Description

Technical Field

[0001] The utility model relates to the technical field of cable cabling equipment, in particular to a lever device for a cage stranding machine. Background Art

[0002] The ￠1250 cage stranding machine is specially used for the cabling of plastic insulated and rubber power cables. It is mainly used for the cabling of the maximum single wire diameter: ￠25mm, the maximum outer diameter of the cabling is ￠65, and it can cable round wires and fan-shaped wires. The stranding cage of this cage stranding machine consists of a hollow shaft, a capstan, a wire reel rack, a wire splitter, etc. The wire reel rack inside the stranding cage is mechanically controlled, and the tension can be adjusted manually; the wire reel rack is shaftless, and the wire reel is tightened by shaking the lead screw of the manual clamping device, and the manual clamping device is also protected by a mechanical locking mechanism.

[0003] When the ￠1250 cage stranding machine is started normally, the cabled conductive insulated wire core drives the pay-off drum to rotate, and the pay-off drum drives the wheel to rotate through the lever device. By manually adjusting the tightness of the tension belt on the driving wheel, the tension of the conductive insulated wire core released from each drum frame can be stable and adjustable.

[0004] In order to meet the needs of customers for producing long-length conductive insulated wire cores on the ￠1250 cage stranding machine, it is necessary to install a non-standard, widened corrugated pay-off drum in the existing stranding cage. If the existing lever device is still used, the non-standard, widened corrugated pay-off drum cannot be installed due to the influence of the distance between the wire reel racks. If the existing lever device is not used, the non-standard, widened corrugated pay-off drum can be installed on the wire reel rack, but without a reasonably designed lever device, the tension of the conductive insulated wire core released from each wire reel rack is not easy to adjust.

[0005] How to design a lever device that meets production needs for the widened corrugated pay-off drum installed in the cage of the cage stranding machine has always been a difficult problem that has troubled technical personnel in cable companies. Utility Model Content

[0006] The purpose of the utility model is to provide a lever device for a cage stranding machine to solve the problems raised in the above-mentioned background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A lever device for a cage stranding machine comprises a mounting cover plate, on which a screw hole II is eccentrically arranged, a plurality of through holes are evenly arranged, and the through holes are provided with hexagon socket cylindrical head screws for fastening to the outer surface of a driving wheel; a lead screw, which is threadedly connected to the screw hole II, and a smooth rod is fixedly arranged at the insertion end of the lead screw, and the insertion end of the smooth rod is plugged into the lever insertion hole on the widened corrugated pay-off drum.

[0009] A flat square is arranged at the middle of one end of the lead screw away from the polished rod.

[0010] The diameter of the polished rod is less than or equal to the minor diameter of the lead screw.

[0011] A hexagonal nut is arranged between the mounting cover plate and the flat square on the lead screw, and the hexagonal nut is threadedly connected to the lead screw.

[0012] The total thickness of the installation cover plate is 2-3 mm smaller than the thickness of the driving wheel.

[0013] The installation cover plate is composed of a small flange and a large flange. Both the small flange and the large flange are cylindrical structures. The large flange is fixedly arranged at one end of the small flange, and through holes are evenly distributed on the large flange.

[0014] The driving wheel is provided with a mounting hole matched with the small flange.

[0015] The driving wheel is provided with screw holes ⅠⅡ corresponding to the screw hole Ⅱ.

[0016] The vertical projection of the outer diameter of the large flange on the driving wheel is located inside the inner ring of the driving wheel.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0018] 1) The utility model adopts the installation cover plate and the lead screw as the main structure, which has a simple structure and is easy to manufacture. It can be well used for non-standard widened corrugated pay-off reels, thereby improving the processing capacity of existing equipment;

[0019] 2) By arranging a smooth rod and a flat square at both ends of the lead screw, the threaded end of the installed lead screw can maintain a certain distance from the inner side of the reel frame and the widened corrugated pay-off reel, which prevents the lead screw from being stuck on the inner side of the reel frame and prevents the lead screw from being unable to be screwed out of the installed cover plate due to damage to the lead screw thread. It is easy to use and easy to install and disassemble. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Generally, the components of the embodiment of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0026] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] like Figure 1-2 As shown, the utility model discloses a lever device for a cage stranding machine, which is installed on a widened corrugated pay-off drum 2, and the wide corrugated pay-off drum 2 is installed on a drum rack 1. The two side plates 101 of the drum rack 1 are provided with a bearing seat for controlling the rotation of the corrugated pay-off drum 2 and the rotating disk 3, a friction tension control mechanism 5 and a manual clamping mechanism 6.

