Further, in order to realize accurate measurement of the cutter, an included angle formed between the first laser and the second laser is 90 degrees. Therefore, when the first laser and the second laser are used as measuring light, the cutter can move along a third direction which forms an included angle of 45 degrees with the first laser and the second laser, and the first laser and the second laser can jointly measure the size of the cutter.
As shown in fig. 3, 4 and 5, the tool setting method of the machining equipment using the tool setting device 100 includes a first tool setting mode, a second tool setting mode and a third tool setting mode, and a user may select different tool setting modes as needed.
Referring to fig. 3, when the machining apparatus is in the first tool setting mode, the first pair of tool assemblies 40 and the second pair of tool assemblies 60 operate simultaneously, the first laser light emitted by the first pair of tool assemblies 40 is used as the measuring light to measure the dimension of the tool, and the second laser light is used as the detecting light to detect and compensate the error.
Specifically, the first pair of knife modes comprises the following steps:
s110: a first laser light extending in a first direction and a second laser light extending in a second direction are simultaneously emitted.
Specifically, the first transmitting unit 41 transmits the first laser beam to the first receiving unit 43, the second transmitting unit 61 transmits the second laser beam to the second receiving unit 63, the first laser beam and the second laser beam have an intersection point, and an included angle formed between the first laser beam and the second laser beam is 90 °.
S120: the tool is controlled to move in a second direction to pass through the first laser.
Specifically, the cutter rotating at a high speed is controlled to vertically pass through the first laser along the second direction, and the cutter passes through the intersection point of the first laser and the second laser in the moving process.
S130: and acquiring the position coordinates of the cutter relative to the first laser and the second laser in the moving process.
Specifically, when the tool moves in the second direction and passes through the first laser, the first laser is blocked from reaching the first receiving unit 43 to generate an electrical signal, and therefore, the position coordinate of the tool before passing through the first laser and the position coordinate of the tool after passing through the first laser can be obtained from the electrical signal.
Further, since the tool may vibrate in the first direction during the movement of the tool in the second direction, the moving path of the tool is not a straight line but a curve, and the second laser is used as the inspection light to measure the position coordinates of the tool in the first direction, and determine whether there is a shift or a break in the first direction during the movement of the tool in the second direction.
S140: and obtaining the size of the tool according to the position coordinates of the tool relative to the first laser and the second laser in the moving process.
Specifically, the approximate size of the tool is obtained by calculating the difference between the position coordinate of the tool before the tool passes through the first laser and the position coordinate of the tool after the tool passes through the first laser, meanwhile, the position coordinate of the tool relative to the second laser is obtained to obtain the error caused by mechanical oscillation, and the two data are combined for matching, so that the size of the tool is finally and accurately obtained.
Therefore, in the first pair of cutting modes, the second laser can be used as inspection light, so that whether the cutter is broken or not and whether the error of the cutter caused by oscillation exceeds the range or not can be conveniently inspected. It will be appreciated that in other embodiments, the first laser may be used as the inspection light and the second laser may be used as the measurement light.
Referring to fig. 4, when the machining apparatus is in the second tool setting mode, the first pair of tool assemblies 40 and the second pair of tool assemblies 60 work simultaneously to measure the dimension of the tool, thereby effectively improving the measurement accuracy.
Specifically, the second pair of knife modes comprises the following steps:
s210: the first laser and the second laser are emitted simultaneously.
Specifically, the first transmitting unit 41 transmits the first laser beam to the first receiving unit 43, the second transmitting unit 61 transmits the second laser beam to the second receiving unit 63, the first laser beam and the second laser beam have an intersection point, and an included angle formed between the first laser beam and the second laser beam is 90 °.
S220: and controlling the cutter to move along the third direction so as to simultaneously pass through the first laser and the second laser.
Specifically, the cutter rotating at a high speed is controlled to move along a third direction forming an included angle of 45 degrees with the first laser or the second laser, so that the cutter simultaneously penetrates through and penetrates out of the first laser and the second laser, and the cutter passes through an intersection point of the first laser and the second laser in the moving process.
S230: and acquiring the position coordinates of the cutter relative to the first laser and the second laser in the moving process.
Specifically, when the tool moves in the second direction and passes through the first laser, the first laser is blocked from reaching the first receiving unit 43 to generate an electrical signal, and therefore, the position coordinate of the tool before passing through the first laser and the position coordinate of the tool after passing through the first laser can be obtained from the electrical signal.
Accordingly, when the tool moves in the first direction and passes through the second laser, the second laser is blocked from reaching the second receiving unit 63 to generate an electrical signal, and thus the position coordinate of the tool before passing through the second laser and the position coordinate of the tool after passing through the second laser can be obtained according to the electrical signal.
S240: and obtaining the size of the tool according to the position coordinates of the tool relative to the first laser and the second laser in the moving process.
Specifically, the size of the tool may be calculated according to a difference between a position coordinate of the tool before passing through the first laser and a position coordinate of the tool after passing through the first laser, and a difference between a position coordinate of the tool before passing through the second laser and a position coordinate of the tool after passing through the second laser. In the calculation process of the size of the cutter, the position coordinate of any point position on the cutter relative to the first laser and the position coordinate of any point position relative to the second laser in the moving process can be obtained, and whether the point position has deviation in the moving process is calculated by utilizing the pythagorean theorem, so that the measurement precision and the measurement accuracy are ensured.
Therefore, under the second pair of cutting modes, the sizes of the cutting tools are measured simultaneously by using the first laser and the second laser, so that the cutting tool setting accuracy and the measuring accuracy are improved to a great extent, and the processing accuracy of processing equipment is ensured.
