Description

Technical Field

[0001] The utility model relates to the technical field of H-shaped steel positioning, and particularly relates to a positioning device for H-shaped steel processing. Background Technique

[0002] The H-shaped steel is an economic section high-efficiency profile with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio, and it gets its name because its cross-section is the same as the English letter "H". During the processing of H-shaped steel, cutting is required. When cutting H-shaped steel, in order to ensure the cutting effect, a positioning device is often used to limit and fix it. The positioning device for H-shaped steel cutting is a device designed to ensure that the H-shaped steel can be accurately and stably positioned during the cutting process. In the existing patent application with the application number CN202221438564.X, an automatic cutting and punching device for H-shaped steel is proposed. Although the positioning mechanism set therein can limit the H-shaped steel to be processed and prevent the H-shaped steel from deviating easily during the processing, since its pinch rollers are rotatably installed on the U-shaped blocks and only the pinch rollers are in contact with the H-shaped steel, the positioning mechanism cannot fix the H-shaped steel. As a result, the H-shaped steel is likely to move under the influence of external forces during the cutting process, and finally the H-shaped steel is easily cut and damaged, so it needs to be improved. Content of the Utility Model

[0003] The main purpose of the utility model is to provide a positioning device for H-shaped steel processing, which can effectively solve the problems in the background technique.

Two fixed hydraulic cylinders are symmetrically installed on the upper and lower sides of the outer ends of the connecting brackets. The lower end of the telescopic rod of the upper fixed hydraulic cylinder is fixedly installed with a fixed pressing plate. The fixed pressing plate is composed of a connecting substrate and an anti-slip rubber pad. The anti-slip rubber pad is fixedly installed at the lower end of the connecting substrate. The upper end of the telescopic rod of the lower fixed hydraulic cylinder is fixedly installed with a limiting structure. The limiting structure is composed of a limiting plate and supporting balls. An I-shaped groove is opened at the upper end of the limiting plate, and the I-shaped groove penetrates the limiting plate from front to back. There are several supporting balls, and they are all rotatably installed in the limiting plate.

[0006] Preferably, a limiting through hole is opened on each of the two connecting brackets, and two installation guide rails are symmetrically fixedly installed at the left and right ends of the two connecting brackets.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

Two mounting guide rails 1 are symmetrically fixedly installed on the left and right ends of the two connecting brackets 2. A mobile gantry 6 is installed on the two mounting guide rails 1, and a laser cutting component 7 is installed on the mobile gantry 6.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, two fixed hydraulic cylinders 3 are symmetrically installed at the upper and lower ends of the outer ends of the connecting bracket 2, and a fixed pressure plate 4 is fixedly installed at the lower end of the telescopic rod of the upper fixed hydraulic cylinder 3, and the fixed pressure plate 4 is composed of a connecting base plate 9 and an anti-skid rubber pad 10, and the anti-skid rubber pad 10 is fixedly installed at the lower end of the connecting base plate 9, and a limiting structure 5 is fixedly installed at the upper end of the telescopic rod of the lower fixed hydraulic cylinder 3, and the limiting structure 5 is composed of a limiting plate 11 and a supporting ball 14. An I-shaped groove 12 is opened at the upper end of the limiting plate 11, and the I-shaped groove 12 penetrates the limiting plate 11 front and back at the same time. There are several supporting balls 14 and they are all rotatably installed in the limiting plate 11, and the four fixed hydraulic cylinders 3 are respectively located on the upper and lower sides of the two limiting through-holes 8, and the fixed hydraulic cylinder 3 is fixedly connected to the connecting bracket 2, and the fixed The connecting base plate 9 on the pressure plate 4 is fixedly connected to the telescopic rod of the fixed hydraulic cylinder 3 on the upper side, and a plurality of spherical mounting grooves 13 are provided in the limiting plate 11 on the limiting structure 5, and the plurality of spherical mounting grooves 13 are all connected to the I-shaped groove 12, and a plurality of supporting balls 14 are rotatably installed in the plurality of spherical mounting grooves 13 respectively, and the limiting plate 11 is fixedly connected to the telescopic rod on the fixed hydraulic cylinder 3 on the lower side. By arranging the fixed hydraulic cylinder 3, the fixed pressure plate 4 and the limiting structure 5, they cooperate with each other, which can not only limit the H-shaped steel to prevent the H-shaped steel from running off during the cutting process, but also fix the H-shaped steel, so that the H-shaped steel is not easily moved by external forces when being cut, thereby reducing the probability of the H-shaped steel being damaged during the cutting process.

[0021] It should be noted that the utility model is a positioning device for H-beam processing. When in use, the H-beam to be cut can be passed through the I-shaped groove 12 opened on the limit plate 11. At this time, the support ball 14 will come into contact with the surface of the H-beam, so that the support ball 14 can support the H-beam. At the same time, as the H-beam moves, the H-beam will produce friction with the support ball 14, and the support ball 14 will rotate at this time. When the position of the H-beam to be cut is directly below the laser cutting component 7, the upper fixed hydraulic cylinder 3 is used to cooperate with the fixed pressure plate 4 to fix the H-beam.

Finally, the laser cutting component 7 can be started to cut the H-beam.
