Abstract
The invention discloses a grinder which comprises a motor and a grinding disc driven by the motor. The grinder is characterized by being vertically arranged, a passive sleeve is arranged above the grinding disc, a workpiece is sleeved on a flat clamp and then loaded in the passive sleeve, the workpiece rotates through the passive sleeve during the grinding, and a free grinding material is poured on the grinding disc. The invention has the advantages of realizing the grinding through the grinding disc and the free grinding material, ensuring the processing precision and the surface roughness of the processing workpiece, and being capable of reaching higher level, and is especially suitable for finish machining of the plane of the small workpiece with high precision.
Description
Technical field
The present invention relates to the machining equipment field, is a kind of fine finishining milling apparatus specifically, particularly is directed against the miniature workpiece grinding use that the flatness and the depth of parallelism are had relatively high expectations.
Background technology
Past; The miniature workpiece that the depth of parallelism and flatness is had requirement; General what adopt is that surface grinding machine is accomplished, and the machining accuracy of surface grinding machine is limited, and the workpiece and the thin-wall part of having relatively high expectations for flatness and the depth of parallelism then do not reach required precision sometimes; Maybe can reach machining accuracy but working (machining) efficiency is very low, particularly bigger for the workpiece difficulty of processing of machining accuracy below 0.005mm.
Summary of the invention
For solving problem, the purpose of this invention is to provide a kind of grinder that uses free abrasive for the bad processing of high-precision workpiece planarization.For example: the round piece processing back plane degree that this equipment pair and diameter are not more than 80mm can reach and be no more than 0.002mm, and the depth of parallelism can reach below the 0.004mm..
The technical scheme that the present invention addresses the above problem is:
Changing grinder is vertical installation; And drag abrasive disk rotation through motor, after being sleeved on the plate jig, workpiece reinstalls, through being realized the rotation of workpiece in process of lapping by moving sleeve by moving sleeve; Spill free abrasive at the abrasive disk top-pour; Workpiece top guaranteeing workpiece in the location of vertical direction, and leans on the weight of balance weight body to exert pressure for three workpiece of below with discoid balance weight body compacting, and guaranteeing has enough uniform grinding forces in the process of lapping;
The said peripheral locating wheel of being taken turns and being fixed on the frame by the interfix that is arranged on the abrasive disk by moving sleeve is fixed, and said locating wheel is in free rotation state;
Concrete annexation is: motor 03 is connected with base 01 with bolt through electric machine support 02 with driving pulley 04; Abrasive disk 13 is connected with main shaft 09 through ring flange 12; Main shaft 09 forms rotating mechanism through the bearing 08 and second sleeve 10, and second sleeve 10 is connected with base 01 with the support 06 that channel-section steel is processed through the circular connecting plate of lower end.Oil drain pan 11 is fixed together through the jackscrew and second sleeve 10; Interfix wheel 14 is connected with abrasive disk 13 with bearing through bolt; Interfix wheel 14 is in free rotation state with peripheral locating wheel 14; Peripheral locating wheel 14 also links to each other with simple rack with bearing through bolt, and simple rack is connected fixing through bolt with the oil drain pan upper end.
The invention has the beneficial effects as follows through abrasive disk and free abrasive and realize attrition process, guaranteed that the machining accuracy of processing work and surface roughness can reach than higher level, the fine finishining on particularly suitable and high-precision miniature workpiece plane.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is an abrasive disk place partial top view.
The specific embodiment
Like Fig. 1, shown in Figure 2; Motor 03 is connected with base 01 with bolt through electric machine support 02 with driving pulley 04; Abrasive disk 13 is connected with main shaft 09 through ring flange 12; Main shaft 09 forms rotating mechanism through the bearing 08 and second sleeve 10, and second sleeve 10 is connected with base 01 with the support 06 that channel-section steel is processed through the circular connecting plate of lower end.Oil drain pan 11 is fixed together through the jackscrew and second sleeve 10; Interfix wheel 14 is connected with abrasive disk 13 with bearing through bolt; The rotating shaft of interfix wheel 14 and the rotating shaft of main shaft 09 are same straight line; Two locating wheels (interfix wheel and peripheral locating wheel) 14 all are in free rotation state, and peripheral locating wheel 14 also links to each other with simple rack with bearing through bolt, and support is connected fixing through bolt with the oil drain pan upper end.
Transmission principle of the present invention: motive power is provided by motor 03; Drive pulley 04 through front end connects belt 05; Belt 05 is connected to negative pulley wheel 07 in the bottom, negative pulley wheel 07 links to each other with main shaft 09, and the rotating tee of main shaft 09 is crossed ring flange 12 and is passed to abrasive disk 13.During abrasive disk 13 rotation, be positioned on the abrasive disk 13 by moving sleeve 15 through two locating wheel 14 fixed positions under abrasive disk 13 drives, carry out rotation owing to can be made by moving sleeve at the interior out conductor speed difference on abrasive disk 13 diametric(al)s by moving sleeve 15.Also can be done similarly to rotatablely move by the circular clamp 16 in the moving sleeve 15 together with workpiece, be positioned over workpiece three holes of circular clamp in then forms grindings with abrasive disk 13 relative motion.
