X70 type container flat car crossbeam is formed assembling upset welding tooling
The utility model relates to a kind of welding auxiliary equipment of railway freight-car parts, and especially a kind of X70 type container flat car crossbeam is formed assembling upset welding tooling.
It is one of main group welding piece of X70 type container flat car that the X70 cross bearer is formed; Form by cross bearer web, cross bearer upper cover plate and cross bearer lower cover etc.; Cross bearer is formed assembling quality and is had relatively high expectations, and its assembling needs cross bearer web and both sides, cover plate junction tack welding up and down.The simple frock assembling is adopted in cross bearer assembling before, above a side tack welding more convenient, but opposite side spot welding needs manual work to get into below the frock, faces upward a spot welding, the location is unusual difficulty also, and easy error, production efficiency is very low.
The utility model content
The technical problem that the utility model will solve provides a kind of railway freight X70 type container flat car crossbeam that is used for and forms assembling upset welding tooling; Use this frock can accomplish weld task efficiently; Improve cross bearer assembling welding quality, enhance productivity.
For solving the problems of the technologies described above; The technical scheme that the utility model is taked is: a kind of X70 type container flat car crossbeam is formed assembling upset welding tooling, it is characterized in that comprising the switching mechanism and the fixing framework of switching mechanism, and said switching mechanism is mainly formed groups of holders one-tenth by top; It is the square grid shelf structure that support is formed on said top; Said screen work surface is provided with fixture and positioner, and its two opposite side centerline is welded with turning cylinder, and an end of said turning cylinder is stuck in the shaft coupling; Said shaft coupling is connected with the output shaft of motor through being fixed in the speed-transmitter on the said framework.
Preferably, said framework is made up of bracing frame and Connection Block, and support frame as described above is made up of right bracing frame and left bracing frame, is supported in said turning cylinder two ends through Connection Block respectively.
Preferably, said positioner comprises the locating piece that is distributed in top composition rack frame upper surface, is used to locate, and is distributed in the nail that top is formed support inside casing upper surface, is used to support.
Preferably, said fixture comprises and is arranged at the reservoir that holds out against that support one side frame upper surface is formed on top, and another side upper surface rotatably compress reservoir, the said tailpiece of the piston rod that rotatably compresses reservoir is connected with to rotate to press and grabs.
The operation principle of the utility model: utilize servomotor to drive speed-transmitter, form support and bracing frame etc. through bearing, shaft coupling and turning cylinder, top and connect to form a switching mechanism,, can realize positive and negative turn over function through the control of rotating electric switch; Top is formed support and is provided with the assembling positioning tool that crossbeam is formed, and comprises basic fixed position piece, a nail and holds out against reservoir, can guarantee assembling quality and assembly precision that cross bearer is formed.Form cradle has also increased and has rotatably compressed reservoir on top, prevents that crossbeam from forming in switching process, to fall down.
Adopt the beneficial effect that technique scheme produced to be: the utility model is provided with framework and switching mechanism on underframe is formed; Be used for crossbeam and form the welding between cross bearer median ventral plate, cross bearer upper cover plate and the cross bearer lower cover; Adopt positioner and fixture to cooperate switching mechanism; Make the tack welding welding convenient, improved the assembling welding quality that cross bearer is formed greatly, improved production efficiency.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the vertical view of Fig. 1;
Wherein: the 1-speed-transmitter, the 2-shaft coupling, the 3-crossbeam is formed, the 4-locating piece, 5-props up nail; Support is formed on 6-top, 7-turning cylinder, 8-Connection Block, the right bracing frame of 9-, 10-left side bracing frame; 11-rotatably compresses reservoir, and 12-rotates to press and grabs, and the 13-underframe is formed, and 14-holds out against reservoir.
The specific embodiment
Can know according to accompanying drawing 1 and accompanying drawing 2; The utility model is specifically related to a kind of X70 type container flat car crossbeam and forms assembling upset welding tooling, comprises the switching mechanism and the fixing framework of switching mechanism, and switching mechanism is mainly formed support 6 by top and formed; It is the square grid shelf structure that support 6 is formed on top; The screen work surface is provided with fixture and positioner, and its two opposite side centerline is welded with turning cylinder 7, and an end of turning cylinder 7 is stuck in the shaft coupling 2; Said shaft coupling 2 is connected with the output shaft of motor through being fixed in the speed-transmitter 1 on the said framework.
Framework is made up of bracing frame and Connection Block 8, and bracing frame is made up of with left bracing frame 10 right bracing frame 9, is supported in said turning cylinder 7 two ends through Connection Block 8 respectively, and right bracing frame 9 vertically is fixed in underframe with left bracing frame 10 to be formed on 13.
Positioner comprises the locating piece 4 that is distributed in top composition support 6 frame upper surfaces, is used to locate, and is distributed in the nail 5 that top is formed support 6 inside casing upper surfaces, is used to support.
Fixture comprise be arranged at that top forms support 6 one side frame upper surfaces hold out against reservoir 14, and another side upper surface rotatably compress reservoir 11, the tailpiece of the piston rod that rotatably compresses reservoir 11 is connected with to rotate to press grabs 12.
The concrete method for using of the utility model: at first support 6 is formed up in top, successively cross bearer upper cover plate, cross bearer web and cross bearer lower cover are put on the positioner, hold out against each parts with holding out against reservoir 14; With rotatably compressing reservoir 11 web is compressed, carry out the front tack welding then, start tumbler switch; Make top form frame down; Carry out the opposite side tack welding, accomplish crossbeam and form 3 welding, the frock of overturning at last makes and faces up; Unclamp reservoir 11,14 successively, crossbeam is formed 3 hang in welding sequence.
Crossbeam is formed 3 and is made up of cross bearer web, cross bearer upper cover plate and cross bearer lower cover etc.; Assembling quality is had relatively high expectations; The utility model utilizes inversion principle to make, and has realized upset and welding function in the cross bearer assembling process, has improved welding quality and production efficiency.
When the utility model is formed welding at the X70 cross bearer, in preparation workshop X70 type container flat car is produced in batches, be applied, fully guaranteed the assembling welding quality that cross bearer is formed; Improved production efficiency; Prove through production practices, the frock stable performance, effect is obvious.
