Description

A kind of edge clamping device of Transparent Parts stretch forming

Technical field

The utility model relates to a kind of edge clamping devices of Transparent Parts stretch forming.

Background technique

Aircraft Canopy Transparencies drawing process is that flat organic glass edge is clamped post-tensioning by clamping plate using cramp frame It stretches, a kind of machine integrated front deck Transparent Parts (containing traditional windscreen and front deck) of coach, when stretch forming, needs quilt The organic glass plate edge of stretching is clamped by two sets of straps using cramp frame, and two sets of strap clampings are intermediate to be needed to reserve The gap of relative movement needs to apply different size on two sets of clamping plates but parallel pulling force to press from both sides under special requirement The poly (methyl methacrylate) plate stress in plate area is different and to relatively move, i.e. generation relative displacement or deformation, this deformation can only allow to have Machine glass plate is deformed along the in-plane of object, does not allow to occur fold, and usual situation is pressed from both sides using common cramp frame grips Plate is due to pulling force it cannot be guaranteed that constantly parallel when stretching flat part to be held, and flat part to be held can be made to stretch Fold occurs under state, cannot achieve the requirement of stretch forming.

Utility model content

The utility model aim is to overcome the deficiencies of the prior art and provide a kind of edge clamping of Transparent Parts stretch forming Device.

The technical problem solved by the utility model is implemented by the following technical solutions:

A kind of edge clamping device of Transparent Parts stretch forming, including cramp frame and match component, the arch Folder includes clamp, screw rod, cramp frame collet and hand lever, and the cramp frame collet includes block-shaped body, in the bottom of block-shaped body Between there is boss, there is groove among the bottom of boss, the bottom of boss is separated to form the clamping heads of two protrusions by groove,

The component that matches includes mating clamping plate and two pieces of clamping clamping plates, and the mating clamping plate is rectangular slab, is matched The height dimension of the thickness and boss that cover clamping plate matches, and there are two slotted holes matched with clamping head for tool on mating clamping plate.

Further, the equivalent width of the width of mating clamping plate and clamping clamping plate, the length of mating clamping plate is according to prearrangement of deformation amount The position on spacing and two clamping heads determines.

The utility model transmits clamping force by cramp frame collet and clamps holing clip to mating clamping plate, then by mating clamping plate Plate, can under the action of flat part to be held is by different stretch power, in retaining surface relative motion without fold and discounting, Large scale multi-curvature Aircraft Canopy Transparencies can be achieved to shape using organic glass plate tension.

Specific embodiment

In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under Face combines and is specifically illustrating, and the utility model is further described.

Embodiment 1, referring to Fig. 1 --- a kind of edge clamping device of Transparent Parts stretch forming shown in fig. 5, including bow Clevis 1 includes clamp, screw rod, cramp frame collet 2 and hand lever, the cramp frame collet with component, the cramp frame 1 is matched 2 include block-shaped body 21, has boss 22 among the bottom of block-shaped body 21, has groove 23 among the bottom of boss 22, recessed The bottom of boss 22 is separated to form the clamping head 24 of two protrusions by slot 23,

The component that matches includes mating clamping plate 3 and two pieces of clamping clamping plates 6, and the mating clamping plate 3 is rectangular slab, The thickness of mating clamping plate 3 and the height dimension of boss 22 match, preferably thickness of the height dimension of boss 22 slightly larger than mating clamping plate 3 Size is spent, there are two slotted holes 4 matched with clamping head 24 for tool on mating clamping plate 3.

Further, the length of the equivalent width of the width of mating clamping plate 3 and clamping clamping plate 6, mating clamping plate 3 becomes according to reserved The position on shape spacing and two clamping heads 24 determines.

When the utility model is used, as shown in figure 4, the upper and lower surface at 5 edge of flat part to be held places clamping respectively Mating clamping plate 3 is placed on the clamping clamping plate 6 on 5 top of flat part to be held by clamping plate 6, by two folders on cramp frame collet 2 It holds head 24 to be clamped on clamping clamping plate 6 across two slotted holes 4 of mating clamping plate 3, rotation hand lever makes under cramp frame collet 2 Pressure grips to clamp the flat part to be held 5 between clamping plates for two pieces, needs to guarantee mating clamping plate 3 slight after clamping It can be up and down under the action of manual force.

The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model Claimed range is defined by the appending claims and its equivalent thereof.
