Description
Technical field
The utility model relates to machine tool technical field, is specifically related to the removable cutter of a kind of cutter head.
Background technology
For the machining of complex part, usually needing to change many different cutters can complete.Each tool changing all needs cutter to disassemble from lathe cutter saddle, then installs another cutter, and such tool changing mode wastes time and energy, and working (machining) efficiency is low.In addition, so many cutter, add quantity and the quantity in stock of cutter, be unfavorable for the management of cutter, the cost of manufacture of cutter is higher.
Summary of the invention
For the problems referred to above, the purpose of this utility model is to provide the removable cutter of a kind of cutter head.
Realize the technical solution of the utility model as follows:
The removable cutter of a kind of cutter head, comprise handle of a knife and cutter head, described cutter head is provided with the connecting portion be connected with the head end of handle of a knife, connecting portion is provided with the locking breach passed through for bolt, the head end of described handle of a knife is provided with the accommodating cavity of accommodating connecting portion, and the axis of accommodating cavity and the axis collinear of handle of a knife, the sidewall of head end offers the bolt hole running through accommodating cavity, the axis of bolt hole and the intersect vertical axis of accommodating cavity, described cutter head is fixedly connected with the head end of handle of a knife by bolt and nut.
Further, described accommodating cavity comprise head end and the handle of a knife coaxial line being arranged on handle of a knife axially extending bore, be arranged on the spherical hollow space be communicated with axially extending bore in head end, described bolt hole runs through spherical hollow space, and the centre of sphere of described spherical hollow space is positioned on the intersection point of the axis of bolt hole and the intersect vertical axis of axially extending bore; Described connecting portion comprises laterally zygomorphic two parts, the laterally zygomorphic two parts of connecting portion include the locking section being placed in centre of sphere cavity and the changeover portion being placed in axially extending bore, between two changeover portions, Formation cross-section is the breach of stepping down of isosceles triangle, forms the locking breach passed through for bolt between two locking sections.
Have employed above-mentioned scheme, cutter head and cutter detachable, when needs change cutter time, cutter without the need to disassembling from lathe cutter saddle, but directly replacing cutter head, time saving and energy saving; As long as owing to changing cutter head during tool changing, decrease quantity and the quantity in stock of cutter, be convenient to the management of cutter, save the cost of manufacture of cutter.
Accompanying drawing explanation
Fig. 1 is the utility model decomposition texture schematic diagram;
Fig. 2 is the top view of cutter head in Fig. 1;
In figure, 1 is handle of a knife, and 2 is cutter head, and 3 is bolt, and 4 is locking breach, and 5 is bolt hole, and 6 is nut, and 7 is axially extending bore, and 8 is spherical hollow space, and 9 is locking section, and 10 is changeover portion, and 11 for stepping down breach, and 12 is counterbore.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
See Fig. 1,2, the removable cutter of a kind of cutter head, comprise handle of a knife 1 and cutter head 2, described cutter head is provided with the connecting portion be connected with the head end of handle of a knife, connecting portion is provided with the locking breach 4 passed through for bolt 3, the head end of described handle of a knife is provided with the accommodating cavity of accommodating connecting portion, the axis of accommodating cavity and the axis collinear of handle of a knife, the sidewall of head end offers the bolt hole 5 running through accommodating cavity, the axis of bolt hole and the intersect vertical axis of accommodating cavity, described cutter head is fixedly connected with the head end of handle of a knife by bolt and nut 6.
Described accommodating cavity comprise head end and the handle of a knife coaxial line being arranged on handle of a knife axially extending bore 7, be arranged on the spherical hollow space 8 be communicated with axially extending bore in head end, described bolt hole runs through spherical hollow space, and the centre of sphere of described spherical hollow space is positioned on the intersection point of the axis of bolt hole and the intersect vertical axis of axially extending bore; Described connecting portion comprises laterally zygomorphic two parts, the laterally zygomorphic two parts of connecting portion include the locking section 9 being placed in centre of sphere cavity and the changeover portion 10 being placed in axially extending bore, between two changeover portions, Formation cross-section is the breach 11 of stepping down of isosceles triangle, forms the locking breach passed through for bolt between two locking sections.
The two ends of described bolt hole are provided with counterbore 12, and head and the nut of bolt are placed in counterbore, avoid the head of bolt and nut to exceed the sidewall of knife bar, and then normally may to work the impact that may cause on cutter.
When cutter head and knife bar assembling, because connecting portion is provided with step down breach and locking breach, when cutter head is inserted in accommodating cavity from the aperture of axially extending bore, laterally zygomorphic two parts of connecting portion can be close to each other, so that connecting portion can be inserted in accommodating cavity, connecting portion is inserted into after in accommodating cavity, and bolt passing through bolt hole is connected with nut with locking breach, and cutter head is just fixed together with knife bar.
Accommodating cavity comprises spherical hollow space and axially extending bore, the sphere diameter of spherical hollow space is greater than the diameter of axially extending bore, connecting portion comprises locking section and changeover portion, after cutter head being fixedly connected with knife bar by bolt and nut, locking section is agreed with mutually with spherical hollow space, changeover portion and axially extending bore are to agreeing with, and cutter head can not depart from.The spherical setting of cavity and agreeing with mutually with locking section and spherical hollow space, spherical hollow space and lock section sphere-contact, sphere-contact is convenient to the accommodating cavity that cutter head enters or departs from knife bar.
Cutter head of the present utility model and cutter detachable, when needs change cutter time, cutter without the need to disassembling from lathe cutter saddle, but directly replacing cutter head, time saving and energy saving; As long as owing to changing cutter head during tool changing, decrease quantity and the quantity in stock of cutter, be convenient to the management of cutter, save the cost of manufacture of cutter.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
