Description

Technical Field

[0001] The invention belongs to the field of bearing retainer pocket processing, in particular to a segmented bearing retainer pocket processing device and method. Background Art

[0002] A cage (also known as a bearing retainer) refers to a bearing part that partially wraps all or part of the rolling elements and moves with them to isolate the rolling elements, and usually guides the rolling elements and keeps them in the bearing; a segmented bearing cage is composed of multiple independent cage units, which can be one-piece open rings, or composed of two or more segments; a bearing cage's "pocket" refers to a hole or groove on the cage used to accommodate rolling elements (such as balls or rollers).

[0003] A patent application with publication number CN111730106A discloses a rolling bearing cage pocket processing tooling and equipment, including a base, a supporting device, a cage, a spindle, a rotating device and a locking device, wherein: the supporting device is installed on the base; one end of the spindle is connected to the supporting device, and a rotating device is installed on its end face; the cage is fixedly sleeved on the other end of the spindle; the locking device fixes the spindle and the supporting device as one. The rolling bearing cage pocket processing tooling and equipment, in addition to the basic functions of a drilling machine, also realizes the function of cage pocket processing. Compared with traditional cage pocket processing machines, it not only has more functions, but also has lower equipment cost. The tooling structure can fix and rotate the cage to achieve precise adjustment of the pocket processing position.

[0004] During use, although the above-mentioned device can fix and lock the retaining frame in front of the pocket hole, it is more difficult to fix a larger bearing retaining frame. If a large clamping device is used, the retaining frame may be overstressed and deformed. Multiple small clamps are used for clamping. When clamping, multiple clamps need to be adjusted, which is time-consuming. The outer surfaces need to be machined and there is no suitable clamping position. The traditional processing method is side top fixing, which is cumbersome and unstable, affecting the processing quality and low production efficiency. If one transmission is used to drive multiple clamps for clamping, the wear degree of the clamps is different due to the different processing force directions of each workpiece, making it impossible to clamp stably. Further processing will cause jitter, resulting in low processing accuracy. Summary of the invention

[0020] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0021] Embodiment 1, as Figures 1 to 3 as well as Figure 8 As shown, a segmented bearing retainer pocket processing equipment described in an embodiment of the present invention includes a base 1, two support blocks 11 are fixedly installed on the top of the base 1, a rotating block 14 is rotatably installed on the side wall of the support block 11, and a first placement table 15 is rotatably installed on the end of the rotating block 14. A turning tool 12 is provided on the base 1, and the turning tool 12 can move horizontally with the midpoint of the central axis of the base 1 as the center of a circle, and a turning tool 13 is provided on the turning tool 12. A clamping device 2 is fixedly installed at the top center of the first placement table 15, and the clamping device 2 includes a second placement table 21 and a clamping locking member 26. A workpiece 16 is placed on the top of the second placement table 21, and a workpiece clamping opening 161 is provided on the workpiece 16. A clamping locking member 26 is provided inside the second placement table 21, and the clamping locking member 26 includes a locking protrusion 262, and the locking protrusion 262 rotates to engage with the workpiece clamping opening 161 for fixing the workpiece 16.

[0022] It should be noted that if Figures 9 and 10 As shown in the figure, the pocket holes of the conventional cage are roughed with a hollow drill, and then the pocket holes are bored once with a forming boring tool of the same shape and diameter as the pocket holes. However, this processing method has large cutting force, severe tool wear and low efficiency. Fig.11 As shown, a plunge milling cutter is used for roughing. Since the plunge milling cutter diameter is smaller than the minimum size of the pocket opening, step roughing can be performed according to the shape of the pocket. The machining efficiency is high, the tool wear is small, and the tool life is long. After roughing with the plunge milling cutter, the machining allowance left for fine boring is very small, and the fine boring tool is used to process to the finished product size. Since the fine boring machining amount is small, the machining efficiency is high, the tool wear is small, and the tool life is long, the overall machining efficiency is significantly improved.

