Description

A kind of active drive lapping device
Technical field
The invention belongs to the lapping device field, be specifically related to a kind of active drive lapping device.
Background technology
Grinder is of a great variety both at home and abroad, mainly contains twin axle, orthoscopic, swing and online finishing formula.The processing method of online finishing is the relative motion of dependence of finishing ring and basal disc, produces the frictional force rotation, thereby drives workpiece motion s, is a kind of mechanism of non-active drive.
It is generally acknowledged as workpiece rotational frequency ω wWith lap speed ω pEquate, i.e. ω wpThe time, it is best that the surface to be machined material is removed uniformity.Reason is that according to Preston equation RR=kPV, the material removing rate RR of any is directly proportional with processing load p and relative velocity V on the workpiece surface to be machined.Work as ω wpThe time, the relative velocity equal and opposite in direction of workpiece and abrasive disk under the condition that each point processing load is identical on the workpiece, can think that the material removal is evenly.In the actual processing, the linear velocity of abrasive disk outside is big, and the linear velocity of inner edge is little.So it is also big more with the speed of finishing ring that the outside frictionally drives basal disc.The inner edge that finishing ring and basal disc are in abrasive disk and outside are different and carry out rotation by the speed of frictional force generation.
If finding only to lean on frictional force between finishing ring and the abrasive disk to drive the finishing ring according to practical work experience rotates and two kinds of situation can occur: 1) be not that each finishing encircles and can both rotate; 2) the finishing ring all rotates, but the velocity of rotation size is inequality.Under many circumstances, can only rely on levelling finishing ring position or abrasive disk surface to make its rotation, not only lose time, energy, the more important thing is that processing is unstable, can cause that workpiece quality is poor, working (machining) efficiency is low.
Summary of the invention
In order to overcome the deficiency that non-active drive, grinding precision are lower, cost is high that the conventional online finishing drives lapping device; The present invention provides the active drive lapping device that a kind of active drive, grinding precision are high, cost is low, make the finishing ring synchronously, active movement.
The technical scheme that the present invention adopts is:
A kind of active drive lapping device comprises finishing ring, basal disc and abrasive disk, it is characterized in that: also comprise drive motors, output gear, 3 equipment gears that receive powershift gear and can freely rotate; Said drive motors is installed on the support, and said output gear is connected on the drive motors and with the said powershift gear that receives and is meshed; The said powershift gear that receives is connected on the said finishing ring through bolt, and said finishing ring is fixed on the said abrasive disk through finishing ring fixture and can rotates around the fixed center line; Said basal disc is stuck in the said finishing ring; Be provided with screwed hole in the middle of the said abrasive disk; Said equipment gear is positioned at 3 to be received the center of powershift gear and all is meshed with the said powershift gear that receives, and said equipment gear below is fixed on the said abrasive disk through said screwed hole.
Further, said equipment gear is fixed on the axle, and said axle links together through bearing with fixed axis, and said equipment gear is fixed on the said abrasive disk via said screwed hole through fixed axis, and said equipment gear freely rotates around said fixed axis.
Further, the outside that is centered close to said abrasive disk of said output gear makes things convenient for the installation and removal of drive motors.
Further, said output gear, be parallel to each other by the axial line of powershift gear and equipment gear.
When the present invention used, the outside that is centered close to abrasive disk of output gear made things convenient for the installation of drive motors; When output gear rotates; Under the cooperation of equipment gear, 3 powershift gears that receive that are fixed on the finishing ring can move with identical speed, and the direction of motion is identical with the former direction of motion.Basal disc is stuck in the finishing ring; Because the finishing ring has identical speed; The workpiece that is fixed on so under the basal disc (basal disc links to each other with the finishing ring, and speed is identical) is identical with the relative velocity of abrasive disk, thereby has guaranteed identical materials removal amount; The uniformity of workpiece processing has improved the efficient and the quality of processing.
Among the present invention, said powershift gear and the finishing ring of receiving is completely fixed through bolt, guaranteed to receive powershift gear and repaired ring with speed, connects safe and reliable with bolt.Equipment gear is fixed on the axle, and axle links together through bearing with fixed axis, has guaranteed that equipment gear can freely rotate around fixed axis.According to working experience, in the middle of the abrasive disk individual screwed hole is arranged, fixed axis is fixed on the abrasive disk easily.
Beneficial effect of the present invention is embodied in:
1, it is controlled to make workpiece obtain good surface roughness and flatness, process time;
2, the stable online finishing abrasive disk of finishing ring has improved the abrasive disk quality;
3, thereby output gear can be adjusted rotating speed as required and makes surface of the work obtain better quality;
4, the machinery equipment cost is low, and processing conditions is simple, can obtain higher processing precision and working (machining) efficiency, is with a wide range of applications;
5, compare with other milling apparatus, can not produce very big noise during this lapping device.
