[0015] Preferably, a worm is meshingly connected to one side of the worm wheel, the worm is rotatably connected to the inner wall of the mounting platform, and a handle is fixedly connected to one end of the worm.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by placing the parts on the top of the positioning table and using the cylinder to drive the slider to move, the push rod can apply a force to the abutment block, thereby causing the locking rod to rotate around the rotating frame. In this process, the locking head of the locking rod accurately squeezes and positions the parts to prevent the parts from shifting during the welding process. After the welding is completed, the cylinder drives the slider to reset, and the elasticity of the tension spring will quickly reset the fixing rod, thereby causing the locking rod to rotate in the opposite direction. This reverse rotation causes the abutment block to push the push rod to reset, thereby releasing the positioning of the parts. The reset mechanism enables the parts to be quickly released after the welding is completed, which is convenient for subsequent processing.

[0017] 2. In the present invention, during the welding process, the worm is driven to rotate by rotating the handle, and then the worm wheel is driven to rotate. This operation causes the lifting rod to rotate, thereby affecting the rotating rod and the movable ring, and then adjusting the position of the positioning table. The precise control of the worm and the worm wheel realizes the fine adjustment of the angle of the positioning table. The angle of the positioning table can be accurately adjusted to ensure that the parts are in the ideal position during the welding process, and the accuracy and efficiency of welding are improved. It can adapt to the welding requirements of different parts and ensure a stable welding position, thereby improving the quality of the final product.

[0018] 3. In the present invention, during the welding process, when the movable rod is pressed, the support frame drives the movable frame to move, the pushing block causes the movable ring to move upward, and then drives the rotating rod to rise, and the coordinated movement of the lifting rod and the conical table avoids interference between the worm gear and the lifting rod, so that the rotating rod can rotate freely and quickly, and the fine adjustment of the worm and the worm gear further enhances the adjustment effect. When the lifting rod rises, the limit plate compresses the spring to store elastic potential energy. After the operation stops, the spring quickly returns to its original state and pushes the limit plate downward, so that the conical table and the conical groove fit closely. This coordination ensures that when the worm gear rotates, the lifting rod can rotate synchronously to achieve precise angle adjustment. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] Example 1: Reference Figure 1 - Figure 5 As shown: an automobile parts welding device with a positioning function, comprising a welding table 1, a welding piece 2 is installed on the top of the welding table 1, a positioning mechanism 3 is installed on one side of the welding piece 2, and a rotating mechanism 4 is installed at the bottom of the positioning mechanism 3; The positioning mechanism 3 includes a positioning platform 31 and a locking rod 33. A rotating frame 37 is fixedly connected to the side wall of the positioning platform 31. The inner side of the rotating frame 37 is rotatably connected to the middle part of the locking rod 33. A locking head 331 is fixedly connected to the top of the locking rod 33. Two sliders 322 are symmetrically slidably connected to the inner side of the positioning platform 31. Push rods 34 are abutted on both sides of the sliders 322. An abutment block 332 is fixedly connected to the bottom end of the locking rod 33. The pushing rod 34 is slidably connected to the positioning platform 31. A movable hole 36 is opened at the bottom end of the positioning platform 31. A tension spring 35 is installed inside the movable hole 36. A fixed rod 333 is fixedly connected to the inner side of the bottom end of the locking rod 33. The two ends of the movable hole 36 are respectively suspended from the two fixed rods 333.

[0023] One end of the push rod 34 passes through the positioning platform 31, and one end of the push rod 34 abuts against the abutment block 332. The top of both sides of the positioning platform 31 is fixedly connected with a mounting frame 321, one side of the mounting frame 321 is installed with a cylinder 32, and the output end of the cylinder 32 is fixedly connected to the slider 322.

[0024] In this embodiment, when welding automobile parts, the parts are placed on the top of the positioning platform 31, and then the slider 322 can be pushed to move by the cylinder 32, so that when the slider 322 moves, the inclined surfaces on both sides gradually push the push rod 34 to move, so that when the two push rods 34 move, they will gradually apply force to the abutment block 332, so that the locking rod 33 will rotate around the rotating frame 37 after receiving the force. During the rotation process, the locking rod 33 will use the locking head 331 at its top to squeeze and position the parts, so that the parts will not be offset during welding.

