Description

A kind of smoking dust discharge cover for Gear by Laser welding

Technical field

The utility model relates to gear fully-automatic laser welding equipments, belong to field of laser processing.Applied to automobile manufacture The gear welding process of industry promotes gear manufacture quality.The utility model provides a kind of smoking for Gear by Laser welding Dust discharge cover leads to the design to air duct, improves the collection to weld fumes and spatter and effect is discharged, promote gear face of weld Bare headed eyeglass and working environment are welded in quality, protection.

Background technique

Auto industry is play an important role in Chinese national economy, and especially automobile manufacture industry development in recent years is fast Suddenly, gear is one of indispensable part on automobile.Demand is big, complex process.Early stage gear welding method is generally electricity Welding resistance, electron beam welding, induction welding, it is desirable that weld under vacuum conditions, complex technical process, working efficiency is low, and product quality is not It is high.With the continuous progress of technology and the promotion of business economic strength, domestic and international 70% product is using laser welding work Skill has many advantages, such as to weld deep stabilization, production capacity height, deforms small, to produce such as my company gear welding machine.At present to flue dust and welding The collection method of splashing passes through a variety of tests, and using smoking dust discharge nozzle against bead direction smoking dust discharge, method is simple, can only Part flue dust is drawn, smoke evacuation is slow, and to spatter almost without effect, the flue dust of omission can generate following harm: 1) polluting ring People from border will lead to a variety of occupational diseases after sucking；2) a large amount of splashing flue dust can also pollute eyeglass, damage eyeglass, influence welding effect Fruit；3) flue dust delay will affect appearance of weld, and welding is caused to interrupt or formed welding defect.

With product quality require continuous improvement, domestic enterprise constantly improve technological equipment, especially environmental protection and The raising of employee's level of protection promotes working environment.The characteristics of when being welded according to gear, laser go out photocoagulation in fixed position, Gear weld seam welding is completed in gear rotation.Volume of smoke can be concentrated in welding pool position and fly to top, partially in bond pad locations Diffusion.Smoking dust-exhausting port influences weldquality apart from the too close proper flow that just will affect welding protection gas of bond pad locations.It smokes Dust-exhausting port is too far apart from bond pad locations and smoking dust discharge protection weld seam is not achieved and welds the effect of bare headed eyeglass.

In order to study the collection discharge of flue dust and spatter, our company receives from laser welding process, welding process, flue dust Collection and smoke and dust purifier have carried out deep practice.The especially arrangement and structure etc. of smoking dust discharge cover suction inlet position, By improving three times and perfect, collection discharge of the satisfaction to flue dust and spatter.Smoking dust discharge cover structure has following features: 1) Fusion does not interfere laser welding head to work on gear welding bench；2) to gear product good compatibility, frequently adjustment is not had to Suction opening position and replacement smoking dust discharge cover, meet product specification frequent changes requirement；3) smoking dust discharge excellent effect, in negative pressure 4500Pa, flow 2200M³Under the action of/h centrifugal high pressure fan, 95% or more flue dust and spatter can be extracted；4) service life It is long, it is at low cost.It can be used 10000 hours or more and do not have to maintenance.

Utility model content

The purpose of this utility model is to provide a kind of smoking dust discharge covers for Gear by Laser welding, and it is complete to be applied to gear Automatic laser welding equipment is completed the collection to weld fumes and spatter and is discharged, meets high-quality duplicate gear Laser Welding Connect technique requirement.The utility model relates to a kind of smoking dust discharge covers for Gear by Laser welding, it is characterised in that: 1) smoke row Dust hood is divided to two regions, and first region is inner cavity, is separated by inner ring 4, and welding is drawn under negative pressure gas flow effect in inner cavity The flue dust of molten bath position splashes and diffuses up flue dust, and Two Areas is external ring cavity, by enclosing 5 under 1 lower plate of upper plate, 2 side wall 3 Composition, the splashing that external ring cavity draws diffusion flue dust and be scattered under negative pressure gas flow effect；2) smoking dust discharge cover uses stainless steel Material welding manufacture, surface polishing treatment.Answering on gear fully-automatic laser welding equipment is covered below with reference to the smoking dust discharge With the utility model is described in further detail.

Detailed description of the invention

Fig. 1 be the utility model Gear by Laser welding smoking dust discharge cover structure schematic diagram, mainly form: upper plate 1, under Plate 2, side wall 3, inner ring 4, under enclose 5, connecting tube 6.Working principle are as follows: the connecting pipe of smoke and dust purifier high pressure blower and the pumping Cigarette dust discharge cover connecting tube 6 is connected, and encloses 5 special pipes being welded under connecting tube 6 and 1 lower plate of upper plate, 2 side wall 3, separates in inner ring 4 Special pipe mouth forms two regions, first area inner cavity and second area external ring cavity, and two regions are same when high pressure blower works When form negative pressure, the collection of weld fumes and spatter is discharged.It is used by user's actual production, workpiece surface noresidue Splash and flue dust trace, this smoking dust discharge cover meet Gear by Laser welding equipment requirement of shelter.

Specific embodiment

Smoking dust-exhausting port is compact-sized, rationally distributed.Specific embodiment is as follows:

Collection to weld fumes and spatter: as shown in Figure 1, smoke and dust purifier exhausting by connecting tube 6 with it is upper 5 special pipes being welded into are enclosed under 1 lower plate of plate, 2 side wall 3, are formed in the inner cavity that the separation special pipe mouth of inner ring 4 is formed and annular chamber negative The collection of weld fumes and spatter is discharged in pressure.

The utility model is applied to the smoking dust discharge cover of Gear by Laser welding, passes through pipeline and smoke and dust purifier high-pressure blast Machine is connected, and smog reaches air standard discharge after smoke and dust purifier purifies, while smoke and dust purifier is provided with solid Particle collector, the splash collection generated to laser beam welding and regular manual cleaning.Smoking dust discharge cover is applicable not only to The smog and splash of Gear by Laser welding are collected, while being suitable for the laser beam welding of other products.
