Circular locus crowned tooth forming grinding swing device

Abstract

The invention belongs to the technical field of crowned tooth machining equipment, and provides a circular locus crowned tooth forming grinding swing device. The circular locus crowned tooth forming grinding swing device comprises a rocker arm which is provided with a grinding head supporting plate in a sliding mode. The rocker arm is fixedly connected with a screw rod nut. A screw rod in threaded connection with the screw rod nut is installed in the grinding head supporting plate in a rotating mode. A cover plate, an index dial and a hand wheel which is in key connection with the top end of the screw rod are sequentially arranged on the top face of the grinding head supporting plate. A grinding head motor and a grinding head fixed base used for installing a modification grinding wheel are installed at the two sides of the grinding head supporting plate correspondingly. A hinged support block is embedded in the top end of the rocker arm. A machine body is provided with two center bases which are correspondingly arranged, and centers abutting against the hinged support block are installed in the center bases. A hinged support is installed on the bottom face of the rocker arm. A limiting plate with an arc sliding rail is hinged to the hinged support, and the hinged support is connected with a hydraulic oil cylinder. By means of the circular locus crowned tooth forming grinding swing device, modification machining of crowned teeth can be achieved conveniently, and machining precision of the crowned teeth is improved; and the circular locus crowned tooth forming grinding swing device can be suitable for flexible adjustment machining of the crowned teeth of different specifications, and universality is high.

Description

technical field [0001] The invention relates to the technical field of drum-shaped tooth processing equipment, in particular to a circular track drum-shaped tooth forming grinding and swinging device. Background technique [0002] When the tooth is a straight line in the indexing circle section, it is called a straight tooth, and when it is a curved tooth in the indexing circle section, it is called a drum-shaped tooth. The drum-shaped tooth is modified along the tooth length direction to improve Due to the radial, angular and axial errors caused by installation errors, it has the advantages of strong bearing capacity, large angular displacement compensation and high transmission efficiency. In addition, the drum-shaped tooth surface improves the contact conditions of the inner and outer teeth, avoiding Under the condition of angular displacement, the edge of the straight tooth end is squeezed and the disadvantages of stress concentration are improved. At the same time, the ...

Problems solved by technology

[0003] In the prior art, milling cutters are often used to process drum-shaped teeth, but the gears cannot be milled after heat treatment, and the processing accuracy of drum-shaped teeth is high, and positioning is difficult, so milling cutter processing cannot meet the high-precision machining quality of drum-shaped teeth It is impossible to realize the flexible adjustment and processing of drum-shaped teeth with different specifications and shapes.
