Tool magazine speed reducer

Abstract

The invention relates to the technical field of machine tool equipment, in particular to a tool magazine speed reducer which comprises an input rod, an input rod quick-release connecting shaft device, an output wheel, an automatic dismounting device and a box shell, the output wheel is rotatably fixed to the box shell, a plurality of roller assemblies are rotatably connected to the circumference of the output wheel, the roller assemblies are arranged at equal angles, and the automatic dismounting device is arranged on the box shell. The problem that the worm wheel and the worm are damaged due to friction and are not easy to replace is solved, sliding friction is changed into rolling friction through the roller assemblies, and the problem that the precision is reduced due to abrasion between the worm wheel and the worm is greatly solved.

Description

technical field [0001] The invention relates to the technical field of machine tool equipment, in particular to a tool magazine reducer. Background technique [0002] The transmission mechanism of the disc tool magazine of the machining center generally uses more than 20 tools. These tools are installed in the tool pocket of the chain. When many different tools are used, the tool magazine needs to be rotated and positioned accurately and quickly. Servo drive. The existing servo transmission structure includes a worm gear reducer, a servo motor, a mechanism body, a driving gear, a bearing, a nut, a rotating shaft, a spacer, a driven gear, an upper mounting frame and a lower mounting frame. Among them, the worm gear reducer is fixed on the mechanism body through the upper bracket and the lower bracket, the servo motor is installed on the turbine worm reducer, and the rotating shaft is fixed on the mechanism body. When it needs to be rotated, the servo motor rotates, and the ...

AI Technical Summary

Problems solved by technology

[0003] The structural principle of the original worm gear reducer leads to the inevitable wear between the turbine and the worm due to friction. The wear between the turbine teeth and the worm teeth will cause the turbine teeth to collide with the worm teeth, causing abnormal noise. It will lead to problems such as decreased precision and lower product yield rate. Due to the high structural integration of the machining center, the replacement of the worm gear often requires the removal of the entire reducer before the turbine and worm can be maintained, which is extremely difficult.
