Description
Technical field
It the utility model is related to disc spring load adjustment technology field, more particularly to a kind of stretching of disc spring load adjustment bolt
Device.
Background technology
The stretcher of the existing special equipment for the adjustment of disc spring load is easily damaged bolt pair, and pulling force is not allowed
Really, it is inconvenient for operation.
Utility model content
A kind of the defects of the utility model aim is exactly to make up prior art, there is provided disc spring load adjustment bolt stretching
Device.
The utility model is achieved through the following technical solutions：
A kind of disc spring load adjustment bolt stretcher, includes manual pump, oil cylinder, core bar bolt, core bar nut, connection spiral shell
Mother, hanger bolt, hanging nut, cylindricality cushion block and disc spring group, piston is equipped with oil cylinder, through hole, core are provided with piston centre
Stem nut is spun on the top of core bar bolt, and the lower end of core bar bolt passes through the through hole of piston centre, and lower end passes through attaching nut
It is connected with the top of hanger bolt, on hanging nut rotation hanger bolt, cylindricality cushion block is sleeved on hanger bolt, cylindricality cushion block position
Below hanging nut, the disc spring group is spun on the bottom of hanger bolt, is equipped with pressure gauge on manual pump, pump is logical manually
The oil inlet for crossing oil pipe and oil cylinder connects.
Six square set rings are cased with outside hanging nut.
1st, locking nut is pulled down in the boiler hanging assembled.
2nd, attaching nut is spun on hanger bolt together with core bar bolt.
3rd, stretcher assembly set is put on column cushion block outside core bar bolt and hanging nut.
4th, core bar nut, packing ring are assembled by figure, and draws plane on cap to fit snugly against with bolt.
5th, L-HM46 is filled in hand oil pump fuel tank#Antiwear hydraulic oil.
6th, manual pump is connected with stretcher with high-pressure hose.
After charging handle on manual pump is screwed clockwise, compression bar is pressed repeatedly with hand, at this moment should be seen that：
1. the drawing cap of stretcher shifts up.
2. hanging nut has loosening with column cushion block.
3. gauge hand is begun to ramp up.
When pressure gauge is indicated to 3Mpa~5Mpa, unclamp the charging handle manually on pump and unloaded, then, then add
Pressure, is so repeated 2 times -3 times, to complete system exhaust work.
Note：
If 4. drawing cap to have creeping phenomenon to belong to normal around here, when exhaust work is completed, this phenomenon disappears.
5. exhaust work is critically important, otherwise system work will be unstable.
Life's work can be carried out after the completion of exhaust work, the charging handle manually on pump is locked, presses compression bar, and monitor
Reading on pressure gauge, at this moment hanging between nut and column cushion block has loosening, continues to press the compression bar on pump manually, pressure value
Rise, dished spring assembly is also constantly compressed, until after the indicated value of pressure gauge reaches the load value of setting, six sides are pulled with tommy bar
The lantern ring, makes hanging nut to bottom offset, untill abutting on column cushion block.
So far the load inversion of dished spring assembly/calibration is completed, and unclamps the charging handle manually on pump, downward turn core
Stem nut, will draw cap to push back original position, the fluid in oil cylinder flows back to fuel tank.
Pull down high-pressure hose, bolt tensioning jack and bracket component.
The utility model has the advantages that：The utility model utilizes the pulling force that hand oil pump produces, and acts on bolt, nut
Bottom can be easily rotated to, load inversion work is completed after stretcher unloading, and bolt pair is injury-free, pulling force is accurate.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model.
Embodiment
As shown in Figure 1, a kind of disc spring load adjustment bolt stretcher, includes pump 1, oil cylinder 2, core bar bolt 3, core manually
Stem nut 4, attaching nut 5, hanger bolt 6, hanging nut 7, cylindricality cushion block 8 and disc spring group 9, piston 10 is equipped with oil cylinder 2,
Through hole is provided with 10 center of piston, core bar nut 4 is spun on the top of core bar bolt 3, and the lower end of core bar bolt 3 is passed through in piston 10
The through hole of the heart, and lower end is connected by attaching nut 5 with the top of hanger bolt 6, hanging nut 7 is rotated on hanger bolt 6, column
Shape cushion block 8 is sleeved on hanger bolt 6, and for cylindricality cushion block 8 below hanging nut 7, the disc spring group 9 is spun on hanger bolt
6 bottom, is equipped with pressure gauge 11, pump 1 is connected by oil pipe 13 with the oil inlet of oil cylinder 2 manually on manual pump 1.
Six square set rings 12 are cased with 7 outside of hanging nut.
Claims (2)
