Description

Be used to apply the immersion trough hoisting mechanism of line

Technical field

The present invention relates to a kind of immersion trough hoisting mechanism that is used to apply line, belong to the assistant conveyance frock technical field that coating machine transports coated workpiece.

Background technology

For metal works; Usually need carry out Shot Blasting to the metal surface high velocity jet through abrasive material; The mechanical performance of workpiece outer surface is changed; And in impact and the shear action of abrasive material to surface of the work; Certain cleannes and different roughness that the surface of workpiece is obtained; The mechanical performance of surface of the work is improved; Improve the fatigue resistance of metal works and the adhesive force between metal surface and the coating; Inorganic compound being applied is in the metal surface again, applies the oxide film of ability corrosion protection ability artificially.Metal works after treatment such as securing member etc. are put into the workpiece basket through feed mechanism at present; Be equipped with on the immersion trough of masking liquid and move; The workpiece basket is placed on immersion trough; Through the masking liquid in the immersion trough workpiece is carried out dip-coating; And after dip-coating finishes; Again immersion trough is moved down; Automatic coating machine is under motor-driven; Making coating machine drive the workpiece basket rotates at a high speed coating equably attached to the workpiece that is coated with; And unnecessary water or liquid dried fast and effectively, last workpiece basket through conveying device to shedding mechanism with the part discharging.Therefore in coating procedure,, need one or many that workpiece is carried out dip-coating, therefore need often immersion trough to be moved up and down according to the coating processes requirement.Immersion trough is to be placed on the hydraulic platform at present, and through the up-down of control hydraulic platform, and immersion trough needs often to change coating, and it is very inconvenient therefore to move immersion trough.

Summary of the invention

The purpose of this invention is to provide a kind of rational in infrastructure, operation is light, can improve the immersion trough hoisting mechanism that is used to apply line of functional reliability.

The present invention is that the technical scheme that achieves the above object is: a kind of immersion trough hoisting mechanism that is used to apply line; It is characterized in that: comprise two standpipes and the supporting base that is fixed on two riser top; Motor and the decelerator that is connected with motor are installed on the said supporting base; The both sides of supporting base are separately installed with the diaxon bearing; The two ends of driving shaft are installed on the bearing block through bearing respectively; Two sprocket wheels are installed on the driving shaft respectively; Be installed in driven wheel and idler gear engagement on the reducer output shaft; And idler gear is connected with driving shaft; Two chains respectively with separately sprocket engagement; Two chains pass the sprocket hole on the supporting base respectively; One end of chain is connected with lifting arm one end; The other end is connected with balancing weight; Promoting bearing is fixedly connected with two lifting arms; Promote bearing and comprise bottom girder; Be fixed on side plate or the curb girder and the back of the body beam formation of bottom girder both sides; And bottom girder is provided with the wheel support seat, and the horizontal respectively connecting rod that is installed on two lifting arms is connected with roller, and roller is arranged in the gathering sill of standpipe; Also be separately installed with anti-contrary wheel seat with respect to two sprocket wheel opposites on the supporting base, anti-contrary wheel shaft is installed on the anti-contrary wheel seat, and anti-contrary wheel is installed in anti-contrary wheel shaft through bearing, and anti-contrary wheel is relative with chain.

The present invention is fixed on supporting base at the top of standpipe; And motor; Decelerator and bearing block are installed on the supporting base; Driving shaft is installed in the diaxon bearing through bearing; And two sprocket wheels are fixedly connected on the driving shaft; Through driving shaft two sprocket wheels are rotated simultaneously; The chain that two sprocket wheels are mated respectively can move up and down simultaneously; Rational in infrastructure; Chain of the present invention drives lifting arm and can move up and down with respect to standpipe; Be connected with lifting arm owing to promote bearing, promote on the bearing, drive the lifting bearing through lifting arm and move up and down when immersion trough is placed on; Immersion trough is also moved up and down, can satisfy the technological requirement that applies different workpieces.The present invention is provided with the wheel support seat promoting on the bottom girder of bearing, therefore can put just immersion trough to be placed on to promote on the bearing and immersion trough is carried out spacing, and the loading and unloading immersion trough is easy to operate.Sprocket wheel of the present invention is installed on the driving shaft; And driving shaft by motor through decelerator and intermediate gear drives; So drive shaft two sprocket wheels are rotated simultaneously; Control lifting arm simultaneously and drive to promote bearing and move up and down and reach; Lifting arm of the present invention is connected with roller through connecting rod, and roller is arranged in the gathering sill of standpipe, can make chain drive lifting arm and promote bearing to stablize mobile up and down; Resistance when also reducing simultaneously the lifting arm motion promotes bearing and moves up and down light.The present invention also is equipped with two anti-contrary wheel seats on supporting base; Two anti-contrary wheels are installed in respectively on the anti-contrary wheel seat; Because anti-contrary wheel is relative with chain; Can make chain normally along the sprocket wheel normal rotation; Have no progeny and work as chain; Through anti-contrary wheel chain or chain joint are blocked, prevent to promote bearing and move down fast, therefore increased substantially the functional reliability of immersion trough hoisting mechanism.
