Abstract

The present invention relates to the technical field of brake shoe roller assembly, and discloses a rolling bearing assembly of an assembled brake shoe roller and an assembly device thereof. The turntable rotates to drive the conveying assembly to rotate, and the conveying assembly conveys the bushing and the roller to the assembly table. After the conveying assembly places the roller on the assembly table, the bushing is placed on the roller. The hydraulic rod presses the bushing into the roller to assemble the rolling bearing assembly. The conveying assembly then continues to transport the assembled rolling bearing assembly to remove the assembled rolling bearing assembly, thereby replacing the tedious process of workers placing the raw materials one by one before running the assembly equipment for assembly. 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. 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.

Description

Technical Field

[0001] The present invention relates to the technical field of brake shoe roller assembly, in particular to a rolling bearing assembly of an assembled brake shoe roller and an assembly device thereof. Background Art

[0002] The brake shoe roller, along with the brake shoe support pin, camshaft, return spring, adjusting arm, tension spring and other components, forms a drum brake. The brake shoe roller requires assembly equipment for processing during assembly.

[0003] In existing assembly equipment, such as Chinese patent application CN112517716A, round rods can be quickly formed by setting up a cold pressing die set and a cold pressing mechanism; through the setting of this equipment, automatic loading, processing and unloading can be carried out, and through this process, most of the surface of the product is directly formed after extrusion, so the surface processing amount is small, the processing cost is reduced, and the production efficiency is improved.

[0004] However, there are still the following problems: In order to control processing costs, the use of a single-column hydraulic press in conjunction with workers for assembly and processing is currently a more cost-effective approach.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a rolling bearing assembly of an assembled brake shoe roller and an assembly device thereof.

[0032] Example 1, a typical embodiment of the present application, as Figure 2As shown, a rolling bearing assembly of an assembled brake shoe roller and its assembly equipment, wherein the rolling bearing assembly includes a roller 101 and a bushing 102, the roller 101 is an annular structure, the bushing 102 is an annular structure, the size of the bushing 102 is adapted to the size of the inner ring of the roller 101, the bushing 102 is engaged in the inner ring of the roller 101, a plurality of through holes are opened on the bushing 102, the bushing 102 and the roller 101 are slidably matched, and the rolling bearing assembly is processed using assembly equipment during assembly.

[0033] Specifically, the bushing 102 is pressed into the roller 101 by an assembly device to form a rolling bearing assembly, which may also be called a roller assembly.

[0034] Example 2, as Figure 1 As shown, the difference from the above embodiment is that the assembly equipment includes a machine body 1, an assembly mechanism 2 provided on the machine body 1, and an auxiliary mechanism 3 provided on the machine body 1. The assembly mechanism 2 includes a hydraulic rod 22 and an assembly table 26. The machine body 1 is provided with the hydraulic rod 22, and the machine body 1 is provided with the assembly table 26. The assembly table 26 is located directly below the hydraulic rod 22. The extension rod of the hydraulic rod 22 is used to press and assemble the rolling bearing assembly on the assembly table 26.

[0035] The auxiliary mechanism 3 includes a conveying component 3001 and a turntable 32 . The turntable 32 is provided on the machine body 1 and is adjacent to the assembly table 26 . The conveying component 3001 is provided on the turntable 32 . The conveying component 3001 conveys the roller 101 and the bushing 102 to the assembly table 26 .

[0036] When using the present invention:

[0037] When assembling the rolling bearing assembly, start the turntable 32, the turntable 32 rotates to drive the conveying assembly 3001 to rotate, and use the conveying assembly 3001 to convey the bushing 102 and the roller 101 to the assembly table 26. After the conveying assembly 3001 places the roller 101 on the assembly table 26, the bushing 102 is placed on the roller 101, and then the hydraulic rod 22 is started. 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 at the same time, the conveying assembly 3001 synchronously places the next set of bushings 102 and rollers 101 on the assembly table 26 according to their positions, thereby replacing the tedious process of workers placing the raw materials one by one each time before running the assembly equipment for assembly. The single-column hydraulic press is converted from the original worker-assisted production to automated production, which greatly improves the working efficiency of the assembly equipment. Since the single-column hydraulic press is cheaper than other automated assembly equipment, the assembly equipment reduces operating costs on the basis of improving production efficiency, thereby improving the applicability of the equipment.

