Abstract: An upright chuck assembly includes a base having two elongate notches respectively defined in two sides thereof. A rotary device is connected to the base and includes a horizontal gear set and a vertical gear set which are engaged with the horizontal gear set in the body of the rotary device. An insertion extends from the horizontal gear set and is inserted into one of the adjustable members. The vertical gear set has a connection portion on the top thereof, and a T-wrench is mounted to the connection portion. The rotary device is cooperated with a vertical machine center.

Abstract: A multiple-function clamping device includes a rotary base having an annular groove in the top thereof and scale marks are marked along in inclined surface of the rotary base. A positioning unit includes a first positioning member and a second positioning member. The positioning unit is located in the annular groove to form a linear slot. The first positioning member has a first alignment line and multiple linear marks. A vise has two side slots defined in two sides thereof so as to form an engaging portion which is engaged with the linear slot between the first and second positioning members. The vise further has a second alignment line located corresponding to the linear scale marks of the first positioning member. The vise can be moved linearly or rotatably so as to meet different requirements when machining an object.

Abstract: A clamping device for clamping different sizes of cylindrical objects includes a body having a path defined centrally therethrough. The body has a polygonal section which has multiple corners at equal intervals. A clamping portion having outer threads is connected to one end of the polygonal section and a locking collar is threadedly connected to the clamping portion. The clamping portion clamps an object. The body has a room defined therein and the room has a tapered inside so as to accommodate a clamping sleeve which has a clamping hole and a tapered outside which is engaged with the tapered inside of the room. The clamping collar controls the size of the clamping hole of the clamping sleeve to proceed vertical or horizontal machining. The clamping sleeve releases the object by loosing the locking collar.
