DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in an exemplary manner in conjunction with the accompanying drawings.

[0027] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0028] In addition, in the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0029] In the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. However, if it is indicated as a direct connection, it means that the two connected bodies are not connected through an intermediate structure, but are only connected to form a whole through a connecting structure. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0030] In the present invention, unless otherwise clearly specified and limited, the first feature "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present invention. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0031] In the present invention, Figure 1-8 As shown, a bearing retainer detection device is provided, which is used to detect a bearing retainer 21, comprising: a workbench 1; a drive ring 3, rotatably placed on the upper side of the workbench 1; a plurality of roller sliding assemblies, which are arranged at intervals along the circumferential direction of the drive ring 3, the roller sliding assemblies are connected to the workbench 1 in a radial sliding manner along the drive ring 3, and a roller is provided at one end of the roller sliding assembly facing the center of the drive ring 3, the bearing retainer 21 can be placed between the rollers, and the bearing retainer 21 can cooperate with the rollers; a calibration member 2, comprising an annular calibration ring 201, when the roller is installed in cooperation with the bearing retainer 21, the calibration ring 201 can simultaneously abut against the inner edge of each roller and / or can simultaneously abut against the outer edge of each roller; wherein the drive ring 3 and each roller sliding assembly are respectively slidably connected so that when the drive ring 3 rotates, each roller sliding assembly moves respectively in the radial direction of the drive ring 3.

[0032] When the detection device of the present invention is used, the bearing retainer 21 to be detected is placed on the workbench 1, on the inner side of the drive ring 3, and then the drive ring 3 is rotated so that the roller sliding assembly slides radially inward relative to the drive ring 3, thereby causing each roller to move inward, and each roller simultaneously enters the pocket of the bearing retainer 21. After the roller enters the pocket, when the roller cannot move further inward, the calibration member 2 is coaxial with the bearing retainer 21, and then the calibration ring 201 is gradually moved toward the bearing retainer 21. If the pocket of the bearing retainer 21 is processed in a standard manner, the roller can form a standard fit with the bearing retainer, and each roller can simultaneously enter each pocket of the bearing retainer, and the calibration ring 201 just fits and abuts against the inner edge and / or outer edge of each roller. If the pocket of the bearing retainer 21 is not processed in a standard manner, the fit between the roller and the bearing retainer is not standard, and the calibration ring 201 interferes with the edge of the roller or has a gap.

[0033] When testing, the detection device of the present invention only needs to place the bearing retainer 21 on the workbench 1, and then rotate the drive ring 3 and move the calibration ring 201. There is no need to use measuring instruments or measuring tools. The operation is simple and easy to use, and the physical strength, energy and technical requirements of the detection personnel are relatively low.

[0034] Moreover, in the present invention, the driving ring 3 can be rotated to drive each roller sliding assembly to move linearly at the same time, and each pocket on each bearing retainer 21 can be detected at the same time, with high detection efficiency.

[0035] It is worth mentioning that, during the detection, the present invention adopts a method of directly installing the roller into the pocket and detecting the roller component, which can directly detect whether the roller can be installed according to the standard. Compared with the method of directly detecting the bearing retainer 21, the detection result obtained by the detection device of the present invention is closer to the actual use scenario.

[0036] It should be noted that, in this embodiment, the calibration piece 2 includes two calibration rings 201. During the inspection, the two calibration rings 201 simultaneously inspect the inner edge and the outer edge of the roller. When the pocket processing of the bearing retainer does not meet the standard, the roller deviates from the standard position and the calibration piece cannot be inserted.

[0037] In a preferred embodiment, Figure 4 , Figure 5As shown, the roller sliding assembly includes: a slider 4, which is slidably connected to the workbench 1 and has a fixing structure 5 for fixing the roller at one end facing the axis of the drive ring 3; a push rod 6, which is slidably connected to the drive ring 3 and includes a push rod body 601, a limiting portion 602, and an abutting portion 603 that movably passes through the slider 4, the limiting portion 602 is located at the inner end of the push rod body 601 and abuts against the slider 4, and the abutting portion 603 is located on the push rod body 601 on the outside of the slider 4; a spring a7, both ends of which abut against the abutting portion 603 and the slider 4 respectively.

[0038] Therefore, in actual use, when the drive ring 3 rotates, the drive ring 3 applies a radial thrust to the push rod 6. Since a spring a7 is provided between the abutment portion 603 and the slider 4, the slider 4 moves inward under the push of the spring a7. After the roller is installed in the pocket, the drive ring 3 can continue to rotate slightly, so that the spring a7 is compressed, so that the roller bearing retainer 21 has a certain extrusion force, thereby ensuring that the roller can fit the frame of the pocket, preventing the roller and the bearing retainer 21 from virtual contact, which is conducive to ensuring the accuracy of the detection. In addition, by providing the spring a7, it is also possible to prevent the excessive rotation force of the drive ring 3, which causes the roller to squeeze the bearing retainer 21, and prevent the bearing retainer 21 from being deformed or damaged.

