Description

Technical Field

[0001] This invention relates to the field of inlay device technology, and more specifically, to an inlay device for lubricating pillars in the machining of self-lubricating bearings. Background Technology

[0002] Self-lubricating bearings are widely used in engineering machinery, automotive parts, and other fields due to their advantage of requiring no additional lubrication maintenance. Their core performance relies on internally embedded lubrication pillars. These pillars are fixed in place by creating mounting holes in the bearing body, achieving long-term self-lubrication. A crucial step in the manufacturing process of self-lubricating bearings is precisely and securely embedding the lubrication pillars into the pre-set mounting holes in the bearing body.

[0003] In existing technologies, the embedding of lubrication posts in self-lubricating bearings is typically achieved through bonding. During the bonding process, adhesives or glue used for bonding may overflow or remain on the mandrel surface. If not cleaned promptly, this can affect the accuracy and efficiency of subsequent processing and even contaminate the product. Some existing embedding devices are inadequate in cleaning debris and adhesive residue, exhibiting low cleaning efficiency, complex operation, and difficulty in ensuring thorough cleaning, thus impacting the overall processing quality and production efficiency of self-lubricating bearings. Summary of the Invention

[0004] This invention provides a lubrication post embedding device for processing self-lubricating bearings, which solves the technical problem in related technologies where glue or adhesive used for bonding may overflow or remain on the surface of the mandrel during the bonding process. If not cleaned in time, this can affect the accuracy and efficiency of subsequent processing and even contaminate the product.

[0005] This invention provides a lubrication post embedding device for processing self-lubricating bearings, used for embedding self-lubricating bearings. The self-lubricating bearing has a plurality of embedding holes for bonding lubrication posts inside. The device includes a device body, which includes a worktable. A base is provided above the worktable. The self-lubricating bearing is placed on the base. A mandrel is provided on the base and is located inside the self-lubricating bearing.

[0010] As a further optimization of the present invention, the cleaning unit includes an annular support disposed inside the air chamber, and the annular support is provided with connecting shafts in the circumferential direction in the same number as the number of chip removal ports. The annular support and the connecting shafts are rotatably connected by bearings. A cleaning brush is installed at one end of each connecting shaft near the chip removal port, and the cleaning brush passes through the inside of the chip removal port to clean the inside of the chip removal port.

[0011] As a further optimization of the present invention, each set of connecting shafts is equipped with a gear, the annular bracket is provided with a toothed ring inside, the gear and the toothed ring are meshed together, the annular bracket is also provided with a rod sleeve inside, and multiple sets of fixing brackets are installed between the rod sleeve and the toothed ring.

A reciprocating rod is slidably connected inside the rod sleeve, and the reciprocating rod is fixedly connected to the inner wall of the air chamber.

[0012] As a further optimization of the present invention, a second spring is provided on the outside of the reciprocating rod, and one end of the second spring is fixedly connected to the inner wall of the air cavity, and the other end of the second spring is fixedly connected to the fixing plate.

[0013] As a further optimization of the present invention, the connecting pipe is symmetrically equipped with push rods. When the mandrel moves downward along the inside of the port, the fixing plate contacts the push rod, controlling the cleaning unit to move upward inside the air chamber to clean the inside of the chip removal port.

[0014] As a further optimization of the present invention, the base has an annular inclined groove inside, and the annular inclined groove is connected to the inside of the through-hole.

Detailed Implementation

[0027] 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.

[0028] According to the appendix Figure 1 As shown, a lubrication post inserting device for machining a self-lubricating bearing 140 is used for inserting the self-lubricating bearing 140. The self-lubricating bearing 140 has several inserting holes 150 for bonding the lubrication posts. This inserting device aims to solve the problems of residual dust inside the inserting holes 150 and incomplete cleaning of residual debris and adhesive residue after bonding in the prior art, thereby improving the inserting quality and efficiency.

