Abstract
A clamp special for milling a central hole in the tail of a turbine shaft comprises a clamp body and a back disc and is characterized in that the back disc and a machine body are connected into a whole, the clamp body is fixedly connected with the back disc through a bolt, a circular groove and a central through hole are formed in the center of the back disc, a hydraulic tip is horizontally arranged on the center position of the circular groove and the center position of the central through hole, an opening groove is longitudinally formed in the right end face of the clamp body, a wheel shaft of the turbine shaft is horizontally arranged in the opening groove, the rear portion of the hydraulic tip is fixed to a circular positioning block, the circular positioning block is arranged in the circular groove in the back disc, the circular positioning block is in clearance fit with the circular groove, the front portion of the hydraulic tip is exposed out of the central through hole of the back disc, and the front end of the hydraulic tip abuts against the center position of the front end of a wheel head of the turbine shaft. According to the clamp, the coaxiality and perpendicularity of the turbine shaft can be guaranteed, visual inspection is not needed for clamping, accuracy is guaranteed, the work efficiency is improved, weight can be reduced under the circumstance that the turbine head reaches the standard, and the service life of the turbine head is prolonged.
Description
Technical field
The utility model relates to a kind of fixture, particularly relates to a kind of turbine wheel shaft afterbody milling centre bore special fixture.
Background technology
In prior art, to be benchmark adjust by visually observing the perpendicularity of determining wheel head and axostylus axostyle in turbine wheel shaft Yi Luntouwai garden, and milling centre bore has a strong impact on the aequum of turbine wheel shaft.
Utility model content
The purpose of this utility model is exactly the defect existing for overcoming above-mentioned prior art, and a kind of turbine wheel shaft afterbody milling centre bore special fixture is provided.
The technical scheme adopting:
A kind of turbine wheel shaft afterbody milling centre bore special fixture, comprise clamp body and back of the body dish, it is characterized in that described back of the body dish and lathe bed link together, described clamp body is fixedly connected with back of the body dish by bolt, the center of back of the body dish is provided with circular recessed and central through hole, it is top that the center of circular groove and central through hole has been horizontally disposed with hydraulic pressure, on clamp body right side, be longitudinally provided with open slot, the wheel shaft of turbine wheel shaft is horizontally set in open slot, the top rear portion of hydraulic pressure is fixed on a circular locating piece, circular locating piece is arranged in the circular groove of back of the body dish, and circular locating piece and circular groove matched in clearance, the top front portion of hydraulic pressure leans out the central through hole of back of the body dish, its front end is supported the center at turbine arbor wheel head front end, the inwall of turbine arbor wheel head and clamp body right side is fitted tightly.
Advantage of the present utility model:
(1) guarantee turbine wheel shaft axiality, perpendicularity.
(2) clamping, without visually observing, ensures accuracy.
