Abstract
The utility model discloses a mechanical boosting chuck claw device of a heavy type lathe workbench. The device includes a single leading screw, a chuck claw, and a chuck claw base, as well as a set of gear force amplifier, a gear shaft I and a gear shaft II parallel to the single leading screw are additionally arranged in the back cavity of the chuck claw base, the square head of a rotation end is arranged on the shaft end of the gear shaft I, and a group of secondary reduction gears are arranged between every two of the gear shaft I, gear shaft II and single leading screw. The beneficial effects of the utility model are that the device provided fundamentally solves the problems that the heavy type vertical lathe is unstable in workpiece clamping and low in efficiency under the condition of heavy load and heavy cutting, in addition, through the perfect combination of a traditional boosting machine and a new type mechanical gear boosting mechanism, the device provided can save time, labor, and space, as well as greatly improves the stability of the workpiece clamping and the work efficiency while workers operate the clamping workpieces. The use of the device proves that the stroke of the device is 220mm, the torque can be increased by 10.32 times, a single claw is capable of bearing an axial force of 50T, and the four-claw clamping is capable of bearing a cutting torque of 160kN.m.
Description
Technical field
The utility model relates to a kind of heavy-duty engine lathe workbench mechanical booster chuck jaw device, and this device is suitable for using on the single, double vertical lathe of heavy type.
Background technology
Traditional workbench chuck jaw all is to adopt single lead screw shaft, transmits moment of torsion by the manual arm of force that increases, and the operating process of this chuck jaw is time and effort consuming not only, and does not guarantee on safety, especially its less stable when heavy load cuts.Fast development along with fields such as China's equipment manufacture, naval vessel, military project, nuclear energy, electric power, demand to superduty list double vertical lathe is very big, the thing followed is also more and more higher to the requirement of workpiece device for clamping, and original monofilament thick stick directly transmits the moment of torsion chuck jaw can not satisfy the needs that the superduty lathe holds workpiece far away.At present, want to alleviate operator's labour intensity, strengthen reliability of structure, its effective method is exactly by means of mechanical booster mechanism, and the domestic design of this mechanism is few, the price of imported product is the costliness of considerable scale again, and these have all seriously restricted the performance performance of the heavy single, double vertical lathe of China.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of heavy-duty engine lathe workbench mechanical booster chuck jaw device, and it is time saving and energy saving that this device has operation, the advantage of performance safety and stability.
The technical scheme that the utility model technical solution problem is adopted is: this mechanical booster chuck jaw device comprises traditional screw mechanism of being made up of monofilament thick stick, chuck jaw and chuck jaw seat, be provided with the set of gears force-increasing mechanism in addition, the specific design of gear force-increasing mechanism is to set up two gear shaft I axles parallel with the monofilament thick stick and gear shaft II axle in chuck corpus unguis back cavity, rotation termination square toes are housed on the axle head of gear shaft I axle, one group of two-stage speed-down gear is housed between gear shaft I axle, gear shaft II axle and monofilament thick stick.
The beneficial effects of the utility model are: fundamentally solved heavy vertical lathe heavy load, hold the workpiece instability under the heavy cut situation, an inefficient difficult problem, by of the perfect adaptation of traditional reinforcement machinery with novel mechanical gear force-increasing mechanism, make the workman when operation holds workpiece, can accomplish to save time, laborsaving, save space improves the stability that workpiece holds simultaneously greatly, increases work efficiency.By using proof, the design's stroke: 220mm can increase 10.32 times of moments of torsion, and monodactyle can bear axial force 50T, the cutting moment of torque that the four paws chucking can bear 160kN.m.
The utility model is under the jurisdiction of the great special project of national science and technology " high-grade, digitally controlled machine tools are made equipment with the basis " project, project number: 2009ZX04001-021.
