Description

Technical Field

[0001] This utility model relates to the technical field of fin welding, and in particular to a positioning device for fin welding of a gas energy saver. Background Technology

[0002] A gas-fired energy saver is a device that improves boiler efficiency by recovering waste heat from flue gas. Its core component is a heat exchange tube bundle consisting of multiple base tubes and a large number of fins welded onto the base tubes.

[0003] Existing gas economizer fin welding positioning devices, such as the condenser fin welding positioning fixture disclosed in utility model patent application number 202421806256.7, mainly include a worktable connecting shaft, which is rotatably connected to the worktable. The positioning table is fixedly connected to the connecting shaft, and the sliding block is slidably connected inside the positioning table. In use, turning the handwheel can drive the transmission worm gear to rotate synchronously through the second transmission shaft. The rotation of the transmission worm gear will drive the third transmission shaft and the connecting shaft to rotate through the worm gear transmission mechanism formed by meshing with the transmission worm wheel. This causes the positioning table and the condenser body to rotate, allowing the welder to conveniently weld the fins and other components on the condenser body at multiple angles without moving their position.

[0004] However, most existing welding positioning devices require repeated manual measurement and adjustment, which can easily lead to uneven fin spacing, affecting heat exchange efficiency and aerodynamic performance. Moreover, most positioning devices are fixedly installed, which can easily affect the welding angle, and subsequent manual welding is very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a gas energy-saving fin welding positioning device that not only facilitates the adjustment and positioning of the fins to ensure consistent fin spacing, but also facilitates the adjustment of the positioning position, improves the flexibility of the device, and avoids affecting the welding process.

[0006] This utility model discloses a gas economizer fin welding and positioning device, including a support mechanism; it also includes a clamping mechanism, a moving mechanism, multiple sets of adjustment mechanisms, and multiple sets of positioning mechanisms. The clamping mechanism is installed on the support mechanism and fixes the gas economizer. The moving mechanism is installed on the support mechanism and facilitates adjustment of the positioning position. The multiple sets of adjustment mechanisms are slidably installed on the moving mechanism and facilitate adjustment of the spacing. The multiple sets of adjustment mechanisms are respectively installed on the multiple sets of positioning mechanisms and fix the fins. The operator places the gas economizer on the support mechanism, the clamping mechanism positions and fixes the gas economizer, then slides the multiple sets of adjustment mechanisms to adjust the spacing, and the multiple sets of positioning mechanisms are adjusted to a suitable height to facilitate fixing the fins and facilitating welding of the fins to the gas economizer. The moving mechanism can drive the multiple sets of adjustment mechanisms and multiple sets of positioning mechanisms to move and adjust the positioning position to facilitate welding.

[0007] Preferably, the support mechanism includes a workbench, a back plate, three sets of first electric cylinders, and a positioning plate. The bottom end of the workbench is connected to the ground, and the bottom end of the back plate is connected to the top end of the workbench. The back plate has a groove, and the three sets of first electric cylinders are installed in the groove of the back plate. The positioning plate is installed on the output end of the three sets of first electric cylinders. The operator places the gas economizer on the workbench, with one side against the back plate, and then starts the three sets of first electric cylinders to push the positioning plate to position the bottom end of one side of the fins.

[0008] Preferably, the clamping mechanism includes a servo motor, a reducer, a bidirectional lead screw, two sets of sliders, two sets of clamping plates, and a telescopic sleeve. A positioning groove is provided on the worktable. The servo motor is mounted on the reducer, and the output end of the servo motor is connected to the input end of the reducer. The output end of the reducer is connected to the input end of the bidirectional lead screw. Both sets of sliders are slidably mounted in the positioning groove of the worktable and connected to the bidirectional lead screw via threaded transmission. The two sets of clamping plates are respectively mounted on the two sets of sliders, and the telescopic sleeve is mounted on the bidirectional lead screw. When the servo motor is started, it drives the bidirectional lead screw to rotate through the reducer. The bidirectional lead screw drives the two sets of sliders closer together, facilitating the clamping plates to clamp and fix the gas energy saver, ensuring that the gas energy saver is located in the middle position of the worktable. The telescopic sleeve prevents welding debris from falling into the positioning groove and affecting the transmission effect of the bidirectional lead screw.

[0009] Preferably, the moving mechanism includes two sets of electromagnetic guide rails, two sets of electromagnetic sliders, a crossbeam, and a controller. Both sets of electromagnetic guide rails are mounted on the worktable, and the two sets of electromagnetic sliders are slidably mounted on the two sets of electromagnetic guide rails respectively. The crossbeam is connected and mounted between the two sets of electromagnetic sliders, and a sliding groove is opened on the crossbeam. The controller is mounted on the electromagnetic sliders. The operator controls the start and stop of the servo motor and the movement of the two sets of electromagnetic sliders on the two sets of electromagnetic guide rails through the controller, which facilitates the adjustment of the fixed position of the fins and facilitates the welding of the operator.

[0010] Preferably, the crossbeam is also marked with a scale; by setting the scale, it is convenient to determine the spacing of multiple sets of adjustment mechanisms to ensure that the spacing of the fins is the same.

[0011] Preferably, the adjustment mechanism includes a positioning block, a fixing bolt, a shim, and a pointer. The positioning block is slidably installed in the sliding groove of the crossbeam, the fixing bolt is installed on the positioning block and connected to the positioning block by a threaded drive, the shim is slidably installed on the fixing bolt, and the pointer is installed on the positioning block. The operator operates the fixing bolt to drive the positioning block to slide, and uses the pointer to compare with the scale to make the positioning block position accurate. Then, the operator screws the fixing bolt, which presses the shim to fix the positioning block.

[0012] Preferably, the positioning mechanism includes a second electric cylinder, a connecting frame, and a fixed wheel. The top end of the second electric cylinder is connected to the bottom end of the positioning block, and the top end of the connecting frame is connected to the bottom end of the second electric cylinder. The fixed wheel is rotatably mounted on the connecting frame. The second electric cylinder pushes the connecting frame and the fixed wheel down, which facilitates the fixed wheel to press the fins. When the crossbeam moves, it drives the fixed wheel to roll on the fins to avoid friction with the fins.

[0013] Preferably, the surface of the fixing wheel is covered with a rubber pad; by laying the rubber pad, not only can wear between the fixing wheel and the fin be avoided, but the fixing effect on the fin is also enhanced.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator places the gas energy saver on the support mechanism, the clamping mechanism positions and fixes the gas energy saver, and then the sliding adjustment mechanism adjusts the spacing, and the multiple positioning mechanisms are adjusted to a suitable height to facilitate the fixing of the fins. This makes it convenient for the operator to weld the fins to the gas energy saver. The moving mechanism can drive the multiple adjustment mechanisms and multiple positioning mechanisms to move, and adjusting the positioning position facilitates welding. Attached Figure Description
