Description

Technical Field

[0001] The present invention relates to the technical field of bearing assembly, and particularly relates to a bearing assembly workbench. Background Art

[0002] The invention patent with the publication number CN113483029A discloses a bearing assembly device, which includes a machine table for transporting an inner ring and an outer ring, and a frame vertically arranged on the machine table. A box body for containing balls is arranged on the frame. A plurality of first holes for the balls to roll down are evenly distributed on the bottom wall of the box body, and the plurality of first holes are all located on the same circumference. A conical cylinder for collecting the balls rolling out of the box body is arranged below the box body. A control mechanism for controlling the quantitative rolling of the balls is arranged between the box body and the conical cylinder. One end of the conical cylinder far away from the box body is communicated with a conduit for transporting the balls one by one, and one end of the conduit far away from the conical cylinder points to the gap between the inner ring and the outer ring on the machine table. The above application ensures that the number of balls rolling between the inner ring and the outer ring is consistent with the number of balls required for assembly.

[0003] However, in the actual use process, due to the action of the gravity of the balls and the smoothness of the balls, the speed of the balls during falling is extremely fast. During assembly, it is very easy to have errors in the number of balls, affecting the qualification rate of the bearings. At the same time, when assembling the inner ring and the outer ring of the bearing, manual or mechanical hands need to be used for control, which requires connecting other equipment, with low efficiency and high equipment cost, and is not conducive to the assembly of bearings.

[0032] 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.

[0033] Please refer to Figure 1 - Figure 8 As shown, the present invention is a bearing assembly workbench, including a machine platform 1. A return mold conveyor line 4 is arranged above the machine platform 1. The structure of the return mold conveyor line 4 is as Figure 8As shown, two symmetrically arranged electric rollers and two conveyor belts are adopted to convey the support mold of the bearing. Then, an assembly conveyor line 3 is arranged above the mold return conveyor line 4. A top mold assembly 5 is arranged at one end of the machine table 1 where the mold return conveyor line 4 is located, and a bottom mold assembly 7 is arranged at the other end. Secondly, a pushing material vertical frame 15 is arranged on one side of the machine table 1 where the mold return conveyor line 4 is located. Then, a pushing material telescopic rod 16 is arranged on one side of the pushing material vertical frame 15, and a pushing material rubber block 161 is fixedly arranged on the extending end of the pushing material telescopic rod 16. The pushing material telescopic rod 16 is inclined. When the inner ring and the outer ring of the bearing are conveyed to one side of the pushing material vertical frame 15 together, the pushing material telescopic rod 16 extends to push the inner ring to one side of the outer ring to contact the outer ring. In addition, a ball mounting assembly 6 is arranged above the middle of the mold return conveyor line 4. Then, feeding vertical frames 11 are symmetrically arranged at one end close to the top mold assembly 5 above the mold return conveyor line 4.

A clamping telescopic rod 145 is arranged on one side above the fixing block 144, and a clamping block 146 is fixedly arranged on the extending end of the clamping telescopic rod 145. By the telescopic movement of the clamping telescopic rod 145, the clamping block 146 can be controlled to move, so as to clamp and move the inner ring and the outer ring of the bearing. Finally, a material distributing assembly 2 is symmetrically arranged on the machine table 1 and below the feeding suspension 12.

[0034] Specifically, a feeding suspension 12 is arranged on one side of the feeding vertical frame 11. A feeding guide rail 13 is arranged on the opposite side of the two feeding suspensions 12. Then, the feeding frame 14 is slidably arranged between the two feeding guide rails 13. A feeding telescopic rod 141 is arranged on one side of a feeding suspension 12, and the extending end of the feeding telescopic rod 141 is fixedly connected to the feeding frame 14.

[0035] Specifically, the material separating assembly 2 includes a material separating turntable 21 rotatably arranged on the machine table 1. A turntable motor 20 is arranged inside the machine table 1, and the output end of the turntable motor 20 is fixedly connected to the material separating turntable 21. A material separating baffle 22 is arranged on the machine table 1 and outside the material separating turntable 21. Two guide plates 23 are arranged inside the material separating baffle 22. One end of the guide plate 23 close to the center of the material separating baffle 22 is provided with a material guiding port 230. Then, a connecting material guiding line 24 is arranged outside the material separating baffle 22 and close to one end of the guide plate 23. A material separating line 25 is connected to the end of the connecting material guiding line 24. The other end of the material separating line 25 is located directly below the feeding suspension 12. The two material separating assemblies 2 respectively separate and convey the inner ring and outer ring of the bearing. Place the outer ring and inner ring of the bearing on the material separating turntable 21 respectively. Under the rotation of the material separating turntable 21 and in cooperation with the function of the guide plate 23, the inner ring or outer ring of the bearing can be respectively led out through the material guiding port 230 and conveyed along the two guide plates 23 to the connecting material guiding line 24, and then conveyed to the material separating line 25, so that the assembly work can be carried out. It ensures the continuity of the conveyance of the inner ring and outer ring during the bearing assembly process. At the same time, there is no need for a manipulator to place them in sequence, greatly improving the assembly continuity, saving costs and ensuring efficiency.

