Abstract
The utility model relates to a self-adaptive positioning device. A knob is arranged at one end of a bidirectional lead screw, two lead screw nut rods on the bidirectional lead screw are respectively connected with a contact, two ends of the bidirectional lead screw are supported and connected with an end cover through a steel ball, the end cover is fixedly connected with a shell, and one sides of the contacts are respectively provided with a workpiece tray. With the device higher precision and higher efficiency of the self-adaptive property are realize, the accurate positioning of the bidirectional lead screw relative to a pair of contacts is realized by using the principle of synchronous opening and approaching of the bidirectional lead screw, and the accurate positioning of the bidirectional lead screw and the shell is realized by positioning the steel ball, thus realizing the accurate position of a cutter or measuring tool on the shell relative to the pair of contacts. The device can be used for positioning by marking on the blank of a component by a fitter, and used for the self-adaptive positioning of cutters and automatic positioning in technical measurement and the like.
Description
Technical field
The utility model relates to a kind of machining, commercial measurement device, particularly a kind of self adaptation positioner.
Background technology
In machining and commercial measurement, usually need cutter or measurer etc. accurately is positioned a certain feature locations between two surfaces of part, particularly when there is error in the distance on two surfaces of part or changes, still can realize accurately being positioned feature locations.When being positioned the symmetrical centre on two surfaces or departing from a certain definite position of symmetrical centre, be to realize generally speaking by methods such as scale, line or numerical control devices as cutter (or measurer).Its position is mainly determined by operator's naked eyes in scale and line location, and precision and efficient are lower; Numerical control device complex structure cost height.When processing in enormous quantities or commercial measurement, need have high orientation precision, higher location efficiency.Therefore, in machining, commercial measurement field, simple in structure, can have bigger practical value according to the positioner that the size of part is adjusted (self adaptation) automatically.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of self adaptation positioner, utilize opening synchronously and the convergence principle of two-way screw mandrel, satisfy the needs of location such as cutter or measurer in machining and the commercial measurement, positioner has the degree of precision and the greater efficiency of adaptive characteristic.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is: a kind of self adaptation positioner, two-way screw mandrel one end is provided with knob, two feed screw nut's bars on the two-way screw mandrel are connected with contact respectively, the two ends of two-way screw mandrel are connected by steel ball supporting with end cap, and end cap is fixedlyed connected with housing.
Contact one side also is respectively equipped with tray for work pieces.
A kind of self adaptation positioner beneficial effect that the utility model provides is as follows:
1. utilize opening synchronously and the convergence principle of two-way screw mandrel, drive the synchronization-moving characteristics of feed screw nut, the axial location that the symmetrical centre that realizes two contact faces on the feed screw nut is maintained fixed with two-way screw mandrel all the time by two-way screw mandrel.
2, two-way screw mandrel is connected with end cap on the housing by two steel balls, and end cap is fixedlyed connected with housing, thereby has guaranteed the accurate position relation of two-way screw mandrel and housing.
3, housing is consistent all the time in the face of the title center with two contacts, and cutter on the assurance housing or measurer etc. can accurately be positioned symmetrical centre or certain feature locations on two surfaces of interval of uncertainty of part.When size processed or the measurement part changes, still can realize the location quickly and accurately.
Description of drawings
Fig. 1 is the utility model apparatus structure schematic diagram.
The specific embodiment
A kind of self adaptation positioner, two-way screw mandrel 9 one ends are provided with knob 3, two feed screw nut's bars 4 on the two-way screw mandrel 9,4 ' is connected with contact 7 respectively, and 7 ', the two ends of two-way screw mandrel 9 and end cap 1,1 ' connects by steel ball 2 supporting, end cap 1, and 1 ' fixedlys connected with housing 10.
Described contact 7,7 ' one side also is respectively equipped with tray for work pieces 6,6 '.
Embodiment:
Both sides end face with symmetrical turning disk-shaped part 5 is an example, as shown in Figure 1.
After the turning, the center symmetry of the original relatively part 5 of the thickness of part 5, the i.e. identical thickness of the average turning in both sides.When tool setting, require the symmetrical centre of two lathe tools 8,8 ' and the mid-depth of part 5 to overlap, and in batch machining, there is error in the thickness of part 5.
Use the utility model self adaptation positioner, part 5 is by 6, the 6 ' clamping of two pallets, pallet 6, and 6 ' mainly is under the smaller situation of part 5 thickness, is convenient to clamp part 5, is convenient to tool setting.Under the bigger situation of disk-shaped part 5 thickness, can not adopt pallet 6,6 '.
Two lathe tools 8,8 ' are fixed on the housing 10, and housing 10 is connected by steel ball 2 supportings with two-way screw mandrel 9, and therefore two-way screw mandrel 9 relative housings 10 have higher position degree.Rotate the adjustment knob 3 on the two-way screw mandrel 9, Nut pole 4, two contacts 7,7 ' on 4 ' will be opened or convergence synchronously.When contact 7,7 ' when compressing two end faces of part 5, and the symmetrical centre of two-way screw mandrel 9 and housing 10 relative these part thickness has realized accurate location.When the thickness of disk-shaped part 5 changed, as long as contact 7,7 ' compresses two sides of part 5, lathe tool 8 was on the 8 ' feature locations that still can be positioned exactly to be scheduled to.The utility model device can also be by adjusting contact 7, Nut pole 4 on 7 ' the two-way relatively screw mandrel 9,4 ' position, make the position location of cutter (or measurer) adjust to other a certain characteristic point place, as depart from a certain feature locations of thickness symmetrical centre, part 5 thickness all depart from the thickness symmetrical centre by setting value in batch machining, have adaptive characteristic.
Claims (2)
