Equipment for processing tooth surface of gear

Abstract

The invention provides equipment for processing a tooth surface of a gear. The equipment mainly comprises a machine base, a large stand column arranged on the machine base, a working turntable for clamping a workpiece, a small stand column which is connected with the working turntable and provided with a tip, and a sliding plate frame which is arranged on the large stand column, capable of movingup and down along a guide rail of the large stand column and used for installing a milling cutter; a screw rod mechanism capable of adjusting a position between the large stand column and the small stand column is transversely arranged between the upper end of the large stand column and the upper end of the small stand column; the large stand column is fixed on the machine base; the sliding plateframe consists of a sliding plate capable of sliding up and down on the large guide rail, and a milling cutter frame fixed on the sliding plate; the working turntable is arranged on a transverse guide rail on the machine base in the north and capable of moving left and right; the lower part of the working turntable is connected with a lower screw rod with a servo motor; and the tip capable of moving up and down on a vertical small guide rail of the small stand column is arranged on the small stand column connected with the working turntable. The equipment for processing the tooth surface of the gear has the characteristics of meeting the requirement of the processing precision of the tooth surface of the gear by test and control adjustment, along with simple structure and convenience for use and installation.

Description

technical field [0001] The invention relates to a processing equipment specially for processing gear tooth surfaces, including gear hobbing machines, gear grinding machines and other equipment, belonging to mechanical processing equipment. Background technique [0002] In the prior art, equipment used for machining gear tooth surfaces mainly includes gear hobbing machines, gear grinding machines, and the like. These devices are mainly composed of a machine base, a large column, a small column, a working turntable specially used for clamping workpieces, and a slide frame installed on the large column for clamping grinding and milling tools. The processed workpiece is placed on the working turntable, and the top connected with the small column is crimped on the working turntable and fixed. When working, the skateboard frame moves up and down along the vertical guide rail on the large column, so that the skateboard frame is fixed. The grinding and milling tool realizes the upp...

AI Technical Summary

Problems solved by technology

The gear tooth surface processing equipment composed of the above structure, its large column and small column are installed on the machine base, and the upper ends are suspended in the air. When processing gears with low height, the rigidity of the large and small columns can basically ensure that the workpiece is processed up and down. The diameter of the end is consistent; but when processing a gear with a large height, in view of the rigidity of the large and small columns, when the milling tool is processing the workpiece, the difference in the upper and lower positions will produce different lateral forces between the large and small columns, resulting in large and small Due to the difference in the stability of the column, it is difficult to ensure the consistent diameter of the processed gear tooth surface, resulting in different taper of the processed tooth surface
