Further specify below in conjunction with the scheme of accompanying drawing the utility model.

As shown in Figure 1, flexible locating support is used in the three-dimensional laser cutting of the utility model, comprises rack platform 3, clamp holder 2, local section clamp 1; Evenly be interval with some horizontal pin-and-

holes

71,72 and

vertical screw hole

81,82 on the rack platform 3; Clamp holder 2 is through pressing plate 4 location, and pressing plate 4 is fixed on the rack platform 3 through screw 10, and the crown center place of clamp holder 2 has the mounting groove 21 that is used to install local section clamp 1; The bottom of clamp holder 2 is provided with four bottom pin-and-holes 221,222,223 of cross arrangement; 224; Two wherein relative arbitrarily bottom pin-and-holes 221,223 or 222,224 all can match with two adjacent horizontal pin-and-

holes

71,72 on the platform, and are as shown in Figure 5.

Like Fig. 2, Fig. 3 and shown in Figure 4, the middle part indent of clamp holder 2 forms an inner fovea part 23, and the cross section of inner fovea part 23 is a rectangle; Pressing plate 4 is two, and is as shown in Figure 6, and every block pressur plate 4 has the rectangular block of pressing plate groove 41 for the middle part; As shown in Figure 1, about inner fovea part 23 or both sides, front and back are withstood by two block pressur plates 4 respectively, and every block pressur plate 4 supports through pressing plate pier 9 respectively; Pressing plate pier 9 is positioned on the rack platform 3; Two screws 10 pass two

vertical screw holes

81,82 on two pressing plate grooves 41 and the rack platform respectively successively, and pressing plate 4 is fixed on the rack platform 3.

As shown in Figure 7; The bottom of local section card 1 is provided with two first pin-and-holes 11; The upper side place of clamp holder 2 has two second pin-and-holes 24 and a screw hole 25; Two cylindrical pin with internal threads that are used to locate 5 pass two second pin-and-holes 24 and 11, one hexagon socket cap head screws 6 of two first pin-and-holes respectively successively and pass screw hole 25 local section card 1 and clamp holder 2 are fixed, and are as shown in Figure 1.

As shown in Figure 1; Also be provided with on the rack platform 3 and the bolt hole 12 of the original platform of lathe with bolt; This rack platform 3 can become all size specification according to the original platform size design of lathe, according to the original platform size of lathe, is spliced into the integral cutting platform again; Entire bracket platform 3 is heat-treated, to guarantee the intensity and the durability of rack platform 3.

The assume diamond in shape arrangement mode in 2 * 2 quaternarys bunch hole of horizontal pin-and-hole on the rack platform 3 of the utility model and vertical screw hole; Vertically the pitch-row of screw hole is bigger, is 100mm, and laterally the pitch-row of pin-and-hole is less; Be 30mm; The clamp holder of employing standard cooperates with the local section clamp and supports sheet metal component, and local section clamp and clamp holder are matched in clearance, and adopts standard pin (cylindrical pin with internal thread 5) location; The local section clamp is that a cut is made, to guarantee local section clamp precision.

Clamp holder 2 is the steel standard component of length and width 60mm, high 200mm, and crown center has a wide 3mm, and the mounting groove 21 of dark 40mm is used for assembling local section clamp 1; Inner fovea part 23 wide dark 20mm; Distance between relative two the bottom pin-and-

holes

221 and 223 in bottom (or 222 and 224) is 30mm; It is corresponding with two horizontal pin-and-

holes

71 and 72 on the rack platform 3; Therefore clamp holder 2 can 90 degree rotations, its rotation back two other bottom pin-and-hole can be corresponding with adjacent two horizontal pin-and-holes on the platform relatively.

Local section clamp 1 is that a thickness is the steel plate of 3mm; Cylindrical pin with internal thread 5 is of a size of

hexagon socket cap head screw 6 and is of a size of M10 * 35, is standard component.

Installation method of the present invention is following: at first with bolt rack platform 3 and lathe platform are fixed; Then two pins are penetrated horizontal pin-and-

hole

71 and 72 respectively; Again clamp holder 2 is penetrated these two pins (the bottom pin-and-hole of clamp holder 2 is aimed at these two pins and penetrated); And pressing plate 4 is fixed on the rack platform 3 with screw 10; Then a pair of first pin-and-hole 11 of local section clamp 1 is aimed at a pair of second pin-and-hole 24 at clamp holder 2 tops, after having good positioning with two cylindrical pin with internal threads 5, fixed with a hexagon socket cap head screw 6 again.

Mounted according to the method described above flexible locating support is as shown in Figure 1, if it cuts locating support for left cut, then with clamp holder 2 together with local section clamp 1 Rotate 180 degree, just can be used as right cut and cut locating support and use.
