H type, box-type member and cross column end mill stationary fixture
The present invention relates to stationary fixture, particularly relate to a kind of H type, box-type member and cross column end mill stationary fixture.
In steel building, H type, steel box column are widely used, but often the perpendicularity of the joint upper and lower both ends of the surface of steel column directly affects installation accuracy and the quality of building.The method of face milling is the most generally used to reach end face squareness requirement, owing to sectional dimension of members is not of uniform size, and should weld and cause contraction distortion, and the factor such as vibrations during milling makes the perpendicularity of end mill be difficult to control, particular without suitable milling fixture, the difficulty adjusted when this will be greatly improved milling, adds milling positioning time.So the clamping method of milling must be improved, it is ensured that the quality of milling and efficiency.
Therefore, the technology of a kind of improvement it is badly in need of to solve this problem in the presence of prior art.
Summary of the invention
It is an object of the invention to provide a kind of H type, box-type member and cross column end mill stationary fixture.
The technical solution used in the present invention is:
H type, box-type member and cross column end mill stationary fixture, including moulding bed, steel column and milling fixture assembly, described steel column is located on moulding bed, on described moulding bed, steel column both sides welding equipment respectively has bracing frame, described steel column is wherein provided with between side and bracing frame and holds out against anti-deflection device, is supported by leveling jack bottom described steel column, and described leveling jack is fixed by Karma, steel column side is located at by described milling fixture assembly, and described milling fixture assembly includes scriber and facing cutter.
The described anti-deflection device that holds out against includes hemisphere, holds out against jack and against shock cushion block, described in hold out against jack and fixed by support, described against shock cushion block is provided with conical grooves, cooperates between described conical grooves and hemisphere.
Described hemisphere and hold out against and be bolted clamping between jack.
Described cradle top and holding out against between jack contact surface as arc plate.
Described scriber passes through magnet adsorption on facing cutter.
The invention have the advantage that steel column quickly positions, facilitate component ends regulation level, anti-offset during steel column milling, avoid component to cause component surface that indenture occurs when holding out against simultaneously.

Detailed description of the invention
nullAs shown in figures 1 to 6，The H type of the present invention、Box-type member and cross column end mill stationary fixture，Including moulding bed 1、Steel column 2 and milling fixture assembly，Described steel column 2 is located on moulding bed 1，On described moulding bed 1, steel column 2 both sides welding equipment respectively has bracing frame 3，It is provided with between described steel column 2 wherein side and bracing frame 3 and holds out against anti-deflection device，The described anti-deflection device that holds out against includes hemisphere 4、Hold out against jack 5 and against shock cushion block 6，Described hemisphere 4 and holding out against is fixed to clamp by bolt 7 between jack 5，The described jack 5 that holds out against is fixed by support 8，Described support 8 top and holding out against between jack 5 contact surface as arc plate 9，Described against shock cushion block 6 is provided with conical grooves 10，Cooperate between described conical grooves 10 and hemisphere 4，Supported by leveling jack 11 bottom described steel column 2，Described leveling jack 11 is fixed by Karma 12，Steel column 2 side is located at by described milling fixture assembly，Described milling fixture assembly includes scriber 13 and facing cutter 14，Described scriber 13 is adsorbed on facing cutter 14 by Magnet 15.
Bracing frame 3 is utilized quickly to position, being simultaneously located at the leveling jack 11 below steel column 2 can be with easy adjustment steel column 2 level, ensure that milling end is vertical with facing cutter 14, the form of top hemisphere 4 and conical grooves 10 attachment structure in anti-deflection device that holds out against of side has been effectively ensured laminating degree and the transmission of pressure holding out against anti-deflection device and steel column 2, prevent steel column 2 from offseting, effectively reduce the unfavorable factor that the vibrations of milling generation are brought, it is always ensured that steel column 2 keeps position originally, the quality of end mill is effectively ensured, avoid steel column 2 to cause component surface that indenture occurs when holding out against simultaneously.
First steel column 2 is hung in moulding bed 1, one side is close to bracing frame 3, utilizes the leveling jack 11 adjustment end level of end；After install and hold out against anti-deflection device, utilize and hold out against jack 5 steel column 2 is held out against；Finally utilize the scriber 13 on facing cutter 14 along the quick feed of milling line of steel column 2 end labelling in advance, check every limit institute's labelling milling line position in advance the most correct, i.e. check the perpendicularity of steel column end；I.e. can start milling machine after all and carry out milling.
