Abstract
The present invention relates to a clamping mechanism for quickly clamping thin plate pieces, which comprises a bracket, a connecting screw, a connecting plate, a combining screw, a pressing plate and a universal joint bearing, wherein the universal joint bearing is arranged in a hole in the center of the pressing plate; the combining screw penetrates through the center hole of the inner ring of the universal joint bearing, and is combined with the connecting plate; the connecting plate is connected with the bracket through the connecting screw. The present invention has the substantive characteristic that the pressing plate is used as the stress part of the clamping mechanism and is in surface contact with a plate piece to be clamped, namely that the present invention has the characteristic that the stress surface is large. Meanwhile, because the universal joint bearing is arranged in the center hole of the pressing plate, the pressure on the stress surface of the pressing plate is evenly distributed according to the stress characteristic of a spherical surface, and the stress direction of the pressing plate is perpendicular to the surface of the clamped plate piece. When workpieces are slantways placed or have uneven surfaces, the characteristic has large effectiveness.
Description
Technical field
The present invention relates to a kind of quick clamping mechanism, particularly a kind of quick clamping mechanism that is used for holding thin sheet.Be used for mechanical engineering field.
Background technology
Always, the shape of the final application of force part of all kinds of clamp mechanism is block structures, when application such as designing and calculating, usually exerting pressure of block structure application of force part is reduced to a point, abbreviates the point-like head as.In the soldering test practical application, need the thin metallographictest plate of clamping and in the practical application that welding is produced, need clamping metal sheet stamping parts, as use the point-like head, the welding deformation that has only the stress point periphery is controlled, can produce bigger welding deformation at remainder usually.Because foozle, there is certain gradient on the sub-assembly surface of metal sheet and the surface of metal sheet, when carrying out scientific experimentation such as accurate laser weld as these metal sheet material of clamping, require clamp mechanism can adapt to these conditions automatically.
Find through literature search prior art, China Patent No. is: 02108445, name is called: the clamping device of column, the feature readme of this patent is: be to constitute housing by the frame plate with a pair of through hole that can pass column, has the through hole that passes column in this enclosure interior, and the configuration rotational substrate that can along the circumferential direction rotate, be provided with on the position of the circumferencial direction trisection of this rotational substrate three hinged.Though this patent is simple in structure, with low cost, can only be exclusively used in the clamping columnar object, but can not be used for the dull and stereotyped object of clamping.
Summary of the invention
The present invention is directed to the above problem that exists in the prior art, proposed a kind of quick clamping mechanism that is used for holding thin sheet, but big, the stressed evenly tilted-putted sheet metal of self adaptation of stress surface when making its clamping sheet metal or sheet stamping member.
The present invention is achieved by the following technical solutions, the present invention includes: support, attachment screw, connecting plate, closing screw, pressing plate, gimbal suspension bearing.The gimbal suspension bearing is arranged in the hole at pressing plate center, passes the gimbal suspension bearing and puts together on connecting plate closing screw, thereby realize binding between pressing plate and the connecting plate, and the other end and the support of connecting plate link together by attachment screw.
The gimbal suspension bearing comprises: interior ring, outer shroud, closing the centre bore that screw passes interior ring, outer shroud is fixed in the pressing plate centre bore surely by clamp screw.
Support is provided with handle.During work, will approach metallographictest plate or sheet stamping member and be placed on the backing plate, and pull handle on the support then to the dead point, auto lock of the present invention and support apply certain thrust downwards.The thrust of support acts on the gimbal suspension bearing inner ring by connecting plate, in thrust on the ring further act on again on the pressing plate after further passing on the outer shroud, pressing plate is applied to power on thin metallographictest plate or the sheet stamping member as the application of force part of terminal.Because the slab shape of pressing plate, the stress surface that then is held on the part is the plane stress.Because the gimbal suspension bearing transmits the characteristic of power, the power that is applied on thin metallographictest plate or the sheet stamping member is evenly distributed.Be tilted placement as the plate that will weld, the characteristic that the gimbal suspension bearing transmits power can guarantee to be subjected to force direction vertical with plate, the adaptive characteristic of Here it is institute of the present invention tool.
The present invention has substantive distinguishing features, it is that face contacts and just has the big speciality of stress surface with the plate of wanting clamping to pressing plate as the stressed part of clamp mechanism, simultaneously, because in the centre bore of pressing plate, placed the gimbal suspension bearing, according to the spherical loading characteristic, the pressure on its pressing plate stress surface is evenly distributed.Pressing plate is subjected to force direction vertical with the gripping panel surface, and when workpiece tilted placement or surface irregularity, this speciality had very big effectiveness.

The specific embodiment
As shown in Figure 1 and Figure 2: the present invention includes: support 1, attachment screw 2, connecting plate 3, closing screw 4, pressing plate 5, gimbal suspension bearing 6.Gimbal suspension bearing 6 is arranged in the pressing plate 5, passes gimbal suspension bearing 6 and puts together on connecting plate 3 closing screw 4, and connecting plate 3 links together by attachment screw 2 with support 1.
Gimbal suspension bearing 6 comprises: interior ring 7, outer shroud 8, closing the centre bore that screw 4 passes interior ring 7, outer shroud 8 is fixed in the hole at pressing plate 5 centers by holding screw.
