Description

Technical Field

[0001] The present invention relates to the technical field of plate chain production, and particularly relates to a plate chain production process. Background Art

[0002] A plate chain is a multi-purpose mechanical basic part composed of rigid components to form a flexible system, mainly used to meet the functional requirements of transmission, conveying, pulling, etc.; its main structure is composed of chain plates and chain shafts arranged in a certain order in a cycle and riveted.

[0003] The existing plate chain production equipment generally includes a plate chain assembly system, a missing part detection system, a live joint stretching system, an oil immersion and drying system, a flexibility detection system, and a counting and shearing device; the chain plates and chain shafts are assembled into a plate chain through the plate chain assembly system, and the plate chain is detected by the missing part detection system to check whether there are missing parts. Its detection method is to detect each layer of chain plates through multiple magnetic sensors. Since the chain plates are relatively thin and the heights of the chain plates are different, it is easy to have inaccurate detection and cause missing detection problems; the live joint stretching system is to straighten the assembled plate chain, but only performs linear stretching and cannot perform bending stretching, and the flexibility after stretching is not ideal enough, resulting in the inability to meet the bending degree requirements of small-diameter gears; the existing technology generally judges the flexibility of the plate chain by manually observing the sag freedom degree of the arc running of the plate chain, which is difficult to master and is prone to missing detection, misdetection and other phenomena, so that the product quality of the plate chain is difficult to control and cannot meet the requirements of high-grade plate chains at home and abroad.

[0036] The counting and shearing device includes a magnetic induction counting sensor, a plate chain shearing machine, a counting and shearing device controller, a plate chain, and a workbench G; the magnetic induction counting sensor, the plate chain shearing machine, and the counting and shearing device controller are successively installed on the workbench G from left to right; the plate chain first detects and compares the preset shearing amount and the actual number of links through the magnetic induction counting sensor, and then the plate chain is sheared by the plate chain shearing machine. The sheared plate chain freely hangs down below the workbench G. The shearing principle of the plate chain shearing machine is to push out the chain shaft from the chain plate through a telescopic cylinder and a push rod, thereby interrupting the plate chain.

[0037] The counting and shearing device includes: a sensor connecting plate, a left magnetic induction column, a right magnetic induction column, a magnetic core, and a coil B; the left end of the sensor connecting plate is connected with the left magnetic induction column; the right end of the sensor connecting plate is connected with the right magnetic induction column; a cylindrical magnetic core corresponding to the chain shaft is installed in the right magnetic induction column, and a coil B with a certain number of turns is wound around the magnetic core.

[0038] When the counting plate chain passes between the left magnetic induction column and the right magnetic induction column, when the magnetic core detects the magnetic induction signal generated by the chain shaft, it is converted into an electrical signal through the coil B and outputs to count that one more link is added to the plate chain.

[0039] The technological steps of producing a plate chain by adopting the above plate chain production process system:

[0040] Step 1: The single-link plate assembler A feeds the link plates into the plate chain guide rail, and the link plate pusher pushes the link plates to the right. When the link plates pass through the link shaft assembler, they are positioned by the link plate assembly positioner in the plate chain guide rail under the link shaft assembler. At the same time, the link shaft assembler inserts link shafts into the link plates. The assembled link plate and link shaft assembly are continuously pushed to the right once by the subsequent link plate pusher. When the link plate and link shaft assembly pass through the double-link plate assembler A, they are positioned by the link plate assembly positioner in the plate chain guide rail under the double-link plate assembler A. At the same time, the double-link plate assembler A inserts two link plates onto the link shaft. The link plate and link shaft assembly advancing in the plate chain guide rail advances to the right through the single-link plate assembler B, the double-link plate assembler B, and the single-link plate assembler C. While being positioned, they are respectively equipped with link plates by the single-link plate assembler B, the double-link plate assembler B, and the single-link plate assembler C, and are jointly connected into a plate chain and continuously advance to the right. When the plate chain in the plate chain guide rail passes through the link shaft riveting machine, the link shafts are respectively riveted by the link shaft riveting machine, so that the link plates and the link shafts are locked into non-detachable movable joints, and a plate chain is continuously generated to the right.

[0041] Step 2: The plate chain is guided from left to right through the plate chain guide pulley A and the plate chain guide pulley B in sequence. The single-link plate missing part detection device detects whether there is a missing single-link plate in the plate chain, and at the same time transmits the missing part signal to the missing part detection system controller. The double-link plate missing part detection device detects whether there is a missing double-link plate in the plate chain, and at the same time transmits the missing part signal to the missing part detection system controller.

[0042] The infrared detection principle for missing single-link plates: The infrared emitter A emits infrared rays to the 45° refraction surface A of the infrared reflector; the 45° refraction surface A reflects the infrared rays to the 45° refraction surface B, and the refraction surface B reflects the infrared rays to the infrared receiver A for reception. When the plate chain passes through the infrared reflector, if the three layers of single-link plates in the plate chain are not missing, the infrared rays emitted by the three infrared emitters A are blocked by the three layers of link plates, and the infrared receiver A cannot receive the infrared signal emitted by the infrared emitter A. This state is used as a condition for the missing part detection system controller to determine that the three layers of single-link plates are not missing. When the infrared rays emitted by the three infrared emitters A are not blocked by the link plates and are received by the infrared receiver A, this state is used as a condition for the missing part detection system controller to determine that there is a missing part fault in the three layers of single-link plates. That is, the missing part detection system controller determines whether there is a missing part fault in the three layers of single-link plates according to whether the infrared receiver A receives the infrared signal emitted by the infrared emitter A. Once a missing part fault is found in the three layers of single-link plates, an alarm signal is sent and the plate chain assembly system, the missing part detection system, the S-shaped multi-directional bending movable joint stretching system, the oil immersion drying system, the bidirectional flexibility detection system, and the counting joint shearing device of the plate chain production process are suspended. After the missing part fault is eliminated, each system restarts to work.

