Description

Technical Field

[0001] The present application relates to the technical field of bearing processing, and in particular to a bearing retainer drilling device for bearing production and processing. Background Art

[0002] Bearings are an indispensable component in mechanical transmission systems. They can support the rotating shaft and reduce the friction between the shaft and the bearing seat. A standard bearing usually consists of three main parts: an inner ring, an outer ring and rolling elements. The inner ring fits tightly with the rotating shaft, and the outer ring is installed in the bearing seat. The rolling elements are located between the inner and outer rings. Common rolling element forms are balls and rollers. These components of the bearing work together to ensure smooth rotation of the shaft and transfer of loads.

[0003] Among these components of the bearing, the main function of the bearing cage is to maintain the proper spacing between the rolling elements, prevent the rolling elements from contacting and rubbing against each other, thereby reducing wear and heat generation. The cage also helps the rolling elements to evenly distribute the load and improve the bearing's load capacity and rotation accuracy.

[0004] Drilling holes in bearing cages is a key step in the bearing production process. The purpose of drilling holes is to form holes on the cages for installing rolling elements. During the drilling process, high-precision drilling equipment is required to ensure the accuracy and consistency of the holes. For example, a bearing cage drilling device for bearing production and processing with publication number CN111804955A relates to the technical field of bearing production and processing. The prior art base, first gear, cylindrical cam, slide rod, support seat, support rod, annular support plate, arc clamping plate, limit cylinder, hollow tube, turntable, mounting cover, square shaft, driven bevel gear, mounting plate, electric push rod, annular rotating plate, annular plate, hollow cylinder, push rod, first stepper motor, hollow rotating cylinder, gear ring, driving gear, driving bevel gear, drill bit, threaded rod, mounting frame, second stepper motor, incomplete gear, second gear, T-rod, slider, guide rod and truncated cone guide seat. The prior art can better drill multiple holes of the cage, avoiding drilling holes of the cage one by one, thus improving the drilling efficiency and drilling speed.

[0005] However, the above-mentioned prior art still has some defects when processing the bearing retainer:

[0006] 1. The above-mentioned prior art drives the driving gear to rotate through the driving shaft, so that the gear ring and the hollow rotating cylinder drive the annular plate to rotate, and the annular plate drives the square rotating shaft to rotate through the driving bevel gear and the driven bevel gear, and the square rotating shaft drives the threaded rod to rotate, and the threaded rod drives the drill bit to rotate and move toward the cage at the same time to realize the drilling of the cage. However, this drilling method can only realize drilling from the outside of the bearing cage to the center.

[0007] In practical applications, the processing of bearing retainers requires circumferential centering drilling or axial through drilling. However, axial through drilling requires the drill to be able to drill into the retainer from one side and out from the other side. The above-mentioned prior art has limitations in design and it is impossible to achieve axial through drilling of the bearing retainer.

[0008] 2. The above-mentioned prior art presses the T-rod through the push rod, so that the T-rod drives the truncated cone guide seat to move downward, and the truncated cone guide seat drives the arc-shaped clamping plate to move toward the retaining frame through the guide rod, thereby clamping the retaining frame, and the push rod presses the T-rod with a constant stroke. Under the same stroke, the distance that the arc-shaped clamping plate moves toward the retaining frame is constant, and the distance that the arc-shaped clamping plate extends determines the size of the clamped bearing retaining frame, that is, the arc-shaped clamping plate can only clamp bearing retaining frames of the same size, which has certain limitations, especially when clamping bearing retaining frames of different sizes.

[0009] Based on this, and in accordance with the above-mentioned viewpoints, there is still room for improvement in the existing technology for processing bearing retainers. Summary of the invention

DETAILED DESCRIPTION

[0047] The following is combined with Figures 1 to 11 This application is described in further detail.

[0048] An embodiment of the present application discloses a bearing retainer drilling device for bearing production and processing, which clamps the bearing retainer and then changes the drilling position to perform axial through drilling on the bearing retainer or perform circumferential centering drilling on the bearing retainer.

[0049] Example:

[0050] Reference Figure 1 and Figure 2 A bearing retainer drilling device for bearing production and processing includes a chassis 1, a plurality of columns 11 are arranged on the chassis 1, and a top plate 2 is commonly arranged at the upper ends of the plurality of columns 11.

[0051] When drilling a hole in the bearing retainer, first place the bearing retainer on the chassis 1, then start the driving member 9 provided on the top plate 2, the driving member 9 will drive the driving rod 3 slidingly penetrated on the top plate 2, so that the driving rod 3 moves downward, and drives the support plate 31 provided at the lower end of the driving rod 3 to move together, and a plurality of support rods 32 are slidingly penetrated on the support plate 31.

