The tool magazine is used to store tools, and it is one of the main components in the automatic tool changer.
According to the number of tools placed in the tool stock and the way of taking the tools, the tool magazine can be designed into different types.
Figure 7.1 shows several common tool magazine forms.
(1) Linear tool magazine. As shown in Figure 7.1(a), the tools are arranged in a straight line in the tool magazine, the structure is simple, and the number of tools stored is limited (usually 8-12), which is rarely used.
(2) Disc tool magazine. As shown in Figure 7.1(b)-(g), the number of stored knives is as small as 6-8 pieces, and as many as 50-60 pieces, and there are various forms.
The tool magazine shown in Figure 7.1(b), the tools are arranged radially, occupying a large space, and are generally placed on the upper end of the machine tool column.
The tool magazine shown in Figure 7.1(c), the tools are arranged in the axial direction, often placed on the side of the spindle,
The axis line of the tool magazine can be placed vertically or horizontally, which is often used.
The tool magazine shown in Figure 7.1(d), the tools are arranged in an umbrella shape, and they are mostly placed diagonally on the upper end of the column.
In order to further expand the amount of tool storage, some machine tools use a disc tool magazine with multi-circle distributed tools (Figure 7.1(e)),
Multi-layer disc tool magazine (Figure 7.1(f)) and multi-row disc tool magazine (Figure 7.1(g)). The multi-row disc tool magazine has 4 knives in each row, which can be replaced in the entire row.
The last three types of tool magazines are used less frequently.
(3) Chain tool magazine. Chain tool magazine is a more commonly used form (Figure 7.1 (h), (i)),
Commonly used are single-row chain tool magazines (Figure 7.1(h)) and chain tool magazines with extended chains (Figure 7.1(i)).
(4) Other tool magazines. The lattice box type tool magazine, as shown in Figure 7.1(j), k, has a large tool magazine capacity.
