Description
Technical Field
[0001] This invention relates to a quartz product processing technology, and more specifically, to a quartz tube welding fixture and method. Background Technology
[0002] Currently, the processing of quartz tubes requires fin welding. During welding, it is necessary to ensure the coaxiality and spacing of the fins. The traditional method is to place graphite sheets of a fixed height between the fins to ensure the spacing; then, several graphite blocks are simultaneously moved radially towards the center to press and compress them to ensure coaxiality, and finally, welding is performed. This method is relatively cumbersome, uses many auxiliary parts, and the graphite blocks are prone to wear and need to be replaced regularly. Summary of the Invention
[0003] To overcome the above shortcomings, the present invention provides a quartz tube welding fixture and method, which facilitates quartz tube welding operation, reduces auxiliary parts, and improves work efficiency.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a quartz tube welding fixture, comprising a base and a plurality of support components evenly distributed on the base in the circumferential direction, the quartz tube comprising a plurality of quartz columns and a plurality of fins, the support components comprising a vertical rod and a slide mounted on the vertical rod in a lifting and movable manner, the slide being provided with a support head for supporting the fins; a plurality of vertical blocks evenly distributed in the circumferential direction are provided on the base, the vertical blocks abutting against the edge of the fins to achieve radial positioning of the fins.
[0005] The quartz tube is constructed by welding quartz pillars and fins. The fins have insertion holes, and the quartz pillars and insertion holes are inserted and then welded at the insertion points. Several circumferentially distributed vertical stops provide circumferential positioning for the fins, ensuring their coaxiality. After one fin is welded, the support assembly is moved outwards, and the slide is moved upwards, the distance matching the spacing between adjacent fins. The support assembly is then moved inwards so that the support head can support the previous fin. The next fin is then inserted between the vertical stops, with the insertion holes on the fin corresponding to the quartz pillars. The fin is then supported by the support head before welding. The slide on the support assembly can move up and down to maintain the spacing between adjacent fins. The quartz tube welding operation is convenient, reduces auxiliary parts, and improves work efficiency.
[0006] Preferably, the support components and vertical blocks are set in a one-to-one correspondence, and the vertical blocks are provided with clearance grooves for the support head to pass through.
[0007] The support components and vertical stops are paired one-to-one. During welding, the vertical stops shield the flames, preventing damage to the support components. The clearance groove facilitates the movement of the support head in and out.
[0008] Preferably, a support block is provided at the lower end of the upright, and the support block is supported on the base.
[0009] The support blocks ensure stable support for the uprights.
[0010] Preferably, a scale is installed on the upright, and a locking screw is installed on the slide block. The locking screw abuts against the upright to position the slide block.
[0011] The scale makes it easy to control the distance the slide moves. Once the slide is in place, it is locked in position by a locking screw, ensuring convenient and reliable positioning.
[0012] Preferably, the vertical stop is made of graphite.
[0013] The vertical stop block made of graphite is resistant to high temperatures and is not easily deformed.
[0014] Another option is to install several positioning pins at intervals on the upright, with the distance between two adjacent positioning pins being equal to the distance between two adjacent fins. The slide is provided with positioning holes, and the slide moves up and down to make the positioning pins spring into the positioning holes to achieve positioning.
[0015] The slide block and the upright are locked in place by positioning holes and positioning spring pins. When the slide block position is adjusted after welding one fin, simply press the positioning spring pin in the positioning hole of the slide block inward, and then slide the slide block upward so that the positioning hole on the slide block aligns with the previous positioning spring pin to achieve precise raising and lowering of the slide block. The slide block's up and down adjustment is convenient, precise, and reliable.
[0016] Preferably, a rotating ring is rotatably mounted on the base, and a movable block is provided at the lower end of the upright. The movable block is radially mounted on the base, and a push-pull connecting rod is hinged between the rotating ring and the movable block. The rotation of the rotating ring drives the movable block to move radially through the push-pull connecting rod.
[0017] Before adjusting the slide's position, the support assembly needs to be moved outwards. At this time, the rotating ring rotates, driving the moving block radially outwards via the push-pull linkage, separating the support head from the fin. After the slide is properly positioned, the rotating ring rotates in the opposite direction, moving the upright inwards, allowing the support head to support the next fin. The rotation of the rotating ring causes all support assemblies to move synchronously, eliminating the need to move them one by one, thus improving work efficiency. Furthermore, the synchronous movement of all support assemblies ensures consistent movement distance, which is beneficial for stable support of the fin.
