The utility model discloses a gear shaft quenching work fixture which comprises a top cover and a seat body, wherein the top cover comprises a cover plate, top fixing pieces, a top cover through hole and fixed columns; the seat body comprises a gear shaft wall, bottom fixing pieces, positioning holes, a seat body through hole and a base; the top cover and the seat body are connected by the fixed columns of the top cover through the positioning holes of the seat body; the cover plate is respectively and fixedly connected with the top fixing pieces and the fixed columns; the top cover through hole is formed in the cover plate; the base is respectively connected with the gear shaft wall and the bottom fixing pieces; and the positioning holes and the seat body through hole are formed in the base. According to the gear shaft quenching work fixture disclosed by the utility model, the seat body can be connected with an external motor, and the whole fixture can be rotated, so that each part of a gear shaft can be heated uniformly, the strength and the rigidity of the gear shaft can be improved after quenching, and the gear shaft is more durable.
Description
Technical field
The utility model relates to a kind of gear shaft anchor clamps, and particularly a kind of gear shaft quenching frock clamp belongs to field of machining.
Background technology
In the processing of gear shaft, quenching is a thermal treatment process, it mainly is that steel is heated to critical temperature Ac3(hypoeutectoid steel) or the Ac1(hypereutectoid steel) above temperature, insulation for some time, in rapid cooling, make supercooled austenite carry out martensite or bainite transformation, obtain martensite or bainite structure, cooperate the tempering with differing temps then, with intensity, hardness, wear resistance, fatigue strength and the toughness etc. that significantly improve steel, thereby satisfy the different service requirementss of various mechanical component and instrument.
In the quenching process of gear shaft, anchor clamps are important tool of fixed gear shaft, and the anchor clamps of existing gear shaft quenching usefulness can not well allow gear shaft evenly heat, and just stiff after anchor clamps are fixing, are unfavorable for the circulation heating of gear shaft.
