[0029] The working principle of the auxiliary forming device for quartz crucible production is as follows: the auxiliary forming device for quartz crucible production is mainly used to conveniently transport the quartz crucible to the specified position by the rotating roller conveying mechanism and manpower, the position of the crucible is calibrated and fixed by the clamping mechanism, the length adjusting mechanism can adjust the position of the polishing roller according to the size of the crucible, so that both polishing roller assemblies can contact the edge of the crucible, then the polishing roller 12 is driven to rotate by the motor two 13, at the same time, the polishing roller 12 is driven to move downward to contact the burr of the crucible by the electric push rod 3, the upper edge of the crucible is polished, then the crossbeam 6 and the polishing roller assembly 8 at both ends are rotated by the motor 5, and the upper end surface of the entire crucible is polished.

[0030] In the embodiment, as a preferred technical solution, the polishing roller assembly 8 includes a frame 11 fixedly arranged at the end of the telescopic link 7, the polishing roller 12 is rotatably arranged in the frame 11, and the motor two 13 is fixedly arranged outside the frame 11 to drive the polishing roller 12 to rotate.

[0032] The working process of the auxiliary forming device for quartz crucible production is as follows:

[0033] 1. First, the demolded quartz crucible 20 is placed on the rotating roller conveying mechanism on the bottom table 1. The quartz crucible is pushed smoothly into the U-shaped frame 2 by manpower.

[0034] 2. When the crucible reaches the vicinity of the designated position, the clamping mechanism is started. Two electric push rods 16 are simultaneously operated synchronously, the electric push rods 16 push the V-shaped clamping plate 17 to move towards the quartz crucible, the quartz crucible is clamped and fixed from both sides, and the position of the quartz crucible is calibrated under the cooperation of the V-shaped clamping plate and the rotating roller conveying mechanism, so that the quartz crucible is located in the center of the polishing work, the accuracy of polishing is improved, and displacement of the quartz crucible during polishing is prevented.

[0035] 3. According to the size specification of the crucible, the position of the polishing roller assembly 8 is adjusted.