[0038] Example 3, as Figure 3 As shown, the difference from the above embodiment is that the assembly mechanism 2 also includes a bracket 21, the bracket 21 is fixedly installed on the body 1, and a hydraulic rod 22 is fixedly installed on the top of the bracket 21. The hydraulic rod 22 passes through the bracket 21, and 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 link 24 is provided between the limiting rail 23 and the extension rod of the hydraulic rod 22. One end of the positioning link 24 is fixedly connected to the extension rod of the hydraulic rod 22, and the other end of the positioning link 24 is slidably matched with the limiting rail 23.

[0039] Furthermore, the track limit length of the limit rail 23 is the same as the telescopic range of the extension rod of the hydraulic rod 22. Sensors, such as touch sensors, are set at the top and bottom ends of the limit rail 23. The sensors are connected to the signals of the hydraulic rod 22, so that when the positioning link 24 moves on the limit rail 23, the positioning link 24 touches the sensor to trigger the signal control, so that the extension rod of the hydraulic rod 22 is extended or retracted.

[0040] Furthermore, a slide rod 25 is provided on the bracket 21, and the slide rod 25 passes through the bracket 21. The slide rod 25 slides with the bracket 21, and the bottom end of the slide rod 25 is fixedly connected to the positioning link 24. An assembly table 26 is fixedly installed on the body 1, and a mounting seat is provided on the assembly table 26. The extension rod of the hydraulic rod 22 is adapted to the mounting seat of the assembly table 26, and the rolling bearing assembly is placed on the mounting seat of the assembly table 26 for assembly processing. A controller 27 is fixedly installed on one side of the bracket 21, and the controller 27 is used to control the operation of the assembly equipment.

[0041] Among them, during assembly, after 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, and the hydraulic rod 22 extends the rod. The extension of the hydraulic rod 22 presses the bushing 102 into the roller 101, and at the same time, the movement of the extension 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 limits the stable movement of the positioning link 24, and 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 the hydraulic rod 22 is then reset.

[0042] Example 4, as Figure 5-Figure 8As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a stepper motor 31, the stepper motor 31 is fixedly mounted on the body 1, the stepper motor 31 is adjacent to the assembly table 26, a turntable 32 is fixedly mounted on the axis of the stepper motor 31, the setting position of the turntable 32 is higher than the top of the assembly table 26, and a plurality of first telescopic frames 33 are fixedly mounted on the turntable 32. The first telescopic frames 33 are evenly distributed in a circle, the first telescopic frames 33 are a multi-stage telescopic structure, and the extension rods of the first telescopic frames 33 are fixedly mounted with first ring frames 34.

[0043] Furthermore, a first rail frame 35 is fixedly mounted on the machine body 1. The first rail frame 35 is an annular structure. The first ring frames 34 are all located in the inner ring of the first rail frame 35. One end of the first rail frame 35 covers the top of the assembly table 26. A plurality of first moving members 36 are slidably fitted on the first rail frame 35. Each first moving member 36 corresponds to each first ring frame 34. A first connecting member 37 is provided between the first moving member 36 and the first ring frame 34. One end of the first connecting member 37 is rotatably fitted with the first moving member 36, and the other end of the first connecting member 37 is movably connected to the first ring frame 34. First cylinders 38 are fixedly mounted on both sides of each first ring frame 34. The first cylinders 38 all penetrate the wall of the first ring frame 34. A first clamping member 39 is fixedly mounted 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.

[0044] Specifically, the first connecting member 37 is slidably connected to the first ring frame 34 and is rotationally matched with the first ring frame 34 , so that when the first ring frame 34 rotates, the first connecting member 37 is used to adapt the distance between the first ring frame 34 and the first rail frame 35 .

