Description
Technical Field
[0001] The utility model belongs to the technical field of bearing retainer clamping equipment, and in particular relates to a loading and unloading clamping device for a tapered roller bearing retainer. Background Art
[0002] A bearing retainer is a bearing component that partially wraps around all or part of the rolling elements and moves with them to isolate the rolling elements and usually guide the rolling elements and retain them in the bearing.
[0003] During the processing of the retainer, the workpiece is usually taken out of the equipment bin by a clamping device and placed on the processing equipment (such as a punch press) for processing. Since there are many specifications and models of tapered bearing retainer workpieces with different outer diameters, a single clamping device is difficult to adapt to a wide variety of retainer structures. Utility Model Content

Distance measuring sensors are installed on both sides of the clamping cylinder to detect whether the clamping device can clamp the retainer, and can prevent the adjustment slide plate from accidentally colliding with the retainer.
[0005] The utility model is realized by the following technical solutions:

The clamping device includes a clamping cylinder, an adjusting slide, a clamping column, and a distance sensor. The clamping cylinder includes a cylinder body, a push rod, and a push plate installed on both sides of the cylinder body. The push plate is vertically arranged and fixed to the push rod.

The clamping column is fixed to the bottom of the adjusting slide. The middle of the clamping column is concave to form a clamping arc surface. The clamping arc surface abuts and cooperates with the inner side of the small-diameter annular frame to achieve clamping of the retainer. The distance sensor is installed to the side wall of the cylinder body through the sensor fixing plate. The distance sensor points to the holder. The distance sensor is connected with the mobile device signal to facilitate the detection of whether the clamping device has completed the clamping of the holder.
[0007] Furthermore, at least two push rods are provided on both sides of the cylinder body, and each push rod is fixedly connected to the push plate.

[0012] Furthermore, the bottom surface of the distance measuring sensor is flush with the bottom surface of the adjusting slide plate, which facilitates the calculation of the distance measuring sensor and prevents the distance measuring sensor and the adjusting slide plate from colliding with the retainer.
[0013] Furthermore, a mounting hole cooperating with a mobile device is provided on the top of the cylinder body to facilitate the installation of the entire clamping device.
[0014] Furthermore, two adjusting slides are provided, and the two adjusting slides are symmetrically distributed relative to the cylinder body, thereby improving the clamping stability of the clamping device on the retainer.

