Description

Transformer core winding machine

technical field

The utility model relates to a winding machine, in particular to a transformer iron core winding machine, which belongs to the technical field of mechanical transmission equipment.

Background technique

Transformer is a commonly used electrical equipment. During the operation of the transformer, it is one of the common faults that the inner copper core wire package is damaged. At present, when repairing the copper core wire package of the transformer, it is necessary to stretch the copper core wire in the transformer, remove the damaged section, and then curl the copper core wire into a wire package after repairing for the transformer to reuse . At present, when winding the copper core wire package after repairing, due to the lack of specialized equipment, its operation is very inconvenient, and maintenance personnel usually can only use manual winding to re-roll the copper core wire into a wire package, so that Not only is it laborious to operate, but the efficiency is also very low, and because the copper core wire has a certain hardness, it is difficult to ensure that it is wound evenly when crimping it manually, which leads to a high failure rate of the repaired copper core wire package and a greatly shortened service life. The shortening of the maintenance cycle has further led to an increase in maintenance costs, which has also brought certain pressure to the enterprise.

Utility model content

Aiming at the above-mentioned deficiencies in the prior art, the main purpose of the utility model is to provide a winding machine for conveniently winding transformer copper core wires to form a copper core wire package. It is conducive to improving work efficiency and reducing maintenance costs.

The technical scheme of the utility model is: transformer iron core winding machine, including the bed body of the machine tool, which is characterized in that a motor, a support rod and a positioning frame are installed on the bed body, and a transmission shaft is connected to the output shaft of the motor The free end of the transmission rod is rotatably connected to the support rod, and a first gear shaft for winding the copper core wire is fixed on the transmission rod; a rotatable second gear shaft is installed on the positioning frame, The second gear shaft is parallel to the transmission rod and directly opposite to the first gear shaft. In the utility model, the height of the support rod and the output shaft of the motor is consistent, and the second gear shaft is used to install the copper core wire package to be overhauled, and the first gear shaft is used to wind the copper core wire package after maintenance. There is a certain gap between the first toothed shaft and the second toothed shaft, which is convenient for repairing the damaged copper core wire during maintenance.

In a further technical solution, the first toothed shaft is composed of a cylindrical shaft and baffles fixed at both ends of the shaft, and the length of the shaft is adjustable. Here, the shaft on the first gear shaft is set to be adjustable, the purpose of which is to meet the needs of overhauling copper wire packages of different sizes, and the scope of application is wider.

The utility model has the following beneficial effects:

1. It is convenient to quickly wind the copper core wire: the winding machine of the utility model is driven by a motor to realize automatic winding forming without manual operation, which obviously improves the working efficiency of winding, and the operation is also very simple .

2. Reduced maintenance cost: Since the winding time is greatly shortened, and the winding uniformity of the repaired wire package is better, this is beneficial to prolong the service life of the product and reduce the maintenance cost.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further:

As shown in Figure 1, the transformer iron core winding machine of the present utility model comprises the bed body 1 of machine tool, is installed with motor 2, support bar 3 and positioning frame 4 on bed body 1, on the output shaft of described motor 2 A transmission rod 5 is connected to the top, and the free end of the transmission rod 5 is rotatably connected to the support rod 3 . Here the output shaft of the motor 2 is substantially at the same height as the top of the support rod 3, so that the transmission rod 5 can be in a horizontal position to facilitate its movement. A first pinion 6 for winding the copper core wire is also fixed on the transmission rod 5; the first pinion 6 is composed of a cylindrical shaft and baffles fixed at both ends of the shaft, The length of the shaft is adjustable, and the function of the baffles on both sides of the shaft is to limit the wound copper core wire between the two baffles, so that the thickness of the formed copper core wire package can be controlled. A rotatable second pinion shaft 7 is installed on the positioning frame 4 , and the second pinion shaft 7 is parallel to the transmission rod 5 and faces the first pinion shaft 6 . The function of the second gear shaft 7 is to install the copper core wire package 8 to be overhauled. During operation, the first gear shaft 6 drives the second gear shaft 7 to rotate through the wound copper core wire. When the transmission rod 5 is installed, a bearing can be installed earlier on the support rod 3, and the transmission rod 5 is connected with the support rod 3 through the bearing, so that the free rotation of the transmission rod 5 can be realized. Of course, other connection methods can also be used, such as clearance fit of the steel ring and the like.

Working principle: First wrap the copper core wire to be overhauled on the second gear shaft 7 on the positioning frame 4, and wind the end of the copper core wire wrapped on the wire on the first gear shaft 6, so that the second pinion The first pinion shaft 6 and the second pinion shaft 7 are connected through copper core wires. After the installation is completed, the motor 2 is turned on, the motor 2 drives the transmission rod 5 to rotate, and the transmission rod 5 synchronously drives the first gear shaft 6 to rotate. When the first pinion 6 rotates, the copper core wire is gradually wound on the shaft of the first pinion 6 , and at the same time, the copper core wire on the second pinion 7 is gradually unfolded. When a section of copper core wire damaged on the copper core wire package is exposed, the motor is suspended, and the damaged part is repaired by the maintenance personnel, and then the motor is turned on, so that the copper core wire on the second gear shaft 7 is finally transferred to the first gear. On the gear shaft 6, a new copper core wire package is formed. After overhaul is finished, the first pinion 6 is taken off from transmission rod 5 and gets final product, after a new gear shaft is installed on transmission rod 5, can carry out the overhaul of next copper core wire bag again.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model rather than limit the technical solutions. Although the applicant has described the utility model in detail with reference to the preferred embodiments, those skilled in the art should understand that those Any modification or equivalent replacement of the technical solution of the present utility model without departing from the purpose and scope of the technical solution shall be covered by the claims of the utility model.