[0039] When the driving ring 3 is rotated to move the push rod 6 outward, the slider 4 is driven to move outward through the limiting portion 602 .

[0040] In this embodiment, the spring a7 is sleeved on the outside of the push rod body 601. In an alternative embodiment, the spring a7 can also be arranged in parallel with the push rod body 601.

[0041] In this embodiment, the sliding connection between the slider 4 and the workbench 1 is as follows: Figure 5 As shown, an I-shaped slide rail is provided on the workbench 1, and the lower end of the slider 4 slides on the I-shaped slide rail. Of course, in actual use, the sliding connection structure between the slider 4 and the workbench 1 can also adopt other forms, such as providing a slide groove 12 on the workbench 1, and the slider 4 is slidably arranged in the slide groove 12.

[0042] In this embodiment, if Figure 5 As shown, the abutment portion 603 is configured as a tubular structure sleeved on the push rod body 601, and the abutment portion 603 is also provided with a component slidably connected to the drive ring 3, thereby facilitating the separate processing of the push rod body 601 and the abutment portion 603, and facilitating the processing of the entire push rod 6.

[0043] A further optimization is that the detection device also includes a handle 22 and a locking block 8 arranged on the top of the workbench 1, the handle 22 is rotatably connected to the drive ring 3, and the rotation axis of the handle 22 is perpendicular to the rotation axis of the drive ring 3; a locking groove 9 for accommodating the handle 22 is provided on the top of the locking block 8; when the drive ring 3 rotates until the roller abuts against the bearing retainer 21, the handle 22 can be in the locking groove 9, and the side wall of the locking groove 9 limits the handle 22 from driving the drive ring 3 to rotate.

[0044] Therefore, when the driving ring 3 is rotated, the driving ring 3 can be driven to rotate by rotating the handle 22, which is convenient for operation. Moreover, when the roller abuts against the bearing retainer 21, the position of the driving ring 3 can be maintained by placing the handle 22 in the locking groove 9, ensuring the abutment state between the roller and the bearing retainer 21. Then, the user can perform calibration testing through the calibration member 2. Therefore, the testing work can be completed by only one person, and the abutment force of the roller on the bearing retainer 21 can be ensured by fixing the handle 22 in the locking groove 9.

[0045] A further optimization is that the roller sliding assembly further includes: a connecting plate 10, which is arranged on the outside of the push rod body 601, and the connecting plate 10 is provided with a through hole for the push rod body 601 to move through; and a plurality of guide rods 11, which are arranged along the sliding direction of the slider 4, and the two ends of the guide rods 11 are respectively connected to the slider 4 and the connecting plate 10. By providing the connecting plate 10 and the guide rods 11, and the push rod body 601 slides through the connecting plate 10, the two ends of the push rod body 601 can be limited and fixed, and when the driving ring 3 rotates, the torque on the push rod body 601 can be reduced, so as to prevent the push rod body 601 from being deformed and damaged, and prevent the push rod body 601 from being deformed and damaged at the connection between the push rod body 601 and the slider 4, thereby increasing the stability of the entire device.

[0046] More specifically, in this embodiment, the sliding connection between the roller sliding assembly and the drive ring 3 is achieved as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a slide groove 12 is provided on the driving ring 3, and the slide groove 12 extends obliquely inward along the circumferential direction of the driving ring 3. The roller sliding assembly includes: a push rod 6; a connecting shaft 13, which is connected to the push rod 6; and a bearing 14, which is sleeved on the connecting shaft 13 and slidably arranged in the slide groove 12.

[0047] Therefore, when the driving ring 3 rotates, the bearing 14 rolls in the slide groove 12 relative to the radial movement of the driving ring 3, and then the entire roller sliding assembly can be driven to move in the radial direction of the driving ring 3. The present invention can facilitate processing by providing the slide groove 12 on the driving ring 3. At the same time, by arranging the bearing 14 on the connecting shaft 13, the bearing 14 can rotate so that when the driving ring 3 rotates, the bearing 14 performs a nearly rolling motion in the slide groove 12, thereby making the conversion between the circular motion of the driving ring 3 and the linear motion of the push rod body 601 smoother.

[0048] In this embodiment, the connecting shaft 13 is integrally disposed on the abutting portion 603 , and in some embodiments, the connecting shaft 13 may also be directly disposed on the push rod body 601 .

[0049] Of course, the structure of the sliding connection between the roller sliding assembly and the drive ring 3 is not limited to this, and may also have other forms. For example, a slider 4 sliding in the slide groove 12 is directly set on the connecting shaft 13; or, an arc-shaped slide rail is set on the drive ring 3, and an arc-shaped slide groove 12 is set on the push rod body 601.

[0050] It is worth mentioning that, in the present embodiment, there are two drive rings 3, the two drive rings 3 are arranged at intervals, and the push rod 6 is arranged between the two drive rings 3, the roller drive assembly includes two connecting shafts 13, and a bearing 14 is respectively provided on the two connecting shafts 13, the two connecting shafts 13 are respectively located on the upper and lower sides of the push rod 6, and the two bearings 14 are respectively slidably arranged in the slide grooves 12 at corresponding positions.

