Description
Technical field
The utility model embodiment relates to welding technology field, particularly relates to a kind of locomotive underframe ventilating duct assembly welding frock.
Background technology
Along with socioeconomic development and progress, increasing to the quantitative requirement of electric locomotive, also require more and more higher to the workmanship of locomotive.Underframe ventilating duct is as one of the important parts of welding of underframe part, be welded on the cover plate of underframe, play the effect of a transition, cooling air enters from side wall filter, by air channel cooling air to be sent in traction electric machine by traction electric machine ventilation blower and enter cooling, be finally discharged in air.Because the steel plate of underframe ventilating duct is thinner, only has 3mm, weld seam is more, and be again welding by both sides, therefore in welding process, deflection is larger, and the flatness of air channel base plate does not meet Production requirement, causes air channel to have very large gap in the process of welding with underframe cover plate, welding difficulty, have impact on the production of lower operation.
Utility model content
The utility model provides a kind of locomotive underframe ventilating duct assembly welding frock, in order to solve defect of the prior art, accurately and rapidly by Workpiece fixing in frock, reduce the deflection in welding process, improve the quality of products.
The utility model embodiment provides a kind of locomotive underframe ventilating duct assembly welding frock, and wherein, described locomotive underframe ventilating duct assembly welding frock comprises: a workbench, and described workbench is welded for the channel-section steel supporting weldment weight by two block plates and centre; Described workbench is also welded with cushion block, locating piece, compactor, top-fastener and hanger.
Wherein, described locating piece is E type locating piece, and the upper plate of described E type locating piece goes out to organize right size greatly than the length of lower plate.
Wherein, described compactor is 2, and described top-fastener is 7.
Wherein, described hanger is 4, is welded on the corner place on assembly welding platform respectively.
Wherein, described workbench front end-plate and support front end-plate be also provided with gusset.
Wherein, the first screw rod, base, briquetting, described first screw rod is located on described base, described briquetting, and is fixed by nut, is welded on two of described workbench.
Wherein, described top-fastener comprises: the second screw rod and the locating piece be arranged on described second screw rod.
The locomotive underframe ventilating duct assembly welding frock that the utility model provides, by the acting in conjunction of top-fastener, compactor and locating piece, air channel can be fixedly clamped quickly and accurately, thus a large amount of time and labour can be saved, avoid in prior art and rely on workman free-hand group couple, greatly improve production efficiency; In addition, because the principle of frock is simple, make also very easy, therefore simple and practical.
Accompanying drawing explanation
The structural representation of the locomotive underframe ventilating duct assembly welding frock that Fig. 1 provides for the utility model embodiment.
Fig. 2 be embodiment illustrated in fig. 1 in the structural representation of compactor.
Fig. 3 be embodiment illustrated in fig. 1 in the structural representation of top-fastener.
Detailed description of the invention
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The structural representation of the locomotive underframe ventilating duct assembly welding frock that Fig. 1 provides for the utility model embodiment, as shown in Figure 1, this locomotive underframe ventilating duct assembly welding frock comprises: a workbench 1, and workbench 1 is welded for the channel-section steel 12 supporting weldment weight by two block plates 11 and centre; Workbench 1 is also welded with cushion block 2, top-fastener 3, compactor 4, locating piece 5 and hanger 6.
The locomotive underframe ventilating duct assembly welding frock that the utility model embodiment provides, by the acting in conjunction of top-fastener 3, compactor 4 and locating piece 5, air channel can be fixedly clamped quickly and accurately, thus a large amount of time and labour can be saved, avoid in prior art and rely on workman free-hand group couple, greatly improve production efficiency; In addition, because the principle of frock is simple, make also very easy, therefore simple and practical.
Further, on above-mentioned basis embodiment illustrated in fig. 1, locating piece 5 is specifically as follows E type locating piece, and the upper plate of E type locating piece goes out to organize right size greatly than the length of lower plate, thus can locate, and having again can the space of welding.By locating piece 5, the depth of parallelism of locomotive underframe ventilating duct assembly welding frock can be ensured.
Further, above-mentioned embodiment illustrated in fig. 1 in, on workbench 1, compactor 4 is 2, and top-fastener 3 is 7.Hanger 6 is 4, is welded on the corner place on workbench 1 respectively.
Further, above-mentioned embodiment illustrated in fig. 1 in, the front end-plate of workbench 1 and support front end-plate and be also provided with gusset.
Fig. 2 be embodiment illustrated in fig. 1 in the structural representation of compactor, as shown in Figure 2, compactor 3 specifically comprises: the first screw rod 31, base 32, briquetting 33, first screw rod 31 are located on base 32, briquetting 33, and be fixed by nut 34, be welded on two of workbench 1.By compactor 3 being welded on two of workbench 1, can deflection in less welding process.
Fig. 3 be embodiment illustrated in fig. 1 in the structural representation of top-fastener, as shown in Figure 3, top-fastener 4 specifically comprises: the second screw rod 41 and the locating piece 42 be arranged on the second screw rod 41.Top-fastener 4 can position air channel riser.
Below in conjunction with Fig. 1, the concrete using method of the utility model embodiment is described in detail: during the assembly welding frock using the utility model to provide, adopt anti-construction from part, first air channel base plate is lifted on this, the bottom surface in air channel is made to abut on the face of cushion block, regulate top-fastener 4, then two pieces, the front and back riser in air channel is fixed, so just can locate two pieces, the front and back riser in air channel.After having located, unclamped by compactor 3, by the plate group pair of plane on air channel, compactor 3 is compressed two of upper surface plate, and then group is to remaining part successively, group is welded after completing.
To sum up, air channel can be fixedly clamped by locomotive underframe ventilating duct assembly welding frock that the utility model provides quickly and accurately, has saved a large amount of time and labour, changes in prior art and relies on workman free-hand group couple, greatly improve production efficiency; In addition, the principle of frock is very simple, makes also very easy, therefore simple and practical.
