Description

Technical Field

[0001] The present invention relates to the field of automobile wiring harnesses, and in particular to a cutting device for automobile wiring harness production and processing and a use method thereof. Background Art

[0002] The automotive wiring harness is the main network of the automotive circuit. Without the wiring harness, there would be no automotive circuit. The wiring harness refers to the components that are bundled with the wiring harness to form a circuit connection after the contact terminal (connector) made of copper material is crimped with the wires and cables, and then the insulator is plastic-pressed or metal shell is added.

[0003] Therefore, when producing and processing automotive wiring harnesses, the raw material cables must often be cut according to the requirements, and the production and packaging of cables are often carried out in bundles. Therefore, before cutting the cables, in order to facilitate subsequent storage and use, the cables will be straightened first, so that the cables can always remain in a straight state after cutting, and it is also more convenient to strip the ends and crimp the terminals. In the prior art, the use of cables will select cables of various models according to different parts of different models. The thickness specifications of such cables are also different, which has different requirements for straightening machines. Moreover, the existing straightening is often single cable straightening, and then fixed length cutting is performed after straightening. This does not meet the rapid processing requirements of existing assembly line plants, and because different cables require different straightening machines, various models of machines will still be selected for straightening, thereby increasing the actual processing cost.

DETAILED DESCRIPTION

[0047] Below, the invention is further described in conjunction with the accompanying drawings and specific embodiments:

[0048] Example 1: Please refer to Figure 1-3 A cutting device for automobile wiring harness production and processing according to an embodiment of the present invention comprises a table 1, wherein legs 2 are fixedly installed at the four corners of the bottom of the table 1, an outer cover 3 is fixedly installed at one end of the top of the table 1, a straightening mechanism 4 is arranged inside the outer cover 3, the straightening mechanism 4 is fixedly installed on the table 1, a wire assembly 5 is also installed on the top of the table 1, the wire assembly 5 is arranged on one side of the straightening mechanism 4, and a cutting assembly 6 is also installed on the side of the table 1 away from the straightening mechanism 4, a wiring tray 7 is arranged along its length direction at the center of the top of the table 1, the bottom of the wiring tray 7 is fixedly installed on the table 1 through a support block 8, a vertical plate 11 is fixedly installed at one end of the top of the table 1 away from the outer cover 3, a fixed seat 12 arranged opposite to the vertical plate 11 is fixedly installed on the top of the outer cover 3, a cross bar 9 is fixedly installed between the fixed seat 12 and the vertical plate 11, and a wire pulling mechanism 10 is slidably installed on the cross bar 9.

[0049] The end of the raw cable to be cut is passed through the straightening mechanism 4, and then through the conductor assembly 5 and the cutting assembly 6, so that the wire pulling mechanism 10 is close to the cutting assembly 6, and the wire pulling mechanism 10 is used to clamp the end of the straightened cable, and then the wire pulling mechanism 10 is adjusted to move on the cross bar 9. When the cable is stretched to a fixed length by the wire pulling mechanism 10, the cutting assembly 6 is adjusted to cut the stretched cable, and then the wire pulling mechanism 10 is adjusted to loosen the end of the cut cable, and the cable will automatically fall onto the wiring tray 7, and then the cut cable can be collected. In this process, the cable can be straightened before cutting it, and then ensure that the cable after cutting can always remain in a straight state, which is not only convenient for subsequent unified collection and bundling storage, but also can avoid the cables from being entangled with each other. Moreover, the cable that remains in a straight state is also convenient for subsequent end stripping and terminal crimping operations, thereby improving the efficiency of wire harness processing.

[0050] See also Figure 4-9 In order to enable the straightening mechanism 4 to perform straightening operations on multiple cables, in this embodiment, the straightening mechanism 4 includes a pillar 13 fixedly mounted on the top of the table 1, and a horizontal strip 14 is fixedly mounted on the top end of the pillar 13. The horizontal strip 14 is arranged along the width direction of the table 1. There are two horizontal strips 14, and a bearing seat 15 is fixedly mounted on the top of the horizontal strip 14. A straightening component 16 is rotatably mounted between the two oppositely arranged bearing seats 15. Each cable is passed through a different straightening component 16 separately, and the straightening component 16 can be used to straighten the cable, and different straightening components 16 can straighten the cables without interfering with each other, and multiple straightening components 16 can straighten multiple cables at the same time.

[0051] In order to enable the straightening assembly 16 to effectively straighten the cable, in this embodiment, the straightening assembly 16 includes a hollow column 17, and the two ends of the hollow column 17 are respectively connected with a first hollow shaft 18 and a second hollow shaft 19, and the first hollow shaft 18 and the second hollow shaft 19 are rotatably connected to the horizontal strip 14 through a bearing seat 15. The ends of the first hollow shaft 18 and the second hollow shaft 19 away from the hollow column 17 are fixedly installed with a wire head 20, and the second hollow shaft 19 is also fixedly installed with a first driven pulley 21. The first driven pulley 21 is driven to rotate by an external force, and the first driven pulley 21 can drive the hollow column 17 to rotate synchronously through the second hollow shaft 19. When the cable passes through the second hollow shaft 19, the hollow column 17 and the first hollow shaft 18, the cable inside the hollow column 17 can be straightened, and then with the pulling of the wire pulling mechanism 10, the hollow column 17 can be used to straighten the cable.

