The main frame comprises a multidimensional rotating assembly formed by a plurality of rotating arms which rotate relatively, and the bulb tube and the detector are arranged on the multidimensional rotating assembly so as to adjust the detection posture and angle along with the multidimensional rotating assembly.
In order to adjust the zero position precision of the multidimensional rotating assembly, one of the adjusting steps is to detach the collimator arranged on the bulb, then place the high-precision level on the upper mounting surface of the bulb, then rotate the bulb to keep the level horizontal, and set the installation position of the bulb to zero. In addition, in another adjusting step, a laser leveling instrument with a vertical plane leveling function is required to be placed on the bed board, the C-shaped cantilever provided with the bulb tube and the detector in the multidimensional rotating assembly is rotated by 90 degrees, so that the C-shaped cantilever is in a horizontal state, and then the position of the laser leveling instrument on the bed board is adjusted to form a laser beam plane.

As shown in fig. 1, the scanning device is applied to DSA equipment such as a blood vessel machine, and is used for quickly and accurately adjusting the bulb 42 and the detector to a detection position so as to perform a three-dimensional scanning function. The scanning device comprises a bracket assembly 10, a multi-dimensional adjusting assembly 20 rotatably connected to the bracket assembly 10, and a first detecting assembly 30 and a second detecting assembly 40 which are installed on the multi-dimensional adjusting assembly 20. The multidimensional adjusting assembly 20 comprises a first support arm 21, a second support arm 22, a support arm support 23 and an arc support arm 24 slidably arranged on the support arm support 23, wherein the first support arm 21 is pivotally connected with the bracket assembly 10 through a first rotating shaft 211, the first support arm 21 is pivotally connected with the second support arm 22 through a second rotating shaft 212, and the support arm support 23 is pivotally connected with the second support arm 22 through a third rotating shaft 221. Wherein the axis of the first rotating shaft 211 is parallel to the axis of the second rotating shaft 212, and the axis of the second rotating shaft 212 is perpendicular to the axis of the third rotating shaft 221.
The arc-shaped support arm 24 slides along the support arm frame 23 and rotates around a fourth rotation axis, and the first detection component 30 and the second detection component 40 are respectively installed at two ends of the arc-shaped support arm 24. The radial outer peripheral wall of the arc-shaped support arm 24 is provided with a correction portion 241, and the first support arm 21 is provided with a calibration frame, and the calibration center line of the calibration frame coincides with the axis of the first rotation shaft 211.
When the support arm support 23 is at the zero position, the first arm 21 and the arc arm 24 rotate relative to the bracket assembly 10 until the calibration center line of the calibration frame coincides with the center line of the calibration part 241, and the second rotation shaft 212 and the fourth rotation axis are set to zero.
The first support arm 21, the second support arm 22, the support arm support 23 and the arc-shaped support arm 24 are all made of rigid materials and are made of rigid structural members with stable shapes. The carriage assembly 10 is mounted to a stationary base object to maintain the position of the scanning device stable. For example, the bracket assembly 10 is mounted to the roof of a building, at the upper beam of a suspension, etc. The first arm 21 is rotatably connected to the bracket assembly 10 through a first rotation shaft 211, and can rotate around the axis of the first rotation shaft 211 relative to the bracket assembly 10, and the second arm 22, the support arm support 23 and the arc-shaped arm 24 connected to the first arm 21 all rotate around the bracket assembly 10. That is, the first arm 21 is rotated about the first rotation shaft 211 by the first power member. During the zeroing of the scanning device, the first rotation shaft 211 needs to be zeroed.
The second arm 22 is pivotally connected to the first arm 21 through the second shaft 212, so that the second arm 22 can rotate around the second shaft 212 relative to the first arm 21, and the support arm 23 and the arc arm 24 connected to the second arm 22 both rotate around the first arm 21. That is, the second arm 22 is rotated about the axis of the second shaft 212 by the second power member. During the zeroing process of the scanning device, the second rotating shaft 212 needs to be adjusted to be zeroed. The first rotating shaft 211 and the second rotating shaft 212 are arranged in parallel, so that the supporting arm support 23 and the arc-shaped arm support 24 form a swing arm structure, and the swing range is enlarged.
