Description

Technical Field

[0001] This utility model relates to the technical field of winding structures, and in particular to a winding structure for steel cords used in aircraft tires. Background Technology

[0002] Traditional tires use fibers as the skeleton material, while new tires use steel cords as the skeleton material. Compared with nylon cords, steel cords have become an ideal candidate material for the reinforcement structure of aircraft tires due to their high strength, high modulus and excellent fatigue performance.

[0003] Currently, among the equipment used for winding steel cord, such as the patent with announcement number CN222118489U, this utility model relates to a winding structure for steel cord used in tires, including a base, a workbench fixedly connected to the top of the base, a tilting box fixedly connected to the top of the workbench, the tilting box being symmetrically distributed with respect to the center line of the workbench, a drive shaft being provided inside the tilting box, a first electric telescopic rod being fixedly connected to the end of the drive shaft, a clamping plate being fixedly connected to the end of the first electric telescopic rod, and a winding roller being abutted between the clamping plates. This utility model can drive the cleaning plate to move by setting a second electric telescopic rod.

[0004] In the use of the existing structure, it has been found that after the steel cord on the winding roller is wound, it is not convenient to remove the winding roller, which increases the complexity of operation and reduces work efficiency. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a winding structure for steel cord used in aircraft tires that improves the convenience of winding steel cord, improves the ease of removing the winding cylinder, reduces the difficulty of operation, and improves work efficiency.

[0006] This utility model discloses a winding structure for steel cord used in aircraft tires, comprising a base and a support base, with the support base positioned at the top of the base. It also includes a lifting device, a driving device, a positioning mechanism, a winding cylinder, and a limiting frame. A semi-circular groove is provided at the top of the support base, and the two sides of the winding cylinder are rotatably placed on the semi-circular groove of the support base. The limiting frame is mounted on the base via the lifting device, which drives the limiting frame to move up and down. A semi-circular groove is provided at the bottom of the limiting frame. The driving device is located on the base and drives the winding cylinder to rotate. A positioning mechanism is provided on the winding cylinder to fix the ends of the steel cord. The winding cylinder is placed on the support base... The support base is positioned on a semi-circular groove. A lifting device then moves the limiting frame downwards, allowing it to fit over the upper part of the winding drum. This allows the support base and limiting frame to rotate and limit the winding drum, improving the stability of the steel cord during winding. The front end of the steel cord is fixed to the winding drum via a positioning mechanism. When the drive device rotates the winding drum, it winds up the steel cord, improving the ease of winding. After winding, the lifting device moves the limiting frame upwards, separating the drive device from the winding drum, thus improving the ease of removing the winding drum, reducing operational difficulty, and increasing work efficiency.

[0007] Preferably, the driving device includes a guide rail, a base, a chuck, a first motor, and a push cylinder. The guide rail is mounted on the base, and the base is slidably mounted on the guide rail. The chuck is rotatably mounted on the outer wall of the base. The first motor is mounted on the outer wall of the base, and its output end is connected to the chuck. The push cylinder is mounted on the outer wall of the base, and its moving end is connected to the base. When the winding cylinder is placed on the support, the push cylinder pushes the base to move, causing the base to move the chuck's jaws to the side of the winding cylinder. Then, the chuck clamps and fixes the winding cylinder. The first motor drives the chuck to rotate, causing the chuck to rotate and wind the steel cord.

[0008] Preferably, the positioning mechanism includes a guide post, a spring, a limiting ring, a side plate, and a groove. The guide post is slidably mounted on the winding cylinder, the limiting ring is disposed on the outer wall of the guide post, the spring is fitted onto the outer wall of the guide post, the side plate is mounted on the front end of the guide post, and the groove is disposed on the outer wall of the winding cylinder. The front end of the steel cord is wound around the front end of the guide post, and then the spring provides a pushing force to the limiting ring, causing the limiting ring to drive the guide post to slide, causing the guide post to drive the side plate to embed into the groove, thereby pressing and fixing the front end of the steel cord with the side plate. When the winding cylinder rotates, the steel cord is wound around the winding cylinder.

[0009] Preferably, it also includes a first guide member and a guide sleeve. The first guide member is installed on the outer wall of the base, and the guide sleeve is slidably installed on the first guide member. By allowing the steel cord to pass through the inside of the guide sleeve, when the steel cord is wound on the winding drum, the guide sleeve is moved back and forth to guide the steel cord to be wound evenly on the winding drum.

[0010] Preferably, it also includes a reciprocating screw and a second motor. The reciprocating screw is rotatably mounted on the inner side wall of the first guide member, and the guide sleeve is screwed onto the reciprocating screw. The second motor is mounted on the outer side wall of the first guide member and connected to the reciprocating screw. The second motor drives the reciprocating screw to rotate, so that the reciprocating screw drives the guide sleeve to move back and forth.

[0011] Preferably, the lifting device includes a second guide member, which is installed on the outer wall of the base. The limiting frame is slidably installed on the second guide member by being driven up and down by an electric cylinder. The lifting and lowering movement of the limiting frame by the electric cylinder improves the convenience of limiting the winding cylinder.

[0012] Preferably, a semi-circular bearing is provided in the semi-circular groove of the support base and the limiting frame; this improves the smoothness of the winding cylinder rotation and reduces wear.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the winding cylinder is placed on the semi-circular groove of the support base, and then the lifting device drives the limiting frame to move downward, so that the limiting frame is fitted onto the upper part of the winding cylinder through the semi-circular groove, thereby enabling the support base and the limiting frame to cooperate in limiting the rotation of the winding cylinder, improving the stability of the steel cord when winding on the winding cylinder. The front end of the steel cord is fixed on the winding cylinder by the positioning mechanism. When the driving device drives the winding cylinder to rotate, the winding cylinder winds up the steel cord, thereby improving the convenience of winding the steel cord. After the steel cord is wound, the lifting device drives the limiting frame to move upward and separates the driving device from the winding cylinder, thereby improving the convenience of removing the winding cylinder, reducing the difficulty of operation, and improving work efficiency.