[0029] Example 1: According to the appendix Figure 1 and attached Figure 2 As shown, a lubrication post embedding device for machining a self-lubricating bearing 140 according to the present invention includes a device body 100, the device body 100 including a worktable 110, and a base 120 disposed above the worktable 110. During embedding, the self-lubricating bearing 140 to be machined is placed on the base 120. Two sets of pads 130 are symmetrically arranged between the worktable 110 and the base 120.

[0030] The base 120 is provided with a spindle 160, which is located inside the self-lubricating bearing 140. The base 120 has an opening for the spindle 160 to pass through. The base 120 is also provided with an outer diameter positioning plate 170, which is located outside the self-lubricating bearing 140.

[0031] It should be understood that the self-lubricating bearing 140 to be processed is placed on the base 120, and the mandrel 160 is inserted into the inner hole of the self-lubricating bearing 140 to achieve inner diameter centering; the outer diameter positioning plate 170 fits against the outer circle of the self-lubricating bearing 140 to achieve outer diameter limiting.

[0032] The radial position of the self-lubricating bearing 140 is limited and fixed by the dual constraints of the spindle 160 and the outer diameter positioning plate 170, ensuring the alignment effect between the inlay hole 150 and the subsequent lubrication post inlay mechanism.

[0033] It is important to note that the self-lubricating bearing 140 is positioned and fixed by the outer diameter positioning plate 170. A gap exists between the self-lubricating bearing 140 and the mandrel 160. This gap is used to limit the insertion size of the lubricating column, ensuring a consistent insertion size. In subsequent production, the lubricating columns can be manufactured according to this size, thereby reducing wear and production costs.

[0034] According to the appendix Figure 1 Appendix Figure 2 and attached Figure 3 As shown, the inlay device also includes a chip removal unit 200. The chip removal unit 200 includes a plurality of chip removal ports 210 evenly opened along the circumference of the mandrel 160, a gas transmission pipe 220 installed on the mandrel 160, and a connecting pipe 230 disposed below the gas transmission pipe 220. A movable pipe 240 is slidably connected to one end of the connecting pipe 230 near the gas transmission pipe 220, and a pipe joint 250 is installed at the other end of the connecting pipe 230 away from the gas transmission pipe 220.

[0035] It is important to note that the movable tube 240 and the gas transmission tube 220 are connected by a thread. The connecting tube 230 has multiple sets of limiting grooves 280 inside, and limiting blocks are slidably connected inside the limiting grooves 280. The limiting blocks are fixedly connected to the movable tube 240. The limiting grooves 280 and the limiting blocks facilitate the threaded connection between the movable tube 240 and the gas transmission tube 220.

[0036] Specifically, a connecting frame 260 is installed on the connecting pipe 230, and the connecting frame 260 is fixedly connected to the worktable 110. Electric push rods 270 are installed on both sides inside the connecting frame 260, and the telescopic ends of the electric push rods 270 are fixedly connected to the spindle 160. By extending and retracting the electric push rods 270, the lifting and lowering of the spindle 160 can be precisely controlled, thereby achieving automatic loading, unloading, and positioning of the self-lubricating bearing 140, improving the automation level and ease of operation of the device.

[0037] It should be understood that when the bearing needs to be clamped, the electric push rod 270 retracts, driving the spindle 160 to move downward along the opening of the base 120. The top of the spindle 160 is lower than the table surface of the base 120, which facilitates the quick placement of the bearing.

[0038] After the bearing is placed, the electric push rod 270 extends, pushing the mandrel 160 upward until the mandrel 160 and the outer diameter positioning plate 170 clamp the bearing together; after processing, the electric push rod 270 retracts again, and the mandrel 160 descends, making it easier to remove the bearing and reducing the intensity of manual operation.

[0039] In one embodiment, according to the appendix Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the mandrel 160 has an air cavity inside, and the air cavity is connected to the inside of the chip removal port 210.

[0040] It should be noted that during chip removal, the external dust removal equipment is connected to the connecting pipe 230 through the pipe joint 250, which creates negative pressure in the air chamber inside the mandrel 160, sucking in the dust outside the chip removal port 210 and thoroughly blowing away the dust, processing debris, and adhesive residue left in the previous bonding process in the mounting hole 150.

