[0033] Working principle: When cutting the wiring harness of an automobile, multiple wiring harnesses are passed through the openings of the wiring harness plate 1 2 and the wiring harness plate 2 3. When cutting the wiring harness, the cutting assembly 6 is started to force the cutting assembly 6 to move downward, so that the cutting assembly 6 drives the transmission assembly 8 and the support assembly 7 to move downward, so that the transmission assembly 8 drives the wiring harness plate 1 2 and the wiring harness plate 2 3 to approach each other, until the wiring harness plate 1 2 is aligned with the wiring harness plate 2 3, and the incision 4 corresponds to the cutting assembly 6, at which time the transmission assembly 8 is separated; the cutting assembly 6 continues to move downward, forcing the cutting assembly 6 to drive the transmission assembly 8 to continue to move downward, forcing the transmission assembly 8 to drive the resistance assembly 12 to move downward until it contacts the extrusion assembly 10, forcing the resistance assembly 12 to The extrusion component 10 forms an extrusion, so that the extrusion component 10 drives the clamping component 9 to move, forcing the clamping component 9 to clamp the wire harness, and at the same time forcing the cutting component 6 to drive the supporting component 7 to continue to move downward until the supporting component 7 contacts the wire harness plate 1 2 and the wire harness plate 2 3, and the switch component 13 is turned on, forcing the heat treatment component 14 to turn on the power and heat the wire harness cutting position; when cutting the wire, the cutting component 6 continues to move downward, so that the cutting component 6 cuts the wire harness, at this time the supporting component 7 and the switch component 13 are compressed to cooperate with the cutting movement of the cutting component 6; after the wire harness is cut, when the rubber jacket is peeled off the head of the wire harness, the heat treatment component 14 softens the wire harness The head of the wire harness is clamped together, forcing the tangent component 6 to retreat.

[0044] Working principle: When cutting the wiring harness of the automobile, multiple wiring harnesses are passed through the openings of the wiring harness plate 1 2 and the wiring harness plate 2 3, so that the tangent position of the wiring harness is located at the incision 4. When cutting, the hydraulic lifting rod 601 is started, and the hydraulic lifting rod 601 drives the mounting plate 602 to move down, and the mounting plate 602 drives the cutting knife 603 and the support assembly 7 to move down, and the support assembly 7 drives the arc heating plate 1402 to move down, and the mounting plate 602 drives the connecting rod 1 801 and the vertical spur rack 802 and the switch assembly 13 to move down;

[0045] When the connecting rod 1 801 drives the vertical spur rack 802 to move downward to mesh with the transmission gear 803, the vertical spur rack 802 moves downward to drive the transmission gear 803 to rotate, and the transmission gear 803 drives the horizontal spur rack 805 to move horizontally, forcing the horizontal spur rack 805 to drive the connecting rod 2 804 to move, forcing the connecting rod 2 804 to drive the wiring harness plate 1 2 and the wiring harness plate 2 3 to approach each other, until the wiring harness plate 1 2 and the wiring harness plate 2 3 are in contact and aligned, so that the incision 4 is located below the cutting knife 603, and at this time, the vertical spur rack 802 is separated from the friction hybrid gear;

[0046] The hydraulic lifting rod 601 continues to move downward, forcing the mounting plate 602 to drive the connecting rod 1 801 to move downward, so that the connecting rod 1 801 drives the abutting rod 1201 and the contact block 1202 to move downward, until the contact block 1202 drives the baffle plate 1004 to move downward, and the baffle plate 1004 drives the connecting plate 903 and the extrusion rod 1003 to move downward synchronously, and the connecting plate 903 forces the clamping rod 901 to drive the clamping block 902 to move downward, until the clamping block 902 clamps the wiring harness, and the clamping spring 904 is compressed, at which time the extrusion rod 1003 moves downward to drive the extrusion piston 1002 to push the extrusion cylinder 1001, forcing the gas in the extrusion cylinder 1001 to enter the delay cylinder 1101 through the air guide pipe 1103;

When the baffle 1004 drives the connecting plate 903 and the extrusion rod 1003 to move downward synchronously, the static contact 1301 generates a force on the moving contact 1306, so that the moving contact 1306 drives the guide rod 1303 to move on the insulating plate 1302.

At this time, the clamping block 902 does not completely clamp the wire harness;

[0048] When cutting the wire, the hydraulic lifting rod 601 continues to move downward, and under the action of the incision 4, the cutting knife 603 is forced to cut the wire harness. At this time, the contact block 1202 drives the baffle 1004 to continue to move downward, and the clamping block 902 completely clamps the wire harness. The limit spring 1305, the support spring 703 and the clamping spring 904 are all at the maximum limit to cooperate with the cutting knife 603 to cut the wire harness;

