Detailed Description
The technical solution of the present invention will be further described in detail with reference to the drawings.
As shown in FIG. 1, FIG. 2 and FIG. 3, the utility model relates to a vehicle longeron cordwood system hinge combination drilling mould includes bushing plate assembly 1, drill bushing 2, airfoil bushing plate 3, goes up supporting block 4, positioning baffle 6, lower supporting shoe 9, die holder 10, location baffle 11 and locating plate 12.
The 2 airfoil drilling templates 3 are respectively fixed on two sides of one end of the drilling template assembly 1. The positioning baffles 6 are respectively fixed on two side surfaces of the drill plate assembly 1 through bolts, and the positioning baffles 6 on the two side surfaces are in one-to-one correspondence. A plurality of lower support blocks 9 are respectively fixed on the upper surface of the lower template. For supporting the machined part stringer 5.
The positioning plate 12 is fixed on the upper surface of the other end of the lower die holder 10, positioning grooves are formed in two side faces of the upper end of the positioning plate 12, the positioning guide plate 11 is fixed at the other end of the drill plate assembly 1, the positioning guide plate 11 is inserted into the positioning grooves in the outer side face of the positioning plate 12 during installation, and the end portion of a processed workpiece abuts against the positioning grooves in the inner side face of the positioning plate 12 during installation.
The drill plate assembly 1 is provided with a plurality of drill bushings 2. A plurality of upper supporting blocks 4 are fixed on the lower surface of the drill plate assembly 1 and used for pressing the longitudinal beam 5 of the part to be processed.
The drilling template assembly 1 comprises a plurality of drilling templates and a plurality of pairs of hinge connecting plates 7, the drilling templates are in one-to-one butt joint, and the adjacent drilling templates are fixedly connected through the 1 pair of hinge connecting plates 7. 2 hinge webs 7 of the 1 pair of hinge webs 7 are located on either side of the butt end. Two ends of the hinge connecting plate 7 are respectively fixed on the butted 2 drilling templates through connecting pins 8.
Because heavy lorry motorcycle type is various, causes the longeron kind of same width and height, appearance and different wheel base to increase, and this brings very big degree of difficulty for drilling die design, and how to accomplish multiaxis longeron production with minimum module is this utility model's technical difficulty. The method of modular design of the drilling mold is briefly described below by taking the combination of the drilling mold of a common wide-body lathe as an example. The part names corresponding to the serial numbers in fig. 1 are as follows: the drilling template assembly comprises a drilling template assembly 1, a drilling sleeve 2, a wing surface drilling template 3, an upper supporting block 4, a longitudinal beam 5 of a processed part, a positioning baffle 6, a hinge connecting plate 7, a connecting pin 8, a lower supporting block 9 and a lower die holder 10.
In the first embodiment, the combination of the 'longitudinal and lining composite beam' drilling mould building block type hinge structure with the axle base of the 3775+1700/6 x 4 vehicle type is shown schematically. The device consists of a drilling template 5 and a lower die holder 4.
In the second embodiment, the axle base is 4375+1700/6 × 4 model of the building block type hinge structure combination diagram of the drilling mould of the longitudinal and lining composite beam. Consists of 6 drilling templates and 5 lower die seats. The head, the middle and the tail of the drilling machine are added with one drilling module according to the five drilling modules in the figure 2. And four lower die seats are newly added.
Table 1 shows a list of modules used by the longitudinal beam drilling die for two types of vehicle shown in the fourth part:
the above table shows: (1) the wheel base 3775+1700/6 × 4 vehicle model and 4375+1700/6 × 4 vehicle model can share part of the modules.
(2) Compared with a 3775+1700/6 × 4 model module, the model module with the wheel base of 4375+1700/6 × 4 needs to be added with 1-6 and 2-5 modules.
To summarize: the hole pitches of the part drilling modules can be found to be mutually universal by comparing the wheel pitches of the 3775+1700/6 multiplied by 4 vehicle type with the wheel pitches of the 4375+1700/6 multiplied by 4 vehicle type. The wheel base of 4375+ 1700/6X 4 can be produced by putting part of the drilling modules on the basis of the wheel base of 3775+ 1700/6X 4. The input cost of the drilling die is reduced.
