Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes an assembled rolling bearing assembly for a brake shoe roller and its assembly equipment.

[0023] Embodiment 1, in a typical implementation manner of the present application, as Figure 2 shown, an assembled rolling bearing assembly for a brake shoe roller and its assembly equipment, wherein the rolling bearing assembly includes a roller 101 and a bushing 102. The roller 101 is of a ring structure, the bushing 102 is of a ring structure, the size of the bushing 102 is adapted to the inner ring size of the roller 101, the bushing 102 is clamped in the inner ring of the roller 101, a plurality of through holes are provided on the bushing 102, the bushing 102 is in sliding fit with the roller 101, and the rolling bearing assembly is processed using the assembly equipment during assembly.

[0024] Specifically, the bushing 102 is pressed into the roller 101 by an assembly device to form a rolling bearing assembly, which can also be called a roller assembly.

[0025] Embodiment 2 is as follows. Figure 1 As shown, the difference from the above embodiment is that the assembly device includes a machine body 1, an assembly mechanism 2 arranged on the machine body 1, and an auxiliary mechanism 3 arranged on the machine body 1. The assembly mechanism 2 includes a hydraulic rod 22 and an assembly table 26. The hydraulic rod 22 is arranged on the machine body 1, and the assembly table 26 is arranged on the machine body 1. The assembly table 26 is located directly below the hydraulic rod 22. The extending rod of the hydraulic rod 22 is used to press and assemble the rolling bearing assembly on the assembly table 26. The auxiliary mechanism 3 includes a conveying component 3001 and a turntable 32. The turntable 32 is arranged on the machine body 1. The turntable 32 is adjacent to the assembly table 26. The conveying component 3001 is arranged on the turntable 32. The conveying component 3001 conveys the roller 101 and the bushing 102 to the assembly table 26.

[0026] When using the present invention: When assembling the rolling bearing assembly, start the turntable 32. The turntable 32 rotates to drive the conveying component 3001 to rotate. Use the conveying component 3001 to convey the bushing 102 and the roller 101 onto the assembly table 26. After the conveying component 3001 places the roller 101 on the assembly table 26, then place the bushing 102 on the roller 101. Then start the hydraulic rod 22. The hydraulic rod 22 presses the bushing 102 into the roller 101 to assemble the rolling bearing assembly. After the assembly is completed, the conveying component 3001 continues to convey the assembled rolling bearing assembly to move the assembled rolling bearing assembly out. At the same time, the conveying component 3001 synchronously places the next set of bushing 102 and roller 101 in position on the assembly table 26, thus replacing the cumbersome process that workers need to place the raw materials separately each time before operating the assembly device for assembly. It enables the single-column hydraulic press to be converted from the original worker-assisted production to automated production, greatly improving the working efficiency of the assembly device. And because the single-column hydraulic press is cheaper than other automated assembly devices, the assembly device reduces the operating cost on the basis of improving production efficiency and improves the applicability of the device.

[0027] Embodiment 3 is as follows. Figure 3As shown, the difference from the above embodiment is that the assembly mechanism 2 further includes a bracket 21. The bracket 21 is fixedly installed on the body 1. The top of the bracket 21 is fixedly installed with a hydraulic rod 22. The hydraulic rod 22 penetrates the bracket 21. The extension rod of the hydraulic rod 22 faces downward. A limiting rail 23 is fixedly installed on the bracket 21. The height of the limiting rail 23 is adapted to the telescopic range of the extension rod of the hydraulic rod 22. A positioning connecting rod 24 is arranged between the limiting rail 23 and the extension rod of the hydraulic rod 22. One end of the positioning connecting rod 24 is fixedly connected to the extension rod of the hydraulic rod 22, and the other end of the positioning connecting rod 24 is slidably matched with the limiting rail 23.

[0028] Furthermore, the track limiting length of the limiting rail 23 is the same as the telescopic range of the extension rod of the hydraulic rod 22. Sensors, such as touch sensors, are arranged at the top and bottom of the limiting rail 23. The sensors are signal-connected to the hydraulic rod 22. When the positioning connecting rod 24 moves on the limiting rail 23, the positioning connecting rod 24 touches the sensor to trigger signal control, so that the extension rod of the hydraulic rod 22 extends or contracts.

[0029] Further, a sliding rod 25 is arranged on the bracket 21. The sliding rod 25 penetrates the bracket 21. The sliding rod 25 is slidably matched with the bracket 21. The bottom end of the sliding rod 25 is fixedly connected to the positioning connecting rod 24. An assembly table 26 is fixedly installed on the body 1. An installation seat is arranged on the assembly table 26. The extension rod of the hydraulic rod 22 is adapted to the installation seat on the assembly table 26. The rolling bearing assembly is placed on the installation seat of the assembly table 26 for assembly processing. A controller 27 is fixedly installed on one side of the bracket 21. The controller 27 is used to control the operation of the assembly equipment.

