Embodiment Construction

[0023] The present invention discloses 3 embodiments, which are described as follows in conjunction with the accompanying drawings:

[0024] 1. In figure 1 In the shown embodiment, the main shaft and the tool (3) are connected in series with the circular arc gantry structure (2) through the small sliding seat (6) and the large sliding seat (4), and the main shaft (3) can perform an arc motion of more than 180 degrees ( figure 2 image 3 ); the main shaft (3) performs rotary motion relative to the small slide (6), the small slide (6) moves up and down relative to the large slide (4), and the large slide (4) conforms to the guide rail of the arc gantry structure (2) Arc motion. The corresponding processing motion can be obtained by controlling each component to do a single or joint action.

[0025] 2. In Figure 4 In the shown embodiment, the main shaft and the tool (4) are connected in series with the guide rail of the circular gantry structure (1) through the small slidin...

Abstract

The invention relates to a circular arc or circular gantry structure for a machine tool, a robot and a mechanical measuring machine. A traditional track gantry frame comprising three components (one transverse beam and two upright posts) is designed and manufactured into a circular arc or circular gantry structure component, then the circular arc or circular gantry structure component is connected with a main shaft, a main shaft box or other movement components in series, and the main shaft, the main shaft box or other movement components are controlled to make required relevant movement and direction movement on a track of the circular arc or circular gantry structure component, thereby three-dimensional translation and three-dimensional movement output can be realized. The structure can be used as the basis of the actuating mechanisms of the machine tool, the robot and the mechanical measuring machine.

Description

Technical field [0001] The invention relates to the fields of machine tools, robots and coordinate measuring machines, in particular, it can be used for arc or circular gantry structures of numerically controlled machine tools, handling robots and mechanical measuring machines. Background technique [0002] Currently known lathes and machinery have the following types in structure: [0003] 1. The gantry structure of the known CNC machine tools is a square door-shaped series structure, and is composed of 3 parts (2 columns, 1 beam) to form a gantry, and the 3 parts are used for manufacturing and assembly. , inspection and other production links have brought many difficulties; a machine tool characterized by a gantry is composed of 3 parts (2 columns, 1 beam), especially a gantry machining center, which requires more than two axes when doing arc machining movements Linkage interpolation can only be completed, and the trajectory of the machine tool (3-axis gantry machining ce...
