Abstract
A machine tool is provided with a chain-type bit-storing apparatus which includes a frame, two sprockets, a chain and a pivoting unit. The frame includes a cutout. The sprockets are placed in the frame. The chain is driven by the sprockets. The chain includes links each including a socket for containing a bit, two plates for supporting the socket, first and second blocks placed between the plates, first and second bearing units for rotationally supporting the first and second blocks on the plates, and a connecting unit for pivotally connecting the first block thereof to the second block of an adjacent link. The pivoting unit is used to pivot the socket of a selected one of the links to move an open end of the socket out of the frame through the cutout.
Claims20
A chain-type bit-storing apparatus including:
- a frame including a cutout;
- two sprockets placed in the frame;
- a chain driven by the sprockets and formed with links each including a socket for containing a bit, two plates for supporting the socket, two blocks placed between the plates, two bearing units for rotationally supporting the blocks on the plates, and a connecting unit for pivotally connecting one of the blocks thereof to one of the blocks of an adjacent link;
- and
- a pivoting unit for pivoting the socket of a selected one of the links to move an open end of the socket out of the frame through the cutout.
A chain-type bit-storing apparatus including:
- a frame including a cutout;
- two sprockets placed in the frame;
- a chain driven by the sprockets, wherein the chain includes links connected to one another so that the chain becomes a loop, wherein each of the links can be pivoted about an axis in a plane defined by the loop independent of the other links;
- and
- a pivoting unit for pivoting the socket of a selected one of the links to move an open end of the socket out of the frame through the cutout, wherein the pivoting unit includes a driving element connected to the frame, a pivoting element connected to the driving element and used to receive the selected link, and a guiding element for pivotally supporting the pivoting element in the frame.
The chain-type bit-storing apparatus according to claim 18, wherein the pivoting element includes at least one arched flange, wherein the guiding element includes at least one roller in contact with a side of the arched flange and at least two more rollers in contact with an opposite side of the arched flange.
