Toolless Gear Tooth Surface Finishing Device

Abstract

The invention discloses a gear tooth surface finishing device with no tool, which comprises an uniaxial numerical control lathe and a bracket, wherein the uniaxial numerical control lathe is provided with a headstock finial, a tailstock finial, and a heart-shaped clamp driven by a headstock main shaft; the bracket is mounted on a tool rest and is driven to move to and fro by the uniaxial numerical control lathe; a bracket fixed finial is arranged at one end of the bracket; a bracket movable finial is arranged at the other end of the bracket; a mandrel is supported and positioned between the bracket fixed finial and the bracket movable finial; and the axial direction of the mandrel is parallel to that of the headstock main shaft. During use, a driving gear is mounted on the headstock finial and the tailstock finial, and is driven to rotate through the heart-shaped clamp; a driven gear is mounted on the mandrel, and is driven by the driving gear; as the pair of gears roll relatively to generate mutual rolling, the driven gear moves to and fro with the bracket to be extruded and rubbed against the end surface of the driving gear mutually, the purpose of finishing the tooth surface is achieved; one pair of gears can be processed at a time, so that the efficiency is improved about twice; and the cutting process is avoided, so that tooth shape cannot be damaged, the tooth shape precision cannot be reduced, and the cost is very low.

Description

technical field [0001] The invention relates to gear tooth surface processing equipment, in particular to a gear tooth surface finishing device without tools. Background technique [0002] During the production process of the gear, there will be some bump marks and small burrs on the tooth surface more or less. If the tooth surface is not smoothed to remove the bump marks and small burrs, the gear will make a lot of noise during operation. [0003] Based on this, there are currently some tooth surface finishing machines on the market, all of which use tools to smooth the bump marks and small burrs on the gear tooth surface to reduce gear noise. These tooth surface finishing machines can be divided into two categories: one One is a tooth surface finishing machine using honing technology, which achieves the effect of tooth surface finishing through tool honing wheel cutting, but the disadvantage is that cutting will destroy the tooth profile and reduce the precision of the too...

[0003] Based on this, there are currently some tooth surface finishing machines on the market, all of which use tools to smooth the bump marks and small burrs on the gear tooth surface to reduce gear noise. These tooth surface finishing machines can be divided into two categories: one One is a tooth surface finishing machine using honing technology, which achieves the effect of tooth surface finishing through tool honing wheel cutting, but the disadvantage is that cutting will destroy the tooth profile and reduce the precision of the tooth profile; the other category has foreign A three-wheel calender, which uses three rolling wheels as tools, can achieve the effect of smoothing the tooth surface, but the cost of the machine tool is expensive, and it is a tooth surface skinning machine with high cost and low efficiency
