Description

Technical Field

[0001] The invention belongs to the technical field of clutch accessory processing, and in particular relates to an intelligent leakage prevention device for a clutch accessory laser spot welding fixture. Background Art

[0002] In the manufacturing process of clutch parts, laser spot welding technology is widely used in the welding of various parts due to its advantages of high precision, high efficiency and low energy consumption. However, in practical applications, traditional laser spot welding fixtures still have some problems that need to be solved, especially the clamping stability and the leakage of the clamping surface during welding. These problems not only affect the welding quality, but also may pose a potential threat to the safety of the operation.

[0003] First, clamping stability is a key factor in laser spot welding operations. Clutch parts often have complex shapes and sizes. Traditional fixture designs often have difficulty in achieving stable clamping of various parts, which causes the parts to easily move or shake during welding, thus affecting welding accuracy and weld quality. In addition, uneven or excessive clamping force of the fixture may also damage the parts and reduce the product qualification rate.

[0004] Secondly, due to the differences in materials, structures and welding processes of clutch accessories, traditional clamps often find it difficult to form an effective sealing structure during the welding process. Thermal expansion or vibration during welding can easily lead to seal failure, and they cannot adapt to the sealing requirements of complex curved workpieces, causing gas or slag to leak from the clamping surface during welding. This not only affects the cleanliness of the welding environment, but may also have an adverse effect on the welding quality. Summary of the invention

[0081] In this embodiment, the servo motor 20 starts and transmits the power to the clamping plate 7 through the elastic coupling, driving the clamping plate 7 to rotate to adapt to the clamping and welding requirements of clutch accessories of different shapes and sizes. At the same time, due to the elastic deformation ability of the elastic coupling, it can absorb and alleviate the vibration or impact that may be generated during the clamping process, thereby protecting the servo motor 20 and the clamping plate 7 from damage.

[0082] In a further preferred embodiment of the present invention, Figure 7 As shown, a group of hydraulic cylinders 21 with axes perpendicular to the horizontal plane are symmetrically distributed on both sides of the two fixing frames 6, and connecting plates 22 are extended outward on both sides of the fixing frames 6. The ends of the piston rods of the two hydraulic cylinders 21 are connected to the connecting plates 22 through universal ball hinges.

The design of the micro-through hole array enables them to sensitively capture the deformation of the film and convert this deformation into an electrical signal to transmit to the external control system.
