SU16545A1 - Modifying a vertical machine for lapping parts - Google Patents

Description

 Patent No. 16640 describes a vertical machine for lapping parts, a KOTOpdro spindle from the crank mechanisms communicating simultaneously alternating rotation in both directions and returning an 7-translational motion.

In the proposed modified machine, for communicating with the spindle / with the reciprocating part attached to it for lending work, instead of a crank gear, a spike with several cams acting on the spindle associated with the spindle is used.

In the schematic drawing of FIG. 1 depicts the type of the proposed machine side; FIG. 2 is a front view of it; FIG. 3 - a crooked 1/1 transmission from the drive shaft to the spindle. The horizontal shaft 2 of the bed 21 is fitted with a bevel gear 3, a transmission pulley 1 and a washer 14 equipped with: 1 a few fists (Fig. 1 and 2). The bevel gear 3 is engaged with a bevel gear 4, mounted on a vertical shaft 5 terminating at the bottom with a crank gear 6-39-7 connected to post 9 (Fig. 1 and 3), which in turn is coupled with the gear 13 mounted on the spindle 11, having a number of teeth equal to the number of teeth of the half-gear 9. The spindle 13 with the spring 16 mounted on it is engaged by means of a coupling 17 with another spindle 15, which at its upper end carries a roller 8 which is loosely fixed in it, resting on the washer 14 (Fig. I 2).

The part to be lapped is mounted on the work table 27, and the caliper 31 is guided to another part to be ground, mounted in the chuck 12 of the spindle 13. The pulley 1 driven in rotation is communicated by means of bevel gears 3-4, crank T-gears 6-39-7 and gear 21 alternately The rotational movement of the spindle 13, and through the fist puck 14 and the roller 8, the spindle 13 is simultaneously communicated in reciprocating motion. This simultaneous rotational and translational movement is done by grinding the parts, and the spring 16 is used to press the upper part onto the lower part.

For carrying out at the beginning of lapping of the buffer action, sleep "lever 29" 30 is provided, which the juapHHpHO is connected to the work table 27 (Fig. 1-2).

Movement of the caliper is achieved by the enemy of the screw 32, which is associated with the gear 35, which in turn is engaged with the rack 23, and through the clamping bolt 34, the caliper is fixed at the appropriate height.

The subject of the patent.

Modification of the vertical machine for lapping the parts described in patent No. 16640, characterized in that instead of a crank gear, used for communication by the spindle 13 of reciprocating movements-applied on the end of the horizontal drive shaft 2 washer 14 with several fists, acting on the roller 15 associated with the spindle 13, pressed spring 16.
