Abstract
The utility model relates to a local induce heating surface quench induction coil detecting device of shake arm shaft type accessory. The device has characteristics in that: the device includes a pedestal, a checking shaft, a checking block and a connection block. One end of the checking shaft connects with the pedestal, the checking shaft diameter is less than inner diameter of the checked induction coil, blocking groove is designed on spaced position of the checking shaft corresponding to various group induction coils; the checking block parallel to the checking shaft connects with the checking block fitted with the blocking groove, the checking block length is in accordance with axial length of spaced position of various group induction coils. The detecting device provided by the utility model can check and regulate axial position, size, radial size of the induction coil through a device, and has simple structure, is convenient to detection, and has high efficiency.
Description
Technical field
The utility model belongs to the heat treatment technics field, is specifically related to be used for the detection technique of induction coil of the local induced surface hardening of rocking arm axial workpiece.
Background technology
Motor rockshaft high-frequency induction heating surface heat is handled, and is all very high to case depth and hardened zone width requirement.This is just to shape, the size of employed induction coil, comprise and weighshaft between radius clearance require than higher.Common employed induction coil is formed by the copper pipe coiling, because its intensity, rigidity are all poor, in use or keeping process, be easy to deform, cause the position of weighshaft heating quenching and size and hardness are not met technical requirements, even producing strikes sparks burns because of contacting with induction coil to make weighshaft, finally causes and reprocesses even product rejection.Correct in order to guarantee to the position and the size of weighshaft heating quenching, traditional method is at each verification experimental verification that carries out when producing beginning, adjust shape, the size of induction coil again according to experimental result, and the cycle is long, efficient is low, and cause product rejection easily, make weighshaft production cost height.
Summary of the invention
The purpose of this utility model is at existing technology above shortcomings, provide a kind of collect measurer, instrument in together can be directly to shape, the size of induction coil, comprise and weighshaft between the gap check, gauged frock, overcome long, inefficient shortcoming of traditional method cycle.
The technical solution of the utility model is as follows:
A kind of local induced surface hardening induction coil proofing unit of rocking arm axial workpiece, it includes pedestal, school inspection axle, school inspection piece and contiguous block.The end that its lieutenant colonel examines axle is connected on the pedestal, and the diameter of school inspection axle is less than the internal diameter of detected induction coil, has designed draw-in groove respectively in interval location corresponding position on the school inspection axle and between each group of induction coil.Be connected with the check block that cooperates with draw-in groove on the contiguous block parallel with the verification axle, the axial length of interval location is consistent between each group of the length of check block and induction coil.
Described each check block is made up of a deck and two card arms, and the consistent arch groove of cylindrical with school inspection axle is arranged on the deck, and two are blocked arms and are connected and fixed the arch groove both sides, cooperates with draw-in groove on the verification axle.
This device links together when using when high-ranking officers examine axle and pedestal, forms radially school checking device, is connected and fixed by contiguous block when high-ranking officers examine piece, and cooperates with school checking device radially, with regard to axial inspection, the correction device of feasible one-tenth.
The utility model can be realized axial location, size to induction coil by a device, and radial dimension checks respectively, proofreaies and correct, and is simple in structure, easy to detect, the efficient height.

Embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the induction coil school checking device shown in this figure is to be used for motor rockshaft high-frequency induction heating surface heat to handle, and to shape, the size of employed induction coil, comprises that the gap between induction coil and the weighshaft is checked, proofreaies and correct.It includes pedestal, school inspection axle, contiguous block and examines pieces by the school that a deck and two card arms are formed.The end that its lieutenant colonel examines axle 2 is connected on the pedestal 1, the diameter of school inspection axle 2 is less than the internal diameter of detected induction coil 6, designed draw-in groove 7 respectively in interval location corresponding position on the school inspection axle 2 and between induction coil 6 each group, be connected with the check block that cooperates with draw-in groove 7 on the contiguous block 3 parallel with verification axle 2, the axial length of interval location is consistent between each group of the length of check block and induction coil.Each check block is made up of a deck 5 and two card arms 4, has the arch groove 8, two consistent with the cylindrical of school inspection axle 2 to block arm 4 on the deck 5 and is fastened on the arch groove both sides, cooperates with draw-in groove 7 on the verification axle.
During use, high-ranking officers examine axle 2 and pass induction coil 6, utilize several school inspection pieces to examine cooperating of axle draw-in groove with the school, and the axial location of induction coil 6 is checked, proofreaied and correct; In addition, utilize the radius clearance between school inspection axle 2 and the induction coil 6, can check, proofread and correct, thereby guaranteed radius clearance between induction coil and weighshaft the right alignment of induction coil.
