Description

Technical Field

[0001] This article belongs to the technical field of welding auxiliary equipment, specifically relating to a tooling fixture that facilitates welding. Background Technology

[0002] Welding equipment fixtures are used to accurately position and clamp parts for assembly and welding. In the production of welded structures, these two processes are usually completed in two ways depending on the process: one is to assemble first and then weld; the other is to assemble and weld simultaneously. We call the fixtures used for assembly and tack welding assembly fixtures; the fixtures specifically used for welding parts are called welding fixtures; and the fixtures used for both assembly and welding are called welding fixtures. They are collectively referred to as welding tooling fixtures.

[0003] Therefore, welding fixtures are crucial in the welding process, especially when the precision requirements of the welded workpieces are high. The use of fixtures is particularly critical. Through the coordination and fixation of fixtures, the accuracy of the weld can be ensured, thereby avoiding deviations and errors in the welding process. In addition, the application of fixtures can significantly improve production efficiency, improve the quality of welded products, and meet strict process standards.

[0004] The tooling fixtures used in current welding equipment lack positioning accuracy and dynamic compensation capability. Under the high temperature of welding, metal parts are prone to thermal expansion, which can lead to problems such as weld misalignment. Furthermore, the fixture design does not fully consider the accessibility of the welding torch, resulting in limited welding angles or repeated disassembly and assembly of workpieces, which affects welding quality and efficiency. Utility Model Content

[0005] To address the aforementioned issues, this paper proposes a welding-friendly tooling fixture. The tooling fixture includes a base, a fixture body base, and a fixture body. The base includes a base top plate, base side plates, a base bottom plate disc, and a base reinforcing plate. The fixture body base includes fixture body base side plates, fixture body base top plates, fixture body base front plates, and fixture body base baffle plates. The fixture body is bolted to the fixture body base. The fixture body includes an elastic chuck, bolt supports, and a double-column positioning structure.

[0006] The base top plate is horizontally set, and the four sides of the base top plate are vertically connected to the base side plates. The base bottom plate disc is fixed to the bottom of the base side plates through the base reinforcing plate. The base bottom plate disc is provided with bolt positioning holes along the edge of the disc. The base bottom plate disc is fixed to the welding platform by bolts to enhance the stability of the tooling fixture during operation.

[0007] The clamp body base side plate is vertically fixed to the base top plate. The upper part of the clamp body base side plate is provided with a square hole. The top of the clamp body base side plate is connected to the clamp body base top plate. The front plate of the clamp body is provided on the front and rear sides. The clamp body base top plate is fixed to the clamp body front plate through the clamp body base baffle iron plate. In the design of the clamp body base side plate, a square hole is specially provided on its upper part to facilitate the easy disassembly of the bolts between the clamp body and the clamp body base top plate. This design significantly simplifies the maintenance or adjustment process and improves work efficiency. In addition, the baffle iron plate equipped on the clamp body base enables the clamp to better resist external forces during use, ensuring the stability of clamping the workpiece, thereby improving the safety and durability of the entire clamp system.

[0008] The fixture body base has an elastic chuck at the front end, and a bolt support is provided on the protruding part of the top plate of the fixture body base above the baffle iron sheet. A double column positioning structure perpendicular to the top plate of the fixture body base is provided above the fixture body base. The elastic chuck, bolt support and the bottom plate of the double column positioning structure are all provided with bolt positioning holes to facilitate disassembly and fastening of the workpiece.

[0009] The elastic chuck includes a chuck plate, a chuck base plate, and a chuck pad. The elastic chuck is a replaceable structure, and the opening angle of the elastic chuck jaws is matched according to the size of the workpiece end.

[0010] The bolt support includes an adjusting bolt, a bolt support plate, and a bolt base plate. The adjusting bolt can be independently adjusted to adapt to the side of the workpiece with different widths for fastening. The upper end of the bolt support plate is provided with a hole through which the adjusting bolt passes. The bolt base plate is provided with a bolt positioning hole and is fixedly connected to the top plate of the fixture body base by bolts.

[0011] The dual-column positioning structure includes dual positioning columns, positioning side plates, positioning baffle plates, and a positioning base plate. Each of the dual positioning columns, positioning side plates, positioning baffle plates, and positioning base plate has bolt positioning holes. The dual positioning columns are vertically positioned on the positioning base plate. The positioning base plate is connected to the top plate of the fixture body base via the bolt positioning holes. The positioning side plates are fixed to the dual positioning columns with bolts. The positioning baffle plates are perpendicular to the positioning side plates and the positioning base plate. The dual-column positioning structure forms guide grooves with the positioning side plates, facilitating workpiece fixation. The dual-column positioning structure allows for quick disassembly and replacement of its components via bolts.

[0012] Beneficial effects:

[0013] The base plate adopts a disc-shaped design, and the bolt positioning holes evenly distributed on its edge allow the base to be tightly fixed to the welding platform through these holes, which significantly improves the stability of the tooling fixture during operation and thus effectively extends the service life of the tooling fixture.

[0014] Through the composite support structure formed by the base reinforcement plate, the side panels and top plate of the fixture body base, and the frame structure of the fixture body base, the overall vibration resistance and load-bearing capacity of the tooling fixture are greatly improved. During the welding process, the base, fixture body base and fixture body can maintain structural stability under various working conditions, thereby ensuring that the rigid fixation of the workpiece can effectively suppress the deformation caused by thermal stress. At the same time, this also avoids quality defects such as weld offset and overlap caused by workpiece displacement, and improves the consistency and pass rate of the welded products.

[0015] By using bolt positioning holes between the fixture body and its base, precise alignment between the two is achieved, ensuring accurate movement of the fixture body structure. Simultaneously, the precise coordination of symmetrical columns and a multi-hole adjustment mechanism ensures the functional independence and detachability of each component (including the base top plate, side plates, reinforcing plates; the fixture body base side panels, top plate, front plate, and baffle plates; elastic chucks, bolt supports, column positioning plates, etc.). This not only improves the adaptability of welded workpieces and meets diverse production needs but also significantly enhances the convenience of replacing or repairing local components, effectively reducing maintenance costs. Furthermore, this structural design ensures the stability and reliability of the tooling fixture, significantly improving positioning accuracy and operational convenience, further enhancing production efficiency and product quality.

[0016] By employing an elastic clamping mechanism with a flexible chuck, the chuck utilizes its excellent elastic properties to clamp the workpiece. This not only ensures a firm hold and prevents displacement during processing, but also flexibly adapts to minute dimensional differences between workpieces, effectively avoiding workpiece deformation and thus improving processing accuracy. Furthermore, the elastic clamping mechanism helps ensure accurate welding positions, allowing welding operations to be performed in a more stable and precise environment, significantly improving overall welding quality and work efficiency.

[0017] By employing a bolt adjustment mechanism that works in conjunction with an elastic chuck, the workpiece can be quickly clamped and disassembled. The combined design of the column positioning structure and the bolt adjustment mechanism greatly improves the welding accuracy of the workpiece. The workpiece position is determined by the joint action of the column positioning structure and the adjusting bolt, which can quickly fix the workpiece and avoid the process of manual marking or repeated calibration, thus significantly improving clamping efficiency. It is especially suitable for batch welding production scenarios. Attached Figure Description
