Description

The invention relates to a machine tool industry, in particular to heavy multi-purpose mill.

The purpose of the invention is to improve the design of the process of improving the manufacturability of the manufacture of rolling bearings and by compensating for the error in the manufacture of rolling poles.

PIA.

FIG. 1 shows a multi-purpose machine general view; in fig. 2 - the same, side view; in fig. 3 a section A - A in FIG. 2; in fig. 4 section) B in FIG. 3; in fig. 5 shows a section B according to FIG. 2; in fig. 6 - section GG on

f.I1. one.

The multi-purpose machine consists of a slide 1, which is installed with the possibility of returning post-movement movement of the rack 2. The tool magazine of the chain type WASTE from the base 3, body 4, mounted on the supporting bracket 5. The east, granspi tera 6 consists of links 7 its capacity is 80 instruments. Magazine drive - a worm gearbox 8 with an electric motor 9 and a drive sprocket 10.

The magazine is located vertically along the rack 2 and is connected with it in the upper part by the bracket 11, and in the lower part by the connecting bar 12. The bracket 11 and the bar 12 are made with elements of compliance that are flat springs with grooves made in vertical planes. x t and n, which make it possible for them to unite in a vertical plane under the action of the load from the weight of the magazine, while still maintaining the h) ei o hard sign of the horizontal plane when moving

To eliminate possible distortions during the movement of the magazine in the housing 4, two pairs of rollers are also installed, mounted also on self-spherical roller bearings 19 rotating on their eccentric axes x 20 and resting on the lateral base surfaces of the rectangular guide 18.

The magazine is aligned with the stand in the vertical plane by adjusting the eccentrics 14, in the horizontal plane by adjusting the eccentrics 20 and adjusting the compensator 21.

The device works as follows.

0 When the rack 2 moves along the slide 1, the magazine associated with it by the upper bracket 11 and the lower bearing bracket 5 with the bar 12 is moved along the guide 18 on the rolling bearings. In this case, the thrust force of movement of the magazine is about 10% of its weight. Due to the compliance, the brace 11 and the plank 12 are deformed under load at a height of 10 square meters; by the weight of the shop and practically the store develops with the S race and approximately 90% of its weight is received by the rolling support. A possible tilting and unwrapping moment on the rack arises only from the tractive effort of the store as it moves, which can be practically neglected. Blockage

, and the turn of the rack is practically excluded. When the magazine is moved along the guide, all four rollers work with the same load due to the presence of the rocker arm 13, | ;;;; turned round around the eccentric axis 4.