[0028] like Figure 3-4 As shown, the utility model provides a lever device for a cage stranding machine, which is mainly composed of a mounting cover plate 401, a hexagonal nut 402, a lead screw 403 and a plurality of hexagon socket head screws for fastening the mounting cover plate 401 of the lever device 4 to the outer surface of the driving wheel 3.

[0029] The mounting cover plate 401 is internally processed with a screw hole 40101, which is threadedly connected to the lead screw 403; the mounting cover plate 401 is composed of a small flange 40102 and a large flange 40103, both of which are cylindrical structures, and the large flange 40103 is fixedly provided at one end of the small flange 40102, and the outer end of the small flange 40102 and the mounting hole 302 of the driving wheel 3 are clearance-matched, and the mounting hole 302 is eccentrically arranged on the mounting cover plate 401; on the circumference of the large flange 40103 of the mounting cover plate 401 There are multiple through holes 40104 of exactly the same size evenly processed in the direction, and clearance fit is adopted with multiple hexagon socket head screws that fasten it to the outer side of the driving wheel 3. The circumferential center lines of each through hole 40104 and the circumferential center lines of each screw hole 301 on the driving wheel 3 completely correspond and coincide with each other; the outer diameter of the large flange 40103 of the installation cover plate 401 cannot exceed the inner ring of the driving wheel 3, and a certain distance should be maintained between the two to facilitate the installation of the cover plate 401 to be fastened to the outer side of the driving wheel 3; the total thickness of the installation cover plate 401 needs to be thicker than that of the belt The thickness of the moving wheel 3 is 2 to 3 mm shorter, which is convenient for installing and disassembling the parts of the lever device 4 and for observing the installation positions of other parts. One end of the lead screw 403 threadedly connected to the mounting cover plate 401 is processed with a light rod 40301 with a diameter less than or equal to the minor diameter of the lead screw 403, which is convenient for screwing in and out of the lead screw 403. The threaded head of the other end of the lead screw 403 threadedly connected to the mounting cover plate 401 is processed with a flat square 40302, which is convenient for installing the lead screw 403 in place by using a special wrench to tighten the hexagonal nut 402 threadedly connected to the lead screw 403. Tightly fastened to the outer side surface of the large flange 40103, it is equivalent to double-fastening the lead screw 403, preventing the lead screw 403 from loosening during normal use, thereby avoiding the occurrence of equipment safety accidents; the threaded end of the installed lead screw 403 should maintain a certain distance from the inner side surface of the wire drum frame 1 on one side, and should also maintain a certain distance from the widened corrugated pay-off drum 2 on the other side, which not only prevents the lead screw 403 from being stuck on the inner side surface of the wire drum frame 1, but also prevents the lead screw 403 from being unable to be screwed out from the installed cover plate 401 due to damage to the thread of the lead screw 403.

[0030] Since the upper end of the side plate 101 of the wire drum rack 1 exceeds the bottom end of the mounting hole 302 of the driving wheel 3 by a certain distance, the screw hole 40101 of the mounting cover plate 401 deviates from the center line of the mounting cover plate 401 by a certain distance, and the outer diameter of the smooth rod 40301 of the screw 403 is smaller than the inner diameter of the lever insertion hole 201 of the widened corrugated pay-off drum 2.

[0031] A plurality of screw holes 301 of identical sizes are processed in the circumferential direction of the mounting hole 302 of the driving wheel 3 , which are threadedly connected with a plurality of hexagon socket head screws that fasten the mounting cover plate 401 to the outer surface of the driving wheel 3 .

[0032] When screwing in or removing the lead screw 403 of the lever device 4, the lever insertion hole 201 of the widened corrugated pay-off reel 2 and the screw hole 40101 of the mounting cover 401 should be rotated to the uppermost end of the vertical center line of the mounting cover 401, which makes it easier to assemble and disassemble the parts of the lever device 4.

[0033] The lever device 4 is only applicable to the production requirements of the widened corrugated pay-off drum 2. Removing the lever device 4 and installing the old lever device will not affect the normal use of the old lever device and the non-widened corrugated pay-off drum.

[0034] As a further improvement of the present invention, if the lead screw 403 of the lever device 4 is made of a high-strength material, the stability and reliability of the lever device 4 during use will be effectively improved.

[0035] When the utility model is installed, it is installed on the outer side of the driving wheel 3. When the widened corrugated pay-off drum 2 is hoisted in, the old lever device needs to be disassembled in advance. After the widened corrugated pay-off drum 2 is installed in place, the lever device 4 is installed. When the widened corrugated pay-off drum 2 is hoisted out, it is only necessary to unscrew the hexagonal nut 402 and the lead screw 403 in advance.