[0023] The segmented retaining frame has a larger appearance, and when it is fixed, it is generally fixed by the side top. However, during the processing, if the workpiece 16 needs to be finely adjusted, the operation steps are relatively cumbersome, resulting in low production efficiency. Therefore, a clamping locking member 26 is provided inside the second placement table 21, and a locking protrusion 262 is provided on the top of the clamping locking member 26. When the workpiece 16 needs to be fixed, the clamping locking member 26 can be driven to rise and fall by a telescopic rod. After lifting and falling, the angle of the clamping locking member 26 is rotated, thereby driving the locking protrusion 262 to rotate. The locking protrusion 262 rotates to engage with the workpiece clamping port 161, thereby clamping the workpiece 16.

[0024] Embodiment 2, as Figures 1 to 4 As shown, a segmented bearing retainer pocket processing device described in an embodiment of the present invention includes a base 1, two support blocks 11 are fixedly installed on the top of the base 1, a rotating block 14 is rotatably installed on the side wall of the support block 11, and a first placement table 15 is rotatably installed on the end of the rotating block 14. A turning tool 12 is provided on the base 1, and the turning tool 12 can move horizontally with the midpoint of the central axis of the base 1 as the center of a circle. A turning tool 13 is provided on the turning tool 12, and a clamping device 2 is fixedly installed at the top center of the first placement table 15; the clamping device 2 includes a second placement table 21 and a lifting ring 22, and the second placement table 21 A workpiece 16 is placed on the top of the second placement table 21, and a plurality of adjusting members 25 are movably installed inside the second placement table 21. A plurality of rods are provided on the top of the lifting ring 22 and are connected to the bottom end of the adjusting member 25. The adjusting member 25 includes an adjusting column 251. A rotation limit member 27 is provided inside the second placement table 21. The output end of the rotation limit member 27 slides on the outer wall of the adjusting column 251 to limit the adjusting column 251. A clamping and locking member 26 is slidably installed inside the adjusting member 25. When the adjusting member 25 is lifted or lowered, it rotates inside the second placement table 21, driving the clamping and locking member 26 to clamp the workpiece 16.

[0025] It should be noted that the pockets of large segmented bearing cages need to be fine-machined afterwards, and the bearing cage (the full text refers to Figure 1 The workpiece 16 in the processing needs to be clamped and limited during the processing. If a larger clamp is used, a slight shake may occur when processing the workpiece clamping opening 161 provided on the workpiece 16, resulting in poor processing accuracy. If multiple clamps are used for clamping, the clamps will wear out over time. During the clamping process, the workpiece cannot be clamped uniformly after rotating a certain angle. If multiple operations are performed during clamping, it is time-consuming. In order to solve this problem, the following improvements have been made; First, the motor is used to drive the rotating block 14 to rotate, so that the rotating block 14 drives the first placement table 15 to be located at the bottom, and then the workpiece 16 is hoisted by the lifting device, so that the workpiece 16 is placed on the second placement table 21, and then the position of the workpiece 16 is adjusted so that the center of the workpiece 16 is aligned with the center of the second placement table 21. The second placement table 21 is provided with a plurality of grooves, so that the adjusting member 25 and the clamping and locking member 26 can slide inside the second placement table 21 and can be extended at the same time. When the adjusting member 25 and the clamping and locking member 26 are completely retracted to the inside of the second placement table 21, the top end of the clamping and locking member 26 is aligned with the top of the second placement table 21. The grooves are aligned, so that the top of the second placement platform 21 becomes a complete plane. After the center of the circle is aligned, the telescopic rod is started to drive the lifting ring 22 to rise. A plurality of rods are arranged on the lifting ring 22 and are connected to the bottom centers of a plurality of adjusting members 25, thereby driving the adjusting member 25 to rise. The adjusting column 251 on the adjusting member 25 is meshed with the rotation limit member 27, and the output end of the rotation limit member 27 is slidably connected with the outer wall of the adjusting column 251, so that the adjusting member 25 rotates during the rising process. The adjusting column 251 rotates 180° under the action of the rotation limit member 27, and the clamping locking member 26 is slidably installed inside the adjusting member 25, so that the adjusting member 25 can be adjusted. The clamping and locking member 26 is driven to rise and rotate 180 degrees, and the upper part of the clamping and locking member 26 clamps the top of the workpiece clamping opening 161 on the workpiece 16, and the interior of the clamping and locking member 26 is provided with a truncated cone nut 267 and a locking extrusion block 268, and the internal thread of the truncated cone nut 267 is installed with a threaded column 263, and the top of the threaded column 263 is fixedly installed with the clamping and locking block 261, so that when the clamping and locking block 261 clamps the workpiece clamping opening 161, it can adapt to different heights, facilitate the processing of the workpiece 16, and prevent the workpiece 16 from being clamped too much due to the difficulty in adjusting the elastic force of the spring when using the spring. The problem of being too tight or too loose is solved, and then the side top blank of the workpiece 16 is fixed, the end face of the workpiece 16 is roughly milled until it is flat, and a threaded blind hole is pre-machined on the workpiece 16; it is connected and fastened with screws to the clamping device 2; all contours on the workpiece 16 are fine-milled and clamped with multiple clamping and locking parts 26; the excess amount on the end face of the workpiece 16 (at the chuck) is milled off; the remaining contour on the workpiece 16 is fine-milled to the finished product, and the locking extrusion block 268 and the frustum nut 267 are squeezed against each other to have a locking function to prevent the workpiece 16 from vibrating during processing, and the connection between the support block 11, the rotating block 14 and the first placement table 15 allows the workpiece 16 to change the processing angle.

