Description

Technical Field

[0001] This utility model relates to the technical field of cutting and positioning devices, specifically a cutting and positioning device for the production of cable protection pipes. Background Technology

[0002] Cable protection pipes are metal protective pipes with a certain mechanical strength, laid on the outer layer of cables to prevent damage. They are mainly installed at intersections where communication cables and power lines cross to prevent short circuits caused by power line breaks, which could lead to energization of communication cables and steel wire ropes. This protects cables, switches, circuit boards, and even the entire device from burning out. They also provide some isolation against magnetic field interference from power lines. Traditionally, cable protection pipes are cut manually, which has low positioning efficiency. To improve this, a cutting and positioning device for cable protection pipe production is proposed.

[0003] For example, the cutting and positioning device for producing cable protection pipes disclosed in the authorization announcement number CN222521479U includes a chassis, a fixed base fixedly connected to the upper end of the chassis, a first slide rail provided at the upper end of the fixed base, the first slide rail being symmetrically distributed at the front and rear ends of the fixed base; a mounting base, the lower end of the mounting base being fixedly connected to the upper end of the fixed base, a first slide block slidably connected to the upper end of the mounting base via a second slide rail, the first slide blocks being symmetrically distributed at the left and right ends of the mounting base, a folding plate fixedly connected to the front end of the first slide block by bolts and nuts, a sliding groove provided at the front end of the mounting base, a fixed plate fixedly connected to the upper end of the mounting base by bolts, and a screw threadedly connected to the fixed plate;

[0004] Although it achieves a clamping and holding mechanism composed of mounting base, slide rail, slide block, folding plate, clamping plate, fixing plate and screw, which can prevent the protective tube from dislodging and is conducive to stable cutting; the positioning mechanism composed of fixing base, slide rail, slide block, lifting rail, slide block and cutting machine can determine the cutting direction and is conducive to precise cutting;

[0005] However, the existing cutting and positioning device does not solve the problems that make it difficult to conveniently clamp and fix the protective tube at the linkage center and move, transport, and position the protective tube to determine the cutting length, nor does it facilitate circumferential rotation cutting of the protective tube, thus affecting the convenience of positioning and cutting. Utility Model Content

[0006] The purpose of this utility model is to provide a cutting and positioning device for the production of cable protection pipes, so as to solve the problems mentioned in the background art, which are not convenient for the linkage center to clamp and fix the protection pipe and move, transport and position the protection pipe to position the cutting length, and are not conducive to the circumferential rotation cutting of the protection pipe, thus affecting the convenience of positioning and cutting.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cutting and positioning device for producing cable protection pipes, comprising a worktable and a bearing ring. The bearing ring is disposed above the worktable, and auxiliary rings are disposed on both sides of the bearing ring. Three sets of integrated frames with equal spacing are installed between the bearing ring and the auxiliary rings. Limiting blocks are installed on the top of the worktable on one side of the auxiliary rings, and the auxiliary rings are slidably connected to the limiting blocks. A toothed ring is installed on the outer wall of the bearing ring. A servo motor is installed on the top of the worktable on one side of the toothed ring. A gear is installed at the output end of the servo motor, and the gear meshes with the toothed ring. A bearing seat is installed on the outer wall of the worktable, and an auxiliary roller is disposed on the inner wall of the worktable, and the auxiliary roller is movably connected to the worktable.

[0008] Preferably, each of the integrated frames has a lead screw movably installed inside, and a drive motor is provided on the auxiliary ring sidewall at one end of each lead screw, with the output end of the drive motor connected to the lead screw.

[0009] Preferably, the surface of the lead screw is fitted with a threaded sleeve, and the threaded sleeve is threadedly connected to the lead screw.

[0010] Preferably, an adjusting arm is movably mounted on the side wall of the threaded sleeve, and a linkage arm is movably mounted on the end of the adjusting arm away from the threaded sleeve.

[0011] Preferably, each of the linkage arms is provided with a linkage shaft at the end near the integrated frame, and the linkage arm is movably connected to the integrated frame through the linkage shaft, and an electric wheel is installed at the end of the linkage arm away from the linkage shaft.

