The railway wagon brake pipe system joint body all-position welding device comprises a support platform. The key technology is that a pneumatic three-jaw chuck and a rotary platform driven by a direct-current motor are fixedly installed on the support platform; the rotary platform and the pneumatic three-jaw chuck are coaxial, and the rotary platform rotates relative to the pneumatic three-jaw chuck; a pneumatic V-shaped clamping component is arranged in a position on the support platform, which is corresponding to the pneumatic three-jaw chuck; and an auxiliary bracket is arranged in a position corresponding to the pneumatic V-shaped clamping component. According to the invention, a brake pipe system can be welded in a convenient, safe and labor-saving way in all positions; the positioning accuracy is high; the production safety is ensured; the welding quality is high; unqualified products are reduced; and the production efficiency is high.
Description
Technical field
A kind of railway wagon brake pipe fastening joint body all position welding connection device, belongs to welding production equipment, the welding equipment of braking pipe arrangement of especially growing up.
Background technology
China railways Freight Car Braking System adopts compressed air as braking driving source, operates control train operation by changing atmospheric pressure.Brakes is primarily of each control valve, braking pipe arrangement, brake rigging composition, and braking pipe arrangement, for transmitting compressed air, after wherein braking pipe arrangement welds with fittings body primarily of pipe, then is connected on car body with securing member.
At present, brake pipe welding adopts vertical welding, and pipe and fittings body are installed and locate simply, although weld seam welding position is good, and pipe fitting and fittings body perpendicularity, ensuring coaxiality difficulty.Meanwhile, following problem is existed for vertical welding: pipe fitting feeding, discharge difficulty of growing up, operator need repeatedly by reaching about 5 meters, the 15 kilograms of pipes that weigh remove to vertical state from level, postwelding keeps flat again, labour intensity is large, wayward, and pipe is easily toppled over and causes security incident; In addition because welding operation is carried out in indoor, indoor have overhead traveling crane to advance, and after long pipe is vertically placed, will interfere, and also easily cause security incident with overhead traveling crane.
Summary of the invention
The problem to be solved in the present invention be exactly for above not enough and provide a kind of can be convenient, safe, laborsaving, and the welder of all-position welding braking pipe arrangement.Its technical scheme is as follows:
It comprises brace table, and its key technology is the turntable fixedly mounting pneumatic scroll chuck and driven by direct current generator on supporting station, and the coaxial and turntable of turntable and pneumatic scroll chuck rotates relative to pneumatic scroll chuck; On brace table, V type clamping part is installed in the position of corresponding pneumatic scroll chuck; In the position corresponding with V type clamping part, auxiliary bracket is installed.
Compared with prior art the present invention has following beneficial effect:
1. positioning precision is high: this mechanism, using fittings body end face as longitudinal register benchmark, adopts pneumatic scroll chuck, fittings body automatic centering is located, and adopts V type clamping part by pipe fitting pneumatic pinch simultaneously, ensures two workpiece relative sizes, positional precision.After two workpiece automatic centerings, carry out all-position welding, after realizing welding, fittings body and pipe fitting longitudinal centre line perpendicularity are not more than 0.3mm within the scope of 100mm, within the scope of 200mm, be not more than 0.5mm.
2. guarantee production safety: compared with existing vertical welding, long tube adopts horizontal mode to carry out welding can avoid toppling over of cargo handling process piping, operative is rationally convenient, also can not interfere with the contour empty body of overhead traveling crane during welding, reduces security incident occurrence risk.
3. welding quality is high, reduces defective work: compared with manual welding, adopt this device appearance of weld attractive in appearance; better can ensure weldquality, reduce and reprocess operation, reduce production cost; for guaranteeing that Freight Car Braking System pipe fitting is without sewing, improving railway freight-car traffic safety and providing safeguard.
4. production efficiency is high: adopt this device to carry out all-position welding, and relative to employing manual welding, speed of welding can improve 30%, and production efficiency improves greatly.

Detailed description of the invention:
See Fig. 1-Fig. 7, the present invention includes brace table 5, its key technology is the turntable 1 fixedly mounting pneumatic scroll chuck 2 and driven by direct current generator on supporting station 5, coaxial and the turntable 1 of turntable 1 and pneumatic scroll chuck 2 rotates relative to pneumatic scroll chuck 2, turntable 1 is connected with weld gun component, and direct current generator driven rotary platform rotates and the relatively-stationary fittings body of welding gun (workpiece) is rotated; Three movable jaws 8 that pneumatic scroll chuck comprises disk 6 and is distributed on disk 6, be centring ring 7 between movable jaw 8 at the middle part of disk 6, pneumatic scroll chuck utilizes moving radially of three uniform movable jaws, fittings body clamping and location.On brace table 5, V type clamping part 3 is installed in the position of corresponding pneumatic scroll chuck 2, V type clamping part 3 comprises left and right two V-type chucks 9, cylinder 10 and linkages 11, two the V-type chucks 9 in left and right are respectively by seat supports, bearing is positioned on slide rail 12, and bearing is connected with cylinder 10 by linkage 11.Install auxiliary bracket 4 in the position corresponding with V type clamping part 3, auxiliary bracket 4 installs V-block 13 at pedestal upper end, installs ball 14, facilitate the slip of pipe fitting in V-block 13.
Operating process of the present invention is:
1, manually placement positioning pin to the centring ring 7 of delta air chuck, after alignment pin end face contacts with movable jaw 8, clamping and positioning pin, alignment pin automatic centering, fittings body is placed on alignment pin, realizes fittings body centering;
2, place pipe fitting manually, pipe fitting front end is positioned on the V-type chuck 9 of V type clamping part 3, and pipe fitting rear end is positioned on the V-block 13 of auxiliary bracket 4, in V-block 13, install ball 14, facilitate the slip of pipe fitting, the bearing of V-type chuck slides on slide rail 12, for adapting to the different pipe fitting of length, when cylinder stretches out, V-type chuck is opened, when cylinder bounces back, V-type chuck clamps, and pneumatic pinch pipe fitting, after pneumatic pinch, auxiliary bracket 4 holds up workpiece, plays supplemental support effect to workpiece;
3, start welding button, direct current generator is after reductor slows down, and driven rotary platform and turntable welding gun together opposite piece rotate, and reach all-position welding object;
4, automatic welding one stops after enclosing, and unclamps V type clamping part, takes workpiece away, next workpiece, and repeat above action.
According to varying in size of welding caliber, φ 17 ~ φ 32 and φ 32 ~ φ 66 two kinds can being divided into, when welding φ 17 ~ φ, 66 caliber, two, left and right V-type chuck 9 installing two movable clip blocks respectively, reach the requirement of clamping small workpiece.
