Description

Technical Field

[0001] The invention relates to the technical field of parts fixtures, and in particular to a shockproof fixture for cylindrical parts. Background Art

[0002] At present, some cylindrical parts have features that need to be processed to the same extent around the body. In this regard, the two ends of the cylindrical parts will be positioned and four-axis machine tools will be used for processing. Due to assembly space limitations and cost savings, the cylindrical parts cannot be fixed well, resulting in not only axial rotation but also radial rotation when processing the cylindrical parts. The entire cylindrical part shakes severely, affecting the processing quality.

[0003] In this regard, five-axis machining equipment is currently used to increase machining flexibility. Although five-axis machining equipment can solve the problem of radial and axial shaking of parts, its equipment cost is too expensive and is not conducive to large-scale application. Currently, fixed-angle tooling is used to fix cylindrical parts, which guarantees the angle and accuracy of parts to a certain extent. However, when the swing angle of the part is too large, it is not easy to clamp, and the risk factor increases when the tilt angle is too large. In addition, the universal matching of this kind of tooling is almost zero, and only one set of fixed-angle tooling can be made for one part at one angle, which invisibly increases the tooling cost sharply. Summary of the invention

[0004] The purpose of the present invention is to avoid the shortcomings of the prior art and provide a shockproof fixture for cylindrical parts, which can stably fix the cylindrical parts in an effective space and has a small shielding area for the cylindrical parts, greatly facilitating the processing of the cylindrical parts and having the advantage of low cost.

[0005] To achieve one of the above purposes, the present invention provides the following technical solutions:

[0006] A cylindrical part anti-vibration fixture is provided, comprising a base, a first support block, a second support block, a first pressing block structure and a second pressing block structure.

[0007] The bottom end of the first support block is fixed on the base, and a first V-shaped notch is provided at the top end of the first support block. The large opening of the first V-shaped notch faces upward and is used to support the cylindrical part, wherein the first support block provides a setting position for the first V-shaped notch.

[0008] The bottom end of the second support block is fixed on the base, and a second V-shaped notch is provided at the top end of the second support block. The large opening of the second V-shaped notch faces upward and is used to support the cylindrical part, wherein the second support block provides a setting position for the second V-shaped notch.

[0009] A distance is set between the first V-shaped notch and the second V-shaped notch, and the first V-shaped notch and the second V-shaped notch are relatively aligned, the first pressing block structure is located on the first V-shaped notch, and the second pressing block structure is located on the second V-shaped notch.

[0010] The first V-shaped notch and the second V-shaped notch are aligned with each other, and the first V-shaped notch and the second V-shaped notch can overlap each other by moving along a straight line, so as to support the cylindrical part on the axis and avoid radial rotation of the cylindrical part.

[0011] When positioning the cylindrical part, the two ends of the cylindrical part are respectively mounted on the first V-shaped notch and the second V-shaped notch, and the first pressing block structure and the second pressing block structure extend into the cylindrical part and press the two ends of the cylindrical part.

[0012] When the two ends of the cylindrical part are respectively mounted on the first V-shaped notch and the second V-shaped notch, the cylindrical part still cannot be stably mounted on the first support block and the second support block, and then a related pressing block structure is arranged above the first V-shaped notch and the second V-shaped notch. The pressing block structure will be pressed on the inner wall of the cylindrical part to fix the two ends of the cylindrical part.

[0013] This allows the entire cylindrical part to be stably positioned.

[0014] In some embodiments, the V-shaped angle of the V-shaped opening is greater than 90°.

[0015] When the included angle of the V-shaped opening is greater than 90°, the contact area between the tubular part and the V-shaped opening can be effectively increased, thereby effectively improving the stability of the support.

[0016] In some embodiments, the first pressing block structure and / or the second pressing block structure comprises a retractable vertical rod, a pressing plate is provided on the top of the vertical rod, and the pressing plate extends into the tubular part and presses against the inner wall surface of the end of the tubular part.

[0017] The vertical rod is used to support the pressing plate, and the supporting effect of the vertical rod enables the pressing plate to be pressed better on the two ends of the cylindrical part.

[0018] In some embodiments, the vertical rod is a telescopic rod of a cylinder.

