Description
Technical field
The present invention relates to a kind of grinding rod, the grinding process suitable for priming system industry and energetic material research.
Background technology
Dangerous chemicals produce and study in, in order to meet technological requirement, it is often necessary to by solid material crush or
Person's grind into powder improves chemical reaction velocity to increase its contact area.In explosive wastewater industry, the grinding of energetic material is
One extremely dangerous process.During hand-ground priming system, abrasive power, which spends big, excessive velocities, may all cause burning or quick-fried
The generation of fried accident.In recent years, the quickening of explosive wastewater industry research speed, because industrial accident caused by grinding is sent out repeatedly
It is raw.Visit to find out its cause, it is not difficult to find that due to understanding of the shortage to processing sample, the standard of grinding rate, particularly grinding dynamics
Really, getting information about, prolonged grinding operation causes operating personnel to judge dynamics, the speed of grinding operation by accident, so that
It result in the generation of accident.
In order to reduce industrial accident caused by grinding in chemicals industry, the country have developed a variety of automatic grindings
Machine.However, since autogenous mill is in part producing and research project, effect is also not fully up to expectations, therefore, in many war industries
Unit and colleges and universities, still using the method for hand lapping, there is an urgent need for a kind of milling tool that can improve process safety.
The content of the invention
For overcome the deficiencies in the prior art or defect, the present invention proposes that one kind has cushioning effect and dynamics instruction effect
The hand-ground rod of fruit, improves the safety of grinding process.
Grinding rod provided by the invention, including sleeve, grinding rod core, fender pile, buffer spring, dynamometer spring, graduated scale,
Limit baffle ring and Limit screw.
The sleeve is the cylindric cylinder of bottom opening, and stack shell top is hemispherical, and there is circular hole at top center；Stack shell surface
There are 2 limiting slots, limiting slot is carried on bushing core axial symmetry, by screw rod that the fender pile of sleeve inner connects is up and down
For space, the limit baffle ring of sleeve bottom and circular ring shape is fixed by screw；The purpose of limit baffle ring is to prevent that fender pile is movable
Scope is excessive, its annular diameters is slightly larger than fender pile diameter, and it can be made free to rotate in ring.
The fender pile is cylinder, and top is stretched out in sleeve inner, lower end from limit baffle ring；Buffer logical in the middle part of stick body
Cross symmetrical threaded hole and 2 Limit screws are installed, the Limit screw other end both passes through limiting slot, and screw diameter is less than spacing groove width
Degree, when length is contacted with fender pile with limit baffle ring, subject to the still extended limiting slot of Limit screw；It is cased with buffering on Limit screw
Spring, buffer spring outside diameter are more than spacing well width；
At the top of fender pile and bottom centre is fluted, and top groove is fixed with graduated scale, and dynamometer spring is cased with graduated scale,
The outside diameter of dynamometer spring is more than bore dia at the top of sleeve, and graduated scale termination is stretched out by sleeve top circular hole；Fender pile bottom is recessed
Groove is fixed with grinding rod core, and the material of grinding rod core is agate or ceramics, its termination is grinding bulb；
When Limit screw is located at limiting slot bottom, graduated scale termination can stretch out sleeve；When Limit screw is positioned at limit
During the groove upper end of position, fender pile bottom can stretch out limit baffle ring.
Scale surface scale is the indicated value of dynamometer spring pressure.Scale surface also can be successively from top to bottom
Green, yellow, red three kinds of instructions color, firmly size is warned by color.
Application method：
When in use, operator holds grinding rod sleeve to the grinding rod, can be in sleeve vertical direction and along Limit screw
Rectilinear direction is exerted oneself, and power is conducted to fender pile by sleeve by dynamometer spring and buffer spring, is finally conducted to grinding rod core,
Abrasive material is compressed and rubbed against so as to fulfill grinding rod core.
When operator holds grinding rod sleeve, and the grinding bulb of grinding rod core does not contact with mortar or grinding material, limit
Position screw rod is located at limiting slot lower end.After grinding rod core is contacted with mortar or grinding material, operator progressively adds in vertical direction
During power, dynamometer spring deforms upon, and for Limit screw to movement above limiting slot, graduated scale shows current grinding strength.
After Limit screw is moved to limiting slot the top, operator continues increase dynamics, the indicative function of graduated scale
Will failure.Similarly, when the contact outside of fender pile is to limit baffle ring inner side, operator continues to increase power in gag lever post direction
Degree, cushioning effect of the grinding rod in Limit screw direction will fail.
Operator, should be as far as possible slow in one's movements during using present apparatus grinding explosive wastewater and energetic material, and is grinding
During pay close attention to the graduated scale indicating value of grinding rod all the time, by grinding dynamics control in the range of safe and reasonable.
Advantage of the present invention：
All it is that the grinding dynamics of grinding rod is controlled with feeling by experience when operator is using common grinding rod, it is fried in fire
In medicine industry, this milling tool when in use, inevitably with potential security risk and risk.It is proposed by the invention
Grinding rod by the dynamics of grinding it is this before the key parameter that can only hold by feel, being converted to the obvious of grinding rod top can
The graduated scale scale seen, can play obvious warning and indicative function.With reference to the understanding to ground sample, operator can incite somebody to action
Grinding dynamics is controlled in safe range.The real-time display of graduated scale indicating value, is also avoided that operator longer at the top of grinding rod
In the process of lapping of time, grinding dynamics is not intended to caused by attention-deficient or itself subjective erroneous judgement to grinding dynamics
Security incident caused by the increase of knowledge.
Groups of springs design of the present invention between sleeve and grinding rod core so that the dynamics and speed of operator when in use
Increase has an obvious buffering course, significantly enhances the controllability that operator operates grinding rod.On the other hand, on sleeve
Limiting slot and the limit baffle ring of bottom also define the compression zone of buffer spring and dynamometer spring, limit operator's use and grind
The dynamics upper limit on frotton, also provides a degree of safety guarantee.
During current explosive wastewater industry development, inevitably there is the danger for much needing operator's hand-ground
Product raw material and semi-finished product.The application of the invention can provide reliable safety guarantee for operator, reduce the general of explosion accident generation
Rate.
