Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of transformer coil production, in particular to a winding die fixing device for transformer coil production. Background Technique
[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core. The quality of the winding of the transformer coil is directly related to the performance of the transformer. In the traditional transformer coil winding technology. In the traditional winding device, it is necessary to sleeved the winding die on the winding rotating shaft. However, in order to facilitate the installation of the winding die on the winding rotating shaft, there will be a certain gap between the two after connection. This existing gap will cause relative displacement between the winding die and the winding rotating shaft during the winding process, ultimately affecting the quality of the coil winding. And because the winding rotating shaft rotates at a high speed during winding, the existence of the gap causes continuous relative friction between the winding die and the winding rotating shaft, resulting in wear of the winding die and the winding rotating shaft, reducing their service life.

[0028] Please refer to Figures 1-7 a wire winding die fixing device for transformer coil production shown in the figure, which includes an outer frame 1 and an adjusting mechanism 2, and the adjusting mechanism 2 is arranged inside the outer frame 1.
[0029] The outer frame 1 is provided with a connecting plate 1a, a connecting shaft end 1b, and a support plate 1c. There are two support plates 1c, and one end of the two support plates 1c is fixedly connected to the connecting plate 1a, and the other end is fixedly connected to the connecting shaft end 1b. The connecting plate 1a is connected to the turbine reducer of the rotary power providing device on the external equipment.
[0030] The adjusting mechanism 2 includes a set of outer plates 2a symmetrically arranged up and down and a main support plate 2b disposed between the two outer plates 2a. A plurality of outer sliders 2c are provided on each outer plate 2a, and inner sliders 2d matching with the outer sliders 2c are provided on the upper and lower surfaces of the main support plate 2b. The outer sliders 2c and the inner sliders 2d are both in a shape similar to a right trapezoid, and the inclined surfaces of the outer sliders 2c and the inner sliders 2d are in contact with each other.
[0031] A tension spring 2e is further provided between the two outer plates 2a. The two ends of the tension spring 2e are respectively connected to the two outer plates 2a. When the coil winding work is completed, the telescopic rod of the external cylinder retracts. At the same time, the outer plates 2a are pulled back by the tension of the tension spring 2e therebetween, facilitating the removal of the wound workpiece. The outer frame 1 further includes limit blocks 1d, and a plurality of limit blocks 1d are provided on each outer plate 2a. The limit blocks 1d are provided to play a limiting role. Specifically, when the outer sliders 2c and the inner sliders 2d move, the fixed limit blocks 1d play a limiting role to avoid excessive adjustment. The limit blocks 1d are also connected to the outer plates 2a through pin shafts and bolts.
[0032] A spring 2f is further provided at one end of the main support plate 2b close to the connecting shaft end 1b. One end of the spring 2f is fixedly connected to the main support plate 2b, and the other end is fixedly connected to the connecting shaft end 1b. The side of the main support plate 2b away from the connecting shaft end 1b is connected to the telescopic rod of the external cylinder. A plurality of tension springs 2e are evenly provided between the two outer plates 2a. A set of springs 2f is provided, and a plurality of waist-shaped holes 2g are further provided on the main support plate 2b. The waist-shaped holes 2g are provided to facilitate the installation of the tension springs 2e. Since the telescopic rod of the cylinder is not effectively connected to the main support plate 2b when the telescopic rod of the cylinder retracts, the telescopic rod of the cylinder cannot pull back the main support plate 2b. At this time, the main support plate 2b needs to be reset by the elastic force of the two springs 2f, thereby promoting the two outer plates 2a to also fall back, so as to achieve the purpose of adjustment.
[0033] Specifically, the limit blocks 1d and the outer sliders 2c are arranged on the same surface of the outer plate 2a, and the limit blocks 1d and the support plate 1c are connected by bolts.
[0034] Specifically, the number of the outer sliders 2c is the same as that of the inner sliders 2d.
[0035] Working principle: When working, the operator installs the winding die on this device, and then the external cylinder works to push the telescopic rod to move the main support plate 2b forward. At this time, the inner slider 2d pushes the outer slider 2c to generate an upward force. Since the limit block 1d and the outer side plate 2a are connected by a pin bolt, the left-right movement of the outer side plate 2a is restricted, and at this time, the outer side plate 2a can move in the up and down directions. Thus, the purpose of clamping against the winding die is achieved. At this time, the tension spring 2e is in a stretched state, and the spring 2f is in a compressed state.
[0036] When it is necessary to remove the workpiece after winding is completed, the cylinder telescopic rod retracts and disengages from one end of the main support plate 2b. At this time, the tension spring 2e uses the tensile force and at the same time the spring 2f uses the elastic force to reset the main support plate 2b and the two outer side plates 2a, facilitating the disassembly of the workpiece.
[0037] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present utility model, the present utility model can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.

Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
