Background technology
At present, domestic military armored vehicle comprises that crawler belt and wheeled mobile vehicle all adopt the van-type structure, and the mounting bracket and the installing hole of transmission and ground-engaging element all are welded on the car body.Because transmission and running gear are higher to each bridge opening relative position and dimension precision requirement, comprise axiality, quality of fit, perpendicularity etc., and large-scale car body all can produce gross distortion when welding, so each bridge opening is carried out the Primary Location except designing large-scale positioning tool, also to leave corresponding allowance to each bridge opening, these allowance must be greater than the welding deformation amount at this position, by the time after the car body welding fabrication, clamp respectively again on the large-sized numerical control machining equipment and each bridge opening to be worked into drawing requirement size.Each big military armored vehicle factory adopts this process to process from the Russia to China.This type of prior art is in the car body welding process, and the car body distortion is serious, singly is that the position distortion of front and back bridge just can reach about 15mm; And process long in time limit, about 16 hours consuming time of the location of every trolley body, the front and back bridge of every trolley body is processed about 40 hours, and all will finish on large-size numerical control machine; Its processing charges is also quite expensive, and the car body locating platform is approximately wanted about 400,000, and every chassis front and back bridge machine adds expense and also reaches 2.8 ten thousand.
Summary of the invention
Be the solution the above-mentioned problems in the prior art, but the utility model a kind of simplified processing process and the high back axle assembly welding frock clamping device of machining accuracy are provided.
The technical scheme that its technical problem that solves the utility model adopts is: it comprises back axle locating shaft 21, round table-like back axle locating shaft seam 22, back axle positioning disk 23 and gland 25, in thick outer end, affixed the inner, the two ends of back axle locating shaft 21 thin trapezoidal round table-like back axle locating shaft seam 22, on back axle locating shaft seam 22, cooperate the thick inner thin trapezoidal round table-like back axle positioning disk 23 in suit outer end, in the outer end of back axle positioning disk 23 gland 25 is installed.Described back axle locating shaft 21 can be circular shaft, also can adopt square shaft or erose d-axis.The outer end of back axle locating shaft seam 22 becomes to closely cooperate with the inner ring of back axle positioning disk 23, and the outer end length of back axle locating shaft seam 22 equals the inner ring thickness of back axle positioning disk 23.Back axle positioning disk 23 the inners become to closely cooperate with the inner ring of back axle ring flange 5.The external diameter of back axle positioning disk 23 outer ends equals the external diameter of back axle ring flange.Be provided with and the corresponding through hole of back axle ring flange 5 screws at back axle positioning disk 23 outer end circumference.Center, two ends at back axle locating shaft seam 22 is respectively arranged with screw, and gland 25 is provided with the through hole that matches with the two ends screw of back axle locating shaft seam 22.
The beneficial effects of the utility model are: it breaks through the constraint of traditional handicraft method, its processing technology no longer needs to adopt large-scale positioning tool anchor clamps, after only the water cutting method is located the position of each bridge opening at the beginning of processing on the side deck is carried out, again each bridge opening is worked into the final size of designing requirement, by adopting some special tooling anchor clamps, make in the car body welding fabrication process clamping all the time and fixing corresponding site, because the frock rigidity is better, can offset the distortion that causes because of welding stress and other factors, therefore behind the car body welding fabrication, the position and the dimensional accuracy of each bridge opening of car body and transmission and ground-engaging element can reach designing requirement, do not need to go up again large-size numerical control machine processing, thereby improved work efficiency, saved cost.It can be widely used in various vehicles particularly in the frame assembly welding procedure of armored vehicle.
