Specific embodiment
Below with reference to the attached drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
It describing clear, perfectly, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all
Embodiment, in the absence of conflict, the features in the embodiments and the embodiments of the present application can be combined with each other, below will
This utility model is described in detail with reference to attached drawing and in conjunction with the embodiments.
As shown in Figure 1, turning machine shell positioning fixture provided by the embodiments of the present application, it can be to 1 upper section portion of turning machine shell
Divide, bottom all clamps.Fixation kit includes upper portion fixation kit clamp body 2, bottom fixation kit 3.Bottom fixation kit
It is fixed on pedestal 4.Since the diameter of turning machine shell 1 is longer, find in actual operation, if fixed only with bottom
Mode, turning machine shell 1 are easy to shake in process, will affect the precision of the processing of turning machine shell 1.
As shown in Fig. 2, the upper portion fixation kit of turning machine shell 1 includes: clamp body 2, is fixed on clamp body
Clamping component.Clamping component includes vee-block 21, V-arrangement positioning seat 22 and side locating piece 23；The control clamping component operation
Pressing device includes auxiliary hold-down cylinder 24 and clamping lever 25；Vee-block 21 is fixed on V-arrangement positioning seat 22, and V-arrangement positioning seat 22 is logical
It crosses side locating piece 23 and clamp body 2 is fixed, clamping lever 25 is oppositely arranged with vee-block 21, auxiliary hold-down cylinder 24 and compression thick stick
Bar 25 is connected, and assists hold-down cylinder 24 that clamping lever 25 is driven to act, and turning machine shell 1 is clamped in clamping lever 25 and V-arrangement
Between block 21.
As shown in Fig. 2, the clamping component of 1 upper portion of turning machine shell further includes height adjustment pad piece 26 and side tune
Whole gasket 27.Height adjustment pad piece 26 is arranged among V-arrangement positioning seat 22 and clamp body 2, and side adjusts gasket 27 and is arranged in V-arrangement
Among positioning seat 22 and side locating piece 23, by adjusting gasket, displacement of the adjustable vee-block 21 in X-axis, Y direction,
Keep fixed position more steady accurate.
As shown in figure 3,1 bottom fixation kit of turning machine shell includes calming down plane 31, centralized positioning pin 32 is angular fixed
Plane 33 is sequentially fixed on pedestal 4.Wherein, the central axes of centralized positioning pin 32 are overlapped with the central axes of turning machine shell 1,
The contact surface of centralized positioning pin 32 and transition and shell has done four side cutting process, every to remain a bit of circular arc on one side.Relatively
Common Cylindrical locating pins, so processing is advantageous in that, during turning machine shell 1 is fixed, it is easier to
Into turning machine enclosure interior, it is not easy to cause breakage to turning machine shell 1 in contact process.Four retained in cutting process are small
Section radian makes the contact point inside centralized positioning slightly 32 and turning machine shell 1 become more, is more convenient for fixing.In addition, angularly positioning
Diamond shape trimming processing is done in 1 end that face 33 is contacted with turning machine shell 1.Angular positioning surface 33 is located at the one of centralized positioning pin 32
Side, it is further to turning machine housing bottom to be reinforced.Plane 31 of calming down is located at the other side of centralized positioning pin 32, against steering
Casing body 1 is fixed by screw with the side for turning to casing 1.
In a kind of embodiment of the application, fixture is divided into two steps to the fixation of turning machine shell 1.
(1) fixation of 1 bottom of turning machine shell.Centralized positioning pin 32 is fixed on pedestal 4, calms down plane 31, angular fixed
Centrally disposed 32 left and right sides of positioning pin in position 33, is also secured on pedestal 4.32 one end of centralized positioning pin is fixed on the base,
Center axis thereof is overlapped with the center line axis of turning machine shell 1.As shown in figure 4, Fig. 4 is the main view of centralized positioning pin 32, Fig. 5
It is the top view of centralized positioning pin 32.It is seen from fig 5 that one end that centralized positioning pin 32 is directly contacted with turning machine shell 1
