Preferably, described upper die of bending machine fixture also comprises bending compensate for height guiding mechanism, and described bending compensate for height guiding mechanism comprises Height Adjustment plate, eccentric shaft and clamp fixing plate; Eccentric shaft is located clamping plate holder and Height Adjustment plate through clamping plate holder and Height Adjustment plate, then by screw, Height Adjustment plate is locked on clamping plate holder; Clamp fixing plate is screwed in Height Adjustment plate top, when bending compensation needs to adjust upper die clamper height, the screw that unclamps locking Height Adjustment plate, rotates and adjusts eccentric shaft respectively, the relative clamp fixing plate of clamping plate holder is offset up and down and realizes Height Adjustment.

Preferably, on described eccentric shaft, be also socketed eccentric shaft back-up ring.

What preferably, on described clamping plate holder, corresponding eccentric shaft wore is provided with adjustment graduation indication in hole week.

Preferably, described clamping plate holder side is Y-shaped, and top forms the clip slot that holds Height Adjustment plate, and Height Adjustment plate is located in clip slot.

Preferably, described front plate, rear plate are movably connected on holder both sides by being socketed with the pin of spring; The both sides of the position that follow-up rolling ring is installed on front plate, rear plate are respectively equipped with the second connecting pin.

Compared with prior art, beneficial effect of the present invention is: described upper die clamper has solved the defect that existing fixture exists completely, and front and back clamping plate all can be controlled easily and clamped or unclamp by handle, use more flexible; The special height regulating mechanism arranging can be adjusted fixture height accurately by scale, adjusts convenient.

The specific embodiment

Understand technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.

As in Figure 3-5, in the present embodiment, described upper die of bending machine fixture comprises clamp locking mechanism and bending compensate for height guiding mechanism.Wherein, clamp locking mechanism comprises clamping plate holder 1, front plate 2, rear plate 3, lock handle 4, clamping plate locking jacking block 9 and follow-up rolling ring 10 etc.Described bending compensate for height guiding mechanism comprises two Height Adjustment plates 5, two eccentric shafts 7 and clamp fixing plate 6.Bending compensate for height guiding mechanism integral body is positioned at the top of clamping plate holder 1, and clamp locking mechanism integral body is positioned at the bottom of clamping plate holder 1.

1 two sides of clamping plate holder become Y-shaped, and two Height Adjustment plates 5 lay respectively in two Y word clip slots of clamping plate holder 1 top.Two eccentric shafts 7, respectively through the installing hole on clamping plate holder 1 and Height Adjustment plate 5, by clamping plate holder 1 and Height Adjustment plate 5 location, are also socketed eccentric shaft back-up ring 14 on eccentric shaft 7.The hole week that on clamping plate holder 1, corresponding eccentric shaft wears is provided with adjustment graduation indication.Screw 8 is locked Height Adjustment plate 5 on clamping plate holder 1; Clamp fixing plate 6 use screws 15 are fixed on Height Adjustment plate 5 tops, when bending compensation needs to adjust upper die clamper height, unclamp the screw 8 of locking Height Adjustment plate 5, according to the distance of need adjustment, be converted to adjustment scale, rotate respectively and adjust scale corresponding to eccentric shaft 7 rotation, make the relative clamp fixing plate 6 of clamping plate holder 1 be offset and realize Height Adjustment up and down.

Front plate 2, rear plate 3 are arranged at clamping plate holder 1 both sides, bottom, by being socketed with the pin 15 of spring, are movably connected on holder 1 both sides; Clamping plate holder 1 inner chamber is fixed and be placed in to lock handle 4 and clamping plate locking jacking block 9 use handle coupking shafts 13, and arm pivot post 11 enters inner chamber and is arranged in handle coupking shaft 13 from top through clamping plate holder 1; Clamping plate locking jacking block 9 both sides arrange respectively follow-up rolling ring 10, and follow-up rolling ring 10 is arranged on front plate 2 and rear plate 3 with rolling loop mapping screw 12 respectively, twist-lock handle 4, drives clamping plate locking jacking block 9 rotate and then promote follow-up rolling ring 10, makes forward and backward clamping plate clamp or unclamp.The both sides of the position that follow-up rolling ring 10 is installed on front plate 2, rear plate 3 are respectively equipped with the second connecting pin 16.
