Description

The invention relates to machining and can be used for the manufacture of metallographic thin sections of active materials in protective chambers on machines with remote control.

The purpose of the invention is to simplify the design of the machine and its maintenance by placing the mechanism, the reciprocating rotational motion in the housing of the rotary carriage.

On fis. 1 shows a metallographic sectioning machine, a section; in fig. 2 - section A-A in FIG. one.

The machine for processing metallographic thin sections contains a bed 1, on which the spindle device 2 and the slide 3 supporting the slide 3 are mounted. The spindle device 2 contains a disk 5 with abrasive material, 1-part clutch and an electric motor 7.

On the sutsiort 4 and the Novorot carriage 8 is arnirno mounted, carrying a head 9 with 1 clips, and a pivot arm 0 with a mechanism 11 of the head 9 motor clip to the abrasive material of the disk 5, a retainer 12, o-H1, ec 1, which is fixed by the lever 10 on the carriage 8 and a body 13 rigidly connected with it, the gear wheel 14 of which is located coaxially with the head 9 and is kinematically connected with it (for example, by a square).

Above the disk 5 on the bed frame I is a folding cover 15 containing a retainer 16, hormozi1N, py rail 17, located li of the housing 13. The casing is equipped with ria30M 18, the length of which is equal to the stroke length of the reciprocating alternator, carriage 8, and centered on the bed 1 but the cone 19, and in the formation with the inter-conical foot 20, there is a disk 5 with an abrasive material, and the cavity 20 itself connects

0

Nena with a grinding product removal system 21. The groove 18 provides for the reciprocating movement of the head 9 over the abrasive material of the disk 5 and creates a directional movement of air for suction of waste products into the exhaust system 21.

Gearbox 22 with an electric motor is attached to frame 1. heme 23, which, through cri-B01NIN 24, provide reciprocating non-displacement to the sunport 4 and the carriage 8.

The machine works as follows.

From the electric motor 7, the elastic motion b is transmitted to the disk 5. From the electric motor 23, through the gearbox 22 and the crankshaft 24, the reciprocating movement is transmitted to the carriage 8. At the returnable post and the operator's gear box and the carriage 8, the gear 14 of the duct E is driven around on the neo / izichnoy rail 17, locked by a clamp 16, transmitting the reciprocating movement of the head 9. As a result of the rotation of the disk o, the reciprocating movement of the carriage 8 and the reciprocating rotational movement of the holozk.i 9 achieves the required quality quality of grinding, and remove grinding products by sucking air through groove 18 into exhaust system 21 ensures the quality of the lifts and prevents the maintenance of this machine.

If it is necessary to obtain only reciprocating nots101 about the change of de 1-a-or, the treatment is carried out without sticking the rack 16.

The carriage of the carriage 8 and the casing 15 is jointly retracted when the abrasive material of the disc 5 is removed. When the carriage 8 is rotated by releasing the fixer 16, the oemography of the bodices is made. When the lever 10 is turned by releasing the lock 12, the head 9 is removed.
