The specific embodiment

Below by most preferred embodiment and accompanying drawing the utility model spiral planing tool device is elaborated.

Shown in Fig. 2,3,4,5, the utility model spiral planing tool device is applicable to and is installed on a surfacer (figure do not show), and this preferred embodiment comprises a power transmission shaft 20, a key piece 30, most cutterheads 40, most sheet blade 50, most support bolt 60 and two keepers 70.

This power transmission shaft 20 comprises first keyway 22 that is arranged at this section of being nested with 21 around 21, one of the sections of being nested with of an axis I along this axis I, reaches respectively two thread segments 23 along the extension of this axis I undergauge from two opposing ends of this section of being nested with 21.

This key piece 30 is fixed in this first keyway 22 and local this section of being nested with 21 of protruding.

Each cutterhead 40 comprises respectively with not isometrical degree inner ring surface 41 and outer ring surface 42 around this axis I, be provided with and be majority second keyway 43 that equal angles distributes from this inner ring surface 41 towards this outer ring surface 42, a groove 44 that is provided with towards this inner ring surface 41 from this outer ring surface 42, lay respectively at a ring piece 45 and a lock dog 46 of these groove 44 both sides, and a screw 47 that is arranged at this lock dog 46.

This ring piece 45 has one and connects the abutment face 451 that this outer ring surface 42 and this groove 44 and contiguous these lock dog 46 usefulness recline for this blade 50.

This lock dog 46 has one and radially is provided with outward from this groove 44 and uses the supporting face of putting for this blade 50 461.

This screw 47 is that the direction of vertical this supporting face 461 in edge is arranged at this lock dog 46.

Preferably, this cutterhead 40 also comprises most short slots 48 that are provided with and stagger with described second keyway 43 towards this inner ring surface 41 from this outer ring surface 42, has the effect that can alleviate these cutterhead 40 weight, in addition, this cutterhead 40 in the utility model be material with powder metallurgy, make with mould molding or with wire cutting method.

In this preferred embodiment, each sheet blade 50 has a face that posts 51 on the supporting face 461 that is seated in this lock dog 46 respectively, one is in reverse to this and posts less external 52 of face 51 and area, connect this and post face 51 and several planing inclined-planes 53 that should external 52, and this external 52 of connection posts the perforation 54 of face 51 with this.

During assembling, only need the face that posts 51 of this blade 50 is seated on this supporting face 461, and one of them the planing inclined-plane 53 that makes this blade 50 is against abutment face 451 of this ring piece 45, again this bolt 60 is passed this perforation 464 and lock this screw 47, just these blade 50 locks can be put and be fixed in this lock dog 46, another planing inclined-plane 53 of this blade 50 protrudes this supporting face 461 simultaneously, can see through this planing inclined-plane 53 planing timber.

What deserves to be explained is, as shown in Figure 5, when the area of the face that posts 51 of this blade 50 greater than this area of external 52, then the abutment face 451 of this cutterhead 40 and the angle between this supporting face 461 are less than 90 degree, so can increase the rest surface between this planing inclined-plane 53 and this abutment face 451, can improve the firm effect of this blade 50 relatively.In addition, the angle between this external 52 and this planing inclined-plane 53 is best greater than 135 degree.

Shown in Fig. 7,8, when the area of the face that posts 51 of this blade 50 less than this area of external 52, then the abutment face 451 of this cutterhead 40 and the angle between this supporting face 461 are not less than 90 degree, so can increase the rest surface between this planing inclined-plane 53 and this abutment face 451, can improve the firm effect of this blade 50 relatively.

Described keeper 70 is two nuts in this preferred embodiment, and screw lock has the effect that can make described cutterhead 40 location in two thread segments 23 of this power transmission shaft 20 respectively.

During assembling, as Fig. 2,3,4,5, shown in 6, at first this key piece 30 is inserted in first keyway 22 of this power transmission shaft 20, successively described cutterhead 40 is nested with outside this power transmission shaft 20 then, seeing through described second keyway 43 simultaneously is placed on this key piece 30 and the lock dog 46 of adjacent two cutterheads 40 is staggered along this axis I, so just can make described blade 50 along this axis I shape arrangement in the shape of a spiral, after most cutterheads 40 of predetermined quantity are installed by the time, again described keeper 70 is distinguished screw locks in two thread segments 23 of this power transmission shaft 30, just can make described cutterhead 40 fix and finish assembling of the present utility model.

In addition, shown in Fig. 5,6,7,8, this preferred embodiment also comprises second keyway 43 that is mounted on described cutterhead 40 and the balance weight 80 symmetrical with this key piece 30, has the effect of the rotary balance degree that can improve the utility model spiral planing tool device.

Conclude above-mentionedly, the utility model spiral planing tool device has effect as described below and advantage, so can reach the utility model purpose really:

Put the lock dog 46 that is fixed on described cutterhead 40 because blade 50 described in the utility model is locks because each cutterhead 40 all is the design of identical configuration, make the utlity model has make more convenient, save time and can reduce the effect and the advantage of manufacturing cost.
