Abstract

The invention relates to the assembly industry, in particular to devices for assembling parts by pressing. The purpose of the invention is to improve the quality of the assembly when pressing in parts such as dowels. The device comprises a housing 1 with spring-loaded guide jaws 10 and a carriage 2 movably mounted in the housing 1. The carriage houses the centering rod 4 and the pressing-in punch 5. The centering rod 4 is equipped with a safety device 9 with a rectangular cross section installed in the centering T-slot the rod 4 is movable in a plane perpendicular to its axis. The safety device 9 interacts with the keyway of the shaft 14 and the guide jaws 10. The clamp 12 fixes the shaft and the guide jaws oriented relative to each other. When the carriage 2 is moved, the pressing punch 5 and the receiver with the press-in key are mounted opposite the keyway of the shaft 14 and the key is pressed in. 3 il.

The invention relates to assembly production, in particular to devices for pressing in keys.

The aim of the invention is to improve the quality of the assembly when pressing in parts such as keys by ensuring accurate orientation of the assembled parts.

FIG. 1 shows a device for installing and pressing in a key, a general view; FIG. 2 is a section A-A on (iHr, lj in FIG. 3) section B-B in FIG. I,

The device for assembling parts consists of a housing 1 with a movable carriage 2 placed in it, in which a receiver 3 for keys is installed and a centering rod 4 parallel to each other and a pressing punch 5 with a spring 6, At the end of the centering rod 4 in T- shaped groove 7 on the support hinges 8 A safety device 9 of rectangular section is installed, the width of which is equal to the width of the key groove. On the side of the catcher 9, on the housing 1, there are guide pads 10, spring-loaded with springs 1 I and fixed by a clamp. 12, The working surface of the jaws 10 corresponds to the shape of the catcher.

For driving the orienting rod 4 and the pressing punch 5, the working cylinder 13 is mounted on the housing I.

 A device for assembling parts by pressing works as follows.

The shaft 14, oriented along the keyway and installed in the fixture (not shown), leads to the housing 1, the working cylinder 13, interacts with the orienting rod 4, delivers the safety device 9 | To the shaft 1-, the catcher 9 enters the keyway 1 of the shaft thanks to The possibilities of movement with the help of hinges 8 in the plane, perpendicular to the axis of the centering rod 4, take into account the deviations of the position of the groove of the shaft 14 relative to the ko, the pus 1 and, thus, sets the guide jaws 10 according to the location and size of the keyway. The clamp 12 guides the jaws 10 are fixed in this position. In this case, a key enters the receiver 3, and the cylinder 13 returns the centrifugal rod 4 with the safety gear 9 into the use

running position. The carriage 2 is moved by a cylinder (not shown) and the centering rod 4 is occupied by the pressing punch 5, the working cylinder 13 by means of the pressing punch 5 takes the key from the receiver 3 into the opening between the gripping jaws, which give direction to the key, and press the key into the keyway of the shaft 14 After pressing in, the clamps 12 are retracted from the jaws 10 and the shaft 14 with the key exits the device ,, Then the pressing die 5 is returned to its original position using a spring 6, the carriage 2 is also moved to its original position, while ssovochny sleep 5 with the receiver 3 is disposed under the feeder (not shown) and the centering rod 4 catcher 9 - yuischh opposite guide jaws 10,

The device is ready to assemble the next key connection,

Formula of invention

A device for assembling parts by pressing, comprising a housing installed therein with the possibility of reciprocating movement in a plane, perpendicular to the pressing axis, a carriage with a drive for moving it and parallel to its location. centrifugal punch and press-on punch, equipped with an actuator, as well as means of relative centering of the base part and the carriage with the fixing element in the working position, which is so that, in order to improve the quality of the assembly when pressing in the key type parts, it is equipped with a rectangular cross-section safety device installed at the end of the centering rod with the ability to move in a plane perpendicular to the pressing-in axis, and the means of relative centering of the base part and the carriage are made in the form of guide jaws placed on both sides of the axial pressing with the possibility of reciprocating movement in a plane perpendicular to this axis, and spring-loaded towards it, while the working surface of the jaws is made in the appropriate form of a catcher.
