Abstract

The invention can be used in industrial man-guns for automation and mechanization of technological processes. The purpose of the invention is to expand the technological capabilities by increasing the range of movement of the clamping jaws. For this, the gripper is equipped with a magnetic cylinder with a magnetic coupling between its pistons A and the sliders 2. In the initial state, the clamping jaws 1, mounted on the sliders 2, are rigidly fixed by elastic rings 15 on the case 3 of the power shafts (s). Electro-magnet sliders 2 are rigidly connected to pistons 4 and, attracting coupling 16, press rings 15 from housing 3 and unlatch jaws 1. Supply of working medium under pressure in cylinder housing 3 through nozzles 7 leads to synchronous convergence of jaws 1 due to interactions ubchatyh rails 9 and 10 with the pinion 13 and movement of the guide rod are mounted on two slides in the guide grooves of the housing prevents misalignment of the jaws. 2 yl.

Description

The invention relates to mechanical engineering, in particular to industrial manipulators for mechanization and automation of technological processes in various industries.

The aim of the invention is to reduce the dimensions of the gripper and expand its technological capabilities by increasing the range of movement of the clamping jaws.

Figure 1 shows the proposed gripper manipulator; figure 2 - section aa in figure 1.

The gripper arm contains clamping jaws 1 mounted on sliders 2 installed with the possibility of longitudinal movement on the body 3 of the power cylinder with magnetic coupling between the pistons 4 and the sliders 2. The body 3 has a flange 5 and fitting 6, and from the ends it is closed lids with fittings 7, krischki are attached to the bracket 8. On the sliders 2, gear racks 9 and 10 are rigidly mounted with the possibility of their interaction with gear 11, which is loosely mounted on the axis 12, fixed on the bracket 8. In the guide grooves of the bracket 8 are installed vodka 13, strongly fortified ennye the slides 2. Leads 13 serve to eliminate the sliders 2 rotate about its axis. To induce a magnetic force field of a rigidly connecting piston 4 with sliders 2, coils 14 of direct current electromagnets are installed in the latter. The slides 2 are rigidly fixed on the housing 3 by conical elastic rings 15, compressing the housing 3 and connecting the sliders 2 to the sleeves 16,

The grab of the manipulator works as follows.

The coils 14 are powered from a direct current source (not shown), the magnetic force field rigidly connects the pistons 4 to the sliders 2, and the ends of the sliders 2 pull the sleeves 16 in a magnetic field, which, together with the sliders, interact with their grooves with conical elastic surfaces rings 15 and ozhi,

waving the latter from the housing 3, so that the samm will unlock the slide blocks 2. By applying the working medium (liquid or gas) under pressure into the cavity of the housing 3 through fittings 7 and connecting fitting 6 to the outlet pipe, the pistons 4 are forced to move towards each other. The pistons 4 by the magnetic field move the slide blocks 2 in the same direction. .The convergence of the sliders 2 and the counter-movement of the toothed racks 9 and 10 fixed on them, which interact with the gear 11, leads to the synchronous convergence of the clamping jaws 1. At the same time, the drivers 13 slide towards in the guide grooves of the clamp 8, ensuring the orientation of the clamping jaws. When the supply of the working fluid under pressure through the nozzles 7 is stopped, the approaching of the jaws 1 stops, and when the supply of the coils 14 is disconnected, the sliders 2 are rigidly fixed on the housings 3 by clamping elastic rings 15 as a result of the sleeves 16 leaving the sliders 2 under the action of elastic forces of the rings 15 and interaction their conical surfaces with conical grooves of sliders and couplings. In order to operate, the jaws 1 turn on the power supply to the coils 14 and supply the working fluid under pressure through the fitting 6, and the fittings 7 are connected to the outlet pipe,
