SU1662842A1 - Gripping device - Google Patents

Abstract

The invention relates to mechanical engineering and can be used to grip parts. The purpose of the invention is to expand the technological capabilities of the device by increasing the capture zone. The gripping device comprises a housing 1, a drive motor consisting of a rotor 2 and a stator 3 placed rotatably in the housing 1. Torsion shafts 4 and 5 are rigidly attached to the rotor 2 and the stator 3, on which gears 6 and 7 are attached to opposite ends, which engage with gear wheels 8 and 9, which are rigidly fixed on the spindle screws 10 and 11. By means of driving screws 10 and 11, nuts 12 and 13 are moved, to which the clamping jaws 14 and 15 are fixed, as well as the locking sleeves 16 and 17. 2 sludge.

Description

The invention relates to mechanical engineering and can be used to grip parts that lie with large deviations from the central axis of the manipulator grip.

The aim of the invention is the expansion of technological capabilities by increasing the area of capture parts.

Figure 1 shows the proposed gripping device, a side view of figure 2 - section aa in figure 1.

The gripping device consists of a housing 1, a drive motor comprising a rotor 2 and a stator 3, rotatably fixed in the housing 1. Torsion shafts 4 and 5 are rigidly attached to the rotor 2 and the stator 3, on which gears 6 and 7 are attached to opposite ends, which engage with gear wheels 8 and 9, which are rigidly fixed on the spindle screws 10 and 11, along which the nuts move 12 and 13 with clamping jaws 14 and 15 placed on them. To fix the clamping jaws 14 and 15 in a horizontal position, fixing sleeves 16 and 17 are placed on the spindle screws 11 and 10.

The gripping device operates as follows.

In the initial state, the clamping jaws 14 and 15 are separated to the edges of the chassis screws 10 and 11, on which the gears 8 and 9 are attached. After turning on the drive motor, its rotor 2 and stator 3 begin to rotate in different directions, driving it through torsions and gears 6-8, 7-9 spindles 10 and 11 Nuts

12 and 13, which are located on these screws, begin to move along the thread towards each other, bringing together the clamping jaws 14 and 15. If the gripping part 18 is to the right of the central axis of the tongue B-B (Fig. 2), the first part 18 touches the clamping the sponge 15, braking at the same time through the screw and gear transmissions the stator 3 of the drive motor, the rotor 2, while continuing to rotate, continues to drive the clamping sponge 14 until it also touches the parts 18.

The release of part 18 is effected by reversing the drive motor.

In the gripping device, the deviation of the center of the part from the central axis of the device can reach the value L, where 2L is the full width of the gripping device.

Claims (1)

Claims of the invention: A gripping device comprising a housing, a driving motor, the stator of which is rotatably mounted in the housing, and clamping jaws connected by means of nuts and drive screws with stator and rotor of the engine, characterized in that, in order to expand technological capabilities by increasing the area of engagement of parts, it equipped with torsion shafts, one of which is rigidly attached to the stator, and the other to the rotor, and gear pairs, one wheel of which is mounted on the stator and the rotor, while others are engaged with them and are mounted on the respective driving screws.
