Abstract
A blank cap type motor housing processing fixture relates to a tool fixture for processing motors. The blank cap type motor housing processing fixture comprises a core rod, a locking nut and an expansion ring, wherein, a cone body corresponding to an inner cone hole is arranged at the left part of the core rod, and external screw threads are formed at the central part of the core rod; a cone body with a small diameter facing rightwards is arranged at the right part of the core rod, and a tube-shaped body extends on the right end surface of the cone body; a central through hole is formed on the core rod; the excircle of the expansion ring is cylinder-shaped; a circular ring disc extends on the excircle at the left end part of the expansion ring; the inner circle of the expansion ring is a cone hole; a plurality of axial strip-seam-shaped through grooves with mutually reversed openings are evenly distributed on the circumference of a cylinder of the expansion ring at intervals; internal screw threads corresponding to the external screw threads at the central part of the core rod are formed on the inner circle of the tube-shaped body; four axial grooves are formed on the excircle of the locking nut; the inner circle of the expansion ring is sleeved on the excircle of the cone body at the right end of the core rod; the inner end surface of a circular ring disc of the locking nut is attached to the right end surface of the circular ring disc at the left part of the expansion ring; and internal screw threads of the locking nut are sleeved on the external screw threads of the core rod. The inner circle of a motor housing is firmly clamped by the expansion ring, and a step hole in the center of an end cap and a spigot on the other end surface are mounted and clamped at one step, thereby guaranteeing the coaxiality.
Description
Technical field:
The utility model relates to motor tool for processing anchor clamps.
Background technology:
Motor generally is made up of motor casing, two end cap, stator rotor, but motor is also arranged in order to save manufacturing procedure, and being designed to electric machine casing one end has disjunctor cecum lid, and the other end is an overcoat end cover structure form, and especially small machine is in the majority.This electric machine casing adds man-hour, blind lid one end is wanted car system central stepped bore, and the other end wants car to prevent mouth and seam end face, after processing technology is generally clamping engine housing cylindrical car system one end, the reverse clamping car system other end again can't keep the axiality of blind lid end central stepped bore and other end seam.
Summary of the invention:
The purpose of this utility model is to overcome above-mentioned defective, and a kind of blind lid formula electric machine casing clamp for machining is provided.
Scheme of the present utility model is: anchor clamps are made up of plug, locking nut, piston ring, and the plug left part is the cone corresponding to lathe spindle end internal taper hole, and the middle part is for being provided with externally threaded cylinder, and the cylinder external diameter is greater than the big footpath of cone; Right part is the cone of path towards the right side, at the bottom of the cone footpath less than the mandrel outer diameter of thread, the cone right side tubular body that extends, plug is provided with the center through hole with the tubular body internal diameter size; The piston ring cylindrical is cylindrical, circle ring disk of its left part cylindrical radial extension, this circle ring disk external diameter is less than the mandrel outer diameter of thread, circle is the conical bore corresponding to plug right part cone in the piston ring, the reverse each other axial bars seam shape groove of uniform several openings of ring weekly interval on the piston ring cylinder, the bottom land of groove is the breach circular hole; Locking nut is to prolong the circle ring disk conjoined structure in the left part tubular body right part, and circle is provided with corresponding to the externally threaded internal thread in plug middle part in the tubular body, and circular diameter is greater than piston ring left part cone external diameter in the circle ring disk, and the locking nut cylindrical is provided with four axial notches; Circle is linked on the plug right-hand member cone cylindrical in the piston ring, and locking nut circle ring disk inner face is fitted on the piston ring left part circle ring disk right side, and the locking nut internal thread is linked on the mandrel outer screw thread.
Advantage of the present utility model is: the electric machine casing that has the disjunctor end cap is interior round by the piston ring fastening clamp, end cap central stepped bore and the disposable clamping of other end seam, and car system guarantees axiality.And the smear metal of car system central stepped bore is eliminated at any time.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the piston ring structural representation.
The specific embodiment:
Structure of the present utility model is characterized in that: anchor clamps are made up of plug 1, locking nut 2, piston ring 3, and plug 1 left part is the cone corresponding to lathe spindle end internal taper hole, and the middle part is for being provided with externally threaded cylinder, and the cylinder external diameter is greater than the big footpath of cone; Right part is the cone of path towards the right side, at the bottom of the cone footpath less than plug 1 external thread diameter, the cone right side tubular body that extends, plug 1 is provided with the center through hole with the tubular body internal diameter size; Piston ring 3 cylindricals are cylindrical, circle ring disk of its left part cylindrical radial extension, this circle ring disk external diameter is less than plug 1 external thread diameter, circle is the conical bore corresponding to plug 1 right part cone in the piston ring 3, the reverse each other axial bars seam shape groove of uniform several openings of ring weekly interval on piston ring 3 cylinders, the bottom land of groove is the breach circular hole; Locking nut 2 prolongs the circle ring disk conjoined structure in the left part tubular body right part, circle is provided with corresponding to the externally threaded internal thread in plug 1 middle part in the tubular body, circular diameter is greater than piston ring 3 left part cone external diameters in the circle ring disk, and locking nut 2 cylindricals are provided with four axial notches; Circle is linked on the plug 1 right-hand member cone cylindrical in the piston ring 3, and locking nut 2 circle ring disk inner faces are fitted on the piston ring 3 left part circle ring disk right sides, and locking nut 2 internal threads are linked on plug 1 external screw thread.
When processing housing or being inserted in the housing clamping of stator, plug 1 left part is inserted in the corresponding taper hole of lathe, with the workpiece inner hole sleeve on piston ring 3, cecum lid inwall withstands on the plug 1 right-hand member tubular body right side, 3 expansions of rotational lock nut 2 piston rings clamp housing endoporus or stator inner hole, then lathe tool stretches into stepped hole in the cecum lid medium pore car system bearing chamber, car system is finished stepped hole, car system engine housing other end seam and seam end face, before unclamping frock, center through hole by the machine tool chief axis centre bore is communicated with plug 1 blows off the aluminium bits with compressed air.The axiality of double-ended vehicle system and the perpendicularity of seam end face have been guaranteed.Rational in infrastructure, the work efficiency height.
