[0002] Quartz glass tubes are widely used in various fields such as electronics, chemical industry, medical treatment, scientific research and aviation due to their high performance. With the continuous development of these fields, the demand for quartz glass tubes is also increasing. In the production process of quartz glass tubes, secondary forming is an important link. Through secondary forming, the shape, size and performance of the quartz glass tube can be further adjusted to meet the specific application requirements.

[0003] CN217369573U discloses a quartz lamp tube shoulder forming and internal cleaning device. By cooperating with an external high-temperature heating flame gun through an angle shaping part, the transition shoulder of the fused connection between the thicker main lamp tube and the thinner quartz leg is uniformly inclined at an angle, improving the product processing efficiency and the product quality. The lathe chuck is provided with an oxygen delivery pipeline and a nozzle.

DETAILED DESCRIPTION

[0023] The following will be described in detail in combination with the accompanying Figures 1-5 The present application will be further described in detail.

Referring to Figure 1The bottom operation table 1 is provided with a slide rail 11, a left fixed base head 2 is arranged on the left side of the bottom operation table 1, and a right movable base head 3 is arranged on the right side of the bottom operation table 1. A moving heating forming assembly 4 for secondary processing of a quartz lamp is arranged between the left fixed base head 2 and the right movable base head 3.

[0025] The moving heating forming assembly 4 comprises a quartz lamp workbench 41 horizontally adapted to the track of the slide rail 11 and a forming assembly hand wheel 42 perpendicular to the track of the slide rail 11. The top of the left fixed base head 2 and the right movable base head 3 is provided with a chuck 5, and the chuck 5 is provided with a three-jaw lamp tube fixing device for fixing and clamping the bottom of the quartz lamp to be processed, so as to facilitate the secondary forming operation. The bottom end of the right movable base head 3 is horizontally provided with a sliding seat 32 adapted to the slide rail 11, and a right base hand wheel 33 is installed perpendicular to the horizontal plane of the slide rail 11. The right base hand wheel 33 can control the left and right movement of the sliding seat 32, so as to adjust the quartz lamp clamped on the right side during the processing according to the processing position.

[0026] Further, the chuck 5 is provided with a sealing protection structure. The chuck comprises a chuck outer wheel 56 at the outermost edge, a chuck center seat 57 at the center position, and a wheel column 58 connecting the chuck center seat 57 and the chuck outer wheel 56.

[0027] Further, the sealing protection structure is composed of a first sealing protection plate 51 and a second sealing protection plate 52. The first sealing protection plate 51 is located on the outside of the chuck, and the second sealing protection plate 52 is located on the inside of the chuck. The two sealing protection plates are oppositely arranged outside the wheel column 58, so as to wrap the originally exposed wheel column 58 in a sealed space, thereby preventing the high-speed rotation of the chuck during processing from causing harm to the human body due to accidental contact, and further preventing the high temperature generated by the moving heating forming assembly 4 from causing damage to the chuck.

[0028] Further, the first sealing protection plate 51 and the second sealing protection plate 52 are both hollow annular, and are fixedly connected by at least one sealing piece 511. The sealing piece 511 is a sector ring with equal area size. The long arc part of the sector ring is attached to the inner diameter of the chuck outer wheel 56, and the length of the short arc is attached to the outer diameter of the connecting center seat 7, so as to completely cover the gap between the chuck outer wheel 56 and the connecting center seat 7, hide the wheel column 58, and form a sealing barrier on the outer layer.

[0029] Further, a pressing strip 512 is arranged at one side edge of the sealing sheet 511, and a pressing groove 513 matched with the pressing strip 512 is arranged at the other side edge, so as to facilitate close fitting of the interface of the sealing sheet 511, a plurality of fixing holes 514 are arranged at the pressing strip 512, and a matching hole 515 is arranged at the position corresponding to the pressing groove 513, when the positions of the pressing strip 512 and the pressing groove 513 are matched, the fixing hole 514 and the matching hole 515 are on the same axis.

[0030] Further, a screw 53 is arranged in the axial gap of the fixing hole 514 and the matching hole 515 to fasten, so as to keep the interface of the sealing sheet 511 preliminarily fixed.

[0031] Further, in order to fix the sealing protection plate 51 on the chuck, a fixing hole is also arranged at the position corresponding to the wheel column 58, and the screw 53 is used to fix the sealing protection plate 51 on the wheel column 58, so as to complete the sealing of the whole chuck.

[0032] The implementation principle of the chuck protection structure of the lamp tube processing machine tool according to the embodiment of the application is as follows:

[0033] In the quartz lamp tube processing process, the moving heating forming assembly 4 moves on the slide rail 11 according to the processing requirement, and the chucks on both sides firmly clamp the two ends of the quartz lamp tube through the three-jaw lamp tube fixing device.

[0034] When the chuck rotates, due to the existence of the peripheral sealing protection structure, the harm caused by the accidental touch of the wheel column by the operator can be effectively prevented, and the direct erosion of the high temperature to the chuck structure can be prevented.

[0035] Meanwhile, the sealing protection structure also has good heat insulation performance, protects other precise components inside the machine tool from the high temperature, and improves the stability and service life of the whole machine.

[0036] The above are the preferred embodiments of the application, and do not limit the protection scope of the application, so that: all equivalent changes made according to the structure, shape, principle of the application should be covered in the protection scope of the application.
