Specific embodiment
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Shown in referring to Fig.1, a kind of embodiment of tube bending jig of the utility model, the tube bending jig is used to clamp nonstandard
Bend pipe 1, including fixture base 2, the two sides in the fixture base 2, which are respectively embedded into, is provided with hydraulic slide 3, the hydraulic slide
Fixed block 4 is provided in 3, the hydraulic slide 3 slides along the fixed block 4, is fixedly installed work on the hydraulic slide 3
Dynamic claw 5, the movable jaw 5 are fixed on fixed block 4 by screw closure 51, and the movable jaw 5 is " L " type, prominent
It is set to 2 outside of fixture base, the end of the movable jaw 5 is provided with card slot 52, is arranged on the movable jaw 5
There is dismountable intermediate plate 6, the intermediate plate 6 is detachably mounted on the movable jaw 5 by nut 61, the intermediate plate 6 one
It is provided on side and distinguishes energy with the matched polygon protrusion 62 of the card slot 52, any two opposite side of the polygon protrusion 62
It enough snaps onto card slot 52, enables 6 multi-angle rotary of intermediate plate, the other side of the intermediate plate 6 is provided with and non-standard bent pipe 1
The tiger's jaw of cooperation.
Be the first embodiment of intermediate plate 6 referring to shown in Fig. 2-3: the polygon protrusion 62 is diamond shape protrusion, the diamond shape
Corresponding two sides of protrusion can snap onto card slot 52, and the angle that the polygon protrusion 62 can rotate is diamond shape
The angle of each interior angle, four interior angles of diamond shape described in the present embodiment are respectively 45 °, 135 °, 45 °, 135 °, then the intermediate plate
6 rotatable angles are respectively 45 °, 180 °, 225 ° and 360 °.Such intermediate plate 6, which is suitable for clamping, has most 4 connectors
