Description

Technical Field

[0001] The present invention relates to the technical field of wire harness pressing iron hoops, and particularly to a pressing iron hoop device for a high-voltage wire harness assembly. Background Art

[0002] A high-voltage wire harness is a collection of wires used to transmit high-voltage electricity and signals, mainly composed of a conductor, an insulating layer, a shielding layer, a sheath, etc. It mostly uses high-purity oxygen-free copper material and is processed into a wire harness through a special stranding process to reduce resistance and reduce power loss during the power transmission process. High-voltage wire harnesses have extremely high requirements for insulation performance and usually adopt a multi-layer composite structure to improve the insulation strength and withstand voltage level. In the prior art, the method of using a pressing iron hoop is usually adopted to fix the cable and the insulating layer to each other, so that the insulating layer can protect the cable. The pressing iron hoop device uses riveting technology to firmly fix the iron hoop to the wire harness through a pressing die, playing a good fixing role; Existing pressing iron hoop devices have gradually replaced traditional manual operations through automated machinery, reducing the situation of personnel injuries and improving work efficiency. Existing high-voltage wire harnesses also come in various diameters, and the diameters of high-voltage wire harnesses used in different scenarios or fields often vary. Existing pressing iron hoop devices cannot automatically switch the pressing die according to the diameter of the high-voltage wire harness, resulting in the need to manually replace the die or use a device of the corresponding size before pressing the iron hoop. This process is rather cumbersome, and there are certain errors in manual selection. When there is an error between the die and the actual size of the wire harness, it may cause the iron hoop to be fixed unstably, resulting in the insulating layer being unable to play a good insulation performance, affecting the use of the high-voltage wire harness and possibly bringing a series of safety hazards. For this reason, we propose a pressing iron hoop device for a high-voltage wire harness assembly. Summary of the Invention

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The present invention uses rollers to detect the diameter of the wire harness, and enables two sliding members to slide in opposite directions according to the diameter of the wire harness. The sliding members will drive the upper fixing plates thereon to move synchronously. The fixing plates will pull one end of the connecting rope, and the other end of the connecting rope will pull the winding shaft to rotate. When the winding shaft rotates, it will drive the rotating shaft and the die plate to rotate synchronously. According to the diameter of the wire harness, the die plate will rotate by different amplitudes, and the die groove corresponding to the diameter of the wire harness on the die plate will rotate to the due upper position, and it can automatically adjust to a suitable iron hoop pressing die according to the wire harness diameter.

[0015] 2. The present invention uses the first cylinder to push the limiting frame to drive the corresponding magnetic shafts and roller shafts to move towards the die plate. Initially, the magnetic shafts are all located in the separation grooves. The two roller shafts are far apart, will not contact the wire harness, and do not hinder the movement of the wire harness towards the die plate. When the limiting frame moves towards the die plate, the two magnetic shafts will move relatively due to magnetic attraction, and the two roller shafts will clamp the wire harness in the guiding groove, and will straighten the wire harness as the magnetic shafts continue to move, preventing the wire harness from bending and affecting the precision of iron hoop pressing.

[0016] 3. The present invention utilizes the magnetic attraction of the magnetic axis on the slider, causing the magnetic axis to drive the slider and the push rod towards the supporting bracket, and pushing the iron hoop on the supporting bracket into the corresponding mold groove. At the same time, the roller shaft will push the anti-slip plate towards the supporting bracket, and make the positioning rod insert into the corresponding positioning hole on the mold plate to limit the mold plate, preventing the mold plate from rotating during the iron hoop pressing process. Moreover, the anti-slip plate will also prevent the roller shaft from rotating, increasing the friction between the roller shaft and the wire harness, and preventing the end of the wire harness from sliding during the iron hoop pressing process.

