Description
TECHNICAL FIELD
[0001] The application belongs to the field of bearing cage detection, and particularly relates to a detection tool and method for the pressing slope depth of a self-aligning roller bearing cage. BACKGROUND
[0002] A bearing generally comprises an outer ring, an inner ring, rollers, a cage and the like, the cage is provided with a plurality of windows, and a window beam is arranged between two adjacent windows to separate the windows. During assembly, the rollers are assembled in the windows of the cage. The self-aligning roller bearing cage has a constant inclination angle, and the cage pocket has a high technical content and a comprehensive feature of spherical self-aligning and tapered roller cage. During processing of the cage, the two sides of the window beam of the cage are usually subjected to slope pressing treatment to form a slope surface, so that the edge of the window beam is an inclined surface. After assembly, the rollers are in contact with the slope surface, so that the rollers do not have the phenomenon of being stuck during rotation of the bearing, and the rotation is smooth. The slope pressing process mainly determines the size of the cage pocket and the rotation of the bearing. Since the structure of the cage pocket is special and the shape of the roller is complex, the slope surface directly determines whether the rotation of the bearing meets the design requirements. Therefore, the slope pressing process is a key process for controlling the cage.
[0003] The slope pressing process is completed on a pressing machine. The first qualified cage pressed is set as a first piece, and the subsequently processed cages are subjected to sampling inspection according to the radial runout and rotation flexibility of the first piece. In mass production, the mold needs to be replaced at any time due to consumption or damage. During the consumption and replacement of the mold, the pressing slope depth changes due to the difference in the size of the mold parts. The existing device and method for checking the radial runout and rotation flexibility have low efficiency and cannot accurately measure the real size of the change in the pressing slope depth. The inconsistent pressing slope depth in the same batch of products cannot be detected. The cages are checked according to the existing technical conditions for radial runout and rotation flexibility, and the results meet the process requirements. In particular, there is no obvious difference in the radial runout, and the radial runout is within the required range. The existing pressing slope depth detection tool has low detection precision and cannot guarantee the consistency of the depth of the batch of cages to be detected. Therefore, the existing technology needs to be further improved and enhanced. SUMMARY

[0045] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present application. Therefore, the drawings and the description are considered to be essentially exemplary rather than limiting.
[0046] The present application is described below in conjunction with the drawings of the specification.
[0047] The specific solutions adopted are:
[0048] As Figures 1-6As shown, the application provides a roller bearing cage pressure slope depth detection tool, which comprises a first detection piece 1, a second detection piece 2 and a displacement measuring piece 3. The first detection piece 1 and the second detection piece 2 are arranged in line and can move relative to each other. In the case that both the first detection piece 1 and the second detection piece 2 can move or only one of them moves, the other is fixed, the first detection piece 1 and the second detection piece 2 are provided with an initial position. During detection, the first detection piece 1 and the second detection piece 2 are located in the two opposite window holes of the cage and can abut against the pressure slope surface 70 of the window beam. The displacement measuring piece 3 can measure the displacement change amount of the first detection piece 1 and the second detection piece 2 relative to the initial position, so as to determine the consistency of the pressure slope depth of the to-be-detected cage.
[0049] In the embodiment, the initial position is the position of the qualified pressure slope depth. Specifically, the first detection piece 1 and the second detection piece 2 detect the standard roller bearing cage, and the first detection piece 1 and the second detection piece 2 are respectively located in the two opposite window holes of the standard cage and abut against the pressure slope surface 70 opened in the window beam. At this time, the positions of the first detection piece 1 and the second detection piece 2 are the standard depth positions. Next, the first detection piece 1 and the second detection piece 2 are respectively located at the pressure slope surface 70 positions of the two opposite window holes of the to-be-detected roller bearing cage 7. If the first detection piece 1 and the second detection piece 2 are located at the initial position, the displacement measuring piece 3 does not measure the displacement change amount, and it is determined that the pressure slope depth of the to-be-detected cage is consistent. If the first detection piece 1 and the second detection piece 2 are located outside the initial position, the displacement measuring piece 3 can measure the displacement change amount. If the displacement change amount is within a reasonable error range, it is still determined that the pressure slope depth is consistent. If the displacement change amount exceeds the error range, it is determined that the pressure slope depth is inconsistent.
