Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a grinding wheel angle dressing device. Background Technology

[0002] In the mold processing field, grinding wheel angle dressing is a crucial process for ensuring the machining accuracy of precision parts such as mold inserts. Its dressing efficiency and precision directly affect product quality and production efficiency. Currently, the industry commonly uses two main grinding wheel angle dressing technologies: First, existing grinding wheel angle dressing devices use a screw-type fine-tuning angle table. When adjusting the dressing angle, the target angle needs to be set manually by calculating the shim combination. Second, the dresser adjusts the angle by sliding a wedge block. For example, existing technologies such as the "Precision Angle Adjustment Grinding Wheel Dresser" disclosed in JP2018153770A also adjust the angle by sliding a wedge block; the angle determination in this adjustment method depends on the reading of the vernier scale.

[0003] The two angle adjustment methods mentioned above are not only cumbersome to operate, but also have low adjustment accuracy, making it difficult to meet the requirements of high-precision mold processing.

[0004] Therefore, existing grinding wheel angle dressers need to be improved to overcome the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the problems existing in related technologies, the purpose of this utility model is to provide a grinding wheel angle dresser that can adjust the dressing angle of the grinding wheel through different indexing holes, thereby improving the efficiency of angle adjustment and ensuring the accuracy of angle adjustment.

[0006] A grinding wheel angle dressing device includes a base, on which a plurality of first indexing holes are provided. The plurality of first indexing holes are linearly distributed such that the line connecting the center of each first indexing hole and the bottom edge of the base is set at a preset angle.

[0007] An adjustment seat is hinged to the base, and the adjustment seat is provided with a plurality of second indexing holes corresponding to the first indexing hole. A detachable pin is provided between the second indexing hole and the first indexing hole.

[0008] The adjusting seat is provided with a sliding seat, which is slidably mounted on the adjusting seat, and a trimming tool is provided on the sliding seat.

[0009] The preset angle of the first indexing hole of this angle dresser can be set according to actual production needs. After the angle is designed, when the angle needs to be adjusted during use, first rotate the adjusting seat to the corresponding angle mark so that the first and second indexing holes of the target angle are aligned; then insert the pin into the first and second indexing holes to lock them, completing the angle locking. Then move the sliding seat to drive the dressing tool to grind the grinding wheel, repeating the above grinding process until the grinding wheel reaches the preset angle. This grinding wheel angle dresser uses the quick alignment and positioning of the preset indexing hole and the pin, eliminating the need for calculation or reading during angle adjustment, thus effectively improving angle adjustment efficiency, reducing angle adjustment errors, ensuring machining accuracy, and improving product machining quality.

[0010] In a preferred embodiment of this utility model, the base is provided with a mounting groove, and the adjustment seat is disposed in the mounting groove;

[0011] Along the length of the mounting groove, one end of the adjusting seat is hinged to the base via a rotating shaft.

[0012] In a preferred embodiment of this invention, the first indexing hole penetrates the opposite side walls of the mounting groove along the width direction of the mounting groove.

[0013] The cross-sectional shape of the first indexing hole is circular, elliptical, or polygonal.

[0014] The adjustment seat is embedded in the mounting slot of the base and is hinged by a rotating shaft. Compared with the traditional external connection structure, this can reduce the overall height of the dresser, reduce the lateral space occupied, better fit the compact working environment of small grinding machines, and improve the flexibility of equipment layout.

[0015] The mounting slot can also provide some protection for the adjusting seat, reducing the direct corrosion of the adjusting seat by wear debris and coolant, thereby extending the service life of the entire equipment.

[0016] In a preferred embodiment of this invention, an angle identifier is provided on one side of each of the first indexing holes, and the angle identifier is provided on the side wall of the base.

[0017] The angle markers are directly machined onto the side wall of the base, eliminating the need for additional marking components and simplifying the overall structure. At the same time, the CNC engraving process is compatible with the base machining process, without increasing additional production costs, thus balancing functionality and economy.

[0018] The angle identifier corresponds one-to-one with the position of the first graduation hole, and the font is clear and the marking is intuitive, avoiding the complexity of traditional vernier readings that require estimation or shim combination that requires conversion, and also reducing the probability of errors in subsequent operation.

