Description

Technical Field

[0001] This invention relates to the field of wire harness fixed-length cutting, specifically to a data wire harness equidistant cutting device. Background Technology

[0002] Wire harness cutting equipment can cut power cords, cables and other transmission wire harnesses. During the cutting process, a clamping structure that can move laterally clamps the end of the wire harness, and the wire harness is pulled and moved on the cutting frame by the clamping structure. The length pulled is the length to be cut. Because the wire harness is prone to bending due to gravity during the pulling process (especially the longer the wire harness, the greater the degree of bending), the length of the wire harness after being cut by the cutting structure is too different from the rated length (too long), and the error is too large. If multiple equally spaced wire harnesses need to be cut, the length of each wire harness will be different. Summary of the Invention

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] Example 1: Please refer to Figures 1-8 The figure shows a data cable harness equidistant cutting device, including: a device platform 1 fixedly mounted on the factory ground, a fixed frame 5 fixedly mounted on the upper end face of the device platform 1, and an inclined guide plate 2 fixedly mounted inside the device platform 1. A guide rail 6 is fixedly mounted on the side wall of the fixed frame 5, and a slider 7 is slidably assembled inside the guide rail 6. A driving structure is also provided between the slider 7 and the fixed frame 5. The driving structure is a cylinder push rod or a motor transmission assembly. The fixed part and the telescopic part of the cylinder push rod are fixed to the fixed frame 5 and the slider 7, respectively. The motor transmission assembly includes two transmission gears rotatably mounted outside the fixed frame 5, and a transmission toothed belt is assembled between the two transmission gears. The slider 7 is fixed outside the transmission toothed belt. The front end face of the slider 7 is fixedly mounted with a prior art upper and lower clamping structure. The side wall of the upper and lower clamping structure is distributed with a first clamping plate 21 and a second clamping plate 22 distributed in an upper and lower manner. The upper and lower clamping structure is used to drive the second clamping plate 22 and the first clamping plate 21 to move synchronously in opposite directions.

[0033] It also includes: a wire harness clamping unit, used for clamping and limiting the wire harness that needs to be cut, the wire harness clamping unit is set on the top of the fixing frame 5;

[0034] The wire harness cutting unit is used to cut the wire harness after it has been spaced at a fixed distance. The wire harness cutting unit is located on top of the wire harness clamping unit.

[0035] The support unit is used to support the bottom of the cut wire harness to prevent the wire harness from bending downwards due to its own weight. The support unit is set inside the inclined guide plate 2.

[0036] The wire harness clamping unit includes a cutting frame 9 fixed to the upper end face of the fixing frame 5. The cutting frame 9 has a gantry structure. Two conveying rollers 15 are arranged vertically on the inner side of the cutting frame 9. Both ends of the conveying rollers 15 are rotatably fitted with limit blocks 14. The lower set of limit blocks 14 is fixed inside the cutting frame 9, and the upper set of limit blocks 14 is axially slidably assembled inside the cutting frame 9. The outer surface of the conveying rollers 15 has several arc-shaped grooves 20 that are equidistantly distributed in a straight line. The downwardly distributed arc-shaped grooves 20 can limit the wire harnesses of different thicknesses. A limit component is also provided between the upper conveying rollers 15 and the cutting frame 9.

[0037] The limiting component includes pull rods 16 fixed to the limiting blocks 14 distributed above. The top of each pull rod 16 slides through the cutting frame 9, and the bottom of the pull rod 16 is fixedly provided with a connecting block 17 that slides with the cutting frame 9. The connecting block 17 is located below the limiting block 14. A first tension spring 18 is fixedly provided between the bottom of the connecting block 17 and the cutting frame 9, and a connecting rod 19 is fixedly provided between the tops of the two pull rods 16. The elastic tension applied to the pull rods 16 by the first tension spring 18 can allow the two conveying rollers 15 to elastically clamp and limit the wire harness. Two bolts are threaded on the side wall of the cutting frame 9, and the two bolts abut against the outer wall of the two pull rods 16 respectively. When the wire harness is clamped between the two conveying rollers 15, the bolts are tightened to prevent the pull rods 16 from moving elastically, thereby ensuring the stability of the two conveying rollers 15 in limiting the wire harness.

