Embodiment Construction

[0009] The high-frequency induction heating puller includes a top rod 2 and a hook 4 connected with the top rod 2, and also includes a set of high-frequency induction heaters 3, and one end of each high-frequency induction heater is equipped with a magnet. In this specific embodiment, the ejector rod 2 is in the form of a jack 1. The high-frequency induction heater 3 adopts existing products.

[0010] When in use, first adsorb the high-frequency induction heater 3 on the surface of the disassembled part 5. According to the size of the surface of the disassembled part or the requirements of the heating speed, adsorb a corresponding number of high-frequency induction heaters, and then install the puller On the disassembled part 5, properly push out the jack-type ejector rod 2 to properly pre-energize, and then connect the high-frequency induction current to quickly heat the outer surface of the disassembled part, and the shaft 6 of the disassembled part basically keeps the temperat...

Abstract

The invention relates to a screw extractor, in particular to a high frequency induction heating screw extractor. The invention solves the problem that the existing screw extractor is hard to disassemble some shaft fastening pieces with tight fit. The high frequency induction heating screw extractor comprises a mandrel and a falcula connected with the mandrel and also comprises a group of high frequency induction heaters, wherein a magnet is arranged on one end of each high frequency induction heater. Compared with the traditional screw extractor, the heating device is added on the high frequency induction heating screw extractor of the invention; and the gaps between the parts to be disassembled can be increased by heating so as to greatly reduce the friction force between the parts to be disassembled, largely increase the drawing ability of the screw extractor and protect the parts to be disassembled and the personal safety of the site operation personnel.

Description

Technical field [0001] The invention relates to a puller, specifically a high-frequency induction heating puller. Background technique [0002] Puller is also called ejector, which is widely used to dismantle various couplings, gears, bearings, belt pulleys and other shaft fastening parts. It consists of ejector rod and hook claw connected (or hinged) with ejector rod. , The ejector rod is divided into two types: screw and jack, and the hook is divided into two-jaw and three-jaw. When in use, the hook is used to grab the object to be pulled, and the screw-type ejector rod is rotated or the jack-type ejector rod is ejected. Make the ejector rod move forward steadily, and the claw hook will move back accordingly to pull out the object being pulled. [0003] Existing pullers are very convenient and effective in disassembling the fastening parts on some loosely matched shafts. However, it is sometimes very difficult to disassemble the fastened parts on some tightly matched shafts, esp...
