Automatic set for changing tools in use for machine

Abstract

An automatic tool exchanger for machine-tool is composed of a tool disk with holes for storing tools in them, a rotary axle perpendicular to the tool disk and pivoted to top end of a telescopic rod, a telescopic rod whose lower end is fixed to one end of a supporting rod, and a tool exchanging arm whose middle position is pivoted to another end of supporting rod.

Description

Technical field [0001] The invention relates to the field of machine tools, in particular to a device capable of automatically replacing tools used on the main shaft of the machine tool. Background technique [0002] CN 1455715A discloses a machine tool with a tool spindle and a tool changer. The conveying mechanism of the tool changer has a support part that can rotate around a rotation axis that is inclined to the main axis, and is hinged on the support part. The claw that rotates on the axis of the axis is provided with some guide mechanisms on the support member, and these guide mechanisms are rotatably supported around the first axis of rotation parallel to the axis of rotation and in the direction opposite to the direction of rotation of the support member around the axis of rotation These guide mechanisms are respectively rotatably connected to a claw around a second rotation axis extending parallel to the main axis. Although it can automatically realize the function ...

[0002] CN 1455715A discloses a machine tool with a tool spindle and a tool changer. The conveying mechanism of the tool changer has a support part that can rotate around a rotation axis that is inclined to the main axis, and is hinged on the support part. The claw that rotates on the axis of the axis is provided with some guide mechanisms on the support member, and these guide mechanisms are rotatably supported around the first axis of rotation parallel to the axis of rotation and in the direction opposite to the direction of rotation of the support member around the axis of rotation These guide mechanisms are respectively rotatably connected to a claw around a second rotation axis extending parallel to the main axis. Although it can automatically realize the function of changing tools, the structure is complicated and the speed of changing tools is still not very fast. quick

For horizontal machine tools, it is necessary to be able to use many tools, and the overall weight of the cutter head that stores many tools will increase. Especially for small horizontal machine tools with movable spindles, the cutter head cannot be installed on the spindle X moving mechanism, so it can The cutter head that stores a large number of tools has to be arranged on a fixed part outside the moving mechanism, which increases the distance between the tool cutter head and the spindle. The cutter head of the medium tool that stores the necessary tools in the processing technology is installed on the moving part of the main shaft, and the tool change is adopted automatically. The tool exchange of the cutter head storing a large number of tools and the cutter head of the medium tool must be done in another On the device, it is performed when the machining is stopped, so two tool exchange devices are required, and the structure is also complicated
