Multi-shaft cascaded mechanical drilling machine

Abstract

The invention relates to a multi-shaft cascaded mechanical drilling machine, comprising a machine body. A main beam and an auxiliary beam are mutually parallel and fixedly arranged on the machine body. At least three connection supporting points are arranged between the main beam and the machine body. An operating platform is further fixedly arranged on the machine body and is provided with a working component for assembling a circuit board. A three-coordinate axis movement component for driving the working component to move in an X direction, a Y direction and a Z direction is hung between the main beam and the auxiliary beam. The three-coordinate axis movement component comprises a working shaft group, an X coordinate driving component and a Y coordinate driving component, wherein the working shaft group consists of a plurality of working shafts and is used for driving the working component; the X coordinate driving component is used for controlling the working shaft group movement in the X direction; and the Y coordinate driving component is used for controlling the working shaft group movement in the Y direction. Each working shaft in the working shaft group is respectively provided with a Z coordinate driving device for driving the working component movement in the Z direction. The X coordinate driving component, the Y coordinate driving component and the working shaft group are connected in a framework manner.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, and more specifically, relates to a multi-axis cascaded mechanical drilling machine. Background technique [0002] Mechanical drilling rig is one of the main processing machines in the Printed Circuit Board (PCB) industry. Its main performance evaluation indicators are: efficiency, precision and processing range. In order to improve the processing efficiency of mechanical drilling rigs, multi-axis cascading structures are generally used. However, the current multi-axis cascading mechanical drilling rig has the following problems: 1. The volume of the machine is large; 2. The span of the cascade shaft beam is large (nearly 4 meters), and the deformation is large; 3. The length of the machine table The direction size is also relatively large (more than 3 meters), resulting in a large swing angle error in the direction of guide rail running; 4. The multi-axis cascade structure is diff...

AI Technical Summary

Problems solved by technology

However, the current multi-axis cascading mechanical drilling rig has the following problems: 1. The volume of the machine is large; 2. The span of the cascade shaft beam is large (nearly 4 meters), and the deformation is large; 3. The length of the machine table The direction size is also relatively large (more than 3 meters), resulting in a large error in the swing angle of the guide rail running direction; 4. The assembly of the multi-axis cascade structure is difficult and the rigidity is low

Moreover, due to the large length of multiple parts and components of the machine, thermal deformation has a significant impact on accuracy

Therefore, the mechanical drilling rig with multi-axis cascade structure in the prior art cannot guarantee the processing efficiency and precision at the same time, and needs to be improved and improved.
