Description

Technical Field

[0001] The present invention relates to the technical field of tilting pad bearing processing, and in particular to a processing device for processing the inner back surface of a tilting pad in a machining center. Background Art

[0002] A tilting pad bearing is a swinging pad bearing, typically composed of three to five or more curved pads that can tilt freely on a pivot point. This is why it's also called a live-support multi-pad bearing. Because the pads can swing freely with speed, load, and bearing temperature, they form multiple oil wedges around the journal, with the oil film pressure always pointing toward the center, resulting in high stability.

[0003] Patent document CN2020231958130 discloses a tilting pad supported sliding bearing that is easy to assemble, which includes a bearing seat, a cover plate and a tilting guide pad.

Several groups of encapsulation threaded grooves 75 are provided on the upper and lower surfaces of the shell 7.

[0056] The conveyor belt 11 drives the carrying component 21 to move to the position directly below the unloading mechanism 3 and then stops. The unloading mechanism 3 automatically releases the two shells 7 onto the carrying component 21. The positioning component 22 locates the positions of the two shells 7 and pre-assembles the two shells 7 to form a ring. The flipping component 23 drives the two shells 7 assembled into a ring to flip. The internal installation mechanism 4 installs several groups of tiles 8 on the inner walls of the two shells 7. The side installation mechanism 5 installs the cover plate 9 on both surfaces of the shell 7. Finally, the fastening mechanism 6 assembles the two shells 7 again.

[0057] In this embodiment, by cooperating with the carrying mechanism 2 and the internal installation mechanism 4, on the one hand, the tilting pad bearing can be assembled automatically, which saves time and labor, improves the assembly efficiency of the tilting pad bearing, and can be mass-produced to increase the production efficiency of the enterprise; on the other hand, the positioning effect is better, and the assembly can be carried out at the specified position with high assembly accuracy, which improves the assembly effect of the tilting pad bearing and can reduce wear during the assembly process, thereby ensuring the high performance of the tilting pad bearing, and the assembled tilting pad bearing is of high quality, which reduces the product loss rate.

[0058] In detail, first, the conveyor belt 11 drives the carrying component 21 to move to the position directly below the unloading mechanism 3 and then stops operating. The unloading mechanism 3 automatically releases the two shells 7 onto the carrying component 21. The positioning component 22 locates the positions of the two shells 7 and pre-assembles the two shells 7 to form a ring. The flipping component 23 drives the two shells 7 assembled into a ring to flip 90 degrees. Then, the conveyor belt 11 drives the carrying component 21 to move to the position of the internal installation mechanism 4 and then stops operating. The feeding component 42 sequentially absorbs several groups of tile plates 8 and sends several groups of tile plates 8 to the specified positions in the two shells 7 at the same time, and drives several groups of tile plates 8 to spread outward to the specified positions on the inner walls of the two shells 7. The internal installation component 43 sequentially installs several groups of tile plates 8 at the specified positions on the inner walls of the two shells 7 through bolts. Then, the conveyor belt 11 drives the bearing component 21 to move to the position of the side-mounted mechanism 5 and then stops operating. The assembly component 52 sucks the cover plate 9. The positioning component 22 drives the two shells 7 apart through the first vacuum suction cup 231, and the assembly component 52 sends the cover plate 9 to the surface of the two shells 7. The positioning component 22 drives the two shells 7 to form a ring again. The assembly component 52 installs the cover plate 9 at the specified position on the surface of the two shells 7. Finally, the conveyor belt 11 drives the bearing component 21 to move to the position of the fastening mechanism 6 and then stops operating. The flipping component 23 drives the two shells 7 to flip and reset on the bearing component 21. The bearing component 21 then drives the two shells 7 to rotate horizontally 90 degrees. The fastening mechanism 6 assembles and fastens the two shells 7 again through bolts to complete the assembly of the tilting pad bearing.

[0060] The positioning assembly 22 includes two sets of first hydraulic components 221 respectively provided on the side walls of the U-shaped bottom frame 211, a U-shaped connecting frame 222 provided at the output end of the first hydraulic component 221, a second motor 223 provided on the U-shaped connecting frame 222, a flip frame 224 provided on the output shaft of the second motor 223, a clamp 225 provided on the flip frame 224, and two sets of positioning rods 226 respectively provided at the ends of the clamp 225 and slidably matched with the assembly threaded holes 71 of the housing 7.

[0061] The flip assembly 23 includes two sets of first vacuum suction cups 231 provided on the flip frame 224, a first rack 232 provided on the U-shaped connecting frame 222 and used to drive the first gear 214, a strip plate 233 provided at the end of the first rack 232, and a second rack 234 provided at the end of the strip plate 233 and used to drive the first gear 214.

[0062] The unloading mechanism 3 includes a barrel 31 disposed on the conveying frame 1 and an automatic injector 32 disposed at a lower end of the barrel 31 .

