[0022] The embodiments of the present invention are described in further detail below with reference to the accompanying drawings and examples.

[0023] Example 1:

[0024] As attached Figure 1 To the attached Figure 5 As shown:

[0025] The utility model provides a plate positioning device for a laser cutting machine, comprising: a base 1; the base 1 adopts a rectangular groove structure, and a through-type rectangular through-groove structure is provided on the front side of the base 1, and a through-type rectangular through-groove structure is provided on the left and right sides of the base 1, and a through-type circular through-groove is provided on one side of the bottom of the base 1, and a group of U-shaped groove structures are provided on all four sides of the top of the base 1; a cylinder 107 is fixedly arranged in the U-shaped through-groove on the top of the base 1; a splint 108 with an L-shaped plate structure is provided at the inner end of the cylinder 107 for transmission connection, and a group of through-type circular through-groove structures are provided on both sides of the bottom of the splint 108, and a through-type circular through-groove structure is provided on both sides of the top of the splint 108; a group of second slide rods 113 with a cylindrical structure are slidably provided in the circular through-groove on both sides of the top of the splint 108.

[0026] Among them, a double gear 109 is rotatably set on the rear side of the splint 108; a group of first sliding rods 110 are slidably set in the circular through grooves on both sides of the splint 108, and a spring is sleeved on the outer side of the first sliding rod 110; a connecting plate 111 with a rectangular plate structure is fixedly set on the front side of the two groups of first sliding rods 110; a first rack 112 is fixedly set on the rear side of the first sliding rod 110, and the first rack 112 is meshed and connected with the double gear 109; a second rack 114 is fixedly set on the top rear side of the two groups of second sliding rods 113, and the second rack 114 is meshed and connected with the double gear 109.

[0027] The specific usage and function of this embodiment are as follows:

[0028] During processing, the plate is placed in the middle of the top of the top plate 105, and then the four groups of cylinders 107 are started synchronously to drive the groups of clamping plates 108 to move inward, so that the plate is fixed and clamped synchronously in four directions. In the process of the clamping plates 108 moving inward, the groups of connecting plates 111 will first be in contact with the plate. After the connecting plates 111 come into contact with the plate, they drive the first slide bar 110 to slide outward along the circular through groove of the clamping plate 108. In this process, the first rack 112 is synchronously driven to slide outward, and the double gear 109 is driven to rotate through the first rack 112. The double gear 109 drives the second rack 114 to move downward, thereby synchronously driving the two groups of second slide bars 113 along the clamping plate The circular groove at the top of the plate 108 slides downward, and as the clamping plate 108 continues to approach the plate, the bottom ends of the two groups of second sliding bars 113 also continue to approach the top of the plate. When the bottom ends of the second sliding bars 113 are pressed against the top of the plate, the connecting plate 111 and the first sliding bar 110 can no longer slide backward. At this time, through the cooperation of the connecting plate 111 and the two groups of second sliding bars 113, the plate can be fixed and clamped from one side and the top at the same time. Through the cooperation of the four groups of connecting plates 111 and the groups of second sliding bars 113, the fixed position of the plate can be completed from four directions, which greatly improves the limiting effect of the plate and improves the stability of the plate during processing.
