[0047] Please refer to Figures 1 to 4 , Figures 1 to 4 The structure schematic diagram of different perspectives of the air conditioner sheet metal part welding positioning device provided by the utility model embodiment.

[0048] The utility model embodiment provides a kind of air conditioner sheet metal part welding positioning device, comprising:

[0049] Positioning base 1 is equipped with the positioning table 11 for placing the sheet metal part 100 to be welded;

[0050] Clamp assembly 2 is set on positioning base 1 and can be lifted above positioning table 11, to realize the compression or loosening of the sheet metal part 100 to be welded;

[0051] Among them, clamp assembly 2 includes multiple movable compression sensing pieces 21, multiple compression sensing pieces 21 are used to press down multiple different positions of the sheet metal part 100 to be welded when clamp assembly 2 descends, and detect the pressure value of each pressing position;Multiple compression sensing pieces 21 are also used to move so that the pressure value of each pressing position is balanced.

[0052] In the embodiment, positioning base 1 can be a stable support structure, and its material is preferably high-strength steel, to ensure that the weight of clamp assembly 2 and the sheet metal part 100 to be welded can be borne during welding, while maintaining overall stability and precision. Positioning table 11 is a plane on positioning base 1, for placing the sheet metal part 100 to be welded. Clamp assembly 2 can effectively fix and compress the sheet metal part 100 to be welded. The lifting movement of clamp assembly 2 can be realized by transmission mechanism, to ensure the stability and accuracy of lifting. During the descent of clamp assembly 2, multiple compression sensing pieces 21 can press down together, to ensure that the sheet metal part 100 to be welded is uniformly stressed, avoiding deformation caused by uneven stress. At the same time, multiple compression sensing pieces 21 of clamp assembly 2 also have the function of detecting pressure value, which can monitor the pressure value of each pressing position in real time. Once uneven pressure is found, the position of compression sensing piece 21 can be adjusted to balance the pressure of each pressing position, so as to stably provide accurate positioning for sheet metal part 100 welding.

[0053] In an embodiment, the air conditioner sheet metal part welding positioning device further comprises:

[0054] A sensing control module 3 is arranged on the positioning base 1 and electrically connected with the pressure sensing pieces 21. The sensing control module 3 is used to monitor the pressure values of the plurality of pressure sensing pieces 21.

[0055] In this embodiment, the sensing control module 3 is used to receive a plurality of pressure values generated when the plurality of pressure sensing pieces 21 press the to-be-welded sheet metal part 100, and compare these pressure values with a preset pressure threshold. If any pressure value exceeds or is lower than the preset threshold range, the sensing control module 3 can immediately trigger an alarm signal to prompt the operator to adjust the position of the corresponding pressure sensing piece 21, so as to ensure that the plurality of pressure values can reach a balance, that is, to ensure that the to-be-welded sheet metal part 100 is subjected to uniform and appropriate pressure during the welding process. Such a design not only improves the accuracy of welding, but also effectively avoids welding defects caused by uneven pressure, thereby improving the overall production efficiency and product quality.

[0056] In this embodiment, the sensing control module 3 is provided with a display screen for real-time display of the pressure values of each pressure sensing piece 21 and the preset pressure threshold range. The operator can intuitively understand the pressure state in the current welding process by observing the data on the display screen, so as to make adjustments more quickly and accurately. In addition, the display screen also has a historical data recording function, which can store the pressure data of each welding for subsequent data analysis and quality traceability. Such a design further enhances the operability and intelligent level of the system.

[0057] In an embodiment, the positioning table 11 is provided with a plurality of positioning portions (not shown in the figure), which are used to cooperate with the notches or positioning holes (not shown in the figure) provided on the to-be-welded sheet metal part 100 when the to-be-welded sheet metal part 100 is placed on the positioning table 11.