[0030] Among them, during assembly, when the roller 101 is placed on the assembly table 26 and the bushing 102 is placed on the roller 101, the hydraulic rod 22 on the bracket 21 is started. The hydraulic rod 22 extends its extension rod. The extension rod of the hydraulic rod 22 presses the bushing 102 into the roller 101. At the same time, the movement of the extension rod of the hydraulic rod 22 drives the positioning connecting rod 24 to move. The positioning connecting rod 24 drives the sliding rod 25 to move, so that the mutual restriction between the sliding rod 25 and the bracket 21 restricts the stable movement of the positioning connecting rod 24. The positioning connecting rod 24 moves on the limiting rail 23. When the positioning connecting rod 24 moves to the bottom end of the limiting rail 23, the hydraulic rod 22 completes the assembly process of the roller 101 and the bushing 102, and then the hydraulic rod 22 resets.

[0031] Embodiment 4, as Figures 5 - 8As shown, the difference from the above embodiment is that the auxiliary mechanism 3 further includes a stepper motor 31. The stepper motor 31 is fixedly installed on the body 1. The stepper motor 31 is adjacent to the assembly table 26. A turntable 32 is fixedly installed on the shaft of the stepper motor 31.

One end of the first connecting member 37 is rotatably engaged with the first moving member 36. The other end of the first connecting member 37 is movably connected to the first ring frame 34. First cylinders 38 are fixedly installed on both sides of each first ring frame 34. The first cylinders 38 all penetrate through the wall surface of the first ring frame 34. A first clamping member 39 is fixedly installed on the extension rod of the first cylinder 38. The first clamping member 39 is located in the inner ring of the first ring frame 34.

[0033] Specifically, the first connecting member 37 is slidably connected to the first ring frame 34 and is rotatably engaged with the first ring frame 34, so that when the first ring frame 34 rotates, the distance between the first ring frame 34 and the first rail frame 35 is adapted by the first connecting member 37.

[0034] Among them, when conveying the conveying roller 101, the roller 101 falls into the first ring frame 34. The first cylinder 38 is started. The first cylinder 38 drives the first clamping member 39 to move, so that the first clamping member 39 clamps and fixes the roller 101 in the first ring frame 34. Then the stepper motor 31 is started. The stepper motor 31 drives the turntable 32 to rotate. The turntable 32 drives the first telescopic frame 33 to rotate. The first telescopic frame 33 drives the first ring frame 34 to rotate. The first ring frame 34 drives the first cylinder 38 to rotate. The first cylinder 38 drives the first clamping member 39 to rotate, so that the first clamping member 39 drives the roller 101 to move. At the same time, the first ring frame 34 drives the first connecting member 37 to move. The first connecting member 37 drives the first moving member 36 to move, so that the first moving member 36 moves on the first rail frame 35, so that the first telescopic frame 33 adapts to the shape of the first rail frame 35 for telescoping. After the first ring frame 34 moves above the assembly table 26, the turntable 32 stops rotating. The first clamping member 39 releases the clamping and fixing, and the roller 101 falls onto the assembly table 26.

[0035] Further, a plurality of second telescopic frames 310 are fixedly installed on the turntable 32. The second telescopic frames 310 are evenly distributed in a circular shape. The second telescopic frames 310 are of a multi-stage telescopic structure. Each of the second telescopic frames 310 is located above each of the first telescopic frames 33. The first telescopic frames 33 and the second telescopic frames 310 are distributed corresponding to each other vertically. Second ring frames 311 are fixedly installed on the extension rods of the second telescopic frames 310.

[0036] Further, a second rail frame 312 is fixedly installed on the machine body 1. The second rail frame 312 is of an annular structure. The second ring frames 311 are all located in the inner ring of the second rail frame 312. One end of the second rail frame 312 covers directly above the assembly table 26. The second rail frame 312 is located above the first rail frame 35. The other end of the second rail frame 312 is closer to the turntable 32 than the other end of the first rail frame 35. A plurality of second moving members 313 are slidably engaged with the second rail frame 312. Each of the second moving members 313 corresponds to each of the second ring frames 311. Second connecting members 314 are provided between the second moving members 313 and the second ring frames 311.

Second clamping members 316 are fixedly installed on the extension rods of the second air cylinders 315. The second clamping members 316 are located in the inner ring of the second ring frames 311.

[0037] Specifically, the second connecting member 314 is slidably connected to the second ring frame 311 and is rotatably engaged with the second ring frame 311. When the second ring frame 311 rotates, the distance between the second ring frame 311 and the second rail frame 312 is adapted by means of the second connecting member 314.

