Description

Tee bend valve processingequipment Technical Field The invention relates to the field of valve combination processing, in particular to a three-way valve processing device. Background The three-way valve is used as a core component in a fluid control system, the machining precision of the three-way valve directly determines the sealing performance, the service life and the system operation safety of the three-way valve, particularly the dimensional tolerance, the form and position tolerance and the surface roughness of a sealing surface are required to strictly meet the industry standard, and any machining deviation can cause medium leakage to cause safety accidents or economic losses. However, the three-way valve is limited by a unique T-shaped or Y-shaped inner cavity structure, the processing process of the three-way valve faces a plurality of technical bottlenecks which are difficult to solve for a long time, and the existing processing mode is difficult to match with the high-end equipment manufacturing requirements on high-precision and high-efficiency production of the three-way valve. Firstly, the special-shaped structure of the three-way valve causes natural inconvenience in clamping, positioning and machining operation. Compared with the conventional straight-through valve, the three-way valve is provided with complex inner cavities with multiple paths meeting, the axes of all the interfaces are often distributed in a space staggered manner, and the channels of the inner cavities are narrow and the view field is blocked. The existing clamping tool is of a general structure, is difficult to accurately attach to the irregular shape of the three-way valve, is prone to positioning deviation, uneven stress and the like, can reduce machining accuracy, and can possibly cause indentation or damage to the surface of the valve in the clamping process, so that the follow-up sealing performance is affected. Meanwhile, as the distribution of all machining parts is dispersed, the workpiece posture is required to be frequently adjusted or the tool is required to be replaced in the machining process, the operation is tedious and time-consuming, and the improvement of the machining efficiency is seriously restricted. Secondly, in key processes such as tapping processing, because of the structural characteristics that three-way valve internal pipeline is mutually accessed for the metal piece that produces in the tapping process can't discharge smoothly through conventional mode, very easily detain key positions such as cavity passageway, screw hole or sealed face. And the existing chip removal device is used for processing chips in a mode of directly blowing to one end of the three-way valve, air flow is easy to split or form vortex, chips are dispersed and remained at the corners and thread bottoms of the T-shaped flow channels of the three-way valve, the residual rate is high, and the follow-up machining precision is easy to influence. In addition, the three-way valve is required to be tapped due to the fact that each valve port is required to be tapped, so that when the valve ports are tapped by the existing device, the three-way valve is required to be clamped again by the clamp after tapping is finished each time, accumulated positioning errors can be generated by repeated clamping, and the tapping machining precision of each time is difficult to match. Therefore, a three-way valve processing device needs to be designed.
