Abstract

This invention relates to technical measurements in mechanical engineering. The invention is an improvement in the accuracy and performance of measurements. The goal is achieved by the fact that, on the basis of 1, the mechanism for moving the portal 4, made in the form of guides 5,6, parallel to the guides 2 and 3, and carriages 7 and 8 with carrier 9 and 10, is fixed. in which, a quill 12 is installed with a measuring head 13. The carriages 7 and 8 are moved from the engine using mechanical gears. The carriers 9 and 10 are connected with the corresponding posts of the portal 4 with the help of communication nodes 17.18, located so that the points of application of the displacement forces lie on the direct MM passing through the center of gravity of the portal. 2 Il.

The invention relates to technical measurements in mechanical engineering and can be used to monitor large-sized products.

The purpose of the invention is to increase the accuracy and performance of measurements.

FIG. Figure 1 shows the coordinate measuring machine, the front view in figo 2 is the same, top view (partially).

The coordinate measuring machine contains a base 1 with guides 2 and 3 installed in the last portions, because the resultant force acting on the portal 4 on the mechanism of force transfer from the engine 14 to the posts of portal 4 lies at the level coinciding with the center of the portal 4 (more precisely, at the level coinciding with the center of the region of possible positions of the center of gravity of the portal) the angular momentum of the portal 4

tal 4, the mechanism of its movement, the output and braking is close to the chuli and

filled in the form of two directions 5 and 6, fixed on base 1 in parallel with guides 2 and 3, and installed in them two driving

much less than that. have known portal machines.

As a result, the machine has a smaller oscillation amplitude of the probe gauge

carriages 7 and 8 with drove 9 and 10 along the long head 13, which ultimately

Portal 4 can move the carriage 11, in which a quill 12 is installed with a measuring head 13 with the possibility of movement perpendicular to the base 1. The movement of the drive 25 carriages 7 and 8 is carried out from the engine 14 with the help of mechanical gears 15 and 16. The movement can also be carried out by separate motors for each drive carriage, the DL is electrically synchronized. The carriers 9 and 10 are connected with the corresponding posts of the portal 4 by means of the communication nodes 17 and 18 located; so that the points of application of the displacement forces lie on the forward MM passing through the center of gravity of the portal.

The work of the coordinate measuring machine has features only in the implementation of the movement of portal 4.

The movement of the portal 4 of the coordinate measuring machine is as follows.

When the engine is 14 move-. The transmission is transmitted through mechanical gears 15 and 16 to the drive carriages, ki 7 and 8. Drove 9 and 10 carriages 7 and

increases the accuracy of control of products and allows control at higher speeds.

Claims (1)

Invention Formula A coordinate measuring machine containing a base with guides, mounted in, guiding the portal, a mechanism for its movement, a carriage mounted for movement along a portal, and a quill with a measuring head mounted on a carriage with a possibility of moving perpendicular to the base, about t And so that, in order to ensure accuracy and productivity, the portal movement mechanism is made in the form of two guides, fixed on the base parallel to the portal guide, and installed corresponding drive carriages with drovers in them, which are connected with the corresponding stanchions of the portal at points lying on the straight line passing through its center t - the bristle. 8 act through the communication nodes 17 and 18 on the respective posts of the portal 4 and move it along the guides 2 and 3 of the base 1. Due to the fact that the resultant force acting on the portal 4 from the power transmission mechanism from the engine 14 to the posts of the portal 4 lies at a level coinciding with the center of gravity of portal 4 (more precisely at a level coinciding with the center of the area of possible positions of the center of gravity of the portal ), the moment of impulse of portal 4 during acceleration and deceleration is close to the boom and much less than that. have known portal machines. As a result, the machine has a smaller oscillation amplitude of the probe gauge, which improves the accuracy of control of products and allows for control at higher speeds. 5 o . five Invention Formula A coordinate measuring machine containing a base with guides, mounted in, guiding the portal, a mechanism for its movement, a carriage mounted for movement along a portal, and a quill with a measuring head mounted on a carriage with a possibility of moving perpendicular to the base, about t And so that, in order to ensure accuracy and productivity, the portal movement mechanism is made in the form of two guides, fixed on the base parallel to the portal guide, and installed corresponding drive carriages with droppers in them, which are connected with the corresponding stands of the portal at points lying on the straight line passing through its center t - the bristle.
