Description

Technical Field

[0001] This utility model relates to the field of welding positioning and calibration technology, specifically to a positioning and calibration device for steel structure welding and installation. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure mainly consists of beams, columns, trusses, and other components made of shaped steel and steel plates. Rust removal and prevention processes such as silanization, pure manganese phosphating, washing and drying, and galvanizing are used. The components are typically connected by welds, bolts, or rivets. Due to their light weight and ease of construction, they are widely used in large factories, stadiums, and high-rise buildings. Steel structures are prone to corrosion, and generally require rust removal, galvanizing, or painting, as well as regular maintenance.

[0003] When using a welding positioning and calibration device to fix and weld a round pipe, in addition to fixing the round pipe, it is also necessary to consider positioning and calibrating the round pipe during fixing. To this end, Chinese Patent Publication No. CN219986633U provides a steel structure connection calibration device. By setting a fixing component, the steel structure is placed in the installation frame. When the clamp is released, the spring is pushed back and pushes the clamp downward until it contacts the steel structure, thus completing the fixing of the steel structure. At this time, the two steel structures are on the same horizontal plane, thereby assisting people in calibrating and connecting the steel structures.

[0004] However, in actual use cases, due to the special manufacturing characteristics of the fixture, round tubes of the same type are usually on the same horizontal plane when clamped. What needs more attention is the calibration of the XY axis distance. Therefore, this welding positioning calibration device lacks the function of positioning and calibrating the workpiece in the radial direction of the clamping table. The workpiece offset in the radial direction cannot be corrected, resulting in uneven weld width or even cracking during subsequent welding, and the product quality does not meet the standards. Utility Model Content

[0005] This utility model provides a positioning and calibration device for welded installation of steel structures. It solves the problems mentioned in the background art by dividing the clamping mechanism into a fixed seat and a movable seat. During calibration, the movable seat is moved along the clamping groove by a first rotating mechanism to precisely fix its position.

[0006] The positioning and calibration device lacks the function of positioning and calibrating the workpiece radially on the clamping table, which makes it impossible to correct the workpiece offset, resulting in uneven width and cracking of the subsequent weld.

[0007] To achieve the above objectives, the welding positioning and calibration device includes a positioning mechanism, a clamping mechanism, and a calibration mechanism. The clamping mechanism includes an arc-shaped plate, the bottom of which is rotatably connected to a fixed base via an elastic element.

[0008] The fixing seat is located on the horizontal plate above the base and is fixed to the horizontal plate by multiple bolts;

[0009] On the side above the horizontal plate corresponding to the fixed seat, there is a movable seat that slides inside the clamping groove via a slider.

[0010] The arc-shaped plate has a roller mounted inside on the side closest to the first screw.

[0011] In the above technical solution, the fixed seat is fixedly installed on one side of the horizontal plate, and the movable seat on the other side clamps the workpiece by sliding the slider inside the clamping groove. The arc plate fixes the upper part of the workpiece when it is placed in through the elastic action of the elastic element, and the rollers at the bottom of the arc plate make the workpiece more stable through the combined action of all directions.

[0012] Based on this, a first screw is threadedly connected to the threaded slot at the center of one side of the fixed seat and the movable seat, and a first rotator is rotatably connected to the end of the first screw near the fixed seat, which is used to make the movable seat move radially along the clamping slot to clamp the workpiece when the first rotator is rotated.

[0013] The fixed seat and the movable seat are distributed in two sets along the radial direction of the second screw, and the movable seat is provided with an infrared positioner on the side near the center of the base;

[0014] When clamping the workpiece, the first rotator drives the first screw to rotate, causing the movable seat to move closer to the fixed seat. The separate fixed seat and movable seat can also accommodate round pipes of more diameters and asymmetrical workpieces. When the infrared positioner laser on one side of the movable seat corresponds, the movable seats on both sides are in the positioning completed state, and the welding process can be carried out.

[0015] In another technical solution, the calibration mechanism includes a second screw, which is located in a slot opened at the center above the base, and both ends of the second screw pass through both sides of the base and are rotatably connected to the second rotator;

[0016] The second screw is connected to the raised thread on the bottom of the horizontal plate on the outer side of the part located in the slot of the base. The rotation of the second screw causes the two horizontal plates with fixed seats and movable seats to move towards each other, so that the workpieces on both sides are tightly connected, avoiding excessive weld seam due to distance deviation.

[0017] The welding positioning calibration device also includes a first scale and a second scale. The second scale is used to observe the distance moved when the movable seat is moved towards the fixed seat, forming a second calibration process in conjunction with the infrared locator, so as to improve the calibration effect. The first scale is used to observe the distance moved when the clamping cross plates on both sides move towards each other.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] By dividing the clamping mechanism into a fixed seat and a movable seat, during calibration, the movable seat is moved along the clamping groove to a precise fixed position by the first rotator. The precise control of the rotation angle by the first rotator, in conjunction with the infrared positioner, enables more accurate control of the positioning and calibration function of the clamping mechanism. Furthermore, calibration can be performed at any time when the workpiece is radially offset. During subsequent welding work, the weld is more uniform. The single-sided movable seat design reduces the number of moving parts, making calibration more accurate. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Currently, positioning and calibration devices lack radial calibration functionality for the workpiece within the clamping table, leading to uncorrectable workpiece misalignment and subsequent uneven weld width and cracking. This invention provides a positioning and calibration device for steel structure welding and installation. (See [link to relevant documentation]). Figure 2 and Figure 4 As shown, it includes a positioning mechanism 100, a clamping mechanism 200 and a calibration mechanism 300. The clamping mechanism 200 includes an arc plate 204, and the bottom of the arc plate 204 is rotatably connected to the fixed base 201 through an elastic member 205.

