Description

Technical Field

[0001] The present invention relates to the technical field of chain manufacturing, and in particular to an automatic chain manufacturing system and a manufacturing method. Background Art

[0002] A chain is a mechanical transmission or load-bearing element composed of a series of interconnected links. It is widely used in many fields such as industry, agriculture, transportation, and daily life. Its basic function is to transmit power and torque, or to withstand tension and traction to achieve the connection, transmission or suspension between objects. In order to extend the service life of the chain, it will be lubricated with oil during the chain manufacturing process to reduce the degree of wear during use.

[0003] For example, the Chinese patent "CN112728057B A chain transmission automatic cooling and lubrication device" includes an operating installation box and a chain dragged by an external load, three fixed shafts are provided in the operating installation box, and a rotatable sprocket is provided on the fixed shaft, and the operating installation box includes a box body, a chain inlet hole, two oil storage tanks, an oil storage cavity, two oil inlet holes, an oil seepage hole, a first oil outlet, a second oil outlet and a chain outlet hole, the chain inlet hole and the chain outlet hole are respectively located on both sides of the box body, and the two oil storage tanks are symmetrically opened at the bottom of the inner wall of the box body; the heat generated by friction will be transferred to the lubricating oil in the oil storage cavity, and the lubricating oil will expand due to heat and enter from the first oil outlet, and then be sprayed out from the second oil outlet, so that it can just be sprayed onto the sprocket and the chain, so that the cooling effect of the chain and the sprocket can be achieved, and at the same time, the lubricating oil will drip into the oil storage tank along the chain, completing the collection of the lubricating oil.

[0004] In the current actual application scenarios of lubrication equipment in chain manufacturing, in order to ensure the stability of the operating status of each sprocket, a W-shaped fixed arrangement is generally adopted to arrange the sprockets. This design has many inconveniences in actual operation. In the early assembly stage, the chain needs to be connected to multiple sprockets one by one. The operation process is relatively cumbersome and complicated, and often requires the use of various tools to complete. Since some sprockets will be immersed in lubricating oil, when performing operations such as connecting the chain and sprockets, the lubricating oil is very easy to splash and stain the operator's work clothes, causing clothing contamination. Summary of the Invention

[0005] The present invention relates to an automatic chain manufacturing system and manufacturing method, which solves the problem that in the actual application process of existing chain manufacturing lubrication equipment, in order to ensure the stability of the state of each sprocket, the sprockets mostly adopt a W-shaped fixed arrangement design. In the early stage, it is relatively cumbersome to connect the chain with multiple sprockets in sequence, and the operation process also requires the use of tools. Since some sprockets are immersed in lubricating oil, it is easy for the lubricating oil to be contaminated on work clothes during operation, causing pollution.

[0006] The oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out the side of the oil immersion tank, and the oil pump stretches out

[0007] Furthermore, the fixed sprocket is rotatably connected to the oil immersion box, and sliding holes are provided on opposite sides of the oil immersion box. Both ends of the fixed sprocket are slidably connected to the sliding holes provided in the oil immersion box.

[0008] Furthermore, when the movable sprocket is lifted to the top, the bottom of the movable sprocket is higher than the top of the fixed sprocket. When the movable sprocket falls to the bottom, the movable sprocket is immersed in the lubricating oil inside the oil immersion tank, and the top of the movable sprocket is lower than the bottom of the fixed sprocket. When the chain needs to pass through, the movable sprocket moves to the top so that the movable sprocket is higher than the fixed sprocket, and the chain can be passed across the gap between the movable sprocket and the fixed sprocket. After the chain has passed through, the movable sprocket moves to the bottom, and the chain is connected to the fixed sprocket and the movable sprocket, so that the chain is immersed in the heated lubricating oil.

[0009] Furthermore, the movable sprocket is rotatably connected to the lifting bracket, the inner side of the lifting bracket is in sliding contact with the oil immersion tank, and the outer side of the lifting bracket is in contact with the inner side of the sealing side plate.

[0010] Furthermore, one end of the bottom of the telescopic support frame is rotatably connected to the sealing side plate, and a lower movable hole is provided on the outside of the sealing side plate. The other end of the bottom of the telescopic support frame is slidably connected to the lower movable hole provided on the sealing side plate. One end of the top of the telescopic support frame is rotatably connected to the lifting bracket, and an upper movable hole is provided on the outside of the lifting bracket. The other end of the top of the telescopic support frame is slidably connected to the upper movable hole provided on the lifting bracket. The lifting bracket is driven up and down by the telescopic support frame. When the telescopic support frame extends upward, the telescopic support frame drives the lifting bracket to move upward, and when the telescopic support frame contracts downward, the telescopic support frame drives the lifting bracket to move downward.

