Description

Technical Field

[0001] This utility model relates to the technical field of chain assembly equipment, and in particular to an automatic chain assembly equipment. Background Technology

[0002] Chains, as a fundamental mechanical transmission component, are widely used in motorcycles, bicycles, industrial equipment, agricultural machinery, and other fields. Chains typically consist of inner chain plates, outer chain plates, pins, and bushings. Production demand is enormous, requiring high assembly efficiency and precision. To improve production efficiency, various automated chain assembly machines have emerged on the market. These automated chain assembly machines typically use vibratory feeders, automatic feeding mechanisms, and other automated feeding devices to transport small parts such as inner chain plates, outer chain plates, pins, and bushings to the assembly station. The automated assembly components on the machine, in conjunction with a pressing mechanism, press the parts into the inner and outer chain plates to form chain links.

[0003] In existing automatic chain assembly equipment, the I-shaped pressure frame relies on guide slides and guide cylinders for guidance. However, since the guide cylinder is not equipped with an effective circulating lubrication structure, the lubricating oil tends to deposit at the bottom of the guide cylinder under the action of gravity. This makes it difficult to form an effective oil film on the contact surface between the guide slide and the guide cylinder, resulting in lubrication failure. The resulting dry friction not only aggravates the wear of parts, but also leads to increased equipment operating resistance, decreased accuracy, and even abnormal noise, seriously affecting the stability and service life of the automatic chain assembly equipment.

The transparent oil storage tank and oil delivery mechanism include a piston cylinder, which is fixedly connected to the lower front end of the main body of the equipment via a U-shaped fixing block. A piston rod is slidably connected to the U-shaped fixing block, and a piston is located inside the piston cylinder at the right end of the piston rod. The lower oil suction port of the piston cylinder is connected to the oil outlet at the bottom of the transparent oil storage tank via a pipe. The upper oil outlet of the piston cylinder is connected to a T-shaped pipe, and both ends of the upper part of the T-shaped pipe are connected to a diverter pipe, which is connected to the oil inlet head. The upper oil inlet of the transparent oil storage tank is connected to two manifold pipes, which are connected to the oil outlet head.

[0006] Furthermore, the left and right ends of the I-shaped lower pressure frame are fixedly connected with reciprocating drive components that penetrate the top of the equipment body, and the lower end of the reciprocating drive components is connected to the output end of the drive device installed inside the equipment body.

[0007] Furthermore, a flow-blocking sleeve is provided at the edge of the upper end face of the guide cylinder; a through hole is provided on the sliding bushing, and the through hole on the sliding bushing is on the same axis as the oil inlet pipe head.

[0008] Furthermore, the upper right side of the transparent oil tank is provided with left and right filling ports, and the upper end of the filling ports is connected with a threaded cap by a thread.

[0009] Furthermore, a one-way valve is installed on both the lower oil inlet and the upper oil outlet of the piston cylinder. The upper one-way valve can only discharge oil and not allow oil to enter, while the lower one-way valve can only allow oil to enter and not allow oil to exit.

[0011] This utility model provides an automatic chain assembly device, which has the following beneficial effects: This invention, through the coordinated design of the oil delivery mechanism and the transparent oil storage tank, enables the linkage component to drive the oil delivery mechanism during the automatic chain assembly process. This allows the oil delivery mechanism to automatically transport the lubricating oil from the transparent oil storage tank to the sliding bushing, forming an effective oil film on the contact surface between the sliding bushing and the guide column. Subsequently, the lubricating oil falls to the lower side of the guide cylinder under gravity and flows back to the transparent oil storage tank through the oil outlet head and manifold, forming a top-down circulating lubrication. This avoids lubrication failure and dry friction, effectively reduces component wear, lowers equipment operating resistance, improves assembly accuracy, and prevents abnormal noise. Therefore, it significantly improves the stability and service life of this automatic chain assembly equipment.

The oil suction port at the lower end of the piston cylinder 401 is connected to the oil outlet at the bottom of the transparent oil storage tank 3 through a pipe. A three-way pipe 404 is connected to the oil outlet at the upper end of the piston cylinder 401, and a diverter pipe 405 is connected to both ends of the upper part of the three-way pipe 404.

Two manifold pipes 303 are connected to the oil inlet at the upper end of the transparent oil storage tank 3, and the manifold pipes 303 are connected to the oil outlet head 108. Through the cooperative design of the oil delivery mechanism 4 and the transparent oil storage tank 3, a top-down circulating lubrication is formed, thereby avoiding lubrication failure and dry friction, effectively reducing the wear of parts, reducing the operating resistance of the equipment, improving the assembly accuracy, and avoiding abnormal noise. Therefore, the stability and service life of this automatic chain assembly equipment are improved.

