Problems solved by technology
[0002] There are basically two ways to place the gear sleeves of thin-walled cars during carburizing: flat-packed on a general-purpose tray or puncture-mounted, but both ways have certain defects that cause a The pass rate of the workpiece after quenching is low
The main reason is that it is difficult to guarantee the ellipticity of the workpiece when it is hung, and it is difficult to control the flatness of the workpiece when it is flat mounted, so the overall heat treatment cost will be high.
[0003] Faced with the above problems, the current manufacturer has proposed a tool for placing the workpiece. The tool can support the workpiece to maintain the flatness of the plane during carburizing and quenching, and solve the problem of the workpiece during quenching to a certain extent. However, this tool basically cannot Adapt to various types of workpieces, so the cost of quenching processing will not be reduced much

Embodiment Construction
[0028] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] A carburizing and quenching device for a gear sleeve of a synchronizer, which includes a quenching tool 2 and a support frame 3 for placing the quenching tool 2 .
[0030] The quenching tool 2 includes a tool base 24 and a tool boss 23 positioned on the upper surface of the tool base 24, the tool base 24 and the tool boss 23 can be cylindrical, and the tool boss 23 is located on the tool base 24 in the middle of the upper surface, and the diameter of the tooling boss 23 is smaller than the diameter of the tooling base 24, so it can form an inverted T-shaped; through the tooling base 24 and the tooling boss 23, there is a liquid hole 25, the through Liquid hole 25 and described frock base 24 and frock boss 23 concentric center line, on the outer wall of described frock base 24 evenly have several threaded holes 22 perpendicular to frock ...

The invention provides a carburizing and quenching device for a synchronizer gear sleeve. The carburizing and quenching device comprises a quenching tool, wherein the quenching tool comprises a tool base and a tool boss located on the upper surface of the tool base; a liquid through hole is formed in the tool base and the tool boss; a plurality of threaded holes which are vertical to the central line of the tool base and are located on the same reference plane with the tool base are uniformly formed in the outer side wall of the tool base; the reference plane is parallel to the bottom of the tool base; and each threaded hole is internally provided with a screw in screw thread fit with the threaded hole, and the length of the screw is larger than the aperture of the threaded hole. By using the carburizing and quenching device, the planeness and roundness of a quenched workpiece can be effectively ensured, meanwhile, various types of workpieces can be adapted, the production cost is greatly reduced, and meanwhile the production efficiency is also increased.
