Abstract
The utility model provides a double end main spindle box of a built-in main spindle generator. The double end main spindle box of the built-in main spindle generator is composed of a main spindle, a main spindle motor, a box body, bearings, and flanges. The main spindle is a hollow spindle. The middle of the outer circle of the main spindle is provided with a motor rotor. The left end of the main spindle is provided with double rows of bearings, bearing seats, and a left main spindle flange. The bearing seats are fixedly connected on the left end surface of the box body. The right end of the main spindle is provided with double rows of bearings, a spindle sleeve, a pressing sleeve flange, and a right main spindle flange. The pressing sleeve flange is fixedly connected on the right end surface of the box body. A motor stator is arranged inside the box body. The cooling liquid of a refrigerator passes through the inner cavity of the double end main spindle box to carry out cooling to a motor stator. A tooth signaler and an encoder are provided between the pressing sleeve flange and the right main spindle flange and on the right end of the main spindle. The utility model has simple structure, good rigidity, high rotating precision, and stable operation. Two ends of the double end main spindle box of the built-in main spindle generator can be provided with clamping disks to carry out simultaneously installing and clamping the parts of a long shaft class, and simultaneously processing the parts of the long shaft class.
Description
Technical field
The utility model relates to a kind of lathe headstock, especially a kind of main spindle box of built-in spindle motor.
Background technology
Lathe headstock is one of most important parts in the stock-removing machine.The driving rigidity of main shaft, running accuracy, smoothness of operation etc. are the topmost technical indicators that directly influences cut precision and efficient.The turning processing machine tool overwhelming majority of prior art adopts motor-mechanical transmission mechanism to form main spindle box, the driving of main shaft, speed change are to be realized by driving-belt and gear, therefore, main spindle box complex structure, volume are greatly, accuracy of manufacture requirement is high, the high speed rotating vibration is big, stationarity is poor, power of motor loses greatly.If make the double-output shaft active axle box, mechanism is more complicated, keeps in repair, installs more difficult.
Summary of the invention
The utility model purpose is the defective that will overcome existing main spindle box, satisfy of the requirement of step axle double end processing numerical control transfer matic, but provide a kind of simple in structure, good rigidly, precision height, running steadily to be installed, to process simultaneously the double end main spindle box of the built-in spindle motor of longaxones parts synchronously in two ends main spindle box.
The utility model is for realizing its purpose, and the technology implementation scheme of employing is: a kind of double end main spindle box of built-in spindle motor, form by main shaft, spindle motor, casing, bearing, flange.Main shaft is a hollow shaft, is provided with rotor in the middle of the main shaft cylindrical, and left end is provided with double-row bearing, bearing pedestal, left spindle flange, and bearing pedestal is fixedly connected on the casing left side; The main shaft right-hand member is provided with double-row bearing, axle sleeve, gland flange, right spindle flange, and the gland flange is fixedly connected on the casing right side, is provided with motor stator in the casing, and motor stator is circumscribed with cooling water pipe.The main shaft right-hand member also is provided with teeth signalling generator and encoder between gland flange and the right spindle flange.Left side spindle flange is connected with main shaft with the hot cover process method with right spindle flange.Bearing is a precision angular contact ball bearing in groups, and " back-to-back " arranges.
The utility model is owing to adopted above-mentioned technical scheme, and therefore the beneficial effect that has is: but main spindle box is simple in structure, good rigidly, running accuracy height, running steadily two ends be installed dish be installed synchronously longaxones parts, process longaxones parts simultaneously.
Description of drawings
Accompanying drawing 1 is a structure installation diagram of the present utility model.
Embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Shown in Figure 1, the double end main spindle box of built-in spindle motor is made up of main shaft 1, spindle motor, casing 2, bearing 4, flange 5, flange 10 etc.Main shaft 1 adopts hollow shaft, main shaft 1 cylindrical center fixed is with rotor 3, angular contact ball bearing 4, bearing pedestal 6, left spindle flange 5 that " back-to-back " installs are housed in groups on the main shaft 1 left end step axle, bearing pedestal 6 is screwed and is connected on casing 2 left sides, and left spindle flange 5 is fixedly connected on main shaft 1 left end shaft by the hot jacket method; Angular contact ball bearing 4, axle sleeve 8, gland flange 7, teeth signalling generator 9, encoder 11, right spindle flange 10 that " back-to-back " installs are housed in groups on the main shaft 1 right-hand member step axle, gland flange 7 is screwed and is connected on casing 2 right sides, right spindle flange 10 is fixedly connected on the main shaft 1 right-hand member axle by the hot jacket method, and teeth signalling generator 9 is connected on right spindle flange 10 inner faces.With rotor 3 corresponding sections motor stator 12 is housed in the casing 2, motor stator 12 is circumscribed with cooling water pipe 13, on the cylindrical of two ends sealing ring is housed.