As shown in fig. 2, the support arm 23 is pivotally connected to the second arm 22 through a third rotation shaft 221, so that the support arm 23 can rotate around the third rotation shaft 221 relative to the second arm 22, and then the arc-shaped arms 24 connected to the support arm 23 rotate around the second arm 22. That is, the support arm 23 rotates around the third rotation shaft 221 under the drive of the third power member, and the third rotation shaft 221 needs to be adjusted to zero during the zeroing process of the scanning device. The second rotation shaft 212 and the third rotation shaft 221 are located at two ends of the second support arm 22, and the second rotation shaft 212 and the third rotation shaft 221 are perpendicular to each other, and the arc-shaped support arm 24 can swing and rotate relative to the first support arm 21. The first detecting assembly 30 and the second detecting assembly 40 mounted at both ends of the arc-shaped support arm 24 move to different detecting angles along with the arc-shaped support arm 24.
The arc-shaped support arm 24 is slidably arranged on the support arm support 23, wherein the support arm support 23 is provided with an arc-shaped chute and a fourth power piece arranged on the chute. The fourth power member drives the arc-shaped support arm 24 slidably disposed in the chute to move, so that the arc-shaped support arm 24 rotates around a fourth rotation axis corresponding to the chute, and the first detection assembly 30 and the second detection assembly 40 are transmitted to different detection angles.
As shown in fig. 3 and 4, the correction portion 241 is provided on the radially outer peripheral wall of the arc-shaped arm 24 as a reference portion for zero setting correction, so that the correction portion 241 can move relative to the calibration frame during rotation of the arc-shaped arm 24. Wherein the alignment jig is located on the first arm 21 with its relative position fixed. The correcting portion 241 moves along with the rotation of the first support arm 21 and the movement of the arc-shaped support arm 24, so that the center line of the correcting portion 241 gradually approaches the correcting portion along with the alternating movement or the synchronous movement of the first support arm 21 and the arc-shaped support arm 24 until the correcting center line of the correcting frame coincides with the center line of the correcting portion 241, and then the second rotating shaft 212 and the fourth rotating shaft are simultaneously set to zero.
The third rotating shaft 221 is in a zero state, and the first support arm 21 and the arc support arm 24 are gradually fine-tuned to make the correction portion 241 approach toward the alignment center line of the alignment frame until the alignment center line of the alignment frame coincides with the center line of the correction portion 241, so that the second rotating shaft 212 and the fourth rotating shaft are simultaneously zero, and the adjustment efficiency is high. The first support arm 21 and the arc support arm 24 are alternately rotated and adjusted so that the second rotating shaft 212 and the fourth rotating shaft are simultaneously set to zero, the requirements on operation skills are low, and the accuracy of the adjusting position is determined by line-to-line alignment, so that the observation is convenient.
The arc-shaped support arm 24 has an arc structure, and the fourth rotation axis of the arc-shaped support arm is basically coincident with the central line of the sliding groove of the support arm frame 23. That is, the sliding track of the arc-shaped arm 24 along the supporting arm frame 23 is an arc formed by the sliding groove. The correction part 241 is synchronously processed in the processing process of the outline dimension of the arc-shaped support arm 24, and the processing position of the correction part 241 on the arc-shaped support arm 24 is accurate. The correction portion 241 is integrally formed with the arc-shaped arm 24, and the accuracy of the machining position of the correction portion 241 is high.
Alternatively, the center line of the correcting portion 241 is perpendicular to the axis of the third rotating shaft 221, and the center line of the correcting portion 241 is located in the radial direction of the arc-shaped arm 24 and intersects with the axis of the fourth rotation axis. When the axis of the third rotation shaft 221 is in a horizontal state and the alignment center line of the alignment frame coincides with the center line of the alignment portion 241, the center line of the alignment portion 241 is in a vertical state perpendicular to the horizontal plane.
