[0040] In this embodiment of the application, the rotating mechanism 3 includes a rotating part 31 disposed on the cantilever 24 and a rotating drive member 32 for driving the rotating part 31 to rotate, and the rotating part 31 is located below the cantilever 24.

[0041] Specifically, the material, specific structure, and size of the rotating part 31 can be selected according to actual needs. For example, the rotating part 31 is cylindrical.

The servo motor is communicatively connected to the control module, and the control module controls the rotating part 31 to rotate around the Z direction by controlling the servo motor.

[0042] In this embodiment of the application, the rotating mechanism 3 further includes a connecting structure 33, which is fixed on the rotating part 31. The connecting structure 33 is provided with a connecting part 34, which is detachably connected to the welder 4.

[0043] Specifically, the material, specific structure and size of the connecting structure 33 can be selected according to actual needs, and the material, specific structure and size of the connecting part 34 can be selected according to actual needs. This application does not specifically limit the detachable connection method between the connecting part 34 and the welder 4.

[0044] Specifically, the model, material, size, and specific structure of the welding device 4 can be selected according to actual needs.

[0045] In this embodiment, the welder 4 includes a welding head 41, and the line containing the welding head 41 forms a preset angle with the central axis of the rotating mechanism 3, such as... Figure 3 As shown.

[0046] Specifically, the preset angle is the angle formed by the welding head 41 and the Z direction (it should be noted that the central axis of the rotating part 31 is in the Z direction). For example, the welding head 41 forms a 45° angle with the Z direction. When the preset angle needs to be adjusted or corrected, the detachable fastener is removed first, the welding machine 4 is rotated to adjust the preset angle, and then the welding machine 4 and the connecting part 34 are fixed by the detachable fastener.

[0047] Specifically, the material, size, and structure of the fixing mechanism 5 can be selected according to actual needs. The fixing mechanism 5 and the welder 4 are located on the same side of the third slide rail 23. The distance between the fixing mechanism 5 and the first slide rail 21 can be set according to actual needs. Under the drive of the motion mechanism 2, the welding head 41 can move or adjust its angle at any position near the welding area of ​​the welding part 00 located on the fixing mechanism 5. The material, size, and structure of the first fastening mechanism 51, the second fastening mechanism 52, and the support platform 53 can be selected according to actual needs.

[0048] In this embodiment, the first fastening mechanism 51 includes a limiting boss 511 and a clamping member. The limiting boss 511 and the clamping member are respectively disposed on both sides of the bearing platform 53 along the Y direction. The clamping member includes a clamping part 512 and a clamping driving part 513. The clamping driving part 513 is used to drive the clamping part 512 to move closer to and away from the limiting boss 511 in the Y direction. For example, Figure 4-5 As shown.

[0049] Specifically, the material, size, and specific structure of the limiting boss 511 can be selected according to actual needs. During the welding operation, the welding part 00 is located on the bearing platform 53 and between the limiting boss 511 and the clamping part. The material, size, and specific structure of the clamping part 512 can be selected according to actual needs. The material, size, and specific structure of the clamping drive part 513 can be selected according to actual needs. For example, a cylinder is used as the clamping drive part 513. The cylinder drives the clamping part 512 to extend and retract in the Y direction, so that the clamping part 512 moves closer to and away from the limiting boss 511, thereby realizing that the clamping part 512 and the limiting boss 511 cooperate to clamp the welding part 00 located on the bearing platform 53 in the Y direction.

[0050] In this embodiment, the fixing mechanism 5 further includes a fixing limit block 6. The fixing limit block 6 and the bearing platform 53 are both fixed on the tooling base plate 54 in the fixing mechanism 5. The fixing limit block 6 is located on the side of the bearing platform 53 away from the limiting boss 511. The tooling base plate 54 is fixed on the table surface 11.

