[0025] In the above technical solution, the bottom plate 1 is the basis of the whole tooling, used for bearing and positioning the workpiece to be welded. The first positioning part 31 is used to provide an accurate positioning reference for the subsequent pushing part 33. The pushing part 33 is used to push the workpiece to be welded towards the first positioning part 31, ensuring the close contact between the workpiece and the first positioning part 31. Through the cooperation of the pushing part 33 and the first positioning part 31, the workpiece to be welded is clamped and accurately positioned, thereby improving the positioning accuracy and reliability. The fixing assembly 4 is used to provide additional pressing force to the workpiece to be welded after the pushing part 33 completes the preliminary clamping and positioning, ensuring that the workpiece does not move during the entire welding process, thereby improving the welding quality and ensuring the consistency of the welding. The welding positioning tool proposed in the utility model realizes accurate positioning and firm fixing of the workpiece by setting the positioning assembly 3 and the fixing assembly 4, effectively overcomes the workpiece deformation and displacement problem in the welding process, thereby improving the welding efficiency and welding quality, and ensuring the consistency of the welding, and solving the problem of poor welding consistency and low welding efficiency.

[0026] In one embodiment, the positioning assembly 3 further comprises a second positioning part 32, and the second positioning part 32 is arranged on the side of the clamping and positioning space away from the first positioning part 31.

[0027] In the above technical solution, the main function of the second positioning part 32 is to provide preliminary positioning for the workpiece, so that the workpiece to be welded can quickly and accurately enter the clamping and positioning space, and prepare for subsequent clamping and positioning. The second positioning part 32 is arranged on the side of the clamping and positioning space away from the first positioning part 31, so that the second positioning part 32 cooperates with the first positioning part 31 to coarsely position the workpiece from both sides of the clamping and positioning space. Compared with the single-sided positioning method with only the first positioning part 31, the positioning accuracy and efficiency are further improved. By setting the second positioning part 32, the efficiency and effect of clamping and positioning the workpiece are improved, thereby improving the welding efficiency.

[0028] In one embodiment, the pushing part 33 comprises a first driving part 331 and a pushing piece 332, the first driving part 331 is arranged on the bottom plate 1, and the pushing piece 332 is drivingly connected with the first driving part 331.

[0029] In the above technical solution, the first driving part 331 is the power source of the pushing part 33, and is usually a cylinder, a hydraulic cylinder or an electric actuator as a driving element. The first driving part 331 is fixed on the bottom plate 1, and generates a linear or rotary driving force through the movement of the piston inside or the rotation of the motor, and then directly or indirectly drives the pushing piece 332 to complete the action. The pushing part 33 is connected to the output end of the first driving part 331, the pushing piece 332 is in direct contact with the surface of the workpiece to be welded, and the pushing piece 332 has a large contact area with the surface of the workpiece, so as to avoid damaging the surface of the workpiece during pushing. The pushing piece 332 is driven by the first driving part 331 to push the workpiece towards the first positioning part 31, so that the workpiece is in close contact with the first positioning part 31, thereby accurately positioning the part to be welded of the workpiece and ensuring the precision and consistency of welding.

[0030] In one embodiment, the welding positioning tool further comprises a support part 2 and a fixing assembly 4, the support part 2 is arranged on the bottom plate 1, the support part 2 comprises a support block 21, and the fixing assembly 4 is arranged corresponding to the support block 21, and a pressure connection fixed space is formed between the fixing assembly 4 and the support block 21.

[0031] In the above technical solution, the support block 21 is located on the bottom plate 1 and provides support for the workpiece to be welded. The fixing assembly 4 and the support block 21 form a pressure connection fixed space, and after the workpiece is installed in place, the flange of the workpiece to be welded is pressed on the support block 21 by the fixing assembly 4, so as to press and fix the workpiece, thereby avoiding the movement of the workpiece caused by welding thermal stress, external force or vibration, and thus causing welding error. By adjusting the thickness of the support block 21, the height of the workpiece can also be adjusted, so that workpieces of different sizes can be located in the appropriate welding height range, thereby ensuring good welding quality and welding consistency. In addition, by arranging the support block 21, the workpiece is directly pressed and fixed on the bottom plate 1 by the fixing assembly 4, thereby avoiding the wear of the bottom plate 1, thereby prolonging the service life of the tool. Even if the support block 21 is worn out due to the pressing of the workpiece on the support block 21, the support block 21 can be conveniently replaced, thereby reducing the difficulty and cost of maintenance.

[0032] In one embodiment, the support part 2 further comprises a support rod 22, the support rod 22 is arranged on the inner circumferential side of the clamping and positioning space, one end of the support rod 22 is arranged on the bottom plate 1, and the support rod 22 extends towards the side away from the bottom plate 1.

[0033] In the above technical solution, the support rod 22 is used to support the workpiece to be welded on the inner circumferential side of the clamping and positioning space, thereby avoiding the deformation or displacement of the workpiece towards the bottom plate 1 during welding. By adjusting the position and height of the support rod 22, the welding positioning tool can adapt to machine cases of different sizes and shapes, thereby enhancing the versatility and production flexibility of the tool.

[0034] In one embodiment, the fixing assembly 4 comprises a second driving part 41 and a pressing part 42, the second driving part 41 is arranged on the base plate 1, and the second driving part 41 drives the pressing part 42 to move towards the side close to the base plate 1.

