Description

Technical Field

Some large equipment requires a long stroke. Since the length of a single linear guide rail is limited, the linear guide rail needs to be spliced, so the splicing surface needs to be processed on the end face. The processed end face of the spliced guide rail has extremely high requirements. To prevent axial elongation caused by thermal expansion during the movement of the linear guide rail, the splicing gap is between 0.03 mm and 0.05 mm. At the same time, it is necessary to ensure that the distance between the mounting holes on both sides of the splicing part is equal to the standard hole pitch.

[0003] The existing equipment for processing the end face of a guide rail is manually positioned. The distance between the processed end face of the linear guide rail and the nearest fixed hole is determined by a vernier caliper to determine the required processing size. After the linear guide rail is fixed, the distance from the processed end face of the linear guide rail to the grinding wheel of the grinding machine is measured, and the measured value is input into the central control terminal of the grinding machine, and the grinding amount is input. After the grinding machine is started, processing is carried out, and after the processing is completed, manual inspection is carried out.
