A device for forming a groove in a cover, the device including a circular score anvil having a first axis and being rotatable in a first direction and a circular scoring knife having a second axis positioned parallel to the first axis and arranged radially opposite the circular score anvil to define a gap between the score anvil and the scoring knife. The scoring knife is rotatable in a second direction opposite to the first direction and comprises a scoring element having an edge region that is tapered to form a ridge toward a periphery of the element. The edge region includes an intermediate space that divides the edge region into two spaced apart knife edges. A groove is formed in the cover while moving through the gap by operative cooperation of the scoring knife and score anvil.

The invention discloses a floating elliptical ultrasonic vibration micro-engraving device, which comprises a mounting table (11), a support unit, a drive unit (2), a sliding unit (3), a floating transducing component (4), a longitudinal bending transducing device (1); support base (12), A support (13), B support (14) constitute a support unit; the lower mounting surface of the mounting table (11) is connected with support base (12), A support (13) respectively, The upper mounting surface (11a) of the mounting table (11) is connected with the numerical control workbench. Driven by the ultrasonic transducer, the cutting tool of the engraving device of the present invention can generate elliptical ultrasonic vibrations to realize micro-engraving. The micro-engraving device of the present invention uses the floating transducer assembly to ensure that the depth of the processed groove remains constant; and then uses the longitudinal bending transducer to make the tool generate ultrasonic elliptical vibration, and cutting with the help of ultrasonic elliptical vibration can reduce cutting force, improve processing accuracy and reduce The characteristics of surface roughness to ensure that the groove on the surface of the machined part has high geometric accuracy and surface quality and the edge is free of burrs; the combined design of the longitudinal bending transducer and the drive unit makes up for the inability of the tool in traditional planing The defect of rotation realizes freely adjustable engraving in multiple cutting directions.

The invention relates to the technical field of antenna vibrator processing, in particular to a drilling device for antenna vibrator processing, including a base and a fixing frame, the top of the base is fixedly connected with a fixing frame, and the right end of the fixing frame is fixedly connected with a controller. The inner side of the top end of the fixed frame is fixedly connected with a position adjustment device, the bottom end of the position adjustment device is fixedly connected with a drilling device, and the top end of the base is fixedly connected with a clamping device. , clamping rod, and connecting block, the clamping and fixing of the circular antenna vibrator can be realized through the first clamping plate, so as to ensure that the circular antenna vibrator will not shake when drilling, and ensure that there will be no vibration during the drilling process. In case of skewing, the loop antenna vibrator can be clamped and fixed by the second clamping plate, and at the same time, the ring antenna vibrator can be supported by the support column to prevent the inner wall of the loop antenna vibrator from being sunken during the drilling process.

The invention discloses a flower growing device with an automatic lifting water absorption apparatus and relates to a flowerpot. Ordinary flowerpots do not have a water storage function, flowers are needed to be watered every day, and dryness can be easily caused without day's watering. The flower growing device comprises a flowerpot body and an automatic lifting water absorption unit arranged in the flowerpot body. A partition layer is arranged in the flowerpot body and divides the flowerpot body into an upper layer and a lower layer. The automatic lifting water suction unit comprises a water suction disc, a water storage disc below the water suction disc and an elastic element below the water storage disc. The elastic element supports the water storage disc, and the compression amount of the elastic element is changed along with the water amount of the water storage disc. The water suction disc is disposed on the partition layer, a water suction hole is formed in the partition layer, a water suction column matched with the water suction hole is arranged on the water suction disc, and the height of the water suction column is larger than the thickness of the partition layer, so that the lower end of the water suction column can stretch out of the lower surface of the partition layer. A water injection hole is formed in the flowerpot body. By means of the device, the water storage disc is changed up and down along with the amount of storage water, and the water suction amount of the water suction disc is identical; plants can grow healthily by the fixed water suction amount.