[0017] 4. The present invention utilizes the contact between the push plate and the corresponding baffle to push the sliding seat to slide within the slide rail. The balls on both sides of the sliding seat will move from the bottom of the corresponding arc groove into the next arc groove, and stop after rolling to the bottom, causing the sliding seat to move forward a specified distance. When the next mold groove of the mold plate rotates to directly above, the corresponding pressing part can slide above the mold groove, making the mold groove always correspond to the pressing part.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-9 , the present invention provides a technical solution: a pressing iron hoop device for a high-voltage wire harness assembly, including an operating table 1, a fixed seat 2 fixedly installed on the operating table 1, four sliding members 3 symmetrically and slidably installed in the fixed seat 2, and a plurality of telescopic rods 4 fixedly connected between each sliding member 3 and the inner wall of the fixed seat 2. Each telescopic rod 4 is an elastic and automatically telescopic rod member. A plurality of electric shafts 5 are rotatably installed on each sliding member 3, and a roller 6 for limiting the wire harness is fixedly installed on each electric shaft 5. A rotating shaft 11 is rotatably installed in the fixed seat 2, a die plate 8 is fixedly installed on the rotating shaft 11, and a plurality of die grooves 9 for pressing the iron hoop are arranged on the die plate 8. The die grooves 9 are arranged in a ring according to the size. In the initial state, the die groove 9 with the smallest size is located directly above, and in the opposite direction of the rotation of the rotating shaft 11, the size of the die groove 9 gradually increases. Both ends of the rotating shaft 11 are fixedly installed with wire winding shafts 12, and a torsion spring 14 is fixedly connected between each wire winding shaft 12 and the inner wall of the fixed seat 2. One end of each sliding member 3 is fixedly installed with a fixing plate 15, and a connecting rope 13 is fixedly installed on one side of each fixing plate 15. One end of each connecting rope 13 is wound and fixedly installed on the corresponding wire winding shaft 12. Two guiding grooves 7 for guiding the wire harness are symmetrically arranged on the fixed seat 2, and each guiding groove 7 is located between the corresponding rollers 6, as shown in the appendix Figure 3As shown in the figure, insert the high-voltage wire harness into the corresponding position between two rollers 6 at one end of the fixed seat 2. The corresponding four rollers 6 will slide according to the diameter of the wire harness, and the corresponding two sliding members 3 will slide in opposite directions. The sliding member 3 will drive the upper fixing plate 15 thereon to move synchronously. The fixing plate 15 will pull one end of the connecting rope 13, and the other end of the connecting rope 13 will pull the winding shaft 12 to rotate. When the winding shaft 12 rotates, it will drive the rotating shaft 11 and the mold plate 8 to rotate synchronously. The mold plate 8 will rotate by different amplitudes according to the diameter of the wire harness, and the mold groove 9 corresponding to the diameter of the wire harness on the mold plate 8 will rotate to the due north. It can automatically adjust to a suitable iron hoop pressing mold according to the wire harness diameter. Then, the electric shafts 5 at the corresponding one end on the fixed seat 2 will drive the rollers 6 to rotate and convey the wire harness. One end of the wire harness will move along the guide groove 7 after passing through the rollers 6 and pass through the corresponding mold groove 9 in the mold plate 8. By controlling the number of rotation turns of the electric shaft 5, the end of the wire harness will move to a suitable position for pressing the iron hoop.

[0022] On both sides of the mold plate 8, there are support brackets 16 for placing iron hoops. Each support bracket 16 is fixedly installed on the fixed seat 2. Two clamping plates 29 for clamping the iron hoops are slidably installed in each support bracket 16. A number of elastic rods 28 are fixedly connected between each clamping plate 29 and the corresponding support bracket 16. Two first cylinders 20 are symmetrically and fixedly installed on the fixed seat 2. The output end of each first cylinder 20 is fixedly installed with a limit frame 22. Two magnetically attracted magnetic shafts 21 are slidably installed in each limit frame 22. Two roller shafts 25 for straightening the wire harness are rotatably installed on each magnetic shaft 21. A number of chutes 24 for limiting the magnetic shafts 21 are arranged on the fixed seat 2. The chutes 24 are arranged horizontally and their width is greater than the diameter of the magnetic shafts 21. One end of each chute 24 communicates with a separation groove 23. Each separation groove 23 is arranged obliquely. Two positioning rods 17 are slidably installed on each support bracket 16. A number of positioning holes 10 for limiting the positioning rods 17 are arranged in a circular pattern on the mold plate 8. One end of each positioning rod 17 is fixedly installed with an anti-slip plate 18 for preventing the roller shaft 25 from rotating. A spring 19 is fixedly connected between one side of each anti-slip plate 18 and the corresponding support bracket 16. Two sliders 26 attracted by the magnetic force of the magnetic shafts 21 are symmetrically and slidably installed on the fixed seat 2. One end of each slider 26 is fixedly installed with a push rod 27 for pushing the iron hoop on the support bracket 16. Before placing the wire harness, first select two suitable iron hoops and place them vertically on the two support brackets 16 respectively. The two clamping plates 29 in the support bracket 16 will clamp the iron hoop, and the elastic rods 28 will also be compressed correspondingly to fix the iron hoop to the support bracket 16. The wire harness can pass through the iron hoop during the movement process. After one end of the wire harness completes the movement, the first cylinder 20 at the inserted end of the wire harness will extend and push the limit frame 22 to drive the corresponding magnetic shaft 21 and roller shaft 25 to move towards the mold plate 8, as shown in the appendix Figure 6As shown, the magnetic axes 21 are initially located in the separation grooves 23. The two roller shafts 25 are relatively far apart and will not contact the wire harness, nor will they hinder the movement of the wire harness towards the mold plate 8. When the limit frame 22 moves towards the mold plate 8, the two magnetic axes 21 will move relative to each other due to magnetic attraction, and the two roller shafts 25 will clamp the wire harness in the guide groove 7. As the magnetic axes 21 continue to move, the wire harness will be straightened, preventing the wire harness from bending and affecting the accuracy of pressing the iron hoop. Moreover, since the width of the sliding groove 24 is greater than the diameter of the magnetic axis 21, the magnetic axis 21 can slide in the limit frame 22 according to the width of the wire harness, and can achieve a good straightening effect on wire harnesses of different diameters. When the magnetic axis 21 is about to move to the end of the sliding groove 24, the magnetic axis 21 will move to a position parallel to the slider 26, and the roller shaft 25 will contact the anti-slip plate 18. As the magnetic axis 21 continues to move, it will drive the slider 26 and the push rod 27 towards the support bracket 16, and push the iron hoop on the support bracket 16 into the corresponding mold groove 9. At the same time, the roller shaft 25 will push the anti-slip plate 18 towards the support bracket 16, and make the positioning rod 17 insert into the corresponding positioning hole 10 on the mold plate 8 to limit the mold plate 8 and prevent the mold plate 8 from rotating during the process of pressing the iron hoop. Moreover, the anti-slip plate 18 will also prevent the roller shaft 25 from rotating, and the friction between the roller shaft 25 and the wire harness will increase, preventing the end of the wire harness from sliding during the process of pressing the iron hoop.

