Description

Technical Field

[0001] This invention relates to the field of lubrication column bonding device technology, and more specifically, to an embedded self-lubricating bearing lubrication column bonding device and process. Background Technology

[0002] Embedded self-lubricating bearings, with their high load-carrying capacity and excellent self-lubricating properties, are widely used in harsh operating conditions such as low-speed heavy loads, intermittent motion, and where oil film formation is difficult. The core function of these bearings relies on lubricating pillars embedded in the bearing body's mounting holes. The adhesion quality between these pillars and the bearing substrate directly determines the product's friction coefficient stability, wear life, and overall reliability. The bonding of these lubricating pillars is a critical process in the production of embedded self-lubricating bearings, with stringent process requirements. Since a single bearing typically requires dozens of lubricating pillars, and the protrusion dimensions of each pillar must strictly match the design values ​​to avoid assembly interference or lubrication failure.

[0003] However, the industry currently relies primarily on manual positioning and bonding for this process, supplemented by simple tooling. Traditional positioning devices only fix the bearing externally. During bonding, manual operation depends on experience to judge the insertion depth of the lubricating post, which is difficult to handle individual bearing differences in mass production. The bearing is prone to radial displacement due to uneven force, leading to accumulated positional deviations in each insert hole. Ultimately, this results in inconsistent protrusion lengths on the inner and outer diameter sides after the lubricating post is inserted. In severe cases, functional defects occur, such as the inner diameter side protruding and obstructing shaft assembly, or the outer diameter side being too short and affecting lubrication contact. This leads to a high scrap rate and significantly increases processing costs. Summary of the Invention

[0004] This invention provides a bonding device and process for embedded self-lubricating bearing lubricating columns, solving the technical problem in related technologies where manual operation during the bonding process relies on experience to judge the insertion depth of the lubricating column, leading to the accumulation of positional deviations in each embedding hole, and ultimately causing inconsistent extension lengths on the inner and outer diameter sides of the lubricating column after insertion, which significantly increases processing costs.

[0005] The first aspect of the present invention discloses an embedded self-lubricating bearing lubrication column bonding device, which is used to position the self-lubricating bearing during the bonding process of the lubrication column. The self-lubricating bearing has a plurality of embedding holes for bonding the lubrication column, and includes a base on which the self-lubricating bearing is placed.

[0006] An inner positioning unit and an outer positioning unit are provided. The inner positioning unit is located inside the self-lubricating bearing, and the outer positioning unit is located outside the self-lubricating bearing. The inner positioning unit and the outer positioning unit are used to position and fix the self-lubricating bearing, and a gap is provided between the inner positioning unit and the self-lubricating bearing.

[0007] When the lubricating post is inserted into the insert hole, the insertion size of the lubricating post is fixed by setting the gap to prevent the lubricating post from protruding too far into the inner diameter of the self-lubricating bearing, resulting in the outer diameter not being fully exposed, or the lubricating post protruding too far into the outer diameter of the self-lubricating bearing, resulting in the inner diameter not being fully exposed, thus producing scrap.

[0008] As a further optimization of the present invention, the inner positioning unit includes a first inner positioning mechanism, the first inner positioning mechanism includes a spindle located inside the self-lubricating bearing, and a positioning post is provided inside the spindle. The base has a second positioning hole inside, and the second positioning hole is slidably connected to the positioning post.

[0009] As a further optimization of the present invention, the distance from the lower end face of the positioning post to the upper surface of the base is L1, and the distance from the upper surface of the base to the upper end face of the self-lubricating bearing is L2; ​​wherein, the length of L1 is greater than the length of L2, and when the L2 length portion of the mandrel exits the self-lubricating bearing, the mandrel can be completely exited under the limiting action of the L1 length portion of the positioning post and the second positioning hole.

[0010] As a further optimization of the present invention, the external positioning unit includes a first external positioning mechanism, the first external positioning mechanism includes an outer diameter positioning disk located outside the self-lubricating bearing, and the outer diameter positioning disk has multiple sets of through holes, the base has pin holes corresponding to the positions of the multiple sets of through holes, and a positioning pin is inserted between the through holes and the pin holes.

