Problems solved by technology
For the above-mentioned quenching process, since the workpiece usually has a certain longitudinal height, after quenching an annular zone, the nozzle needs to rise or fall vertically to a certain height to process the next annular zone, which requires a nozzle configuration level The adjustment device and the vertical adjustment device, wherein the horizontal adjustment device is used to adjust the distance between the nozzle and the workpiece surface, and the vertical adjustment device is used to adjust the vertical height of the nozzle. The configuration of the above-mentioned devices complicates the structure of the nozzle, and maintenance High rate, short service life

Embodiment Construction
[0010] In order to further understand the content of the invention, characteristics and effects of the present invention, the following examples are described in detail as follows:
[0011] See figure 1 , the present invention includes a box body 21 with an open top, a support platform 20 is provided in the middle, and a lifting bracket is provided at the edge of the box body 21 . The elevating bracket comprises a third sleeve 18 whose lower end is affixed to the casing 21 and whose top side wall has a radially threaded hole. In the third sleeve 18, an elevating rod 16 is inserted. A third fastening screw 17 is arranged in the hole, and a horizontal plate 1 is affixed to the top of the elevating rod 16 . The box body 21 not only serves as the base of the lifting bracket and the supporting platform 20, but also serves as a collection tank for cooling water to collect the cooling water waste water generated in the quenching process.
[0012] In this embodiment, in order to fac...

Description
technical field [0001] The invention belongs to the technical field of machining equipment, and in particular relates to equipment for quenching the surface of a rotary workpiece. Background technique [0002] In the field of machining, operations often involve hardening the surfaces of large rotating metal parts. In the existing operation mode, large-scale heating and special quenching equipment are generally used. Due to the size and surface shape differences of these equipments, the scope of use of these equipments is narrow, resulting in high cost, which has become a restrictive factor for the surface treatment of large alloy steel rotary workpieces. It is possible to subdivide the surface of large rotating workpieces into ring-shaped strip areas and harden each area separately and step by step. In the prior art, there are rotary support devices and nozzles for quenching that adopt the above-mentioned concept. The operation process is to make the rotary workpieces carr...