[0041] It should be noted that a first spring 290 is installed between the connecting tube 230 and the movable tube 240. The function of the first spring 290 is to provide a restoring force for the movable tube 240, ensuring a good sliding connection between the movable tube 240 and the connecting tube 230 when the spindle 160 moves. Furthermore, the first spring 290 allows the movable tube 240 to remain extended even when it is not threadedly connected to the gas transmission tube 220, thus ensuring the sealing and stability of the gas path.

[0042] Example 2: According to the appendix Figure 2 and attached Figure 5 As shown, based on the above embodiments, in order to further improve the chip removal effect and the ease of maintenance of the device, the present invention also provides a cleaning unit 300.

[0043] According to the appendix Figure 5 As shown, a cleaning unit 300 is provided inside the air chamber to clean the inside of the chip removal port 210, preventing the chip removal port 210 from being blocked by accumulated debris and affecting the chip removal effect.

[0044] In one embodiment, according to the appendix Figure 6 and attached Figure 7 As shown, the cleaning unit 300 includes an annular support 310 disposed inside the air chamber, and the annular support 310 is provided with the same number of connecting shafts 320 as the chip removal ports 210 along the circumferential direction. The annular support 310 and the connecting shafts 320 are rotatably connected by bearings, so that the connecting shafts 320 can rotate freely.

[0045] Each connecting shaft 320 is equipped with a cleaning brush 330 at one end near the chip removal port 210, and the cleaning brush 330 passes through the inside of the chip removal port 210 to clean the inside of the chip removal port 210. When the cleaning unit 300 moves in the air chamber, the cleaning brush 330 scrapes the inner wall of the chip removal port 210 to remove the attached debris.

[0046] To achieve the rotating cleaning action of the cleaning brush 330, according to the attached... Figure 5 and attached Figure 7 As shown, it should be explained in detail that each set of connecting shafts 320 is equipped with a gear 340, and the annular bracket 310 is provided with a toothed ring 350. The gear 340 and the toothed ring 350 are meshed together. When the gear 340 and the toothed ring 350 mesh and rotate, the gear 340 will drive the connecting shaft 320 and the cleaning brush 330 to rotate, thereby achieving effective brushing and cleaning of the chip removal port 210.

[0047] The annular bracket 310 is also provided with a rod sleeve 360 ​​inside, and multiple sets of fixing brackets 370 are installed between the rod sleeve 360 ​​and the toothed ring 350. Fixing plates are installed on both the upper and lower sides of the annular bracket 310, and the fixing plates are rotatably connected to the rod sleeve 360 ​​through bearings. A reciprocating rod 380 is slidably connected inside the rod sleeve 360, and the reciprocating rod 380 is fixedly connected to the inner wall of the air chamber.

[0048] Furthermore, a second spring 390 is provided on the outside of the reciprocating rod 380, with one end of the second spring 390 fixedly connected to the inner wall of the air chamber and the other end of the second spring 390 fixedly connected to the fixing plate. The function of the second spring 390 is to provide a reset force for the cleaning unit 300, so that the cleaning unit 300 can automatically reset to the initial position after the spindle 160 moves, preparing for the next cleaning.

[0049] In this embodiment, traditional high-pressure dust removal can easily lead to the accumulation of fine debris on the inner wall of the dust removal port 210. Long-term use will narrow the air passage, reduce the blowing pressure, or even completely block it. The cleaning unit 300 ensures that the dust removal port 210 is always unobstructed through dual cleaning of axial scraping and circumferential brushing.

[0050] In yet another embodiment, according to the appendix Figure 4 As shown, push rods 500 are symmetrically installed inside the connecting pipe 230. When the spindle 160 moves downward along the inside of the opening, the fixing plate contacts the push rod 500, controlling the cleaning unit 300 to move upward inside the air chamber to clean the inside of the chip removal port 210.

