Description

Technical Field

[0001] This utility model relates to the technical field of welding stations for irregularly shaped parts, and in particular to a welding station for irregularly shaped parts. Background Technology

[0002] The irregular part assembly welding station is a high-efficiency and precise welding equipment that meets the needs of modern manufacturing for welding complex components. Irregular parts usually require customized production processes. Traditional welding methods may lead to high labor costs and process complexity. The irregular part assembly welding station helps to reduce costs and improve production efficiency by optimizing the production process. It is commonly used in the processing and production of mechanical parts.

[0003] Existing technologies, such as the utility model patent with publication number CN221455069U, disclose a positioning fixture for positioning irregularly shaped thin-walled parts. This patent includes a base plate, the main function of which is to install the positioning fixture as a whole onto the processing equipment. By installing a placement platform on the top of the base plate, the irregularly shaped thin-walled parts to be processed can be placed on the top of the placement platform for support, and the placement platform allows the irregularly shaped thin-walled parts to be processed to be moved. By welding long positioning blocks on both sides of the top of the base plate, the long positioning blocks can position both sides of the irregularly shaped thin-walled parts, fixing one end of the irregularly shaped thin-walled parts. Then, by welding short positioning blocks on both sides of the other side of the top of the base plate, the short positioning blocks can position both sides of the other end of the irregularly shaped thin-walled parts, fixing the other end of the irregularly shaped thin-walled parts. This prevents the irregularly shaped thin-walled parts from deforming due to vibrations during processing, thereby improving production efficiency.

[0004] During the processing and production of mechanical parts, it has been found that there are many different types of irregularly shaped parts. Due to the irregular geometry, deviation of the center of gravity, lack of stable reference surface, insufficient rigidity or easy deformation of irregularly shaped parts, and the fact that most clamping and positioning mechanisms have relatively simple fixed dimensions, it will be inconvenient to clamp and limit the irregularly shaped parts. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that in the processing of mechanical parts, there are many different kinds of irregular parts. Due to the irregular geometry, deviation of the center of gravity, lack of stable reference surface, insufficient rigidity or easy deformation of irregular parts, and the fact that most clamping and positioning mechanisms have relatively simple fixed dimensions, it is inconvenient to clamp and limit the irregular parts.

[0006] To solve the above-mentioned technical problems, this utility model provides a welding station for irregularly shaped parts, comprising: an operating table, with base plates fixedly connected to both sides of the lower surface of the operating table, and a support frame fixedly connected to the upper surface of the operating table. The support frame has a U-shaped cross-section, and an adjustment device is provided on the surface of the support frame. The adjustment device includes two adjustment rods, the lower surfaces of the two adjustment rods being fixedly connected to the two side surfaces of the support frame, and movable frames being slidably connected to the two end surfaces of the two adjustment rods. The upper ends of the two movable frames are fixedly connected to the same limiting position. The frame has an L-shaped cross-section. A pressing shaft is threaded through the inner wall surface of the movable frame. One end of the pressing shaft abuts against the surface of the adjusting rod. An adjusting shaft is threaded through the surface of the limiting frame. A movable plate is rotatably connected to the ends of the two adjusting shafts that are close to each other. Several telescopic rods are fixedly connected to the surface of the movable plate. Springs are slidably connected to the inner wall of the telescopic rod. The two ends of the springs are fixedly connected to the inner wall of the movable end of the telescopic rod and the surface of the movable plate, respectively. A positioning groove is formed on the surface of the limiting frame. The positioning groove is a multi-level groove.

[0007] The effects achieved by the above components are as follows: the movable frames on the two adjusting rods can slide independently, allowing the upper limiting frame to move in two dimensions in the horizontal plane, adapting to irregular parts of different sizes and shapes. By tightening the extrusion shaft, the movable frame can be quickly locked in any position on the adjusting rod, fixing the limiting frame. At the same time, rotating the adjusting shaft pushes the movable plate, thereby applying pressure to the workpiece through the floating clamping mechanism composed of telescopic rods and springs. The springs can compensate for the unevenness of the workpiece surface, providing a flexible and uniform clamping force, preventing rigid over-clamping from causing workpiece deformation or damage.

[0008] Preferably, guide rods are slidably passed through both ends of the limiting frame, and one end of the guide rod is fixedly connected to the surface of the moving plate.

