Description

Technical Field

[0001] The invention relates to the technical field of automobile parts processing, in particular to a cutting tool and a cutting method. Background Art

[0002] There are many scenarios of groove processing in the automotive parts processing. At present, the groove is processed by using cutting tools with blade sizes equivalent to the groove size and cooperating with machine tool control. During the processing, metal chips generated by cutting are easily stuck in the groove, resulting in the problem that the processing quality of the groove does not meet the requirements.

[0003] For example, refer to Figure 1 As shown, the outer wall of the guide rod hole 11 of the caliper bracket 10 of the brake caliper needs to be processed with an annular sealing groove 12, and the annular sealing groove 12 is used to install a sealing ring, and the sealing ring cooperates with the assembly component to achieve sealing protection for the guide rod hole 11. During braking, the guide rod slides in the guide rod hole 11, driving the brake assembly to move axially, so that the friction plate presses the brake disc to achieve braking.

[0004] However, currently, in the processing process of the annular sealing groove 12, chip jamming problems often occur, resulting in the inability to accurately install the sealing ring, causing sealing failure, and then causing water to enter the guide rod hole 11 and rust, affecting the guide rod sliding, and ultimately affecting the braking performance of the brake caliper, posing a hidden danger to driving safety.

[0005] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0006] In view of this, the present invention provides a cutting tool and a cutting method, which can effectively solve the problem that metal chips are stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements.

[0007] According to one aspect of the present invention, there is provided a cutting tool, which is equipped with a plurality of blades, wherein: the cutting width of the cutting edge of each blade is smaller than a target width, the cutting edges of the plurality of blades form a staggered tooth structure which is staggered in the target width direction and has an overlapping area, and the effective cutting width of the staggered tooth structure in the target width direction is equal to the target width.

[0008] The cutting tool of the present invention makes the cutting width of the cutting edge of each blade smaller than the target width, so that the width of the metal chips produced by each blade cutting is smaller than the target width of the groove to be processed, thereby reducing the possibility of the metal chips produced by cutting being stuck in the groove; by cutting with multiple blades whose cutting edges are smaller than the target width, on the one hand, the blade wear is reduced, the cutting ability and life of the tool are improved, and the product processing efficiency and product processing cost are improved, and on the other hand, the processing process is made more stable and controllable, and the processing reliability is improved. The cutting edges of multiple blades are staggered and arranged in the target width direction and have overlapping areas, so that the cutting edges of multiple blades form an overlapping staggered tooth structure in the processing area, so that when the cutting tool is running, the cutting edges of the staggered tooth structure cross-cut the groove, so that while cutting the groove, each blade can break the metal chips produced by other blades in the target width direction, so that the cut metal chips are easy to fall off, and the metal chips are effectively prevented from being stuck in the groove. In addition, the effective cutting width of the cutting edge of the staggered tooth structure is equal to the target width of the groove to be processed, ensuring that the groove required for forming is processed by multiple blades.

[0009] Thus, the cutting tool of the present invention forms a staggered tooth structure by staggering and overlapping the cutting edges of multiple blades, so that when the cutting tool is running, the cutting edges of the staggered tooth structure cross-cut the groove to be processed in the target width direction, and break the metal chips generated by the cutting in the target width direction at the same time, effectively solving the problem of metal chips getting stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements, which can improve the product processing quality and enhance the production line production efficiency and capacity.

[0010] In some embodiments, cutting edges of adjacent blades among the plurality of blades are staggered in the target width direction and have overlapping areas.

[0011] In this way, the cutting edges of adjacent blades form an overlapping staggered tooth structure in the processing area, so that during the groove processing, the rear blade can promptly break the metal chips generated by the front blade in the target width direction to prevent the metal chips from getting stuck in the groove.

[0012] In some embodiments, the cutting edges of the plurality of blades are staggered with each other in the target width direction and have overlapping areas with each other.

[0013] In this way, the cutting edge of each blade is staggered and overlapped with the cutting edges of the remaining blades in the target width direction, so that during the groove processing, each blade can break the metal chips generated by the cutting of the remaining blades in the target width direction, effectively preventing the metal chips from getting stuck in the groove.

