Description

Technical Field

[0001] The utility model relates to a quenching device, in particular to an integral quenching device for a planetary carrier shaft, belonging to the technical field of metal heat treatment devices. Background Art

[0002] The planet carrier is one of the main components of the planetary gear transmission, and the planetary gear shaft or bearing is installed on the planet carrier. When the planetary gear is used as a basic component, it is the part that bears the largest external torque of the mechanism. At present, it is also one of the most important equipment in engineering equipment.

[0003] The planetary carrier shaft integral quenching device currently disclosed is CN212894833U, comprising a quenching box, a mounting seat and a rotating sleeve, a movable screw is sleeved on the bottom of the quenching box, a cylinder is fixedly installed on the top of the slider, movable plates are sleeved on both sides of the inside of the mounting seat, a first connecting plate is fixedly installed on the end of the top of the movable plate away from the mounting seat, a fixing rod is fixedly installed on the side of the top of the first connecting plate close to the mounting seat, an arc-shaped clamping plate is fixedly installed on the side of the fixing rod away from the first connecting plate, adjusting screws are sleeved on both ends of the inside of the rotating sleeve, a driven gear is fixedly installed on the outside of the rotating sleeve, and a driving gear is meshed with the bottom of the driven gear.

[0004] In the above scheme, the device that fixes the workpiece is pushed upward by the cylinder, so that the workpiece penetrates into the high-frequency copper coil and heats up at a high speed. After the heating is completed, the cylinder contracts and the workpiece is put into the water for quenching. However, this method of adjusting the upper and lower positions of the workpiece by the cylinder is not appropriate. If the cylinder works in the water for a long time, water will enter, which will cause the cylinder to fail to operate, reducing the practicality of the device. Utility Model Content
