Description
Technical field
The invention belongs to locomotive manufacture field, and in particular to a kind of locomotive welding automatic positioning platform.
Background technology
Welding：Also referred to as welding, Rong connects, and is a kind of jointing metal in a manner of high temperature or high pressure or other thermoplasticity materials
The manufacturing process and technology of material.There are three types of modes for welding：Melting welding, pressure welding and soldering, wherein melting welding refers to being intended to engage by heating
Workpiece be allowed to be partially melting to form molten bath, be added in molten bath it is molten fills out object auxiliary, just so that workpiece connects after the cooled and solidified of molten bath
It is combined, is suitble to the welding processing of various metals and alloy.To ensure preferable stability, frequently with melting welding in locomotive processing
Two blocks of steel plates of mode pair be fixed.
The existing device applied to locomotive welding, including cross bar, cross bar both ends are equipped with the clamping for clamping steel plate
Unit slidably connects plumb joint on cross bar.To avoid the movement of welding process light plate that processing is caused to fail, need to pass through clamping
Unit clamps the both ends at two pieces of steel plate places to be joined.Restart plumb joint, mobile plumb joint and steel plate contact, treats joint
It is welded.
Above-mentioned apparatus there are the problem of have：In process, the size of two blocks of steel plates is different in many cases, two blocks of steel
The place edge to be joined of plate can not be completely superposed, and clamping unit is caused to be difficult to clamp two blocks of steel plates.
Invention content
The purpose of the present invention is to provide a kind of locomotives to weld automatic positioning platform, is difficult to solving welding process light plate
The problem of clamping.
In order to achieve the above objectives, base case of the invention is：A kind of locomotive welding automatic positioning platform, including rack,
It is equipped with first crossbar, montant, second crossbar and workbench, first crossbar, montant and second in rack successively from top to bottom
The central axes of cross bar are vertical two-by-two, and first crossbar and workbench are each attached in rack, and montant upper end is slidably connected at first
On cross bar, montant lower end is slidably connected in second crossbar, be fixedly connected sequentially in second crossbar have cold pressing block, plumb joint and
Hot wafering；Second crossbar is fixedly connected with ball-screw close to one end of cold pressing block, and nut, spiral shell are threaded on ball-screw
Mother is rotatably connected in rack, and cam is fixedly connected on nut, and piston bucket is fixedly connected in rack, and the interior sliding of piston bucket connects
It is connected to piston, piston rod, piston rod one end and cam slide cooperation far from piston are fixedly connected on piston；Rack is equipped with
Vortex tube, vortex tube include inlet end, cold air outlet side and hot gas outlet side, and inlet end is connected to piston bucket, in hot wafering
Equipped with the hot air cavity being connected to hot gas outlet side, the cold air cavity being connected to cold air outlet side is equipped in cold pressing block.
The operation principle of this base case is：
Workbench is for placing steel plate to be welded.Mobile montant so that montant is slided along first crossbar, second crossbar
As montant slides, when second crossbar is moved to the top for needing weld, stop mobile montant.With hot wafering direction
For direction of advance, mobile second crossbar, ball-screw and second crossbar move together, and ball-screw and nut form ball-screw
Pair realizes nut rotation, cam is with nut rotation according to the characteristic of ball screw assembly, not self-locking.Cam and piston rod composition are convex
Mechanism is taken turns, according to the kinetic characteristic of cam mechanism, piston rod does linear reciprocating motion.Piston and piston bucket form piston structure,
According to the kinetic characteristic of piston structure, piston rod does linear reciprocating motion with piston can realize the air inlet of piston bucket, outlet.
The gas of piston bucket discharge enters in vortex tube, isolates cold air and hot gas, cold air is drained into cold pressing by cold air outlet side
In block, hot gas is drained by hot gas outlet side in hot wafering.
In second crossbar moving process, hot wafering, plumb joint and cold pressing block are contacted with steel plate successively, start plumb joint,
Plumb joint and upper surface of steel plate contact, weld steel plate.Hot wafering and cold pressing block carry out steel plate in the both sides of plumb joint
Compress, even if the size of two blocks of steel plates differs, while plumb joint and steel plate contact, hot wafering and cold pressing block at least one
It can be with steel plate contact so that steel plate is compacted.Hot wafering is first contacted with steel plate, is preheated to steel plate, and welding stress is reduced, it
Plumb joint is welded again afterwards, and after the completion of plumb joint welds, cold pressing block and the part contact welded radiate cold
But so that weld fast shaping.
The advantageous effect of this base case is：
1, in welding process, hot wafering and cold pressing block are always to needing weld to compress, even if the size of two blocks of steel plates is not
One, while plumb joint and steel plate contact, hot wafering and at least one meeting of cold pressing block and steel plate contact so that steel plate is pressed
Tightly.
2, using structures such as ball screw assembly, cam mechanism and piston structures, drive plumb joint to steel in second crossbar
While plate is welded, realizes and vortex tube is supplied automatically, high degree of automation.
3, hot wafering, plumb joint, cold pressing block are contacted with steel plate successively, and hot wafering is first contacted with steel plate, are carried out to steel plate pre-
Heat reduces welding stress, and plumb joint is welded again later, and after the completion of plumb joint welds, cold pressing block and the portion welded
Tap is touched, and carries out cooling so that weld fast shaping.
Further, first crossbar both ends have been bolted clamping jaw.
Advantageous effect：After removing bolt, the angle between clamping jaw and first crossbar, the inner end of clamping jaw and steel can be adjusted
After plate contact, it is bolted clamping jaw.Both ends of the steel plate far from place to be joined are clamped by clamping jaw, avoid hot wafering and cold
During compressing steel plate downwards, steel plate deviates briquetting to close to clamping jaw direction.
Further, first crossbar lower end is equipped with the first sliding groove, and montant upper end is slidably connected in the first sliding groove, the first sliding groove
Interior to be equipped with several card slots, montant upper end is additionally provided with groove, magnetic patch is slidably connected in groove, fixed between magnetic patch and bottom portion of groove
It is connected with spring, the interior electromagnet being equipped with for repelling magnetic patch of groove and the power supply powered for electromagnet, is set on montant outer wall
There are button switch, button switch, power supply and electromagnet series connection.
Advantageous effect：When electromagnet is closed, the sucking action between iron core and magnetic patch in electromagnet makes magnetic patch be located at
In groove, montant can be slided along the first sliding groove.When montant slides into designated position, trigger button switch starts electromagnetism
Iron, electromagnet repel magnetic patch so that and magnetic patch skids off groove, and magnetic patch is caught in card slot, realizes fixation of the montant in first crossbar,
It avoids in second crossbar sliding process, montant generates movement.Whole process need not manually fix montant, high degree of automation.
Further, cold pressing block is fixedly connected with cutter close to the side of plumb joint.
Advantageous effect：In welding process, the drop of steel plate melting is easy soldered head drive and drops on surface of steel plate, in steel
Plate surface forms protrusion.Cold pressing block drives cutter that can strike off the drop for dropping in surface of steel plate in moving process.
Further, worktable upper surface is fixedly connected with magnetic stripe.
Advantageous effect：By the sucking action between magnetic stripe and steel plate, further avoids steel plate and move on the table.
