Problems solved by technology

[0002] Since the two raceways of double-row tapered roller bearings (such as railway wagon bearings, second-generation automobile wheel bearings, etc.) form symmetrical conical surfaces, according to the current super-finishing method, it is necessary to super-finish one raceway first, and then turn around and super-finish Another raceway, unable to superfinish both raceways at the same time or step by step
It not only causes repetition and cumbersome processing procedures, affects production efficiency, increases labor intensity of workers, but also seriously affects processing accuracy, which cannot meet the growing quality requirements of bearing manufacturing.

Embodiment Construction

[0012] As shown in the figure: on the connecting plate 19, there are two groups of cylinders. In the first group of cylinders, there are first pressurized cylinders 1 and first jump-in and jump-out cylinders 3 arranged side by side. The first pressing rod 7 is connected on the pressing piston rod 9, and the first knife rest 5 is set on the first jumping piston rod 8 of the first jumping in and out of the cylinder 3, and the first knife rest 5 for fixing the oil stone is set on the first knife rest 5. One oil stone box6.

[0013] In the second group of cylinders, the second jumping in and out cylinder 20 and the second pressurized cylinder 12 arranged side by side are arranged, and the second tool rest 15 is connected on the second pressurized piston rod 17 of the second jumped in and out cylinder 20, A second pressing rod 13 is arranged on the second jumping piston rod 16 of the second pressurizing cylinder 12 , and a second oil stone box 14 for fixing the oil stone is arrange...

Abstract

The invention relates to a grinding tool for a grinding machine tool, in particular to a superfine head of a double-row tapered roller bearing outer shell. According to the technical scheme of the invention, the superfine head of the double-row tapered roller bearing outer shell comprises a connecting plate and two groups of cylinders installed on the connecting plate, and the superfine head is characteristic in that each group of the cylinders is provided with a pressurizing cylinder and a jump-into and jump-out cylinder both of which are parallel arranged, a pressurizing piston rod of the pressurizing cylinder is connected with a compressive rod, and a tool carrier is arranged on a jumping piston rod of the jump-into and jump-out cylinder. A mechanism provided by the technical scheme can simultaneously process two roller paths, thus the positioning error of secondary positioning can be avoided and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a grinding tool for a grinding machine tool, in particular to a super-precision head of a double-row tapered roller bearing jacket. Background technique [0002] Since the two raceways of double-row tapered roller bearings (such as railway wagon bearings, second-generation automobile wheel bearings, etc.) form symmetrical conical surfaces, according to the current super-finishing method, it is necessary to super-finish one raceway first, and then turn around and super-finish The other raceway cannot superfine the two raceways at the same time or step by step. It not only causes repetition and cumbersome processing procedures, affects production efficiency, increases labor intensity of workers, but also seriously affects processing accuracy, which cannot meet the growing quality requirements of bearing manufacturing. Contents of the invention [0003] The purpose of the present invention is to design a double-row tapered roll...
