Technical Field
The utility model relates to a field, in particular to be applied to Y type cavity encoder of electricity main shaft and connect.
Background
The electric spindle is a new technology for integrating a machine tool spindle and a spindle motor into a whole in the field of numerical control machines, and because the electric spindle integrates the motor into a spindle unit and has high rotating speed, a large amount of heat can be generated during operation to cause spindle temperature rise, so that the thermal state characteristic and the dynamic characteristic of the electric spindle are poor, and the normal work of the electric spindle is influenced. Therefore, some measure must be taken to detect the temperature rise of the electric spindle and to give an alarm in time.
A hollow encoder is a device that converts an angular displacement into an electrical signal. The encoder is generally composed of a reading head and a magnetic ring. The magnetic ring is provided with small magnetic poles at equal intervals, and after the magnetic poles are magnetized, a periodically distributed space leakage magnetic field is generated during rotation. The reading head converts the changing magnetic field signal into the resistance value change through the magnetic resistance effect, and the resistance value change is converted into a digital signal which can be identified by a calculator through subsequent signal processing, so that the coding function of the position sensor is realized.
A conventional hollow encoder includes a reading head, an output signal line electrically connected to a circuit board in the reading head, and an output signal terminal electrically connected to a terminal of the output signal line. When the temperature sensing line of the electric spindle is used, the temperature sensing line on the electric spindle is electrically connected with the reading head by the temperature sensing connecting line, and the electric signal is transmitted by the temperature sensing connecting line. The connection point of the temperature-sensing connecting wire and the reading head is positioned in the reading head, and the reading head needs to be disassembled when the temperature-sensing connecting wire is led out. The reading head belongs to tiny accurate part, causes the reading head trouble easily when non-professional dismouting reading head, causes the sharp increase of use cost. The disassembly and assembly of the reading head excessively depends on operators, the use is difficult, and the efficiency is influenced.
