Description

Technical Field

[0001] The present invention relates to the field of bearing retainer release, and more particularly to a bearing retainer blanking mechanism and a bearing assembly line. Background Art

[0002] The main function of a bearing retainer is to isolate the rolling elements, ensure their uniform distribution, reduce friction and wear, and improve the bearing's service life and performance. Assembly requires processes such as aligning the inner and outer rings, adding balls, placing the retainer, and pressing the retainer together. Retainer placement is usually done manually, but there are also mechanical methods for releasing the retainer. However, this has the following disadvantages: For example, the document with application number CN201520513127.3, entitled A Bearing Retainer Cutting-Out Device, drives the "blocking slider and blanking slider" to move simultaneously through a "waist-shaped groove". If they move simultaneously, when the blocking slider leaves the retainer, the blanking slider has not yet abutted against the blanking slider in time, resulting in a gap in the support of the retainer, and the retainer will fall off uncontrollably. Therefore, it is necessary to design a retainer blanking mechanism that can control the movement of the slider. Summary of the Invention

[0003] In view of the above defects, the present invention provides a bearing retainer blanking mechanism and a bearing assembly line to solve the above problems.

By setting the straight part and the arc part, the order of movement of the supporting block and the clamping block can be controlled.

DETAILED DESCRIPTION

[0018] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0019] This application provides a bearing cage blanking mechanism and a bearing assembly line, please refer to Figures 1-13 : including workbench 1; A storage rod 2 for storing the retainer; The support assembly 3 is fixedly connected to the workbench 1, the storage rod 2 is placed vertically, and the upper end of the storage rod 2 is detachably connected to the support assembly 3; A supporting block 4 can support the retainer; A clamping block 5, capable of clamping the retainer; The linkage component 6 can drive the supporting block 4 and the clamping block 5 to move back and forth alternately, and the moving directions of the supporting block 4 and the clamping block 5 point to the center of the retainer.

[0020] Specifically in actual application, before releasing the retainer, the retainer is manually placed on the storage rod 2, the storage rod 2 passes through the retainer, and then the storage rod 2 is placed on the support assembly 3. When the support block 4 is stationary, it plays a role in limiting the retainer from falling. At this time, the support block 4 supports the retainer of the lowest layer, hereinafter referred to as the first layer retainer; the external power source can drive the linkage component 6 to rotate. When the linkage component 6 rotates, it can first drive the clamping block 5 to move to a position close to the retainer until it clamps the retainer on the upper layer, hereinafter referred to as the second layer retainer. At this time, the second layer retainer can remain stationary by relying on the clamping force of the clamping block 5. As the linkage component 6 continues to rotate, the support block 4 moves in the direction away from the center of the retainer until the support block 4 releases the retainer; Afterwards, the external power source drives in the reverse direction, causing the linkage component 6 to reverse, driving the supporting block 4 to move toward the retainer, and the clamping block 5 to move away from the retainer. The clamping block 5 releases the second-layer retainer, and the second-layer retainer falls to the position of the original first-layer retainer; repeating the above actions can achieve the purpose of releasing the retainers one by one.

[0021] Reference Figure 1 、 Figure 2 、 Figure 3 、 Figure 11 and Figure 12 , and also includes a telescopic rod 31 installed on the support component 3. The telescopic end of the telescopic rod 31 is hinged to the linkage component 6. A circular hole 32 for the retainer to pass through is opened on the support component 3. A supporting platform 33 is provided near the lower end of the end face of the supporting block 4 for supporting the retainer. A rectangular protrusion 34 is installed near the center of the end face of the clamping block 5 for clamping the retainer.

[0022] Specifically in actual application, one end of the telescopic rod 31 is installed on the supporting assembly 3. The extension and retraction of the telescopic rod 31 can drive the linkage component 6 to rotate back and forth, thereby achieving the purpose of reciprocating movement of the supporting block 4 and the clamping block 5. The circular hole 32 through which the retainer passes moves downward, and the height of the contact position between the supporting platform 33 and the retainer is lower than the height of the contact position between the rectangular protrusion 34 and the retainer. This height difference is consistent with the distance between the retainers. The inner wall of the circular hole 32 can also keep the retainers in a stacked state, and the storage rod 2 extends into the circular hole 32.

