Description

one

This invention relates to the automation of assembly processes in a number of industries, such as the assembly of products from ferromagnetic parts. a large number of holes mating with fasteners.

The known devices for assembling products, containing a guide made of magnetic material, do not provide sufficient reliability when inserting some parts into the holes of others when assembling the product, and also have low productivity.

The purpose of the invention is to improve the performance and reliability of the device.

For this purpose, the guide device is provided with a magnetizing winding and is made of a material material, the magnetic permeability of which is higher than the magnetic permeability of the base part of the assembled product, for example, a package of magnetic core plates.

The number of guides corresponds to the number of parts supplied to the assembly with the base part of the assembled product.

FIG. 1 shows the proposed device, e.g., W-shaped, which are an integral part of the magnetic system of a number of mass-produced products, for example magnetic actuators,

view; in fig. 2 - the same, longitudinal rdzrez; in fig. 3 shows section A-A in FIG. 2

The assembly device can be made as a unit to a rotor machine of known design (the structure of the rotor machine itself is not shown in the drawings) or it is used independently.

Claims (2)

The device for the assembly (fig.) Contains the upper / middle 2 and lower 3 plates mounted on two columns 4 and 5. Columns 4 a 5 are rigidly fixed in the plate /. Plates 2 t 3 can move along columns # and 5. Ferromagnetic rods 6 (holders) are fixed in the top plate / fixedly mounted with magnetizing winding 7. The medium plate 2 with holes is made | From non-magnetic material 1 and is designed to install and base the assembled product (Sh-shaped magnetic circuit). In the lower plate 5, guides 2 mounted coaxially with the holes of the plate 2, 8, made in the form of ferromagnetic rods and equipped with magnetizing jigs 9, Winding 9, etc., are fixed to the middle plate 2 with a non-magnetic frame 10. Plates 2 and 5 and columns 4 to 5 form a magnetic core. The number and location of the rods 6 (holders) and guides 8 correspond to the location from 5: 1 "I: version in the middle plate 2 and the location of the holes of the assembled product. The products are laterally based on the angled plates //, and on the top — on the clamp 12. In the case of the type of assembled product, the device needs to change only the position of the holders and guides, as well as the basing plate 1L of the assembly unit. with a drive rod of a machine, e.g. a rotor, giving it a certain law of movement within the required stroke. This stroke is mainly determined by the size of the package height of the W-shaped plates of the magnetic circuit and the air gap between the package and the ends of the rivets 14. The sequence of feeding the assembled elements into the device can be any. The windings 7 of the magnetizing coils are connected in parallel to the general P1ItA circuit and are controlled from the automatic switch 15 (Fig. 2). Wraps 9 guides 5 are included in the circuit in a similar way and are controlled by a key 16. If necessary, the columns 4. C 5 are additionally magnetised by windings / 7 located on these columns. The bottom plate is connected with the rotor drive rod by the shank 18. The clamp 12 can be of any shape and can have an electromagnetic, pneumatic and any other drive, in this case the clamp is mounted at the end of the pi 19 that is moved by the solenoid 20. The gripper of the transport rotor simultaneously feeds the rivets 14 to the rods 6. When the axes of the rods 6 coincide with the axes of the rivets 14, the key 15 closes, the gripping of the transport rotor releases the rivets and they are held only by the magnetizing windings 7. The magnetic core plates are fed to the device build another motor rotor or automatic loading device. The solenoid 20 is switched on, which moves tug 19 with the clamp 12 down - a pack of 13 plates is clamped (lb. 3): Then the plate 3 with the guides 8 rises up, the stroke of the plate ensures that the end of the guide 8 goes to the rivet of the rivet 14 - loose contact between ends is allowed. The gap can be several millimeters. At this moment, the key 16 of the windings 9 closes. The magnetizing winding 9 of the guides 8 has a larger number of ampere turns compared to the winding 7 of the upper rods 6 holding the rivets 14. Due to this, the rivets 14 move to the end of the guides 8. And further during the reverse course of the plate 3 down are located in the corresponding holes of the package 13. Since the magnetic permeability of the guides 8 is higher than the magnetic permeability of the package 13 of the magnetic circuit, the rivet is entrained by the magnetic flux of the guide and does not experience the attracting effect package walls 13. Upon completion of the rivets installation process in the holes of the package, the coils are turned off and de-energized, and the clamp 12 is retracted to the upper position, freeing the package, which is fed by known means for further processing. If it is necessary to assemble the screw connections, the magnetic guides are associated with an additional rotational movement. In this case, the guide has an additional function of a magnetic screwdriver. Claim 1. Device for assembling products from ferromagnetic parts, such as magnetic magnetic actuator, containing a guide made of magnetic material, characterized in that, in order to increase reliability and productivity, the guide is provided with a magnetizing winding and is made of a material whose magnetic permeability is higher magnetic permeability of the base part of the assembled product, for example, a package of magnetic core plates. 2. The device according to claim 1, characterized in that the number of guides corresponds to the number of parts supplied to the assembly with the base part of the assembly.
