Description

Technical Field

[0001] The present invention belongs to the technical field of double-speed chains, and particularly relates to a double-speed chain with a built-in stable auxiliary component. Background Art

[0002] A double-speed chain is a special transmission device, which is widely used in various mechanical equipment, especially in conveying systems and automated production lines. The characteristic of a double-speed chain is that it can transmit power at different speeds, so as to achieve the efficient conveying and processing of workpieces. In the prior art, the key components of a double-speed chain usually consist of two sprockets with different diameters, a large sprocket and a small sprocket. By adjusting the tooth ratio of the large sprocket and the small sprocket, a double-speed transmission is achieved. If the number of teeth of the large sprocket is twice that of the small sprocket, the rotational speed of the chain will be twice that of the driving shaft. When the double-speed chain runs at high speed, its performance and service life may be affected by vibration, impact and unstable factors. In order to improve the stability and reliability of the double-speed chain, some auxiliary components can be set to help with stable operation.

[0003] The Chinese patent document with the publication number CN107055057B proposes a transfer mechanism for a double-speed chain conveyor line.

[0031] In order to clearly and completely describe the purpose, technical solution of the present invention, and make the advantages more clear, the following further details the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are part of the embodiments of the present invention, rather than all of the embodiments, and are only used to explain the embodiments of the present invention, not to limit the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0032] Embodiment 1, please refer to Figures 1 to 13, the present invention provides a technical solution: a speed chain with a built-in stable auxiliary component, including a speed chain installation base 1. Symmetrically and fixedly installed on the outer side of the upper surface of the speed chain installation base 1 are outer support plates 2. Fixedly installed in the middle of the upper surface of the speed chain installation base 1 is an inner support plate 3. A speed chain 4 is movably installed between the inner support plate 3 and the outer support plate 2. On one side of the speed chain installation base 1 is provided a speed chain driving component 5 for driving the rotation of the speed chain 4. Above the speed chain 4 is provided a lubrication component 6. Inside the speed chain 4 is provided a stable auxiliary guide rail component 7. The lubrication component 6 includes a lubricating oil box 61, a top cover 62 and an external guide rail 63. The stable auxiliary guide rail component 7 includes an H-shaped adjustment guide rail support frame 71, a calibration auxiliary guide rail 72 and an adjustment driving component 73. The lubricating oil box 61 is symmetrically and fixedly installed above the outer support plate 2 and the inner support plate 3. Fixedly installed on the upper surface of the lubricating oil box 61 is a top cover 62. Fixedly installed on the lower surface of the side of the top cover 62 close to the speed chain 4 is an external guide rail 63. Inside the lubricating oil box 61 are provided an oil groove 611 and a rising oil passage 612. An oil outlet groove is opened below the side wall adjacent to the oil groove 611 and the rising oil passage 612. At the bottom of the inner surface of the rising oil passage 612 is provided a sealing piston pad 6121. Fixedly installed at the bottom of the lubricating oil box 61 is a telescopic rod 64. The output end of the telescopic rod 64 penetrates through the bottom inner wall of the rising oil passage 612 and is fixedly connected to the lower surface of the sealing piston pad 6121. At intervals on the inner wall of the top cover 62 are provided lubricating oil channels 621. Above the external guide rail 63 is provided an oil immersion port adapted to the lubricating oil channels 621. One side of the external guide rail 63 is set as an inclined surface. Inside the external guide rail 63 are evenly distributed cylindrical ball bearings;In this embodiment, it should be noted that external guide rails identical to the external guide rail 63 are symmetrically and fixedly installed below the inner surfaces of the outer support plate 2 and the inner support plate 3. The inner guide rail 722 proposed below also has the same structure as the external guide rail 63, which plays a role in stably supporting and guiding both sides of the double-speed chain 4. One side of the external guide rail 63 is set as an inclined surface, and the symmetrical laying can play a guiding role on both sides when the double-speed chain 4 runs. The inclined surface design can effectively reduce the lateral offset of the double-speed chain 4 during operation, ensure that the double-speed chain 4 runs along a predetermined path, reduce vibration and shaking. And evenly laying cylindrical ball bearings on the surface of the external guide rail 63 and along the inclined surface can reduce the lateral offset of the double-speed chain 4 during operation, and can reduce the wear between the double-speed chain 4 and the guide rail, extend the service life of the double-speed chain 4. And the inclined surface design can better absorb the impact and vibration during the operation of the lubrication component 6, reduce the direct contact area between the double-speed chain 4 and the guide rail, thereby reducing the frictional resistance, and can improve the reliability and stability of the transportation system. The oil groove 611 inside the lubricating oil box 61 is used to store lubricating oil. One end of the lubricating oil box 61 is provided with a lubricating oil injection pipe. The lubricating oil inside the oil groove 611 enters the rising oil passage 612 through the oil outlet groove. When the telescopic rod 64 is started, the sealing piston pad 6121 can be pushed up, so that the lubricating oil inside the rising oil passage 612 rises and enters the lubricating oil passage 621 and finally drains into the external guide rail 63. When the double-speed chain 4 runs, it infiltrates the double-speed chain 4 through the gaps between the cylindrical ball bearings, plays a certain lubricating role on the double-speed chain 4, and can effectively reduce the wear of the double-speed chain 4 and extend the service life of the double-speed chain 4.;

