Referring to fig. 1 and 2, the present embodiment provides an apparatus for straightening a quartz tube rod, which includes a support platform 100 and a straightening body 200. The support platform 100 is located below the quartz tube rod to be straightened. The straightening body 200 is provided with a supporting plane 220 and a flattened end face 210, the straightening body 200 is located between the supporting platform 100 and the quartz tube rod, the supporting plane 220 is attached to the table top of the supporting platform 100, and the flattened end face 210 is in contact with the part to be straightened of the quartz tube rod and used for flattening a bending point.
The device for straightening the quartz tube rod is matched with a deposition lathe and a melting and shrinking lathe to be used together, when the device is straightened, two ends of the quartz tube rod are clamped on the rotating clamp head of the deposition lathe or the melting and shrinking lathe to rotate at a certain rotating speed, and meanwhile, the part to be straightened of the quartz tube rod is melted and softened by adopting the flame blowtorch. Placing alignment main body 200 through setting up supporting platform 100, supporting platform 100 is put in the below of quartz capsule stick, can provide the support for alignment main body 200, makes alignment main body 200 be in suitable high position. Alignment body 200 has a support flat 220 and a flattened end face 210. The support plane 220 and the top of the support platform 100 are engaged, so that the alignment body 200 can move on the support platform 100 smoothly and gradually close to the position of the quartz tube rod to be aligned. The department of alignment is treated to the mill flat of mill flat terminal surface 210 that utilizes alignment main part 200, because the quartz capsule stick rotates around its axis with certain rotational speed on rotatory chuck, and treat that the quartz capsule stick surface of alignment department has certain crookedness, so when alignment main part 200 with treat the contact of alignment department, the contact between quartz capsule stick surface crookedness point and the alignment main part 200 makes alignment main part 200 receive unstable effort, thereby cause the violent rocking of alignment main part 200, after treating the alignment department and being milled flat, the rocking of alignment main part 200 disappears. In the alignment process of using the device to carry out the quartz capsule stick, keep alignment main part 200 and treat that the alignment department contacts throughout, operating personnel can obviously feel the motion change of alignment main part 200 to judge whether the alignment department of treating of quartz capsule stick is straightened in view of the above.

Of course, in other embodiments, alignment body 200 may be made of metal or stainless steel.
It will be appreciated that the shape of alignment body 200 and the angle of inclination of flattened end face 210 relative to support plane 220 will affect the location of the contact point between flattened end face 210 and the quartz tube rod. In this embodiment, the supporting plane 220 and the flat end surface 210 are disposed at an acute angle, which facilitates the contact between the flat end surface 210 and the portion of the quartz tube rod to be straightened. Further, the side length of the triangle is 8cm to 12cm, and illustratively, may be 8cm, 10cm, 12cm, or the like. The thickness of the alignment body 200 is 1cm-2cm, and may be, for example, 1cm, 1.5cm, or 2cm, and may be set according to the width of the alignment portion.
The handle 230 is connected to the straightening main body 200, so that an operator can conveniently hold the straightening main body by hand, and meanwhile, when the bending point is in contact with the grinding end face 210, acting force applied to the straightening main body 200 is transmitted to the handle 230, so that the handle 230 can be violently swung, and the operator can judge whether the part to be straightened of the quartz tube rod is straightened. The handle 230 may be a wooden handle 230, and the wooden handle 230 is relatively light and handy, so that an operator can clearly feel the swing of the handle 230 when holding the handle 230.
Further, the handle 230 has a rod shape, and the length thereof is 15cm to 20cm, and may be, for example, 15cm, 17.5cm, 20cm, or the like. The handle 230 should be of a length sufficient to allow the operator to visibly perceive the power being thrown by the handle 230. The handle 230 extends in a direction perpendicular to the axial direction of the quartz tube rod and forms an acute angle with the table top of the support platform 100. Thereby facilitating the operator to hold the handle 230 to adjust the straightening body 200 to the position where it contacts the part to be straightened.

The height of the support platform 100 is set at 30cm-40cm, and may be, for example, 30cm, 35cm, 40cm, or the like. The width of the plate is 5cm to 15cm, and may be, for example, 5cm, 10cm, 15cm, or the like. The thickness of the flat plate is 0.5cm to 1.5cm, and illustratively, may be 0.5cm, 1cm, 1.5cm, or the like. It will be appreciated that the height of support platform 100 may be set according to the size of alignment body 200, and in this embodiment, the distance from the mesa of support platform 100 to the quartz tube rod is approximately equal to half the height of alignment body 200, about 2cm to 5cm, and may be, for example, 2cm, 3.5cm, or 5cm, etc. The size of the flat plate can be set according to actual needs.
Further, the support platform 100 further has a base 110, and the base 110 is connected to the flat plate through a connecting plate disposed vertically. In use, the base 110 is placed on the running table of a deposition lathe or a melt shrink lathe. In this embodiment, the base 110 is formed by connecting a horizontal connecting plate and two vertical connecting plates, and in other embodiments, the base 110 may have other structural forms, and any structural form that can place the supporting platform 100 on a lathe is within the scope of the present application. The base 110 may also be configured to be a slide rail or other structure that facilitates the movement of the supporting platform 100, and may be configured according to the use requirement.
