Description
Technical field
The present invention relates to lathe turntable field, especially a kind of large-scale vertical lathe clamping device of rotary table.
Background technology
As everyone knows, at present, the clamping of large-scale vertical lathe turntable generally all adopts built-in oil cylinder, has been come by T-shaped annular groove tension.Because large-scale vertical lathe turntable mesa dimensions is very large, it is very difficult to process annular T-slot, and once processing dimension has deviation, when turntable operates, the T-shaped top on oil cylinder is easy to produce with T-slot rub, and will produce major accident time serious.Clamping device is in the inside of turntable in addition, and installation and debugging are more difficult, once break down, table top must be pulled down by maintenance, brings great inconvenience.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of large-scale vertical lathe clamping device of rotary table, this device not only manufactures easy, stops tightly effective, and outside at turntable, and assembling maintenance is very convenient.
The technical solution adopted for the present invention to solve the technical problems is: a kind of large-scale vertical lathe clamping device of rotary table, be provided with machine body, it is characterized in that above mechanism body, being fixed with lower rotary shaft and upper rotating shaft, upper scissor body and lower scissors body can rotate around upper rotating shaft and lower rotary shaft respectively, machine body is combined with backstay, the end of backstay withstands on outside the head of scissor body, cylinder body is provided with in upper scissor body and lower scissors body afterbody, there is upper piston body cylinder body inside, contacted with upper ball gasket assembly by spacer, a upper ball gasket assembly part is wherein fixed on the tail end of scissor body, cylinder body inside also has lower piston body, maintain an equal level with the upper end of cylinder cap, the lower end of cylinder cap contacts with lower ball gasket assembly, a lower ball gasket assembly wherein part is fixed on the tail end of lower scissors body, stay bolt is from top to bottom successively through spring, upper scissor body, upper ball gasket assembly, upper piston body, lower piston body, cylinder cap, lower ball gasket assembly, lower scissors body also connects into as a whole, upper sense switch is fixed in mechanism body, the contact of upper sense switch is at upper scissor body tail end, lower sense switch is fixed on machine body, the contact of lower sense switch is at lower scissors body tail end.
The invention has the beneficial effects as follows, clamp system is easily manufactured, and has the amplification of power, makes clamping more firm and firm, and clamp system is outside at lathe, and equipment adjustment is easy to maintenance.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is sectional structural map of the present invention.
In figure: 1. backstay, 2. go up scissor body, 3. go up sense switch, 4. spring, 5. go up ball gasket assembly, 6. upper piston body, 7. goes up oil-in, 8. lower piston body, 9. descend oil-in, 10. cylinder body, 11. cylinder caps, 12. times ball gasket assemblies, 13. stay bolts, 14. lower scissors bodies, 15. times sense switches, 16. machine bodies, 17. lower rotary shafts, rotating shaft on 18., 19. mechanism body, 20. turntable rotating parts.
Detailed description of the invention
In FIG, the present invention is provided with mechanism body 19, be fixed with lower rotary shaft 17 and upper rotating shaft 18 above, upper scissor body 2 and lower scissors body 14 can rotate around upper rotating shaft 18 lower rotary shaft 17 respectively, machine body 16 is combined with backstay 1, the end of backstay 1 withstands on outside the head of scissor body 2, and the head of upper scissor body 2 and lower scissors body 14 is when free state because the effect of spring 4 and turntable rotating part 20 leave a small distance, and backstay 1 is size for adjusting this distance.In upper scissor body 2 with lower scissors body 14 afterbody, be provided with cylinder body 10, there is upper piston body 6 cylinder body 10 inside, is contacted with upper ball gasket assembly 5 by spacer, and upper ball gasket assembly 5 part is wherein fixed on the tail end of scissor body 2.Cylinder body 10 inside also has lower piston body 8, and maintain an equal level with the upper end of cylinder cap 11, the lower end of cylinder cap 11 contacts with lower ball gasket assembly 12, and a lower ball gasket assembly 12 wherein part is fixed on the tail end of lower scissors body 14.Stay bolt 13 from top to bottom successively through spring 4, upper scissor body 2, upper ball gasket assembly 5, upper piston body 6, lower piston body 8, cylinder cap 11, lower ball gasket assembly 12, lower scissors body 14, and connects into as a whole.Upper sense switch 3 is fixed in mechanism body 19, and the contact of upper sense switch 3 is at upper scissor body 2 tail end.Lower sense switch 15 is fixed on machine body 16, and the contact of lower sense switch 15 is at lower scissors body 14 tail end.Turntable rotating part 20 is when calibration terminates to need clamping, the hydraulic oil of certain pressure is passed into respectively by the upper oil-in 7 of upper piston body 6 and lower piston body 8 times oil-ins 9, due to the promotion of fluid, upper piston body 6 is made to drive upper ball gasket assembly 12 by the tail end distance that upwards jack-up is certain of upper scissor body 2, lower piston body 8 and then moves up certain distance in addition, this fluid that oil-in 9 enters at present promotes cylinder cap 11 and drives cylinder body 10, lower ball gasket assembly 12 is by distance certain for downward for the tail end of lower scissors body 14 jack-up, because the scissor body two ends arm of force is different, the clamping force of head is amplified due to leverage, thus turntable rotating part 20 clamps by the head of scissor body firmly.The contact of upper sense switch 3 and lower sense switch 15 triggers due to opening of scissor body afterbody, therefore scissor body clamp system can be detected whether working properly, and upper ball gasket assembly 5 and lower ball gasket assembly 12 make lifting surface area increase, decrease the risk that part destroys.
