Description

TECHNICAL FIELD

[0001] The utility model relates to angle steel welding technical field especially angle steel fixing device. BACKGROUND

[0002] Angle steel is commonly known as angle iron, which is a long strip steel material with two perpendicular sides forming an angle. It is divided into equilateral angle steel and unequal angle steel. The two sides of equilateral angle steel are equal in width. Angle steel can be used to form various load-bearing components according to different structural needs, or as connecting pieces between components. An angle steel tripod formed by welding two angle steels is widely used in various building structures and engineering structures. When constructing a core tube of a high-rise building, the vertical angle steel support structure needs to withstand huge vertical gravity and horizontal wind load, earthquake force, etc. Vertical and stable connection of angle steel can be achieved through vertical welding, ensuring the stability and strength of the key structure such as the core tube.

[0003] The utility model discloses a kind of angle steel tripod welding fixed devices of announcement number CN220679855U China utility model, including operation table and two clamping blocks being set in the top of operation table: the top of the operation table is welded with two fixed frame one, the top of the operation table is welded with fixed frame two, two clamping blocks are penetrated with threaded rod one on the side away from fixed frame two, the threaded rod one is connected with clamping block by screw thread, two threaded rods one are penetrated to the inner cavity of fixed frame two. The utility model discloses two angle steels are placed on the top of operation table, and make the welding place of two angle steels be located in the inner cavity of welding port, start motor one and two motor two drive two pressing plates and two fixed blocks to be fixed to angle steel, prevent angle steel from deviating when welding, increase the stability when angle steel is welded, i.e. it can be achieved that angle steel is fixed by fixed mechanism, avoid deviation when user welds angle steel, increase the stability when welding.

[0004] The existing fixed device can only limit the angle steel in the horizontal direction. When facing the vertical angle steel, it cannot provide effective fixation, which means that when welding the vertical angle steel, the operator cannot ensure the stability of the position of the angle steel during the welding process, which can easily cause the angle steel to deviate. This deviation not only affects the precision of welding, but also makes it difficult to meet the standard requirements of weld quality, increasing the rate of defective products. Therefore, there is a problem that it is not convenient to limit the angle steel in the vertical direction. UTILITY MODEL CONTENTS

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0030] Example 1

[0031] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the first embodiment of the present invention. This embodiment provides a fixing device for angle steel, including an angle steel body 1. A limiting mechanism 2 is slidably connected to the outer surface of the angle steel body 1. A positioning mechanism 3 is rotatably connected to the outer surface of the limiting mechanism 2. The positioning mechanism 3 includes a rotating disk 305 rotatably connected to the upper surface of a moving plate 207. A connecting rod 304 is hinged to the outer surface of the rotating disk 305. A moving block 302 is hinged to the other end of the connecting rod 304. A limiting block 301 is fixedly connected to the outer surface of the moving block 302. The lower surface of the limiting block 301 is in contact with the outer surface of the angle steel body 1.

[0032] The specific positioning mechanism 3 also includes a limiting groove 303 opened on the upper surface of the movable plate 207. The inner side of the limiting groove 303 is slidably connected to the outer surface of the movable block 302, and the limiting groove 303 adopts a convex structure. The lower surface of the limiting block 301 adopts an inverted stepped structure. The upper surface of the rotating disk 305 is fixedly connected to the rotating block 307. The lower surface of the rotating disk 305 is fixedly connected to the limiting ring 310. The outer surface of the limiting ring 310 is rotatably connected to the interior of the movable plate 207. The outer surface of the rotating disk 305 is provided with a through hole 308. The inner side of the rotating disk 305 is rotatably connected to the clamping block 309. The outer surface of the clamping block 309 is fixedly connected to the bolt 306. The outer surface of the bolt 306 is threadedly connected to the upper surface of the movable plate 207.