[0051] It should be noted that, according to the appendix Figure 4 To be continued Figure 7As shown, after the self-lubricating bearing 140 is processed, the electric push rod 270 retracts, and the spindle 160 moves downward along the opening of the base 120; during the descent of the spindle 160, the annular bracket 310 inside its air chamber moves downward synchronously with the spindle 160.

[0052] When the mandrel 160 descends, the fixing plate on the lower side of the annular bracket 310 contacts the push rod 500 inside the connecting pipe 230. As the mandrel 160 continues to descend, the push rod 500 generates an upward reaction force on the fixing plate, pushing the annular bracket 310 to move upward relative to the air chamber of the mandrel 160. At this time, the mandrel 160 moves downward and the annular bracket 310 moves upward.

[0053] When the annular bracket 310 moves upward relative to the air chamber, it drives the connecting shaft 320 and the cleaning brush 330 to move upward synchronously. The cleaning brush 330 slides axially along the inner wall of the chip removal port 210, scraping off the blocky debris or adhesive residue attached to the hole wall of the chip removal port 210, and removing large areas of residue.

[0054] When the annular support 310 moves upward, the central sleeve 360 ​​slides upward along the fixed reciprocating rod 380. The spiral guide groove on the outside of the reciprocating rod 380 forces the sleeve 360 ​​to rotate circumferentially. The sleeve 360 ​​drives the gear ring 350 to rotate synchronously through the fixed frame 370. The gear ring 350 meshes with the gear 340 to drive the connecting shaft 320 and the cleaning brush 330 to rotate circumferentially. The rotating cleaning brush 330 brushes the inner wall of the chip removal port 210 to remove small debris or stubborn adhesive residue left by axial scraping, and completely avoids clogging of the chip removal port 210.

[0055] After the self-lubricating bearing 140 is removed, the electric push rod 270 extends and the spindle 160 moves upward along the opening. When the spindle 160 rises, the reaction force of the push rod 500 on the fixing plate of the annular bracket 310 disappears, the second spring 390 releases the stored reset force, and pushes the annular bracket 310 to move downward relative to the air chamber, returning to the initial position at the bottom of the air chamber.

[0056] As the annular support 310 moves downward, the sleeve 360 ​​slides downward along the reciprocating rod 380 and rotates in the opposite direction under the action of the spiral guide groove, driving the cleaning brush 330 to brush the chip removal port 210 in the opposite direction for secondary cleaning.

[0057] Example 3: According to the appendix Figure 2 As shown, based on the above embodiments, in order to solve the problem of adhesive residue when bonding lubricating columns, the present invention also provides a scraping unit 400.

[0058] According to the appendix Figure 2 and attached Figure 8As shown, the base 120 has an annular groove inside, and the annular groove is connected to the inside of the through-hole. A scraping unit 400 is provided inside the through-hole. The scraping unit 400 is used to remove the adhesive residue attached to the outer surface of the mandrel 160.

[0059] In one embodiment, according to the appendix Figure 8 and attached Figure 9 As shown, the scraping unit 400 includes an annular scraper 410 installed in the through-hole. The inner diameter of the annular scraper 410 is adapted to the outer diameter of the mandrel 160. When the mandrel 160 passes through the annular scraper 410, the annular scraper 410 can scrape off the adhesive residue on the surface of the mandrel 160.

[0060] The scraping unit 400 also includes a collection port 420 formed along the circumference of the opening, which is connected to the interior of the annular inclined groove for collecting the scraped adhesive residue. The base 120 has several chip discharge ports 430, which are also connected to the interior of the annular inclined groove for discharging the collected adhesive residue outside the device for easy cleaning. The scraping unit 400 effectively prevents adhesive residue from accumulating on the surface of the mandrel 160, ensuring the cleanliness of the mandrel 160 and improving processing quality and efficiency.

[0061] Through the above-mentioned technical solution, this invention can not only effectively remove the debris generated during the lubrication post embedding process of the self-lubricating bearing 140, but also promptly clean the adhesive residue on the surface of the mandrel 160, significantly improving the processing quality and efficiency, reducing maintenance costs, and showing good prospects for industrial application.

[0062] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
