[0027] The following will be described in detail Figures 1-2 A glass rod machining clamping tool is described, comprising an inner sleeve 1, an outer sleeve 2 and a jacking part 3; both ends of the inner wall of the inner sleeve 1 are provided with flexible first limiting rings 4, a plurality of through air holes 12 are opened along the axial direction of the inner sleeve 1, one end of the outer part of the inner sleeve 1 forms a limiting part 11, the other end of the outer part of the inner sleeve 1 is provided with the jacking part 3, and the outer sleeve 2 is sleeved between the limiting part 11 and the jacking part 3; wherein, both sides of the outer sleeve 2 are sleeved with flexible second limiting rings 5, and the jacking part 3 is threadedly connected with the inner sleeve 1, so that the outer sleeve 2 can move axially along the inner sleeve 1 to extrude the second limiting ring 5 to deform, and the extruded second limiting ring 5 is tightly attached to the inner wall of the glass tube. When the glass rod needs to be machined, the stability of the glass rod needs to be ensured. In the embodiment, the first limiting ring 4 and the second limiting ring 5 are arranged, so that the tool can be stably arranged inside the glass tube to be machined, and the inner sleeve 1, the outer sleeve 2 and the jacking part 3 can facilitate the installation and disassembly of the clamping tool.

[0028] Specifically, the inner sleeve 1 is integrally constructed as a hollow tubular structure, which has a through hole structure penetrating in the axial direction inside, and the inner wall of the through hole structure extends in the axial direction, and an annular groove is opened at the position close to both ends of the inner sleeve 1, and the first limiting ring 4 is arranged in the groove and limited by the groove.

[0029] Further, the outer wall of the inner sleeve 1 is sequentially provided with a limiting part 11, an optical axis segment 14 and a threaded segment 15, the outer diameter of the limiting part 11 is greater than the outer diameter of the optical axis segment 14, so that it can limit the axial degree of freedom. The outer sleeve 2 is sleeved on the optical axis segment 14, the second limiting ring 5 is arranged at both ends of the outer sleeve 2, and the jacking part 3 is threadedly connected with the threaded segment 15, and the outer sleeve 2 can be pushed to move by rotating the jacking part 3, so as to extrude the second limiting ring 5, the second limiting ring 5 deforms under the extrusion, can realize the contact and fit with the inner wall of the glass tube, and through the contact friction of the two, realize the installation and positioning of the tool as a whole.

[0030] In the initial state, the second limiting ring 5 is in a relaxed state, at which time one end of the tool body can be inserted into the glass tube, and then the outer sleeve 2 is moved to press the second limiting ring 5 by rotating the jacking part 3. The second limiting ring 5 deforms under the pressing action and comes into contact with the inner wall of the glass tube, thereby preventing the inner sleeve 1 from rotating and improving the stability of the tool installation.

[0031] While the inner sleeve 1 is inserted into the glass tube, the glass rod is inserted into the inner sleeve 1, and the inner wall of the inner sleeve 1 is provided with a first limiting ring 4, which is tightly attached to the glass rod, thereby achieving stable installation of the glass rod and improving the stability of the tool.

[0032] The air hole 12 penetrates through the entire inner sleeve 1, which can achieve the full flow of dust and gas.

[0033] It can be understood that in the embodiment, the two second limiting rings 5 are pressed by the outer sleeve 2 to achieve stable installation of the tool body in the glass tube. The second limiting ring 5 is a flexible limiting ring, which can realize synchronous rotation with the glass tube, avoiding damage caused by relative rotation between the tool and the glass tube, and improving the quality of glass processing.

[0034] In specific settings, the number of outer sleeves 2 is not limited, which can be one or more. When there is one outer sleeve 2, a second limiting ring 5 is arranged between the outer sleeve 2 and the limiting part 11 and between the outer sleeve 2 and the jacking part 3. When there are multiple outer sleeves 2, a second limiting ring 5 is arranged between the outer sleeve 2 and the limiting part 11 and between adjacent outer sleeves 2. This way, multiple second limiting rings 5 can be arranged to increase the contact area of the second limiting ring 5 with the glass tube and improve the stability of the tool installation.

