Specific embodiment
Be described further below the technical solution of the utility model, but claimed scope be not limited to it is described.
As shown in Figures 1 to 4, a kind of fixture of ring-shaped work pieces nitridation described in the utility model, including pallet 1, framework
Pillar 2 and cross 3, are provided with some fixed pin jacks 21 on the post setting 2, if being that dried layer is arranged on the pallet 1
Frame pillar 2, every layer of pallet 1 is installed on the correspondence position of fixed pin jack 21, and passes through fixed pin jack 21 to consolidate by steady pin
Fixed, the activity of the cross 3 is placed on pallet 1.Using the technical program, disposably 20 annulars of clamping parts 4 can be nitrogenized
It is even more many, production efficiency is greatly improved, reduce production cost；Convenient dismounting and replacing simultaneously.
A diameter of 50mm~70mm of the frame pillar 2, is highly 800mm~1000mm.With well formula when specifically used
It is highly consistent that nitriding furnace effectively heats qualified area.
Several are provided with the frame pillar 2 and fix pin jack 21.Fixed pin jack 21 is used to be fixed on pallet 1
On frame pillar 2, its dead bolt bore in the technical program, is provided with 5 fixed pin jacks on the frame pillar 2
21, that is, 5 layers of pallet are placed, wherein, the distance between jack 21 of each steady pin is 150mm~180mm, and first jack
It is 40~60mm apart from the distance from bottom of frame pillar 2.A diameter of 12mm~12.5mm of the fixed pin jack 21.Using above-mentioned
Arrangement spacing, is conducive to nitriding atmosphere to circulate.
A diameter of 12mm of the steady pin.When pallet 1 is installed, insert 12mm's on the jack of each steady pin
Steady pin, then supporting plate is placed on above, play spacing pallet effect.
The upper end of the frame pillar 2 is provided with I-shaped draw-in groove 22, and the height of I-shaped draw-in groove 22 is 20mm, a diameter of
35mm~55mm；I-shaped draw-in groove 22 is used for suspender hook card.
The pallet 1 is made up of stainless steel flat plate, and some air-vents 11 have been evenly arranged on stainless steel flat plate.
The thickness of the stainless steel flat plate is 5mm.Can prevent from rear pallet 1 is used for multiple times and deform, damage；The pallet 1 is straight
Footpath is 620mm, and it is consistent effectively to heat qualified area's diameter with well formula nitriding furnace.
The arrangement of the air-vent 11 is from the center of whole pallet 1 to external diffusion, in the diameter circumference every 100mm
On be evenly arranged.So as to the circulation of nitriding atmosphere, depending on the size of empty quantity according to pallet 1, air-vent in the technical program
11 a diameter of 23mm, has 131 air-vents.Also it is evenly arranged by 4 through holes near outer inner round side on the pallet 1, is led to
Bore dia is (50~70)+2 0Mm, is taken for wearing for frame pillar 2, and after being used for multiple times, the pallet 1 of damage can be changed,
It is easy to operate, can continue cycling through and use；The through hole that frame pillar 2 is taken for wearing is located at the outside of outermost air-vent 11；
In the technical program, the through hole that frame pillar 2 is taken for wearing is located at the circumference of a diameter of 600mm.
The cross 3 is made up of two boards interconnection.The length of every block of plate is 180mm~220mm, is highly
32mm~35mm, this highly must be higher than the height of annular nitridation part 4, and thickness is 5mm, every piece of centre of plate length direction
Position is provided with depth for 16mm~17mm, and width is the notch 31 of 15mm~16mm, and two boards intersect to form a cross 3.
It is not influence nitriding result because annular nitridation accessory size is larger, 2 annular nitridation parts 4 can only be put on every layer of pallet 1.
Because shelf is higher than annular nitridation part 4, can be placed on pallet 1 with cross 3, then annular nitridation part 4 is placed on ten
On cabinet frame 3, the part on shelf does not influence nitriding result, while increasing batch higher than the part on pallet 1.
The frame pillar 2 is made of seepage resistant material.The seepage resistant material uses Inconel600 materials；
1Cr18Ni9Ti stainless steels are difficult nitriding, and dismountable pallet 1 and cross 3 are done from stainless steel, and it is convenient to be changed after damage.
