Description

one

The traverse of a combination machine, for example, a grinding planer with two guide rails, is known.

Moving the planing and grinding calipers along the same guides adversely affects the machining accuracy.

The proposed cross bar differs from the known ones in that it is provided with a third bar serving as a common guide for both supports, and each of said two bars serves as a second guide for them. In addition, the common guide bar is made with work surfaces that are different for the caliper.

FIG. 1 dan proposed traverse with planing and grinding calipers located on it, front view; in fig. 2 - traverse with the lower slide of the grinding caliper, section; in fig. 3 - traverse with the lower slide of the planing caliper, section.

Planing grinding machine has two columns 1 and traverse 2, on which there are two calipers: planing and grinding. A planing caliper consists of a lower slide 3, a slide, an upper slide 4 and a tool holder 5, a grinding slide from a lower slide 6, an upper slide 7, and a grinding wheel spindle 8.

The guide surface 9 (Fig. 2) is on the back side of the guide

bolts 10, which is bolted on top of the traverse. The remaining guide surfaces 11-13 are located on the guide bar 14, which is fixed on the cross bar from below. Lateral guide surfaces

9 and 12 are moved along the roller guide elements 15, which are fixed to the slide 6 of the caliper. In the vertical direction, the grinding caliper by the bridge 16 attached to the lower sled rests on the guide surface 11. The rear bar 17, which is rigidly connected to the lower slide 6 of the caliper, prevents the tilting of the grinding caliper forward through the guide surface 13.

The lateral movement of the grinding caliper is carried out through a rotating drive spindle 18, which engages with nuts 19 fixed on the lower slide 6. The guide surfaces 20-22 (Fig. 3) are on the T-shaped support, and tilting forward is prevented a strap 23. The bottom slide 3 at the bottom rests on the guide surfaces 24 and

25, made in the form of a dovetail.

In the vertical direction, the support of the slide 3 is carried out by means of a bridge 26 fixed on them through wedge strips 27 and 28 onto guide surfaces 22 and 29,

Side drive incisor caliper wasp. It is realized through the drive spindle 30. The collar shaft 31 is designed for vertical adjustment of the upper slide 4 of the tool carrier. The drive spindles 30 and 18 of the planer and grinding calipers are located, as necessary, between their guides near the line of action of the resultant friction force.
