Description
Technical field
The utility model belongs to technical field of mechanical transmission, and in particular to a kind of high precision movement slide unit gear back clearance elimination
Mechanism.
Background technique
Since robot is very high to the mobile required precision in place of robot with industry, so the movement of mounting robot
Slide unit just needs very high positioning accuracy.It is not driven this requires the gear drive of robot Mobile Slide reaches
Backwards to gear clearance.At present the country machining accuracy with developed country in the world machining accuracy there are also a segment difference away from.It is international
The rack pinion pair of the high precision movement slide unit of upper developed country is then directly to process in place by equipment, installs backgear tooth
The engagement of item can be achieved with not backwards to gap.But domestic processing industry is also difficult to accomplish to install after directly processing at present
Out without the rack pinion pair backwards to gap.It is domestic to solve to eliminate method of the rack-and-pinion backwards to gap at present to be with one
Sleeve spring relocation mechanism come compensate rack pinion backwards to gap.The shortcomings that this sleeve spring mechanism be spring by long-term use
Can disappear a part of elastic force, to cause to eliminate the unstable situation in gap.Since spring itself has certain elasticity, work as equipment
Huge inertia force will make gear and rack teeth mechanism slippage phenomenon occur when emergency stop.Once there is slippage phenomenon, Mobile Slide is determined
Position precision will have no to ensure, and the program that robot writes also will all scrap to need to rewrite.
Utility model content
The purpose of this utility model is to solve the above problems, and provides a kind of high precision movement slide unit gear back clearance elimination machine
Structure, the mechanism adapt to domestic processing status avoid simultaneously spring floating anti-backlash mechanism the gap effect that disappears it is unstable and impact
Slippage phenomenon in the case of power.
In order to solve the above technical problems, the technical solution of the utility model is: a kind of high precision movement slide unit gear back clearance
Eliminating machine, including installs rebound, guide pad, latch, fastener one and fastener two are equipped with electricity in installs rebound
Machine speed reducer component and gear, gear are located at the lower section of installs rebound, and the guide pad is posted by installs rebound two sides, makes
Installs rebound can be moved along guide pad, and the left and right ends that the fastener one passes through latch withstand on installs rebound two respectively
On the guide pad end face of side, after adjustment gear position is suitable, installs rebound is fixedly connected with latch by fastener two.
Preferably, the fastener one is screw and nut.
Preferably, the fastener two is screw.
The beneficial effects of the utility model are: high precision movement slide unit gear back clearance provided by the utility model eliminates machine
Structure directly can be realized when installation with fastener (screw) locking installs rebound and eliminate rack pinion back clearance.The mechanism
Install it is easy to operate, can effectively avoid spring floating mechanism disappear gap when need the process of adjustment spring pretightning force, be more convenient worker
Installation.Since the anti-backlash mechanism is disappeared by rigid structure realization between each component gap, the gap that disappears long action time and the gap reliability that disappears
Height is not in slippage phenomenon in use process, can effectively reduce the failure rate in equipment use process, extends maintenance period,
Reduce maintenance cost.

Specific embodiment
The utility model is described further in the following with reference to the drawings and specific embodiments:
As shown in Figs 1-4, the high precision movement slide unit gear back clearance eliminating machine of the utility model, including installs rebound
1, guide pad 2, latch 3, fastener 1 and fastener 25.In the present embodiment, fastener 1 is screw and nut.
Fastener 25 is screw.
As seen in figs. 5-6, when using mechanism, motor reducer component 6 and gear 7 are mounted on installation transition first
On plate 1, motor reducer component 6 is located at 1 top of installs rebound, and gear 7 is located at the lower section of installs rebound 1, gear 7 and electricity
Machine speed reducer component 6 is connected.Installs rebound is fixed on slide plate 9 using screw.It should be noted that motor reducer portion
The connection of part 6 and gear 7 is the conventional connection type of this field, specifically uses the motor reducer component 6 and tooth of which kind of model
The specific connection type of wheel 7 and motor reducer component 6 and gear 7 this substantive influence is had no to the utility model.
Guide pad 2 is posted by 1 two sides of installs rebound again, and is fixedly connected with guide pad 2 with slide plate 9 using screw.
The attachment screw between installs rebound 1 and slide plate 9 is unclamped again, the direction for being oriented to installs rebound 1 along guide pad 1 is moved
Back clearance is eliminated to prepare to adjust.The quantity of fastener 1 (lock-screw) is 3, will by fastener 1 (lock-screw)
Latch 3 is connected in installs rebound 1.25 quantity of fastener is two, and the both ends for being each passed through latch 3 withstand on guiding
The end face of block 2 guarantees that there are certain intervals between latch segment 3 and installs rebound 1.When needing to lock elimination back clearance, then use
Fastener 1 furthers installs rebound 1 and latch 3 can play the role of eliminating between gear 7 and rack gear 8 backwards to gap.
It can guarantee that mechanism is run for a long time without loosening once operator locks all screws i.e..The quantity of fastener 1 and fastener 25
It has no specifically limited, can be set according to actual needs.
Generally speaking, high precision movement slide unit gear back clearance eliminating machine provided by the utility model, when installation, are directly used
Fastener (screw) locking installs rebound, which can be realized, eliminates rack pinion back clearance.Mechanism installation is easy to operate, can
Effectively avoid spring floating mechanism disappear gap when need the process of adjustment spring pretightning force, be more convenient worker's installation.Due to the gap that disappears
Mechanism is that disappear gap, the gap that disappears long action time and the gap high reliablity that disappears are realized by rigid structure between each component, in use process not
It will appear slippage phenomenon, the failure rate in equipment use process can be effectively reduced, extend maintenance period, reduce maintenance cost.
Those of ordinary skill in the art will understand that the embodiments described herein, which is to help reader, understands this reality
With novel principle, it should be understood that the scope of the present invention is not limited to such specific embodiments and embodiments.
Those skilled in the art can be made according to the technical disclosures disclosed by the utility model it is various do not depart from it is practical
Novel substantive various other specific variations and combinations, these variations and combinations are still within the protection scope of the present invention.