The correction portion 241 is directly processed on the arc-shaped support arm 24, for example, the correction portion 241 is configured as a linear rib, a linear groove or a hole-shaped groove structure configured on the arc-shaped support arm 24, so that the correction portion 241 and the arc-shaped support arm 24 are integrally processed and formed, and the position accuracy of the correction portion 241 is improved. When the correction portion 241 is in a linear groove or rib structure, the correction portion 241 and the correction portion are aligned by line-to-line or surface-to-surface alignment, so that the observation convenience is good. In one embodiment, the calibration portion 241 includes a hole-shaped recess disposed on the arc-shaped arm 24. In this embodiment, the hole-shaped groove is configured as a circular counterbore structure, wherein the center line of the correction portion 241 is the axis of the counterbore. For example, the calibration portion 241 may be configured as a blind hole or a through hole with a hole diameter of 2-5 mm, for example, the calibration portion 241 is configured as a through hole with a hole diameter of 2mm, 3mm, 4mm, or 5mm, and the laser beam passes through the calibration portion 241, so that it can be determined that the calibration center line of the calibration frame coincides with the center line of the calibration portion 241, so that the second rotation axis 212 and the fourth rotation axis are set to zero at the same time. Optionally, the radial outer peripheral wall of the arc-shaped support arm 24 is provided with a positioning groove 242, and the correction portion 241 is located in the positioning groove 242, so as to improve the identifiability of the correction portion 241. Optionally, a photosensitive element 243 is disposed at the bottom of the hole of the calibration portion 241 for sensing the light outputted from the calibration portion. When the photosensitive element 243 senses the light stably irradiated, it may be determined that the calibration center line of the calibration frame coincides with the center line of the calibration part 241, so that the second rotation axis 212 and the fourth rotation axis are simultaneously set to zero.
In another embodiment, the calibration portion 241 includes a calibration member fixedly coupled to the arcuate arm 24, the calibration member having a calibration centerline.

Optionally, the correcting element is a columnar structural element and is connected with the arc-shaped support arm 24 in an inserting interference fit manner, and the central part of the correcting element is provided with a photosensitive element 243 for sensing the light output by the correcting element. Alternatively, the calibration member is configured as a columnar protrusion, the end tip of which is directed toward the calibration part, so that the calibration center line of the calibration stand can coincide with the center line of the calibration part 241, so that the second rotation shaft 212 and the fourth rotation axis are simultaneously set to zero.
In one embodiment, as shown in fig. 5, the calibration frame includes a flange mounting opening 213 disposed on the first support arm 21, and the flange mounting opening 213 is used for mounting the calibration device 60 that outputs the calibration light 61, and the calibration light 61 coincides with the calibration center line.

The flange mounting opening 213 is configured as a taper hole or a step hole structure and is used for positioning the mounting precision of the calibration device 60, so that the center line of the calibration device 60 coincides with the calibration center line of the calibration frame, wherein the standard light of the calibration device 60 has the characteristics of small line diameter change, convenient observation and the like. Alternatively, the alignment device 60 is configured as a device capable of outputting a standard light such as a laser beam, in which the shape and the line diameter of the laser beam are small in variation and the user is facilitated to observe, so as to facilitate adjustment of the coincidence of the laser beam and the center line of the correction portion 241.
The support arm 23 is pivotally connected to the second arm 22 via a third rotation axis 221, and the support arm 23 rotates around the third rotation axis 221 relative to the second arm 22. Optionally, the third rotation axis 221 is parallel to the horizontal plane. In an embodiment, the support arm 23 is configured with a first adjusting plane 231 parallel to the third rotating shaft 221, where the first adjusting plane 231 is used for placing the level 50 and the third rotating shaft 221 is set to zero when the air bubble of the level 50 is centered.
In this embodiment, the multidimensional adjustment assembly 20 is mounted on the bracket assembly 10, and the first adjustment plane 231 is disposed on the surface of the support arm 23 and is perpendicular to the horizontal plane or parallel to the horizontal plane when the support arm 23 is in the zeroing state. The first adjusting plane 231 is machined when the supporting arm frame 23 is machined, and the parallelism between the first adjusting plane 231 and the third rotating shaft 221 is high. The level 50 having a high accuracy measurement standard is placed on the first adjustment plane 231, and the offset angle of the bubble of the level 50 can be adjusted by rotating the support arm 23. When the bubble of the level 50 is centered, then the support arm 23 is in the zeroed position, i.e., the third axis of rotation 221 of the multi-dimensional adjustment assembly 20 is zeroed.
After the second arm 22, the support arm 23 and the arc arm 24 are zeroed, the zeroing position of the first arm 21 relative to the bracket assembly 10 needs to be further adjusted.
