Description

Technical Field

[0001] The utility model relates to the technical field of wire harness processing, in particular to a cutting and stripping device for wire harness processing. Background Art

[0002] The wiring harness is the overall service equipment for a certain load source group, such as relay lines, switching devices, control systems, etc. The wiring harness is the wiring component that connects various electrical devices in the circuit. It is composed of core wires, wire sheaths, etc. During the wiring harness processing, it is often necessary to cut and strip the core wires and wire sheaths of the wiring harness. Before using the wiring harness, the coils usually need to be opened and then cut to the required length of the wiring harness.

[0003] For example, the Chinese patent with the announcement number CN216819223U discloses a machine tool for processing wire harnesses, which is provided with a support column at the top of the bottom plate, a top plate at the top of the support column, a mounting frame at the top of the top plate, a cylinder at the top of the mounting frame, and a telescopic rod at the bottom of the cylinder. The threaded column is rotated by turning the rotating wheel to adjust the distance between the two cutting knives, and the wire harnesses of different diameters are stripped. The motor drives the rotation of the rotating shaft to make the cutting knife rotate quickly, and the cylinder controls the telescopic rod to push the installation box through the inside of the top plate, so that the cutting knife gradually contacts the wire harness, and the wire harness is cut. The wire harness stripping and cutting are carried out simultaneously, saving a lot of time. The traction wheel ensures that the wire harness is always in a tight state, which is convenient for processing the wire harness and improves the processing efficiency.

DETAILED DESCRIPTION

[0025] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0027] The wire harness loop is evenly paid out by the pay-off mechanism 5 without manual control. The limit assembly 2 can limit the wire harness during its movement to prevent unevenness of the subsequent cutting surface caused by the movement of the wire harness. The cutting and peeling assembly 3 can realize integrated cutting and peeling, and the cut wire harness can be transmitted through two electric transmission belts 38 rotating in opposite directions. The peeled wire sheaths can be collected uniformly by the wire sheath collection assembly 4 to prevent the accumulation of wire sheaths from affecting subsequent processing.

[0028] like Figure 2 and Figure 4 As shown, the limiting assembly 2 includes a vertical plate 21 and two limiting rollers 25. The lower end of the vertical plate 21 is fixedly installed at the front position of the middle part of the upper end of the base 1. A mounting plate is fixedly installed at the rear part of the upper end of the base 1. Connecting grooves 22 are provided at the tops of the opposite sides of the mounting plate and the vertical plate 21. Slide bars 23 are fixedly installed on the inner walls of the two connecting grooves 22. Slide bars 24 are slidably connected to the outer walls of the two slide bars 23. The front and rear ends of the top limiting roller 25 are rotatably connected to the opposite sides of the two slide bars 24. The front and rear ends of the bottom limiting roller 25 are rotatably connected to the bottoms of the opposite sides of the mounting plate and the vertical plate 21. An annular groove 27 is provided in the middle of the outer walls of the two limiting rollers 25.

[0029] The wire harness to be processed passes through two annular grooves 27, and the top limiting roller 25 slides on the corresponding slide rod 23 through two sliders 24 to adjust the distance between it and the bottom limiting roller 25, so that the two annular grooves 27 can pass wire harnesses of different sizes.

[0030] like Figure 4 As shown, the top of the outer wall of the two slide bars 23 is movably sleeved with a buffer spring 26 , the lower ends of the two buffer springs 26 are fixedly connected to the upper ends of the two slide blocks 24 , and the upper ends of the two buffer springs 26 are fixedly connected to the top of the inner wall of the two connecting grooves 22 .

[0031] The two buffer springs 26 can buffer the pressure exerted on the wire harness by the top limiting roller 25, so that the internal structure of the wire harness will not be damaged due to excessive pressure.

[0032] like Figure 2 and Figure 5 As shown, the cutting and peeling assembly 3 includes a top plate 31, the rear side of the top plate 31 is fixedly installed at the right position of the top front side of the mounting plate, an electric push rod 32 is fixedly installed at the upper end of the top plate 31, the output end of the electric push rod 32 passes through the top of the top plate 31 and is fixedly installed with a movable plate 33, an upper cutter 34 is fixedly installed at the middle part of the lower end of the movable plate 33, a bottom plate 35 is fixedly installed at the middle position of the right part of the front side of the mounting plate, a lower cutter 36 is fixedly installed at the upper left part of the bottom plate 35, and the right side of the upper cutter 34 overlaps with the left side of the lower cutter 36.

[0033] The output end of the electric push rod 32 drives the movable plate 33 to move, and the movable plate 33 drives the upper cutter 34 to approach the lower cutter 36 to achieve cutting and stripping work. The alternating arrangement of the upper cutter 34 and the lower cutter 36 facilitates cutting of wire harnesses of different sizes.

