Description

Planer head

The present invention relates to a kind of planer head that is used for planer.

In a kind of known planer head or knife rest of this area (DE4137623), cylinder-shaped body is fixed on one, its radial side flattens, in order to pressing plate and the clamping plate made by aluminium section bar that receive two planing tools and planing tool is compressed, form screw on the longitudinal edge that flattens, these screws separate each other in the axial direction.The hold-down bolt that screws in the screw passes each clamping plate on each planation surface of main body, their exterior contour is circular consistent with main body.One side of each clamping plate is positioned on the main body, and opposite side is positioned on the pressing plate, and the latter is pressed on the main body.And each pressing plate is fixed on a planing tool on the main body, and this planing tool roughly protrudes above the circular contour of main body diametrically.

The advantage of comparing with the main body of being made by aluminium section bar (this main body must be processed) comprehensively according to planer head of the present invention is, because favourable punching press and the overlapping method of employing price, so cost is lower.Main body can be with very little tolerance punching out, and stacked with big slightly a little tolerance, thereby obtains a kind of high reliability of technology.By making bigger cavity, can make the weight of main body very little in each stamping upper punch.

According to a preferred embodiment of the present invention, at least one screw thread carries part, and to pass stamping vertically folded, and this screw thread carries part and is preferably a rectangular strip, and its shape is inserted the overlapping punching press otch in the stamping identically.Preferably, the screw thread lath floats and supports, and in other words, remains between the emulsion sheet with certain end play, and the stamping in the screw scope respectively has a punching press breach, and this breach extends to the edge of adjacent stamping from the punching press otch.The axial width dimension that unsteady support by the screw thread lath and the stamping that is made of the adjacent stamping that has the punching press breach are folded selected can make the precision of pitch of holes not be subjected to the influence of the thick tolerance sum of sheet.What advantageously, be made of the folded section of this stamping folds the shank of bolt of the axial width respective threads breach of section greater than hold-down bolt with stamping.

Describe the present invention in detail below in conjunction with embodiment shown in the drawings.

Fig. 8 is a view that is attached to the screw thread lath in the main body,

Fig. 9 is the sectional view along the IX-IX line among Fig. 8.

Be pressed on the main body 11 by means of hold-down bolt 12 to have 11, two planing tools 13 of a main body with the planer head of the hand olaning machine shown in the profile among plan view, Fig. 2 in Fig. 1, they stretch out from the circular outline of main body 11 in the opposite direction.Main body 11 rotation is fixedly fastened on one 10, and this is contained in the housing (not shown) of hand olaning machine by gantry post, and by a motor through an actuator drives.

As can be seen, main body 11 is a solid cylinder from Fig. 2 and 3, and its two opposite sides flatten.Each planation surface 111 is used for tightening of two planing tools 13.For this reason, place a planing tool 13 on each planation surface 111, and be fixed on the main body 11 with a pressing plate 14.Having the tab 16 that a groove 15, forms on pressing plate 14 on the knife back that deviates from planation surface 111 of each planing tool 13 embeds in these grooves.Each pressing plate 14 is clamped on the main body 11 by clamping plate 17, clamping plate 17 one sides are supported on the back side that deviates from planing tool 13 of pressing plate 14, another side is supported on and flattens on the side 111, for this reason, three hold-down bolts 12 that are provided with one by one in the axial direction pass each clamping plate 13, screw in the threaded hole 18 that forms in main body 11.Each planing tool 13 is positioned at the front of clamping slot 19 of a recessed main body 11 on direction of rotation before.

The profile of the main body from Fig. 4 as can be seen, main body 11 is made of many adjacent stampings 21, these thin slices are assembled into a stamping folded 20.Stamping folded 20 or be welded is perhaps sealed by the plastic pressure injection moulding with axle 10 and is formed.Each screw 18 that is used to tighten a planing tool 13 is positioned at a screw thread and carries part 22, and screw thread carries the part shape and embeds stamping folded 20 identically.In described embodiment, it is a rectangular strip 23 (Fig. 4,8 and 9) that screw thread carries part 22, screw 18 these laths of incision, and they equidistantly distribute in the axial direction.In the two spiral laths each penetrates punching press space 24, and punching press space 24 penetrates stamping 21 (Fig. 6 and 7), aligns each other in stamping folded 20.The stamping 21 (under be called emulsion sheet 211) of deciding stamping folded 20 at the both sides lateral confinement does not have this punching press space (Fig. 5), and therefore, after emulsion sheet 211 assembled, the thread plate 23 that inserts punching press space 24 is fixing (Fig. 4) in the axial direction.Preferably, screw thread lath 23 floats and supports, and in other words, they have end play in a way.

Stamping 21 is stamped to form by simple steel plate, and have as Fig. 5,6 with three kinds of different forms shown in 7.Shown in Figure 6 is two emulsion sheets of having described 211, and it has medium pore 25 and two the arc stamping-out parts that constitute groove 19 that are used to pass axle 10 also as other stamping 21.The stamping that illustrates in pairs in Fig. 6 and 7 also has this stamping-out shape, also has two

cavitys

26,27 that are used for respectively receiving the punching press space 24 of a screw thread lath 23 and play the weight reduction effect simultaneously.(these thin slices are arranged in the scope of screw 18 of screw thread lath 23 in stamping 21 among Fig. 7, therefore hereinafter referred to as screw thread sheet 212), compare with the punching sheet shown in Fig. 6 and also to have a punching press breach 28, it stretches out from a side in each punching press space 24, extends to adjacent chip edge.The bolt column of hold-down bolt 12 can pass these punching press breach 28, thereby can screw in the screw 18 on the screw thread lath 23 that is inserted in the punching press space 24.

Can clearly be seen that from Fig. 3 and 4 three narrow axial lamination sections that are made of screw thread sheet 212 adjacent one another are are set, and the axial width of each lamination section is greater than the diameter (Fig. 4) of the screw in the screw thread lath 23 18 between stamping 21 as shown in Figure 6.

The present invention is not limited by the foregoing description.Therefore, screw thread carries part 22 and also can not be one and hold the folded screw thread lath of stamping in the axial direction.For example, can be with between the insertion stamping 21 spaced apart in the axial direction of the sheet of three precision stampings, cutting goes out a radially screw thread in each sheet.If want screw of cutting, can adopt the precision stamping sheet of 8mm radial width with a M6 helix.Such main body 11 looks and very elephant shown in Figure 3 that difference is a wide precision stamping sheet that has two screws at the bundle section place that former cause screw thread sheet 212 constitutes together now just, and cutting goes out a flat side on each precision stamping sheet.

Planer head also can only be adorned a planing tool.In this case, in the cross sectional shape of the stamping shown in Fig. 6 and 7, no longer include the second punching press otch 24, in stamping folded 20, no longer include the second screw thread lath 23.The profile that removes planing tool one side in the stamping 21 is for circular, and therefore, stamping 21 only flattens in a side.