[0018] Preferably, a handle is provided on the rotating ring, a sliding locking seat is installed on the handle, a positioning spring is installed between the locking seat and the handle, a locking pin is provided on the locking seat, and a locking hole is provided on the base corresponding to the locking pin. After the rotating ring rotates to the position, the locking pin is inserted into the locking hole.
[0019] The rotating ring is easily operated by rotating it with a handle. Once the rotating ring is in position, the locking pin, under the action of the positioning spring, inserts into the locking hole, thus positioning the rotating ring and the support assembly. As the rotating ring rotates, it pushes the locking seat outward, disengaging the locking pin from the locking hole and eliminating the positioning constraint.
[0020] A method for welding quartz cylinders, utilizing a quartz cylinder welding fixture to perform the welding operation on quartz cylinders, includes the following steps:
[0021] S1, Move the slide block to position the support head at the height of the lowest fin;
[0022] S2, insert the fins into the area enclosed by the vertical blocks so that the fins are supported on the support head;
[0023] S3, Install the quartz column. The fins are provided with corresponding insertion holes for the quartz column. The quartz column is inserted and connected to the insertion holes on the fins.
[0024] S4, Welding between the quartz post and the socket;
[0025] S5, move the upright outward to separate the support head from the fin, and move the slide block upward one position so that the support head can support the upper fin, and then move the upright inward.
[0026] S6, insert the next fin into the area enclosed by the vertical stop block so that the fin is supported on the support head and the insertion hole on the fin is inserted into the corresponding quartz column.
[0027] S7. Repeat steps S4 to S6 until all fins are welded, finally forming a quartz tube. Then, move the support assembly outward and remove the quartz tube.
[0028] During the quartz tube welding process, a welding fixture is used for positioning, and a vertical stop block achieves circumferential positioning of the fins, thus ensuring their coaxiality. A support assembly supports the fins, ensuring the spacing between adjacent fins. The welding operation is convenient, reduces auxiliary parts, and improves work efficiency.
[0029] A method for welding quartz cylinders, utilizing a quartz cylinder welding fixture to perform the welding operation on quartz cylinders, includes the following steps:
[0030] S1, the movable slide block is moved to the height position of the support head supporting the lowest fin, and the positioning spring pin on the upright is inserted into the positioning hole on the slide block to realize the positioning of the slide block;
[0031] S2, insert the fins into the area enclosed by the vertical blocks so that the fins are supported on the support head;
[0032] S3, Install the quartz column. The fins are provided with corresponding insertion holes for the quartz column. The quartz column is inserted and connected to the insertion holes on the fins.
[0033] S4, Welding between the quartz post and the socket;
[0034] S5, the rotating ring rotates and drives the moving block to move radially outward through the push-pull linkage, so that the support head is separated from the fin and the slide is moved upward, so that the positioning pin on the upright is inserted into the positioning hole on the slide to realize the positioning of the slide. Then the rotating ring rotates in the opposite direction to move the upright inward, so that the support head can support the fin.
[0035] S6, insert the next fin into the area enclosed by the vertical stop block so that the fin is supported on the support head and the insertion hole on the fin is inserted into the corresponding quartz column.
[0036] S7. Repeat steps S4 to S6 until all fins are welded, finally forming a quartz tube. Then, move the support assembly outward and remove the quartz tube.
[0037] During the quartz tube welding process, when the sliding block position is adjusted after welding one fin, simply press the positioning pin in the positioning hole of the sliding block inward, and then slide the sliding block upward so that the positioning hole on the sliding block aligns with the previous positioning pin to achieve precise lifting and lowering of the sliding block. The sliding block's up-and-down adjustment is convenient, accurate, and reliable. Before adjusting the sliding block's position, the support components need to be moved outward. At this time, the rotating ring rotates, driving the moving block radially outward through the push-pull linkage, separating the support head from the fin. After the sliding block position is adjusted, the rotating ring rotates in the opposite direction, causing the upright to move inward, allowing the support head to support the previous fin. The rotation of the rotating ring causes all support components to move synchronously, eliminating the need to move each support component individually, thus improving work efficiency. Furthermore, the synchronous movement of all support components ensures consistent movement distance, which is beneficial for stable support of the fins.
[0038] Compared with the prior art, the beneficial effects of the present invention are: (1) the quartz tube welding operation is convenient, the auxiliary parts are reduced, and the work efficiency is improved; (2) the sliding block is easy to move up and down to adjust the position, and the adjustment position is accurate and reliable; (3) the rotating ring rotates so that all support components move synchronously, instead of moving the support components one by one, which can improve the work efficiency. Moreover, all support components move synchronously, and the moving distance is consistent, which is conducive to the stable support of the fins. Attached Figure Description
