Abstract

The invention relates to a gate valve rod screw processing single purpose machine, which is characterized in that the machine mainly comprises a rack, a transmission mechanism, a main shaft case body fixedly connected with the rack, the main shaft provided with a blade plate, a spring clip and a pitch contour hollow shaft, wherein the main shaft provided with the blade plate supports the bearing of the main shaft case body, and the main shaft is connected with a motor via the belt transmission; the taper of the front end of the spring clip is matched with the taper of the front end mouth of the pitch contour hollow shaft, and the spring clip passes through the pitch contour hollow shaft the back end of which is connected with a locking nut. The invention has the advantages that the machine meets the processing requirement of small-size civil gate valve rod screw, the semi-automatic production is realized, and the production efficiency is very high. The operation workers only put the valve rod into the spring clip to tightly clamp the valve rod, and then the acme thread of the valve rod can be molded at one time.

Description

technical field [0001] The invention belongs to special equipment for valve production, in particular to a special machine tool for thread processing of a gate valve stem. Background technique [0002] The trapezoidal thread processing of the gate valve stem is generally done by lathe turning. Low production efficiency. For the large-scale valve stem, the whirl milling machine is used for milling and forming. Although the production efficiency is improved, the processing cost is also increased. Especially for small-sized civil gate valves, the market demand is large, and the requirements of high production efficiency and low production cost must be met in order to adapt to the competitive situation in the market. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned technologies, and provide a special machine tool for gate valve stem thread processing, which can realize semi-automatic production and...
