Description

Technical Field

[0001] This utility model relates to the field of construction machinery technology, and in particular to an auxiliary mechanism for squaring angle steel. Background Technology

[0002] In modern manufacturing, especially in the assembly and welding of steel structures, the production efficiency and welding quality of square angle steel are directly related to the performance and reliability of the final product. Therefore, improving the assembly accuracy and welding quality of square angle steel is a technical problem that urgently needs to be solved in the industry.

[0003] The existing manufacturing process mainly relies on manual operation, using simple clamps to fix two square angle steels together. This fixing method only constrains the square angle steels in the vertical direction, while the horizontal direction is constrained by a point at a certain interval. This method cannot effectively control the straightness of the entire square angle steel. As a result, during the welding process, the square angle steels are relatively free in the horizontal direction, making it impossible to maintain a good alignment, which increases the risk of failing to meet the straightness standards. In addition, the square angle steels may twist or deform due to factors such as thermal expansion and contraction, resulting in straightness defects in the final welded part.

[0004] To address this issue, an auxiliary mechanism for squaring angle steel is proposed to solve the problems existing in the current technology. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems by providing an auxiliary mechanism for squaring angle steel. This utility model uses vertical and horizontal clamping mechanisms on an auxiliary trolley to constrain the vertical and horizontal degrees of freedom of the squaring angle steel. Combined with a roller mechanism, this allows the welding torch to move linearly with the auxiliary trolley, completing the squaring welding operation. This prevents the squaring angle steel from shifting, which could lead to substandard straightness or warping in certain areas. It also prevents welding problems that would necessitate re-welding, thus improving the stability of the squaring welding quality. To achieve the above-mentioned utility model objectives, the technical solution adopted is as follows:

[0006] According to one aspect of this utility model, an auxiliary mechanism for squaring angle steel is provided, including a base frame, the base frame being a frame welded from multiple square tubes, an auxiliary trolley being provided on the top of the base frame, the auxiliary trolley having an inverted U-shape and being placed entirely on the base frame, a roller mechanism being provided at the lower end of the auxiliary trolley, the roller mechanism consisting of two rollers spaced apart in a vertical direction, each roller being placed at the upper and lower ends of the square tube at the upper end of the base frame, i.e., the two rollers clamping the square tube, the auxiliary trolley being provided with a vertical clamping mechanism and a horizontal clamping mechanism, the vertical clamping mechanism being located at the upper end of the auxiliary trolley and the horizontal clamping mechanism being located in the middle of the auxiliary trolley.

[0007] Preferably, the vertical clamping mechanism includes a vertical hydraulic cylinder vertically mounted on the top of the auxiliary trolley. The output end of the vertical hydraulic cylinder is provided with a connecting seat, and a pressure plate is provided on the connecting seat. The pressure plate is connected to the connecting seat through a connecting shaft, and a pin is provided on the connecting shaft. The pressure plate is V-shaped, and an inverted V-groove is provided at the lower end of the pressure plate.

[0008] Preferably, the horizontal clamping mechanism includes a horizontal hydraulic cylinder disposed in the middle of the auxiliary trolley. The output end of the horizontal hydraulic cylinder is provided with a connector. Two connecting rods are symmetrically connected to the connector. The other end of each connecting rod is connected to a mounting seat. Two connecting brackets are provided in the middle of the auxiliary trolley, and the centers of the two connecting brackets are hinged through a bushing. The two connecting brackets are arranged crosswise. Each connecting bracket is provided with a mounting seat near the outer wall of the horizontal hydraulic cylinder.

[0009] Preferably, each of the connecting brackets has an arc-shaped groove on its inner sidewall, and the two arc-shaped grooves of the side wheel cooperate with the vertical hydraulic cylinder.

[0010] Preferably, the base frame is provided with a support plate at the top, the support plate is provided with a support block, and the top of the support block is provided with a V-shaped groove.

[0011] Preferably, each of the roller mechanisms is provided with a side wheel on its side.

