Problems solved by technology
During the initial installation, manual debugging is used to ensure that the cutting edge is parallel to the busbar. This method is not only time-consuming and laborious, but also difficult to guarantee accuracy.
The angle deviation will have a serious impact on the radius of the blunt circle of the working edge during the processing of the parts, which will directly affect the product qualification rate. At present, this process device lacks a set of devices for accurately controlling the angle between the turning tool and the spool busbar

Disclosed is an included angle precision positioning device for a turning tool cutting edge and a valve element. The included angle precision positioning device is characterized by comprising a three-dimensional moving platform, a manual rotating table, a turning tool clamping assembly, a spectral confocal displacement sensor and a monocrystal diamond turning tool which are arranged on a machine tool body and connected in sequence, wherein the valve element to be treated is fixedly arranged on the machine tool body through two centers of a machine tool and directly faces the cutting edge of the monocrystal diamond turning tool. The included angle precision positioning device has the advantages of structural modularization, high reconfigurability, high control precision and the like, the auxiliary process time can be greatly shortened, the production cost is reduced, and the product percent of pass is increased.
Description
technical field [0001] The invention relates to a technology in the field of high-precision machining, in particular to a precision positioning device for the angle between the cutting edge of a turning tool and a valve core. Background technique [0002] The electro-hydraulic servo valve is the core component of the servo control execution system. It converts and amplifies the electrical signal into a hydraulic signal through the cooperation of the valve core and the valve sleeve. The requirements are extremely high, the radius of the blunt circle is less than 0.5 μm, and the height of the burr is less than 1 μm. In the prior art, deburring equipment is installed on a special grinding machine to process the working edge of the valve core, but the angle between the cutting edge of the diamond turning tool and the busbar of the valve core has not been considered during the installation of the deburring equipment. During the initial installation, manual debugging is used to e...
