Abstract
The utility model relates to a framework welding modular fixture of unwheeling, it is including dull and stereotyped, longeron clamping device, longeron positioner and crossbeam clamping device, the framework sets up on the flat board, be equipped with longeron positioner on the flat board of the corresponding position of truck longitudinal sill V type seat, be equipped with longeron clamping device on the flat board of longeron both ends position, longeron clamping device presss from both sides longeron both ends tight, be equipped with crossbeam clamping device on the flat board of crossbeam both ends position, utilize the longeron clamping device on the framework welding modular fixture, the longeron of the fixed framework of longeron positioner, utilize the crossbeam of the fixed framework of crossbeam clamping device, thereby guarantee that the relative position of longeron and crossbeam is fixed, through rotatory dull and stereotyped, the welding seam of the horizontal position welding of framework with the longeron, the longeron becomes the downhand welding with the welding seam of V type seat, just so not only can guarantee welding quality but also can guarantee overall dimension, and make welding operation oversimplify.
Description
Technical field
The utility model relates to a kind of framework welding built-up jig of unwheeling.
Background technology
The framework of unwheeling is that the side bearing case designed above by framework is connected with middle underframe, the V-type seat designed below by framework by rubber spring with wheel to being connected, eight bearings of framework are connected with pull bar by every two one group, the porose gusset that the crossbeam of framework designs above is connected with reduction box, this not only requires very high to the apparent size of framework, and framework will have higher fatigue resistance, so strictly welding deformation will be controlled during welding, welding quality will be ensured simultaneously, key position is not only required that magnetic powder inspection is qualified, and requires that ultrasonic examination is qualified.As shown in Figure 1, the framework 5 of unwheeling is welded by two symmetrical longeron 5-1 and the crossbeam 5-2 between two longeron 5-1, the V-type seat 5-3 be positioned at below two longeron 5-1, weld seam has downhand welding, horizontal position welding, vertical position welding, not only framework to be raised when horizontal position welding and vertical position welding and weld, and be difficult to ensure weldquality.
Utility model content
The purpose of this utility model is to overcome above defect, provides one to avoid horizontal position welding and vertical position welding, ensures the framework welding built-up jig of a kind of unwheeling of weldquality and appearance and size.
The technical solution adopted in the utility model is, a kind of framework welding built-up jig of unwheeling, it comprises flat board, longeron clamping device, longeron positioner and machine beam clamping device, framework is arranged on flat board, the flat board of truck longitudinal sill V-type seat correspondence position is provided with longeron positioner, described longeron positioner is made up of V-type seat pattern and longeron pressure strip, the V-type seat of V-type seat pattern and longeron matches, longeron pressure strip compresses longeron above the V-type seat of longeron, the flat board of longeron end positions is provided with longeron clamping device, longeron two ends clamp by longeron clamping device, the flat board of crossbeam end positions is provided with machine beam clamping device, described machine beam clamping device is made up of cross beam support plate and crossbeam pressure strip, crossbeam is placed on cross beam support plate, crossbeam pressure strip compresses crossbeam above cross beam support plate.
Conveniently handling, flat board is provided with hanger.
The beneficial effects of the utility model are: the longeron utilizing the longeron clamping device on framework welding built-up jig, longeron positioner fixed frame, utilize the crossbeam of machine beam clamping device fixed frame, thus ensure that the relative position of longitudinal and cross beam is fixed, pass through Rotating Plates, the weld seam of the weld seam of the horizontal position welding of framework and longeron, longeron and V-type seat is become downhand welding, so just not only can ensure welding quality but also can appearance and size be ensured, and welding operation is simplified.
