Abstract
The utility model discloses an inner hole boring cutter rod for a casing head. The inner hole boring cutter rod comprises a boring cutter rod body, two cutter mounting holes, cutter positioning holes and a cutter seat, wherein the boring cutter rod body is parallel to the cutter seat, and the axial line of the cutter seat is parallel to the axial line of the boring cutter rod body; the cutter mounting holes are formed in the cutter seat; the cutter positioning holes are formed in the cutter seat; the surface of the boring cutter rod body is provided with a clamping surface; the boring cutter rod body is a rotating body, and the surface of the rotating body is provided with a clamping surface; the cutter seat is elliptical; the extending line of the elliptical virtual axis of the cutter seat passes through the axial line of the boring cutter rod body; the relatively flat edge of the cutter seat is attached to one edge of the boring cutter rod body; the two cutter mounting holes are formed in the relatively flat edge of the cutter seat in axial direction of the cutter seat; the cutter positioning holes are formed in the positions, where the cutter mounting holes are perpendicular to the side surface of the cutter seat; threads are formed in the cutter positioning holes, and the cutter positioning holes are communicated with the cutter mounting holes. According to the utility model, the elliptical cutter seat space is small, so that inner hole processing can be completed for one time through clamping; the labor strength is reduced, and the survival rate is increased; furthermore, by adopting the elliptical cutter seat, the inner hole boring cutter rod for the casing head is high in intensity and long in service life.
Description
Technical field
The utility model relates to a kind of metal working tool, relates in particular to a kind of casing head inner hole boring tool bar.
Background technology
When tradition machined field processing larger diameter endoporus intersection, conventionally adopt twice clamping to process, the labour intensity but also the multiple clamping that so not only increase workman affect machining accuracy.Now also have cutter once mounting on circular boring bar, but at the bottom of less its intensity of restriction boring cutter bar size due to outer aperture, the life-span is short.
Utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of casing head inner hole boring tool bar.
The utility model solves the technical scheme that its technical problem adopts: described casing head inner hole boring tool bar, comprise boring cutter bar body, Cutting tool installation manner hole, hole, cutter positioning, tool rest, and boring cutter bar body and tool rest, tool rest axis is parallel with boring cutter bar body axis.Described tool rest is provided with Cutting tool installation manner hole, and tool rest is also provided with hole, cutter positioning, and hole, cutter positioning is counterbore.The surface of described boring cutter bar body is provided with clamping face, and clamping face is plane and is symmetricly set on boring cutter bar body both sides.Described boring cutter bar body is that revolving body and revolving body surface are provided with clamping face, and tool rest is oval, and its oval imaginary axis extended line is through boring cutter bar body axis, and the more flat one side of tool rest and boring cutter bar body are fitted on one side.Oval-shaped tool rest is bore hole under can the prerequisite of proof strength not only, and can further expand bore hole scope and prevent that boring bar from scratching hole wall.Described Cutting tool installation manner hole is arranged on the more flat side of tool rest, Cutting tool installation manner hole is two and along the setting of tool rest axis direction, tool rest side and upright position, Cutting tool installation manner hole are provided with hole, cutter positioning, be provided with screw thread and hole, cutter positioning and be communicated with Cutting tool installation manner hole in hole, cutter positioning.
The beneficial effects of the utility model are: owing to adopting, oval tool rest space is little can complete by clamped one time endoporus processing to the utility model, reduces work, improves survival rate, and it adopts oval-shaped tool rest intensity high, and the life-span is long.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the side structure schematic diagram of a kind of casing head inner hole boring tool of the utility model bar;
Fig. 2 is the end face structure schematic diagram of a kind of casing head inner hole boring tool of the utility model bar.
Wherein: 1. clamping face, 2. boring cutter bar body, 3. tool rest, 4. hole, cutter positioning, 5. Cutting tool installation manner hole.
Detailed description of the invention
Below in conjunction with an embodiment of accompanying drawing narration, the utility model is described in further detail.
Embodiment: in the drawings, described casing head inner hole boring tool bar, comprises boring cutter bar body 2, Cutting tool installation manner hole 5, hole, cutter positioning 4, tool rest 3, boring cutter bar body 2 and tool rest 3, tool rest 3 axis are parallel with boring cutter bar body 2 axis.Described tool rest 3 is provided with Cutting tool installation manner hole 5, and tool rest 3 is also provided with hole, cutter positioning 4, and hole, cutter positioning 4 is counterbore.The surface of described boring cutter bar body 2 is provided with clamping face 1, and clamping face 1 is for plane and be symmetricly set on boring cutter bar body 2 both sides.Described boring cutter bar body 2 is for revolving body and revolving body surface are provided with clamping face 1, and tool rest 3 is oval, and its oval imaginary axis extended line is through boring cutter bar body 2 axis, and the more flat one side of tool rest 3 and boring cutter bar body 2 are fitted on one side.Oval-shaped tool rest 3 is bore hole under can the prerequisite of proof strength not only, and can further expand bore hole scope and prevent that boring bar from scratching hole wall.Described Cutting tool installation manner hole 5 is arranged on the more flat side of tool rest 3, Cutting tool installation manner hole 5 is two and along tool rest 3 axis direction settings, tool rest 3 sides and 5 upright positions, Cutting tool installation manner hole are provided with hole, cutter positioning 4, be provided with screw thread and hole, cutter positioning 4 and be communicated with Cutting tool installation manner hole 5 in hole, cutter positioning 4.
When work, boring cutter is arranged in the Cutting tool installation manner hole 5 on tool rest 3, bolt screws in hole, cutter positioning 4 boring cutter is fixed on tool rest 3, and bar body clamping, on knife rest, stretches into endoporus by boring cutter and carries out bore hole to appropriate location.
The technical program adopts that oval tool rest 3 spaces are little can complete by clamped one time endoporus processing, reduces work, improves survival rate, and it adopts oval-shaped tool rest 3 intensity high, and the life-span is long.
The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; 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.