[0033] Furthermore, through the linkage structure of the rotating disk 305, connecting rod 304 and moving block 302, the positioning and clamping of angle steel can be quickly realized. The operation is simple and convenient, and it can adapt to angle steel of different thicknesses. The inverted stepped structure design of the limiting block 301 ensures that it can fit tightly when clamping angle steel of different thicknesses, ensuring the accuracy and stability of positioning, and effectively improving the work efficiency of angle steel processing or assembly.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The limiting mechanism 2 includes a movable plate 207 that is slidably connected to the lower surface of the angle steel body 1. A limiting frame 202 is fixedly connected to the upper surface of the movable plate 207. A roller 204 is rotatably connected to the outer surface of the limiting frame 202.

[0036] The lower surface of the specific movable plate 207 is fixedly connected to multiple sets of universal wheels 201, and the outer surface of the limiting frame 202 is fixedly connected to a fixed frame 208. The outer surface of the fixed frame 208 is in contact with the right angle side of the angle steel body 1. The upper surface of the fixed frame 208 is fixedly connected to a fixed outer shell 203. The inner wall of the fixed outer shell 203 is slidably connected to a telescopic rod 206. The outer surface of the telescopic rod 206 is rotatably connected to a roller 205. The outer surface of the roller 205 is slidably connected to the outer surface of the angle steel body 1. The inner wall of the fixed outer shell 203 is fixedly connected to a spring 209. The other end of the spring 209 is fixedly connected to the outer surface of the telescopic rod 206.

[0037] When another set of vertical angle steel is added, the roller inside the fixed housing slides into contact with the outer surface of the angle steel to reduce friction and limit movement. The spring adapts to the size of the angle steel and extends and retracts accordingly, pushing the telescopic rod to keep the roller in close contact with the angle steel, thus firmly clamping the upper angle steel between the two sets of welded angle steel.

[0038] Working Principle: First, utilizing the convenient mobility of the casters 201, the fixing device is easily moved to the work area. The casters 201 can flexibly turn, allowing them to move freely in different terrains and narrow spaces, quickly reaching the required position. Once in the designated position, the angle steel body 1 to be welded or assembled is placed on the upper surface of the moving plate 207. The fixing bracket 208 fits tightly against the right-angle side of the angle steel body 1, initially restricting the position of the angle steel and ensuring its stable placement. During placement, the outer surfaces of the two sets of angle steel bodies 1 to be welded should be kept as close as possible. Next, the angle steel is positioned and clamped by rotating the rotating block 3. 07. The rotating disk 305 rotates synchronously. The rotation of the rotating disk 305 causes the connecting rod 304, which is hinged to it, to shift. The other end of the connecting rod 304 then causes the moving block 302 to slide within the limiting groove 303. Since the limiting groove 303 adopts a convex structure, it can effectively prevent the moving block 302 from coming out during the sliding process, ensuring the stability of its movement trajectory. The movement of the moving block 302 causes the limiting block 301 to gradually approach the angle steel body 1 until the outer surface of the limiting block 301 is tightly fitted with the angle steel body 1, realizing the initial clamping and fixing of the angle steel, ensuring that the angle steel will not shift during processing. Then, the bolt 306 is rotated. The bolt 306 is threadedly connected to the upper surface of the moving plate 207. When the bolt 306 is rotated, the bolt 306 causes the clamping block 309 to move downward. The clamping block 309 gradually presses against the outer surface of the rotating disk 305, increasing the friction between the rotating disk 305 and the moving plate 207, thereby achieving precise positioning of the rotating disk 305. At this point, the two sets of angle steel bodies 1 are firmly fixed, providing stable working conditions for welding operations, effectively improving welding quality, and reducing welding defects caused by angle steel displacement.

[0039] After welding one set of angle steels, the subsequent assembly steps continue. Another set of angle steel bodies 1 is placed on top of the two already welded sets. At this point, the telescopic rod 206 and roller 205 inside the fixed housing 203 come into play. The roller 205 slides in contact with the outer surface of the angle steel body 1, reducing friction during placement, facilitating position adjustment, and providing a certain degree of restraint after placement. The spring 209 provides elastic support for the telescopic rod 206. Depending on the size of the angle steel body 1, the spring 209 adaptively extends and retracts, pushing the telescopic rod 206 to keep the roller 205 in close contact with the angle steel body 1, thus firmly clamping the upper angle steel body 1 between the two sets of angle steel bodies 1, ensuring the stability of the entire assembly structure.
