Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, and in particular to a semi-C-shaped steel positioner. Background Technology

[0002] In steel structure construction, H-beams require rotation and angle adjustment during welding to ensure accessibility and quality for all-position welding. Currently, a semi-C-shaped steel positioner is commonly used to clamp both ends of the H-beam for this rotation. Traditional semi-C-shaped steel positioners mainly consist of a frame and clamping plates at fixed heights on both sides. While these clamps grip the ends of the H-beam and rotate it, meeting basic rotation requirements, they have significant drawbacks in actual welding processes involving multiple H-beam specifications. Because the clamping plate height of traditional positioners is fixed and cannot be adjusted, when processing smaller and shorter H-beams, the clamping plate height will significantly exceed the end face height of the H-beam. The protruding part at the top of the clamping plate will form a rigid interference barrier, directly preventing the welding torch from approaching the weld. This results in some welding areas being unable to be welded normally, which not only affects welding efficiency but also easily causes quality defects such as incomplete welds, off-center welds, and incomplete welds. If the welding torch posture is forcibly adjusted to be close to the weld, it is easy to collide with the clamping plate, causing damage to the welding torch or equipment failure. At the same time, because the clamping plate height cannot be adapted to the cross-sectional height of different H-beam models, the equipment has poor versatility. Different height clamps need to be replaced for different specifications of H-beams, which is cumbersome and costly, seriously affecting the production efficiency of continuous welding of H-beams. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings mentioned above by providing a semi-C-shaped steel positioner that allows for flexible adjustment of the clamping height according to the H-shaped steel model, avoids interference with welding equipment, and has strong versatility.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a semi-C-shaped steel positioner, comprising: The support frame is installed on the track and can move along the length of the track. The first clamping mechanism includes a first support platform, on which two first clamping plates are provided, a height adjustment component for driving the two first clamping plates to move up and down, and a first spacing adjustment component for driving the two first clamping plates to move closer or further apart from each other. The first clamping mechanism also includes a rotary table and a first lifting component mounted on the rotary table for driving the first support platform to move up and down. A flipping mechanism, mounted on a bracket, is used to drive the first clamping mechanism to flip. The second clamping mechanism includes a second support platform, on which two second clamping plates are provided and a second spacing adjustment component for driving the two second clamping plates to move closer or further apart. The second clamping mechanism also includes a second lifting component disposed on a bracket and used to drive the second support platform to move up and down.

[0005] Furthermore, the height adjustment assembly includes two slides corresponding to the two first clamping plates respectively. A lead screw is rotatably mounted on the slide. The first clamping plates are slidably mounted on the corresponding slides, and a lead screw nut adapted to the lead screw is installed inside the first clamping plates. The height adjustment assembly also includes a drive component for driving the two lead screws to rotate synchronously.

[0006] Furthermore, the driving component includes two rotating shaft seats fixedly installed on the corresponding slide table. A connecting shaft is rotatably disposed inside the rotating shaft seat and passes through the rotating shaft seat. Both the connecting shaft and the corresponding lead screw are provided with bevel gears that mesh with each other. A transmission disk is provided at the end of the connecting shaft away from the bevel gear. The driving component also includes a limiting disk disposed on the slide table and capable of sliding along the axial direction of the connecting shaft. The limiting disk is sleeved with the connecting shaft and is located between the transmission disk and the rotating shaft seat. Multiple annularly distributed tooth blocks are provided on the opposite side of the transmission disk and the limiting disk. A compression spring is provided between the limiting disk and the rotating shaft seat. When the compression spring is in its natural state, the tooth blocks on the transmission disk are engaged in the adjacent tooth blocks of the limiting disk. The diameter of the transmission disk is smaller than the diameter of the limiting disk. The driving component further includes a driver disposed on the first support platform and located between the two first clamping plates. The driver includes two transmission covers. The transmission cover is provided with a groove on the side near the corresponding transmission disk with a diameter larger than the diameter of the transmission disk and smaller than the diameter of the limiting disk. A paddle is disposed in the groove. A push block is disposed on the side of the transmission disk near the transmission cover and located in the rotation area of ​​the paddle. The driver also includes a first drive motor fixedly disposed on the first support platform and a gearbox for connecting the output shaft of the first drive motor and the transmission cover.

[0007] Furthermore, the flipping mechanism includes a second drive motor mounted on the bracket, the output end of the second drive motor is provided with a gear, and the flipping mechanism also includes a half gear ring fixedly mounted on the rotary table, the half gear ring meshing with the gear.

[0008] Furthermore, the flipping mechanism also includes a braking component for locking and positioning the rotary table after it has been flipped to the target angle.

[0009] Furthermore, both the first and second clamping plates are provided with anti-slip and wear-resistant pads on their inner sides, and the surface of the anti-slip and wear-resistant pads is provided with vertical anti-slip stripes.

[0010] Furthermore, both the first support platform and the second support platform are frame structures with a hollow center.

