Problems solved by technology
In the prior art, the adjustment of the position of the CT tube is generally realized by pushing and pulling the adjustment screws in the X and Z directions, but this solution has the following disadvantages: 1. When adjusting in the X and Z directions, the position Due to mutual influence, it is difficult to adjust to the required position accurately. Repeated and alternate adjustments in two directions are required, which takes a long time; The mutual influence of two directions cannot achieve fine adjustment; 3. The micro adjustment of the CT tube angle cannot be carried out

Embodiment Construction
[0042] Below in conjunction with embodiment the present invention is described in further detail.
[0043] In the prior art, the CT tube is installed on the CT rotor through the tube bracket, such as figure 1 and 2 As shown, the CT rotor 19 has a mounting hole at the mounting bracket. The CT tube adjustment device of this embodiment is located at the mounting hole of the CT rotor. The CT tube is installed in the tube bracket 1. on the top surface of the pipe support 1. The spatial coordinate system of the ball tube in this application is as figure 2 shown in .
[0044] Such as Figure 3-8 As shown, it includes a guide rail 2 arranged in the Z direction, and the two ends of the guide rail 2 are provided with screw holes 5 10, and the screw holes 5 10 are provided with bracket connecting screws 2 connected with the ball tube bracket 1. The guide rail 2 is provided with a parallelogram slider 3, and the parallelogram slider 3 is provided with a guide groove 15 matched with ...

The invention relates to the field of CT bulb tube manufacturing, in particular to a CT bulb tube accurate adjusting device and adjusting method. The device comprises a bulb tube support for mountinga CT bulb tube and a CT rotor, a guide rail arranged in the Z direction is fixedly connected to the bulb tube support. Parallelogram slide blocks are arranged on the guide rails; bulb tube fixing plates fixedly connected with the bulb tube are tightly attached to the two sides of the parallelogram sliding block in the X direction; connecting plates are arranged on the two sides of the parallelogram sliding block in the Z direction. Two ends of the connecting plate are fixedly connected with the bulb tube fixing plate; a first screw hole and a second screw hole are formed in the connecting plate, Z-direction adjusting screws abutting against the guide rail are arranged in the first screw hole, X-direction adjusting screws abutting against the parallelogram sliding block are arranged in thesecond screw hole, the two Z-direction adjusting screws are located on the same axis, and the two X-direction adjusting screws are in central symmetry. The device has the advantages that the device iscompact in structure and small in size, and independent adjustment of the X direction, the Z direction and the angle can be achieved through the device without mutual influence; high-precision fine adjustment in the X direction can be realized.
Description
technical field [0001] The invention relates to the field of CT tube manufacturing, in particular to a CT tube precise adjustment device and adjustment method. Background technique [0002] When installing and maintaining the CT tube, the position needs to be adjusted to achieve the accuracy of the position and ensure the scanning effect. In the prior art, the adjustment of the position of the CT tube is generally realized by pushing and pulling the adjustment screws in the X and Z directions, but this solution has the following disadvantages: 1. When adjusting in the X and Z directions, the position Due to mutual influence, it is difficult to adjust to the required position accurately. Repeated and alternate adjustments in two directions are required, which takes a long time; The mutual influence of two directions cannot achieve fine adjustment; 3. The micro adjustment of the CT tube angle cannot be performed. Contents of the invention [0003] In order to solve the abo...