[0025] In addition, during the positioning process, the two locking rods 33 will use the fixed rod 333 at the bottom to pull the tension spring 35 inside the movable hole 36 at the same time. This causes the tension spring 35 to be stretched. After the welding is completed, the cylinder 32 drives the slider 322 to reset. At this time, the elasticity of the tension spring 35 itself can quickly reset the fixed rod 333, so that the locking rod 33 will rotate in the opposite direction. At this time, the abutment block 332 will start to push the push rod 34 in the opposite direction, so that the push rod 34 can also be reset, and the locking head 331 at the top of the locking rod 33 will no longer position the parts, ensuring that the welded parts can be quickly and accurately released, providing convenience for subsequent processing. During subsequent processing, the positioning device can be activated again, so that the parts can be accurately positioned, avoiding offset problems, and improving the overall processing efficiency and accuracy. Through this reset mechanism, not only the time for manual adjustment is reduced, but also the consistency and stability in multiple operations can be effectively guaranteed, laying the foundation for the automation of the entire production process.

[0026] Embodiment 2: Figure 6 - Figure 8 As shown, the rotating mechanism 4 includes a mounting platform 41, a worm gear 42 is rotatably connected to the inner side of the mounting platform 41, a conical groove 421 is provided at the top of the worm gear 42, a lifting rod 47 is slidably connected to the inner side of the worm gear 42, a movable ring 46 is fixedly connected to the top of the lifting rod 47, a rotating rod 43 is fixedly connected to the top of the movable ring 46, and the top of the rotating rod 43 is fixedly connected to the bottom of the positioning platform 31.

[0027] The bottom of the lifting rod 47 passes through the worm gear 42, and the bottom end of the lifting rod 47 is fixedly connected to a limit plate 471. A spring 48 is installed between the limit plate 471 and the worm gear 42, and the spring 48 is sleeved on the outer surface of the bottom end of the lifting rod 47. A conical platform 472 is installed on the outer surface of the top end of the lifting rod 47, and the conical platform 472 is clamped with the conical groove 421.

[0028] In this embodiment, during the welding process, when the direction needs to be adjusted, the operator can rotate the handle 491 to drive the worm 49 to rotate. The rotation of the worm 49 will generate a force, which is transmitted to the worm wheel 42 meshing with it. While the worm wheel 42 rotates, the lifting rod 47 is driven to rotate through the synergy between the embedded tapered groove 421 and the limit plate 471.

[0029] As the lifting rod 47 rotates, the rotating rod 43 and the movable ring 46 connected thereto also rotate together, and this rotational movement can directly affect the position of the positioning platform 31. By precisely controlling the worm 49 and the worm wheel 42, the operator can achieve synchronous adjustment of the rotating rod 43 and the positioning platform 31, so that the angle of the positioning platform 31 can be finely controlled during the adjustment process.

[0030] In addition, during the adjustment process, the lifting rod 47 not only drives the rotation of the rotating rod 43, but also enables the movable ring 46 to move along a specific trajectory under the guidance of the support frame 44. This movement can not only ensure that the cylinder 32 can move to a suitable welding position through precise control, but also further improve the accuracy and efficiency of welding by adjusting the angle of the positioning table 31.

[0031] In this way, the entire welding system can be flexibly adjusted in multiple dimensions to meet the welding requirements of different components, ensuring that during the welding process, the components can be stably and accurately maintained in the ideal welding position, thereby improving the stability of the welding process and the quality of the final product.

[0032] Embodiment 3: According to Figure 6 - Figure 8 As shown, a support frame 44 is fixedly connected to one side of the top of the mounting platform 41, and a movable rod 45 is rotatably connected to the inner side of the support frame 44, and one end of the movable rod 45 is fixedly connected to a movable frame 452. A push block 451 is fixedly connected to the inner side of the movable frame 452, and one end of the push block 451 is clamped with a movable ring 46. A worm 49 is meshedly connected to one side of the worm wheel 42, and the worm 49 is rotatably connected to the inner wall of the mounting platform 41, and one end of the worm 49 is fixedly connected to a handle 491.