[0051] Thus, the entire push rod body 601 can be subjected to the driving force of the driving ring 3 at the same time on both the upper and lower sides, so that the force on the push rod body 601 is more uniform, and the push rod body 601 is prevented from being deformed. Figure 1 , Figure 4 As shown, the two drive rings 3 are connected by a connecting column, which can also increase the anti-deformation ability of the drive ring 3. In addition, by arranging the push rod body 601 between the two drive rings 3, the movement of the drive ring 3 in the vertical direction can be limited to a certain extent.

[0052] To be more specific, the end of the roller sliding assembly facing the center of the driving ring 3 is provided with a fixing structure 5 for fixing the roller, the fixing structure 5 includes a support plate, two fixing blocks 501 oppositely arranged on the top of the support plate, the inner wall of the opposite side of the fixing block 501 is arc-shaped, the roller is placed between the two fixing blocks 501, and is in contact with the inner wall of the two fixing blocks 501, and in the radial direction of the driving ring 3, the roller partially extends out of the inner end surface of the slider 4 and the inner end surface of the support plate. In this embodiment, as shown in the figure, a portion of the slider 4 constitutes the support plate.

[0053] Regarding the rotation connection between the driving ring 3 and the workbench 1, in this embodiment, as shown in FIG. Figure 4 , Figure 5 , Figure 7 As shown, the detection device also includes a plurality of rotating columns 15, each of which is arranged at intervals along the circumferential direction of the driving ring 3, and the rotating column 15 includes: a rotating column body 1501, which is connected to the workbench 1; a rotating fixing member, which is rotatably arranged on the outside of the rotating column body 1501, including a supporting portion 1502 for supporting the driving ring 3, and a side abutting portion 1503 for abutting against the side wall of the driving ring 3.

[0054] Thus, the drive ring 3 can be placed on the supporting portion 1502, and the movement of the drive ring 3 can be limited in the horizontal direction by the side abutment portion 1503, thereby facilitating the installation of the drive ring 3. Moreover, since the contact area between the drive ring 3 and the side abutment portion 1503 is small, the rotation resistance of the drive ring 3 can be reduced.

[0055] In the present embodiment, the rotating column 15 is disposed at the outer edge of the driving ring 3 . In an alternative embodiment, the rotating column 15 may also be disposed at the inner edge of the driving ring 3 .

[0056] A further optimization is that the supporting portion 1502 and the side abutment portion 1503 are connected to form a rotation fixing member, and the rotation fixing member is rotationally connected to the rotation column body 1501. Therefore, when the driving ring 3 rotates, the rotation fixing member can also rotate at the same time, which can further reduce the rotation resistance of the driving ring 3.

[0057] In this embodiment, if Figure 7 As shown, the rotating column 15 includes a base block connected to the workbench 1, a column installed on the base block, and an expanded diameter section at the bottom of the column. During installation, it is first sleeved on the column through a mounting ring to abut against the expanded diameter section, and then a fixing piece is sleeved on the outside of the mounting ring, and then a separator tube is sleeved on the outside of the column, a mounting ring is sleeved on the column on the upper side of the separator tube, and then a fixing piece is sleeved on the outside of the mounting ring.

[0058] A further optimization is that the detection device also includes: a support frame 16, which is arranged on the upper side of the workbench 1; a traction rope 18, one end of which is connected to the calibration piece 2, and the other end of which passes around the support frame 16; a counterweight block 17, which is connected to one end of the traction rope 18 passing around the support frame 16, and the weight of the counterweight block 17 is greater than the weight of the calibration piece.

[0059] In this embodiment, as shown in the figure, two pulleys are further provided on the support frame 16, thereby the traction rope 18 is also driven to move more smoothly.

[0060] Therefore, when in use, under normal conditions, the calibration piece 2 is lifted up under the action of the counterweight 17. When calibrating, the calibration piece 2 can be pulled down for use, which is more convenient to use. After use, the calibration piece 2 can also automatically return to its original position under the action of the counterweight 17, omitting the step of preventing the calibration piece 2 from falling.

[0061] A further optimization is that the calibration piece further comprises: a guide rail 19 connected to the calibration ring 201 and slidingly passing through the support frame 16; and a spring b20 disposed between the calibration ring 201 and the support frame 16. The guide rail 19 can prevent the calibration piece 2 from shaking at will, and the spring b20 can play a buffering role, so that when the calibration piece 2 returns to its original position, the calibration piece 2 can be prevented from violently impacting the support frame 16 due to excessive speed.

[0062] In this embodiment, two guide rails 19 are provided, thereby preventing the calibration member 2 from moving randomly.

[0063] Each embodiment in this specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other, and each embodiment focuses on the differences from other embodiments. In particular, for the system embodiment, since it is basically similar to the method embodiment, the description is relatively simple, and the relevant parts can be referred to the partial description of the method embodiment.

[0064] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
