Abstract
Framework welds anti-deformation strut bar, it is related to rail vehicle and newly makes system, anti-deformation strut bar is welded more particularly to a kind of framework, deformed after solving existing framework welding, cause two curb girders of framework to distort, shrink or expand, wasted time and energy in the presence of adjustment, difficulty is very big, the problems such as causing Ben Gao and complex operation, poor universality, including strut bar beam, strut bar screw rod, activity top, fixed top, left connection board and right connection board while weld jig is set up be present；Welded successively with right connection board and fixed top one end of the strut bar beam, the other end of strut bar beam opens up internal thread hole, the internal thread hole is connected with the threaded one end of the strut bar screw rod, and the other end of the strut bar screw rod heads into movable top, and the left connection board is welded with activity top.Strut bar, take up space small, it is mobile flexible, it ensure that accessibility during framework welding；Before and after welding, dress takes conveniently, saves the time, the operating efficiency of great lifting operation person.
Description
Technical field
It the utility model is related to rail vehicle and newly make system, and in particular to a kind of framework welds anti-deformation strut bar.
Background technology
Bogie is the key position of rail vehicle, directly affects the travel speed and safety of vehicle；Framework is bogie
Important component, the levels of precision of frame size directly affects the assembly precision and work difficulty of bogie and miscellaneous part, enters
And directly affect the workmanship of vehicle.Size in framework between two curb girders is often the size for being most difficult to ensure in framework.
Because when welding curb girder with crossbeam interface weld seam, curb girder is in free state, due to producing welding deformation after welding, can cause
Two curb girders of framework produce distortion, shrink the overproof problem of equidimension；So that constructor is needed after framework welding to two
Curb girder carries out hot adjusting or cool tone is repaiied, to ensure the requirement of product size.This not only takes a substantial amount of time and energy, and imitates
Rate is low, and difficulty adjusting is larger, and the heat tune or cool tone of excessive number can also change the toughness of framework material, the safety to product
Quality brings hidden danger.
The method to the weld industry of framework is that Anti-deformation device is added at frock at present, if being set up in frock
Weld jig, welding deformation is prevented, often increase the manufacturing cost and complex operation of frock；Also the general of the frock can be reduced
Property, cause to waste.
Utility model content
The utility model causes two curb girders of framework to distort to deform after solving the welding of existing framework, shrink or
Expansion, adjustment be present wastes time and energy, and difficulty is very big, exists while weld jig is set up and causes Ben Gao and complex operation, logical
The problems such as with property difference, there is provided a kind of framework welds anti-deformation strut bar.
Framework welds anti-deformation strut bar, including strut bar beam, strut bar screw rod, activity top, fixed top, left connection board and the right side
Connecting plate；One end of the strut bar beam opens up internal thread with right connection board and fixed top welding, the other end of strut bar beam successively
Hole, the internal thread hole are connected with the threaded one end of the strut bar screw rod, and the other end of the strut bar screw rod heads into movable top,
The left connection board is welded with activity top.
The beneficial effects of the utility model：
First, twisting pole screw rod dismantles the branch to strut bar described in the utility model after weld seam cooling after framework welding
Thick stick.Raise labour efficiency, repaiied compared to cool tone and the method for hot adjusting, saved the time of labourer, dismounting is cooled down after welding
The lower pole can ensure size requirement.
2nd, strut bar cost described in the utility model is low, more economical, due to being connected using strut bar screw rod and strut bar beam screw thread
Connect, can adjust its length, the bogie of other models can also be kept universal.
3rd, strut bar described in the utility model, take up space small, it is mobile flexible, it ensure that accessibility during framework welding；Weldering
Before and after connecing, dress takes conveniently, saves the time, the operating efficiency of great lifting operation person.
Brief description of the drawings
Fig. 1 is the structural representation that framework described in the utility model welds anti-deformation strut bar；
Fig. 2 is the fractionation schematic diagram that framework described in the utility model welds anti-deformation strut bar.
In figure：1st, strut bar beam, 2, strut bar screw rod, 3, activity top, 4, fixed top, 5, right connection board, 6, left connection board.
Embodiment
Embodiment one, illustrate present embodiment, framework welding anti-deformation strut bar, by strut bar beam with reference to Fig. 1 and Fig. 2
1st, strut bar screw rod 2, activity top 3, fixed top 4, left connection board 6 and right connection board 5, one end of the strut bar beam 1 and fixation
Top 4 and right connection board 5 are welded and fixed, and the other end of strut bar beam 1 opens screwed hole, are connected with the screw thread of strut bar screw rod 2；By a left side
Connecting plate 6 is welded and fixed with activity top 3.By left connection board 6 and right connection board 5 with after the cap cylinder bolt connection of curb girder, twisting
Strut bar screw rod 2, it is headed into the circular groove of activity top 3 and be engaged.Twisting the dismounting of pole screw rod 2 after weld seam cooling after welding should
Strut bar.
The operation principle of strut bar described in present embodiment：After dynamic, trailer framework group pair (or before welding), by this reality
Framework welding anti-deformation strut bar branch described in mode is applied between the cap cylinder of truck side sill, with bolt by left connection board 6 and right company
The cap cylinder of fishplate bar 5 and curb girder is fixed, fastened.Strut bar screw rod 2 is turned, it is headed into the circular groove of activity top 3, strut bar spiral shell
Bar 2, which heads into, completes fastening work behind activity top 3；After framework group is checked again for size, strut bar beam 1 is set to play two curb girders
It can be welded after to positioning action, after completing all welding, framework is cooled to room temperature, by the strut bar described in present embodiment
Unload.Do not need cool tone repair or hot adjusting in the case of, can also ensure size after the welding of framework；And the strut bar, space is small,
It is mobile flexible, it ensure that accessibility during framework welding；Before and after welding, dress takes conveniently, saves the time, great lifting operation person
Operating efficiency.
The material of framework welding anti-deformation strut bar described in present embodiment is steel plate-Q345.