[0045] When the roller 101 is being conveyed, 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 the roller 101 in the first ring frame 34, and 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, and the first cylinder 38 drives the first telescopic frame 33 to rotate. The first clamping member 39 is rotated, 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 movable member 36 to move, so that the first movable 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 and is telescopic. After the first ring frame 34 moves to the top of the assembly table 26, the turntable 32 stops rotating, the first clamping member 39 releases the clamping fixation, and the roller 101 falls onto the assembly table 26.

[0046] Furthermore, a plurality of second telescopic frames 310 are fixedly mounted on the turntable 32. The second telescopic frames 310 are evenly distributed in a circular shape. The second telescopic frames 310 are multi-stage telescopic structures. Each second telescopic frame 310 is located above each first telescopic frame 33. The first telescopic frames 33 and the second telescopic frames 310 are correspondingly distributed up and down. A second ring frame 311 is fixedly mounted on the extension rod of the second telescopic frame 310.

[0047] Furthermore, a second rail 312 is fixedly mounted on the body 1. The second rail 312 is an annular structure. The second ring frames 311 are all located in the inner ring of the second rail 312. One end of the second rail 312 covers the top of the assembly table 26. The second rail 312 is located above the first rail 35. The other end of the second rail 312 is closer to the turntable 32 than the other end of the first rail 35. A plurality of second moving members 313 are slidably fitted on the second rail 312. Each second moving member 313 is relative to each second ring frame 311. A second connecting member 314 is provided between the second movable member 313 and the second ring frame 311. One end of the second connecting member 314 is rotatably engaged with the second movable member 313, and the other end of the second connecting member 314 is movably connected to the second ring frame 311. A second cylinder 315 is fixedly installed on both sides of each second ring frame 311. The second cylinder 315 passes through the wall of the second ring frame 311. A second clamping member 316 is fixedly installed on the extension rod of the second cylinder 315. The second clamping member 316 is located in the inner ring of the second ring frame 311.

[0048] Specifically, the second connecting member 314 is slidably connected to the second ring frame 311 and rotatably cooperates with the second ring frame 311 so that when the second ring frame 311 rotates, the second connecting member 314 adapts the distance between the second ring frame 311 and the second rail frame 312.

[0049] Furthermore, the conveying assembly 3001 includes a first clamping member 39 and a second clamping member 316 .

[0050] When the bushing 102 is transported, the bushing 102 falls into the second ring frame 311, and the second cylinder 315 is started. The second cylinder 315 drives the second clamping member 316 to move, so that the second clamping member 316 clamps 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, 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, and 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 adapts to the shape of the second rail frame 312 to be telescopic. After the second ring frame 311 moves to the top of the assembly table 26, the turntable 32 stops rotating, the second clamping member 316 releases the clamping fixation, and the bushing 102 falls onto the roller 101.

[0051] Furthermore, a blanking slide 317 is fixedly mounted on the machine body 1 and is located below the moving track of the first ring frame 34 . The blanking slide 317 is used to receive the assembled rolling bearing assembly.

[0052] Among them, after the assembly is completed, the first clamping member 39 clamps and fixes the assembled rolling bearing assembly, and the first clamping member 39 drives the rolling bearing assembly to move above the unloading slide 317. The first clamping member 39 then releases the clamping, and the assembled rolling bearing assembly falls onto the unloading slide 317 for unloading.

[0053] Furthermore, a plurality of loading racks 318 are fixedly installed on the machine body 1, and the loading racks 318 are respectively located above the other end of the first rail frame 35 and above the other end of the second rail frame 312. The loading racks 318 are fixedly installed with a rotating shaft cylinder 319, and a feeding plate 320 is fixedly installed on the axis of the rotating shaft cylinder 319. The distance between the feeding plate 320 and the loading rack 318 on one side is adapted to the size of the roller 101, and the distance between the feeding plate 320 and the loading rack 318 on the other side is adapted to the size of the bushing 102. A support plate 321 is fixedly installed below the other end of the first rail frame 35 and the other end of the second rail frame 312, and each support plate 321 is located directly below each loading rack 318.

[0054] Furthermore, a bushing 102 is placed on the loading rack 318 near the turntable 32 for standby use, and a roller 101 is placed on another loading rack 318 for standby use. Gravity is used to make the roller 101 slide on the loading rack 318, and similarly, gravity is used to make the bushing 102 slide on the loading rack 318, thereby automatically replenishing the raw materials in the assembly of the rolling bearing assembly.