[0033] Embodiment Two. Please refer to Figures 1 to 13 , on the basis of Embodiment One, this embodiment also proposes that the H-shaped adjusting guide rail support frame 71 is symmetrically and slidably installed up and down between the outer support plate 2 and the inner support plate 3. A limiting sliding groove adapted to the H-shaped adjusting guide rail support frame 71 is provided on the side surface of the outer support plate 2. Tooth plates 711 are fixedly installed on the surfaces of the upper and lower groups of H-shaped adjusting guide rail support frames 71 in an alternating manner. An adjusting drive component 73 is provided in the middle of the upper surface of the inner support plate 3. Gear 731 is symmetrically and fixedly installed at both ends of the rotating shaft of the adjusting drive component 73. The side surfaces of the gears 731 are respectively meshed with the side surfaces of the tooth plates 711; In this embodiment, when the adjusting drive component 73 works, the rotation of the gear 731 drives the tooth plate 711 to move up and down, so that the H-shaped adjusting guide rail support frame 71 can move up and down under the action of the limiting sliding groove on the inner side of the outer support plate 2 for pitch adjustment, can be adjusted according to the running tension of the double-speed chain 4, limit the double-speed chain 4, and make the double-speed chain 4 run more stably. When the H-shaped adjusting guide rail support frame 71 moves closer and the pitch increases, it is convenient for the disassembly, maintenance, replacement and installation of the double-speed chain 4.

[0034] Embodiment Three. Please refer to Figures 1 to 13, on the basis of the second embodiment, this embodiment further proposes that the calibration auxiliary guide rail 72 is symmetrically and fixedly installed on one side of the H-shaped adjustment guide rail support frame 71 close to the double-speed chain 4. The movable support pads 721 are evenly and dispersedly distributed inside the calibration auxiliary guide rail 72. On the side of the movable support pad 721 in contact with the double-speed chain 4, an inner guide rail 722 is fixedly installed. The structure of the inner guide rail 722 is the same as that of the outer guide rail 63. On one side surface of the movable support pad 721, shock-absorbing arc-shaped feet 7211 are symmetrically and fixedly installed. On the inner surface of the calibration auxiliary guide rail 72, a foot installation groove 723 adapted to the shock-absorbing arc-shaped feet 7211 is fixedly installed. In the middle of one side surface of the movable support pad 721, a to-be-calibrated block 7212 is fixedly installed. A calibration block 724 is slidably installed on the inner wall of the calibration auxiliary guide rail 72. An irregular calibration roller 725 is rotatably installed in the middle of the inner wall of the calibration auxiliary guide rail 72. At one end of the calibration auxiliary guide rail 72, an independent control motor 726 for driving the irregular calibration roller 725 to rotate is fixedly installed; in this embodiment, the movable support pads 721 inside the calibration auxiliary guide rail 72 are evenly and dispersedly arranged, combined into a long strip to support and install the inner guide rail 722, which can provide uniform support force. Uniform support can reduce the deformation of the guide rail caused by uneven force, improve the straightness and surface smoothness of the guide rail, and ensure the stability of the guide rail within the full length. The shock-absorbing arc-shaped feet 7211 can move inside the foot installation groove 723 to buffer the vibration generated during the operation of the double-speed chain 4, reduce wear and fatigue damage. After the double-speed chain 4 has been in operation for a period of time, the independent control motor 726 works to drive the irregular calibration roller 725 to rotate to lift the calibration block 724. The calibration block 724 centrally calibrates the to-be-calibrated block 7212, which can ensure that the accuracy of all support points is consistent, avoid the overall error caused by the deviation of individual support points, achieve high-precision calibration, ensure the straightness and surface smoothness of the guide rail, reduce the deformation of the guide rail caused by uneven force, improve the stability of the operation of the double-speed chain 4. Uniform support and calibration can also reduce the fault points, reduce the maintenance frequency, reduce the maintenance cost, improve the operation efficiency of the transportation system. Stable operation can increase the running speed of the double-speed chain 4 and improve the production efficiency.

[0035] Embodiment 4, please refer to Figures 1 to 13, on the basis of Embodiment III, this embodiment further proposes an operation method of a speed chain with a built-in stable auxiliary component, including the following steps: Step 1, perform support tension adjustment according to the speed chain 4. Adjust the operation of the driving component 73 to drive the toothed plate 711 to move up and down through the rotation of the gear 731, so that the H-shaped adjustment guide rail support frame 71 can move up and down under the action of the inner limit chute of the outer support plate 2 to perform spacing adjustment, and adjust according to the operation tension of the speed chain 4 to limit the speed chain 4; Step 2, perform lubrication. The telescopic rod 64 is activated to lift the sealing piston pad 6121, so that the lubricating oil inside the rising oil passage 612 rises and enters the lubricating oil passage 621 and finally drains into the external guide rail 63, and infiltrates the speed chain 4 through the gaps between the cylindrical ball bearings when the speed chain 4 is running; Step 3, perform calibration. When the speed chain 4 has been running for a period of time, the independent control motor 726 is operated to drive the special-shaped calibration roller 725 to rotate to lift the calibration block 724, and the calibration block 724 centrally calibrates the calibrated block 7212, which can ensure that the accuracy of all support points is consistent.
