Description

Numerical control low module straight bevel (gear) generator

Technical field

This utility model belongs to gear shaper manufacturing technology field, more particularly to a kind of numerical control low module straight bevel gear plane Tooth machine.

Background technology

Low module straight bevel gear is widely used in the fields such as space flight, aviation, robot building, and low module straight-tooth bores tooth Wheel has good market prospect as small-sized or micromachine drive disk assembly part, and demand is big.Because module is less More it is difficult to process, be difficult to meet tooth-formation of gear, tooth alignment error requirement and machining accuracy.

While the cutter of low module straight bevel (gear) generator does high speed reciprocating stroke movement on the guide rail of knife block Complete to allow knife action.So-called the knife action is allowed to be exactly: in planing impulse stroke, planing tool lifts and has enough cutter lifting strength, Machining locus also to be ensured are correct simultaneously.When cutting return, cutter should depart from the machined flank of tooth, and planing tool is fallen, cutter Can not cut or scratch the machined flank of tooth, relieving amount is as big as possible.Therefore, knife motion is allowed to directly influence the machining locus of gear And machining accuracy, the size of relieving amount also determines the working (machining) efficiency of gear (can cut) with roughing feed amount.So low module is straight Bevel gear numerical control gear shaper allow knife telecontrol equipment and adjustment very crucial, decide the success or not of machine tool motion.

Straight bevel (gear) generator relieving mechanism of the prior art, the structure of general employing is: tool rest bracket and ram Between have a set of clamping plate mechanism to clamp one to allow knife pull bar, allow knife pull bar front end connect a connecting rod, connecting rod connects a cam, Swung around a gyroaxis by cam push-and-pull knife clip, formed and allow knife to move.This structure exists not enough as follows: 1, above-mentioned allows Cutter mechanism is arranged between tool rest bracket and ram, and structure complex it is impossible to be used in the low module straight-tooth of compact conformation On bevel gear gear shaper；2nd, the allow knife, revert action of above-mentioned relieving mechanism is to allow knife pull bar make folder knife by clamping plate mechanism clamping Plate swings, and allows knife action not to be quick enough, reliably；3rd, above-mentioned relieving mechanism cannot adjust relieving amount because its structure limits.

The knife up guiding mechanism of straight bevel (gear) generator, typically adopts taper wedge key structure, comprising: tool-post structure, wedge Pin and wedge key, described taper is close to the cammed surface of wedge key, and taper is held out against by holding screw, and tool-post structure is connected with wedge key, plane Knife is arranged on tool-post structure, precession holding screw, makes taper promote wedge key to move, planing tool and tool-post structure synchronously move with wedge key Dynamic, the height of planing tool is adjusted with this.Said structure in use, often occurs and leads to it oblique because of taper intensity deficiency Wedge surface damages or because wedge angle not leads to self-locking, causes knife up to adjust the problem of disabler；Further, since accessory size Restriction, there is also and lead to not because cammed surface is too short meet the problem of knife up adjusting range.