[0011] The beneficial effects of this invention are reflected in: This invention utilizes two semi-C-shaped steel positioners installed on the rails. A first clamping mechanism clamps both ends of the H-beam. Because the height of the first clamping plate can be adjusted via a height adjustment component, it can accommodate various types of H-beams without affecting the approach of the welding torch. After welding one side of the H-beam is completed, a flipping mechanism can be used to rotate the H-beam held by the first clamping mechanism by 90 degrees. Then, a second clamping mechanism is used to temporarily clamp and position the H-beam. Afterward, the first clamping mechanism releases the clamp, and the flipping mechanism rotates the H-beam back to its original position. This clamping and flipping operation is repeated twice to complete the flipping of the H-beam. This allows the welding mechanism to perform interference-free operations on the other side of the H-beam, increasing the operational space of the welding equipment and the weldable range and angle of the components when welding steel.

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0015] Please see Figures 1-8 This invention discloses a semi-C-shaped steel positioner, comprising: Support 1 is installed on the track and can move along the length of the track; The first clamping mechanism 2 includes a first support platform 21, on which two first clamping plates 22 are provided, a height adjustment component 23 for driving the two first clamping plates 22 to move up and down, and a first spacing adjustment component 24 for driving the two first clamping plates 22 to move closer or further apart from each other. The first clamping mechanism 2 also includes a rotary table 25 and a first lifting component 26 mounted on the rotary table 25 for driving the first support platform 21 to move up and down. The flipping mechanism 3 is mounted on the bracket 1 and is used to drive the first clamping mechanism 2 to flip. The second clamping mechanism 4 includes a second support platform 41, on which two second clamping plates 42 are provided and a second spacing adjustment component 43 for driving the two second clamping plates 42 to move closer or further apart from each other. The second clamping mechanism 4 also includes a second lifting component 44 disposed on the bracket 1 and used to drive the second support platform 41 to move up and down.

[0016] This invention utilizes two semi-C-shaped steel positioners installed on the rails. A first clamping mechanism 2 clamps both ends of the H-beam. Since the first clamping plate 22 can be height-adjusted via a height adjustment component 23, it can accommodate various types of H-beams without affecting the approach of the welding torch. After welding one side of the H-beam is completed, a flipping mechanism 3 rotates the H-beam held by the first clamping mechanism 2 by 90 degrees. Then, a second clamping mechanism 4 temporarily clamps and positions the H-beam. The first clamping mechanism 2 then releases the clamp, and the flipping mechanism 3 rotates it back to its original position. This clamping and flipping operation is repeated twice to complete the flipping of the H-beam. This allows the welding mechanism to perform interference-free operations on the other side of the H-beam, increasing the operational space of the welding equipment and the weldable range and angle of the components during welding.

[0017] Specifically, the H-beam is positioned by the clamps on both sides during welding and supported by the corresponding support platform. By operating the first lifting component 26 and the second lifting component 44, the support height can be adjusted, which can avoid collision and interference between the welding equipment and the support 1 of the half C-beam positioner, and can also meet more processing needs.

[0018] In one embodiment, the height adjustment assembly 23 includes two slides 231 corresponding to the two first clamping plates 22 respectively. A lead screw 232 is rotatably mounted on the slides 231. The first clamping plates 22 are slidably mounted on the corresponding slides 231, and a lead screw nut adapted to the lead screw 232 is installed inside the first clamping plates 22. The height adjustment assembly 23 also includes a drive component for driving the two lead screws 232 to rotate synchronously.

[0019] With this design, the height adjustment component 23 adopts a "screw and nut transmission + synchronous drive" structure design, which has high adjustment accuracy and smooth lifting. It can realize the synchronous lifting of the two first clamping plates 22, ensuring that the steel is evenly stressed and horizontally positioned when clamped, thereby improving clamping stability and adjustment accuracy.

[0020] Specifically, the drive component includes two rotating shaft seats 233 fixedly mounted on the corresponding slide table 231. A connecting shaft 234 is rotatably disposed within the rotating shaft seat 233, passing through the rotating shaft seat 233. Both the connecting shaft 234 and the corresponding lead screw 232 are provided with bevel gears 235 that mesh with each other. A transmission disk 236 is provided at the end of the connecting shaft 234 away from the bevel gear 235. The drive component also includes a limiting disk disposed on the slide table 231 and capable of sliding along the axial direction of the connecting shaft 234. 237, the limiting disk 237 is sleeved with the connecting shaft 234 and is located between the transmission disk 236 and the rotating shaft seat 233. Multiple ring-shaped toothed blocks are provided on the opposite side of the transmission disk 236 and the limiting disk 237. A compression spring 238 is provided between the limiting disk 237 and the rotating shaft seat 233. When the compression spring 238 is in its natural state, the toothed blocks on the transmission disk 236 are engaged in the adjacent toothed blocks of the limiting disk 237. The diameter of the transmission disk 236 is smaller than the diameter of the limiting disk 237. The driving component also includes a driver 239 disposed on the first support platform 21 and located between the two first clamping plates 22. The driver 239 includes two transmission covers. The transmission cover is provided with a groove on the side near the corresponding transmission disk 236, with a diameter larger than the diameter of the transmission disk 236 and smaller than the diameter of the limiting disk 237. A push block is disposed in the groove. The transmission disk 236 is provided with a push block located in the rotation area of ​​the push block on the side near the transmission cover. The driver 239 also includes a first drive motor fixedly disposed on the first support platform 21 and a gearbox for connecting the output shaft of the first drive motor and the transmission cover.

