Description

The invention relates to a measurement technique in machine-building production, in particular for measuring the beating of parts directly at the workplace.

Known surface gauge containing the base; with a stand on which a clutch with a screw in the form of a double curved lever and a fastening screw is mounted along it. However, the device does not allow to obtain visual information about the beating of the part in the monitoring process.

The closest to the proposed device in terms of design and principle of action is a device for measuring the relative position of surfaces, comprising a base with a vertical stand, on which is mounted on an axis with the possibility of rotation and a spring-bent two-shouldered measuring arm with a measuring contact, and measuring knot. The main disadvantage of such a device is the limited measuring range. In addition, the design of the device eliminates the possibility of conveniently obtaining visual information about the beating of the part during operation, which leads to an increase in the time of control.

The purpose of the invention is to expand the measuring range, and increase the convenience and productivity of the measurement.

The goal is achieved by installing the axis of rotation of the measuring curved two-arm lever on the rack with the ability to move along it and supplying it with a position fixing device, making the measuring curved extension arm unequal-shouldered. rotating roller.

Figure 1 shows the device, a general view; figure 2 - the same top.

The device comprises a base 1 with a stand 2, on which a coupling 3 with a measuring curved two-arm lever 4 is mounted for movement along the rack and having a possibility of rotating about an axis 5. The coupling 3 is equipped with a fastening screw 6 and a measuring unit made in the form of a frame 7 with a scale 8. The measuring curved double-shouldered lever is made unequal to increase

convenience of measurement and is spring-loaded in the plane of its rotation by the spring 9.

At one end of the measuring curved two-arm lever 4 there is a measuring contact, made in the form of a roller 10 mounted on the axis of rotation 11. The measuring curved double-arm lever 4 is fixed on the axis 5 by means of a spring 12 and fasteners 13 and 14.

The device works as follows.

To adjust the part for boring, i.e. To check its beating, the device is installed with the base 1 on the frame of the machine (not shown) from the end of the part. Moving the clutch 3 to the stand 2 adjusts the device to the nominal size, pressing the roller 10 to the surface of the part with a spring 9, creating the necessary measuring force, and then fixing the position of the clutch 3 with the screw 6. At the same time, the shape of the measuring arm 4 allows you to avoid influence of burrs and shoulders at the end of the part, on the other hand, place the measuring unit, made in the form of frame 7 with scale 8 in a convenient place, which allows setting the part for boring directly from the working th place without additional movements.

Thus, the use of the proposed device allows extending the measurement range, increasing the convenience and productivity of the measurement as compared with the known.

Fo rumula and 3 o bre i n A device for measuring the beat, containing a base with a stand on which is mounted on an axis rotatably spring-loaded in the plane of rotation measuring curved two shoulders lever with measuring contact and measuring node, characterized in that, in order to expand the measurement range, increase convenience and measure productivity, the axis of rotation of the measuring curved two-arm lever is mounted on the stand with possibility. displaced along it and provided with a position fixing device, the measuring curved two-arm lever is made unattractive with an additional bend in the plane perpendicular to its rotation plane, and (the measuring contact is made in the form of a rotating roller.
