Description

Technical Field

[0001] This utility model relates to a wire stripping device for wire harness processing, belonging to the technical field of wire harness processing equipment. Background Technology

[0002] The wire harness consists of multiple single-strand wires. Plugs or slots are installed at both ends of the wire harness. During the wire harness production process, the single-strand wires in the wire harness need to be cut into sections first. Then, the outer sheaths of both ends of the wires are stripped to expose the battery core. This is mainly done manually with wire stripping pliers. It is more difficult to strip wires with larger diameters. If too much force is applied, the battery core will be damaged.

[0062] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0063] Please see Figure 1 and Figure 2 A wire stripping device for wire harness processing includes a table 1, a pull-back assembly 2 disposed on the table, and a cutting drive assembly 3;

[0064] The moving blade assembly 4 is mounted on the cutting drive assembly 3;

[0065] The fixed blade assembly 5 is directly below the moving blade assembly 4;

[0066] The cutting drive assembly 3 drives the moving blade assembly 4 to move toward the fixed blade assembly 5;

[0067] The pull-back assembly 2 is located behind the fixed blade assembly 5 and moves along the Y-axis direction to pull off the peeled outer skin.

[0068] It also includes a switch 6 for operation.

[0069] Please see Figure 3 and Figure 4 This is one embodiment of the pull-back assembly 2, which includes a direct-push cylinder 21 connected to the table 1, with the piston rod of the direct-push cylinder 21 facing the moving knife assembly 5.

[0070] A slide rail 22 with the same direction of movement is provided in front of the direct-push cylinder 21. A slider 23 is slidably arranged on the slide rail 22, and a support seat 24 is installed on the top of the slider 23.

[0071] A clamping cylinder 25 is mounted on the support base 24, and the two clamping arms 251 of the clamping cylinder 25 are close to the fixed tool assembly 5.

[0072] The two clamping arms 251 of the clamping cylinder 25 move relative to each other along the Z-axis.

[0073] The wire is inserted into the fixed blade assembly 5 from the Y-axis direction and extends a certain distance. At this time, the two clamping arms 251 of the clamping cylinder 25 open, and the extended end of the wire is located between the two clamping arms 251. After the moving blade assembly 4 descends to the contact position to achieve cutting, the two clamping arms 251 perform a closing motion to pull off the peeled skin.

[0074] To improve the friction between the clamping arms 251 and the peeling skin, the clamping areas of the two clamping arms 251 are provided with rough plates 252 with rough textured clamping surfaces.

[0075] Please see Figure 5 and Figure 6 This is one embodiment of the cutting drive assembly 3. The cutting drive assembly 3 includes a back frame 31 vertically connected to the table 1. A lead screw 34 with its axis vertically arranged is provided on one side of the front of the back frame 31. The upper and lower ends of the lead screw 34 are respectively supported by bearing seats 32. A movable nut 33 is screwed to the lead screw 32.

[0076] The moving blade assembly 4 is connected to the movable nut 33;

[0077] The lower end of the lead screw 32 is connected to the main shaft of the motor 35.

[0078] Using the above scheme, the motor 35 rotates, driving the lead screw 34 to rotate, realizing the up and down movement of the moving nut 33, which in turn drives the moving knife assembly 4 to move together.

[0079] Please see Figures 7 to 8The moving blade assembly 4 also includes an upper mounting plate 41, which is connected to the movable nut 33;

[0080] The top of the movable tool holder 42 is connected to the mounting plate 41, and the movable tool seat 43 is installed at the lower end of the movable tool holder 42;

[0081] The moving blade 44 is mounted on the moving blade holder 43. The blade body of the moving blade 44 extends along the X-axis direction, and the moving blade is provided with a plurality of upper cutting edges 44a evenly distributed along the X-axis direction.

[0082] The fixed blade assembly 5 also includes a lower fixing plate 51, which is connected to the lower end of the back frame 31.

[0083] The fixed tool holder 52 is installed on the top of the lower fixed plate 51, and the fixed tool seat 53 is installed on the top of the fixed tool holder 52;

[0084] The fixed blade 54 is mounted on the fixed blade holder 53. The blade body of the fixed blade 54 extends along the X-axis direction. The fixed blade is provided with a plurality of lower cutting edges 54a evenly distributed along the X-axis direction.

[0085] The upper cutting edge 44a and the lower cutting edge 54a correspond one-to-one.

[0086] Using the above scheme, with an equal number of upper cutting edges 44a and lower cutting edges 54a, multiple wires can be stripped at once, thus improving efficiency.

[0087] Please see Figures 9 to 10 As a further embodiment, an upper pressure strip 45 is also installed on the moving blade holder 43, and the upper pressure strip 45 is located behind the moving blade 44;

[0088] A pressure bar 55 is also installed on the fixed blade holder 53, and the pressure bar 55 is located behind the fixed blade 54.

[0089] The lower pressure strip 55 and the upper pressure strip 45 are positioned opposite each other and are used to press down on the wire from behind, ensuring that the wire is in a relatively horizontal position when stripping its insulation. Figure 10 As can be seen, the lower pressure strip 55 and the upper pressure strip 45 protrude from the bottom of the grooves of the lower cutting edge 54a and the upper cutting edge 44a, respectively. In order to peel smoothly, the lower pressure strip 55 and the upper pressure strip 45 need to have a certain deformation capacity, so they are made of silicone plates.

[0090] Please see Figures 12 to 13 The wire will droop in front of the fixed blade 54 and the moving blade 44 due to gravity, which will affect the shape of the stripping position. A support platform 7 is also provided in front to support the wire. The support platform 7 includes a base 71, which is fixed on the table 1.

[0091] A support plate 72 is installed on the top of the base 71. The top of the support plate 72 is provided with a through groove 72a, and the pressure block 73 is movably placed in the groove 72a.

[0092] To improve the holding effect, the pressure block 73 is made of iron.

[0093] The height of the pressure block 73 is higher than the depth of the groove 72a, making it easier to pick up.

[0094] Support platform 7 is optional, because the lower pressure bar 55 and upper pressure bar 45 are already installed, which can ensure that the shape of the peeling position meets the usage requirements.

[0095] When in use, first pass the wire through the groove 72a in sequence and through the lower cutting edge 54a. The two clamping arms 251 of the clamping cylinder 25 are attached to the back of the lower pressure bar 55, and a small part of the front end of the wire is located between the two clamping arms 251.

[0096] Next, the pressure block 73 is placed into the groove 72a, and the switch 6 is pressed. Under the action of the motor 35, the moving knife holder 42 is driven to descend. The upper blade 44a and the lower blade 54a move to cut off the outer skin. The two clamping arms 251 of the clamping cylinder 25 at the rear end pull the separated outer skin backward. Then the two clamping arms 251 open, and the separated outer skin falls down under the action of gravity.

[0097] To facilitate material feeding, table 1 has a notch at the material feeding position. Figure 1 As can be seen in the image, a waste basket (not shown in the image) can also be placed below the gap to collect waste.

[0098] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