[0052] The support plate 31 drives the pressure plates 4 provided at the lower ends of the support rods 32 to move together through the support rods 32. At the same time, the pressure plate 4 moves downward through the sliding connection with the column 11, so that the lower end of the pressure plate 4 is pressed on the bearing retainer.

[0053] At the same time, the clamp 7 arranged between the support plate 31 and the pressure plate 4 will clamp the bearing retainer to ensure the stability of the bearing retainer during the drilling process. The buffer pads 41 arranged at the opposite ends of the pressure plate 4 and the chassis 1 can absorb pressure and provide buffering to protect the bearing retainer and the device itself.

[0054] After the lower end of the pressure plate 4 is pressed on the bearing retainer, the driving member 9 continues to drive the driving rod 3 to drive the support plate 31 to move downward, and compresses the clamping spring 69 arranged between the support plate 31 and the pressure plate 4, so that the clamping spring 69 provides elastic force and ensures that the pressure plate 4 presses the bearing retainer on the chassis 1, and the support plate 31 will drive the drill 5 arranged on the support plate 31 to approach the bearing retainer until the support plate 31 drives the drill 5 to move to the drilling position, at which time the driving member 9 stops driving the driving rod 3, and then starts the drill 5 to drill the bearing retainer.

[0055] The drill 5 can perform circumferential centering drilling or axial through drilling by changing the drilling direction. The drill 5 is also suitable for bearing retainers of various sizes and shapes and has good versatility and adaptability.

[0056] After the drilling is completed, the driving member 9 will start again to drive the driving rod 3 to move upward, and drive the support plate 31 to move together, gradually releasing the compressed clamping spring 69. After the support plate 31 drives the drill 5 set on the support plate 31 away from the bearing retainer, the support plate 31 will drive the pressure plate 4 away from the bearing retainer through the support rod 32. At the same time, the clamp 7 will release the bearing retainer that has completed the drilling, until the support plate 31 and the pressure plate 4 return to the initial position, and then the bearing retainer that has completed the drilling is removed from the chassis 1. At this point, the drilling of the bearing retainer is completed.

[0057] Reference Figure 2 and Figure 3 Specifically, the drill 5 includes a plurality of support grooves 51 uniformly opened on the pressure plate 4 in the circumferential direction, and the chassis 1 and the pressure plate 4 are both provided with a drilling groove 54 corresponding to one end of the L-shaped sliding frame 52.

[0058] When the driving member 9 drives the driving rod 3 to drive the support plate 31 to move downward, the support plate 31 will drive the L-shaped sliding frame 52 set in the support groove 51, and the vertical section of the L-shaped sliding frame 52 faces downward. After the lower end of the pressure plate 4 is pressed on the bearing retainer, the driving member 9 continues to drive the driving rod 3 to drive the support plate 31 to move downward. A guide hole 55 corresponding to one end of the L-shaped sliding frame 52 is opened on the pressure plate 4. The vertical section of the L-shaped sliding frame 52 will be inserted into the guide hole 55 until the support plate 31 drives the drill 5 to move to the drilling position. The drilling member 6 set in the L-shaped sliding frame 52 will move along the L-shaped sliding grooves 53 symmetrically opened on both sides of the L-shaped sliding frame 52, so that the drilling member 6 moves to align with the drilling position on the bearing retainer.

[0059] The drilling member 6 can change the drilling direction to perform circumferential center drilling or axial through drilling by moving along the L-shaped slide groove 53 in the L-shaped sliding frame 52; that is, the drilling member 6 can move in the L-shaped slide groove 53 of the L-shaped sliding frame 52 to move to the horizontal section of the L-shaped sliding frame 52 to perform axial through drilling, and the drilling member 6 can also move in the L-shaped slide groove 53 of the L-shaped sliding frame 52 to move to the vertical section of the L-shaped sliding frame 52 to perform circumferential center drilling.

[0060] At the same time, the horizontal section and the vertical section of the L-shaped sliding frame 52 both have a stroke. The drilling member 6 moves in the horizontal section of the L-shaped sliding frame 52 and can be moved to a suitable drilling position according to bearing retainers of different sizes. Similarly, the drilling member 6 moves to a suitable drilling position in the vertical section of the L-shaped sliding frame 52 according to the height of the bearing retainer, thereby being suitable for bearing retainers of various sizes and shapes.

[0061] Reference Figures 2 to 4 The drilling member 6 includes a sliding support block 61 slidably arranged in an L-shaped sliding frame 52 , and L-shaped racks 63 are symmetrically arranged on both sides of the L-shaped sliding frame 52 .

