Description

Technical Field

[0001] This utility model relates to the field of welding technology in mechanical manufacturing, and in particular to a bracket welding fixture that can be quickly positioned. Background Technology

[0002] Bracket welding is the process of cutting and shaping metal materials (such as steel plates and profiles) according to design requirements, and then fixing them together by welding to form an integral bracket structure. After welding, the bracket has high strength and stability and can meet specific load-bearing or support requirements.

[0003] A quick-positioning bracket welding fixture is a tool or device specifically designed to improve welding efficiency and precision. This device helps to fix the parts to be welded in the correct position by providing precise and stable positioning, thereby ensuring the consistency and quality of the welding process.

[0004] The existing bracket welding fixture with rapid positioning has the following shortcomings:

[0005] 1) Existing bracket welding often lacks a precise positioning mechanism. When manually aligning two brackets, it is difficult to ensure the accuracy and consistency of their positions, which can lead to welding position deviations. This affects the dimensional accuracy and assembly performance of the product. Secondly, inaccurate bracket alignment can cause uneven weld widths and heights, and even serious defects such as incomplete penetration and misalignment. This can lead to unstable product quality and increased scrap rate. At the same time, relying solely on simple clamps or manual support, the brackets are prone to displacement or shaking during the welding process due to external forces such as welding thermal stress and mechanical vibration, which can affect welding quality and even lead to welding failure. Utility Model Content

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] Example 1, according to Figures 1-5 As shown, this utility model provides a technical solution: a bracket welding fixture that can be quickly positioned, including a quick positioning welding component 6, a first bracket 1, and a second bracket 2, wherein the quick positioning welding component 6 is installed on the outer surface of the first bracket 1 and the second bracket 2;

[0029] The rapid positioning welding assembly 6 includes four L-plates 601. Electric cylinders 602 are fixedly mounted on the outer walls of each of the four L-plates 601. A coupling 603 is fixedly sleeved on the shaft end of each of the four electric cylinders 602. The four electric cylinders 602 convert electrical energy into mechanical energy to drive the four couplings 603 in linear motion. A slider 604 is bolted to the outer wall of each of the four couplings 603. A hydraulic cylinder 605 is fixedly mounted on one side of the outer wall of each of the four sliders 604. A metal plate 606 is fixedly sleeved on the shaft end of each of the four hydraulic cylinders 605. The four hydraulic cylinders 605 convert hydraulic energy into mechanical energy to drive the four metal plates 606 in linear motion. An arc-shaped clamping member 607 is bolted to one side of the outer wall of each of the four metal plates 606.

[0030] The overall effect achieved by embodiment 1 is as follows: By pre-setting the above components, a complete rapid positioning welding assembly 6 is formed. First, electric cylinders 602 are fixedly installed on the outer walls of the four L-plates 601. Connecting parts 603 are fixedly sleeved on the shaft ends of the four electric cylinders 602. Next, sliders 604 are bolted to the outer walls of the four connecting parts 603. Hydraulic cylinders 605 are fixedly installed on one side of the outer wall of each of the four sliders 604. Metal plates 606 are fixedly sleeved on the shaft ends of the four hydraulic cylinders 605. Arc-shaped clamping parts 607 are bolted to one side of the outer wall of each of the four metal plates 606. The four electric cylinders 602 convert electrical energy into mechanical energy to drive the four connecting parts 603 and the four sliders 604 to perform linear motion. The four hydraulic cylinders 605 convert hydraulic energy into mechanical energy to drive the four metal plates 606 and the four arc-shaped clamping parts 607 to perform linear motion. Through the above connection relationship, accurate clamping and alignment of the first bracket 1 and the second bracket 2 are achieved, thus realizing the setup of the rapid positioning welding assembly 6. By using four hydraulic cylinders 605 to clamp and fix the first bracket 1 and the second bracket 2 in opposite directions, the two brackets 1 and 2 to be welded can be quickly positioned in accurate positions. Furthermore, by using four electric cylinders 602 to drive the four hydraulic cylinders 605 and the first brackets 1 and 2 to move and align, the movement and docking of the first brackets 1 and 2 can be precisely controlled, ensuring the accuracy of the welding position and improving welding quality and consistency. At the same time, the clamping force provided by the four hydraulic cylinders 605 is uniform and stable, ensuring that the brackets will not shift or shake due to external forces or welding deformation during the welding process, thus guaranteeing the stability of the welding process and the quality of the weld. Moreover, the coordinated work of the four electric cylinders 602 and the four hydraulic cylinders 605 automates the positioning and clamping process of the first brackets 1 and 2, reducing manual operation, lowering the labor intensity of workers, improving production efficiency, and reducing quality instability caused by human error.

[0031] Example 2, according to Figures 1-5As shown, the inner surfaces of the four arc-shaped clamping parts 607 are all covered with anti-slip silicone sleeves 608, and the outer surfaces of the four anti-slip silicone sleeves 608 are provided with anti-slip textures. Each pair of arc-shaped clamping parts 607 is symmetrically placed. Four springs 609 are fixedly connected to the outer walls of each pair of arc-shaped clamping parts 607. Fixing plates 3 are provided on both sides of the outer wall of the first bracket 1, and the two fixing plates 3 are symmetrically placed. Two metal connecting blocks 4 are bolted to one side of the outer wall of each pair of fixing plates 3, and each pair of metal connecting blocks 4 is symmetrically placed. A cross brace 5 is bolted to the top of each pair of metal connecting blocks 4. The two fixing plates... Both ends of the outer wall of the 3 are bolted to a corresponding L plate 601. A groove is provided on one side of the outer wall of the two fixing plates 3. Each pair of sliders 604 are slidably connected in the corresponding groove. There is a ring of movable space between the four anti-slip silicone sleeves 608 and the outer surfaces of the corresponding first bracket 1 and second bracket 2. Eight springs 609 are elastically connected to a corresponding opposing arc-shaped clamping member 607. The eight springs 609 can provide elastic deformation for the four arc-shaped clamping members 607. A ring of movable space is formed between the first bracket 1 and the second bracket 2. Each pair of electric cylinders 602 are placed opposite each other.