[0033] In this embodiment, during the welding process, by pressing the movable rod 45, the movable frame 452 can be driven to move under the action of the support frame 44, so that under the action of the push block 451, the movable ring 46 will be driven to move upward, so as to drive the rotating rod 43 to move upward together. In this process, the lifting rod 47 drives the conical platform 472 to move upward together, and also drives the lifting rod 47 to slide relative to the worm gear 42. In this process, the conical platform 472 is no longer engaged with the conical groove 421, and the rotation between the worm gear 42 and the lifting rod 47 will not affect each other, so that the rotating rod 43 can be rotated freely, so that the rotating rod 43 can rotate quickly, and the fine adjustment of the worm 49 and the worm gear 42 can further improve the adjustment effect.

[0034] When the lifting rod 47 moves upward, the limit plate 471 will squeeze the spring 48, causing the spring 48 to be compressed and store a certain amount of elastic potential energy. This process ensures that the various components of the system maintain close contact and cooperation while the lifting rod 47 rises. When the movable rod 45 is no longer pulled, the spring 48 will quickly return to its original state due to its own elastic force, pushing the limit plate 471 to move downward.

[0035] As the limit plate 471 moves downward, the conical platform 472 will fit tightly with the conical groove 421, and this fit ensures that when the worm wheel 42 rotates, the lifting rod 47 can rotate synchronously with the worm wheel 42. Through this mechanism, the system can achieve precise adjustment of the angle of the lifting rod 47 and maintain a high degree of stability during the entire adjustment process.

[0036] In addition, the interaction between the limit plate 471 and the spring 48 not only improves the safety and stability of the operation, but also reduces the error caused by manual operation. The close fit between the conical platform 472 and the conical groove 421 ensures the overall rigidity and precision of the system, so that during the adjustment process, it can be freely operated within a wider angle range, thereby improving the accuracy of component positioning and the flexibility of operation during the processing.

[0037] The use method and working principle of the device: When welding automobile parts, first place the parts on the top of the positioning platform 31, and then drive the slider 322 through the cylinder 32. When the slider 322 moves, the inclined surfaces on both sides of it will gradually push the push rod 34 to move, so that the two push rods 34 gradually apply force to the abutment block 332, so that the locking rod 33 rotates around the rotating frame 37 after receiving the force. During the rotation process, the locking rod 33 uses the locking head 331 at its top to squeeze and position the parts to ensure that the parts will not deviate during welding.

[0038] During the positioning process, the two locking rods 33 will simultaneously pull the tension spring 35 inside the movable hole 36 through the fixed rod 333 at the bottom, so that the tension spring 35 is stretched. After welding is completed, the cylinder 32 drives the slider 322 to reset. At this time, the tension spring 35 quickly resets the fixed rod 333 through its own elasticity, so that the locking rod 33 rotates in the opposite direction. At the same time, the abutment block 332 will push the push rod 34 in the opposite direction, so that the push rod 34 is reset, and the locking head 331 at the top of the locking rod 33 will also loosen the parts, which is convenient for re-positioning during subsequent processing.

[0039] During the welding process, if the direction needs to be adjusted, the handle 491 can be rotated to drive the worm 49 to rotate, thereby applying a force to the worm wheel 42. As the worm wheel 42 rotates, the conical groove 421 and the limit plate 471 will work together to make the lifting rod 47 start to rotate. When the lifting rod 47 rotates, it will drive the rotating rod 43 and the movable ring 46 to rotate together, thereby adjusting the position of the cylinder 32. In this process, the worm 49 and the worm wheel 42 finely adjust the angle between the rotating rod 43 and the positioning table 31 through the coordinated action.

[0040] During the welding process, by pressing the movable rod 45, the movable frame 452 will be driven under the action of the support frame 44, so that the push block 451 drives the movable ring 46 to move upward, so that the rotating rod 43 moves upward. In this process, the lifting rod 47 drives the conical platform 472 to move upward, and makes the lifting rod 47 slide relative to the worm gear 42. At this time, the conical platform 472 is disengaged from the conical groove 421, and the rotation of the worm gear 42 and the lifting rod 47 no longer affects each other, so that the rotating rod 43 can be freely rotated, so that it can rotate quickly, and together with the worm 49 and the worm gear 42, fine adjustment can be achieved to improve the adjustment effect.

[0041] When the lifting rod 47 moves upward, the limit plate 471 compresses the spring 48. After the movable rod 45 stops being pressed, the elasticity of the spring 48 causes the limit plate 471 to move downward, and the conical platform 472 and the conical groove 421 are closely fitted again, so that when the worm gear 42 rotates, the lifting rod 47 can be driven to rotate together, further improving the degree of freedom of angle adjustment.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
