Description
Technical Field
The utility model relates to a machine tool equipment field, concretely relates to main shaft collision avoidance system.
Background
The numerical control machine tool is an automatic machine tool with a program control system.
When the machine tool spindle is in a working state, drift can be generated due to mechanical vibration and the like, so that the working position of the spindle is easily inaccurate, and the spindle can generate the displacement on an X axis, a Y axis and a Z axis. The moved main shaft collides with the workpiece, and the problem that the machined shape of the workpiece is inaccurate is easily caused.
Therefore, it is an inevitable focus of the skilled person to design an anti-collision system capable of suppressing the drift of the spindle of the machine tool.
Disclosure of Invention
In order to overcome not enough among the prior art, the utility model discloses a main shaft collision avoidance system, it has the displacement to main shaft X axle, Y axle and Z axle and detects and the benefit of feedback.
In order to achieve the purpose, the utility model discloses a main shaft collision avoidance system, including lathe main shaft, three-axis motor, collision avoidance system still includes shock transducer, aviation plug, electric cabinet, CNC controller, and shock transducer installs on the lathe main shaft, and shock transducer passes through aviation plug and electric cabinet electric connection, electric cabinet and CNC controller electric connection, CNC controller and lathe main shaft and three-axis motor electric connection.
Further, the CNC controller is electrically connected with the three-axis motor through a JA40 line.
Further, the vibration sensor is installed on the top of the machine tool spindle through a bolt.
Further, the installation position of the vibration sensor is not collinear with the axis of the machine tool spindle.
Furthermore, the three-axis motor comprises an X-axis motor, a Y-axis motor and a Z-axis motor, and the X-axis motor, the Y-axis motor and the Z-axis motor are all connected with the machine tool spindle.
Has the advantages that: the displacement vibration of the machine tool spindle on an X axis, a Y axis or a Z axis is recorded through the vibration sensor, the vibration sensor sends a displacement signal generated by the vibration to the CNC controller, and the CNC controller makes the displacement opposite to the vibration displacement of the machine tool spindle on the three-axis motor, so that the purpose of restraining the vibration of the machine tool spindle is achieved.

Reference numerals: 1. a machine tool spindle; 2. a shock sensor; 3. an aviation plug; 4. an electric cabinet; 5. a CNC controller; 6. an X-axis motor; 7. a Y-axis motor; 8. a Z-axis motor.
Detailed Description
The technical solution of the present invention will be more clearly and completely explained by the description of the preferred embodiments of the present invention with reference to the accompanying drawings.
As shown in fig. 1, the utility model discloses preferred embodiment's main shaft collision avoidance system, including lathe main shaft 1, three-axis motor, shock transducer 2, aviation plug 3, electric cabinet 4, CNC controller 5.
The vibration sensor 2 is arranged at the top of the machine tool spindle 1, and the installation position of the vibration sensor 2 is not collinear with the axis of the machine tool spindle 1. Preferably, the vibration sensor 2 is fixed on the top of the machine tool spindle 1 through bolts.
The vibration sensor 2 is electrically connected with the aviation plug 3 through a data line, the aviation plug 3 is electrically connected with the electric cabinet 4, and the electric cabinet 4 is connected with the input end of the CNC controller 5. The vibration sensor 2 moves along with the movement of the machine tool spindle 1, the vibration sensor 2 feeds detected offset in the X axis, the Y axis and the Z axis back to the vibration sensor 2, and the vibration sensor 2 transmits offset data of the X axis, the Y axis and the Z axis to the CNC controller 5.
The CNC controller 5 is simultaneously because triaxial motor and lathe main shaft 1 are connected, and is specific, and the output of CNC controller 5 and triaxial motor electric connection are used for receiving the signal of vibrations sensor 2 and make corresponding action. The three-axis motor is mainly an X-axis motor 6, a Y-axis motor 7 and a Z-axis motor 8, and the CNC controller 5 is electrically connected with the three-axis motor through a JA40 line. The output end of the CNC controller 5 is connected with the machine tool spindle 1 and used for controlling the machine tool spindle 1 to rotate.
The purpose of this embodiment is to record the displacement vibration of the machine tool spindle 1 on the X axis, the Y axis or the Z axis through the vibration sensor 2, the vibration sensor 2 sends the displacement signal generated by the vibration to the CNC controller 5, and then the CNC controller 5 makes the displacement opposite to the vibration displacement of the machine tool spindle 1 to the three-axis motor, so as to achieve the purpose of suppressing the vibration of the machine tool spindle 1.
The above detailed description merely describes the preferred embodiments of the present invention and does not limit the scope of the present invention. Without departing from the design concept and spirit scope of the present invention, the ordinary skilled in the art should belong to the protection scope of the present invention according to the present invention provides the text description and drawings to the various modifications, replacements and improvements made by the technical solution of the present invention. The scope of protection of the present invention is determined by the claims.
