Detailed Description
The positioning pin positioning structure of the present invention will be further described below with reference to specific embodiments to help those skilled in the art to understand the technical solution of the present invention more completely, accurately and deeply.
Example 1
As shown in fig. 1 to 5, the positioning pin positioning structure of the present embodiment includes a positioning pin 20, a limiting post 30, and a fixture connecting block 40. The locating pin 20 is provided with a convex ring 22 which divides the locating pin into an upper column body 23 and a lower column body 25, the outer wall surface of the upper column body 23 is a limiting surface, and the outer wall of the lower column body 25 is provided with a plurality of limiting grooves 21. The stopper groove 21 extends inwardly from the outer wall surface in a direction perpendicular to the outer wall surface, and has a depth of 2 to 3 mm. The adjacent limiting grooves are spaced at a certain distance in the axis direction of the positioning pin. The fixture connecting block 40 is provided with a through positioning pin mounting hole 41, and the side wall of the fixture connecting block 40 is provided with a limit column mounting hole 42 communicated to the positioning pin mounting hole 41. The positioning pin 20 is placed in the positioning pin mounting hole, the positioning pin 20 and the clamp connecting block 40 are positioned through the limiting post 30 penetrating through the limiting post mounting hole 42 and the limiting groove 21, the positioning pin 20 is fastened through the mounting nut 50 mounted on the lower post body 25, and the sheet metal part 10 is positioned on the limiting surface of the upper post body 23.
The positioning structure of the present embodiment is applied as follows:
(1) the lower column body 25 of the positioning pin 20 is provided with 3 limiting grooves 21 (the number of the limiting grooves is changed according to the actual situation);
(2) the limiting grooves 21 are round holes with the diameter of 3mm and penetrate into the lower column body 25 by 2-3mm, and the distance between every two limiting grooves 21 in the axis direction of the positioning pin is 5 mm;
(3) a positioning pin mounting hole 41 and a limiting column mounting hole 42 are formed in the fixture connecting block 40;
(4) the aperture of the limiting column mounting hole 42 is consistent with the diameter of the limiting groove 21;
(5) placing the positioning pin 20 into the positioning pin mounting hole 41, wherein one limiting groove 21 is overlapped with the limiting column mounting hole 42;
(6) the limiting column 30 is used for connecting the limiting column mounting hole 42 and the limiting groove 21, and limiting is carried out on the positioning pin;
(7) fastening the positioning pin 20 using the mounting nut 50;
(8) the sheet metal part 10 is limited by the limiting surface 23 of the positioning pin 20, the contact position of the sheet metal part 10 needing positioning after long-term use and the positioning pin body 20 is abraded, after the limiting surface of the upper cylinder 23 of the positioning pin 20 reaches a certain abrasion loss, the limiting surface positions of the sheet metal part 10 and the upper cylinder 23 can limit the positioning pin by using the limiting grooves 21 at other positions, and therefore accurate positioning is performed by using the non-abraded limiting surface.
For those skilled in the art, the specific embodiments are only exemplary descriptions of the present invention, and it is obvious that the present invention is not limited by the above-mentioned manner, and various insubstantial improvements are all within the protection scope of the present invention as long as the technical solution of the present invention is adopted.
