Description

Technical Field

[0001] This utility model belongs to the field of cable manufacturing technology, and more specifically, it relates to a bundle tension adjustment structure for cable assembly. Background Technology

[0002] In the wire and cable bundling process, a swing-arm type wire bundling tension adjustment structure is usually used to ensure that the tension of multiple fine wires remains consistent during the twisting process to form a bundle, thereby ensuring the electrical performance, mechanical strength and appearance quality of the bundled products.

[0003] Based on the above, in order to ensure the stability of the swing arm movement and improve the tension adjustment accuracy of the cable during the operation of the swing arm tension adjustment structure, the operator usually needs to lubricate the swing arm shaft regularly. When lubricating the swing arm, because the swing arm is in continuous dynamic swinging during equipment operation, the operator is at great risk of getting their hand caught when approaching the work. At the same time, manual lubrication is prone to improper lubrication due to differences in experience or operational negligence: if there is too much oil, the grease will overflow and contaminate the single wire and the equipment shell, and it is also very easy to damage the adhesion of the cable insulation layer; if there is too little oil, the shaft will be insufficiently lubricated, which will directly affect the stability of the swing arm operation. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a bundle tension adjustment structure for cable bundling. This structure solves the problem that, during the operation of a swing-arm type bundle tension adjustment structure, to ensure the stability of the swing arm's movement and improve the tension adjustment accuracy of the cable, operators typically need to periodically lubricate the swing arm shaft. However, during lubrication, because the swing arm is continuously oscillating while the equipment is running, operators are at high risk of hand injury when approaching it. Furthermore, manual lubrication is prone to improper lubrication due to differences in experience or operational negligence: too much oil will cause grease to overflow and contaminate the individual wires and the equipment casing, and can easily damage the adhesion of the cable insulation layer; too little oil will result in insufficient lubrication of the shaft, directly affecting the stability of the swing arm's operation.

[0005] The purpose and effect of this utility model's bundle tension adjustment structure for cable assembly are achieved through the following specific technical means:

[0006] A tension adjustment structure for cable bundling includes an adjustment base, a swing arm body, an electric actuator, a swing arm shaft, an oil reservoir, and a lubrication auxiliary mechanism. The swing arm body is located on the upper side of the front end face of the adjustment base; the electric actuator is located on the lower side of the front end face of the adjustment base; a piston rod is slidably connected to the upper end of the electric actuator; the outer end of the piston rod is hinged to the swing arm body; the swing arm shaft is rotatably connected to the inner end of the adjustment base, and the front end of the swing arm shaft is fixedly connected to the swing arm body; a lubrication auxiliary mechanism is provided on the rear end face of the swing arm shaft. Positioning auxiliary components; the oil reservoir is located on the upper side of the inner end of the adjusting base; an oil replenishment pipe is fixedly connected to the outer end of the oil reservoir, and an air inlet plug is provided at the lower end of the oil replenishment pipe; a sealing plug is threaded to the top of the oil replenishment pipe; an oil level gauge is fixedly connected to the lower end of the inner side of the sealing plug; a draining auxiliary cylinder is connected to the outer end of the oil reservoir through a delivery pipe; the draining auxiliary cylinder is sleeved on the outside of the swing arm shaft, and multiple oil draining holes are evenly arranged on the inner side of the draining auxiliary cylinder; the lubrication auxiliary mechanism is located between the oil reservoir and the swing arm shaft.

[0007] Furthermore, a sealing auxiliary cover is coaxially and fixedly connected to the front end face of the rocker arm shaft; a sealing auxiliary ring is fixedly connected to the inner end face of the sealing auxiliary cover; a spline shaft is coaxially and fixedly connected to the front end face of the positioning auxiliary component; a spline groove is opened at the rear end of the rocker arm shaft; and the spline shaft is inserted into the inner side of the spline groove.

[0008] Furthermore, a support ring is fixedly connected to the outer side of both the front and rear end faces of the drainage auxiliary cylinder; the support ring is rotatably connected to the swing arm shaft.