[0052] Specifically, the material, specific structure, and size of the fixing limit block 6 can be set according to actual needs. This application embodiment does not specifically limit the fixing method of fixing the clamping member to the fixing limit block 6. For example, the clamping member and the fixing limit block 6 are detachably connected. The shape and size of the clamping part 512 can be set according to actual needs. This application does not specifically limit the shape and size of the through hole 61, as long as the clamping part 512 is located in the through hole 61.

[0053] Specifically, the welded part 00 is the welding object of this application, and this application does not specifically limit the specific structure, size and material of the welded part 00.

[0054] In this embodiment of the application, the welded part 00 includes a water distributor body 01 and a water distributor fixing plate 02. The support platform 53 is used to support the water distributor body 01. The top of the limiting boss 511 is provided with a slot 5111 that is adapted to the water distributor fixing plate 02. The slot 5111 is used to fix the water distributor fixing plate 02.

[0055] Specifically, this application does not specifically limit the shape, size, and material of the main body 01 of the water distributor. For example, such as Figure 6 As shown, the main body 01 of the water distributor is a square pipe. This application does not specifically limit the number, shape, size and material of the water distributor fixing plate 02. For example, the water distributor fixing plate 02 is square in shape. When welding is required, the end of the water distributor fixing plate 02 that needs to be welded (this end has welding areas: first welding area 03, second welding area 04 and third welding area 05) is placed on the upper surface of the water distributor main body 01 (located on the support platform 53). The other end of the water distributor fixing plate 02 is placed in the slot 5111. This application does not specifically limit the depth of the slot 5111. The bottom of the slot 5111 cooperates with the upper surface of the water distributor main body 01 located on the support platform 53 to ensure that the position of the water distributor fixing plate 02 on the water distributor main body 01 is accurate.

[0056] In this embodiment, the second fastening mechanism 52 includes a pressing drive part 521, a conveying assembly 522, and a pressing arm 523. The pressing drive part 521 is fixed on the tooling base plate 54 in the fixing mechanism 5 and is located on the side of the limiting boss 511 away from the bearing platform 53. The tooling base plate 54 is fixed on the table surface 11. The pressing drive part 521 is connected to the first end 5221 of the conveying assembly 522. The pressing arm 523 is connected to the second end 5222 of the conveying assembly 522 and is located above the slot 5111.

[0057] Specifically, the material, specific structure and size of the pressure drive unit 521 can be set according to actual needs, the material, specific structure and size of the transmission component 522 can be set according to actual needs, and the material, specific structure and size of the pressure arm 523 can be set according to actual needs.

[0058] For example, such as Figure 4 and 5 As shown, the conveying assembly 522 includes a fixed post, a drive terminal, a first rigid arm, a second rigid arm, and a third rigid arm. The fixed post is fixed to the tooling base plate 54 and its top is higher than the pressing drive part 521. The drive terminal is connected to the pressing drive part 521 and can move along the Z direction under the drive of the pressing drive part 521. One end of the first rigid arm is rotatably connected to the top of the fixed post through a first rotating shaft, and the other end of the first rigid arm is rotatably connected to the pressing arm 523 through a second rotating shaft. The connection between the first rigid arm and the pressing arm 523 is spaced at a preset distance from the end point of the pressing arm 523. One end of the second rigid arm is rotatably connected to the first part of the drive terminal through a third rotating shaft, and the other end of the second rigid arm is rotatably connected to the middle area of ​​the first rigid arm through a fourth rotating shaft. One end of the third rigid arm is connected to the... The second part of the drive terminal is rotatably connected to the fifth pivot, and the other end of the third rigid arm is rotatably connected to the end of the lower pressure arm 523 away from the slot 5111 via the sixth pivot. The first part and the second part are spaced apart by a preset distance. Here, the end of the drive terminal connected to the lower pressure drive part 521 is the first end 5221, and the end of the second rigid arm and the third rigid arm connected to the lower pressure arm 523 is the second end 5222. The lower pressure drive part 521 drives the first end 5221 to move upward along the Z direction, and the second end 5222 of the transmission component 522 pushes the lower pressure arm 523 to move closer to the slot 5111, thereby realizing that the lower pressure arm 523, the bottom of the slot 5111, and the water distributor body 01 located on the support platform 53 cooperate with each other to press the water distributor fixing plate 02 onto the upper surface of the water distributor body 01 along the Z direction.

