[0002] Welding equipment refers to the equipment required to perform welding processes. Welding equipment includes welding machines, welding process equipment, and welding auxiliary tools. In the existing technology, when welding workpieces, it is generally necessary to manually hold and fix the workpieces with clamps before welding. However, this method is inefficient and cannot meet the needs of high-efficiency assembly line welding processing.

[0003] Furthermore, existing welding equipment requires manual adjustment of the welding position and angle during the workpiece transport and clamping process, which affects welding efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a stationary rotary welding fixture to solve the problems mentioned in the background art. This utility model has a novel structure. The feeding channel continuously feeds the workpiece out, which is then clamped by the clamping component and transferred to the rotating component. The bottom of the corresponding welding device drives the workpiece to rotate, thereby allowing multiple angles of the workpiece to correspond to the welding position and improving welding efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rotary welding fixture for a workstation, including a processing table. The top of the processing table has two sets of feeding channels. A clamping assembly is provided on the processing table at the outlet end corresponding to the feeding channel. The clamping assembly includes a movable slide rail, which is fixed to the processing table and parallel to the outlet end of the feeding channel. Three sets of electrically powered grippers are slidably mounted on the movable slide rail. A rotating assembly is provided on the outer side of the grippers on the processing table. The rotating assembly includes a mounting base, which is fixed to the processing table. A rotating platform is rotatably mounted on the top of the mounting base, and a core-pulling fixture is fixed to the side of the rotating platform facing the grippers.

[0006] Furthermore, a cylinder is slidably mounted on the movable slide rail, and a gripper is mounted on the extended end of the cylinder.

[0007] Furthermore, the rotating assembly also includes a servo motor, and the servo motor is fixedly mounted on the mounting base at the rear end of the rotating platform, with the output end of the servo motor fixedly connected to the rotating platform.

[0008] Furthermore, the rotating platform and the core-pulling fixture are provided with a central hole, and a core-pulling movable shaft is inserted into the back of the mounting base. The core-pulling movable shaft is inserted into the central hole of the rotating platform and the core-pulling fixture.

[0009] Furthermore, a connecting seat is provided on the back of the mounting base at the bottom of the servo motor, and the outer end of the core-pulling movable shaft is fixed inside the connecting seat.

[0010] Furthermore, a three-axis cylinder is fixed on both sides of the mounting base, and the extended end of the three-axis cylinder is fixedly connected to the connecting base.

[0011] Furthermore, a welding device is installed on the top of the machining table corresponding to the rotating assembly, and the welding head of the welding device corresponds to the top of the core-pulling fixture.

[0012] Furthermore, the two sets of feeding channels are inclined, and the outlet end of the feeding channel is located at the lowest point.

[0013] The beneficial effects of this utility model are:

[0014] 1. The gripper of this utility model approaches the outlet end of the feeding channel under the action of the electrically driven moving slide rail and clamps the fed workpiece. Then it moves along the moving slide rail to the corresponding position of the rotating component, and the cylinder at the rear end pushes the workpiece to be put on the core-pulling fixture of the rotating component.

[0015] 2. This utility model uses a three-axis cylinder to drive the connecting shaft and the core-pulling movable shaft to move, so that the core-pulling fixture supports the inner diameter of the workpiece and achieves the effect of clamping the workpiece. Then, the servo motor drives the rotating platform to rotate, and the core-pulling fixture and the workpiece rotate synchronously, facing the position of the top welding device. The welding device welds different positions on the surface of the workpiece.

[0016] 3. Compared with the prior art, the present invention continuously feeds the workpiece out through the feeding channel, which is then clamped by the clamping component and transferred to the rotating component. The bottom of the corresponding welding device drives the workpiece to rotate, thereby allowing multiple angles of the workpiece to correspond to the welding position and improving welding efficiency.

