Abstract
The invention belongs to metal cutting process cutting-tool engineering fields, more particularly to a kind of thread handle drill bit of cylinder positioning, including knife handle and cutter head, the knife handle and cutter head coaxial arrangement, it is characterized by: being fastening thread on the knife handle periphery, the interconnecting piece of knife handle and cutter head is provided with columned positioning cylinder, the diameter of the positioning cylinder is not less than the major diameter of fastening thread, positioning cylinder is added in the present apparatus, it is connected and is fastened by screw thread pair between drill bit and drilling attachment, the top of drilling attachment is set as hole, the inner surface of hole is in contact with the periphery of positioning cylinder on drill bit, face is in contact with face between the two, the machining accuracy on cylindrical surface in technique for it is higher than the machining accuracy of screw thread, it is easier to be guaranteed, pass through the positioning of positioning cylinder, the straightness of this drill bit is more preferable, the precision of punching is higher.
Description
Technical field
The invention belongs to metal cutting process cutting-tool engineering fields, and in particular to a kind of thread handle drill bit of cylinder positioning.
Background technique
Drill bit is boring bar tool general in industry at present, and drill bit is mainly made of knife handle and cutter head, and wherein knife handle is most normal
The shape seen is circle handle and square handle, and the knife handle of both shapes is by the frictional force between drilling attachment and knife handle outer surface
Drilling tool is clamped, the drilling precision of this method of clamping is high.
It is provided with fastening thread on the knife handle periphery for having a kind of drill bit in industry, is led between fastening thread and drilling attachment
Cross screw thread pair and be attached connection, the connection area of drillstock and drilling attachment is bigger, so between the two it is spacious it is dynamic greatly reduce, mention
The high machining accuracy in hole.But in the process of screw thread, the precision of screw thread is easy to happen biggish variation, and the company of screw thread
There are many point or face in termination process, be in contact, interfered, and therefore, the drilling precision of this drill bit is by accuracy of thread and screw thread
Secondary influence is very big.
Summary of the invention
A kind of thread handle drill bit of cylinder positioning provided it is an object of the invention to overcome the deficiencies in the prior art.
The present invention is implemented as follows: a kind of thread handle drill bit of cylinder positioning, including knife handle and cutter head, the knife handle
It is coaxially disposed with cutter head, it is characterised in that: be fastening thread, the interconnecting piece setting of knife handle and cutter head on the knife handle periphery
There is columned positioning cylinder, the diameter of the positioning cylinder is not less than the major diameter of fastening thread.
It advanced optimizes, is provided with wearing layer on the periphery of the positioning cylinder.
It advanced optimizes, the material of the wearing layer is one of hard chromium layers or carburized layer.
Compared with prior art, the beneficial effects of the present invention are: in process due to screw thread, the machining accuracy of screw thread
The limitation of Screw thread process method is received, accuracy of screw machining is not high, so only tightening with fastening thread, the straightness of drill bit is not
It is good.Positioning cylinder is added in the present apparatus, is connected and is fastened by screw thread pair between drill bit and drilling attachment, the top of drilling attachment is set
It is set to hole, the inner surface of hole is in contact with the periphery of positioning cylinder on drill bit, and face is in contact with face between the two, cylinder
The machining accuracy in face in technique for it is higher than the machining accuracy of screw thread, it is easier to be guaranteed, pass through determining for positioning cylinder
Position, the straightness of this drill bit is more preferable, and the precision of punching is higher, significantly improves the clamp precision and drilling processing essence of drill bit
Degree.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the present apparatus.
Fig. 2 be the present apparatus in conjunction with drilling attachment when status diagram.
Specific embodiment
Embodiment 1, as depicted in figs. 1 and 2, a kind of thread handle drill bit of cylinder positioning, including knife handle 1 and cutter head 2, it is described
Knife handle and cutter head coaxial arrangement, be fastening thread 3, the interconnecting piece setting of knife handle 1 and cutter head 2 on 1 periphery of knife handle
There is columned positioning cylinder 4, the diameter of the positioning cylinder is greater than the major diameter of fastening thread.On the periphery of positioning cylinder 4
It is additionally provided with wearing layer, the material of wearing layer is hard chrome.
The above description is only a preferred embodiment of the present invention, is not intended to limit the invention, for those skilled in the art
For member, the invention may be variously modified and varied, all within the spirits and principles of the present invention, made any modification,
Equivalent replacement, improvement etc., should all be included in the protection scope of the present invention.
Claims (3)
1. a kind of thread handle drill bit of cylinder positioning, including knife handle and cutter head, the knife handle and cutter head coaxial arrangement, feature
