Abstract

The invention relates to technical measurements. The aim of the invention is to improve the accuracy of the device by increasing the rigidity of the device. The device comprises a base with a support plane and guide grooves, a carriage with a support plane and guide grooves perpendicular to the base guide grooves. The support plane of the carriage is mounted directly on the support plane of the base. An intermediate element is placed in the guide grooves of the base and the carriage, having mutually perpendicular guides in the form of protrusions. Independent movement of the carriage in mutually perpendicular coordinates is provided by controls consisting of a rail, a shaft with a handle and a tongue, a shaft with a handle and a spindle, and a nut. 5 il.

Description

This invention relates to the field of technical measurements.

The purpose of the invention is to improve the accuracy of the adjustment by increasing the rigidity of the structure.

FIG. 1 shows the structure of the proposed device, general view; on league. 2 - the same, top view; in fig. 3 is a section A-A in FIG. 2; in fig. 4 - an intermediate element of the device; in fig. 5 is a section BB in FIG. +,

The quotation device comprises a base 1 with a supporting plane 2, guides 3, made in the form of grooves with a gear rack 4, a carriage 5 with a supporting plane 6, a threaded hole 7 and guides 8, made in the form of grooves and arranged perpendicular to the 3 guides of the base 1, an intermediate element 9 with mutually perpendicular guides, made in the form of protrusions, a shaft 10 with a tribe 11, which is mounted in the carriage 5 with the possibility of relative longitudinal movement in conjunction with a shaft-hole, and fixed t transverse displacements relative to the rail k with the end faces of the grooves of the shaft 10, and the screw 12 mounted coaxially within the shaft 10 and constituting with the threaded hole 7 in the interlock pair.

Quotation device operates as follows.

Moving the carriage 5 along one coordinate is carried out by rotating the wave-10 with the tribe 11 mounted on it, which is in engagement with the rifle k. The direction of movement will be the side surfaces of the guide grooves 8 interacting with the side surfaces of the protrusion of the intermediate element 9. The element 9 itself is stationary relative to the base 1. The carriage 5 moves along the second coordinate by the rotation of the screw 12, the direction of movement is set the side surfaces of the slots 3 of the base 1, interacting with the protrusions of the intermediate element 9f which in this case moves with the carriage 5. The screw 12 itself together with the shaft jO relative to the base 1 when moving along the second coordinate, it remains stationary relative to the base 1.

The carriage 5 with its support surface 6, when moving along any coordinate, contacts the support surface 2 of the base 1, thereby ensuring a high rigidity of the device.
