Digit Control Machine Tool, in the time of processing work, need to be fixed workpiece by a kind of fixture, so that cutter is processed workpiece.In processing motor housing, use the plain clamp of prior art one end of electric machine casing blank need to be fixed on fixture, the on-fixed end of electric machine casing blank is processed with cutter, after machining one end, retighten again the processing other end, the shortcoming of processing is like this: complex procedures, need the processing operation that twice fixing processing just can complete a motor casing, inefficiency; Mainly in addition also exist crudy low, the stator stationary cylinder at motor casing middle part and the often decentraction of electric motor end cap fixed interface at two ends, error is large; Motor casing end flat and central shaft out of plumb, error is large.Such motor quality is poor, fluctuation of service, and noise is large, and power is low.
Summary of the invention
The object of the invention is to overcome above-mentioned the deficiencies in the prior art, the method for the machining motor shell of numerical control machine that a kind of operating efficiency is high, easy and simple to handle, crudy is good is provided.
Another object of the present invention is in order to realize this method, provide a kind of simple in structure, motor casing is once clamped and is completed processing operation, improve the clamping tool of the machining motor shell of numerical control machine of machining accuracy and motor quality.
Technical scheme of the present invention is achieved in that a kind of method of machining motor shell of numerical control machine, it is characterized in that: motor casing blank is once installed on the clamping tool in the drive shaft of Digit Control Machine Tool, cutting tool for CNC machine once machines the stator stationary cylinder at motor casing middle part, electric motor end cap fixed interface and the end flat at motor casing two ends.
In order to realize said method, the present invention also provides a kind of special clamping tool: a kind of clamping tool of machining motor shell of numerical control machine, it is characterized in that: it comprises a tool base that can be arranged in Digit Control Machine Tool drive shaft, in tool base, there are outward extending lower fixed arm and upper fixed arm, described lower fixed arm is slab construction, in the bilateral symmetry of slab construction, four motor casing pin fixtures are set, at upper fixed arm, motor casing clamping fixture are set.
Described motor casing clamping fixture is, at upper fixed arm, screwed hole of two circular holes is set, two slide bars are installed in two circular holes, fix a pressing plate in the lower end of slide bar, fix rubber blanket below pressing plate, the longitudinal screw bar of extruding pressing plate is installed in screwed hole.
More firm for what motor casing was fixed, described upper fixed arm is slab construction, fixes four longitudinal steel plates in lower fixed arm and the bilateral symmetry of upper fixed arm, and the horizontal thread bar of horizontal extruding fixing motor housing is set on longitudinal steel plate of both sides.
Described horizontal thread bar is four, and four horizontal thread bars are arranged on respectively on the screwed hole of four longitudinal steel plates.
As another kind of scheme, fix a horizontal steel plate at two longitudinal steel plates of the same side, screwed hole is set and horizontal thread bar is installed at the two ends of horizontal steel plate.
The present invention compared with prior art tool has the following advantages: the present invention can once clamp motor casing blank to process at one time, operating efficiency is high, crudy is good, and the axiality of the electric motor end cap fixed interface at two ends is in 0.03mm, and two ends, the center discrepancy in elevation is in 0.05mm.Exclusive clamps holding tool of the present invention, simple in structure, fixed, reliable and stable when work.
