Abstract
The utility model discloses an automatic locking device of car processing motor shaft belongs to motor production field, including the device base, device base center is equipped with the motor shaft hole, is equipped with the positioning screw of symmetry about the motor shaft hole, is connected with the balancing weight on the positioning screw, and device base one side is equipped with the even three axle connecting hole in interval. The utility model discloses when upper and lower work piece, do not need the tight, the process of relaxing of clamp of manual operation motor shaft spare part, productivity gain greatly.
Description
Technical Field
The utility model provides an automatic locking device of car processing motor shaft belongs to the motor production field.
Background
In the production process of the motor, the turning of the motor rotating shaft is repeated in multiple batches. In the turning process of the rotating shaft, the clamping and loosening processes of the rotating shaft are continuously repeated, the clamping and loosening processes of the rotating shaft need to be manually completed, and the efficiency is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a can overcome the automatic locking device of car processing motor shaft of above-mentioned defect, when it can upper and lower work piece, do not need the tight, the process of relaxing of clamp of manual operation motor shaft spare part.
A car processing motor shaft's automatic locking device, including the device base, device base center is equipped with the motor shaft hole, is equipped with the positioning screw of symmetry about the motor shaft hole, is connected with the balancing weight on the positioning screw, device base one side is equipped with the even three axle connecting hole in interval.
The balancing weight presses the motor rotating shaft under the action of the rotating centrifugal force of the lathe spindle and drives the motor rotating shaft to rotate. When the lathe spindle stops rotating, the rotating centrifugal force disappears, and the balancing weight is automatically released.
Preferably, the balancing weight is S-shaped, and the bending radian of the S-shaped balancing weight is matched with the rotating shaft of the motor.
The S-shaped balancing weight can increase the force for crimping the rotating shaft under the action of centrifugal force.
Preferably, the balancing weight is provided with an arc-shaped pressing tooth, and the arc-shaped pressing tooth is clamped with the motor rotating shaft.
The arc-shaped pressing teeth increase the friction force and prevent the slipping and deviation in the rotating process.
Has the advantages that:
the utility model discloses the balancing weight pushes down motor shaft under the effect of the rotatory centrifugal force of lathe spindle to it is rotatory to drive the motor shaft machined part. When the lathe spindle stops rotating, the rotating centrifugal force disappears, and the balancing weight is automatically released. When the workpiece is loaded and unloaded, the clamping and loosening processes of the motor rotating shaft parts do not need to be manually operated.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
in the figure: 1. a shaft connecting hole; 2. a base; 3. a balancing weight; 4. and (5) positioning the screw rod.
Detailed Description
Example 1
Including device base 2, device base 2 center is equipped with motor pivot hole, and motor pivot hole is equipped with symmetrical positioning screw 4 from top to bottom, is connected with balancing weight 3 on the positioning screw 4, is equipped with three axle connecting hole 1 at even interval on the device base 2.
The balancing weight 3 is S-shaped, and the bending radian of the S-shaped balancing weight is matched with the rotating shaft of the motor.
Arc-shaped pressing teeth are arranged on the balancing weight 3 and are clamped with the motor rotating shaft.
During actual work, a thimble rod is arranged on a lathe spindle, and the automatic locking device is tightly connected with a chuck position on the lathe spindle through three shaft connecting holes 1 on a base 2 by a screw rod. And taking a rotating shaft workpiece, penetrating through the two balancing weights 3 of the automatic locking device, ejecting a main shaft ejector pin rod into a rotating shaft hole of a motor of the rotating shaft workpiece, and ejecting a lathe tailstock ejector pin rod into a center hole at the other end of the rotating shaft workpiece. The lathe spindle is started to rotate, and the automatic locking device rotates along with the spindle. Two balancing weights 3 of the locking device expand outwards along the positioning screw rod 4 under the action of the rotating centrifugal force of the lathe spindle, and the arc-shaped pressing teeth of the balancing weights 3 press the motor rotating shaft and drive the motor rotating shaft to rotate. The main shaft stops rotating, the rotating centrifugal force of the balancing weight of the locking device disappears, and the pressure of the arc-shaped pressing teeth of the balancing weight on the motor rotating shaft workpiece disappears. And (5) loosening the ejector pin rod of the tailstock of the lathe to directly take down the workpiece.
