Description

Technical Field

[0001] This utility model relates to the field of welding equipment technology, specifically a special material clamping mechanism for welding machines. Background Technology

[0002] The biggest advantage of handheld welding machines is their simple structure, quick learning curve, flexible welding, and strong welding penetration. They can handle welding at various complex angles. The models are available in mobile and stationary versions. When welding, the welder needs to hold the material to be welded with one hand and use the welding machine with the other hand. This welding method is relatively cumbersome and cannot effectively fix the material. It lacks effective support and fixation for square or round pipes.

[0003] Patent document CN201922326171.4 discloses a material clamping and welding device for a turning machine, relating to the field of turning machines. Addressing the problems of existing turning machines being unable to effectively perform semi-automatic fixing operations during material welding and being unable to handle welding fumes and slag, the following solution is proposed: It includes a base plate, with a base connected to the bottom end of the base plate. The base has a hollow structure. A mounting hole communicating with the base is provided in the middle of the base plate, and a mounting bracket is installed in the mounting hole. An air suction fan is mounted on the mounting bracket by screws. A horizontally arranged filter plate is installed at the mounting hole, and the filter plate is positioned above the air suction fan.

[0004] However, the aforementioned welding clamping devices can only align two pipes parallel to each other, not perpendicularly. The welding fixation method is limited. Since the pipes are cylindrical, they need to be rotated during welding to ensure a secure weld. The existing equipment requires disassembling and reinstalling the pipes for rotation, making simultaneous support and fixation impossible. Therefore, a dedicated material clamping mechanism for welding machines was designed. This mechanism effectively secures the pipes, forming a stable connection, while also allowing rotation for omnidirectional welding without the need for disassembly and re-fixation. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing welding clamping devices, which cannot align two pipes perpendicularly to each other, have a single welding and fixing method, require disassembling and reinstalling the pipes before welding, and cannot rotate while supporting and fixing.

[0006] This utility model is implemented as follows: a special material clamping mechanism for welding machines includes an operating table, on which a fixed bracket and a transverse moving device are provided. A transverse moving plate is slidably provided on the fixed bracket. The transverse moving device drives the transverse moving plate to move back and forth.

[0019] 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.

[0020] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0021] Traditional clamping devices often require multiple disassembly, reinstallation, and angle adjustments when facing different welding position requirements. This not only consumes a lot of time and manpower, but also easily leads to component wear and reduced positioning accuracy due to repeated operations.

[0022] This utility model provides a special material clamping mechanism for welding machines, which aims to achieve precise clamping and multi-angle adjustment of materials during welding operations, reduce the process of repeated fixing and disassembly, and improve the efficiency and quality of welding operations.

[0023] Example 1 like Figure 1-7 As shown, this utility model provides a special material clamping mechanism for welding machines, including an operating table 1. The operating table 1 is provided with a fixed bracket 11 and a transverse moving device 2. A transverse moving plate 3 is slidably arranged on the fixed bracket 11. The transverse moving device 2 drives the transverse moving plate 3 to move back and forth. A flipping device 4 is provided on one side of the transverse moving plate 3. A material clamping device 5 is provided at the front end of the flipping device 4. An angle fixing device 6 is also provided on the fixed bracket 11.

[0024] like Figures 1-2 As shown, the special material clamping mechanism for this welding machine mainly consists of an operating table 1, a fixed bracket 11, a transverse moving device 2, a transverse moving plate 3, a flipping device 4, a material clamping device 5, and an angle fixing device 6. The operating table 1 serves as the basic support platform for the entire mechanism. The fixed bracket 11 is vertically mounted on the operating table 1, providing track guidance support for the sliding of the transverse moving plate 3. The transverse moving device 2 is installed on the operating table 1 and is used to drive the transverse moving plate 3 to perform reciprocating linear motion. The flipping device 4 is located on one side of the transverse moving plate 3, realizing the flipping action of the material clamping device 5. The material clamping device 5 is installed at the front end of the flipping device 4 and is responsible for clamping the material to be welded. The angle fixing device 6 is located on the fixed bracket 11 and is used to fix the rotation angle of the material clamping device 5.

[0025] like Figures 3-4 As shown, the lateral movement device 2 includes a lateral drive motor 21 and a movable lead screw 22. The lateral drive motor 21 provides power for the entire lateral movement, and its output shaft is connected to the movable lead screw 22. A nut is provided on the movable lead screw 22, and a lateral movement connecting plate 23 is fixedly installed on the nut. The lateral movement connecting plate 23 and the lateral movement plate 3 are fixedly connected by bolts. When the lateral drive motor 21 starts, it drives the movable lead screw 22 to rotate through the output shaft. The rotational motion of the movable lead screw 22 is converted into the linear motion of the nut, which in turn drives the lateral movement plate 3 to reciprocate on the fixed bracket 11 through the lateral movement connecting plate 23.

[0026] The bottom of the transverse moving plate 3 is provided with multiple sliders 31, and the fixed bracket 11 is provided with a pair of parallel transverse slide rails 32. The sliders 31 slide and engage with the corresponding transverse slide rails 32, so that the transverse moving plate 3 can move linearly under the guidance of the transverse slide rails 32.

