It will be appreciated that the length of the guide teeth 22 may be determined according to actual design requirements and is not limited in any way herein.
It should be noted that the overall outer diameter of the first sleeve body 21 after being connected to the first threaded portion 13 is not greater than the outer diameter of the second threaded portion 14, so as to avoid the influence on the installation of the stop collar 4.
As shown in fig. 4, the centering sleeve 3 is mainly used for supporting a glass tube, the centering sleeve 3 is composed of a second sleeve body 31 and fixing teeth 32, the second sleeve body 31 is of a barrel-shaped structure and is used for being inserted into the glass tube, a through hole is formed in the center position of the second sleeve body 31 along the axial direction of the through hole, the through hole of the second sleeve body 31 is a conical hole, and the conical degree of the through hole is the same as that of the first connecting column 11.
Because the taper of the central through hole of the second sleeve body 31 is the same as that of the first connecting column 11, the connection of the centering sleeve 3 and the first connecting column 11 is facilitated, the workpiece is prevented from being damaged when the centering sleeve 3 and the first connecting column 11 are sleeved, and meanwhile, the guiding function can be achieved, and the centering of the centering sleeve 3 and the first connecting column 11 is ensured.
The inner diameter of the front end of the second sleeve body 31 (i.e. the end of the second sleeve body 31 far away from the first threaded portion 13) is smaller than the inner diameter of the rear end thereof, which can be understood as that the wall thickness of the front end of the second sleeve body 31 is larger than the wall thickness of the rear end thereof, so as to ensure that the overall outer diameter of the second sleeve body 31 is the same, i.e. any cross-sectional area of the second sleeve body 31 is the same, and the coaxiality of the glass tube and the centering tool after installation is effectively ensured.
The second sleeve 31 is provided with a plurality of elongated slots 33 at intervals along the circumferential direction, the elongated slots 33 extend along the axial direction of the second sleeve 31, the elongated slots 33 penetrate through the second sleeve 31 in the radial direction, one end of each elongated slot 33 penetrates through the end part of the adjacent second sleeve 31, the other end does not penetrate through the end part of the adjacent second sleeve 31, and the end parts of the second sleeves 31 penetrated by the two adjacent elongated slots 33 are different, for example, when one end of one elongated slot 33 penetrates through the front end of the second sleeve 31, one end of the other elongated slot 33 adjacent to the one end penetrates through the rear end of the second sleeve 31, so that the second sleeve 31 can be cut and the integrity of the second sleeve 31 is ensured, and the second sleeve 31 has radial expansion/contraction capability.
The fixed teeth 32 are provided with a plurality of fixed teeth 32, the fixed teeth 32 are fixedly arranged on the outer surface of the second sleeve body 31, and the axis of the fixed teeth 32 is perpendicular to the axis of the second sleeve body 31, namely, the fixed teeth 32 extend outwards along the radial direction of the second sleeve body 31.
The fixed teeth 32 are adjacent to the rear end of the second sleeve 31, a plurality of fixed teeth 32 are arranged at intervals along the circumferential direction of the second sleeve 31, the number of the fixed teeth 32 is the same as that of the guide teeth 22 (also can be understood as the guide grooves 23), and when the centering sleeve is assembled, the fixed teeth 32 are correspondingly inserted into the guide grooves 23 between two adjacent guide teeth 22, so that the positions of the fixed teeth 32 are limited by the guide teeth 22, and the fixed teeth 32 can only move axially along the tip cone 1, thereby limiting the rotation of the centering sleeve 3.
The stop collar 4 is sleeved outside the guide collar 2, as shown in fig. 5, the stop collar 4 is composed of a third collar body 41, a stop table 42 and a mounting hole 43, the third collar body 41 is of a boss structure with a hollow inside, and an internal thread matched with the second thread part 14 is arranged inside the third collar body 41.

The third sleeve body 41 is provided with a plurality of mounting holes 43 along the circumferential direction at intervals, and the mounting holes 43 are adjacent to the rear end of the third sleeve body 41 (namely one end with the large diameter of the third sleeve body 41) and can be used for mounting the inserted rod, and an operator can drive the limit sleeve 4 to rotate by applying force to the inserted rod, so that the use is convenient.
Because the centering sleeve 3 has the capability of expanding/contracting along the radial direction, when the limiting sleeve 4 drives the centering sleeve to move, the expansion/contraction of the centering sleeve 3 can be realized through the conical fit of the central through hole of the second sleeve body 31 and the first connecting column 11 so as to adapt to the supporting requirements of glass tubes with different inner diameters.
The glass tube is sleeved on the centering sleeve 3, and the glass tube can rotate along with the centering tool in the honing process, so that the uniformity of honing of the outer surface of the glass tube is ensured, the concentricity of the inner diameter and the outer diameter of the glass tube is ensured, the uniformity of the wall thickness of the glass tube is further realized, the production quality of the glass tube is greatly improved, the light penetration phenomenon caused by uneven wall thickness is reduced, and the product performance is improved.
It is understood that the centering tool can be made of one or more materials selected from 45# steel, 304 stainless steel, HT150 cast iron, cr12 die steel and aluminum, and the centering tool can be specifically determined according to actual design requirements.
