Description

The grinding pressure control device of diamond abrasive intelligent robot
Technical field
The present invention relates to diamond technical field of processing equipment, a kind of grinding for diamond abrasive intelligent robot is specifically related to Mill pressure control device.
Background technology
It is processed into the diamond referred to as diamond of jewellery.There are various flaws on the crystal face of natural diamond crystal, in crystal Also can there are bubble, crackle, breach and other flaws in portion.For being processed into the rough diamond of ornaments, designed by decomposing scheme, divided After the operations such as the grinding and polishing in solution (split, saw or be cut by laser), wagon drill (edging line), corase grind (grinding core), table top and valve face Diamond finished product-jewellery could be turned into bore.
Abrasive drilling (grinding and polishing) is operation the most complicated, the most key during diamond is processed.In order to do to the limit Ground represents the optical characteristics of diamond, and modern diamond cut is designed as magnificent type cut, generally refers to the magnificent type of standard work Round bur.The reflection and refraction of table top and each valve face that light passes through the type finished diamond, can make " the going out fire " of diamond and gloss Optimum degree is reached, the natural beauty of diamond crystal is played incisively and vividly.
The shape of chiseling of magnificent type round bur is made up of middle part sideline, face and bottom.Face is except perpendicular to diamond centers line There are 32 valve faces into three circle arrangements outside table top, be referred to as valvula (16), main lobe (8) and star valve (8).This three circle The geometric molding in valve face is the how equilateral pyramid of three different cone angles and different faces number.24 valve faces into two circle rows are arranged at bottom Row, are referred to as bottom valvula (16) and bottom main lobe (8).The geometric molding in this two circles valve face is also two different cone angles and not The pyramid of coplanar number.Bottom main lobe is finally all converged to a bit, referred to as the vertex (vertices) of finished diamond.
Abrasive drilling operation seeks to perfect realize above-mentioned chiseling shape.The fixture of machine of the invention can be adjusted out and different inclined Angle, and 57 faces of finished product brill around the axis automatic indexing of itself, can be accurately ground by process.The formation problems that finished product is bored After solution, key is to improve the production efficiency of abrasive drilling.The efficiency of abrasive drilling can be described with abrasive drilling intensity, i.e. the unit interval Interior rough diamond top layer removal amount.
The factor of grinding intensity is influenceed to be mainly following four:1, speed of grinding plate rotating speed is higher, and the grinding intensity of diamond is got over Greatly;2, unit pressure increases diamond and the pressure of mill contact band can increase the stock removal of diamond, but unit pressure crosses conference very Diamond micro mist is wiped off soon, and accelerates the abrasion of mill, or even rupture diamond;3, coating of the diamond micro mist in mill working face Diamond micro mist particulate specification increases grinding intensity increase, but finish can be deteriorated, micro mist coating density abrasive drilling within the specific limits Efficiency highest, this respect have accumulated rich experience data;4, the orientation of grinding.
Therefore, for first in aforementioned four factor, we have incited somebody to action in supporting bench drilling burrstone mill of the invention Speed of grinding plate is increased substantially.This is reached by fine dynamic balancing technique and variable-frequency driving technique.The present invention will be to 2nd, compressive load per unit area during 4 two factors, i.e. abrasive drilling and the aspect of grinding orientation two implement intelligent solution.
The crystal structure of diamond causes the anisotropy of its hardness.The position of veil must be found during grinding, and brill Stone is positioned along the minimum direction of hardness, could produce highest grinding intensity.Rotation driving aligning device of the invention is continuous Change direction during intelligent decision preferential orientation, give and position.And by a set of automatic change in grinding process The mechanism regulation grinding force , And of spring tension produce optimum pressure value of the workpiece to mill by intelligent decision.
Thus, it is contemplated that the life of shape accuracy, grinding surface quality and grinding is chiseled in the perfect grinding for solving finished product brill Efficiency is produced, in the hope of reaching the economic benefit of maximum.
The content of the invention
The purpose of the present invention is exactly that the one kind provided to solve the deficiency of prior art can significantly improve production efficiency, And the grinding pressure control device of the diamond abrasive intelligent robot of reliable in quality.
The present invention is to realize above-mentioned purpose using following technical solution:A kind of diamond abrasive intelligent robot grinds Mill pressure control device, it is characterised in that it includes controller and with diamond abrasive intelligent robot for installing grinding work Make the elastic supporting mechanism that the slider assembly support of head coordinates, elastic supporting mechanism includes that the motor being arranged on base is installed Seat, stepper motor, eccentric wheel, extension spring, spring adjustment screw, parallel bar, parallel bar fixed seat, controller connection control step Stepper motor;One end of parallel bar is hinged with parallel bar fixed seat, and motor mount is fixed on base, and stepper motor is fixed on electricity In machine mounting seat, eccentric wheel is connected on the output shaft of stepper motor, and one end of extension spring is connected with eccentric wheel, and the other end leads to Spring adjustment screw is crossed to be connected with the other end of parallel bar;Plain thrust bearing and parallel bar top pressure are provided with work head assembly Coordinate;The self gravitation of mechanism's part is offset using spring tension, using the residual gravity after counteracting as grinding pressure, is led to Cross the adjustment that stepper motor connecting eccentric wheel control spring elongation length realizes grinding pressure.
As further illustrating for such scheme, be provided with eccentric rod on the eccentric wheel, one end of extension spring with Eccentric rod is connected, and the other end is connected on parallel bar by spring adjustment screw.
Further, the armature spindle of stepper motor is horizontally disposed with.