[0019] In a preferred embodiment of this invention, the angle identifier is coated with a fluorescent layer.

[0020] The fluorescent filler angle markers remain clearly visible even in environments with splashing grinding machine coolant and insufficient light, solving the problem of traditional engravings being difficult to identify in dark environments, reducing the risk of incorrect angle selection due to visual blur, and adapting to complex processing scenarios.

[0021] In a preferred embodiment of this utility model, a guide bar is provided on the top of the adjusting seat, and the length direction of the guide bar is arranged along the length direction of the adjusting seat;

[0022] The bottom of the sliding seat is provided with a sliding groove, and the guide bar is adapted to the sliding groove.

[0023] During use, the sliding seat is pushed along the length of the guide bar, and the slide groove slides smoothly along the guide bar, driving the dressing tool to grind the grinding wheel at the set depth of cut; the reciprocating feed continues until the grinding wheel reaches the preset angle, and the sliding seat does not jam or deviate throughout the entire process.

[0024] The guide bar has a trapezoidal cross-section. The trapezoidal fitting structure between the guide bar and the slide groove can increase the contact area, reduce the fitting clearance, improve the repeatability of positioning during sliding, and avoid the grinding wheel dressing angle error caused by feed offset.

[0025] In a preferred embodiment of this invention, anti-slip components are provided on both opposite side walls of the sliding seat, and the anti-slip components protrude outward from the side walls of the sliding seat.

[0026] Specifically, anti-slip components are provided on both sides of the sliding seat (both sides along the feed direction); the anti-slip components are made of nitrile rubber and are fixed to the side wall of the sliding seat by epoxy resin adhesive. The surface of the anti-slip components is processed with transverse serrated texture to enhance hand friction.

[0027] The protruding height and texture design of the anti-slip parts are adapted to the natural grip posture of an adult's thumb and forefinger. When the operator pinches the anti-slip parts on both sides, the fingertips fit against the serrated texture, and the protruding thickness prevents the fingers from directly contacting the metal sidewall of the sliding seat, thus preventing slippage and effectively ensuring the straightness of the grinding trajectory.

[0028] In a preferred embodiment of this invention, the sliding seat is provided with a tool mounting position; the trimming tool includes a cutting head and a locking washer; the cutting head is disposed in the tool mounting position and its top protrudes from the top of the sliding seat, and the locking washer is disposed at the bottom of the tool mounting position and is fixedly connected to the sliding seat.

[0029] Specifically, the locking washer is rigidly fixed by screws, creating an axial preload on the cutter head to counteract high-frequency vibrations during regrinding. The detachable structure of "locking washer + screw" allows for cutter head replacement without special tools, saving time per replacement.

[0030] In a preferred embodiment of this invention, the bottom of the base is provided with a plurality of magnetic suction components, which are arranged along the length of the base at the bottom of the base.

[0031] Specifically, in this embodiment, during use, the base is placed on the worktable of the grinding machine at the position to be fixed, ensuring that the magnetic component is in contact with the iron surface of the worktable; the base is gently pushed to adjust to the approximate working position, and the magnetic component automatically adheres to the table surface to complete the fixation; after confirming that the angle indexing hole is in the correct relative position with the grinding wheel, the grinding process can be carried out. After the grinding is completed, applying a large pulling force can separate the base from the worktable, facilitating transfer or repositioning.

[0032] The base uses a magnetic attachment at the bottom to create an attraction force with the grinding machine table, which can resist the axial thrust generated during the grinding process, ensuring that the base does not shift and thus guaranteeing machining accuracy.

[0033] In a preferred embodiment of this utility model, the base is provided with a snap-fit ​​component, which includes an elastic element and a snap-fit ​​head. The elastic element is disposed on the side wall of the first indexing hole, and the snap-fit ​​head is disposed at one end of the elastic element and is exposed in the first indexing hole.

[0034] The pin has a slot in the middle, and the locking head is adapted to the slot.

[0035] In this embodiment, when the pin is inserted into the first indexing hole (after being aligned with the second indexing hole of the adjusting seat): the outer wall of the pin presses against the locking head, compressing the elastic element; when the pin is inserted deep into the slot and corresponds to the locking member, the elastic element resets, pushing the locking head into the slot, forming a "click" sound feedback, and realizing mechanical interlocking; when unlocking, the pin is rotated, the slot presses against the locking head, compressing the elastic element again, the locking head disengages from the slot, and the pin can be easily pulled out.