[0023] The first embodiment of the linkage component 6, referring to Figure 1-Figure 7 The linkage component 6 includes a fixed ring 61 fixedly mounted on the support assembly 3, an annular protrusion 62 is provided at the lower end of the fixed ring 61, a rotating ring 63 is provided on the side wall of the annular protrusion 62, the rotating ring 63 and the annular protrusion 62 can rotate relative to each other, and a circular ring 64 is fixedly mounted on the lower surface of the annular protrusion 62, and the rotating ring 63 can be rotatably clamped between the fixed ring 61 and the circular ring 64; A rectangular groove 1 65 and a rectangular groove 2 66 are formed on the circular ring 64. The extending directions of the rectangular groove 1 65 and the rectangular groove 2 66 point to the center of the circular ring 64. There are multiple pairs of rectangular grooves 1 65 and rectangular grooves 2 66. The supporting block 4 is located in the rectangular groove 1 65, and the clamping block 5 is located in the rectangular groove 2 66. A driving groove 1 67 corresponding to the supporting block 4 is formed on the rotating ring 63, and a driving groove 2 68 corresponding to the clamping block 5 is formed on the rotating ring 63. A pin 69 is installed on each of the supporting block 4 and the clamping block 5. The pin 69 is inserted into the corresponding driving groove 1 67 and driving groove 2 68 respectively. One end of the driving groove 1 67 and the driving groove 2 68 is close to the center of the circular ring 64, and the other end is away from the center of the circular ring 64. The driving groove 1 67 and the driving groove 2 68 are each divided into a straight line portion and an arc portion. The geometric centers of the driving groove 1 67 and the driving groove 2 68 close to the center of the ring 64 are concentric with the ring 64, the supporting block 4 is close to the center of the ring 64 while the clamping block 5 is away from the center of the ring 64, and the telescopic end of the telescopic rod 31 is hinged to the rotating ring 63.

[0024] Specifically, in actual application, the fixed ring 61 is fixedly connected to the support assembly 3 by bolts, the annular protrusion 62 is provided at the lower end of the fixed ring 61, the rotating ring 63 is slidably connected to the annular protrusion 62 with a clearance fit, and the circular ring 64 is fixedly connected to the fixed ring 61 by bolts, and the rotating ring 63 is clamped between the fixed ring 61 and the circular ring 64; The extension of the telescopic rod 31 can drive the rotating ring 63 to rotate. The clockwise rotation of the rotating ring 63 can drive the driving groove 1 67 and the driving groove 2 68 and the pin 69, the supporting block 4 and the clamping block 5 to rotate relative to each other. Due to the restriction that the rectangular groove 1 65 and the rectangular groove 2 66 point to the center of the rotating ring 63, the supporting block 4 and the clamping block 5 can only move along the route pointing to the center of the rotating ring 63. The driving groove 1 67 and the driving groove 2 68 are both provided with an arc portion and a straight portion. The straight portion can drive the pin 69, the supporting block 4 and the clamping block 5 to move closer to or away from the retainer, and the arc portion can keep the pin 69, the supporting block 4 and the clamping block 5 stationary. like Figure 6 、 Figure 7 、 Figure 13 As shown, the initial position of the pin 69 on the supporting block 4 is located at the arc portion of the driving groove 1 67, and the initial position of the pin 69 on the clamping block 5 is located at the straight portion of the driving groove 2 68; The following describes in detail the movement of the supporting block 4 and the clamping block 5; The extension of the telescopic rod 31 is mainly divided into two stages; In the first stage, the telescopic rod 31 extends to drive the rotating ring 63 to rotate clockwise. The arc portion of the driving groove 1 67 does not drive the supporting block 4 to move, and the straight portion of the driving groove 2 68 drives the clamping block 5 to move toward the retainer. The clamping block 5 drives the rectangular protrusion 34 to clamp the second layer of retainer first. In the second stage, the straight part of driving groove 1 67 drives the supporting block 4 away from the retainer, and the arc part of driving groove 2 68 does not drive the clamping block 5 to move. The clamping block 5 remains in the state of clamping the second layer of retainer until the supporting platform 33 on the supporting block 4 releases the first layer of retainer.

[0025] The shortening of the telescopic rod 31 is mainly divided into two stages; In the first stage, the straight portion of the driving groove 1 67 drives the support block 4 to move closer to the holder, while the arc portion of the driving groove 2 68 does not drive the clamping block 5 to move, and the support platform 33 first moves to the position directly below the holder; In the second stage, the arc portion of the driving groove 1 67 does not drive the support block 4 to move, and the straight portion of the driving groove 2 68 drives the clamping block 5 and the rectangular protrusion 34 away from the retainer, releasing the retainer, and the stacked retainers fall onto the support platform 33; The above process is the complete process of releasing one retainer. Repeat the above work to release the retainers one by one.

[0026] The second embodiment of the linkage component 6, referring to Figure 8 、 Figure 9 、 Figure 10 The linkage component 6 includes a positioning ring 71 fixedly mounted on the support assembly 3. A limiting groove 1 72 and a limiting groove 2 73 are formed on the positioning ring 71. The supporting block 4 is located in the limiting groove 1 72, and the clamping block 5 is located in the limiting groove 2 73. A compression spring 1 74 is installed in each of the limiting groove 1 72 and the limiting groove 2 73. The compression spring 1 74 enables the supporting block 4 and the clamping block 5 to have potential energy away from the center of the ring 64. A pulley 75 is installed on one end of the supporting block 4 and the clamping block 5 away from the center of the ring 64. A bearing 76 is installed at the lower end of the positioning ring 71, and a rotating outer ring 77 is installed on the outer ring of the bearing 76. The telescopic end of the telescopic rod 31 is hinged to the rotating outer ring 77. An interference block 1 78 and an interference block 2 79 are installed on the inner side of the rotating outer ring 77 and are against the pulley 75. The interference block 1 78 rotates counterclockwise to move the supporting block 4 toward the center of the positioning ring 71, and the interference block 2 79 rotates counterclockwise to move the supporting block 4 away from the center of the positioning ring 71.

