Embodiment 1

[0029] Such as Figure 4-5 As shown, the rotating shaft 6-3 is a cylinder with a plane 6-3-1a on the outer surface, and the plane 6-3-1a extends along the axial direction of the rotating shaft 6-3, and the rolling of the roller 7 The axis is perpendicular to the axis of the rotating shaft 6-3, and the roller 7 is rollingly connected with the plane 6-3-1a.

Embodiment 2

[0031] Such as Figure 6 As shown, the outer surface of the rotating shaft 6-3 has a convex key 6-3-1b, and the convex key 6-3-1b extends along the axial direction of the rotating shaft 6-3, and the rolling axis of the roller 7 Perpendicular to the axis of the rotating shaft 6-3, the roller 7 has a keyway 7-1, and the roller 7 rolls and is keyed to the convex key 6-3-1b.

Embodiment 3

[0033] Such as Figure 7 As shown, the outer surface of the rotating shaft 6-3 has a convex key 6-3-1b, and the convex key 6-3-1b extends along the axial direction of the rotating shaft 6-3, and the roller 7 has several , and the rollers 7 are evenly distributed on both sides of the convex key 6-3-1b, and the rollers 7 are rollingly connected with the convex key 6-3-1b and the outer surface of the rotating shaft 6-3.

[0034] The working process of the CNC machine tool quick change mechanism of the present invention is as follows:

[0035] First of all, the pushing part 11 of the translation mechanism, such as a cylinder, can push the push plate 12 to move on the guide rail 10, thereby driving the rotation drive mechanism, the up and down drive mechanism, and the tool changing part 1 to move on the guide rail 10 at the same time, so that the tool changing part 1 can move on the guide rail 10. Position switching between the tool magazine 13 and the tool parts for the CNC machi...

Abstract

The invention relates to a tool quick changing mechanism for a numerically controlled machine tool, which comprises a tool changing part, a rotating drive mechanism and an up and down driving mechanism. The rotating drive mechanism includes a worm wheel, a worm, and a conversion sleeve. The driving mechanism includes a jacking part and a conversion shaft. The conversion shaft is matched with the internal clearance of the worm wheel. The conversion shaft includes a force receiving part, a middle bearing and a rotating shaft. The jacking part pushes the force receiving part to move up and down. connected, the conversion sleeve is provided with a pushing part for pushing the rotation shaft to rotate, and the rotation shaft drives the tool changer to rotate and move up and down. The tool quick change mechanism of the numerical control machine tool of the present invention, the rotation drive mechanism and the upper and lower drive mechanism are integrated without interfering with each other, and the lifting and rotation of the tool changing parts can be realized at the same time. To and fro position switching between the library and tool parts for CNC machines.

Description

technical field [0001] The invention relates to a fast changing mechanism for a tool of a numerical control machine tool. Background technique [0002] The machine tool generally has an automatic tool changer. The automatic tool changer has a tool magazine and a tool changing arm. The tool magazine has many tool pockets. The tool pockets hold the tool and move circularly along a specified path. Position the tool in the ready position and send it out to the tool changer outside the tool magazine. In the machine tool industry, multi-station tool holders can realize tool change, but the tool does not have its own power, and the power head of the machine tool can only drive one tool. Therefore, the traditional tool holder structure makes the tool change process extremely complicated and cannot be realized. Fast and efficient tool change affects processing efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order t...
