An online detection method for the oblique guide sliding surface of the oblique wedge slider

Abstract

The invention relates to an online detection method for an oblique guide sliding face of an oblique wedge sliding block. The online detection method comprises the following steps that firstly, a cylindrical base is arranged on the wedge-shaped side face of the oblique wedge sliding block; secondly, the distance L1 between the outer circumference of the cylindrical base and the vertical side of the wedge-shaped side face, the distance L2 between the outer circumference of the cylindrical base and the horizontal side of the wedge-shaped side face and the distance L3 between the outer circumference of the cylindrical base and the oblique side of the wedge-shaped side face are measured; thirdly, according to the actually-measured sizes L1 and L2 in the second step, the cylindrical base is drawn on a view of the wedge-shaped side face already drawn in drawing software, and the theoretical value L3' between the oblique side and the outer circumference of the cylindrical base in the view is measured; and fourthly, the machining error is judged according to the actually-measured value L3 and the theoretically-measured value L3'. Online detection on the machining error can be carried out on the oblique guide sliding face of the oblique wedge sliding block, detection is convenient and quick, and the detection result is precise. Once the machining error is found after detection, correction can be carried out on a numerical control machine tool without re-alignment clamping.

Description

technical field [0001] The invention relates to the technical field of on-line detection methods for molds, in particular to an on-line detection method for an oblique guide sliding surface of a wedge slider. Background technique [0002] In the field of automotive panel molds, it is very common to use a wedge slider to realize the process content of side trimming, side flanging and side shaping. The wedge slider is usually processed by a pentahedron CNC machine tool. After the CNC machine tool is finished, online inspection is required to check whether the wedge slider is qualified. The actual results of the detection are marked on the wedge slider for reference in subsequent assembly and debugging. At the same time, the dimensions that are not processed in place can be reprocessed in time. This requires that after the CNC machining is completed, the wedge slider should provide online detection before it is unloaded from the machine tool. [0003] For a long time, the onl...

Problems solved by technology

[0004] Therefore, the technical problem to be solved by the present invention is to overcome that in the prior art, when testing the wedge slider, the wedge slider must be installed on a three-coordinate testing machine tool for off-line testing. It is time-consuming and labor-intensive, and it also introduces the defect of secondary alignment error, so as to provide an online detection method for the inclined guide sliding surface of the wedge slider that can be directly detected on-line on the CNC machine tool
