Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the invention easy to understand, the invention is further described with the specific embodiments.
Referring to fig. 1, the X-ray diffractometer suspension wire optical well support can be divided into five components.
The upper bearing fine-tuning holder of the magnetic base can be locked and fixed by screws, and the lower bearing fine-tuning holder is connected with the detector protective cover 5 and fixed by magnetic attraction. The base is provided with a knob switch which can control the magnetic force.
The three-axis translational fine tuning holder is divided into an upper section and a lower section, wherein the lower section is an X-axis and Y-axis orthogonal horizontal displacement table, and the upper section is a Z-axis vertical displacement table. The holder can provide displacement distances of about 10mm in three orthogonal directions, and the displacement precision can reach micron level by adopting a micrometer for propulsion.
The sliding rail suspension 4 can provide a horizontal travel of about 100mm for the upper slider 8. The center of the slide block 8 is provided with a horizontal rotating mechanism (without limitation of rotating angle) with angle scales, and the horizontal rotating mechanism is used for connecting the upper end suspension wires 6 of the light well.
The upper end of the suspension wire 6 is connected with the rotating mechanism so as to control the horizontal orientation of the wellhead of the light well. The lower end of the suspension wire 6 is connected with a gravity weight 7. The weight 7 provides a pull-down force to easily stabilize the light well.
A suspension wire 6 between a light well and a weight 7 penetrates through a slit (the width of the slit is 2 mm) on the limiter, so that the light well can rapidly reach a static stable state in the installation and debugging process. The limiter slit is provided with scales for marking the shielding angles of the light-emitting well to the straight rays at different positions.
The component usage workflow is as follows:
step 1: and assembling and integrating the components. As shown in fig. 1, the lockable magnetic base, the three-axis translational fine-tuning pan-tilt and the slide rail cantilever 4 with the slide rail of the device are assembled by fastening screws to form a complete bracket assembly.
Step 2: and mounting the bracket assembly. It is confirmed that the lockable magnetic base switch in the carriage assembly is in the "off" position, in which the base is in a low magnetic state for movement. The component is placed on a top plate of a protective cover 5 of the device detector, the position of the component is moved and adjusted, and the Y axis of a three-axis holder of the component falls in the vertical plane where the direct X-ray of the device is located. After the adjustment is finished, the lockable magnetic base switch is turned to an on position, and at the moment, the base generates strong magnetic force and is attracted to a top plate of the detector protection cover 5.
And step 3: installing a suspension wire light well: and (3) penetrating the lead light well which is assembled in advance through a hole in the middle of a sliding block 8 on a sliding rail cantilever 4 with a sliding rail, and then inserting a knob at the top end of a suspension wire 6 into a rotating hole of the sliding block 8.
And 4, step 4: coarse adjustment: and moving the sliding block 8 on the sliding rail cantilever 4 with the sliding rail, placing the optical well in a fine adjustment stroke range near the target position, and locking and fixing the sliding block 8. And installing a limiter to enable the lower end of the suspension wire 6 to penetrate through the narrow slit of the limiter.
And 5: fine adjustment: three translation shafts on the synchronous adjustment holder and a rotating button at the top end of the suspension wire 6 are matched with the adjustment limiter, so that the suspension wire 6 can pass through the narrow slit of the limiter and can not be contacted with the narrow slit arm when the light well is static. The location of the optical well is detected with low power direct X-rays. Repeating the fine adjustment process until the optical well falls into the required position. Locking pan head X, Y, Z triaxial fixed buttons.
The device performs an optical path calibration operation, sometimes requiring removal of the optical well. And (4) slightly moving the bottom end of the suspension wire 6 of the optical well out of the slit opening of the limiter, and moving the optical well out of the optical path. Note that touching the slit so that the stopper is displaced should be avoided, and pulling the polished rod string so that the string 6 is deformed or the bracket is displaced. If the operation is proper in the step, the bottom end of the suspension wire of the optical well only needs to be slightly moved into the narrow slit of the limiting stopper when the optical well is reset, and the limiting stopper can be deviated without touching the arm of the narrow slit. And if the light path verification finds that the position of the light well is not accurate, repeating the fine adjustment operation process of the step 5. After the fine adjustment is completed, the optical well is shifted to the light shielding position again from the light path deviation position.
