Description
Technical field
The present invention relates to a kind of grinding rods, the grinding process suitable for priming system industry and energetic material research.
Background technique
Dangerous chemicals produce and study in, in order to meet technique 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.When hand-ground priming system, abrasive power, which spends big, excessive velocities, all may 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.It visits to find out its cause, it is not difficult to find that due to lacking the understanding to processing sample, grinding rate, particularly the standard for grinding dynamics
Really, it getting information about, prolonged grinding operation causes operator to judge dynamics, the speed of grinding operation by accident, thus
Result in the generation of accident.
Caused industrial accident is ground in chemicals industry in order to reduce, the country has 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, the method for still using hand lapping, need a kind of milling tool that process safety can be improved.
Summary of the invention
For overcome the deficiencies in the prior art or defect, the present invention propose that one kind has buffer function and dynamics instruction effect
The hand-ground stick 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 be bottom opening cylindric cylinder, stack shell top be it is hemispherical, there is circular hole at top center；Stack shell surface
There are 2 limiting slots, the screw rod that limiting slot is connected about bushing core axial symmetry, by the fender pile of sleeve inner is up and down to be mentioned
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 fender pile movable
Range is excessive, and annular diameters are 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；It buffers logical in the middle part of stick body
It crosses symmetrical threaded hole and 2 Limit screws is installed, the Limit screw other end both passes through limiting slot, and screw diameter is less than limit groove width
Degree, when length is contacted with fender pile and limit baffle ring, subject to the still extended limiting slot of Limit screw；Buffering is cased on Limit screw
Spring, buffer spring outer diameter are greater than limit groove width；
At the top of fender pile and bottom centre is fluted, and top groove is fixed with graduated scale, is cased with dynamometer spring on graduated scale,
The outer diameter of dynamometer spring is greater than bore dia at the top of sleeve, and graduated scale end is stretched out by sleeve top circular hole；Fender pile bottom is recessed
Slot is fixed with grinding rod core, and the material of grinding rod core is agate or ceramics, and end is grinding bulb；
When Limit screw is located at limiting slot bottom, graduated scale end can stretch out sleeve；When Limit screw is located at limit
When the slot 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 can also 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 dynamometer spring and buffer spring by sleeve, is finally conducted to grinding rod core,
To realize that grinding rod core compresses and rubs against abrasive material.
When operator holds grinding rod sleeve, and the grinding bulb of grinding rod core is not contacted with mortar or grinding material, limit
Position screw rod is located at limiting slot lower end.After grinding rod core and mortar or grinding material contact, operator gradually adds in vertical direction
When power, deformation occurs for dynamometer spring, 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
It will failure.Similarly, when touching on the outside of fender pile on the inside of limit baffle ring, operator continues to increase power in gag lever post direction
Degree, buffer function of the grinding rod in Limit screw direction will fail.
Operator, should be slow in one's movements as far as possible during using present apparatus grinding explosive wastewater and energetic material, and is grinding
The graduated scale indicating value for paying close attention to grinding rod always in the process, by grinding dynamics control in the range of safe and reasonable.
The invention has the advantages that
It is all that the grinding dynamics of grinding rod is controlled with feeling by experience when operator is using common grinding stick, it is fried in fire
In medicine industry, this milling tool when in use, inevitably has 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 apparent warning and indicative function.In conjunction with the understanding to ground sample, operator can be incited somebody to action
Grinding dynamics controls in safe range.The real-time display of top of grinding rod graduated scale indicating value is also avoided that operator longer
In the process of lapping of time, it is not intended to due to grinding dynamics caused by attention-deficient or itself subjective erroneous judgement to grinding dynamics
Safety accident 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 apparent 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.