[0021] This design allows part of the drive component to move synchronously with the movement of the first clamping plate 22, while the driver 239, serving as the power unit, can be fixedly mounted on the first support platform 21. When the height of the first clamping plate 22 needs to be adjusted, the first spacing adjustment component 24 drives the two first clamping plates 22 to move closer to the transmission cover, causing the limiting plate 237 to be pushed away from the transmission plate 236 by the transmission cover. Then, the first drive motor starts, allowing the transmission cover to drive the transmission plate with the push block installed under the rotation of the lever. The disk 236 rotates, thereby adjusting the height of the first clamping plate 22 through bevel gear transmission. After the height adjustment is completed, the first spacing adjustment component 24 drives the two first clamping plates 22 away from the transmission cover. The limiting disk 237 then re-engages with the transmission disk 236 under the action of the compression spring 238, ensuring that the height of the first clamping plate 22 remains unchanged during use. This drive component adopts a structure of "bevel gear transmission + tooth block meshing limit + linkage drive" to achieve synchronous drive and precise limit of the lead screw 232, taking into account both drive reliability and adjustment stability.

[0022] It should be noted that, in order to ensure that the limit plate 237 and the transmission plate 236 can be stably engaged, an inclined guide surface is provided on their opposite sides.

[0023] In one embodiment, the flipping mechanism 3 includes a second drive motor mounted on the bracket 1, and the output end of the second drive motor is provided with a gear. The flipping mechanism 3 also includes a half gear ring fixedly mounted on the rotary table 25, and the half gear ring meshes with the gear.

[0024] With this design, the flipping mechanism 3 adopts a structure of "drive motor + gear half-gear ring transmission", which provides precise transmission and sufficient driving force, enabling multi-angle flipping of the first clamping mechanism 2 to meet the needs of different processing angles of the steel profile. The gear and the half-gear ring mesh tightly with no tooth backlash deviation, resulting in high transmission efficiency. This allows for the smooth flipping of the rotary table 25 and the first clamping mechanism 2, avoiding impacts and shaking during the flipping process and ensuring the stability of the steel profile clamping posture. The half-gear ring is fixed on the rotary table 25 and rotates synchronously with it. Its arc-shaped structure is adapted to the flipping action, effectively limiting the flipping range and preventing excessive flipping that could damage the components.

[0025] In one embodiment, the flipping mechanism 3 further includes a braking component for locking and positioning the rotary table 25 after it has been flipped to the target angle.

[0026] With this design, the braking component adopts an electromagnetic braking structure, which has a fast response speed and reliable locking. It forms a linkage control with the second drive motor. When it is flipped to the target angle, the braking component is quickly activated to rigidly lock the rotary table 25, preventing the rotary table 25 from rotating due to gravity or vibration, ensuring the stability of the posture during the steel profile processing and improving the processing accuracy.

[0027] Specifically, the braking assembly has a manual unlocking function, which facilitates later maintenance and debugging, adapts to the needs of high-frequency flipping operations, and avoids safety hazards caused by brake failure.

[0028] In one embodiment, the inner sides of both the first clamping plate 22 and the second clamping plate 42 are provided with anti-slip and wear-resistant pads, and the surface of the anti-slip and wear-resistant pads is provided with vertical anti-slip stripes.

[0029] This design avoids scratches and damage to the steel surface caused by hard contact between the clamping plate and the steel profile. At the same time, it increases the static friction between the clamping plate and the steel profile, preventing the steel profile from sliding or shifting during processing and further improving clamping stability. The vertical anti-slip stripes on the surface further enhance the anti-slip effect and are suitable for steel profiles with different surface roughness. They are especially suitable for clamping smooth steel profiles and prevent slippage.

[0030] Specifically, the anti-slip and wear-resistant pads use a detachable adhesive connection, which makes them easy to replace after wear and reduces maintenance costs.

[0031] In one embodiment, both the first support platform 21 and the second support platform 41 are frame structures with a hollowed-out center.

[0032] This design can significantly reduce the overall weight of the support platform and reduce the load on bracket 1. At the same time, it facilitates the falling off of debris such as welding slag and iron filings during the steel processing, preventing them from accumulating on the support platform and affecting processing accuracy and clamping stability.

[0033] It should be noted that the first spacing adjustment component 24, the first lifting component 26, the second spacing adjustment component 43, and the second lifting component 44 are common knowledge in the field, so their specific structural composition and working principle will not be described in detail in this article.

[0034] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0035] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.
