A kind of processing unit (plant) of motor stator for outer rotator

Technical field

The utility model relates to the external rotor electric machine processing technique field, is specifically related to a kind of processing unit (plant) of motor stator for outer rotator.

Background technology

In the prior art, the processing of motor stator for outer rotator is carried out at centre numerically controlled lathe.General process is: (1) processes the size (so that end cap can be pressed into the stator armature of motor stator for outer rotator) of Φ D and the bearing chamber of Φ B position in the position that centre numerically controlled lathe is clamped Φ F on the end cap; (2) folder that changes the outfit, the position of clamping Φ D on the end cap processes the bearing chamber of Φ A position; (3) end cap is pressed into the stator armature of motor stator for outer rotator.There is following defective in the processing method of this motor stator for outer rotator: at first this processing method need to change the outfit and press from both sides processing, because error is too large behind the folder that changes the outfit, the end cap after the processing can't guarantee the axiality of two bearing chambers (Φ A position and Φ B position) substantially; Secondly prove through production practices, be pressed into again the stator armature of motor stator for outer rotator after two bearing chamber processing of end cap, cause the size of end cap to change, thereby do not meet production requirement.

The utility model content

Technical problem to be solved in the utility model provides a kind of processing unit (plant) of motor stator for outer rotator, utilizes this processing unit (plant) can process simultaneously two bearing chambers of motor stator for outer rotator, thereby has effectively guaranteed the axiality of two bearing chambers.

The technical scheme that the utility model adopts is: a kind of processing unit (plant) of motor stator for outer rotator, this processing unit (plant) is a kind of double end turning lathe: comprise that lathe bed, level are fixed in the straight guide rail of lathe bed, are fixed in the anchor clamps of lathe bed, the first knife rest that lays respectively at the anchor clamps both sides and the second knife rest.Be connected with hydraulic chuck by rolling bearing on the described anchor clamps, the stator core cylindrical tight fit of hydraulic chuck inner chamber and motor stator for outer rotator when described hydraulic chuck is wedge structure and voussoir clamping, namely when Hydraulic Station during to hydraulic pressure chuck right side oil pocket fuel feeding, voussoir moves to left, and the hydraulic chuck inner chamber diminishes, and the stator core cylindrical that clamps motor stator for outer rotator is Φ C position, when Hydraulic Station during to chuck left side oil pocket fuel feeding, voussoir moves to right, and it is large that the hydraulic chuck inner chamber becomes, and decontrols motor stator for outer rotator.Described hydraulic chuck is connected with the chuck drive motors by belt and can drives motor stator for outer rotator and be rotated take cavity as axle.Have oat tail groove structure on the described guide rail, described the first knife rest, the second knife rest are connected with guide rail by oat tail groove structure, described the first knife rest, the second knife rest respectively are subjected to a servomotor to become the horizontal slip kinematic pair by reduction box control along guide rail, can be simultaneously along guide rail to the anchor clamps feeding.Cavity, the second knife rest in described the first knife rest, the motor stator for outer rotator are on the same level line, like this when the first knife rest, the second knife rest during simultaneously along guide rail to the anchor clamps feeding, the first knife rest, the second knife rest can be just is that Φ A position and Φ B position process simultaneously to two bearing chambers of motor stator for outer rotator.

Utilize the processing method of the motor stator for outer rotator that the processing unit (plant) of above-mentioned motor stator for outer rotator carries out, may further comprise the steps:

(1) revise the size of Φ D position on the end cap, end cap be pressed into the stator armature of motor stator for outer rotator, make end cap just with the stator armature tight fit;

(2) motor stator for outer rotator is packed in the anchor clamps, the stator core cylindrical that clamps motor stator for outer rotator with hydraulic chuck is Φ C position;

(3) drive motors of startup hydraulic chuck makes hydraulic chuck drive motor stator for outer rotator and rotates together;

(4) starting the servomotor of the first knife rest, the second knife rest, make the first knife rest, the second knife rest simultaneously along guide rail to the anchor clamps feeding, is simultaneously disposable machining of Φ A position and Φ B position with two bearing chambers of motor stator for outer rotator.

Compared with prior art, the utlity model has following remarkable advantage and beneficial effect: the homemade processing unit (plant) of the utility model---double end turning lathe is realized the processing to motor stator for outer rotator, owing to be that Φ C position is as machining benchmark with the stator core cylindrical, consistent with design basis in process, there is not accumulated error, two bearing chambers (Φ A position and Φ B position) are disposable machining simultaneously, can fully guarantee the axiality of two bearing chambers, greatly improved machining accuracy, to satisfy effectively production requirement.
