In the following description, different "one embodiment" or "another embodiment" refers to not necessarily the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.
The following specifically describes a specific scheme of the electric drill power calculation method and system based on the spindle bias load field analysis, which is provided by the invention, with reference to the accompanying drawings.
Referring to fig. 1, a flow chart illustrating steps of a method for calculating power of a power drill based on a spindle bias load field analysis according to an embodiment of the present invention is shown, wherein the method comprises the following steps:
acquiring the offset distance of an electric drill bit, the internal temperature of the electric drill, the abrasion loss of the electric drill bit and the force applied to the electric drill by personnel based on a preset time interval to obtain an offset distance sequence, an internal temperature sequence, an abrasion loss sequence and a force applying sequence; the applied force is the force applied to the electric drill by a person;
calculating a loss index of the electric drill based on the offset distance sequence and the wear amount sequence;
calculating an aging degree index of the electric drill based on the internal temperature sequence and the loss index;
calculating a service life influence index of the electric drill based on the application force sequence and the aging degree index;
and adjusting the power of the electric drill according to the influence indexes of the service life of the electric drill.
The above steps are specifically described below:
step S1, acquiring the offset distance of the drill bit of the electric drill, the internal temperature of the electric drill, the abrasion loss of the drill bit and the force applied to the electric drill by personnel based on a preset time interval to obtain an offset distance sequence, an internal temperature sequence, an abrasion loss sequence and a force applying sequence; the applied force is a force applied by a person to the drill.
The electric drill can cause the abrasion of the internal bearing after being used for a long time, the bearing abrasion can lead the drill bit to shake when in use, and then the rotation precision of the drill bit is reduced, and the normal working and use of the electric drill can be influenced along with the reduction of the rotation precision. Therefore, the deflectable distance of the drill bit needs to be collected, and it needs to be explained that any position on the drill bit can be selected to obtain the deflectable distance of the drill bit, after the position is selected, the deflectable distance of the drill bit is obtained subsequently based on the position, the position can be a middle position of the drill bit or a drill bit position, and the like, and the deflectable distance of the drill bit is a maximum shaking distance when the drill bit is shaken; preferably, the embodiment obtains the offsetable distance of the drill bit based on the position of the drill bit in contact with the work object. The practitioner may obtain the offsetable distance of the drill bit with the aid of a straightedge or other distance measuring instrument.
Along with the increase of the operation time of the electric drill, the internal temperature of the electric drill continuously rises, the aging of parts inside the electric drill is aggravated, and the service life of the electric drill is influenced by the aging of the parts. Therefore, the internal temperature of the electric drill needs to be collected. The practitioner may use a temperature sensor to obtain the temperature inside the drill.
When the electric drill normally works, under the action of the internal lubricating oil, the abrasion degree of the bearing is slight, but along with the increase of the service life, a large amount of dust is accumulated inside the electric drill, and the lubricating oil is absorbed by the dust, so that the abrasion degree between the bearings is increased during the operation. Therefore, the amount of drill bit wear of the drill is also an important data. The implementer may obtain the drill bit wear amount of the electric drill according to the diameter or radius change of the drill bit in contact with the operation object, specifically, the difference between the currently obtained drill bit diameter and the previously obtained drill bit diameter is the drill bit wear amount, or the difference between the currently obtained drill bit radius and the previously obtained drill bit radius is the drill bit wear amount.
Because the strength and the direction of the electric drill used by a user can directly influence the service life of the drill bit, the force applied to the electric drill by a user is required to be collected. The force applied by the person to the electric drill is a vector and has a magnitude and a direction. In the embodiment, an angle measuring instrument and a pressure measuring instrument are arranged on a handle of the electric drill, wherein the angle measuring instrument is used for measuring an angle between the electric drill and an operation surface, and the pressure measuring instrument is used for measuring the force applied by a person to the electric drill. It should be noted that each element in the acquired force application sequence is a doublet, and the doublet includes the magnitude and direction of the applied force, and the direction is the angle between the drill and the working face.
