Spindle device special for valve element machining

Abstract

The invention discloses a spindle device special for valve element machining. The spindle device comprises a centre, a top sleeve, a support, an upper spring, a locating screw, a clamp sleeve, a lower spring, a fixed sleeve, a spindle, a pull rod, a belt wheel and an oil cylinder. At least one valve element part is located on the support at the upper end of the spindle. The centre is connected with the valve element part through the top sleeve. The upper spring is located on the lower portion of the top sleeve. The locating screw is located on one side of the spindle. The clamp sleeve is located on the other side of the spindle. The lower spring is located on the lower portion of the support. The fixed sleeve is located below the support and fixes the spindle. The pull rod is located under the valve element part and partially located in the spindle. The belt wheel is arranged at the bottom of the spindle in a sleeving manner. The pull rod is connected with the oil cylinder. The spindle device can thoroughly solve the problem that valve element parts are clamped to deform by traditional lathe spindle chucks; the valve element part precision requirement is met; the machining percent of pass of the valve element part is improved; automatic clamping of the valve element part is achieved; and the clamping time of the valve element part is saved.

Description

technical field [0001] The invention relates to a spindle device, in particular to a special spindle device for valve core processing. Background technique [0002] At present, the precision of the valve core parts is getting higher and higher, and the straightness of the outer cone surface must be 0.002 mm and the roundness is more than 0.002 mm, and the demand for the valve core parts is very large. The processing machine tool for the outer cone surface of the valve core parts is generally For lathes, since the valve core parts are made of copper and the material is relatively soft, when using the spindle and chuck of a traditional lathe to clamp the valve core parts, the valve core parts are easily deformed, so that the machining accuracy of the parts cannot meet the requirements. The qualified rate of processing is very low. Moreover, due to the use of the spindle device of the traditional lathe, there is a lack of fixtures for automatic clamping of valve core parts, whi...
