Description

(54) MULTI-POSITION ASSEMBLY AUTOMATIC MACHINE

one

The invention relates to mechanical engineering, in particular to the automation of assembly processes.

A multi-position assembly machine is known, for example for assembling a terminal with a spring of a setting device of a thermostat containing loading heads with grippers, a multi-position rotary table with fixing units of the base part, assembly technological heads with mechanisms for moving them from the central shaft of the automatic drive and control mechanisms 1.

A disadvantage of the known automaton is the complexity of its design, large tabarites and inconvenience of maintenance.

The purpose of the invention is to simplify the design and improve access to the place of loading parts.

The goal is achieved by the fact that the automaker is equipped with a cam located on the central drive shaft, a slider, kinematically connected with axes intersecting on the axis of the central drive shaft, with the middle guide mounted equally spaced from the two extreme ones.

At the same time, the loading heads are installed with the possibility of synchronous movement along the extreme guides, and on the last guide there is a slider connected through the additionally introduced traverse to

5 boot heads.

FIG. 1 shows the automatic, general view; in fig. 2 - mechanism for loading the spring and terminals; in fig. 3 shows section A-A in FIG. 2; in fig. 4 - spring loading head.

The multi-position assembly machine has a rotary table 1, on which the fixing units of the base part 2, the mechanisms for loading components and the assembly mechanism are fixed.

15 The spring loading mechanism 3 and the terminals consists of a bracket 4, on which the guides 5 are fixed, angled and converging on the axis of the central shaft of the drive 6. The middle guide is mounted equidistant from the two extreme ones. The loading heads 7 and 8 are designed to transfer the terminals 9 and the springs 10 from the trays 11 and 12 to the fixing unit 13 and are installed with the possibility of synchronous movement along the outer rails 5.

On the middle guide, a slider 14 is connected, connected through the yoke 15 with the loading heads, and through the levers 16, 17 and 18 to the cam.m 19 mounted on the central drive shaft. The loading heads 7 and 8 are provided with grippers 20, and the gripping of the loading rOviOBKH 7 is rotatable from the stop 21 mounted on the | 5 auger.

The machine works as follows.

When the cam 19 is rotated, the levers 16, 17 and 18 move the slider 14 along the guide 5. In this way, the boot heads 7 and 8 move synchronously along the respective extreme directions. The heads move to the stops, which determine their extreme positions.

 In one extreme position, the heads are stopped under the trays 12, in the other, above the fixing unit 13.

When the terminals are loaded into the slot of the fixation unit, the loading head 7, moving to the extreme position, rests against the stop 21 and the grip 20 through the rotation mechanism, made in the form of a rack-and-pinion gear, rotates by 90 °. By changing the length of the stop 21, you can change the angle of rotation of the grip.

The application of the invention will improve productivity and improve build quality.
