Description
Technical field
The present invention relates to a kind of individual gears gap-eliminating structures, belong to numerical control machine tool technique field.
Background technique
The vertical axis transmission of digital control plane milling and boring machine is generally driven using lead screw, if vertical axis stroke distances are long, driving
Load weight is big, and the lead screw diameter accordingly selected becomes larger, and influences spatial arrangement structure.If the lathe of high-speed cruising, in order to reach
To good dynamic characteristic, the type selecting of motor also can accordingly become larger, and double-motor anti-backlash infrastructure cost is used to increase, for above-mentioned
Suddenly a kind of Novel transmission to be developed disappears gap mode reason.
Summary of the invention
It is a kind of applied to vertical axis the technical problem to be solved by the present invention is in view of the defects existing in the prior art, provide
In conjunction with the individual gears gap-eliminating structure of counterpoise mechanism.
In order to solve this technical problem, it the present invention provides a kind of individual gears gap-eliminating structure, including gear, retarder, watches
Motor, rack gear and driven object body are taken, the output end of the servo motor and the input terminal of retarder connect, and the gear passes through
Key is fixed on the output end of retarder, and rack gear is fixed on driven object body, and wheel and rack engagement, servo motor passes through deceleration
Device band moving gear rotates, and reaches rack-and-pinion in conjunction with servo motor using driven object body self gravity in vertical direction and passes
The dynamic gap that disappears.
Balancing device is set on the driven object body.
The balancing device is accumulator.
The utility model has the advantages that the present invention is combined using gravity with servo motor in vertical direction, reach rack pinion
The gap that disappears application；Design structure of the present invention is compact, not by travel limit, and debugging is simple, and purchase cost and use cost are substantially reduced.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the structural schematic diagram of the embodiment of the present invention.
In figure: 1 gear, 2 retarders, 3 servo motors, 4 rack gears, 5 driven object bodies, 6 balancing devices.
Specific embodiment
The present invention will now be described in detail with reference to the accompanying drawings and examples.
Fig. 1 show structural schematic diagram of the invention.
The present invention provides a kind of individual gears gap-eliminating structure, including gear 1, retarder 2, servo motor 3, rack gear 4, driven
Animal body 5, balancing device 6.
The output end of the servo motor 3 is connect with the input terminal of retarder 2, and the gear 1 is fixed on deceleration by key
The output end of device 2, rack gear 4 are fixed on driven object body 5, and gear 1 is engaged with rack gear 4.
The servo motor 3 is rotated by retarder 2 with moving gear 1, utilizes driven object body itself in vertical direction
Gravity is combined with servo motor 3 to be reached the transmission of 1 rack gear 4 of gear and disappears gap.This disappears in gap mode, in vertical direction driven object body
Weight is greater than the certain numerical value of upward resultant force when lathe work.
Fig. 2 show the structural schematic diagram of the embodiment of the present invention.
If when bigger according to 3 parameter of servo motor that the weight of driven object body 5 and acceleration of motion are chosen, Ke Yikao
Consider and utilizes 6 balance portion driven object body of balancing device, 5 weight；The balancing device 6 is arranged on driven object body 5, balance
Device 6 is accumulator.
The present invention according to 5 mass of driven object body, can consider power of the driven object body 5 in lifting process composition and at
This accounting, calculating determine the need for configuration balancing device 6.
The present invention is to be combined to reach 1 tooth of gear in vertical direction with servo motor 3 using 5 self gravity of driven object body
Item 4 is driven the gap effect that disappears.If 3 parameter of servo motor chosen according to the weight of driven object body 5 and acceleration of motion is bigger
When, it may be considered that utilize 6 balance portion driven object body of balancing device, 5 weight.In vertical direction driven object body weight or
Weight after balancing device effect is greater than the certain numerical value of upward resultant force when lathe work.In the composition of vertical forces
Generally have frictional force, driven object weight power, cutting force, servo motor driving force, equilibrant force, the above power vertical direction according to
The motion state of object constitutes balance.The equilibrant force of balancing gravity mechanism is traditionally arranged to be no more than 5 weight of driven object body
60%.
The course of work of the invention:
Be ready work first when implementing: 1 rack gear 4 of gear is coupled, and applies lubricating grease；If there is balancing gravity machine
The balancing device adjustment of structure sets this mechanism, balancing device generally using accumulator come 5 weight of balance portion driven object body,
First by the gas of accumulator preliminary filling certain volume and pressure, to reach the moiety by weight of balance driven object body；It powers on, servo electricity
Machine adds enabled, and driven object body 5 is engaged with rack gear 4 with moving gear 1 and moved up and down by retarder 2 under the driving of motor 3:
When moving upwards, motor 3 overcomes gravity and other downward outer power drive objects 5 to move upwards；When moving downward, motor effect
Power reduce but driving direction it is constant, driven object body 5 overcome under self gravitation effect servo motor 3 driving force and other to
On external force move downward.Gear and rack gear remain that side is engaged during the motion.
The present invention is combined using gravity with servo motor in vertical direction, is reached rack pinion and is disappeared gap application.
Design structure of the present invention is compact, not by travel limit, and debugging is simple, and purchase cost and use cost are substantially reduced.
The embodiment above of the present invention, is merely illustrative, be not it is only, it is all within the scope of the present invention or it is equivalent this
Change in the range of invention is surrounded by the present invention.
