Description

Technical Field

[0001] The present invention relates to the technical field of rubber ring crack detection equipment, and more particularly to a rubber ring invisible crack detection machine. Background Art

[0002] A rubber seal is an annular cover consisting of one or more parts. It is fixed to one bearing ring or washer and contacts or forms a narrow labyrinth gap with the other ring or washer to prevent lubricant leakage and foreign objects from entering. The most commonly used rubber ring is the "O"-shaped rubber ring. In order to ensure product quality, rubber rings must be inspected for possible cracks during the production process to ensure the product's sealing effect. Existing rubber ring crack detection devices, such as the rubber ring invisible crack detection device disclosed in Publication No. CN220323139U, include a device in which a rubber ring is sleeved on both sides of two limit rods by providing a limit rod. Under the action of a screw hole block and a slide groove, when the screw hole block slides on the inner wall of the slide groove, it can drive the limit rod to move on the top of the light-transmitting plate, thereby facilitating adjustment of the position between the two limit rods according to the actual size of the rubber ring. When the two limit rods stretch the rubber ring, the rubber ring can be effectively limited, thereby facilitating effective limitation of rubber rings of various models, thereby effectively improving the practicality of the device. However, existing crack detection devices cannot be adapted to the production line during use, and the entire detection process must be performed manually, which greatly reduces the detection efficiency of rubber rings and increases costs, making it unable to meet the large-scale production needs of factories.

The irregularly placed rubber rings can be formed into a fixed moving trajectory through the guide groove. When the rubber ring approaches the infrared sensor, the downward pressure device can be driven to drive the ring expansion device downward by outputting an electrical signal to the outside, so that the lower end of the ring expansion rod enters the inside of the rubber ring to be inspected, and then the ring expansion rod can move outward to expand the deformation of the rubber ring, making the cracks on it easier to be observed by the camera.

[0013] 2. An expanding rod is installed at the lower end of the expanding ring device, and rolling balls are installed at the upper and lower ends of the expanding ring rod. Six expanding rods are equidistantly arranged on the circumference of the expanding ring device, and the upper end of the expanding ring rod extends into the expanding ring device. A movable sleeve is installed on the outside of the middle end of the expanding ring rod. A movable slot is provided on the outside of the position of the movable sleeve corresponding to the inside of the expanding ring device. The movable slot is long and extends from the center to the edge along the radius of the expanding ring device. A reset spring is provided on the inside of the movable slot, so that the expanding ring can move upward in the movable sleeve, and the movable sleeve can drive the expanding ring to expand outward along the movable slot. Then, a middle support rod is provided at the middle end of the internal part of the expanding ring device, and an axis bracket is provided on the outside of the middle support rod. Six axis brackets are equidistantly arranged on the outside of the middle support rod. A rotating rod is installed on the inside of the axis bracket.