[0034] like Figure 2 , Figure 3 and Figure 5 As shown, a connecting plate 37 is fixedly installed at the front position of the upper right part of the base 1, and electric transmission belts 38 are fixedly installed at the upper and lower positions of the top of the connecting plate 37 and the mounting plate on the opposite sides. The rotation directions of the two electric transmission belts 38 are opposite. A limiting cylinder 39 is fixedly installed at the upper right part of the bottom plate 35, and the two electric transmission belts 38 are located on the right side of the limiting cylinder 39.

[0035] The two electric conveyor belts 38 rotating in opposite directions can drive the cut wire harness close to the upper cutter 34 and the lower cutter 36 to realize the stripping work of the wire harness end. Then the two electric conveyor belts 38 rotate in the opposite direction to transfer the processed wire harness, and the limit cylinder 39 has a limiting effect on the movement of the cut wire harness.

[0036] like Figure 5 and Figure 6As shown, the collecting wire skin assembly 4 includes two limit rods 42, and two movable grooves 41 are opened on the upper right part of the base 1. The front and rear ends of the two limit rods 42 are fixedly installed on the inner walls of the two movable grooves 41, and the rear parts of the outer walls of the two limit rods 42 are slidably connected with movable blocks 43. The upper ends of the two movable blocks 43 are fixedly installed with support plates 44, and the upper ends of the support plates 44 are fixedly installed with a collecting box 45. The collecting box 45 is located directly below the upper cutter 34 and the lower cutter 36.

[0037] The two moving blocks 43 move on the corresponding limiting rods 42 to drive the support plate 44 and the collecting box 45 to move out of the base 1, so that the operator can process the wire sheaths in the collecting box 45.

[0038] like Figure 6 As shown, an adjustable internal threaded sleeve 46 is rotatably connected to the bottom position of the rear right side of the mounting plate, and a threaded rod 47 is threadedly connected to the inner wall of the internal threaded sleeve 46. The front end of the threaded rod 47 passes through the rear of the mounting plate and is fixedly mounted to the rear bottom of the collection box 45.

[0039] By rotating the internal thread sleeve 46 , the threaded rod 47 is threadedly connected with the internal thread sleeve 46 to push the collection box 45 to move.

[0040] like Figure 6 As shown, the front parts of the outer walls of the two limit rods 42 are slidably connected with stop blocks 48, the rear sides of the two stop blocks 48 overlap the front sides of the two moving blocks 43, the front parts of the outer walls of the two limit rods 42 are movably sleeved with adjustment springs 49, the rear ends of the two adjustment springs 49 are fixedly connected to the front sides of the two stop blocks 48, and the front ends of the two adjustment springs 49 are fixedly connected to the front parts of the inner walls of the two moving grooves 41.

[0041] When the collection box 45 moves toward the front of the base 1 , the two moving blocks 43 stop moving after touching the two stop blocks 48 , and the two adjusting springs 49 play a buffering role, and the spring potential energy thereof can buffer the impact force received by the collection box 45 .

[0042] The working principle of the utility model is as follows: the operator places the wire harness loop to be processed on the wire release mechanism 5, which is driven by a motor and is an existing mechanism and will not be described in detail. The wire harness passes through two annular grooves 27, and two buffer springs 26 buffer the pressure exerted on the wire harness by the top limiting roller 25, and the two limiting rollers 25 can limit the wire harnesses of different sizes.

[0043] One end of the wire harness passes through the limit cylinder 39 and is located between the two electric conveyor belts 38. The two electric conveyor belts 38 drive the wire harness to move to the right to the specified position, and the electric push rod 32 is started. Its output end drives the upper cutter 34 to approach the lower cutter 36. The upper and lower cutters cut the wire harness, and the upper cutter 34 then moves up. The two electric conveyor belts 38 rotate in the opposite direction, which drives the wire harness to move to the left to the specified position after being cut. The electric push rod 32 drives the upper cutter 34 to move down again, and the upper and lower cutters peel the wire harness after being cut. The two electric conveyor belts 38 rotate again to drive the wire harness to move to the right, and the wire skin falls into the collection box 45, and the cut and stripped wire harness end is transmitted by the two electric conveyor belts 38.

[0044] After the collection box 45 has been collecting for a certain period of time, the internal threaded sleeve 46 is rotated to allow the threaded rod 47 to push the collection box. The collection box 45 moves by sliding the two moving blocks 43 on the two limit rods 42 until the two moving blocks 43 contact the two stop blocks 48 to stop the rotation of the internal threaded sleeve 46. The elastic potential energy of the two adjusting springs 49 can convert a certain impact force on the collection box 45, thereby increasing the service life of the collection box 45.

[0045] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
