For solving above-mentioned technical problem, the invention provides a kind of installation limit linear cutting clamp, including: the circular support base plate that bottom surface contacts with workbench, the U-shaped pressure strip for fixing mould coordinated with support baseboard。
Described support baseboard is provided with one for placing the shoulder hole of workpiece to be processed, bottom surface in described shoulder hole is provided with an annulus, this annulus is eccentric with shoulder hole, this annulus inner ring constitutes through hole, described annulus and support baseboard are structure as a whole, one section of cambered surface of annulus is connected with inside the big external diameter of shoulder hole, middle part on described annulus and away from joint face is provided with a hole, location, inside the big external diameter of described shoulder hole and with the cambered surface junction of annulus, it is respectively provided on two sides with for the semi-circular recesses through electrode wires, it is the arc-shaped through-hole corresponding with the cut portion d of mould between described two semicircular connected in star。
Being evenly distributed with 3-5 bolt hole on described support baseboard, U-shaped pressure strip, by bolt and the bolt hole secure fit on support baseboard, is provided with packing ring between described U-shaped pressure strip and bolt。
The big 0.02-0.15mm of external diameter of the diameter of the shoulder hole of described support baseboard relatively mould (i.e. donut), is suitable for ensureing that mould can load in shoulder hole smoothly。
For avoiding the shoulder portion on mould, and again can compaction mold, the two ends, bottom of described U-shaped pressure strip are equipped with downward projection, are suitable for spacing for the shoulder portion of mould and compaction mold。
Described installation limit linear cutting clamp also includes: for the plug of jig。
Fixture adopts board-like supporting way clamping, and for ease of centering and adjustment position, the outer side surface of described support baseboard is provided with a concave station shoulder。Fixture is placed on platen face, dial gauge method for centering is coordinated to be adjusted, namely with magnetic force dial framework, dial gauge is fixed on guide frame or other position, the measurement head of dial gauge and fixture annulus contacts side surfaces, move back and forth workbench, the position of fixture is adjusted, until the beat of dial gauge pointer ranges up to required numerical value by dial gauge indicated value。Make the positioning reference plane of fixture respectively with the work top of lathe and the direction of feed x of workbench or y keeping parallelism, to ensure the relative positional accuracy between surface and the datum level cut。
During use, mould to be processed is placed in the shoulder hole of support baseboard, location aperture on mould is alignd with the hole, location on support baseboard, and plug is not inserted in hole, location by interfering, it is loaded on U-shaped pressure strip, then screwing bolts, is pressed on mould to be processed in support baseboard by U-shaped pressure strip;Further taking out plug, electrode wires is each passed through described through hole, arc-shaped through-hole and hole, location and carries out cutting processing。
The technique effect of the present invention: the use installing limit linear cutting clamp of the present invention simplifies manufacturing procedure, shorten process time, avoid part in switching process owing to knocking out of producing of unpredictable reason is damaged, improve production efficiency and product quality, save production cost, referring to the contrast table of the two kinds of processing methods in rear installation limit of specific embodiment。
