Problems solved by technology
[0005] 1) It belongs to manual destruction, the destruction strength is uneven, and it is easy to cause different degrees of damage to the bonding surface;
[0006] 2) The rubber layer cannot be removed 100%, and part of the bonding interface is not fully exposed, which affects the quality inspection personnel's judgment on the bonding surface;
[0007] 3) When destroying, it is necessary to manually remove the rubber point by point, which is time-consuming and labor-intensive

The invention provides a peeling device for a rubber piston cup and a method for detecting the adhesive quality of a rubber piston cup by using the device, which includes a lower plate and a peeling block, a fixed pin is arranged in the middle of the lower plate, and guide pins are respectively arranged on both sides of the fixed pin. Device, the middle part of the peeling block corresponds to the fixed pin to set a cavity for placing the rubber piston cup, the center of the cavity is located at the center of the fixed pin, the inner diameter of the cavity is smaller than the rubber outer diameter of the rubber piston cup, and larger than the metal of the rubber piston cup. On the outer diameter of the framework, a guide cavity is provided at the place corresponding to the guide device of the peeling block. The invention improves the consistency and comprehensiveness of the bonding quality detection between the existing single-lip and double-lip rubber piston cup rubber layers and metal skeletons used in aviation.
Description
technical field [0001] The invention belongs to the field of bonding quality inspection of rubber and metal bonded products, and in particular relates to a peeling device for a rubber piston cup and a method for detecting the bonding quality of a rubber piston cup by using the device. Background technique [0002] The rubber piston cup can transmit pressure and seal through the contact between the flexible rubber sealing lip and the shaft, and is an important part of the aero-engine. [0003] Rubber piston cups are mostly used in harsh environments, the linear velocity of the shaft diameter is ≥4m / s, there is no circulating oil, and the working oil temperature is ≥60°C. In continuous operation, high speed and operating environment require the rubber of the rubber piston cup. The bonding force between the layer and the metal skeleton must meet the requirements. When the bonding force does not meet the requirements, it is easy to cause the rubber and the metal skeleton to fal...