[0036] The arc-shaped fitting structure of the chuck head and the chuck slot forms a "geometric self-locking" mechanism. Combined with the preload of the elastic element, this eliminates the gap between the pin and the indexing hole, thereby improving machining accuracy.

[0037] The beneficial effects of this utility model are as follows:

[0038] This utility model provides a grinding wheel angle dresser, which includes a base and an adjusting seat hinged to the base. The base has multiple first indexing holes linearly distributed, such that the line connecting the center of each first indexing hole to the bottom edge of the base forms a preset angle. The adjusting seat has multiple second indexing holes corresponding to the first indexing holes, with a detachable pin between each second indexing hole and a first indexing hole. A sliding seat is provided on the adjusting seat, and a dressing tool is mounted on the sliding seat. In practical applications, the preset angle of the first indexing holes can be designed according to the grinding wheel angle required for different products, such as mold inserts. This allows for flexible selection of the corresponding indexing hole to adjust the grinding wheel dressing angle according to different product models during subsequent adjustments. To adjust the angle, first rotate the adjusting seat to the corresponding angle mark, aligning the first and second indexing holes at the target angle; then insert the pin into the first and second indexing holes to lock them in place, thus locking the angle. Then, the sliding seat is moved, driving the dressing tool to dredge the grinding wheel. This dressing process is repeated until the grinding wheel reaches the preset angle. This grinding wheel angle dresser uses a preset indexing hole and a pin for quick alignment and positioning. No calculation or reading is required during angle adjustment, which can effectively improve the efficiency of angle adjustment, reduce angle adjustment errors, ensure machining accuracy, and improve the quality of product processing.

[0051] Preferred embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention will be thorough and complete, and will fully convey the scope of the present invention to those skilled in the art.

[0052] In the mold processing field, grinding wheel angle dressing is a crucial process for ensuring the machining accuracy of precision parts such as mold inserts. Its dressing efficiency and precision directly affect product quality and production efficiency. Currently, the industry commonly uses two main grinding wheel angle dressing technologies: First, existing grinding wheel angle dressing devices use a screw-type fine-tuning angle table. When adjusting the dressing angle, the target angle needs to be set manually by calculating the shim combination. Second, the dresser adjusts the angle by sliding a wedge block. For example, existing technologies such as the "Precision Angle Adjustment Grinding Wheel Dresser" disclosed in JP2018153770A also adjust the angle by sliding a wedge block; the angle determination in this adjustment method depends on the reading of the vernier scale.

[0053] The two angle adjustment methods mentioned above are not only cumbersome to operate, but also have low adjustment accuracy, making it difficult to meet the requirements of high-precision mold processing.

[0054] Based on this, this application provides a grinding wheel angle dressing tool.

[0055] Example 1

[0056] like Figures 1-10As shown, this embodiment provides a grinding wheel angle dressing device, including a base 1. The base 1 is provided with a plurality of first indexing holes 11. The plurality of first indexing holes 11 are linearly distributed, such that the line connecting the center of each first indexing hole 11 and the bottom edge of the base 1 is set at a preset angle.

[0057] An adjustment seat 2 is hinged to the base 1. The adjustment seat 2 is provided with a plurality of second indexing holes 22 corresponding to the first indexing hole 11. A detachable pin 5 is provided between the second indexing hole 22 and the first indexing hole 11.

[0058] The adjusting seat 2 is provided with a sliding seat 3, which is slidably disposed on the adjusting seat 2, and a trimming tool 4 is provided on the sliding seat 3.

[0059] Specifically, in this embodiment, the base 1 is provided with a mounting groove, and the adjustment seat 2 is disposed in the mounting groove;

[0060] Along the length of the mounting groove, one end of the adjusting seat 2 is hinged to the base 1 via a rotating shaft 21. The groove wall of the mounting groove is precision ground, and one end of the mounting groove (near the edge of the base 1) is provided with a hole for the rotating shaft 21 for mounting the rotating shaft 21. By hinged to the base 1 via the rotating shaft 21, the adjusting seat 2 can rotate around the rotating shaft 21 within the mounting groove; specifically, the rotation angle range is 0.5°-5°.

