Abstract
The utility model relates to a gasoline engine crankshaft journal quenching device, which comprises a quenching coil, a positive electrode plate, a negative electrode plate, a left sprinkler head, a right sprinkler head, a left sprinkling pipe and a right sprinkling pipe. An insulation cushion is arranged between the positive electrode plate and the negative electrode plate, and a heat conducting strip is disposed on the semicircular quenching coil and adhered to the inner arc surface of the quenching coil. The quenching device is capable of quenching a whole journal including a round corner portion of the connecting position of a crankshaft and a crank, thereby greatly increasing gasoline crankshaft quality, and improving fatigue strength of the crankshaft by a large margin.
Description
Technical field
The utility model relates to the thermal treatment unit of mechanical component, particularly to the quench bent neck quenching device of gasoline engine crank of usefulness of the bent neck of gasoline engine crank.
Background technology
At present, when the revolving parts such as Qu Jing to gasoline engine crank carry out quench treatment, all be to adopt to have utilized the quenching device of inductive heating principle to carry out, quenching device comprises quenching coil, positive electrode plate, negative electrode plate, left sprinkler head, right sprinkler head, left water jet standpipe and right water jet standpipe, positive electrode plate, negative electrode plate and quenching coil are generally made by red copper, it forms a circuit loop, and the quenching coil is semi-round ring shape, is provided with insulating mat between the positive and negative electrode plate.When the axle journal that adopts this quenching device to bent axle quenches, the angle part, garden of bent neck of bent axle and crank junction can not obtain quench treatment, thereby cause Crankshaft Fatigue Strength not high, generally fracture just occurs, had a strong impact on the quality of bent axle less than 1,000,000 times.
The utility model content
The purpose of this utility model provides the bent neck quenching device of a kind of gasoline engine crank, and when the bent neck to gasoline engine crank quenched, the angle part, garden of bent neck of bent axle and crankshaft crank junction can access quench treatment.
The bent neck quenching device of gasoline engine crank described in the utility model, comprise quenching coil, positive electrode plate, negative electrode plate, left sprinkler head, right sprinkler head, left water jet standpipe and right water jet standpipe, be provided with insulating mat between the positive and negative electrode plate, the quenching coil is semi-round ring shape, the quenching coil is provided with conducting strip, and conducting strip is fitted in the interior arc-shaped surface of quenching coil.
Conducting strip can be tin plate, the utility model is owing to be fitted with conducting strip on the interior arc-shaped surface on the quenching coil, when the big electric current of high frequency is flowed through this quenching coil, will be in the quenching coil the superpower flux of polarization instantaneous variation, this superpower flux comprises perforation on whole bent neck of the angle part, garden of bent neck of bent axle and crank junction, thereby portion produces extremely strong eddy current within it, make bent neck and be able to rapid rising with the temperature of the angle part, garden of crank junction, on a left side, after right sprinkler head is sprayed water to it, just realize bent neck and with the quench treatment of the angle part, garden of crank junction.
The bent neck quenching device of bent axle described in the utility model is because can be to comprising whole bent neck enforcement quench treatment of the bent neck of bent axle and the angle part, garden of crank junction, thereby greatly improved the quality of gasoline engine crank, Crankshaft Fatigue Strength is greatly improved, and surpasses 1,000 ten thousand times and fracture also can not occur.
Description of drawings
Now in conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 1 is the schematic top plan view of the bent neck quenching device of gasoline engine crank described in the utility model;
Fig. 2 is the sectional view of A-A line among Fig. 1.
