Abstract
The utility model relates to a fixing clamp used during processing of metal shafts, in particular to a center device for fixing a metal shaft. The center device is formed by a tapered sleeve, a small center head and a large center head, wherein the back end of the small center head is fixedly connected with the tapered sleeve, and the front portion of the small center head is inserted into a small center head containing cavity arranged in the large center head. The small center head containing cavity is formed by a round back cavity, a connection cavity and a round front cavity which are connected sequentially from back to front. The front section of the large center head is frustum-shaped, and the smallest diameter on the front portion of the large center head is 15-20mm. The center device for fixing the metal shaft has the advantages of being novel in structure, high in processing efficiency and capable of conveniently, accurately and fixedly positioning the metal shaft with the smallest position of a positioning hole at the end of the metal shaft to be 15-20mm.
Description
Technical field
The utility model relates to a kind of metal shaft and adds the stationary fixture that uses man-hour.
Background technology
The both ends of the surface of machine driving axial workpiece are centre bore, and the centre bore pattern has A type, Type B, C type, R type etc., during to the turning of this type of axial workpiece and grinding, need to use stationary fixture that its two ends are fixed.When the size of centre bore is less, aperture, general inner minimum place get final product with general stationary center during less than 5mm, and general stationary center tip diameter is little to be mated with the centre bore inner minimum hole of locating.Due to special instructions for use, some axle classes often two ends are designed with larger reaming, and aperture, general inner minimum place is all more than 15mm, general stationary center can't locate and fix, just can't process, be all at present to adopt the method for edge plug to be fixed processing, and working (machining) efficiency is low.
Summary of the invention
Goal of the invention of the present utility model is the deficiency that exists in order to solve the fixing processing of larger metal shaft of existing aperture, provides a kind of novel structure, the Finial device of fixing metal axle easy to use.
In order to realize above-mentioned goal of the invention, the utility model has adopted following technical scheme:
A kind of Finial device of fixing metal axle, consisted of by coning sleeve, little centre head and large centre head, the rear end of little centre head is fixedly connected with coning sleeve, insert in the interior little centre head container cavity of large centre head the front portion of little centre head, little centre head container cavity is made of the circular back cavity, connection chamber and the circular ante-chamber that are communicated with successively from back to front, circular back cavity diameter is 20mm, and circular ante-chamber diameter is 10mm, and the wall angle of inclination of connection chamber is 60 degree; The front of large centre head is taper type, and the anterior minimum diameter of large centre head is between 15-20mm, and the anterior outer side surface angle of inclination of large centre head is 60 degree.
Adopted the Finial device of a kind of fixing metal axle of technique scheme, be made of coning sleeve, little centre head and large centre head, the rear end of little centre head is fixedly connected with coning sleeve, and insert in the interior little centre head container cavity of large centre head the front portion of little centre head.The advantage of the Finial device of this fixing metal axle is novel structure, the minimum place of locating hole, the metal shaft end metal shaft of aperture between 15-20mm can be facilitated to locate accurately to fix, and working (machining) efficiency is high.

The specific embodiment
Below in conjunction with accompanying drawing 1 and Fig. 2, the utility model is described further.
The Finial device of a kind of fixing metal axle as depicted in figs. 1 and 2 is made of coning sleeve 1, little centre head 2 and large centre head 3.The rear end of little centre head 2 is fixedly connected with coning sleeve 1, insert in the interior little centre head container cavity of large centre head 3 front portion of little centre head 2, little centre head container cavity is made of the circular back cavity 31, connection chamber 32 and the circular ante-chamber 33 that are communicated with successively from back to front, circular back cavity 31 diameters are 20mm, circular ante-chamber 33 diameters are 10mm, and wall 321 angles of inclination of connection chamber 32 are 60 degree; The front of large centre head 3 is taper type, and the anterior minimum diameter of large centre head 3 is between 15-20mm, and anterior outer side surface 34 angles of inclination of large centre head are 60 degree.
During use, the end locating hole of metal shaft 4 is between 15-20mm, and the end locating hole of metal shaft 4 is withstood in the front portion of large centre head 3, and its convenient location accurately is fixing.
