[0002] The iron core is used in transformers. The role of the iron core in the transformer is the main channel of the magnetic circuit. The iron core will greatly enhance the magnetism.

[0003] During the production process, the iron core needs to be cut according to the actual required size of electromagnetic components such as transformers. The cut iron core will not affect the characteristics of the iron core itself, but will also greatly improve the magnetic flux density and saturation density during operation. In order to improve the stability of the existing cylindrical iron core during cutting, it is usually clamped with a clamp. However, the existing iron core clamp structure is too simple. A clamp can only be used with iron cores of the same outer diameter and cannot adapt to iron cores of different diameters, which limits its use. Utility Model Content

DETAILED DESCRIPTION

[0024] like Figure 1-Figure 6 As shown, the utility model provides a technical solution: a clamp for iron core processing, including a positioning table 1, two groups of supporting feet 2 are fixedly installed on the bottom of the positioning table 1, and an arc-shaped positioning seat 3 is fixedly installed on the top of the positioning table 1. By setting the arc-shaped positioning seat 3, columnar iron cores with different outer diameters can be placed, and the inner wall of the arc-shaped positioning seat 3 is fixedly installed with an anti-skid pad 4. By setting the anti-skid pad 4, the friction between the arc-shaped positioning seat 3 and the outer wall of the columnar iron core can be increased. A clamping mechanism 5 is provided on the positioning table 1. By setting the clamping mechanism 5, columnar iron cores with different outer diameters can be clamped, which is more convenient to use.

[0025] The above-mentioned clamping mechanism 5 includes an inclined rail 51, a rotating shaft 52, a cross universal shaft 53, a forward and reverse motor 54, a clamping plate 55, a screw 56, a worm 57, a worm wheel 58, and a rubber pad 59; the inclined rail 51 is fixedly installed on the inner wall of the positioning platform 1, and the angle between the inclined rail 51 and the positioning platform 1 is 120°. There are four inclined rails 51, and the four inclined rails 51 are arranged in groups of two on both sides of the arc-shaped positioning seat 3. The inner wall of the inclined rail 51 is slidably connected with a clamping plate 55. Under the guiding action of the inclined rail 51, the two groups of clamping plates 55 can be tilted and moved downward, so that the two groups of clamping plates 55 and the arc-shaped positioning seat 3 can clamp and position the columnar iron core at three points, and thus the columnar iron cores of different diameters can be clamped and positioned. The lower surface of the clamping plate 55 is fixedly installed with a rubber pad 59. The rubber pad 59 can be used to increase the friction between the clamping plate 55 and the outer wall of the columnar iron core. The inner wall of a group of inclined rails 51 located on the left side of the arc-shaped positioning seat 3 is rotated. The screw rod 56 is rotatably connected, and the outer wall of the screw rod 56 is threadedly connected to the inner wall of the clamping plate 55. The rotation of the screw rod 56 can drive the clamping plate 55 threadedly connected thereto to slide up and down on the inner wall of the inclined rail 51. The rotating shaft 52 is rotatably connected to the upper surface of the supporting foot 2 located on the left side of the positioning platform 1. A worm gear 58 is fixedly installed on the outer wall of the rotating shaft 52. A forward and reverse motor 54 is fixedly installed on the upper surface of the supporting foot 2 located on the left side of the positioning platform 1. A worm 57 is fixedly installed on the output end of the forward and reverse motor 54. The worm 57 is meshed with the worm gear 58. The forward and reverse motor 54 is started to drive the worm 57 to rotate. The rotation of the worm 57 and the worm gear 58 meshed therewith can drive the two sets of rotating shafts 52 to rotate synchronously. One side of the cross universal joint 53 is hinged at the top of the rotating shaft 52, and the other side of the cross universal joint 53 is hinged at the bottom of the screw rod 56. When the rotating shaft 52 rotates, the screw rod 56 can be driven to rotate synchronously by using the cross universal joint 53.

[0026] The above-mentioned clamping plate 55 is provided with a positioning mechanism 6 that adapts to the special-shaped iron core. The positioning mechanism 6 can clamp the special-shaped iron core. The positioning mechanism 6 includes a threaded rod 61, a knob 62, and a rubber block 63; the threaded rod 61 is threadedly connected to the inner wall of the clamping plate 55, and the threaded rod 61 passes through the clamping plate 55. There are two groups of threaded rods 61. The positions of the conical barrel-shaped iron core with different outer diameters are positioned by the two groups of threaded rods 61 in cooperation with the rubber block 63, so that the conical barrel-shaped iron core can be clamped. A knob 62 is fixedly installed at one end of the threaded rod 61, and a rubber block 63 is fixedly installed at the other end of the threaded rod 61. The threaded rod 61 is rotated by the knob 62, so that the threaded rod 61 drives the rubber block 63 to move downward until the rubber block 63 is tightly fitted to the outer wall of the conical barrel-shaped iron core.

[0027] Working principle: first place the cylindrical iron core on the arc-shaped positioning seat 3, and then start the forward and reverse motor 54 to drive the worm 57 to rotate. The rotation of the worm 57 and the worm wheel 58 meshing with it can drive the two sets of rotating shafts 52 to rotate synchronously. While the rotating shaft 52 rotates, the cross universal joint 53 can drive the screw rod 56 to rotate synchronously. The rotation of the screw rod 56 can drive the clamping plate 55 threadedly connected to it to slide downward on the inner wall of the inclined rail 51 until the clamping plate 55 is tightly attached to the outer wall of the cylindrical iron core. At this time, the cylindrical iron core is positioned and fixed by the arc-shaped positioning seat 3 and the two sets of clamping plates 55, and the cylindrical iron cores of different diameters can be clamped and positioned by tilting and moving the two sets of clamping plates 55 downward, which greatly improves the overall practicality of the device.

[0028] When encountering an irregular columnar iron core, such as a conical barrel-shaped iron core, first place the conical barrel-shaped iron core on the arc-shaped positioning seat 3, and rotate the threaded rod 61 through the knob 62 to make the threaded rod 61 drive the rubber block 63 to move downward until the rubber block 63 fits tightly against the outer wall of the conical barrel-shaped iron core, so that the conical barrel-shaped iron core fits tightly against the outer wall of the arc-shaped positioning seat 3. By positioning the positions of the conical barrel-shaped iron core with different outer diameters through two sets of threaded rods 61 and the rubber block 63, the conical barrel-shaped iron core can be clamped, which is more convenient to use.

[0029] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
