Brief description
Fig. 1 is the geophone magnet steel magnetic stepping device structural representation providing in this utility model embodiment.
In figure：1 workpiece placement rack；2 sucking heads；3 support bases；4 connecting bolts；5 measurement underframe；6 precision electronic balance.
Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely description is it is clear that described embodiment is only a part of embodiment of this utility model rather than whole
Embodiment.
With reference to Fig. 1, its geophone magnet steel magnetic stepping device providing for this utility model, this device includes measuring
Device and display device, described measurement apparatus include workpiece placement rack 1, sucking head 2, support base 3, connecting bolt 4 and measurement
Underframe 5, described display device is precision electronic balance 6, and the bottom of described workpiece placement rack 1 is hollow ring, to place
The magnet steel of geophone to be measured, depending on the diameter of magnet steel to be measured, described measurement underframe 5 sets the size of this circle diameter
Put the upper surface in precision electronic balance 6, the upper surface of described precision electronic balance 6 opens up a circular groove, this circle
Inside grooves surround a round platform, and this round platform is the gravity sensor of electronic balance, and the bottom of the described circle of measurement underframe 5 sets
Put on this round platform, described workpiece placement rack 1 is inverted U-shaped structure, described measurement underframe 5 is just U-shaped, the two side is even
Connect, and opposite side be not connected with, its place of being not connected with is passed through by described support base 3, described support base 3 stretch into workpiece placement rack
One end of 1 bottom, its upper surface arranges sucking head 2, and the other end of described support base 3 is connected to institute by connecting bolt 4
On the housing of precision electronic balance 6 stated, the side being connected with workpiece placement rack 1 of described measurement underframe 5, by connection spiral shell
Bolt 4 is connected on the described housing of precision electronic balance 6.Described measurement underframe 5 and workpiece placement rack 1 are positioned over accurate electricity
Concentric position is kept on the round platform of the gravity sensor of sub- balance and with sucking head 2.
Described workpiece placement rack 1, support base 3, connecting bolt 4 and measurement underframe 5 are non-magnetic material processing and fabricating, that is,
Magnet steel will not be produced and attract；Described sucking head 2 adopts special soft magnetic materials to make, and can produce the same of attraction to magnet steel
When will not be magnetized by the magnetic field of magnet steel again.The magnetic of the magnet steel of geophone to be measured is bigger, and it is strong to the attraction of sucking head 2
Degree is stronger, and magnet steel is converted into gravity value to the sucting strength of sucking head 2 by the weight sensor using electronic balance, according to gravity
The size of value, thus judging the power of magnet steel magnetic, is finally completed the work of magnet steel stepping.
The work process of geophone magnet steel magnetic stepping device described in the utility model：
First electronic balance is placed steadily, then balance is adjusted to by level by the level indicator on balance, opens afterwards
Balance is simultaneously reset by balance on and off switch, magnetic magnet steel to be measured will be carried vertically to be placed on workpiece placement rack, when balance number
After value stabilization, read the numerical value on balance.The bigger sucting strength to sucking head of magnet steel magnetic is bigger, and balance reading is also more
Greatly.Size according to balance numerical value judging the size of magnet steel magnetic, thus magnet steel is carried out with the stepping of magnetic.