[0012] Preferably, the auxiliary trolley has an auxiliary wheel on the side near the vertical clamping mechanism at its upper end.

[0013] Preferably, one end of the base frame is provided with an end connector, that is, the two bases are extended by splicing the end connector and the pin.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0015] 1. The angle steel squaring auxiliary mechanism described in this utility model constrains the vertical and horizontal degrees of freedom of the squaring angle steel through the vertical and horizontal clamping mechanisms on the auxiliary trolley. In conjunction with the roller mechanism, the welding torch moves linearly with the auxiliary trolley to complete the squaring welding operation. This avoids the squaring angle steel from shifting, which could lead to substandard straightness or warping in certain parts. It also prevents welding problems in the squaring angle steel that would require re-welding, thus improving the stability of the angle steel squaring welding quality.

[0016] 2. The angle steel squaring auxiliary mechanism of this utility model, by setting side wheels perpendicular to the side of the base frame on the roller mechanism, cancels out the lateral component of the downward pressure applied to the auxiliary trolley during welding, plays the role of side support, avoids deviation during linear welding, and improves the stability during welding.

[0017] 3. The angle steel squaring auxiliary mechanism described in this utility model has an auxiliary wheel between the auxiliary trolley and the squaring angle steel. The auxiliary wheel can rotate on its own. During the linear movement, while the squaring angle steel is restricted by the vertical clamping mechanism and the horizontal clamping mechanism, the auxiliary wheel can provide a certain guiding effect at its top, reducing the friction and jerking between the auxiliary trolley and the squaring angle steel, and making the linear movement of the auxiliary trolley smoother.

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided with reference to the accompanying drawings and preferred embodiments. However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of the utility model, and these aspects can be achieved even without these specific details.

[0030] Please see Figures 1 to 7 This utility model provides an auxiliary mechanism for squaring angle steel, the technical solution of which is as follows:

[0031] The system includes a base frame 1, which is a frame welded from multiple square tubes. An auxiliary trolley 2 is provided on the top of the base frame 1. The auxiliary trolley 2 has an inverted U-shaped structure and is placed entirely on the base frame 1. A roller mechanism 3 is provided at the lower end of the auxiliary trolley 2. The roller mechanism 3 consists of two rollers 3 spaced apart in the vertical direction. Each roller 3 is placed at the upper and lower ends of the square tube at the top of the base frame 1, that is, the two rollers 3 clamp the square tube. The auxiliary trolley 2 is provided with a vertical clamping mechanism 4 and a horizontal clamping mechanism 5. The vertical clamping mechanism 4 is located at the upper end of the auxiliary trolley 2, and the horizontal clamping mechanism 5 is located in the middle of the auxiliary trolley 2.

[0032] When welding existing square angle steel, operators generally only constrain the vertical degree of freedom and only spot weld in the horizontal direction. However, during linear movement welding, the strength of spot welding may not be sufficient to support the welding pressure between the square angle steel, which can easily lead to misalignment between the square angle steel, resulting in non-compliance with straightness standards or warping in some parts. This requires re-welding, which is time-consuming and labor-intensive.

[0033] The operators first hoist the square angle steel to the base frame 1. Then, by operating the roller mechanism 3 on the auxiliary trolley 2, they move the auxiliary trolley 2 to the top of the square angle steel. Next, they sequentially activate the vertical clamping mechanism 4 and the horizontal clamping mechanism 5 to constrain the vertical and horizontal degrees of freedom of the square angle steel, respectively. Then, the welding torch follows the auxiliary trolley 2 in a linear forward movement to weld the gap to be spliced, completing the splicing operation. By using the vertical clamping mechanism 4 and the horizontal clamping mechanism 5 on the auxiliary trolley 2 to constrain the vertical and horizontal degrees of freedom of the square angle steel, and in conjunction with the roller mechanism 3, the welding torch moves linearly with the auxiliary trolley 2 to complete the splicing operation. This prevents the square angle steel from shifting, which could lead to substandard straightness or warping in certain parts, and avoids welding problems that would require re-welding, thus improving the stability of the angle steel splicing welding quality.

