Description

I

This invention relates to the abrasive machining of crankshafts.

A device for processing crankshafts is known, made in the form of a body with mounted on it with the possibility of rotation on the base of the rollers of the yoke carrying spring-loaded abrasive tools with the drive of their rotation and oscillatory movement flj.

However, the known device does not have sufficient rigidity to obtain the required accuracy and cleanliness of processing, and it does not provide for adjustment of the amplitude of tool oscillations ./.5

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

This goal is achieved by the fact that the collar is made in all three detachable fittings. medium / concentric rings average20

and the inner one of which is provided with gear and through the outer ring is kinematically connected with a driven rotation and oscillatory movement of the tool.

FIG. 1 shows the proposed device, a cross-section; in fig. 2 section A-A of FIG. one; in fig. 3 - section BB of FIG. one; in fig. 4 - slices nke BB in FIG. one.

The device for processing the jaws of the roller shaft consists of a housing 1 with a flap, a sector 2 and a fixing flap bolt 3 with a nut 4 and adjusting rollers 5, which interact with the outer surface of the separable ring 6 and 7. provided with a movable in the radial direction of the yoke 8 and the adjusting screw 9.

The split ring 6 and 7 are hingedly connected with the Y shaft, the opposite end of which is connected to the slide I located in the radial groove of the drive disk 12. The slide 11 has a thread for connection with the screw 13 fixed in the disk 12 from the longitudinal

strap. The disk 12 on the periphery has a screwdriver atsuyus into the cuts, a scientific research institute with a screw 14, is installed on a shaft 15. On the shaft of a 15th bevel gear, the gear 167 is snug in engagement with a bevel gear 17, put on a gear, and the gear 161 is snugly meshed with the bevel gear 17, put on a gear, and the gear 161 is snugly meshed with the bevel gear 17, put on a gear, and the gear 167 is snug in engagement with the bevel gear 17, and the gear is attached to the gear 167, but the gear 167 is snugly hooked with the bevel gear 17, and the gear is attached to the gear 167ko. Gear 19 is firmly fixed on the latter and meshes with gear 20. Gear 20 passes through the through groove of the outer ring (6 and 7) and is meshed with the outer gear crown of the middle split 21 to 22. The middle split ring is equipped with an internal gear crown 23, through which it engages gears with gearing:, 24, and through gears 25-28 communicates movement to endless abrasive belts 29. The gears axes 25-28 are interconnected by levers 30, Tapes 29 are located on pulleys 31, JKOT Siei jKecTKo are fixed to wasp x 32 mouth In the middle part of the rods, the EYA is fitted with rollers 34. The axle x 32 beams fllgSSrteftei have 35 spring loaded plugs, the opposite ends of the rods are made in the inner split ring 36 and 37, one of the forks 35 is not under the same gear. hard. The inner ring 36 and 37 is supplied with a knurled ring gear 38, with which it is located in the connection with the gear 39, which is located in the locking with the gear 4O. On axis 41 of gear wheel 4O, a rigidly wired worm wheel 42 was found to be engaged with a screw 43. Cher v: - yjKs: -s. (Ir. Vzh 43 is installed on the outer ring 6, 7 by means of axis 44, on the end of which is mounted spring loaded 45 with 46G roller periodically interoperable with stop 47. Stop 47, a) 1 | a | W $) 1 h1 in the hinged sector 2 with a view to c. meifiat relative location of the Hg and the inner and outer rings. The device works as follows. .--- .. "..-,.,. ,,.",.,., The hinged bolt 3 is unclipped and the hinged ceKTqp 2 is unlocked. The hinge 6 and her 21 and 22 and the inner 36 and 37 rings open. and after installation on the neck, the OG Kodenchag shaft would collapse all connections in the reverse PF dye. The folding sector 2 is closed and equipped with a folding bolt 3 with a nut 4. The drive of the machine is switched on and the be 7 7 44 end abrasive belts receive HW YoNi with optimal cutting mode. The middle ring 21 and 22. The inner and outer ring receive an oscillatory motion from the input Disk 12. By informing the ribbons of the VZRratnb pskhI uayatelnoe movement along the axis of the neck, you can handle the crankshaft journal When the oscillating movement of the outer ring 6 and 7, the lever 45, in conjunction with the roller 46 with the stop 47, rotates, and the worm wheel 42 of the gear 39 and 40 through the worm to the 43 rd sprocket inner ring. 36 and 37 relative to outdoor 6 and 7 so that the stop zone of endless abrasive belts changes, i.e., it moves along the shaft neck circumference by 360, which ensures uniform polishing over the entire surface of the neck. Rotation of the screw 13 can change the radius of the connecting rod 10, as well as the amplitude of oscillating endless abrasive belts. It is important, if necessary, to carry out a patch not on the entire surface of the neck, but only in a small area, after a beating of the neck of necks, in the case of non-allele 5 hundred ram and crank. koYayo YatoHChe shaft, as well as when polishing Incomplete cylindrical surfaces. The QiHOBpeMeHiroe rotational and oscillatory movement of the abrasive endless belts provides the best cutting conditions and surface cleanliness of the crankshaft journals. After the final polishing operation, it is necessary to turn off the drive, coMigCTHTb the linkage with the horizontal, pa; ht the outer, middle and inner RING and remove the device from the crankshaft shaft journal. formula of invention device.
