Description

Technical Field

[0001] The utility model relates to the technical field of cable stripping, in particular to a positioning device for cable stripping. Background Art

[0002] In the process of cable manufacturing, due to the characteristics of production process and production equipment, unqualified scrapped products, cable ends and short ends after delivery are inevitably produced, which need to be stripped to recover valuable materials such as copper and plastic. Traditional wire stripping methods include manual stripping with a cutting knife, but the labor intensity is high, the efficiency is low, and it is easy to cause safety accidents such as cutting knife injuries. Traditional incineration will pollute the environment and waste the recyclable plastic insulation layer.

[0003] The prior art, for example, is a cable positioning device for a cable stripping machine recorded in patent publication number CN220382641U. The device cooperates with an adjustment seat with a cutter and a lifting frame with a rotating seat. During actual use, the device is synchronously adjusted by a cylinder. On the one hand, the cylinder is used to drive the adjustment seat up and down to adjust the distance between the end of the cutter and the V-shaped wheel, thereby meeting the purpose of accurately cutting the outer covering of cables of different diameters. On the other hand, the cylinder is used to drive the lifting frame up and down, and the limiting inclined plate is used to squeeze the execution wheel, driving the power arm and the rotating seat to rotate, so as to adjust the distance between the centering wheels and meet the clamping needs of cables of different diameters. Since the cutter and the centering wheel are adjusted synchronously, the cable to be processed can be quickly positioned, the cable is not easy to deviate, the structure is simple, it has market prospects, and is suitable for promotion and application.

[0004] In actual use, since the cable is often in a bent state, it needs to be positioned by two sets of centering wheels before the cutter can accurately cut the outer covering of the cable. The cutting accuracy of the first and last cable heads and the short heads after shipment is low.

[0005] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0023] like Figures 1 to 3 As shown, the utility model is a cable stripping positioning device comprising: a lifting frame 101, a lifting assembly 200, an adjustment assembly 300 and a positioning assembly 400;

[0024] The lifting assembly 200 includes a sleeve 202, which is installed in the through hole at the top of the lifting frame 101. A cylinder 201 is installed at the upper end of the sleeve 202. A lifting rod 203 is slidably arranged inside the cylinder 201 and the sleeve 202. An adjustment seat 103 is installed at the lower end of the lifting rod 203. A cutter 104 is rotatably arranged on the lower surface of the adjustment seat 103.

[0025] The adjustment assembly 300 includes a spur rack 301, which is vertically mounted on the top of the inner wall of the lifting frame 101, and is meshed with a gear 302. The gear 302 is mounted on a connecting shaft 305, and the connecting shaft 305 is mounted on the side of a main rotating rod 303. The main rotating rod 303 is rotatably arranged on a fixing seat 304, and the fixing seat 304 is symmetrically mounted on the side of the lifting rod 203. A connecting block 306 is mounted on the side of the main rotating rod 303 away from the connecting shaft 305, and a secondary rotating rod 307 is mounted on the side of the connecting block 306.

[0026] The positioning assembly 400 includes a moving wheel 401 and a fixed wheel 402. The moving wheel 401 is rotatably arranged at the lower end of the auxiliary rotating rod 307, and the fixed wheel 402 is rotatably arranged in a rectangular groove 403 at the bottom of the inner wall of the lifting frame 101. The central axes of the moving wheel 401 and the fixed wheel 402 are located in the same plane.

[0027] During actual use, the cylinder 201 is started to push the lifting rod 203 down. Due to the meshing of the gear 302 and the spur rack 301, the gear 302 drives the main rotating rod 303 to rotate. The main rotating rod 303 drives the auxiliary rotating rod 307 to rotate through the connecting block 306. The auxiliary rotating rod 307 drives the moving wheel 401 to fix the cable 102. At the same time, the lifting rod 203 drives the adjusting seat 103 to descend, so that the cutting depth of the blade on the cable 102 reaches the required depth.

[0028] Furthermore, the blade of the cutter 104 is aligned with the fixed wheel 402 , and when the fixed wheel 402 and the movable wheel 401 fix the cable 102 , the blade of the cutter 104 is aligned with the central axis of the cable 102 .

[0029] Furthermore, the length of the spur rack 301 is greater than the maximum distance between the gear 302 and the top of the interior of the lifting frame 101, so as to prevent the gear 302 from being separated from the spur rack 301 during the positioning process.

[0030] Furthermore, the length of the main rotating rod 303 is smaller than the distance between the fixing seat 304 and the adjusting seat 103 . When the diameter of the positioned cable 102 is small, the adjusting seat 103 will not hinder the moving wheel 401 from positioning the cable 102 .

[0031] Working principle: place the end of cable 102 on fixed wheel 402, start cylinder 201, push lifting rod 203 down, due to the meshing of gear 302 and spur rack 301, gear 302 drives main rotating rod 303 to rotate, main rotating rod 303 drives auxiliary rotating rod 307 to rotate through connecting block 306, so that auxiliary rotating rod 307 drives moving wheel 401 to fix cable 102, with the cooperation of fixed wheel 402, the blade of cutter 104 is aligned with the central axis of cable 102, and at the same time, lifting rod 203 drives adjusting seat 103 to descend, and adjusting seat 103 drives cutter 104 to descend to the position where the blade is sufficient to cut the outer sheath of cable 102, push cable 102, moving wheel 401 and rotating wheel to rotate, the end of cable 102 moves toward cutter 104, and the outer sheath of cable 102 is cut by cutter 104, so that the device can accurately cut the first and last cable heads and the short heads after delivery.
