Abstract

The invention relates to mechanical engineering and allows the expansion of technological capabilities due to the possibility of simultaneously installing a large number of studs of various sizes. The studs from the vibrating hopper are fed to the distribution mechanism and the channels of its turntable are sequentially filled. The disk is then rotated so that its channels are placed coaxially with the outgoing channels and channels in the lower fixed disk into which compressed air is supplied. Due to this, the studs are moved along flexible tubes to the receiving device, and from there to the carriage cartridges. Next, the carriage feeds a set of studs under the head, where they are gripped by the cartridges and installed in the base part. 4 il.

Description

The invention relates to process equipment and can be used in mechanical engineering.

The aim of the invention is the expansion of technological capabilities due to the possibility of simultaneous installation of a large number of studs of various sizes.

FIG. 1 shows an automaton, obsh, iy kind; in fig. 2 - the same, top view; in fig. 3 shows section A-A in FIG. 2; in fig. 4 shows a section BB in FIG. 2

The machine for wrapping the studs comprises a frame 1, a sliding stop 2, an actuator in the form of a head 3 with cartridges 4, a vibrobunker 5 for studs with a tray in the form of a flexible tube 6, a distribution mechanism 7, a receiving device 8 and a carriage reloading mechanism in the form of a carriage 9 s the drive 10 and the collet chuck 11. The distribution mechanism - base 7 is made in the form of fixed plates 12 and 13, between which is placed a rotary disk 14 with channels 15, the number of which corresponds to the number of installed blades. In the top plate 12 are made

exhaust ducts 16 connected by flexible tubes 17 with fixture 8. Opposite ducts 16 in the bottom plate 13 also ducts 18 are connected to a source of compressed air. The receiving device 8 is made in the form of a vertical movement from the actuator 19 of the plate 20 with channels 21 into which the tubes 17 are inserted. In each channel 21 there is a double-arm lever 22 interacting with One arm with the sensor 23.

The machine works as follows.

The studs in the oriented position along the tube 6 are fed into the mechanism 7 and are successively placed in the channels 15 of the disk 14 as it turns. After filling all the channels 15, the disk 14 is rotated so that the channels 15 are coaxial with the channels 16 and 18. The channels 18 are supplied with compressed air and the studs through the tubes 17 fall into the channels 21 of the device 8, and from them into the cartridges 11. In this case the studs interact with levers 22, which give a signal to the control system of the machine about the presence of a pin in accordance with (L

chuck 11. Then the chuck 11 locks the studs, the tool 8 rises, and the carriage 9 moves under the head 3. Then the chucks 4 get rotated, rolled over the studs and lift them up. The carriage 9 returns under the tool 8, and under the head 3, the base part 24 is fed, into which all the studs are wrapped simultaneously.