[0011] Furthermore, two guide vertical rods are symmetrically provided on the outside of the oil immersion box, and two guide holes are symmetrically provided on the inside of the movable shaft. The guide vertical rods slide through the guide holes provided on the movable shaft, and the guide vertical rods slide and cooperate with the guide holes to guide the movement of the movable shaft.

[0012] Furthermore, the vertical screw is rotatably connected to the oil immersion tank, a screw hole is provided in the middle portion of the movable shaft, and the vertical screw is threadedly connected to the screw hole provided on the movable shaft.

[0013] Furthermore, one end of the transmission rod is rotatably connected to the movable shaft, and the other end of the transmission rod is rotatably connected to the telescopic support frame.

[0014] Furthermore, when the movable shaft moves to the top end, the lifting bracket moves to the bottom end, and when the movable shaft moves to the bottom end, the lifting bracket moves to the top end. When the chain needs to pass through, the vertical screw is rotated, and the vertical screw drives the movable shaft to move downward. The movable shaft drives the two telescopic support frames to extend upward through the transmission rod, and the telescopic support frames drive the lifting bracket to move upward. The lifting bracket drives the movable sprocket to move synchronously, so that the movable sprocket can be moved to the top of the fixed sprocket, meeting the conditions required for the chain to pass through.

[0015] The present invention provides a method for using an AG glass etching device, comprising the following steps: 1) First, rotate the vertical screw, which drives the movable shaft to move downward along the guide vertical rod. The movable shaft drives the two telescopic support frames to extend upward through the transmission rod; 2) The telescopic support frame drives the lifting bracket to move upward, and the lifting bracket drives the moving sprocket to move synchronously, so that the moving sprocket can be moved to the top of the fixed sprocket, and the conditions required for the chain to pass through are met, and the chain can be passed across the gap between the moving sprocket and the fixed sprocket; 3) Next, rotate the vertical screw in the opposite direction, and the vertical screw drives the movable shaft to move upward along the guide vertical rod. The movable shaft drives the two telescopic support frames to retract downward through the transmission rod; 4) The telescopic support frame drives the lifting bracket to move downward, and the lifting bracket drives the moving sprocket to move synchronously, so that the chain is immersed in the lubricating oil; 5) The electric heater heats the lubricating oil in the oil immersion tank, and the circulating filter circulates the lubricating oil. The chain moves under the influence of the traction equipment, and the chain drives the fixed sprocket and the movable sprocket to rotate, thus completing the chain lubrication operation.

[0016] The present invention provides a chain manufacturing method for an automatic chain manufacturing system, which has the following beneficial effects: When the present invention is in use, when it is necessary to perform a chain threading operation, the movable sprocket is controlled to rise to the highest position so that its height exceeds the fixed sprocket. At this time, the chain can be horizontally inserted into the gap area between the movable sprocket and the fixed sprocket; after the chain is successfully threaded, the movable sprocket is moved down to the lowest position to allow the chain to fit tightly against the fixed sprocket and the movable sprocket, ensuring that the chain is completely immersed in the heated lubricating oil; with the lubricating effect of the lubricating oil, the friction of the chain during operation can be effectively reduced, and abnormal noise due to dryness can be avoided. At the same time, the wear of the chain during use can be reduced, thereby extending the service life of the chain.

[0017] In addition, by controlling the telescopic action of the telescopic support frame, the lifting frame is driven to adjust the displacement in the up and down directions; when the telescopic support frame performs an upward extension operation, it will simultaneously drive the lifting frame to achieve an upward vertical movement; and when the telescopic support frame performs a downward contraction action, it will correspondingly drive the lifting frame to complete the downward vertical displacement.

[0018] In addition, the guide vertical rod and the guide hole adopt a sliding fit design, which can effectively guide the movement direction of the movable shaft and ensure its smooth and accurate operation. When the chain needs to pass through the relevant structure, the operator only needs to turn the vertical screw. During the rotation, the vertical screw will drive the movable shaft to move downward. The displacement of the movable shaft is synchronously transmitted to the two telescopic support frames through the transmission rod, prompting the telescopic support frames to extend upward. As the telescopic support frames extend, the lifting brackets connected to them will also rise upward, thereby driving the dynamic sprocket to move upward synchronously until the dynamic sprocket moves to the top position of the fixed sprocket, at which point the necessary conditions are created for the smooth passage of the chain. After the chain completes the horizontal crossing operation, the operator rotates the vertical screw in the opposite direction, and the rotation direction of the vertical screw changes, driving the movable shaft to move upward. The upward movement of the movable shaft acts on the two telescopic support frames again through the transmission rod, causing the telescopic support frames to retract downward. While the telescopic support frames retract, they pull the lifting frames downward, and the lifting frames drive the sprockets to descend synchronously, eventually making the chain completely immersed in the lubricating oil that has been heated to an appropriate temperature, thereby achieving sufficient lubrication of the chain. The entire operation process is simple and smooth, without the need for complicated steps, which greatly improves the convenience and efficiency of operation.
