Thread machining device of valve upper cover machining line

Abstract

The invention discloses a thread machining device of a valve upper cover machining line. The thread machining device comprises a supporting bottom plate, a worktable, a rotating seat and a lead screw,the worktable is arranged on the supporting bottom plate, the rotating seat is arranged on one side of the worktable, the lead screw is arranged in the rotating seat, a lifting body is arranged on the lead screw, an operation panel is arranged on the side edge of the lifting body, operation buttons are arranged on the operation panel, a motor is arranged on the upper portion of the lifting body,a gearbox is arranged on the lower portion of the motor, an input shaft and an output shaft are arranged in the gearbox, and a gear is arranged on the input shaft. The thread machining device has theadvantages that two clamping cylinders are arranged, a valve upper cover can be fixed onto the worktable and then drilled and tapped, the influence of looseness of a workpiece in the machining processon machining quality is avoided, the procedures of drilling and tapping are finished by clamping once, and workpiece transfer time is saved.

Description

technical field [0001] The invention relates to the related technical field of valve body upper cover processing, in particular to a thread processing device of a valve body upper cover processing line. Background technique [0002] The valve body is one of the main parts of the valve. There are different mechanical manufacturing methods according to the pressure level, such as casting, forging, etc. The valve body of the medium and low pressure specifications is usually produced by casting process, and the valve body of the medium and high pressure specifications is forged. Process production, can effectively withstand medium pressure after forming a seal together with the valve core and valve seat sealing ring. The definition of "valve" is a device used to control the direction, pressure, and flow of fluid in a fluid system. A valve is a device that allows the medium (liquid, gas, powder) in the piping and equipment to flow or stop, and can control its flow. The device an...