[0038] The limiting cutting unit includes a knife holder 12 fixed on the side of the cutting frame 9 near the inclined guide plate 2, and a second cutter 13 is mounted on the side wall of the knife holder 12. A cylinder push rod 10 is fixedly mounted on the top of the cutting frame 9, and the output end of the cylinder push rod 10 faces downward. A first cutter 11 is fixedly mounted on the output end of the cylinder push rod 10. The cylinder push rod 10 drives the first cutter 11 to descend and move in contact with the second cutter 13 to cut the wire harness. That is, when the first cutter 11 descends, the blades of the first cutter 11 and the second cutter 13 intersect, thereby enabling the wire harness to be cut.

[0039] There are two second cutters 13, and a clamping space is provided between the second cutter 13 and the cutter holder 12. The clamping ends of the first clamping plate 21 and the second clamping plate 22 are both L-shaped. The clamping space is used for the L-shaped ends of the first clamping plate 21 and the second clamping plate 22 to extend into. The upper end faces of the two second cutters 13 are parallel to the upper end face of the cutter holder 12. The ends of the two second cutters 13 that are far apart from each other are elastically rotated and assembled with the cutter holder 12 by a pin and a torsion spring. The two second cutters 13 are horizontal when not touched. When the ends of the wire harness clamped by the first clamping plate 21 and the second clamping plate 22 move to the right, the L-shaped ends of the first clamping plate 21 or the second clamping plate 22 will elastically pull the two second cutters 13 apart. After the first clamping plate 21 and the second clamping plate 22 are separated from the second cutters 13, the second cutters 13 will elastically return to their original position under the action of the pin and the torsion spring.

[0040] The support unit includes an optical shaft 23 fixedly mounted on the end face of the fixed frame 5 away from the cylinder push rod 10. The inclined guide plate 2 has several first slots 3 distributed in a straight line at equal intervals inside, and a support plate 4 is movably arranged inside each first slot 3. A rotating sleeve 24 is fixedly mounted on the end of the support plate 4 near the fixed frame 5, and the rotating sleeve 24 is rotatably mounted on the outer surface of the optical shaft 23. The support plate 4 has an inclined state and a horizontal state. When the support plate 4 is in the inclined state, the inclined surface of the inclined guide plate 2 is coplanar with the inclined surface of the support plate 4. When the support plate 4 is in the horizontal state, the upper end face of the support plate 4 is parallel to the upper end face of the equipment platform 1. An adjustment component is provided between the slider 7 and the rotating sleeve 24. During the lateral movement of the slider 7, the state of the support plate 4 can be switched by adjusting the component.

[0041] The adjusting component includes an arc-shaped groove 25 formed on the outer surface of the rotating sleeve 24. A curved rod 26 is fixedly mounted on the end of the slider 7 away from the first clamping plate 21 or the second clamping plate 22, and a lever 27 is fixedly mounted on the end of the curved rod 26 away from the slider 7. The axis of the lever 27 intersects perpendicularly with the axis of the optical axis 23. The lever 27 is located on the side of the curved rod 26 closest to the cutting frame 9. The distance between the lever 27 and the cutting frame 9 is 'a', and the distance between the cutting frame 9 and the first clamping plate 21 or the second clamping plate 22 is 'b', where a > b. The fixed frame 5... The inside is provided with a through groove for the support plate 4 to pass through. Magnetic blocks are fixedly embedded between the lower end face of the through groove and the upper end face of the support plate 4. The magnetic poles of the two magnetic blocks are opposite to each other. The inside of the fixing frame 5 is provided with a second empty groove 8 for the curved rod 26 to pass through. Each time the slider 7 moves laterally with the lever 27 and passes through the inside of the arc groove 25, the support plate 4 can switch between two states. If the support plate 4 is in a horizontal state, it can be kept in a horizontal state by the magnetic attraction of the two magnetic blocks.

[0042] The end face of the second cutter 13 away from the cutting frame 9 and the end face of the first cutter 11 close to the cutting frame 9 are the cutting planes. The first cutter 11 is located on the side of the second cutter 13 away from the cutting frame 9, ensuring that after the first cutter 11 moves downward and cuts the wire harness through the second cutter 13, the part of the wire harness that is clamped and pulled is directly above the clamping space.

