Description

Technical Field

[0001] The utility model relates to the technical field of metal structure manufacturing, in particular to a grinding device for metal structure manufacturing. Background Technique

[0002] Metal structure manufacturing refers to the production activities of manufacturing metal components, metal component parts, steel products for construction and the like with metals such as iron, steel or aluminum as the main materials. After the metal structure is formed, burrs often remain on the outer surface, which requires grinding. It is a polishing method that removes the convex parts after polishing by cutting and plastic deformation of the material surface to obtain a smooth surface. Generally, oilstone bars, wool wheels, sandpapers, etc. are used, mainly by manual operation. For special parts such as the surface of a rotating body, auxiliary tools such as a turntable can be used. For those with high surface quality requirements, the ultra-precision lapping and polishing method can be adopted. The ultra-precision lapping and polishing is to use a special grinding tool, in the lapping and polishing liquid containing abrasive, tightly press on the machined surface of the workpiece and make a high-speed rotary motion.

[0003] At present, for the grinding device for metal structure manufacturing, most are that workers hold a grinding machine by hand, or hold a metal workpiece for polishing and grinding. The efficiency is low, and there is a certain danger. During the grinding process, debris is easily generated, affecting the working environment. The grinding head cannot be flexibly adjusted and replaced, and the detailed grinding is not in place. When grinding a metal workpiece, the position is likely to shift, resulting in low working efficiency and low working quality. Therefore, we propose a grinding device for metal structure manufacturing. Content of the Utility Model

It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model, and are not intended to limit the present utility model.

[0023] Embodiment: As Figures 1-4 shown, a grinding device for manufacturing a metal structure of the present utility model includes a box body 1. It is characterized in that a fixing plate 2 is fixedly connected to the top of the box body 1, a fixed box 3 is fixedly installed at the upper end of the fixing plate 2, a first comb teeth 4 is movably connected inside the fixed box 3, several steel balls 5 are arranged inside the fixed box 3, a chute 6 is opened on the surface of the fixing plate 2, a sliding box 7 is slidably connected inside the chute 6, a second comb teeth 401 is slidably connected inside the sliding box 7, a ball screw 8 is arranged inside the chute 6 through a bearing, and the outer circumference of the ball screw 8 is threadedly connected to the bottom of the sliding box 7, and one end of the ball screw 8 is fixedly connected to a handle 9.

[0024] Among them, a vacuum cleaner 11 is fixedly installed inside the box body 1 through a limit plate 10, and dust inlets 12 are symmetrically fixedly connected to the upper end of the vacuum cleaner 11. By setting the vacuum cleaner 11, the debris and dust generated during grinding can be collected, reducing the generation of dust and debris.

[0025] Among them, a telescopic hose 13 is fixedly installed inside the dust inlet 12, and the telescopic hose 13 passes through the top of the box body 1 and is fixedly connected to a dust suction port 14. By setting the telescopic hose 13, the length can be changed by telescoping, expanding the scope of use.

[0026] Among them, support frames 15 are symmetrically fixedly installed on both sides of the fixing plate 2, and the support frames 15 are detachably connected to the dust suction port 14. By setting the support frames 15, the dust suction port 14 can be used as a support.

[0027] Among them, the lower end of the vacuum cleaner 11 is fixedly connected with a discharge port 16, and a material receiving box 17 is arranged on one side of the discharge port 16. By arranging the material receiving box 17, the debris generated during the grinding process of the metal workpiece can be collected uniformly.

[0028] Among them, the top of the box body 1 is symmetrically and fixedly connected with support plates 18. A sliding rod 19 is slidably connected inside the support plates 18 through a slide rail. By arranging the sliding rod 19, the grinding tool can be driven to move horizontally to adjust the position.

[0029] Among them, a telescopic frame 20 is fixedly installed on the surface of the sliding rod 19. A driving motor 21 is fixedly installed at the lower end of the telescopic frame 20.

[0030] Working principle: During use, place the metal workpiece to be ground on the fixed plate 2. By rotating the handle 9, drive the ball screw 8 to rotate, drive the sliding box 7 to move towards the metal workpiece until the second comb teeth 401 and the first comb teeth 4 clamp the metal workpiece. When the first comb teeth 4 and the second comb teeth 401 are squeezed by the metal workpiece, they will push the steel balls 5 in the internal spaces of the fixed box 3 and the sliding box 7 to flow until the steel balls 5 cannot flow, profiling the contour of the metal workpiece, and then the metal workpiece can be clamped. Since the friction between the first comb teeth 4, the second comb teeth 401 and the steel balls 5 is relatively large, it is not easy to slide and loosen during use, ensuring the stability and accuracy of the processing process. Through the first comb teeth 4 and the second comb teeth 401, the first comb teeth 4 and the second comb teeth 401 can be automatically adjusted according to metal workpieces of different sizes and shapes, expanding the specification range of the metal workpiece. By adjusting the position of the sliding rod 19, start the telescopic frame 20, drive the grinding head 23 to move towards the metal workpiece, start the driving motor 21, grind the metal workpiece, start the vacuum cleaner 11, and through the suction port 14, the debris, fines and dust can be centrally collected and processed through the telescopic hose 13, reducing the pollution of the working environment. Collect through the material receiving box 17 and uniformly process the collected metal debris, thereby improving the working efficiency of the cleaning work, avoiding the accumulation of metal debris on the fixed plate 2, and when the vacuum cleaner 11 is in use, accelerating the air flow rate on the fixed plate 2, and can reduce the temperature of the metal workpiece during grinding when grinding.