[0009] Furthermore, the lubrication auxiliary mechanism includes: a force-bearing support plate, which is slidably disposed on the outside of the oil reservoir; a connecting bracket is fixedly connected to the outer side of the top end face of the force-bearing support plate, the connecting bracket being a U-shaped frame structure; a pusher piston plate is fixedly connected to the bottom end face of the connecting bracket, the edge of the pusher piston plate being in contact with the inner wall of the oil reservoir; and an elastic reset member is fixedly connected between the connecting bracket and the adjusting base.

[0010] Furthermore, the lubrication auxiliary mechanism also includes: two drive cams, which are rotatably mounted on the left and right sides of the upper end of the force-bearing support plate, respectively. The outer ends of the drive cams are pressed against the force-bearing support plate, and the force-bearing support plate and the drive cams together constitute a cam transmission mechanism. A transmission pulley is coaxially fixedly connected to the front end face of the drive cam. A synchronous belt is wound around the outer side of the transmission pulley. Multiple toothed structures are circumferentially arranged and fixedly connected to the outer end of the transmission pulley, and multiple toothed grooves that mesh with the toothed structures are opened on the inner side of the synchronous belt.

[0011] Furthermore, the lubrication auxiliary mechanism also includes: a drive gear and a transmission gear, wherein the drive gear is coaxially fixedly connected to the outer end of the positioning auxiliary component; the transmission gear is coaxially fixedly connected to the outer side of the left-end drive cam; the drive gear and the transmission gear mesh with each other, and the number of teeth of the drive gear is greater than the number of teeth of the transmission gear.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When in use, the utility model achieves fully automatic lubrication through the lubrication auxiliary mechanism, eliminating the need for operators to have close contact with the moving parts, greatly avoiding the risk of mechanical pinching. At the same time, the sealing plug of the oil tank and the threaded connection structure of the oil replenishment pipe avoid spillage and contact safety issues when manually adding grease, significantly improving the safety factor of production operations.

[0014] In use, the oil level in the oil tank can be monitored in real time by the oil level gauge inside the sealing plug. In conjunction with the linkage mechanism between the pusher piston plate and the drive cam, the amount of lubricating oil discharged can be precisely controlled according to the operating state of the swing arm shaft. The oil discharge holes evenly distributed inside the draining auxiliary cylinder ensure that the lubricating oil is evenly coated along the circumference of the shaft. This not only avoids single-line contamination, reduced adhesion of the insulation layer and dirt on the equipment shell caused by excessive oil, but also prevents problems such as shaft wear and unstable swing arm operation caused by insufficient oil, thus significantly improving lubrication efficiency and equipment service life.

[0015] In use, this invention employs a double-sealing structure formed by the sealing auxiliary cover at the front of the swing arm shaft and the inner sealing auxiliary ring, effectively preventing lubricating oil from overflowing from the front end of the shaft and further reducing the risk of contamination. The positioning auxiliary component is engaged with the spline groove of the swing arm shaft via a spline shaft, which not only ensures the coaxiality and stability of the shaft during rotation but also simplifies the assembly and disassembly process, facilitating later maintenance. The support auxiliary rings at both ends of the drain auxiliary cylinder are rotatably engaged with the swing arm shaft, ensuring the fixation of the drain auxiliary cylinder without affecting the normal operation of the shaft, thus improving the overall structural stability.

[0016] In use, the lubrication auxiliary mechanism uses the rotation of the swing arm shaft as the power source. The drive gear drives the transmission gear to rotate through the drive gear, and then drives the double cam to rotate synchronously through the transmission pulley and the synchronous belt. This drives the pusher piston plate to deliver lubricating oil. This design does not require an additional power device, saving energy. Moreover, the lubrication action is synchronized with the swing arm operation, and the lubrication frequency can be automatically adjusted according to the actual working state of the equipment to meet the needs of different filament production conditions.

[0017] In use, this invention ensures smooth operation of the swing arm shaft through precise lubrication, effectively maintaining the stability of the swing arm's movement. This, in turn, guarantees the uniformity of tension when multiple fine wires are twisted together. This not only improves the electrical performance and mechanical strength of the wire bundle products but also optimizes the product's appearance quality, reduces defects such as wire diameter deviation and surface scratches caused by uneven tension, and lowers the defect rate. At the same time, automated lubrication reduces operational errors caused by manual intervention, shortens downtime for maintenance, and improves production continuity and efficiency.
