Fast clamping device for valve machining

Abstract

The invention discloses a fast clamping device for valve machining. The device comprises a machine tool table, a jack is fixedly connected to the middle portion of the upper side of the machine tool table, a first V-shaped iron part is fixedly connected to the top of the jack, and a machined valve is placed on the first V-shaped iron part; vertical square steel bars are fixedly connected to the periphery of the machine tool table, guiding rails are arranged between the front and rear vertical square steel bars respectively, a horizontal square steel bar is arranged between the two guiding rails, a hydraulic oil cylinder is fixedly connected to the middle portion of the horizontal square steel bar, and a second V-shaped iron part is fixedly connected to the lower end of the hydraulic oil cylinder. The device has the advantages that 1, the machining precision of the valve can be stably guaranteed, by means of the fast clamping device, the valve is clamped, the position precision of the valve relative to a tool and a machine tool is guaranteed by a clamp, and the machining precision of the same valve or a same batch of valves is basically the same; 2, the working efficiency is improved, and fast and convenient clamping can be conducted by the fast clamping device, so that clamping labor-hour of the valve is significantly reduced.

Description

technical field [0001] The invention relates to the technical field of valve processing, in particular to a quick clamping device for valve processing. Background technique [0002] With the rapid development of the processing and manufacturing industry, machining at home and abroad has developed to a relatively mature stage, and the rapid clamping and positioning of workpieces on machine tools has become an indispensable part of machining. Driven by the development of , intelligence and environmental protection, machine tool fixtures are also developing in the direction of high precision, high efficiency, modularity, combination, general purpose and economy. [0003] 1) In order to improve the production efficiency of machine tools, there are more and more fixture products for double-sided, multi-sided and multi-piece clamping. In order to reduce the clamping time of workpieces, various self-centering fixtures, pneumatic and hydraulic fixtures, and quick clamping devices C...

[0006] 4) The appearance of valve three-end surface processing tooling greatly facilitates the processing of valves, but a kind of valve three-end surface processing tooling at the present stage has many deficiencies, for example, the fixing stability is poor, the processing is more troublesome, and the three end surfaces need to be processed. Clamping three times, low processing efficiency