[0011] As a further optimization of the present invention, the inner positioning unit includes a second inner positioning mechanism, which includes multiple sets of first inner diameter positioning blocks evenly distributed in a ring on the base. Each set of first inner diameter positioning blocks has a second inner diameter positioning block on both sides. The first inner diameter positioning blocks and the second inner diameter positioning blocks are used to position and fix the size of the lubricating column insertion.

[0012] As a further optimization of the present invention, guide grooves are provided on both sides of the interior of the first inner diameter positioning block, and a movable rod is slidably connected in the guide groove. The movable rod is fixedly connected to the second inner diameter positioning block, and a first spring is also provided on the outside of the movable rod.

[0013] As a further optimization of the present invention, multiple sets of the first inner diameter positioning blocks and the second inner diameter positioning blocks form a ring structure. A conical block is provided at the center of the ring. Multiple sets of inclined blocks are provided around the conical block. The multiple sets of inclined blocks are fixedly connected to the corresponding first inner diameter positioning blocks. A pull rod is installed on the conical block, and the pull rod extends through the base to the lower surface of the base. A first electric push rod is installed on the base, and the telescopic end of the first electric push rod is fixedly connected to the pull rod through a bracket.

[0014] As a further optimization of the present invention, the base is provided with an opening for the circular structure to pass through, a support frame is provided in the opening, a second electric push rod is installed on the base, and the telescopic end of the second electric push rod is connected to the support frame through a connecting frame.

[0015] As a further optimization of the present invention, the external positioning unit includes a second external positioning mechanism, which includes positioning plates and adjusting bolts disposed on both sides of the self-lubricating bearing. The position of the positioning plates is adjusted by the adjusting bolts to adapt to self-lubricating bearings with different outer diameters.

[0016] The second aspect of this invention discloses a bonding process for embedded self-lubricating bearing lubrication posts, using an embedded self-lubricating bearing lubrication post bonding device as described above, comprising the following steps:

[0017] S1. Place the self-lubricating bearing with several inlay holes on the base;

[0018] S2. The self-lubricating bearing is positioned and fixed by the inner positioning unit located inside the self-lubricating bearing and the outer positioning unit located outside the self-lubricating bearing, and a preset gap is maintained between the inner positioning unit and the self-lubricating bearing.

[0019] S3. Insert the lubricating post into the mounting hole of the self-lubricating bearing, and use the preset gap to limit the insertion size of the lubricating post;

[0020] S4. Bond and fix the lubricating post inserted into the mounting hole.

[0021] The beneficial effects of this invention are as follows: By designing the gap between the inner positioning unit and the self-lubricating bearing, this invention directly limits the maximum extension length of the lubricating column in both the inner and outer diameter directions of the bearing, fundamentally avoiding functional interference caused by excessive extension of the lubricating column, and effectively solving the problem of uncontrolled lubricating column dimensions in traditional positioning methods. Furthermore, through the coordinated positioning effect of the inner and outer positioning units, a rigid constraint is formed in both directions of the bearing's inner and outer diameters, ensuring no radial displacement of the bearing during bonding. This guarantees the consistency of the lubricating column insertion dimensions, significantly reducing the scrap rate caused by dimensional deviations. Compared to traditional manual positioning or single-direction positioning processes, this reduces the scrap rate. Attached Figure Description

[0035] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0036] Example 1: According to the appendix Figure 1 As shown, an embedded self-lubricating bearing lubrication column bonding device is used to position the self-lubricating bearing 2 during the bonding process of the lubrication column. The self-lubricating bearing 2 has several embedding holes 3 for bonding the lubrication column, including a base 1 and a pad 4. The self-lubricating bearing 2 is placed on the base 1; the pad 4 is set on both sides of the bottom of the base 1.

