Abstract
The invention discloses a positioning device of a workpiece. The positioning device of the workpiece comprises a carrier table with a horizontal end surface. A reference block and an auxiliary positioning block are fixed to the carrier table. The reference block is provided with a reference surface perpendicular to the horizontal end surface of the carrier table. The auxiliary positioning block is arranged in the position right facing the reference surface and provided with at least two through holes perpendicular to the reference surface. Each through hole is internally provided with an elastic element and at least one rigid round ball in clearance fit with the through hole. The end, right facing the reference surface, of each through hole is open, and the other end of each through hole is closed. One end of each elastic element abuts against the closed end of the corresponding through hole, and the other end of each elastic element pushes the corresponding round ball along the corresponding through hole. A block portion is arranged at the open end of each through hole. Through the auxiliary positioning mode that the elastic elements are arranged in the multiple sets of through holes to push the rigid round balls, the maintenance cost is reduced, and the positioning accuracy is higher.
Description
Technical field
The present invention relates to the positioner of a kind of workpiece.
Background technology
Increasing along with precision instrument, also increases day by day to the demand of precision parts.Currently for the high-precision product of processing, generally rely on the simple calibration jig of artificial manual engagement, but efficiency is non-normally low.Even if realizing being also required to high cost in efficiency and scrappage.Accordingly, it would be desirable to develop some easy auxiliary device, to improve precision and the efficiency of manual work.
Chinese patent (publication number CN103721908A) provides the manual type heavy duty rotary table that a kind of ball roller guide rod is flexibly positioned, and it includes 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 and stroke can be carried out spacing positioning step, and afterbody is the column type body of rod；The afterbody of spring is provided with female cap formula gland, the pressure of spring can be adjusted by gland by regulating screw.Location rod member positioning end adopts little bulb, adopts cylinder guiding, and add positioning step on rear side of bulb, it is possible to control the location emersion limit of guide post, and spring pressure is adjustable.But solving the precision problem of workpiece location although this technology is a degree of 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；The side of bulb type guide rod and cover for seat contact area are relatively big on the other hand, if non lubricant oil, can cause that spring pressure conduction is not smooth so that in position fixing process, precision is on the low side because spring offer pressure does not wait.
Summary of the invention
The technical problem to be solved in the present invention is to overcome prior art positioning table structure complexity to be not easy to the defect that maintenance, high cost and precision are on the low side, it is provided that the positioner of the workpiece that a kind of precision is higher and lower in cost.
The present invention solves above-mentioned technical problem by following technical proposals:
The positioner of a kind of workpiece, it includes an object stage with horizontal end face, and it is characterized in that, described object stage 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 object stage；
Described auxiliary positioning block be arranged at described datum level just to position；
Being provided with at least two through hole on described auxiliary positioning block, described through hole is perpendicular to described datum level；
A flexible member all it is installed with and the ball of rigidity that at least one and described via clearance coordinates in each described through hole；
Described through hole just one end open to described datum level, the other end is closed；
One end of the closing of the described through hole of described flexible member one end conflict, 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 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, owing to the ball of rigidity is slightly less than and through hole due to diameter, therebetween matched in clearance is belonged to, with the contact area minimum (frictional force is minimum) of the inwall of through hole when ball slides in through hole so that the elastic force of flexible member can be transmitted to greatest extent.Ball is possible not only to slide in through hole, it is also possible to roll so that the serious forgiveness of device is higher.
On the other hand, owing to 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 to change.
It is also preferred that the left between one end of the closing of described flexible member and described through hole, be folded with the ball of another rigidity coordinated with described via clearance.
Herein, arranging the ball of rigidity between flexible member with blind end can make the direction of elastic force of flexible member need to remain consistent with through hole axle center preferably.
It is also preferred that the left one end of the closing of described through hole is to close with a bolt.
It is also preferred that the left the horizontal end face of described object stage is provided with one second reference block, the region beyond passage that described second reference block is arranged on described horizontal end face described datum level and is collectively forming with described auxiliary positioning block.
It is also preferred that the left described receiving part is a boss being located on described opening, described boss surrounds the eck forming a diameter less than described ball.
It is also preferred that the left described bolt to be screwed into the direction of described through hole identical with the direction of the axial line of described through hole, described bolt is provided with the junction surface engaged with torque spanner.
Quantify controlled it is to say, be screwed into, by torque spanner, the degree that bolt can make flexible member tighten, and then improve precision.
The actively progressive effect of the present invention is in that: by adopting the ball arranging flexible member propelling movement rigidity in many group through holes to carry out the mode of auxiliary positioning so that maintenance cost reduces and positioning precision is higher.

Detailed description of the invention
Mode by the examples below further illustrates the present invention, but does not therefore limit the present invention among described scope of embodiments.
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 axonometric chart of the positioner of the workpiece of the present embodiment, Fig. 4 is the Fig. 2 sectional view along A-A, as shown in figures 1-4, the positioner of the workpiece that the present embodiment relates to includes
There is the object stage 1 of horizontal end face, object stage 1 is fixed with reference block 6 and auxiliary positioning block 7, reference block 6 and auxiliary positioning block 7 all one-body molded with object stage 1, and is cube.
Reference block 6 is provided with the datum level 61 vertical with the horizontal end face of object stage 1, auxiliary positioning block 7 be arranged at datum level 61 just to position, and the one side of auxiliary positioning block 7 is parallel with datum level 61.
Being provided with two through holes 71 on auxiliary positioning block 7, through hole 71 is perpendicular to datum level 61.
