Further, the inner sidewall of the venthole offers inner concave 8 in its end, in order to which user is in support of taking
When covering 4, very easily support sleeve 4 can be taken out from through-hole by inner concave 8, and support sleeve 4 is avoided to be taken from through-hole
The phenomenon that shaking is generated when out.
Wherein, as preferred mode, the curved surface of above-mentioned inner concave 8 is arc surface.
Further, for cooperating the end of the slot bore hole 19 to offer cooperation opening 9 on the support sleeve 4, and
The size of the cooperation opening 9 is greater than the track route of cutter.
Further, the outer wall of above-mentioned support sleeve 4 axially at least offers an air channel 21 along it.To prevent thin wall
If causing air containment because fitting closely between body part 2 and support sleeve 4, so that the phenomenon that forming negative pressure, to lead
Cause occurs being difficult to the problem of support sleeve 4 is taken out and is subsequently inputted into inside parts of thin-wall casing 2.
Specifically, offering a plurality of lead to along its circumferencial direction equidistant interval on the outer wall of the support sleeve 4 in the present embodiment
Air drain 21, some areas and parts of thin-wall casing 2 to avoid the outer wall of support sleeve 4 are adjacent to and the phenomenon that being difficult to plug occur.
As a kind of wherein preferred mode, only to offer three along its circumferencial direction on the outer wall of support sleeve 4 in the present embodiment
Illustrate for air channel 21.
Further, the inner wall of the connecting hole is equipped with screw thread, for passing through bolt when the insertion end cooperates and is inserted into
It is threadedly coupled.In a manner of being connected through a screw thread, guarantee the connection tightness between parts of thin-wall casing 2 and pedestal.
In more detail, the connecting hole includes: the annular for opening up and matching on the base and with the insertion end
Locating slot 10, is provided with the annular positioning groove 10 at the threaded hole 11 being provided in the groove bottom of the annular positioning groove 10
In groove bottom and around the annular spacing groove 12 of the threaded hole 11 setting；
The insertion end includes: round boss compatible with the annular positioning groove 10, is arranged in the round boss
It is upper to be used to cooperate the round clasp for being inserted into the annular spacing groove 12, the setting round clasp interior for cooperating the insertion spiral shell
Insertion section in pit 11；
Wherein, the pin hole for being connected to the threaded hole 11 is offered on the insertion section.
It follows that by round boss and annular positioning groove 10, round clasp and annular spacing groove 12, threaded hole 11 with
Engaging between insertion section, enable the insertion end of parts of thin-wall casing 2 insertion connecting hole, firmly link together and
It is not easy to be pulled out.
Further, the installation position further include: open up the second connecting hole 18 on the base, and the first connecting hole 17
0.05mm is differed with the diameter dimension size of the second connecting hole 18, to meet the ruler of part parts of thin-wall casing 2 in practical set
It is very little to occur slight inconsistent and lead to not the phenomenon that assembling.
In addition, it is noted that the parts of thin-wall casing 2 in the present embodiment is section in circle as preferred mode
The part of shape can also be actually the section of the other shapes such as rectangle, abnormity, correspondingly, above-mentioned first connecting hole and second
The preferably circular section holes of connecting hole can also be actually the section holes of the other shapes such as rectangle, abnormity, and the present embodiment is to this
Specifically restriction and explanation are not made.
The second embodiment of the utility model provides a kind of fixture for parts of thin-wall casing processing, and the of the application
Two embodiments are the further improvements to above-described embodiment, it is improved in that in the present embodiment, fixture further include: set
Set the positioning plate 3 matched on pedestal with installation position；Locating piece 7 on positioning plate 3 is set, for cooperating insertion thin wall
In the slot bore hole 19 of body part 2, and the head end of locating piece 7 is exposed from the through-hole of parts of thin-wall casing 2.
It can be seen from the above content that since the application fixture is passing through the fixed parts of thin-wall casing in installation position on its pedestal
While 2, so that the locating piece 7 on setting positioning plate 3 is inserted into the slot bore hole 19 of parts of thin-wall casing 2, and from thin-wall case
It is exposed in the through-hole of part 2, thus by means of locating piece 7 is exposed from the through-hole of parts of thin-wall casing 2, so that
It, can be by locating piece 7 to 2 slot bore hole of parts of thin-wall casing such as when vertical boring mill is processed during following process
19 limit, so that parts of thin-wall casing 2 can be quickly adjusted to rigging position according to locating piece 7 by staff, and being based on should
Locating piece 7 is used as positioning datum point, so as to easily design corresponding cutter in track route, to substitute artificial
Mode is inserted into the through-hole of the slot bore hole 19 of parts of thin-wall casing 2, and from the inside of slot bore hole 19, the cell wall to slot bore hole 19 is carried out
It is accurately positioned processing, so that processing efficiency can be improved, reduces processing cost, and can preferably avoid leading due to using artificial
The interior external groove sidevall of processing pit bore hole 19 is caused asymmetric phenomenon occur.In addition, simplifying setting for fixture by above structure
Meter, improves the assembly efficiency of fixture.
Specifically, in the present embodiment, above-mentioned positioning plate 3 is mainly by being removably arranged level on the base
Portion is constituted with horizontal part vertical portion connected vertically.Wherein, locating piece 7 is removably arranged in the vertical portion, and
The axial direction of the locating piece 7 is parallel with the horizontal part.When in order to process, positioning datum point is used as by the locating piece 7, and
After designing corresponding cutter track route, locating piece 7 can be removed from positioning plate 3, protrude into thin-wall case in order to cutter
In the through-hole of part 2, the cell wall of slot bore hole 19 is processed inside through-hole.
In detail, installation position includes: the first connecting hole 17 opened up on the base.Also, the first connecting hole 17
Shape is adapted with the insertion end of parts of thin-wall casing 2.So that guaranteeing the X in the horizontal plane of parts of thin-wall casing 2, Y-direction
The freedom degree of freedom degree and Z-direction is effectively limited.
Further, above-mentioned fixture further include: open up on the base and for assembling the dress for matching the horizontal part
Slot allocation 16, and the groove face of the fitting groove 16 is used to closely be adjacent to the surface of the horizontal part, to prevent positioning plate 3 from assembling
When cause the height of locating piece 7 the phenomenon that deviations occur as datum mark because of the surface irregularity of pedestal.
Above embodiments are only to illustrate the technical solution of the utility model and non-limiting, reference only to preferred embodiment pair
The utility model is described in detail.Those skilled in the art should understand that can be to the technology of the utility model
Scheme is modified or equivalent replacement, without departing from the spirit and scope of the technical scheme of the present invention, should all cover in this reality
With novel scope of the claims.
