Abstract

The invention discloses an inner hole clamp for a workpiece for high-frequency induction heating. The inner hole clamp comprises a support plate and arc-shaped quartz plates installed on the support plate, wherein the support plate comprises a base and a support beam; the base and the support beam form an angle of 90 degrees; a mounting table protruding out of a mounting surface is arranged at oneend, away from the base, of the support beam; mounting holes are formed in the mounting table; the arc-shaped quartz plates are fixedly connected with the mounting table of the support beam; and a plurality of arc-shaped quartz plates form a circular structure and are attached to an inner hole of a workpiece. Through the arrangement of the overall structure of the clamp, the requirement for the strength of the clamp is met, and the whole clamp cannot generate an electric spark to affect the product quality, and has great practical significance and economic value.

Description

technical field [0001] The invention belongs to the technical field of industrial machinery, and more specifically relates to a workpiece inner hole fixture for high-frequency induction heating. Background technique [0002] Induction heating equipment is a kind of three-phase power frequency alternating current, rectified into direct current, and then the direct current into an adjustable current, supplying the alternating current flowing through the capacitor and the induction coil, generating high density in the induction coil The magnetic line of force, and cut the metal material contained in the induction coil, a large eddy current is generated in the metal material. [0003] In actual production, workpieces with inner holes need to be positioned and clamped in the process of high-frequency induction heating. The commonly used method is to use stainless steel inner hole fixtures, but this kind of fixtures are easy to conduct electricity and cause electric ignition, whic...
