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.

Example Embodiment

[0018] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:
[0019] by figure 2 It can be seen that the present invention is realized through the following steps:
[0020] The programmable controller issues instructions to control the forward and reverse rotation of the tool magazine to the electronic brake;
[0021] Start the tool magazine device through the electronic brake and operate according to the instructions of the programmable controller;
[0022] The position detection sensor sends back detection signals to the programmable controller;
[0023] Through the calculation and processing of the programmable controller, when the returned detection signal meets the instruction requirements, the programmable controller instantly sends an instruction to the electronic brake;
[0024] The electronic brake immediately stops the operation of the tool magazine device upon receiving the instruction, and at the same time, generates an electromotive force in one direction to complete the braking action, so that the tool magazine device accurately and reliably runs and stops in accordance with the instructions of the programmable controller.
[0025] Compared with the prior art, the difference between the present invention and the prior art is that the mechanical brake is changed to an electronic brake; in addition, the interconnection of various components has also changed. In the prior art, there is a direct relationship between the programmable controller and the tool magazine device. The present invention changes the direct relationship between the programming controller and the tool magazine device into an indirect control relationship.
[0026] The invention adopts the electronic brake of the prior art; the electronic brake has the functions of instantaneous stop, forward and reverse operation, electronic brake control and protection detection of the motor to be treated. In the present invention, instantaneous stop, forward and reverse running, and electronic brake control functions are used. The electronic brake can be purchased separately and conveniently in China, and the electronic brake of the present invention is purchased from Shanghai Yiyou Transmission Equipment Co., Ltd.
[0027] The invention adjusts the brake of the tool magazine device of the CNC drilling and tapping machine from a mechanical brake to an electronic brake in the traditional circuit control, which overcomes the problem of the tool magazine device stopping early or delaying in the traditional control. The problem of phenomena. The tool magazine device can execute exactly and reliably according to the expected action of the programmable controller of the control center.
[0028] The invention transforms the tool magazine control of the numerical control drilling and tapping machine from mechanical braking to electronic braking, solves the problem of inaccurate and unstable control of the domestic numerical control drilling and tapping machine tool magazine, and reduces the failure rate; The domestic procurement of all parts is reduced, and the manufacturing cost is reduced; the structure is simple, clear and easy to maintain.
