Abstract

The invention in a device comprising an intermediate support placed on the base by means of a pivot unit with chassis attachment points and brackets with block attachment nodes pivotally mounted on an intermediate support by means of arm pivot knots, each pivot unit is made in the form of a head, a rotatable element, a bolt and spring-loaded nuts, with the head and the rotary element placed on the bolt coaxially, and the nz of the mating surfaces of the head and the rotary element made radial grooves 6 or

Description

The invention relates to radio electronics and can be used in the installation and adjustment of boards (blocks) of electronic equipment (hereinafter REA).

The purpose of the invention is to improve the operational capabilities by independently changing the position of the REA adjustable blocks relative to each other.

Fig. 1 shows the kinematic diagram of the device proposed; Fig. 2 shows the intermediate bearing rotation unit and one of the bracket rotation nodes in isometry; FIG. 3 is a section along the A-A in FIG. 2, FIG. 4 is a view B in FIG. 3, FIG. 5 is a section B-B in FIG. 3; Fig 6 is a cross section of GT in Fig 5.

A device for mounting and adjusting electronic equipment blocks contains an intermediate support 3 with a chassis fastening assembly 4 (not shown) of L-shaped brackets placed on the base 1 via the swivel assembly 2.

5 with fastening units 6 of REA units (not shown), pivotally mounted on the intermediate support 3 by means of nodes 7 of rotation of the brackets (see FIG. 2).

The node 2 of rotation of the intermediate support 3 is made in the form of a head 8 fixed on the base 1, a pivot element 9, a bolt 10 and a spring-loaded nut 11, the head 8 and the pivoting element 9 being mounted on the bolt 10 coaxially, and the intermediate support 3 is fixed on a pivoting element 9, with radial grooves 12 (see FIG. 3) on the mating surfaces of the head and the pivoting element 9.

Elements of a slant

the intermediate support 3 are fastened to each other by a bolt 10 and spring-loaded with each other by a spring 13 coaxial with the bolt 10 and abutting one end against the washer 14 held by the pin from being moved along the axis of the bolt 10 between the end of the washer 14 and

The end of the sleeve 15 mounted on the spring 13, a gap 16 is formed, equal to or greater than the height of the radial grooves 12, made on the mating surfaces of the head 8 and the rotary element 9 and used to enhance the adhesion between these surfaces.

A bolt 11 is screwed on the bolt 10, which contacts its end with the end face of the washer 14 and serves to firmly fix the elements of the turning unit of the intermediate support 3 by further screwing it up to the backlash-free state between the end of the nut 11, the washer 14 and the sleeve 15 (i.e. . The gap 16 in this case is zero).

The node 7 of the rotation of each bracket 5 is made similar to the node 2 of the rotation of the intermediate support 3, while the head 17 of the node 7 of the rotation of the bracket 5 is fixed to the intermediate support 3, and on the rotary element 18 of this node is fixed the bracket 5.

The elements of the L-shaped bracket rotation unit 7 are bolted with each other 19 and spring 20 relative to each other by a spring 20 coaxially with the bolt 19 and abutting one end against a washer 21 held by a pin (not shown). At the same time, a gap 23 is formed between the end face of the washer 21 and the end face of the sleeve 22, mounted on the spring 20, equal to or greater than the height of the radial grooves 24 formed on the mating surfaces of the head 17 and the rotary element 18 and serving to enhance the adhesion between these surfaces,

A bolt 19 is screwed on a nut 25, which contacts with its end face with the end face of the washer 21 and serves for rigid fixation of the elements of the turning unit of the G-shaped brackets 5 by further tightening it to the backlash-free state between the end face of the nut 25, washer 21 and sleeve 22.

A device for mounting and adjusting electronic equipment blocks works as follows.

If necessary, transfer the unit to

A new position is rather manual, overcoming the friction forces in the mating elements with radial grooves, transfer either the intermediate support 3, or the L-shaped bracket 5, or both of them to the desired position.

If it is necessary to firmly fix the REA block in a predetermined position, then it is enough to tighten the corresponding nuts 11 (or 25) for this, choosing gaps

16 (or 23). At the same time, the grooves 12 (24) of the head of the rotation assembly come into contact with the depressions of the rotation element of the rotation assembly, ensuring a reliable fixation of the elements,
