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 not yet popularized, and in part producing and research project, the effect of autogenous mill is not yet
Fully up to expectations, therefore, in many war industry's units and colleges and universities, still using the method for hand lapping, there is an urgent need for one kind to improve
The milling tool of process safety.
The content of the invention
For overcome the deficiencies in the prior art or defect, the present invention proposes a kind of with cushioning effect and force measuring function
Hand-ground rod, improves the safety of grinding process.
Grinding rod provided by the invention, including sleeve, hollow cylinder, grinding rod core, rubber ring, dynamometer spring, graduated scale,
Base.
It is cylinder inside the stack shell of sleeve, adequate operation person grasps.Stack shell top is arc-shaped, and has circle on top
Perforate.Hollow cylinder is connected with base by dynamometer spring, and grinding rod core is fixed in base one end, and graduated scale is fixed in one end.Scale
Ruler passes through hollow cylinder, is stretched out by the perforate of sleeve top.
Hollow cylinder top is close with sleeve top but does not contact, and the stack shell of hollow cylinder is close to top and the portion of bottom
It is divided to and is fixed by two rubber rings with sleeve lining, fixed form can be that gluing or squash type is fixed.Wherein close to sleeve top
The elasticity modulus of the rubber ring at end is more than another rubber ring.
The grinding rod core material is agate or ceramics, is fixed in the centre bore for the base that its top is placed in.
The dynamometer spring for compression spring, its outside diameter with hollow cylinder, base outside diameter it is identical；Both ends of the spring is solid respectively
It is scheduled on hollow cylinder bottom and base top.
The graduated scale is cylinder, its outside diameter is less than hollow cylinder internal diameter, and surface, which has, represents grinding rod core stress size
Scale.
Scale surface scale is the indicated value of uprighting spring pressure.Scale surface also can be successively from top to bottom
Green, yellow, red three kinds of instructions color.
Application method：
When in use, operator holds grinding rod sleeve to the grinding rod, can exert oneself in sleeve vertical direction, sleeve passes through rubber
Rubber ring, dynamometer spring, be finally conducted to grinding rod core, abrasive material compressed and rubbed against so as to fulfill grinding rod core.Operation
When vertical direction progressively reinforces, dynamometer spring deforms upon person, and the hollow cylinder that sleeve drives moves downward, at the top of sleeve
Graduated scale scale respective change, shows current grinding strength.
When operator grinds rotation in the horizontal direction using grinding rod, the sleeve of grinding rod and between rubber ring meeting
The a degree of deformation of generation, objectively there is certain buffering effect.
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.
Rubber ring and dynamometer spring of the present invention between sleeve and grinding rod core so that the power of operator when in use
Degree and speed increase have an obvious buffering course, significantly enhance the controllability that operator operates grinding rod.
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.
