove position of the ring to confirm that its accuracy meets the standard. Because the groove position of the one-way bearing, in order to achieve the one-way locking of the roller, usually requires a circle of completely consistent and equidistantly distributed grooves for roller sliding friction locking. The groove is an inclined arc structure to ensure that the ball has a friction locking effect when rotating in the opposite direction. Because the roller needs to move in the groove, the groove needs a certain length, so the number of rollers is much less than that of traditional bearings, which further increases the requirements for groove accuracy. The accuracy of the groove position of the one-way bearing ring directly affects the accuracy of the one-way bearing, especially for large one-way bearings, its accuracy directly affects the service life. The current bearing ring groove position testing device is not convenient for testing the consistency of the groove radius at the same point of the one-way bearing ring, because the groove position is an arc-shaped inclined structure, and the groove positions at different positions have different corresponding radii. It is difficult to ensure the consistency of the measurement points using traditional measuring tools such as micrometers. At the same time, it is not convenient to prompt at the corresponding groove position in time when the accuracy deviates. It is time-consuming and labor-intensive to observe the data one by one, and it is not convenient to measure the vertical accuracy of the bearing at the same time, and the comprehensiveness of the measurement data is not good.

[0038] The radial measuring device 5 comprises: a radial measuring sliding rod 501, a marking needle 5011 and a pressure spring 502. There are six radial measuring sliding rods 501, and the six radial measuring sliding rods 501 are respectively slidably mounted on the mounting shell 402; the six radial measuring sliding rods 501 are respectively fixedly mounted with marking needles 5011; the tops of the six marking needles 5011 are inclined structures on both sides; the six radial measuring sliding rods 501 are equidistantly distributed on the mounting shell 402; the six radial measuring sliding rods 501 are respectively fixedly mounted with two pressure springs 5 ​​... The ends of the pressure spring 502 on the measuring sliding rod 501 are respectively connected to the outside of the mounting shell 402; the six radial measuring sliding rods 501 are used to radially measure the groove position size on the bearing ring 104 at the same time; the number of radial measuring devices 5 can be increased or decreased according to the adaptability of the groove position on the actual bearing ring 104 during manufacturing; the radial measuring device 5 also includes: a stroke sensor 503 and a conductive bonding column 504, which can use an SDMSS type stroke sensor 503 and a travel display 405 in conjunction with it, and the six radial measuring sliding rods 501 are respectively fixedly sleeved with a stroke sensor 503 and a conductive bonding column 504. sensor 503; six travel sensors 503 are electrically connected to six travel displays 405 respectively; the detection end of the travel sensor 503 is attached to the outside of the measuring mounting column 401; a conductive bonding column 504 is fixedly installed at the bottom of the radial measuring sliding rod 501; the bottom of the conductive bonding column 504 is a conical structure; the conductive bonding column 504 is used to connect to the power control alarm light 404; the joint alarm control part 6 includes: a control ramp block 601, a support spring 602 and a power connection block 603, and the control ramp block 601 is slidably installed on the measuring mounting column 401; on the measuring mounting column 401 A support spring 602 is sleeved; the support spring 602 is connected between the control bevel block 601 and the rotating connecting plate 101; six power connection blocks 603 are embedded on the control bevel block 601; the tops of the six power connection blocks 603 are all bevel structures; the tops of the six power connection blocks 603 are elastically attached to the conductive bonding column 504 respectively; the conductive bonding column 504, the power connection block 603 and the alarm light 404 on the same side are connected in series to a battery power supply, and the battery power supply can be set with a switch; the alarm light 404 is used to indicate that the groove position on the bearing ring 104 is abnormal, and the elastic force of the pressure spring 502 is greater than the support spring 602;The six radial measuring devices 5 can be used to measure the six groove positions on the bearing ring 104 at the same time, which is more efficient. The radial measuring device 5 can always be kept in contact with the bearing ring 104 for detection. The combined alarm control component 6 can be used to energize the radial measuring device 5 for monitoring, which can facilitate the staff to know the deviation of the groove position size and prevent the problem of easy omission of the six stroke displays 405 by manual and tedious observation at the same time. Once there is a deviation in the six groove positions on the bearing ring 104, an alarm can be given, and the staff can then observe the stroke display 405 to observe the specific deviation.