[0062] The existing motor driving technology is used to drive the roller 62 passing through one end of the sliding support block 61 to rotate, and the rotating roller 62 will drive the transmission gear 621 symmetrically arranged on both sides of the roller 62 to rotate together. The rotating transmission gear 621 will drive the sliding support block 61 to move in the L-shaped sliding frame 52 by engaging with the L-shaped rack 63; at the same time, the guide wheels 66 symmetrically arranged on both sides of the sliding support block 61 will rotate with the movement of the sliding support block 61, and the guide wheels 66 or the correspondence with the L-shaped slide groove 53 enable the sliding support block 61 to move smoothly in the L-shaped sliding frame 52.

[0063] The roller 62 drives the transmission gear 621 to mesh with the L-shaped rack 63, so that the sliding support block 61 moves in the L-shaped sliding frame 52, and the sliding support block 61 moves to the drilling position of the bearing retainer in the horizontal section of the L-shaped sliding frame 52.

[0064] A drilling shaft 64 is slidably penetrated on the sliding support block 61, and a drilling gear 67 threadedly connected to the drilling shaft 64 is rotatably provided on the sliding support block 61. Then, a driving motor 68 provided through a bracket on the sliding support block 61 is started, and the driving motor 68 drives a driving gear 681 provided on its driving end to rotate. The rotating driving gear 681 drives the drilling gear 67 to rotate by meshing with the drilling gear 67.

[0065] The rotating drilling gear 67 will drive the drilling shaft 64 to move downward through the threaded connection with the drilling shaft 64, and drive the detachable drill bit 65 set at the lower end of the drilling shaft 64. The drill bit 65 can rotate on the drilling shaft 64. The rotating drill bit 65 will move toward the bearing retainer driven by the drilling shaft 64 to axially drill the bearing retainer.

[0066] Similarly, the roller 62 drives the transmission gear 621 to engage with the L-shaped rack 63, so that the sliding support block 61 moves in the L-shaped sliding frame 52, and the sliding support block 61 moves to the drilling position of the bearing retainer in the vertical section of the L-shaped sliding frame 52. At this time, the sliding support block 61 will drive the drilling shaft 64 and the drill bit 65 to move into the drilling groove 54, and ensure that the sliding support block 61 moves to the area between the pressure plate 4 and the chassis 1. The width of the drilling groove 54 allows the drilling shaft 64 and the drill bit 65 to pass through, and the width of the guide hole 55 allows the sliding support block 61 to pass through.

[0067] Then, the driving motor 68 is started, and the driving motor 68 drives the driving gear 681 provided on the driving end thereof to rotate. The rotating driving gear 681 meshes with the drilling gear 67, thereby driving the drilling gear 67 to rotate.

[0068] The rotating drilling gear 67 will drive the drilling shaft 64 to move toward the center of the bearing retainer through the threaded connection with the drilling shaft 64, and drive the detachable drill bit 65 set at the lower end of the drilling shaft 64. The drill bit 65 can rotate on the drilling shaft 64. The rotating drill bit 65 will move toward the center of the bearing retainer driven by the drilling shaft 64 to perform circumferential centering drilling on the bearing retainer.

[0069] The drill bit 65 can be removed from the drilling shaft 64 to facilitate drilling operations or replacement of the drill bit 65 with a different size.

[0070] Reference Figures 5 to 7 Specifically, the clamp 7 includes a sliding rod 71 slidably inserted into the driving rod 3 , and one end of the sliding rod 71 slides through the pressure plate 4 , and a sliding hole 72 is opened on the sliding rod 71 .

[0071] When the driving rod 3 drives the supporting plate 31 to move downward, the driving rod 3 will drive the sliding rod 71 to move together, and the conical clamping block 73 slidingly arranged in the sliding hole 72 will be driven together. A plurality of conical inclined plates 74 are arranged on the conical clamping block 73. The inclined surfaces of the plurality of conical clamping blocks 73 form a tip 76 downward. The tip 76 slides through the sliding rod 71 until the tip 76 hits the clamping member 8 set on the chassis 1. The inclined surface of the conical inclined plate 74 hits the clamping member 8, so that the clamping member 8 clamps the bearing retainer by internal clamping.

[0072] Then, as the driving rod 3 drives the supporting plate 31 and the pressure plate 4 to continue to move downward, the driving rod 3 will drive the limiting plate 77 provided at its upper end and slidably connected to the sliding hole 72, so that the limiting plate 77 moves in the sliding hole 72 and compresses the clamping spring 78 provided between the conical clamping block 73 and the limiting plate 77, and the clamping spring 78 is located in the sliding hole 72. The elastic force of the clamping spring 78 ensures that the conical clamping block 73 always triggers the clamping part 8, so that the bearing retainer can be stably clamped.

