Description

Technical Field

[0001] The present invention relates to the technical field of welding tooling, and in particular to an intelligent welding fixture with an anti-loosening function. Background Art

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

[0003] The existing publication number is: CN214161894U. This utility model relates to the technical field of welding tooling, specifically a fully automatic air-cooled plasma automatic welding tooling, comprising a base plate, a support block is provided on the upper end surface of the base plate, a connecting block is provided on the support block, an arc-shaped gasket is provided on the connecting block, a pipe is 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, a connecting head is provided on the first support frame, a third support frame is provided on the other side of the second support frame, a slot is provided on the third support frame, a fourth support frame is provided on the upper end surface of the base plate, a second clamping mechanism is provided on the fourth support frame, and a first clamping mechanism is provided on the front side of the support block.

[0004] However, when fixing the workpiece, the workpiece is generally positioned by a positioning block. After the workpiece is positioned, a pneumatic clamp is used to clamp the workpiece. However, since the positioning block is mostly a fixed structure, the contact position between the positioning block and the workpiece is fixed.

[0016] Beneficial effects

[0017] The present invention arranges a welding clamping mechanism. When plasma arc welding is performed on a workpiece, the workpiece is first placed above the welding platform so that the outer side of the workpiece contacts the welding positioning piece. The welding positioning piece realizes the positioning of the workpiece. The welding clamping cylinder is opened. The piston rod of the welding clamping cylinder moves forward to drive the welding clamping piece to move forward. The forward movement of the welding clamping piece drives the pressure sensor to move forward. The pressure sensor moves forward to squeeze the workpiece. Under the squeezing of the pressure sensor and the welding limit piece, the workpiece is clamped. The clamping cylinder is opened to clamp the workpiece. The auxiliary fixing fan is opened to generate negative pressure suction. The bottom of the workpiece is adsorbed by the auxiliary fixing plate, thereby increasing the fixing area of ​​the workpiece and improving the stability during welding of the workpiece.

[0018] The present invention realizes the detection of clamping pressure by setting the welding clamping mechanism during the welding process of the workpiece by the pressure sensor. The pressure sensor transmits the detection data to the PLC controller, and the controller controls the welding clamping cylinder. The welding clamping cylinder keeps the clamping force constant to avoid the displacement of the workpiece caused by pressure fluctuation. When the welding of a group of workpieces is completed, the detection drive cylinder is turned on, and the piston rod of the detection drive cylinder moves upward to drive the detection lifting slide block to move upward. The upward movement of the detection lifting slide block drives the detection drive slide block to move upward. While the detection drive slide block moves upward, it moves forward under the limit of the detection limit groove. At this time, The detection drive slider carries the laser displacement sensor to the front of the welding limiter. The laser displacement sensor detects the surface flatness of the welding limiter. Once the laser displacement sensor detects that the flatness of the welding limiter exceeds the threshold, the laser displacement sensor controls the external sound and light alarm to sound an alarm, thereby reminding the workers and realizing real-time monitoring of the wear or deformation of key parts of the tooling, avoiding welding errors caused by the decrease in positioning surface accuracy, ensuring the stability and accuracy of workpiece fixation during the welding process, and realizing preventive maintenance of the tooling status through automated detection, providing reliable process support for high-quality plasma arc welding.

[0019] The present invention arranges the welding clamping mechanism and the positioning rotation mechanism so that the positioning contact block contacts the workpiece. At this time, the positioning contact block realizes the positioning of the workpiece. When the workpiece is clamped, the welding clamping member moves forward to drive the rotation drive rack to move forward, the rotation drive rack moves forward to drive the rotation drive gear to rotate, the rotation of the rotation drive gear drives the rotation transmission ratchet to rotate, at this time the ratchet and the pawl of the rotation transmission ratchet are in a separated state, and when the workpiece is processed, the rotation drive rack moves backward to drive the rotation drive gear to rotate, the rotation of the rotation drive gear drives the rotation transmission ratchet to rotate, the rotation of the rotation transmission ratchet drives the rotation drive worm to rotate, the rotation of the rotation drive worm drives the rotation drive worm wheel to rotate, and the rotation of the rotation drive worm wheel drives the rotation drive disk to rotate 180 degrees. The rotation of the rotation drive disk drives the rotation drive part to rotate, and the rotation of the rotation drive part drives the rotation drive slider to move upward. The upward movement of the rotation drive slider drives the welding positioning part to move upward, and the upward movement of the welding positioning part drives the positioning contact block to move upward, thereby realizing the rotation of the positioning contact block, avoiding a single positioning contact block from being in contact with the workpiece for a long time, and extending the service life of the positioning contact block. At the same time, it ensures that the contact block fits the workpiece with an unworn working surface during each positioning, maintaining the stability of the positioning accuracy, and cleverly utilizing the energy transfer of the tooling clamping action to achieve rotation without the need for an additional power source. While improving the durability of the tooling, it also takes into account the economy and rationality of the mechanism design, providing a guarantee for the long-term and reliable operation of the positioning components in high-frequency welding processing.
