DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Please see the attached Figure 1-3 , a high-frequency quenching positioning tool, comprising:

[0023] The box body 1 has no cover and a console 10 is provided on its side wall;

[0024] Functional part 2, the functional part 2 includes an electric hydraulic column 20 and multiple magnetic coils 21. The lower end of the electric hydraulic column 20 passes through the multiple magnetic coils 21 and is fixedly connected to the bottom of the box 1. The multiple magnetic coils 21 are fixedly connected to the inner wall of the box 1. The electric hydraulic column 20 and the multiple magnetic coils 21 are electrically connected to the console 10;

[0025] The fixing part 3 includes a base plate 30 and a fixing assembly 31 . The base plate 30 is fixedly connected to the upper end of the electric hydraulic column 20 , and the fixing assembly 31 is fixedly connected to the middle position of the base plate 30 .

[0026] During specific use, the electric hydraulic rod 20 is raised through the console 10. In theory, it only needs to be higher than the vertical position of the magnetic coil 21. The specific height can be determined according to one's own working habits. The ring forging is placed on the base plate 30, and then the gear 313 is driven to rotate by rotating the adjustment handle 314, and the arc plate 312 is driven to move through the kneading connection between the gear 313 and the connecting tooth plate 311. The purpose of fixing it is achieved by the contact between several evenly distributed arc plates 312 and the inner ring of the ring forging. In this process, the position of the ring forging can also be calibrated. The centers of the ring forging and the magnetic coil 21 are on the same vertical straight line. It is worth noting that in the present invention, the electric hydraulic rod 20 and the magnetic coil 21 are both controlled in stages by the console 10. For example, magnetic coils 21 of different diameters correspond to different contraction heights of the electric hydraulic stem 20.

[0027] Specifically, the fixing assembly 31 includes a central cylinder 310, a plurality of connecting tooth plates 311, a plurality of arc-shaped plates 312, a gear 313 and an adjusting handle 314. The central cylinder 310 is provided with a special-shaped cavity 3100. The gear 313 is located at the center of the special-shaped cavity 3100. The adjusting handle 314 penetrates the central cylinder 310 and is fixedly connected to the gear 313. The adjusting handle 314 is movably connected to the central cylinder 310. The plurality of arc-shaped plates 312 are evenly distributed on the outside of the central cylinder 310. One end of the tooth plate 311 is located in the special-shaped cavity 3100, and the other end is fixedly connected to the arc plate 312, and the connecting tooth plate 311 is meshed with the gear 313; the rotation of the gear 313 in the central cylinder 310 is controlled by the outer adjustment handle 314, thereby adjusting the position of the arc plate 312, thereby positioning and fixing the ring forging. It should be noted that the fixing component 31 is fixedly connected to the base plate 30, wherein the fixing component 31 determines the lower limit of the inner hole of the ring forging, and the diameter of the base plate 30 determines the upper limit of the inner hole of the ring forging.

[0028] Specifically, the number of the connecting tooth plates 311 is the same as the number of the arc plates 312 , and at least two groups are provided. The provision of at least two groups can ensure that the arc plates 312 can complete the positioning and fixation of the ring forging.

[0029] Specifically, the multiple magnetic coils 21 have different radii, and their radii decrease from top to bottom; the different radii of the magnetic coils 21 correspond to ring forgings of different sizes, so that the magnetic coils 21 do not need to be replaced when changing different molds, thereby indirectly improving work efficiency.

[0030] Specifically, the box 1 is filled with coolant 12, and the height of the coolant 12 is less than the height of the magnetic coil 21; the heating and cooling processes of the mold are completed directly in the box 1, without the need to move it to other containers for cooling after heating. This method can not only ensure the quality of quenching, but also effectively shorten the time required for quenching.

[0031] Specifically, a waterproof protective cover 200 is provided on the side wall of the electric hydraulic column 20 and is fixedly connected thereto; considering that a portion of the electric hydraulic column 20 is in the coolant, waterproof measures are necessary to prevent water from entering the electric hydraulic column 20.

[0032] Specifically, a drain pipe 13 is provided on the side wall of the box body 1 , and the drain pipe 13 is provided with a plug 130 movably connected thereto; liquid is discharged through the setting of the drain pipe 13 .

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
