Description

Adaptation To a turning, grinding or similar machine for superfinishing of crankshaft necks

It was filed on May 27, 1941, in the People's Commissariat of Aviation for f 8512 (314021) Published on January 31, 1944

For machining of trunnions on various machines, tools equipped with a composite collar, fitted on a trunnion and carrying a tool, were already offered, but these devices do not allow machining of trunnions, naimer, crankshaft necks by the superfinish method.

The present invention aims to fill the gap, felt in the specified area of processing crankshaft necks your tool, mounted on a composite collar, worn on the treated | M1 neck. The fixture has that distinctive feature that the clamp with the end of its lever is pivotally connected to the end of the shagun, which is pivotally attached with the second end to the machine's suport, in order to follow the tool behind the crank shaft neck during its processing.

In FIG. 1 is a side view of an exemplary form of the extra large tool according to the invention, and FIG. 2 is a longitudinal area according to

FIG. one..

Processed cheek 1 crankshaft mounted in the centers

turning or grinding machine and covered by a yoke consisting of two 2-3 halves, connected on the one hand by a hinge 4, and on the other hand - by a bolt 9. A lever 5 half 3 of a yoke by a connecting rod 6 is attached to the hinge 7 of the suporta

gaggle

In the case of superfinition, the crankshaft crankshaft crankshaft crankshaft crankshaft and lever 5 are fixed. When superfinishing the connecting rod necks, the lever 5 and the connecting rod 6 perform oscillatory movements, moving the yoke 2-3 with the tool and following aa with the movement of the connecting rod crank of the rotating crankshaft

shaft.

Three rollers 8 roll over the shaft neck 1. One of the rollers 8 is pressed to the shaft neck by adjusting (MY spring 10. In the upper half of the 2 clamp there is a viewing window 11 to be able to observe a repulse with a M10 surface during processing (without removing the device from the neck) The abrasive bars 12 are secured in the holder 13.

Reciprocating movement of abrasive beads 12 along

sheiknall is created; . measures by an electric motor 14, .tiina used in angular electric screwdrivers (produced by Kharkiv labor center IM Dzerzhinsky). Val. 15, an electric motor is provided with an eccentric 16, inserting the recess into the corresponding recess of the holder 13, which moves along the guides 17, which is provided with the sleeve 18, radially inserted into the hole of the BELOVINE 2 Clamp. The pressure of the NT bars 12 is created by a calibrated spring 19. The lever 20 serves to quickly remove the abrasive bars 12 from the shaft neck 1 being machined. Lubricating cooling fluid is led to the bars using a clean tube; not shown in the drawing .:

:; The subject of the search

The adaptation to a lathe, grinding and similar machine for superfinishing of chucks of a shaft of a shaft using a composite yarn that wears a bearing and guides, and a self-guided accessory movement of the holder with abrasive bars, which is pleasant to us. -3 is hingedly connected to the end of the connecting rod 6, the second of which is hinged to the support of the machine, in order to check the tool behind the connecting rod neck during its processing.
