Cam type automatic rotary lifting tool changing mechanism

Abstract

The invention discloses a cam type automatic rotary lifting tool changing mechanism which comprises a combined type tank body, a control box and a motor. The control box is located on the right side of the combined type tank body. The motor is installed on the combined type tank body. The surface of the combined type tank body is provided with a driving lever bearing pedestal, two eccentric bearing pedestals and a decorative cover. The left side of a motor base is provided with a worm bearing pedestal. The right side of the motor base is provided with a force output bearing pedestal. A lifting output shaft, a chain wheel frame, a chain, an adjusting chain wheel, a force output rotary tower, a driving lever, a force input shaft, an arc face cam, a driving chain wheel, a worm shaft, a worm wheel and a driving lever shaft are arranged in the combined type tank body. A ball bearing, an induction cam shaft, an induction cam, a driven chain wheel, a pointer, an induction support and a proximity switch are arranged in the control box. The lifting tool changing ability of the mechanism is improved, and the mechanism has the good service life and lasting stability and is good in using effect when used for automatically changing heavy handle tools of large tool magazines.

Description

technical field [0001] The invention relates to a tool changing mechanism, in particular to a cam type automatic rotating lifting tool changing mechanism. Background technique [0002] At present, the tool change mechanism of the machine tool magazine mostly uses a cam-type automatic rotary lifting tool change mechanism published in the Chinese invention patent 201520549546.2 on January 20, 2016, including a motor, a combined box and an integrated casting with the box. The control box and the motor are installed in front of the combined box through the motor connecting flange. The upper surface of the combined box is respectively provided with a lever bearing seat, an eccentric bearing seat and a decorative cover from left to right. The combined box on the right side of the motor The output bearing seat is arranged on the box, and the rear of the combined box body corresponding to the output bearing seat is provided with a guide sleeve seat; the inside of the combined box bo...

Problems solved by technology

The present invention is used in the cam-type automatic rotating lifting tool changing mechanism of the CNC machine tool magazine, which improves the lasting stability of the structure, and also has the same stability in the relative speed-up state, and realizes the improvement of efficiency at the same time; this structure is used When it is used for automatic tool change of medium and light tool holder tools, it has better lifting and tool changing ability and stability, but when it is used for tool change in the tool magazine of heavy tool holder tools, the service life of the mechanism will be greatly reduced, or even directly Cause damage and cannot meet production needs, which brings inconvenience to people's use