[0012] Preferably, a cylinder is installed on the side wall of the bearing seat, and a push arm is installed at the output end of the cylinder.

[0013] Preferably, a cutting machine is installed at the end of the push arm away from the cylinder, and the cutting machine is slidably connected to the worktable.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the cutting and positioning device not only realizes the convenient linkage center clamping and fixing of the protective tube and the moving, conveying and positioning of the protective tube to the cutting length, which facilitates the circumferential rotation cutting of the protective tube, but also improves the convenience of positioning and cutting.

[0015] (1) Insert the protective tube into the bearing ring and auxiliary ring. The drive motor drives the lead screw to rotate, which in turn drives the threaded sleeve to move. The threaded sleeve then drives the adjusting arm to rotate, which in turn drives the linkage arm to rotate around the linkage shaft. The integrated frame provides support for the linkage arm, which in turn drives the electric wheel to rotate and contact the outer wall of the protective tube. With the synchronous cooperation of the three sets of electric wheels, the protective tube is clamped and fixed in the center. The electric wheel drives the protective tube to move and contact the inside of the worktable. At the same time, the auxiliary roller is inserted into the inside of the protective tube to provide movable support. The distance from the cutting machine to the inner wall of the worktable is the length to be cut, thus completing the positioning of the protective tube. The cylinder drives the push arm to move, which in turn drives the cutting machine to move, so that... The saw blade of the cutting machine contacts the outer wall of the protective tube, and the cutting machine cuts the protective tube. Because the diameter of the protective tube is large, the cutting machine cannot cut the protective tube completely. A servo motor drives the gear to rotate, and the gear drives the bearing ring, auxiliary ring, integrated frame and protective tube to rotate in a circle to cut the protective tube. After the cutting is completed, the cutting machine resets and at the same time controls the electric wheel to move the protective tube away from the auxiliary roller and remove the cut protective tube. Then the above operation is repeated to position and cut the protective tube sequentially. It realizes convenient linkage center clamping and fixing of the protective tube, facilitates the movement, transportation and positioning of the protective tube for cutting length, facilitates the circumferential rotation cutting of the protective tube, and improves the convenience of positioning and cutting.

Limiting blocks 18 are installed on the top of the workbench 1 on one side of the auxiliary rings 20, and the auxiliary rings 20 are slidably connected to the limiting blocks 18. A toothed ring 8 is installed on the outer wall of the bearing ring 9. A servo motor 6 is installed on the top of the workbench 1 on one side of the toothed ring 8. The servo motor 6 plays the role of power driving. A gear 7 is installed at the output end of the servo motor 6, and the gear 7 meshes with the toothed ring 8. A bearing seat 2 is installed on the outer wall of the workbench 1, and an auxiliary roller 10 is arranged on the inner wall of the workbench 1, and the auxiliary roller 10 is movably connected to the workbench 1.

[0024] Inside the integrated frame 19, lead screws 17 are movably installed. A drive motor 11 is provided on the side wall of the auxiliary ring 20 at one end of the lead screw 17. The drive motor 11 plays the role of power driving, and the output end of the drive motor 11 is connected to the lead screw 17.

[0025] The surface of the lead screw 17 is fitted with a threaded sleeve 16, and the threaded sleeve 16 is threadedly connected to the lead screw 17. An adjusting arm 15 is movably installed on the side wall of the threaded sleeve 16, and a linkage arm 13 is movably installed at the end of the adjusting arm 15 away from the threaded sleeve 16.

[0026] Each of the linkage arms 13 is provided with a linkage shaft 12 at the end near the integrated frame 19, and the linkage arms 13 are movably connected to the integrated frame 19 through the linkage shaft 12. Each of the linkage arms 13 is provided with an electric wheel 14 at the end away from the linkage shaft 12.

[0027] A cylinder 3 is installed on the side wall of the support 2. The cylinder 3 serves as a power drive. A push arm 4 is installed at the output end of the cylinder 3. A cutting machine 5 is installed at the end of the push arm 4 away from the cylinder 3, and the cutting machine 5 is slidably connected to the worktable 1.