When the standard state is met, the readings displayed by the six stroke displays 405 should be consistent, that is, the radius data of each position of the six groove positions on the bearing ring 104 are consistent. The radial measurement sliding rod 501 at the groove position with a relatively large relative radius deviation, under the pressure of the pressure spring 502, slides outward to adapt to the groove position with a relatively large relative radius deviation, which also drives the conductive fitting column 504 to move outward and separate from the power connection block 603 of the inclined structure. At this time, the alarm light 404 can be disconnected and extinguished to remind the staff that there is a deviation in the groove position here. ;

[0039] Embodiment 2, on the basis of embodiment 1, the groove position vertical measuring piece 7 comprises: a rotating arm 701 and a detection column 702, the rotating arm 701 is rotatably mounted on the front end of the radial measuring sliding rod 501; the detection column 702 is fixedly mounted on the rotating arm 701; the detection column 702 is attached to the groove position on the bearing ring 104; the rotating arm 701 is located in the middle of the detection column 702; the groove position vertical measuring piece 7 also comprises: a V-shaped spring clip 703 and an angle display scale 704, two V-shaped spring clips 703 are fixedly mounted on the detection column 702, and the ends of the two V-shaped spring clips 703 are respectively fixedly mounted on both sides of the radial measuring sliding rod 501; the V-shaped spring clip 703 is used to elastically support the detection column 702; the angle display scale 704 is fixedly mounted on the top of the detection column 702; the top of the angle display scale 704 is provided with an angle scale line; the angle display The upper part of the ruler 704 is an arc-shaped structure; the angle display ruler 704 corresponds to the marking needle 5011; the angle display ruler 704 is used to display the vertical offset angle of the groove position on the bearing ring 104.

The vertical verticality of the groove position can be measured to ensure that the roller can fully fit the groove position after the subsequent roller is installed, thereby improving the stability of the roller locking. The structure is simpler and more reasonable, which can ensure the comprehensiveness of the detection data and directly read the data through the angle display ruler 704. The present structure is more practical. The angle display ruler 704 rotates and can cooperate with the marking needle 5011 for marking and indication. The V-shaped springs 703 on both sides of the detection column 702 can play the role of elastic support.

[0040] The working principle of this embodiment is as follows: first, place the structure on the detection table or the ground, place the bearing ring 104 on the top of the spiral connection tube 103, then tighten and press the threaded tube 201, and press the inclined surface 2011 to fit and squeeze the outer edge of the bearing ring 104 to tighten it; rotate the rotating installation ring 301, press the elevation column 302, so that the elevation column 302 is attached to the end face of the bearing ring 104, and observe the scale line on the elevation column 302 to facilitate the accuracy of the end face of the bearing ring 104; rotate the detection rotating ring 102 to drive the bearing ring 104 to rotate, and detect the rotation The ring 102 is provided with an indicating arrow corresponding to the rotation scale 1011 to observe the rotation angle. At this time, the pressure spring 502 is squeezed, driving the radial measurement sliding rod 501 to push the detection column 702 to stick to the groove position on the bearing ring 104. As the bearing ring 104 rotates, the detection column 702 slides against the groove position on the bearing ring 104. During the process, the six radial measurement sliding rods 501 slide to adapt to the radial changes, and the size data is displayed through the travel display 405. When the bearing ring 104 meets the standard state, the readings displayed by the six travel displays 405 should be consistent, that is, the bearing ring 104 is in the standard state. The radius data of each position of the six grooves on the ring 104 are consistent. The battery power switch corresponding to each alarm light 404 can be turned on when in use. If there is a size deviation in the grooves on the bearing ring 104, the radial position of the six radial measuring sliding rods 501 will deviate. At this time, the radial measuring sliding rods 501 at the grooves with relatively large radius deviations will slide outward under the pressure of the pressure spring 502 to fit the grooves with relatively large radius deviations, thereby driving the conductive fitting column 504 to move outward and separate from the power receiving block 603 of the inclined structure. At this time, the alarm light 404 can be turned off. The road goes out to remind the staff that there is a deviation in the groove position here. At this time, the staff can observe the corresponding travel display 405 to quickly measure defective products; when the detection column 702 is completely in contact with the inner side of the groove position, if the groove position is vertically deviated and skewed, under the elastic extrusion of the pressure spring 502, the detection column 702 can be driven to completely fit the inner side of the groove position. At this time, the detection column 702 will be skewed to adapt to the groove position, driving the angle display ruler 704 to rotate, and cooperate with the marking needle 5011 to mark the indicated angle. The staff can observe the angle reading corresponding to the angle display ruler 704.
