Description

The surfacer cutter holder

The utility model relates to a kind of surfacer cutter holder, particularly relates to a kind of barb portion card by cutter and ends at locating slot, to obtain the surfacer cutter holder of good location and difficult drop-off.

As shown in Figure 1, 2, the cutter arrangement of existing surfacer is made up of a knife bar body 1 cylindraceous, some cutters 2 and some lock-connecting pieces 3.

Knife bar body 1 is provided with some caulking grooves 102 in its outer peripheral face 101 equal intervals, and a side of each caulking groove 102 is in abutting connection with a dregs guiding groove 103 is arranged.

Cutter 2 has a blade 201 and that protrudes knife bar body 1 outer peripheral face 101 can embed the knife back 202 of knife bar body 1 caulking groove 102.

Lock-connecting piece 3 has a threaded shank 301 and that can be bolted in knife bar body 1 caulking groove 102 bottoms can compress cutter 2 and heavy hideing in the head 302 at caulking groove 102 tops.

Above-mentioned surfacer cutter assembly program is as follows: earlier this cutter 2 is inserted in the caulking groove 102 of knife bar body 1, the threaded shank 301 with lock-connecting piece 3 is screwed into caulking groove 102 again, thereby and utilizes head 302 side pressure cutters 2 to reach the purpose of aligned cutting tool 2.

Though above-mentioned surfacer cutter holder can be located cutter 2,, the consolidation method of this compression type still has some deficits.When the planing wood operation is carried out in the surfacer entry into service, the cutter of straight insertion caulking groove might skid off, so just can't obtain smooth planing wood effect, adding cutter 2 is straight being fixed on the knife bar body 1, therefore, when carrying out the planing wood action, the whole blade of cutter is to contact with thing to be processed with the line way of contact, make that the drive motor load is excessive because cutting force is concentrated, thereby cause the waste of electric power.

The purpose of this utility model is to provide a kind of barb portion card by cutter to end at locating slot, thereby obtains the surfacer cutter holder of good location and difficult drop-off.

The utility model surfacer cutter holder is made up of knife bar body, cutter and protecting cover.The outer peripheral face of cylindric cutter body equidistantly forms some helical form locating slots, and an interior of locating slot has a caulking groove, and caulking groove has a shoulder.Another sidewall of locating slot extends a retaining edge from knife bar body outer peripheral face towards the locating slot direction, makes this interior form a depression.Cutter has the blade of a protrusion knife bar body outer peripheral face, one implants the knife back of knife bar body caulking groove, equidistantly be provided with plurality of opening at knife back place, the end section of perforate is bent to form a barb portion outwardly, perforate design by equidistant setting, make the cutter can be, and its barb portion card end the shoulder at caulking groove along the angle flexural buckling of the helical form locating slot of knife bar body.Protecting cover has the curvature identical with the helical form locating slot of knife bar body, protecting cover has some equidistantly axial interlocking holes of running through its bottom surface from its end face, lid has one to be used for the inclined side of contact cutter lateral surface and another is affixed on the side of locating slot depression, the be positioned retaining edge institute block of groove of protecting cover end face.When lock-connecting piece was screwed into the interlocking hole, the protecting cover squeezing knife tool also borrowed the card of cutter barb portion only to act on and cutter can be fixed firmly.
