Abstract
The invention provides a high-precision rotating table in order to solve the problem that the rotating angle of an existing working table can not be adjusted accurately. The high-precision rotating table comprises a working table body, a supporting disk, a driving shaft and a locating rod, wherein the driving shaft can conduct axial feed and rotate, the driving shaft is fixed to a center disk surface of the working table body, the supporting disk is attached to the working table body and is matched with a driving shaft sliding sleeve, the disk surface of the supporting disk is provided with multiple clamping grooves which are evenly distributed in a circle, one end of the locating rod is fixed to the outer circle of the driving shaft, and the other end of the locating rod can be clamped in one clamping groove.
Description
Technical field
The present invention relates to machine tooling technology, be specifically related to a kind of high-precision rotary working-table.
Background technology
in the processing of component of machine, often need to carry out the operation such as groove milling or boring in different angles to workpiece, and regulate the mode of machining angle to have three kinds at present, the first is the angle of alignment jig, the second regulates machining tool, as the angle of milling cutter or drill bit, the third is that the angle of adjusting operating platform is to realize the processing of workpiece different angles, the first and the second regulative mode often make the structure of fixture or machining tool more complicated, increase cost, and the third regulative mode is comparatively economical, but existing universal rotary workbench adopts turbine and worm mechanism as rotary motive power usually, in the end of worm screw, handwheel is set, the angle of manual adjustments rotary table, there is the problem of degree of regulation difference, affect the crudy of workpiece.
Summary of the invention
The invention provides a kind of high-precision rotary working-table, can not the problem of fine adjustment angle of revolution to solve work on hand platform.
The present invention program is as follows: high-precision rotary working-table, comprise workbench body, supporting disk, driving shaft and backstay, driving shaft can axial feed rotating, driving shaft and workbench body center card are fixed, supporting disk and workbench body are fitted and are arranged and coordinate with driving shaft sliding sleeve, the card of supporting disk is provided with the uniform multiple draw-in grooves of a circle, and one end of backstay is fixed on the cylindrical of driving shaft, and the other end of backstay can be fastened in draw-in groove.
Operation principle of the present invention is as follows: when needing the angle of revolution of adjusting operating platform body, make driving shaft axial feed, backstay is driven first to depart from draw-in groove, then drive shaft turns drives backstay to rotate along the card between two draw-in grooves, snap in this draw-in groove until forward adjacent draw-in groove place to, in the process, because workbench body and driving shaft are fixing, therefore driving shaft can drive workbench body to turn round identical angle simultaneously.The coordinating of backstay and draw-in groove in this programme, the position after workbench body is turned round is more stable.
Because the pivotal angle of this programme workbench body is equal with the central angle of adjacent two draw-in grooves, and draw-in groove is distributed in the card of supporting disk, therefore can guarantee the pivotal precision of workbench body.
Further, driving shaft is connected with the piston rod of a cylinder, is provided with helical guide groove, the inwall of described cylinder is provided with alignment pin in described piston rod border, and the end of described alignment pin is positioned at described helical guide groove.Cylinder drives driving shaft as power, and structure is simpler, and cost is low.
Further, be provided with scale at the cylindrical of described supporting disk, all corresponding scale of each draw-in groove.Supporting disk arranges scale, and draw-in groove is corresponding with described scale, can judges more intuitively as required and the angle of revolution of adjusting operating platform.
Further, in order to be more convenient for, backstay rotates along the card between two adjacent draw-in grooves, and the card between adjacent two draw-in grooves is the inclined-plane that homonymy tilts.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-precision rotary working-table embodiment of the present invention;
Fig. 2 is the structural representation of air cylinder during Fig. 1 implements.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
High-precision rotary working-table as shown in Figure 1, comprise workbench body 1, supporting disk 2, driving shaft 3 and backstay 4, driving shaft 3 can axial feed rotating, and driving shaft 3 can by driven by servomotor, also can be driven by cylinder 6, in order to make structure simple, cost-saving, as shown in Figure 2, in the present embodiment, driving shaft 3 is connected with the piston rod of cylinder 6, be provided with helical guide groove 8 in piston rod border, the inwall of described cylinder 6 is provided with alignment pin 7, the end of described alignment pin 7 is positioned at helical guide groove 8.Helical guide groove 8 coordinates with alignment pin 7, makes cylinder 6 piston rod when moving, existing axially-movable, again rotatably.
Driving shaft 3 and workbench body 1 center card are fixed, supporting disk 2 and workbench body 1 are fitted and are arranged and coordinate with driving shaft 3 sliding sleeve, the card of supporting disk 2 is provided with eight uniform draw-in grooves 5 of a circle, card between adjacent two draw-in grooves 5 is the inclined-plane that homonymy tilts, the cylindrical of supporting disk 2 is provided with scale, the all corresponding scale of each draw-in groove 5, one end of backstay 4 is fixed on the cylindrical of driving shaft 3, and the other end of backstay 4 can be fastened in draw-in groove 5.
When needing the angle of revolution of adjusting operating platform body 1, cylinder 6 piston rod drives driving shaft 3 axially first feeding, i.e. first axially-movable, backstay 4 and draw-in groove 5 are departed from, then driving shaft 3 rotates and drives backstay 4 to rotate along the card between two draw-in grooves 5, snaps in this draw-in groove 5, in the process until forward adjacent draw-in groove 5 place to, because workbench body 1 and driving shaft 3 are fixing, therefore driving shaft 3 can drive workbench body 1 to turn round identical angle simultaneously.