[0018] The left and right ends of the I-shaped pressure frame 103 are fixedly connected with reciprocating drive components 104 that penetrate the top of the main body 1 of the equipment, and the lower end of the reciprocating drive component 104 is connected to the output end of the drive device installed inside the main body 1 of the equipment (the drive device is a mature existing technology and will not be described in detail).

[0019] A flow-blocking sleeve 106 is provided at the edge of the upper end face of the guide cylinder 101; a through hole is provided on the sliding bushing 109, and the through hole on the sliding bushing 109 is on the same axis as the oil inlet pipe head 107, so as to facilitate the lubricating oil to enter the interior of the sliding bushing 109.

[0020] The upper right side of the transparent oil tank 3 is provided with left and right filling ports 301, and the upper end of the filling port 301 is connected to a threaded cap 302 by a thread for adding lubricating oil into the transparent oil tank 3.

[0021] A one-way valve 407 is installed on both the lower oil inlet and the upper oil outlet of the piston cylinder 401. The upper one-way valve 407 can only discharge oil and cannot discharge oil, while the lower one-way valve 407 can only discharge oil and cannot discharge oil.

[0022] Example 2, based on Example 1, such as Figure 1 , Figure 3 and Figure 6 As shown, it also includes a linkage component 5, which is installed on the upper surface of the equipment body 1. The linkage component 5 includes a rectangular linkage rod 501 and a rotating shaft 504. A rectangular slide cylinder 502 fixed to the upper surface of the equipment body 1 is slidably connected to the outside of the rectangular linkage rod 501, and a rack 503 is installed on one side of the lower part of the rectangular linkage rod 501. The rotating shaft 504 is rotatably connected to the front end face of the equipment body 1, and the rear end of the rotating shaft 504 is fixedly connected to the inner ring of a one-way bearing 505. A gear 5 is installed on the outer ring of the one-way bearing 505. 06, and gear 506 meshes with rack 503, a linkage disc 507 is installed at the front end of rotating shaft 504, and a connecting rod 508 is rotatably connected to the edge of the front end face of linkage disc 507 through a rotating shaft, and the other end of connecting rod 508 is rotatably connected to the left end of piston rod 403 through a rotating shaft; through the design of linkage component 5, the linkage component 5 can be driven to operate synchronously by the up and down reciprocating movement of I-shaped lower pressure frame 103, so that when driving oil delivery mechanism 4 to operate, there is no need to install a separate motor or other drive equipment, reducing cost and power consumption.

[0023] The working principle of this embodiment is as follows: When in use, the automatic feeding mechanism 2 automatically feeds small parts such as inner chain plates, outer chain plates, pins and sleeves to the assembly station. Then, the automatic assembly component 105 on the main body of the equipment 1, together with the I-shaped pressure frame 103, the reciprocating drive component 104 and the drive device, presses the above chain parts into the inner and outer chain plates to form chain links, thereby realizing automatic chain assembly.

[0024] During the automatic assembly of the chain, the drive device installed inside the main body of the equipment 1 drives the I-shaped lower pressure frame 103 to move up and down reciprocally via the reciprocating drive component 104. The reciprocating movement of the I-shaped lower pressure frame 103 drives the rectangular linkage rod 501 and the rack 503 to move up and down synchronously. When the rack 503 moves downward, it drives the gear 506, the outer ring of the one-way bearing 505, the inner ring of the one-way bearing 505, the rotating shaft 504, and the linkage disc 507 to rotate counterclockwise. When the rack 503 moves upward, it can only drive the outer ring of the gear 506 and the one-way bearing 505 to rotate clockwise. At this time, the inner ring of the one-way bearing 505, the rotating shaft 504, and the linkage disk 507 do not rotate, so that the linkage disk 507 can only rotate counterclockwise. The rotating linkage disk 507 drives the left end of the connecting rod 508 to rotate, while the right end of the connecting rod 508 will drive the piston rod 403 and the piston 406 to move back and forth. When the piston moves to the left, it creates suction at the lower oil inlet of the piston cylinder 401, drawing lubricating oil from the transparent oil tank 3 into the piston cylinder 401. Then, when the piston 406 moves to the right, it pushes the lubricating oil from the piston cylinder 401 into the three-way pipe 404, the branch pipe 405, the oil inlet pipe head 107, and the sliding bushing 109. This creates an effective oil film on the contact surface between the sliding bushing 109 and the guide column 102. Under gravity, the lubricating oil falls to the lower side of the guide cylinder 101 and then flows back into the transparent oil tank 3 through the oil outlet pipe head 108 and the manifold 303. This provides a top-down circulating lubrication effect between the sliding bushing 109 and the guide column 102, preventing lubrication failure and dry friction. This not only effectively reduces wear on parts but also reduces increased operating resistance, improves assembly accuracy, and avoids abnormal noise. Therefore, it effectively improves the stability and service life of this automatic chain assembly equipment.
