The specific embodiment

In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.

As shown in Figures 1 to 3, a kind of elasticity automatic positioning clamp providing for the utility model embodiment, it comprises base 1, be located at the jig plate 2 for place work piece on base 1, be located between base 1 and jig plate 2 for workpiece being carried out to the elastic locating mechanism of elasticity location, on jig plate 2, be also provided with for adsorbing the vacuum cup 3 of workpiece, thereby can carry out Dual positioning to workpiece, vacuum cup 3 can be installed on jig plate 2 by locking member (such as bolt etc.).The elasticity automatic positioning clamp that the utility model provides, it carries out elasticity location by elasticity positioning fixture is set to workpiece, vacuum cup absorption workpiece is also set simultaneously to be positioned it, because it is elasticity location, when holding workpiece, there is certain buffering, thereby can avoid workpiece to cause secondary to crush, improve the qualification rate of workpiece.

Further, elastic locating mechanism comprises to the side of workpiece horizontal direction is carried out the transverse elasticity detent mechanism 4 of elasticity location and the side of workpiece longitudinal direction carried out to the longitudinal elasticity detent mechanism 5 of elasticity location, by workpiece being carried out on horizontal direction and longitudinal direction to elasticity location, thereby can make workpiece be located vacuum cup locate failure in the situation that when air pressure is unstable, also can avoid workpiece appearance to be crushed.

Particularly, as shown in Figure 4, transverse elasticity detent mechanism 4 comprises the first cylinder 41, what be fixedly connected with the piston rod 412 of the first cylinder 41 first draws material pin 42, with first draw material pin 42 the first slide blocks 43 that are slidably connected, the first guide rail 44 being slidably matched with the first slide block 43 and be sheathed on the first the first elastomer 45 drawing on material pin 42, first draws the end of material pin 42 to have one first draws plunger 421, first draws the diameter of plunger 421 to be greater than the first diameter that draws the body part of material pin 42, thereby the first elastomer 45 can be held in the first slide block 43 and first and draw between plunger 421, the first slide block 43 tops are provided with for supporting first locating dowel 46 of workpiece so that workpiece is positioned, the first locating dowel 46 is positioned at the side of jig plate 2 and penetrates jig plate 2, thereby the first locating dowel 46 can support that it is positioned to being positioned at the side of the workpiece on jig plate 2, corresponding the first chute 21 of adjusting its position for the first locating dowel 46 that offers on jig plate 2, so that the first locating dowel 46 can be adjusted and support mutually with the side of workpiece horizontal direction according to the size of workpiece size at any time.Particularly, the first chute 21 can be U-shaped chute, the first chute 21 and the first guide rail 44 be arranged in parallel, thereby when the first slide block 43 slides along the first guide rail 44, the first locating dowel 46 can move along the first chute 21, thereby adjust its position workpiece is supported to location, certainly, the first chute 21 also can be kidney-shaped chute, rectangle chute etc.

On the first slide block 43, there is a L shaped adjutage 431, adjutage 431 slips are located at first and are drawn on material pin 42, when thereby adjutage 431 draws material pin 42 to slide along first, can drive the first slide block 43 to slide along guide rail 44, the first elastomer 45 is held in first and draws between plunger 421 and adjutage 431.

Transverse elasticity detent mechanism 4 its courses of work are as follows: open hydraulic control and cut down, piston rod 412 motions of the first cylinder 41, what drive was attached thereto first draws material pin 42 to move, and being held in first, draws between plunger 421 and adjutage 431 on the first elastomer 45, therefore first draws plunger 421 will be forced to compress the first elastomer 45, supporting under reaction force of the first elastomer 45, adjutage 431 will be forced to draw material pin 42 to slide along first, thereby drive the first slide block 43 to slide along the first guide rail 44, thereby the first locating dowel 46 on the first slide block 43 will move thereupon together, the first locating dowel 46 is in mobile process, slowly to the side of workpiece, draw close, thereby it is supported to location, because the first locating dowel 46 is movements under the ordering about of the first elastomer 45, thereby the first locating dowel 46 is elasticity location when workpiece is positioned, certain impact can be born because of it in elasticity location, there is certain buffering effect, thereby it can avoid to workpiece, causing secondary to crush in the process that workpiece is clamped, thereby can improve the qualification rate of workpiece, meet high-quality requirement.

Particularly, above-mentioned the first elastomer 45 can be spring.

The structure of longitudinal elasticity detent mechanism 5 is identical with the structure of transverse elasticity detent mechanism 4, its operation principle and process are also identical with transverse elasticity detent mechanism 4, do not repeat them here, the side of 5 pairs of workpiece longitudinal directions of longitudinal elasticity detent mechanism is supported location, jointly completes the location to workpiece with transverse elasticity detent mechanism 4.

Further, as depicted in figs. 1 and 2, between base 1 and jig plate 2, be also provided with a plate 6, elastic locating mechanism is located between connecting plate 6 and jig plate 2, be that transverse elasticity detent mechanism 4 and longitudinal elasticity detent mechanism 5 are all located between connecting plate 6 and jig plate 2, the two is all fixed on connecting plate 6.

Further, for workpiece can accurately be measured, when measuring, there is measurement environment relatively preferably, between connecting plate 6 and base 1, be also provided with one for workpiece bottom provides the light source board 7 of illumination, so that workpiece peripheral profile is detected.Particularly, light source board 7 can be arranged to shaped as frame, thereby both can save illumination cost, can guarantee that again the periphery of workpiece is irradiated to, and has good measurement illumination, guarantees the accurate of measurement.

Because thering are the parts such as electronic circuit board, diffuser on light source board 7, for avoiding parts on light source board 7 to be connected plate 6 and jig plate 2 damages by pressure, can make between light source board 7 and connecting plate 6 spaced apart, do not contact mutually, side at light source board 7 is provided with support bar 8,8 pairs of connecting plates 6 of support bar support, thereby can be by spaced apart between light source board 7 and connecting plate 6.

These are only preferred embodiment of the present utility model, not in order to limit the utility model, all any modifications of doing within spirit of the present utility model and principle, be equal to and replace or improvement etc., within all should being included in protection domain of the present utility model.
