Description

Technical Field

[0001] The present invention relates to the field of shearing technology, and in particular to a fixed-length shearing device for wiring harness cables of new energy vehicles. Background Art

[0002] The wiring harness cables of new energy vehicles are the network body of the automobile circuit. Without the wiring harness cables, there will be no automobile circuit. In the processing of the wiring harness cables, the wire harness cables wound into rolls need to be cut into small sections to facilitate the subsequent production and processing of the wire harness cables. Cutting equipment is required for the cutting of the wire harness cables.

[0003] In the process of using the existing automobile wiring harness cable cutting equipment, in order to ensure the cutting stability, the shear knife used for cutting is usually firmly fixed on the cutting equipment. However, with the increase of the use time, the shear knife will inevitably be damaged to the extent that it needs to be replaced. However, since the shear knife is fixed too firmly, it will increase the difficulty of replacing the shear knife, and it will take a lot of time and energy to replace the shear knife. Therefore, the present invention improves a shearing device that can both firmly position the shear knife and facilitate the replacement of the shear knife. Summary of the invention

[0011] In at least some embodiments, a cylindrical limiting slide post is installed inside the mounting slot; the diameter of the limiting slide post matches the diameter of the mounting hole; and a disk-shaped force-bearing slide disk is fixedly installed on the outer end of the limiting slide post.

[0017] 2. The present invention can indirectly convert the descending force into an inward movement force through the cooperation of the structure and provide it to the clamping slider when the shear blade descends to pre-cut the wire harness cable, so that the clamping slider can clamp and position the wire harness cable from the left and right sides by moving inward, so that the two groups of clamping sliders clamp the two ends of the wire harness cable to be cut, preventing the wire harness cable from being pulled during the cutting process, and avoiding the deviation of the pre-measured length of the wire harness cable due to pulling during cutting, resulting in inaccurate cutting length.

[0034] Please refer to Figures 1 to 8 : Example

[0035] The present invention proposes a fixed-length cutting device for wiring harness cables of new energy vehicles, comprising: a support base plate 1, a fixed-length screw rod 2 is rotatably installed at the center position inside the support base plate 1; a hand wheel is fixedly installed at the front end of the fixed-length screw rod 2; guide slide plates 3 are fixedly installed at the left and right ends of the inner side of the support base plate 1; a fixed-length ruler 4 is also fixedly installed inside the support base plate 1; a cutting base 5 is also slidably installed on the guide slide plate 3; a connecting piece 6 is fixedly installed at the bottom of the cutting base 5; the connecting piece 6 is also connected to the fixed-length screw rod 2 through a thread; a support plate body 7 is fixedly installed on the left and right sides of the top of the cutting base 5; the support plate body 7 A supporting cross plate 8 is fixedly installed on the inner side; a circular threading hole 9 is opened in the center of the supporting cross plate 8; clamping grooves 10 are opened on the left and right sides of the supporting cross plate 8; the clamping grooves 10 are connected with the threading hole 9; a shearing seat 11 is fixedly installed in the center of the top of the shearing base 5; the shearing seat 11 is located between the two groups of supporting plate bodies 7; an arc-shaped wire supporting groove 12 is opened in the center of the top of the shearing seat 11; a mounting top plate 13 is fixedly installed on the top of the supporting plate body 7; push blocks 14 are fixedly installed at the four corners of the bottom of the mounting top plate 13; the bottom end of the push block 14 is an inclined structure.

[0036] During cutting, it is necessary to manually use a hand wheel to rotate the fixed-length screw rod 2 so that the fixed-length screw rod 2 can move along the guide slide 3 with the cutting base 5 through rotation, so that the staff can adjust the position of the cutting base 5 through the scale on the fixed-length ruler 4, so as to facilitate cutting the unharnessed cables into small segments of different lengths by changing the position of the cutting base 5.

[0037] Embodiment 2, on the basis of embodiment 1, a shear cylinder 15 is fixedly installed at the center position of the top of the mounting top plate 13; a clamping slider 16 is slidably installed inside the clamping slide 10; the inner side of the clamping slider 16 is an arc-shaped structure; a transmission slide 17 is fixedly installed on the outer side of the clamping slider 16; a rectangular embedded baffle 18 is fixedly installed on the outer side of the transmission slide 17; a spring A19 is embedded between the left and right adjacent embedded baffles 18; a transmission slide 20 is opened on the outer side of the transmission slide 17; the transmission slide 20 consists of a vertical groove and an inclined groove, and the inclined groove is located above the vertical groove; a shearing slide 21 is slidably installed on the inner side of the support plate body 7; the shearing slide 21 is located above the shearing seat 11; transmission slide posts 22 are fixedly installed on the front and rear sides of the shearing slide 21; the transmission slide post 22 is a cylindrical structure; the outer end of the transmission slide post 22 is also slidably installed inside the transmission slide 20; mounting components 23 are fixedly installed on the left and right sides of the bottom of the shearing slide 21.

