[0023] Combined with Figures 1-8 , this embodiment discloses a laser marking tooling, including a limiting working platform 1, and the limiting working platform 1 is used for placing H-shaped profiles.

[0024] The overall contour of the limiting working platform 1 is a cuboid, including a bottom plate 11, side walls 12, and a rear wall 13. The side walls 12 are respectively located on the left and right sides of the bottom plate 11, and the rear wall 13 is located at the rear side of the bottom plate 11, all protruding from the edge of the bottom plate 11. The front end of the limiting working platform 1 is of an open structure, facilitating the feeding of profiles from the front end to the bottom plate 11, and the rear wall 13 also plays a limiting role to prevent the profiles from shifting forward and backward.

[0025] On the bottom plate 11, there are also several card slots 14. The direction of the card slots 14 is from front to back, and the positions of the card slots 14 are symmetrical about the center line of the bottom plate 11. When it is necessary to mark the H-shaped steel, it is sent along the card slots 14 from front to back to the limiting working platform 1. Through the transitional fit between the card slots 14 and the H-shaped steel and the resistance of the rear wall 13, the fixation of the H-shaped steel is ensured without displacement or falling off. In this way, there is no need to hold the marking part by hand during the marking process, reducing the manpower requirement. In addition to placing the H-shaped steel in the card slots 14, the profile can also be placed inside the two side walls 12, and the profile is fixed by the side walls 12. In this way, when the limiting working platform 1 is provided with N (N≥1) card slots 14, the fixation of at least N / 2 + 1 H-shaped steels can be realized. In this embodiment, N = 4, that is, 2 pairs of card slots 14 are provided on the bottom plate 11, and the positions of the H-shaped steels of the XL / XM / LI products can be accurately positioned. Among them, the H-shaped steel of the XL-sized product is located inside the two side walls 12, the two ends of the H-shaped steel of the XM-sized product are located in the card slots 14 near the side, and the H-shaped steel of the LI-sized product is located in the card slots 14 near the center of the bottom plate 11.

[0026] Preferably in this embodiment, a protection slot 15 running through the limiting working platform 1 in the front-back direction is provided in the center of the limiting working platform 1. The protection slot 15 divides a part of the bottom plate 11 and the rear wall 13 respectively, forming a slot with an "L"-shaped cross-section. The bottom surface of the protection slot 15 is lower than the upper surface of the bottom plate 11. When performing laser marking, a protection pad is attached to the lower surface of the workpiece. The protection slot 15 provides a placement space for the protection pad, and the rear wall 13 is a break at the protection slot 15, which is convenient for placing the protection pad.

[0027] The limiting working platform 1 is fixed on the tooling platform 2. In this embodiment, the tooling platform 2 is integrally in a sheet-like rectangle, and the limiting working platform 1 can rotate with the rotation of the tooling platform 2.

[0028] Below the tooling platform 2, there are columns 3 and a rotation mechanism for supporting and rotating the tooling platform 2. The column 3 is integrally cylindrical, and its top is connected to the tooling platform 2 to support the tooling platform 2. The upper end inside it is a hollow structure. The rotation mechanism includes a rotating column 4, a bearing 5, and a limiting member 6; the rotating column 4 and the bearing 5 are arranged inside the upper end of the column 3, the bearing 5 is sleeved on the rotating column 4, the outer side of the bearing 5 is connected to the inner side of the column 3, the upper end of the rotating column 4 is connected to the tooling platform 2, and the limiting member 6 is in a columnar structure, with one end connected to the rotating column 4 and the other end horizontally extending outwards. Through the bearing 5, the sliding of the rotation mechanism can be made convenient and easy. In this embodiment, the column 3, the rotating column 4, and the limiting member 6 are all integrally cylindrical, and in actual use, a suitable shape that meets the requirements can be selected according to needs.

[0029] A notch 31 is provided on the outer surface of the vertical column 3. The height of the notch 31 is the same as that of the limiting member 6, and the limiting member 6 is arranged in the notch 31. In this embodiment, the notch 31 is arranged parallel to the ground. Correspondingly, the limiting member 6 is also arranged parallel to the ground. The connecting lines between the two ends of the notch 31 and the center line of the rotating column 4 form an included angle, and the range of the included angle is 0 to 90°. The distance between the notch 31 and the top end of the vertical column 3 is 100 mm. In actual use, an appropriate angle range can be selected according to the marking requirements of the workpiece, as long as the design of the notch 31 does not affect the strength of the vertical column 3. At the same time, in order to install the rotating mechanism, a notch that is vertically upward and communicates with the top end of the vertical column 3 is provided at one end of the notch 31 of the vertical column 3, which is convenient for the rotating mechanism to be placed into the vertical column 3 from top to bottom.

[0030] Preferably, in this embodiment, a fastener 7 is also sleeved outside the limiting member 6. The fastener 7 is used to fasten the limiting member 6 on the vertical column 3. The fastener 7 is a hollow structure with a thread in the middle. The hollow structure is adapted to the outer dimensions of the limiting member 6, and threads are also provided on the outer side of the limiting member 6. The two can be connected by threads. When the fastener 7 is tightened against the outer side of the vertical column 3, the limiting member 6 can be fixed in position. In this embodiment, the fastener 7 is a columnar structure, and threads are provided on the side of the limiting member 6 and the fastener 7 close to the vertical column 3. In actual use, the shape of the fastener 7 is not limited, as long as it can be firmly combined with the limiting member 6.

[0031] Preferably, in this embodiment, a lower flat plate 8 is further connected to the bottom end of the vertical column 3. The lower flat plate 8 is a flat plate structure and is arranged on the ground, which is convenient for the laser marking tooling to be placed stably on the ground.

[0032] With the laser marking tooling of this application, when marking an H-shaped profile, the H-shaped profile is placed in the corresponding specification card slot 14 on the limiting working platform 1, and then pushed backward until it abuts against the rear wall 13, thereby fixing the marking part. By rotating the rotating part at the notch 31, the tooling platform 2 and the limiting working platform 1 are rotated by a certain angle, so that the marking part is rotated to a suitable position. Then, the fastener 7 is tightened until the fastener 7 is close to the vertical column 3, thereby fixing the limiting member 6, and further fixing the marking part. Thus, the precise positioning of the marking part is realized, and there is no need for workers to hold it by hand for operation, reducing waste of manpower.

[0033] The laser marking tooling of this embodiment realizes the precise positioning of marking workpieces of different sizes through the limiting working platform 1, adjusts the angular position of the tooling platform 2 through the rotation of the rotating mechanism, adjusts the stroke through the threaded cooperation between the fastener 7 and the limiting member 6 on the rotating mechanism, and fixes the position of the rotating mechanism through friction. The operation is simple and convenient, thus ensuring the marking accuracy rate, reducing waste of labor, improving the marking efficiency, and having an easy-to-fabricate structure and high stability. Therefore, it has good application prospects.