[0019] By using the air cylinder, the pressing plate can be better controlled to press on the inner wall surfaces at both ends of the cylindrical part, or the pressing plate can be kept away from the inner wall surfaces at both ends of the cylindrical part, thereby controlling the fixing or loosening of the cylindrical part.

[0020] The anti-vibration fixture for cylindrical parts according to claim 1 is characterized in that a support seat is also provided on the base, and the support seat supports the outer wall surface of the middle part of the cylindrical part.

[0021] The support seat can better support the middle outer wall surface of the cylindrical part, avoid the problem of the middle part of the cylindrical part sagging due to excessive weight, improve the stability of the entire cylindrical part, and prevent the cylindrical part from deformation.

[0022] In some embodiments, the support seat includes a curved panel, and the curved panel is attached to the middle outer wall surface of the tubular part.

[0023] The curved panel can be well fitted with the outer wall surface of the cylindrical part, thereby improving the support stability.

[0024] In some embodiments, the arcuate concave surface of the arc panel fits with the middle outer wall surface of the tubular part, and the arched surface of the arc panel is fixed on a positioning plate, and the positioning plate is arranged on the base.

[0025] To further improve the fixing stability of the curved panel, the curved concave surface of the curved panel is directed toward the outer wall of the cylindrical part, and then the arched surface of the curved panel is set on a positioning plate, which is used to position the entire curved panel.

[0026] In some embodiments, the base includes a substrate, and slide rails are provided on both end sides of the substrate. A slide plate slides on the slide rails, and the pressing block structure and the supporting block are both fixed on the slide plate.

[0027] A slide rail is provided on the base plate to facilitate setting a slide plate on the rail. The pressing block structure and the supporting block arranged on the slide plate can be displaced along with the movement of the slide plate to adapt to different cylindrical parts or to further move the entire cylindrical part.

[0028] In some embodiments, two ends of the positioning plate are respectively fixed to the slide plates on two end sides of the base plate.

[0029] The positioning plate is also positioned on the slide plate so that it can move with the sliding movement, thereby achieving real-time support of the middle position of the cylindrical part.

[0030] In some embodiments, the two ends of the tubular part are provided with peripheral protrusions extending along the direction of the ends thereof, and the peripheral protrusions of the tubular part are pressed onto the V-shaped notch.

[0031] By pressing the peripheral protrusion of the cylindrical part onto the V-shaped notch, the lever force of the peripheral protrusion can be utilized so that the entire cylindrical part can be more stably fixed on the V-shaped notch, thereby improving the shockproof effect.

[0032] The beneficial effects of the anti-vibration fixture for cylindrical parts of the present invention are as follows:

[0033] (1) The anti-vibration fixture for cylindrical parts of the present invention uses a first support block with a first V-shaped notch and a second support block with a second V-shaped notch. The cylindrical part is first positioned by the V-shaped notch, and then a pressure block is used to cooperate with the V-shaped notch to fix the two ends of the cylindrical part on the V-shaped notch. The cylindrical part can be fixed with the smallest area to avoid affecting the processing. At the same time, the cylindrical part is also fixed only to be axially rotatable, avoiding the problem that the movement of the cylindrical workpiece in multiple directions affects the processing.

[0034] (2) The anti-vibration fixture for cylindrical parts of the present invention has a simple overall structure, can stably fix the cylindrical parts in a limited space, has low cost, and will not easily cause the cylindrical parts to roll or fall no matter how the fixture is swung. It has the advantage of a high safety index and is suitable for large-scale production and application. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] It should be understood that although the terms "first", "second", "third", etc. may be used to describe various information in the present invention, such information should not be limited to these terms. These terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0045] Example 1

[0046] At present, some cylindrical parts 8 have features that need to be processed to the same extent around the body. In this regard, the two ends of the cylindrical part 8 will be positioned and a four-axis machine tool will be used for processing. Due to the limitation of assembly space and the need to save costs, the cylindrical part 8 cannot be fixed well, resulting in not only axial rotation but also radial rotation of the cylindrical part 8 during processing. The entire cylindrical part 8 shakes severely, affecting the processing quality.

