[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a welding fixture for a frame-type workpiece provided by this utility model; Figure 2 for Figure 1 The diagram shows the structure of the mobile frame. Figure 3 for Figure 2 The enlarged schematic diagram of part A shown below; Figure 4 for Figure 1 The enlarged schematic diagram of part B is shown. A welding fixture for a frame-like workpiece includes: a support frame 1, a rotating device 2, a rotating frame 3, a moving device 4, a moving frame 5, a limiting frame 6, and a limiting device 7; The rotating device 2 is located on the top of the support frame 1, and the rotating frame 3 is fixedly located at the output end of the rotating device 2; The moving device 4 includes a moving groove 41, two moving blocks 42 and a fixing device 43. The moving groove 41 is opened inside the rotating frame 3. The two moving blocks 42 are slidably connected inside the moving groove 41. The fixing device 43 is disposed on one side of the moving block 42. The movable frame 5 is fixedly installed on the top of the movable block 42, the limiting frame 6 is installed on the top of the movable frame 5, and the limiting device 7 is installed on the surface of the limiting frame 6.

[0019] The rotating device 2 is a servo motor, which is fixedly installed on one side of the support frame 1 and its output end is fixedly installed on one side of the rotating frame 3. The rotating frame 3 is rotatably connected to the inside of the support frame 1 and is used to drive the rotating frame 3 to rotate after starting, so as to adjust the angle of the rotating frame 3.

[0020] The rotating frame 3 is equipped with two sets of moving devices 4, and the bottoms of the two moving frames 5 are respectively fixedly connected to the tops of the four moving blocks 42.

[0021] Both movable frames 5 are equipped with movable devices 4 inside. The tops of the four movable blocks 42 in the two sets of movable devices 4 are respectively fixedly installed with four limiting frames 6 for supporting frame-type workpieces.

[0022] The fixing device 43 includes a fixing pin 431, a fixing block 432 and multiple fixing grooves 433. The fixing pin 431 is threaded to the inside of the movable block 42. One end of the fixing block 432 is rotatably connected to one end of the fixing pin 431. The multiple fixing grooves 433 are all opened inside the movable frame 5.

[0023] The fixing pin 431 is a bolt, which is threaded into the inside of the moving block 42. After the moving block 42 is moved to the appropriate position, the bolt is rotated to one side, so that the bolt moves downward inside the moving block 42, thereby pushing the fixing block 432 into the inside of the fixing groove 433 and limiting the movement of the moving block 42.

[0024] The limiting device 7 includes a telescopic rod 71, a limiting pin 72, and a limiting member 73. The telescopic rod 71 is located at the top of the limiting frame 6, the limiting pin 72 is located inside the telescopic rod 71, and the limiting member 73 is located at the bottom of the telescopic rod 71.

[0025] The telescopic rod 71 is a double-ended telescopic rod, and the limiting pin 72 is a bolt. The inner rod of the telescopic rod 71 has multiple threaded holes that are compatible with the bolt. After the telescopic rod is extended to a suitable position, the bolt is installed into the threaded hole to limit the length of the telescopic rod.

[0026] The limiting component 73 includes a limiting rod 731 and a limiting plate 732. The limiting rod 731 is threadedly connected to the inside of the telescopic rod 71, and one end of the limiting plate 732 is rotatably connected to one end of the limiting rod 731.

The limiting rod 731 is threadedly connected to the inside of the mounting plate, and one end is fixedly connected to a rotating handle. When the limiting rod 731 is rotated to one side, it pushes the limiting plate 732 to one side, thereby facilitating the clamping and limiting of frame-type workpieces of different thicknesses.

[0028] The top of the limiting plate 732 contacts the bottom surface of the telescopic rod 71 to limit the position of the limiting plate 732.

[0029] The limiting plate 732 has multiple rotating grooves 8 inside, and rotating rollers 9 are rotatably connected inside each of the multiple rotating grooves 8.

[0030] The rotating roller 9 is used to reduce the friction between the limiting plate 732 and the frame-like workpiece, thereby facilitating the downward movement of the limiting plate 732 to the appropriate position.

[0031] A protective sleeve 10 is fixedly connected to the surface of the rotating roller 9. The protective sleeve 10 is used to protect the rotating roller 9 and the frame-like workpiece.

[0032] The protective sleeve 10 is used to protect the rotating roller 9 and the frame-like workpiece, preventing damage to the surface of the frame-like workpiece when the rotating roller 9 moves downward on the surface of the frame-like workpiece.

[0033] The working principle of the welding fixture for frame-type workpieces provided by this utility model is as follows: In use, after loosening the fixing device 43, the moving frame 5 is moved to one side, thereby causing the moving block 42 to move to one side inside the moving groove 41. After the moving block 42 moves to the appropriate position, the fixing device 43 can be installed.

[0034] By repeating the above steps, the limit frame 6 can be adjusted to one side to a suitable position.

[0035] Compared with related technologies, the welding fixture for frame-type workpieces provided by this utility model has the following beneficial effects: This utility model provides a welding fixture for frame-type workpieces. The distance between the two moving frames 5 and the distance between the four limiting frames 6 can be adjusted by the moving device 4, so that the two moving frames 5 and the four limiting frames 6 can be adjusted to a suitable position according to the size of the frame-type workpiece to be processed, which facilitates the limiting of workpieces of different sizes and improves applicability.