[0014] In some embodiments, the installation positions of the plurality of blades are staggered in the target width direction, and / or the cutting edges of the plurality of blades are different, so that the cutting edges of the plurality of blades are staggered in the target width direction.

[0015] The cutting edges of the plurality of blades are staggered in the target width direction by staggering the installation positions of the plurality of blades in the target width direction and / or by different cutting edges of the plurality of blades.

[0016] In some embodiments, a cutting width of a cutting edge of each of the blades is greater than 50% of the target width and less than or equal to 90% of the target width.

[0017] In this way, each blade cuts an appropriate amount of the groove area, which can not only break the metal chips generated by cutting, but also ensure the processing efficiency and the smoothness and controllability of the processed surface of the groove.

[0018] In some embodiments, the plurality of blades are mounted on the cutting tool at intervals along a circumferential direction.

[0019] In this way, the cutting tool can process the annular groove by rotary cutting, for example, the annular sealing groove on the outer wall of the guide rod hole of the caliper bracket can be processed.

[0020] In some embodiments, the blades include two blades, wherein, in the target width direction: the cutting edge of the first blade is aligned with the first side of the target width and is indented relative to the second side of the target width; the cutting edge of the second blade is aligned with the second side of the target width and is indented relative to the first side of the target width.

[0021] The cutting edges of the two blades are aligned with one side of the target width and indented relative to the other side of the target width, so that the two blades can cross-cut through the cutting edges of the staggered tooth structure to complete the groove processing during the operation of the cutting tool, and the two blades can break the metal chips generated by each other's cutting in the direction of the target width, so that the cut metal chips are easier to fall off, effectively solving the problem of metal chips getting stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements.

[0022] In some embodiments, the two blades are identical, and each blade has a first cutting edge and a second cutting edge located at two ends; wherein the first cutting edge and the second cutting edge form the cutting edge of the first blade and the cutting edge of the second blade respectively.

[0023] The two blades are completely identical, which can facilitate the design, manufacture and management of the blades; when installing the blades, only one blade needs to be installed upright with its first cutting edge facing the front of the cutting tool to form a cutting edge, and the other blade needs to be installed reversely with its second cutting edge facing the front of the cutting tool to form a cutting edge.

[0024] In some embodiments, the first blade and the second blade are installed symmetrically about the axis of the cutting tool, and the cutting tool is used to process the annular sealing groove of the caliper bracket.

[0025] The two blades are symmetrically installed about the axis of the cutting tool, so that the cutting tool structure is stable and the cutting is uniform, so as to process the annular sealing groove of the caliper bracket with high quality and avoid sealing failure caused by metal chips stuck in the annular sealing groove, ensuring that the braking function of the brake caliper is stably and accurately realized.

[0026] According to another aspect of the present invention, there is provided a cutting method, which is implemented based on the cutting tool described in any of the above embodiments, and the cutting method comprises: determining a target width according to the size of a groove to be processed; installing a plurality of blades on the cutting tool according to the target width, wherein the cutting width of the cutting edge of each blade is smaller than the target width, so that the cutting edges of the plurality of blades form a staggered tooth structure which is staggered in the direction of the target width and has an overlapping area, and the effective cutting width of the staggered tooth structure in the direction of the target width is equal to the target width; installing the cutting tool on a machine tool, and controlling the cutting tool to automatically run by the machine tool, wherein, as the cutting tool runs, the plurality of blades cross-cut the groove to be processed through the cutting edges of the staggered tooth structure.

[0027] The cutting tool is automatically controlled by the machine tool, and the staggered tooth structure of the cutting edges of multiple blades is used to cross-cut and cut the groove to be processed. While cutting the groove, each blade can break the metal chips produced by other blades in the target width direction, making it easy for the cut metal chips to fall off, effectively preventing the metal chips from getting stuck in the groove and ensuring that the groove is cut in place.