[0047] In this regard, the flexibility of processing is currently increased by five-axis machining equipment. Although the five-axis machining equipment can solve the problem of radial and axial shaking of parts, its equipment cost is too expensive and is not conducive to large-scale application. At present, the cylindrical part 8 is fixed by making a fixed angle tooling, which guarantees the angle and accuracy of the part to a certain extent. However, when the swing angle of the part is too large, it is not easy to clamp, and the risk factor increases synchronously when the tilt angle is too large. In addition, the universal matching of this kind of tooling is almost zero, and only one set of fixed angle tooling can be made for one part at one angle, which invisibly increases the tooling cost sharply.

[0048] To solve the above technical problems, the anti-vibration fixture for the cylindrical part 8 disclosed in this embodiment is shown in FIG. Figure 1 to Figure 5 , comprising a base 1, a first support block 4, a second support block 5, a first pressing block structure and a second pressing block structure,

[0049] The bottom end of the first support block 4 is fixed on the base 1, and the top end of the first support block 4 is provided with a first V-shaped notch 6.

[0050] The large opening of the first V-shaped notch 6 faces upward, and is used to support the cylindrical part 8 , wherein the first supporting block 4 provides a setting position for the first V-shaped notch 6 .

[0051] The bottom end of the second support block 5 is fixed on the base 1, and the top end of the second support block 5 is provided with a second V-shaped notch 7.

[0052] The second V-shaped notch 7 has a large opening facing upwards, and is used to support the cylindrical part 8 , wherein the second supporting block 5 provides a setting position for the second V-shaped notch 7 .

[0053] The first V-shaped notch 6 and the second V-shaped notch 7 are spaced apart and relatively aligned with each other. The first pressing block structure is pressed on the first V-shaped notch 6, and the second pressing block structure is pressed on the second V-shaped notch 7.

[0054] The first V-shaped notch 6 and the second V-shaped notch 7 are aligned with each other, and the first V-shaped notch 6 and the second V-shaped notch 7 can overlap each other by moving along a straight line, so as to support the cylindrical part 8 on the axis and avoid radial rotation of the cylindrical part 8.

[0055] When positioning the cylindrical part 8 , the two ends of the cylindrical part 8 are respectively mounted on the first V-shaped notch 6 and the second V-shaped notch 7 , and the first pressing block structure and the second pressing block structure extend into the cylindrical part 8 and press the two ends of the cylindrical part 8 .

[0056] When the two ends of the cylindrical part 8 are respectively mounted on the first V-shaped notch 6 and the second V-shaped notch 7, the cylindrical part 8 still cannot be stably mounted on the first support block 4 and the second support block 5, and then a related pressing block structure is arranged above the first V-shaped notch 6 and the second V-shaped notch 7. The pressing block structure will press on the inner wall of the cylindrical part 8 to fix the two ends of the cylindrical part 8.

[0057] This allows the entire cylindrical member 8 to be stably positioned.

[0058] Specifically,

[0059] As the foundation of the whole structure, other components are fixed on it. The bottom ends of the two support blocks are fixed on the base 1. The top of each support block is designed with a V-shaped notch, which is used to support the cylindrical part 8, and the large opening faces upward.

[0060] The tops of the first support block 4 and the second support block 5 are respectively provided with first and second V-shaped notches 7. The two notches are aligned with each other and can be overlapped by linear movement so as to support the cylindrical part 8 on the axis to prevent it from radial rotation.

[0061] The first pressing block structure and the second pressing block structure are respectively arranged on the first and second V-shaped notches 7. These pressing block structures can extend into the cylindrical part 8 and press against both ends thereof to fix the cylindrical part 8.

[0062] When the cylindrical part 8 is positioned, its two ends are respectively placed on the first and second V-shaped notches 7. Then, the pressing block structure extends into the cylindrical part 8 and presses against its two ends to achieve fixation.

[0063] If the cylindrical part 8 is still unstable only by being supported by the V-notch, a pressure block structure can be set above the V-notch and pressed on the inner wall of the cylindrical part 8 to further fix the two ends of the cylindrical part 8 to ensure that the entire cylindrical part 8 can be stably positioned. Features that cannot be processed due to rotation angles are changed into spatial axial rotation angles through tooling to process features, and when designing the tooling, the accuracy of the previous process, the seismic resistance of this process, and the processing stability of this process will be guaranteed during the processing to ensure part accuracy, dimensional stability, and shock-proof technology.

