Description

Technical Field

[0001] This utility model relates to the field of cutting devices, and in particular to a cutting device for automotive wiring harness processing. Background Technology

[0002] Cutting equipment for automotive wiring harness processing is a core piece of equipment in the automotive wiring harness production process. It is mainly used for precise cutting and insulation stripping of wiring harnesses composed of multi-strand wires and insulation layers. It is a key piece of equipment to ensure the dimensional accuracy and electrical performance of the wiring harness. The prior art discloses a cutting device for automotive wiring harness production and processing with patent number CN222902493U, which includes: a machine base, a mounting frame, and a cutting mechanism for cutting the wiring harness. When the cutter cuts the wiring harness, the cutter is subjected to force. The force of the buffer spring is used to buffer the cutter, thereby reducing the pressure on the cutter and ensuring the service life of the cutter.

[0003] The prior art discloses a cutting device for automotive wire harness production and processing, patent number CN216297832U, which includes a worktable. The wire harness in this cutting device is engaged with a limiting groove, which is slidably connected to a placement groove via a second lead screw and a third servo motor. The limiting groove is also telescopically connected to the placement groove via a second electric push rod. Furthermore, a moving block is slidably connected to the worktable horizontally and vertically via a fourth servo motor, a first servo motor, and a first lead screw. This design facilitates wire harness straightening and adjustment of the cutting position.

[0004] With the development of multi-material automotive wiring harnesses, the debris generated during the cutting process of existing devices is prone to sticking to the blade. If the blade surface is not cleaned in time after the impurities stick, the subsequent cutting accuracy will decrease. This application adapts to different production scenarios through a linkage time-sharing cleaning structure and replaceable component design. Utility Model Content

[0005] 1. Technical problems to be solved The core of this utility model lies in solving the problem of wire debris easily sticking to the blade during wire harness cutting in the prior art through a linkage time-sharing cleaning structure. At the same time, the replaceable component design can be adapted to different production scenarios.

[0006] Technical solution

[0007] To solve the above problems, the present invention adopts the following technical solution.

[0008] A cutting device for automotive wiring harness processing includes a cutting assembly. The cutting assembly includes multiple horizontally arranged strip-shaped bases. A support top is fixedly connected to the upper end of each strip-shaped base. A hydraulic push rod is fixedly connected to the middle of the upper end of the support top. A pressing block is installed at the output end of the hydraulic push rod. A cutting blade is fixedly connected to the middle of the lower end of the pressing block. A cutting groove is formed in the middle of the strip-shaped base, located directly below the cutting blade. A linkage wiping assembly is fixedly connected to the inner end of the cutting groove. The linkage wiping assembly includes multiple springs. Sponge strips are fixedly connected to the outer sides of two springs located in a horizontal position. A pair of strip-shaped through slots are formed at the upper end of the strip-shaped base. The two strip-shaped through slots are located on the front and rear sides of the cutting groove, respectively. A pair of rectangular slots are formed on the inner side of the strip-shaped through slots near the cutting groove. A wedge-shaped transverse moving block is slidably connected to the inner end of the rectangular slot. The two sponge strips are fixedly connected to the corresponding wedge-shaped transverse moving block. Two sets of wedge-shaped vertical moving blocks are symmetrically fixedly connected to the front and rear sides of the lower end of the pressing block.

[0009] Furthermore, the wedge-shaped vertical moving block one extends into the corresponding strip-shaped through groove and engages with the wedge-shaped horizontal moving block two in a wedge shape, and a placement groove is provided at the upper end of the strip-shaped base.

[0010] Furthermore, the two sets of springs are fixedly connected to the corresponding sponge strips, and the cutting blade penetrates vertically between the two sponge strips.

[0011] Furthermore, a tear-off replacement assembly is fixedly connected to one end of the sponge strip near the cutting blade, the tear-off replacement assembly including a positive-side Velcro.

