Description

TECHNICAL FIELD

[0001] The utility model relates to axle wheel quenching part tray machine tool fixture belongs to axle wheel machining technical field. BACKGROUND

[0002] Wheel axle, as its name implies, is a system composed of wheels and shafts, which can rotate around the coaxial line, equivalent to a lever system with the shaft center as the fulcrum and the radius as the lever, so the wheel axle can change the torque of the torsion, thereby changing the size of the torsion, and the wheel axle is a relatively common metal part, usually made of iron or cylinder material.

[0003] During the production and processing of the wheel axle, the quenching part needs to be quenched. The quenching equipment at the present stage is a high-frequency quenching induction coil, which can quickly realize heating quenching. After searching, it is found that the application No. CN202220850624.2, named camshaft quenching fixture, proposes that the existing technology (CN203451579U) discloses a fixture for camshaft induction quenching positioning tool, which can only fix one camshaft, so that only one camshaft can be quenched at a time, resulting in low processing efficiency. The clamping mechanism is clamped, and the rotating mechanism is rotated to switch, which can complete the replacement of the remaining material during quenching and improve the work efficiency. However, the wheel axle includes a camshaft during quenching of the quenching part, and the quenching part needs to be inserted into the quenching area. Although the application can clamp the camshaft, it cannot move the camshaft, so that the camshaft quenching part cannot be inserted into the quenching area, which is inconvenient to use and can be further improved. At the same time, the application still needs to manually rotate the bidirectional screw rod for clamping and fixing, which is also troublesome and can be further improved.