[0064] The V-shaped notch effectively disperses the load, making the support more stable, reducing vibration and shaking, and improving stability; the contact area with the workpiece is reasonable, reducing bumps and wear; while providing reliability, the production cost is relatively low, and it has a high cost-effectiveness.

[0065] This embodiment changes the radial rotation, increases shockproof, and ensures the stability of the result-oriented tooling. It greatly improves the processing convenience, is not bound by expensive equipment, and reduces the investment cost of equipment; improves the versatility of tooling and optimizes the time wasted by frequent tooling changes for the same type of parts, and achieves efficient, high-frequency and convenient replacement of the same or even different parts, greatly improving work efficiency and reducing the invisible time cost loss; at the same time, it avoids the troubles caused by deformation and vibration of the processed parts when processing various feature surfaces, inner holes, flattening, and transition grooves.

[0066] In this embodiment, the V-shaped angle of the V-shaped opening is greater than 90°.

[0067] When the included angle of the V-shaped opening is greater than 90°, the contact area between the tubular part 8 and the V-shaped opening can be effectively increased, thereby effectively improving the stability of the support.

[0068] When the angle of the V-shaped opening is greater than 90°, it means that the two sides of the V-shaped notch are closer to vertical, thereby increasing the contact area with the cylindrical part 8. This design can provide greater friction, which helps prevent the cylindrical part 8 from sliding or rolling on the support block. Due to the increase in contact area, the friction between the cylindrical part 8 and the V-shaped notch also increases, which helps to improve the stability of the support. During machining or assembly, this stability is crucial to maintaining the precise position of the cylindrical part 8. The design with a V-shaped angle greater than 90° also helps prevent the cylindrical part 8 from rotating radially. This is because the larger angle makes the two ends of the cylindrical part 8 fit more tightly in the V-shaped notch, reducing the possibility of rotation caused by external forces. By adjusting the angle of the V-shaped notch, this design can adapt to cylindrical parts 8 of different sizes. For cylindrical parts 8 with larger diameters, a larger angle can provide better support; while for cylindrical parts 8 with smaller diameters, the angle can be appropriately reduced to adapt to their size.

[0069] The design with a V-shaped angle greater than 90° also means that the pressure block structure needs to be optimized accordingly to ensure that they can effectively extend into the interior of the cylindrical part 8 and provide sufficient pressure to fix the two ends of the cylindrical part 8.

[0070] In this embodiment, the first pressing block structure and / or the second pressing block structure comprises a vertical rod 9 , a pressing plate 10 is provided on the top of the vertical rod 9 , and the pressing plate 10 extends into the tubular part 8 and presses against the inner wall surface of the end of the tubular part 8 .

[0071] The vertical rod 9 is used to support the pressing plate 10 . The supporting effect of the vertical rod 9 enables the pressing plate 10 to be pressed on both ends of the cylindrical part 8 better.

[0072] In this embodiment, the vertical rod 9 is a telescopic rod of a cylinder.

[0073] By using the air cylinder, the pressing plate 10 can be better controlled to press on the inner wall surfaces at both ends of the cylindrical part 8, or the pressing plate 10 can be kept away from the inner wall surfaces at both ends of the cylindrical part 8, so as to control the fixing or loosening of the cylindrical part 8.

[0074] The hydraulic pressing plate 10 can be used to replace the pressing, reduce factors such as poor fitting, make the surface fitting higher and more accurate, and improve the product quality, dimensional stability and convenience of clamping.

[0075] The base 1 is also provided with a support seat 11 , and the support seat 11 supports the middle outer wall surface of the cylindrical part 8 .

[0076] The support seat 11 can better support the middle outer wall surface of the tubular part 8, avoiding the problem of the middle part of the tubular part 8 sagging due to excessive weight, improving the stability of the entire tubular part 8, and preventing the tubular part 8 from deforming.

[0077] In this embodiment, the support seat 11 includes a curved panel 12 , and the curved panel 12 is attached to the middle outer wall surface of the cylindrical part 8 .