[0036] In addition, the ball installing assembly 6 includes a ball rack 61 fixedly installed above the return die conveying line 4. A ball box 610 is arranged above the ball rack 61. Then, a limiting shell 611 is arranged below the ball box 610. A ball dropping pipe 612 is arranged below the limiting shell 611. A spring pipe 63 is connected to the lower end of the ball dropping pipe 612. Then, a pressing block 65 is connected to the end of the spring pipe 63. An anti-slip pad 651 is arranged at the bottom of the pressing block 65. An inner cavity channel 650 is opened in the middle of the pressing block 65. In addition, a ball telescopic rod 64 is fixedly arranged inside the ball rack 61, and the extending end of the ball telescopic rod 64 is fixedly connected to the pressing block 65. Finally, a counting disk 62 is rotatably arranged inside the limiting shell 611, and a number of counting grooves 620 are arranged in a circular array on the counting disk 62. A counting motor 621 is arranged on one side outside the limiting shell 611, and the output end of the counting motor 621 is fixedly connected to the counting disk 62. When the inner ring and outer ring of the bearing are conveyed below the ball rack 61 under the action of the pushing telescopic rod 16, the ball telescopic rod 64 extends downward, so that the pressing block 65 presses on the inner ring and outer ring. At this time, the counting motor 621 can be driven to drive the counting disk 62 to rotate, and the balls in the ball box 610 can be further conveyed into the ball dropping pipe 612 in sequence, and then fall between the inner ring and outer ring. The ball installation efficiency is high, and at the same time, the error in the number of balls during the installation process is avoided, reducing the error rate of the number of balls during the bearing assembly process.

[0037] Secondly, the upper die assembly 5 includes an upper die cylinder 51 fixedly arranged inside the machine table 1 and at one end of the mold-return conveying line 4, and an upper template 52 is fixedly arranged on the extending end of the upper die cylinder 51; the upper die assembly 5 further includes an upper die support 53 fixedly arranged on the machine table 1, an upper die photoelectric inductor 54 is arranged on the upper die support 53, and then an upper die pushing cylinder 55 is arranged on the top of the upper die support 53. After the empty bearing assembly support mold is conveyed onto the upper template 52 and contacts the upper die photoelectric inductor 54, the upper die cylinder 51 rises to lift the support mold to a position aligned with the assembly conveying line 3. At this time, the upper die pushing cylinder 55 pushes the support mold onto the assembly conveying line 3, and then the inner ring and the outer ring are clamped by the clamping blocks 146 and placed on the support mold. Through the action of the upper die assembly 5, the problem of the movement of the support mold during the assembly process is solved, ensuring the rapidity of the assembly.

[0038] It should be noted that: the two clamping blocks 146 respectively clamp the inner ring and the outer ring and can be placed simultaneously, that is, the front clamping block 146 places the outer ring, and the latter clamping block 146 places the inner ring inside the previous outer ring, and so on.

[0039] Finally, the lower die assembly 7 includes a lower die cylinder 71 fixedly arranged inside the machine table 1 and at the other end of the mold-return conveying line 4, and a lower template 72 is fixedly arranged on the extending end of the lower die cylinder 71; the lower die assembly 7 further includes a lower die support 73 fixedly arranged on the machine table 1, a lower die photoelectric inductor 74 is arranged on the top of the lower die support 73, and a lower die pushing cylinder 75 is arranged inside the lower die support 73. The working principle of the lower die assembly 7 is the same as that of the upper die assembly 5, and no further elaboration will be made here.

[0040] During the assembly, a robotic arm can be arranged at other positions on the machine table 1 to grab the assembled bearings. At the same time, the empty support mold returns along the mold-return conveying line 4 under the action of the lower die assembly 7, effectively ensuring the efficiency of the bearing during the assembly process and the qualification rate of the bearing assembly.
