Description

The invention relates to the automation of metalworking and can be used in robotic systems for manufacturing technological machines, as well as an intermediate storage of parts.

The purpose of the invention is to expand the technological capabilities of the device by using a disk for parts of different diameters without retooling.

FIG. shows the boot device, a longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is a view B in FIG. one; in fig. 4 is a view of B in FIG. one; in fig. 5 is a section of YYD in FIG. 3; in fig. 6 is a section d-d in FIG. four; in fig. 7 — node I in FIG. four.

The loading device consists of a disk 1 mounted with its shaft 2 in the sub-pins 3. The latter are installed in the carriage 4 having V-shaped guides 5. It is also possible to use rectangular or dovetail guides. H1 6 interact with a V-shaped (or, respectively, U-shaped guide, or guide mud, “dovetail, etc.”) supporting surface of the base 7. To the bottom of the carriage 4, the cup 8 is fixed, on which the drive engine 9 (for example, type RD-9 SD). The motor shaft through the coupling 10 is connected with the shaft 2.

On the upper plane of the disk 1 is made of a spiral tray 11 (Fig. 3 and 4) with a helix pitch equal to a. Instead of a spiral tray, sockets can be made that are located but spirals that have a pitch a with some circumferential pitch G.

On the lower plane of the disk 1, there is a spiral groove 12 (FIGS. 5 and 6), interacting with its side surfaces with a roller 13 mounted on the fixed axis of the bracket 14 of the base 7. The spiral of the groove 12 is aligned in direction and pitch with the spiral of the tray 11 .

On the protruding parts x 15 of the lower plane of the disk 1 (Fig. 5 and 6) there are marks 16 with uniform circumferential pitch 1 i.e T const. The marks can be made in the form of teeth or light and dark scratches. Sensor 16 (inductive, pneumatic or optical), mounted on base 7, communicates with marks 16. The sensor is connected to a control system (not shown).

The boot device operates as follows.

The blanks 18 (or parts to be assembled) are loaded into the spiral tray 11, and the disk 1 is rotated by the drive 9. As the disk 1 interacts with the roller 13, it also moves in V-shaped guides. For one revolution of the shaft 2 drive also turning

one turn and at the same time not moving in the direction of the roller 13 one step of the helix a. When rotated by an arbitrary angle tp, this movement is equal to -, ha. Thus, if the gripper arm (not shown) is installed, for example, in the center of tray 11, this mutual position will be permanently maintained when the cassette 1 is rotated due to the consistency of the scars of spirals 11 and 12.

The blanks 18 are installed with some circumferential QiaroM in (pre-set). The step in should be assigned from the condition in n-t, where n 1,2,3 ... The value of n is processed by the control system and monitored by sensor 17. With a sufficiently small step h; the fulfillment of this condition is not difficult (for example, at 5 mm). After taking (or lowering) the regular part 18 from the tray 11, the actuator 9 is turned on and the disk 1 is rotated. t,

After the cassette is rotated on the n pulses emitted by sensor 17, the actuator 9 stops and the manipulator captures (or sets) the next part, etc.

When changing parts, it is necessary to set a new disk rotation pitch 1 by specifying the number and pulses n produced by sensor 17. And since the label pitch is constant, i.e. ; const, then n-i const at any angle of rotation of the spiral. FIG. 3 shows the arrangement of the parts 18 in the tray 11. In this case, at the maximum radius of the helix, the angle corresponding to the pitch of the parts 18 is equal to d, and at the minimum radius. At the same time .. However, applying labels with T const makes it possible to solve the rotation problem exactly by a given step at σ ;, jt const, at r V-ag.