[0012] Furthermore, the outer end of the positive side hook and loop fastener is attached to the negative side hook and loop fastener, and the end of the negative side hook and loop fastener away from the positive side hook and loop fastener is fixedly connected to a cleaning blade cloth.

[0013] Optionally and preferably, an air jet cleaning assembly is fixedly connected to the inner end of the cutting groove. The air jet cleaning assembly includes strip-shaped horizontal plates that are fixedly connected to the left and right inner walls of the cutting groove, respectively.

[0014] Furthermore, multiple air jet blocks are fixedly connected to one end of the two strip-shaped horizontal plates that are close to each other. A pump is connected to the strip-shaped horizontal plates through pipes. A chip removal groove is fixedly connected to the lower end of the cutting groove. A suction pipe is fixedly connected to the front end of the chip removal groove. An industrial-grade vacuum cleaner is connected to the suction pipe. Beneficial effects

[0015] Compared with existing technologies, the advantages of this utility model are: (1) This solution achieves the timing coordination of the cutting blade entering first and the wedge moving later by designing the height difference between the cutting blade and the wedge moving block. Combined with the initial separation state of the sponge strip, it avoids the sharp blade from contacting the wiping parts from the source, effectively protecting the blade precision and the integrity of the wiping strip, and reducing the component wear rate.

[0016] (2) At the same time, the Velcro structure of the tear-off replacement component makes it easy to replace the wiping blade cloth, the maintenance time is short, the maintenance cost is low, and it is suitable for the production needs of small and micro enterprises with low cost and low frequency of maintenance.

[0017] (3) The jet cleaning component forms a directional airflow field through the jet blocks on the strip plate, and with the pump, it provides high pressure to remove dust outside the blade, avoiding the adhesion of small impurities and affecting the cutting accuracy of the next cut, thus meeting the stringent cleanliness requirements of mature enterprises in mass production.

[0020] The technical solution will now be clearly and completely described with reference to the accompanying drawings in the embodiments of this utility model.

[0021] Example 1:

[0022] Please see Figures 1-5The system includes a cutting assembly 1, which comprises multiple horizontally arranged strip-shaped bases 100. A support top 101 is fixedly connected to the upper end of each strip-shaped base 100. A hydraulic push rod 102 (model HOB100x300) is fixedly connected to the middle of the upper end of the support top 101. A lower pressure block 103 is installed at the output end of the hydraulic push rod 102. A cutting blade 104 is fixedly connected to the middle of the lower end of the lower pressure block 103. A cutting groove 105 is formed in the middle of the strip-shaped bases 100, directly below the cutting blade 104. A linkage wiping assembly 2 is fixedly connected to the inner end of the cutting groove 105. The linkage wiping assembly 2 includes multiple springs 200. Two horizontally positioned springs 200 are fixedly connected to the outer sides of sponge strips 20. 1. A pair of strip-shaped through grooves 202 are provided at the upper end of the strip-shaped base 100. The two strip-shaped through grooves 202 are located on the front and rear sides of the cutting groove 105 respectively. A pair of rectangular grooves 204 are provided on the inner side of the end of the strip-shaped through groove 202 near the cutting groove 105. A wedge-shaped transverse block 205 is slidably connected to the inner end of the rectangular groove 204. Two sponge strips 201 are fixedly connected to the corresponding wedge-shaped transverse block 205 respectively. Two sets of wedge-shaped vertical blocks 203 are symmetrically fixedly connected to the front and rear sides of the lower end of the pressure block 103. The height of the cutting blade 104 is shorter than that of the wedge-shaped vertical blocks 203. Two sets of springs 200 are symmetrically fixedly connected to the front and rear inner walls of the cutting groove 105. The wire harness is in a taut state during cutting to facilitate smooth cutting.

