[0016] A working method of an automobile engine sleeve chain automatic link device comprises the following steps:

[0017] (1) The chain to be disassembled is driven by the first servo motor to move along the chain conveying guide rail. When the number of chain links of the chain to be disassembled on the side of the disassembling device away from the first servo motor meets the set standard, the first servo motor and the second servo motor stop moving, the disassembling device completes the disassembly, and the chain on the side of the disassembling device away from the first servo motor constitutes the disassembled chain;

[0018] (2) The disassembled chain is connected end to end by a chain end-to-end connection device: when the end of the disassembled chain reaches the end of the chain conveying guide rail and is located at the initial position of the lower positioning pin 1, the lower positioning pin 1 passes through the through hole driven by the first cylinder and is inserted into the sleeve hole at the end of the disassembled chain. Then, the plate bodies of the two lifting guide plates retract into the through hole, the negative pressure device is started, and the guide sprocket is driven by the second servo motor to gradually guide the disassembled chain into area A on the side of the machine away from the chain link mechanism. In order to ensure that the guide channel of the chain is unobstructed, the feeding cylinder drives the lower positioning pin 1 to move a set distance to the side away from area A. During the movement, the rotation speed of the guide sprocket is coordinated to prevent the disassembled chain from being completely separated from the guide sprocket. At the same time Due to the effect of negative pressure, the sleeve of the disassembled chain is adsorbed in the tooth valley, and the disassembled chain is introduced into area A section by section under the drive of the guide sprocket, and the function of the block is to block the chain links meshing at the bottom gear of the guide sprocket, so that the disassembled chain is separated from the guide sprocket and spread out in area A; when the guide sprocket guides the sleeve hole at the head end of the disassembled chain to the set position, the lateral distance between the sleeve hole at the head end and the sleeve hole at the tail end to be positioned is the same as the pitch P of the chain to be linked, at this time, the first servo motor and the second servo motor stop working, and under the drive of the feeding cylinder, the lower positioning pin 2 retreats to the sleeve hole at the head end, and is inserted into the sleeve hole at the head end under the drive of the second cylinder, thereby realizing the positioning of the sleeve holes at the head and tail ends of the disassembled chain, that is, the chain is connected head to tail;

[0019] (3) With the cooperation of the translation mechanism, the linear drive mechanism, the feeding cylinder, the first cylinder, and the second cylinder, the chain head-to-tail connecting device simultaneously sends the head end and the tail end of the disassembled chain into the designated position in the link positioning device at the material receiving station, and the link positioning device clamps the head end and the tail end to position, and then the chain head-to-tail connecting device resets; the third servo motor is activated to drive the head end and the tail end to enter the pin shaft installation station, the sheet installation station, the head exposure station, the riveting head station, and the chain removal station in turn, and finally the chain with good links is taken out at the chain removal station;

[0020] (4) After the chain head-to-tail connection device is reset, steps (1), (2), and (3) are repeated to achieve the automatic linking of the chain after continuous disassembly.

[0021] The beneficial effects of the automobile engine sleeve chain automatic link device and method of the present invention are:

[0022] The present invention can realize the continuous automation of automobile engine sleeve chains and similar small sleeve chains, significantly improve production efficiency, ensure production quality, and overcome the problems of high labor intensity, potential safety hazards, and difficult quality assurance caused by manual operation.

The negative pressure holes 4-151 are arranged along the radial direction of the axle and pass through the tooth valley of the guide sprocket 4-15. The guide sprocket 4-15 is chain-engaged after disassembly; the top of the machine table corresponding to the bottom gear of the guide sprocket 4-15 is provided with a stopper 4-20 for disengaging the chain from the guide sprocket after disassembly.

