Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-2, a rotatable rocker arm drill workbench belongs to the technical field of machining, is simple and effective in structure, and can realize comprehensive machining of workpieces without dismounting, repositioning and mounting.
The utility model discloses a workstation is bored to rotatable rocking arm, including unable adjustment base 1 and swivel work head 2, T type groove 3 has been seted up to swivel work head 2's upper surface, and T type groove 3 is used for installing T type piece fixed work piece. The center position of the lower surface of the rotary table 2 is fixedly connected with a rotating shaft 4, and the rotating shaft 4 is used for ensuring that the rotary table 2 is not eccentric in the rotating process. The lower surface of the rotary worktable 2 is provided with an annular groove 5, the annular groove 5 is concentric with the rotating shaft 4, and the annular groove 5 limits the rotating route of the rotary worktable 2. Cylindrical through-hole 6 has been seted up to unable adjustment base 1's upper surface central point, and cylindrical through-hole 6 diameter is greater than the diameter of rotation axis 4 to ensure swivel work head 2 and rotation axis 4 at the rotation in-process, can not rub with cylindrical through-hole. The upper surface of unable adjustment base 1 is provided with hemispherical recess 7, and hemispherical recess 7 sets up along the circumference equipartition, and hemispherical recess 7 place circumference and annular groove 5 phase-match are used for placing rolling element 13. The middle of unable adjustment base 1 is hollow transmission layer 8, be provided with drive gear 9 in the transmission layer 8, drive gear 9 and rack 10 intermeshing, the one end of rack 10 and the cylinder end threaded connection of telescoping cylinder 11, the cylinder body of telescoping cylinder 11 is fixed in transmission layer 8 bottom, the flexible relative motion that drives rack 10 and drive gear 9 of telescoping cylinder 11, and then the drive passes rotation axis 4 of drive gear 9 pilot hole and rotates together, in this embodiment, use telescoping cylinder 11 to drive the transmission of rack and pinion during adoption, for reaching higher precision, in other embodiments, also can use servo motor to drive the transmission form of ball. Sunken step has been seted up to 8 bottom central points in drive layer, and the step internal fixation has bearing 12, and bearing 12 sets up with cylindrical through-hole 6 is concentric, and bearing 6 is used for restricting the free end of rotation axis 4 and does not take place the skew to prevent at rotatory in-process, the swivel work head 2 at top takes place the slope.
