The gear grinding machine is a gear machining machine tool for machining a tooth surface of a cutter by using a grinding wheel as a die. The method is mainly used for eliminating deformation after heat treatment and improving gear precision, and the precision of the gear after grinding can reach 6-3 levels (JB 179-83) or higher. The gear grinding machine includes: machining device, electro-magnet thrust unit and saw bit support. The saw blade bracket is used for fixing a saw blade to be processed, and a first electrode which is contacted with the saw blade to be processed is arranged on the saw blade bracket. The processingequipment is used for treating the processing of processing saw bit, includes: the device comprises a driving device (motor) and a processing grinding wheel, wherein the driving device is used for driving the processing grinding wheel to move along a set direction, and the processing grinding wheel can move along the set direction by controlling the rotation direction of the motor, for example, forward rotation and reverse rotation. The electromagnet pushing device is provided with a second electrode which is in contact with the processing grinding wheel, the core of the electromagnet pushing device is an electromagnet, when the electromagnet is electrified, strong magnetic force can be generated, the magnetic force can push the second electrode to be in contact with the processing grinding wheel, when the electromagnet is powered off, the magnetic force disappears, the electromagnet returns to the initial position, and the second electrode is not in contact with the processing grinding wheel.
The PLC controller 11 is connected to the switching power supply 12 and the voltage module 13, respectively, and is used as a control center of the automatic tool setting control system 10A, and when receiving an automatic tool setting command, for example, when an operator presses an automatic tool setting button, the PLC controller 11 sends a first control command to control the switching power supply 12 to be turned on, so as to power up a processing device, an electromagnet pushing device, and the like; in addition, the PLC controller 11 is further configured to, when receiving the first signal sent by the voltage module 13, automatically lock and save each parameter system after the PLC obtains the signal, and determine whether the tool setting operation is completed, and if yes, control the switching power supply 12 to be turned off so as to end the automatic tool setting operation, and thereafter, start the processing device to process the saw blade to be processed until the saw blade is processed, for example, sharpen the saw blade, and stop processing after sharpening is completed by setting the number of teeth.
In order to improve the tool setting accuracy, the size adjustment corresponding to the tooth form needs to be selected from different directions, that is, the machining grinding wheel is moved in different preset directions by controlling the forward and reverse rotation of the motor. As one embodiment, the PLC controller 11 determines whether the operation for the pair of gears is completed by determining whether the number of times of the received first signal transmitted from the voltage module 13 is equal to a preset threshold. If the signal is equal to the signal, the PLC 11 can receive the signal sent by the voltage module 13, in other words, when the PLC receives the signal sent by the voltage module 13, the PLC indicates that the tool setting operation in the direction is completed.
The first control command may be a level signal, such as a high level or a low level. The low level indicates a voltage having a voltage value lower than a first value, which is a common value in the industry. For example, the first value is typically 0.0V-0.4V for TTL circuits and 0.0-0.1V for CMOS circuits. In the embodiment of the present invention, preferably, the first value is 0V, i.e., the low level is 0V. The high level indicates a voltage having a voltage value higher than a second value, which is a common value in the industry. For example, the second value is typically 2.4V-5.0V for TTL circuits and 4.99-5.0V for CMOS circuits. In the embodiment of the present invention, preferably, the second value is 3.3V, that is, the high level is 3.3V.
The PLC controller 11 may be replaced by other components having corresponding control functions, for example, a central processing unit (Central Processing Unit, CPU), a network processor (Network Processor, NP), etc.; but also digital signal processors (Digital Signal Processing, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), off-the-shelf programmable gate arrays (Field Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

The switching power supply 12 is turned on or off according to the control of the PLC controller 11, and supplies power to the processing device, the electromagnet pushing device, the voltage module 13, and the like when turned on. In this embodiment, it is preferable that the embodiment is as shown in fig. 2. The switching power supply 12 includes a first power supply 121, a second power supply 122, and a third power supply 123.
The first power source 121 is connected to the PLC controller 11, and is also connected to the voltage module 13 and the first electrode, respectively. The first power supply 121 is turned on or off according to the control of the PLC controller 11, and supplies power to the voltage module 13 when an automatic tool setting command is received, for example, when an operator presses an automatic tool setting button, according to the control of the PLC controller 11. When automatic tool setting is completed, i.e., tool setting in each direction is completed, the PLC control controls the turning off of the first power supply 121. Wherein, the first power supply 121 is a direct current power supply of 5V, 12V or 24V.
The second power supply 122 is connected to the PLC controller 11 and also to the electromagnet pushing apparatus. The second power supply 122 is turned on or off according to the control of the PLC controller 11, for example, when an automatic tool setting command is received, for example, when an operator presses an automatic tool setting button, is turned on according to the control of the PLC controller 11, and supplies power to the electromagnet pushing device. When automatic tool setting is completed, i.e., tool setting in each orientation is completed, the PLC control controls the second power supply 122 to be turned off. Optionally, the second power source 122 is a direct current power source of 5V, 12V or 24V.
The third power supply 123 is connected to the PLC controller 11 and also to the processing device. The third power supply 123 is turned on or off according to the control of the PLC controller 11, for example, when an automatic tool setting command is received, for example, when an operator presses an automatic tool setting button, is turned on according to the control of the PLC controller 11, and supplies power to the machining device, thereby driving the machining grinding wheel to move in a preset direction. The third power supply 123 may be a dc power supply or an ac power supply, and is mainly dependent on the type of the motor, for example, when the motor is a dc motor, the third power supply 123 is a dc power supply, and when the motor is an ac motor, the third power supply 123 is an ac power supply.
The voltage module 13 is further configured to be connected to the first electrode and the second electrode, and send the first signal to the PLC controller 11 when the voltage module 13 detects the voltage between the first electrode and the second electrode, where the grinding wheel to be machined contacts the saw blade to be machined.

The first controller 131 is further connected to the relay 132, and is configured to control a state of the relay 132, that is, when the first controller 131 receives the voltage detected by the voltage detecting unit 133, the first controller 131 controls the relay 132 to switch from the first state to the second state, so that the PLC controller 11 receives the first signal sent by the voltage module 13. After a preset period of time, the first controller 131 switches the relay 132 from the second state to the first state again, so as to perform subsequent tool setting operations in different directions. The first state is that the common contact of the relay 132 is connected with a normally closed contact, and the second state is that the common contact of the relay 132 is connected with a normally open contact.
The first relay 132 may be an integrated circuit chip with signal processing capability. The first relay 132 may be a general-purpose processor, including a central processing unit (Central Processing Unit, CPU), a network processor (Network Processor, NP), etc.; but also digital signal processors (Digital Signal Processing, DSP), application specific integrated circuits (Application Specific Integrated Circuit, ASIC), off-the-shelf programmable gate arrays (Field Programmable Gate Array, FPGA) or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components.

The common contact of the relay 132 is connected to the power supply unit 134, the control terminal thereof is connected to the first controller 131, and the normally open contact thereof is connected to the PLC controller 11. When the common contact is connected with the normally-closed contact, the common contact is in a first state, and when the common contact is connected with the normally-open contact, the common contact is in a second state. The relay 132 is in a first state or a second state according to the control of the first controller 131, and in addition, the relay 132 may be controlled to switch from the second state to the first state according to the control of the PLC controller 11, for example, when the PLC controller 11 receives a first signal, to switch from the second state to the first state, so as to perform subsequent tool setting operations in different directions.
