Description

A kind of railway freight-car braking pipe arrangement fittings body all-position welding device
Technical field
A kind of railway freight-car braking pipe arrangement fittings body all-position welding device belongs to the welding production equipment, the welding equipment of the braking pipe arrangement of especially growing up.
Background technology
The China railways Freight Car Braking System adopts compressed air as the braking driving source, controls train operation through changing atmospheric pressure.Brakes mainly is made up of each control valve, braking pipe arrangement, brake rigging, and braking pipe arrangement is used to transmit compressed air, after wherein braking pipe arrangement is mainly welded by pipe and fittings body, is connected on the car body with securing member again.
At present, brake pipe welds and adopts vertical welding, and pipe is installed the location simply with fittings body, though the weld seam welding position is good, pipe fitting and fittings body perpendicularity, axiality guarantee difficulty.Simultaneously, there is following problem for vertical welding: the upper and lower material difficulty of the pipe fitting of growing up, the operator needs to reach about 5 meters repeatedly, the 15 kilograms of pipes that weigh are removed to vertical state from level; Postwelding keeps flat again; Labour intensity is big, and is wayward, and pipe is toppled over easily and caused security incident; Because welding operation is carried out indoor, and indoor have overhead traveling crane to advance, long pipe will be interfered with overhead traveling crane after vertically placing in addition, also be prone to cause security incident.
Summary of the invention
The problem that the present invention will solve provides a kind of ability convenient, safe, laborsaving exactly to above deficiency, and the welder of all-position welding braking pipe arrangement.Its technical scheme is following:
It comprises brace table, and its key technology is the turntable that on supporting station, fixedly mounts pneumatic scroll chuck and driven by direct current generator, the coaxial and pneumatic relatively scroll chuck rotation of turntable of turntable and pneumatic scroll chuck; Pneumatic V-type clamping part is installed in the position of corresponding pneumatic scroll chuck on brace table; In the position corresponding auxiliary bracket is installed with pneumatic V-type clamping part.
Compared with prior art the present invention has following beneficial effect:
1. positioning accuracy is high: this mechanism as the longitudinal register benchmark, adopts pneumatic scroll chuck with the fittings body end face, with fittings body automatic centering location, adopts pneumatic V-type clamping part with the pipe fitting pneumatic pinch simultaneously, guarantees two workpiece relative sizes, positional precision.After the two workpiece automatic centerings, carry out all-position welding, realize that welding back fittings body and pipe fitting longitudinal centre line perpendicularity are not more than 0.3mm in the 100mm scope, be not more than 0.5mm in the 200mm scope.
2. guarantee production safety: compare with existing vertical welding; Long tube adopts horizontal mode to weld can avoid toppling over of cargo handling process piping; The workman is more convenient to operate rationally, also can not interfere with high-altitude object such as overhead traveling crane during welding, reduces security incident occurrence risk property.
3. welding quality is high, reduces defective work: compare with manual welding, adopt this device appearance of weld attractive in appearance; Can better guarantee weldquality, reduce and reprocess operation, reduce production cost; Sew for guaranteeing that the Freight Car Braking System pipe fitting does not have, improve the railway freight-car traffic safety and provide safeguard.
4. production efficiency is high: adopt this device to carry out all-position welding, with respect to adopting manual welding, speed of welding can improve 30%, and production efficiency improves greatly.

The specific embodiment:
Referring to Fig. 1-Fig. 7; The present invention includes brace table 5; Its key technology is the turntable 1 that on supporting station 5, fixedly mounts pneumatic scroll chuck 2 and driven by direct current generator; Turntable 1 and pneumatic scroll chuck 2 coaxial and pneumatic relatively scroll chuck 2 rotations of turntable 1, turntable 1 is connected with the welding gun parts, and the rotation of direct current generator driven rotary platform makes the relatively-stationary fittings body of welding gun (workpiece) be rotated; Pneumatic scroll chuck comprises disk 6 and is distributed in three movable jaws 8 on the disk 6, is centring ring 7 between movable jaw 8 at the middle part of disk 6, and pneumatic scroll chuck is to utilize moving radially of three movable jaws being uniformly distributed with, clamps fittings body and the location.Pneumatic V-type clamping part 3 is installed in the position of corresponding pneumatic scroll chuck 2 on brace table 5; Two V-type chucks 9, cylinder 10 and linkages 11 about pneumatic V-type clamping part 3 comprises; About two V-type chucks 9 respectively by seat supports; Bearing is positioned on the slide rail 12, and bearing is connected with cylinder 10 through linkage 11.With pneumatic V-type clamping part 3 corresponding positions auxiliary bracket 4 is being installed, auxiliary bracket 4 is in the support upper end V-block 13 to be installed, and ball 14 is installed in V-block 13, makes things convenient for the slip of pipe fitting.
Operating process of the present invention is:
1, the placement positioning pin is to the centring ring 7 of delta air chuck manually, and the alignment pin end face is with after movable jaw 8 contacts, the clamping and positioning pin, and the alignment pin automatic centering, fittings body is placed on the alignment pin, realizes fittings body centering;
2, place pipe fitting manually, the pipe fitting front end is positioned on the V-type chuck 9 of pneumatic V-type clamping part 3, and the pipe fitting rear end is positioned on the V-block 13 of auxiliary bracket 4, and ball 14 is installed in V-block 13; Make things convenient for the slip of pipe fitting, the bearing of V-type chuck slides on slide rail 12, is used to adapt to the different pipe fitting of length, when cylinder stretches out; The V-type chuck is opened, and when cylinder bounced back, the V-type chuck clamped, the pneumatic pinch pipe fitting; After the pneumatic pinch, auxiliary bracket 4 holds up workpiece, and workpiece is played the supplemental support effect;
3, start the welding button, direct current generator is after reductor slows down, and driven rotary platform and turntable welding gun be workpiece rotation relatively together, reaches the all-position welding purpose;
4, stop after welding a circle automatically, unclamp pneumatic V-type clamping part, take workpiece away, next workpiece, and repeat above action.
According to welding the varying in size of caliber, can be divided into 66 two kinds of φ 17~φ 32 and φ 32~φ, when welding φ 17~φ 66 calibers, about two movable clip blocks are installed on two V-type chucks 9 respectively, reach the requirement of clamping small workpiece.
