Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure welding, specifically a mobile steel component welding fixture. Background Technology
[0002] Steel structural members refer to load-bearing and load-transferring composite steel structural members made of steel plates, angle steel, channel steel, I-beams, welded steel, or hot-rolled H-beams that are cold-bent or welded together with connectors. They primarily possess advantages such as light weight, factory manufacturing, quick installation, short construction period, good seismic performance, fast investment recovery, and low environmental pollution. Compared to reinforced concrete structures, steel structural members have unique advantages in terms of height, size, and lightness, thus enjoying reasonable and widespread application in the field of building engineering.
[0003] Current mobile steel component welding equipment, as described in patent announcement number CN216706484U, includes a support plate and a calibration plate placed between two stiffening plates inside the steel component and parallel to the stiffening plates. The surfaces of the support plate and the calibration plate are parallel and opposite to each other. A connecting rod that can be telescopically adjusted is fixedly connected between the support plate and the calibration plate. A clamping plate A is provided on the outside of the calibration plate to cooperate with the calibration plate to clamp and limit the stiffening plate to be welded.
[0004] The Ming dynasty proposed that the clamping plate A could be positioned and adjusted using screw A and nut A, thereby enabling the clamping plate A and the calibration plate to firmly and effectively clamp and position the stiffener plate to be welded. However, this method has drawbacks, namely, nut A needs to be disassembled and reassembled every time a stiffener plate is welded, which is cumbersome and causes many inconveniences to the stiffener plate welding work. Utility Model Content
[0005] The purpose of this utility model is to provide a mobile steel component welding fixture to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A mobile steel component welding fixture, including
[0008] A moving mechanism, comprising a top plate, wherein sliding blocks are symmetrically slidably passed through the interior of the top plate, and rollers are rotatably connected to the four bottom corners of the top plate;
[0009] A positioning mechanism includes a rotating shaft rotatably connected inside a set of sliding blocks. A limiting plate is fixedly connected to one side of the rotating shaft, and two limiting plates are provided. A sliding sleeve is slidably connected to the outer side of the rotating shaft. A limiting bolt is threadedly connected to one side of the sliding sleeve, and the limiting bolt abuts against the rotating shaft. Positioning rods are symmetrically fixedly connected to the bottom of the sliding sleeve. A pressure rod is slidably connected inside the positioning rod. A fixing ring is fixedly connected to the outer side of the rotating shaft. A torsion spring is fixedly connected between the fixing ring and the sliding block. A lever is fixedly connected to the outer side of the fixing ring.
[0010] As a further embodiment of this utility model: the top plate is internally rotatably connected to a bidirectional screw, and both sets of sliding blocks are threadedly connected to the bidirectional screw.
[0011] As a further embodiment of this utility model: multiple second ball bearings are movably connected to the opposite sides of the two sets of limiting plates and the opposite sides of the two sets of positioning rods.
[0012] As a further embodiment of this utility model: multiple first balls are evenly and movably connected to the opposite sides of the two sets of sliding blocks, and each set of first balls is in contact with the top plate.
[0013] As a further embodiment of this utility model: a fixing block is fixedly connected between the two sets of positioning rods, and an adjusting screw is threadedly connected inside the fixing block, and the adjusting screw is rotatably connected to the pressure rod.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] With the above-described structure, this invention utilizes the interplay of positioning rods, pressure rods, limiting plates, and torsion springs. The elasticity of the torsion springs drives the fixed ring and rotating shaft to rotate. As the rotating shaft rotates, it drives the limiting plates, sliding sleeve, positioning rods, and pressure rods to rotate as well. This causes the two sets of limiting plates to rotate to the previous set of welded ribs, while the two sets of positioning rods rotate to both sides of the rib to be welded. Simultaneously, the pressure rods rotate to abut against the rib to be welded, thus limiting the rib to be welded. After the rib is welded, simply rotating the rotating shaft disengages the two sets of positioning rods and pressure rods from the rib, releasing the rib from its limiting position. This eliminates the need to tighten nuts to limit and release the rib to be welded, making welding more convenient. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0023] Please see Figure 1-4 A movable steel component welding fixture includes a moving mechanism 1. The moving mechanism 1 includes a top plate 101, with rollers 104 rotatably connected to the four corners of the bottom of the top plate 101. The rollers 104 facilitate the movement of the top plate 101. Sliding blocks 103 are symmetrically slidably passed through the interior of the top plate 101. A bidirectional screw 102 is rotatably connected to the interior of the top plate 101. Both sets of sliding blocks 103 are threadedly connected to the bidirectional screw 102. The bidirectional screw 102 is used to drive the two sets of sliding blocks 103 to move relative to or away from each other during rotation, so as to accommodate I-beams of different widths.