[0027] Specifically, in actual application, the positioning ring 71 is fixedly connected to the support assembly 3 by bolts, the rotating outer ring 77 is rotatably connected to the positioning ring 71 through the bearing 1 76, the compression spring 1 74 makes the supporting block 4 and the clamping block 5 have potential energy away from the center of the ring 64, and the pulley 75 is in close contact with the interference block 1 78 and the interference block 2 79; The extension of the telescopic rod 31 is mainly divided into two stages; In the first stage, the telescopic rod 31 extends to drive the rotating outer ring 77 to rotate clockwise. The arc portion of the interference block 1 78 does not drive the supporting block 4 to move, and the straight portion of the interference block 2 79 drives the clamping block 5 to move toward the retainer. The rectangular protrusion 34 on the clamping block 5 first clamps the second layer retainer. In the second stage, the straight part of the interference block 1 78 drives the supporting block 4 and the supporting platform 33 away from the retainer, and the arc part of the interference block 2 79 does not drive the clamping block 5 to move, and the rectangular protrusion 34 remains in the state of clamping the second layer of retainer until the supporting platform 33 releases the first layer of retainer.

[0028] The outer ring 77 rotates counterclockwise, and the telescopic rod 31 shortens in two main stages; In the first stage, the straight portion of the interference block 1 78 drives the support block 4 and the support platform 33 to move closer to the holder, while the arc portion of the interference block 2 79 does not drive the clamping block 5 to move. The support block 4 and the support platform 33 first move to the position directly below the holder; In the second stage, the arc portion of the interference block 1 78 does not drive the support block 4 to move, and the straight portion of the interference block 2 79 drives the clamping block 5 and the rectangular protrusion 34 away from the retainer, releasing the retainer, and the stacked retainers fall onto the support block 4; The above process is the complete process of releasing one retainer. Repeat the above work to release the retainers one by one.

[0029] Specifically, in practical applications, the arrangement of first driving the clamping block 5 to move and then driving the supporting block 4 to move can prevent the retainer from falling uncontrollably.

[0030] Reference Figure 1 、 Figure 2 、 Figure 11 and Figure 12 The support assembly 3 includes an L-shaped beam 11 installed on the workbench 1, a support rod 12 is installed on the L-shaped beam 11, and a support plate 13 is installed on the support rod 12. A second circular hole 14 is provided on the support plate 13, and a notch 15 is opened on one side of the second circular hole 14. The width of the notch 15 is smaller than the diameter of the second circular hole 14. A disc 16 is provided on the storage rod 2, and the diameter of the disc 16 is larger than the second circular hole 14. A circular protrusion 17 is installed on the lower surface of the disc 16, and the circular protrusion 17 is clearance-matched with the second circular hole 14.

[0031] Specifically in actual application, during normal use, the storage rod 2 is placed at the position of the second circular hole 14 through the action of the disc 16. When the number of retainers is insufficient, the storage rod 2 is lifted by hand, and the circular protrusion 17 moves to the position of the notch 15. At this time, the storage rod 2 can be removed by translation, and the pre-prepared storage rod 2 with sufficient retainers can be placed on the second circular hole 14.

[0032] Reference Figure 1 、 Figure 2 、 Figure 11 and Figure 12 The storage rod 2 is a hollow structure. Rectangular holes 21 are opened on both sides of the lower end of the storage rod 2. An L-shaped plate 22 is provided in the rectangular hole 21. The corners of the L-shaped plate 22 are hinged to the rectangular hole 21. A through hole 23 is opened at the upper end of the storage rod 2. A driving rod 24 is provided in the through hole 23. The driving rod 24 extends downward to the position of the rectangular hole 21. A limiting plate 25 is provided at the upper end of the driving rod 24. A compression spring 26 is installed between the driving rod 24 and the storage rod 2. A secondary connecting rod 27 is hingedly installed between the driving rod 24 and the L-shaped plate 22.

[0033] Specifically in actual application, in order to improve convenience, a person manually presses the drive rod 24, and the drive rod 24 drives the L-shaped plate 22 to rotate through the secondary connecting rod 27. The other side of the L-shaped plate 22 is stretched open to prevent the retainer from moving under the action of gravity. The movement of the storage rod 2 can be operated by one hand (previously operated by two hands). The person manually releases the drive rod 24, and the L-shaped plate 22 is reset through the action of the compression spring 26, and the retainer can fall freely.

[0034] Reference Figure 8 A flexible rod 321 is installed on the circular hole 1 32.

[0035] Specifically, in practical applications, through the action of the flexible rod 321, when the storage rod 2 is withdrawn, the retainer on the linkage component 6 can maintain a stable stacking state to avoid tilting; In actual operation, the inner ring and outer ring are combined first, then the lower retainer is placed, then the balls are placed, and finally the upper retainer is placed.
