Abstract
The invention discloses a manual mechanism for accurately adjusting an angle. The manual mechanism is characterized by comprising a handle, a rotary screw, a moving nut, a rack, a gear, a base plate, a supporting plate and a part fixing and guiding device, wherein the base plate is hinged with the supporting plate together through a rotating shaft; the rotating shaft is fixedly arranged on the supporting plate; the part fixing and guiding device is arranged on the supporting plate; the handle is fixedly arranged on the rotary screw; the moving nut is in threaded connection with the rotary screw and is fixedly connected with the rack; and the gear is meshed with the rack and is coaxially and fixedly arranged on the rotating shaft. According to the manual mechanism disclosed by the invention, the angle can be accurately controlled and the self-locking function of threads can achieve the effects for firmly and reliably locking the work position of the supporting plate. With the guiding action of a dovetail groove, the motion of the whole mechanism is avoided, the accuracy and reliability in motion are realized and the processing precision is improved.
Description
Technical field
The present invention relates to a kind of accurate governor motion of manual angle.
Background technology
Present a kind of part chamfer mechanism has a kind of angle adjusting mechanism to be used for fixing part in this mechanism, and makes part be adjusted to certain machining angle.But there is the deficiency of following several respects in this angle: one, and angle control is inaccurate, and the angle of swinging two plates with hand is leaned in the adjusting of angle fully, and factors such as the vibration of hand all influence the accuracy of angle.Two, it is not firm to lock, and only depends on the frictional force of tightening the locking nut generation to pin the relative position between two plates, locks insecure.Three, whole angle adjusting mechanism is all in motion, and the no guider of motion, the precision of influence processing.
Summary of the invention
The present invention seeks to propose a kind ofly can accurately control pendulum angle, utilize the auto-lock function of screw thread to reach the effect of solid and reliable locking, and have dovetail groove and lead, guarantee the precise angle governor motion of machining accuracy.
The present invention adopts following technical scheme for realizing above-mentioned purpose:
The accurate governor motion of a kind of manual angle is characterized in that: comprise handle, rotary screw, travelling nut, tooth bar, gear, base plate, support plate and part fixed guide; Said base plate and support plate are hinged through rotating shaft, and said rotating shaft is fixed on the said support plate; Said part fixed guide is arranged on the said support plate; Said handle is fixed on the said rotary screw, and said travelling nut is threaded with said rotary screw, and said travelling nut is fixedly connected with tooth bar, and said gear is meshed with said tooth bar, and said gear is coaxial to be fixed in the said rotating shaft.
It is further characterized in that: said part fixed guide comprises slide block, positioning screw, locking nut and horizontal follower lever; Said slide block cooperates with said support plate through dovetail groove; Said slide block can slide on said support plate; Said positioning screw is a double threaded screw; One is inserted said slide block and forms threaded engagement, other one and said locking nut formation threaded engagement, and said horizontal follower lever and said slide block are fixed together.
Angle of the present invention can arrive accurately control, and the auto-lock function of screw thread reaches the effect of the operating position of firmly, reliably locking support plate.The motion of entire mechanism has been avoided in the guide effect of dovetail groove, makes motion accurately and reliably, improves machining accuracy.

The specific embodiment
The accurate governor motion of a kind of manual angle as shown in Figure 1 comprises handle 10, rotary screw 8, travelling nut 9, tooth bar 7, gear 6, base plate 11, support plate 13 and part fixed guide; Said base plate 11 is hinged through rotating shaft 12 with support plate 13, and said rotating shaft 12 is fixed on the said support plate 13; Said part fixed guide is arranged on the said support plate; Said handle 10 is fixed on the said rotary screw 8, and said travelling nut 9 is threaded with said rotary screw 8, and said travelling nut 9 is fixedly connected with tooth bar 6, and said gear 6 is meshed with said tooth bar 7, said gear 6 coaxial being fixed in the said rotating shaft 12.Said part fixed guide comprises slide block 1, positioning screw 4, locking nut 5 and horizontal follower lever 3; Said slide block 1 cooperates with said support plate 13 through dovetail groove 14; Said slide block 1 can slide on said support plate 13; Said positioning screw 4 is a double threaded screw; One is inserted said slide block 1 and forms threaded engagement, other one and said locking nut 5 formation threaded engagement, and said horizontal follower lever 3 is fixed together with said slide block 1.
Hand rotation handle 10 during use produces rotary screw 8 and rotatablely moves.Rotatablely moving of rotary screw 8 is converted into the rectilinear motion of travelling nut 9.Travelling nut 9 is fixed by welding in tooth bar 7, makes tooth bar 7 moving linearlies.Tooth bar 7 is meshed with gear 6, and the rectilinear motion of tooth bar 7 converts the swing of gear 6 into.Gear 6 is that key is connected with connected mode between the rotating shaft 12.Thereby the swing of gear 6 converts the swing of rotating shaft 12 into.The swing of rotating shaft 12 converts the swing of support plate 13 into.Slide block 1 cooperates with support plate 13 through dovetail groove 14, and slide block 1 can slide on support plate 13, and dovetail groove 14 has played and led and the fixing function of slide block 1.Positioning screw 4 inserts in the positioning process hole of part 2, and fixes through locking nut 5, and the part 2 of weaving so just is fixed on the slide block 1.Laterally follower lever 3 is fixed by welding in slide block 1, and laterally follower lever 3 promotes slide block 1 and on support plate 13, does laterally slip along dovetail groove 14, promptly promotes part 2 and does laterally to slide.Because the screw thread transmission has the performance of self-locking, so can arrive the operating angle of firm pinning support plate 13.