[0038] Further, the conveying assembly 3001 includes a first clamping member 39 and a second clamping member 316.

[0039] Among them, when transporting the bushing 102, the bushing 102 falls into the second ring frame 311. The second cylinder 315 is started, and the second cylinder 315 drives the second clamping member 316 to move, so that the second clamping member 316 clamps and fixes the bushing 102 in the second ring frame 311. Then, the turntable 32 is used to drive the second telescopic frame 310 to rotate. The second telescopic frame 310 drives the second ring frame 311 to rotate. The second ring frame 311 drives the second cylinder 315 to rotate. The second cylinder 315 drives the second clamping member 316 to rotate, so that the second clamping member 316 drives the bushing 102 to move. At the same time, the second ring frame 311 drives the second connecting member 314 to move. The second connecting member 314 drives the second moving member 313 to move, so that the second moving member 313 moves on the second rail frame 312, so that the second telescopic frame 310 expands and contracts to adapt to the shape of the second rail frame 312. After the second ring frame 311 moves above the assembly table 26, the turntable 32 stops rotating. The second clamping member 316 releases the clamping and fixing, and the bushing 102 falls onto the roller 101.

[0040] Further, a blanking slide plate 317 is fixedly installed on the machine body 1. The blanking slide plate 317 is located below the moving track of the first ring frame 34. The blanking slide plate 317 is used to receive the assembled rolling bearing assembly.

[0041] Among them, after the assembly is completed, the first clamping member 39 clamps and fixes the assembled rolling bearing assembly. The first clamping member 39 drives the rolling bearing assembly to move above the blanking slide plate 317. The first clamping member 39 then releases the clamping, and the assembled rolling bearing assembly falls onto the blanking slide plate 317 for blanking.

[0042] Further, a plurality of loading racks 318 are fixedly installed on the machine body 1.

The distance between the other side of the feeding dial plate 320 and the loading rack 318 is adapted to the size of the bushing 102. Support plates 321 are fixedly installed below the other end of the first rail frame 35 and the other end of the second rail frame 312. Each support plate 321 is located directly below each loading rack 318.

[0043] Further, the bushing 102 is placed on the loading rack 318 close to the turntable 32 for standby. The roller 101 is placed on the other loading rack 318 for standby. The roller 101 slides on the loading rack 318 by gravity. Similarly, the bushing 102 slides on the loading rack 318 by gravity, so as to automatically supplement the raw materials in the assembly of the rolling bearing assembly.

[0044] Furthermore, the rollers 101 on the loading rack 318 can be replenished manually by workers at regular intervals, or can be replenished automatically by a conveying system such as a conveyor belt. Similarly, the bushings 102 on the loading rack 318 can be replenished manually by workers at regular intervals, or can be replenished automatically by a conveying system such as a conveyor belt. The present invention does not specifically limit the method of replenishing the raw materials required for the rolling bearing assembly.

[0045] The roller 101 and the bushing 102 are arranged and placed on the loading rack 318. When the roller 101 needs to be supplemented, the rotating shaft cylinder 319 is started, and the rotating shaft cylinder 319 drives the feeding paddle 320 to rotate, so that the feeding paddle 320 pokes a roller 101 to fall from the loading rack 318, so that the roller 101 falls on the supporting plate 321 (when the roller 101 needs to be supplemented, the first ring frame 34 is moved to the top of the supporting plate 321, that is, when the roller 101 falls on the supporting plate 321, the roller 101 will also fall into the inner ring of the first ring frame 34), and the roller 101 is clamped by the first clamping member 39. 101 is clamped and fixed, thereby completing the replenishment; similarly, when the bushing 102 needs to be replenished, the shaft cylinder 319 drives the feeding paddle 320 to rotate, so that the feeding paddle 320 pushes a bushing 102 to fall from the loading rack 318, so that the bushing 102 falls on the support plate 321 (when the bushing 102 needs to be replenished, the second ring frame 311 moves to the top of the support plate 321, that is, when the bushing 102 falls on the support plate 321, the bushing 102 will also fall into the inner ring of the second ring frame 311), and the bushing 102 is clamped and fixed by the second clamping member 316, thereby completing the replenishment.

