Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical automation welding equipment, in particular to a clamping tool and an electromechanical automation welding device. Background Art

[0002] Welding is a manufacturing process that uses heat, temperature, or pressure to join metals or other thermoplastic materials (such as plastics).

[0003] In the prior art, an automated welding device clamps a workpiece to be welded by a clamping tool, and then automatically performs welding by a welding gun.

[0004] However, the automated welding device needs to fix the workpiece before welding. If the welding positions of the two workpieces after fixation are not accurately aligned, the rotation angle between the two workpieces needs to be slightly adjusted. Usually, during the adjustment, the fixing component is first loosened to allow the workpiece to rotate, and then the fixing component is used to fix the workpiece after rotation. The above operation process is too cumbersome, and the workpiece is loosened and clamped multiple times, which may cause damage to the workpiece surface. Utility Model Content

[0019] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0020] Example: See Figure 1 , Figure 2 A clamping tool comprises an operating plate 1, a through slot 4 is formed on the surface of the operating plate 1, and both ends of the through slot 4 are respectively connected to fixing components.

[0021] Two groups of fixed components are symmetrically arranged in the through groove 4, and the fixed components include a rotating plate 5, which is rotatably connected to the operating plate 1. Specifically, the operating plate 1 is fixedly connected with an extension column 7, and the extension column 7 has a mounting hole. The center of the rotating plate 5 is fixedly connected with a rotating shaft, which is inserted into the mounting hole and rotatably connected to the mounting hole.

[0022] The rotating plate 5 is fixedly connected to the supporting plate 3, and two symmetrical mounting plates 11 are fixedly connected to the supporting plate 3. The two mounting plates 11 are fixedly connected to the first linear drive mechanism 6, and the output end of the first linear drive mechanism 6 is connected to the clamping plate 2, and the two clamping plates 2 are symmetrically arranged relative to the rotation center of the rotating plate 5. The first linear drive mechanism 6 is a cylinder.

[0023] The through groove 4 is an I-shaped groove, the rotating plate 5 is arranged at the protruding portion of the end of the I-shaped groove, and the diameter of the rotating plate 5 is greater than the width of the middle portion of the through groove 4 .

[0024] In the above structure, the two first linear drive mechanisms 6 on the same supporting plate 3 operate synchronously, so that the two clamping plates 2 are simultaneously close to or away from the rotation center axis of the rotating plate 5. The two clamping plates 2 are used to clamp the workpieces on the supporting plate 3. Especially for regular cylindrical workpieces, the two clamping plates 2 can make the center of the clamped workpiece concentric with the rotation center of the rotating plate 5.

[0025] Two sets of locking components are provided at the lower part of the operating panel 1, and the two sets of locking components correspond to the two sets of fixing components one by one. The locking components include a second linear drive mechanism 8, which is fixed to the lower surface of the operating panel 1, and the second linear drive mechanism 8 uses a cylinder. A connecting rod 10 is fixedly connected to the output end of the second linear drive mechanism 8, and a top holding block 9 is fixedly connected to the connecting rod 10. The top holding blocks 9 of the two sets of locking components correspond to the two rotating plates 5 one by one, and the top holding blocks 9 can fix and lock the rotating plates 5.

[0026] Specifically, the upper surface of the supporting block 9 is an arc-shaped surface, on which teeth are arranged, and the rotating plate 5 is a circular plate, and the outer surface of the rotating plate 5 is provided with tooth grooves matching the teeth of the supporting block 9. The distribution density of the teeth and the tooth grooves can determine the positioning accuracy of the rotating plate 5, and the teeth and the tooth grooves can be processed according to the required accuracy.

[0027] The utility model also includes an electromechanical automated welding device, which includes the above-mentioned clamping tool, a welding gun and a workbench. The four corners of an operating panel 1 of the clamping tool can be fixedly connected with columns, and the operating panel 1 of the clamping tool is fixedly connected to the workbench through the columns. The welding gun can be a handheld welding gun or an existing automated welding gun structure.

[0028] The utility model is suitable for workpieces with cylindrical structures, especially for cylindrical workpieces with a specific diameter, and is suitable for welding large quantities of workpieces, and belongs to a special tooling. When in use, two workpieces to be welded are placed on the top of two supporting plates 3 respectively. The height of the supporting plate 3 relative to the center of the rotating plate 5 has been preset according to the diameter of the workpiece, so that the center of the workpiece in the height direction can be at the same height as the rotation center of the rotating plate 5, and then the end faces of the two workpieces to be welded are fitted to each other, and the two first linear drive mechanisms 6 on the same supporting plate 3 are synchronously driven to drive the two clamping plates 2, and the two clamping plates 2 fix the workpieces and ensure that the workpieces with cylindrical structures are concentrically arranged with the rotating plate 5. After the two workpieces are fixed on the two supporting plates 3 respectively, there may be a deviation in the alignment of the welding points of the workpieces. At this time, a small rotation adjustment of one of the workpieces is required. Specifically, the second linear drive mechanism 8 corresponding to the workpiece drives the connecting rod 10 to move downward, so that the supporting block 9 is no longer in contact with the outer surface of the rotating plate 5, so that the rotating plate 5 can rotate. The rotating plate 5 is manually driven to rotate, and the supporting plate 3 and the workpiece on it follow the rotation. The angle of the workpiece is slightly adjusted, and it is observed that the two workpieces are completely aligned. At this time, the adjustment is completed, and the second linear drive mechanism 8 is used again to drive the connecting rod 10 to move upward, so that the supporting block 9 is locked on the outer surface of the rotating plate 5, and the teeth on the surface of the supporting block 9 are stuck in the tooth grooves on the outer surface of the rotating plate 5, thereby fixing and locking the rotating plate 5, so that the position of the workpiece is fixed, and then the welding gun is used to perform welding operations on the two workpieces.