[0058] In this embodiment, the positioning portion can be provided in the form of a protrusion (such as a positioning column) and is adapted to the pre-set notches or positioning holes on the to-be-welded sheet metal part 100, so as to achieve the preliminary positioning of the to-be-welded sheet metal part 100 on the positioning table 11 and provide a basis for the accurate fixing of the subsequent clamp assembly 2. In addition, the cooperation mode of the positioning portion and the to-be-welded sheet metal part 100 can be plug-in type, threaded connection type or magnetic attraction type, etc. The specific selection depends on the material, size of the to-be-welded sheet metal part 100 and the requirements of the welding process, so as to ensure the positioning accuracy while improving the flexibility and convenience of positioning.

[0059] In an embodiment, one end of the clamp assembly 2 is rotatably connected to one side of the positioning table 11, and the other end of the clamp assembly 2 extends to the other side of the positioning table 11. The clamp assembly 2 can rotate and lift around the one end as a rotation point.

[0060] In this embodiment, the lifting movement of the clamp assembly 2 is designed to adopt a rotary mechanism, which realizes the lifting movement of the clamp assembly 2 in the vertical direction through rotary action, thereby achieving the purpose of pressing or loosening the to-be-welded sheet metal part 100.

[0061] It should be understood that the rotary power of the clamp assembly 2 can be provided in various ways such as electrically, pneumatically or manually. The electrically driven mode can accurately control the rotation angle and speed of the clamp assembly 2, and is particularly suitable for application scenarios with high precision requirements. The pneumatic mode drives the clamp assembly 2 to rotate by means of air pressure, which has the advantages of simple structure and rapid action. The manual mode relies on manual operation, although the control accuracy is relatively low, but it does not need to rely on external power source, and the operation is more flexible. According to different application scenarios and specific needs, the most suitable rotary power mode can be selected to meet the lifting needs of the clamp assembly 2 in the vertical direction.

[0062] As shown in Figure 1 and Figure 5 In an embodiment, one side of the positioning table 11 is provided with a mounting rod 12, one end of the clamp assembly 2 is mounted on the mounting rod 12, and the clamp assembly 2 is provided with a plurality of clamp assemblies 2 distributed side by side along the axial direction of the mounting rod 12.

[0063] In this embodiment, under normal circumstances, at least two or more to-be-welded sheet metal parts 100 need to be welded on the positioning table 11. Therefore, the arrangement of multiple clamp assemblies 2 can ensure that each to-be-welded sheet metal part 100 can be stably pressed. In order to realize the orderly installation of multiple clamp assemblies 2, a mounting rod 12 is specially arranged on one side of the positioning table 11, so that these clamp assemblies 2 can be arranged along the axial direction (i.e. the length direction) of the mounting rod 12. This design not only effectively saves space, but also greatly facilitates the management and adjustment work of the operator.

[0064] It should also be understood that, in order to ensure that the clamp assembly 2 can more stably press the to-be-welded sheet metal part 100, during the design of the installation direction of the clamp assembly 2, the direction of the to-be-welded edge of each to-be-welded sheet metal part 100 placed on the positioning table 11 can be taken as a reference, and the arrangement direction of the multiple pressing sensing elements 21 on the clamp assembly 2 is aligned with the direction of the to-be-welded edge. In this way, the clamp assembly 2 can effectively press the to-be-welded edge of the to-be-welded sheet metal part 100, thereby ensuring the stability and reliability of the welding effect.

[0065] Please refer to Figure 5 , Figure 5 for Figure 1 the enlarged structural schematic view of the local part A.

[0066] In an embodiment, the clamp assembly 2 further comprises:

[0067] The lifting and pressing rod 22 is rotatably connected to the mounting rod 12 at one end and extends to the other side of the positioning table 11, and a plurality of pressing sensing elements 21 are installed side by side on the lifting and pressing rod 22.

[0068] The lifting driving element 23 is fixedly installed on one side of the positioning table 11 or the mounting rod 12, and is connected to the lifting and pressing rod 22 and used to drive the lifting and pressing rod 22 to rotate and lift.

