The specific embodiment
This specific embodiment provides a kind of jib welding tooling, jib welding that it is applicable to different model, can effectively improve welding tooling utilization rate, reduce production costs.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1-Fig. 4, the jib welding tooling that this specific embodiment provides, comprising:
Jig 11;
Be fixedly installed on the fixing support rack 12 of jig 11;
Be fixedly installed on the first tire plate 13 of fixing support rack 12;
Be arranged at the railroad 14 of jig 11;
Be mounted slidably the movable support frame 15 in railroad 14, and be provided with the bracing frame positioner 16 that movable support frame 15 is positioned to railroad 14 between movable support frame 15 and railroad 14;
Be arranged at the installing space that is formed for installing jib 18 to be welded between second fetus plate 17, the first tire plates 13 of movable support frame 15 and second fetus plate 17, the first tire plate 13 and second fetus plate 17 are equipped with for locating the jib positioner 19 of jib 18 to be welded.
So arrange, the two ends of jib 18 to be welded can be positioned respectively the first tire plate 13 and second fetus plate 17 by jib positioner 19, because the first tire plate 13 is fixedly installed on fixing support rack 12, second fetus plate 17 is arranged on movable support frame 15, and movable support frame 15 can slide along railroad 14.
When processing the jib of different model, can be according to the physical length of jib 18 to be welded, adjust movable support frame 15 in the position of railroad 14, until the first tire plate 13 and second fetus plate 17 have suitable distance so that jib 18 to be welded to be installed, then by bracing frame positioner 16, movable support frame 15 is positioned on railroad 14.
Therefore, the jib welding tooling that this specific embodiment provides, can be applicable to the jib of production different model, and frock utilization rate is higher, and production cost is lower.
In order to regulate easily the position of movable support frame 15 on railroad 14, in the preferred version of this specific embodiment, can also comprise the drive unit 20 for driving movable support frame 15 to slide along railroad 14.
So arrange, the driving effect by this drive unit 20 can regulate the position of movable support frame 15 on railroad 14, convenient and strength-saving.It should be noted that, above-mentioned drive unit 20 can be specially hydraulic cylinder, certainly, also can be the drive unit of other type, such as, the drive unit that comprises motor and transmission device, the gearing by transmission device is converted to linear drives power by the rotation of motor, to drive movable support frame 15 to slide along railroad 14.
In addition, in this specific embodiment, the jib positioner 19 that is arranged at the first tire plate 13 and second fetus plate 17 can be specially landing nipple, the first tire plate 13 and second fetus plate 17 are equipped with for the locating slot of this landing nipple is installed, landing nipple can be removably installed in locating slot by bolt, landing nipple is provided with dowel hole, and the joint of jib 18 to be welded positions by being plugged in the pin of jib 18 to be welded and dowel hole.
In this specific embodiment, for movable support frame 15 is positioned at the bracing frame positioner 16 of railroad 14 can comprise be arranged at movable support frame 15 the first pin-and-hole, be arranged at the second pin-and-hole of railroad 14 and can be plugged in the shop bolt of the first pin-and-hole and the second pin-and-hole simultaneously.
When movable support frame 15 slides into after suitable distance along railroad 14, the first pin-and-hole and the second pin-and-hole can align just, by being inserted into the shop bolt of the first pin-and-hole and the second pin-and-hole, can reliably movable support frame 15 be positioned on railroad 14.
In the preferred version of this specific embodiment, also comprise be fixedly installed on jig 11, by the bracing or strutting arrangement 21 of the lower support jib 18 to be welded of jib 18 to be welded.
So arrange, bracing or strutting arrangement 21 is treated welding jib 18 and has been formed supporting role below jib 18 to be welded, makes jib 18 to be welded in welding process, have better stability.
In order to adapt to the welding requirements of the jib of different model, above-mentioned bracing or strutting arrangement 21 is preferably Height Adjustable bracing or strutting arrangement 21, such as, bracing or strutting arrangement 21 can comprise be fixedly installed on the base of jig 11 and by Screw assembly in the support column of base, by regulating the threaded engagement degree of depth of support column and base, the i.e. whole height of adjustable supporting device 21.So arrange, bracing or strutting arrangement 21 can regulate according to the large ting model of jib 18 to be welded, to be applicable to the welding requirements of the jib of multiple different model.
In addition, it should be noted that, due to the jib of different model, its cross section varies in size, therefore the joint location of the jib of different model is different.Given this, in this specific embodiment, the landing nipple that is arranged at the first tire plate 13 and second fetus plate 17 can be many groups, and every group of landing nipple is corresponding to the joint of the jib to be welded 18 of different model.So arrange, the jib of different model also can be positioned on the first tire plate 13 and second fetus plate 17 by landing nipple on the same group not.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
