[0022] Exemplarily, the locking portion includes at least one locking bolt, which is threadedly connected to a screw hole opened on the outer ring seat, and one end of the locking bolt abuts against the inner embedded ring.
[0023] In some embodiments, the indexable top bending chuck disclosed herein further includes a sliding adjustment mechanism, which includes a stretching beam and a support roller, wherein the support roller is mounted to the outside of the adjustment bracket and the support roller is mounted on the stretching beam.
[0024] Exemplarily, the sliding adjustment mechanism also includes a positioning pin, the stretching beam is provided with a plurality of first positioning holes at equal intervals along the length direction, and a second positioning hole is provided on the outer side of the adjustment bracket; the positioning pin passes through one of the first positioning holes and is inserted into the second positioning hole.
[0025] Exemplarily, the chuck body includes a shell, a beveled wedge block, a cylinder mounting seat and a clamp, a cylinder mounting seat for mounting the cylinder is fixedly mounted on one side of the shell, the beveled wedge block is located on one side of the cylinder mounting seat, and the clamp is fixed to the beveled wedge block.
[0026] Exemplarily, a cavity is provided in the shell, the vertical width of the cavity gradually decreases in the direction away from the cylinder mounting seat, and rails are fixedly installed on the upper and lower cavity walls of the cavity, and the inclined wedge block is slidably connected to the rails.
[0027] Specifically, Figure 1 and Figure 3 As shown, the present invention relates to a rotatable top bending chuck, comprising an adjusting bracket 1, an outer ring seat 101, an inner ring 102, a locking bolt 103, a chuck body 2, an outer shell 201, a cavity 202, a bevel wedge 203, a cylinder mounting seat 204, a clamp 205, a track 206, a sliding adjustment mechanism 3, a supporting roller 301, a positioning pin 302, and a stretching beam 303.
[0028] The oil cylinder is fixed on the oil cylinder mounting seat 204, and a vertical slideway is installed between the oil cylinder and the inclined wedge block 203 so that the two can slide in the up and down directions. The inner ring 102 is sleeved on the outer shell 201 of the chuck body 2, and the inner ring 102 and the outer shell 201 are fixed by bolts, and the inner ring 102 is assembled into the outer ring seat 101, and the two are connected with clearance fit, and then a screw hole is opened on the outer ring seat 101, and the locking bolt 103 is screwed into the screw hole so that the locking bolt 103 presses the inner ring 102, and the support roller 301 is installed on the outside of the outer ring seat 101, and then the support roller 301 is placed on the stretching beam 303, and the positioning pin 302 is inserted into the first positioning hole on the stretching beam 303, and passes through the second positioning hole on the outer ring seat 101.
[0029] When in use, two top bending chucks are used together to clamp both sides of the product.
[0030] Usage and steps:
[0031] 1) Pull out the positioning pin 302, so that the positioning pin 302 is pulled out from the second positioning hole on the outer ring seat 101 and the first positioning hole on the stretching beam 303, move the adjustment bracket 1, and roll it along the length direction of the stretching beam 303 through the supporting roller 301, and move and adjust it to the required position, that is, the distance between the two chuck bodies 2 is adapted to the product width; align the second positioning hole with the first positioning hole, and insert the positioning pin 302 into the first positioning hole and the second positioning hole for positioning;
[0032] 2) The product to be bent is placed between the two chuck bodies 2, and the oil cylinder pushes the inclined wedge block 203 to slide on the track 206 and move away from the oil cylinder mounting seat 204. Since the vertical width of the cavity 202 gradually decreases in the direction away from the oil cylinder mounting seat 204, the inclined wedge block 203 drives the clamp 205 to move toward the middle of the cavity 202 to clamp the product;
[0033] 3) The external bending device bends the product, wherein the bending twist is controlled by adjusting the angle of the profile, the locking bolt 103 is loosened, and the chuck body 2 is manually rotated to adjust the angle. After adjustment, the locking bolt 103 is tightened to compress the embedded ring 102;
[0034] 4) After top bending, the oil cylinder contracts, driving the inclined wedge block 203 to move closer to the oil cylinder mounting seat 204. The inclined wedge block 203 drives the clamp 205 to release the product, remove the product, and complete the processing.
[0035] The chuck design in the prior art compensates the angle by designing the fixture 205, and at the same time, the trimming fixture 205 or the shim is adjusted through multiple tests in the later stage to meet the need to properly adjust the angle of the profile to control the bending and twisting degree, which is time-consuming and labor-intensive. Compared with the prior art, the technical solution uses a specific indexable top bending chuck, and by adding an adjustment bracket 1 outside the traditional chuck, the chuck is 360° adjustable in the adjustment bracket 1, which meets the need to properly adjust the angle of the profile to control the bending and twisting degree. Further, the adjustment bracket 1 has a locking part, which is locked and positioned after adjustment to maintain the adjusted angle position.
