Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a desktop air outlet spring welding tool. Background Art

[0002] The automobile air-conditioning outlet shrapnel welding tool is an auxiliary tool specially designed for the welding operation of automobile air-conditioning outlet shrapnel. Its main function is to accurately position and fix the shrapnel during the welding process of the automobile air-conditioning outlet shrapnel, ensure that the shrapnel is in the correct position during welding, provide stable and reliable support for the welding operation, help improve the accuracy and consistency of welding, and ensure the welding quality, thereby helping the automobile air-conditioning outlet shrapnel to complete the welding assembly efficiently and with high quality, and ultimately ensure the normal production and performance of the automobile air-conditioning outlet. In the production process of the automobile air-conditioning outlet, the shrapnel is usually installed on the plastic column first, and then the plastic column is melted and cooled through hot riveting welding to form a material bag on the outside of the shrapnel to fix the shrapnel.

[0003] In the existing technology, large-scale welding equipment is usually used for hot riveting welding. Since the equipment is usually large in size, it needs to be operated in a special workshop. During the welding process, the air outlet equipped with the spring clip needs to be moved off the production line. After the spring clip is welded and fixed, it needs to be moved back to the production line for the next process, which increases the production steps and time, resulting in low production efficiency of automobile air-conditioning outlets. Summary of the Invention

[0006] Preferably, the fixing assembly includes a gear, which is fixedly connected to the rotating column, and racks are meshed and connected on the front and rear sides of the gear, and the two racks are fixedly connected to adjacent moving parts. A fixing part is fixedly connected to the bottom of the inner wall of the table mold, and two sliding grooves are provided on the surface of the fixing part. Positioning pins are slidably connected inside the two sliding grooves, and the two positioning pins are fixedly connected to the rotating column. A first spring is provided at the bottom end of the rotating column, and the first spring is located at the inner diameter of the fixing part.

[0007] Preferably, a plurality of connectors are fixedly connected to the top of the movable part, an air pump is fixedly connected to the rear side of the top of the table mold, two air pipes are fixedly provided at the output end of the air pump, the plurality of connectors are fixedly connected to adjacent air pipes, and the bottom ends of the plurality of connectors are fixedly connected to nozzles.

[0008] Preferably, the top of the table mold is slidably connected to two limit blocks, the bottoms of the two limit blocks are fixedly connected to second springs, the bottom ends of the two second springs are fixedly connected to the table mold, and the front sides of the two limit blocks are provided with triangular grooves.

[0009] Preferably, a pressing rod is provided on the front side of the two limit blocks, the front sides of the two pressing rods pass through and extend to the front side of the table mold, the two pressing rods are slidably connected to the table mold, and the top and bottom of the two pressing rods are fixedly connected to the moving block.

[0010] Preferably, an air-conditioning outlet body is provided on the top of the two workpiece seats, a plurality of fixing columns are fixedly connected to the opposite sides of the two air-conditioning outlet bodies, and a spring body is provided between two adjacent fixing columns.

[0011] Preferably, two sliding rods are fixedly connected between the left and right sides of the inner wall of the table mold, and the two sliding rods are slidably connected to adjacent racks.

[0012] Preferably, two first slide rails are fixedly connected to the top of the table mold, and the two moving parts are slidably connected to adjacent first slide rails.

[0013] Preferably, a control panel is provided on the top of the table mold, and sensors are provided on the surfaces of the two workpiece seats.

[0014] Preferably, the two limit blocks are both located at the front sides of the two second slide rails, and the two pressing rods are both tightly fitted between the adjacent limit blocks.

[0015] Working principle: The user first places the air-conditioning outlet body on the workpiece seat, and starts the equipment through the control panel on the top of the table mold. At this time, the electric push rods on the left and right sides of the top of the table mold work, pushing the moving part to slide smoothly along the first slide rail. The welding contact connected to the moving part then approaches the air-conditioning outlet body. After reaching the position, the fixed column is hot-riveted to form a material bag fixed shrapnel body. When the electric push rod pushes the moving part, the rack fixedly connected to the moving part moves linearly under the guidance of the slide rod, driving the gear to rotate, and then the rotating column fixedly connected to the gear rotates. The positioning pin at the bottom of the rotating column slides in the slide groove of the fixed part, and the rotating column will rise and fall in the fixed part, driving the pressing plate to rotate and descend, and the soft pad presses the air-conditioning outlet body to fix it; After welding is completed, the air pump sends gas to the nozzle through the air pipe through the connector to cool the welding position. If the workpiece seat needs to be replaced, the user pushes the pressing rod on the front side of the table mold to squeeze the triangular groove on the limit block. The limit block overcomes the elastic force of the second spring and moves downward, releasing the front limit of the workpiece seat, so that the workpiece seat can be removed. The surface sensor of the workpiece seat detects the placement of the air-conditioning outlet body. If it is improper or there is no product, an alarm will be triggered and welding will be stopped. The entire tooling structure cooperates to achieve efficient welding of the outlet spring piece.