[0037] The core of this device lies in its positioning function, which includes an inner positioning unit and an outer positioning unit. The inner positioning unit is located inside the self-lubricating bearing 2 and is used to position it from the direction of the bearing's inner diameter. The outer positioning unit is located outside the self-lubricating bearing 2 and is used to position it from the direction of the bearing's outer diameter. The inner and outer positioning units work together to position and fix the self-lubricating bearing 2, ensuring its accurate position during the bonding process.

[0038] A gap is provided between the inner positioning unit and the self-lubricating bearing 2. This gap is crucial for achieving precise dimensional control. When the lubricating post is inserted into the insert hole 3, this gap ensures that the insertion size of the lubricating post is fixed.

[0039] Specifically, the gap limits the extension length of the lubricating column in the direction of the inner or outer diameter of the self-lubricating bearing 2, thereby preventing the lubricating column from extending too far in the inner diameter of the self-lubricating bearing 2, resulting in the outer diameter not being fully exposed, or the lubricating column from extending too far in the outer diameter of the self-lubricating bearing 2, resulting in the inner diameter not being fully exposed, effectively avoiding scrap caused by improper insertion size of the lubricating column.

[0040] In one embodiment, according to the appendix Figure 2 Appendix Figure 3 and attached Figure 4 As shown, the inner positioning unit includes a first inner positioning mechanism 5, which includes a spindle 51 located inside the self-lubricating bearing 2, and a positioning post 52 is provided inside the spindle 51. The base 1 has a second positioning hole 54 inside, and the second positioning hole 54 is slidably connected to the positioning post 52.

[0041] The mandrel 51 has a first positioning hole 53 inside that matches the positioning post 52. The first positioning hole 53 also has a threaded hole inside, and the threaded hole and the positioning post 52 are connected by a thread. The threaded connection makes the connection between the positioning post 52 and the mandrel 51 more secure and reliable, and also facilitates the installation and disassembly of the positioning post 52, the replacement of mandrels 51 of different sizes, and the fine adjustment when needed.

[0042] Furthermore, the distance from the lower end face of the positioning post 52 to the upper surface of the base 1 is L1, and the distance from the upper surface of the base 1 to the upper end face of the self-lubricating bearing 2 is L2; ​​wherein, the length of L1 is greater than the length of L2. When the L2-length portion of the mandrel 51 exits the self-lubricating bearing 2, because L1 is greater than L2, the L1-length portion of the positioning post 52 can still maintain a limiting effect with the second positioning hole 54. This ensures that the positioning post 52 is always guided and supported by the second positioning hole 54 before the mandrel 51 completely disengages from the self-lubricating bearing 2, allowing the mandrel 51 to exit smoothly and completely, avoiding jamming or tilting problems, and improving the smoothness and efficiency of operation.

[0043] In yet another embodiment, according to the appendix Figure 2 and attached Figure 3 As shown, the external positioning unit includes a first external positioning mechanism 6, which includes an outer diameter positioning disc 61 located outside the self-lubricating bearing 2. The outer diameter positioning disc 61 has multiple sets of through holes, and the base 1 has pin holes corresponding to the positions of these through holes. Positioning pins 62 are inserted between the through holes and the pin holes. By inserting the positioning pins 62, the outer diameter positioning disc 61 can be precisely fixed to the base 1, thereby achieving precise external fixation of the self-lubricating bearing 2.

[0044] Working principle: Place the pad 4 on the platform and place the base 1 on the pad 4. Then insert the positioning pin 52 into the second positioning hole 54 and slide it through the second positioning hole 54.

[0045] Subsequently, the mandrel 51 is threaded to the positioning post 52, and the mandrel 51 and the positioning post 52 are clearance-fitted through the first positioning hole 53, which facilitates screwing.

[0046] Finally, the outer diameter positioning disc 61 is installed on the base 1, and the positioning connection between the outer diameter positioning disc 61 and the base 1 is achieved by two staggered positioning pins 62.

