In order to ensure maximum concentricity also in a balancing or measuring device having a small number of parts, the spring arrangement is designed to be integral with the centering element. | ||||||
| 104 | Fastener and method for fastening to associated structural assembly | US15214139 | 2016-07-19 | US09895750B2 | 2018-02-20 | Brent F. Craig; Patrick K. Dillon; Matthew K. Roberts |
| A fastener for fastening a drill jig to overlapping work pieces and clamping the overlapping work pieces for facilitating accurate drilling of the overlapping work pieces including a fastener body and a damper assembly operatively connected to the fastener body. The damper assembly is configured to enable application of a first load to the drill jig, and the fastener body is configured to enable application of a second load to the overlapping work pieces when the fastener fastens the drill jig to the overlapping work pieces. The first load is less than the second load. The first load is sufficient to hold the drill jig to the overlapping work pieces during drilling but without causing significant deformation of the drill jig. The second load is sufficient to reduce the formation of burrs during drilling of a hole through the overlapping working pieces. | ||||||

| The invention relates to a machine (1) for machining pipe ends. At least one centering device (8; 35) is associated to said machine, which centering device centers a tubular workpiece (5, 5′) in relation to an axis of rotation (D) of the machine for machining pipe ends extending in the center of the machine, the tubular workpiece either being stationary in the case of a rotating tool head (4) or rotating in the case in which the tubular workpiece is fastened in the machine chuck (9). Precise centering of the tubular workpiece (5, 5′) is quickly and simply achieved in that the centering device (8; 35) has a clamping housing (13; 130) that is open toward the axis of rotation (D), which clamping housing is designed comprising at least three means (14, 15, 16; 140, 150, 160) for contacting the tubular workpiece at the outer circumference and for clamping the tubular workpiece (5, 5′) in a centered manner, which means are circumferentially distributed and adjust mechanically independently of each other to the particular diameter of the workpiece (5, 5′) to be machined. | ||||||