[0023] The wedge-shaped vertical moving block 1 203 extends into the corresponding strip-shaped through groove 202 and wedges together with the wedge-shaped horizontal moving block 205. The upper end of the strip-shaped base 100 is provided with a wire placement groove 106. The two sets of springs 200 are fixedly connected to the corresponding sponge strips 201 respectively. The cutting blade 104 vertically penetrates the position between the two sponge strips 201. The end of the sponge strip 201 near the cutting blade 104 is fixedly connected to the tear-off replacement component 3. The tear-off replacement component 3 includes a positive side hook and loop fastener 300. The outer end of the positive side hook and loop fastener 300 is attached to the negative side hook and loop fastener 301. The end of the negative side hook and loop fastener 301 away from the positive side hook and loop fastener 301 is fixedly connected to the wiping blade cloth 302.

[0024] Please see Figures 1-5During cutting, the wire harness is positioned in the wire placement groove 106 of the strip base 100. The hydraulic push rod 102 on the support top seat 101 drives the lower pressure block 103 to move downward, causing the cutting blade 104 to move towards the cutting groove 105 to complete the cutting operation. The cutting blade 104 enters the gap between the two sponge strips 201 before the wedge-shaped vertical moving block 203. Because the blade height is shorter than the wedge-shaped vertical moving block 203, and the sponge strips are kept separated under the natural extension of the spring 200 in the initial state, the gap is slightly larger than the blade thickness to avoid contact with the wiping component during the cutting stage. The cutting blade 104 continues to move downward to the cutting groove 105 to complete the wire harness cutting. In the final stage of cutting, the wedge-shaped vertical moving block 203 enters the strip through groove 202 after the blade, moving along with the lower pressure block. The step moves down and forms a wedge-shaped engagement with the second wedge-shaped transverse block 205, triggering a lateral thrust that drives the second wedge-shaped transverse block 205 to move horizontally along the rectangular groove 204. Finally, it pulls the sponge strip 201 to compress the spring 200 and close. When the lower pressure block 103 is raised, the closed sponge strip 201 tightly adheres to the surface of the cutting blade 104 under the action of the spring rebound force. The residual insulation layer debris is wiped away by tearing and replacing the blade wiper cloth 302 fixed by the back Velcro 301 in the replacement component 3. When the blade wiper cloth is worn, it can be directly peeled off from the front Velcro 300 and replaced with the back Velcro 301. The maintenance cost is low and the operation is simple. It avoids damage to the wiping parts when the sharp blade is cutting. It is suitable for scenarios that need to protect the precision of the blade and is suitable for the initial production line of small and micro enterprises.

[0025] Example 2:

[0026] Please see Figures 6-7 An air jet cleaning assembly 4 is fixedly connected to the inner end of the cutting groove 105. The air jet cleaning assembly 4 includes two strip-shaped horizontal plates 400 fixedly connected to the left and right inner walls of the cutting groove 105 respectively. Multiple air jet blocks 401 are fixedly connected to the ends of the two strip-shaped horizontal plates 400 that are close to each other. A pump 402 is connected to the strip-shaped horizontal plates 400 through pipes. The model can be an air compressor V-0.17 / 8. A chip removal groove is fixedly connected to the lower end of the cutting groove 105. A suction pipe is fixedly connected to the front end of the chip removal groove. An industrial-grade vacuum cleaner is connected to the suction pipe.

[0027] This embodiment retains the cutting component 1 and the air jet block 401 on the strip horizontal plate 400 on the left and right inner walls of the cutting groove 105. The air jet block 401 is delivered by an external pump 402 to blow away the fine dust, such as copper wire fragments and glass fiber insulation powder, on the blade surface and the cutting groove 105. The blown-off fine dust is collected by the chip drop trough and sucked by an external industrial-grade vacuum cleaner through the suction pipe. It is suitable for scenarios with extremely high cleanliness requirements and is compatible with the mass production lines of mature enterprises.

[0028] The above are merely preferred embodiments of this utility model; they encompass all the protection scope of this utility model. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be covered within the protection scope of this utility model.
