The 3rd lapping device 50 has two separately and a

parallel roller

51,52 and an abrasive band 53.This roller 51 is to be sheathed on drive link 22 second ends 222.This abrasive band 53 is and

second wheel

51,52 cover connection.

Consult Fig. 3, this lowering or hoisting gear 60 has an axle bed 61, single-revolution seat 62, leans a trace 63 and a driving lever 64 on vertical shaft 21 thrust bearings 213.This axle bed 61 has an axis hole 611 that radially runs through and wear for vertical shaft 21 second ends 212 pivot.This revolving bed 62 have rotating shaft 622, that a pedestal 621, runs through pedestal 621 be fixed on rotating shaft 622 1 ends and with the worm gear 623 of worm screw 29 engagements, an and rotating disk 624 that is fixed on rotating shaft 622 other ends, make rotating shaft 622 and motor 23 gyroaxises 231 form interlocks, it is one outstanding and be positioned at the backstay 6241 of eccentric position that this rotating disk 624 has.This trace 63 has one and bridges and the end 631, that is positioned at rotating disk 624 backstays 6241 is positioned on the machine wall 12 and the pivotable other end 632, and one is formed on the position of relative axle bed 61 axis holes 611 and the perforation 633 that links with vertical shaft 21.This driving lever 64 has a sliding piece 641 and one handle 642, this sliding piece 641 be with trace 63 against, but have the pushing end 6411 of a lifting trace 63.

Consult Fig. 1, Fig. 2, Fig. 4, Fig. 5, during action, the gyroaxis 231 of this motor 23 can see through the transmission of

belt pulley

26,27 and belt 28, drives drive link 22 and rotates, and makes drive link 22 see through the meshing relation of

helical gear

24,25, drives vertical shaft 21 synchronously and rotates.Whereby, the cylindrical shape abrasive band 31 of this first, second,

third lapping device

30,40,50, disc abrasive wheel 41 and abrasive band 53 just can be respectively by drive link 22 and vertical shaft 21 driven rotary, and the user can select different grinding forms according to the demand of processing.

Consult Fig. 2, and Fig. 3, Fig. 6, when gyroaxis 231 rotates, can reach and slow down and 622 rotations of drive rotating shaft synchronously through the meshing relation of the worm screw on the gyroaxis 231 29 with revolving bed 62 worm gears 623, make rotating shaft 622 drive rotating disks 624.Whereby, during these rotating disk 624 revolutions, can drive trace 63 1 ends 631 up and down with backstay 6241, making trace 63 1 ends 631 is the center with the other end 632, turn round along on the radial line Z direction with rotating disk 624, lower swing, and lifting thrust bearing 213 and drive vertical shaft 21 along moving on the radial line Z direction, and when trace 63 unclasps vertical shaft 21, utilize vertical shaft 21 gravity own to land downwards, and by helical gear 24, the 25 groove rotation directions that cooperatively interact, reach the characteristic that helical gear 25 still rotates with drive link 22, drive helical gears 24 with helical gear 25, keep the action of vertical shaft 21, be pressed in for 213 times on the trace 63 to thrust bearing to bottom offset, till this vertical shaft 21 can be driven by trace 63 again, the cylindrical shape abrasive belt wheel 31 that makes first lapping device 30 also can be with on the vertical shaft 21 except can rotating, following action, and the uniform grinding workpiece of energy, and make degree average of cylindrical shape abrasive belt wheel 31 abrasion, so as to increasing the service life.

Consult Fig. 4, Fig. 7, the user also can directly pull the handle 642 of driving lever 64 when gyroaxis 22 rotates, and the pushing end 6411 that drives sliding piece 641 is along the make progress lifting and locate an end 631 of trace 63 of radial line Z direction.At this moment, this trace 63 can upwards drive vertical shaft 21, make groove that vertical shaft 21 carries over

helical gear

24,25 mutual interlocks along the upwards lifting smoothly of radial line Z direction, the helical gear 24 to the vertical shaft 21 break away from drive link 22 on till the scope of helical gear 24 engagements.Whereby, just can in the process of drive link 22 turns, not drive vertical shaft 21 rotations, reach the purpose of stopping using first lapping device 30.

Conclude above-mentionedly, multi-functional carpenter's grinder of the present utility model is real to have had following listed advantage and effect:

The utility model can according to the user can be different process requirements, only use a transmission device 20 and easy structure, just can have three kinds of different grinding forms concurrently, and can select the surface of cylindrical shape abrasive belt wheel 31 or the disc abrasive wheel 41 or abrasive band 53 grinding workpieces of first, second,

third lapping device

30,40,50, make the utility model integrate multiple function of use, not only can reduce equipment cost, and volume is small and exquisite, and can effectively promotes economic benefit.
