Cantilever-type five-shaft rocker arm rotating device with harmonic speed reducer

Abstract

The invention relates to a cantilever-type five-shaft rocker arm rotating device with a harmonic speed reducer. The cantilever-type five-shaft rocker arm rotating device comprises a horizontal mounting seat, a rotating shaft assembly, a swing arm shaft assembly, a working chuck, a product clamp assembly and clamp pressing screws, wherein the horizontal mounting seat comprises a first cavity, a second cavity and a connecting part; a wiring hole is formed in the connecting part; the rotating shaft assembly is arranged in the first cavity; the swing arm shaft assembly is connected with the secondcavity; the axis of the rotating shaft assembly is perpendicular to the axis of the swing arm shaft assembly; the working chuck is in transmission connection with an output end of the rotating shaftassembly; the product clamp assembly for carrying products is mounted on the working chuck; the clamp pressing screws are arranged on the product clamp assembly; and a tool setting instrument is arranged on the side wall of the horizontal mounting seat. The cantilever-type five-shaft rocker arm rotating device has the advantages that stable operation can be kept while a tail seat supporting structure is removed, and the limitation of installation space is eliminated while large torque is provided at low rotating speed, therefore, the difficulty of tool setting is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical turntables, in particular to a cantilevered five-axis rocker arm turning device with a harmonic reducer. Background technique [0002] At present, with the improvement of industrial requirements in the market, the corresponding level of automation is gradually improving. More and more four-axis and five-axis equipment are used in factories. Among them, in the processing of the five-axis rocker-arm turntable, the angle of the inclined axis needs to be adjusted manually, and then the positioning is fixed; in one clamping, only one-angle drilling, milling, turning, etc. of the part can be processed, which is very limited. [0003] When the processing parts need to increase multiple angles or surface processing, the vertical installation cannot realize the angular swing of the rotary table, so it needs to be changed to a five-axis rotary table, so it takes a lot of time to disassemble and replace ...

AI Technical Summary

Problems solved by technology

[0004] The five-axis installation or the existing five-axis rocker arm installation is equipped with a tailstock support mechanism. The five-axis rocker arm mechanism with a tailstock needs to increase the installation space due to the existence of the tailstock, and the corresponding machine tool The reserved installation size increases, which leads to an increase in the cost of the machine, and there is a risk of idleness during use

The existing tool setting instrument is basically installed on the inverted magazine, but when the tool setting instrument is working, the tool magazine must be extended, and the tool magazine will be suspended, and the power of the tool magazine is basically driven by the cylinder. The movement is accompanied by vibration, which will lead to a decrease in the repeated positioning accuracy of the tool setting instrument, and as time goes on, the aging of the machine will cause a more serious decline in the accuracy of tool setting
