Abstract
The invention discloses a coaxiality tool for stators and casings of efficient motors. The coaxiality tool is applicable to machining the coaxiality of the casings and the stators of the efficient motors. The tool comprises a spindle, an outer pushing taper sleeve, an expanding mandrel, a compression nut, a positioning pin and a gasket. The tool and the process guarantee effective machining for coaxiality of inner circles of the stators and seams of the casings of the efficient motor. The coaxiality tool is simple in structure, low in cost and simple and easy to install, and machining precision and work efficiency are improved.
Description
Technical field
[0001] the present invention relates to a kind of high efficiency motor stator cage axiality frock, is casing and stator axiality tool structure for processing and the production technology field that belongs to high efficiency motor.
Background technology
[0002] existing high efficiency motor casing adopts materials such as aluminium alloy, almag, steel plate reel to process mostly, but the casing that these aluminium alloys, almag, steel plate cylinder material are constituted be easy in the manufacturing process distortion so that after motor stator is pressed into casing; Motor case seam and the different axle center of the interior circle of stator; Cause motor stator and rotor coaxial degree deviation, motor gas-gap is uneven, and motor oscillating strengthens; Mechanicalness noise appears, consequences such as inefficiency.
Stator itself has the coaxiality deviation of the inside and outside circle margin of tolerance, even normally be pressed into casing axiality problem is in various degree arranged also, thus to motor gas-gap to do big, efficiency of motor and power factor decline like this.
Summary of the invention
The objective of the invention is to solve the weak point in the above-mentioned existing production technology and provide a kind of simple in structure, cost is low, installs simple and easyly, improves the high efficiency motor stator cage axiality frock of machining accuracy and operating efficiency.Mainly include: a kind of high efficiency motor stator cage axiality frock; Include main shaft (1), extrapolation tapered sleeve (2), the carcass (3) that expands, clamp nut (5), alignment pin (4) formation; It is characterized in that main shaft (1) is connected with extrapolation tapered sleeve (2); The carcass (3) that expands is connected with extrapolation tapered sleeve tapering (21) with spindle taper (12) and locatees through alignment pin (4); The extrapolation same pad of tapered sleeve (2) (6) compresses with clamp nut (5), and clamp nut (5) matches to merge with main shaft bolt (15) and can regulate extrapolation tapered sleeve (2) moving axially on main shaft (1).
1. according to the described a kind of high efficiency motor stator cage axiality frock of claim 1, its characteristic has main shaft (1), extrapolation tapered sleeve (2), carcass (3) concentric that expands, and identical taper fit is arranged.
2. according to the described a kind of high efficiency motor stator cage axiality frock of claim 1, it is that resilient metal constitutes and the integral body of 6-8 bisector cutting groove (31) that characteristic has bloated carcass (3), has to swell and dwindle the return function.

The specific embodiment
Combine accompanying drawing, the specific embodiment of the invention is detailed: the purpose of invention is to solve the weak point in the above-mentioned existing production technology at present, improves the high efficiency motor stator cage axiality frock of machining accuracy and operating efficiency.Mainly include: a kind of high efficiency motor stator cage axiality frock includes:
Main shaft as shown in Figure 1 (1), extrapolation tapered sleeve (2), the carcass (3) that expands, clamp nut (5), alignment pin (4) (14) constitute, and it is characterized in that main shaft (1) slidably is connected with keyway (22) through alignment pin (14) with extrapolation tapered sleeve (2); The carcass tapering (32) that expands is connected with extrapolation tapered sleeve tapering (21) with spindle taper (12) and locatees in order to avoid cause rotation through alignment pin (4); The extrapolation same pad of tapered sleeve (2) (6) compresses with clamp nut (5), and clamp nut (5) matches to merge with main shaft bolt (15) and can regulate extrapolation tapered sleeve (2) moving axially on main shaft (1).
It is that resilient metal constitutes and the integral body of 6-8 bisector cutting groove (31) that a kind of high efficiency motor stator cage axiality frock as shown in Figure 3, its characteristic have bloated carcass (3), has to swell and dwindle the return function.
As Fig. 1 and embodiment illustrated in fig. 5 in main shaft (1), extrapolation tapered sleeve (2) are arranged, carcass (3) concentric expands; And identical taper fit is arranged; Extrapolation tapered sleeve (2) is when main shaft root direction moves; The carcass tapering (32) that expands outwards opens bloated carcass (3) through spindle taper (12) and extrapolation tapered sleeve tapering (21) thrust; With circle (81) and stretching stator (8) in the tight clamping motor stator, when main shaft root tapering (11) just cooperates with lathe when rotating can disposable processing casing (7) two ends seam (71) (72), assurance motor stator interior round (81); With motor case seam axiality, circle disengaging in inside contraction of bloated carcass (3) and the motor stator (8) when the tapered sleeve (2) of extrapolating moves outside axle.
The present invention provides a kind of can significantly reduce motor gas-gap length, improves high efficiency motor efficient and power factor, improves machining accuracy and operating efficiency, and technology is simple, and cost is low, and installation and removal are easy.
Claims (3)
1. high efficiency motor stator cage axiality frock; Include main shaft, extrapolation tapered sleeve, the carcass that expands, clamp nut, alignment pin, pad formation; It is characterized in that main shaft is connected with the extrapolation tapered sleeve; The carcass that expands is connected with the extrapolation tapered sleeve with spindle taper and through the alignment pin location, the extrapolation tapered sleeve compresses through pad and clamp nut, and clamp nut and main shaft bolt match to merge and can regulate extrapolation tapered sleeve moving axially on main shaft.
2. according to the described a kind of high efficiency motor stator cage axiality frock of claim 1, its characteristic has main shaft, extrapolation tapered sleeve, the carcass concentric that expands, and identical taper fit is arranged.
