The positioning frame is installed at the output end of the hydraulic cylinder. Multiple positioning grooves are provided at the bottom of the positioning frame. Positioning blocks are provided in each of the multiple positioning grooves. Square grooves and arc-shaped grooves are respectively opened at the top and bottom of the positioning blocks. Through grooves are opened through the multiple positioning grooves. A rotating rod is rotatably installed in the through grooves. The positioning blocks are fixedly installed on the outside of the rotating rods. A drive structure for controlling the rotation of the rotating rods is provided on one side of the positioning frame.

[0006] Furthermore, the drive structure includes an adjusting cylinder, a rack, and a brake gear. A mounting plate is installed on one side of the positioning frame. The adjusting cylinder is installed on the top of the mounting plate. The rack is located at the bottom of the mounting plate and is installed at the output end of the adjusting cylinder. The brake gear is installed at one end of the rotating rod and meshes with the rack on one side.

[0007] Furthermore, the drive structure is a servo motor, and the rotating rod is installed at the output end of the servo motor.

[0008] Furthermore, mounting pads are installed at both ends of the bottom of the mounting bracket.

[0009] Furthermore, the mounting pad has mounting holes.

[0010] The beneficial effects of this utility model are:

[0011] In this invention, the top and bottom of the positioning block are respectively provided with square grooves and arc grooves. The square grooves and arc grooves can be used to conveniently clamp and position workpieces of different shapes, thus making it widely applicable.

[0020] Example 1

[0021] This embodiment proposes the following technical solution: a workpiece welding positioning structure, such as... Figure 1 and Figure 2 As shown, the device includes a mounting frame 1 and a positioning frame 2. The positioning frame 2 is located inside the mounting frame 1. A hydraulic cylinder 3 is mounted on the top of the mounting frame 1, which can push the positioning frame 2 downward. The positioning frame 2 is installed at the output end of the hydraulic cylinder 3. Multiple positioning grooves 4 are provided at the bottom of the positioning frame 2, and positioning blocks 5 are provided in each of the multiple positioning grooves 4. The positioning blocks 5 can be used to clamp and position the workpiece to be welded. The top and bottom of the positioning blocks 5 are respectively provided with square grooves 6 and arc grooves 7. The square grooves 6 and arc grooves 7 can be used to conveniently clamp and position workpieces of different shapes, thus having a wide range of applications. Through grooves are provided in the multiple positioning grooves 4, and rotating rods 8 are rotatably installed in the through grooves. The positioning blocks 5 are fixedly installed on the outside of the rotating rods 8. A drive structure 9 is provided on one side of the positioning frame 2 to control the rotation of the rotating rods 8. The drive structure 9 can drive the rotating rods 8 to rotate, thereby driving the positioning blocks 5 to rotate. Therefore, square grooves 6 or arc grooves 7 can be used to conveniently handle different shapes.

[0022] In its specific implementation, the drive structure 9 includes an adjusting cylinder 901, a rack 902, and a brake gear 903. A mounting plate 10 is installed on one side of the positioning frame 2. The adjusting cylinder 901 is mounted on the top of the mounting plate 10. The rack 902 is located at the bottom of the mounting plate 10 and is mounted on the output end of the adjusting cylinder 901. The brake gear 903 is mounted on one end of the rotating rod 8, and one side of the brake gear 903 meshes with the rack 902. The driving structure 9 allows for adjustment of the position of the positioning block 5. Figure 1 and Figure 2 As shown, when the adjusting cylinder 901 is in the retracted state, the arc groove 7 faces downwards, which can be used for positioning cylindrical workpieces. When positioning a square workpiece is required, the adjusting cylinder 901 is controlled, and the adjusting cylinder 901 can move the rack 902 downwards. Therefore, when the rack 902 moves, it can drive the brake gear 903 to rotate, which in turn can drive the rotating rod 8 and the positioning block 5 to rotate. When the adjusting cylinder 901 is fully extended, the square groove 6 in the positioning block 5 faces downwards, which can be used to position a square workpiece.

[0023] In the specific implementation, mounting pads 11 are installed at both ends of the bottom of the mounting bracket 1. Mounting pads 11 are provided with mounting holes 12, which facilitate the fixing of the mounting bracket 1.

A hydraulic cylinder 3 is mounted on the top of the mounting frame 1, which can push the positioning frame 2 downward. The positioning frame 2 is installed at the output end of the hydraulic cylinder 3. Multiple positioning grooves 4 are provided at the bottom of the positioning frame 2, and positioning blocks 5 are provided in each of the multiple positioning grooves 4. The positioning blocks 5 can be used to clamp and position the workpiece to be welded. The top and bottom of the positioning blocks 5 are respectively provided with square grooves 6 and arc grooves 7. The square grooves 6 and arc grooves 7 can be used to conveniently clamp and position workpieces of different shapes, thus having a wide range of applications. Through grooves are provided in the multiple positioning grooves 4, and rotating rods 8 are rotatably installed in the through grooves. The positioning blocks 5 are fixedly installed on the outside of the rotating rods 8. A drive structure 9 is provided on one side of the positioning frame 2 to control the rotation of the rotating rods 8. The drive structure 9 can drive the rotating rods 8 to rotate, thereby driving the positioning blocks 5 to rotate. Therefore, square grooves 6 or arc grooves 7 can be used to conveniently handle different shapes.

[0026] In the specific implementation, the drive structure 9 is a servo motor 911, and the rotating rod 8 is installed at the output end of the servo motor 911. The position of the positioning block 5 can be adjusted through the drive structure 9, such as... Figure 3 and Figure 4 As shown, in the initial state, the circular slot of the servo motor 911 faces downwards, which can be used for positioning cylindrical workpieces. When positioning a square workpiece is required, the servo motor 911 is controlled to drive the rotating rod 8 to rotate, and the rotating rod 8 drives the positioning block 5 to rotate. Then the square slot 6 faces downwards, which can be used to position the square workpiece.

[0027] In the specific implementation, mounting pads 11 are installed at both ends of the bottom of the mounting bracket 1. Mounting pads 11 are provided with mounting holes 12, which facilitate the fixing of the mounting bracket 1.
