The workpiece damage repairing device can adjust the environmental temperature of the workpiece during damage repairing by using the material melting point of the workpiece, and avoids the mechanical property damage of the workpiece caused by overhigh environmental temperature.
The damage degree of the workpiece can be at least one of the number of dislocations accumulated in the crystal grains inside the material of the workpiece and the damage ratio, and if the damage degree is expressed by the number of dislocations, the higher the number of dislocations, the greater the damage degree of the workpiece; if the damage degree is expressed by the damage ratio, the larger the damage ratio is, the larger the damage degree of the workpiece is; if the damage degree is represented by the number of dislocations and the damage ratio, the higher the number of dislocations and the larger the damage ratio, the larger the damage degree of the workpiece.

The workpiece damage repairing device can also output a repairing completion prompt for prompting relevant maintenance personnel to recover the workpiece, and the workpiece is inspected and installed back to the original position to continue working. The preset time may be an initial setting in the workpiece damage repair device, or may be set and stored in the workpiece damage repair device by a related maintenance worker of the workpiece, or may be calculated from historical repair time stored in the workpiece damage repair device, for example, the preset time may be an average value of the historical repair time.

Referring to fig. 3, a schematic flow chart of a method for repairing a damaged workpiece is provided according to an embodiment of the present disclosure. As shown in fig. 3, the method of the embodiment of the present application may include the following steps S201 to S208.
S201, obtaining damage parameters of the workpiece with fatigue damage, and obtaining property parameters and damage degree in the damage parameters.
Specifically, the related maintenance personnel of the workpiece can disassemble and store the workpiece needing to be repaired or inspected so that the workpiece damage repairing device can select the workpiece with fatigue damage to repair the damage, or the related personnel can directly place the workpiece with fatigue damage on the vibrating device, so that the workpiece damage repairing device can conveniently and freely vibrate the workpiece by adopting the vibrating device. The workpiece damage repairing device can acquire damage parameters of a workpiece with fatigue damage, the damage parameters can include property parameters and damage degree of the workpiece, the property parameters represent physical properties of the workpiece and the like, the property parameters can include a material melting point of the workpiece, the damage degree can be at least one of the number of dislocations accumulated in material internal crystal grains of the workpiece and the damage ratio, and if the damage degree is expressed by the number of dislocations, the higher the number of dislocations, the larger the damage degree of the workpiece; if the damage degree is expressed by the damage ratio, the larger the damage ratio is, the larger the damage degree of the workpiece is; if the damage degree is represented by the number of dislocations and the damage ratio, the higher the number of dislocations and the larger the damage ratio, the larger the damage degree of the workpiece. The workpiece damage repairing device can calculate the dislocation number of the workpiece according to the grain size of the workpiece material, the shear modulus of the workpiece, the atomic distance and the like, wherein the external force applied to the workpiece is related to the working time and the working environment of the workpiece. The workpiece damage repairing device can reduce the number of dislocation and eliminate dislocation jam by improving the temperature and enabling the workpiece to vibrate freely, thereby healing the fatigue damage of the workpiece.
S202, determining vibration parameters based on the damage degree, controlling the waveform generator to generate a preset waveform signal, and sending the preset waveform signal to the vibration exciter.
Specifically, the workpiece damage repairing device can determine vibration parameters based on the damage degree, the vibration parameters can be the frequency and the amplitude of free vibration of the workpiece, and the workpiece can achieve the purpose of damage repairing after free vibration meeting the vibration parameters. It can be understood that the larger the damage degree of the workpiece, that is, the larger the dislocation number, if want to reach similar damage repair effect in the same time, the larger the frequency and amplitude of the required free vibration, so the vibration parameter and the damage degree, that is, the dislocation number is in a direct proportion relation, the workpiece damage repair device can search the vibration correspondence table of the damage degree and the vibration parameter, search the vibration parameter corresponding to the damage degree in the vibration correspondence table, and control the waveform generator to generate the preset waveform signal, send the preset waveform signal to the vibration exciter, and the preset waveform signal can indicate the vibration exciter to generate the vibration meeting the vibration parameter.
The vibration correspondence table can be preset and stored in the workpiece damage repair device by related maintenance personnel of the workpiece, the vibration correspondence table can be set by the related maintenance personnel according to previous workpiece repair experience, and the vibration correspondence table of the damage degree and the vibration parameter can be calculated according to the stored historical vibration parameter and the corresponding historical damage degree in the workpiece damage repair device. For example, if the workpiece damage repair device detects that the number of dislocations is 37 in the damage parameters of the workpiece, the vibration corresponding to the number of dislocations 37 is found by looking up the vibration mapping table, for example, the vibration frequency corresponding to the number of dislocations 37 may be 60Hz, and the vibration amplitude corresponding to the number of dislocations may be 3 g.
Optionally, the workpiece damage repairing device may store a historical damage degree of the workpiece and a historical vibration parameter of the generated free vibration during damage repairing each time, and the workpiece damage repairing device may calculate a functional relationship between the damage degree and the vibration parameter according to the historical damage degree and the historical vibration parameter, and generate a vibration correspondence table of the damage degree and the vibration parameter according to the functional relationship.
It can be understood that the workpiece is placed on the vibration exciter to vibrate freely along with the vibration exciter, the stable free vibration can enable the damage repairing effect of the workpiece to be better, and the preset waveform signal can be a sine waveform signal in order to enable the vibration exciter to generate stable vibration.
