Description

Anti-deformation tool for thermal treatment of locking washer

Technical Field

The utility model belongs to the technical field of spare part manufacturing, especially, relate to a locking washer spare thermal treatment is with shape frock of preapring for an unfavorable turn of events.

Background

The traditional operation method for heat treatment processing of parts is to disperse the parts in a material tray, then push the parts into a heat treatment furnace, preserve heat to finish thickness, and then perform water quenching or oil quenching to finish heat treatment. However, the following disadvantages are mainly present in this working method: (1) after each heat treatment and water quenching or oil quenching, the deformation of the part is large, the part needs to be manually corrected again, and the machining efficiency is low; (2) parts are easily lost due to their loose distribution. The sizes of the parts are not easy to be ensured under the above conditions, and the qualified rate of the parts is low.

SUMMERY OF THE UTILITY MODEL

Not enough to prior art exists, the utility model provides a locking washer spare thermal treatment is with shape frock of preapring for an unfavorable turn of events.

An anti-deformation tool for heat treatment of a locking washer piece comprises a base, a shaft and a top cover, wherein a threaded hole is formed in one end face of the shaft, a counter bore is formed in the base, and the shaft is fixed on the base through a bolt; the side surface of the shaft is provided with a groove matched with the bulge of the inner ring of the locking washer to be thermally treated along the height direction, and the locking washer to be thermally treated is sleeved on the shaft; the top cover is provided with a through hole with the same appearance as the shaft, is sleeved outside the shaft and abuts against the tail end of a locking washer to be thermally treated sleeved on the shaft; the top cover and the base are locked and fixed through a double-headed bolt.

And four threaded holes are machined in one end face of the shaft.

Four counter bores corresponding to the threaded holes are correspondingly machined in the base.

Three grooves matched with the bulges of the inner ring of the locking washer to be thermally treated are formed in the side surface of the shaft along the height direction.

The beneficial effects of the utility model are that: the utility model provides a tool clamp with a brand new structure, which can prevent the deformation of parts caused by heat treatment every time, and make the processing of the parts convenient and easy; the size of the part is ensured, and the processing efficiency of the heat treatment of the locking washer piece is improved; the time for manually correcting the parts is saved, and the number of the parts is ensured.