[0061] More specifically, the base 1 has 10 first indexing holes 11 machined along a linear trajectory on its side, each first indexing hole 11 having a diameter of 3mm. The angular spacing between adjacent first indexing holes 11 is 0.5°, covering 10 preset angles of 0.5°, 1°, 1.5°...5°. The corresponding angle value is marked next to each first indexing hole 11 using CNC engraving. The adjusting seat 2 has 10 second indexing holes 22 (3mm in diameter, H7 grade) machined on its side, corresponding one-to-one with the 10 first indexing holes 11 (corresponding to 0.5° incremental angles) on the side wall of the mounting groove of the base 1. The adjusting seat 2 is also equipped with elastic positioning components (pins, springs, hardened tungsten steel balls) for engaging with the first indexing holes 11 to achieve angle locking.

[0062] The preset angle of the first indexing hole 11 of this angle dresser can be set according to actual production needs. After the angle is designed, when the angle needs to be adjusted during use, first rotate the adjusting seat 2 to the corresponding angle mark so that the first indexing hole 11 and the second indexing hole 22 of the target angle are aligned; then insert the pin 5 into the first indexing hole 11 and the second indexing hole 22 to lock them, completing the angle locking. Then move the sliding seat 3 to drive the dressing tool 4 to grind the grinding wheel, repeating the above grinding process until the grinding wheel reaches the preset angle. This grinding wheel angle dresser uses the preset indexing hole and the pin 5 for quick alignment and positioning, eliminating the need for calculation or reading during angle adjustment, thereby effectively improving the angle adjustment efficiency, reducing angle adjustment errors, ensuring machining accuracy, and improving product machining quality.

[0063] Example 2

[0064] This embodiment is an improvement on embodiment 1.

[0065] like Figures 1-10 As shown, in this embodiment, along the width direction of the mounting groove, the first indexing hole 11 penetrates the opposite side walls of the mounting groove;

[0066] The cross-sectional shape of the first indexing hole 11 is circular, elliptical, or polygonal.

[0067] The adjustment seat 2 is embedded in the mounting slot of the base 1 and is hinged by the rotating shaft 21. Compared with the traditional external connection structure, this can reduce the overall height of the dresser, reduce the lateral space occupied, better adapt to the compact working environment of small grinding machines, and improve the flexibility of equipment layout.

[0068] The mounting slot can also provide some protection for the adjusting seat 2, reducing the direct corrosion of the adjusting seat 2 by wear debris and coolant, thereby extending the service life of the entire equipment.

[0069] In addition, the fitting design of the adjustment seat 2 and the mounting slot avoids exposed rotating parts, reducing the risk of operators' hands coming into contact with moving parts; at the same time, the side wall of the mounting slot can serve as a visual reference for angle adjustment, further reducing the rate of operational errors.

[0070] Example 3

[0071] This embodiment is an improvement on embodiment 2.

[0072] like Figures 1-10 As shown, in this embodiment, an angle identifier 12 is provided on one side of the first indexing hole 11, and the angle identifier 12 is provided on the side wall of the base 1.

[0073] Angle identifier 12 is directly machined onto the side wall of base 1, eliminating the need for additional marking components and simplifying the overall structure. At the same time, the CNC engraving process is compatible with the processing flow of base 1, without increasing additional production costs, thus balancing functionality and economy.

[0074] The angle identifier 12 corresponds one-to-one with the position of the first graduation hole 11, and the font is clear and the marking is intuitive, avoiding the complexity of traditional vernier reading that requires estimation or shim combination that requires conversion, and can also reduce the probability of errors in subsequent operation.

[0075] In this embodiment, the angle identifier 12 is coated with a fluorescent layer.

[0076] More specifically,

[0077] The angle identifier 12 is processed by CNC engraving technology, with a font height of 3mm and a depth of 0.5mm. The content is the preset angle value corresponding to the first indexing hole 11 (such as "0.5°", "1°"... "5°").

