The invention relates to technical measurements in mechanical engineering and can be used in CNC machines, coordinate measuring machines and robots.

The purpose of the invention is to improve accuracy.

Fig. 1 shows a converter with a clear view, general view; per g, 2 - transducer, transverse section in the middle of the head.

The linear displacement transducer includes a housing of 1 L-section, on the wide side of which there is a scale made of rulers 2, and on the ends of the housing there are fixed rectangular posts 3 having openings for fastening the transducer on the equipment base. The transducer also contains a leash 4 with bracket 5, covering the head 6 ,. connected with a bracket 5 by two drovers 7, fixed by hinges with one ends at a common point in the form of a pin 8 on the head 6, the other ends of the droppers are fixed also hinged to the pins 9 and 10 mounted on the uprights 3 of the brackets 5. The head 6 presses With the help of a wire spring 11 fixed to the bracket 5 and a pin 8 to the housing bases, the housing I of the converter is closed with a nut 12. On the inner surfaces of the housing 1 and the lid 12, rubber plate seals are installed near the open part of the converter

The converter works as follows.

The housing 1 of the converter is fixed on the equipment frame.

Thus, the longitudinal axis of the body is aligned along the axis of the measured displacement. The lead 4 is attached to a movable piece of equipment, the movement of which is measured by the converter. In this case, the head 6 connected to the driver through the carrier 7 and the bracket 5 presses against the bases of the housing and moves along the scale established in the housing 1, and determines the size of movement on the converter's scale. By arranging the scale from separate lines 2, it is possible to make matching the rulers on the longitudinal comparator, to ensure that the error of the converter does not exceed the error of the worst of the individual lines. The proposed design of mounting the head with two identical carriers eliminates the longitudinal movement of the head at its transverse displacement relative to the longitudinal axis of the transducer.