[0028] The beneficial effects of the present invention compared with the prior art include at least: The cutting tool of the present invention forms a staggered tooth structure by staggering and overlapping the cutting edges of multiple blades, so that when the cutting tool is running, the cutting edges of the staggered tooth structure cross-cut the groove to be processed in the target width direction, and at the same time break the metal chips generated by the cutting in the target width direction, effectively solving the problem of metal chips getting stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements, which can improve the product processing quality and enhance the production line production efficiency and capacity.

However, example embodiments can be implemented in a variety of forms and should not be construed as limited to the embodiments described herein. Instead, these embodiments are provided to make the present invention more comprehensive and complete and to fully convey the concepts of the example embodiments to those skilled in the art.

[0033] The accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the drawings represent the same or similar parts, and thus their repeated description will be omitted.

[0034] The processes shown in the accompanying drawings are only exemplary and do not necessarily include all the steps. For example, some steps can be decomposed, some steps can be combined or partially combined, and the order of actual execution may change according to the actual situation. The words "first", "second" and similar words used in the specific description do not indicate any order, quantity or importance, but are only used to distinguish different components. The orientation or position relationship indicated by the terms "upper", "lower", "left", "right", etc. is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In addition, in the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0035] It should be noted that, in the absence of conflict, the embodiments of the present invention and features in different embodiments may be combined with each other.

[0036] Figure 2 The structure of the cutting tool is shown in figure. Figure 3 The structure of the cutting tool blade is shown; combined Figure 2 and Figure 3 As shown, the cutting tool 20 provided by the embodiment of the present invention is equipped with multiple blades 22, wherein: the cutting width of the cutting edge 220 of each blade 22 is smaller than the target width W, and the cutting edges 220 of the multiple blades 22 form a staggered tooth structure that is staggered in the target width direction and has an overlapping area, and the effective cutting width of the staggered tooth structure in the target width direction is equal to the target width W.

[0037] For example, Figure 2 and Figure 3 Taking the example shown in the figure, in a specific example, the cutting tool 20 is configured with two blades 22, wherein the cutting width of the cutting edge 220 of one blade 22 is W1, and the cutting width of the cutting edge 220 of the other blade 22 is W2, and W1 and W2 satisfy: W1<W, W2<W, W1 and W2 are staggered and partially overlapped in the target width direction, and the sum of the projections of W1 and W2 in the target width direction, that is, the effective cutting width of the cutting edges 220 of the two blades 22 combined in the target width direction, is equal to the target width W.

[0038] It should be noted that the cutting tool 20 may also be configured with other numbers of blades, and each blade may be arranged in other ways, as long as the cutting width of the cutting edge 220 of each blade 22 is less than the target width W, the cutting edges 220 of the plurality of blades 22 form a staggered tooth structure that is staggered in the target width direction and has an overlapping area, and the effective cutting width of the staggered tooth structure in the target width direction is equal to the target width W, instead of Figure 2 and Figure 3 Limits shown.

[0039] The cutting tool 20 of the present invention makes the cutting width of the cutting edge 220 of each blade 22 smaller than the target width W, so that the width of the metal chips produced by each blade 22 is smaller than the target width W of the groove to be processed, thereby reducing the possibility of the metal chips produced by cutting being stuck in the groove; by cutting with multiple blades 22 whose cutting edges 220 are smaller than the target width W, on the one hand, the wear of the blade 22 is reduced, the cutting ability and life of the tool are improved, and the product processing efficiency and product processing cost are improved, and on the other hand, the processing process is made more stable and controllable, and the processing reliability is improved. The cutting edges 220 of multiple blades 22 are staggered and arranged in the target width direction and have overlapping areas, so that the cutting edges 220 of multiple blades 22 form a staggered tooth structure with overlapping processing areas, so that when the cutting tool 20 is running, the cutting edges 220 of the staggered tooth structure cross-cut the groove, so that while cutting the groove, each blade 22 can break the metal chips produced by other blades 22 in the target width direction, so that the cut metal chips are easy to fall off, and the metal chips are effectively prevented from being stuck in the groove. In addition, the effective cutting width of the cutting edge 220 of the staggered tooth structure is equal to the target width W of the groove to be processed, ensuring that the required groove can be processed and formed by multiple blades 22 .