[0038] By pulling one end of the cable out of the cable roller, passing the end through the threading hole 9 to the position of the rear support seat plate 1, and then starting the shear cylinder 15, the shear cylinder 15 will descend with the shear slide plate 21 and the shear blade 24. During the descent, the push block 14 will slide out from the inside of the force slide groove 30. At this time, the force slide plate 28 will quickly recover under the action of the spring B29, and insert the limit slide column 27 into the installation socket 25, positioning the shear blade 24 in the two installation components 23, thereby ensuring the stability of the shear blade 24 in the subsequent shearing process. When the shearing slide plate 21 and the shearing blade 24 rise to complete the shearing, after rising to a certain position, the pushing block 14 will be inserted into the force-bearing slide groove 30, and push the inclined surface of the force-bearing slide groove 30, so that the force-bearing slide groove 30 is forced to move outward with the force-bearing slide plate 28 and the limiting slide column 27, so that the limiting slide column 27 is withdrawn from the inside of the mounting socket 25, and the clamping fixation of the shearing blade 24 is cancelled, so that the shearing blade 24 is in the mounting assembly 23 by utilizing the structural friction between the shearing blade 24 and the mounting assembly 23. At this time, the staff only needs to use a little force to pull out the shearing blade 24 to take it out and replace it.

[0039] Embodiment 3, on the basis of embodiment 2, a shear blade 24 is installed in the internal sliding insertion of the installation component 23; circular installation sockets 25 are provided on the left and right sides of the shear blade 24; installation slide grooves 26 are provided on the front and rear sides of the installation component 23; a cylindrical limiting slide column 27 is installed in the internal sliding insertion of the installation slide groove 26; the diameter of the limiting slide column 27 matches the diameter of the installation socket 25; a force-bearing slide plate 28 with a disc-shaped structure is fixedly installed on the outer end of the limiting slide column 27; one end of a spring B29 is embedded in the inner side of the force-bearing slide plate 28; the other end of the spring B29 is embedded in the inner wall of the installation slide groove 26; a force-bearing slide groove is provided on the top of the force-bearing slide plate 28 30; the top of the force-bearing slide 30 is an inclined structure; the top of the shearing slide 21 is connected to the output end of the shearing cylinder 15; the inclined surface of the bottom end of the pushing block 14 contacts the inclined surface of the force-bearing slide 30; when the shearing slide 21 moves downward, the pushing block 14 will slide out from the inside of the force-bearing slide 30; after the pushing block 14 slides out from the inside of the force-bearing slide 30, the force sliding plate 28 and the limiting slide column 27 will move inward and be inserted into the inside of the mounting socket 25 under the action of the spring B29; when the shearing slide 21 moves downward, the limiting slide column 27 will also use its own sliding to move the transmission slide 17 and the clamping slide 16 inward along the clamping slide 10 under the action of the transmission slide 20.

[0040] When the shearing slide 21 moves downward, the shearing slide 21 will also utilize the transmission slide column 22 to be slidably installed under the action of the transmission slide groove 20. Through the characteristics of the inclined groove part of the transmission slide groove 20, the downward force is converted into an inward movement force and provided to the transmission slide 17, so that the transmission slide 17 moves relatively inward along the clamping slide groove 10 with the clamping slide 16, so that the clamping slide 16 fixes the cable to be cut, avoiding the cable being entangled due to the force during cutting, and preventing the cut cable from being of substandard length.

[0041] Working principle:

[0042] When shearing, first adjust the position of the shear base 5 as needed, and use the hand wheel to rotate the fixed-length screw rod 2, so that the fixed-length screw rod 2 can move along the guide slide 3 with the shear base 5 by rotation, so that the staff can adjust the position of the shear base 5 through the scale on the fixed-length ruler 4, so that the wire harness cables can be cut into small segments of different lengths by changing the position of the shear base 5. After the adjustment is completed, one end of the cable is pulled out from the cable roller, and the end is pulled through the threading hole 9 to the position of the rear support seat plate 1, and then the shear cylinder 15 is started to make the shear cylinder 15 descend with the shear slide 21 and the shear blade 24. During the descent, the push block 14 will slide out from the inside of the force slide groove 30. At this time, the force slide disc 28 will quickly recover under the action of the spring B29, and insert the limiting slide column 27 into the installation socket 25 to position the shear blade 24 in the two installation components 23, thereby ensuring the stability of the shear blade 24 in the subsequent shearing process, and when the shear slide 21 moves downward, the shear slide 21 will also use the transmission slide column 22 to slide and install Under the action of the transmission slide 20, through the characteristics of the inclined groove part of the transmission slide 20, the downward force is converted into an inward force and provided to the transmission slide 17, so that the transmission slide 17 moves relatively inward along the clamping slide 10 with the clamping slide 16, so that the clamping slide 16 fixes the cable to be cut, and then after the shear blade 24 descends and contacts the cable, the shear blade 24 will use the downward force to cooperate with the shear seat 11 to cut the cable, and then restore through the shear cylinder 15, so that the shear cylinder 15 brings the shear slide 21 and the shear blade 24 When the shear blade 24 is lifted up to a certain position, the pushing block 14 is inserted into the force-bearing slide groove 30 and pushes the inclined surface of the force-bearing slide groove 30, so that the force-bearing slide groove 30 is forced to move outward with the force-bearing slide plate 28 and the limiting slide column 27, so that the limiting slide column 27 is withdrawn from the inside of the mounting socket 25, and the clamping fixation of the shear blade 24 is cancelled, so that the shear blade 24 is in the mounting component 23 by utilizing the structural friction between the shear blade 24 and the mounting component 23. At this time, the staff only needs to use a little force to pull out the shear blade 24 to take it out and replace it.
