Jig device for detecting adjustable flatness

Abstract

The invention discloses a jig device for detecting adjustable flatness. The jig device comprises a positioning support plate extending along a horizontal direction, and vertically placed outer supportblock and inner support block, wherein the outer support block and the inner support block are fixedly connected to the lower surface of the positioning support plate separately from left to right insequence; the lower ends of the outer support block and the inner support block are fixedly connected to a mounting bottom plate separately; and a scale side-push plate, a scale fixing seat, a positioning column and at least two flatness adjusting devices are arranged at the right end of the upper surface of the positioning support plate from left to right in sequence. The jig device is simple instructure and convenient to operate; the obtained flatness is high in the adjusting process; the accuracy of the jig device is higher than that of an existing jig for detecting the adjustable flatness; furthermore, the jig device can adapt to detection of multiple objects when applied to detection equipment and is high in adaptability, high in work efficiency and high in structure stability; thedetected data are more accurate; and the cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of jigs, in particular to a jig device for testing adjustable flatness. Background technique [0002] Fixture is a large class of tools for woodworking, ironwork, fitter, machinery, electric control and other handicrafts. It is mainly used as a tool to assist in controlling position or movement (or both). The current fixture is in the process of operation Among them, flatness refers to the deviation of the macro-concave-convex height of the substrate from the ideal plane. The problem of flatness is often not paid enough attention to. After the work is completed, the flatness will be out of tolerance, so that the accuracy cannot meet the specified requirements. [0003] There are many structures and types of fixtures with adjustable flatness in the market today, and in the mechanical field, the flatness of parts is very high when processing some parts. If the flatness is defective, the parts will be unusable,...

[0002] A fixture is a large class of tools for woodworking, ironwork, fitter, machinery, electric control and other handicrafts. It is mainly used as a tool to assist in controlling position or movement (or both). The current fixture is in the process of operation Among them, flatness refers to the deviation of the macro-concave-convex height of the substrate from the ideal plane. The problem of flatness is often not paid enough attention to. After the work is completed, the flatness will be out of tolerance, so that the accuracy cannot meet the specified requirements.

[0003] There are many structures and types of jigs with adjustable flatness in the market today, and in the mechanical field, the flatness of parts is very high when processing some parts. If the flatness is defective, the parts will be unusable, and in In some other cases where high-precision flatness requirements are required, the requirements for some fixture flatness are also increasing

[0004] However, there are certain problems in the current adjustable plane fixtures. First, the flatness of the existing adjustable plane fixtures is difficult to meet the requirements, and the precision of the adjustable flatness is not high.

Second, due to the inconvenient operation due to the complex structure, it is difficult to adjust to the required plane requirements
