Description

Technical Field

[0001] The utility model belongs to the field of wire stripping devices, and in particular relates to a wire harness stripping device. Background Art

[0002] When installing or repairing electrical equipment, it is necessary to peel off the insulation layer on the surface of the wire harness to expose the metal conductor inside the wire harness directly, so as to facilitate the next step of cutting, connecting or winding operations.

[0003] Currently, when installing or repairing electrical equipment, wire strippers, wire stripping knives, wire cutters, diagonal pliers, electrician's knives, etc. are usually used for the operation. This means that the quality of wire stripping is largely dependent on the operator's experience and skill level, which may lead to large differences in stripping quality between different operators. For example, the stripping depth of the wire harness is inconsistent, the insulation layer remains, or the degree of damage to the wire harness itself is damaged. These differences may affect the quality and reliability of the entire electrical equipment. Secondly, with the above-mentioned stripping method, long-term stripping can easily lead to operator fatigue, reducing work efficiency, and there is a risk of accidental injury from the stripping tool.

[0028] See also Figure 1As shown, a wire harness stripping device comprises a frame workbench 1, on the surface of which a clamping mechanism 2 for clamping the wire harness and a stripping mechanism 3 for stripping the insulation layer on the surface of the wire harness are provided;

[0029] See also Figure 2-3 As shown, in this embodiment, the wire stripping mechanism 3 includes a pair of first linear guide rails 31, and a movable plate 32 is provided on the slide of the pair of first linear guide rails 31. A first cylinder 33 is connected to the rear side wall of the movable plate 32. The movable plate 32 can move back and forth in the Y direction along the first linear guide rail 31 by the drive of the first cylinder 33. A fixed block 34 is provided on the upper end surface of the movable plate 32, and a lower wire stripping cutter 35 is provided on the fixed block 34. An upper wire stripping cutter 36 is provided directly above the lower wire stripping cutter 35. The upper wire stripping cutter 36 is provided on the piston rod of a lifting cylinder 38 through a connecting seat 37. The lifting cylinder 38 is fixed to the upper end surface of the movable plate 32 through a support seat 39. The upper wire stripping cutter 36 can move up and down in the Z direction by the drive of the lifting cylinder 38.

[0030] For further information, see Figure 2-3 As shown, two groups of wire shafts 41 are passed through the connecting seat 37 through linear bearings 40. The upper ends of the wire shafts 41 are fixedly connected to the support seat 39, and the lower ends of the wire shafts 41 are fixedly connected to the fixed block 34. In this embodiment, two groups of wire shafts 41 are provided, which are respectively arranged on both sides of the lifting cylinder 38. During operation, the upper wire stripping cutter 36 is guided by the wire shafts 41 to move up and down to avoid deviation of the upper wire stripping cutter 36.

[0031] For further information, see Figure 2 As shown, a guide groove 351 is provided on the lower wire stripping cutter 35; during operation, the insulation layer stripped from the wire harness is discharged through the guide groove 351, thereby preventing the stripped insulation layer from accumulating on the lower wire stripping cutter 35 and affecting subsequent wire harness operations.

[0032] For further information, see Figure 3 As shown, a first limit block 42 is provided on the lower end surface of the movable plate 32, and a first blocking block 11 adapted to the first limit block 42 is provided on the table surface of the frame workbench 1; during operation, the first limit block 42 and the first blocking block 11 cooperate to limit the maximum position of the movable plate 32 moving along the first linear guide rail 31 in the positive direction of the Y axis to ensure that the wire stripping position is constant.

