Description

Technical Field

[0001] This invention relates to the field of welding fixture technology, and in particular to an intelligent welding fixture with anti-loosening function. Background Technology

[0002] Plasma arc welding is widely used for precision welding of materials such as stainless steel and aluminum-magnesium alloys due to its advantages of concentrated energy and small heat-affected zone. However, the high-temperature heat input during welding can easily cause workpiece displacement or deformation, thus placing high demands on the positioning accuracy, clamping stability, and thermal adaptability of the fixing fixture. Traditional fixing methods mostly rely on mechanical positioning and rigid clamping. Typical structures include positioning pins, V-blocks, pressure plates, and clamping cylinders. The positioning mechanism uses high-precision machined positioning pins or slots to cooperate with the workpiece reference surface to achieve circumferential or axial limitation, ensuring that the weld position is accurately aligned with the welding torch trajectory. The clamping mechanism uses pneumatically or hydraulically driven pressure plates and jaws to apply uniform pressure to the workpiece and prevent loosening caused by welding vibration.

[0003] The existing publication number is CN214161894U. This utility model relates to the field of welding fixture technology, specifically a fully automatic air-cooled plasma welding fixture. It includes a base plate, a support block on the upper surface of the base plate, a connecting block on the support block, an arc-shaped gasket on the connecting block, and a pipe placed on the arc-shaped gasket. A support rod is provided on the upper part of a second support frame. A first support frame is provided on one side of the second support frame, and a connector is provided on the first support frame. A third support frame is provided on the other side of the second support frame, and a slot is provided on the third support frame. A fourth support frame is provided on the upper surface of the base plate, and a second clamping mechanism is provided on the fourth support frame. A first clamping mechanism is provided on the front side of the support block. This utility model, with its first and second clamping mechanisms, can clamp and fix the pipe, preventing it from moving and shaking during welding, thus improving welding efficiency and stability. Furthermore, the mechanical linkage mechanism makes operation more convenient.

[0004] However, existing methods for fixing workpieces typically involve using positioning blocks to position the workpiece, followed by clamping it with a pneumatic clamp. However, since positioning blocks are mostly fixed structures, the contact position between the positioning block and the workpiece is fixed. Over time, wear between the positioning block and the workpiece can easily affect the positioning accuracy of the positioning block. Summary of the Invention

Beneficial effects

[0016] This invention, through the design of a welding clamping mechanism, allows for the following steps during plasma arc welding: First, the workpiece is placed above the welding platform, ensuring its outer side contacts the welding positioning component. The welding positioning component positions the workpiece. Then, the welding clamping cylinder is activated, causing its piston rod to move forward, which in turn moves the welding clamping component forward. This forward movement of the welding clamping component, in turn, moves the pressure sensor forward, which presses against the workpiece. Under the pressure of the pressure sensor and the welding limiting component, the workpiece is clamped. Next, the clamping cylinder is activated, pressing the workpiece firmly. Finally, the auxiliary fixing fan is activated, generating negative pressure suction. This suction, through the auxiliary fixing plate, adheres to the bottom of the workpiece, increasing the fixing area and improving stability during welding.

[0017] This invention utilizes a welding clamping mechanism. During the welding process, a pressure sensor detects the clamping pressure, transmitting the data to a PLC controller. The controller then controls the welding clamping cylinder to maintain a constant clamping force, preventing workpiece displacement due to pressure fluctuations. After welding a set of workpieces, the detection drive cylinder is activated. The piston rod of the detection drive cylinder moves upward, causing the detection lifting slider to move upward. This upward movement of the detection lifting slider, in turn, causes the detection drive slider to move upward. Simultaneously, the detection drive slider moves forward under the constraint of the detection limit groove. The detection drive slider carries the laser displacement sensor to the front of the welding limit component. The laser displacement sensor detects the surface flatness of the welding limit component. Once the laser displacement sensor detects that the flatness of the welding limit component exceeds the threshold, it controls an external audible and visual alarm to sound an alarm, thus reminding the worker and enabling real-time monitoring of wear or deformation of key components of the tooling. This avoids welding errors caused by a decrease in positioning surface accuracy, ensuring the stability and accuracy of workpiece fixation during welding, and also enabling preventive maintenance of the tooling status through automated detection, providing reliable process support for high-quality plasma arc welding.

[0018] This invention utilizes a welding clamping mechanism and a positioning rotating mechanism. The positioning contact block contacts the workpiece, thus positioning it. When the workpiece is clamped, the welding clamping component moves forward, causing the rotating drive rack to move forward. This forward movement of the rotating drive rack rotates the rotating drive gear, which in turn rotates the rotating transmission ratchet. At this time, the ratchet and pawl of the rotating transmission ratchet are separated. After the workpiece is processed, the rotating drive rack moves backward, causing the rotating drive gear to rotate. This rotation of the rotating drive gear rotates the rotating transmission ratchet, which in turn rotates the rotating drive worm gear. This rotation of the rotating drive worm gear rotates the rotating drive worm wheel, which in turn rotates the rotating drive disk 180°. The rotating drive disc drives the rotating drive component to rotate, which in turn drives the rotating drive slider to move upward. This upward movement of the rotating drive slider then drives the welding positioning component to move upward, which in turn drives the positioning contact block to move upward. This achieves the rotation of the positioning contact block, avoiding prolonged contact between a single positioning contact block and the workpiece, thus extending the service life of the positioning contact block. Simultaneously, it ensures that the contact block is in contact with the workpiece with its unworn working surface during each positioning, maintaining the stability of positioning accuracy. This ingenious use of the energy transfer from the tooling clamping action to achieve rotation eliminates the need for an additional power source. While improving the durability of the tooling, it also considers the economy and rationality of the mechanism design, providing a guarantee for the long-term reliable operation of positioning components in high-frequency welding processes.
