Problems solved by technology
[0004] However, if the volume of the tool storage compartment is increased, the weight of the cutter head will easily increase as the volume increases, resulting in deformation or tilt of the processing machine equipped with the cutter head due to the excessive weight, which will affect the accuracy of the processing process
[0005] As for increasing the number of clamping arms holding the tool inside the tool storage compartment, since the clamping arms are generally fixed on the periphery of the cutterhead and adjacent to each other, the machining spindle is easily affected by the clamping arms or other clamping arms on the adjacent sides when changing the tool. The interference of the cutting tool leads to difficult alignment or unsmooth installation, and even collisions, which cause the machining spindle to be skewed and deformed, thus affecting the accuracy of the machining process

A cutter changing device of a machine tool is configured on the machine tool and comprises a rail disc provided with a guide groove at the peripheral edge, the part of the guide groove at the upper part of the rail disc being semicircular, the part of the guide groove at the lower part of the rail disc being semielliptical and the two being connected to form the guide path of the guide groove; a cutter disc arranged at one side of the rail disc and capable of rotating relative to the guide groove and the rail disc, support arms being annularly arranged radially at an equal interval at the peripheral edge of the cutter disc; and a plurality of clamping arms pivoted on the support arms, used for clamping cutters and provided with a positioning ball capable of being correspondingly accommodated in the guide groove. When the support arm approaches to the lower part of the rail disc, the clamping arm connected with the support arm can swing outwards to form relatively large spacing between the clamping arm and an adjacent clamping arm, so as to prevent interference or collision of the clamping arms on the two sides when the cutter is mounted, reduce cutter changing error probability and save cutter changing time.
Description
technical field [0001] The invention relates to a tool exchange device for a processing machine; in particular, it refers to a tool exchange device that can increase the number of stored tools without affecting the smoothness and convenience of tool exchange. Background technique [0002] It is generally used in vertical lathes or comprehensive processing machines of turning and milling centers. In order to store heavy-cutting turning tools, general turning tools or light-cutting turning tools of different specifications and uses, a tool storage compartment is usually equipped at the place where the processing spindle is set. , Cooperate with the tool change mechanism of the tool storage bin, for the machining spindle to automatically select and install the tool, and perform various processing operations on the workpiece accordingly. [0003] In order to improve the competitiveness and efficiency of traditional industries, the industry is currently focusing on expanding the ...
