[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0024] Refer to Figure 1 And Figure 2, an embodiment provided by the present utility model: a fixed-length cutting device for power cables, including a workbench 1. One side of the surface at one end of the workbench 1 is fixedly connected with a fixed frame 2. Four support frames 9 are fixedly connected to the surface at the end of the workbench 1 far from the fixed frame 2. A second motor 11 is fixedly connected to one end surface of the fixed frame 2. The output end of the second motor 11 penetrates the fixed frame 2 and extends into the interior of the fixed frame 2 to be fixedly connected with a screw rod 12. One outer wall of the screw rod 12 is threadedly connected with a first sliding plate 13. One end surface of the first sliding plate 13 is slidably connected to the inner outer wall of the fixed frame 2. One end surface of the first sliding plate 13 is fixedly connected with a moving plate 14. The bottom surface of the moving plate 14 is slidably connected to the upper surface of the fixed frame 2. The middle of the end surface of the moving plate 14 far from the first sliding plate 13 is fixedly connected with a first connecting plate 7. A chute 10 is opened in the interior of the first connecting plate 7. The middle and lower part of one end surface of the first connecting plate 7 is fixedly connected with a second fixing plate 18. The height of the second fixing plate 18 should be kept at the same height as the lower conveying roller 4 on the first fixing plate 3. One end surface of the moving plate 14 close to the first connecting plate 7 is fixedly connected with a second cylinder 15. The output end of the second cylinder 15 is fixedly connected with a lifting plate 16. One end surface of the lifting plate 16 is slidably connected to the inner outer wall of the first connecting plate 7 close to the chute 10. One side end surface of the lifting plate 16 is fixedly connected with a second connecting plate 17. The second connecting plate 17 is arranged corresponding to the second fixing plate 18. The second connecting plate 17 is slidably connected to the end surface of the first connecting plate 7 far from the second cylinder 15. One end surface of the second connecting plate 17 is fixedly connected with a laser rangefinder 19. The middle of the end surface of the first connecting plate 7 far from the second cylinder 15 is fixedly connected with two limiting plates 20. The two limiting plates 20 are respectively arranged on the left and right sides of the chute 10. Two first fixing plates 3 are fixedly connected to one end surface of the workbench 1. A moving mechanism is provided on one end surface of one first fixing plate 3.
[0025] Specifically, the retraction of the piston rod of the second cylinder 15 can keep the distance between the second fixing plate 18 and the second connecting plate 17 at the length of one cable diameter. The limiting plate 20 can prevent the excessive descent of the second connecting plate 17. The initial position of the first sliding plate 13 should make the second fixing plate 18 and the second connecting plate 17 on the front side of the third fixing plate 30, so that the second fixing plate 18 and the second connecting plate 17 can fix the cable conveyed by the two conveying rollers 4, and use the screw rod 12 and the first sliding plate 13 to move the cable head to a certain position; this setting can move the cable to different positions according to requirements to change the length change of the cable head and the cutter 33.
[0026] Refer to Figure 1 、 Figure 3 and Figure 4, the moving mechanism includes a third motor 23, a bidirectional threaded rod 25, and a second slide plate 26. The top surface of a first fixing plate 3 is fixedly connected to the third motor 23. The output end of the third motor 23 penetrates through the first fixing plate 3 and extends into the interior of the first fixing plate 3 to be fixedly connected to the bidirectional threaded rod 25. One side outer wall of the bidirectional threaded rod 25 is threadedly connected to two symmetrically arranged second slide plates 26. The internal thread directions of the two second slide plates 26 are opposite and are respectively adapted to the corresponding regions of the bidirectional threaded rod 25. An installation groove 28 is formed inside a first fixing plate 3. The two second slide plates 26 are slidably connected to the inner outer wall of the first fixing plate 3 close to the installation groove 28. One side end surface of the second slide plate 26 is fixedly connected to a clamping plate 24. One end surface of the first fixing plate 3 away from the second sprocket 22 is fixedly connected to two guide rails 27. The two guide rails 27 are respectively arranged on the left and right sides of the installation groove 28. The clamping plate 24 is slidably connected to the guide rails 27.
[0027] Specifically, since the entire assembly is arranged close to the conveying roller 4, the bidirectional threaded rod 25 is rotated by the third motor 23, and the two clamping plates 24 can be moved relatively or away from each other through the two second slide plates 26, thereby fixing the cable. The guide rails 27 can prevent the deviation of the clamping plates 24. When the first slide plate 13 is about to reach the designated location, the third motor 23 can be started to fix the cable. On the one hand, it can prevent the conveying roller 4 from continuing to convey the cable. On the other hand, the second connecting plate 17 and the second fixing plate 18 can cooperate to straighten the cable so as to cut off the cable.
[0028] Refer to Figure 1 and Figure 3 , one end surface of the workbench 1 is fixedly connected to a first motor 5. The output end of the first motor 5 is fixedly connected to a second sprocket 22. One side of the second sprocket 22 is connected to a first sprocket 6 through a chain 21. The end surface of the second sprocket 22 away from the first motor 5 is fixedly connected to a conveying roller 4. The end surface of the first sprocket 6 is fixedly connected to another conveying roller 4. Both conveying rollers 4 are rotatably connected to the first fixing plate 3.
[0029] Specifically, the cable can be conveyed out through the two conveying rollers 4, which is convenient for the second connecting plate 17 and the second fixing plate 18 to fix the cable.
[0030] Refer to Figure 1 and Figure 5 , one end surface of the workbench 1 is fixedly connected to a first cylinder 8. The output end of the first cylinder 8 is fixedly connected to a mounting plate 32. One end surface of the mounting plate 32 away from the first cylinder 8 is fixedly connected to a cutter 33. One end surface of the workbench 1 is fixedly connected to four round rods 29. The top surface of the round rods 29 is fixedly connected to a third fixing plate 30. One end surface of the third fixing plate 30 away from the round rods 29 is fixedly connected to a baffle 31. The mounting plate 32 is slidably connected to the round rods 29.
[0031] Specifically, the height of the baffle 31 should be consistent with the height at which the second connecting plate 17 is finally fixed, so as to facilitate the laser rangefinder 19 to measure the length of the cut cable and facilitate timely adjustment of the length, and the cutter 33 can cut the cable.
[0032] Working principle: The cable is conveyed to the surface of the second fixing plate 18 by two conveying rollers 4. At the initial position of the first slide plate 13, the second cylinder 15 is started, and the second connecting plate 17 and the second fixing plate 18 can fix the cable head. Then, the first slide plate 13 is conveyed a certain distance by the second motor 11 and the screw rod 12, so that the cable can be further pulled out; when the first slide plate 13 is about to reach the designated location, the third motor 23 is started, and the two second slide plates 26 can move relatively through the bidirectional threaded rod 25, so that the two clamping plates 24 can fix the cable and straighten the cable to avoid cable slack.
[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