[0073] Subsequently, the pressure plate 4 will be pressed on the bearing retainer, thereby further ensuring the stability of the bearing retainer, and the pressure plate 4 and the support plate 31 are both provided with sliding holes 75 corresponding to the conical inclined plates 74, and the sliding holes 75 allow the conical inclined plates 74 to pass through, thereby preventing the pressure plate 4 and the support plate 31 from being unable to press the bearing retainer due to the interference of the conical inclined plates 74.

[0074] After the drilling of the bearing retainer is completed, the driving rod 3 will drive the limit plate 77 to move upward and gradually release the compressed clamping spring 78 until the limit plate 77 moves to the top of the sliding rod 71. At this time, the sliding rod 71 will drive the conical block 73 to move upward, so that the clamping member 8 releases the clamping of the bearing retainer, and the pressure plate 4 will move away from the bearing retainer together.

[0075] Reference Figure 7 and Fig. 9 The clamping member 8 includes a clamping ring 81 coaxial with the chassis 1, the clamping ring 81 is provided with a slot 811 corresponding to the conical inclined plate 74, and a clamping block 82 corresponding to the conical inclined plate 74 is slidably penetrated on the clamping ring 81, and a plurality of clamping blocks 82 are provided with a protrusion 83 at the opposite ends.

[0076] When the driving rod 3 drives the supporting plate 31 to move downward, the driving rod 3 will drive the sliding rod 71 to move together, and the conical clamping block 73 will be driven together, and the tip 76 will be inserted into the clamping hole 821 commonly opened between the opposite ends of the plurality of clamping blocks 82, and the clamping hole 821 corresponds to the tip 76, and then the inclined surface of the conical inclined plate 74 will be inserted into the clamping groove 811 and abut the clamping block 82, so that the clamping block 82 moves outward from the clamping ring 81 and compresses the reset spring 84 arranged between the protrusion 83 and the clamping groove 811.

[0077] The plurality of pressing blocks 82 will synchronously move outwards of the clamping ring 81, and one end of the pressing block 82 will contact the inner side of the bearing retainer, pressing the bearing retainer to be coaxial with the clamping ring 81, thereby ensuring the accuracy of the drilling position on the bearing retainer.

[0078] After the drilling of the bearing retainer is completed, the sliding rod 71 will drive the conical block 73 to move upward, and the conical block 73 will withdraw from the slot 811, and the clamping block 82 will move up along the inclined surface of the conical inclined plate 74 under the push of the return spring 84 and shrink into the clamping ring 81, thereby breaking away from the interference with the bearing retainer to release the clamping of the bearing retainer.

[0079] Reference Fig. 9 and Fig.10 The chassis 1 and the pressure plate 4 are both provided with a sliding hole 85 located between two adjacent drilling grooves 54 , and a pressing plate 86 is slidably arranged in the sliding hole 85 .

[0080] When drilling a hole in the bearing retainer, first place the bearing retainer on the clamping plate 86 of the chassis 1, and put the bearing retainer on the clamping ring 81. When the pressure plate 4 moves downward, the pressure plate 4 will drive the clamping plate 86 set thereon to move together. The clamping plate 86 is provided with a clamping inclined surface 88 at one end facing between the chassis 1 and the pressure plate 4. The rotating shaft 89 rotatably arranged on the clamping inclined surface 88 will press the bearing retainer with the pressure plate 4, and compress the opposite ends of the chassis 1 and the pressure plate 4. The clamping spring 87 located on one side of the clamping plate 86 is arranged through the bracket. The clamping spring 87 will provide elastic force, so that the clamping plate 86 drives the rotating shaft 89 to clamp the bearing retainer, ensuring that the bearing retainer will not be displaced during the drilling process.

[0081] Reference Fig.11Specifically, the driving member 9 includes a driven gear 91 rotatably arranged on the top plate 2 and threadedly connected to the driving rod 3. A driving motor 92 is arranged on the top plate 2 through a bracket. The driving motor 92 drives a rotating gear 93 arranged at its driving end to rotate. The rotating transmission gear 621 drives the driven gear 91 to rotate by meshing with the driven gear 91, so that the driven gear 91 drives the driving rod 3 to move through the threaded connection.

[0082] The implementation principle of the present invention is:

[0083] (1): When drilling a hole in the bearing retainer, first place the bearing retainer on the abutment plate 86 of the chassis 1 and then sleeve the bearing retainer on the clamping ring 81.