[0052] In order to make the rotation of the hollow column 17 effective for straightening the cable, in this embodiment, the hollow column 17 is provided with an assembly hole 22, which is perpendicular to the length direction of the hollow column 17, and a straightening block 24 is fixedly installed inside the assembly hole 22, and a straightening hole 25 is provided on the straightening block 24 and is arranged through the body thereof, and locking bolts 26 are also installed at both ends of the assembly hole 22, and when the straightening block 24 is installed inside the assembly hole 22, the straightening hole 25 is arranged coaxially with the hollow column 17. The straightening block 24 can be selected according to actual conditions and can be replaced according to the size of the cable, so that the straightening hole 25 can adapt to cables of different thicknesses, thereby ensuring effective straightening of the cable. For the convenience of observation, an observation hole 23 is also provided on the outer wall of the hollow column 17, and the observation hole 23 is arranged between two adjacent assembly holes 22, and the length direction of the observation hole 23 is perpendicular to the length direction of the assembly hole 22.

[0053] In order to reduce friction when the cable passes through the second hollow shaft 19 and passes through the first hollow shaft 18, in this embodiment, the wire head 20 is internally rotatably installed with a wire sleeve 27, and the wire sleeve 27 is coaxially arranged with the hollow column 17. In order to enable all hollow columns 17 to synchronously straighten the cables, the first driven pulleys 21 on the two adjacent second hollow shafts 19 are connected by a first transmission belt 28. With this arrangement, when one of the second hollow shafts 19 is rotated under force, all the hollow columns 17 can be indirectly driven to rotate synchronously.

[0054] See also Figure 10-14In order to enable the second hollow shaft 19 to achieve synchronous rotation adjustment, in this embodiment, a first motor 29 is fixedly installed on the bottom of the table 1 close to the outer cover 3, and a first driving pulley 30 is fixedly installed on the end of the output shaft of the first motor 29. The first driving pulley 30 is connected to the first driven pulley 21 at the outermost side through a second transmission belt 31, and a second strip hole 65 for the second transmission belt 31 is also provided on the table 1.

[0055] In order to enable the wire assembly 5 to effectively guide the cables straightened by the straightening assembly 16, in the present embodiment, a guide rail 32 arranged along the width direction of the table 1 is fixedly installed on the top of the table 1, and the wire assembly 5 includes a movable seat 33, and a guide block 34 is fixedly installed on the bottom of the movable seat 33, and the guide block 34 is slidably arranged on the guide rail 32, and a base 36 is fixedly installed on the top of the movable seat 33, and a bottom frame 38 is rotatably installed on the top center of the base 36 through a first bearing 37, and a cam 39 is rotatably installed on the bottom frame 38, and a vertical rod 40 is fixedly installed through the four corners of the base 36, and a top seat 41 is fixedly installed on the top end of the vertical rod 40, and a top frame 43 is rotatably installed on the bottom center of the top seat 41 through a second bearing 42, and a concave wheel 44 is rotatably installed on the bottom of the top frame 43, and the concave wheel 44 and the cam 39 are adapted to each other. The cables passing through the first hollow shaft 18 can pass between the concave wheel 44 and the cam 39, so that they can be guided by the concave wheel 44 and the cam 39. The position of the base 36 can be adjusted by the movable seat 33, and then the position of the straightened end of the cable can be adjusted, so that all the cables can be gathered together, so that when they are cut and fall onto the wiring tray 7, they can be automatically gathered together for easy collection.

[0056] In order to enable the wire assembly 5 to automatically gather and spread, in the present embodiment, a connecting bolt 35 is fixedly installed on one side of the movable seat 33, a first strip hole 64 is also opened on the table plate 1, and an adjusting mechanism (not shown) is fixedly installed on the bottom of the table plate 1, one end of the adjusting mechanism passes through the first strip hole 64 and is connected to the connecting bolt 35, and the position of the movable seat 33 is adjusted and limited by the adjusting mechanism, and the position of the wire assembly 5 can be appropriately adjusted according to the cables of different specifications in actual situations, so that it can better guide the straightened wire harness.

[0057] In order to enable the cutting assembly 6 to effectively cut the wire harness, in this embodiment, the cutting assembly 6 includes a support rod 45 fixedly mounted on the top of the table 1, a support plate 46 fixedly mounted on the top end of the support rod 45, the support plate 46 is arranged on the side of the wire assembly 5 away from the straightening mechanism 4, and a fixing frame 47 is fixedly mounted on the top end of the support plate 46, a hydraulic cylinder 48 is fixedly mounted on the top of the fixing frame 47, a lifting plate 49 is arranged inside the fixing frame 47, the output shaft of the hydraulic cylinder 48 passes through the top of the fixing frame 47 and is connected to the top of the lifting plate 49, and a cutter 50 is fixedly mounted on the bottom of the lifting plate 49 away from the wire assembly 5. When the straightened cable is stretched by the wire pulling mechanism 10, the lifting plate 49 can be driven to move by adjusting the hydraulic cylinder 48, and then the cutter 50 can be driven to move toward the support plate 46. When the cutter 50 cuts the cable, the cable can fall onto the wiring tray 7.

[0058] In order to prevent the cut cable from being retracted into the straightening mechanism 4 due to the pulling force, in this embodiment, a vertical rod 51 is penetrated by the lifting plate 49 near both ends, and a limiting nut 52 is fixedly installed on the top of the vertical rod 51, and a pressure plate 53 is fixedly installed on the bottom end of the vertical rod 51, and the pressure plate 53 is arranged close to the wire assembly 5. A spring 54 is also sleeved on the outside of the vertical rod 51, and the spring 54 is arranged between the pressure plate 53 and the lifting plate 49, and when the pressure plate 53 and the cutter 50 are not in contact with the support plate 46, the distance between the pressure plate 53 and the support plate 46 is smaller than the distance between the cutter 50 and the support plate 46.
