The utility model is applied to the technical field of aerospace.
Description
Technical Field
The utility model relates to a drilling fixture, in particular to a drilling fixture for a cabin cover of a sports aircraft.
Background
In the past, manufacturers producing light aircraft in China have had few tendency to increase sharply in recent years, but the assembly of the existing light aircraft cockpit covers is to put the whole cockpit cover into a machine body for measurement, debugging, trimming and the like, and after the cockpit cover and the machine body reach the assembly tolerance range, a series of sub-assembly parts in the cockpit cover begin to be marked and punched according to the reference size of the drawing.
The assembly has the disadvantage that the standard for installing the canopy depends on the standard and tolerance of the fuselage, so that the large fuselage assembly has difficulty in ensuring that the size and precision of each assembly standard are consistent, and moreover, the operation of scribing, drilling and the like on the canopy in the fuselage can easily cause pollution and damage to the fuselage assembly.
Disclosure of Invention
The utility model aims to solve the technical problem of overcoming the defects of the prior art and providing the drilling clamp for the cabin cover, which has reasonable design, improves the assembly precision and improves the assembly efficiency.
The technical scheme adopted by the utility model is as follows: the utility model comprises a base wood board and a cabin cover, wherein the base wood board comprises a clamp main body which is processed and molded by a CNC (computer numerical control) processing center, the clamp main body is connected with and fixed with 6 drilling templates, meanwhile, the clamp main body is connected with and fixedly supports a positioning plate, five angle irons are tightly locked at the middle part of the clamp main body by screws, and then the surfaces of a first positioning aluminum block and a second positioning aluminum block are tightly abutted against the two sides of the cabin cover and are tightly locked and fixed by screws.
Further, the supporting and positioning plate is vertically inserted into the insertion opening on the base wood plate, and is tightly stuck and positioned by structural glue.
Further, 5 angle irons are connected end to end and tightly locked on the middle platform part of the base wood board by using a compression screw.
Further, the canopy is placed horizontally on the base plank to ensure that the inner side edge of the canopy is tightly matched with the curved surface on the step milled by the CNC machining center on the clamp main body, and the front edge of the canopy is tightly pressed in the groove right above the supporting and positioning plate.
Furthermore, the 6 drilling templates are vertically inserted into the sockets on the base wood board and are tightly adhered and positioned by structural adhesive.
Further, the side surfaces of the first positioning aluminum block and the second positioning aluminum block are tightly clung to the side surface of the cabin cover, and are tightly pressed and locked by screws.
The beneficial effects of the utility model are as follows: because the positioning drilling fixture is utilized, the cabin covers can be directly placed on the fixture to carry out accurate positioning drilling, sub-assembly parts on each cabin cover are uniform references and can be interchanged, and the cabin covers can be directly placed into the machine body to be fixedly locked only by completing assembly of the cabin covers on the fixture.
