The invention discloses a machining process method for a rotary upper bearing frame of a tower crane. The rotary upper bearing frame of the tower crane comprises a machine base, a positioning base is fixedly installed at the top of the machine base, a machined part is fixedly installed at the top of the positioning base, and a workbench is fixedly installed at the top end in the machine base; a driving assembly is fixedly installed at the bottom of the workbench, an up-down sliding table is fixedly installed on the one side of the top of the machine base, and an extension arm is movably installed on the one side of the up-down sliding table. According to the machining process method for the rotary upper bearing frame of the tower crane, the workbench is fixedly installed at the top end in the machine base, the driving assembly is fixedly installed at the bottom of the workbench, a driving motor is started, a shaft sleeve and a large gear are installed in a meshed mode, the driving motor drives the large gear, then the large gear and a small gear are installed in a meshed mode, the large gear and the small gear rotate, and platform clamping blocks are clamped; the platform clamping blocks are matched with the clamping force of bolts and used for clamping a rotary bearing frame, machining quality of workpieces is guaranteed, production efficiency is improved, and precision of the machined parts is improved.
Description
technical field [0001] The invention relates to the technical field of processing a slewing support frame, in particular to a processing method for a slewing upper support frame of a tower crane. Background technique [0002] The slewing bearing is a new type of mechanical component. It consists of inner and outer rings, rolling elements, etc. The slewing bearing is a large bearing that can bear comprehensive loads. It can bear large axial and radial loads and overturning moments at the same time. The support frame is also an important structural part of the tower crane, and during the use of the tower crane slewing upper support frame, there are many problems or defects in the existing tower crane slewing upper support frame: [0003] In the actual use of the traditional tower crane slewing upper support frame, the multiple clamping efficiency is low, the labor intensity is high, and the processing quality is difficult to guarantee. Moreover, the production output of the to...
