Description

Technical Field

[0001] This utility model relates to the technical field of wire harness processing equipment, specifically a wire harness cutting device for automotive wire harness production. Background Technology

[0002] Wiring harness cutting devices are specialized equipment used to cut automotive wiring harnesses, such as engine wiring harnesses, instrument wiring harnesses, and door wiring harnesses, ensuring that the wiring harness length and cutting quality meet standards. They are widely used in industries such as automobile manufacturing, electronic equipment production, and home appliance manufacturing.

[0003] For example, the utility model patent disclosed in publication number CN222607871U discloses a wire harness cutting device for automotive wire harness production, including a cutting table; the top of the cutting table is fixedly connected to the bottom of a support frame, and electric push rods are provided on both sides of the top of the support frame. The top of the support frame is fixedly connected to the bottom of the electric push rods, and the bottom of the electric push rods is fixedly connected to the top of a first fixed block. A buffer mechanism is provided on the top of the cutting table; the buffer mechanism includes a second fixed block, which is located below the first fixed block. Through the design of the buffer mechanism, the function of buffering the cutting head is realized, which solves the problem that existing cutting devices do not have a buffer component for the cutting head. During long-term cutting processing, the downward pressure can easily damage the cutting head, making it unable to cut, thereby shortening the service life of the cutting head and increasing the later maintenance cost. This improves the protection of the cutting head.

[0004] Although the aforementioned cutting equipment can protect the cutting head, it does not lock the cutting head when cutting the wire harness, which may cause errors at the cutting points of multiple wire harnesses, thereby reducing the accuracy of the equipment in cutting the wire harness. Therefore, there is an urgent need for a wire harness cutting device for automotive wire harness production to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of this invention is to provide a wire harness cutting device for automotive wire harness production, so as to solve the problems mentioned in the background art.

[0007] An adjustable stroke cylinder is provided on the upper part of the feeding base and is fixedly connected to the support plate. A threaded sleeve is provided at the tail of the adjustable stroke cylinder for adjusting the stroke of the adjustable stroke cylinder.

[0008] A cutting device is fixedly installed at the output end of the adjustable stroke cylinder, and the cutting device is used to compress and cut the wire harness.

[0009] Preferably, the cutting device includes a positioning slide, a fixed bracket is provided at the center of the lower end face of the positioning slide, and spring guide shafts are provided at equal intervals at the bottom of the fixed bracket.

[0010] Preferably, the pressing device includes a positioning guide seat, five sets of alignment guide seats are symmetrically and equidistantly arranged on the lower end face of the positioning guide seat, and a spring guide seat is fixedly arranged on the lower end face of each set of alignment guide seats, and a pressing clamp is fixedly arranged on the lower end face of the spring guide seat.

[0011] Preferably, the upper end face of the alignment guide seat is pressed and connected to the fixed card seat. During alignment installation, multiple sets of alignment guide seats can perform secondary positioning of the fixed card seat after the fixed card seat is installed and locked.

[0012] Preferably, the pressing clamp has a V-shaped groove inside, and the bottom of the pressing clamp has a V-shaped groove, which can facilitate the subsequent locking and limiting of wire harnesses of different radii, thereby improving the adaptability of subsequent equipment to cutting and limiting different wire harnesses.

[0013] Preferably, the cutting tool is slidably connected to the inner end face of the feed base via the cutting guide groove. The cutting guide groove can provide sufficient guiding space for the cutting tool to cut the wire harness, thereby improving the stability of the subsequent cutting of the wire harness by the cutting tool.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model, by setting up a cutting device, allows multiple sets of pressing clamps to center and limit the wire harness before cutting it, ensuring that the wire harness is centered and directly aligned with the cutting tool. This improves the accuracy and stability of the subsequent cutting of the wire harness by the cutting tool. At the same time, multiple sets of spring guide shafts provide elastic buffering at the bottom of the cutting tool, preventing rigid contact between the cutting tool and the wire harness, which would reduce the service life of the cutting tool. This effectively improves the efficiency of the equipment in cutting the wire harness and also extends the service life of the cutting tool. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 This utility model provides an embodiment of a wire harness cutting device for automotive wire harness production, comprising a feeding base 4, at least five sets of feeding guide grooves 5 equidistantly provided on the upper end surface of the feeding base 4 for guiding materials, aluminum profile columns 8 provided at the four corners of the upper end surface of the feeding base 4, support plates 7 fixedly provided on the upper end surfaces of the four sets of aluminum profile columns 8, and a cutting guide groove 6 provided at the center of the upper end surface of the feeding base 4.

[0024] Adjustable stroke cylinder 2 is set on the upper part of the feeding base 4 and is fixedly connected to the support plate 7. A threaded sleeve 1 is provided at the tail of the adjustable stroke cylinder 2. The threaded sleeve 1 is used to adjust the stroke of the adjustable stroke cylinder 2.

[0025] Cutting device 3 is fixedly installed at the output end of adjustable stroke cylinder 2. Cutting device 3 is used to compress and cut the wire harness.

[0026] like Figure 3 and Figure 4 The cutting device 3 includes a positioning slide 31, a fixed bracket 35 is provided at the center of the lower end face of the positioning slide 31, and spring guide shafts 34 are provided at equal intervals at the bottom of the fixed bracket 35. A cutting tool 33 is provided at the lower end face of the spring guide shaft 34, and a pressing device 32 is provided at the lower end face of the positioning slide 31 near the outside.

[0027] like Figure 5 The pressing device 32 includes a positioning guide seat 321. Five sets of alignment guide seats 324 are symmetrically and equidistantly arranged on the lower end face of the positioning guide seat 321. A spring guide seat 322 is fixedly arranged on the lower end face of each set of alignment guide seats 324. A pressing clamp 323 is fixedly arranged on the lower end face of the spring guide seat 322.

[0028] The upper end face of the alignment guide seat 324 is pressed and connected to the fixed card seat 35. During alignment installation, multiple sets of alignment guide seats 324 can perform secondary positioning on the fixed card seat 35 after it is installed and locked.

[0029] The pressing clamp 323 has a V-shaped groove inside. The bottom of the pressing clamp 323 has a V-shaped groove, which can facilitate the subsequent locking and limiting of wire harnesses of different radii, thereby improving the adaptability of subsequent equipment to cutting and limiting different wire harnesses.

[0030] The cutting tool 33 is slidably connected to the inner end face of the feed base 4 through the cutting guide groove 6. The cutting guide groove 6 can provide sufficient guiding space for the cutting tool 33 to cut the wire harness, thereby improving the stability of the subsequent cutting of the wire harness by the cutting tool 33.

[0031] Working principle: During use, the operator can position the wire harness feeding module at the front of the feeding base 4 to facilitate the subsequent cutting of the wire harness inside the feeding guide 5. When cutting the wire harness, the operator can activate the adjustable stroke cylinder 2. At this time, the adjustable stroke cylinder 2 can drive the positioning slide 31 to move down. When the positioning slide 31 moves down, it can drive the cutting tool 33 and the pressing device 32 to move down synchronously. At this time, the pressing fixture 323 can first move the cutting tool 33 down to the inside of the feeding guide 5, and then center and lock the wire harness inside the feeding guide 5, so that the wire harness to be cut can be centered and limited. Then, the pressing fixture 323 gradually locks the wire harness further under the pressure of the spring guide 322. At this time, the cutting tool 33 can cut the locked wire harness. At the same time, the spring guide shaft 34 can buffer the cutting tool 33 to prevent the wire harness from causing rigid damage to the cutting tool 33.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
