Description
Technical field
The utility model relates to a kind of angle fine-adjustment mechanism.
Background technique
Turntable angle fine-adjustment mechanism is extensive in machinery, electronic correlation sector application, and practicability is stronger.Traditional turntable angle fine-adjustment mechanism, generally has three kinds of structures: the first utilizes coupling rigidity or elastic transmission by stepping, servo motor shaft and rotation of rotary table axle; The second utilizes gear and gear, turbine and worm drive by stepping, servo motor shaft and rotation of rotary table axle; The third utilizes synchronous pulley and toothed belt transmission by stepping, servo motor shaft and rotation of rotary table axle.
The turntable angle fine-adjustment mechanism of said structure, its turntable limited torque is in the holding torque of motor, so poor stability when turntable is equipped with beater mechanism; And due to gear and gear, there is back lash between turbine and worm screw, make the control inaccuracy of angle; Construction profile is size-constrained can not be effectively reduced in motor volume and gear, turbine box (requiring high pulling torque occasion).
Model utility content
The utility model, in order to solve problems of the prior art, provides a kind of turntable angle fine-adjustment mechanism.
In order to realize above-mentioned object, the technical solution of the utility model is: a kind of turntable angle fine-adjustment mechanism, comprises substrate, also comprises the swing arm be rotatably connected on substrate, described swing arm is provided with a chute angularly distributed with swing arm median vertical line; Also comprise the roller screw being fixed on and substrate being controlled by drive unit, and the nut coordinated with roller screw, described nut is fixed the guide rod that a termination coordinates with chute.
Preferably, the median vertical line of described swing arm passes the center of chute.
Preferably, the top of described substrate is provided with shaft seat, and described swing arm is connected in shaft seat by axis of rotation.
Preferably, described drive unit is the actuating motor be fixed on substrate.
Preferably, described substrate is also provided with guide rail, described guide rod leads with guide rail and coordinates.
Preferably, described spiral arm is provided with tooling platform.
Preferably, described chute is the through hole of through swing arm both sides.
Turntable angle fine-adjustment mechanism of the present utility model, the moment in the Vertical direction provided by roller screw, be converted into the moment that swing arm swings, the pendulum angle scope of swing arm is α+γ degree.The angle of choose reasonable chute and swing arm vertical center line, the pitch of roller screw, can realize the minute angle adjustment of turntable; And utilize the auto-lock function of roller screw, even if adopt little torque motor also can realize the stable operation of turntable under impact conditions frequently.Turntable angle fine-adjustment mechanism of the present utility model, its structure is simple, compact, can flexibly, long reliably working.

Embodiment
The technical problem solved to make the present invention, the technological scheme of employing, the technique effect easy to understand obtained, below in conjunction with concrete accompanying drawing, be described further the specific embodiment of the present invention.
With reference to figure 1, the utility model discloses a kind of turntable angle fine-adjustment mechanism, comprise substrate 1, for whole mechanism provides support, be rotationally connected a swing arm 5 in the upper end of substrate 1.Such as can arrange a shaft seat 2 on the top of substrate 1, described swing arm 5 is rotatably connected in shaft seat 2 by rotating shaft 3, realizes being rotationally connected between swing arm 5 and substrate 1.In its natural state, swing arm 5 is positioned at vertical state.
Described swing arm 5 is provided with chute 10, and with reference to figure 2, this chute 10 is at an angle with swing arm 5 median vertical line, and namely this chute 19 is tilt distribution, and its length direction along swing arm 5 is towards lopsidedness.This chute 10 can be blind slot, also can be the through hole of through swing arm 5 both sides.
Turntable angle fine-adjustment mechanism of the present utility model also comprises fixing roller screw 9 on substrate 1, and the nut 11 to coordinate with roller screw 9, by driving roller screw 9, nut 11 can be moved up and down along roller screw 9, the drive unit of roller screw 9 can be fixing actuating motor 7 on substrate 1, can certainly be other devices well-known to those skilled in the art.
Described nut 11 flatly fixes a guide rod 6, and the chute 10 in the termination of this guide rod 6 and swing arm 5 is combined together.
Turntable angle fine-adjustment mechanism of the present utility model, is moved up and down by roller screw 9 drive nut 11, guide rod 6.When roller screw 9 drive leader 6 moves up time, the chute of the termination extruding swing arm of guide rod 6, makes swing arm rotate towards side, such as, drives swing arm to rotate clockwise; Based on identical reason, when roller screw 9 drive leader 6 moves down time, the chute of the termination extruding swing arm of guide rod 6, makes swing arm rotate towards opposite side, such as, drives swing arm to rotate counterclockwise.Preferably, the median vertical line of described swing arm 5 passes the center of chute 10, with reference to figure 3.Now, when the termination of guide rod 6 is positioned at the center of this chute 10, the deflection angle of swing arm is 0 °.When roller screw 9 drive leader 6 moves to the top of chute 10, with reference to figure 4, now, the deflection angle of swing arm is+α.When roller screw 9 drive leader 6 moves to the bottom of chute 10, with reference to figure 5, the deflection angle of swing arm is-γ.
Turntable angle fine-adjustment mechanism of the present utility model, the moment in the Vertical direction provided by roller screw, be converted into the moment that swing arm swings, the pendulum angle scope of swing arm is α+γ degree.Choose reasonable chute 10 and the angle of swing arm 5 vertical center line, the pitch of roller screw 9, can realize the minute angle adjustment of turntable; And utilize the auto-lock function of roller screw 9, even if adopt little torque motor also can realize the stable operation of turntable under impact conditions frequently.Turntable angle fine-adjustment mechanism of the present utility model, its structure is simple, compact, can flexibly, long reliably working.
Turntable angle fine-adjustment mechanism of the present utility model, in order to ensure that guide rod 6 moves in vertical direction, also arranges a guide rail 8 on substrate 1, and described guide rod 6 leads with guide rail 8 and is combined together.
Turntable angle fine-adjustment mechanism of the present utility model is when work, can measuring tool or other outfit be arranged on spiral arm, realize the adjustment of angle, the utility model preferably, described spiral arm 5 is also provided with tooling platform 4, for installing various required instrument.
The present invention is by preferred embodiment having carried out detailed explanation.But, by studying carefully above, concerning the change of each mode of execution with to increase be apparent for one of ordinary skill in the art.Being intended that these changes all and increasing of claimant has all dropped in scope that the claims in the present invention protect.
