3. beneficial effect
Compared with the prior art, the invention has the benefit that
(1) present clip adjusts the height of upper regulating part by angle adjusting mechanism, rotates die holder, until clamping position
Interior upper mold cutting edge face to be processed is in the Working position of relative level, and by the fixed support die holder of lower support element, obtains
The upper mold Special Fixture for Machining arrived, it is ensured that do not have to replacement milling machine structure, used with adapting to the bending machine of milling angle multiplicity
Upper mold；And the blade angle variation of the upper mold due to that need to process is generally not very greatly, when the rotation for needing to finely tune die holder
When angle, using the automatic lifting mode of other such as cylinders etc, the amplitude of accommodation of support column can be made excessive without being able to satisfy
The cutting edge face of upper mold reaches the requirement of Working position, the voussoir that the present invention uses a pair of of inclined-plane to cooperate as angular adjustment machine
Structure may be implemented to continuously adjust support column, and the height change small to its reaches the degree fine-tuned, i.e., to die holder
Positioning accuracy it is high, in order to be suitable for the Working position that the upper mold cutting edge face of angular diversity is in relative level；
(2) the upper regulating part of present clip is cylinder, and upper limit position groove is the arc groove matched with upper regulating part, can
The area of support is contacted in increase between regulating part and upper limit position groove, and is bolted between upper regulating part and die holder, side
Just while disassembly, when also can guarantee that lower regulating part is in stationary state, rotation is not generated, influences the milling in upper mold cutting edge face
Angle reinforces the stability of strutting system to upper mold, if taking for example between upper regulating part and die holder or between die holder and support column
Hinged connection type can limit the movement of regulating part, cannot but limit the rotation of regulating part, will affect upper mold
The milling angle in cutting edge face；
(3) lower support element of present clip be cylinder, be placed in the V-groove of pedestal, and under the right angle on die holder
Limiting slot contact, the setting of more contact points, the pressure generated when milling cutting edge face can be dispersed prevent the cylindrical side of lower support element
It skids and the machining angle in the cutting edge face on upper mold is made to deviate Working position in face；When die holder is rotated around lower support element, due to
Contact surface between lower support element and die holder, between lower support element and pedestal is small, and the force of rolling friction of lower support element is small, can be with
The friction loss for reducing fixture, improves the service life of fixture；The arch gland that die holder and lower support element are fixed on the base,
It is equipped with the arc groove cooperated with lower support element and arc groove both sides among it and cooperates the bottom contacted with the V-groove both sides of pedestal
Face, the downward pressure generated when being conducive to gland milling cutting edge face, downwardly and outwardly passes to adjacent part, due to spiral shell
Bolt fixes gland, can resist arch gland each section and be under pressure the extrapolability of generation, thus arch gland can bear it is huge
Pressure is conducive to the stability of strutting system of present clip；
(4) die holder of present clip is equipped with clamping plate, the mounting groove of the boss cooperation insertion upper mold side on clamping plate
In, further upper mold can be clamped in and clamped on position, not only prevent upper mold disengaging from clamping position, upper mold can also be limited and existed
Moving up and down on position is clamped, guarantees that the milling angle in upper mold cutting edge face is in relative level Working position；
(5) present invention is by measuring the distance of shaft centers of upper regulating part and lower support element, the cutting edge face of upper mold and supporting surface it
Between angle, the distance of shaft centers line between lower support element and upper regulating part and the angle between supporting surface, lower support element axle center are arrived
The vertical range in reference support face, these preset parameters of the bottom surface radius of upper regulating part, founding mathematical models can be calculated precisely
Upper regulating part bottom surface to reference support face vertical range, in order to select the support column of appropriate length or be fine-tuning to support column
Desired height makes the milling angle in upper mold cutting edge face be in relative level Working position, guarantees its positioning accuracy height；
(6) inventive die fixture for processing, structure is simple, and design is rationally, easily fabricated.
