[0023] See also Figures 1 to 4 The utility model provides a casing warpage detection device. The casing warpage detection device can be used to detect the warpage of quartz casings, and can also be used to detect the warpage of other pipes. The operation method and detection principle are exactly the same as those of detecting quartz casings.

[0024] The casing warpage detection device includes a fixing device 1, a displacement device 2 and a detection device 3.

The detection device 3 includes a plurality of detectors 31 arranged around the casing 4, and the detector 31 can detect the distance between the detector 31 and the casing 4.

[0025] When the sleeve 4 is straight, the distances between each detector 31 and the sleeve 4 should be equal.

The greater the difference in distance detected by each detector 31, the greater the warping degree of the sleeve 4. By driving the detector 31 to move along the axial direction of the sleeve 4 by the displacement device 2, the overall warping degree of the sleeve 4 can be obtained, which greatly improves the efficiency of the staff in detecting the warping degree of the quartz tube.

[0026] In some embodiments, the fixing device 1 further comprises a first telescopic mechanism 13, which is transmission-connected with the movable head 12 to drive the movable head 12 to move along the axial direction of the sleeve 4, thereby loosening and tightening the sleeve 4.

[0033] In some embodiments, the detection device 3 further includes a plurality of second telescopic mechanisms 33 , which are disposed on the assembly ring 32 and are transmission-connected to the detectors 31 in a one-to-one correspondence to drive the detectors 31 to move radially along the sleeve 4 to adapt to sleeves 4 of different diameters.

[0034] See also Figure 4In this embodiment, the second telescopic mechanism 33 includes an adjusting box 331, a threaded rod 332, a knob 333 and a movable block 334.
