Abstract

The invention discloses a forward-press-fitting diode fixture with a pressure sensor. The forward-press-fitting diode fixture comprises the pressure sensor, a first upper die block, a second upper die block, a press head, a discharge plate, a spring, a shouldered guide column and an electrode plate positioning pin component. Strong magnets are disposed in rear of an upper fixing groove and a lower fixing groove. The pressure sensor is disposed in a sensor holding hole of the first upper die block, and the diameter of the hole is 0.02-0.04mm larger than the outer diameter of the sensor. The second upper die block is fastened to the first upper die block through a bolt. The forward-press-fitting diode fixture has the advantages that factors causing inaccuracy of pressure values due to decentraction of a diode and a corresponding hole of an electrode plate are eliminated to the greatest extent; clamping groove type push-and-pull die change is adopted, the strong magnets are disposed in rear of the fixing grooves, screw fixation is not needed, and accordingly, die change time is reduced by 80%.

Description

A kind of positive press-fit diode fixture with pressure transducer

Technical field

The present invention relates to a kind of pressing clamp, belong to diode technology of pressure mounting field, specifically a kind of band pressure transducer Positive press-fit diode fixture.

Background technology

At present, the press-fit approach of the diode pressing clamp with pressure transducer: first diode is inverted, is positioned over down On pressure head in mould stripper emptiness avoiding hole, then it is put in counter for pole plate on stripper, pressure transducer is put in the bottom of lower molding head Put, above-mentioned press-fit approach has definitely drawback: to smoothly put into diode in stripper emptiness avoiding hole, that means that The empty avoiding bore dia of stripper have to be larger than the diameter of diode;So, diode is impossible to concentric with emptiness avoiding hole, adds Pole plate is positioned over the tolerance on stripper, and diode arises that different degrees of bias with the position in corresponding pole plate hole, then can Lead to the pressing-in force numerical value that sensor detects inaccurate, thus leading to this to need the project of emphasis management and control to be in shape out of control State, there is great risk in product quality.In addition, sharing because mould bases is multiple product core rods, when changing core rod, this structure is pressed from both sides Tool needs to dismantle each 4 screws of upper and lower mould, and mould replacing time is long, affects yield.

Content of the invention

The problem existing for above-mentioned prior art, the present invention provides a kind of positive press-fit diode with pressure transducer Fixture, diode and pole plate corresponding aperture decentraction and lead to the inaccurate factor of pressure value, make diode pressing-in force management and control More accurate, reduce product quality risk.

To achieve these goals, the technical solution used in the present invention is: a kind of forward direction with pressure transducer press-fits two Pole pipe fixture, including top mold frame, upper fixing groove, lower module, lower fixing groove, lower mold holder, upper mould be firmly spacing, the firmly spacing and of lower mould Lower mould firmly spacing two;Upper fixing groove is fastened in top mold frame using bolt, and upper mould is firmly spacing to be arranged on top mold frame both sides;Lower fixation Using being bolted on lower mold holder, lower mould firmly spacing one and lower mould firmly spacing two are arranged on lower mold holder both sides to groove;

Also include pressure transducer, upper module one, upper module two, pressure head, stripper, spring, shoulder leader pin and pole plate fixed Position pin, strong magnetic is placed at upper and lower fixing groove rear, and pressure transducer is positioned in the sensor putting hole of upper module one, aperture is big In sensor external diameter 0.02-0.04mm;Upper module two is fastened on upper module one using bolt;Pressure head is placed on upper module two In corresponding putting hole, aperture is more than pressure head external diameter 0.03-0.05mm, and pressure head end diameter is less than upper module one and upper module two Counter bore hole diameters 0.4-0.6mm;The rotator bolts such as stripper use are fastened on upper module one, and spring housing is waiting outside rotator bolt, band shoulder Guide pillar respectively penetrates upper module one, upper module two, stripper and upper module one, upper module two interference fits, with discharging sheet separation Cooperation.

Design further, in lower module, setting band is takeed on guide pin bushing and cooperated with shoulder leader pin.

Design further, top mold frame top arranges die shank.

Compared with existing mold: fixture, in die change, core rod is extracted out, fast and easy;When in use, first will Pole plate is positioned on lower module according to alignment pin, then by diode lead downwards, is positioned in pole plate press mounting hole, startup press-fits Equipment, upper mould pushes, and three shoulder leader pins 15 initially enter band shoulder guide pin bushing, and then, stripper is contacted with pole plate, spring contraction, Stripper compression pole plate makes it not be subjected to displacement, and equipment continues to push, and pressure head contact diode simultaneously continues to press-fit downwards, and upper mould is hard Spacing and lower mould is firmly spacing fit after, pressure transducer detects pressing-in force, press-fits and completes;Eliminate to greatest extent because of two poles Pipe and pole plate corresponding aperture decentraction and the inaccurate factor of pressure value that leads to.Die change takes card slot type push-and-pull die change, fixing Groove rear carries strong magnetic, fixes without screw, mould replacing time decreases 80%.