[0078] The curved panel 12 can be well fitted with the outer wall surface of the cylindrical part 8, thereby improving the support stability.

[0079] In this embodiment, the arcuate concave surface of the arc panel 12 fits with the middle outer wall surface of the tubular part 8 , and the arched surface of the arc panel 12 is fixed on a positioning plate 13 , and the positioning plate 13 is arranged on the base 1 .

[0080] To further improve the fixing stability of the curved panel 12 , the curved concave surface of the curved panel 12 is directed toward the outer wall of the tubular part 8 , and then the arched surface of the curved panel 12 is set on a positioning plate 13 , which is used to position the entire curved panel 12 .

[0081] In this embodiment, the base 1 includes a base plate 2 , and slide rails 15 are provided on both ends of the base plate 2 . A slide plate 3 slides on the slide rails 15 , and the pressing block structure and the supporting block are fixed on the slide plate 3 .

[0082] A slide rail 15 is provided on the base plate 2 to facilitate setting the slide plate 3 on the slide rail 15. The pressing block structure and the supporting block arranged on the slide plate 3 can be displaced along with the movement of the slide plate 3 to adapt to different cylindrical parts 8 or to further move the entire cylindrical part 8.

[0083] In this embodiment, two ends of the positioning plate 13 are respectively fixed to the slide plate 3 on two end sides of the base plate 2 .

[0084] The positioning plate 13 is also positioned on the slide plate 3 so that it can move with the sliding movement, thereby supporting the middle position of the cylindrical part 8 in real time.

[0085] The curved panel 12 is fitted to the middle outer wall of the cylindrical part 8, and the support stability is improved by better fitting with the outer surface of the cylindrical part 8. The curved panel 12 has a curved concave surface and an arched surface, the curved concave surface is fitted with the middle outer wall of the cylindrical part 8, and the arched surface is fixed on the positioning plate 13.

[0086] The positioning plate 13 is used to position the entire curved panel 12 to ensure the stability of the curved panel 12. The two ends of the positioning plate 13 are respectively fixed to the slide plates 3 on the two end sides of the base plate 2. The base 1 includes a base plate 2, and slide rails 15 are provided on the two end sides of the base plate 2.

[0087] A slide plate 3 slides on the slide rail 15 , and the pressing block structure and the supporting block are both fixed on the slide plate 3 .

[0088] By providing a slide rail 15 on the base plate 2 , the slide plate 3 can move on the slide rail 15 , so that the pressing block structure and the supporting block can be displaced with the movement of the slide plate 3 to adapt to the tubular parts 8 of different sizes or to further adjust the tubular parts 8 .

[0089] The positioning plate 13 is also positioned on the slide plate 3 , so that the positioning plate 13 can move along with the movement of the slide plate 3 , thereby achieving real-time support for the middle position of the cylindrical part 8 .

[0090] The introduction of the curved panel 12 and the sliding mechanism not only improves the support stability of the cylindrical part 8, but also increases the adaptability to cylindrical parts 8 of different sizes. The curved panel 12 fits better with the outer surface of the cylindrical part 8, reducing the possibility of slippage, while the sliding mechanism allows the precise position adjustment of the cylindrical part 8 to meet different processing or assembly requirements. This design may be very useful in mechanical processing, assembly lines or automated equipment because it can improve the flexibility and efficiency of operations.

[0091] In this embodiment, the two ends of the tubular part 8 are provided with peripheral protrusions 14 extending along the end direction thereof, and the peripheral protrusions 14 of the tubular part 8 are pressed onto the V-shaped notch.

[0092] By pressing the peripheral protrusion 14 of the tubular part 8 onto the V-shaped notch, the lever force of the peripheral protrusion 14 can be utilized so that the entire tubular part 8 can be more stably fixed on the V-shaped notch, thereby improving the shockproof effect.

[0093] The two ends of the cylindrical part 8 are provided with peripheral protrusions 14 extending along the end direction thereof, which are part of the cylindrical part 8 and are used to cooperate with the V-shaped notch. The peripheral protrusions 14 of the cylindrical part 8 are pressed on the V-shaped notch, and this design enables the cylindrical part 8 to be fixed more tightly in the V-shaped notch.

