Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific examples, which are not intended to be limiting, so that those skilled in the art will better understand the invention and practice it.
Referring to fig. 1, 2, 3, 4 and 5, the embodiment discloses a polygonal self-centering measuring base, which comprises a body 1, wherein a centering hole 11 penetrating through the body 1 is arranged in the body 1, a hexagonal or polygonal product is placed into the body 1 through the centering hole 11, the centering hole 11 is polygonal, and the hexagonal or polygonal product can be positioned in an auxiliary manner through the centering hole 11 with the polygonal shape;
the ball 12 is placed in the upper end of the body 1 through a plurality of containing cavities which are uniformly arranged, the containing cavities are circumferentially distributed on the body 1, the ball 12 is made of steel materials, the number of the containing cavities is not less than 4 and is even, the containing cavities are communicated with the outer side wall of the body 1 and the centering holes 11, the diameter of the ball 12 is equal to the diameter of the hole communicated with the outer side of the body 1, the diameter of the hole communicated with the centering holes 11 is smaller than the diameter of the ball 12 and larger than the radius of the ball 12, each ball 12 only partially penetrates into the centering holes 11, an O-shaped ring 13 for preventing each ball 12 from falling from the outer side of the upper end of the body 1 is sleeved outside the upper end of the body 1, the O-shaped ring 13 is pressed by the plurality of balls 12 but is blocked outside, so that the O-shaped ring 13 can provide an even clamping force, the elastic centering of the hexagonal or polygonal product is realized through the plurality of balls 12 and the O-shaped ring 13, the annular ring 13 is further arranged on the annular groove 14, and the annular groove 14 is further arranged around the annular groove 14, and the annular groove 14 is formed around the annular groove 14;
the elastic plunger 15 is screwed in from the outer side of the body 1 and partially penetrates out of the inner side wall of the body 1, the elastic plunger 15 is directly contacted with a hexagonal or polygonal product after being screwed in the body 1, the hexagonal or polygonal product is finely adjusted and positioned through the elastic plunger 15, further, a fixing piece 16 which is propped against the side wall of the elastic plunger 15 is arranged below the elastic plunger 15, the fixing piece 16 is selected from parts such as a screw, a bolt and the like, the elastic plunger 15 is inevitably loosened after being placed in the body 1 and taken out of the hexagonal or polygonal product for many times, the elastic plunger 15 is fastened and adjusted and supported through the fixing piece 16, the fixing piece 16 is screwed in from the bottom of the body 1, a fixing hole 17 is formed between the bottom of the body 1 and the elastic plunger 15, and meanwhile, a groove 18 is formed at one side of the bottom of the body 1, and part of the fixing hole 17 is exposed through the groove 18, so that the fixing piece 17 is more convenient to adjust;
the positioning shaft 2 is inserted and connected to the bottom of the body 1, a first positioning hole 21 and a second positioning hole 22 penetrating through the positioning shaft are sequentially formed in the inner side of the positioning shaft 2 from top to bottom, the first positioning hole 21 is matched with the centering hole 11, the aperture of the second positioning hole 22 is smaller than that of the first positioning hole 21, and the positioning shaft 2 is used for placing the lower part of a hexagonal or polygonal product.
Furthermore, the centering hole 11 is further provided with a marking opening 111, the marking opening 111 is a notch with a regular or irregular shape formed on the side edge of the centering hole 11 again, and the marking opening 111 is matched with a hexagonal or polygonal product to identify whether the hexagonal or polygonal product is in place or not.