[0009] The effect achieved by the above components is as follows: by sliding the moving plate and the limiting frame through the guide rod, it is ensured that the moving plate can only move in a straight line under the push of the adjusting shaft, and will not rotate or wobble, thereby ensuring the accuracy and stability of the clamping force and improving the reliability of clamping.

[0010] Preferably, a compression pad, which is a rubber pad, is fixedly connected to the moving end surface of the telescopic rod.

[0011] The effects achieved by the above components are as follows: the rubber extrusion pad increases the friction with the surface of the irregular part, effectively preventing the workpiece from sliding or shifting during the welding process; the softness of the rubber can prevent the hard metal telescopic rod from directly contacting and scratching the finished surface of the workpiece.

[0012] Preferably, a through hole is provided on one side surface of the movable frame, and a scale is provided on the surface of the adjusting rod, with the position of the through hole corresponding to the position of the scale.

[0013] The effect achieved by the above components is that the operator can observe the scale on the adjusting rod through the through hole, accurately control the distance between the two moving frames and the symmetrical center position of the limiting frame, achieve high-precision positioning and repeatable positioning, and ensure the consistency of batch welding.

[0014] Preferably, the surface of the operating table is provided with an auxiliary device, the auxiliary device including a slide rail, the lower surface of the slide rail being fixedly connected to the surface of the operating table, a support frame being slidably connected to the surface of the slide rail, the lower surface of the support frame being slidably connected to the surface of the operating table, connecting plates being fixedly connected to both sides of the support frame, a connecting bracket being fixedly connected to the side wall surface of the operating table at a position corresponding to the connecting plate, a rotating frame being rotatably connected to the inner wall of the connecting bracket, the upper inner wall of the rotating frame being inserted into the surface of the connecting plate, a connecting rod being threaded through the upper surface of the rotating frame, the arc surface of the connecting rod being slidably connected to the surface of the connecting plate, and a pull rod being fixedly connected to the surface of the support frame.

[0015] The above components achieve the following effects: the support frame can slide along the slide rail, making it convenient to transport the parts to be welded or small tools to the operating position or remove them. By lowering the rotating frame to make it plug into the connecting plate and locking it with the connecting rod, the support frame can be reliably fixed in a horizontal position, forming a stable auxiliary workbench or material tray.

[0016] Preferably, a coil spring is fitted onto the inner arc surface of one end of the connecting frame, and the two ends of the coil spring are fixedly connected to the connecting frame and the rotating frame, respectively.

[0017] The effect achieved by the above components is that the torque of the coil spring causes the rotating frame to have an automatic return tendency. When the connecting rod is released, the rotating frame will automatically spring upward under the action of the coil spring and disengage from the connecting plate, thus eliminating the need to manually turn the rotating frame.

[0018] Preferably, a magnetic frame is fixedly connected to the inner wall surface of the support frame, and the cross-sectional dimensions of the magnetic frame are adapted to the cross-sectional dimensions of the inner wall of the support frame.

[0019] The effects achieved by the above components are as follows: the magnetic frame can use magnetic force to attract iron welding parts and small tools, preventing them from sliding or tipping over in the support frame, keeping them neat and orderly. At the same time, iron debris and sparks generated during welding will be attracted to the magnetic frame instead of being scattered on the workbench or the ground. Only the magnetic frame needs to be cleaned, which greatly reduces the burden of cleaning work.

[0020] Compared with related technologies, the shaped component assembly welding station provided by this utility model has the following beneficial effects:

[0021] By operating the adjustment device, a fast, flexible, and adaptable multi-directional clamping effect is achieved for irregularly shaped parts. Operators can easily move and lock the position of the limit frame in the horizontal plane, and apply uniform clamping force to the workpiece through the telescopic pressure rod with spring buffer. This effectively overcomes the problems of clamping difficulties, easy deformation, and poor positioning accuracy caused by the irregular shape of irregularly shaped parts and the lack of a stable reference surface in traditional welding fixtures, and significantly improves the preparation efficiency and clamping reliability before welding.