[0063] It should be noted that the structure and function of the automatic filling machine 32 are both existing technologies and will not be described in detail. It can realize the automatic unloading of the shell 7.

[0064] In this embodiment, through the support assembly 21, on the one hand, it can drive the receiving plate 217 to automatically rise and fall, so that the receiving plate 217 can smoothly and accurately receive the two shells 7, and can position the two shells 7 to dock into a ring, thereby realizing the pre-assembly of the two shells 7, thereby positioning the installation position of the shoe plate 8 and the cover plate 9 on the shell 7; on the other hand, it can drive the two pre-assembled shells 7 to flip 90 degrees, so that the shoe plate 8 can enter and approach the inner wall of the shell 7, and it can also facilitate the cover plate 9 to be installed on both surfaces of the shell 7 at the same time, thereby shortening the assembly time of the tilting pad bearing.

[0065] In detail, the conveyor belt 11 drives the bearing assembly 21 to move to the position directly below the unloading mechanism 3 and then stops. The first hydraulic component 221 drives the U-shaped connecting frame 222 to move to both sides with the clamp 225, so that the U-shaped connecting frame 222 moves horizontally with the first rack 232. The first rack 232 drives the screw rod 213 to rotate through the first gear 214. The screw rod 213 drives the L-shaped support rod 216 to move with the receiving plate 217 through the lifting block 215, so that the receiving plate 217 rises to the position of the automatic injection machine 32, and the automatic injection machine 32 releases the two shells 7. After being placed flat in the elliptical receiving groove on the receiving plate 217, the first hydraulic component 221 drives the U-shaped connecting frame 222 to move the two clamps 225 to the middle position, so that the first rack 232 drives the screw rod 213 to rotate in the opposite direction through the first gear 214, so that the receiving plate 217 and the two shells 7 are lowered to the original position. Then, the first hydraulic component 221 continues to drive the two clamps 225 to move to the middle position, and the strip plate 233 passes the first gear 214. The receiving plate 217 will not be raised or lowered. The positioning rods 226 of the clamps 225 are inserted into the receiving plate 217 at the same time. After the two shells 7 are assembled with the threaded holes 71, the positioning rod 226 supports and positions the two shells 7. Then, the first hydraulic component 221 continues to drive the two clamps 225 to move to the middle position. The two clamps 225 drive the two shells 7 to dock into a ring. At the same time, the second rack 234 drives the first gear 214 to rotate with the screw rod 213, so that the screw rod 213 drives the receiving plate 217 to descend through the lifting block 215, so that the receiving plate 217 avoids the flipping work of the two shells 7. Then, the second motor 223 drives the flip frame 22 The two shells 7 are flipped 90 degrees by the clamping hoop 225. After the tile plate 8 and the cover plate 9 are installed at the designated positions of the shell 7, the clamping hoop 225 flips the two shells 7 in the opposite direction 90 degrees. Then, the receiving plate 217 rises and resets to catch the two shells 7 again. The positioning rod 226 of the clamping hoop 225 is separated from the two shells 7 and reset. Finally, the first motor 219 drives the disc 218 to rotate the two shells 7 horizontally 90 degrees, adjusting the directions of the assembly threaded holes 71 of the two shells 7 so that the fastening mechanism 6 can finally assemble and fix the two shells 7, completing the assembly work.

[0066] Further, if Figure 1-Figure 7 and Figures 9-11 As shown, the internal installation mechanism 4 includes a discharge assembly 41 provided on the conveying frame 1 and containing the tile plate 8, a feeding assembly 42 provided on the discharge assembly 41 and used to feed the tile plate 8 to the inner wall of the shell 7, and an internal installation assembly 43 provided on the clamp 225 and used to fix the tile plate 8 to the inner wall of the shell 7;

[0067] The unloading assembly 41 includes a vertical block 411 provided on the conveying frame 1, a circular hole 412 provided on the vertical block 411 and having the same outer radius as the tile plate 8, a material cavity 413 provided at the bottom of the circular hole 412 and containing the tile plate 8, a first elastic member 414 provided at the bottom of the material cavity 413, a first push plate 415 provided at the end of the first elastic member 414 and used to support the tile plate 8, and an L-shaped ear plate 416 provided at the bottom of the circular hole 412 and having the same inner radius as the tile plate 8, wherein the distance between the L-shaped ear plate 416 and the bottom of the circular hole 412 is equal to the thickness of the tile plate 8;

[0068] The feeding assembly 42 includes a second hydraulic component 421 provided on the vertical block 411 through an L-shaped support plate, a stepper motor provided on the output shaft of the second hydraulic component 421, a hollow tube 422 provided at the output end of the stepper motor, a push rod 423 slidably provided inside the hollow tube 422, a second elastic component 424 provided between the end of the push rod 423 and the inner end of the hollow tube 422, a plurality of sets of sleeve rods 425 provided on the push rod 423 along the circumferential direction, a plurality of sleeve rods 425 slidably provided on the hollow tube 422, and a plurality of sleeve rods 425 provided on the hollow tube 422.

