Abstract
The utility model relates to an interior clamping clamp which comprises a clamping device, a force application device and a resetting device. The clamping device comprises an elastic clamping sleeve which clamps a workpiece from the inner side, and an extrusion sleeve is arranged outside the elastic clamping sleeve; the force application device comprises a force application jacking rod, the force application jacking rod tightly presses the extrusion sleeve through an expanding block, slope faces for extruding three transmission pins respectively are arranged on the expanding block, and the three transmission pins respectively push three clamping jaws to jack the workpiece from the inner side. The force application jacking rod is jacked to push the expanding block, the expanding block extrudes the elastic clamping sleeve through the extrusion sleeve to clamp the elastic clamping sleeve, and accordingly the workpiece is clamped by the elastic clamping sleeve from the inner side. Meanwhile, when the expanding block moves, the slope faces for extruding three transmission pins respectively are arranged on the expanding block to jack the transmission pins out, the three clamping jaws clamp the workpiece from the inner portion through the transmission pins, and accordingly interior clamping of the whole workpiece is completed.
Description
Technical field
The utility model relates to a kind of fixture for processing, is specifically related to a kind of anchor clamps of inner clamps clamping of workpieces.
Background technology
Anchor clamps are used for fixing processing object in the machine-building process, make it to occupy correct position, with the device of accepting construction or detecting.In a broad sense, any operation in technical process is used for installing rapidly, easily and safely the device of workpiece, all can be described as anchor clamps.For example weld jig, inspection jig, assembling jig, jig etc.Wherein jig is the most common, often abbreviates anchor clamps as.On lathe during processing work, for the surface that makes workpiece can reach the drawing regulation size, geometry and with other surperficial specification requirements such as mutual alignment precision, workpiece must be located, clamped before the processing.Some workpiece need clamp internally owing to the particularity of its structure, thereby needs a kind of special inner clamps clamper.
The utility model content
The purpose of this utility model is to provide a kind of inner clamps clamper, solves the problem that workpiece need clamp internally.
For achieving the above object, the technical solution of the utility model is: the inner clamps clamper, comprise clamping device, force application apparatus and resetting means, and described clamping device comprises the elastic jacket of clamping work pieces internally, the outside of described elastic jacket is provided with extruded sleeve; Described force application apparatus comprises an application of force push rod, and application of force push rod compresses extruded sleeve by the piece that expands, and described bloated piece is provided with the inclined-plane that pushes three trundles respectively, and three trundles promote three jaws top tight workpiece internally respectively; Described resetting means comprises elastic jacket back-moving spring and application of force push rod back-moving spring.
When adopting technique scheme, jacking application of force push rod, application of force push rod promotes the piece that expands, and the piece that expands pushes elastic jacket by extruded sleeve, realizes the clamping to elastic jacket, thereby by elastic jacket workpiece is clamped internally.Simultaneously, when bloated piece moves, because the piece that expands is provided with the inclined-plane that pushes three trundles respectively, trundle is ejected, by trundle with three jaws clamping work pieces internally, thereby the inside of having finished whole work-piece clamps.After cancellation was applied to active force on the application of force push rod, under the effect of elastic jacket back-moving spring and application of force push rod back-moving spring, elastic jacket and jaw resetted, and unclamp workpiece, thereby can remove workpiece down like a cork.
Further, in order to guarantee to add man-hour three jaws to the uniform application of force of workpiece, avoid workpiece to be subjected to uneven chucking power and increase mismachining tolerance, described three trundles be 120 ° of uniform, described three jaws also be 120 ° uniform.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model inner clamps clamper embodiment.
The specific embodiment
As shown in Figure 1, the utility model inner clamps clamper comprises clamping device, force application apparatus and resetting means, and described clamping device comprises the elastic jacket 1 of clamping work pieces internally, and the outside of described elastic jacket 1 is provided with extruded sleeve 2; Described force application apparatus comprises an application of force push rod 3, and application of force push rod 3 compresses extruded sleeve 2 by the piece 4 that expands, and described bloated piece 4 is provided with the inclined-plane that pushes three trundles 5 respectively, and three trundles 5 promote three jaws 6 top tight workpiece internally respectively; Described resetting means comprises elastic jacket back-moving spring 7 and application of force push rod back-moving spring 8.
Jacking application of force push rod 3, application of force push rod 3 promotes the piece 4 that expands, and the piece 4 that expands is realized the clamping to elastic jacket 1 by extruded sleeve 2 extruding elastic jackets 1, thereby by elastic jacket 1 workpiece is clamped internally.Simultaneously, when bloated piece 4 moves, because the piece 4 that expands is provided with the inclined-plane that pushes three trundles 5 respectively, trundle 5 is ejected, by trundle 5 with three jaws 6 clamping work pieces internally, thereby the inside of having finished whole work-piece clamps.After cancellation was applied to active force on the application of force push rod 3, under the effect of elastic jacket back-moving spring 7 and application of force push rod back-moving spring 8, elastic jacket 1 and jaw 6 resetted, and unclamp workpiece, thereby can remove workpiece down like a cork.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
Claims (2)
1. the inner clamps clamper comprises clamping device, force application apparatus and resetting means, it is characterized in that, described clamping device comprises the elastic jacket of clamping work pieces internally, and the outside of described elastic jacket is provided with extruded sleeve; Described force application apparatus comprises an application of force push rod, and application of force push rod compresses extruded sleeve by the piece that expands, and described bloated piece is provided with the inclined-plane that pushes three trundles respectively, and three trundles promote three jaws top tight workpiece internally respectively; Described resetting means comprises elastic jacket back-moving spring and application of force push rod back-moving spring.