[0049] After the wire harness is cut, when the rubber jacket on the head of the wire harness is peeled off, the electrical stripping sheet 1401 softens the lower head of the wire harness, and the arc-shaped heating sheet 1402 softens the upper head of the wire harness, and a bayonet is formed between the electrical stripping sheets 1401. When the wire harness is softened, the electrical stripping sheet 1401 is forced to be connected with the wire harness, and the hydraulic lifting rod 601 retreats. During the retreat, the cutting knife 603 separates from the incision 4, and the supporting spring 703 retreats, so that the inner rod 701 and the outer rod 702 move to their original positions, and the limit spring 1305 returns to its original position, forcing the moving contact 1306 to separate from the static contact 1301, disconnecting the electrical stripping sheet 14 01 circuit, so that the electrical stripping sheet 1401 and the wiring harness are connected together, and the contact block 1202 is separated from the baffle 1004. Due to the effect of the one-way valve, the gas can only enter the extrusion cylinder 1001 from the delay cylinder 1101 through the delay air pipe 1102. Similarly, the gas can only enter the delay cylinder 1101 from the extrusion cylinder 1001 through the air pipe 1103, and the diameter of the delay air pipe 1102 is much smaller than that of the air pipe 1103. When the extrusion piston 1002 releases the pressure, the gas in the delay cylinder 1101 slowly enters the extrusion cylinder 1001, forming a delayed retreat effect of the extrusion piston 1002.

[0050] Due to the delayed retreat of the extrusion piston 1002, the clamping block 902 is forced to still clamp the wiring harness, but at this time the hydraulic lifting rod 601 continues to retreat, forcing the mounting plate 602 to drive the connecting rod 801 to retreat, until the connecting rod 801 drives the vertical spur rack 802 to move upward, and under the action of the transmission gear 803, the horizontal spur rack 805 is forced to move in the opposite direction, forcing the wiring harness plate 12 and the wiring harness plate 23 to separate. Since the electrical stripping sheet 1401 is clamped together with the wiring harness and the clamping block 902 still clamps the wiring harness, when the wiring harness plate 12 and the wiring harness plate 23 are separated, under the action of horizontal pulling force, since the electrical stripping sheet 1401 is located between the incision 4 and the wiring harness plate 12, the electrical stripping sheet 1401 on the wiring harness plate 23 is forced to strip off the rubber jacket of the wiring harness on the wiring harness plate 2, and the hydraulic lifting rod 601 retreats to its original position to complete the stripping action of the rubber jacket.

[0051] The setting of the cutting component 6 can realize the cutting function of the wire harness, and at the same time provide power to make the transmission component 8 move, realize the clamping and cutting functions in the downward movement process, and realize the stripping function of the rubber outer skin of the wire harness in the retraction process; the setting of the support component 7 can avoid the direct contact between the mounting plate 602 and the wire harness plate 1 2 and the wire harness plate 2 3, thereby improving the protection capability, and at the same time, in the downward movement and cutting process of the cutting knife 603, it can realize the contraction capability, which is convenient for the cutting knife 603 to cut the wire harness, thereby improving the rationality; the setting of the clamping component 9 can realize the clamping effect on the wire harness, which is convenient for the wire harness The wire harness can be cut, and at the same time, the wire harness plate 2 3 can strip the rubber jacket of the wire harness head during the retraction process; the setting of the transmission component 8 can realize the approach or distance between the wire harness plate 1 2 and the wire harness plate 2 3, and on the other hand, it can realize the effect on the resistance component 12, so that the extrusion component 10 and the clamping component 9 can have subsequent movement, which is convenient for clamping the wire harness and improves rationality; the setting of the extrusion component 10 can realize the force on the clamping component 9, so that the clamping component 9 clamps the wire harness, and at the same time, the extrusion component 10 introduces the gas into the delay component 11, so that during the retraction process, The gas is compressed and delayed into the extrusion cylinder 1001, so that when the transmission component 8 is meshing, the clamping component 9 can still clamp the wire harness, thereby facilitating the stripping of the rubber jacket on the head of the wire harness; the setting of the delay component 11 can utilize the control of the inlet and outlet of the gas to control the retreat of the extrusion component 10, realize the effect of the extrusion component 10 on the clamping component 9, so that the clamping component 9 delays the release of the wire harness, and improves the control ability of the device; the setting of the resistance component 12 can transmit the force of the transmission component 8, so that the contact block 1202 contacts the baffle 1004, thereby realizing the extrusion component The control function of component 10 enables the clamping component 9 to clamp the wire harness after the wire harness plate 1 2 and the wire harness plate 2 3 move; the setting of the switch component 13 can realize the control function of the heat treatment component 14 during the cutting process, so that the heat treatment component 14 has a heating treatment effect when the cutting knife 603 cuts the wire harness, which is beneficial to saving energy and improving the rationality of the device; the setting of the heat treatment component 14 can heat the rubber jacket of the wire harness head, so that the rubber jacket softens, which is convenient for cutting the wire harness and facilitating the stripping of the rubber jacket of the wire harness head after cutting by the wire harness plate 2 3.

[0052] When processing automobile wiring harnesses, this solution, on the one hand, completes the process of cutting and clamping the wiring harness during the downward movement of the cutting knife 603 and the mounting plate 602, and on the other hand, smoothly completes the action of stripping the outer jacket of the wiring harness head during the retraction of the cutting knife 603, thereby achieving the effect of automatic cutting and automatic stripping of the wires. There is no need to process the wiring harnesses for the second time, so that the processes can be connected, time is saved, and the processing of the wiring harnesses is facilitated, the continuous processing of the wiring harnesses is realized, the automation and intelligence of the device are improved, the processing efficiency of the wiring harnesses is improved, the maintenance cost of the enterprise is reduced, and the market competitiveness of the enterprise is improved.
