Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
Embodiment 1
As shown in figure 1, axial flow blower aluminium alloy casing die casting, average wall thickness 3mm, local thinnest part only 1.5mm.The machine
Shell die casting part needs its bearing chamber endoporus of turning Deep 12, seam Depth 8 and end face（Ensure size 25
）.According to chuck（Even soft pawl）The outer rim of 48 holes of Φ 81 or the inner edge of 113 holes of Φ 82 are clamped, then is released after clamping force, work
The reply of elastic deformation can occur for part, and lose precision, and the non-self-centering of chuck, be unsuitable for the production in enormous quantities of product.
Thus analyze, it is necessary to seek a kind of mode of axial compression.So using with lower clamp：
A kind of express dispatch type casing vehicle clamper, including：
Clamp body 1, as shown in Figure 4 and Figure 5, it has chuck body 11 and outward extended flange from chuck body 11
12, workpiece coordinates with the gap of flange 12；Specifically, in order to ensure the outer rim and casing of flange 12 The inner edge of hole 82 has
Enough rotation leeway, flange 12 is made up of some circular arc blocks 121 circumferentially arranged, is four circular arc blocks in the present embodiment
121, each outside of circular arc block 121 has the arc surface coordinated with workpiece gap., can be by original complete annulus in processing
Shape flange retains four required circular arc blocks 121, and remainder is milled, as shown in Figure 2 and Figure 4.
Above-mentioned fixture also includes wedge block 2, as shown in fig. 6-7, from two wedge blocks 2, specific number in the present embodiment
Can root need selection.Wedge block 2 can be fixed in chuck body 11, particularly, and wedge block 2 has fixed part 21 and tight lock part
22, it is fixed in chuck body 11 by fixed part 21, and fixed part 21 is provided with corresponding position in the first mounting hole 41, chuck body 11
The second mounting hole 42 has been installed, has been consolidated wedge block 2 through the first mounting hole 41 and the second mounting hole 42 using the grade of screw 4 fastener
In chuck body 11.And above-mentioned wedge block 2 one side relative with chuck body 11 is inclined-plane 221, the inclined-plane 221 is particularly located at lock
Tight portion 22 bottom, edge of the workpiece away from flange 12 can be locked in the inclined-plane 121 and the fixture certainly by the inclined-plane 221
Between body 11, in order to ensure self-locking effect, the oblique angle of inclined-plane 221 is taken as 3 ゜ in the present embodiment, and specific angle of inclination can be according to institute
Folder workpiece is adjusted.By Fig. 2 and Fig. 3 it can also be seen that, wedge block 2 is oppositely arranged, positioned at casing（That is workpiece）The flange of outer rim two
Cubic two corresponding positions.
When rotational workpieces in one direction, edge of the workpiece away from flange 12 can be locked by inclined-plane 221, now workpiece
Direction of rotation is to screw direction；When rotating in mutually opposite directions workpiece, edge of the workpiece away from flange 12 can be released by inclined-plane 221
The state of locking.
During clamping, the inner edge of 113 holes of casing Φ 82 is inserted in the flange 12 of clamp body 1（Four circular arc blocks as shown in Figure 4
121）, complete gap and coordinate positioning, rotate clockwise casing, then cubic two corresponding positions of the flange of casing outer rim two enter wedging simultaneously
The chamfered region of block 2（Space between inclined-plane 221 and chuck body 11）And contacted with inclined-plane 221 until tightening, now i.e.
Into self-locking state, it is achieved thereby that changing the direction of clamping force, the traditional radial clamping of change is axial compression.When starting lathe
When carrying out turnery processing, due to the direction of main cutting force suffered by casing bearing hole wall, with casing to screw direction consistent（I.e. to workpiece
Main cutting force direction it is identical with screwing direction）, so casing will not loosen in turning process（Only can more car it is tighter）.Work as car
Cut and finish, casing is rotated counterclockwise by hand, make the diagonal clamping face of two flanges top two while exiting wedge block inclined-plane locking area, axle
Released therewith to thrust, casing is easily removed.The turning of next casing can similarly be entered.
Embodiment 2
As shown in figure 8, the workpiece clamped by the present embodiment is the eccentric element of unsuitable radial clamping：Centrifugal blower volute 5,
Now need to be processed its bearing hole, the centrifugal blower nest shell 5 has three installing handles 51 extended outward.As Fig. 9-10 institute
Show, fixture is made up of clamp body 6 and three wedge blocks 7 in the present embodiment, clamp body 6 have chuck body and from chuck body to
The flange 61 of outer extension, three wedge blocks 7 are evenly distributed.Wedge block 7 is in convex in the present embodiment, and it has fixed part 71
With tight lock part 72, the function of fixed part 71 and tight lock part 72 is same as Example 1, and fixed part 71 is also by screw and clamp body 6
It is fixed.Inclined-plane also is located at the bottom of the tight lock part 72 of wedge block 7, and locking centrifugal blower nest can be fixed between inclined-plane and clamp body 6
Shell 5.
As shown in figs. 9-10, during installation, centrifugal blower nest shell 5 is first enclosed on the outside of flange 61, coordinates with its gap, Ran Houxuan
Turn, three installing handles 51 on centrifugal blower nest shell 5 respectively enter the sky between the inclined-plane and chuck body 6 of three wedge blocks 7
Between, with the progress of rotation, installing handle 51 and contact of incline plane are simultaneously locked, and now centrifugal blower nest shell 5 is fixed, and is machined
Afterwards, opposite direction rotating centrifugal blower fan nest shell 5, releases coupling mechanism force, unloads workpiece.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these improve and deformed
Also it should be regarded as protection scope of the present invention.