[0024] Multiple first ball bearings 105 are evenly and movably connected to the opposite sides of two sets of sliding blocks 103. Each set of first ball bearings 105 is in contact with the top plate 101. The first ball bearings 105 are configured to roll along both sides of the I-beam when the sliding block 103 moves with the top plate 101, thereby reducing wear between the sliding block 103 and the I-beam. The positioning mechanism 2 includes a rotating shaft 201 rotatably connected inside a set of sliding blocks 103. A limit plate 202 is fixedly connected to one side of the rotating shaft 201. Two limit plates 202 are provided. The two sets of limit plates 202 are configured to rotate synchronously with the rotating shaft 201, thereby rotating to both sides of the welded stiffener to restrict the left and right movement of the entire fixture.
[0025] A sliding sleeve 205 is slidably connected to the outer side of the rotating shaft 201. A limit bolt 209 is threadedly connected to one side of the sliding sleeve 205, and the limit bolt 209 abuts against the rotating shaft 201. The limit bolt 209 is designed to restrict the movement of the sliding sleeve 205 when it is tightened to abut against the rotating shaft 201. Positioning rods 204 are symmetrically fixedly connected to the bottom of the sliding sleeve 205. The two sets of positioning rods 204 are designed to limit the left and right sides of the stiffening plate to be welded. A pressure rod 208 is slidably connected inside the positioning rod 204. The pressure rod 208 is designed to limit the side of the stiffening plate to be welded away from the I-beam.
[0026] A fixing block 206 is fixedly connected between the two sets of positioning rods 204. An adjusting screw 207 is threadedly connected inside the fixing block 206. The adjusting screw 207 is rotatably connected to the pressure rod 208. The adjusting screw 207 is designed to drive the pressure rod 208 to move when rotated, so that the pressure rod 208 can limit the movement of ribs of different widths. A fixing ring 210 is fixedly connected to the outside of the rotating shaft 201. A torsion spring 211 is fixedly connected between the fixing ring 210 and the sliding block 103. The torsion spring 211 is designed to limit the rotation of the fixing ring 210 and the rotating shaft 201 using its elasticity, so that the pressure rod 208 remains pressed against the rib to be welded. A lever 212 is fixedly connected to the outside of the fixing ring 210. The lever 212 is designed to facilitate the rotation of the rotating shaft 201. Multiple second balls 203 are movably connected to the opposite sides of the two sets of limiting plates 202 and the opposite sides of the two sets of positioning rods 204. The second balls 203 are provided to reduce the friction between the positioning rods 204 and the limiting plates 202 and the stiffeners.
[0027] In use, place the top plate 101 on top of the I-beam and ensure that each set of rollers 104 is in contact with the top of the I-beam. Then, rotate the double-acting screw 102, causing it to drive the two sets of sliding blocks 103 to move relative to each other until the first balls 105 on both sides move with the sliding blocks 103 to contact the I-beam. Next, loosen the limiting bolts 209 to adjust the welding spacing between the two adjacent stiffeners as needed. Then, slide the sliding sleeve 205, causing it to drive the two sets of positioning rods 204 to move until they are in the desired positions. Then, tighten the limiting bolts 209 until they abut against the rotating shaft 201, thus limiting the positioning rods 204. Next, move the lever 212, causing it to drive the fixing ring 210 and the rotating shaft 201 to rotate, thereby causing the limiting plate 202 and the positioning rods 204 to rotate as well, until the limiting plate 202 is rotated out of the groove of the I-beam. Then, the top plate 101 can be pushed to move, causing each set of rollers 104 to roll on the top of the I-beam. When the rollers move to the position corresponding to the previous set of welded stiffeners in the area between the two sets of limiting plates 202, the next stiffener to be welded is placed in the groove of the I-beam, and the next stiffener to be welded is positioned in the area between the I-beam and the two sets of positioning rods 204. Then, the lever 212 is released, causing the torsion spring 211 to return to its deformation, thereby driving the fixing ring 210 and the rotating shaft 201 to rotate. When the rotating shaft 201 rotates, it can drive the limiting plate 202, the sliding sleeve 205, the positioning rods 204 and the pressure rod 208 to rotate as well, so that the two sets of limiting plates 202 rotate to the previous set of welded stiffeners, and the two sets of positioning rods 204 can rotate to both sides of the stiffener to be welded. At the same time, the pressure rod 208 rotates to abut against the stiffener to be welded, thereby achieving the limiting of the stiffener to be welded. After that, the stiffener to be welded can be welded.
[0028] The above-described embodiments are preferred embodiments of the present utility model and are only used to facilitate the illustration of the present utility model. They are not intended to limit the present utility model in any way. Any person skilled in the art who makes partial modifications or alterations to the technical content disclosed in the present utility model without departing from the scope of the technical features of the present utility model shall still fall within the scope of the technical features of the present utility model.