[0016] The present invention provides a desktop air outlet spring welding tool. It has the following beneficial effects: 1. In the present invention, the first slide rail and the second slide rail on the top of the table mold are used to realize modular assembly of the workpiece base and the moving parts, so that the welding tooling is miniaturized and portable as a whole. The air outlet spring pieces can be directly arranged on the production line for welding, avoiding the need to transport the air-conditioning outlet body to the welding equipment for welding after assembling the spring pieces, thereby improving welding efficiency.

[0017] 2. In the present invention, the movable part is pushed to move by the electric push rods on both sides. When the movable part moves, the welding contact is attached to the fixed column on the air-conditioning outlet body. During welding, the electric push rod is used to push the welding contact to contact the fixed column on the air-conditioning outlet body, and the fixed column is hot-riveted to form a material bag to fix the shrapnel. At the same time, air is blown to the air pipe, the connecting head and the air nozzle through the air pump, so as to achieve rapid cooling of the welding position after welding is completed.

[0018] 3. In the present invention, when the electric push rods on both sides push the moving part to move, the two racks at the bottom are driven to move, thereby driving the gear to rotate. When the gear rotates, it drives the positioning pin at the bottom of the rotating column to slide in the slide groove, thereby driving the two pressing plates at the top to rotate and descend, so that the soft pads at the bottom of the two pressing plates press the air-conditioning outlet body to achieve rapid fixation. At the same time, the sensor on the workpiece seat detects the placement position of the air-conditioning outlet body. If there is no product or it is not placed in place, an alarm will be issued and welding cannot be started.

[0019] 4. In the present invention, by pressing the two pressing rods on the front side, the limit block is squeezed. At this time, the limit block squeezes the second spring at the bottom. At this time, the limit block moves downward, and the workpiece seat can be quickly disassembled by sliding the workpiece seat forward, which is convenient for replacing workpiece seats of different specifications to adapt to different models of automobile air-conditioning outlets, thereby improving the versatility of the tooling.

[0024] Specifically, the user places the air-conditioning outlet body 6 on the workpiece seat 5, and then starts the equipment through the control panel 12. The electric push rod 2 pushes the moving part 3 and the welding contact 4 to contact the fixed column 16 on the air-conditioning outlet body 6, and the fixed column 16 is hot-riveted to form a material bag fixed spring piece body 15, so that the overall welding tooling is miniaturized and portable, and can be directly arranged on the production line to weld the air outlet spring pieces. There is no need to transport the air-conditioning outlet body 6 after assembling the spring pieces to the welding equipment for welding, thereby improving welding efficiency.

[0025] See attached Figure 3 -Attached Figure 5 The fixed component includes a gear 20, which is fixedly connected to the rotating column 7. The front and rear sides of the gear 20 are meshed with racks 19. The two racks 19 are fixedly connected to the adjacent moving parts 3. The bottom of the inner wall of the table mold 1 is fixedly connected to a fixing part 21. Two slide grooves 22 are provided on the surface of the fixing part 21. The inside of the two slide grooves 22 are slidably connected with positioning pins 24. The two positioning pins 24 are fixedly connected to the rotating column 7. A first spring 23 is provided at the bottom end of the rotating column 7. The first spring 23 is located at the inner diameter of the fixing part 21.

[0026] Specifically, the electric push rod 2 pushes the moving part 3 to move, and the rack 19 fixedly connected to the moving part 3 moves accordingly. The rack 19 drives the gear 20 and the rotating column 7 to rotate. The bottom end of the rotating column 7 is set on the inner diameter of the fixed part 21, and the positioning pin 24 connected to its bottom end slides in the slide groove 22 opened on the surface of the fixed part 21. The rotating column 7 will rise and fall in the fixed part 21 while rotating, thereby driving the two pressing plates 8 to rotate and descend. Finally, the soft pad 17 at the bottom of the pressing plate 8 presses the air-conditioning outlet body 6 to achieve fixation, thereby realizing the automatic fixation of the air-conditioning outlet body 6 by the pressing plate 8. Without complicated operation, the air-conditioning outlet body 6 can be fixed quickly and stably, providing a reliable foundation for subsequent welding work, and improving the overall automation level and work efficiency of the welding tooling.

[0028] Specifically, after the welding contact 4 completes the hot riveting welding of the fixing column 16 of the air-conditioning outlet body 6, the gas generated by the air pump 9 is transported to the nozzle 28 through the two gas pipes 10, and the nozzle 28 sprays air toward the welding position to achieve timely cooling of the welding position after welding is completed, thereby improving the quality and stability of the welding part and avoiding the performance of the welding part being affected by high temperature.

