Description

The invention relates to mechanical engineering and can be used in the foundry industry, in particular as equipment for the processing of cast parts. five

The purpose of the invention is to increase productivity and improve processing quality.

FIG. 1 shows the installation, the cross-section; in fig. 20

Section A-A in FIG. 1} in fig. · 3 section bb in fig. 2

The installation for finishing machining of cast parts, predominantly the steering case, contains base 15 with the bottom plate 2.

On the bottom plate 2 there is a mechanism 3 for feeding parts with satellites 4.

The installation contains a movable. 20-that 5, moving along the vertical guides 6, and the processing mechanism. The machining mechanism is a mandrel 7, into which the cutting elements 8 are elastically inserted.

l

The cutting elements 8 provided with located in the upper 9 and lower 10. the reference planes of the balls 11.

The balls 11 interact respectively with the movable plate 5 and the base of the mandrel 7. The side planes 12 of the cutting elements 8 are interconnected by elastic plates 13. The mandrels 7 themselves with the cutting elements 8 $ 5

placed in adjustable brackets 14 with the ability to move in a horizontal plane in two coordinates ’natach.

In the lower plate 2 is made of a longitudinal groove 15, provided with a latch 16 from the transverse movement of the satellite 4.

In the places of fastening the bottom plate 2 to the base 1, the installation grooves 17 are made.

In the drawings, the notation:

18-machined casting; 19 and 20 - clamp.

The installation works as follows. ·

The workpiece 18 is placed in the cradle 19 and is fed by the feed mechanism 3 to the treatment area (Fig. '1), where the part is fixed by the clip 20.

After fixing the casting to be processed 18. The movable plate 5 begins to fall along with the cutting elements 8, which are pre-set (oriented) relative to the casting profile being processed. Cutting elements 8 determine the location of the casting 18 with their first tooth and if it (the first. Tooth) enters the "body" - or the gulf is too thick - then the tool moves away with simultaneous rotation around the axis of the upper ball 11, this is ensured by a small contact area balls 11 with the surfaces of the plate 5 and the base of the mandrel 7.

Thus, the optimal cutting mode and the cutting tool seem to run around the casting at the machining site with simultaneous cutting of the bay, and the right choice of elastic elements and their adjustment allows to achieve the necessary depth of penetration of the tooth into the bay to be removed.

Having reached its lower position, the movable plate 5 immediately begins to move backwards, while the teeth of the cutting elements 8 with its back part smooths out “licking” those irregularities - the risks that have been obtained during the downward movement, thereby achieving a higher quality surface treatment. After the movable plate has taken its initial position, the part is unclamped and the part is fed by the feed mechanism 3 to the next machining position.