[0047] When bonding the lubricating post into the insert hole 3 of the self-lubricating bearing 2, the self-lubricating bearing 2 is positioned in the outer diameter positioning plate 61 to ensure the clearance between the self-lubricating bearing 2 and the mandrel 51. This clearance limits the extension length of the lubricating post in the inner or outer diameter direction of the self-lubricating bearing 2, preventing the lubricating post from extending too far into the inner diameter of the self-lubricating bearing 2, thus preventing the outer diameter from not being fully exposed, or vice versa. This effectively avoids defective products due to improper insertion size of the lubricating post. The clearance setting position is shown in the attached figure. Figure 2 As shown in the L3 position.

[0048] Example 2: According to the appendix Figure 5 As shown, an embedded self-lubricating bearing lubrication column bonding device is used to position the self-lubricating bearing 2 during the bonding process of the lubrication column. The self-lubricating bearing 2 has several embedding holes 3 for bonding the lubrication column, including a base 1 and a pad 4. The self-lubricating bearing 2 is placed on the base 1; the pad 4 is set on both sides of the bottom of the base 1.

[0049] The core of this device lies in its positioning function, which includes an inner positioning unit and an outer positioning unit. The inner positioning unit is located inside the self-lubricating bearing 2 and is used to position it from the direction of the bearing's inner diameter. The outer positioning unit is located outside the self-lubricating bearing 2 and is used to position it from the direction of the bearing's outer diameter. The inner and outer positioning units work together to position and fix the self-lubricating bearing 2, ensuring its accurate position during the bonding process.

[0050] A gap is provided between the inner positioning unit and the self-lubricating bearing 2. This gap is crucial for achieving precise dimensional control. When the lubricating post is inserted into the insert hole 3, this gap ensures that the insertion size of the lubricating post is fixed.

[0051] Specifically, the gap limits the extension length of the lubricating column in the direction of the inner or outer diameter of the self-lubricating bearing 2, thereby preventing the lubricating column from extending too far in the inner diameter of the self-lubricating bearing 2, resulting in the outer diameter not being fully exposed, or the lubricating column from extending too far in the outer diameter of the self-lubricating bearing 2, resulting in the inner diameter not being fully exposed, effectively avoiding scrap caused by improper insertion size of the lubricating column.

[0052] In one embodiment, according to the appendix Figure 6 and attached Figure 7 As shown, the inner positioning unit includes a second inner positioning mechanism 7. The second inner positioning mechanism 7 includes multiple sets of first inner diameter positioning blocks 71 that are evenly distributed in a ring on the base 1. Each set of first inner diameter positioning blocks 71 has a second inner diameter positioning block 72 on both sides. The first inner diameter positioning blocks 71 and the second inner diameter positioning blocks 72 are used to position and fix the size of the lubricating column insertion.

[0053] The annular distribution of multiple sets of first inner diameter positioning blocks 71 and second inner diameter positioning blocks 72 can control the distance between the self-lubricating bearing 2 and the first inner diameter positioning blocks 71 and second inner diameter positioning blocks 72, and indirectly control the insertion size of the lubrication column.

[0054] In addition, according to the appendix Figure 8 Appendix Figure 9 and attached Figure 10 As shown, guide grooves are provided on both sides of the interior of the first inner diameter positioning block 71, and a movable rod 711 is slidably connected within the guide grooves. The movable rod 711 is fixedly connected to the second inner diameter positioning block 72. A first spring 712 is also provided outside the movable rod 711. One end of the first spring 712 is connected to the guide groove, and the other end of the first spring 712 is connected to the movable rod 711. In this embodiment, the second inner diameter positioning block 72 can slide within the guide groove via the movable rod 711 and achieve elastic positioning or reset under the action of the first spring 712, thereby adapting to self-lubricating bearings 2 of different sizes.

[0055] Furthermore, according to the appendix Figure 11 As shown, multiple sets of first pads 713 are installed on the side of each set of first inner diameter positioning blocks 71 away from the center, and two sets of second pads 714 are provided between every two sets of first pads 713. Each pair of second pads 714 is fixedly connected to the corresponding second inner diameter positioning block 72. In this embodiment, the first pads 713 and the second pads 714 are used to fill the gaps in the contact area of ​​the lubrication column, ultimately forming a continuous and uniform contact interface, thereby ensuring the insertion size of the lubrication column.