[0050] As a preferred embodiment of the application, as shown in the drawings, Figure 1 The first detection piece 1 and the second detection piece 2 are a first disc 10 and a second disc 20 with appropriate size and shape. The first disc 10 and the second disc 20 are arranged at the same height. The first disc 10 or the second disc 20 contacts the pressure slope surface 70 point or line of the window beam on both sides of the window hole of the to-be-detected roller bearing cage 7. When the pressure slope depth changes, it is roughly divided into two cases: the pressure slope depth and the pressure slope shallow. In the two cases, the contact points of the first disc 10 and the second disc 20 with the pressure slope surface 70 change, so that the first detection piece 1 or the second detection piece 2 which can move moves, and the displacement measuring piece 3 measures, thereby improving the detection accuracy.
[0051] Considering that the pressure slope surface 70 depth of multiple window holes needs to be measured repeatedly, in the embodiment, the first disc 10 or the second disc 20 is connected with a translation reset mechanism 4. After the detection of the pressure slope surface 70 of the previous window hole is completed, the translation reset mechanism 4 enables the first disc 10 or the second disc 20 to be located outside the initial position or to return to the initial position, thereby facilitating the detection of the next window hole and improving the detection efficiency.
[0052] The specific structure of the translation reset mechanism 4 is shown in Figure 5 The translation reset mechanism 4 includes a sliding block 40, a sliding rail 41, a reset spring 42, and a limiting plate 43. The sliding block 40 is connected to the sliding rail 41, one end of the reset spring 42 is connected to the sliding block 40, and the other end is connected to the limiting plate 43. The first disc 10 or the second disc 20 is arranged on the sliding block 40.
[0053] Considering that the actual unqualified pressure slope 70 depth is very close to the standard pressure slope 70 depth, the movement distance of the first detection piece 1 or the second detection piece 2 is also in a very small range, therefore, the reset spring 42 can be selected as a short spring. After slight compression, the reset spring 42 can quickly recover the deformation. The movement distance of the first detection piece 1 or the second detection piece 2 is limited by the limiting plate 43, and the structure design is reasonable.
[0054] The arrangement mode of the first disc 10 and the second disc 20 can adopt one of the following embodiments:
[0055] In embodiment 1, the second disc 20 or the first disc 10 is fixed relative to the first disc 10 or the second disc 20, as shown in Figure 5 The first disc 10 is connected to the translation reset mechanism 4, and the second disc 20 is fixed as a positioning side. The displacement measuring piece 3 can only measure the displacement change of the movable first disc 10. Specifically, during measurement, the second disc 20 is located outside the self-aligning bearing and abuts against the window beam facing the bearing outer ring surface, and the first disc 10 is located inside the self-aligning bearing 7 and abuts against the pressure slope 70 of the window beam, so that the placement position of the self-aligning bearing can be kept consistent, the detection accuracy is improved, and the depth of the pressure slope 70 can be quickly known.
[0056] In this embodiment, the displacement measuring piece 3 is a linear displacement sensor, and the linear displacement sensor is connected to the digital display table 30 to display the displacement. Specifically, the linear displacement sensor is a pull rod displacement sensor, the pull rod of the pull rod displacement sensor is connected to the sliding block 40 of the translation reset mechanism 4, the sliding block 40 moves to drive the pull rod to displace, so as to detect the displacement change, and the displacement change is displayed through the digital display table 30.
[0057] Further, in order to facilitate use, a placement table 8 is further included, and the first detection piece 1, the second detection piece 2, and the digital display table 30 are arranged on the placement table 8.
[0058] Specifically, the first disc 10 of the first detection piece 1 is sequentially provided below with an equal-height column 5011, a cushion block 12, a second nut seat 13, the second nut seat 13 is provided with a sliding part 14 on one side, the sliding part 14 is connected with a moving slide rail 4115, the moving slide rail 4115 is provided with a plurality of positioning holes 16, a bolt passes through the positioning holes 16 and is connected with a positioning plate 17, when the positioning plate 17 is connected below the placement table 8, the moving slide rail 4115 remains fixed, the equal-height column 5011 is arranged to enable the second disc 20 and the first disc 10 to be located at the same height, the placement table 8 is provided with a through groove 80, and the equal-height column 5011 and the column 50 pass through the through groove 80 to arrange the first disc 10 and the second disc 20 on the table top of the placement table 8 for convenient use.
