Abstract

The invention discloses a fixed clamping device for machining a gate valve sealing cover. The device comprises a support chassis, a first longitudinal bracket, a second longitudinal bracket, a chuck,a locking bolt, an auxiliary shifting block, a height adjusting mechanism, an inner supporting plate and a circumferential adjusting device. According to the device, the height adjusting mechanism isarranged on the first longitudinal bracket and the second longitudinal bracket, so that the inner supporting plate can be driven to move up and down between the first longitudinal bracket and the second longitudinal bracket after turning a steering wheel, then the position of the chuck at the upper end of the inner supporting plate is adjusted, and the adjustment of the position of a clamped workpiece is facilitated; meanwhile, the circumferential adjusting device is arranged, and the chuck can be connected through a driven gear under the driving of a motor, so that the chuck can be driven torotate, and the circumferential angle adjustment of the clamped workpiece can be carried out during the machining; and a rotary cutter is used for machining, the flexibility is high, machining is convenient, and the working efficiency is improved.

Description

technical field

[0001] The invention relates to the field related to the processing of gate valve components, in particular to a fixed clamping device for processing the sealing cover of a gate valve. Background technique

[0002] The gate valve is a gate of the opening and closing part. The direction of movement of the gate is perpendicular to the direction of the fluid. The gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. It is widely used in petrochemical, pipeline transportation and other industries. On various water supply and gas supply pipelines, it plays the role of controlling the circulation and closing of the medium in the pipeline. It has the characteristics of small flow resistance, flexible opening and closing, long life, compact structure, safety and reliability.

[0003] Existing gate valves are usually divided into upper and lower parts, the upper part is the steering wheel, valve stem, plunger and other structures, ...