[0040] Thus, the cutting tool 20 of the present invention forms a staggered tooth structure by staggering and overlapping the cutting edges 220 of multiple blades 22, so that when the cutting tool 20 is running, the cutting edges 220 of the staggered tooth structure cross-cut the groove to be processed in the target width direction, and break the metal chips generated by cutting in the target width direction at the same time, effectively solving the problem of metal chips getting stuck in the groove during groove processing, resulting in the groove processing quality not meeting the requirements, which can improve product processing quality and enhance production line production efficiency and capacity.

[0041] According to the design requirements, the groove to be processed can be a linear groove, annular groove, etc., which can be processed by the cutting tool 20 of the present invention. During specific processing, the cutting tool 20 can be installed on a machine tool, and the machine tool controls the cutting tool 20 to automatically run to achieve cutting processing of the groove.

[0042] For example, refer to Figure 4 The structure of the groove to be processed is shown in FIG. Figure 5 and Figure 6 The schematic diagram shows the structure of the cutting tool for cross cutting of the groove to be machined, combined with Figure 2 and Figure 3As shown in the figure: In a specific example, the groove 12' to be processed is an annular groove, and its target width is W; the cutting tool 20 is controlled by the machine tool to perform external cutting while rotating, so as to process the groove 12' to be processed. During the operation of the cutting tool 20, the cutting edges 220 of the two blades 22 perform cross cutting on the groove 12' to be processed in the target width direction, wherein Figure 5 It is shown that the cutting edge 220 with a cutting width W1 cuts the groove 12' to be processed. Figure 6 It is shown that the cutting edge 220 with a cutting width of W2 cuts the groove 12' to be processed; the staggered tooth structure formed by the cutting edges 220 of the two blades 22 cross-combines the groove 12' to be processed, which not only realizes the processing of the groove but also breaks the metal chips generated in the cutting process to prevent the metal chips from being stuck in the groove, thereby ensuring that the groove 12' to be processed is cut in place.

[0043] Continue to combine Figures 2 to 6 As shown, in some embodiments, the cutting edges 220 of adjacent blades in the plurality of blades 22 are staggered in the target width direction and have overlapping areas.

[0044] In this way, the cutting edges 220 of adjacent blades form an overlapping staggered tooth structure in the processing area, so that during the groove processing, the rear blade can promptly break the metal chips generated by the front blade in the target width direction to prevent the metal chips from being stuck in the groove.

[0045] Non-adjacent blades can be arranged in a suitable manner such as staggered arrangement in the target width direction with overlapping areas, staggered arrangement in the target width direction without overlapping areas, and aligned arrangement in the target width direction, according to design requirements. For example, in some specific examples, the cutting edges 220 of adjacent blades are arranged alternately in the target width direction so that the processing areas of the blades with two types of cutting edges overlap, but the invention is not limited thereto.

[0046] In some embodiments, the cutting edges 220 of the plurality of blades 22 are staggered in the target width direction and have overlapping areas.

[0047] In this way, the cutting edge 220 of each blade 22 is staggered and overlapped with the cutting edges 220 of the remaining blades 22 in the target width direction, so that each blade 22 can break the metal chips generated by cutting by the remaining blades 22 in the target width direction during the groove processing, effectively preventing the metal chips from getting stuck in the groove.

[0048] In some examples, the cutting tool 20 is installed with three blades 22, and the cutting edges 220 of the three blades 22 are arranged in sequence in the target width direction, wherein the cutting width of the last blade covers most of the cutting width of the previous blade and covers part of the cutting width of the first blade, so that the cutting edges 220 of the three blades 22 form a staggered tooth structure in which they are staggered and the processing areas overlap with each other, but this is not limited to this.

[0049] In some embodiments, the installation positions of the plurality of blades 22 are staggered in the target width direction, and / or the cutting edges 220 of the plurality of blades 22 are different, so that the cutting edges 220 of the plurality of blades 22 are staggered in the target width direction.

[0050] The cutting edges 220 of the plurality of blades 22 are staggered in the target width direction by staggering the installation positions of the plurality of blades 22 in the target width direction and / or by different cutting edges 220 of the plurality of blades 22 .

