(5) upper contiguous block (3) is riveted respectively, and tightening structure is with the contiguous block riveted with steel band and with supporting plate weld
U-shaped piece is tightened up steel band, and contiguous block is threaded, and nut is used cooperatively with contiguous block, rotating nut, pulls contiguous block,
Steel band is tightened up.Clamp material is from the higher 2Cr25Ni20 of heat resistance.
The tightening structure of this fixture is to tighten up steel with the contiguous block riveted with steel band and with supporting plate weld to be upgraded to U-shaped piece
Band, contiguous block is threaded, and nut is used cooperatively with contiguous block, rotating nut, pulls contiguous block, and steel band is tightened up.
Devise baffle arrangement.Frock has the trend laterally ejected, and side bullet is not avoided, and U-shaped piece of leading portion is slotted,
Block, U-type groove and block straight pin and mode connects for screw are put into groove.
Advantages of the present invention：
1) thin plate quenching fixture compacted position is product surplus, and product is unlikely to deform；
2) quenching precision is high：With positioning finger setting, quenching precision, rate of reducing the number of rejects and seconds are improved.
3) convenient control is clamped：Fixture steel belt clamping, it is U-shaped with the contiguous block riveted with steel band and with support plate weld
Block tightens up steel band, and nut is used cooperatively with contiguous block, rotating nut, pulls contiguous block, and steel band is tightened up.
4) the higher 2Cr25Ni20 of material selection heat resistance, it is to avoid due to the deformation of products that frock is deformed and is produced.
5) illustrate
Fig. 1 show a kind of structural representation of curved sheets quenching fixture of the invention；
Fig. 2 show the structural representation that a kind of curved sheets quenching fixture of the invention is clamped；
Fig. 3 show a kind of structural representation of side stand component of curved sheets quenching fixture one of the invention；
Wherein, supporting plate 1, steel band 2, contiguous block 3, supporting plate 4, steel band 5, baffle plate 6, alignment pin 7, link 8,
Link 9, U-shaped piece 10, U-shaped piece 11, alignment pin 12.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples：
Referring to Fig. 1, it is a kind of structural representation of curved sheets quenching fixture of the invention.The curved surface quenching is thin
Board clamp includes supporting plate 1, and steel band 2, contiguous block 3, supporting plate 4, steel band 5, baffle plate 6, alignment pin 7 connects
Connect frame 8, link 9, U-shaped piece 10, U-shaped piece 11, connection fastener etc. between alignment pin 12, and each part.
Wherein, supporting plate is to be used to support curved sheets, and two supporting plates are connected with two links, and alignment pin is to be used for fixture
Positioning, steel band, contiguous block, U-shaped piece, baffle plate be used for clamp, steel band compress position be curved sheets product
Residue position.After the completion of positioning compression, curved sheets quenching fixture can be put into nitrate groove, carry out Quenching Treatment one
Taken out after the section time, product is can be taken off after cooling.
Referring to Fig. 2, the structural representation that a kind of curved sheets quenching fixture of the invention is clamped.The curved sheets are quenched
Fiery fixture steel belt clamping, steel band is tightened up with the contiguous block riveted with steel band and U-shaped piece, and nut coordinates with contiguous block
Use, rotating nut, pull contiguous block, steel band is tightened up.
Referring to Fig. 3, a kind of structural representation of side stand component of curved sheets quenching fixture one of the invention.The support
Frame branch panel products surplus, alignment pin coordinates with supporting plate, and positioning product, supporting plate both sides are two clamp systems, steel
Band compresses product surplus.Supporting plate side is equipped with suspension ring, hangs frock, and product immerses salt made from earth containing a comparatively high percentage of sodium chloride together with frock by big end
Groove, reduces the quenching distortion of product.
During curved sheets quenching fixture work of the present invention, its concrete operation step is as follows：