[0043] Example 2: Please refer to Figures 8-10 This embodiment is a further description of the first embodiment. Each support plate 4 has two symmetrically distributed receiving slots 28 inside. Each receiving slot 28 has a rotating shaft 29 rotatably arranged inside. The outer surface of the rotating shaft 29 is fixedly sleeved with a first gear 31 and a protective plate 30. The two protective plates 30 are also symmetrically distributed. A second gear 35 is rotatably arranged at the bottom of the support plate 4. Two circumferentially distributed racks 32 are distributed on the outside of the second gear 35. The racks 32 are slidably assembled with the support plate 4, and the sliding direction of the racks 32 is parallel to the support plate 4. The racks 32 include a first meshing part 33 and a second meshing part 34. The first meshing part 33 and the second meshing part 34 mesh with the second gear 35 and the first gear 31, respectively. An actuating element is also provided between the support plate 4 and the inclined guide plate 2. Under the action of the actuating element, the protective plate 30 can be adjusted to be in an unfolded or retracted state according to the horizontal or inclined state of the support plate 4.

[0044] The actuating element includes an extension rod 36 fixed to one end of one of the racks 32 near the optical axis 23. A dome rod 38 is fixedly provided at the end of the extension rod 36 near the optical axis 23, pointing vertically upward. A second tension spring 37 is fixed between the end of the dome rod 38 away from the optical axis 23 and the support plate 4. An arc-shaped guide block 39 is provided above each dome rod 38. The arc-shaped guide block 39 is fixed to the side of the fixing frame 5 near the optical axis 23, and the top of the dome rod 38 slides in contact with the arc surface of the arc-shaped guide block 39. When the dome rod 38 deflects with the support plate 4, the arc surface of the arc-shaped guide block 39 restricts the dome rod 38, and the elastic tension applied to the dome rod 38 by the second tension spring 37 allows the dome rod 38 to adaptively change position.

[0045] The top of the dome rod 38 is rounded, which makes it easier for the dome rod 38 to slide between itself and the arc-shaped guide block 39 during the deflection of the support plate 4.

[0046] Working principle: This solution can cut multiple wire harnesses simultaneously. By pulling the pull rod 16 upward with the connecting rod 19, the two conveying rollers 15 are separated, and the ends of multiple wire harnesses are sequentially placed between the two arc-shaped annular grooves 20. The upper and lower distributed arc-shaped annular grooves 20 clamp and limit the wire harnesses. Before cutting the wire harnesses at a fixed distance, the end face of the wire harness must be kept flush with the right end face of the second cutter 13 to ensure that the size of the first fixed-distance cut of the wire harness is consistent. The slider 7, carrying the first clamping plate 21 and the second clamping plate 22, moves towards the cutting frame 9 through the existing cylinder push rod or motor transmission assembly. When the L-shaped ends of the first clamping plate 21 and the second clamping plate 22 are at the upper and lower ends of the clamping space, the first clamping plate 21 and the second clamping plate 22 are driven to move towards each other by the upper and lower clamping structure in the prior art to clamp the ends of multiple wire harnesses. After clamping, the first clamping plate 21 and the second clamping plate 22 clamping the ends of the wire harnesses are moved to the right by the cylinder push rod or the motor transmission assembly until they stop at a predetermined distance. At this time, the first cutter 11 is moved downward by the cylinder push rod 10. The fixed-distance cutting of multiple wire harnesses can be completed by the action of the first cutter 11 and the second cutter 13.

[0047] In this design, as the slider 7 moves to the right, the crank 26 carries the lever 27 through the inside of the arc groove 25, causing the rotating sleeve 24 to deflect the support plate 4 on the surface of the optical axis 23 from an inclined state to a horizontal state. Through the mutual attraction of the two magnetic blocks, the support plate 4 can be kept in a horizontal state. That is, as the slider 7 moves with the clamped wire harness, multiple support plates 4 will sequentially change from an inclined state to a horizontal state. The horizontal support plates 4 support the bottom of the wire harness, thereby preventing the wire harness from becoming a downward-sweeping arc due to gravity after it is stretched. This ensures that the length error range of each wire harness cut at a fixed distance is small and the pass rate is higher.

[0048] In this solution, when the support plate 4 changes from an inclined state to a horizontal state, the arc surface of the arc-shaped guide block 39 restricts the dome rod 38, which can push the dome rod 38 and pull the extension rod 36 and one of the racks 32. Through the meshing of the rack 32 with the second gear 35 and the first gear 31, the two protective plates 30 can unfold to converge multiple wire harnesses, avoiding the wire harnesses from being scattered on the support plate 4 due to too many wire harnesses being cut at the same time, thus affecting the overall cutting error of the wire harnesses.