[0029] See attached Figure 6 and attached Figure 7 There are two limit blocks 13 slidingly connected to the top of the table mold 1, and the bottoms of the two limit blocks 13 are fixedly connected to the second springs 26. The bottom ends of the two second springs 26 are fixedly connected to the table mold 1, and the front sides of the two limit blocks 13 are provided with triangular grooves 29.

[0030] Specifically, the user pushes the pressing rod 14 to squeeze the triangular groove 29 on the limit block 13, so that the limit block 13 moves downward to squeeze the second spring 26 at the bottom. At this time, the workpiece seat 5 can be removed by pulling the workpiece seat 5, which facilitates the disassembly or installation of the workpiece seat 5, improves the adaptability of the tooling to the air outlets of different models of automobile air conditioners, and enhances the flexibility of the tooling.

[0031] See attached Figure 6 and attached Figure 7 A pressing rod 14 is provided on the front side of the two limit blocks 13. The front sides of the two pressing rods 14 pass through and extend to the front side of the table mold 1. The two pressing rods 14 are slidably connected to the table mold 1. The top and bottom of the two pressing rods 14 are fixedly connected to the moving blocks 25.

[0032] Specifically, the user pushes the pressing rod 14, and the rear end of the pressing rod 14 squeezes the triangular groove 29 on the front side of the limit block 13, thereby driving the limit block 13 to move downward and release the limit on the workpiece seat 5, realizing its quick disassembly. When the operation is completed and the limit needs to be restored, the pressing rod 14 is released, and the second spring 26 rebounds, pushing the limit block 13 to reset and block the workpiece seat 5 to prevent the workpiece seat 5 from shaking during use. The maximum movement range of the pressing rod 14 is limited by the two moving blocks 25 on the pressing rod 14 to prevent the pressing rod 14 from separating from the table mold 1.

[0033] See attached Figure 1 and attached Figure 2An air-conditioning outlet body 6 is provided on the top of the two workpiece seats 5 , and a plurality of fixing columns 16 are fixedly connected to the opposite sides of the two air-conditioning outlet bodies 6 , and a spring body 15 is provided between two adjacent fixing columns 16 .

[0034] Specifically, the two workpiece seats 5 are used to place the air-conditioning outlet body 6, and the spring body 15 is installed on the fixing column 16. The fixing column 16 is hot-riveted through the welding contact 4 to form a material bag to fix the spring body 15.

[0035] See attached Figure 3 and attached Figure 4 Two slide bars 18 are fixedly connected between the left and right sides of the inner wall of the table mold 1, and the two slide bars 18 are slidably connected to the adjacent racks 19.

[0036] Specifically, the slide bar 18 provides a guide for the movement of the rack 19, ensuring that the rack 19 maintains a linear motion without deviation during the movement.

[0037] See attached Figure 1 and attached Figure 8 Two first slide rails 27 are fixedly connected to the top of the table mold 1, and the two moving parts 3 are slidably connected to the adjacent first slide rails 27.

[0038] Specifically, the movable part 3 can slide smoothly along the first slide rail 27, ensuring the movement accuracy of the movable part 3 under the push of the electric push rod 2, and ensuring that the welding contact 4 connected to the movable part 3 can accurately reach the position of the fixed column 16 on the air-conditioning outlet body 6 for welding operations. At the same time, it also facilitates the installation and disassembly of the movable part 3, is conducive to realizing modular assembly, and makes the overall structure of the tooling more flexible and convenient for maintenance and adjustment.

[0039] See attached Figure 1 and attached Figure 6 A control panel 12 is provided on the top of the table mold 1, and sensors are provided on the surfaces of the two workpiece seats 5.

[0040] Specifically, the control panel 12 provided on the top of the table mold 1 facilitates the user to perform various operations on the welding tooling and realizes effective management of the entire welding process. The sensors provided on the surfaces of the two workpiece seats 5 can detect whether the air-conditioning outlet body 6 is placed on the workpiece seat 5 and whether the placement position is accurate. If it is improperly placed or there is no product, the sensor feedback signal can trigger an alarm and prevent the welding operation from starting, thereby ensuring the welding quality, avoiding welding failure or defective products due to placement problems, and improving the reliability and stability of production.

[0041] See attached Figure 6 and attached Figure 7The two limiting blocks 13 are both located in front of the two second slide rails 30 , and the two pressing rods 14 are tightly fitted between the adjacent limiting blocks 13 .

[0042] Specifically, the two limit blocks 13 are located in front of the two second slide rails 30, and can play a front side limiting role on the workpiece seat 5 located on the second slide rail 30, preventing the workpiece seat 5 from accidentally sliding forward and disengaging from the second slide rail 30, ensuring that the workpiece seat 5 is stable on the second slide rail 30. When the workpiece seat 5 needs to be disassembled, the limit block 13 is pushed by the pressing rod 14 to release the front side limit of the workpiece seat 5, making it easier to disassemble. The overall design enhances the convenience and flexibility of the use of the tooling.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
