[specific embodiment]
Below in conjunction with accompanying drawing the present invention is further described.
Embodiment one:
To shown in Figure 4, X-ray equipment of the present invention is taken the photograph sheet lattice motion control device and is comprised casing 1 like Fig. 1, places the magazine coaster 2 in the casing 1, and the actuating device 3 that places casing interior 1.Actuating device comprises the line slideway of being made up of last rail 4 and following rail 5, and last rail 4 is provided with magazine coaster 2, and the last rail 4 corresponding both sides of the junction of rail 5 down are provided with groove 6, is provided with in the groove 6 to be used to prevent that the brake block 7 that magazine coaster 2 runs sheet from contacting with following rail 5; Last rail 4 surfaces also are provided with oilhole 11 and communicate with the sidewall of groove 6.Brake block 7 one sides are that arcuation bulge-structure 8 contacts with the sidewall of groove 6, and the arcuation bulge-structure contacts for point with the sidewall of groove, and the contact of phase specific surface can better be played a supporting role; Because of the face contact maybe be after long-time the use; Because of the relation of frictional force, the surface may produce wearing and tearing, causes surface irregularity; The sidewall of groove can't carry out reliable supporting to back-up block, adopts the arcuation bulge-structure to avoid the generation of this situation.There is the space that is used to fill hydraulic oil in the sidewall of the both sides of arcuation bulge-structure 8 and groove 6.Brake block 7 is provided with metal hard-sealing 9 with the contact position of following rail 5, and brake block 7 is provided with metal sealing 10 with the rubbing surface of groove 6.
As shown in Figure 5, during work, hydraulic oil 12 is sent through oil pump in the groove 6 of as above rail 4, brake block 7 is under the pressure effect of hydraulic oil 12, and the both sides of rail 5 apply active force downwards, thereby realize arresting purpose.
As shown in Figure 6; When taking the photograph the work of sheet lattice motion control circuit, signal generator sends signal to driver element, and last rail edge rail down moves forward; When arriving preset position; Signal generator sends signal to driver element, and driver element decommissions, and the synchronous signal generator sends signal to MCU Microprocessor Control Unit; The little processing and control element (PCE) control oil pump groove injection hydraulic oil in the rail that makes progress, brake block applies active force in the downward rail of the pressure effect both sides of hydraulic oil and reaches arresting purpose; When the magazine coaster need be retreated; Signal generator sends signal to little processing and control element (PCE), and the hydraulic oil that little processing and control element (PCE) control oil pump will be gone up in the rail groove absorbs, and brake block loosens; The synchronous signal generator sends signal to driver element, and original position is got back on last rail edge rail down.
Embodiment two:
A kind of distortion as above-mentioned embodiment; As shown in Figure 4, also be provided with magnetic coil 14 in the following rail 5, and brake block adopts strong magnets 13 with the end that contacts of following rail 5; Generating through magnetic coil tightly is adsorbed on down brake block 7 on the rail 5, thereby realizes arresting purpose.