[0047] In this embodiment, after the disassembly device is disassembled, the disassembled upper chain piece, lower chain piece and pin shaft enter the collecting box through the leakage hole, usually by blowing these parts into the leakage hole. At this time, the chain on the side of the disassembly device away from the first servo motor constitutes the disassembled chain. Figure 12-14 As shown, the purpose of setting the first servo motor and the second servo motor to run synchronously is to maintain the pitch between the end of the chain to be disassembled and the beginning of the chain after disassembly, and the front and rear two chains move synchronously, so that the subsequent disassembled chain can accurately cooperate with the guide sprocket. Compared with the method of using the chain on the rear side to push the disassembled chain to move, the position control of the disassembled chain is more accurate. After the lower positioning pin 4-3 positions the sleeve hole 4-13 at the tail end of the disassembled chain, the plate bodies of the two lifting guide rail plates descend into the through holes, the negative pressure device is started, and driven by the second servo motor, the guide sprocket moves, and the disassembled chain 4-11 is gradually introduced into the area A4-17 on the side of the machine 6 away from the chain link mechanism 4. In order to ensure that the guide channel of the chain is unobstructed, the feeding cylinder drives the lower positioning pin 1 to move a certain distance toward the side of the chain link mechanism 4; at the same time, due to the effect of negative pressure, the sleeve of the disassembled chain is adsorbed in the tooth valley, thereby ensuring the guidance of the disassembled chain 4-11 and will not separate from the guide sprocket 4-15, and the function of the block 4-20 is to block the disassembled chain 4-11 adsorbed on the bottom gear of the guide sprocket 4-15, so that the disassembled chain separates from the guide sprocket and accumulates in the area A4-17; Fig.14As shown, when the guide sprocket 4-15 guides the sleeve hole 4-12 of the head end of the chain after disassembly to the set position, the lateral distance between the sleeve hole 4-13 of the head end and the sleeve hole 4-13 of the tail end to be positioned is the same as the pitch of the chain to be linked. At this time, the second servo motor stops working, and the lower positioning needle 2 retreats to the sleeve hole 4-12 of the head end under the drive of the feeding cylinder, and is inserted into the sleeve hole 4-12 of the head end under the drive of the second cylinder, thereby realizing the positioning of the sleeve holes of the head and tail ends of the chain after disassembly, that is, the chain is connected head to tail. The lower positioning needle 1 and the lower positioning needle 2 are inserted into the two sleeve holes to the same depth, and after insertion, it can be ensured that the head end and the tail end will not fall off (which can be achieved by setting elastic material on the positioning needle). At the same time, it is ensured that the head end and the tail end are at the same height. Under the cooperation of the translation mechanism and the linear drive mechanism, the lower positioning needle 1 and the lower positioning needle 2 move to a position relative to the material receiving station.

Driven by the third servo motor, the six link positioning devices 11 sequentially pass through the material receiving station, the pin shaft installation station, the sheet installation station, the head exposure station, the riveting station, and the chain removal station to realize all the chain link processes.

[0049] In a further embodiment, Figure 1-3 As shown in , 5 and 6, the material receiving station is arranged opposite to the chain end-to-end connecting device 3.

When the number of chain links of the chain to be disassembled on the side of the disassembling device away from the first servo motor meets the set standard, the first servo motor and the second servo motor stop moving, the disassembling device completes the disassembly, and the chain on the side of the disassembling device away from the first servo motor constitutes the disassembled chain; (2) The disassembled chain is connected end to end by a chain end-to-end connection device: when the end of the disassembled chain reaches the end of the chain conveying guide rail and is located at the initial position of the lower positioning pin 1, the lower positioning pin 1 passes through the through hole driven by the first cylinder and is inserted into the sleeve hole at the end of the disassembled chain. Then, the plate bodies of the two lifting guide plates retract into the through hole, the negative pressure device is started, and the guide sprocket is driven by the second servo motor to gradually guide the disassembled chain into area A on the side of the machine away from the chain link mechanism. In order to ensure that the guide channel of the chain is unobstructed, the feeding cylinder drives the lower positioning pin 1 to move a set distance to the side away from area A. During the movement, the rotation speed of the guide sprocket is coordinated to prevent the disassembled chain from being completely separated from the guide sprocket. At the same time Due to the effect of negative pressure, the sleeve of the disassembled chain is adsorbed in the tooth valley, and the disassembled chain is introduced into area A section by section under the drive of the guide sprocket, and the function of the block is to block the chain links meshing at the bottom gear of the guide sprocket, so that the disassembled chain is separated from the guide sprocket and spread out in area A; when the guide sprocket guides the sleeve hole at the head end of the disassembled chain to the set position, the lateral distance between the sleeve hole at the head end and the sleeve hole at the tail end to be positioned is the same as the pitch P of the chain to be linked, at this time, the first servo motor and the second servo motor stop working, and under the drive of the feeding cylinder, the lower positioning pin 2 retreats to the sleeve hole at the head end, and is inserted into the sleeve hole at the head end under the drive of the second cylinder, thereby realizing the positioning of the sleeve holes at the head and tail ends of the disassembled chain, that is, the chain is connected head to tail; (3) With the cooperation of the translation mechanism, the linear drive mechanism, the feeding cylinder, the first cylinder, and the second cylinder, the chain head-to-tail connecting device simultaneously sends the head end and the tail end of the disassembled chain into the designated position in the link positioning device at the material receiving station, and the link positioning device clamps the head end and the tail end to position, and then the chain head-to-tail connecting device resets; the third servo motor is activated to drive the head end and the tail end to enter the pin shaft installation station, the sheet installation station, the head exposure station, the riveting head station, and the chain removal station in turn, and finally the chain with good links is taken out at the chain removal station; (4) After the chain head-to-tail connection device is reset, steps (1), (2), and (3) are repeated to achieve the automatic linking of the chain after continuous disassembly.
