Abstract
The invention discloses a thin wall pipe elastic clamping device which comprises a base, wherein a vertical through hole is formed in the base, an elastic sleeve is mounted in the through hole, a sealed cavity is formed between the elastic sleeve and the base, a liquid plastic is arranged in the cavity, a horizontal mounting hole is formed in the base and communicated with the cavity, a plunger in contact with the liquid plastic is arranged in the mounting hole, the tail end of the plunger is fixedly connected with a clamping screw, and the outer diameter of the clamping screw is larger than that of the plunger. The clamping screw abuts against the plunger by rotating the clamping screw, and the liquid plastic is squeezed by the plunger. The liquid plastic transfers force to all directions when squeezed because the liquid plastic is located in the cavity between the elastic sleeve and the base, the elastic sleeve produces uniform axial elastic deformation under the pressure function, a thin wall pipe inserted into the elastic sleeve is clamped, and accordingly, the thin wall pipe is centered and clamped from the outside.
Description
Technical field
The present invention relates to a kind of machining clamp system, be specifically related to a kind of thin-wall pipe elastic clamp device.
Background technology
Fixture adds to be used for rapid fastenings man-hour, makes lathe, cutter, part keep the process unit of correct relative position.Frock clamp is the indispensable parts of machining, machine tool technology at a high speed, efficient, precision, compound, intelligence, environmental protection future development drive under, clamp technology is just towards high-precision, efficient, module, combination, general, economic future development.Jig, is conducive to the machining accuracy, the stabilized product quality that ensure part; Be conducive to raising labour productivity and reducing costs; Be conducive to improving workman's working condition, ensure safety in production; Be conducive to enlarger bed process scope, realize " a tractor serves several purposes ".Fixture is usually by compositions such as setting element (determining the tram of part in fixture), clamping device, tool setting induction element (determine the relative position of cutter and part or guide tool orientation), indexing means (make part can complete the processing of several station in once mounting, have circular index device and rectilinear movement indexing means two class), Connection Element and clamp bodies (clamp base).At present, processing thin-walled part particularly thin-wall pipe time, due to the restriction of part itself, can not clamp from inside, directly very easily cause the damage of part from outside clamping, affect the yield rate of product.Traditional elastic jacket is the outside clamping realized by inclined-plane extruding, due to the angle of inclination on inclined-plane and the length on inclined-plane all limited, chucking power can not be finely tuned in the process of tensioner, cause clamp precision lower, very easily damage thin plate pipe fitting.
Summary of the invention
The object of the present invention is to provide a kind of thin-wall pipe elastic clamp device, by structural improvement, the chucking power in clamping process can be finely tuned, there is higher clamp precision, and thin plate pipe fitting can not be damaged.
For achieving the above object, technical scheme of the present invention is: thin-wall pipe elastic clamp device, comprise base, described base offers vertical through hole, in described through hole, resilient sleeve is installed, Packed cavity is established between described resilient sleeve and base, liquid plastics is provided with in described cavity, described base also offers the installing hole of a level, described installing hole and cavity connects, the plunger contacted with liquid plastics is provided with in described installing hole, the end of described plunger is fixedly connected with a pinching screw, the external diameter of described pinching screw is greater than the external diameter of plunger.
When adopting technique scheme, by rotating pinching screw, pinching screw is made to hold out against plunger, by sliding cylinder extrusion liquid plastics.Because liquid plastics is sealed in the cavity between resilient sleeve and base, when being squeezed, liquid plastics is to all directions transmission of pressure, under the effect of the pressure, resilient sleeve produces uniform elastomeric radial, the thin-wall pipe in resilient sleeve is inserted in clamping, thus makes thin-wall pipe from outside centering clamping.In the present invention, owing to have employed new clamping structure, thin-wall pipe to be held slowly can be clamped equably, the chucking power in clamping process can be finely tuned, there is higher clamp precision, and thin plate pipe fitting can not be damaged.
Further, described resilient sleeve is fixed on base by vertical hold-down screw.This setting, makes hold-down screw can bear the pressure of liquid plastics preferably, plays the effect of sealing.
Further, the opening part of described resilient sleeve is provided with arc enlarging.This setting, adopts arc reaming to increase the area of the opening part of resilient sleeve, can facilitate the insertion of thin-wall pipe to be processed.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of thin-wall pipe elastic clamp device embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, thin-wall pipe elastic clamp device of the present invention, comprises base 1, and base 1 offers vertical through hole, is provided with resilient sleeve 2 in through hole, and resilient sleeve 2 is fixed on base 1 by vertical hold-down screw 21.This setting, makes hold-down screw 21 can bear the pressure of liquid plastics 3 preferably, plays the effect of sealing.Packed cavity is established between resilient sleeve 2 and base 1, liquid plastics 3 is provided with in cavity, base 1 also offers the installing hole of a level, installing hole and cavity connects, the plunger 4 contacted with liquid plastics 3 is provided with in installing hole, the end of plunger 4 is fixedly connected with a pinching screw 5, and the external diameter of pinching screw 5 is greater than the external diameter of plunger 4.The opening part of resilient sleeve 2 is provided with arc enlarging.Adopt arc reaming to increase the area of the opening part of resilient sleeve 2, the insertion of thin-wall pipe 6 to be processed can be facilitated.
In the present invention, by rotating pinching screw 5, making pinching screw 5 hold out against plunger 4, extruding liquid plastics 3 by plunger 4.Because liquid plastics 3 is sealed in the cavity between resilient sleeve 2 and base 1, when being squeezed, liquid plastics 3 is to all directions transmission of pressure, under the effect of the pressure, resilient sleeve 2 produces uniform elastomeric radial, the thin-wall pipe 6 in resilient sleeve 2 is inserted in clamping, thus makes thin-wall pipe 6 from outside centering clamping.Owing to have employed new clamping structure, slowly can clamp equably thin-wall pipe 6 to be held, the chucking power in clamping process can be finely tuned, there is higher clamp precision, and thin plate pipe fitting 6 can not be damaged.
Above-described is only the preferred embodiment of the present invention; should be understood that; for a person skilled in the art; without departing from the inventive concept of the premise; some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.