[0023] A fixing frame 30 is fixedly installed on the fixing seat 2. A number of pressing parts 37 matching the mold grooves 9 are arranged on the fixing frame 30. The pressing parts 37 are located above the mold plate 8 and correspond to the mold grooves 9 one by one. A second air cylinder 31 for pushing the pressing parts 37 is fixedly installed on the fixing frame 30. A slide rail 33 is arranged on the fixing frame 30. A sliding seat 34 is slidably installed in the slide rail 33. A number of continuous arc grooves 36 are arranged on both inner walls of the slide rail 33. A number of balls 35 matching the arc grooves 36 are arranged on both sides of the sliding seat 34. Each pressing part 37 is slidably installed in the sliding seat 34 and is arranged horizontally according to the size. In the initial state, the pressing part 37 with the smallest size is located above the mold groove 9 with the smallest size, and in the opposite direction of the sliding of the sliding seat 34, the size of the pressing part 37 gradually increases. A number of magnetic strips 38 for magnetically attracting the pressing parts 37 are fixedly installed in the sliding seat 34. The magnetic strips 38 correspond to the pressing parts 37 one by one. A magnetic plate 32 is fixedly installed at the output end of the second air cylinder 31. A clamping groove 39 corresponding to the magnetic plate 32 is arranged at the upper end of each pressing part 37. A number of through holes 42 are arranged on the sliding seat 34. The through holes 42 correspond to the clamping grooves 39 one by one and are located above the corresponding clamping grooves 39. A number of baffle plates 40 are fixedly installed on the sliding seat 34. A number of push plates 41 are fixedly installed on the mold plate 8. The push plates 41 are arranged in a circular pattern and correspond to the baffle plates 40 one by one. Each baffle plate 40 is located on the movement track of the corresponding push plate 41. During the rotation of the mold plate 8, as shown in the appendix Figure 9As shown, the ejector plate 41 on the mold plate 8 will contact the corresponding baffle 40 on the sliding seat 34. As the mold plate 8 rotates, it will push the sliding seat 34 to slide within the slide rail 33. The balls 35 on both sides of the sliding seat 34 will move from the bottom of the corresponding arc groove 36 to the next arc groove 36. After the balls 35 move into the next arc groove 36, they will roll to its bottom and stop. At this time, the ejector plate 41 will no longer contact the baffle 40. When each ejector plate 41 contacts the corresponding baffle 40, it will push the sliding seat 34 forward by a specified distance, so that when the next mold groove 9 of the mold plate 8 rotates to directly above, the corresponding pressing member 37 can slide above the mold groove 9. The size of the mold groove 9 is proportional to the rotation angle of the rotating shaft 11, and the size of the pressing member 37 is proportional to the sliding distance of the sliding seat 34. At the same time, the rotation angle of the rotating shaft 11 is also proportional to the sliding distance of the sliding seat 34, so that the mold groove 9 always corresponds to the pressing member 37 of the same size. After the first cylinder 20 extends completely, the mold plate 8 and the wire harness are fixed. At this time, the second cylinder 31 will extend, and the magnetic plate 32 at its end will pass through the corresponding through hole 42 and insert into the card slot 39 at the upper end of the corresponding pressing member 37. As the second cylinder 31 continues to extend, the corresponding pressing member 37 will be separated from the magnetic attraction of the magnetic strip 38, while the other pressing members 37 will continue to be attracted by the magnetic force of the magnetic strip 38 and remain in the sliding seat 34. After the pressing member 37 enters the corresponding mold groove 9 downward, it will rivet the iron hoop to the wire harness to fix the wire harness to the insulating layer. Then the second cylinder 31 will retract, driving the magnetic plate 32 and the pressing member 37 to retract. When the pressing member 37 enters the sliding seat 34, it is attracted by the magnetic force of the magnetic strip 38 and resets.

