Description
Technical field
The utility model belongs to Machining Technology field, particularly a kind of quick change chuck at zero point of workpiece quick-replaceable clamping.
Background technology
In mechanical processing process, workpiece is after clamping completes, and usually need by playing table, the means such as gauge head detection determine the dead-center position of workpiece, and operation is numerous and diverse, and processing is long for non-cutting time, and lathe service efficiency is low.For solving problems, reducing processing non-cutting time, investigated the fixture with quick change function at zero point both at home and abroad, effectively can solve the quick-replaceable clamping of workpiece, without the need to again to confirming the zero point of workpiece.But current magic chuck ubiquity positioning precision at zero point is low, and stability in use is poor, take up room the defects such as size is large, the occasion that can not meet the demands higher uses.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of positioning precision high, and stability is strong, and structure is simple, the quick change chuck at zero point that volume is little.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: one quick change chuck at zero point, be made up of pedestal, outer cover body, tension taper pin, mobile, locking spring and clamping steel ball, outer cover body is installed on pedestal, forms an annular cavity with pedestal; Outer cover body has and the center taper hole strained taper pin and match; Tension taper pin is provided with annular slot; Mobile is annular solid, is arranged in described annular cavity, and is provided with locking stage clip between the upper end face and mobile of annular cavity; Pedestal is provided with the air flue acting on mobile lower surface; The inner ring surface of mobile is ramp structure, and the annular forming an adjustable volume with pedestal and outer cover body holds pearl groove, and this annular is held pearl groove and communicated with the center taper hole of outer cover body; Clamping steel ball is placed in annular and holds pearl groove.
Above-mentioned one quick change chuck at zero point, the groove face up and down that described annular holds pearl groove is ramp structure.
Above-mentioned one quick change chuck at zero point, the sidewall of described mobile and annular cavity is provided with gas sealing mechanism.
Above-mentioned one quick change chuck at zero point, described outer cover body is provided with some calibration dowel holes.
Above-mentioned one quick change chuck at zero point, described pedestal is provided with outage.
Compared with prior art, the beneficial effects of the utility model are:
1. mobile adopts integrative-structure, eliminates due to part processing, assembling equal error and the unbalanced coupling mechanism force that causes, avoids the forfeiture of the Locating System Accuracy that steel ball causes owing to wearing and tearing in various degree;
2. rely on mobile's thrust on inclined-plane in process that moves up and down to realize the positioning and locking function of steel ball, steel ball activity space is large, not easily clamping stagnation, and stability is strong;
3. hold the upper and lower groove face of pearl groove and be ramp structure, even if when not putting into tension taper pin, steel ball also can not come off, safe and reliable;
4. hold pearl groove to be jointly made up of mobile and pedestal, space hold size is little, and the overall dimensions being conducive to chuck ensures in less scope;
5. air flue is arranged on pedestal, and vent line can not interfere with the chuck rotated, and can realize 360 degree and rotate processing.
Accompanying drawing explanation
Structural representation when Fig. 1 is the locking of the utility model steel ball.
Fig. 2 is the structural representation of the utility model steel ball when returning.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail.
As shown in Figure 1, one quick change chuck at zero point of the present utility model, is made up of pedestal 1, outer cover body 2, tension taper pin 3, mobile 4, locking stage clip 5 and clamping steel ball 6.Outer cover body 2 is installed on pedestal 1, forms an annular cavity with pedestal 1; Outer cover body 2 has and the center taper hole strained taper pin 3 and match, and the calibration dowel hole 7 matched with auxiliary positioning pin; Tension taper pin 3 is provided with annular slot; Mobile 4 is annular solid, is arranged in annular cavity, and is provided with between the upper end face and mobile 4 of annular cavity and locks stage clip 5; Pedestal 1 is provided with the air flue 8 acting on mobile 4 lower surface, mobile 4 with the sidewall of annular cavity are also provided with gas sealing mechanism 9; The inner ring surface of mobile 4 is ramp structure, and the annular forming an adjustable volume with pedestal 1 and outer cover body 2 holds pearl groove, and the groove face up and down holding pearl groove is inclined-plane, and holds pearl groove and communicate with the center taper hole of outer cover body; Clamping steel ball 6 is placed in annular and holds pearl groove.For preventing the cutting fluid in processing from lodging in chuck, pedestal 1 is also provided with outage 10.
Under the promotion on mobile 4 inner ring inclined-plane, clamping steel ball 6 moves to chuck hub position, blocks tension taper pin 3, locked, tension taper pin 3 is reliably located by the center taper hole on outer cover body 2, does not need to redeterminate zero point, can process workpiece.
When changing workpiece, first in annular cavity, compressed air is passed into by the air flue 8 on pedestal 1, the elastic force that mobile 4 overcomes locking stage clip 5 under the influence of air pressure moves up, the space that annular holds pearl groove constantly becomes large, clamping steel ball 6 glides along groove face under appearance pearl groove and returns under Action of Gravity Field and precompression effect, depart from tension taper pin 3, as shown in Figure 2, now just desirable lower tension taper pin 3 changes workpiece.After workpiece replacing, tension taper pin 3 is reinserted in the center taper hole of outer cover body 2, compressed air in annular cavity is also discharged by closes compression air, mobile 4 moves down in the elastic force effect of locking stage clip 5, under the promotion of mobile 4 inner ring arc surface, clamping steel ball 6 moves to chuck hub position, block tension taper pin 3, locked, tension taper pin 3 is reliably located by the center taper hole on outer cover body 2, in calibration dowel hole 7, insert auxiliary positioning pin simultaneously carry out circumferential registration, do not need to redeterminate zero point, can process workpiece.
The utility model is by the inclined-plane appearance pearl groove structure of variable volume and coordinating of center taper hole, and achieve the quick change clamping at zero point of workpiece, not only positioning precision is high, and operation stability is strong, safe and reliable, and it is little to take volume, applied widely.
Although be described in detail the utility model above, the utility model has been not limited thereto, and those skilled in the art can carry out various amendment according to principle of the present utility model.Therefore, all amendments done according to the utility model principle, all should be understood to fall into protection domain of the present utility model.
