Specific embodiment

Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.

As shown in Figs 1-4, the utility model is realized in this way, which includes 1 He of rotary table For fixing the bearing 4 of rotary table 1, it is structurally characterized in that, 1 bottom centre of rotary table is fixed with shaft 2, branch 4 top centers of seat are fixed with the support shaft 3 being rotatably assorted with the shaft 2, are provided with to adjust between shaft 2 and support shaft 3 It relatively rotates the rotation control switch 5 of angle；The utility model is inserted into branch when mounted, by the shaft 2 of rotary table 1 In the support shaft 3 at 4 top of seat, then workpiece to be polished is fixed on rotary table 1, control switch 5 is rotated by operating So that shaft 2 and support shaft 3 are kept fixed state or rotation status, to adapt to the technique needs that workpiece is polished；It is needing to make When entire rotary-grinding workbench holding is relatively fixed, need to only operate rotation control switch 5 can allow rotary table 1 that can not revolve Turn so that the workpiece on rotary table 1 is in settling position, and can adjust the rotation of rotary table 1 as needed Angle so that workpiece completes the polishing of all angles；Entire Working table structure simple and compact, it is easy to operate, it disclosure satisfy that workpiece The technique of polishing needs.

To ensure the convenience of the precision of worktable rotary and operation, the utility model rotates control to its key structure and opens It closes 5 to be designed, as shown in Figure 5 and Figure 6, rotation control switch 5 includes the pair positioned at 2 lower end of shaft to specific implementation structure Turn tooth 501 and the master positioned at 3 upper end of support shaft turns tooth 502, support shaft 3 is interior equipped with pair turns tooth 501 and master turns tooth for controlling The fore-set 503 of 502 engagement cooperations, the fore-set 503 are sequentially connected with regulation handle 504；First, when mounted, under the shaft 2 End is plugged into 3 upper end of support shaft, is so ensured that the axial support force of shaft 2, is shaken to avoid rotary table 1 It is dynamic；After shaft 2 is inserted into support shaft 3, the pair of shaft 2 turns tooth 501 under the effect of gravity and the master of support shaft 3 turns tooth 502 Engagement, so as to which rotary table 1 be avoided to rotate；When needing to adjust 1 rotational angle of rotary table, regulation handle is rotated 504 to drive fore-set 503 to jack up shaft 2, and the pair of shaft 2 is made to turn the master of tooth 501 and support shaft 3 and turns tooth 502 and departs from, so rotation Workbench 1 can rotate freely, but turn to when needing angle, and fore-set 503 is retracted, and so pair turns tooth 501 under the effect of gravity Turn tooth 502 with master to engage again, it is annular tooth that the master, which turns tooth 502 and turns tooth 501 with pair,；It can be significantly improved using tooth engagement The rotational positioning precision of rotary table 1, easy to operate, position flexible adjustment is reliable.

In order to further improve the structural strength of polishing workbench, the utility model is also in rotary table 1 and rotation Workbench 1 and the connection structure of bearing 4 are improved；In the specific implementation, 1 bottom surface of rotary table and support shaft Several evenly arranged reinforcing plates 6 are connected between 3；And in order to improve the anti-rotation under the larger torque of rotary table 1 Turning ability, one end of reinforcing plate 6 can be selectively connected at the outer rim of bearing 4, as shown in Figure 7 and Figure 8, the reinforcing plate 6 One end be rotatably connected on 1 bottom of rotary table, the other end is connected at the outer rim of bearing 4；So in general technique for grinding Under, reinforcing plate 6 is sustainable to be arranged at 1 bottom of rotary table, plays the role of worktable support, and reduces polishing workbench projection Area, it is compact-sized；When intensity of polishing is high, polishing moment loading is big, bearing is connected to after can the outer end of reinforcing plate 6 be rotated At 4 outer rim, so several reinforcing plates 6 can uniformly disperse the turning moment from rotary table 1, improve structural strength And stability.

Simultaneously, 1 upper surface of rotary table is equipped with the /V connecting hole 101 of several emitting shapes arrangement, no Polishing clamping workpiece position can only be adjusted flexibly using /V connecting hole 101, can also be revolved according to where /V connecting hole 101 1 radial location of revolving worktable judges polishing torque, so as to flexibly judge whether to need, using 6 connects bearing 4 of reinforcing plate, so may be used Effectively improve the convenience of operation.
