Abstract

The utility model relates to a floating support pressing device used in the clamp designing process, in particular to a floating support mechanism. The floating support mechanism comprises a base, wherein a linear oil cylinder is fixed at the bottom of the base, an inner taper sleeve is arranged at the position of the base corresponding to the upper portion of the linear oil cylinder and can vertically slide relative to the base under the pushing effect of the linear oil cylinder, a spring is arranged in a taper cavity at the upper portion of the inner taper sleeve, an oblique wedge is arranged on the spring, and a connecting bolt extends into the bottom of the inner taper sleeve. The floating support mechanism is simple in structure, reasonable in design and capable of achieving dual locking and providing powerful and stable supporting force which is mainly hard contact force produced through self locking of a supporting rod and oblique wedge and different from supporting force provided by a standard supporting cylinder through friction force, and the hard contact force is larger and more stable than the friction force.

Description

Over draft support mechanism
Technical field
The utility model relates to the floating support compression device using in jig Design process, specifically a kind of over draft support mechanism.
Background technology
In the time carrying out jig Design, some working position of workpiece need add floating support compression device, although have the pneumatic of standard or hydraulic pressure over draft cylinder now, its structural principle is that the direct locking support bar of tapered sleeve position workpiece provides support power, the support force that this structure provides is limited, the displacement producing while compression again on over draft support structure is larger, is sometimes difficult to meet instructions for use.
Utility model content
The utility model, for the problems referred to above, provides a kind of over draft support mechanism, and this mechanism is dual locking mechanism, and powerful and stable support force can be provided.
According to the technical solution of the utility model: a kind of over draft support mechanism, it is characterized in that: comprise support, described support bottom is fixed with linear oil cylinder, inner cone sleeve is arranged at the upper position place corresponding to linear oil cylinder on support, inner cone sleeve under the promotion of linear oil cylinder relatively support slide up and down, in described inner cone sleeve upper taper cavity, be provided with spring, tiltedly Carve is placed on spring, connecting bolt stretches into from described inner cone sleeve bottom, and the screw portion of described connecting bolt is connected in oblique Carve bottom through spring rear thread, described upper part of the frame is along horizontally set one support bar, and be arranged with back-moving spring on described support bar, be fixed with elastic collet chuck at upper part of the frame corresponding to support bar lower position, described elastic collet chuck bottom outer surface is conical structure.
As further improvement of the utility model, described oblique Carve is arranged to inclined plane shape towards support bar one side in top.
As further improvement of the utility model, described inner conical drogue tube outer surface offers a stopper slot along its length, is fixed with one and is disposed radially stop screw on support, and described stop screw front end stretches in stopper slot.
As further improvement of the utility model, the cone-shaped cavity structure of described inner cone upper cartridge comprises the cylindricality cavity bottom being placed in and is connected in the conical cavity on described cylindricality cavity, and conical cavity openend diameter is greater than conical cavity base diameter.
Technique effect of the present utility model is: the utility model product structure is simple, reasonable in design, can realize double locking, powerful and stable support force is provided, the support force that is mainly reflected in support bar and oblique Carve self-locking and produce is hard contact force, but not the shoring frictionally of image scale standard provides support power, this hard contact force is than large many of frictional force, and much stable; Can realize oblique Carve locking owing to chasing after sleeve in elastic collet chuck, thereby motion is more stable, this mechanism is less demanding to the accuracy of manufacture of each part simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is further described.
In Fig. 1, comprise linear oil cylinder 1, inner cone sleeve 2, connecting bolt 3, spring 4, support 5, oblique Carve 6, elastic collet chuck 7, support bar 8, back-moving spring 9, stopper slot 10 etc.
As shown in Figure 1, the utility model is a kind of over draft support mechanism, comprise support 5, described support 5 bottoms are fixed with linear oil cylinder 1, inner cone sleeve 2 is arranged at the upper position place corresponding to linear oil cylinder 1 on support 5, inner cone sleeve 2 under the promotion of linear oil cylinder 1 relatively support 5 slide up and down, in described inner cone sleeve 2 upper taper cavitys, be provided with spring 4, tiltedly Carve 6 is placed on spring 4, connecting bolt 3 stretches into from described inner cone sleeve 2 bottoms, and the screw portion of described connecting bolt 3 is connected in oblique Carve 6 bottoms through spring 4 rear threads, described support 5 tops are along horizontally set one support bar 8, and be arranged with back-moving spring 9 on described support bar 8, be fixed with elastic collet chuck 7 on support 5 tops corresponding to support bar 8 lower position, described elastic collet chuck 7 bottom outer surfaces are conical structure.
Described oblique Carve is arranged to inclined plane shape towards support bar 8 one sides in 6 tops.
Described inner cone sleeve 2 outer surfaces offer a stopper slot 10 along its length, on support 5, be fixed with one and be disposed radially stop screw, described stop screw front end stretches in stopper slot 10, limits by this structure the extreme position that inner cone sleeve 2 moves up and down.
The cone-shaped cavity structure on described inner cone sleeve 2 tops comprises the cylindricality cavity bottom being placed in and is connected in the conical cavity on described cylindricality cavity, and conical cavity openend diameter is greater than conical cavity base diameter.
Operation principle of the present utility model is as follows: in the time of work, after workpiece is compressed by main clamping platen, linear oil cylinder 1 promotes inner cone sleeve 2, promote oblique Carve 6 by spring 4, then promote support bar 8 by oblique Carve 6, support bar 8 supports to workpiece, inner cone sleeve 2 continues to promote forward, spring 4 is compressed, for support bar 8 provides certain for workpiece contact force, in the time that the inner conical surface of inner cone sleeve 2 contacts with the male cone (strobilus masculinus) of elastic collet chuck 7, under the effect of linear oil cylinder 1, elastic collet chuck 7 is out of shape oblique Carve 6 lockings, because the contact angle of oblique Carve 6 and support bar 8 designs in self-locking angle, even if tiltedly Carve 6 is not by locking, support bar 8 also and tiltedly Carve 6 self-lockings, also can provide powerful rigid support force for workpiece.This mechanism has dual locking function, the support force that particularly support bar 8 produces with oblique Carve 6 self-lockings is hard contact force, but not the shoring frictionally of image scale standard provides support power, this hard contact force is than large many of frictional force, and stable many, if but there is no the oblique Carve 6 of elastic collet chuck 7 locking, workpiece adds and shakes man-hour, tiltedly Carve 6 can be slowly support bar 8 liftings under the effect of spring 4, produce huge jack-up power, by the distortion of workpiece top, the taper locking mechanism of design inner cone sleeve 2 and elastic collet chuck 7 is by oblique Carve 6 lockings, thereby solve this problem.Therefore, this dual locking mechanism is a kind of mechanism that powerful support force and stable support power can be provided.And this mechanism is less demanding to the accuracy of manufacture of each part.
