Fine tuning, can easily be adjusted to adapt to the processing of different materials.
Cutter head is a significant components of disposable type circular knife, and cutter head is due to being quick-wear part, it is often necessary to maintenance replacement.
Currently, be all to need individually to be fastened by bolts on cutter hub when the bit replacing of disposable type circular knife is installed on the market,
Since cutter head quantity is various, installation and replacement are very troublesome, time-consuming and laborious.Due to the presence of problem above, it is necessary to give for we
It improves.
Summary of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of disposable type woodwork spiral knife, and structure is simple, easy for installation,
Greatly improve assembly efficiency.
The technical solution adopted by the present invention to solve the technical problems is: a kind of disposable type woodwork spiral knife, including cutter hub,
Cutter head and shaft, the cutter hub are equipped with the screw type cutting item of evagination, and the cutter head is mounted on the cutting item, the knife
The shaft is installed in vivo, limiting slot is provided in the shaft, limited block is provided on the limiting slot, the cutter head passes through
Fixing axle is passed through cutter hub and is fixed in the shaft, and the head setting of the fixing axle is fluted, and the groove is stuck in institute
It states on limited block.In this way, cutter head to be mounted successively can be first mounted on the cutter hub in advance by the fixing axle, so
The limited block in the limiting slot in the shaft is matched with the groove in the fixing axle afterwards, is directly inserted into the shaft
Into the cutter hub, the disposable installment work of all cutter heads is realized, it is simple and quick without single installation.
In above-mentioned technical proposal, it is preferred that the limiting slot includes the first limiting slot and the second limiting slot, first limit
Position slot is communicated with second limiting slot, and the angle of the end face of first limiting slot and the shaft is 85 ° to 88 °, described
The angle of the end face of second limiting slot and the shaft is 78 ° to 82 °.In this way, the fixing axle can be made to be mounted on institute
The active force that the limited block in second limiting slot is received when stating on the second limiting slot, by the fixing axle together with the knife
Head is tightly secured on cutter hub.
In above-mentioned technical proposal, it is preferred that the limiting slot annular is uniformly distributed, and quantity is 4-6 item.In this way, can fit
For different blade type.
In above-mentioned technical proposal, it is preferred that the cutting item has 4 layers.
In above-mentioned technical proposal, it is preferred that the both ends of the shaft is equipped with fastener, and the fastener fastens the shaft
On the cutter hub.In this way, fixing axle can be made to be clamped securely in the shaft, it is safe and reliable.
In preceding solution, it is preferred that the fastener is to be threadedly coupled with the shaft.In this way, conveniently tearing open
It unloads, and the power of fastening can be made bigger.
In preceding solution, it is preferred that the fastener is nut.
The beneficial effects of the present invention are: being provided with limiting slot in the shaft, limited block, institute are provided on the limiting slot
It states cutter head cutter hub is passed through by fixing axle and be fixed in the shaft, the head setting of the fixing axle is fluted, described
Groove is stuck on the limited block.Cutter head to be mounted successively can be first mounted on the cutter hub in advance by the fixing axle,
Then the limited block in the limiting slot in the shaft is matched with the groove in the fixing axle, directly inserts the shaft
Enter into the cutter hub, realize the disposable installment work of all cutter heads, without single installation, structure is simple, installation side
Just, assembly efficiency is greatly improved.
