Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the present invention is further described.
As shown in the figure, this periphery sanding apparatus comprises and is rotatably arranged at swivel mount 2 in frame 1 and two abrasive disc unit 3, one end of swivel mount 2 is the turning cylinder 21 be connected with drive motors, its other end bifurcated forms two symmetrical connecting plates 22, the relative side of two connecting plates is inside it, and opposite side is outside it, abrasive disc unit 3 comprises sliding axle 31, abrasive disc fixed mount 32, abrasive disc 33 and inertial mass 34, connecting plate 22, abrasive disc fixed mount 32 and abrasive disc 33 are provided with the connecting hole 35 of multiple correspondence, sliding axle 31 passes connecting hole and the two ends of this sliding axle are fixedly connected with abrasive disc fixed mount 32 with inertial mass 34 respectively, make abrasive disc fixed mount, inertial mass lays respectively at the inner side of connecting plate, outside, abrasive disc is fixedly installed in abrasive disc fixed mount, the quality of inertial mass is greater than abrasive disc and abrasive disc fixed mount sum, and can connect extra mass as required to increase the overall weight of inertial mass by screwed hole in the arranged outside of inertial mass, in order to ensure bonding strength, the sliding axle being plugged in symmetrical 2 connecting holes on connecting plate diagonal respectively by two between inertial mass with corresponding abrasive disc fixed mount connects, two abrasive disc unit 3 are symmetricly set on two connecting plates respectively, make the abrasive disc of two abrasive disc unit relatively and the working space formed between two abrasive discs periphery polishing, connected by resilient snubber between two abrasive disc unit 3.Because the centrifugal force that inertial mass when the present invention is by rotating is larger drives abrasive disc to polish to surface of the work, repeatedly rigid collision can be formed so arrange resilient snubber to the surface of workpiece due to gravity cause in order to prevent abrasive disc under low rate start state, concrete embodiment is as follows: be fixedly connected with fixed axis 38 between two connecting plates, the middle part of fixed axis is provided with thread segment.This thread segment is bolted with elastic force regulating block 39, elastic force regulating block 39 is connected with side abrasive disc by spring 37 i.e. described resilient snubber, and fixed axis, elastic force regulating block and spring have two groups and about the center of rotation symmetry of swivel mount.
The side that two abrasive disc fixed mounts 32 are relative has the link slot 321 of opening in opposite directions, and abrasive disc is fixedly installed in this link slot by bolt 322 and compress gasket 323, makes abrasive disc 33 can unclamp bolt in use for some time like this and changes in good time.
Abrasive disc 33 is provided with interior side opening stopper slot 331, this stopper slot is built-in with the positive stop strip 332 regulating it to stretch out stopper slot length by bolt, the length that this positive stop strip stretches out stopper slot can adjust according to allowance, and when grinding operation reaches requirement, two in fact mutual being maintained a certain distance by positive stop strip of abrasive disc are dallied at the outer surface of workpiece.Connecting hole 35 is built-in with sliding guide sleeve 36; sliding axle is slidably arranged in this sliding guide sleeve; in fact the lower material of hardness can be selected to make sliding guide sleeve; while protection is formed to sliding axle; also can change according to the abrasion condition of sliding guide sleeve in good time, in fact also form the protection to connecting plate.
Turning cylinder 21 is for having the hollow shaft of circular hole 25, and the both sides of swivel mount have the feed pipe 4, the discharge nozzle 5 that arrange with circular hole coaxial; The end that feed pipe, discharge nozzle are relative with working space is all connected with the clamping part for clamping workpiece; This clamping part is chuck 6, as needs, can select the automatic chuck being convenient to automatically control.The outer end of turning cylinder is provided with the bearing 23 and driving belt groove 24 that are connected with frame.
During operation, after chuck 6 is unclamped, from feed pipe, workpiece is pushed in the middle part of two chucks, then chuck is by Workpiece clamping, start the drive motors that swivel mount is corresponding, along with the raising of swivel mount rotating speed, inertial mass drives the abrasive disc fixed mount that is attached thereto and abrasive disc then to polish to excircle of workpiece to excircle of workpiece is close under the influence of centrifugal force; Polishing stock removal can control according to rotating speed and spring specification, when centrifugal force and spring force formed balance time polishing operation in fact stop.Certainly, for small workpiece, also can without clamping chuck, only suitably polish in the offhand feeding termination of station to workpiece.
The same side of two connecting plates extends in opposite directions, and this extension central rotatable is provided with gear 7; The both sides of gear are engaged with a spur rack 8 respectively, and one end of spur rack is fixedly connected with side inertial mass respectively by bolt 10, and its other end slides in the fairlead 9 on opposite side connecting plate; In order to strengthen the connective stability of spur rack, on bolt 10, cover has the fastening spring 101 be connected with connecting plate elasticity.The spur rack 8 that the present embodiment engages by being arranged at gear 7 in two inertial mass, keep two inertial mass symmetrical relative to the center of rotation of swivel mount, the shake that the gravity due to two inertial mass and abrasive disc and abrasive disc fixed mount self causes producing in rotary course can be avoided.
The present invention is rotated by the abrasive disc be arranged in abrasive disc fixed mount and polishes to the excircle of workpiece between two abrasive discs, and the depth of cut of abrasive disc is the accident that abrasive disc breakage is less likely to occur the gradual change amount formed under the rotating speed of swivel mount and the elastic force combination of spring; And abrasive disc is limited in swivel mount and abrasive disc fixed mount, and the metal fillings correspondingly produced in grinding process is also limited in respective range, safer.
