Abstract

The invention relates to table rotation mechanisms and can be used to automate the process of machining, assembling, welding in various industries. The purpose of the invention is to simplify the design and increase the effectiveness of torching the table in the extreme position, achieved by providing resistance to the outflow of working fluid from the source cavities of the power cylinders. When air enters the piston cavity of the cylinder 3, its piston through the rod-rod 6, the gear wheel 7 turns the table face. The fluid from the rod end of the cylinder 3 is distilled into the same cavity of cylinder 2. And only at the end of the stroke of the cylinder does it become choked by reducing the flow area between the rod-rod 6 and the hole in the sleeve 11. Then, when the seal 13 enters the hole in the sleeve 11 , the fluid flows only through the channel into the choke. To ensure the independence of the braking magnitude in both directions of table rotation in the housing, an additional channel with a choke is installed, in series with which check valves, oppositely oriented, are installed. 1 hp ff, 4 ill.

FIG. 1 in FIG. 3 - a section through the channel connecting the rod end of the cylinder; in fig. - connection diagram of cylinder rod cavities.

With the housing 1 are connected lva power cylinder. in the form of pneumatic cylinders 2 and 3, the pistons and 5 of which are interconnected by a rod-rod 6 interacting with a gear wheel 7. The wheel 7 is rigidly fixed to the shaft 8, on which the rotary faceplate 9 is installed. The rod-rod 6 is located iHa two bushings 1C and 11, which were buried in the bores of the casing f, and are made ;.

zi ini / ipa, therefore, through it and the damp cavity of cylinder 3, the field / iyx left there is first displaced, and then the liquid is displaced. The rate of liquid displacement through channel 15 was determined by the SGS polo .-- Drossel's opium 16.

Thus, braking is carried out in three stages: the first is the intake of liquid through the annular gap, and the creator is through Kamal and the throttle, the Ptoroll is the displacement of only air through channel 15 and the throttle 16, the third is the replacement of only liquid through channel 15 and the throttle sixteen,

The use of two channels 15 and 18, connecting cylinder rod cavities. and 3 and adjustable chokes 16 and 19 with non-return valves 20, which are threaded towards each other, allow independent control of the braking efficiency c. both directions of table rotation.

Formula inaobr.en.

1. A table turning mechanism containing two power cylinders with seals installed in the housing, the pistons of which are interconnected by a rod-rod interacting with a toothed spike, which is different in order to simplify and increase the braking efficiency of the table in its extreme position beyond the expense of providing resistance to the outflow of working fluid from the rod end of the power cylinders, the rod-bearing portions adjacent to the piston are cylindrical and seals are placed on them, and the cylinder piston cavities are connected to nalom formed body, wherein the set of entered in variable throttle mechanism.

2. Mechanism but clause 1, which differs from the fact that, in order to ensure a non-recordable adjustment of the table brakes in both extreme positions, an additional channel is installed in the housing for installing a lunch n additional adjustable throttle mechanism, while the mechanism is equipped check valves, each of which is installed in series with a corresponding choke -).
