Hole and end face perpendicularity test tool

Abstract

The invention discloses a tool for detecting the hole and end face perpendicularity, and belongs to the technical field of machining detection devices. Three positioning blocks for axial positioning installation of an inner diameter face of a workpiece hole to be detected are circumferentially arranged on a test tool body, wherein at least one positioning block is arranged on the test tool body in the mode of being capable of being adjusted in the radial direction. A test gauge capable of rotating around the axis is further arranged on the test tool body. The axis formed by the three positioning blocks and the rotating axis of the test gauge are parallel or coincide with each other. The hole and end face perpendicularity test tool is ingenious in concept, the axis of the workpiece hole is used as the detection positioning reference creatively, the end face is used as a detection element, data obtained through detection are hole and end face perpendicularity tolerance values, detection is rapid, operation is easy and convenient, and data are visual and efficient; when the test tool is used for connecting rod end face perpendicularity detection, the detection positioning reference and the detected element coincide with the connecting rod design reference, the problem that a traditional test means is influenced by connecting rod hole shape errors is avoided, and the detection precision is greatly improved.

Description

technical field [0001] The invention relates to a detection tool, in particular to a tool for detecting the perpendicularity between a hole and an end face, and belongs to the technical field of mechanical processing detection devices. Background technique [0002] In mechanical processing, it is often necessary to detect the perpendicularity of the hole and its end face, the most typical is the large hole of the connecting rod and the perpendicularity of the end face. [0003] Take the large hole and end face verticality detection operation of the connecting rod as an example: the existing detection technology for the verticality of the end face of the connecting rod mainly uses a square box, a flat plate, a height gauge and a lever hundred (thousand) submeter for combined detection, and the end face of the big end of the connecting rod As the detection basis, the generatrix of the large hole of the connecting rod is used as the detection element. Since this test benchmark...

Problems solved by technology

[0004] The detection efficiency of this detection method is low, the detected data is greatly affected by the shape error of the large hole of the connecting rod, and the accuracy of the detection result is also limited by the operator's detection operation level

Especially with the advancement of technology, there are higher requirements for the processing and assembly precision of connecting rods, and with the improvement of the production efficiency of connecting rod processing, this traditional detection technology of perpendicularity between holes and end faces has become more and more difficult to adapt to production needs
