Description

Technical Field

[0001] The utility model belongs to the field of processing jigs and relates to a processing jig for a terminal machine pipe bearing. Background Art

[0002] The terminal machine pipe bearing is a fixed component on the terminal machine. According to the assembly requirements, it is necessary to process the large surface of the workpiece with a width of 24 and ensure the finish Ra2.5. The existing workpiece is a special-shaped part, and both ends need to be fixed separately, but one end cannot be fixed by hard fixation because it is made of a blank surface. If hard positioning is used, it will cause processing dislocation. For the processing fixture of the workpiece, if the clamping force of the processing fixture on the workpiece is small, it is easy to cause the processing part of the workpiece to be dislocated and deformed, and the finish requirements cannot be guaranteed. If the clamping force of the processing fixture on the workpiece is too large, it is easy to cause the width 24 size to be lost. Therefore, it is urgent to develop a red processing fixture to solve the above problems. Utility Model Content