[0035] In combination with the above embodiment, the outer sleeve 2 is provided with two, one of which is provided with a second limiting ring 5 between the limiting part 11 and the two outer sleeves 2. The arrangement of the two outer sleeves 2 can achieve stable installation of the clamped tool and facilitate assembly of the clamped tool.

[0036] Specifically, the two second limiting rings 5 can on the one hand provide a stable fitting structure between the inner sleeve 1 body and the glass tube, and on the other hand make the installation of the outer sleeve 2 and the second limiting ring 5 more convenient.

[0037] In a specific embodiment, the first limiting ring 4 and the second limiting ring 5 are both made of fluorine rubber ring. By selecting the fluorine rubber ring, it has excellent high temperature resistance, chemical corrosion resistance, oil resistance, mechanical properties and anti-aging properties, which can effectively prolong the service life of the tool and reduce the maintenance cost.

[0038] It can be understood that the second limiting ring 5 in the embodiment needs to be frequently extruded and deformed. By selecting the fluorine rubber ring, it can maintain elasticity and durability under a large mechanical load.

[0039] In a specific embodiment, the jacking component 3 includes a jacking nut. The jacking nut cooperates with the threaded section 15 of the inner sleeve 1, so that the outer sleeve 2 can be pushed to move when the jacking nut is rotated.

[0040] In combination with the above embodiment, a plurality of limiting notches 13 are formed at the end of the inner sleeve 1 away from the limiting portion 11, and the plurality of limiting notches 13 are arranged along the circumference of the inner sleeve 1. When tightening the jacking component 3, an external tool such as a wrench needs to be cooperated. In the embodiment, the limiting notches 13 are arranged on the inner sleeve 1 to cooperate with the external tool such as the wrench, so as to avoid the inner sleeve 1 from rotating when the jacking component 3 is rotated.

[0041] Specifically, the jacking component 3 is tightened by a wrench. In order to prevent the inner sleeve 1 from rotating during the tightening process, another wrench is used to block the limiting notches 13, thereby avoiding the rotation of the inner sleeve 1 and achieving effective fastening of the jacking component 3.

[0042] In a specific embodiment, each limiting notch 13 corresponds to the air hole 12. The limiting notches 13 are in communication with the air hole 12, which makes the depth of the limiting notches 13 deeper, which can facilitate the tool to be clamped and improve the stability of the tool cooperation.

[0043] As Figure 1 mentioned above, in some embodiments, four air holes 12 are arranged, and the four air holes 12 are uniformly arranged along the axial direction of the inner sleeve 1. The uniformly arranged air holes 12 can realize the rapid passing of airflow and dust, and by limiting the number, the inner sleeve 1 has high structural strength.

[0044] In some embodiments, the limiting notches 13 have two structures, and the two limiting notches 13 are symmetrically arranged with respect to the axis of the inner sleeve 1. By limiting the structure of the limiting notches 13, it can cooperate with the wrench and other tools to limit the inner sleeve 1.

[0045] In some embodiments, the inner wall surface of the air hole 12 is a smooth wall surface structure, and the cross-sectional structure of the air hole 12 is a circular arc hole structure. By the circular arc hole structure and the smooth wall surface, the airflow and dust can pass quickly, and at the same time, the airflow path is optimized to avoid the dust in the gas from blocking the hole.

[0046] Specifically, the inner wall of the vent hole 12 is polished, so that the inner wall surface of the vent hole 12 is a smooth wall structure, avoiding dust adhesion and blockage of the hole.

[0047] In a specific application, the inner sleeve 1 is a stainless steel sleeve structure. The limitation of the stainless steel structure makes the overall tooling structure stronger.

[0048] Specifically, the inner sleeve 1 and the clamping part 3 are both made of 304 stainless steel. The overall structural strength is improved, and the use of 304 stainless steel enables a longer service life.

[0049] Through the description of the above embodiments, those skilled in the art can clearly understand that the embodiments enable the entire tooling to be installed inside the glass tube through the setting of the second limiting ring 5, and realize close limiting through the second limiting ring 5. The glass rod is arranged in the inner sleeve 1 and realizes limiting and centering through the first limiting ring 4, so as to improve the stability of the tooling installation and avoid damage to the glass tube by the glass rod.

[0050] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
