Railway conical rolling bearing inner sleeve raceway grinding undercut machining tool and manufacturing method

Abstract

The invention discloses a railway conical rolling bearing inner sleeve raceway grinding undercut machining tool and a manufacturing method, and belongs to the technical field of railway conical rolling bearing inner sleeve raceway grinding undercut machining tool clamping. The device comprises a tool rest and a tool, the tool is arranged in the tool rest, tool pressing bolts are arranged on the left side and the right side of the top of the tool rest, the bottom ends of the tool pressing bolts sequentially penetrate through the tool rest and the tool and extend into the tool, and an adjusting bolt is arranged on the front face of the tool. The rear end of the adjusting bolt penetrates through the tool and makes contact with the surface of the tool rest. The problems that when an existing numerical control machine tool machines a bearing inner sleeve raceway flange grinding undercut, interference is caused by normal clamping of a machining tool of a conventional model, the requirements for the size and angle of the grinding undercut cannot be met, various special tools are needed due to the fact that products are various in variety and not unique in size, the production cost is greatly increased, multiple times of edge grinding clamping and tool setting are needed, and the machining efficiency is high are solved. The working efficiency is greatly influenced, batch product processing cannot be met, and the product quality cannot be fully guaranteed.

Description

technical field [0001] The invention belongs to the technical field of tool clamping for machining the overrun groove of the inner sleeve raceway of a railway tapered rolling bearing, in particular to a tool for machining the overrun groove of the inner sleeve raceway of a railway tapered rolling bearing and a manufacturing method. Background technique [0002] The bearing ring raceway and rib overtravel groove have the functions of oil-flow lubrication and root cleaning, which is convenient for grinding machine processing and flexible rotation of rolling elements. Their shape, angle and size will directly affect the assembly and running state of the bearing. When the machine tool is processing the over-travel groove of the inner raceway rib of the bearing, the normal type of machine tool will interfere with the normal clamping and processing, which cannot meet the size and angle requirements of the over-travel groove. Due to the variety of products, the size is not unique, s...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the problems raised in the above-mentioned background technology, the object of the present invention is to provide a cutting tool and a manufacturing method for machining the overrun groove of the inner sleeve raceway of the railway tapered rolling bearing, which has the advantage of being able to easily process various oil grooves by fine-tuning the clamping angle, and solves the problem of When the existing CNC machine tool is machining the overtravel groove of the bearing inner sleeve raceway, the normal clamping and processing of conventional machined tools will cause interference, which cannot meet the size and angle requirements of the overtravel groove. Therefore, a variety of special tools are required, which will greatly increase the production cost, and require multiple sharpening, clamping, and tool setting, which greatly affects work efficiency, cannot meet the needs of batch product processing, and cannot fully guarantee product quality.
