Description

Technical Field

[0001] This utility model relates to the technical field of machining equipment, specifically to a multi-axis worktable and machine tool. Background Technology

[0002] A machine tool is a machine used to manufacture machines; it is also called a machine tool or machine tool machine. In related technologies, machine tools are generally three-axis machine tools, meaning they have alignment mechanisms in three different directions of movement. This allows the workpiece and the machine head to move relative to each other in three directions. However, this results in dead zones in the workpiece and low production efficiency. Furthermore, in related technologies, the alignment mechanisms occupy a large space, leading to a large overall machine tool size and poor structural compactness.

[0003] To address the aforementioned issues, publication number CN202122386443.7 discloses a multi-axis worktable and machine tool, comprising: a base, a saddle, a platform, and a rotary table. The base has a first receiving groove; the saddle is disposed on the base, and a first alignment mechanism is provided between the saddle and the base, the first alignment mechanism being used to move the saddle horizontally; the first alignment mechanism is at least partially located within the first receiving groove; additionally, the saddle has a second receiving groove: the saddle can move horizontally via the first alignment mechanism, and the platform can move horizontally in another direction via the second alignment mechanism, giving the rotary table two directions of movement. Furthermore, the main body can rotate via a rotation mechanism, further adjusting the placement angle of the workpiece placed on the main body, increasing the machining angle, and improving production efficiency. Furthermore, this multi-axis worktable has a relatively compact structure.

[0004] However, this multi-axis worktable still has the following problems: 1. The existing worktable can only be used for multi-axis movement of a single workpiece, cooperating with the machining spindle to process a single workpiece. It cannot perform synchronous movement compensation or individual independent movement compensation for multiple workpieces, thus failing to meet the multi-station machining needs of existing machine tools. 2. The existing worktable lacks a protective cover for guiding fluid. During machining, chips or cutting fluid may flow into the moving mechanism, potentially affecting the stability, accuracy, and service life of the moving mechanism. Utility Model Content
