Rotary clamping type planter tool magazine and automatic tool changing method

Abstract

The invention discloses a rotary clamping type planter tool magazine. The rotary clamping type planter tool magazine comprises a tool rest base, wherein a tool rest foundation support is arranged on the tool rest base, supporting rods are arranged on the tool rest foundation support, the bottoms of the supporting rods penetrate through the tool rest foundation support and are elastically connectedwith the tool rest knife rest, a disc tool rest is mounted at the tops of the supporting rods, a driving shaft and driven shafts are arranged on the tool rest foundation support, and a transmission gear is arranged between the driving shaft and the driven shafts; a second rotating mechanism used for driving the driving shaft to rotate is arranged on the tool rest foundation support, nut holes corresponding to the driven shafts in positions are formed in the disc tool rest, a locking nut is fixed in each nut hole, a conical groove is formed in the top of each driven shaft, an elastic chuck isarranged in each conical groove, and the top of each driven shaft is in threaded fit with the corresponding locking nut. The tightness of the elastic chucks is adjusted and controlled through rotatingfit of the driving shaft and the driven shafts, the automatic tool changing requirement of a mechanical arm of a planter is met, the clamping stability is high, the processing efficiency is effectively improved, and the production cost is reduced. The invention further provides an automatic tool changing method.

Description

technical field [0001] The invention relates to a rotary clamping type planter tool magazine and an automatic tool changing method, belonging to the field of dental technology. Background technique [0002] Dental implant is a method of edentulous restoration based on the lower structure implanted in bone tissue to support and retain the upper tooth restoration. It includes two parts: the lower supporting implant and the upper tooth restoration. Implants are made of artificial materials (such as metal, ceramics, etc.), surgically implanted into tissues (usually the upper and lower jaws) and obtain firm retention support from bone tissue, and connect and support dental restorations through special devices and methods . Dental implants can obtain functions and structures similar to natural teeth, and have a beautiful appearance and good restoration effect. It has become the preferred restoration method for more and more patients with missing teeth. [0003] With the rapid de...

Problems solved by technology

[0004] The existing planter tool magazine system is still in the development stage. On the one hand, the clamping of the tool by the existing tool seat is not stable, so that the planter mechanical arm cannot complete the tool change process quickly and accurately. On the other hand, due to The tool mounting hole on the mechanical arm of the planter has a certain friction force even after it is loosened, so that the tool cannot be disengaged independently, and a certain pulling force is required to assist the tool to disengage
