Above-mentioned 7 outer wall of the ontology seat of honour is cylindrical type, and buffer system includes pressure regulation slide valve 24, and pressure regulation slide valve 24 is that section is C
Type arc-shaped, the tubular structure that is pivotally sleeved on 7 outer wall of the ontology seat of honour, the position of low pressure buffer chamber 7b is corresponding to adjust
The position of slide valve 24 is pressed, the ontology seat of honour 7 is equipped with multiple relief hole 7e along its axial alignment for straight line row, pressure regulation slide valve 24
It is equipped with a pressure release strip-shaped hole 24a extended spirally, the width of pressure release strip-shaped hole 24a and the aperture of single relief hole 7e are mutually fitted
Match, pressure release strip-shaped hole 24a is selectively connected to one of relief hole 7e, and relief hole 7e is connected and makes with telescopic movable chamber 7a
Used time low pressure buffer chamber 7b corresponding part relief hole 7e.
During the test, buffer system has the function of two sections of adjustable rigidities: where the first cushion rigidity is by low pressure buffer
The characteristic of chamber 7b determined, the relatively rotation place of pressure regulation slide valve 24 and the ontology seat of honour 7 is adjusted so that pressure release strip-shaped hole 24a and
Relief hole 7e is selectively connected to, thus it is possible to vary effective swept volume in low pressure buffer chamber 7b, to complete buffering course rigidity
Adjusting；When needing to tune up the first cushion rigidity, pressure regulation slide valve can be rotated (from 7 tail portion forward direction of the ontology seat of honour) clockwise
24, it is corresponding with the relief hole 7e of rearmost end to make pressure release strip-shaped hole 24a, and pressure regulation slide valve 24 shelters from all relief holes in front
7e, therefore during the Forward of main slide bar 3, sealing state can be constituted by the relief hole 7e that pressure regulation slide valve 24 shelters from, thus
Increase effective swept volume in low pressure buffer chamber 7b；When needing to turn the first cushion rigidity down, it is sliding that pressure regulation can be rotated counterclockwise
It is corresponding with the relief hole 7e of front end to make pressure release strip-shaped hole 24a for valve 24, so that the effective work reduced in low pressure buffer chamber 7b is held
Product.
Above-mentioned buffer system includes regulator valve 11, and the second cushion rigidity can pass through the pressure regulation to high-pressure buffer chamber 7c
It realizes, the air pressure of high-pressure buffer chamber 7c is regulated and controled using regulator valve 11, regulator valve 11 is inserted into the ontology seat of honour 7
On, and the corresponding high-pressure buffer chamber 7c of regulator valve 11 and the air pressure for adjusting high-pressure buffer chamber 7c.Wherein, low pressure buffer chamber
The adjusting operation of the compensator or trimmer pressure of 7b is completed by adjusting the position of pressure regulation slide valve 24；The air pressure of high-pressure buffer chamber 7c passes through tune
Pressure safety valve 11 is adjusted, and in the case where high-pressure buffer chamber 7c inner overpressure, can run through regulator valve 11 and put
Excessive gas out, to guarantee the safety of use process.The effect of buffer system is to guarantee hammering head 1 in impact measured workpiece
Afterwards, can flexible buffer and returning quickly, so that preventing from double-clicking workpiece influences measuring accuracy, and guarantee under extreme conditions
The safety of (such as hot environment) high-pressure buffer chamber 7c.
Above-mentioned telescopic movable chamber 7a inner wall is equipped with one and enclose defining flange 7f for limiting 10 position of piston separator, separates work
Plug 10 is between drive end bearing bracket 9 and defining flange 7f.
Above-mentioned main slide bar 3 faces one section of manipulatable end equipped with the scale marker for being used to indicate 6 precompressed amount of energy-storaging spring.So as to standard
Really judge the precompressed amount of energy-storaging spring 6.
Specific workflow is as follows:
(S1) prepare link: according to specific test object, respectively to 2 range of acceleration transducer, hammering 1 rigidity of head, storage
All parameters such as 6 precompressed amount of energy spring, low pressure buffer chamber 7b pressure and high-pressure buffer chamber 7c pressure are chosen, and can be according to individual
The difference of use habit, adjust trigger 16 pulls the angle position buckle 16a, turns adjustment bolt 22, is supported using adjustment bolt 22
Drive entire trigger 16 to carry out the fine tuning in angle by the conflict inclined-plane 16f of forward extension 16b, with adapt to different operation person's
Operating habit；
(S2) accumulation of energy link: according to specific test request, more appropriate 6 precompressed dynamics of energy-storaging spring is selected, will be operated
Handle 4 pulls back, until the scale marker for being used to indicate spring precompressed amount on main slide bar 3 reaches setting value；At this point, resistance iron 17
One of tooth socket 5b of flank of tooth sliding block 5 is moved up and resisted under the promotion of reset spring 19, thus the main slide bar 3 of locking, meanwhile,
During main slide bar 3 moves back, air enters low pressure buffer chamber 7b by relief hole 7e；
(S3) the pressure governing loop of high-pressure buffer chamber 7c, low pressure buffer chamber 7b: rotating pressure regulation slide valve 24 along axial position,
Cooperate pressure release strip-shaped hole 24a and bleeder port 7e, thus by adjusting low pressure buffer chamber 7b dischargeable capacity to its cushion rigidity
It is adjusted；Meanwhile passing through the air pressure in the adjustment of regulator valve 11 high-pressure buffer chamber 7c using inflatable tool；
(S4) exciting link: user holds hand holding handle 21, and release mechanism 23 is pushed forward, so that locking pearl 23d is inserted
Enter forward safety groove 23e, to release the locking to trigger 16.Positioning ring 12 is resisted against measured workpiece surface (to pay attention to not
Force into measured workpiece), cocking 16, at this point, trigger 16 drives resistance iron 17 to overcome the elastic force of reset spring 19 downward
Mobile, so that locking hook part 17a is detached from the tooth socket 5b of flank of tooth sliding block 5, main slide bar 3 is under the elastic force effect of energy-storaging spring 6, forward
It is mobile, and acceleration transducer 2 and hammering head 1 is driven to impact measured workpiece, complete exciting；
(S5) link is buffered: when main 3 propulsion of slide bar, compression and low pressure cushion chamber 7b, with the Forward of main slide bar 3,
Gas pressure increases continuously until that low pressure buffer chamber 7b pressure is equal with high-pressure buffer chamber 7c pressure in low pressure buffer chamber 7b, at this time
10 forward movement of piston separator compresses the gas in high-pressure buffer chamber 7c, thus after guaranteeing that main slide bar 3 reaches forward setting displacement
Quick rebound can be mildly carried out, an exciting test process is completed；
Meanwhile compressed gas is filled in the rod chamber of positioning ring cylinder 13 by venting channels 15 in low pressure buffer chamber 7b,
To drive the elastic force of spring 14 built in the piston overpowers of positioning ring cylinder 13 and rearward move, driving positioning ring 12 leaves tested
The surface of workpiece prevents positioning ring 12 from contacting measured workpiece and influencing test result.
If you need to repeat exciting vibration, then link S2 is repeated to link S5.
It is the preferred embodiment of the present invention above, those of ordinary skill in the art can also carry out various changes on this basis
It changes or improves, under the premise of not departing from the present invention total design, these transformation or improve all should belong to that the present invention claims guarantors
Within the scope of shield.
