Technical Field

[0001] The utility model relates to the technical field of intermediate frequency inductor processing, in particular to a special clamp for facilitating welding of intermediate frequency inductors. Background Art

[0002] As a commonly used equipment in the quenching process of super-large bearing rings, the medium-frequency inductor has the characteristics of high heating efficiency, good quenching quality, simple structure, solid and durable; therefore, it is the main component in the quenching process and has a wide range of application prospects. The principle is to put the metal part in an induction coil, pass alternating current through the induction coil, generate an alternating electromagnetic field, and induce an alternating current in the metal part. Due to the skin effect, the current is mainly concentrated on the surface of the metal part, so the surface temperature is the highest. Water spray cooling or other cooling follows under the induction coil. Since heating and cooling are mainly concentrated on the surface, the surface modification is very obvious, while the internal modification is basically non-existent, which can have a very special heat treatment effect.

[0003] The structure of existing sensors is that a copper tube is wound into a spiral shape, one end is pulled out from the center of the spiral, and led out side by side with the other end, and then the two ends of the copper tubes are welded. In actual applications, the spiral copper tube needs to be fixed, but due to the different diameters of the copper tube spiral, different specifications of clamps are required to fix it, which brings inconvenience to use.

[0017] See also Figure 1-2 The utility model provides a technical solution: a special clamp for welding a medium frequency sensor, comprising a base 1, a slider 2 and a clamp seat 3, wherein the base 1 is configured as a square plate as a whole, and a slide groove 11 is arranged on the base 1; the slide groove 11 is distributed along the diagonal of the square on the upper surface of the base 1, the slider 2 is matched with the slide groove 11, and the slider 2 moves along the length direction of the slide groove 11; the clamp seat 3 is fixedly installed on the upper surface of the slider 2, the clamp seat 3 is configured as a square strip structure, and the clamp seat 3 is configured perpendicular to the base 1; a clamp groove 31 is arranged in the clamp seat 3, the clamp groove 31 is configured as a U-shaped groove, and the axial direction of the clamp groove 31 is perpendicular to the sliding direction of the slider 2.

[0018] Furthermore, a screw rod 12 is installed in the slide groove 11, and the screw rod 12 is driven by a servo motor embedded in the base 1; a thread hole is correspondingly opened on the slider 2, and the screw rod 12 passes through the thread hole.

[0019] Furthermore, rolling grooves 13 are provided on the surface of the base 1 on both sides of the slide groove 11, and limiting plates 22 are provided on both sides of the slider 2. Balls are embedded in the lower part of the limiting plates 22. The balls are correspondingly stuck in the rolling grooves 13 and roll along the rolling grooves 13.

[0020] Furthermore, a connecting plate 21 is disposed on the upper surface of the sliding block 2 , and fixing plates 32 are disposed on both sides of the bottom of the clamping seat 3 . The fixing plates 32 are fixedly connected to the connecting plate 21 by bolts 33 .

[0021] Furthermore, a sleeve 4 is symmetrically arranged on the upper surface of the base 1 , and a telescopic rod 41 driven by a hydraulic cylinder is installed in the sleeve 4 ; a supporting plate 42 is arranged on the top of the telescopic rod 41 , and a plurality of partitions 43 are arranged at intervals on the supporting plate 42 .

[0022] Working principle: In actual use, the servo motor drives the screw rod 12 in the slide 11 to rotate, and the screw rod 12 engages with the thread hole of the slider 2, thereby achieving the purpose of driving the slider 2 to move; the slider 2 moves along the slide 11 with the clamp 3, and the screw rods 12 in the four slides 11 keep working synchronously, so that the four groups of sliders 2 and the clamp 3 also move inward and outward synchronously. The four slides 11 are distributed along the diagonal lines of the square, so that the four groups of sliders 2 are at four points of the same circle when moving, so as to match the spiral copper tubes of different specifications of the intermediate frequency sensor.

[0023] The clamping groove 31 on the clamping seat 3 is arranged in an axial direction perpendicular to the sliding direction of the slider 2, so that the copper tube can be clamped in the clamping groove 31. By adjusting the position of the clamping seat 3, the copper tube can be clamped and fixed from the inside or outside to ensure the stability of the structure during welding.
