Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in figures 1-4, the 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 circular shape swivel work head 2, adopt circular shape swivel work head 2 can ensure that the size is the same all around at rotatory in-process, if adopt square workstation, then have convex corner at rotatory in-process, lead to scraping easily and bump with interfering. The upper surface of the rotary worktable 2 is provided with a T-shaped groove 3, and the T-shaped groove 3 is used for installing a T-shaped block to fix a workpiece. The center position of the lower surface of the rotary worktable 2 is fixedly connected with a rotating shaft 4, and the rotating shaft 4 is used for ensuring that the rotary worktable 2 does not generate eccentricity in the rotating process. The lower surface of the rotary worktable 2 is provided with a rectangular limiting strip 5 along the radius direction, and the limiting strip 5 is matched with a limiting groove 8 so as to limit the rotary worktable 2 and prevent the worktable from generating deviation rotation in the machining process and influencing the machining precision. The limiting strips 5 are uniformly distributed along the circumferential direction, can fall into the limiting groove 8 after rotating at any angle due to uniform distribution, and can only correspondingly fall into the limiting groove 8 within a limited angle range if not uniformly distributed. The center of the upper surface of the fixed base 1 is provided with a cylindrical through hole 6, and the cylindrical through hole 6 is used for penetrating through the rotating shaft 4. Cylindrical recess 7 has been seted up to unable adjustment base 1's upper surface, and cylindrical recess 7 sets up with cylindrical through-hole 6 is concentric, and the bottom surface of cylindrical recess 7 is provided with the spacing groove 8 the same with 5 specifications of spacing for hold spacing 5. An ejection cylinder 9 is vertically fixed at the center of the bottom of the fixed base 1, the end part of a cylinder rod of the ejection cylinder 9 is rotatably connected with a supporting plate 11 through a bearing 10, the size of the supporting plate 11 is larger than the diameter of the rotating shaft 4, the free end of the rotating shaft 4 is arranged on the supporting plate 11 through a cylindrical through hole 6, and when the ejection cylinder 9 is ejected, the supporting plate 11 can be driven to eject a limiting strip 5 of the rotating workbench 2 out of a limiting groove 8, so that the rotating workbench 2 and the supporting plate 11 can rotate together relative to the cylinder rod of the ejection cylinder 9; when the ejector cylinder 9 falls, the stop strip 5 falls back into the stop groove 8 again and the carrier plate 11 is detached from the rotary table 2. The rotary worktable 2 can be arranged in the cylindrical groove 7, and the upper surface of the rotary worktable is level with the upper surface of the fixed base 1.

And a wear-resistant copper ring 12 is arranged between the rotating shaft 4 and the cylindrical through hole 6, so that the wear between the rotating shaft 4 and the cylindrical through hole 6 can be reduced in the process of lifting the rotating workbench 2.

The following describes the usage of the present invention with reference to the drawings.

The method comprises the following steps: ejecting the ejection cylinder 9 until the limiting strip 5 is completely separated from the limiting groove 8;

step two: rotating the angle of the rotating workbench 2 according to actual requirements;

step three: ensuring that the limiting strip 5 corresponds to the limiting groove 8 under the target position;

step four: the ejection cylinder 9 is retracted, the limit strip 5 falls into the limit groove 8 again, and the rotary table 2 falls back into the cylindrical groove 7 of the fixed base 1.