[0034] The vertical clamping mechanism 4 includes a vertical hydraulic cylinder 401 vertically mounted on the top of the auxiliary trolley 2. The output end of the vertical hydraulic cylinder 401 is provided with a connecting seat 402. A pressure plate 403 is provided on the connecting seat 402. The pressure plate 403 is connected to the connecting seat 402 through a connecting shaft 404. A pin 405 is provided on the connecting shaft 404. The pressure plate 403 is V-shaped, and an inverted V-groove 406 is provided at the lower end of the pressure plate 403. A support plate 6 is provided on the top of the base frame 1. A support block 7 is provided on the support plate 6, and a V-groove 8 is provided on the top of the support block 7.

[0035] The vertical hydraulic cylinder 401 drives the pressure plate 403 to move downward through the connecting seat 402. The lower end of the pressure plate 403 is provided with an inverted V-groove 406, and the shape of the inverted V-groove 406 is consistent with the side angle of the square angle steel. Thus, the pressure plate 403 moves downward against the square angle steel. Since the base frame 1 is provided with a support block 7, and the top of the support block 7 is provided with a V-groove 8, and this V-groove 8 is consistent with the side angle of the square angle steel, when the operator hoists, the square angle steel is placed sideways in the V-groove 8 of the support block 7. With the vertical hydraulic cylinder 401 driving the pressure plate 403 to move downward, the inverted V-groove 406 and the V-groove 8 cooperate to fix the square angle steel in the vertical direction, restricting its vertical freedom. With the horizontal clamping mechanism 5, the square angle steel is fixed as a whole. Then welding is carried out to avoid the square angle steel from shifting and causing the straightness to fail to meet the standard, thus improving the stability of the welding.

[0036] The pressure plate 403 is connected to the connecting seat 402 via the connecting shaft 404 and the pin 405. That is, the pressure plate 403 has a certain rotation angle relative to the connecting seat 402 and is not completely fixed. When the pressure plate 403 contacts the square angle steel, the V-groove 406 plays a certain guiding role. Together with the pressure plate 403 which can rotate at a certain angle, the pressure plate 403 can stably fit with the square angle steel and has a certain function of straightening the square angle steel, thus improving the efficiency of the preparation work before welding.

[0037] The horizontal clamping mechanism 5 includes a horizontal hydraulic cylinder 501 disposed in the middle of the auxiliary trolley 2. The output end of the horizontal hydraulic cylinder 501 is provided with a connector 502. Two connecting rods 503 are symmetrically connected to the connector 502. The other end of each connecting rod 503 is connected to a mounting base 504. Two connecting brackets 505 are provided in the middle of the auxiliary trolley 2. The centers of the two connecting brackets 505 are hinged through a bushing 506. The two connecting brackets 505 are arranged crosswise. Each connecting bracket 505 is provided with a mounting base 504 near the outer wall of the horizontal hydraulic cylinder 501.

[0038] The two connecting brackets 505 are hinged by the bushing 506. When the horizontal hydraulic cylinder 501 extends and retracts, the two connecting brackets 505 rotate around the bushing 506, thereby restricting the horizontal freedom of the square angle steel and preventing the square angle steel from shifting in the horizontal direction. Together with the vertical clamping mechanism 4, the square angle steel to be spliced ​​can be stabilized, making it convenient for subsequent operators to weld the splice with a welding gun, preventing the straightness from not meeting the standard or the warping of certain parts, and improving the stability during splicing.

