Abstract
The invention relates to a broadband type sanding grinder sanding head upper roller rigid middle shaft structure comprising an upper beam, a middle beam, a cylinder and a sanding rack. The connection between the middle shaft and the piston pole of the cylinder is a steel ball, a middle shaft sleeve hole is disposed on the sanding hole, the piston pole of the cylinder is disposed in the middle shaft sleeve hole and is fixed on the sanding rack, a shaft sleeve is inlaid in the middle sleeve hole, the piston pole of the cylinder is disposed in the shaft sleeve, the middle shaft is sleeved in the shaft sleeve, the upper end surface of the middle shaft is connected with the upper beam, the lower end surface thereof forms a universal jointing construction with the upper end terminal of the cylinder piston pole by the steel ball. The advantages of the invention are: firstly, solving the seesaw activation of the upper beam in Y axis direction presenting in background art radically, preventing incontrollable deflection and folding of the sanding belts; secondly, the sanding belts are controlled not to flee in certain time so that workpieces on which snakelike lines can't be present are machined; thirdly, since the lift cylinder and the middle shaft are designed separately, the service life of the cylinder is elongated greatly.
Description
Technical field
The present invention relates to axle construction in a kind of broadband type abrasive finishing machine abrasive finishing head upper roller rigid, belong to wide-belt sander and make the field.
Background technology
Existing broadband type abrasive finishing machine abrasive finishing head upper roller structure is: 1, putting the beams in place directly is connected with the piston rod of cylinder.Its weak point is: because the vertical stability of piston rod support is piston bush, and piston bush stable plunger bar do not produce along teetertotter (seesaw movement) of Y direction derive from all cylinder itself the load that can carry, after the value that the piston rod bearing load sets greater than it, its piston bush just can't the stable plunger bar and piston bush between produced rock (as seesaw, rocking up and down especially), produce the gap between the two, As time goes on, this gap is increasing, and the rolling momentum that the upper beam Y direction is produced is also increasing.In background technology, because being not only of piston rod carrying put the beams in place and last deflector roll weight, produce uncertain active force in the grinding motion but also be included in, its load is the required value of piston bush stable plunger bar head and shoulders above, not only causing piston rod is that axis produces teetertottering of Y direction inevitably, this rocks and makes the abrasive band that is arranged on the deflector roll revolve in the high speed commentaries on classics, abrasive band sideslip, folded band, directly have influence on quality and abrasive band service life of sanding, and directly cause the cylinder lost of life.2, because cylinder piston rod (being axis) should play the effect in lifting tensioning abrasive band, make Z again to the control band function of rotating, so that the sealing of cylinder can't effectively be guaranteed, cylinder is reduced service life greatly.
Summary of the invention
Purpose of design: avoid the weak point in the background technology, design a kind of have enough abrasive band tensioning dynamics and stroke, guarantee that idler roller can not produce teetertotter (seesaw movement) of Y direction, and can satisfy the idler roller Z-direction sanding head of swing flexibly, and can avoid the weak point in the background technology effectively, make reach the longest the service life of cylinder, very convenient in the maintenance.
Design: in order to realize above-mentioned purpose of design.1, fixedly connected with upper beam in the axis upper end, is one of feature of the present invention.Axis and two parts of lift cylinder for separating fully, the connection between the two realizes by steel ball.Fixedlying connected with upper beam in the axis upper end, does not exist any of all directions to rock.2, bottom bracket axle edge spheroidal graphite cast-iron bearing shell or tin bronze bearing shell in bottom bracket axle, in the axle sleeve is two of feature of the present invention.Because bottom bracket axle of the present invention is with the sand frame and fixedlys connected, that is to say, do not produce any rocking between axle sleeve and the sand frame, and the axis that is arranged in bottom bracket axle spheroidal graphite cast-iron bearing shell or tin bronze bearing shell is retrained by bottom bracket axle and spheroidal graphite cast-iron bearing shell or tin bronze bearing shell, and axis and bearing shell are a kind of interference fits, axis is under the effect of external force, can only Y direction move both vertically and the Z-direction rotation, the axis of fundamentally having avoided background technology to exist is lifted up the defective of rocking up and down along Y direction, has solved owing to last deflector roll rocks the abrasive band sideslip that causes, technological deficiencies such as folded band.3, adopting steel ball to be connected between axis lower end and cylinder piston rod end surface, is three of feature of the present invention.What axis lower surface and cylinder piston rod end surface employing steel ball were connected to form is universal structure, because the lower surface of axis and the upper surface of cylinder piston all are positioned at bottom bracket axle, steel ball is placed between these both ends of the surface, just especially as make and constituted a gimbal structure that can only move along Y-axis and Z-direction between axis and cylinder piston, both satisfied the requirement that axis moves both vertically along Y-axis, it is quite little, very flexible along the requirement and the rotary resistance of Z-direction rotation to have satisfied axis again.
Technical scheme: axle construction in the broadband type abrasive finishing machine abrasive finishing head upper roller rigid, it comprises upper beam (1), axis (2), cylinder (5) and sand frame (6), be connected to steel ball (4) between the piston rod of axis (2) and cylinder (5), sand frame (6) has the axis trepanning, piston rod in the cylinder (5) is positioned at the axis trepanning and cylinder (5) is fixed on the sand frame (6), it is characterized in that: stud with axle sleeve (3) in the axis trepanning, the piston rod of cylinder (5) is positioned at axle sleeve, axis (2) is enclosed within the axle sleeve (3), and the upper surface of its axis (2) is connected with upper beam (1), the lower surface forms universal syndeton by the upper surface of steel ball (4) and cylinder (5) piston rod.
The present invention compares with background technology, and the one, fundamentally solved the upper beam Y direction seesaw action that background technology exists, stopped the folded band in the out of control and abrasive band of abrasive band sideslip; The 2nd, can keep the not play control band in abrasive band within a certain period of time, some can not have the workpiece of snake track thereby reach processing; The 3rd, owing to adopt lift cylinder and the design of axis separate type, thus greatly improve the service life and the convenient for maintaining of cylinder.
