Abstract
The utility model relates to an intermittent film-feeding mechanism of a high-speed camera, which is composed of a crank rocker type film fixing mechanism and a double crank film clawing mechanism with a compensation mechanism. The utility model is characterized in that a film fixing pin in the film fixing mechanism is arranged above imaging pictures; a film claw in the film claw mechanism is arranged above the film fixing pin; eccentric shafts on a driving gear and each of driven gears drive the film fixing pin and the film claw to intermittently cooperate and move. The utility model reduces the requirements of fabrication process, improves the acting force of the film fixing pin to a film perforation, enhances imaging quality, and can avoid damaging to the film perforation and the resulting film shake.
Description
The utility model belongs to the improvement of the intermittent film transport apparatus structure of intermittent high-speed camera.
In intermittent high-speed camera, realize high speed, high-quality film trasport and imaging, should make intermittent film transport mechanism itself have good high-speed motion characteristic, could control and carry film reliably.Though intermittent film transport mechanism of the prior art has adopted the double crank type in-and-out movement, be that offset has higher accuracy requirement to the centre distance and the crank length of double-crank.Usually, the form of intermittent film transport mechanism takes the stator pin last, and claw is following.Because the foozle of film and the influence that shunk by temperature, stator pin be the film perforation on the easy damage film in the process of control film, so that causes that film has bigger shake, influences image quality.
The purpose of this utility model is at problems of the prior art, a kind of high-speed camera intermittent film transport mechanism is provided, it can reduce the technological requirement of mechanism's making and can control and carry film effectively, prevent the damage of film film perforation and the film judder that causes, image quality is improved.
For reaching above-mentioned goal of the invention, the intermittent film transport mechanism of technical solutions of the utility model is made up of double-crank in-and-out movement with compensation mechanism and crank-rocker style stator mechanism.Its design feature is, the stator pin in the described stator mechanism places the top of imaging place, is through in the forward and backward guide rail.The contiguous block that the middle part of stator pin is provided with the perpendicular bar hole of band is connected with the excentric shaft of set driven wheel.The both sides, top of driven wheel are parallel to be engaged with two follower gears, is equipped with excentric shaft on each follower gear, is positioned on the excentric shaft of rear end follower gear concentric bearings is housed, and on the excentric shaft of front end follower gear capacity eccentric bearing is housed.Hold in concentric bearings and sheet axle claw is installed.Minimum spacing between stator pin and the claw is a perforation pitch.
According to technique scheme, the offset of described capacity eccentric bearing inner and outer ring is 0.02～0.05mm, the angle of the crossing of stator pin and claw is controlled between 5 °～15 ° is advisable.
Because the utility model has adopted claw to place the top of stator pin, stator pin to place top, imaging picture place, and make minimum spacing between claw and the stator pin be controlled at a perforation pitch of film.Compared with prior art, not only can reduce the technological requirement of making but also improve the acting force of stator at the film film perforation, can avoid damaging the film film perforation, the shake of film obviously improves image quality when having reduced exposure.
Below in conjunction with accompanying drawing and concrete embodiment the utility model is further described.
Accompanying drawing is a structural representation of the present utility model.
Referring to accompanying drawing, the designed high-speed camera intermittent film transport mechanism of the utility model is made up of double-crank in-and-out movement with compensation mechanism and crank-rocker style stator mechanism.Stator pin 5 in the described stator mechanism places the top of image space, is through in the forward and backward guide rail 6.The contiguous block that the middle part of stator pin 5 is provided with the perpendicular bar hole of band is connected with the excentric shaft of set driven wheel 1, and parallel follower gear 2 and 3 of being engaged with, the both sides, top of driven wheel 1 are equipped with excentric shaft on the follower gear 2 and 3.Concentric bearings 7 is housed on the excentric shaft of follower gear 2, capacity eccentric bearing 8 is housed on the excentric shaft of follower gear 3.Claw 4 is installed on concentric bearings 7 and capacity eccentric bearing 8.Minimum spacing between stator pin 5 and the claw 4 is a perforation pitch.The offset of above-mentioned capacity eccentric bearing 8 inner and outer rings is 0.02～0.05mm, and the angle of the crossing of stator pin and claw is controlled between 5 °～15 °.
When driven wheel 1 rotated, follower gear 2 and 3 also rotated simultaneously in the use.Stator pin 5 is being done straight reciprocating motion under the drive of the excentric shaft of driven wheel 1 in forward and backward guide rail 6.Do plane motion under the drive of claw 4 by concentric bearings 7 and capacity eccentric bearing 8.When claw 4 had just entered film film perforation 9, stator pin 5 was still controlled film, broke away from film subsequently.Claw 4 drives film and moves a picture distance, and before claw 4 withdrawed from film film perforation 9, stator pin 5 was controlled film again, and film is maintained static.
