Embodiment 1

[0032]Such asfigure 1 ,figure 2 In the illustrated embodiment 1, a quartz tube expanding device includes a bed 1, a chuck 11 arranged on the bed 1 for clamping both ends of the quartz tube, and a pipe expanding mechanism, the chuck 11 is a three-jaw card The tube expansion mechanism includes a supporting roller 2, a cooling water tank 6, a lifting mechanism 3, and a welding gun (not shown in the figure) for supporting the quartz tube 7. The supporting roller 2 is made of graphite, and the supporting roller 2 is rotated and arranged in the cooling In the water tank 6, the axis of the supporting roller 2 is parallel to the axis of the quartz tube 7 and is set directly below the quartz tube 7. The bottom of the cooling water tank 6 is provided with a lifting mechanism 3, and the bottom of the lifting mechanism 3 is slidably connected to the bed 1, and the lifting mechanism 3 can Move along the length of the quartz tube 7.

[0033]Such asfigure 2 As shown, the lifting mechanism 3 includes ...

Embodiment 2

[0037]Such asimage 3 In the illustrated embodiment 2, a quartz tube expansion device has roughly the same structure as that of embodiment 1, except that the cooling water tank 6 includes an inner tank 61 and an outer tank 62 sleeved outside the inner tank 61, and a supporting wheel 2 It is rotatably arranged in the inner groove 61. The side wall of the inner groove 61 is provided with a first through hole 611 communicating with the outer groove 62. The two ends of the rotating shaft of the supporting wheel 2 extend outward, and the rotating shaft is provided with an adjusting plate spaced apart from the supporting wheel body. 22. The adjusting plate 22 is provided with a second through hole 21 corresponding to the first through hole 611 and communicating with the inner groove 61, and the supporting wheel 2 switches the communication state of the inner groove 61 and the outer groove 62 by rotating.

[0038]When expanding the tube, inject cold water into the inner tank and ice water into...

Abstract

A quartz tube expanding device comprises a lathe bed, a chuck and a tube expanding mechanism, wherein the chuck and the tube expanding mechanism are arranged on the lathe bed and used for clamping twoends of a quartz tube, the tube expanding mechanism comprises a riding wheel and a lifting mechanism, the riding wheel is used for supporting the quartz tube, and the lifting mechanism is arranged onthe lathe bed below the riding wheel. The lifting mechanism is connected with an electric driving mechanism through a transmission mechanism, and the electric driving mechanism drives the lifting mechanism to drive the riding wheels to ascend and descend from the exterior of the lathe bed. The invention has the following beneficial effects: (1) by arranging the external driving mechanism, the influence of high temperature on the performance of the driving mechanism is avoided; (2) the height adjusting precision of the pipe expanding mechanism is high; (3) by arranging a movable motor, the movement limitation of the pipe expanding mechanism is avoided; (4) the cooling effect of the riding wheel is ensured by arranging the inner and outer cooling tanks, and the pipe expanding effect is good; and (5) the automatic control accuracy is high, the application range is wide, and the tube expanding quality guarantee can be provided for various types of quartz tubes.

Description

Technical field[0001]The invention relates to the technical field of quartz processing, in particular to a quartz tube expanding device.Background technique[0002]Quartz glass has a series of characteristics such as high hardness, high purity, low thermal expansion coefficient and electrical insulation, so its processing technology requirements are very strict. In particular, most of the fine sintering and expansion processes are traditional manual operations. The qualification rate and efficiency of sintering are It is generally low, and requires a high level of skill for the operators. At present, there is a semi-automatic pipe expanding machine on the market, including a bed and a clamping and rotating mechanism set on the bed. The bed is equipped with a lifting and lowering pipe expanding mechanism. The quartz tube is clamped by the clamping and rotating mechanism to roughly adjust the axis of the quartz tube. Position, the expansion mechanism slowly rises, after touching the bot...
