[specific embodiment]

As Fig. 2, shown in Figure 3, the preferred embodiment of the utility model cutterhead jig arm device 100, be to be removably to be installed in a cutterhead 200 peripheries, and a cutter 300 clampings can be located, this cutter 300 has a columnar portion 310, and is arranged on the awl post portion 320 of these columnar portion 310 1 sides along axis, and this columnar portion 310 has circular groove 330, two 180 degree and be located at the draw-in grooves 340 of these circular groove 330 1 sides along axis at interval that are arranged with on outer peripheral face.And this jig arm device 100 comprises a positioning seat 10, and is installed in spring clip 20, two on this positioning seat 10 and these spring clip 20 compactings can be positioned at locking unit 30, on this positioning seat 10 and be subjected to these cutter 300 stoppers to produce the shield 40 and that slides with respect to this positioning seat 10 to provide this shield 40 back of sliding to produce the flexible member 50 of replying action.

This positioning seat 10 have an extensible intersection in the center line L of these cutterhead 200 axis, a pair of should center line L wherein an end and be installed in anchor portion 11 on this cutterhead 200, a pair of should the center line L other end and be located at the bottom with the bearing end 12, of these anchor portion 11 opposite settings and be located at these chute 13 tops and be located at the caulking groove 16 that the block piece 15 and of these chute 13 belows is arranged on the top and takes the shape of the letter U along the groove 14, two that this center line L extends along the chute 13, that this center line L extends.This bearing end 12 have one along center line L and towards inside recessed shrinkage pool 121, be convexly equipped with on this shrinkage pool 121 inner ring surfaces and can for the nested socket part 122 of the circular groove 330 of this cutter 300 and with the screw locking above this socket part 122 and can stretch the clamp 123 that is located in this draw-in groove 340.

This spring clip 20 generally is the U type, just is embedded in the caulking groove 16 of this positioning seat 10, and has one and be installed on this positioning seat 10 and be engaged on these binding sheet 21 2 ends respectively and be divided into the cartridge clip sheet 22 of this center line L both sides perpendicular to the binding sheet 21 and two of this center line L.These cartridge clip sheets 22 respectively have one with the clipping end 221 of elasticity clipping on the columnar portion 310 of this cutter 300, and this clipping end 221 is wound into loop shaped.

These locking unit 30 respectively have a pad 31 and that is compressed on cartridge clip sheet 22 stage casings of this spring clip 20 and pass this pad 31 and be arranged in screw 32 on the positioning seat 10.

This shield 40 is to be plugged in slidably in the chute 13 of this positioning seat 10 along center line L, and has to be located at end face central authorities and can to stretch to pushing block 41 and two in this groove 14 and be located at the both sides, bottom surface and can be resisted against fastener 42 on these block pieces 15 in good time.

This flexible member 50 is to be installed between this positioning seat 10 and the pushing block 41, and just is set in this groove 14, and its elastic force can make this shield 40 cover in this shrinkage pool 121 bottoms.

As Fig. 4, shown in Figure 5, under normal condition (being exactly when not inserting cutter 300 as yet), this shield 40 is subjected to the elastic force effect of this flexible member 50, can cover below this shrinkage pool 121, and this shield 40 utilizes these fasteners 42 to ending on these block pieces 15, can produce the effect of location with respect to this positioning seat 10.

As Fig. 6, shown in Figure 7, when this cutter 300 is inserted in these shrinkage pool 121 inside, utilize cutter 300 to push away to pull this shield 40, can make this shield 40 by a hidden position of covering originally below this shrinkage pool 121, be moved to an enable possition towards these anchor portion 11 directions, at this moment, this fastener 42 is away from this block piece 15, and utilize the interlocking of sheathed, clamp 123 with the draw-in groove 340 of this circular groove 330 and socket part 122, and this cartridge clip sheet 22 is clipped on the columnar portion 310 with elastic bunch, just can make this cutter 300 obtain strong fixs.

Therefore, advantage of the present utility model is as follows:

One, 200 of this cutterheads are made discoid merely, and this jig arm device 100 is to make in a large number with modularity, after making, assembly are finished, be locked in this cutterhead 200 peripheries again, so the center line L of this jig arm device 100 can be exactly in alignment with cutterhead 200 central axis.And the manufacturing of this jig arm device 100, processability are not only more or less freely, and cost is also lower.

Two, if there is a jig arm device 100 to damage, only needs the jig arm device 100 that damages is pulled down on this cutterhead 200, and can replace new jig arm device 100 at once, thus can not influence the running of processing machine, in maintenance quite easily, save time, and do not influence production capacity.

Three, state as shown in Figure 4 at this jig arm device 100 as yet not during clipping cutter 300, utilizes 40 of this shields can prevent that in hidden position the iron filings spray from wearing this shrinkage pool 121 and falling to this positioning seat 10 tops, and can guarantee to keep accurately when this cutter 300 is inserted.

Conclude above-mentionedly, the utility model cutterhead jig arm device is to make in a large number with modularity, and is and removably is assembled on the cutterhead, not only makes, assembly is easy, and can promote the production capacity of processing machine, can reach the purpose of this utility model really.
