(54) DEVICE FOR ASSEMBLY OF PARTS

one

The invention relates to instrument making, and to the replacement assembly devices, and relates to a device for assembling a thermostat housing with a fixing bar.

A device for assembling parts is known, comprising an installation unit with a self-centering gripper located on an elastic suspension, and a supply unit for a complete part 1.

The disadvantage of the known device is the unreliability of the assembly process, since it does not ensure the orientation of the part supplied to the gripper.

The purpose of the invention is to increase the reliability of the assembly process by increasing the accuracy of the relative orientation of the parts to be completed, as well as to increase productivity.

This goal is achieved by the fact that the device is equipped with an orienting node, made in the form of an abutment and rigidly connected with it by a grip, and the grip is made in the form of two spring-loaded strips located in the additionally made slots of the suspension, with the pliber of the orienting device and the grip axis one n yuskost.ch.

In addition, the grip is equipped with a spherical support element.

with self-centering grip 2 for the complete set of my part 3 (fixing n,: 1-channel). A 13 piece (thermostat housing) 4 is installed in a satellite arrangement located on the turntable 5. In the gripper 2, the fixing plate is fed along a direction 6 with a slide 7 fastened to the slider 8. The protrusion of the latter is fitted with a adjustable stop 9, arranged in such a way that

20, when crawling in motion, steps 8 in the direction of the base part 3, it enters the groove in the housing. thermostat designed to install fixer plate. At the same time, the working surface of the stop is displaced relative to the working surface of the gate (in the direction of their movement) by the size of the groove wall of the component being assembled. The locking bars pre-assembled into the bag are fed to the gate 7 through the chute 10. The self-centering grip contains a suspension 11 mounted for movement in the grooves of a fork 12 mounted on the vertical slider 1. The completed part is placed between two bars 13 and 14 placed in the grooves suspension. The part of the body of the suspension between the grooves forms a supporting element of the grip, made spherical, which facilitates the gardening of the completed part relative to the base part, and the chamfer is made on the surface of the completed part. The groove under the bar 13 is expanded in the direction of the working part of the support element, and the bar itself is pressed against it by a spring-loaded ball 15. In the initial position, the suspension, clamped between the bars 13 and 14 by the completed part, is displaced relative to the nominal position by the spring 16 by some distance greater than the maximum possible This direction of installation of the base part. For orientation — the suspension 11 with the fixing bar clamped relative to the thermostat housing — serves as a projection 17 of the suspension, having an inclined plane designed to interact with the lateral surface of the base part. In addition, the suspension is spring-loaded from below by a spring 18. The device works as follows: The parts 3 assembled into the bag are fed along the chute 10 to the gate 7. When the horizontal slide 8 moves towards the base part, the hook 7 cuts off ONE part 3 from the bag and feeds it to gripping until the stop 9 comes into contact with the end of the protrusion in the groove of the thermostat housing. The slider 8 with the gate and the stop returns to its original position. The kit is clamped onto the part. the supporting element between the spring-loaded bar 13 and the bar 4. The vertical slider 1 with the grip 2 moves upward, while the inclined plane of the protrusion 17 interacts with the surface of the base part 4 and orients the suspension 11 with the clamped part 3 relative to the groove in the body of the base part. Upon further movement of the slide 1 upward, the parts are assembled, after which the latter returns to its original position. Claim 1. Device for assembling parts, comprising an installation unit with a self-centering grip located on an elastic suspension, and a supply unit for a complete set, characterized in that, in order to increase reliability and performance, it is equipped with an orienting unit, made in the form of an emphasis and rigidly associated with him gate, and the grip is made in the form of two spring-loaded strips, located in additionally made in the suspension grooves, and the gate of the orienting device and the grip axis are located in one PL sharpness. 2. The device according to claim 1, characterized in that the gripper is provided with a spherical support element. 3. The device according to claim 1, characterized in that a projection with a bevel is made on the suspension. Sources of information taken into account during the examination 1.
