[0022] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0025] The utility model provides Figures 1 to 3 The multi-angle welding positioning device for a quartz tube shown in the figure includes a fixed base 1, a U-shaped frame 3 is fixed to the top of the fixed base 1, a circular groove is opened in the middle of the top of the U-shaped frame 3, a rotating ring 12 is connected to the circular groove, a turntable 4 is fixed to the top of the rotating ring 12, and a plurality of fixing holes 6 are evenly distributed around the center of the top of the turntable 4. Fixed plates 5 are correspondingly installed on the fixing holes 6. The turntable 4 can be rotated inside the circular groove through the rotating ring 12.

[0026] Specifically, a motor 11 is fixed on one side of the top of the fixed base 1, a driving shaft 15 is provided on the top of the motor 11, and a matching tooth 14 is provided on the outer side of the driving shaft 15. The bottom end of the rotating ring 12 extends out of the circular groove, and a gear 13 is provided on the outer side of the extended end, and the gear 13 is meshed with the matching tooth 14.

[0027] In actual operation of the present invention, when the motor 11 is started, the gear 13 is driven to rotate via the driving shaft 15 . When the gear 13 rotates, the rotating ring 12 and the fixed plate 5 are driven to rotate.

[0028] A first pipe groove 8 is provided on one side of the top of the fixing plate 5 close to the center of the turntable 4;

[0029] When welding is required, the two quartz tubes to be welded can be placed on the first tube groove 8 in the corresponding fixing plate 5. Since the two fixing plates 5 are distributed around the center of the turntable 4, the two quartz tubes at different angles can be connected through the combination of different fixing plates 5, which facilitates the bending welding of the quartz tubes.

[0030] An electric push rod 2 is fixed to the middle of the top of the fixed base 1, and a support plate 9 is fixed to the top of the electric push rod 2. A plurality of second tube grooves 10 are provided at the top of the support plate 9. The center of the second tube groove 10 coincides with the center of the support plate 9, and the plurality of second tube grooves 10 are distributed around the support plate 9. A through groove 17 for the support plate 9 to pass through is provided in the middle of the turntable 4. The through groove 17 is set to be circular, and a distance is left between the through groove 17 and the support plate 9. Electric heating tubes are provided inside the turntable 4 and the support plate 9.

[0031] Furthermore, when the electric push rod 2 is extended upward, the support plate 9 and the fixed plate 5 can be made flush in height. By rotating the rotating ring 12, the ends of the first tube groove 8 and the second tube groove 10 can be made to correspond to each other. When two quartz tubes to be welded are placed in the two fixed plates 5 for welding, the second tube groove 10 can support the welding part and play a role of fixing and clamping.

[0032] At the same time, the two quartz tubes to be welded can also be placed inside the first tube groove 8 and the second tube groove 10 respectively for linear welding. Since the distance between the first tube groove 8 and the second tube groove 10 is relatively close, it can adapt to the welding of some shorter quartz tubes, and the support plate 9 can also heat the support area.

[0033] When two quartz tubes to be welded are placed in the first tube groove 8 and the second tube groove 10 respectively, the rotating ring 12 is rotated slightly. At this time, a slight intersection is generated between the rotating ring 12 and the support plate 9. The force generated by the intersection fixes the quartz tubes in the first tube groove 8 and the second tube groove 10, preventing the quartz tubes from moving during welding.

[0034] A through slot 16 is provided on the side of the top of the fixing plate 5 away from the first tube slot 8. The through slot 16 passes through the bottom end of the fixing plate 5, and a positioning screw 7 is provided on the fixing hole 6. The positioning screw 7 passes through the corresponding through slot 16, and a nut is provided on the outer side of the through end of the positioning screw 7, and the nut is pressed tightly against the corresponding top end of the fixing plate 5.

[0035] By changing the position of the positioning screw 7 in the through slot 16, the position of the fixing plate 5 is changed, and the distance between the fixing plate 5 and the supporting plate 9 is adjusted. At the same time, the fixing plate 5 can also be rotated to change the angle.

[0036] The top end of the driving shaft 15 is rotatably connected to the bottom end of the U-shaped frame 3 .

[0037] The above embodiments are only for illustrating the technical concept and features of the present invention. Their purpose is to enable people familiar with this technology to understand the content of the present invention and implement it accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of protection of the present invention.
