[0002] A fixture structure based on visual recognition refers to a fixture structure that uses computer vision technology to achieve fixture positioning and clamping. It obtains images or video streams of workpieces through visual sensors such as cameras, and processes and analyzes them through computer vision algorithms, thereby identifying information such as the position and posture of the workpiece, and then controlling the fixture to position and clamp. In the prior art, there is a fixture based on visual recognition, and its technical solution includes an operating box, a fixed box is fixedly installed on the top of the operating box, a support box is fixedly installed on the top of the fixed box, a clamping assembly is provided inside the operating box, a hydraulic cylinder is fixedly installed inside the fixed box, the hydraulic rod of the hydraulic cylinder passes through the operating box and is fixedly connected to the conical block provided inside the operating box, and a screw is rotatably connected inside the support box. The utility model has the advantages of being easy to quickly clamp and fix the workpiece, greatly improving work efficiency, improving work progress, and being more convenient to use.

When the cylinder 9 is started, the telescopic end of the cylinder 9 is extended and retracted, so that the sliding block 10 fixedly mounted on the telescopic end of the cylinder 9 moves in the shell 1.

[0035] Among them, the clamp assembly also includes a round rod 15 fixedly installed in the shell 1, the bottom of the shell 1 is opened, and two groups of sliding plates 14 are slidably installed on the round rod 15. A connecting rod 12 is fixedly installed on one side of the sliding plate 14, and a C-shaped plate is fixedly installed on the top of the connecting rod 12. Rollers 11 are rotatably installed in the C-shaped plates. The rollers 11 roll on the inclined surfaces on both sides of the sliding block 10, thereby changing the lateral position of the rollers 11, so that the two groups of connecting rods 12 move toward each other.

[0036] In addition, both sides of the sliding block 10 are inclined, and the rollers 11 are respectively closely attached to the inclined surfaces on both sides of the sliding block 10, and a spring 16 is fixedly connected between the side of the sliding plate 14 away from the sliding block 10 and the inner wall of the housing 1. When the sliding plate 14 slides on the round rod 15, the sliding plate 14 compresses the spring 16, and when the sliding block 10 moves upward, the spring 16 resets and applies force to the sliding plate 14, so that the rollers 11 are always in close contact with the inclined surfaces on both sides of the sliding block 10.

[0037] Finally, a swing rod 7 is fixedly installed at the bottom of the connecting rod 12, and the two groups of swing rods 7 are symmetrically arranged. A fixed shaft 13 is provided at the center position of the two groups of swing rods 7. The swing rods 7 are rotatably installed on the fixed shaft 13, and a clamping plate 8 is fixedly installed on the side of the bottom of the swing rod 7 away from the shell 1.

A handle 38 for controlling the rotation of the bidirectional screw rod 33 is provided on the outer wall of one side of the mounting box 31. A disc is fixedly installed on one end of the bidirectional screw rod 33 passing through the mounting box 31, and the handle is fixedly installed on the disc. Two sets of moving plates 34 are threadedly connected to the bidirectional screw rod 33, and a mounting column 39 is fixedly installed on one side of the moving plate 34 near the fixing bolt 32. The handle 38 is turned to rotate the bidirectional screw rod 33, so that the moving plate 34 threadedly connected to the bidirectional screw rod 33 moves toward each other.

[0039] Among them, two groups of rectangular plates 35 are fixedly installed in the installation box 31, and circular holes 36 are opened on the rectangular plates 35 for the installation columns 39 to pass through. The rectangular plates 35 are respectively located on the side of the movable plate 34 close to the fixing bolts 32, and two groups of rectangular holes 37 are opened on the side of the installation box 31 close to the installation box 17.
