Horizontal harmonic reduction rotating working table

Abstract

The invention relates to a horizontal harmonic reduction rotating table. The horizontal harmonic reduction rotating working table comprises a horizontal mounting seat, a rotating assembly and a clampassembly. The horizontal mounting seat comprises a first cavity, a second cavity and a connecting portion connecting the first cavity with the second cavity. A wire groove being communicated with thefirst cavity and the second cavity is formed in the connecting portion. The rotating assembly comprises a servo motor, a harmonic reducer and a working chuck. The servo motor is mounted in the first cavity. The input end of the harmonic reducer is in transmission connection with the output end of the servo motor. The output end of the harmonic reducer is in transmission connection with the workingchuck. The clamp assembly is fixedly mounted on the working chuck. A clamp pressing screw is mounted on the clamp assembly in a matched manner. The clamp pressing screw can fix a product on the clampassembly. The horizontal harmonic reduction rotating table has the beneficial effects that the harmonic reducer using the zero back clearance is connected with the servo motor, so that the defect that the angle is inaccurate due to the gear back clearance generated when a common gear matched with a speed reducer rotates forwards or reversely is eliminated.

Description

technical field [0001] The invention relates to the technical field of mechanical turntables, in particular to a horizontal harmonic deceleration rotary worktable. Background technique [0002] At present, there are many types of rotary mechanisms commonly used in the market, such as: servo motor acceleration and deceleration machine to drive the workbench to rotate, DD motor direct drive, servo motor to drive the dividing disc to perform the rotating work of the worktable, etc., among which the servo motor drives the dividing disc to work Table rotary work is the most widely used in the existing market. When performing tool calibration during processing, the tool calibration instruments in the market are basically installed in the tool magazine or on the machine body. The existing rotary table has the following defects: [0003] First, engraving, drilling and milling, multi-angle processing, turning and milling are used in small and medium-sized precision machining, and t...

AI Technical Summary

Problems solved by technology

During forward and reverse rotation, when the gear of the reducer is forward and reverse, there must be backlash, which will lead to deviation of indexing accuracy and decrease in accuracy.

[0004] Second, when the workbench operates at low speed, a large output torque is usually required to install a reducer with a large speed ratio for output, but the reducer with a large ratio is relatively large in size. Due to the limitation of the internal space of the machine, Therefore, it is necessary to increase the size of the equipment to install the rotary table

[0005] Third, when parts need to be processed at multiple angles during the processing process, the vertical installation cannot realize the angular swing of the rotary table

[0006] Fourth, the installation of the tool setting instrument is basically installed in the tool magazine, so when the tool is damaged during processing and needs to be replaced, the machine must be stopped and returned to the original place, and then the tool calibration is performed in the tool magazine, so the processing time is greatly increased. Improve processing time

When the tool setting instrument needs to be maintained and repaired, the tool magazine must be opened for maintenance every time it is maintained or needs to be replaced, which increases the difficulty and working time

[0007] Fifth, the existing tool setting instrument is basically installed on the tool 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, so in The movement of the tool magazine is accompanied by vibration, which will lead to a decrease in the repeated positioning accuracy of the tool setting instrument, and the aging of the machine will cause a more serious decline in tool setting accuracy over time.

However, in the existing installation structure, the harmonic reducer needs to bear axial and radial loads at the same time, which leads to a decrease in the stability of the installed rotary table during rotation and is prone to vibration
