Equipment for machining inner-hole gear

Abstract

The invention discloses equipment for machining an inner-hole gear. The equipment comprises a base body, wherein the upper surface of the base body is fixedly connected with a condensation box; the right side surface of the condensation box is fixedly connected with a support arm; a clamping slot is formed in the bottom of the support arm; the inner part of the clamping slot is connected with a driving motor in a clamping manner; an output end of the driving motor is fixedly connected with a rotating shaft; one end, away from the driving motor, of the rotating shaft is fixedly connected with atelescopic box; the inner part of the telescopic box is provided with a first connecting rod and a second connecting rod; the first connecting rod and the second connecting rod are arranged in a cross-scissoring form; both of the upper ends of the first connecting rod and the second connecting rod are fixedly connected with guiding blocks; two symmetrical threaded holes are formed in the corresponding symmetrical side surfaces of the telescopic box; and a threaded rod matched with the corresponding threaded hole is formed in each of the threaded hole. The equipment for machining the inner-hole gear has the advantages that the machining speed is high, cutter tools are conveniently replaced and a requirement on machining different diameters of the same gear teeth can be met at the same time.

Description

technical field [0001] The invention relates to the technical field of gear processing equipment, in particular to an inner hole gear processing equipment. Background technique [0002] A gear is a mechanical element with gears on the rim that continuously mesh to transmit motion and power. The application of gears in transmission has appeared very early. At the end of the 19th century, the principle of the generative gear cutting method and special machine tools and cutting tools using this principle appeared one after another. With the development of production, the stability of gear operation has been paid more attention. The steels commonly used for manufacturing gears include quenched and tempered steel, quenched steel, Carburized hardened steel and nitrided steel. The strength of cast steel is slightly lower than that of forged steel, and it is often used in larger gears; gray cast iron has poor mechanical properties and can be used in light-load open gear transmissi...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides an inner-bore gear processing equipment, which has the advantages of fast processing speed, convenient tool replacement and the ability to process the same teeth with different diameters at the same time, and solves the problems of the existing inner-hole gear processing equipment. The processing speed is slow, it is inconvenient to change the tool and cannot meet the problems of processing the same tooth with different diameters at the same time
