Abstract

An apparatus for automatically press-fitting a turntable has a turntable driving motor which is attachably/detachably installed to/from a driving motor fixing part for inserting a rotating shaft of the driving motor into a turntable assembly with significantly high precision to minimize eccentric error. Here, a first press-fitting part pressively fixes the driving motor to the driving motor fixing part, and a second press-fitting part descends the driving motor fixing part press-fitted with the driving motor in a motor shaft direction. The center of a turntable assembly fixing part is arranged at an extending line of driving motor shaft to allow a rotating shaft of the turntable assembly to be exactly coaxial with the driving motor.

Dependent claims

An apparatus for automatically press-fitting a turntable comprising:

a driving motor fixing part for being installed with an attachable driving motor;
a first press-fitting part for pressively-fixing said driving motor into said driving motor fixing part;
a second press-fitting part for moving said driving motor fixing part press-fitted with said driving motor in the direction of a motor shaft;
and
a turntable assembly fixing part for being installed with an attachable turntable assembly, the turntable assembly fixing part having a central axis arranged at an extending line of a shaft of the driving motor to permit a rotating shaft of said turntable assembly to be exactly coaxial with said driving motor when said turntable assembly is installed at the turntable assembly fixing part,
said turntable assembly fixing part having
an annular projection formed coaxially with and on an upper portion of the turntable assembly fixing part, said annular projection being inserted into a groove of round shape formed on a supporting shaft member of said turntable assembly,
a guiding slot for being penetrated up and down along the central axis of the turntable assembly fixing part, a space formed under the guiding slot having a diameter greater than that of the guiding slot, and
a guide pin installed in the guiding slot and the space of the turntable assembly fixing part, the guide pin being formed to have a lower end installed to be in contact with an elastic spring and an upper end penetrating through the guiding slot and protruding over the annular projection, and the guiding slot for allowing a central axis of the guide pin to be exactly coaxial with the motor shaft of the driving motor.

An apparatus for automatically press-fitting a turntable comprising:

a driving motor fixing part for being installed with an attachable driving motor, said driving motor fixing part being installed with a photosensitive switch at a predetermined position of an internal space in which the driving motor is to be disposed for sensing the mounting of said driving motor into said driving motor fixing part to thereby drive a first
a first press-fitting part for pressively-fixing said driving motor into said driving motor fixing part,
a second press-fitting part for moving said driving motor fixing part press-fitted with said driving motor in the direction of a motor shaft;
and
a turntable assembly fixing part for being installed with an attachable turntable assembly, the turntable assembly fixing part having a central axis arranged at an extending line of a shaft of the driving motor to permit a rotating shaft of the turntable assembly to be exactly coaxial with the driving motor when the turntable assembly is installed at the turntable assembly fixing part.

a turntable assembly fixing part for being installed with an attachable turntable assembly, the turntable assembly fixing part having a central axis arranged at an extending line of a shaft of the driving motor to permit a rotating shaft of the turntable assembly to be exactly coaxial with the driving motor when the turntable assembly is installed at the turntable assembly fixing part;
and
a photosensitive sensor for sensing an inclined range of said driving motor mounted to said driving motor fixing part, an A/D converter for converting an analog signal with respect to the inclination sensed in said photosensitive sensor into a digital signal, a microprocessor for comparing the inclination value displayed as said digital signal supplied from said A/D converter with a preset allowable inclination value, and a digital display board for externally displaying the numerical value determined in said microprocessor, so that said driving motor is more precisely mounted into said driving motor fixing part.
