Abstract
The utility model discloses a helical gear transmission unit for an image instrument, which comprises an image instrument-fixing seat; wherein, an image instrument lens-fixing seat is assembled on the upper part of the image instrument-fixing seat; a lens-fixing seat-lifting shaft is fixed on the lower part of the image instrument lens-fixing seat; a helical lifting shaft gear is arranged on the lower end of the lens-fixing seat-lifting shaft; and a lifting nut seat is connected with the screw rod of the lens-fixing seat-lifting shaft by an assembled lifting nut. By rotating a lifting gear handwheel, a slidable block fixed on the lifting nut seat can drive an image instrument lens fixed on an image instrument lens-fixing bracket to move up and down. Since the 45-degree helical gear drives the lifting nut to move relative to the screw rod of the lens-fixing seat-lifting shaft to cause the up-and-down movement of the image instrument lens, i.e., the up-and-down movement along the Z axis, transmission is flexible, the self-locking performance is high, gaps do not exist, and consequently, the image instrument lens can be located at any position to precisely focus, thus ensuring the measurement, positioning and calibration precision of the image instrument in the process of measurement by magnification.
Description
Technical field
The utility model belongs to the fine measuring instrument equipment technical field, relates to a kind of image instrument adjusting gear, is specifically related to a kind of image instrument screw-wheel gearing.
Background technology
Be respectively equipped with the adjusting mechanism of three coordinates at same industry image instrument of the prior art adjusting gear, the lifting of image instrument camera lens is that moving up and down generally of Z axle undertaken by the wheel and rack transmission, this kind of drive shortcoming is that the rack-and-pinion transmission accuracy is poor, there is the gap in the rack-and-pinion transmission, poor stability, Z-direction can't be completely fixed.Therefore the size of image instrument measurement by magnification and the accuracy of calibration accuracy are affected, tend to cause the quality problems of product, thereby influenced the prestige and the economic interests of enterprise.Make enterprise suffer tremendous loss.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, image instrument screw-wheel gearing easy to install, this structure of this device has got rid of that the rack-and-pinion transmission accuracy is poor, there is the gap in the rack-and-pinion transmission, stability is high, because the self-locking performance that spiral gear possesses, the problem that Z-direction can't be completely fixed has obtained solution, the prior art application limit also take on a new look.
The technical scheme that the utility model adopted is, a kind of image instrument screw-wheel gearing, comprise image instrument holder, installation one image instrument lens fixing base is set on image instrument holder top, install and fix a lens fixing base lifting shaft in image instrument lens fixing base bottom, be provided with a lifting shaft spiral gear in the lower end of lens fixing base lifting shaft, screw mandrel position at the lens fixing base lifting shaft connects a lifting nut seat by the lifting screw of installing, fall nut seat and be fixed on the sliding shoe inboard, install and fix image instrument camera lens fixed mount in the outside of sliding shoe, image instrument camera lens is fastened on the image instrument camera lens fixed mount; On the right side, bottom of image instrument lens fixing base one lifter wheel hand wheel shaft is set, lifting spiral gear that install lifter wheel hand wheel shaft end and the engagement of lifting shaft spiral gear drive the lens fixing base lifting shaft and rotate.
The utility model image instrument screw-wheel gearing, its feature also be,
Also be provided with riser guide between described image instrument lens fixing base and the lifting nut seat.
Described lifting shaft spiral gear and lifting spiral gear adopt 45 ° of oblique angles.
The beneficial effect of the utility model image instrument screw-wheel gearing is, because being moving up and down of Z axle, the elevating movement of image instrument camera lens adopt 45 ° of spiral gears to drive screw and the motion mutually of screw mandrel do, transmission effective, the precision of transmission and stability all are greatly improved than the existing rack-and-pinion kind of drive, have solved the problem that moving up and down of Z axle quick and precisely located and Z-direction can't be completely fixed.Make the size of image instrument measurement by magnification and the accuracy of calibration accuracy influenced by other factors.When the quality of product and economic benefit improve greatly, also reduced enterprises' loss, strengthened the prestige of enterprise.
