Description
Technical field
The invention belongs to stretching-machine technical field, especially relate to a kind of stretcher jaw clamping device.
Background technology
Strip stretching-machine is one of key equipment producing Aero-Space high-performance sheet material, is specifically designed to aluminum and aluminium alloy plate
The tension straingtening technique of material, by sheet material is curved aligning and strength stretching, to eliminate the internal stress of sheet material, improves straight
Degree, it is thus achieved that high-quality, high performance prestretched aluminium sheet.Stretching-machine Levelling principle is to utilize jaw to bite the two ends of sheet metal also
Impose enough pulling force, make sheet material produce plastic elongation deformation so that it is the uneven in length fibre length of draw direction tends to basic
After equal, return to steady statue with equal spring-go amount when laying down external force, reach the purpose of tension straingtening.Sheet material enters jaw
Afterwards, jaw stretching after clamping, be the necessary step of stretched operation, therefore, reliability and the persistence of clamping seem
Particularly important.Traditional clamping device structure is complicated, and manufacture difficulty is big, is difficult to change, and by long-term use easily at clamp
Groove piles up a large amount of aluminum bits, makes whole device lose the effect of clamping.
Summary of the invention
For solving the problems referred to above, it is an object of the invention to provide a kind of simple in construction, the stretcher jaw that using effect is good
Clamping device, it can effectively realize the clamping of sheet material.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of stretcher jaw clamping device, it includes the upper and lower clamp for clamping sheet material, the most solid in upper clamp, lower clamp
Surely having meniscus, meniscus offers groove, dovetail key bottom is placed in described groove and passes through connecting bolt with meniscus
Connecting fixing, the dovetail groove that dovetail key is offered with clamping clinohedral bottom surface central authorities coordinates installation, and clamping clinohedral can be along described
Dovetail key slides；Dental lamina is fixed in clamping clinohedral by position housing piece, and dental lamina is oblique with clamping with position housing piece, dental lamina
Inclined-plane is all used to connect between the body of face.
Further, above-mentioned upper clamp, the clamping clinohedral rear end of lower clamp are provided with isolation damper.
Further, above-mentioned dental lamina is connected by the inclined-plane of band seam with position housing piece.
Further, the angle between above-mentioned dental lamina and position housing piece is 10 °～20 °.
Further, the angle between above-mentioned dental lamina and clamping clinohedral is 10 °～20 °.
Owing to using technical scheme as above, the present invention has a following superiority:
This stretcher jaw clamping device, its simple in construction, easy to use, it is easy to dismantle and keep in repair, it is simple to manufacture and promote the use of,
Meniscus can effectively prevent aluminum bits from piling up with the version of dovetail key, reduces clearing times greatly, is also beneficial to keep away
Exempt from clamp to rub with aluminum bits and produce sliding resistance phenomenon, raise labour productivity；Isolation damper is it can be avoided that broken belt impact causes
Clamp and the damage of other devices, using inclined-plane to be connected between dental lamina with position housing piece can be real with less bolt pretightening
The biggest thrust, effectively avoids position housing piece to receive vibrations and produces and get loose phenomenon, dental lamina and clamping clinohedral it
Between use inclined-plane to connect can effectively to limit the displacement of dental lamina, it is to avoid band clamping inequality.

Detailed description of the invention
With specific embodiment, technical scheme is described in further detail below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, stretcher jaw clamping device of the present invention, it includes the upper and lower clamp for clamping sheet material, on
Being respectively and fixedly provided with meniscus 2 in clamp 1, lower clamp 5, meniscus is fixed on stretching-machine body, and meniscus offers groove 11,
Dovetail key 10 bottom is placed in described groove and is connected by connecting bolt 9 fixing with meniscus, dovetail key and clamping clinohedral 8
The dovetail groove that bottom surface central authorities offer coordinates to be installed, and clamping clinohedral can be slided along described dovetail key；Dental lamina 4 passes through positioning compression
Block 7 is fixed in clamping clinohedral and uses and fastened by attachment screw, dental lamina and position housing piece, dental lamina and clamping clinohedral
Between all use inclined-plane to connect.
Above-mentioned upper clamp 1, the clamping clinohedral rear end of lower clamp 5 are provided with isolation damper 6.
Above-mentioned dental lamina 4 is connected by the inclined-plane of band seam with position housing piece 7.
Angle between above-mentioned dental lamina 4 and position housing piece 7 is 10 °～20 °.
Angle between above-mentioned dental lamina 4 and clamping clinohedral 8 is 10 °～20 °.
After sheet material arrives the position specified, hydraulic cylinder promotes upper clamp 1, the clamping clinohedral 8 of lower clamp 5 by push rod
Dovetail key 10 slides, makes the dental lamina clamping sheet material 3 of clamp 1, lower clamp 5, then realize sheet material is stretched.
The foregoing is only presently preferred embodiments of the present invention, rather than limitation of the present invention, in the essence without departing from the present invention
In the case of god and scope, all equalizations made according to scope of the present invention patent change and modify, and all should belong to the special of the present invention
Within profit protection domain.