[0039] Each connecting bracket 505 has an arc-shaped groove 507 on its inner sidewall. The two arc-shaped grooves 507 of the side wheel 9 cooperate with the vertical hydraulic cylinder 401. The square angle steel to be welded is relatively long, and ordinary horizontal clamping methods are not suitable for it. By providing arc-shaped grooves 507 on the two connecting brackets 505, and splicing the two arc-shaped grooves 507 together to form an arc groove, the size of which is consistent with the diameter of the output shaft of the vertical hydraulic cylinder 401, after the vertical hydraulic cylinder 401 drives the pressure plate 403 to restrict the square angle steel in the vertical direction, the horizontal hydraulic cylinder 501 drives the two connecting brackets 505 to tighten. The two arc-shaped grooves 507 clamp the output shaft of the vertical hydraulic cylinder 401. Under the premise of ensuring the stable operation of the vertical clamping mechanism, this method restricts the horizontal degree of freedom of the entire square angle steel, which helps the subsequent welding operation, prevents the straightness from not meeting the standard or the warping of certain parts, and improves the stability during welding.

[0040] Each of the roller 3 mechanisms is equipped with a side wheel 9 on its side. When the operator performs linear welding of the square angle steel with the welding torch and the auxiliary carriage 2, there will be a downward squeezing force on the square angle steel and the auxiliary carriage 2. The square angle steel is restricted in its vertical and horizontal degrees of freedom by the vertical clamping mechanism 4 and the horizontal clamping mechanism 5. The auxiliary carriage 2 can only be fixed by the clamping force between the roller 3 mechanism and the base frame 1. By setting a side wheel 9 perpendicular to the side of the base frame 1 on the side of each roller 3 mechanism, the lateral component of the downward pressure on the auxiliary carriage 2 during welding is offset, which plays a role in side support, avoids the situation of displacement during linear welding, and improves the stability during welding.

[0041] The auxiliary trolley 2 is equipped with an auxiliary wheel 10 on the side near the vertical clamping mechanism 4 at its upper end. When linearly welding the square angle steel, the vertical clamping mechanism 4 at the top restricts the square angle steel, causing the auxiliary trolley 2 to experience some jerking during linear movement. The auxiliary wheel 10 on the auxiliary trolley 2 allows it to rotate on its own. During linear movement, while the square angle steel is restricted by the vertical clamping mechanism 4 and the horizontal clamping mechanism 5, the auxiliary wheel 10 at its top provides some guidance, reducing friction and jerking between the auxiliary trolley 2 and the square angle steel, and allowing the auxiliary trolley 2 to move more smoothly.

[0042] One end of the base frame 1 is equipped with an end connector 11, that is, the two bases are spliced ​​and extended through the end connector 11 and the pin 12; the base frame 1 is a spliced ​​base frame 1, and the length of one base frame 1 is 7.5 meters. When splicing and welding long square angle steel, the corresponding number of base frames 1 are arranged according to the actual length of the square angle steel, and then spliced ​​and extended through the end connector 11 and the pin 12, so that the auxiliary mechanism can adapt to the welding of square angle steel of different lengths, ensuring that the operator can stably drive the welding gun to stably weld the square angle steel through the auxiliary trolley 2, thereby improving stability and adaptability.

[0043] Workflow: Based on the actual length of the square angle steel, arrange a corresponding number of base frames 1. Then, extend multiple base frames 1 by splicing them together using end connectors 11 and pins 12. The operator hoists the square angle steel into the V-groove 8 of the support block 7 at the top of the base frame 1. Then, the vertical hydraulic cylinder 401 and the horizontal hydraulic cylinder 501 are activated in sequence. The vertical hydraulic cylinder 401 drives the pressure plate 403 to move downwards through the connecting seat 402 until the pressure plate 403 is in contact with the top of the square angle steel. The lower end of the pressure plate 403 has an inverted V-groove 406. The inverted V-groove 406 and the V-groove 8 cooperate to fix the square angle steel in the vertical direction, restricting its vertical freedom. At the same time, the horizontal hydraulic cylinder 501 is activated to tighten the two connecting brackets 505. The two arc grooves 507 clamp the output shaft of the vertical hydraulic cylinder 401, restricting its horizontal freedom. Then, the operator uses a welding torch to follow the auxiliary trolley 2 to move linearly and complete the splicing and welding operation.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
