Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to a kind of steel bridge plate unit magnetic line marking equipment, which can be independently adsorbed on the surface of plate unit, without needing to hold line marking tool closely to plate unit during line marking process, and can ensure line marking accuracy. BACKGROUND
[0002] In the process of manufacturing bridge steel structure, the bridge steel structure is generally divided into several plate units for easy manufacturing, and then welded into bridge steel structure. During the manufacturing process of plate unit, the two surfaces of steel plate need to be marked. The current method is to hold a right-angle ruler or U-shaped tool to adjust the position while marking, which requires two people to cooperate. During the marking process, the person holds the right-angle ruler and U-shaped tool to adjust the position, which is prone to errors, resulting in poor line marking accuracy, affecting workpiece quality and production cycle. SUMMARY
[0003] Design purpose: to avoid the shortcomings in the background art, a kind of steel bridge plate unit magnetic line marking equipment is designed, which can independently adsorb the line marking tool on the surface of plate unit, does not need to hold the line marking tool closely to plate unit during line marking process, can prompt whether the adjustment equipment is level through the bubble level, ensures the line marking accuracy, improves the production efficiency and is easy to operate, and has high stability.
[0004] Design scheme: in order to achieve the above design purpose, the steel bridge plate unit magnetic line marking equipment of the utility model is mainly composed of L-shaped main ruler, movable vice ruler, moving block, fastening bolt, bubble level and internal magnet strip. The movable vice ruler can move to the appropriate scale position along the L-shaped main ruler as needed, and the strip-shaped magnet strip built-in the L-shaped main ruler can be independently adsorbed on the plate unit, so that the L-shaped main ruler does not need to be manually positioned, and the line marking can be completed by one person.
[0005] When in use, the thickness of the plate unit steel plate to be marked is observed, the fastening screw on the movable vice ruler is loosened, the vice ruler is moved to the appropriate scale position on the right side, the U-shaped line marking equipment composed of the main ruler and the vice ruler of the magnetic line marking equipment is pushed into the plate unit steel plate to be marked, the magnetic line marking equipment can be independently adsorbed on the plate unit, the device is adjusted to be level through the bubble level on the vice ruler, then the main ruler and the vice ruler are adjusted to be aligned with the sample hole, after adjustment, the fastening screw on the vice ruler is tightened, and the line marking starts.
[0006] Technical scheme: a kind of steel bridge plate unit magnetic line marking equipment, the end face of L-shaped main ruler is provided with bubble level, and there is magnet strip in the ruler body of L-shaped main ruler. The movable vice ruler moves along the L-shaped main ruler through the moving block, and the moving block is clamped on the L-shaped main ruler.
[0007] Compared with the background art, the utility model has the advantages that: 1. The equipment is automatically adsorbed on the surface of the plate unit, and it is not necessary to hold the equipment for adjustment all the time, so that the hands are freed, the labor intensity is reduced, and the production efficiency is improved; 2. The manual operation error is reduced through the magnet adsorption fixing and the bubble adjustment mode, and the line drawing precision is effectively improved; 3. The equipment is adjustable, suitable for various plate thicknesses, simple and quick to operate, and high in applicability. BRIEF DESCRIPTION OF DRAWINGS
[0008] Figure 1 is a schematic view of a steel bridge plate unit magnet adsorption type line drawing equipment.
[0009] Figure 2 is a schematic view of an equipment working process. DETAILED DESCRIPTION
[0010] Embodiment 1: refer to the attached Figure 1 and 2 A steel bridge plate unit magnet adsorption type line drawing equipment, the end face of the L-shaped main ruler 1 is provided with a bubble 5, the L-shaped main ruler 1 has a magnet adsorption strip 6 in the ruler body, the movable vice ruler 2 moves along the L-shaped main ruler 1 through the moving block 3, and the moving block 3 is clamped on the L-shaped main ruler 1. The upper end face of the moving block 3 is provided with a fastening screw 4, so as to facilitate the movement or positioning of the moving block 3 on the L-shaped main ruler 1. The L-shaped main ruler 1, the bubble 5, the magnet adsorption strip 6 in the L-shaped main ruler 1 and the movable vice ruler 2 and the moving block 3 are connected and the manufacturing process and the assembly process are all prior art, which will not be described here.
[0011] The equipment working process is as follows: ① On the line drawing platform, the reference position on the surface of the plate unit steel plate is measured, and a sample punching hole is punched. ② The U-shaped main ruler and vice ruler of the magnet adsorption type line drawing equipment with adjusted scales are pushed into the plate unit, the equipment is adjusted to be horizontal, the reference position to be drawn is aligned, the fastening screw is tightened, and the line is drawn by using a line needle. ③ The magnet adsorption type line drawing equipment is used to repeat the above step, and the line is drawn on the other side of the sample punching hole of the plate unit.
[0012] It should be understood that: although the above embodiment has a more detailed word description of the design idea of the utility model, these word descriptions are only simple word descriptions of the design idea of the utility model, but not the limitation of the design idea of the utility model, and any combination, addition or modification which does not exceed the design idea of the utility model falls within the protection scope of the utility model.