[0056] Specifically, according to the appendix Figure 8 Appendix Figure 9 and attached Figure 11 As shown, multiple sets of first inner diameter positioning blocks 71 and second inner diameter positioning blocks 72 form a ring structure. A conical block 73 is provided at the center of the ring. Multiple sets of inclined blocks 74 are provided around the conical block 73. The multiple sets of inclined blocks 74 are fixedly connected to the corresponding first inner diameter positioning blocks 71. A pull rod 75 is installed on the conical block 73, and the pull rod 75 extends through the base 1 to the lower surface of the base 1. A first electric push rod 76 is installed on the base 1, and the telescopic end of the first electric push rod 76 is fixedly connected to the pull rod 75 through a bracket.

[0057] When the first electric push rod 76 drives the pull rod 75 to move up and down, the conical block 73 will move accordingly. Since the inclined block 74 is in contact with the inclined surface of the conical block 73, the up and down movement of the conical block 73 will transmit the force to the first inner diameter positioning block 71 through the inclined block 74, causing it to move radially inward or outward, thereby enlarging or reducing the diameter. This makes it easy to adjust the distance between the self-lubricating bearing 2 and the first inner diameter positioning block 71 and the second inner diameter positioning block 72 according to the size of the self-lubricating bearing 2, thereby facilitating the fixing of the insertion size of the lubrication column.

[0058] In yet another embodiment, according to the appendix Figure 8 and attached Figure 9 As shown, the base 1 has an opening for the circular structure to pass through. A support frame 77 is installed within the opening, and a support plate 78 is mounted on the support frame 77. The support plate 78 has multiple sets of sliding grooves 781 arranged in a ring, matching the number of the first inner diameter positioning blocks 71. A sliding rod 782 is slidably connected inside each groove 781, and the sliding rod 782 is fixedly connected to the first inner diameter positioning block 71. A second spring 783 is installed between the groove 781 and the sliding rod 782. In this embodiment, the first inner diameter positioning block 71 can slide smoothly within the groove 781 of the support plate 78 via the sliding rod 782. The second spring 783 provides elastic support and a restoring force, ensuring smooth movement and precise positioning of the positioning block.

[0059] When the first inner diameter positioning block 71 moves radially under the thrust of the inclined block 74, the slide rod 782 slides synchronously along the slide groove 781, ensuring that the positioning block only moves in a straight line in the radial direction, avoiding lateral offset or torsion, and improving motion accuracy.

[0060] It should be noted that the elastic force of the second spring 783 is greater than that of the first spring 712.

[0061] The second spring 783 serves as the main reset element, and its elastic force is greater than that of the first spring 712. When the conical block 73 releases the squeezing control, the contraction force of the second spring 783 dominates the reset of the first inner diameter positioning block 71, ensuring that it returns to the reference position; the first spring 712 assists the second inner diameter positioning block 72 in resetting.

[0062] In yet another embodiment, according to the appendix Figure 8 As shown, a second electric push rod 79 is mounted on the base 1, and the telescopic end of the second electric push rod 79 is connected to the support frame 77 via a connecting frame 791. In this embodiment, the telescopic movement of the second electric push rod 79 can drive the support frame 77 and its positioning mechanism to rise and fall as a whole, facilitating the placement and removal of the self-lubricating bearing 2, and further improving the automation and efficiency of the operation.

[0063] The second electric push rod 79 drives the support frame 77 to rise and fall along the opening axis through the connecting frame 791, thereby driving the support plate 78, the first inner diameter positioning block 71, the second inner diameter positioning block 72, and other components to rise and fall synchronously.

[0064] When rising, the second inner positioning mechanism 7 extends into the inner diameter area of ​​the self-lubricating bearing 2 to achieve the function of lubricating column bonding and positioning; when falling, the second inner positioning mechanism 7 completely disengages from the inner diameter of the self-lubricating bearing 2, releasing the operating space of the self-lubricating bearing 2, which facilitates the removal, placement and replacement of the self-lubricating bearing 2.