[0059] In the embodiment 2, the first disc 10 and the second disc 20 are respectively connected with the translation reset mechanism 4, and meanwhile, a placement groove for the to-be-detected centering retainer can be arranged on the placement table 8, the placement groove is adapted to the size of the small end face or the large end face of the centering retainer, when detection, the first disc 10 and the second disc 20 are located on the inner side of the centering retainer and respectively abut against the pressure slope surfaces 70 of the opposite window hole window beams, and the centering retainer can be placed in the placement groove to achieve the consistency of different placement positions of the centering retainers, but the first disc 10 and the second disc 20 need to be close to each other to enable the centering retainer to be placed in the placement groove.
[0060] Considering that the pressure slope surfaces 70 of the retainer can also be asymmetric, there can be a situation that the first disc 10 or the second disc 20 only abuts against the pressure slope surface 70 of one side of the window hole window beam and does not contact the pressure slope surface 70 of the other side, and the pressure slope depth is qualified, therefore, in the embodiment, the second disc 20 or the first disc 10 which is relatively fixed can rotate and is connected with the rotation reset mechanism 5, and the rotation of the second disc 20 or the first disc 10 can be detected by the rotation measuring piece 6 to determine the symmetry of the adjacent window beam pressure slope surfaces 70.
[0061] Specifically, the window hole of the to-be-detected centering retainer is close to the pressure slope surface 70 abutting against the fixed second disc 20, when the pressure slope surfaces 70 on both sides of the window hole are relatively symmetrical, the second disc 20 does not rotate, when the pressure slope surfaces 70 on both sides of the window hole are asymmetric, the second disc 20 rotates due to the asymmetric positions of the pressure slope surfaces 70 on both sides contacting the second disc 20, and the rotation is detected by the rotation measuring piece 6, thereby quickly screening out unqualified products.
[0062] The specific implementation of the rotation reset mechanism 5 is as follows Figure 5, the rotating reset mechanism 5 includes a column 50 and a torsion spring 51, the second disc 20 is rotationally connected to the column 50, one end of the torsion spring 51 is connected to one end of the column 50 and connected to the second disc 20, the second disc 20 is installed on the column 50 through a bearing 52, the column 50 is provided with a protrusion, the bearing 52 is provided with a clamping groove, the clamping groove is connected with the protrusion, so that the second disc 20 can rotate on the column 50, and the torsion spring 51 can make the second disc 20 return to the initial position after the measurement is completed, so that the next detection work of the self-aligning retainer can be carried out, and the rotating measuring element 6 can select a laser ranging sensor, such as Figure 6 , the second disc 20 can be designed to have different thicknesses, and when it rotates, the laser ranging sensor can detect different height positions to determine the symmetry of the pressure slope surface 70, and the thickness of the first disc 10 can be adapted to the width of the pressure slope surface 70 to prevent the case that although the pressure slope surface 70 is symmetrical, the different height positions of the single pressure slope surface 70 exist in different depths, for example, the first disc 10 only contacts the deep surface and is judged to be qualified, but the actual shallow surface is not contacted, and the actual pressure slope surface 70 is unqualified, when the thickness of the first disc 10 is adapted to the pressure slope surface 70, the shallow surface is contacted first and the depth of the pressure slope surface 70 can be directly determined, so as to improve the detection accuracy.
[0063] As a preferred embodiment of the present application, the placement table 8 is arranged on the distance adjusting mechanism 9, and the distance adjusting mechanism 9 can adjust the initial positions of the first detection element 1 and the second detection element 2 to adapt to different sizes of retainers.
[0064] The specific embodiment of the distance adjusting mechanism 9 is as follows Figure 4 or 5, including a lead screw 90, a first nut seat 91, a support seat 92 and a hand wheel 93, the lead screw 90 is divided into two parts, and opposite threads are arranged on the lead screw 90, the first nut seat 91 and the second nut seat 13 are respectively located in different thread segments, and the first nut seat 91 and the second nut seat 13 can be close to or away from each other by rotating the hand wheel 93, so as to adjust the distance between the first disc 10 and the second disc 20, so as to adapt to different sizes of retainers.

If the number is less than the standard number and outside the reasonable error range, it indicates that the slope surface is shallow. If the number is greater than the standard number and outside the reasonable error range, it indicates that the slope surface is deep. If the number is within the error range of the standard number, it indicates that the slope surface meets the requirements and there is consistency.
