DESCRIPTION EASILY-LIMITED COMMUTATOR ASSEMBLY DEVICE Technical Field of the Invention
The present invention relates to an easily-limited commutator assembly device.
Background of the Invention A rotor is an important component of a motor. The transformation of polarity of the rotor of the motor depends upon the change in the direction of electricity supply. A commutator is provided in a portion of a rotor shaft close to a rotor coil. Since the existing commutators are mostly in interference fit with the rotor shaft, the commutator may be broken due to over-pressure or the commutator may be not properly assembled due to under-pressure when fitting the commutator and the rotor shaft by the operators.
Summary of the Invention
An objective of the present invention is to provide an easily-limited commutator assembly device.
In order to achieve this objective, the present invention adopts a technical solution as follows: a commutator assembly device of the present invention is provided, including a pedestal, a driving device, a rotor carrier for holding a rotor and a commutator carrier for holding a commutator; a guide rail is provided on the pedestal, a rotor carrier soleplate is provided on a lower side of the rotor carrier, and the rotor carrier is located at one end of the rotor carrier soleplate and a push plate is provided at the other end thereof; a push rod, which is configured to come into contact with a rotor shaft of the rotor and arranged transversely, is fixed on the push plate, and the rotor carrier soleplate is interlocked with the driving device; a stopper is matched to the commutator 1 2017100775 16 Jun2017 carrier, the commutator carrier is located between the stopper and the rotor carrier, and the rotor carrier is located between the commutator carrier and the push plate; the driving device moves to drive the rotor carrier to move along the guide rail, and a pocket hole, through which the rotor shaft passes, is formed on the stopper;a commutator holding groove for holding a commutator is formed on the commutator carrier, a notch for pocketing a hook of the commutator is formed on one side of the commutator carrier close to the rotor carrier and communicated with the commutator holding groove, and the commutator holding groove is located between the notch and the stopper and provided with a second cambered surface adapted to the surface of the commutator. This arrangement is provided for the radial limitation of the commutator so that, during the placement of the commutator, a peripheral surface of the commutator comes into contact with the second cambered surface the hook of the commutator is located in the notch, and one end of the commutator far away from the rotor carrier is resisted against the stopper.
Preferably, two commutator limiting bulges, which are vertically arranged, are formed in the middle of the notch, and the distance between the two commutator limiting bulges is adapted to the width of the hook of the commutator; and when the commutator is held in the commutator holding groove, one hook of the commutator is located between the two commutator limiting bulges. This arrangement is provided for the radial limitation of the commutator so as to prevent the commutator from overturning due to an external force (a force exerted to the commutator when the push rod pushes the rotor shaft or a force exerted by the operator when accidentally touching the commutator).
The present invention provides a commutator assembly device which is easy to assemble a commutator and a rotor and capable of improving the assembly efficiency and reducing the defective rate.

The technical solution in the embodiments of the present invention will be clearly and completely described as below with reference to the accompanying drawings in the embodiments of the present invention.
As shown in Fig. 1, an embodiment of the present invention provides a commutator assembly device, including a pedestal 1, a driving device, a rotor carrier 2 for holding a rotor and a commutator carrier 3 for holding a commutator; a guide rail is provided on the pedestal 1, a rotor carrier soleplate 4 is provided on a lower side of the rotor carrier 2, and the rotor carrier 2 is located at a left end of the rotor carrier soleplate 4 and a push plate 5 is provided at a right end thereof; a push rod 10, which is configured to come into contact with a rotor shaft of the rotor and arranged transversely, is fixed on the push plate 5, and the rotor carrier soleplate 4 is interlocked with the driving device; a stopper 6 is matched to the commutator carrier 3, the commutator carrier 3 is located between the stopper 6 and the rotor carrier 2, and the rotor carrier 2 is located between the commutator carrier 3 and the push plate 5; and the driving device moves to drive the rotor carrier 2 to move along the guide rail, and a pocket hole 7, through which the rotor shaft passes, is formed on the stopper 6. The driving device is an air cylinder 8 whose output end is fixed to the push plate 5, and the air cylinder is located on a right side of the push plate 5. A throttle valve 13 and a foot switch which is configured to control the motion of an output shaft of the air cylinder are matched to the air cylinder 8. When the 3 2017100775 16 Jun2017 foot switch is triggered, the output shaft completes a reciprocating motion. The guide rail is a linear guide rail 9, and the rotor carrier soleplate 4 is fixed on an upper side of a slider 14 of the linear guide rail 9.
As shown in Fig. 1 and Fig. 2, a rotor holding groove 21 for holding a rotor is formed on the rotor carrier 2 and provided with a first cambered surface 22 adapted to a surface of the rotor, and several first rotor limiting bulges 23 whose width is adapted to that of the rotor holding groove are formed on the first cambered surface 22. A second rotor limiting bulge 24, which is vertically arranged, is formed on an upper side of the first rotor limiting bulge 23 in the middle of the rotor holding groove 21 and can be coordinated inside the rotor holding groove.
As shown in Fig. 1, Fig. 3 and Fig. 4, a commutator holding groove 31 for holding a commutator is formed on the commutator carrier 3, a notch 32 for pocketing a hook of the commutator is formed on one side of the commutator carrier 3 close to the rotor carrier 2 and communicated with the commutator holding groove 31, and the commutator holding groove 31 is located between the notch 32 and the stopper 6 and provided with a second cambered surface 33 adapted to the surface of the commutator. Two commutator limiting bulges 34, which are vertically arranged, are formed in the middle of the notch 32, and the distance between the two commutator limiting bulges 34 is adapted to the width of the hook of the commutator.
As shown in Fig. 1, the pocket hole 7 runs through the stopper 6, a nut 15 and a first adjusting screw 11 matched thereto are fixed in the pocket hole 7, and an axis of the first adjusting screw 11 is in the same plane as that of the push rod. A second adjusting screw 12, an axis of which is in the same plane as that of the push rod 10, is provided on a lower side of the commutator carrier 3, and a thread structure adopted to the second adjusting screw 12 is formed on the stopper 6. When the commutator is coordinated with the rotor shaft, the second adjusting screw 12 is resisted against an end face on the left side of the rotor carrier soleplate 4. 4 2017100775 16 Jun2017
When in use, an operator first places the rotor into the rotor holding groove 21 of the rotor carrier 2, with the first rotor limiting bulges 23 and the second rotor limiting bulges 24 being all located in the rotor holding groove, and one end of the rotor shaft far away from the commutator carrier 3 being resisted against the push rod. The commutator is placed into the commutator holding groove 31 of the commutator carrier 3 so as to be resisted against the stopper 6, and a hook of the commutator is located between the two commutator limiting bulges 34.
Then, the operator starts the driving device by stepping on the foot switch of the air cylinder 8, the air cylinder 8 pushes the rotor carrier soleplate 4 and the rotor carrier 2 to move leftward along the linear guide rail 9, and the push rod 10 pushes the rotor to move leftward so as to enable the rotor shaft to pass through the commutator. The commutator is pressed on the rotor shaft by the stopper 6 and the push rod 10. Then, the air cylinder drives the rotor carrier soleplate 4 and the rotor carrier 2 to move rightward along the linear guide rail 9. Now, the operator takes the well-assembled rotor down, to get ready for assembling the next rotor after the rotor carrier soleplate 4 and the rotor carrier 2 are both reset.
The present invention provides a commutator assembly device which is easy to assemble a commutator and a rotor and capable of improving the assembly efficiency and reducing the defective rate. 5
