The to-be-solved technical problem of the utility model provides a simple structure, convenient to use can effectively improve detection efficiency, reduce detection error's straightness accuracy detection utensil.
In order to solve the technical problem, the utility model discloses an utensil is examined in straightness accuracy detection, including the upper limit plate of bottom plate and bottom plate top, be provided with a supporting shoe between the left and right sides edge of bottom plate and upper limit plate respectively, distance between two supporting shoes is greater than the length of bar-shaped class work piece, and the highly equal bar-shaped class work piece diameter of two supporting shoes rolls from making bar-shaped class work piece from bottom plate and upper limit plate between.
The width of the bottom plate is larger than that of the upper limiting plate.
The upper limiting plate spans the middle part of the bottom plate in the width direction.
The upper limiting plate is provided with an observation groove through which whether the rod-shaped workpiece passes in a rolling manner or not can be observed.
The upper limiting plate is made of toughened glass.
Mounting holes are formed in the left end and the right end of the upper limiting plate, and the upper limiting plate is fixedly mounted on the two supporting blocks through fasteners penetrating through the mounting holes.
After the structure is adopted, the checking fixture formed by the bottom plate and the upper limiting plate is designed through comprehensive analysis and consideration of the tested piece, so that the tested piece is detected in a rolling mode through the checking fixture, the standard flatness of the checking fixture is ingeniously utilized, the straightness of the tested piece is detected, the structure design is simple, the application range is wide, the use is convenient, the straightness can be effectively measured visually during measurement, the measurement straightness error is reduced, the detection time is effectively shortened, the detection efficiency is greatly improved, and the practicability is very high.

Detailed Description
The present invention is specifically described below by way of exemplary embodiments. It is to be understood, however, that the structures and features of one embodiment may be beneficially incorporated in other embodiments without further recitation.
In the description of the present invention, it should be noted that the terms "inside", "outside", "upper", "lower", "front", "rear", and the like indicate orientations or positional relationships based on positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention.
The first embodiment is as follows:
as shown in the figures, the straightness detection gauge of the utility model comprises a bottom plate 1 and an upper limiting plate 2 above the bottom plate, wherein the upper limiting plate 2 is made of toughened glass, as can be seen from the figures, the width of the bottom plate 1 is larger than that of the upper limiting plate 2, the upper limiting plate 2 stretches across the middle part of the bottom plate in the width direction, so as to provide enough rolling space for a measured piece and improve the detection accuracy by utilizing the narrow width of the upper limiting plate, a supporting block 3 is respectively arranged between the edges of the left side and the right side of the bottom plate 1 and the upper limiting plate 2, when in installation, mounting holes can be arranged at the left end and the right end of the upper limiting plate 2, the upper limiting plate 2 is fixedly arranged on the two supporting blocks 3 by screws passing through the mounting holes, the left side and the right side are the left side and the right side defined by the direction in the figures, the width direction is the up-down, the height of the two supporting blocks 3 is equal to the diameter of the rod-shaped workpiece, so that the rod-shaped workpiece can roll through the space between the bottom plate 1 and the upper limiting plate 2, and whether the rod-shaped workpiece passes through in a rolling mode can be observed through the observation groove.
Example two:
as shown in the figures, the straightness detection gauge of the utility model comprises a bottom plate 1 and an upper limiting plate 2 above the bottom plate, wherein the upper limiting plate 2 is provided with an observation groove, as can be seen from the figures, the width of the bottom plate 1 is larger than that of the upper limiting plate 2, the upper limiting plate 2 stretches across the middle part of the bottom plate in the width direction, thereby providing enough rolling space for a measured piece and improving the detection accuracy by utilizing the narrow width of the upper limiting plate, a supporting block 3 is respectively arranged between the edges of the left side and the right side of the bottom plate 1 and the upper limiting plate 2, when in installation, mounting holes can be arranged at the left end and the right end of the upper limiting plate 2, the upper limiting plate 2 is fixedly arranged on the two supporting blocks 3 by screws passing through the mounting holes, the left side and the right side are the left side and the right side defined by the direction in the figure, the width direction is the up-down, the height of the two supporting blocks 3 is equal to the diameter of the rod-shaped workpiece, when the straightness is used, the measured piece (the rod-shaped workpiece) rolls through the checking fixture, if the measured piece (the rod-shaped workpiece) can roll smoothly between the bottom plate 1 and the upper limiting plate 2, the straightness of the product meets the requirement, if the measured piece cannot roll smoothly between the bottom plate and the upper limiting plate, the straightness of the product is poor, and the upper limiting plate is made of toughened glass, so that the rolling condition of the measured piece can be visually observed, and the detection precision is further improved.
