Description

The desk-top wood working drilling and milling machine of rocking arm

The utility model belongs to the operation technique field, specifically a kind ofly is used for the lathe that carpenter mills processing.

Along with the manufacturing development of furniture, particularly modern New-type plate furniture, because the variation of its style, that does manual work is fastidious, the decoration office, the hotel, environment such as family room, be subjected to liking of people day by day, the making of new-type board-like furniture is made different with traditional furniture, the requirement of making precision is further improved, zero, there is dedicated connections spare to connect mutually between parts, and be used for the various holes of connection effect, the processing of groove is crucial manufacturing procedure, present existing device is as bench wood lathe (ZL92228021.5), carpenter's perforator (ZL92204491.0), multi-functional carpenter's perforator (ZL93207677.7) etc., be used for the boring of narrow batten mostly, groove milling, range of application is narrow; Hand mills machine with electric drill, is difficult to guarantee positional precision during operation; Porous row formula perforating lathe costs an arm and a leg, and is applicable to big in batches efficient perforating occasion, and is improper to the production of small lot, single products.

The purpose of this utility model is to provide a kind of flexible operation, applied range, the desk-top wood working drilling and milling machine of the rocking arm that machining accuracy is high.

The utility model comprises workbench, rocking arm and main spindle box.Workbench one side of the band groove of falling the T-shape vertically is equipped with columniform column, rocking arm vertical with column of suit on the column.Rocking arm rotates with lowering or hoisting gear and is installed on the top of column through bearing, and elevating screw matches with nut on the rocking arm, and main spindle box is installed on the rocking arm through guide rail.

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 is an overall structure schematic diagram of the present utility model.

Fig. 2 is that rocking arm of the present utility model rotates and the lifting device structure schematic diagram.

Fig. 3 is rocking arm of the present utility model location, locking mechanism schematic diagram.

Fig. 4 is a main spindle box structural representation of the present utility model.

Fig. 5 is the partial cutaway diagrammatic sketch of main spindle box of the present utility model along the rocking arm cross section.

The conical surface and the taper hole on the workbench 6 of Fig. 1 central post 1 bottom match merga pass adapter sleeve 5 by bolted, to guarantee the perpendicularity requirement of column and workbench.On the table top of workbench 6 groove of falling the T-shape is arranged, be used for sectional fixture and sliding table annex etc.The rocking arm 3 that can rotate around it is housed on the column 1, rotates handwheel 14 and can drive the rocking arm lifting through leading screw 12 and nut 11, rotation handwheel 2 can make rocking arm unclamp or be clamped on the column, and scale 4 is used for the accurate location of rocking arm.Main spindle box 7 is installed on the rocking arm 3, through wheel and rack 8 main spindle box 7 is moved radially along " chevron " guide rail on the rocking arm, and 9 pairs of main spindle boxes of block have moved position-limiting action, is fixed on the accurate location that scale 10 on the rocking arm is used for main spindle box.The rotation of rocking arm and lowering or hoisting gear 12 are installed on the column top, bear the rotation and the lifting task of rocking arm.

Among Fig. 2 at the tumbler position of rocking arm, housing 13 inside, two

thrust ball bearings

20 and 21 are equipped with in column 1 upper end, play the axially mounting effect, bear axial force up and down respectively, and this power finally is delivered on the column 1; Radial ball bearing 18 plays radial support effect and bearing radial force.Locking nut 16 and check washer 17 are used for regulating the gap of bearing.Lifting position at rocking arm, the bearing 25 of pushing the ball plays the axially mounting effect, bear axial gravity, and this power power unloaded on housing 13, journal bearing 27 plays radial support effect and bearing radial force, and locking nut 28 and check washer 29 are used for regulating the gap of bearing, rotates the handwheel 14 with leading screw 12 ends connection, make the rocking arm lifting through the leading screw pair of nut,

end cap

15,22,30 usefulness bolted are on housing 13.

Fig. 3 transfer is started to take turns 2 and rocking arm 3 barrels can be clamped and loosen on column 1, two Elastip pins 31 radially are installed on this barrel, when rocking arm 3 along or rotate counterclockwise＜90 ° the time, pin 31 can eject and embed column 1 outside vertically in the straight trough of symmetry, plays position-limiting action.Lifting nut 4 usefulness bolted are on rocking arm 3.

Main shaft 53 is supported in the rack sleeve 47 by thrust ball bearing 46,49 and radial ball bearing 44,51 respectively among Fig. 4, Fig. 5, and regulates bearing clearance and locking by cover 43, nut 41, pad 42.Main shaft 53 upper ends are the external splines shape, and match with inner spline housing 35.Inner spline housing 35 upper ends are supported in the end cap 33 by ball bearing 34, and the lower end is supported in the cover 40 by ball bearing 39.Tower or belt pulley 37 are fixed on the inner spline housing 35, and motor 70 is fixed on the casing by bolt, and the motion of motor is driven main shaft 53 and rotated by its output diameter of axle belt wheel 71,37, interior external splines.Have tooth bar and gathering sill on rack sleeve 47 external cylindrical surfaces, limit its rotation and axial displacement by pin 48.Axle 60 two ends are supported in the box body hole by ball bearing, the bearing two ends respectively have a circlip to limit its axial displacement, handwheel 59 is fixed on the axle 60 with dial 62 via pins, wind spring 61 two ends embed respectively in casing and the axle 60, rotate handwheel 59 and by the tooth bar engagement on the gear 63 that connects firmly on it and the rack sleeve 47, can drive spindle assemblies moves as vertical, dial 59 can be indicated its displacement, but the gravity of the spring force balancing main shaft assembly of wind spring 61, spindle assemblies is bounced back easily, and 35 pairs of spindle assemblies of fixed cover 52 and inner spline housing play the guiding role.Axle 57 two ends are supported in the box body hole by ball bearing, the bearing two ends respectively have a circlip to limit its axial displacement, handwheel 56 is fixed on axle 57 ends, the gear 66 that rotation handwheel 56 connects firmly on axle 57 other ends rolls on tooth bar 8, move along rocking arm 3 thereby drive whole main spindle box 7, measure its precise displacement by scale 10.Axle 55 1 ends and box body hole matched in clearance, the other end and box body hole spiral marking connection, and have bulb to cut with scissors knot mutually with briquetting 67, turning handle 54 can make briquetting press to sliding surface on the rocking arm 3, and main spindle box is lock onto on the rocking arm.Whole main spindle box 7 is installed on the rocking arm 3, by the San shape guide rail face guiding of deciding, pays spigot surface by marking closely the size that screw 69 and spline 68 are regulated gaps.

The utility model is applicable to the drilling of various connection pin-and-holes in the furniture manufacturing, and various types connects the milling of tongue-and-groove, flexible operation, convenient, the machining accuracy height, a tractor serves several purposes, especially be easy to the location processing of the connection pin-and-hole on the large-sized sheet material face, if the travelling table annex is installed on the workbench, but the upholstery border of milling various types again, therefore, the utility model is particularly suitable for the processing and fabricating of many kinds, the modern board-like furniture of small lot.