[0084] (2): Then, the driving member 9 provided on the top plate 2 is started, and the driving member 9 drives the driving rod 3 slidingly provided on the top plate 2, so that the driving rod 3 moves downward and drives the supporting plate 31.

[0085] (3): When the driving rod 3 drives the supporting plate 31 to move downward, the driving rod 3 drives the sliding rod 71 to move together, and the conical block 73 slidably arranged in the sliding hole 72 will be driven together.

[0086] (4): The tip 76 of the conical clamping block 73 will be inserted into the clamping hole 821 commonly opened between the opposite ends of the plurality of clamping blocks 82, and then the inclined surface of the conical inclined plate 74 will be inserted into the clamping groove 811 and abut against the clamping block 82, so that the clamping block 82 moves outward from the clamping ring 81 and compresses the return spring 84 arranged between the protrusion 83 and the clamping groove 811.

[0087] (5): Multiple tightening blocks 82 will move synchronously to the outside of the clamping ring 81, and one end of the tightening block 82 will contact the inner side of the bearing retainer, tightening the bearing retainer to make it coaxial with the clamping ring 81, ensuring the accuracy of the drilling position on the bearing retainer.

[0088] (6): Then, as the driving rod 3 drives the support plate 31 and the pressure plate 4 to continue to move downward, the driving rod 3 will drive the limit plate 77 provided at its upper end and slidably connected to the sliding hole 72, so that the limit plate 77 moves in the sliding hole 72 and compresses the clamping spring 78 provided between the conical clamping block 73 and the limit plate 77 and located in the sliding hole 72. The elastic force of the clamping spring 78 ensures that the conical clamping block 73 always triggers the clamping member 8, so that the bearing retainer can be stably clamped.

[0089] (7): When the pressure plate 4 moves downward, the pressure plate 4 will drive the clamping plate 86 arranged thereon to move together. The clamping plate 86 is provided with a clamping inclined surface 88 at one end facing between the chassis 1 and the pressure plate 4. The rotating shaft 89 rotatably arranged on the clamping inclined surface 88 will press the bearing retainer along with the pressure plate 4 and compress the opposite ends of the chassis 1 and the pressure plate 4 through the clamping spring 87 arranged on one side of the clamping plate 86 by the bracket. The clamping spring 87 will provide elastic force so that the clamping plate 86 drives the rotating shaft 89 to press against the bearing retainer, thereby ensuring that the bearing retainer will not be displaced during the drilling process.

[0090] (8): After the lower end of the pressure plate 4 is pressed on the bearing retainer, the driving member 9 continues to drive the driving rod 3 to drive the support plate 31 to move downward, and the vertical section of the L-shaped sliding frame 52 will be inserted into the guide hole 55 opened on the pressure plate 4 and corresponding to one end of the L-shaped sliding frame 52, until the support plate 31 drives the drill 5 to move to the drilling position.

[0091] (9): The roller 62 drives the transmission gear 621 to mesh with the L-shaped rack 63, so that the sliding support block 61 moves in the L-shaped sliding frame 52. The sliding support block 61 moves to the drilling position of the bearing holder at the horizontal end of the L-shaped sliding frame 52. The rotating drilling gear 67 drives the drilling shaft 64 to move downward through the threaded connection with the drilling shaft 64, and drives the detachable drill bit 65 set at the lower end of the drilling shaft 64. The drill bit 65 can rotate on the drilling shaft 64. The rotating drill bit 65 will move toward the bearing holder under the drive of the drilling shaft 64 to perform axial through-drilling on the bearing holder.

[0092] (10): Alternatively, the roller 62 drives the transmission gear 621 to mesh with the L-shaped rack 63, so that the sliding support block 61 moves in the L-shaped sliding frame 52, and the sliding support block 61 moves to the drilling position of the bearing retainer in the vertical section of the L-shaped sliding frame 52. At this time, the sliding support block 61 will drive the drilling shaft 64 and the drill bit 65 to move between the pressure plate 4 and the chassis 1 through the drilling groove 54. The width of the drilling groove 54 allows the drilling shaft 64 and the drill bit 65 to pass through, and the width of the guide hole 55 allows the sliding support block 61 to move through.

[0093] (11): The rotating drilling gear 67 will drive the drilling shaft 64 to move toward the center of the bearing retainer through the threaded connection with the drilling shaft 64, and drive the detachable drill bit 65 set at the lower end of the drilling shaft 64. The drill bit 65 can rotate on the drilling shaft 64. The rotating drill bit 65 will move toward the center of the bearing retainer driven by the drilling shaft 64 to perform circumferential centering drilling on the bearing retainer.

Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
