Control method of numerical-control drilling and tapping machine tool magazine

Abstract

The invention relates to a control method of a numerical-control drilling and tapping machine tool magazine, which is realized by the following steps: a programmable controller transmits a command for controlling forward or reverse rotation of the tool magazine to an electronic brake; the electronic brake starts a tool magazine device to operate according to the command of the programmable controller; a position detection transducer transmits a detection signal back to the programmable controller; by the calculation and processing of the programmable controller, when the detection signal transmitted back satisfies the command requirement, the programmable controller instantly transmits a command to the electronic brake; and while receiving the command, the electronic brake instantly stops the operation of the tool magazine device and simultaneously generates a direction electromotive force to complete the braking movement, so that the tool magazine device can precisely and reliably operate and stop according to the command of the programmable controller. The invention enhances the precision and stability of control on the tool magazine of the numerical-control drilling and tapping machine, controls the production cost, reduces the failure rate and facilitates maintenance and service.

Description

technical field [0001] The invention relates to a numerical control drilling and tapping machine, in particular to a control method for the tool magazine of the numerical control drilling and tapping machine. Background technique [0002] CNC drilling and tapping machines are widely used in the field of machinery manufacturing and processing, especially in the processing of parts in the fields of electronics, molds, and aerospace technology. However, the accurate control of the tool magazine of the CNC drilling and tapping machine is the difficulty and core in the manufacture of this product. The tool magazine is the basis of the work of the CNC drilling and tapping machine. Only when the movement of the tool magazine is accurate can the continuous automatic processing of multiple processes in one clamping of the drilling and tapping machine be realized. [0003] In recent years, many domestic companies are producing CNC drilling and tapping machines, but the core technolog...

Problems solved by technology

[0006] In the above method, because the mechanical brake is braked by the friction force of the clutch, the friction force of the mechanical brake is constant; the tool magazine device is a warehouse for storing knives, and the number of knives installed directly affects the braking time. The size of the friction force, so the tool magazine device is prone to early stop or delayed stop

Therefore, there are disadvantages of unstable tool change, poor reliability and high failure rate
