Workpiece hole position marking tool

Abstract

The invention relates to the technical field of tool fixtures, and discloses a workpiece hole position marking tool. The workpiece hole position marking tool comprises a base plate; the base plate isprovided with vertical support columns; a substrate is fixed between the upper ends of the support columns; a support plate is fixed at the middle parts of the support columns; a lifting plate is arranged above the support plate, and is slidingly connected with the support columns; a vertical screw rod is arranged in the center of the support plate; the screw rod is in threaded connection with thesupport plate; the upper end of the screw rod is rotationally connected with the bottom surface of the lifting plate; a rotating handle is arranged at the lower end of the screw rod; a rotating baseis arranged on the lower side of the substrate; a vertical rotating shaft is arranged in the rotating base; a limiting disc is arranged at the upper end of the rotating shaft; a horizontal bracket isarranged at the lower end of the rotating shaft; a laser pen is arranged in a first connecting sleeve; emitting light rays of the laser pen are perpendicular to the base plate; a vertical punching needle is arranged in a second connecting sleeve; a slide sleeve is fixed at the bottom of the substrate; and an ejector rod is arranged in the slide sleeve. The workpiece hole position marking tool hasthe beneficial effects of convenience to use and capability of improving the workpiece hole position machining precision.

Description

technical field [0001] The invention relates to the technical field of tooling fixtures, in particular to a workpiece hole position marking tooling. Background technique [0002] Many workpieces need to be drilled for connection and assembly with other parts. The drilling of workpieces with very high precision requirements is usually processed by CNC machine tools and machining centers. However, these processing costs are high, especially for some small batches. Or for a single workpiece, the CNC machine tool needs to re-modify the processing program every time it is processed, and the processing cost is high. In the case where the accuracy requirements are not very strict, it is obviously very uneconomical to use CNC machine tools to process holes. On the one hand, the price is high. On the other hand, the processing program must be modified for each processing; Figure 10 The workpiece shown in the figure is made of 45# steel, and the connection holes on the four corners a...
