Description of the embodiments
The utility model is further described below with reference to the accompanying drawings.
As shown in fig. 1-4, two connecting plates 1 are arranged at intervals, one connecting pipe 2 is arranged on the outer side of each connecting plate 1, two ends of an induction coil 4 are respectively connected with the two connecting pipes 2, the induction coil 4 comprises a journal heating section 4-1 and an inner wall heating section 4-2, a magnetizer 1 is arranged on one side of the journal heating section 4-1, and a magnetizer 2 5-2 is arranged on one side of the inner wall heating section 4-2.
An insulating plate 3 is arranged between the two connecting plates 1. For preventing contact short-circuits between the two connection plates 1.
The connecting pipe 2 and the induction coil 4 are hollow structures, and a water gap 1-1 is arranged on one side of the connecting plate 1. The cooling water passes through the water gap 1-1 of the two connecting plates 1 to take away the heat of the induction coil 4, so as to prevent the induction coil 4 from being burnt and deformed.
The journal heating section 4-1 is in a straight line, the cross section of the magnetizer I5-1 is U-shaped, and a U-shaped notch is opposite to the journal part of the crank section.
The inner wall heating section 4-2 is arc-shaped and is positioned at two sides of the journal heating section 4-1, the section of the magnetizer II 5-2 is U-shaped, and a U-shaped notch is inclined outwards and is opposite to the joint of the journal and the inner wall.
The two sides of the induction coil 4 are respectively provided with a fastening plate 6, and the fastening plates 6 are connected through a screw rod 6-1. For maintaining the shape of the induction coil 4, so that the distance from the induction coil 4 to the crankshaft 8 can be maintained to secure the induction heating effect, preventing the induction coil 4 from contacting the workpiece.
Positioning blocks 7 are arranged on two sides of the crankshaft 8, and center holes 7-1 concentric with the shaft necks of the crank sections are arranged on the outer sides of the positioning blocks 7.
When the quenching machine is used, the centers on two sides of the quenching machine tool are propped against the center holes 7-1 of the positioning blocks 7 on two sides of the crankshaft 8, and as the center of the center hole 7-1 is concentric with the center of the journal, the crank section rotates by taking the journal as the center during rotation, and the crank section is uniformly heated.
The induction coil 4 is provided with a journal heating section 4-1 and an inner wall heating section 4-2 which respectively heat the outer circle and the inner wall of the journal, the sections of the first magnetizer 5-1 and the second magnetizer 5-2 are U-shaped, and the U-shaped groove is opposite to the processing part. Under the notch effect of the magnetizer, the circuit only flows through the conductor surface at the opening of the magnetizer, and the high-frequency alternating current flowing through the conductor surface layer carries out induction quenching on the crank section under the action of the skin effect.
