Detailed description of the invention
Accompanying drawing 1 is the structural representation of the vertical locator of prior art, and accompanying drawing 2 is structural representations of the horizontal locator of prior art, and in figure, l is alignment pin, and 2 is locating piece, and 3 is locking nut, and A is by the parts of locating.As seen from the figure, so-called locator generally includes vertical locator and horizontal locator, and the structure of two kinds of locators is similar, includes alignment pin 1, locating piece 2 and locking nut 3.Alignment pin 1 is divided into three sections, is followed successively by thread segment, positioning section and hold-down segment, wherein, thread segment and locking nut match, fabrication hole on the diameter of positioning section and parts and the locating hole on locating piece 2 match, and the diameter of hold-down segment is greater than fabrication hole, and end face and positioning section axes normal.Be provided with locating hole in the middle part of locating piece 2, the positioning section diameter of its size and alignment pin matches, the end face of locating hole and the axis perpendicular of locating hole.When specifically using, from the side of parts, alignment pin positioning section is inserted the fabrication hole parts, the alignment pin of parts opposite side inserts locating piece, and guarantee that the locating hole on locating piece is sleeved on the positioning section of alignment pin, screw locking nut, the fabrication hole on the parts of more than two or two can be made to overlap.Due to alignment pin hold-down segment end face and positioning section axes normal, the end face of locating hole and the axis perpendicular of locating hole, therefore, can ensure that the fabrication hole on the parts of more than two or two overlaps accurately.But this kind of locator needs to operate respectively in the both sides of parts just can complete to the positioning action of same station, to some special stations, even needs two people just can complete at the both sides compounding practice of parts respectively.In addition, locking nut needs to screw in from the termination of alignment pin thread segment, and need the time that cost is longer, efficiency is lower.The problems such as obviously, prior art locator also exists inconvenient operation, and the longer and efficiency of positioning clamping spent time is lower.
Accompanying drawing 3 is structural representations of the utility model fabrication hole key formula locator alignment pin, accompanying drawing 4 is B-B schematic diagrames of accompanying drawing 3, accompanying drawing 5 is three-dimensional structure schematic diagrames of the utility model fabrication hole key formula locator locating piece, accompanying drawing 6 is front elevational schematic of the utility model fabrication hole key formula locator locating piece, accompanying drawing 7 is C-C schematic diagrames of accompanying drawing 6, accompanying drawing 8 is front elevational schematic of the utility model fabrication hole key formula locator locking nut, accompanying drawing 9 is D-D schematic diagrames of accompanying drawing 8, in figure, 11 is thread segment, 12 is positioning section, 13 is locking section, 21 is locating surface, 22 is locating hole, 23 is pin hole, 24 is lining, 25 is pin, 31 is locating surface, 32 is screwed hole, 33 is power-assisted hole, 34 is annular knurl line.As seen from the figure, the utility model fabrication hole key formula locator comprises alignment pin, locating piece and locking nut, it is characterized in that, alignment pin is divided into thread segment 11, positioning section 12 and locking section 13 from top to bottom successively, thread segment 11 and locking nut screwed hole 32 match, positioning section 12 matches with the aperture of the fabrication hole on parts and locating piece lining 24 endoporus, and locking section 13 shape is that symmetrical circle lacks shape, and the gap length between the width that its circle lacks and locating piece pin 25 matches; Locating piece upper surface is locating surface 21, and top is provided with locating hole 22, is set with lining 24 in locating hole 22, and middle part radial direction is provided with two pins 25; Locking nut lower surface is locating surface 31, and there is internal thread 32 at middle part, and power-assisted hole 33 is arranged at top, and outside is annular knurl line 34.
Accompanying drawing 10 is front elevational schematic of the utility model fabrication hole key formula locator using state, and in figure, 01 is alignment pin, and 02 is locating piece.03 is locking nut, and A is by the parts of locating.As seen from the figure, locating piece, on alignment pin, when specifically using, is placed on by the side of positioned zero parts by the locking nut of the utility model fabrication hole key formula locator in advance spinning, from by the opposite side of positioned zero parts insert alignment pin, and after insertion puts in place spinning alignment pin 90 degree.Because alignment pin locking section shape is that symmetrical circle lacks shape, gap length between the width that its circle lacks and locating piece pin matches, the circle of alignment pin locking section lacks shape and can enter into the bottom of pin through space two pins, now after spinning alignment pin 90 degree, two semicircles of locking section are just stuck between two pins, must not exit.Now, screw the locking nut of spinning on alignment pin in advance, the lower surface (i.e. locating surface) of locking nut and upper surface (i.e. locating surface) clamping of locating piece are by positioned zero parts, and alignment pin positioning section ensure that by the accurate overlap in positioned zero component technology hole, realize by the accurate location of positioned zero parts.When needs take off the utility model fabrication hole key formula locator, unclamp locking nut, again spinning alignment pin 90 degree, the circle of alignment pin locking section lacks and can exit from space between two pins, namely takes off the utility model fabrication hole key formula locator.Because the major part operation of the utility model fabrication hole key formula locator is all in the side being decided to be parts, therefore, do not need two people's co-operatings.Be arranged on the annular knurl line on locking nut surface, can hand Screw nut, improve operating efficiency.When needs high-torque tightening nut, can insert metallic rod in power-assisted hole, what increase nut screws power.Due to the utility model fabrication hole key formula locator locking nut in advance spinning on alignment pin, therefore, when needs screw locking nut, do not need from the termination of screw thread, only need to rotate a few circle and get final product indentation, both simplified operation, and turn improved efficiency.Further, the alignment pin of the utility model fabrication hole key formula locator, between locating piece and locking nut, the size relationship that Existence dependency is not stronger, not only structure is simple, and process technology requires also lower, makes holistic cost lower.
Obviously, the Advantageous Effects of the utility model fabrication hole key formula locator is easy to operate, quick, does not need two people's co-operatings, effectively raises location efficiency.Further, structure is simple, process technology requires low, and cost is lower.