[0043] The magnetic induction detection principle of the double-chain plate missing part: The U-shaped inductive double-chain plate inductor detects the passing of the front chain plate to generate a magnetic induction signal, and the coil A converts the magnetic induction signal into an electrical signal for output; when the chain plate passes between the high-position magnetic induction seat and the low-position magnetic induction seat, when the two-layer U-shaped inductive double-chain plate inductor detects the double-layer chain plate to generate a magnetic induction signal and is converted into an electrical signal for output by the coil A, the plate chain is complete; when the two-layer U-shaped inductive double-chain plate inductor does not detect the double-layer chain plate and does not generate a magnetic induction signal, and the coil A has no electrical signal output, the plate chain is missing a part.

[0044] Step 3: The synchronous drive device drives the stretching synchronous gear A to turn and feed the plate chain into the S-shaped bending and stretching device, and at the same time drives the stretching synchronous gear B to turn and convey the plate chain to the subsequent section; the plate chain is subjected to multi-directional bending and knuckle stretching through the S-shaped bending and stretching device; the fixed pulley C of the plate chain turns the plate chain to the stretching synchronous gear B.

[0045] The pulling rope is pulled by gravity, the rotating tray is stressed and rotates clockwise, and at the same time drives the plate chain pulley A and the plate chain pulley B to move to both sides; when a weight plate of a certain weight is hung on the weight rack, the pulling rope is pulled through the rope shaft connector B, and the pulling rope is converted into a horizontal pulling force by gravity through the pulley, and drives the rotating tray to rotate clockwise through the shaft connector A and the pulley shaft A. The plate chain pulley A and the plate chain pulley B move to both sides respectively under the drive of the rotating tray, and the distance between the two pulleys becomes larger.

[0046] Step 4: The plate chain enters the oil sump from the oil sump inlet at the upper end of the left wall of the oil sump, freely hangs down 15° from the oil sump inlet to the fixed pulley A, the plate chain is flipped forward 30° and offset downward 45° through the fixed pulley A, the plate chain is flipped forward 30° again and offset downward 30° through the fixed pulley B, and the plate chain is flipped forward 30° again through the fixed pulley C. After the plate chain is fully immersed in oil in the oil sump, it is turned upward by the fixed pulley C and enters the hot air drying device for drying.

[0047] Step 5: The gear synchronizer drives the detection synchronous gear B to rotate clockwise, and at the same time drives the driven gear to lift the plate chain to a predetermined position. The plate chain freely arcs and hangs down from the detection synchronous gear B, and the flexibility of the plate chain is detected when passing through the flexibility detection sensor B. After being re-lifted by the detection synchronous gear A, it freely arcs and hangs down again, and the flexibility of the plate chain is detected again when passing through the flexibility detection sensor A. After being re-lifted by the synchronous forward rotation gear D, it freely hangs down again, and the fixed pulley D rotates the hanging plate chain 90° and places it flat on the tabletop of the workbench F.

[0048] The principle of flexibility detection using infrared rays: The plate chain hangs down between the sector detection plate A and the sector detection plate B; when the three infrared emitting tubes B emit infrared rays and are received by the installed infrared receiving tube B, the flexibility is qualified; when the infrared rays emitted by the three infrared emitting tubes B are blocked by the plate chain and the infrared receiving tube B cannot receive them, the flexibility is unqualified.

[0049] Step 6: The plate chain first passes through the magnetic induction joint sensor to detect and compare the preset shearing amount and the actual number of joints, and then the plate chain is sheared by the plate chain shearing machine. After shearing, the plate chain freely hangs down under the workbench G.

[0050] The prominent beneficial effects of the present invention are as follows: The single-chain link missing part detection device and the double-chain link missing part detection device can be used to conduct hierarchical and classified detection on the plate chain, solving the problems of low detection sensitivity and large error in detecting each layer of chain links by magnetic induction in the existing plate chain production; the S-shaped multi-directional bending and flexible joint stretching system can perform multi-directional stretching on the plate chain, improving the bending flexibility and solving the problem that in the existing technology, only linear stretching is performed on the plate chain, resulting in insufficient bending flexibility of the plate chain and unable to meet the practical requirements of small-diameter gears; the two-way flexibility detection system can automatically detect the forward and reverse flexibility of the plate chain, solving the technical problem that in the existing technology, manual visual inspection is prone to missed inspection and misjudgment, resulting in unstable product quality of the plate chain; the detection is accurate, making the product quality of the plate chain stable, reducing production costs, and having high production efficiency; improving the flexibility of the plate chain, enhancing the product quality of the plate chain, having a long service life, being beneficial to the stable operation of the equipment used, and bringing immeasurable beneficial effects to production enterprises and users.

Once it is found that the double - chain - piece (702) has a missing - part fault, an alarm signal is sent and the plate - type chain assembly system (1), the missing - part detection system (2), the S - shaped multi - directional bending and live - joint stretching system (3), the oil - immersion drying system (4), the two - way flexibility detection system (5), and the joint - counting shearing device (6) of the plate - type chain production process are paused.

[0112] The synchronous driving device (3-4) drives the stretching synchronous gear A (3-1) to turn and feed the plate chain (700) into the S-shaped bending and stretching device (3-2), and at the same time drives the stretching synchronous gear B (3-6) to turn and convey the plate chain (700) to the subsequent part; the plate chain (700) is subjected to multi-directional bending joint stretching through the S-shaped bending and stretching device (3-2); the plate chain fixed pulley C (3-3) turns the plate chain (700) to the stretching synchronous gear B (3-6).