[0023] Please see Figures 1 to 4 This utility model provides a technical solution: a rotary welding fixture for a workstation, including a processing table 1. The top of the processing table 1 is provided with two sets of feeding channels 2. A clamping assembly 3 is provided on the processing table 1 corresponding to the outlet end of the feeding channel 2. The clamping assembly 3 includes a movable slide rail 32, which is fixed to the processing table 1 and parallel to the outlet end of the feeding channel 2. Three sets of electrically powered grippers 31 are slidably mounted on the movable slide rail 32. A rotating assembly 5 is provided on the outer side of the processing table 1 corresponding to the grippers 31. The rotating assembly 5 includes a mounting base 5. 1. The mounting base 51 is fixed on the processing table 1. A rotating platform 52 is rotatably mounted on the top of the mounting base 51. A core-pulling fixture 53 is fixed on the side of the rotating platform 52 facing the gripper 31. The gripper 31 places the unwelded workpiece from the feeding channel 2 into the core-pulling fixture 53. Then, the three-axis cylinder 55 drives the core-pulling movable shaft 57 to move, so that the core-pulling fixture 53 supports the inner diameter of the workpiece, achieving the effect of clamping the workpiece. The servo motor 54 rotates, so that the rotating platform 52 drives the core-pulling fixture 53 to rotate together, thereby driving the product to rotate. At the same time, the laser head performs spiral welding on the product.

[0024] In this embodiment, a cylinder is slidably mounted on the movable slide rail 32, and a gripper 31 is mounted on the extended end of the cylinder. The two sets of feeding channels 2 are inclined, and the outlet end of the feeding channel 2 is located at the lowest point. An electric intercepting gate is provided at the outlet end of the feeding channel 2, which can intermittently feed out workpieces. The gripper 31 approaches the outlet end of the feeding channel 2 under the action of the electrically driven movable slide rail 32 and clamps the fed workpiece. Then, it moves along the movable slide rail 32 to the corresponding position of the rotating component 5, and the cylinder at the rear end pushes the workpiece to be placed on the core-pulling fixture 53 of the rotating component 5.

[0025] In this embodiment, the rotating assembly 5 further includes a servo motor 54. The servo motor 54 is fixedly mounted on the rear end of the rotating platform 52, and the output end of the servo motor 54 is fixedly connected to the rotating platform 52. The rotating platform 52 and the core-pulling fixture 53 have internal central holes, and a core-pulling movable shaft 57 is inserted into the back of the mounting base 51. The core-pulling movable shaft 57 is inserted into the central holes of the rotating platform 52 and the core-pulling fixture 53. A connecting seat 56 is provided on the back of the mounting base 51 at the bottom of the servo motor 54, and the outer end of the core-pulling movable shaft 57 is fixed inside the connecting seat 56. Three-axis cylinders 55 are fixed on both sides of the mounting base 51. The extended end of the three-axis cylinder 55 is fixedly connected to the connecting seat 56. The machining table 1 is equipped with a welding device 4 on the top of the rotating assembly 5. The welding head of the welding device 4 corresponds to the top of the core-pulling fixture 53. After the annular workpiece is fitted onto the core-pulling fixture 53, the three-axis cylinder 55 drives the connecting shaft and the core-pulling movable shaft 57 to move, so that the core-pulling fixture 53 supports the inner diameter of the workpiece, achieving the effect of clamping the workpiece. Then, the servo motor 54 drives the rotating platform 52 to rotate, and the core-pulling fixture 53 and the workpiece rotate synchronously, facing the position of the top welding device 4. The welding device 4 welds different positions on the surface of the workpiece. In this content, the welding device 4 is a common arc welding machine.

[0026] When using the device, an electric intercepting gate is installed at the outlet end of the feeding channel 2, which can intermittently feed out workpieces. The gripper 31 approaches the outlet end of the feeding channel 2 under the action of the electrically driven moving slide rail 32 and clamps the fed workpiece. Then, it moves along the moving slide rail 32 to the corresponding position of the rotating component 5. The cylinder at the rear end pushes the workpiece to be placed on the core-pulling fixture 53 of the rotating component 5. The gripper 31 places the unwelded workpiece of the feeding channel 2 into the core-pulling fixture 53. Then, the three-axis cylinder 55 drives the core-pulling movable shaft 57 to move, so that the core-pulling fixture 53 supports the inner diameter of the workpiece, achieving the effect of clamping the workpiece. The servo motor 54 rotates, so that the rotating platform 52 drives the core-pulling fixture 53 to rotate together, thereby driving the product to rotate. At the same time, the laser head performs spiral welding on the product.
