Driven box of numerical control bevel gear checking machine

Abstract

The invention discloses a driven box of a numerical control bevel gear checking machine and belongs to the technical field of numerical control bevel gear checking machines. The driven box comprises a base, two mutually-parallel slide rails are arranged on the base and are provided with a box body, capable of performing relative slip, in a matching way, the bottom of the box body is provided with a lead screw assembly in which a lead screw parallel to the slide rails is arranged in the matching way, the lead screw is connected onto a step motor, the box body is internally provided with a driven main shaft of which the two ends penetrate out of the box body and form motive seal with the box body, a braking wheel is sleeved on the driven main shaft and is provided with a braking sleeve in the matching way, the braking sleeve is connected to a control rod shaft, and the control rod shaft penetrates out of the box body and is connected with a handle seat connected with a handle. By using a coloring method, the driven box of the numerical control bevel gear checking machine can be used for performing simulating check on contact precision, tooth flank clearance, installing distance, noise, operation stability and the like of a bevel gear with axes at right angles and a quasi-double-surface gear through short cycle operation in a driven wheel braking load state.

Description

technical field [0001] The invention relates to a numerical control bevel gear inspection machine, in particular to a driven box of the numerical control bevel gear inspection machine. Background technique [0002] The bevel gear motion quality inspection machine tool in the prior art mainly includes a bed part, a guide rail, a driving box part, a driven box part, a loading device, and an electrical control part in its structure; The detected driving bevel gear in the main shaft hole; the driven box part is equipped with a driven main shaft, and the driven bevel gear is detected in the driven main shaft hole. When testing the bevel gear pair, the above-mentioned driving box part and driven box part need to move on the guide rail of the bed part. [0003] In the prior art, there are two ways to move the guide rails of the active box part and the driven box part on the bed part: 1, manual screw nut; 2, hydraulic cylinder to promote. The main shaft of the active box is driven...