[0030] The mounting base 201 is located on the horizontal plate above the base 101 and is fixed to the horizontal plate by multiple bolts;

[0031] On the side of the horizontal plate corresponding to the fixed seat 201, there is a movable seat 202 that slides inside the clamping groove 104 via a slider. A roller 206 is rotatably installed inside the side of the arc plate 204 near the first screw 207. The sliders on both sides of the bottom of the horizontal plate slide inside the docking groove 103.

[0032] During implementation, the arc plate 204 is rotatably connected to the fixed base 201 through the elastic element 205 at the bottom. When the workpiece is placed in, the arc plate 204 automatically adheres to the surface of the workpiece under the elastic force of the elastic element 205, forming a preliminary fixation. The roller 206 installed on the inner side of the arc plate 204 can roll with the surface of the workpiece, reducing frictional resistance, while evenly distributing the clamping force, avoiding damage to the surface of the workpiece, and enhancing clamping stability.

[0033] See Figure 4 As shown, a first screw 207 is threadedly connected to a threaded slot at the center of one side of the fixed seat 201 and the movable seat 202. A first rotator 203 is rotatably connected to the end of the first screw 207 near the fixed seat 201. When the first rotator 203 is rotated, the movable seat 202 moves radially along the clamping slot 104 to clamp the workpiece. When the first rotator 203 is rotated, the first screw 207 drives the movable seat 202 to move radially along the clamping slot 104 through threaded transmission, pushing the movable seat 202 closer to the fixed seat 201, thereby radially clamping the workpiece. The separate design of the fixed seat 201 and the movable seat 202 can adapt to round pipes of different diameters or asymmetrical workpieces. Flexible clamping can be achieved by adjusting the stroke of the first screw 207.

[0034] Figure 2 In the middle, there are two sets of fixed seat 201 and movable seat 202 radially distributed along the second screw 302, and an infrared positioner 208 is provided on the side of the movable seat 202 near the center of the base 101. When the infrared lasers of the two movable seats 202 are aligned, it indicates that the workpiece clamping position has been calibrated and can directly enter the welding process.

[0035] Additionally, see Figures 3-4As shown, the calibration mechanism 300 includes a second screw 302, which is located in a slot at the center of the upper part of the base 101. The two ends of the second screw 302 pass through both sides of the base 101 and are rotatably connected to the second rotator 301. The outer side of the part of the second screw 302 located in the slot of the base 101 is threadedly connected to the protrusion at the bottom of the horizontal plate. When the second rotator 301 is rotated, the second screw 302 drives the protrusion structure at the bottom of the horizontal plates on both sides to move along the axial direction of the second screw 302. By rotating the second screw 302 in both directions, the horizontal plates on both sides can move towards each other or in opposite directions, thereby accurately adjusting the docking distance of the workpieces on both sides, ensuring that the weld is tight and without deviation, and ensuring that the workpieces on both sides are symmetrically aligned.

[0036] Figure 3 In the middle, a first scale 102 with the center point of the edge line as the origin is provided above the base 101. It is used to measure the distance that the two horizontal plates move towards each other to ensure symmetry. A second scale 209 with the edge of the fixed seat 201 as the origin is provided above the horizontal plate. It is used to observe the distance that the movable seat 202 moves towards the fixed seat 201. Combined with the infrared locator 208, a dual calibration mechanism is formed to improve accuracy.

[0037] Working principle: First, when the worker places the workpiece between the two fixed seats 201 and the movable seat 202, when the first rotator 203 is rotated, the first screw 207 drives the movable seat 202 to move radially along the clamping groove 104 through the threaded transmission, pushing the movable seat 202 closer to the fixed seat 201, thereby radially clamping the workpiece. The separate design of the fixed seat 201 and the movable seat 202 can adapt to round pipes of different diameters or asymmetrical workpieces. Flexible clamping can be achieved by adjusting the stroke of the first screw 207.

[0038] The arc plate 204 automatically adheres to the workpiece surface under the elastic force of the elastic element 205, forming a preliminary fixation. The roller 206 installed on the inner side of the arc plate 204 can roll with the workpiece surface, reducing frictional resistance, while evenly distributing the clamping force, avoiding damage to the workpiece surface, and enhancing clamping stability.

[0039] When the second rotator 301 is rotated, the second screw 302 drives the protruding structure at the bottom of the two horizontal plates to move along the axis of the second screw 302. By rotating the second screw 302 in both directions, the two horizontal plates can move towards each other or in opposite directions, thereby precisely adjusting the docking distance of the workpieces on both sides, ensuring that the weld is tight and without deviation, and ensuring that the workpieces on both sides are symmetrically aligned.

[0040] When the infrared lasers of the two movable seats 202 are aligned, it indicates that the workpiece clamping position has been calibrated and can proceed directly to the welding process.

[0041] The first scale 102 and the second scale 209 are used to measure the distance the two horizontal plates move towards each other, ensuring symmetry and to observe the distance the movable seat 202 moves towards the fixed seat 201. Combined with the infrared locator 208, they form a dual calibration mechanism to improve accuracy.