[0030] like Figures 1 to 5 The present invention shows a tapered roller bearing retainer loading and unloading clamping device, which is installed on a mobile device 1. The retainer 2 includes a small-diameter annular frame 21, a large-diameter annular frame 22, and a plurality of window beams 23 connecting the small-diameter annular frame 21 and the large-diameter annular frame 22. The clamping device includes a clamping cylinder 3, an adjusting slide 5, a clamping column 7, and a distance sensor 8. The clamping cylinder 3 includes a cylinder body 31, a push rod 32, and a push plate 33 installed on both sides of the cylinder body 31. The push plate 33 is vertically arranged and fixed to the push rod 32. An L-shaped fixing plate 4 is fixed below the push plate 33, and a strip hole 41 is opened on the L-shaped fixing plate 4. The adjusting slide 5 is horizontally arranged and installed on the bottom of the L-shaped fixing plate 4. Along the extension direction of the adjusting slide 5, a plurality of evenly distributed limiting holes 51 are opened on the adjusting slide 5. The adjusting bolt 6 passes through the strip hole 41 and the limiting hole 51, so as to adjust the relative position of the adjusting slide 5 and the L-shaped fixing plate 4. The clamping column 7 is fixed to the bottom of the adjusting slide plate 5, and the middle of the clamping column 7 is recessed to form a clamping arc surface 71, which abuts against the inner side of the small-diameter annular frame 21 to clamp the retainer 2. The distance sensor 8 is installed on the side wall of the cylinder body 31 through the sensor fixing plate 9, and the distance sensor 8 points to the retainer 2. The distance sensor 8 is connected to the mobile device 1 signal to facilitate the detection of whether the clamping device has completed the clamping of the retainer 2.
[0031] In one embodiment, the clamping device is first installed on the mobile device 1, and the mobile device 1 moves the entire clamping device to the area to be loaded. The mobile device 1 controls the entire clamping device to descend until the distance sensor 8 detects that the distance from the retainer 2 reaches the set value, at which time the clamping arc surface 71 of the clamping column 7 is at the same height position as the small-diameter annular frame 21. Then, the cylinder body 31 pushes the push plate 33 to move to both sides of the cylinder body 31 through the push rod 32, thereby driving the clamping column 7 to move toward the retainer 2 until the clamping arc surface 71 abuts against the retainer 2, thereby achieving the clamping operation of the retainer 2. Finally, the mobile device 1 drives the clamping device and the retainer 2 to move to the position to be processed, and the cylinder body 31 drives the push rod 32 to contract to release the clamping of the clamping column 7 on the retainer 2, thereby completing the clamping movement and loading of the retainer 2. It should be noted that the mobile device 1 is an existing device used to drive the movement of the entire clamping device, which will not be described in detail here.
[0032] In one embodiment, when the type of the tapered bearing retainer 2 needs to be changed, the relative position of the adjusting slide plate 5 to the L-shaped fixing plate 4 is adjusted according to the diameter of the small-diameter annular frame 21 of the retainer 2, and the adjusting bolt 6 is passed through the limiting hole 51 closest to the strip hole 41, and then the adjusting bolt 6 and the adjusting slide plate 5 are moved along the extending direction of the strip hole 41 to move the adjusting slide plate 5 to an appropriate clamping position. Thus, the clamping device can be adapted to the tapered bearing retainer 2 of this type.
[0033] Preferably, both sides of the cylinder body 31 have at least two push rods 32, and each push rod 32 is fixedly connected to the push plate 33. A plurality of push rods 32 are provided to increase the stability of the connection between the cylinder body 31 and the push plate 33 and improve the load-bearing capacity of the clamping device.
[0034] Preferably, at least two clamping columns 7 are installed at the bottom of each adjusting slide plate 5 to improve the stability of the clamping columns 7 when clamping the retainer 2. The clamping columns 7 are detachably connected to the adjusting slide plate 5, which is convenient for repairing and replacing the clamping columns 7.
[0035] In one embodiment, if Figures 1 to 5 As shown, two push rods 32 are provided on both sides of the cylinder body 31 , and two clamping columns 7 are installed at the bottom of each adjusting slide plate 5 .
[0036] Preferably, an elastic arc pad is mounted on the outer side of the clamping arc surface 71 to protect the clamping column 7 and the retainer 2.
[0037] Preferably, a strip sliding hole 91 is provided on the sensor fixing plate 9, and the extension direction of the strip sliding hole 91 is consistent with the extension direction of the sensor fixing plate 9. The ranging sensor 8 is inserted into the strip sliding hole 91 and can slide along the strip sliding hole 91 to adjust the position of the ranging sensor 8, thereby facilitating the alignment of the ranging sensor 8 to the retainer 2.
[0038] In one embodiment, when different types of tapered bearing retainers 2 are replaced, the position of the distance measuring sensor 8 needs to be adjusted accordingly. The distance measuring sensor 8 can be held and moved along the strip slide hole 91 to move the distance measuring sensor 8 to the top of the small diameter annular frame 21 of the retainer 2, so as to detect the distance of the small diameter annular frame 21 relative to the clamping device. When the distance detected by the distance measuring sensor 8 reaches the set value, a data signal is sent to the mobile device 1 to prevent the distance measuring sensor 8 from colliding with the annular frame. When the clamping device lifts the retainer 2, the distance measuring sensor 8 can also detect the distance from the retainer 2. When the detected distance is greater than the set distance, it is determined that the clamping device has failed to successfully clamp the retainer 2, and the clamping device needs to be recalibrated.
[0039] Preferably, two distance measuring sensors 8 are provided, and the two distance measuring sensors 8 are symmetrically distributed relative to the cylinder body 31 , so as to improve the accuracy of the measurement data of the distance measuring sensors 8 .
[0040] Preferably, the bottom surface of the distance measuring sensor 8 is flush with the bottom surface of the adjusting slide plate 5 , which facilitates the calculation of the distance measuring sensor 8 and prevents the distance measuring sensor 8 and the adjusting slide plate 5 from colliding with the retainer 2 .
[0041] Preferably, a mounting hole 311 cooperating with the moving device 1 is provided above the cylinder body 31 to facilitate the installation of the entire clamping device.
[0042] Preferably, two adjusting slide plates 5 are provided, and the two adjusting slide plates 5 are symmetrically distributed relative to the cylinder body 31 , so as to improve the clamping stability of the clamping device on the retainer 2 .
[0043] Preferably, a limiting protrusion 52 is protruded from the top of the adjusting slide plate 5 , and a limiting groove 42 cooperating with the limiting protrusion 52 is provided below the L-shaped fixing plate 4 , so as to facilitate adjustment of the position of the adjusting slide plate 5 relative to the L-shaped fixing plate 4 .
[0044] When the above-mentioned tapered roller bearing retainer loading and unloading clamping device is used, the position of the clamping column 7 is roughly adjusted by installing the adjusting slide plate 5 between the clamping column 7 and the L-shaped fixing plate 4, and the limiting hole 51 into which the adjusting bolt 6 is inserted is changed, and the position of the clamping column 7 is finely adjusted by changing the position of the adjusting bolt 6 relative to the strip hole 41, so that the clamping device can be adapted to various types of tapered roller bearing retainers 2. Distance measuring sensors 8 are installed on both sides of the clamping cylinder to detect whether the clamping device can clamp the retainer 2, and to prevent the adjusting slide plate 5 from accidentally colliding with the retainer 2.
[0045] 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.
