Description
Technical field
The present invention relates to machinery design field, particularly relate to a kind of drilling and milling machine and handle crank.
Background technology
Various different driving parts is generally used on lathe, when lathe needs to realize various different rotating ratio,
It is typically to move the position of driving parts, so that different driving parts is in engagement, at mobile driving parts
Time need to use the device of crank, traditional crank many employings straight pin carries out circumferentially fixed with rotary shaft, strong due to pin
Spending relatively low, it is inevitable less that what it can bear pulls moment, and it is unreliable that crank body is fixed, and traditional crank bar mostly is straight-bar, leads
Causing crank and pull the most smooth and easy, troublesome poeration, traditional crank rod-shape mostly is cuboid, and weight is relatively big, therefore designs one
Simple in construction, that bears pulls moment greatly, and straight pin installation and removal are convenient, and crank body is fixing reliable, and crank body is pulled smooth and easy,
Easy to operate, the intensity of crank bar is high, lightweight, rational in infrastructure, and the drilling and milling machine manipulation crank saving material seems the most necessary.
Summary of the invention
The purpose of the present invention is contemplated to overcome that traditional crank bears that to pull moment little, troublesome poeration, crank bar weight
Measuring big defect, devise a kind of drilling and milling machine and handle crank, simple in construction, crank body is fixing reliable, easy to operate, crank bar
Intensity is high, lightweight.
Solve the technical problem that required by the present invention and can be achieved through the following technical solutions:
A kind of drilling and milling machine handles crank, and including crank body, installing hole, described crank body is a cylinder, and its center is drilled with
Described installing hole, also includes pin-and-hole, crank bar, cylindrical hole, holding end, is laterally machined with described pin-and-hole, institute in described installing hole
Stating and use described crank bar to connect between crank body and described holding end, the structure of described holding end is cylinder, and its center adds
Work has described cylindrical hole, and stick is i.e. arranged in described cylindrical hole.
It is machined with keyway in the described installing hole of described crank body, between described crank body and rotary shaft, uses key transmission.
The described oblique outside of pin-and-hole level is arranged, and uses straight pin to fix between described crank body and rotary shaft.
Described crank bar is warp architecture.
The cross section of described crank bar is concave shape.
Owing to have employed above technical scheme, present invention have the advantage that
The drilling and milling machine using crank body, installing hole, pin-and-hole, crank bar, cylindrical hole, holding end to combine designed is handled and is shaken
, it being machined with keyway in the installing hole of crank body, between crank body and rotary shaft, use key transmission, simple in construction, that bears pulls
Kinetic moment is big, and the oblique outside of pin-and-hole level is arranged, and uses straight pin to fix between crank body and rotary shaft, straight pin peace installation and dismantling
Unloading conveniently, fixing reliable, crank bar is warp architecture, will not occur and showing that other part on lathe is interfered when rotating crank body
As, crank body is pulled smooth and easy, easy to operate, and the cross section of crank bar is concave shape, and this structure makes the intensity height of crank bar, weight
Gently, rational in infrastructure, save material.

Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below knot
Conjunction is specifically illustrating, and the present invention is expanded on further.
A kind of drilling and milling machine handles crank, including crank body 1, pin-and-hole 2, installing hole 3, crank bar 4, cylindrical hole 5, holds end 6,
Crank body 1 is a cylinder, and its center is drilled with installing hole 3, is laterally machined with pin-and-hole 2, crank body 1 and holding end 6 in installing hole 3
Between use crank bar 4 connect, hold end 6 structure be cylinder, its center is machined with cylindrical hole 5, and stick is i.e. arranged on
In cylindrical hole 5, simple in construction, low cost.
Keyway it is machined with in the installing hole 3 of crank body 1, employing key transmission between crank body 1 and rotary shaft, simple in construction,
Bear to pull moment big.
The oblique outside of pin-and-hole 2 level arrange, between crank body 1 and rotary shaft use straight pin fix, straight pin install and
Convenient disassembly, fixing reliable.
Crank bar 4 is warp architecture, the phenomenon interfered with other part on lathe will not occur when rotating crank body 1, shake
Body 1 is pulled smooth and easy, easy to operate.
The cross section of crank bar 4 is concave shape, and this structure makes the intensity height of crank bar 4, lightweight, rational in infrastructure, saves
Material.
Drilling and milling machine disclosed in this invention handles crank, is machined with keyway in the installing hole 3 of crank body 1, crank body 1 with turn
Use key transmission, simple in construction between moving axis, bear to pull moment big, the oblique outside of pin-and-hole 2 level is arranged, crank body 1 with
Using straight pin to fix between rotary shaft, straight pin installation and removal are convenient, and fixing reliable, crank bar 4 is warp architecture, rotates
The phenomenon interfered with other part on lathe will not occur during crank body 1, and crank body 1 is pulled smooth and easy, easy to operate, crank bar 4
Cross section be concave shape, this structure makes the intensity of crank bar 4 high, lightweight, rational in infrastructure, saves material.
The ultimate principle of the present invention, principal character and advantages of the present invention have more than been shown and described.The technology of the industry
Personnel, it should be appreciated that the present invention is not restricted to the described embodiments, simply illustrating this described in above-described embodiment and description
The principle of invention, the present invention also has various changes and modifications without departing from the spirit and scope of the present invention, and these become
Change and improvement both falls within scope of the claimed invention.Claimed scope by appending claims and
Equivalent defines.