[0059] In this embodiment of the application, the device includes a plurality of fixing mechanisms 5 spaced apart along the X direction.

[0060] Specifically, the number of fixing mechanisms 5 matches the number of water distributor fixing plates 02, and the distance between adjacent fixing mechanisms 5 matches the distance between two adjacent water distributor fixing plates 02 that need to be welded, so that the distance between each pair of water distributor fixing plates 02 meets the welding requirements.

[0061] In this embodiment of the application, the device further includes a roller 7 for moving the worktable 1, and the roller 7 is disposed below the worktable 1.

[0062] Specifically, the number, material, size, and fixed position of the rollers 7 under the worktable 1 can be set according to actual needs.

[0063] Specifically, the position of the control module can be set according to actual needs. The control module controls the operation of the motion mechanism 2 and the rotation mechanism 3. For example, a 4-axis linkage interpolation motion control card is used as the control module, and the control module is set in the control box 8 on the workbench 1. The welding trajectory can be planned on the teach pendant in the control module. The teach pendant controls the operation of each drive component (first drive component, second drive component, third drive component, rotation drive component 32, clamping drive part 513 and pressing drive part 521) through the controller in the control module so that the second slide rail 22, the third slide rail 23, the cantilever 24 and the rotation part 31 are locked or stopped at any position, thereby accurately controlling the position of the welding head 41.

[0064] Specifically, during the welding operation, the main body 01 of the distributor is first placed on the support platform 53, with the end of the distributor fixing plate 02 to be welded located on the upper surface of the main body 01. The other end of the distributor fixing plate 02 is placed in the corresponding slot 5111. The operation control module controls the clamping drive unit 513 to drive the clamping part 512 to move towards the distributor body 01 until it works together with the limiting boss 511 in the Y direction to clamp the distributor body 01. The operation control module controls the pressing drive unit 521 to drive the first end 5221 to move upward, and the second end 5222 moves upward under force and pushes the pressing arm 523 downward until it presses the distributor fixing plate 02, thereby clamping and fixing the distributor body 01 and the distributor fixing plate 02 at one time. The operation control module controls the motion mechanism 2 and the rotation mechanism 3 to accurately position the welding head 41, thereby completing the continuous welding operation and ensuring the assembly. Precision; and the synchronous rotation of the welding head 41 during movement ensures the continuity of the weld. The U-shaped weld (composed of the first welding area 03, the second welding area 04, and the third welding area 05) has a beautiful appearance and is firmly welded. There is no need to pre-fix multiple distributor fixing plates 02 to the distributor body 01 by spot welding. The distributor body 01 and multiple distributor fixing plates 02 can be clamped on the same device at one time to complete continuous welding, which simplifies the welding process, improves work efficiency, and ensures the spacing and positional accuracy of the two fixing plates. The 4-axis linkage interpolation motion control card is used as the control module to control the motion mechanism 2 so that the welding head 41 can move in three mutually perpendicular directions and can rotate around the direction perpendicular to the table 11. By planning the welding trajectory on the teach pendant in the control module, the motion control repeatability is high, ensuring that the welding trajectory and welding angle are stable and reliable.

[0065] In summary, the water distributor welding device provided by this utility model, through the setting of a motion mechanism and a rotation mechanism, allows the welder to move in any of the two perpendicular X, Y, and Z directions, and the welder can rotate around the Z direction, achieving precise positioning of the welder. The fixing mechanisms set in the Y and Z directions for securing the welded parts eliminate the need for pre-spot welding to fix the welded parts, simplifying the welding process and improving production efficiency. The control module controls the motion and rotation mechanisms to adjust the position of the welder, avoiding the low positioning accuracy of manual welding operations. Through simple operation, the welder can accurately weld the welded parts located on the fixing mechanisms, improving welding quality. Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0066] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