[0027] like Figure 4 As shown, multiple photoelectric displacement detection switches 12 are installed on the top of the fixed bracket 11, and a displacement photoelectric trigger plate 13 is installed on the transverse moving plate 3. When the transverse moving plate 3 moves under the drive of the transverse moving device 2, the displacement photoelectric trigger plate 13 moves along with the transverse moving plate 3. When the displacement photoelectric trigger plate 13 moves into the detection range of the photoelectric displacement detection switch 12, the photoelectric displacement detection switch 12 will send a signal, and the controller can obtain the real-time position of the transverse moving plate 3 and perform alignment correction. In this way, the moving position of the transverse moving plate 3 can be precisely controlled, and accurate positioning of the transverse movement can be achieved.

[0028] like Figures 2-3As shown, the flipping device 4 includes a flipping motor mounting plate 41 and a flipping base 42. A flipping motor 43 is fixedly mounted on the flipping motor mounting plate 41, and the rotating shaft 44 of the flipping motor 43 passes through the flipping base 42. A material clamping device 5 is located at the front end of the rotating shaft 44. When the flipping motor 43 is started, its rotating shaft 44 drives the material clamping device 5 to rotate around the rotating shaft 44, thereby realizing the flipping action of the material clamping device 5 and meeting the requirements of different welding angles.

[0029] like Figures 5-6 As shown, the material clamping device 5 includes a first material clamping plate 51 and a second material clamping plate 52 arranged in parallel. A connecting support rod 50 is provided between the first material clamping plate 51 and the second material clamping plate 52 to enhance structural stability. The first material clamping plate 51 is fixed on the rotating shaft 44, and a movable support device 7 is provided on one side of the second material clamping plate 52.

[0030] like Figures 1-2 As shown, the movable support device 7 includes a movable slide rail 71 and a movable support frame 72. A movable slider 73, which slides in cooperation with the movable slide rail 71, is provided at the bottom of the movable support frame 72. A rotating connector 74 is provided between the upper end of the movable support frame 72 and the second material clamping plate 52. This allows the second material clamping plate 52 to move and rotate synchronously with the first material clamping plate 51 under the support of the movable support device 7.

[0031] Both the first material clamping plate 51 and the second material clamping plate 52 are equipped with clamping drive cylinders 53 and material grippers 54, which are arranged symmetrically. Linear bearings 55 are installed between each clamping drive cylinder 53 and material gripper 54. The linear bearings 55 reduce the thrust between the clamping drive cylinders 53 and the material grippers 54, improving the smoothness and accuracy of the movement. The material grippers 54 are equipped with multiple limiting grooves 540, which are square in shape and mainly used for clamping square or round pipes. The limiting grooves 540 can better fix and position the material to be clamped, preventing the material from sliding or shifting during clamping.

[0032] like Figure 5 , Figure 7 As shown, the first material clamping plate 51 has multiple limiting holes 510 on the circumferential direction on the side near the fixed bracket 11. The angle fixing device 6 includes a fixed drive cylinder 61 and a fixed movable plate 62. The fixed movable plate 62 is fixed on the telescopic rod of the fixed drive cylinder 61, and a fixing pin 63 is provided on the fixed movable plate 62.

[0033] After the material clamping device 5 is adjusted to the required rotation angle by the flipping device 4, the fixed drive cylinder 61 is started, and its telescopic rod pushes the fixed movable plate 62 forward, so that the fixed clamping post 63 is engaged and fixed with one of the limiting holes 510 on the first material clamping plate 51, thereby realizing the angle fixation of the material clamping device 5 and ensuring the stability of the material during the welding process.

[0034] Working principle: The material to be welded is placed between the first material clamping plate 51 and the second material clamping plate 52. The clamping drive cylinder 53 is activated, which pushes the material gripper 54 to move towards the material, so that the limiting groove 540 on the material gripper 54 fits tightly with the material, thus clamping the material. Then, the transverse drive motor 21 is activated, which drives the transverse moving plate 3 to move laterally on the fixed bracket 11 through the movable lead screw 22 and the transverse moving connecting plate 23. At the same time, the photoelectric displacement detection switch 12 and the displacement photoelectric trigger 13 are used to precisely control the movement position of the transverse moving plate 3, so that the material reaches the designated position. The operator performs welding operations at the horizontal welding position. When it is necessary to adjust the welding angle of the material, the flipping motor 43 is started, which drives the material clamping device 5 to rotate through the rotating shaft 44, adjusting the material to the required welding angle. After the angle adjustment is completed, the fixed drive cylinder 61 is started, so that the fixed pin 63 is engaged and fixed with the corresponding limit hole 510 on the first material clamping plate 51, ensuring that the angle of the material remains unchanged during the welding process. After the above adjustment and fixing are completed, the welding operation can be carried out. After the welding is completed, the material clamping jaw 54 is released and the welded material is taken out according to the reverse operation process.

[0035] This invention, through the combination of a flipping device and an angle fixing device, can easily achieve the adjustment and fixing of pipes at various angles, meeting the welding requirements of various angles. The pipe is fixed by the locking of the fixing post and the limiting hole, ensuring stability during welding and improving welding quality. The flipping device eliminates the need for frequent disassembly of rotating parts during welding. The flipping device and the angle fixing device work together to accurately and quickly adjust the material to the required position and angle and fix it, greatly reducing non-welding operation time, effectively improving overall welding efficiency, and reducing cost losses caused by frequent disassembly and rotation.

[0036] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
