Abstract

The present invention relates to a coupling measure of a safety seat for infants to be mounted to a vehicle seat for safety of infants during the operation of a vehicle. And, more specifically, the present invention relates to the coupling measure of a safety seat for infants which is mounted to a vehicle seat for the safety of infants and is configured to mutually fixate a belt of a safety seat which restricts the body movement of infants. The coupling measure comprises: a coupling device which forms securing devices protruded on both sides and lower side, wherein the securing devices form a securing groove; a first buckle to which a first belt to restrain one shoulder and one side of the waist of an infant is fixated, and a coupling with securing devices formed in a side among securing devices formed at both sides of the coupling device is achieved; a second buckle to which a second belt to restrain the opposite shoulder and the opposite side of the waist of an infant is fixated, and a coupling with securing devices formed in an opposite side of the coupling of the coupling device with the first buckle is achieved; and a third buckle to which a third belt to restrain the crotch of an infant is fixated, and a coupling with securing devices protruded in a lower side of the coupling device is achieved. The coupling measure separately restrains each portion of an infant by executing coupling actions of a first, a second and a third securing devices which are formed in three directions of a coupling device, thereby maintaining safety of an infant even if an impact is applied to a vehicle through the separate restraint of each portion of an infant.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic machining apparatus for a motor for chamfering both sides of a magnet used in a motor, To a magnet processing apparatus for a motor.

Generally, a motor is a device that converts electrical energy into mechanical work by using the force that a current receives in a magnetic field. It is used as a driving source in various household appliances and industrial devices. The motor is supplied with DC or AC current As shown in Fig.

The motor is largely divided into a stator side and a rotor side, and a space for installing a rotor is formed at the center of the stator so that the rotor is installed inside the stator. Further, the inner surface of the stator is provided with a tooth portion extending radially from the center, and a slot through which the coil is wound is formed between adjacent tooth portions.

The rotor is spaced apart from the tooth portion of the stator by a predetermined distance. The rotor is composed of a rotor core which is located at the center thereof and to which a rotor is mounted and magnets arranged so as to have different poles in the circumferential direction on the outer circumferential surface of the rotor core

The magnets are formed in an arcuate shape so as to face each other at predetermined intervals on the inner circumferential surface of the motor housing. However, in the process of inserting and fixing the magnet into the housing, the corner of the magnet sometimes collides with the housing or a large number of parts and is often broken.

Therefore, in order to prevent the damage of the magnet, it is necessary to apply edge machining to the edges of both sides of the magnet. In order to do this, the work force is directly processed by the machining machine, The defect rate depends on the degree of the defect, and there is a disadvantage that the transfer to the post-process is not easy.
