It is required that less than 0.01mm.In order to guarantee verticality requirement, conventional brace is first is that installation is inconvenient, second is that all needing after mounting cumbersomely
It carries out playing table calibration, time-consuming and laborious, the quasi- knot overlong time of Cutter Body Processing with Machining Center.
Summary of the invention
For above-mentioned deficiency present in the prior art, the technical problem to be solved by the present invention is to toolings when cam ring processing
Dismounting is inconvenient, and verticality checks time-consuming and laborious.
In order to solve the above technical problem, the present invention provides a kind of cam rings to process auxiliary mould, including platen, collateral
Frame, corner cylinder, pressing plate, airtight inspecting hole, locating piece,
The cam ring is mounted in the locating piece, and the locating piece is mounted on the platen, the platen bottom
Two sides are equipped with the side stand, and the side stand is locked in machine table in machining center by bolt, the cam ring bottom
Locating piece on be provided with the airtight inspecting hole, the airtight inspecting hole leads to airtight inspection by the gas circuit inside the platen
Cha Yi；
The locating piece is respectively arranged with the corner cylinder in two sides up and down, and the corner cylinder is connected with pressing plate, described
Corner cylinder is clamped and is unclamped with clamping oil circuit control by unclamping oil circuit, and the release oil circuit, clamping oil circuit penetrate through between each other.
Further, the release oil circuit, clamping oil circuit are located in the platen, and the release oil circuit clamps oil circuit position
On the outside of platen, including two parallel technique through-holes and a vertical technique through-hole, and only have one outlet respectively, remaining
It is blocked by tapered plug, it is described to unclamp oil circuit, clamp the piston that oil circuit leads to each corner cylinder.
Further, it there are two the locating pieces, is mounted on platen side by side, two cam rings can be processed every time, it is described
There are four corner cylinders, respectively with concatenated release oil circuit, clamp oil circuit connection.
Further, the locating piece includes two circular steps, section be it is inverted T shaped, on the inside of the step at top with it is described
Be provided with the airtight inspecting hole on the bottom surface of cam ring contact, the airtight inspecting hole on each locating piece there are three, connect
The bottom surface of touching forms annular distance and avoids.
Further, for the ease of the cam ring of processing different size, the locating piece is replaceable, the ring-shaped step of bottom
There are two semicircular indentations for outer ring setting, are positioned by positioning pin；The locating piece is mounted on square plate shape by bolt