[0065] In yet another embodiment, according to the appendix Figure 6 As shown, the external positioning unit includes a second external positioning mechanism 8. The second external positioning mechanism 8 includes positioning plates 81 and adjusting bolts 82 disposed on both sides of the self-lubricating bearing 2. The adjusting bolts 82 are connected to the bearing of the base 1 through the bearing, and the positioning plates 81 and the adjusting bolts 82 are threadedly connected. In this embodiment, by rotating the adjusting bolts 82, the positioning plates 81 can be driven to move radially, thereby achieving precise clamping or loosening of the outer diameter of the self-lubricating bearing 2. The positioning plates 81 can also be driven by telescopic elements such as electric push rods or cylinders.

[0066] In yet another embodiment, according to the appendix Figure 8 As shown, the auxiliary disengagement mechanism 9 includes a second gear 93 that is slidably connected to the outside of the pull rod 75, and the second gear 93 is fixedly connected to the support frame 77. A motor 91 is mounted on the connecting frame 791, and the output shaft of the motor 91 passes through the support frame 77 to mount a first gear 92. The first gear 92 and the second gear 93 are meshed together.

[0067] When the motor 91 starts, its output shaft drives the first gear 92 to rotate. The first gear 92, through meshing with the second gear 93, drives the second gear 93 to rotate. Since the second gear 93 is fixedly connected to the support frame 77, it drives the first inner diameter positioning block 71 and the second inner diameter positioning block 72 to rotate.

[0068] At this time, the first inner diameter positioning block 71 and the second inner diameter positioning block 72 generate relative rotational motion with the lubrication column. The contact surfaces that may have been stuck together by the adhesive are forcibly separated, thereby releasing the physical adsorption or chemical bonding state and avoiding adhesion with the first inner diameter positioning block 71 and the second inner diameter positioning block 72.

[0069] In this embodiment, the relative rotational movement of the first inner diameter positioning block 71 and the second inner diameter positioning block 72 with the lubricating column can break the adhesive force formed by adhesive overflow or surface tension between them. Compared with the traditional axial insertion and removal method, this reduces the probability of component damage caused by adhesion, and is especially suitable for scenarios where low-viscosity adhesives detach in the early stages of curing. Specifically, the shear force generated by the rotational detachment method is evenly distributed on the contact surface, avoiding the skewing, breakage, or deformation of the positioning block that may be caused by direct pulling, ensuring that the insertion dimension accuracy of the lubricating column is not affected.

[0070] In yet another embodiment, according to the appendix Figure 12 As shown, the cleaning mechanism 10 includes a brush 101 disposed in the opening, and a toothed ring 102 is mounted on the brush 101. A third gear 103 is meshed on the toothed ring 102, and a splined shaft 104 is mounted on the third gear 103. The splined shaft 104 extends through the base 1 to the lower surface of the base 1. The splined shaft 104 and the base 1 are rotatably connected by a bearing. A bushing 105 is slidably connected on the splined shaft 104, and the bushing 105 is connected to the output shaft of the motor 91 through a belt pulley transmission mechanism 106. Connecting plates 107 are provided on both the upper and lower sides of the belt pulley transmission mechanism 106. The connecting plates 107 are rotatably connected to the bushing 105 and the output shaft of the motor 91 through bearings.

[0071] When motor 91 is working, its output shaft drives the bushing 105 and splined shaft 104 to rotate via belt pulley transmission mechanism 106. Splined shaft 104 drives third gear 103 to rotate, and third gear 103 meshes with gear ring 102, thereby driving brush 101 to rotate. Utilizing the elastic deformation of the bristles, the brush penetrates deep into crevices and surface depressions to peel off and clean residual adhesive debris, dust, and other impurities, effectively cleaning adhesive residue from the inner wall of the opening and the outside of the self-lubricating bearing 2, preventing impurities from affecting the bonding quality.