[0024] Specifically, first, select two suitable iron hoops and place them vertically on two supporting brackets 16 respectively. Then, insert the high-voltage wire harness into the corresponding position between two rollers 6 at one end of the fixed seat 2. The corresponding four rollers 6 will slide according to the diameter of the wire harness, and the corresponding two sliding members 3 will slide in the opposite direction. The sliding member 3 will drive the upper fixing plate 15 thereon to move synchronously. The fixing plate 15 will pull one end of the connecting rope 13, and the other end of the connecting rope 13 will pull the wire winding shaft 12 to rotate. When the wire winding shaft 12 rotates, it will drive the rotating shaft 11 and the mold plate 8 to rotate synchronously, so that the mold groove 9 corresponding to the diameter of the wire harness on the mold plate 8 rotates to the directly above. Then, the electric shafts 5 at the corresponding end on the fixed seat 2 will drive the rollers 6 to rotate and convey the wire harness. The wire harness passes through the iron hoop during the movement and passes through the corresponding mold groove 9 in the mold plate 8 until it reaches the appropriate position for pressing the iron hoop. During the rotation of the mold plate 8, the push plate 41 on the mold plate 8 will contact the corresponding baffle 40 on the sliding seat 34, and as the mold plate 8 rotates, it will push the sliding seat 34 to slide in the slide rail 33. The ball bearings 35 on both sides of the sliding seat 34 will move from the bottom of the corresponding arc groove 36 to the next arc groove 36. After the ball bearings 35 roll to its bottom, they will stop. The sliding seat 34 moves forward a specified distance, so that the mold groove 9 always corresponds to the lower pressing member 37. At this time, the first cylinder 20 at the inserted end of the wire harness will extend, and push the limiting frame 22 to drive the corresponding magnetic shaft 21 and the roller shaft 25 to move towards the mold plate 8. When the limiting frame 22 moves towards the mold plate 8, the two magnetic shafts 21 will move relatively due to magnetic attraction, and the two roller shafts 25 will clamp the wire harness in the guide groove 7, and straighten the wire harness as the magnetic shaft 21 continues to move. When the magnetic shaft 21 is about to move to the end of the chute 24, the magnetic shaft 21 will move to a position parallel to the slider 26, and the roller shaft 25 will contact the anti-slip plate 18. As the magnetic shaft 21 continues to move, it will drive the slider 26 and the push rod 27 to move towards the supporting bracket 16, and push the iron hoop on the supporting bracket 16 into the corresponding mold groove 9. At the same time, the roller shaft 25 will push the anti-slip plate 18 towards the supporting bracket 16, and make the positioning rod 17 insert into the corresponding positioning hole 10 on the mold plate 8 to limit the mold plate 8, and the anti-slip plate 18 will also prevent the roller shaft 25 from rotating, preventing the end of the wire harness from sliding during the process of pressing the iron hoop. Finally, the second cylinder 31 will extend, and the magnetic plate 32 at its end will pass through the corresponding through hole 42 and insert into the clamping groove 39 at the upper end of the corresponding lower pressing member 37. As the second cylinder 31 continues to extend, the corresponding lower pressing member 37 will be separated from the magnetic attraction of the magnetic strip 38, while the other lower pressing members 37 will continue to be attracted by the magnetic force of the magnetic strip 38 and remain in the sliding seat 34. After the lower pressing member 37 moves down into the corresponding mold groove 9, it will rivet the iron hoop to the wire harness to fix the wire harness and the insulating layer. Then, the second cylinder 31 will retract, driving the magnetic plate 32 and the lower pressing member 37 to retract. The lower pressing member 37 is attracted by the magnetic force of the magnetic strip 38 and resets when it enters the sliding seat 34. After the iron hoop at one end of the wire harness is pressed, the first cylinder 20 will retract and drive the roller shaft 25 to reset.The wire harness is no longer limited, and at the same time, the slider 26 and the push rod 27 will be driven to reset by the magnetic force of the magnetic shaft 21. Then, the electric shaft 5 will rotate again, press the iron hoop at one end of the wire harness and convey it forward, and clamp it between the rollers 6 at the other end on the fixed seat 2. The die plate 8 will not rotate. Until the other end of the wire harness moves to the die groove 9, the electric shaft 5 will stop rotating, and then the above operation will be repeated to press the iron hoop at the other end of the wire harness.