[0069] It is worth mentioning that since the distance from the L-shaped ear plate 416 to the bottom of the circular hole 412 is equal to the thickness of the tile plate 8, that is, a tile plate 8 can be accommodated between the L-shaped ear plate 416 and the inner wall of the circular hole 412, the second vacuum suction cup 427 is exactly located at the position of the L-shaped ear plate 416, which makes it convenient for the second vacuum suction cup 427 to absorb the tile plate 8, and the stepper motor drives the hollow tube 422 to intermittently rotate the specified angle, so that each second vacuum suction cup 427 absorbs a tile plate 8 in turn.

[0070] It should be noted that the positioning pin 4291 on the hollow tube 422 can only pass through the strip gap 4292 on the vertical block 411, that is, the position of each second vacuum suction cup 427 is located, and then the distribution position of the tile plate 8 is located, so that the internal thread groove 81 of the tile plate 8 can correspond to the position of the mounting hole 74 of the shell 7.

[0071] It should also be noted that the first vacuum suction cup 231 and the second vacuum suction cup 427 are respectively connected to an existing external vacuum generator.

[0072] In this embodiment, by cooperating with the set discharge component 41 and the feeding component 42, on the one hand, several groups of tiles 8 can be automatically sucked in sequence, so that the tiles 8 can be installed on the inner wall of the shell 7 at one time, thereby improving the installation efficiency of the tiles 8; on the other hand, the tiles 8 can be delivered to the designated position of the inner wall of the shell 7, which facilitates the installation of the tiles 8 with high precision, and in the process of conveying the tiles 8, the tiles 8 are prevented from contacting and rubbing with the equipment, thereby reducing the wear of the tiles 8.

[0073] In detail, the conveyor belt 11 drives the carrying component 21 to move to the position of the internal mechanism 4 and then stops, the second vacuum suction cup 427 sucks the tile 8 at the L-shaped ear plate 416, and the stepper motor drives the hollow tube 422 to intermittently rotate a specified angle, so that the second vacuum suction cup 427 sucks the tile 8 at the L-shaped ear plate 416 and moves along the inner wall of the circular hole 412, and the first push plate 415 in the material cavity 413 is driven by the first elastic member 414 to rise to the L-shaped ear plate 416 in turn with the tile 8, and the remaining second vacuum suction cups 427 suck the tile 8 at the L-shaped ear plate 416 in turn, and then the stepper motor continues to drive the hollow tube 422 to rotate a certain angle, so that the positioning pin 4291 on the hollow tube 422 is aligned with the gap on the vertical block 411. Corresponding to the position 4292, the second hydraulic component 421 drives the hollow tube 422 to move horizontally with the tile 8 to the inside of the two shells 7 through the push rod 423, the sleeve rod 425, the sleeve 426, and the second vacuum suction cup 427 until the end of the push rod 423 rests on the baffle 429, so that the tile 8 will no longer move forward. Then, the second hydraulic component 421 continues to drive the hollow tube 422 to move forward, so that the push rod 423 moves relatively inside the hollow tube 422 and compresses the second elastic component 424, so that the inclined rod 428 drives the sleeve 426 and the sleeve rod 425 to slide relative to each other, so that the sleeve 426 drives the tile 8 to diffuse outward to the inner walls of the two shells 7, so that several groups of tile 8 are simultaneously attached to the specified positions on the inner wall of the shell 7.

[0074] Further, if Figure 4-Figure 7As shown, the internal assembly 43 includes a slide 431 opened on the outer wall of the clamp 225, an arc-shaped plate 432 slidably arranged inside the slide 431, teeth opened on the top of the arc-shaped plate 432, a hollow box 433 set on the outer wall of the arc-shaped plate 432 and equipped with bolts, a third elastic member 434 set inside the hollow box 433, a second push plate 435 set at the end of the third elastic member 434, an outlet hole 436 opened on the side wall of the hollow box 433 and passing through the arc-shaped plate 432, several groups of through holes 437 opened on the clamp 225 for the bolts to pass through, and a through hole 438 set on the hollow box 433.

At the same time, the third motor 439 drives the first tightening rod 4392 to rotate, so that the first tightening rod 4392 pushes a bolt in the hollow box 433 from the exit hole 436 to the through hole 437 on the clamp 225, and the bolt then passes through the through hole 437 on the clamp 225 into the mounting hole 74 of the shell 7 and the internal threaded groove 81 of the tile 8, thereby installing the tile 8 on the inner wall of the shell 7.

Then, the two clamps 225 drive the two shells 7 to separate slightly through the first vacuum suction cup 231, so that the cover plate 9 falls on the surface of the shell 7 through the gap. The fourth hydraulic component 521 continues to drive the feeding column 522 to move, so that the feeding column 522 delivers the cover plate 9 to the surface of the shell 7.
