Description

The invention is related to measurement technology.

A device for measuring the relative position of the surfaces is known, consisting of a base with a prism attached to it with a stop and a bracket, on which an angular lever and a measuring device with a tip are mounted. The angular lever, the first arm of which is in contact with the surface to be tested, and the second arm with the tip of the measuring device, has the ability to turn the prism 1 in the bisector plane.

However, it is not possible to check the face runout of a part with a known device, and this limits its technological capabilities.

It is also known a device for measuring face beats, consisting of a plate with mounted prisms and a tripod, on which the measuring device is fixed and the stop contacting with the end surface of the measured part 2.

A disadvantage of this device is that the measuring device cannot come into contact with the end surface of the hole of the part and measure the radial runout of the surface of the holes, which also limits the technological capabilities of the device.

The closest technical solution to the invention is a device for measuring the relative position of the surfaces, comprising a base, a prism mounted thereon, a housing with a measuring unit and an angular lever mounted rotatably in the bisector-like prism, and an emphasis. One arm of the angular lever is designed to come into contact with the surface to be contacted, and the second arm is in contact with the measuring unit, and an additional contact is made on the second lever arm from the prism side so that the distance between it and the first arm contact along the prism axis is smaller and focusing the prism 3.

The disadvantages of this device are the impossibility of measuring face beats in parts with stepped holes, which reduces the technological capabilities, as well as the need to move the part along its length to measure the face beats, which leads to an increase in auxiliary time, a decrease in measurement performance.

The purpose of the invention is to expand the technological capabilities and increase the productivity of the measurement device.

. This goal is achieved by the fact that a device for measuring the relative position of surfaces, comprising a base, a prism mounted thereon, a housing with a measuring unit and an angular lever mounted rotatably in the bisector plane of the prism, and an emphasis, is provided with an axially spring-loaded plunger installed in bisecting plane of the prism with the possibility of fixation in the body, in the corner lever is spread on the plunger with the possibility of fixation relative to it.

FIG. 1 shows a device for

0 measuring relative position on top of the bones, side view; in fig. 2 - the same view

from above; in fig. 3 is a section BB in FIG. 2;

in fig. 4 - angle lever in position

measuring the open end of the part;

5 in FIG. 5 - the same, in the position of measuring the radial beat in the stepped bore; in fig. b - the same, in the position measurement of the end beats in the stepped hole; in fig. 7 and 8 are two positions of the screw, allowing to measure the butt and radial runout respectively.

On base 1, a prism 2 is installed with a tested part 3 and a housing 4 in which plunger 5 is installed, and in it rotatably on axis 6 is installed

5 angular lever 7 and fixation elements in the form of a rocker arm 9 and a screw 10 rotatable around the axis 8. At one end of the rocker arm 9 there is a finger 11 installed on the other end of the rocker arm 9 and a finger 12 and 13 on the other.

0 with the ability to interact with the conical surface B of the screw 10 (FIGS. 7 and 8), the finger 13 is intended to limit the rotation of the rocker arm 9 towards the angular lever 7. The end face G of the screw 10 can interact with the lateral surface of the body 4. In the sleeve 14, placed in the housing 4, using a screw 15 is fixed indicator head 16.

The angular lever 7 has three arms, one shoulder is in contact with the indicator head 16, the second shoulder is directed along the axis of the plunger 5 and is intended to measure the face runout of the inner end of the stepped hole of the part 3 (Fig. 6) and the radial runout of the hole (Fig. 3 and 5 ), the third shoulder is intended for measuring 5 end face beats in parts with a through hole (Fig. 4).

On base 1, a strip 17 is installed to limit the movement of the housing 4 during the measurement. A support 18 is installed on the housing 4 to restrict the movement of the part 3 during the measurement process and which can move along and perpendicular to the axis of the plunger 5 (Fig. 1-6).

The plunger 5 is spring-loaded in the axial direction by a spring 19, pressed by

5 of the adjusting screw 20 (Fig. 3).

The device works as follows. The tested part 3 is mounted on the prism 2 and pressed against the stop 18, the body 4 is moved against the stop into the bar 17, while the angular lever 7 comes into contact with the hole of the tested part 3.

When measuring the radial beating, the screw 10 is wrapped up to the stop of its end surface G in the side surface of the housing 4 (Fig. 1, 3, 5 and 7). The plunger 5 in this position is fixed relative to the housing 4, and the angular lever 7 transfers the magnitude of the radial beating of the part 3 to the indicator head 16 when the part is rotated through 360 °.

When measuring the face beats, the screw 10 is unscrewed from the plunger 5 until it, with its conical surface B, presses the finger 12, as a result of which the beam 9 rotates around axis 8 and the finger 11 presses the angular lever 7 to the surface of the plunger 5 (Fig. 4, 6 and 8). Thus, the plunger 5, together with the angular lever 7, forms a rigid system, and the amount of the end beats of the part 3 is transferred to the indicator head 16 by axial movement of the plunger 5 when the part is rotated 360 °. The screw 10 is in this position retracted from the surface of the housing 4 and does not displace the movement of the plunger 5.

The position of the parts of the device when measuring the radial and face beats in parts with a through hole is shown in FIG. 1, 3 and 4. The position of the parts of the device when measuring the radial and face beats in parts with a stepped hole is shown in FIG. 5, 6.

The proposed device, by providing the ability to measure the relative position of surfaces in various types of parts, allows one to expand the technological capabilities and improve the measurement performance by reducing the auxiliary time for readjustment.