As shown in fig. 5, when the machining apparatus is in the second tool setting mode, only the first pair of tool assemblies 40 are operated to measure the dimensions of the tool, simplifying the measurement procedure and increasing the measurement speed without requiring excessive accuracy.
Specifically, the third tool setting mode includes the following steps:
s310: a first laser is emitted.
Specifically, the first transmitting unit 41 transmits the first laser light to the first receiving unit 43 while the first laser light is in an off state.
S320: the tool is controlled to move in a second direction to pass through the first laser.
Specifically, the cutter which controls the high-speed rotation vertically passes through the first laser along the second direction.
S330: and acquiring the position coordinates of the cutter relative to the first laser in the moving process.
Specifically, when the tool moves in the second direction and passes through the first laser, the first laser is blocked from reaching the first receiving unit 43 to generate an electrical signal, and therefore, the position coordinate of the tool before passing through the first laser and the position coordinate of the tool after passing through the first laser can be obtained from the electrical signal.
S340: and obtaining the size of the tool according to the position coordinate of the tool relative to the first laser in the moving process.
Specifically, the size of the tool is obtained by calculating the difference between the position coordinate of the tool before the tool passes through the first laser and the position coordinate of the tool after the tool passes through the first laser.
It is understood that in the third pair of knife modes, the second pair of knife assemblies 60 can also be controlled to be in an operating state, the second emitting unit 61 emits the second laser, and the knife is controlled to move in the first direction to pass through the second laser to obtain the size of the knife.
In some embodiments, the tool setting mode further includes the following steps:
s410: when the first laser is interrupted, the second laser is emitted.
Specifically, when the machining device is in the first tool setting mode or the second tool setting mode, and when the first tool setting assembly 40 fails, the second tool setting assembly 60 may continue to operate in the third tool setting mode, and the second transmitting unit 61 transmits the second laser to the second receiving unit 63. When the processing tool is in the third pair of knife modes, if the first pair of knife assemblies 40 fails, the second pair of knife assemblies 60 begins to operate.
S420: the tool is controlled to move in a first direction to pass through the second laser.
Specifically, the cutter rotating at a high speed is controlled to vertically pass through the second laser along a first direction.
S430: and acquiring the coordinate position of the cutter relative to the second laser in the moving process.
Specifically, when the tool moves in the first direction and passes through the second laser, the second laser is blocked from reaching the second receiving unit 63 to generate an electrical signal, and therefore, the position coordinate of the tool before passing through the second laser and the position coordinate of the tool after passing through the second laser can be obtained according to the electrical signal.
S440: and obtaining the size of the tool according to the position coordinate of the tool relative to the second laser in the moving process.
Specifically, the size of the tool is obtained by calculating the difference between the position coordinate of the tool before passing through the second laser and the position coordinate of the tool after passing through the second laser.
In this way, when the first pair of tool assemblies 40 fails, the second pair of tool assemblies 60 can continue to perform measurement, so that the machining equipment is prevented from stopping working and obvious fracture marks are formed on the surface of the workpiece, and the machining precision of the workpiece is ensured.
Similarly, the tool setting mode comprises the following steps:
s510: when the second laser is interrupted, the first laser is emitted.
Specifically, when the processing equipment is in the first tool setting mode or the second tool setting mode, and when the second pair of tool assemblies 60 fails, the first pair of tool assemblies 40 may continue to operate in the third tool setting mode, and the first transmitting unit 41 transmits the second laser light to the second receiving unit 43. When the machining apparatus is in the third pair of knife modes, if the second pair of knife assemblies 60 fails, the first pair of knife assemblies 40 begins to operate.
S420: the tool is controlled to move in a second direction to pass through the first laser.
Specifically, the cutter which controls the high-speed rotation vertically passes through the first laser along the second direction.
S430: and acquiring the coordinate position of the cutter relative to the first laser in the moving process.
Specifically, when the tool moves in the second direction and passes through the first laser, the first laser is blocked from reaching the first receiving unit 43 to generate an electrical signal, and therefore, the position coordinate of the tool before passing through the first laser and the position coordinate of the tool after passing through the first laser can be obtained from the electrical signal.
S440: and obtaining the size of the tool according to the position coordinate of the tool relative to the first laser in the moving process.
Specifically, the size of the tool is obtained by calculating the difference between the position coordinate of the tool before the tool passes through the first laser and the position coordinate of the tool after the tool passes through the first laser.
In this way, when the second pair of tool assemblies 60 fails, the first pair of tool assemblies 40 can continue to perform measurement, so that the machining equipment is prevented from stopping working and obvious fracture marks are formed on the surface of the workpiece, and the machining precision of the workpiece is ensured.
According to the tool setting device 100, the machining equipment and the tool setting control method, an operator can select different modes to set tools according to needs so as to meet different machining requirements. Under the first cutter aligning mode, the first laser is used as measuring light, the second laser can be used as inspection laser, whether the cutter is broken or not and whether the error of the cutter caused by oscillation exceeds the range or not can be conveniently inspected, and the cutter aligning precision is effectively improved. In the second pair of cutting modes, the sizes of the cutting tools can be simultaneously measured by utilizing the first laser and the second laser, so that the cutting tool setting precision and the measuring accuracy are improved to a great extent, and the processing precision of processing equipment is ensured. In addition, when the first pair of cutter assemblies 40 or the second pair of cutter assemblies 60 break down, the second pair of cutter assemblies 60 or the first pair of cutter assemblies 40 can continue to work, so that the machining equipment is prevented from stopping working and obvious fracture marks are formed on the surface of the workpiece, and the machining precision of the workpiece is ensured.