[0078] In this embodiment, the lettering groove is filled with a fluorescent agent (such as strontium aluminate phosphor) to form a fluorescent layer, which can emit continuous fluorescence in a dimly lit grinding environment, ensuring that the operator can quickly identify the angle;

[0079] The angle identifier 12 and the center of the corresponding first indexing hole 11 are on the same horizontal line with a spacing of 5mm to avoid recognition errors caused by visual offset. The angle identifier 12 filled with fluorescent agent can still be clearly displayed in environments with splashing grinding machine coolant and insufficient light, solving the problem of traditional engraving being difficult to identify in dark environments, reducing the risk of incorrect angle selection due to visual blur, and adapting to complex processing scenarios.

[0080] Example 4

[0081] This embodiment is an improvement on embodiment 1.

[0082] like Figures 1-10 As shown, in this embodiment, a guide bar 23 is provided on the top of the adjustment seat 2, and the length direction of the guide bar 23 is arranged along the length direction of the adjustment seat 2;

[0083] The bottom of the sliding seat 3 is provided with a sliding groove 32, and the guide bar 23 is adapted to the sliding groove 32.

[0084] During use, the sliding seat 3 is pushed along the length of the guide bar 23, and the slide groove 32 slides smoothly along the guide bar 23, driving the dressing tool 4 to grind the grinding wheel at the set depth of cut; the reciprocating feed continues until the grinding wheel reaches the preset angle, and the sliding seat 3 does not jam or deviate throughout the process.

[0085] The cross-section of the guide bar 23 is trapezoidal. The trapezoidal fitting structure between the guide bar 23 and the slide groove 32 can increase the contact area, reduce the fitting gap, improve the repeatability of positioning during sliding, and avoid the grinding wheel dressing angle error caused by feed offset.

[0086] Specifically, the cross-sectional shape of the guide bar 23 can be dovetail-shaped or trapezoidal, and the width on the side closer to the adjusting seat 2 is smaller than the width on the side farther from the adjusting seat 2. This allows the guide bar 23 to lock the sliding seat 3. That is, the trapezoidal structure of the guide bar 23 and the slide groove 32 forms a "geometric self-locking" mechanism—the inner wall of the slide groove 32 fits tightly against the outer wall of the guide bar 23, which can counteract the lateral force generated during the trimming process.

[0087] Furthermore, in this embodiment, anti-slip components 31 are provided on both opposite side walls of the sliding seat 3, and the anti-slip components 31 protrude outward from the side walls of the sliding seat 3.

[0088] In practical applications, the sliding seat 3 is made of S136 hardened steel plate, and the bottom is provided with a groove 32 that matches the guide strip 23 of the adjusting seat 2. Anti-slip parts 31 are provided on both sides of the sliding seat 3 (both sides along the feed direction); the anti-slip parts 31 are made of nitrile rubber and are fixed to the side wall of the sliding seat 3 by epoxy resin adhesive. The surface of the anti-slip parts 31 is machined with transverse serrated texture to enhance the friction of the hand.

[0089] In this embodiment, after the angle is locked (the adjusting seat 2 and the base 1 are positioned through the indexing hole and the pin 5): the operator pinches the anti-slip parts 31 on both sides of the sliding seat 3 with his thumb and forefinger respectively; pushes or pulls the sliding seat 3 along the length of the guide strip 23 of the adjusting seat 2, and controls the feed speed stably by the friction of the texture of the anti-slip parts 31; the dressing tool 4 feeds with the sliding seat 3 and grinds the grinding wheel with a preset depth of cut (0.02mm / cut) until the preset angle is reached.

[0090] The protruding height and texture design of the anti-slip part 31 are adapted to the natural grip posture of an adult's thumb and forefinger. When the operator pinches the anti-slip parts 31 on both sides, the fingertips fit the serrated texture, and the protruding thickness avoids direct contact between the fingers and the metal sidewall of the sliding seat 3, preventing slippage and thus effectively ensuring the straightness of the grinding trajectory.

[0091] Example 5

[0092] This embodiment is an improvement on embodiment 1.

[0093] like Figures 1-10As shown, in this embodiment, the sliding seat 3 is provided with a tool mounting position; the trimming tool 4 includes a tool head 42 and a locking washer 41; the tool head 42 is disposed in the tool mounting position and its top protrudes from the top of the sliding seat 3, and the locking washer 41 is disposed at the bottom of the tool mounting position and is fixedly connected to the sliding seat 3.

