Abstract
A negative pressure type workpiece positioning device comprises a base, a seal cover, a suction head, a hollow shaft and a spring. The base is provided with a hollow cavity with an upward opening, the lateral wall of the hollow cavity is provided with a port connected with a negative pressure air source, the hollow shaft is provided with an axial hole, a through hole penetrating through a shaft wall is arranged on the shaft wall, the hollow shaft is vertically fixed at the center of the hollow cavity of the base through a fixing screw, the lower portion of the suction head is provided with a concave hole sleeved on the hollow shaft, the suction head is provided with the ventilating hole communicating the upper face and the concave hole, the spring is sleeved out side the hollow shaft and upwards supports the suction head, and the seal cover is connected with the upper end of the base and fixed on the upper end of the base to press the suction head into the hollow cavity of the base in seal mode. The negative pressure type workpiece positioning device has the advantages of being small in clamping force, stable and accurate in positioning and free of part damage, and is suitable for fine parts with micro volume and workpieces with poor abrasion resistance.
Description
Technical field
The utility model relates to a kind of object positioner, is specifically related to a kind of angrily pressure type Working piece positioning device.
Background technology
As everyone knows, in the manufacture process of product, part processing is generally all accomplished through various device, on equipment, during processing parts, by means of clamping apparatus part to be processed is positioned and fixes usually.Traditional mechanical anchor clamps mostly are applicable to the hard parts with certain surface hardness, certain volume at present; And its limitation is just arranged for the softer tiny workpiece of quality; As if the employing conventional brace problem that piece surface scratches will take place like the plastic lens on the optical lens; And for example, the miniature parts on mobile phone or the clock and watch is if adopt conventional brace to fix defectives such as part deformation will take place.
The utility model content
The utility model technical problem to be solved is; Overcome the deficiency of existing work piece holder; A kind of angrily pressure type Working piece positioning device is provided, it has, and clamping power is little, steady positioning accurately, the advantage of injuring part not, be applicable to fine parts and the relatively poor workpiece of wearability that volume is small.
The technical scheme that the utility model solves its technical problem is:
A kind of angrily pressure type Working piece positioning device, it comprises base, seal cover, suction nozzle, hollow shaft and spring, said base has the cavity of upward opening; Its sidewall is provided with the interface that connects the negative pressure source of the gas, and said hollow shaft is provided with axle center hole, and its axial wall is provided with the through hole that connects axial wall; This hollow shaft is fixed on the central authorities of said base cavity pocket vertically through fixed screw; Said suction nozzle bottom is provided with shrinkage pool and is placed on the hollow shaft, and this suction nozzle is provided with the breeder tube that is communicated with above it with this shrinkage pool, and said spring housing places outside the hollow shaft and upwards supports this suction nozzle; Said seal cover is connected and fixed in the upper end of base, and the suction nozzle envelope is pressed in the cavity of base.
The described angrily pressure type Working piece positioning device of the utility model, the shrinkage pool of its suction nozzle and hollow shaft form sliding fit, and the axle center hole of this hollow shaft lower end is provided with the internal thread that cooperates with fixed screw.
The utility model is connected with the negative pressure source of the gas through the cavity of base; The suction that utilizes negative pressure to produce is adsorbed on workpiece on the locating surface of suction nozzle; Be provided with the spring of cushioning effect simultaneously, thus distortion and the surface damage of having avoided the rigidity clamping force of traditional mechanical formula Working piece positioning device that workpiece is caused.The utlity model has that clamping power is little, steady positioning accurately, the advantage of injuring part not, be applicable to fine parts and the relatively poor workpiece of wearability that volume is small.
Description of drawings
Fig. 1 is the structure chart of the utility model.
The specific embodiment
Combine specific embodiment and accompanying drawing that the utility model is described further at present.
See also the sketch map of Fig. 1 the utility model, diagram angrily pressure type Working piece positioning device comprises base 1, seal cover 2, suction nozzle 3, hollow shaft 6 and spring 7.
Said base 1 has the circular cavity of upward opening, and its sidewall is provided with and connects the negative pressure source of the gas, like air compressor machine, interface 8.Said hollow shaft 6 is provided with axle center hole, and its axial wall is provided with through hole, and this through hole connects axial wall; The axle center hole of these hollow shaft 6 lower ends is provided with the internal thread that cooperates with fixed screw 9, and is fixed on the central authorities of said base 1 cavity vertically through fixed screw 9, and fixed screw 9 also plays the effect of sealing simultaneously.Said suction nozzle 3 is a circular minor axis, and its underpart is provided with shrinkage pool, and this shrinkage pool is placed on the hollow shaft 6, and forms sliding fit with hollow shaft 6; This suction nozzle 3 is provided with the some breeder tubes 5 that are communicated with above it with this shrinkage pool, thereby these some breeder tubes 5 also communicate with the axle center hole of hollow shaft 6.Said spring 7 is placed on outside the hollow shaft 6, and is upwards supporting said suction nozzle 3.Said seal cover 2 is fixed on the upper end of base 1 through Bolt Connection, and suction nozzle 3 envelopes are pressed in the cavity of base 1.
The utility model is described, and angrily the pressure type Working piece positioning device course of work is following: workpiece 4 is placed on the upper surface of suction nozzle 3; The negative pressure source of the gas is air-breathing through 8 beginnings of the interface on the base 1, and air communication is crossed the cavity of base 1, the through hole of hollow shaft 6 and the breeder tube 5 on axle center hole and the suction nozzle 3 and reposefully workpiece 4 held and locatees; The workpiece 4 of 7 pairs of location of spring plays the effect of buffering.The process precision of haveing suffered is high, and absorption is to stablize smooth-goingly, can not scratch piece surface.
Because the utility model adopts air-breathing mode to carry out work, therefore have inhale solid steadily, positioning accuracy is high, to the little advantage of workpiece 4 surface damages of location.The utility model is specially adapted to the thin optical filter of circle or the location clamping of some other tiny metal parts on the mobile lens.
The utility model is not limited in above-mentioned embodiment, and in the scope of the utility model, any non-substantial variations, remodeling, interpolation or the replacement made all should belong to the protection domain of the utility model.