[0026] like Figure 3 to Figure 4As shown, the clamping device 2 includes a second placing table 21 fixedly installed at the top center of the first placing table 15, a lifting ring 22 is slidably installed inside the lower end of the second placing table 21, and a plurality of support columns 23 are fixedly installed on the top of the lifting ring 22, and the number of the support columns 23 corresponds to the slot on the workpiece 16, and a hydraulic rod 24 is fixedly installed on the bottom end of the lifting ring 22, and the bottom end of the hydraulic rod 24 is connected to the top of the first placing table 15, and an adjusting member 25 is fixedly installed on the top of the support column 23, and the outer wall of the adjusting member 25 is located inside the second placing table 21 and a rotating limit member 27 is provided, and the rotating limit member 27 is used to adjust the angle of the adjusting member 25 when the adjusting member 25 is raised or lowered, and a clamping locking member 26 is slidably installed inside the adjusting member 25, and the clamping locking member 26 is used to clamp the slot on the workpiece 16.

[0027] It should be noted that when the workpiece 16 needs to be clamped, the hydraulic rod 24 is started, and the hydraulic rod 24 rises to drive the lifting ring 22 and the support column 23 to rise, and the support column 23 rises to drive the adjusting member 25 and the clamping locking member 26 to rise. A number of support columns 23 are arranged on the top of the lifting ring 22. By lifting or lowering the lifting ring 22, the lifting effect of multiple adjusting members 25 and the clamping locking member 26 can be achieved, and the adjusting member 25 rotates under the action of the rotating limit member 27, thereby driving the clamping locking member 26 to rotate, thereby achieving the clamping effect of the workpiece clamping port 161, and the connection method of the second placement table 21 and the first placement table 15 can be set to a rotating connection and a fixed connection through a transmission, so as to facilitate the processing of the workpiece 16.

[0028] like Figure 3 As shown, a first slide groove 211 is provided inside the second placement platform 21, and a first limiting protrusion 221 is provided on the outer wall of the lifting ring 22. The first slide groove 211 is engaged with the first limiting protrusion 221, and the first slide groove 211 and the first limiting protrusion 221 limit the lifting ring 22 when it is raised or lowered.

[0029] It should be noted that since the lifting ring 22 slides on the lower inner wall of the second placement table 21, it may not be able to maintain uniform force during the rising process. Therefore, a first sliding groove 211 is provided on the inner wall of the second placement table 21, and a first limiting protrusion 221 is provided on the outer wall of the lifting ring 22, so that the lifting ring 22 can be lifted up at any angle of the bottom end of the lifting ring 22, and the rising angle of the lifting ring 22 will not be tilted.