[0094] By pressing the peripheral projection 14 onto the V-shaped notch, the leverage of the projection can be utilized. This leverage can increase the stability of the tubular part 8 in the V-shaped notch because the projection can provide additional support when subjected to external forces.

[0095] Improve shockproof effect:

[0096] By utilizing the lever force of the peripheral protrusion 14, the entire tubular part 8 can be more stably fixed on the V-shaped notch, which helps to reduce the impact of vibration on the position of the tubular part 8, thereby improving the shockproof effect of the overall structure.

[0097] The cooperation between the peripheral protrusion 14 of the tubular part 8 and the V-shaped notch is an effective method to improve the fixing stability and shockproof effect of the tubular part 8, which is crucial to ensure the accuracy and reliability during machining and assembly.

[0098] The V-notch of the shockproof fixture of the cylindrical part 8 changes the radial rotation into axial rotation (that is, under the positioning of the V-notch, only axial rotation is retained), thereby controlling the risk of rolling of the workpiece and preventing the parts from shock and deformation. Since the middle contact plane area is small, bolts are used for fastening and the height difference is adjusted to make the processed surface fit to the fixture plate. The fitting surface has high precision and simple clamping, which effectively improves the dimensional stability and convenience of the parts. In addition, the shock-resistant effect is good during the processing, the operation is stable, and the work efficiency is high.

[0099] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The main components for achieving efficient and stable clamping of the product include: a left V-block and a right V-block for supporting and positioning the workpiece, ensuring the position and posture of the workpiece clamping, ensuring stability, facilitating clamping operations, and reducing vibration and deformation of parts during processing.

[0100] The double V-block can provide higher guiding accuracy to ensure the accurate position of the workpiece; good stability and effective load dispersion make the support more stable, reduce vibration and shaking, and improve stability; the contact area with the workpiece is reasonable to reduce bumps and wear; while providing reliability, the production cost is relatively low and it has a high cost performance.

[0101] It is convenient to adjust the processing of other parts of the same type, and is suitable for places with high requirements for batch stability. In addition, this positioning method can also be equally applicable to the detection and positioning of similar parts.

[0102] Example 2

[0103] Place the two ends of the cylindrical part 8 on the first V-shaped notch 6 and the second V-shaped notch 7 respectively, then press the pressing block structure on the inner wall surfaces at both ends of the cylindrical part 8 respectively, and then place the entire fixture in horizontal processing. Since the fixture only clamps about 5% of the area of ​​the cylindrical part 8, the machine tool can flexibly process various parts without the use of a multi-axis machine tool, thereby greatly improving production efficiency.

[0104] First, the two ends of the cylindrical part 8 are respectively placed on the first V-shaped notch 6 and the second V-shaped notch 7. This arrangement ensures the stability of the cylindrical part 8 at two supporting points.

[0105] Next, the pressing block structure is pressed respectively onto the inner wall surfaces at both ends of the cylindrical part 8. This further fixes the cylindrical part 8 to prevent it from moving or rotating during the processing.

[0106] The entire jig is placed in a horizontal machining center together with the cylindrical part 8. This arrangement allows the machine tool to process the cylindrical part 8.

[0107] The fixture only clamps about 5% of the area of ​​the cylindrical part 8. This design reduces the coverage of the cylindrical part 8, so that the machine tool can flexibly process various parts of the cylindrical part 8.

[0108] Since the design of the fixture allows machining without the use of multi-axis machine tools, this simplifies the machining process, reduces equipment requirements, and thus improves production efficiency.

[0109] This fixture design provides greater flexibility and economy because it allows complex machining tasks to be completed on single- or dual-axis machines, reducing reliance on expensive multi-axis machines.

[0110] By precisely controlling the position and fixation of the cylindrical part 8, the fixture helps to improve the processing accuracy and ensure that the processed parts meet the design specifications.

[0111] This kind of fixture is suitable for processing various cylindrical parts 8, has wide applicability, and can be used in different production environments and processing requirements.

[0112] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps described in these embodiments do not limit the scope of the present application. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0113] In the description of the present application, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present application; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0114] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0115] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.

[0116] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
