Abstract

The invention relates to an automatic tapping machine for valve-connected nut of sluice valve, which is characterized by mainly consisting of a bed body, a main axis provided with a workpiece clamping mechanism, a transmission, as well as a middle carriage and a small carriage which are respectively fixed with an air cylinder; the small carriage is fixedly provided with a tool rest; the tool rest is fixedly provided with a tool; the main axis is supported on a headstock and is connected with the transmission mechanism. The automatic tapping machine for valve-connected nut of sluice valve has the beneficial effects of being suitable for producing common civil sluice valve, being capable of reducing the cost, improving the work efficiency, and adapting the demand of very low market price. 4,500 nuts can be produced for worker in single shift.

Description

technical field [0001] The invention belongs to special equipment for processing valves, in particular to an automatic tapping machine for connecting nuts of gate valves. Background technique [0002] When processing the valve joint lock nut of the gate valve body screw connection, four processes of expanding the center hole, turning the end face, turning the inner hole and turning the inner thread are required. The processing of valves and lock nuts has always been processed by lathes. The processing procedures are cumbersome and the labor productivity is very low. Especially for common civil gate valves, the market sales price is very low. In order to reduce costs and improve labor efficiency, it is urgent to develop a special equipment for processing valve joint lock nuts. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned technologies, and provide an automatic tapping machine for valve nuts of...