[0033] For further information, see Figure 1As shown, a receiving port 12 connected to the inner cavity of the frame workbench 1 is provided on the table top of the frame workbench 1, and the receiving port 12 is used to collect the wire harness insulation layer discharged from the guide groove 351 into the inner cavity of the frame workbench 1; and in this embodiment, a circle of baffles 13 is provided around the upper end of the receiving port 12, and the baffles 13 are trumpet-shaped; wherein, in order to avoid the wire harness insulation layer collected in the inner cavity of the frame workbench 1 from being directly scattered and accumulated in the inner cavity of the frame workbench 1, thereby increasing the subsequent cleaning workload, a positioning groove 14 for positioning the collection bucket is provided on the bottom surface of the inner cavity of the frame workbench 1. During operation, the collection bucket is installed in the inner cavity of the frame workbench 1 through the positioning groove 14. At this time, the opening of the collection bucket faces the receiving port 12, and the opening of the collection bucket is larger than the receiving port 12, and the wire harness insulation layer discharged into the inner cavity of the frame workbench 1 is collected centrally through the collection bucket.

[0034] See also Figure 4-5 As shown, in this embodiment, the clamping mechanism 2 includes a pair of second linear guide rails 21, and a fixed seat 22 is provided on the slide of the pair of second linear guide rails 21. A second cylinder 23 is connected to the right side wall of the fixed seat 22, and the fixed seat 22 can move back and forth in the X direction along the second linear guide rail 21 by the drive of the second cylinder 23; a finger cylinder 24 is provided on the left side wall of the fixed seat 22, and the clamping claw of the finger cylinder 24 is provided with a splint 25. During operation, the wiring harness is tightened and fixed by the splint 25; and in this embodiment, in order to achieve accurate control of the tightening position of the splint 25, a second limit block 26 is provided on the lower end surface of the fixed seat 22, and a second blocking block 15 adapted to the second limit block 26 is provided on the table surface of the frame workbench 1.

[0035] See also Figure 1 As shown, in this embodiment, the device also includes a support block 4, which supports the wiring harness to facilitate the clamping plate 25 to tighten and fix the wiring harness. The support block 4 is fixed on the table top of the frame workbench 1, and a V-shaped groove 401 is provided on the upper end surface of the support block 4. The V-shaped groove 401 can effectively prevent the wiring harness from swinging on the support block 4.

[0036] The working principle of this utility model is as follows:

[0037] See also Figure 6 As shown in the figure (label A in the figure represents this device; label B in the figure represents the collection bucket; label C in the figure represents the wire harness), before operation, the collection box is placed in the inner cavity of the frame workbench 1 through the positioning groove 14.

[0038] During operation, the equipment is started. At this time, the first cylinder 33 pushes the movable plate 32 to move along the first linear guide rail 31 in the positive direction of the Y axis until the first limit block 42 conflicts with the first stop block 11; then the operator inserts the front end of the wire harness to be stripped into the wire stripping mechanism 3 until the front end of the wire harness presses against the rear side wall of the lower wire stripping cutter 35, and then places the wire harness in the V-groove 401 of the support block 4 and holds it; then the second cylinder 23 pushes the fixed seat 22 to move along the second linear guide rail 21 in the negative direction of the X axis until the second limit block 26 conflicts with the second stop block 15, and the finger cylinder 24 drives the clamping plate 25 to clamp the wire harness; then the lifting cylinder 38 pushes the upper wire stripping cutter 36 to move in the negative direction of the Z axis to remove the insulation layer of the wire harness After cutting, the first cylinder 33 pushes the movable plate 32 to move along the first linear guide rail 31 in the negative direction of the Y axis to strip the insulation layer from the metal conductor of the wire harness. At this time, the stripped insulation layer slides along the guide groove 351 and falls into the collection box through the receiving port 12; after stripping is completed, the lifting cylinder 38 pushes the upper wire stripping cutter 36 to move in the positive direction of the Z axis to reset. At the same time, the finger cylinder 24 drives the clamping plate 25 to release the tightening of the wire harness; then, the second cylinder 23 pushes the fixed seat 22 to move in the positive direction of the X axis along the second linear guide rail 21 to reset; then the operator pulls out the wire harness, and the first cylinder 33 pushes the movable plate 32 to move in the positive direction of the Y axis along the first linear guide rail 31 to reset to the stripping position, preparing for the next round of wire stripping.

Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
