Abstract
The invention relates to a gear ring processing method, which is characterized by comprising the steps of: firstly, carrying out carburization prevention treatment on a welding line part of a slave cylindrical gear and neighboring surfaces thereof, positioning and clamping a gear ring on a welding end face of a carburization-free layer of the slave cylindrical gear by adopting a special clamp as required, and carrying out laser welding on the gear ring and the slave cylindrical gear by using a titling-type numerical control rotary table and a light guide system of a reflection type focusing structure; wherein 3-11 short welding lines are discontinuously and uniformly distributed along a gear ring welding circumference, each welding line is 2-15mm in length, 0.5-2mm in width and 2-8mm in weld penetration. In the invention, the laser cutting precision on an ABS (Acrylonitrile Butadiene Styrene) gear ring is high, the ABS gear ring is welded on a cylindrical gear through laser, the connection strength is high, the influence of welding heat is low and the deformation is small; and the entire system has compact structure and light weight, is simple and reliable, is easy for the arrangement of the whole machine and free of maintenance, and can prevent gear ring from falling.
Description
Technical field
The present invention relates to a kind of method of ring gear machining, the built-in ABS gear ring particularly relating to a kind of automobile portal drive axle or gate-type steering and driving axle (comprising independent suspension to hang with dependent) and driven cylindrical gear realize the method be connected by laser weld; Belong to laser welding technology field.
Background technology
Portal drive axle can not adopt integrative-structure manufacture because of its ABS gear ring of limited space and driven cylindrical gear, can only take the processing mode that split manufacture links into an integrated entity again; And ABS gear ring wall is thin, and with gear connection position area stenosis, ensure that ABS gear ring is connected with gear reliably, precision is high, it is little to be out of shape, difficulty is very large, and common process cannot realize.
Summary of the invention
The object of the present invention is to provide a kind of method of ring gear machining, is the method for attachment of a kind of ABS gear ring and driven cylindrical gear, adopts sheet metal to manufacture ABS gear ring, utilizes laser cutting technique to process ABS gear ring; Allowance is reserved in wheel driven cylindrical gear welding position, limit, and processing is removed welding position carburized layer or adopted Coating Method to carry out cement protection to driven cylindrical gear welding position.
Technical scheme of the present invention is achieved in that a kind of method of ring gear machining, it is characterized in that: adopt the special fixture with positioning and clamping function that ABS gear ring is located clamping in the welding end surface of driven cylindrical gear, because of gear ring and gear connection position area stenosis, fixture, while guarantee ABS gear ring welds positioning precision with driven cylindrical gear, can not disturb the incidence of laser beam in laser beam welding; ABS gear ring and gear component clamping can inclined on the chuck of NC rotary table, with He-Ne light-seeking laser beam, adopt the light-conducting system of reflective focusing structure by the beam transmission after focusing to center, gear ring weld metal zone, laser beam focus focus defocusing amount :-2mm ~+2mm; In laser beam welding, laser instrument Output of laser power 1KW ~ 4KW; Speed of welding 0.5 ~ 5.0m/min; One or more gases such as gas and compressed air in nitrogen, argon gas or helium are adopted to protect welding pool and optical element in welding process in welding process, gas flow 5 ~ 25L/min.
Adopt the laser weld modes such as laser lap weldering, laser fillet welding, laser butt welding, along gear ring welding circumference intermittently, be uniformly distributed 3 ~ 11 short weld seams, every bar fusion length 2 ~ 15mm, weld width 0.5 ~ 2mm, weld penetration 2 ~ 8mm.
Good effect of the present invention is: ABS gear ring Precision of Laser Cutting is high; ABS gear ring Laser Welding is contained on stud wheel, and bonding strength is high, welding heat affected little, is out of shape little; Whole system compact conformation, simple and reliable, lightweight, be easy to arrangement, avoid gear ring to come off, and there is non-maintaining property.
Detailed description of the invention
Below in conjunction with embodiment, the present invention will be further described:
Embodiment 1:
Coating Method or processing removal method is adopted to carry out anti-carburizi ng process to the weld seam position of wheel limit driven cylindrical gear and neighbouring surface thereof, to make this position without carburized layer after gear wheel carburization heat treatment, to ensure the serviceability of reliability and the weldment welded.On the sheet metal identical with ABS gear ring thickness, process ABS gear ring with laser cutting technique.Adopt the special fixture with positioning and clamping function that ABS gear ring is located clamping in the welding end surface of driven cylindrical gear, because of gear ring and gear connection position area stenosis, fixture, while guarantee ABS gear ring welds positioning precision with driven cylindrical gear, can not disturb the incidence of laser beam in laser beam welding; ABS gear ring and gear component clamping can inclined on the chuck of NC rotary table, weldment is rotated on request in laser beam welding, to realize different speeds of welding.With He-Ne light-seeking laser beam, adopt the light-conducting system of reflective focusing structure by the beam transmission after focusing to center, gear ring weld metal zone, laser beam focus focus defocusing amount :-2mm ~+2mm.In laser beam welding, laser instrument Output of laser power 1KW ~ 4KW; Speed of welding 0.5 ~ 5.0m/min; One or more gases such as gas and compressed air in nitrogen, argon gas or helium are adopted to protect welding pool and optical element in welding process in welding process, gas flow 5 ~ 25L/min.Laser weld mode: overlap welding, butt welding, fillet welding, interrupted along gear ring welding circumference, be uniformly distributed 3 ~ 11 short weld seams, every bar fusion length 2 ~ 15mm; Weld width 0.5 ~ 2mm, weld penetration 2 ~ 8mm.
