Description
Technical field
The utility model relates to a kind of positioner of workpiece.
Background technology
Increasing along with precision instrument, also increases day by day to the demand of precision parts.At present, for the high-precision product of processing, usually rely on the simple calibration jig of artificial manual engagement, but efficiency is very low.Even if realize also needing high cost in efficiency and scrappage.Therefore, need to develop some easy servicing units, to improve precision and the efficiency of handwork.
Chinese patent (publication number CN103721908A) provides the hand heavy duty rotary table of a kind of ball roller guide rod elasticity location, and it comprises table base, rotary table top, central rotating shaft, support roller, track and elastic positioning device.Its elastic positioning device is made up of cover for seat, guide rod and spring, and guide rod is bulb type guide rod, and its head is provided with bulb, and middle part is provided with can carry out spacing positioning step to stroke, and afterbody is the column type body of rod; The afterbody of spring is provided with female cap formula gland, can be regulated by adjustment screw by the pressure of gland to spring.Location rod member positioning end adopts little bulb, adopts cylinder to lead, and add positioning step on rear side of bulb, can control the location emersion limit of guide post, and spring pressure is adjustable.Though this technology precision problem solving Workpiece fixing to a certain degree but there is following defect: on the one hand, bulb type guide rod structure is similar to piston, complex manufacturing process and be difficult to safeguard, once breakage needs integral replacing; On the other hand the side of bulb type guide rod is comparatively large with cover for seat contact area, if non lubricant oil, spring pressure can be caused to conduct smooth, makes in position fixing process that precision is on the low side because spring provides pressure not etc.
Utility model content
The technical problems to be solved in the utility model be not easy to safeguard to overcome prior art positioning table complex structure, high cost and precision defect on the low side, provide a kind of precision higher and the positioner of the workpiece that cost is lower.
The utility model solves above-mentioned technical problem by following technical proposals:
A positioner for workpiece, it includes the objective table that has horizontal end face, and its feature is, described objective table is fixed with a reference block and an auxiliary positioning block;
Described reference block is provided with a datum level vertical with the horizontal end face of described objective table;
Described auxiliary positioning block is arranged at the just right position of described datum level;
Described auxiliary positioning block is provided with at least two through holes, and described through hole is perpendicular to described datum level;
The ball of the rigidity that a flexible member and at least one and described via clearance coordinate all is installed with in through hole described in each;
Described through hole is just to the one end open of described datum level, and the other end is closed;
Described flexible member one end conflict described through hole close one end, the other end pushes described ball along described through hole;
One end of described via openings is provided with a receiving part, described receiving part be used for described flexible member push described ball until described ball be exposed to described opening outer time, gear connects described ball and makes that described ball is not overall skids off described opening.
That is, because the ball of rigidity is slightly less than and through hole due to diameter, therebetween belong to matched in clearance, when ball slides in through hole and the contact area of the inwall of through hole minimum (frictional force is minimum), the elastic force of flexible member can be transmitted to greatest extent.Ball not only can slide in through hole, can also roll, and makes the serious forgiveness of device higher.
On the other hand, because the manufacture difficulty of ball is far below other ball type device, relative to prior art, its maintenance cost is extremely low.If ball is impaired, only need change.
Preferably, between described flexible member and one end closed of described through hole, the ball of the rigidity that another coordinates with described via clearance is folded with.
Herein, the ball arranging rigidity between flexible member with blind end can make the direction of the elastic force of flexible member need to remain consistent with through hole axle center preferably.
Preferably, one end closed of described through hole closes with a bolt.
Preferably, the horizontal end face of described objective table is provided with one second reference block, described second reference block is arranged at the region beyond passage that on described horizontal end face, described datum level and described auxiliary positioning block are formed jointly.
Preferably, described receiving part is a boss being located on described opening, and described boss surrounds the eck that formation one diameter is less than described ball.
Preferably, the direction that described bolt is screwed into described through hole is identical with the direction of the axial line of described through hole, described bolt is provided with the junction surface engaged with torque spanner.
That is, be screwed into by torque spanner the degree that bolt can make flexible member tighten and quantize controlled, and then improve precision.
Positive progressive effect of the present utility model is: arrange by adopting in many group through holes the mode that ball that flexible member pushes rigidity carrys out auxiliary positioning, maintenance cost is reduced and positioning precision is higher.

Detailed description of the invention
Lift preferred embodiment below, and come by reference to the accompanying drawings clearlyer intactly the utility model to be described.
Fig. 1 is the explosive view of the positioner of the workpiece of the present embodiment, Fig. 2 is the top view of the positioner of the workpiece of the present embodiment, Fig. 3 is the stereogram of the positioner of the workpiece of the present embodiment, Fig. 4 is the sectional view of Fig. 2 along A-A, as shown in figures 1-4, the positioner of workpiece that the present embodiment relates to includes
Have the objective table 1 of horizontal end face, objective table 1 is fixed with reference block 6 and auxiliary positioning block 7, reference block 6 and auxiliary positioning block 7 are all one-body molded with objective table 1, and are cube.
Reference block 6 is provided with the datum level 61 vertical with the horizontal end face of objective table 1, auxiliary positioning block 7 is arranged at the just right position of datum level 61, and a side of auxiliary positioning block 7 is parallel with datum level 61.
Auxiliary positioning block 7 is provided with two through holes 71, through hole 71 is perpendicular to datum level 61.
All be installed with in through hole 71 spring 3 and with the ball 2 of through hole 71 matched in clearance and ball 4.Through hole 71, just to the one end open of datum level 61, the inwall of the other end is provided with internal thread, and bolt 5 is bolted in this internal thread and closes this one end.
Spring 3 one end across ball 4 conflict through hole 71 close one end, the other end pushes ball 2 along through hole 71.
One end of through hole 71 opening is provided with a receiving part, receiving part is used for pushing ball 2 until when ball 2 is exposed to outside opening at spring 3, gear connects ball 2 and makes that ball 2 is not overall skids off opening, and receiving part is a boss being located on opening, and boss surrounds the eck that formation one diameter is less than ball 2.
