Description

Technical Field

[0001] The utility model relates to the technical field of multi-axis indexing tables, and particularly relates to a high-precision multi-axis indexing table. Background Art

[0002] A multi-axis indexing table is a mechanical device used for precisely positioning and rotating workpieces, commonly found in machining and manufacturing; it allows indexing operations on multiple axes to achieve complex cutting, engraving, and assembly tasks, and has the characteristics of multi-axis operation and high precision.

[0003] During the machining and manufacturing process, a multi-axis indexing table is used to clamp a workpiece, rotate, index, and position it for easy machining of the workpiece. However, there are some deficiencies in the existing multi-axis indexing tables during use: especially when cutting and engraving workpieces, some debris is likely to fall into the gaps of the rotating shafts on the base plate, which may cause the base plate to run unbalanced, increase wear, affect the machining accuracy of the workpiece, and even may cause equipment failures or damages; therefore, we propose a high-precision multi-axis indexing table to solve the above problems.

[0007] Preferably, the two cleaning rod rings are respectively located in the two gaps between the machine base and the base plate, and both sides of the cleaning rod rings are respectively rotatably attached to the inner walls between the machine base and the base plate. When the two cleaning rod rings rotate in the corresponding gaps between the machine base and the base plate, the debris falling into the two gaps is cleaned, avoiding the situation that the base plate runs unbalanced due to the debris falling into the two gaps between the base plate and the machine base.

[0008] Preferably, the rotation driving mechanism includes a stepping motor and a driving rod. One side of the machine base is fixedly installed with a stepping motor, and one end of the driving rod is fixedly installed at the output end of the stepping motor. The other end of the driving rod is rotatably installed on the inner wall of the corresponding side chamber. By starting the stepping motor, the two driving wheels on the driving rod are driven to rotate.

[0009] Preferably, the transmission mechanism includes a driving wheel and a belt. The driving wheel is rotatably installed in the side chamber, and the driving wheel is fixedly installed on the driving rod. The same belt is sleeved between the driving wheel and the corresponding rotating ring wheel, which facilitates the driving wheel to drive the rotating ring wheel to rotate through the belt.

[0010] Preferably, two slopes are provided on the inner wall of the bottom side of the machine base, and the two slopes on the machine base are symmetrically arranged, which facilitates the scraped debris to slide down along the two slopes on the machine base.

[0011] Preferably, box grooves are provided on both slopes, and collection boxes are inserted and installed in the two box grooves. The collection boxes are used to collect the debris sliding down on the slopes, which is convenient for subsequent unified treatment.