[0032] The overall effect achieved by embodiment 2 is as follows: By pre-setting the above components, the inner surfaces of the four arc-shaped clamping members 607 are first covered with anti-slip silicone sleeves 608, and the outer surfaces of the four anti-slip silicone sleeves 608 are provided with anti-slip textures. Every two arc-shaped clamping members 607 are placed symmetrically, and four springs 609 are fixedly connected to the outer walls of the two arc-shaped clamping members 607. The surface of the anti-slip silicone sleeves 608 has a certain roughness and stickiness, which can closely fit the surfaces of the clamped first bracket 1 and second bracket 2, effectively increasing friction. The force prevents the first bracket 1 and the second bracket 2 from sliding during clamping, ensuring accurate positioning and improving welding quality. The anti-slip silicone sleeve 608 is soft and can prevent the arc-shaped clamping part 607 from directly contacting the first bracket 1 and the second bracket 2, preventing scratches or damage to the surfaces of the first bracket 1 and the second bracket 2 during clamping. Secondly, the spring 609 is elastic and can play a buffering role when the arc-shaped clamping part 607 clamps the first bracket 1 and the second bracket 2, avoiding excessive clamping force that could damage the first bracket 1 and the second bracket 2.

[0033] The working principle of the entire equipment is as follows: During the installation phase, the components to be assembled are placed in a safe area to provide a safe assembly environment for subsequent assembly. First, fixing plates 3 are installed on both sides of the outer wall of the first support 1, with the two fixing plates 3 placed symmetrically. Two metal connecting blocks 4 are bolted to one side of the outer wall of each of the two fixing plates 3, and each pair of metal connecting blocks 4 is placed symmetrically. A cross brace 5 is bolted to the top of each pair of metal connecting blocks 4. Next, both ends of the outer wall of each of the two fixing plates 3 are bolted to a corresponding L-plate 601. Then, electric cylinders 602 are fixedly installed on the outer walls of the four L-plates 601. Each shaft end is fixedly fitted with a connecting piece 603. Then, a slider 604 is bolted to the outer wall of each of the four connecting pieces 603. A hydraulic cylinder 605 is fixedly installed on one side of the outer wall of each of the four sliders 604. A metal plate 606 is fixedly fitted to the shaft end of each of the four hydraulic cylinders 605. An arc-shaped clamping piece 607 is bolted to one side of the outer wall of each of the four metal plates 606. An anti-slip silicone sleeve 608 is covered on the inner surface of each of the four arc-shaped clamping pieces 607. The outer surface of each of the four anti-slip silicone sleeves 608 is provided with anti-slip texture. Each pair of arc-shaped clamping pieces 607 is placed symmetrically. Four springs 609 are fixedly connected to the outer wall of each pair of arc-shaped clamping pieces 607.

[0034] The working principle of this device is as follows: The working stages are as follows: After all components are assembled, check whether each component is properly installed and fixed, ensuring there is no looseness. Once confirmed, connect the external power supply to the required power source. First, place the first bracket 1 and the second bracket 2 to be welded on the workbench, ensuring their position is convenient for subsequent operations. Next, activate four hydraulic cylinders 605 via the external power supply. Under hydraulic pressure, two opposing arc-shaped clamping parts 607 move towards the first bracket 1 and the second bracket 2. The anti-slip silicone sleeve 608 on the inner surface of the arc-shaped clamping part 607 contacts the surfaces of the first bracket 1 and the second bracket 2. The elasticity and friction of the anti-slip silicone sleeve 608 allow the clamping part to adapt to brackets of different shapes and sizes, providing stable clamping force to firmly fix the bracket in the accurate position, completing positioning and clamping. After positioning and clamping are completed, activate four electric cylinders 602. The four electric cylinders 602 drive four hydraulic cylinders 605 and the corresponding first bracket 1 and second bracket 2 to move along a specific direction, causing the first bracket 1 and second bracket 2 to gradually approach and align. When the first bracket... After the first and second supports 1 and 2 are fully aligned, welding begins. The welding assembly 6 is quickly positioned, and four hydraulic cylinders 605 clamp and fix the first and second supports 1 and 2 in opposite directions. This allows for rapid positioning of the two supports 1 and 2 to be welded in accurate positions. Furthermore, the four electric cylinders 602 drive the four hydraulic cylinders 605 and the first and second supports 1 and 2 to move and align precisely, ensuring accurate welding position and improving welding quality and consistency. The uniform and stable clamping force provided by the four hydraulic cylinders 605 ensures that the supports will not shift or shake due to external forces or welding deformation during welding, thus guaranteeing the stability of the welding process and the quality of the weld. The coordinated work of the four electric cylinders 602 and four hydraulic cylinders 605 automates the positioning and clamping process of the first and second supports 1 and 2, reducing manual operation, lowering labor intensity, improving production efficiency, and minimizing quality instability caused by human error.