[0035] In the above technical solution, the second driving part 41 usually adopts a driving device such as a pneumatic cylinder, a hydraulic cylinder or a motor, which is used to control the movement of the pressing part 42. The pressing part 42 directly contacts the workpiece to be welded and is used to press the workpiece on the support block 21. The pressing part 42 has a large contact area with the workpiece to be welded, which avoids damaging the surface of the workpiece during pressing. Through the cooperation of the second driving part 41 and the pressing part 42, the workpiece to be welded is fixed on the base plate 1, which ensures the stable fixation of the workpiece during welding, thereby improving the welding quality and production efficiency.

[0036] In one embodiment, the base plate 1 is provided with a mounting seat 7, and the pushing part 33 is arranged on the mounting seat 7.

[0037] In the above technical solution, the mounting seat 7 mainly serves as the fixing and mounting basis of the pushing part 33, and it is designed to be firmly connected with the base plate 1 to provide stable support for the pushing part 33. At the same time, the design of the mounting seat 7 also facilitates the installation and disassembly of the pushing part 33, simplifying the maintenance and adjustment process. In addition, by adjusting the thickness or height of the mounting seat 7, the height of the pushing part 33 can be adjusted to avoid the situation that the adjacent two pushing parts 33 cannot work normally due to too close distance or overlapping position.

[0038] In one embodiment, a plurality of pushing parts 33 are arranged at intervals on the circumferential side of the clamping and positioning space, and the arrangement position of the pushing part 33 corresponds to the arrangement position of the first positioning part 31.

[0039] In the above technical solution, the arrangement of the plurality of pushing parts 33 can ensure that the pushing parts 33 apply pushing force to the workpiece to be welded evenly, avoid uneven positioning pressure caused by single-point contact, and make each key part of the workpiece be properly positioned and pressed, thereby reducing the risk of deformation of the workpiece during positioning and improving the stability and precision of positioning. The arrangement position of the pushing part 33 corresponds to the arrangement position of the first positioning part 31, so that the pushing part 33 can push the side wall of the workpiece to be welded to the position closely attached to the first positioning part 31. On the one hand, the workpiece to be welded is clamped and fixed by the clamping action between the pushing part 33 and the first positioning part 31, which avoids the movement of the workpiece during welding and causes welding error. On the other hand, the workpiece to be welded is abutted on the first positioning part 31 under the action of the plurality of points of the pushing part 33, which further improves the positioning precision of the workpiece to be welded, thereby improving the welding effect and consistency.

[0040] In an embodiment, the first driving part 331 comprises a driving cylinder or a driving motor.

[0041] In the above technical solution, the driving cylinder has the characteristics of rapid response, adjustable thrust and smooth movement, and the driving motor can adjust its speed and torque through a precise control system to achieve smooth and accurate pushing. Both the driving cylinder and the driving motor can provide stable and controllable power output to meet the requirements of rapid response and accurate control of the pushing part 33 in the welding positioning tool.

[0042] In an embodiment, the second driving part 41 comprises a rotary down cylinder, and the pressing part 42 is drivingly connected with the rotary down cylinder.

[0043] In the above technical solution, the rotary down cylinder is a pneumatic actuator that can provide downward pressure in the vertical direction and has a certain rotation function. When the rotary down cylinder is used as a power source, in the default state, the rotary down cylinder drives the pressing part 42 to move away from the support block 21 and raises the pressing part 42 to the highest point to avoid interference with the installation of the workpiece to be welded. When the workpiece is placed into the clamping and fixing space, the pushing part 33 and the first positioning part 31 clamp and fix the workpiece to be welded. At this time, the output end of the rotary down cylinder rotates to drive the pressing part 42 to rotate above the support block 21, and then the output end of the rotary down cylinder descends to drive the pressing part 42 to move along the vertical direction towards the support block 21 until the pressing part 42 contacts the workpiece to press the flange of the workpiece on the support block 21, achieving the press-fixing of the workpiece.

[0044] In an embodiment, the welding positioning tool further comprises a control system and a fixing assembly 4, the control system comprises a controller 6, the controller 6 is arranged on the bottom plate 1, the pushing part 33 comprises a first driving part 331, the fixing assembly 4 comprises a second driving part 41, and the control system is in communication connection with the first driving part 331 and the second driving part 41.

[0045] In the above technical solution, the controller 6 is used to control the operation of the action components such as the first driving part 331 and the second driving part 41. Through the controller 6, semi-automatic or full-automatic welding of the workpiece to be welded can be realized, thereby improving the welding efficiency.

[0046] In an embodiment, the workpiece to be welded is a case, and the case is buckled on the welding positioning tool during welding. The side wall of the case is abutted on the first positioning part 31 under the pushing action of the pushing part 33 to achieve clamping and positioning of the case. The pressing part 42 press-fixes the flange of the case on the support block 21 to achieve press-fixing of the case. The support rod 22 supports the bottom plate of the case on the inner circumferential side of the clamping and positioning space.

[0047] In the above technical scheme, the main welding points of the case are concentrated at the four corner edges of the case, and the arc-shaped plate at the round corner needs to be connected and fixed with the adjacent planar plate by welding. The case is buckled on the welding positioning tool proposed in the utility model, and the case is quickly and accurately positioned and firmly and reliably fixed through the first positioning part 31, the second positioning part 32 and the pressing part 42 and other components, so that the case has good welding quality and consistency, and the welding efficiency of the case is significantly improved.