Optionally, the workpiece damage repairing device may send the preset waveform signal to the power amplifier after the waveform generator generates the preset waveform signal, the power amplifier generates an amplified waveform signal based on the preset waveform signal, and then sends the amplified waveform signal to the vibration exciter, and the amplified waveform signal may indicate the vibration exciter to generate vibration satisfying the vibration parameter.
And S203, controlling the vibration exciter to vibrate based on the preset waveform signal, so that the workpiece can vibrate freely.
Specifically, after the vibration exciter receives a preset waveform signal or a method waveform signal, vibration meeting vibration parameters can be generated, and the workpiece can freely vibrate along with the vibration exciter because the workpiece is arranged on the vibration device.
Referring to fig. 4 together, an exemplary schematic diagram of automatic vibration of a workpiece is provided for an embodiment of the present application, a waveform generator, a power amplifier and a vibration exciter constitute a vibration device, the waveform generator is connected to the power amplifier, the waveform generator generates a preset waveform signal and sends the preset waveform signal to the power amplifier, the power amplifier generates an amplified waveform signal based on the preset waveform signal, the power amplifier is connected to the vibration exciter, the power amplifier sends the amplified waveform signal to the vibration exciter, the vibration exciter generates vibration satisfying vibration parameters according to the amplified waveform signal, the workpiece is placed on the vibration exciter, and the workpiece freely vibrates along with the vibration exciter.
And S204, acquiring an expected temperature corresponding to the damage degree based on the proportional relation between the temperature parameter and the damage degree.
Specifically, the temperature parameter indicates the environmental temperature in the damage repairing process, the higher the environmental temperature is, the faster the atomic movement speed of the material of the workpiece in the damage repairing process is, so the temperature parameter and the damage degree are in a direct proportion relation, and the workpiece damage repairing device can search a temperature correspondence table of the damage degree and the expected temperature, and search the expected temperature corresponding to the damage degree. The temperature corresponding table can be preset by related maintenance personnel of the workpiece and stored in the workpiece damage repair device, the temperature corresponding table can be set by the related maintenance personnel according to previous workpiece repair experience, and the temperature corresponding table of the damage degree and the expected temperature can be calculated according to historical expected temperature and corresponding historical damage degree stored in the workpiece damage repair device.
It is understood that the damage degree includes at least one of the number of dislocations and the damage ratio, so the calculation manner of the temperature correspondence table includes, but is not limited to, the following three:
in a first feasible implementation manner of the embodiment of the present application, if the damage degree obtained by the workpiece damage repair device includes both the dislocation number and the damage ratio, the workpiece damage repair device may store the historical damage ratio and the historical dislocation number of the workpiece and the used historical expected temperature each time the damage repair is performed, and the workpiece damage repair device may calculate a functional relationship between the damage degree and the temperature parameter according to the historical damage ratio, the historical dislocation number and the historical expected temperature, and generate a temperature correspondence table between the damage degree and the expected temperature according to the functional relationship;
in a first possible implementation manner of the embodiment of the present application, if the damage degree obtained by the workpiece damage repair device is the dislocation number, the workpiece damage repair device may store the historical dislocation number of the workpiece and the used historical expected temperature each time the damage repair is performed, the workpiece damage repair device may calculate a functional relationship between the dislocation number and the temperature parameter according to the historical dislocation number and the historical expected temperature, and generate a temperature correspondence table between the dislocation number and the expected temperature according to the functional relationship;
in a first possible implementation manner of the embodiment of the present application, if the damage degree obtained by the workpiece damage repair device is a damage ratio, the workpiece damage repair device may store a historical damage ratio of the workpiece and a historical expected temperature used in each damage repair, and the workpiece damage repair device may calculate a functional relationship between the damage ratio and the temperature parameter according to the historical damage ratio and the historical expected temperature, and generate a temperature correspondence table between the damage ratio and the expected temperature according to the functional relationship. Taking the third method as an example to obtain the temperature correspondence table, it can be understood that the value range of the damage proportion in the damage degree is 0-1, so the correspondence relationship between the damage degree and the expected temperature is set to be a linear relationship, the workpiece damage repair device can set the value range of the expected temperature to be 20-K ℃, wherein K ℃ is the material melting point of the workpiece, so the corresponding expected temperature is 20 ℃ when the damage proportion is 0, and the corresponding expected temperature is K ℃, namely the material melting point, when the damage proportion is 1, and the damage proportion and the expected temperature are in a linear relationship.
S205, judging whether the expected temperature is more than one half of the melting point of the material.
Specifically, in order to improve the damage repair efficiency and simultaneously protect the mechanical properties of the workpiece from being changed, it is necessary to ensure that the temperature indicated by the temperature parameter is less than or equal to one half of the melting point of the material, so that after the workpiece repair device obtains the expected temperature corresponding to the damage degree, it is also necessary to determine whether the expected temperature is greater than one half of the melting point of the material, and if not, S206 is executed; if yes, go to S207.
S206, determining the expected temperature as the temperature indicated by the temperature parameter.
Specifically, if the desired temperature is less than or equal to one-half of the melting point of the material, the workpiece damage repair device may identify the desired temperature as the temperature indicated by the temperature parameter.
And S207, determining one half of the melting point of the material as the temperature indicated by the temperature parameter.