[0030] like Figures 3 to 5As shown, the adjusting member 25 includes an adjusting column 251 fixedly mounted on the top of the supporting column 23, the outer wall of the adjusting column 251 is provided with an adjusting slot 252 and a limiting groove 253, the adjusting slot 252 and the limiting groove 253 are used to engage with the rotation limiting member 27, the upper end inner wall of the adjusting column 251 is provided with an inner wall limiting protrusion 254, the inner wall limiting protrusion 254 is used to drive the clamping locking member 26 to rotate when the adjusting column 251 rotates.

[0031] It should be noted that an inner wall limiting protrusion 254 is provided inside the adjusting member 25 for limiting the clamping locking member 26, and an adjusting groove 252 is provided on the lower outer wall of the adjusting member 25, so that when the rotating limiting member 27 is raised or lowered, the adjusting column 251 can be driven to rotate, and the setting of the limiting groove 253 ensures that there will be no jamming when the output end of the rotating limiting member 27 slides on the outer wall of the adjusting groove 252.

[0032] like Figures 5 and 6 As shown, the clamping locking member 26 includes a threaded column 263 slidably installed inside the upper end of the adjusting column 251, a clamping locking block 261 is fixedly installed on the top of the threaded column 263, a locking protrusion 262 is fixedly installed on the outer wall of the clamping locking block 261, a threaded groove 264 is provided on the threaded column 263, the threaded groove 264 is meshed with the inner wall limiting protrusion 254, and a conical nut 267 is threadedly installed on the outer wall of the threaded column 263, and the conical nut 267 is used to adapt to the grooves of different heights on the workpiece 16.

[0033] It should be noted that when the adjusting column 251 rotates, an inner wall limit protrusion 254 is provided at the upper end of the adjusting column 251, and the inner wall limit protrusion 254 engages with the threaded groove 264 on the outer wall of the threaded column 263, thereby driving the clamping locking member 26 to rotate during the process of rising, and the outer wall thread of the threaded column 263 is threaded with a conical nut 267. When the clamping locking block 261 and the locking protrusion 262 are worn during use, the height of the conical nut 267 on the outer wall of the threaded column 263 is adjusted so that the lifting ring 22 rises to the same height, and the workpiece clamping port 161 on the workpiece 16 can still be clamped firmly.

[0034] like Figure 5 As shown, a third spring 2671 is fixedly installed on the top of the truncated cone nut 267, and a locking extrusion block 268 is fixedly installed on the end of the third spring 2671. A locking groove 269 is provided inside the locking extrusion block 268.

[0035] It should be noted that the height to which the adjusting column 251 rises is the same as the height to which it falls, so a third spring 2671 is provided at the top of the truncated cone nut 267, and a locking extrusion block 268 is provided at the top of the third spring 2671. When the threaded column 263 drives the truncated cone nut 267 and the third spring 2671 to rise, the locking extrusion block 268 is simultaneously driven to rise, and the outer diameter of the locking extrusion block 268 is smaller than the outer diameter of the top of the adjusting column 251. Therefore, when the locking extrusion block 268 rises to the top of the inner wall of the adjusting column 251, it no longer rises, and the threaded column 263 The cone nut 267 is driven to rise continuously, so the third spring 2671 is compressed, so that the top end of the cone nut 267 is squeezed toward the inside of the locking extrusion block 268, and the locking extrusion block 268 is provided with a locking groove 269, so as to keep the locking extrusion block 268 to produce a certain deformation. At the same time, the mutual squeezing of the cone nut 267 and the locking extrusion block 268 makes the adjusting column 251 and the threaded column 263 not produce the problem of rising and falling due to the shaking of the workpiece 16 when clamping, thereby stabilizing the workpiece 16 and improving the processing accuracy.

[0036] like Figure 5 As shown, a first telescopic rod 266 is fixedly mounted on the bottom end of the truncated cone nut 267 , a bottom transmission ring 265 is fixedly mounted on the end of the first telescopic rod 266 , and the bottom transmission ring 265 is rotatably mounted at the bottom center of the inner wall of the adjusting column 251 .

