Internal grinding tool for duplicate gear

Abstract

The invention discloses an internal grinding tool for a duplicate gear. The internal grinding tool comprises a large flange connected with a machine tool, and a first cavity is formed in the middle ofthe large flange. An annular supporting block is arranged at the bottom of the large flange, and an inner diaphragm is arranged on the annular supporting block. An annular fixing groove is formed inthe top of the side wall of the first cavity, and an outer diaphragm is arranged on the annular fixing groove. An ejector rod is arranged between the inner diaphragm and the outer diaphragm, and a second cavity is formed in the middle of the ejector rod. An end face supporting frame is arranged below the inner diaphragm, and an end face supporting plate is arranged in the second cavity. The end face supporting frame and the end face supporting plate are connected through end face supporting rods, and multiple first connecting blocks are annularly arranged on the top face of the inner diaphragm. Multiple locking blocks for fixing the first connecting blocks are arranged on the bottom face of the inner diaphragm. First clamping blocks are fixedly arranged on the first connecting blocks, second connecting blocks are annularly arranged on the top face of the outer diaphragm, and second clamping blocks are fixedly arranged on the second connecting blocks.

Description

technical field [0001] The invention belongs to the technical field of double gear processing equipment, and in particular relates to an internal grinding tool for double gears. Background technique [0002] Duplex gears are widely used in various construction machinery such as gearboxes. In the processing of gears, in order to ensure the radial runout of the duplex gear ring, the inner hole needs to be ground after heat treatment. [0003] In the prior art, only the large gear is used for positioning in the subsequent processing of the double gear, and when the positional relationship between the large gear and the small gear is ensured, a specific position of the large gear is found with the naked eye. However, this positioning method is only visually observed, and the accuracy is not high. After processing, it needs to be inspected to confirm whether the selected tooth groove is correct, which is very cumbersome and time-consuming. Contents of the invention [0004] In...

Problems solved by technology

[0003] In the prior art, only the large gear is used for positioning in the subsequent processing of the double gear, and when the positional relationship between the large gear and the small gear is ensured, a specific position of the large gear is found with the naked eye. The tooth groove is used for positioning, but this positioning method is only observed by the naked eye, and the accuracy is not high. After processing, it needs to be inspected to confirm whether the selected tooth groove is correct, which is very cumbersome and time-consuming.