[0028] Insert the protective tube into the bearing ring 9 and auxiliary ring 20. Turn on the drive motor 11, which drives the lead screw 17 to rotate. With the lead screw 17 and threaded sleeve 16 connected by threads, the lead screw 17 drives the threaded sleeve 16 to move. The threaded sleeve 16 drives the adjusting arm 15 to rotate. The adjusting arm 15 drives the linkage arm 13 to rotate around the linkage shaft 12. The integrated frame 19 provides support for the linkage arm 13. The linkage arm 13 drives the electric wheel 14 to rotate, so that the electric wheel 14 contacts the outer wall of the protective tube. With the synchronous cooperation of the three sets of electric wheels 14, the protective tube is clamped and fixed in the center. Then, turn on the electric wheel 14, which drives the protective tube to move and contact the inside of the worktable 1. At the same time, the auxiliary roller 10 is inserted into the inside of the protective tube to provide movable support. The distance from the cutting machine 5 to the inner wall of the worktable 1 is the length to be cut, thus completing the positioning of the protective tube. Then, turn on the cylinder 3, which drives the push arm 4 to move. The cutting machine 5 is moved so that its saw blade contacts the outer wall of the protective tube. The cutting machine 5 is then turned on to cut the protective tube. Because the diameter of the protective tube is large, the cutting machine 5 cannot cut it completely. At this time, the servo motor 6 is turned on, which drives the gear 7 to rotate. Under the mutual meshing of the gear 7 and the gear ring 8, and the sliding cooperation of the auxiliary ring 20 and the limit block 18, the gear 7 drives the bearing ring 9, the auxiliary ring 20, the integrated frame 19 and the protective tube to rotate in a circle to cut the protective tube. After the cutting is completed, the cutting machine 5 is reset. At the same time, the electric wheel 14 is operated to move the protective tube away from the auxiliary roller 10 and remove the cut protective tube. Then, the above operation is repeated to position and cut the protective tube in sequence. This realizes convenient linkage center clamping and fixing of the protective tube, facilitates the movement, transportation and positioning of the protective tube for cutting length, facilitates the circumferential rotation cutting of the protective tube, and improves the convenience of positioning and cutting.

[0029] Working principle: The protective tube is inserted into the bearing ring 9 and auxiliary ring 20. The drive motor 11 drives the lead screw 17 to rotate, which in turn drives the threaded sleeve 16 to move. The threaded sleeve 16 drives the adjusting arm 15 to rotate, which in turn drives the linkage arm 13 to rotate around the linkage shaft 12. The integrated frame 19 provides support for the linkage arm 13, which in turn drives the electric wheel 14 to rotate, bringing the electric wheel 14 into contact with the outer wall of the protective tube. With the synchronous cooperation of the three sets of electric wheels 14, the protective tube is clamped and fixed in the center. The electric wheel 14 drives the protective tube to move and contact the inside of the worktable 1. At the same time, the auxiliary roller 10 is inserted into the inside of the protective tube to provide movable support. The distance from the cutting machine 5 to the inner wall of the worktable 1 is the length to be cut, thus completing the positioning of the protective tube. The cylinder 3 drives the push arm 4 to move, which in turn drives the cutting machine 5 to move, so that the saw blade of the cutting machine 5 contacts the outer wall of the protective tube. The cutting machine 5 cuts the protective tube. Because the diameter of the protective tube is large, the cutting machine 5 cannot cut the protective tube completely. The servo motor 6 drives the gear 7 to rotate. With the sliding cooperation between the auxiliary ring 20 and the limit block 18, the gear 7 drives the bearing ring 9, the auxiliary ring 20, the integrated frame 19 and the protective tube to rotate in a circle through the gear ring 8 to cut the protective tube. After the cutting is completed, the cutting machine 5 resets and at the same time, the electric wheel 14 is operated to move the protective tube away from the auxiliary roller 10 and remove the cut protective tube. Then, the above operation is repeated to position and cut the protective tube in sequence. The above is the complete usage of the cutting and positioning device for cable protection tube production.