The hydraulic rod 22 presses the bushing 102 into the roller 101 to assemble the rolling bearing assembly. After the assembly is completed, the conveying assembly 3001 continues to transport the assembled rolling bearing assembly to The assembled rolling bearing assembly is removed, and the conveying assembly 3001 synchronously places the next set of bushings 102 and rollers 101 on the assembly table 26 according to the position, thereby replacing the tediousness of workers placing the raw materials one by one each time before running the assembly equipment for assembly, so that the single-column hydraulic press is converted from the original worker-coordinated production to automated production, which greatly improves the working efficiency of the assembly equipment. In addition, since the single-column hydraulic press is cheaper than other automated assembly equipment, the assembly equipment reduces the operating cost on the basis of improving production efficiency, and improves the applicability of the equipment; Among them, when conveying the roller 101, the roller 101 drops into the first ring frame 34. Start the first cylinder 38, and the first cylinder 38 drives the first clamping member 39 to move, so that the first clamping member 39 clamps and fixes the roller 101 in the first ring frame 34. Then start the stepping motor 31, the stepping motor 31 drives the turntable 32 to rotate, the turntable 32 drives the first telescopic frame 33 to rotate, the first telescopic frame 33 drives the first ring frame 34 to rotate, the first ring frame 34 drives the first cylinder 38 to rotate, and the first cylinder 38 drives the first clamping member 39 to rotate, so that the first clamping member 39 drives the roller 101 to move. At the same time, the first ring frame 34 drives the first connecting member 37 to move, and the first connecting member 37 drives the first moving member 36 to move, so that the first moving member 36 moves on the first rail frame 35, so that the first telescopic frame 33 expands and contracts to adapt to the shape of the first rail frame 35. After the first ring frame 34 moves above the assembly table 26, the turntable 32 stops rotating, the first clamping member 39 releases the clamping and fixing, and the roller 101 falls onto the assembly table 26; When conveying the bushing 102, the bushing 102 drops into the second ring frame 311. Start the second cylinder 315, and the second cylinder 315 drives the second clamping member 316 to move, so that the second clamping member 316 clamps and fixes the bushing 102 in the second ring frame 311. Then use the turntable 32 to drive the second telescopic frame 310 to rotate, the second telescopic frame 310 drives the second ring frame 311 to rotate, the second ring frame 311 drives the second cylinder 315 to rotate, and the second cylinder 315 drives the second clamping member 316 to rotate, so that the second clamping member 316 drives the bushing 102 to move. At the same time, the second ring frame 311 drives the second connecting member 314 to move, and the second connecting member 314 drives the second moving member 313 to move, so that the second moving member 313 moves on the second rail frame 312, so that the second telescopic frame 310 expands and contracts to adapt to the shape of the second rail frame 312. After the second ring frame 311 moves above the assembly table 26, the turntable 32 stops rotating, the second clamping member 316 releases the clamping and fixing, and the bushing 102 falls onto the roller 101; When assembling, after the roller 101 is placed on the assembly table 26 and the bushing 102 is placed on the roller 101, start the hydraulic rod 22 on the bracket 21, and the hydraulic rod 22 extends the rod. The rod of the hydraulic rod 22 presses the bushing 102 into the roller 101. At the same time, the movement of the rod of the hydraulic rod 22 drives the positioning link 24 to move, and the positioning link 24 drives the slide bar 25 to move, so that the mutual restriction between the slide bar 25 and the bracket 21 restricts the stable movement of the positioning link 24. The positioning link 24 moves on the limit rail 23. When the positioning link 24 moves to the bottom end of the limit rail 23, the hydraulic rod 22 completes the assembly process of the roller 101 and the bushing 102, and then the hydraulic rod 22 resets; After the assembly is completed, the first clamping member 39 clamps and fixes the assembled rolling bearing assembly. The first clamping member 39 drives the rolling bearing assembly to move above the blanking slide plate 317, and then the first clamping member 39 releases the clamping, and the assembled rolling bearing assembly falls onto the blanking slide plate 317 for blanking; When replenishing raw materials, the rollers 101 and the bushings 102 are arranged on the loading rack 318. When it is necessary to replenish the rollers 101, the rotating shaft cylinder 319 is started. The rotating shaft cylinder 319 drives the feeding dial 320 to rotate, so that the feeding dial 320 toggles a roller 101 to fall from the loading rack 318, and the roller 101 falls onto the support plate 321 (where when it is necessary to replenish the rollers 101, the first ring frame 34 is moved above the support plate 321, that is, when the roller 101 falls onto the support plate 321, the roller 101 also falls into the inner ring of the first ring frame 34). The first clamping member 39 is used to clamp and fix the roller 101, thereby completing the replenishment; similarly, when it is necessary to replenish the bushings 102, the rotating shaft cylinder 319 drives the feeding dial 320 to rotate, so that the feeding dial 320 toggles a bushing 102 to fall from the loading rack 318, and the bushing 102 falls onto the support plate 321 (where when it is necessary to replenish the bushings 102, the second ring frame 311 is moved above the support plate 321, that is, when the bushing 102 falls onto the support plate 321, the bushing 102 also falls into the inner ring of the second ring frame 311). The second clamping member 316 is used to clamp and fix the bushing 102, thereby completing the replenishment.
