Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiments of Ben Fanming, rather than the embodiment of whole.It is based on
The principle of the present invention, method and effect and embodiment, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belongs to the scope of protection of the invention.
Embodiment one,
A kind of support type camshaft boring grab, it includes base 1, support member 2, fixture 3 and hold down gag 4, wherein,
The support member 2 includes the first support member 21, the second support member 2222 and the 3rd support member 2323, three support members
It is sequentially fixed at from front to back on base 1；Wherein, the upper surface level of the base 1；It is at this place and new in whole this practicality
In type, described refers in front and back, and along the axis direction of camshaft 5, the drill end of camshaft 5 is front, if the two of camshaft 5
End drills, then it can be assumed that either end is used as front.
The fixture 3 includes the first fixture 31, the second fixture 32 and the 3rd fixture 33, wherein, first fixes
Part 31 is fixed on the first support member 21, and the second fixture 32 is fixed on the second support member 22, and the 3rd fixture 33 is fixed on
On 3rd support member 23；Wherein,
First fixture 31 and the 3rd fixture 33 are respectively provided with spacing space, and it includes left fixed arm 35, right fixed arm
36 and positioning limiting fixator pedestal 34, wherein, left fixed arm 35 is connected and shape with right fixed arm 36 by positioning limiting fixator pedestal 34
Into spacing space, the width in the spacing space is gradually reduced from top to bottom；In the present embodiment, fixture is integrally formed
Global facility, naturally it is also possible to assembled by three different parts in other embodiments.The spacing space from
Top to bottm is gradually reduced, then the spacing space can accommodate the camshaft 5 with the different diameters of axle, when the different diameters of axle of its receiving
During camshaft 5, the camshaft 5 is different from the contact position of left fixed arm 35, right fixed arm 36.Thus, whole folder can be caused
Tool device has preferably compatibility, improve its range of application, it is to avoid the replacement of unnecessary frequently component.
There is second fixture 32 rotation to stop space, and it includes that left stop arm, right stop arm and rotation stop fixture
Pedestal, wherein, left stop arm stops that fixture pedestal is connected and forms rotation and stops space with right stop arm by rotation, described
Rotation stops that space is rectangle；In the present embodiment, second fixture 32 is integrally formed overall structure, specifically should
With in, technical staff is it is of course possible to being interfixed as the second fixture 32 using multiple different parts as needed.The rotation
Turn to stop that space is rectangular, it primarily serves the purpose of the rotation for preventing camshaft 5, facilitates the drilling of camshaft 5.It at least may be used
To realize the function using one of the following two kinds mode, in the first situation, a certain section of the middle part of camshaft 5 to be processed
Section is rendered as polygon, and for example its middle part has one section of section square or regular hexagon, and now, the section at least has
There are a larger width and a less width, when from the second suitable fixture 32 so that its rotation stops at the width in space
Between the larger width and the less width, then 5 sections of the camshaft can be caused just to enter the rotation and to stop space and nothing
There is further rotation in method, especially when the rotation stops that the width in space is equal or slightly larger than the condition of the less width
Under, the rotation barrier effect is more notable.In this case, can be by a cam at the middle part of camshaft 5 as this
In rotation stop space, wherein, the rotation stops that the width in space is equal or slightly larger than the base radius of the cam.This second consolidate
Determine part 32 realize to camshaft 5 it is circumferentially fixed after, it can also reduce camshaft 5 by the vibrations of camshaft 5 effectively everywhere
Vibrations and amplitude, improve drilling precision.Certainly, in specific application, can arrange multiple second fixtures 32 and
The second support member 22 being engaged with the second fixture 32, reaching reduces the effect of amplitude.
The hold down gag 4 includes that one there is the hydraulic means of above-below direction telescopic arm, one to be connected with the hydraulic means
Rotary apparatuss and compressor arm 41, the hydraulic means and choose to install device and be fixed on support member 2, the upper end of the telescopic arm is consolidated
A fixed linking arm, the upper end of the linking arm has screw thread and is fixed on compressor arm 41.Thus, the hydraulic means and rotating dress
Putting can be connected with the control system of lathe, realize automatically controlling clamping and discharging.When camshaft 5 is placed into into the folder
When on tool device, the shaft portion between cam can enter spacing space and be propped up by the first fixture 31 or the 3rd fixture 33
Support, intermediate portion can enter rotation and stop space and realize circumferential fixation.Now, rotary apparatuss rotate the compressor arm
41 so that one end of compressor arm 41 is rotated to the first fixture 31 or the top of the 3rd fixture 33, hydraulic means causes telescopic arm
Shrink, drive compressor arm 41 to move downward and apply a downward power to camshaft 5, assist the fixation to camshaft 5.
Now, camshaft 5 is fixed, and compressor arm 41 is conducted to camshaft 5 and so that camshaft 5 is in close contact with fixture 3, and this is tight
Frictional force produced by contact etc. can effectively realize fixation of the camshaft 5 in axial and circumferential.After the completion of drilling, hydraulic pressure
Device causes telescopic arm to extend, and drives compressor arm 41 to depart from camshaft 5 and away from the first fixture 31 and the 3rd fixture 33,
Rotary apparatuss cause the compressor arm 41 to rotate, and the angle of rotation is optimal with 90 °.At this point it is possible to so that the compressor arm 41 is thorough
Bottom departs from the top of camshaft 5, facilitates picking and placeing for camshaft 5.
The back side of the base 1 has groove 11, and the slotted hole 12 of fore-and-aft direction is offered in groove；The support member 2
Bottom be provided with screw, fixed screw coordinates the fixation for realizing base 1 and support member 2 with slotted hole and screw.Thus, can be with
According to the cam installation situation of specific camshaft 5, position of the support member 2 among slotted hole is adjusted by fixed screw, made
Obtain the boring grab of camshaft 5 and there is certain compatibility.Between the nut and slotted hole of screw, packing ring 1 is provided with, to reach
Into more closely combining.
Wherein, in a kind of specific application, the hold down gag does not include rotary apparatuss, and it is by being fixed on support member
