Description

one

The invention is applied to machine building, in particular, to a machine tool cue, and is intended for transporting several large blanks simultaneously from the accumulator along the axis of the automatic line to the treatment zones and installing them into the fixture along the clamping elements.

The purpose of the invention is to increase the productivity and reliability of transportation at a rate of movement of the transport system.

FIG. 1 shows the device, a general view | in fig. 2 is a view A of FIG. one; in fig. 3 is a section b-B in FIG. 2; FIG. 4 is a section B-B in FIG. 2

An auto operator comprises a trolley 1 moving along a base. On the trolley 1, with the help of the rollers 2, the frame 3 is fixed, moving vertically (the drive is not shown). On frame 3, two pairs of carriages 4 and 5 are placed, the gripping mechanisms of which are made in the form of brackets 6 connected at the ends with screws 7 by two strips 8 on both sides of the grip of the workpiece. On one bar there are fixed stops 9, which are set in the same plane, two stops on each transported part 10. Spring-loaded are fixed on the other bar

stops 11, one for each workpiece, approximately in the center of the installed part 10.

On one of the carriages of each pair, the actuator 12 of the screw 13 is fixed, with which the carriages 4 and 5 are moved. The screw 13 has a right and left thread and has a fork 14 with another element, which includes two springs 1.5 placed on the rod 16 mounted on the frame 3. On the fork 14 there is a spike 17, and on the trolley 1 a prism 18 is fixed coaxially with the spike 17 and spring-loaded stops 19, one for each) workpiece. The workpiece 10. (Fig. 1) is depicted at the time of its installation on the mounting element 20 in the fixture 21.

The device works as follows.

The cart 1 moves along the base to the drive (not shown) and, having reached the blanks, stops. The frame 3 is lowered over the rolling pins 2 with 1202800, 2

by the drive power (not shown) to the height providing the gripping of the workpieces by the gripper mechanisms, made in the form of strips 8, fixed on the ends of the brackets 6. The carriages 4 and 5, divorced in the initial position by the size providing the gripping of the blanks 0, begin to come closer along the screw 13, driven in rotation

10 by a drive 12. When this drive 12, mounted on one of the carriages, moves with it along the spline knuckle of the screw 13, due to which it is possible to simultaneously transmit the rotational movement of the screw 13 and the translational movement of the drive 12 itself.

In the case of a displacement axis, A wok 10 with respect to the auto-axis axis of the carriage, located on one side of the blanks, will reach them earlier than the carriages located, on the other side. Full capture of the workpiece will occur due to axial

25 moving the screw 13 and the fork 14 and compressing one of the springs 15, depending on which way the axis of the screen is displaced from the auto-operator axis. In this case, the workpieces are relatively rigid stops 9 located on one of the strips 8, W pressing them with the help of spring-loaded stops 11 located on the other bar, the gripping is carried out along the axis of the blanks 10. When lifting the frame 3 with the blanks 10 upwards, the blanks are removed and the square 4 and 5 are drawn onto the axis of the auto-operator using studs 17 and prisms 18.

When advancing the spike 17 along the groove of the prism 18, the stops 19, mounted on the carriage I, rest against the workpieces 10 and press them against the strips 8. The workpieces oriented to the rigid stops 9 and the axes of the operator, and pressed by the spring-loaded stops — r-iH P and vertical stops 19 , acquire higher accuracy of orientation relative to the axis of the auto-operator and the possibility of transporting parts with increased speed due to their more reliable fixation in the transport device.

In the position of installation of the blanks 10 in the fixture 2 of the machine frame 3

55 with carriages 4 and 5 and the blanks are lowered, and the latter are based on the mounting elements 20 1 of the fixture 2. In this case,

In addition to shifting the axis of symmetry of the mounting elements 20 relative to the axis of symmetry of the auto-operator, the carriages with blanks are reoriented relative to the axis of the mounting elements 20 due to axial movement of the screw 13 by means of an elastic element, thus achieving the accuracy of mounting the blanks in the device 21

202800A

In the case when the design of the blanks does not allow them to be based on the mounting elements 20, the accuracy of orientation of the blank in the tool 5 is achieved using the type 17 located on the fork 14 and a prism similar to the prism 18 installed in the fixture itself at the appropriate level (not 10 shown).
