Further, as shown in fig. 9, the bottom surface of the mat 4 may be provided in a square shape, for example, in a specific embodiment, the side length of the bottom surface of the mat 4 may be provided to be 90 mm.
The dowel pin seat 100 according to one embodiment of the present invention, the mounting base 1, the outer adjuster 2, the inner adjuster 3, and the shim plate 4 may be made of S45C steel. Therefore, the structural strength of the locating pin mounting seat 100 is guaranteed, the deformation of the locating pin mounting seat 100 is reduced, and the accuracy of the part in the measuring process is guaranteed.
According to the positioning pin mounting base 100 of one embodiment of the present invention, as shown in fig. 6 and 7, two sets of positioning holes 12 (i.e., a first positioning hole 12a and a second positioning hole 12b) are provided on the mounting base 1, the two sets of positioning holes 12 have different apertures, and two positioning holes 12 of each set of positioning holes 12 are respectively located at two ends of a diagonal line of the mounting base 1. Specifically, the first positioning hole 12a and the second positioning hole 12b may be stepped holes, and the first outer aperture 91 of the first positioning hole 12a and the second outer aperture 92 of the second positioning hole 12b have different aperture sizes; the first inner aperture 93 of the first positioning hole 12a and the second inner aperture 94 of the second positioning hole 12b are different in aperture size. For example, in one particular embodiment, the first outer aperture 91 may have an aperture of 12mm, and the second outer aperture 92 may have an aperture of 18 mm; the first inner aperture 93 may have an aperture diameter of 10mm and the second inner aperture 94 may have an aperture diameter of 11 mm. Thus, the base 1 and the backing plate 4 can be fixed and mounted with a mistake-proofing function. Further, the axial dimensions of the first outer aperture 91 and the second outer aperture 92 are the same; the first inner bore 93 and the second inner bore 94 are the same in axial dimension. For example, in one particular embodiment, the first and second outer apertures 91, 92 may have an axial dimension of 12mm, and the first and second inner apertures 93, 94 may have an axial dimension of 13 mm. Further, the distance between the center points of the first positioning hole 12a and the second positioning hole 12b may be set to 55mm to 65 mm. For example, in one particular embodiment, the distance between the center points of the first and second positioning holes 12a and 12b may be 60 mm. Further, the bottom surface of the mounting base 1 and the bottom surface of the backing plate 4 are the same in size, and the positioning holes 12 correspond to the mounting holes 13 in the bottom surface of the backing plate 4 one by one, so that the mounting base 1 and the backing plate 4 can be ensured to be completely matched in the mounting process. Further, as shown in fig. 6, an indication arrow 9 may be disposed on the mounting base 1, so as to facilitate indicating the position codes on the outer position code 21 and the inner position code 32, that is, when the positioning pin 7 moves to the predetermined position, the indication arrow 9 may indicate the corresponding position codes on the outer position code 21 and the inner position code 32, and by indicating the position code indicated by the arrow 9, the corresponding rotation angle and the movement direction of the positioning pin 7 may be determined and known.
According to the dowel pin holder 100 of one embodiment of the present invention, as shown in fig. 10, when the inner adjusting member 3 itself rotates, a circular lattice 5 (i.e., a dowel pin center lattice 53 and an inner adjusting member center point 51) may be formed. Specifically, for the case that the number of sides of the inner adjusting member 3 is twelve, the inner adjusting member 3 can rotate at one shift every 30 °, and since the first distance L1 between the central axis 35 of the inner adjusting member and the central axis 311 of the positioning pin hole is 1mm, when the inner adjusting member 3 rotates one circle, the movement locus of the central axis 311 of the positioning pin hole can form a positioning pin center lattice 53 consisting of twelve points, the center of the positioning pin center lattice 53 is the inner adjusting member center point 51, and the diameter is 2 mm. Further, as shown in fig. 11, when the outer adjuster 2 and the inner adjuster 3 are simultaneously rotated, the section of the movement locus of the center axis 311 of the dowel hole is configured as a circular lattice 5 (i.e., a dowel center lattice 53 and an outer adjuster center point 52). Specifically, for example, when the number of sides of the outer adjusting member 2 is twelve, the outer adjusting member 2 can rotate at one gear every 30 degrees, and because the first distance L1 between the central axis 24 of the outer adjusting member and the central axis 35 of the inner adjusting member is 1mm (i.e., in the initial position, the central axis 24 of the outer adjusting member coincides with the central axis 311 of the dowel hole), the movement trace of the central axis 311 of the dowel hole can form a dowel center lattice 53 consisting of seventy two points when the outer adjusting member 2 and the inner adjusting member 3 rotate together. Further, as shown in fig. 12, the formed circular lattice 5 track may be composed of the outer adjuster center point 52 and six annular tracks 95, each annular track 95 containing twelve position points. The circular lattice 5 is divided into twenty-four radiation directions, and the included angle alpha of each radiation direction is 15 degrees, so that the adjustment range of the center of the positioning pin 7 is +/-2 mm. Further, as shown in fig. 13-16, each dot in the circular lattice 5 can be marked with a combination of an inner position code 32 and an outer position code 21, for example, in one specific embodiment, one dot in the circular lattice 5 is marked with 07-01, wherein the front 07 is the number on the inner position code 32 and the rear 01 is the number on the outer position code 21.
