Abstract

Use: for automated reception of parts from transport storage devices and their installation in clamping fixtures of automatic lines and aggregate machines with simultaneous orientation. SUMMARY OF THE INVENTION: The orienting device comprises a housing on which a head is fixed for gripping parts 2 and a fixing probe 8 with a spring 9. A moving plate 11 is mounted on the head for gripping parts, mounted rotatably with respect to the axis of the head from the drive, the piston stroke of which is equal to the step L between orientable holes. On the plate 11, a probe is fixed with a spring, the axis of which is offset relative to the probe-clamp 8 by an amount multiple to half the pitch L of the oriented holes of the part 16. The probe and probe are equipped with sensors for controlling their position, 4 Il.

Description

The invention relates to a machine tool industry and can be applied to the automated reception of parts from transport-storage devices and their installation in the fixtures of automatic lines and aggregate machines with simultaneous orientation of the part.

The orienting device is intended for mounting parts such as hubs, drums, gears, as well as parts having an outer contour of any configuration oriented along openings located on concentric circumferences.

An auto-operator is known, comprising a housing, a gripping movement mechanism made in the form of levers, shernirs mounted in a holder, an orientation mechanism having a gear wheel mounted for rotation of the vertical axis, and a spring-loaded probe, an emphasis located on the housing and a clamp fixed on the gripper, at the same time, the probe of the orientation mechanism is also located out of the catch, and in the six of this mechanism, freely mounted on the catch holder, the socket is coaxial with the probe.

Known auto-operator prednaznz1n for installation of parts of a certain shape, requiring orientation on the conveyor or chute in the longitudinal direction.

The head plate for gripping parts, coaxially with which, in the receiving area of the auto-operator, is installed a rotary table with a plate, located on the base of the stop and mounted on the movable plate loziteli and spring-loaded probes.

The closest in technical essence to the device claimed is, as a prototype, the manipulator head, which is selected as a prototype of the gripper, is equipped with a stationary body, a gripping head with a spring-loaded probe, mounted with the possibility of reciprocating and rotating relative to its longitudinal axis , and a sensor probe position sensor.

A disadvantage of the known technical solution is its low productivity.

The aim of the invention is to increase productivity.

To achieve this goal, an orienting device containing a stationary body, a gripping head with a spring-loaded probe, mounted with the possibility of reciprocating movement and rotation relative to its longitudinal axis, and a sensor controlling the probe position, is equipped with a spring-loaded probe-clamp installed on the housing with offset relative to the probe and the sensor for monitoring the position of the probe clamp.

In the proposed technical solution, the distinctive features allow an increase in the productivity of the device due to the fact that the displacement of the clamping clamp relative to the catcher probe reduces the time for the orientation of the part and thereby improves the performance of the device.

FIG. 1 shows an orienting device in section (general view); figure 2 is a plan view; on fig.Z - section aa in figure 2; Fig. 4 shows the workpiece (the dotted lines show the possible positions of the orientable hole relative to the clamp-retainer).

The device comprises a housing 1, on which are fixed: a head for gripping parts, including a drive 2, on the rod 3 of which a wedge copier 4 is fixed, levers 5 with stops 6, 7; and a stylus-latch 8 with a spring 9. A movable plate 11 is mounted on the head to grip the parts with the aid of glass 10. The head 11 is mounted for rotation about the axis from the actuator 12, the piston stroke of which is equal to the step L between the holes. On the plate 11 is fixed probe 10 with a spring 14, the axis of which is offset relative to the axis of the probe clamp 8 by an amount multiple to half the step L of the oriented holes 15 of the part

16. The stylus latch 8 and the stylus 13 are equipped with sensors controlling their position, respectively 17 and 18. The orienting device is fixed on the rod 19 of the manipulator.

0 Orientation device works as follows

The device fits the part, the part is oriented, the grip, transfer and installation of the part into the metal5 fixture of a cutting automatic machine or automatic line. To grip the part 16, the rod 3, together with the wedge copier 4, is lowered and, acting on the stops 6, radips the arms 5, which grip the part 16, while

0 the part must be oriented relative to one of the openings 15. If the part is oriented correctly, then the clamp-clamp 8 immediately falls into the oriented hole 20 and the sensor control 17

5 will not work. If the part is oriented incorrectly and the probe fixer 8 is placed in the body of the part 16, the control sensor 17 is triggered, which gives the command to turn on the drive 12 of the movable plate 11. The plate is rotated together with the probe 13 until the latter goes into one of the holes 15 Details 16. Next, the plate 11 continues to rotate with the part

5 16 relative to the head until the probe-clamp 8 falls into the orientable hole 20 (see Fig. 4).

When the orientable hole is in position 20, the orientation of the part

0 occurs when the movable plate 11 moves to its final position. When the oriented hole is in position 20, the orientation of the part occurs when the movable plate moves from the final position with the part until it coincides with the axis 20, the offset of the axis of the retainer 8 relative to the axis of the catcher 13 provides bridges the catcher probe, if the part is oriented incorrectly, between two adjacent holes, which makes it possible to reduce the drive stroke, thereby reducing the auxiliary time for installation and orientation of the part, To increase the durability of the operation of the device.
