Position bushing B, 6-drill guides, 7-technological datum balls, 8-level frames, 9-vertical stand.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of special punching device of engine accessory power rating wheel chamber casing, including locating template 1, locating template 1
It is obliquely installed and is fixed on L-type right angle fixed frame 2, L-type right angle fixed frame 2 includes level frame 8 and vertical stand 9；
It is opened on the locating template 1 there are two location hole, positioning bushing A4 and fixed is separately installed in two location holes
Position bushing B5, positioning bushing A4 and positioning bushing B5 stretch out outside 1 back side of locating template, positioning bushing A4 and positioning bushing B5 mono-
It rises and is installed with cartridge case body to be processed, there are two holes to be processed on cartridge case body to be processed, and the axle center line position in two holes to be processed is not
It is parallel；
Center position on the locating template 1 between two location holes is further fixed on drill guides 6, and drill bit draws
, just back to title, open that there are two drill bits on drill guides 6 about locating template 1 in the hole to be processed of guiding element 6 and cartridge case body to be processed
Guide hole, each drill guide bores correspond to a hole to be processed；
Drill bit is removably installed on drill guides 6, drill bit passes through drill guide bores, drill bit detachable with rotation axis
It is connected, rotation axis is connected with driving equipment；
The front of the locating template 1, which is additionally provided with, measures cartridge case body to be processed and positioning bushing A4 and positioning bushing B5
Between installation accuracy technological datum ball 7.
The positioning bushing A4 is fixed on by straight pin in the location hole of locating template 1, and positioning bushing B5 is logical
Chamfered edge rhombus pin is crossed to be fixed in the location hole of locating template 1.
It is opened on the cartridge case body to be processed there are two datum hole, positioning bushing A4 and positioning bushing B5 are separately mounted to one
In a datum hole.
The L-type right angle fixed frame 2 is fixed on lathe.
When the cartridge case body to be processed processes a hole to be processed, level frame 8 is fixed on lathe；It is another when processing
When a hole to be processed, L-type right angle fixed frame 2 is overturn, vertical stand 9 is made to be horizontally situated, vertical stand 9 is fixed on lathe
On.
In the present embodiment, fast mounting screw 3 is both provided in the pallet 8 and vertical stand 9.
For installing processed product, supporting surface fits closely locating template 1 with product mounting surface, and level frame 8 and erects
Straight frame 9 is fixedly connected, and is formed a complete device, while being fixed on drill guides 6 on locating template 1, is passed through two
A drill guide bores ensure that the positional precision between two holes to be processed.
Drill guides 6 can replace the drill bit of different model, but replace every time, can ensure that when processing each time
The position in two holes to be processed is consistent always.
The setting of technological datum ball 7 is measured to simplify, and technological datum ball 7 plays the role of coordinate origin.When installation,
As benchmark, the positional precision of cartridge case body to be processed is detected；After processing, successively on the basis of, detect hole machined to be processed and complete
Positional precision afterwards can detect the position dimension in processing hole in real time convenient for measuring.
Since the spatial position in two holes to be processed is different, and the angle in hole also differs, when a hole machined to be processed