[0055] Furthermore, the rollers 101 on the loading rack 318 can be replenished manually by workers at intervals, or can be replenished automatically using a conveying system such as a conveyor belt. Similarly, the bushings 102 on the loading rack 318 can be replenished manually by workers at intervals, or can be replenished automatically using 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.

[0056] The roller 101 and the bushing 102 are arranged and placed on the loading rack 318. When the roller 101 needs to be replenished, the shaft cylinder 319 is started, and the shaft cylinder 319 drives the feeding plate 320 to rotate, so that the feeding plate 320 drives a roller 101 to fall from the loading rack 318, so that the roller 101 falls on the support plate 321 (when the roller 101 needs to be replenished, the first ring frame 34 is moved to the top of the support plate 321, that is, when the roller 101 falls on the support plate 321, the roller 101 will also fall into the inner ring of the first ring frame 34). 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 paddles 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.

[0057] Working principle of the present invention:

[0058] When assembling the rolling bearing assembly, start the turntable 32, the turntable 32 rotates to drive the conveying assembly 3001 to rotate, and use the conveying assembly 3001 to convey the bushing 102 and the roller 101 to the assembly table 26. After the conveying assembly 3001 places the roller 101 on the assembly table 26, the bushing 102 is placed on the roller 101, and then the hydraulic rod 22 is started. 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 at the same time, the conveying assembly 3001 synchronously places the next set of bushings 102 and rollers 101 on the assembly table 26 according to their positions. This replaces the tedious process of workers placing the raw materials one by one before running the assembly equipment for assembly. The single-column hydraulic press is transformed from a worker-assisted production to an 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 operating costs while improving production efficiency, thereby improving the applicability of the equipment.

[0059] When the roller 101 is being conveyed, 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 the roller 101 in the first ring frame 34, and 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, and the first cylinder 38 drives the first telescopic frame 33 to rotate. The first clamping member 39 is rotated, 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 adapts to the shape of the first rail frame 35 and is telescopic. After the first ring frame 34 moves to the top of the assembly table 26, the turntable 32 stops rotating, the first clamping member 39 releases the clamping fixation, and the roller 101 falls onto the assembly table 26;

[0060] When the bushing 102 is being transported, the bushing 102 falls into the second ring frame 311, and the second cylinder 315 is started. 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. The turntable 32 is then 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, and the second cylinder 315 drives the second clamping member 316 to rotate. The second clamping member 316 drives the bushing 102 to move, and 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 adapts to the shape of the second rail frame 312 and is telescopic. 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 fixation, and the bushing 102 falls onto the roller 101;

[0061] During assembly, after 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, and the hydraulic rod 22 extends the 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 link 24 to move, and the positioning link 24 drives the slide bar 25 to move, so that the slide bar 25 and the bracket 21 are mutually restricted to limit 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 the hydraulic rod 22 is then reset.

[0062] After the assembly is completed, the first clamping member 39 clamps and fixes the assembled rolling bearing assembly, and the first clamping member 39 drives the rolling bearing assembly to move above the blanking slide 317. The first clamping member 39 then releases the clamping, and the assembled rolling bearing assembly falls onto the blanking slide 317 for blanking.

[0063] When replenishing raw materials, the roller 101 and the bushing 102 are arranged and placed on the loading rack 318. When the roller 101 needs to be replenished, the shaft cylinder 319 is started, and the shaft cylinder 319 drives the feeding plate 320 to rotate, so that the feeding plate 320 drives a roller 101 to fall from the loading rack 318, so that the roller 101 falls on the support plate 321 (when the roller 101 needs to be replenished, the first ring frame 34 is moved to the top of the support plate 321, that is, when the roller 101 falls on the support plate 321, the roller 101 will also fall into the inner ring of the first ring frame 34). The roller 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 plate 320 to rotate, so that the feeding plate 320 shifts a bushing 102 to fall from the loading rack 318, so that the bushing 102 falls onto 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 onto 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.
