Abstract
The utility model provides a kind of cutter mounting structure, solves leather processing industry, using to cutter changing inconvenience problem, including tool fitting and cutter, the tool fitting end face has an interface one, the knife end face has the interface two with one corresponding matching of the interface, the tool fitting and cutter are penetratingly equipped with a screw hole, the axis direction of the screw hole is equipped with a bolt on the screw hole and connects the tool fitting and cutter perpendicular to the axis direction of the cutter.The utility model install convenient, two stair-stepping interfaces one are easy to align with interface two；Positioning is accurate, after the alignment of two interfaces, then is directed at screw hole, plugs bolt, can be positioned；It is not easy to loosen, to the of less demanding of installation, because be stair-stepping Interference fit, in use, stair-stepping interface support torsion, therefore when installation bolt, screwing force need not be too big, is not easy to loosen during use.
Description
Technical field
The utility model is related to leather processing technique fields, refer in particular to a kind of cutter mounting structure.
Background technology
In leather processing field, need to use various cutters, in order to suitable for different processing requests, it is often necessary to replace
Cutter suppresses the side of cutter using screw during installing cutter, thus fixed, this fixed form,
It is required that screw tightening power wants bigger, in installation or replacement, larger screwing force, installation is required for replace laborious, it has not been convenient to.
Utility model content
In view of the above problems, the utility model provides a kind of cutter mounting structure, positioning is accurate, after the alignment of two interfaces, then
It is directed at screw hole, bolt is plugged, can be positioned；It is not easy to loosen, to the of less demanding of installation, because being that stair-stepping interface is matched
It closes, in use, stair-stepping interface support torsion, therefore when installation bolt, screwing force need not be too big, during use
It is not easy to loosen.
To achieve the goals above, the technical solution adopted in the utility model is as follows：
A kind of cutter mounting structure, including tool fitting and cutter, it is characterised in that：The tool fitting end face tool
There are an interface one, the knife end face that there is the interface two with one corresponding matching of the interface, the tool fitting and cutter
Penetratingly it is equipped with a screw hole, the axis direction of the screw hole is pacified perpendicular to the axis direction of the cutter on the screw hole
The tool fitting and cutter are connected equipped with a bolt.
Preferably, the interface one and the interface two are ladder-like.
Preferably, the central axis of cutter described in the screw hole axis runout, the distance deviateed are 1/5~1/4
The diametral distance of the cutter.
Preferably, there is counterbore, the shape of the counterbore to prevent spiral shell with bolt end cooperation for described screw hole one end
Bolt rotates, and the bolt end is concealed in the counterbore.
The utility model advantageous effect：
The utility model install convenient, two stair-stepping interfaces one are easy to align with interface two；Positioning is accurate, two interfaces pair
After standard, then it is directed at screw hole, plugs bolt, can be positioned；It is not easy to loosen, to the of less demanding of installation, because being ladder-like
Interference fit, in use, stair-stepping interface support torsion, therefore when installation bolt, screwing force need not be too big, makes
With being not easy to loosen in the process.
Description of the drawings
Fig. 1 is the stereogram of the utility model；
Fig. 2 is the front view of the utility model；
1- tool fittings, 2- cutters, 11- interfaces one, 21- interfaces two, 3- screw holes, 4- bolts.
Specific implementation mode
The technical solution of the utility model is illustrated with embodiment below in conjunction with the accompanying drawings.
As depicted in figs. 1 and 2, a kind of cutter mounting structure described in the utility model, including tool fitting 1 and cutter 2,
1 end face of the tool fitting has an interface 1, and the cutter 2 end face has to be connect with one 11 corresponding matching of the interface
Mouth 2 21, the tool fitting 1 and cutter 2 are penetratingly equipped with a screw hole 3, and the axis direction of the screw hole 3 is perpendicular to institute
The axis direction of cutter 2 is stated, a bolt 4 is installed on the screw hole 3 and connects the tool fitting 1 and cutter 2.
Specifically, the interface 1 with the interface 2 21 is ladder-like so that it is convenient to install, meanwhile, this knot
Structure installation is firm, and stair-stepping interface can preferably support torsion.
Specifically, the central axis of cutter 2 described in 3 axis runout of the screw hole, the distance deviateed is 1/5~1/4
The diametral distance of the cutter 2 facilitate installation in this way, required bolt does not need too long.
Specifically, there is 3 one end of the screw hole counterbore 31, the shape of the counterbore 31 to coordinate with 4 end of the bolt
Prevent bolt 4 from rotating, 4 end of the bolt is concealed in the counterbore 31, after counterbore 31 is filled in the end of bolt 4, so that it may
In other end tightening nuts, to tighten conveniently.
The utility model install convenient, two stair-stepping interfaces 1 are easy to align with interface 2 21；In installation process,
Positioning is accurate, after interface 1 is aligned with interface 2 21, then is directed at screw hole 3, plugs bolt 4, can be positioned；Bolt 4 is not easy
It loosens, to the of less demanding of installation, because being to be coordinated using stair-stepping interface 1 and interface 2 21, in use, ladder
The interface support of shape torsion, therefore when installation bolt 4, screwing force need not be too big, is not easy to loosen during use, in this way
With regard to easy to install and replace.
The embodiments of the present invention are described above in association with attached drawing, but the utility model be not limited to it is above-mentioned
Specific implementation mode, the above mentioned embodiment is only schematical, rather than restrictive, the common skill of this field
Art personnel are not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the scope of protection of the utility model.