[0051] Considering the convenience and stability of the design and assembly of the cutting tool 20, the positions of the mounting grooves on the cutting tool 20 for mounting each blade 22 can be aligned in the target width direction, while the cutting edges 220 of each blade 22 fall at different positions in the target width direction. In this way, the cutting edges 220 of multiple blades 22 are staggered in the target width direction, but this is not limited to this.

[0052] In some embodiments, the cutting width of the cutting edge 220 of each blade 22 is greater than 50% of the target width W and less than or equal to 90% of the target width W.

[0053] In this way, each blade 22 cuts an appropriate amount of the groove area, which can not only break the metal chips generated by cutting, but also ensure the processing efficiency and the smoothness and controllability of the processed surface of the groove.

[0054] The cutting width of the cutting edge 220 of the blade 22 may be negatively correlated with the number of blades 22, but is not limited thereto. For example, when the cutting tool 20 is configured with two blades 22, the cutting width of the cutting edge 220 of each blade 22 may be 90% of the target width W; when the cutting tool 20 is configured with three blades 22, the cutting width of the cutting edge 220 of each blade 22 may be 70% of the target width W. The cutting width of the cutting edge 220 of each blade 22 may be adjusted according to actual needs, and the cutting widths of the cutting edges 220 of each blade 22 may be the same or different.

[0055] In some embodiments, a plurality of blades 22 are installed on the cutting tool 20 at intervals along the circumferential direction. In this way, the cutting tool 20 can process an annular groove by rotary cutting, for example, an annular sealing groove on the outer wall of the guide rod hole of the caliper bracket can be processed.

[0056] In some embodiments, the blade 22 includes two blades, wherein, in the target width direction: the cutting edge 220 of the first blade 22 is aligned with the first side of the target width W and is indented relative to the second side of the target width W; the cutting edge 220 of the second blade 22 is aligned with the second side of the target width W and is indented relative to the first side of the target width W.

[0057] Among them, Figure 3 Taking the viewing angle as an example, the cutting edge 220 of the upper blade 22 is aligned with the left side of the target width W and indented relative to the right side of the target width W, and the cutting edge 220 of the lower blade 22 is aligned with the right side of the target width W and indented relative to the left side of the target width W.

[0058] The cutting edges 220 of the two blades 22 are respectively aligned with one side of the target width W and are retracted relative to the other side of the target width W, so that the two blades 22 can cross-cut and cut through the cutting edges 220 of the staggered tooth structure during the operation of the cutting tool 20, so as to efficiently and high-quality process the groove with the target width W. During the processing, the two blades 22 respectively break the metal chips generated by cutting in the direction of the target width, so that the cut metal chips are easier to fall off, effectively solving the problem that the metal chips are stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements.

[0059] In some embodiments, the two blades 22 are identical, and each blade 22 has a first edge A and a second edge B located at both ends; wherein the first edge A and the second edge B form a cutting edge 220 of the first blade 22 and a cutting edge 220 of the second blade 22 respectively.

[0060] The two blades 22 are completely identical, which can facilitate the design, manufacture and management of the blades 22; when installing the blades 22, only one blade 22 needs to be installed upright, with its first blade A facing the front of the cutting tool 20 to form a cutting edge 220, and its first blade A is aligned with one side of the target width W, and the other blade 22 needs to be installed in reverse, with its second blade B facing the front of the cutting tool 20 to form a cutting edge 220, and its second blade B is aligned with the other side of the target width W. In this way, the first blade A and the second blade B are staggered in the target width direction and have an overlapping area, and the effective cutting width of the first blade A and the second blade B in the target width direction is equal to the target width W.

[0061] Of course, the cutting tool 20 is not limited to two blades 22, and three blades 22 may be configured to adopt a normal-reverse-normal installation mode, four blades 22 may be configured to adopt a normal-reverse-normal-reverse installation mode, etc. When the cutting tool 20 is in operation, the first blade A and the second blade B cut the groove 12' to be processed through a staggered tooth structure, and the first blade A and the second blade B break the metal chips generated by cutting to prevent the metal chips from being stuck in the groove, thereby efficiently and high-quality cutting to form the required groove, ensuring the processing quality of the product.

