A kind of accurate positioning device of changing flange head
Technical field the utility model relates to field of machining, particularly a kind of accurate positioning device of changing flange head.
The background technology vehicle driving axle housing is the important bearing part and the driving member of automobile, is the critical component that maintains vehicle operating safety, and the performance of axle housing directly influences the Acceptable life of automobile.Towards the driving axle housing of welding structure have that manufacturing process is simple, stock utilization is high, percent defective is low, productivity ratio is high and advantage such as low cost of manufacture outside, also have enough strength and stiffness, particularly its light weight, but than casting bridge shell safety and reliability.Therefore not only be used for light truck, car, minicar, also replace casting bridge shell gradually, be widely used in various in, heavy truck.
Flange head is applied on the driving axle housing as attaching parts.The processing and forming technology of flange head is complicated, and cost is high, and quality is difficult for grasping; Therefore internal flaw often occurs, if when the inspection eventually of dashing the weldering driving axle housing, find that hole dimension has problem in the flange head, axle housing factory often feels simply helpless; Except that a small amount of workpiece can give way receive, all the other generally are that whole bridge is scrapped and disposed, this has just caused very big waste; Reduce the production efficiency of enterprise, directly influenced economic benefit of enterprises.
The purpose of summary of the invention the utility model provides a kind of accurate positioning device of changing flange head; This positioner is to propose a solution to the problem that exists in the background technology; Have advantages such as structural design is easy, fault rate is low, and result of use is good.
The purpose of the utility model realizes through following technical scheme: a kind of accurate positioning device of changing flange head; It is characterized in that by workbench, working plate, tie-plate, the little slide carriage of lathe, the little slide carriage handwheel of lathe, left socle, angle pin, handwheel, descend positioning seat, trapezoidal screw, last positioning disk, positioning core axle and right support to form; Said tie-plate, the little slide carriage of lathe, the little slide carriage handwheel of lathe, angle pin and positioning core axle; Be two, be separately positioned on the right ends of working plate.
The advantage of this accurate positioning device has: 1, project organization is simple, and is easy to use; 2, enhance productivity, reduce cost.
Description of drawings Fig. 1 is the structural representation of the utility model.
Among the figure, 1, workbench, 2, working plate, 3, tie-plate, 4, the little slide carriage of lathe; 5, left socle, 6, the angle pin, 7, handwheel, 8, positioning seat down, 9, trapezoidal screw; 10, workpiece, 11, go up positioning disk, 12, positioning core axle, 13, right support, 14, the little slide carriage handwheel of lathe.
The specific embodiment is described further the utility model below in conjunction with accompanying drawing and embodiment.
Fig. 1 is the structural representation of the utility model, and in the present embodiment, the both sides of working plate (2) are provided with two tie-plates (3); The little slide carriage of lathe (4), left socle (5), right support (13) and angle pin (6) are installed in respectively on the tie-plate (3) of working plate (2) both sides; After assembling, rotation hand wheel (7), the height of positioning disk in the coarse adjustment (11) is to the height that needs; One qualified axle housing is put into reprocesses on the device; Finely tune the bolt of lower base gap of the little slide carriage of lathe (4), and fine setting trapezoidal screw (9), the flange head end face of axle housing and the end face and device applying seamless back locking of flange observed.
The axle housing that need are reprocessed is put on the last positioning disk (11) of this device; On left socle (5) and right support (13), positioning core axle (12), the little slide carriage handwheel of hand two ends lathe (14) comes feeding to flange head, slowly inserts flange head in the steel pipe with angle pin (6) and bolt; And welding gap joint and axle housing length overall about controlling well; With flange head point solid after, carry out boxing and machine separately and add, successfully reprocess axle case assy thereby realization utilizes this to install.
Through test, adopt this device to put the axle case assy of deciding of reprocessing, success rate 100%.Greatly reduced the product quality cost.
