Description

Technical Field

[0001] The present application relates to the field of component welding, and in particular to a hydraulic assembly tool for welding automobile components. Background Art

[0002] The automotive parts industry provides corresponding parts products for the automobile manufacturing industry. It is the foundation of the development of the automobile industry and an important part of the automobile industry chain. Auto parts generally refer to all parts and components except the automobile frame. Parts refer to single components that cannot be disassembled; components refer to the combination of parts that realize a certain action or function. Components can be a single part or a combination of multiple parts.

[0003] For example, the Chinese patent publication number is CN117583792A, and the technical solution disclosed in the patent document is as follows: an automatic welding device for automobile parts processing, which relates to the field of automobile parts processing technology. The key points of its technical solution include a workbench, a lifting mechanism, a clamping mechanism and a welding mechanism; the clamping mechanism includes a bracket, a turntable, a first motor and a driving assembly, and two brackets are provided and are respectively located in corresponding through grooves. Turntables are respectively connected to the side walls of the two brackets that are close to each other, and one of the turntables is driven to rotate by the first motor; when the driving assembly drives the two brackets to approach each other, the two turntables can clamp the two shaft parts on the lifting mechanism, and the turntable is driven to rotate by the first motor, so that the turntable can drive the shaft parts to rotate.

[0004] The existing technology has the following problems: When multiple lifting rollers of the above-mentioned device move toward the center at the same time, the multiple lifting rollers can clamp the shaft parts, thereby lifting the shaft parts that need to be welded, making it easier for the clamping mechanism to drive the shaft parts to rotate. However, the height of the lifting frame is unchanged. When the height of the shaft parts is different, the positions of the various lifting rollers and the center of the parts will be different. Then the lower lifting roller will contact the parts first, and the other two lifting rollers have not yet contacted the parts, so the parts are at risk of falling. Summary of the Invention

[0028] The inner wall of the mounting frame 63 is fixedly connected to a spring A615, the bottom of which is fixedly connected to the top of the moving block A64. The spring A615 applies a certain amount of pressure to the moving block A64 to ensure its stability in a stationary state, and to enable it to reset in time after the movement is completed. The end of the sliding shaft 67 away from the moving rod 66 is slidably connected to the inside of the inclined groove 616. With the cooperation of the sliding shaft 67 and the inclined groove 616, the vertical movement of the sliding shaft 67 can be converted into the lateral movement of the connecting plate 613.

The guide rail 614 is slidably connected to the inside of the sliding groove. The arrangement of the guide rail 614 and the sliding groove ensures the stability of the movement of the tooth plate 612 and the connecting plate 613.

[0029] When in use, first place the two circular workpieces on the upper ends of the placement seats 2 on both sides respectively, and then start the electric push rod 61 to drive the mounting plates 62 on both sides to descend, then the mounting frame 63 on the upper end of the mounting plate 62 and the moving block A64 inside the mounting frame 63 move downward, and then the pressure roller A65 connected to the outer wall of the moving block A64 will also descend. When the pressure roller A65 contacts the upper end of the workpiece, since the bottom of the workpiece is supported by the placement seat 2, the mounting plate 62 continues to descend, and the moving block A64 will squeeze the spring inside the mounting frame 63 and slide upward, and then the moving rod 66 at the bottom of the moving block A64 will move accordingly, and then the moving rod 66 will drive the sliding shaft 67 of its outer wall to slide upward, and at the same time, since the sliding shaft 67 is slidably connected to the inside of the inclined groove 616 opened on the outer wall of the connecting plate 613, when the sliding shaft 67 slides upward, the connecting plate 613 will move toward the gear 611, and then the connecting plate 613 will The toothed plate 612 at the bottom is driven to slide on the outer wall of the guide rail 614, and the gear 611 meshing with the toothed plate 612 will also move accordingly, and the gear 611 will drive the threaded rod 69 on its inner side to rotate, and then the moving block B610 threadedly connected to its outer wall will slide to the upper end inside the accommodating groove 68, and then the moving block B610 will drive the pressure roller B617 to rise until it contacts the bottom of the workpiece, thereby fixing the workpiece, and then the hydraulic cylinder 4 can be started to drive the electric turntable 5 to move toward one end of the workpiece. After the electric turntable 5 contacts the workpiece, the workpieces on both sides are docked together, and then the workpieces can be welded. At the same time, the workpiece can be driven to rotate by the electric turntable 5 to realize the entire welding process. After welding is completed, the electric turntable 5 is reset, and when the electric push rod 61 drives the mounting plate 62 to rise, the moving block A64 will reset under the action of the spring A615, and then the moving block B610 will also reset under the same principle.

[0030] Example 2, please refer to Figure 1-Figure 7On the basis of Example 1, the upper end of the base plate 1 is equipped with an adjustment assembly 7, which includes a connecting rod 71. The connecting rod 71 is fixedly connected to the side of the moving block A64. The other end of the connecting rod 71 is fixedly connected to the connecting rod A72. A through groove is provided on one side of the mounting frame 63. The connecting rod A72 is slidably connected to the inner wall of the through groove. The other end of the connecting rod A72 is hinged to the connecting rod B73. The outer wall of the moving block B610 is fixedly connected to the connecting rod C74. The other end of the connecting rod C74 is hinged to the connecting rod D75. The other ends of the connecting rods C74 and D75 are hinged to form a T-shaped Block 76, a movable plate 77 is provided at the upper end of the base plate 1. A T-shaped slot 78 is provided on the front of the movable plate 77. The T-shaped block 76 is slidably connected to the inside of the T-shaped slot 78. The upper end of the base plate 1 is rotatably connected to the mounting shaft 79. The outer wall of the mounting shaft 79 is fixedly sleeved with a rotating plate 710. The upper end of the rotating plate 710 has a movable slot 711. The side of the movable plate 77 is fixedly connected to the linkage shaft A713. The upper end of the base plate 1 is provided with a sliding plate 717. The upper end of the sliding plate 717 is fixedly connected to the linkage shaft B714.

Since the lengths of the connecting rods B73 and B73 are fixed, the T-shaped block 76 hinged at the other end of the connecting rod B73 and the connecting rod D75 will approach or move away from the mounting plate 62. Since the T-shaped block 76 is slidably connected to the inside of the T-shaped slot 78 opened on the front of the moving plate 77, the moving plate 77 will slide on the upper end of the slide rail B718. When the distance between the connecting rod B73 and the connecting rod D75 is close, the diameter of the surface workpiece is small, and conversely, when the distance is far, the workpiece is The diameter is relatively large. When the movable plate 77 approaches the mounting plate 62, the linkage shaft A713 on its side will move accordingly. At the same time, since one end of the linkage shaft A713 is slidably connected to the inside of the movable groove 711 on one side of the rotating plate 710, the linkage shaft A713 will drive the rotating plate 710 and the mounting shaft 79 to rotate, and the linkage shaft B714 at the upper end of the sliding plate 717 is slidably connected to the inside of the movable groove 711 on the other side of the rotating plate 710. When the rotating plate 710 rotates, the sliding plate 717 will be driven by the linkage shaft B714 to move in the direction of the movable plate 77 at the upper end of the slide rail A716, and then it can drive the position of the linear module 715 at the upper end of the sliding plate 717 and the movable plate 81 and the welding gun 82, so that the distance between the welding gun 82 and the workpiece can be adjusted according to the diameter of the workpiece.
