The invention discloses a welder for an automotive door bumper. The welder comprises two welding gun intermediate connection seats which are arranged on transversely arranged guide rails and driven by screw rods. The screw rods respectively driving the two welding gun intermediate connection seats rotate in opposite directions, and are connected with the same power transmission mechanism. A welding gun mounting frame driven by an oil cylinder is arranged on each of the welding gun intermediate connection seats through a longitudinally arranged guide rail. Two welding guns are arranged on each of the welding gun mounting frames. A fixture table of the automotive door bumper is arranged below the welding guns. Compared with the prior art, the welder can solve the problems of low consistency of a plurality of weld joints of the conventional automotive door bumper and deformation of a welded workpiece.
Description
Technical field
The present invention relates to Machining Technology field, especially a kind of equipment of welding of automotive side door beams.
Background technology
At present, existing a kind of bump-proof rod for automobile door is to be welded in one of its two ends groove that connects supporting plate and to be formed by a round steel pipe.The round steel pipe of this bump-proof rod for automobile door is connected supporting plate weld seam with each piece is positioned at round steel pipe and the both sides that are connected supporting plate groove tower and connect, round steel pipe is connected supporting plate weld seam with two has 4, these 4 weld seams be parallel to each other and every two be symmetrical arranged.In order to guarantee to be accurately installed in use on the setting position of arrangements for automotive doors, the position accuracy demand that the connection supporting plate at this bump-proof rod for automobile door two ends is relative is very high.Existing the welding of 4 of this bump-proof rod for automobile door welding positions everywhere welded, although round steel pipe is located by fixture and fixes with the supporting plate that is connected at two ends before welding, but at 4 welding positions, welded its two ends connection supporting plate of bump-proof rod for automobile door taking out after fixture and had metaboly, their relative positional accuracy can not be guaranteed.By analysis its main cause be after welding round steel pipe be connected the welding uniformity of supporting plate with two poor, stress distribution inequality, in addition, the existing this production efficiency of welding manner is everywhere low, labour intensity is large.
Summary of the invention
Problem to be solved by this invention is to provide a kind of welder for automotive door bumper, to solve the problem that many weld seam uniformity of existing bump-proof rod for automobile door are poor, postwelding workpiece deforms.
In order to address the above problem, technical scheme of the present invention is: this welder for automotive door bumper has Connection Block on two guide rails that are contained in horizontally set and in the middle of the welding gun being driven by screw mandrel, drives respectively in the middle of these two welding guns the screw mandrel rotation direction of Connection Blocks contrary and be connected with same power drive mechanism; Described in each, on the middle Connection Block of welding gun, all the guide rail by longitudinal setting is equipped with the welding gun installing rack by hydraulic oil cylinder driving, and two welding guns are housed on welding gun installing rack described in each; The below of described welding gun is provided with the clamping fixture table of bump-proof rod for automobile door.
In the technical scheme of above-mentioned welder for automotive door bumper, can also be more specifically: described clamping fixture table has a welding bench, and this welding bench is contained on stand by jointed shaft; Described welding bench has upper and lower two installed surfaces, and two supporting plate supporting seats are all housed on each installed surface; Be contained between two supporting plate supporting seats on same described installed surface and be equipped with by hold-down support and be hinged on described welding bench, and connect by cylinder the crimping arm driving; Described in each,, there are three keepers that are contained in respectively on lever arm three of supporting plate supporting seat sides, and described these three lever arms are respectively connected with one and drive cylinder and by jointed shaft, be connected with the hold-down support being connected on welding bench respectively.Described stand is equipped with road wheel, and described in each, supporting plate supporting seat is provided with detent and alignment pin.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, 4 welding guns of this welder for automotive door bumper are contained in respectively by the welding gun installing rack that in the middle of two welding guns, Connection Block connects, in the middle of these two welding guns, the driving screw mandrel rotation direction of Connection Blocks on cross slide way is contrary and be connected with same power drive mechanism, therefore, 4 welding guns can weld simultaneously, and 4 welding guns drive under the drive of Connection Block in the middle of welding gun at screw mandrel, its 4 pads can synchronously move from the middle part of bump-proof rod for automobile door round steel pipe to the two ends of round steel pipe, or synchronously mobile to round steel pipe middle part from bump-proof rod for automobile door round steel pipe two ends, such 4 weld seams make round steel pipe be consistent to a great extent with the welding stress condition that is connected supporting plate of two ends welding, thereby reduce as far as possible the problem of post welding distortion that welding stress produces, in addition, 4 weld seams that obtain symmetrically and evenly, because machinery drives welding gun motion, smooth welded seam degree is also greatly improved.
2, clamping fixture table structure of the present invention is not only protected and has been levied round steel pipe and be connected the accurate location of supporting plate and fixing with two ends, and coordinate and can greatly put forward the efficiency of doing work with welding gun mechanical driving structure, reduced to present 1 minute by original 15 minutes the weld interval that completes a workpiece.
3, this welder for automotive door bumper is compared with original welding procedure, not only greatly reduces operator's labour intensity, and has stopped the generation of substandard product completely.