[0069] In this embodiment, one end of the lifting and pressing rod 22 is rotatably connected to the mounting rod 12 through a rotating block 221, that is, the mounting rod 12 is a round rod, the rotating block 221 is rotatably sleeved on the mounting rod 12, and one end of the lifting and pressing rod 22 is fixedly inserted into the rotating block 221, so that the one end of the lifting and pressing rod 22 is rotatably connected to the mounting rod 12. The other end of the lifting and pressing rod 22 extends to the other side of the positioning table 11, and an operator can directly operate the other end of the lifting and pressing rod 22 to lift and lower the lifting and pressing rod 22, and the other end of the lifting and pressing rod 22 can be provided with a handle portion to facilitate the operation of the operator.

[0070] In this embodiment, a plurality of pressing sensing elements 21 are installed side by side on the lifting and pressing rod 22, and the lifting and pressing rod 22 is controlled by the lifting driving element 23 to lift and lower, so that the plurality of pressing sensing elements 21 can press or release the to-be-welded sheet metal part 100. When the pressing sensing elements 21 press the to-be-welded sheet metal part 100, the pressure sensor can detect the size of the pressing force in real time and transmit the detected pressing force data to the sensing control module 3.

[0071] In one implementation scheme of the lifting driving element 23, the lifting driving element 23 can include a fixed block 231, a telescopic rod 232, and a sliding block 233. The fixed block 231 is fixedly installed on one side of the positioning table 11 or the mounting rod 12. One end of the telescopic rod 232 is fixedly connected to the fixed block 231. The sliding block 233 is installed on the other end of the telescopic rod 232 and is slidably sleeved on the lifting and pressing rod 22. The telescopic rod 232 is used to drive the sliding block 233 to move back and forth on the lifting and pressing rod 22, and drive the lifting and pressing rod 22 to rotate and lift.

[0072] In this implementation scheme, the telescopic rod 232 is obliquely arranged and can be obliquely extended upward toward the other end of the lifting and pressing rod 22. The telescopic rod 232 is preferably an electric telescopic rod 232 or a pneumatic telescopic rod 232, and the position of the sliding block 233 on the lifting and pressing rod 22 can be accurately controlled by controlling the telescopic action of the telescopic rod 232, so as to accurately control the rotating and lifting movement of the lifting and pressing rod 22.

[0073] In this implementation scheme, the extension and retraction triggering method of the telescopic rod 232 can be manually triggered. When the operator lifts the other end of the lifting rod 22, the telescopic rod 232 automatically extends upon receiving the upward force signal, causing the sliding block 233 to tilt upwards towards the other end of the lifting rod 22. This causes the other end of the telescopic rod 232 to rise, releasing the clamping sensor 21 and thus releasing the sheet metal part 100 to be welded. Conversely, when the operator presses the other end of the lifting rod 22 downwards, the telescopic rod 232 automatically retracts upon receiving the downward force signal, causing the sliding block 233 to tilt downwards towards one end of the lifting rod 22. This causes the other end of the telescopic rod 232 to descend, pressing the clamping sensor 21 and thus clamping the sheet metal part 100 to be welded. This manual triggering method is simple and intuitive. The operator only needs to operate the lifting rod 22 up and down to control the extension and retraction of the telescopic rod 232, thereby completing the clamping and releasing of the sheet metal part 100 to be welded, improving the convenience and efficiency of the welding operation.

[0074] In this implementation, the sliding contact portion between the sliding block 233 and the lifting rod 22 can be made of wear-resistant material to reduce friction loss and extend service life. Simultaneously, to ensure stable sliding of the sliding block 233 on the lifting rod 22, a guide structure, such as a guide groove and a guide block, can be provided in this contact portion to further improve the accuracy and smoothness of sliding. Furthermore, the surface of the sliding block 233 can be lubricated, such as by applying an appropriate amount of lubricant, to further reduce the coefficient of friction and make operation smoother.

[0075] Please combine Figure 6 , Figure 6 for Figure 1 A magnified structural diagram of part B in the middle.

[0076] In one embodiment, the pressure sensing element 21 includes:

[0077] Clamping piece 211 is clamped onto lifting pressure rod 22;

[0078] A lead screw nut 212 passes through a clamping plate 211 and can be rotated to adjust the clamping force of the clamping plate 211 on the lifting pressure rod 22;

[0079] Pressure sensor 213 is located at the bottom of lead screw nut 212 and is used to press down the sheet metal part 100 to be welded when the clamp assembly 2 descends.