[0022] By operating the auxiliary device, convenient support and efficient work environment management for welding operations are achieved. The support frame can be easily pulled out to serve as a material tray or auxiliary workbench. Its built-in magnetic frame effectively attracts and fixes ferrous workpieces and tools, and collects welding debris, keeping the work area clean and orderly. This device is integrated into the operating table, saving space and simplifying operation, greatly improving the continuity and safety of welding operations. Attached Figure Description

[0033] In the embodiments of this utility model, please refer to Figure 4 and Figure 5The auxiliary device 5 includes a slide rail 54, the lower surface of which is fixedly connected to the surface of the operating table 1. A bearing frame 51 is slidably connected to the surface of the slide rail 54. The lower surface of the bearing frame 51 is slidably connected to the surface of the operating table 1. Connecting plates 58 are fixedly connected to both sides of the bearing frame 51. A connecting frame 55 is fixedly connected to the side wall of the operating table 1 at the position corresponding to the connecting plate 58. A rotating frame 57 is rotatably connected to the inner wall of the connecting frame 55. The upper inner wall of the rotating frame 57 is inserted into the surface of the connecting plate 58. A connecting rod 59 is threaded through the upper surface of the rotating frame 57. The arc surface of the connecting rod 59 is slidably connected to the surface of the connecting plate 58. A pull rod 53 is fixedly connected to the surface of the bearing frame 51. A coil spring 56 is sleeved on the arc surface of the inner wall of one end of the connecting frame 55. The two ends of the coil spring 56 are fixedly connected to the connecting frame 55 and the rotating frame 57, respectively. A magnetic frame 52 is fixedly connected to the inner wall surface of the bearing frame 51. The cross-sectional dimensions of the magnetic frame 52 are adapted to the cross-sectional dimensions of the inner wall of the bearing frame 51.

[0034] The working principle of the irregular part assembly welding station provided by this utility model is as follows: First, the operator, based on the approximate size of the irregular part and the required clamping position, loosens the extrusion shafts 410 on the four moving frames 403. At this time, the moving frames 403 can slide freely on the adjusting rods 401. The two adjusting rods 401 are parallel to each other, forming a horizontal XY coordinate system. By sliding the moving frames 403, the entire upper "L"-shaped limiting frame 405 can move two-dimensionally in the horizontal plane to the desired approximate area. During this process, the operator can observe the scale 402 on the adjusting rods 401 through the through hole 404 on the moving frames 403, achieving precise and quantifiable positioning and ensuring consistency in repeated operations. After the limiting frame 405 is approximately positioned, the extrusion shafts 410 are tightened, so that their ends tightly abut against the surface of the adjusting rods 401. Friction is used to completely lock the moving frames 403 and the limiting frame 405 in this position. Subsequently… The operator rotates the adjusting shaft 408, and the inner end of the adjusting shaft 408 pushes the moving plate 407 to move along the guide rod 409 toward the workpiece. The pressing pads 412 at the ends of the multiple telescopic rods 411 on the moving plate 407 then contact the workpiece surface. As the adjusting shaft 408 continues to rotate, the moving ends of the telescopic rods 411 begin to compress the internal springs 413. The compression of the springs 413 generates a continuous reaction force, which is evenly applied to the workpiece through the pressing pads 412. Even if the contact surface of the workpiece is uneven, each telescopic rod 411 can extend and retract independently, adapting to the workpiece contour by different compression amounts, ensuring that the clamping force is evenly distributed and preventing the workpiece from warping or deforming.

[0035] The operator holds the lever 53 and pulls the support frame 51 out from the slide rail 54 under the operating table 1 to adjust the position of the support frame 51. The operator collects and cleans up any parts and welding slag that fall into the support frame 51. When the support frame 51 is pulled to the appropriate position, the operator flips the rotating frame 57 downward so that its upper inner wall is inserted into the connecting plate 58. Then, the operator screws in the connecting rod 59, which passes through the connecting plate 58 and locks the rotating frame 57, so that the support frame 51 is reliably supported in a horizontal position, forming a stable platform. The magnetic frame 52 inside generates magnetic force, which automatically attracts small iron parts or tools, preventing them from sliding or falling. At the same time, iron debris and sparks generated during welding are also attracted to the magnetic frame 52 instead of being scattered all over the ground, making it easy to collect and clean up. After use, the operator loosens and removes the connecting rod 59. Due to the preload of the coil spring 56, the rotating frame 57 will automatically spring back upward and disengage from the connecting plate 58.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