[0037] It should be noted that the bottom transmission ring 265 is rotatably installed at the bottom end of the inner wall of the adjusting column 251. When it is necessary to adjust the position of the conical nut 267 on the outer wall of the threaded column 263, the bottom transmission ring 265 can be driven by a motor to rotate. The rotation of the bottom transmission ring 265 drives the first telescopic rod 266 to rotate about the center of the bottom transmission ring 265, thereby driving the conical nut 267 to rotate, thereby achieving the problem of adjusting the height of the conical nut 267 on the outer wall of the threaded column 263.

[0038] like Figure 7 As shown, the rotation limiter 27 includes a second telescopic rod 271 fixedly mounted inside the second placement platform 21, a second spring 272 is provided on the second telescopic rod 271, a hemispherical limit block 273 is fixedly mounted on the end of the second telescopic rod 271, and the hemispherical limit block 273 is slidably mounted on the adjusting slot 252 and the limit groove 253.

[0039] It should be noted that the hemispherical limit block 273 is hemispherical and slides inside the adjusting slot 252 and the limit groove 253. Therefore, when the adjusting column 251 rises, the hemispherical limit block 273 causes the adjusting column 251 to rotate when rising, and the side wall of the hemispherical limit block 273 is provided with a second spring 272 and a second telescopic rod 271, so that when sliding to the contact position of the limit groove 253 and the adjusting slot 252, the hemispherical limit block 273 can automatically adjust the extended length, thereby limiting the adjusting column 251.

[0040] like Figures 5 and 6 As shown, the outer diameter of the locking extrusion block 268 is smaller than the upper inner diameter of the adjusting column 251 , and the outer diameter of the bottom end of the truncated cone nut 267 is larger than the outer diameter of the locking extrusion block 268 .

[0041] It should be noted that the outer diameter of the locking extrusion block 268 is smaller than the upper inner diameter of the adjusting column 251, so that when the locking extrusion block 268 moves to the top of the inner wall of the adjusting column 251, it no longer follows the threaded column 263 to rise, and the outer diameter of the bottom end of the conical nut 267 is larger than the outer diameter of the locking extrusion block 268, so that when the conical nut 267 follows the threaded column 263 to rise, it can produce extrusion with the locking extrusion block 268 to achieve a limiting effect.

[0042] A segmented bearing cage pocket processing technology, the method adopts the segmented bearing cage pocket processing equipment, and comprises the following steps: Step 1: adjust the rotating block 14 so that the first placement table 15 is located at the bottom, use a sling to sling the workpiece 16 to the top of the first placement table 15, and adjust the position of the workpiece 16 so that the workpiece 16 is located at the top center of the second placement table 21; Step 2, use the telescopic rod to drive the multiple adjusting members 25 to rise. During the rising process of the adjusting members 25, the output end of the rotating limit member 27 slides on the outer wall of the adjusting member 25. When the adjusting member 25 rises, the direction of the clamping and locking member 26 is adjusted. When the adjusting member 25 rises to the top, the direction of the clamping and locking member 26 is rotated 180°. Then, use the telescopic rod to drive the multiple adjusting members 25 to fall. When the adjusting member 25 falls, the clamping and locking member 26 is driven to fall until the adjusting member 25 falls to the bottom, clamps the groove on the workpiece 16, completes the clamping and stabilizing work, and prevents the workpiece 16 from shaking during processing; Step 3: Then, the turning tool 12 is started to move and lift, and the output end of the turning tool 13 is started to rotate to process and grind the groove on the workpiece 16; Step 4: After the processing work is completed, start the telescopic rod again to drive the adjusting member 25 to rise. Under the action of the output end of the rotation limit member 27, the adjusting member 25 is driven to rotate, thereby adjusting the position of the clamping and locking member 26. When the adjusting member 25 rises to the top, the clamping and locking member 26 rotates 180°, and the clamping and locking member 26 restores its original angle. Then, start the telescopic rod to drive the adjusting member 25 to descend, and the clamping and locking member 26 can be driven to return to the inside of the groove on the second placement table 21.

[0043] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are within the protection of the present embodiment.