[0080] In this embodiment, the clamping plate 211 may include an upper clamping plate and a lower clamping plate. The upper clamping plate and the lower clamping plate clamp the lifting pressure rod 22 in the vertical direction. The lead screw nut 212 passes through the upper clamping plate and the lower clamping plate. By rotating the lead screw nut 212, the clamping tightness of the upper clamping plate and the lower clamping plate on the lifting pressure rod 22 can be adjusted.

[0081] It can be understood that when the pressure value monitored by the pressure sensor 213 installed at the bottom of the screw nut 212 exceeds or is lower than the preset threshold range, the position of the pressure sensing piece 21 on the lifting pressure rod 22 needs to be adjusted. The screw nut 212 is rotated to loosen the upper clamping piece and the lower clamping piece, at which time the pressure sensing piece 21 can be slid to the corresponding target position in the axial direction of the lifting pressure rod 22, and then the screw nut 212 is rotated again to clamp the lifting pressure rod 22 by the upper clamping piece and the lower clamping piece, so as to realize the position adjustment of the pressure sensing piece 21 on the lifting pressure rod 22, until the pressure value monitored by the pressure sensing piece 21 is within the preset threshold range.

[0082] It can be understood that the pressure sensor 213 can be designed to be elastic. When the plurality of pressure sensing pieces 21 press down on the to-be-welded sheet metal part 100, the plurality of pressure sensors 213 elastically apply pressure to different positions of the to-be-welded sheet metal part 100. The elastic pressure application mode can avoid causing excessive pressure damage to the surface of the to-be-welded sheet metal part 100. At the same time, the pressure sensor 213 can more accurately monitor the size of the pressure, so as to feed back the accurate pressure value to the sensing control module 3.

[0083] In an embodiment, the two ends of the clamping piece 211 extend outward symmetrically relative to the two sides of the lifting pressure rod 22, and the two screw nuts 212 are respectively arranged at the two ends of the clamping piece 211. The two pressure sensors 213 are respectively arranged at the bottom of the two screw nuts 212.

[0084] In this embodiment, in order to improve the stability of pressing the to-be-welded sheet metal part 100, the two ends of the clamping piece 211 are arranged to extend outward symmetrically, so as to realize the installation of the two screw nuts 212 and the two pressure sensors 213, and the two symmetrically arranged pressure sensors 213 can better monitor the pressure values at different positions of the to-be-welded sheet metal part 100.

[0085] Please refer to Figure 7 , Figure 7 To Figure 2 the enlarged structure diagram of the local C in

[0086] In an embodiment, the other side of the positioning table 11 is provided with a barb 13. The barb 13 is used to hook the other end of the clamp assembly 2 after the other end of the clamp assembly 2 is lowered.

[0087] In this embodiment, the barb 13 is rotatably installed on the other side edge of the positioning table 11. When the lifting drive 23 of the clamp assembly 2 fails, the clamp assembly 2 cannot stably press the to-be-welded sheet metal 100, the barb 13 can be rotated to avoid the space after the clamp assembly 2 is pressed to the target position, then the clamp assembly 2 is operated to press as a whole, and the barb 13 is rotated to hook the other end of the clamp assembly 2 (i.e., the barb 13 hooks the other end of the lifting press rod 22), so that the clamp assembly 2 stably presses the to-be-welded sheet metal.

[0088] In this embodiment, the material of the barb 13 is high-strength alloy steel, which can withstand a large pressure without deformation when hooking the clamp assembly 2, and further enhances the stability and reliability of the welding equipment. In addition, the rotation angle and force of the barb 13 can be adjusted according to actual needs to adapt to different specifications and thicknesses of the to-be-welded sheet metal 100, thereby improving the versatility and flexibility of the device.

[0089] In summary, those skilled in the art can easily understand that the above advantageous technical features can be freely combined and superimposed without conflict.

[0090] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any simple modification, equivalent change and modification of the above embodiment according to the technical essence of the present application still belongs to the scope of the technical scheme of the present application.