[0062] In some embodiments, in combination Figures 1 to 6 As shown, the first blade 22 and the second blade 22 are symmetrically installed about the axis of the cutting tool 20, and the cutting tool 20 is used to process the annular sealing groove 12 of the caliper bracket 10. The groove 12' to be processed is an enlarged structure of the annular sealing groove 12, but is not limited thereto.

[0063] The two blades 22 are symmetrically installed about the axis of the cutting tool 20, so that the cutting tool 20 has a stable structure and uniform cutting, so as to process the annular sealing groove 12 of the caliper bracket 10 with high quality, and avoid sealing failure caused by metal chips stuck in the annular sealing groove 12, thereby ensuring that the braking function of the brake caliper is stably and accurately realized.

[0064] During specific processing, the cutting tool 20 can be controlled by the machine tool to perform external cutting while rotating. During the operation of the cutting tool 20, the cutting edges 220 of the two blades 22 cut the annular sealing groove 12 through the staggered tooth structure, which can not only cut the annular sealing groove 12 but also break the metal chips generated during the cutting process, prevent the metal chips from being stuck in the annular sealing groove 12, and ensure that the annular sealing groove 12 is cut in place. After cutting and forming, the annular sealing groove 12 is used to install a sealing ring, and the sealing ring cooperates with the assembly component to achieve sealing protection for the guide rod hole 11 of the caliper bracket 10, so as to ensure the realization of the braking function of the brake caliper and improve the reliability of the vehicle safety components.

[0065] The embodiment of the present invention further provides a cutting method, which is implemented based on the cutting tool 20 described in any of the above embodiments. The features and principles of the cutting tool 20 described in any of the above embodiments can be applied to the following cutting method embodiments.

[0066] Figure 7 The main steps of the cutting method are shown in figure, combined with Figures 2 to 7 As shown, the cutting method provided by the embodiment of the present invention includes: S710, determining a target width W according to the size of the groove 12' to be processed.

[0067] The target width W is the width of the groove 12 ′ to be processed. The groove 12 ′ to be processed may also be configured with other dimensions such as depth.

[0068] S720, according to the target width W, multiple blades 22 are installed on the cutting tool 20, wherein the cutting width of the cutting edge 220 of each blade 22 is smaller than the target width W, so that the cutting edges 220 of the multiple blades 22 form a staggered tooth structure that is staggered in the target width direction and has an overlapping area, and the effective cutting width of the staggered tooth structure in the target width direction is equal to the target width W.

[0069] The blade 22 can be locked in the mounting slot of the cutting tool 20 by screws.

[0070] S730, installing the cutting tool 20 on the machine tool, and controlling the cutting tool 20 to automatically operate through the machine tool, wherein as the cutting tool 20 operates, the plurality of blades 22 perform cross-cutting on the groove 12' to be processed through the cutting edges 220 of the staggered tooth structure.

[0071] The machine tool may be a lathe. After the cutting tool 20 is installed on the machine tool, the size parameters of the cutting tool 20 and the size parameters of the groove 12' to be processed can be input into the equipment parameters of the machine tool, so that the machine tool can subsequently control the cutting tool 20 to automatically run to achieve cutting of the groove. The workpiece is mounted on the fixture and arranged opposite to the cutting tool 20. After the cutting tool 20 and the workpiece are assembled in place, the processing program of the machine tool can be called and the processing cycle button can be started, so that the machine tool controls the cutting tool 20 to automatically process the groove 12' to be processed of the workpiece.

[0072] The cutting method of the present invention controls the automatic operation of the cutting tool 20 through a machine tool, and utilizes the cutting edges 220 of multiple blades 22 to be staggered and overlapped to form a staggered tooth structure, so that when the cutting tool 20 is running, the cutting edges 220 of the staggered tooth structure cross-cut the groove 12' to be processed in the target width direction, and while cutting, the metal chips generated by the cutting are broken in the target width direction, effectively solving the problem of metal chips getting stuck in the groove during the groove processing, resulting in the groove processing quality not meeting the requirements, which can improve the product processing quality and improve the production efficiency and capacity of the production line.

[0073] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
