Description
Technical field
The invention belongs to trolley coach end underframe upper cover plate milling technology field, and in particular to a kind of trolley coach end underframe
The postwelding leveling of upper cover plate and milling positioning tool.
Background technology
As shown in Figures 1 to 4, trolley coach end underframe includes end underframe upper cover plate 3, end underframe 4, two hitches of lower cover
Mounting seat clamping plate 5, coupler seat installing plate 6 and two hold underframe front end-plate 7, hold and left side is symmetrically offered on underframe lower cover 4
Window frame 4-1 and right side window frame 4-2, line side of the coupler seat installing plate 6 parallel to both left-hand sash 4-1 and right side window frame 4-2
To and be vertically welded on the middle part connecting plate 4-3 of end underframe lower cover 4.Two lower ends of hitch mounting seat clamping plate 5 with end bottom
The upper surface vertical welding of frame lower cover 4 is connected, and hitch mounting seat corresponding with is pressed from both sides respectively at the two ends of coupler seat installing plate 6
Plate 5 vertical is simultaneously welded.Two are held underframe front end-plate 7 to be vertically fixed on the front end for holding underframe lower cover 4.End underframe upper cover plate
The lower surface of 3 first halfs is welded with the upper surface of two hitch mounting seat clamping plates 5 and coupler seat installing plate 6 respectively, its
Surround to form a long and narrow coupler seat installation cavity jointly.
However, according to existing trolley coach end underframe manufacturing process sequentially, end underframe upper cover plate 3 is in last step
Just it is seated at coupler seat installation cavity top and is covered and welded connected, holds left side flap 3-1, the right side flap of underframe upper cover plate 3
The latter half of 3-3 of upper cover plate of 3-2 and end underframe, all the time all in vacant state, causes existing quick clip during group weldering
Pincers positioner is not easy to be supported its three positioning or compresses positioning, so as to cause and two hitch mounting seat clamping plates 5
The weld seam periphery for corresponding to the left side flap 3-1 and right side flap 3-2 of welding respectively produces irregular deformation of unevenness, it is impossible to using single
Hold-down gear or support meanss carry out leveling, therefore cannot meet on the axis of end underframe upper cover plate 3 that milling is multiple respectively
The demand of the follow-up milling operation of process window 3-4.On the other hand, the latter half of 3-3 of upper cover plate is in the hanging shape for lacking support
State, also cannot more cause that milling operation cannot be implemented to testing amount in fact and leveling operation.
The content of the invention
In order to the upper cover plate for solving the left side flap, right side flap and end underframe of existing end underframe upper cover plate is latter half of in a group weldering
During all the time all in vacant state, cause with two hitch mounting seat clamping plates left side flap of corresponding welding and right side respectively
The weld seam periphery of the wing produces irregular deformation of unevenness, it is impossible to carry out leveling using single hold-down gear or support meanss.Together
When, the latter half of vacant state in support is lacked of upper cover plate, also cannot to testing amount in fact and leveling operation, its flatness without
The method technical problem for causing follow-up milling operation to implement up to standard, the present invention provides a kind of trolley coach end underframe upper cover plate

When the postwelding leveling of concrete application underframe upper cover plate in trolley coach end of the invention and milling positioning tool, such as Figure 13
With shown in Figure 14, the drawing long of upper cover plate bilateral levelling gear 1 and supporting mechanism are passed through into left-hand sash 4-1 from bottom to top respectively
And end underframe lower cover 4 is seated on the upper surface of end cushion block 1-5-1 and middle part cushion block 1-4.Then, respectively by two
Be fixed at the window frame edge of left-hand sash 4-1 by pressed seat 1-5-2, and with same method, using two two pressed seats
Be fixed at the window frame edge of right side window frame 4-2 by 1-5-2.
Hold the lower surface of underframe upper cover plate 3 to be seated in the way of center line is to it to be pacified by coupler seat installing plate 6 and two hitches
The three of dress seat clamping plate 5 surrounds to be formed on a upper surface for long and narrow coupler seat installation cavity jointly, and makes end underframe upper cover plate 3
Left side flap 3-1, right side flap 3-2 are formed respectively from the hanging part of the upper surface arranged on left and right sides of coupler seat installation cavity and rear portion
3-3 latter half of with upper cover plate.Hereafter, observation end underframe upper cover plate 3 is flat with what the upper surface of coupler seat installation cavity fitted respectively
Whole degree, and correspond to pulling seat 1-2-2 under one the first upper cover plate of welding respectively to the larger position in gap both it, it is turned into
Impetus when spending blue bolt to pull downwards.
Upper cover plate middle part levelling gear 2 is arranged in the lower section for holding underframe upper cover plate 3, makes two hitch mounting seat clamping plates 5
End arc section is inserted in a corresponding breach 2-1-1-1 respectively, and makes end underframe upper cover plate left side flap 3-1, right side flap 3-2
And the latter half of 3-3 of upper cover plate is suspended on the top that bottom is fixed on base plate 2-1-1, and it is total to by short adjustable supporting mechanism 2-3
With forming support to it.Additionally, according to the tune of the flatness for holding underframe upper cover plate 3 to be fitted with the upper surface of coupler seat installation cavity
Whole demand is right respectively to flank 3-1, right side flap 3-2 and the larger position of the latter half of 3-3 lower sections deformation of unevenness of upper cover plate respectively
Pulling seat 2-2-2 under second upper cover plate should be welded, it is turned into impetus when spending blue bolt to pull downwards.Then, by
One will length spend the upper/lower terminal of blue bolt 1-2-1 respectively it is long with one spend blue bolt link 1-2-3 and the first upper cover plate under
Pulling seat 1-2-2 link up with, and in the same fashion one by one by each it is short spend blue bolt 2-2-1 with pulling seat under the second upper cover plate
2-2-2 and short blue bolt link 2-2-3 is spent to link up with.
For holding the deformation position that each raises up on underframe upper cover plate 3, can be by corresponding to shortening and its
Length spend blue bolt 1-2-1 or short to spend the overall length of blue bolt 2-2-1 so that the position of convex deformation be able to it is flat downwards
It is multiple.For on end underframe upper cover plate 3 each to lower recess deformation position, then can by extend corresponding to it is short can
The height of supporting mechanism 2-3 or long adjustable supporting mechanisms 1-3 is adjusted, so that the position of concave deformation obtains lifting, so that
The lower surface of left side flap 3-1 and right side flap 3-2 realized with the upper surface of coupler seat installation cavity it is smooth fit, it is met milling
The gap width condition of technique defined.Additionally, the lower surface of the latter half of 3-3 of upper cover plate can also be realized by same method
The adjustment of flatness, so that coincidence measurement and leveling requirements, and reduce to greatest extent because gravity sag factor is to follow-up milling
Influence caused by operation.After the completion of milling operation, pulling seat 1-2-2 and all second under whole and the first upper cover plate of dismantling
Pulling seat 2-2-2 under upper cover plate, and carry out grinding process.
