Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, in particular to a frame high-precision boring device for a diamond wire cutting machine. Background Art

[0002] The diamond wire cutting machine is equipped with multiple transmission shafts for driving the diamond wire to rotate and cut objects. Among them, frames for supporting the transmission shaft are provided at both ends of the transmission shaft, so that the transmission shaft can be quickly installed on the bed of the diamond wire cutting machine. At the same time, the frames at both ends of the transmission shaft need to ensure coaxiality after installation to meet high-precision cutting. Especially for equipment for cutting semiconductors, the installation accuracy requirements are higher. Therefore, when processing pairs of frames, different processing accuracy leads to the inability to ensure coaxiality of the paired frame shaft holes after installation, making it impossible to adjust the coaxiality of the transmission shaft after installation, affecting the processing accuracy.

[0003] In the prior art, conventional boring machines bore holes independently on one frame each time they bore holes, which results in that the mounting holes of two frames used in groups after installation cannot be guaranteed to be on the same axial direction during boring, resulting in a decrease in subsequent transmission accuracy. The mounting holes of two adjacent parts cannot be kept on the same axis, which increases the resistance of the transmission process and thus reduces the transmission efficiency.

[0004] Secondly, it is difficult to find the positioning reference point during boring, resulting in the inability to ensure that the two frames are aligned each time boring, affecting the boring accuracy. Summary of the invention

[0005] The purpose of the present invention is to address the deficiencies in the prior art and provide a high-precision boring device for a frame for a diamond wire cutting machine. First, the end faces of two sets of frames installed on a positioning and adjusting unit are fine-ground, and the fine-ground surfaces are used as boring positioning reference surfaces to ensure that the two sets of frames pressed together remain on the same axis during boring, thereby improving processing accuracy. In addition, by fine-tuning the coaxial components inserted into the two sets of frames for outward expansion, the holes to be bored by the two sets of frames remain on the same axis, further improving the subsequent boring accuracy, thereby improving the processing accuracy of the synchronous processing of the cutting machine.

For the sake of simplicity, only the differences from the first embodiment are described below.