[0094] In practical applications, the tool mounting position machined at the top center of the slide seat 3 has a stepped through-hole structure: the upper through-hole has a diameter of Φ5mm and a depth of 8mm, which is used to accommodate the cutting head 42 of the dressing tool 4, ensuring that the top of the cutting head 42 is exposed on the top of the slide seat 3 for easy contact with the grinding wheel for grinding; the lower through-hole has a diameter of Φ8mm and a depth of 4mm, forming a stepped surface, which is used to place the locking shim 41 and provide an installation reference; the inner wall of the mounting position is precision ground to reduce perpendicularity error and ensure that the axis of the cutting head 42 is consistent with the feed direction of the slide seat 3 after installation.

[0095] The locking washer 41 is rigidly fixed by screws, forming an axial preload on the cutter head 42, which can counteract high-frequency vibrations during regrinding. The detachable structure of "locking washer 41 + screw" allows the cutter head 42 to be replaced without special tools, saving time per replacement.

[0096] Example 6

[0097] This embodiment is an improvement on embodiment 1.

[0098] like Figures 1-10 As shown, in this embodiment, the bottom of the base 1 is provided with multiple magnetic suction components 13, which are arranged along the length direction of the base 1 at the bottom of the base 1.

[0099] Specifically, in this embodiment, the magnetic component 13 can be fixed to the mounting groove (5mm deep) at the bottom of the base 1 by epoxy resin adhesive, with its top surface flush with the bottom surface of the base 1, to ensure the stability of the base 1 when it is placed.

[0100] During use, place the base 1 on the worktable of the grinding machine to be fixed, ensuring that the magnetic suction component 13 is in contact with the iron surface of the worktable; gently push the base 1 to adjust it to the approximate working position, and the magnetic suction component 13 will automatically adhere to the table surface to complete the fixation; after confirming that the angle indexing hole is in the correct relative position with the grinding wheel of the grinding machine, the regrinding process can be carried out. After the regrinding is completed, applying a large pulling force can separate the base 1 from the worktable, making it easy to move or change its position.

[0101] The base 1 is attracted to the grinding machine table by the bottom magnetic suction component 13, which can resist the axial thrust generated during the grinding process and ensure that the base 1 does not shift, thereby ensuring the machining accuracy.

[0102] Example 7

[0103] This embodiment is an improvement on embodiment 1.

[0104] like Figures 1-10 As shown, in this embodiment, the base 1 is provided with a snap-fit ​​member 6, which includes an elastic member 61 and a snap-fit ​​head 62. The elastic member 61 is disposed on the side wall of the first indexing hole 11, and the snap-fit ​​head 62 is disposed at one end of the elastic member 61 and is exposed in the first indexing hole 11.

[0105] The pin 5 has a slot 51 in the middle, and the clip head 62 is adapted to the slot 51.

[0106] In this embodiment, the pin 5 is a cylindrical structure adapted to the first indexing hole 11, with a spherical groove 51 machined along the circumference in the middle. The groove 51 has an arc-shaped cross-section, which matches the shape of the clip head 62; the top of the pin 5 is provided with a handle for easy gripping and insertion / removal.

[0107] When the pin 5 is inserted into the first indexing hole 11 (after being aligned with the second indexing hole 22 of the adjusting seat 2): the outer wall of the pin 5 presses against the locking head 62, compressing the elastic element 61; when the pin 5 is inserted into the slot 51 and corresponds to the position of the locking member 6, the elastic element 61 resets, pushing the locking head 62 into the slot 51, forming a "click" sound feedback, realizing mechanical interlocking; when unlocking, rotate the pin 5, the slot 51 presses against the locking head 62, compressing the elastic element 61 again, the locking head 62 disengages from the slot 51, and the pin 5 can be pulled out smoothly.

[0108] The arc-shaped fitting structure of the chuck 62 and the chuck 51 forms a "geometric self-locking" mechanism. Combined with the pre-tightening force of the elastic element 61, it can eliminate the gap between the pin 5 and the indexing hole, thereby improving the machining accuracy.

[0109] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this application. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0110] In the description of this application, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this application and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this application; the directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0111] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below."
