Abstract
The utility model relates to a fixture tool for machining an upper support of a tower crane, and belongs to the technical field of tower cranes. The positioning pin shaft is used for positioning the machining positioning tool and the upper support rotary support mounting holes, and 4 groups of positioning pin shaft mounting holes are formed. The beneficial effects of the utility model are as follows: clamping efficiency is high: because only four pin shafts are required to be assembled and disassembled in the secondary positioning process, the efficiency is improved by more than 70% compared with that of assembling and disassembling about 8 clamping plates; positioning efficiency is high: the positioning tool is directly fixed on a working platform of the machining center, so that the positioning tool is not dismounted in the later period, and the positioning precision is high; positioning reliability is high: because the datum is fixed, the machining datum is uniform every time, the reliability is higher, and the later-period searching problem is simpler.
Description
Technical Field
The utility model relates to a fixture tool for machining an upper support of a tower crane, and belongs to the technical field of tower cranes.
Background
In the existing machining process of the upper support, the first scheme is to machine the rotary support mounting surface first, and then to turn over the workpiece to machine the mounting hole and the mounting surface of the rotary mechanism (rotary speed reducer). The second process is to process the mounting hole and the mounting surface of a rotary mechanism (a rotary speed reducer) by a milling machine, then to process the rotary support mounting surface after turning over the workpiece, and finally to process the rotary support mounting hole by using a drilling jig for positioning.
The first scheme can finish machining by one device in the drilling and milling machining center, but needs secondary clamping and secondary positioning, and needs manual reference point searching again, so that human errors are easy to generate, the errors are uncontrollable, the manual reference point searching has high requirement on experience, and the time consumption is long.
The second scheme needs to finish processing in milling machine, drilling machine multiple equipment, also needs secondary clamping, location, and the centre-to-centre spacing of each product, gyration support size are inconsistent, need multiple jig, and manufacturing cost is higher, because the drilling machine adopts artifical tool setting, compares in the digit control machine tool to personnel's experience requirement high.
Disclosure of utility model
In order to overcome the defects of the prior art, the utility model provides the fixture tool for the support machine on the tower crane, which is used for machining on a numerical control machine tool, simplifying the steps of secondary clamping and positioning, improving the efficiency and the precision and reducing the positioning difficulty.
The utility model is realized by the following technical scheme: a tower machine upper bracket machine adds anchor clamps frock, its characterized in that: the positioning pin shaft is used for positioning the machining positioning tool and the upper support rotary support mounting holes, and 4 groups of positioning pin shaft mounting holes are formed.

The machining positioning tool and the machining center are fixed on a working plane.
The upper surface and the lower surface of the machining positioning tool are machined surfaces.
The beneficial effects of the utility model are as follows: (1) clamping efficiency is high: because only four pin shafts are required to be assembled and disassembled in the secondary positioning process, the efficiency is improved by more than 70% compared with that of assembling and disassembling about 8 clamping plates;
(2) Positioning efficiency is high: the positioning tool is directly fixed on a working platform of the machining center, so that the positioning tool is not dismounted in the later period, and the positioning precision is high;
