Problems solved by technology

At present, the method of end milling is usually used to meet the verticality requirements of the end face. Due to the different sizes of the cross-section of the components, shrinkage deformation caused by welding, and vibration during milling, it is difficult to control the verticality of the end milling, especially if there is no suitable The milling fixture will greatly increase the difficulty of adjustment during milling and increase the milling positioning time

Abstract

The invention discloses a fixture for end milling of H-shaped and box-type components and cross columns. The fixture is characterized by comprising a fixture frame, a steel column and a milling fixture component. The steel column is rested on the fixture frame. Supports are welded on two sides of the steel column on the fixture frame. Holding deviation preventers are disposed between one side of the steel column and the corresponding support. Leveling jacks are used to support the bottom of the steel column and fixed through clamps. The milling fixture component is disposed on one side of the steel column and comprises a scribing pin and a miller disc. Each holding deviation preventer comprises a hemisphere, a holding jack and an anti-vibration pad. The holding jacks are fixed through brackets. Each anti-vibration pad is provided with a conical groove which matches with one hemisphere. The fixture has the advantages that the steel column is positioned fast, the ends of the components are convenient to level, deviation of the steel column is prevented during milling and dents on the surfaces of the components caused during holding are avoided.

Description

technical field [0001] The invention relates to a fixing fixture, in particular to an H-shaped, box-shaped component and a cross column end milling fixing fixture. Background technique [0002] H-shaped and box-shaped steel columns are widely used in steel structure buildings, but the verticality of the upper and lower ends of each steel column directly affects the installation accuracy and quality of the building. At present, the method of end milling is usually used to meet the verticality requirements of the end face. Due to the different sizes of the cross-section of the components, shrinkage deformation caused by welding, and vibration during milling, it is difficult to control the verticality of the end milling, especially if there is no suitable The milling fixture will greatly increase the difficulty of adjustment during milling and increase the milling positioning time. Therefore, the clamping method of milling must be improved to ensure the quality and efficiency ...