Therefore, during the operation of the electric drill, the deflectable distance of the drill bit of the electric drill, the internal temperature of the electric drill, the abrasion loss of the drill bit and the force applied to the electric drill by a person are obtained based on the preset time interval, and a deflection distance sequence, an internal temperature sequence, an abrasion loss sequence and a force applied sequence are obtained. Preferably, in the embodiment, the working time is one hour, the preset time interval is ten minutes, and the offset distance sequence, the internal temperature sequence, the wear amount sequence and the force application sequence are acquired.
And step S2, calculating a loss index of the electric drill based on the offset distance sequence and the wear amount sequence.
Calculating a loss index of the electric drill based on the offset distance sequence and the abrasion loss sequence, specifically: acquiring a variance of the offset distance based on the offset distance sequence; acquiring the range of the abrasion loss based on the abrasion loss sequence; carrying out positive correlation mapping on the range to obtain a range mapping value; and the product of the variance and the range mapping value is a loss index of the electric drill. The larger the variance of the offset distance, the larger the range mapping value, indicating the more severe the drill loss.
In one embodiment, the range is mapped positively by using a logarithmic function to obtain a range mapping value. Preferably, the logarithmic function is an ln function.
And step S3, calculating an aging degree index of the electric drill based on the internal temperature sequence and the loss index.
Based on the internal temperature sequence and the loss index, calculating an aging degree index of the electric drill, specifically: obtaining the difference value between each internal temperature in the internal temperature sequence and the room temperature at the corresponding moment to obtain a temperature difference value sequence; acquiring the range of the temperature difference value based on the temperature difference value sequence; and the product of the extreme difference of the temperature difference value and the loss index of the electric drill is the aging degree index of the electric drill. The larger the aging degree index value of the electric drill is, the more serious the electric drill is aged.
Due to different seasons, the temperature rise degree is different in summer and winter, and the temperature rise caused by the operation of the electric drill is obtained by subtracting the room temperature from the internal temperature of the electric drill acquired by the temperature sensor.
And step S4, calculating the influence index of the service life of the electric drill based on the application force sequence and the aging degree index.
Based on the force application sequence and the aging degree index, calculating the service life influence index of the electric drill, specifically comprising the following steps: acquiring a maximum value of the applied force based on the applied force sequence, and acquiring a component force of the maximum value of the applied force in a direction perpendicular to the working surface; calculating a ratio of the component force to the application force maximum; and calculating the service life influence index of the electric drill according to the aging degree index of the electric drill and the ratio. The service life influence index of the electric drill is in an inverse correlation relation with the aging degree index of the electric drill; and the service life influence index of the electric drill is in an inverse correlation with the ratio. The larger the ratio is, the more violent the current personnel use the electric drill; the smaller the value of the influence index of the service life of the electric drill is, the more the service life of the electric drill is influenced by the service state of the current electric drill, and otherwise, the healthier the service state of the current electric drill is.
The force is resolved according to the maximum application force value applied by the electric drill by a person and the angle between the electric drill and the working face corresponding to the maximum application force value, and the component force of the maximum application force value in the direction perpendicular to the working face is obtained.
As an example, the product of the aging degree index of the electric drill and the ratio is obtained, and the reciprocal of the product is the service life influence index of the electric drill.
And step S5, adjusting the power of the electric drill according to the influence index of the service life of the electric drill.
And after the service life influence index of the electric drill is obtained, carrying out normalization processing on the service life influence index of the electric drill, and adjusting the power of the electric drill according to the normalized value.
The threshold value is preset, when the normalized influence index of the service life of the electric drill is larger than the preset threshold value, the current healthier the use state of the electric drill is, the service life of the electric drill is not influenced or not greatly influenced, and at the moment, the power of the electric drill does not need to be adjusted; when the normalized service life influence index of the electric drill is smaller than or equal to the preset threshold value, the fact that the current service state of the electric drill is unhealthy is proved to seriously influence the service life of the electric drill, at the moment, the power of the electric drill needs to be continuously and slowly reduced to enable the electric drill to work at low power or continuously and slowly reduce the power until the electric drill stops working, and the normal working power is recovered after the electric drill works at low power or stops working for a period of time.
