A horizontally-arranged motor stator is fixed to a working table of the machine tool, a hollow rotor is installed in the motor stator in a rotating mode and rotates in cooperation with the motor stator, a chuck is installed on a port in one end of the rotor, machine tool guide rails are arranged on two sides of the motor stator on the machine tool respectively, and the machine tool guide rails are in pilot fit with a left tool rest and a right tool rest respectively, and the left tool rest and the right tool rest are respectively provided with a tool. The end cover machining mechanism is simple in structure and reasonable in design, it is guaranteed that dimension machining in axial and radial directions of the front face and the back face of an end cover type workpiece is completed after the end cover type workpiece is clamped at one time, it is also ensured that coaxiality and bouncing of dimension machining of the front face and the back face of the end cover type workpiece accord with requirements of graph paper, machining precision of a motor end cover is improved, manufacturing quality of a motor is further improved, and production efficiency is improved.
Description
technical field:
The utility model relates generally to numerical control machine tool technique field, relates in particular to a kind of end cap organisation of working of self-driven chuck double tool rest.
background technology:
The degree of protection of motor when IP55 is above, general mounting framework oil sealing or packing ring, its requires end cap (containing the flange end cap) place, shaft extension hole at motor to process installation site; Flange end cap also requires to process flange mounting plane and seam; These sizes all have the requirement of form and position tolerance with the bearing chamber of end cap installed surface and the size of seam.
End cap (containing flange end cap) originally adopted common or numerical-control horizontal lathe processing, and it adopts following processing technology: first process end cap roughly location criterion, with this origin reference location, clamp, bearing chamber, shaft extension hole, the seam of processing end cap installed surface; On lathe, with seam pattern location, secondary clamping end cap has been processed seam again, oil sealing installation dimension, flange mounting plane and the seam (flange end cap) of processing end cap another side.
When seam pattern secondary location clamps, for the ease of installing, what pattern seam and end cap seam adopted is matched in clearance.In use, first process pattern seam, with its seam of centimeter check and plane, beat, then carry out clamping workpiece and processing.Because end cap seam tolerance is js7, pattern seam must be greater than end cap seam size greatest limit deviate; And when long-term use, due to wearing and tearing, its seam fit clearance can be increasing, affects the positioning precision of end cap secondary location; In process, along with the rotation generation centrifugal force of machine chuck, the existence in gap also makes workpiece location produce random skew, thereby affects the precision of electric motor end cap processing.
utility model content:
The utility model object is exactly in order to make up the defect of prior art, and a kind of end cap organisation of working of self-driven chuck double tool rest is provided.It guarantees that end cap completes the whole axial and radial dimension processing on positive and negative two two sides in clamped one time process, guarantees that axiality and the run-out tolerance value of workpiece tow sides processing dimension meets the requirements.
The utility model is achieved through the following technical solutions:
A kind of end cap organisation of working of self-driven chuck double tool rest, it is characterized in that: include lathe, on the workbench of lathe, be fixed with the motor stator of horizontal, in motor stator, be rotatablely equipped with the rotor of hollow, rotor coordinates rotation with described motor stator, and described rotor one end port position is provided with chuck; The both sides that are positioned at motor stator on described lathe are respectively equipped with machine tool guideway, and on described machine tool guideway, guiding is combined with left and right knife rest respectively, on left and right knife rest, is separately installed with cutter.
An end cap organisation of working for chuck double tool rest, is characterized in that: motor stator two ends port is fixed with respectively annular end plate, and the annular inner ring of end plate is rotatablely equipped with rotor by bearing.
Described chuck is pneumatic or the chuck that surges.
The content of this patent innovation:
1, self-driven principle:
Be different from centre numerically controlled lathe in the past---rely on motor driven gear or belt rotating chuck so that workpiece rotary power to be provided, the utility model is by special stator (radial diameter is large, axial dimension is short), large-scale hollow rotor and the combination of chuck, utilize the principle of motor operation, directly drive chuck (rotor) rotation, the required drive that drives workpiece rotation is provided, realizes self-driven.
What 2, between the stator in the utility model and rotor, adopt is that large-scale precision bearing supports and transition structure
Radial diameter is large, axial dimension is short in one of the utility model design, rotor hollow the motor of chuck is installed, motor power is 380V, 50Hz, be arranged on the stage casing of platen, utilize motor operation logic to carry out drive chuck (rotor) rotation, the power that drives workpiece rotation is provided.
3, self-driven clamping structure, clamped one time, double-side cutting:
Pneumatic or the chuck that surges guarantees accurate positioning, reliable clamping.A pair of numerical control double tool rest delivering gear is set on lathe base two side rails, guarantee that workpiece completes its double-edged axial and radial dimension processing in clamped one time process, with this, guarantee that the axiality of workpiece tow sides processing dimension and run-out tolerance value meet drawing requirement, improve the machining accuracy of workpiece, and then improve the workmanship of motor.Improving production efficiency.
End cap (containing flange end cap) is processed by following processing technology: first process end cap roughly location criterion, with this benchmark clamped one time location, oil sealing installation dimension, flange mounting plane and the seam (flange end cap) at the bearing chamber of processing end cap installed surface, shaft extension hole, seam, the back side.
The utility model has the advantages that:
The utility model is simple in structure, reasonable in design, guarantee that end covers workpiece completes the whole axial and radial dimension processing of its tow sides after clamped one time, guarantee the axiality of end cap positive and negative processing dimension and beat to meet drawing requirement, improve the machining accuracy of electric motor end cap, and then improve the workmanship of motor.Enhance productivity.
accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
the specific embodiment:
