Abstract
Description
Technical Field
[0001] This utility model belongs to the field of bucket welding technology, specifically relating to tooling fixtures with adjustable structures. Background Technology
[0002] Bucket welding fixtures are specialized clamps or positioning devices used for welding buckets (shovels) of construction machinery such as excavators and loaders. Their core function is to quickly position, clamp, and fix the various components of the bucket in preset positions through precise structural design, ensuring the relative positional accuracy between parts during the welding process, reducing welding deformation, and improving welding efficiency and product consistency.
[0003] Specifically, when using tooling fixtures to clamp and weld excavator buckets, the buckets are often several tons in weight due to their heavy steel plate construction. This excessive weight poses a significant challenge to the clamping operation. During clamping, multiple workers need to work together with lifting equipment to precisely align the bucket components to the tooling positioning points. This not only consumes a lot of manpower and time, but also makes it difficult to align the heavy components due to swaying when adjusted in mid-air. At the same time, the excessive weight puts continuous pressure on the positioning components of the tooling fixture. If the clamping force is insufficient, micro-displacement can easily occur under welding vibration or thermal stress, affecting the welding accuracy. Utility Model Content
[0004] The purpose of this utility model is to provide a tooling fixture with an adjustable structure, which aims to solve the problem that during the clamping process, multiple workers need to work together with the help of hoisting equipment to accurately align the bucket component to the tooling positioning point. This not only consumes a lot of manpower and time, but also makes it difficult to align the heavy component due to shaking when it is suspended in the air. At the same time, the excessive weight will put continuous pressure on the positioning components of the tooling fixture. If the clamping device has insufficient locking force, it is easy to have micro-displacement under the action of welding vibration or thermal stress, which will affect the welding accuracy.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a tooling fixture with an adjustable structure, including a base and a tilting housing mounted on the surface of the base. A control box is connected to one side of the tilting housing, a turntable is connected to the output end of a tilting motor inside the tilting housing, a lifting guide rail is connected to the other side of the turntable, a chain box is connected to the top of the lifting guide rail, a positioning plate is connected to one side of the lifting guide rail via a chain, a support frame is connected to one side of the positioning plate, and a clamping table is connected to the other end surface of the support frame. A fixing plate is connected to the surface of the clamping table. A driving cylinder is connected to one side of the fixing plate. A pressing plate is connected to the output end of the driving cylinder. A limit shaft is connected to the other side of the pressing plate. A threaded vertical plate is connected to the surface of the clamping table near the fixing plate. A lead screw is connected through the surface of the threaded vertical plate. A bearing block is connected to one end of the lead screw. A clamping plate is connected to the other side of the bearing block. A sliding plate is connected to the bottom end of one side of the clamping plate.
[0006] To facilitate the movement of the clamping plate, the tooling fixture with an adjustable structure of this utility model preferably has the limiting shaft engaged with the bucket pin hole, and the threaded vertical plate and the lead screw threadedly connected.
[0007] To facilitate the positioning and movement of the clamping plate, the tooling fixture with an adjustable structure of this utility model preferably has the lead screw rotatably connected to the inner lining of the bearing block, and the sliding plate passing through the threaded vertical plate and forming a sliding connection structure with the bottom opening of the threaded vertical plate.
[0008] To facilitate quick disassembly and assembly of the clamping platform, the tooling fixture with an adjustable structure of this utility model preferably has a disassembly block connected to the bottom surface of the clamping platform, and a positioning seat connected to the bottom surface of the support frame near the disassembly block. The openings on the surfaces of the disassembly block and the positioning seat correspond to each other to form a fitting structure.
[0009] To facilitate the assembly of the disassembly blocks, as a tooling fixture with an adjustable structure of this utility model, preferably, a slot is provided on one side of the disassembly block, a rotating shaft is connected to the inner wall of the opening on one side of the positioning seat, and a clamping plate is rotatably connected to the other end of the rotating shaft. The clamping plate and the slot on one side of the disassembly block form an interlocking structure.
[0010] To facilitate the fixing of the clamping plate, as a tooling fixture with an adjustable structure of this utility model, preferably, the other end of the clamping plate is connected to a linkage block, one end of the linkage block is connected to a stud, and the surface of the stud is threaded with a nut.
[0011] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a lifting device to place the bucket to be welded on the surface of a clamping platform. Then, a drive cylinder is activated, moving the extrusion plate and causing a limiting shaft to pass through the bucket pin hole, thus fixing one end of the bucket in place. Next, the lead screw on the threaded vertical plate is rotated, causing it to rotate along the inner lining of the bearing block and slide along the surface of the clamping platform. This facilitates the clamping plate clamping and fixing the other end of the bucket, preventing any shaking during bucket welding and improving the quality of the bucket welding.