Next, a specific test method of the dowel pin mounting seat 100 according to the embodiment of the present invention is specifically described with reference to fig. 17 and 18: for example, a stamping part is precisely positioned in a die by using the positioning pin 7, and through trial and die testing, it is found that the product yield can be greatly improved by moving the positioning pin 7 from the initial point (i.e., the outer adjusting part center point 52) to the second distance L2 to the adjusting point 8. By comparing with the circular lattice 5, a location point with code 07-04 can be found closest to the adjustment point 8, and a third distance L3 is between the location point and the adjustment point, and the third distance L3 can satisfy a minimum tolerance range smaller than the actual production, for example, in a specific embodiment, the minimum tolerance range can be set to ± 0.3 mm. Therefore, the accuracy of the part in the measuring process can be ensured to the maximum extent.
According to the dowel pin mounting seat 100 of an embodiment of the present invention, if the number of the polygonal sides of the outer adjusting piece 2 and the number of the polygonal sides of the inner adjusting piece 3 are both P, the number N of the track points included in the circular lattice 5 satisfies: n ═ P2/2)+1. For example, in a specific embodiment, when the number of sides of the polygon of the outer regulating member 2 and the number of sides of the polygon of the inner regulating member 3 are twelve, the number of the locus points included in the circular lattice 5 is seventy-three.
According to the positioning pin mounting base 100 of an embodiment of the present invention, the number of the trace points located on the same circumference is P, a trace point ray 6 formed by any one trace point and a trace point on a circumference spaced by one layer from the circumference where the trace point is located intersects with a central point, and the central point is located on the central axis 311 of the positioning pin hole in the initial state. Further, the number of the trace point rays 6 is 2P, and an included angle between any two adjacent trace point rays 6 is 360/2P °. For example, in a specific embodiment, when the number P of trace points located on the same circle is twelve, the number of trace point rays 6 is twenty-four, and the included angle between any two adjacent trace point rays 6 is 15 °.
According to the dowel pin holder 100 of one embodiment of the present invention, as shown in fig. 21, the eccentricity between the inner adjuster center point 51 and the outer adjuster center point 52 is the first distance L1, and the radius R of the maximum point radial range 61 satisfies the following relationship with the first distance L1 and the maximum tolerance Y: r ═ 2L1+ Y. For example, in one particular embodiment, when the first distance L1 is 2mm, the maximum deviation Y is 0.3mm, and the radius R of the maximum point ray range 61 is 4.3 mm. Thus, by adjusting the first distance L1, the area of the maximum point ray range 61 can be changed, and the accuracy of the part in the measurement process can be ensured to the maximum extent.
In the dowel pin receptacle 100 according to one embodiment of the present invention, as shown in fig. 19-23, a tolerance-satisfying area 62 and a tolerance-failing area 63 exist in the maximum point ray range 61. Further, when the number of sides of the polygon of the outer adjusting member 2 and the inner adjusting member 3 is twelve, the ratio of the region 63 not meeting the tolerance requirements to the region 62 meeting the tolerance requirements is larger than the ratio of the region 63 not meeting the tolerance requirements to the region 62 meeting the tolerance requirements when the number of sides of the polygon of the outer adjusting member 2 and the inner adjusting member 3 is eighteen. That is, if the accuracy of the part during the measurement needs to be ensured to the maximum, the positioning pin 7 can obtain more positioning pin center lattices 53 by increasing the number of the polygon sides of the outer adjusting member 2 and the inner adjusting member 3. The distance between the tracks in the center dot matrix 53 of the positioning pin can be reduced to the allowable range of the tolerance, and the proportion of the final area 62 meeting the tolerance requirement in the maximum point ray range 61 is higher.
In summary, according to the positioning pin mounting seat 100 of the embodiment of the present invention, the horizontal position of the positioning pin 7 in the tool can be changed by adjusting the angles of the outer adjusting part 2 and the inner adjusting part 3; through the thickness of adjustment backing plate 4, can change the working height of locating pin 7, and then realize the purpose of part accurate positioning in the frock.
