[0002] The tooling machine platform is the installation basis of various functional modules and electrical source components, including a tooling bottom frame for installing various electrical elements and a tooling support for installing active functional modules, and the tooling support is assembled in subsequent processes based on the tooling bottom frame.

[0003] The tooling bottom frame in the related technical means includes a frame body forming an installation basis, a plurality of outer panels installed on the frame body, and a plurality of electrical installation plates, the frame body is usually composed of a plurality of square tubes or a plurality of aluminum profiles or a plurality of bent sheet metals welded, and then the plurality of outer panels and the plurality of electrical installation plates are sequentially welded and assembled based on the frame body to be integrally arranged.

[0004] When the tooling machine platform is used for assembling medical ultrasonic equipment, the precision of the ultrasonic functional module requires high accuracy of the tooling as a whole. According to the related technical means in the above, the square tube frame body, the aluminum profile frame body, and the strip-shaped sheet metal frame body are all composed of a plurality of butt joints, the structure is relatively complex, and each square tube, each aluminum profile, and each strip-shaped sheet metal need to be welded or assembled when they are butt jointed, thereby there is a problem that the tooling bottom frame process preparation is relatively cumbersome; on the other hand, due to the plurality of butt joints, the machining error accumulates, thereby affecting the overall accuracy of the tooling. SUMMARY

[0005] In order to improve the problem that the tooling bottom frame process welding preparation cannot be facilitated while ensuring the overall accuracy of the tooling in the above related technical means, the present application provides a tooling machine platform and a preparation process thereof.

[0006] In a first aspect, the present application provides a tooling machine platform, which adopts the following technical solution.

[0007] A tooling machine platform includes a tooling bottom frame as a core reference and a tooling support for installing functional modules, the tooling support includes a first side support plate and a second side support plate, the first side support plate and the second side support plate are symmetrically the same in structure and are symmetrically assembled based on the tooling bottom frame;

[0008] The tooling bottom frame is made of sheet metal material and includes an upper operation panel, a vertical electrical panel, a lower bottom sealing panel, and a surface shell, the vertical electrical panel is vertically arranged between the upper operation panel and the lower bottom sealing panel to form a module to be installed, and the surface shell is sleeved on the upper operation panel and abuts against the lower bottom sealing panel to form an installation space for installing various electrical elements;

[0009] The face shell body is open at the bottom and comprises vertically arranged shell vertical edges and horizontally arranged bending abutment edges at the bottom; the upper operating panel has a vertically bent and rivet-fixed pull-back edge that is partially rivet-fixed to the side surface of the face shell body, and the lower bottom sealing panel has a bearing horizontal edge that is partially welded to the bottom surface of the bending abutment edge; the first side support plate is limited and abuts against the pull-back edge with the shell vertical edge as the vertical reference and the bearing horizontal edge as the horizontal reference.

[0010] By adopting the technical scheme, the first side support plate and the second side support plate are symmetrically installed and have symmetric and same structures, and here, only the first side support plate is taken as an example for detailed description. The bearing horizontal edge is partially abutted, so that the non-abutted part of the bearing horizontal edge and the shell vertical edge constitute two installation references of the first side support plate, and the pull-back edge is partially rivet-fixed and serves as the limiting reference surface of the first side support plate, so that even if the pull-back edge has a slight straightness error in the horizontal direction due to the rivet operation, the accuracy of the pull-back edge as the limiting reference surface abutting against the first side support plate is not affected, and the bearing horizontal edge is independent of the pull-back edge, that is, the face shell body, so that the bearing horizontal edge is not affected by the rivet operation, thereby improving the accuracy of the whole tooling machine table based on the same. Under the premise, the welding nodes required in the whole tooling bottom frame are only the relative connection positions of the bending abutment edge and the bearing horizontal edge, so that the welding preparation of the tooling bottom frame is facilitated. In summary, the problem that the tooling cannot be accurately prepared under the premise of ensuring the accuracy of the tooling is solved.

[0011] Optionally, the tooling support further comprises an upper abutment strip and a lower support strip transversely inserted into the first side support plate and the second side support plate, and a cantilever support member for installing a sound-emitting display module is arranged between the upper abutment strip and the lower support strip in the vertical direction.

[0012] The cantilever support member comprises a main installation shell with one side fully open and a reinforcing plate arranged in the main installation shell, the lower support strip abuts against the bottom wall of the main installation shell, the upper abutment strip abuts against the top wall of the main installation shell, and the reinforcing plate abuts against the inner top surface and the two inner side surfaces of the main installation shell.

[0013] By adopting the technical scheme, the lower support strip is transversely inserted into the symmetrically assembled first side support plate and the second side support plate and abuts against the bottom wall of the main installation shell, thereby providing an installation reference for the main installation shell; the upper abutment strip abuts against the top wall of the main installation shell, so that the cantilever support member is not vertically inclined, thereby facilitating high-precision installation of the cantilever support member. The reinforcing plate abuts against the inner top surface and the two inner side surfaces of the main installation shell, thereby stably supporting the main installation shell after being fully opened on one side, and facilitating high-precision and stable installation of the sound-emitting display module.

[0014] Optionally, a support reinforcing edge is arranged on the side of the top surface of the face shell body close to the cantilever support, and the support reinforcing edge is arranged to extend in the vertical direction towards the direction close to the upper abutting strip; and the support reinforcing edge is fixedly arranged in abutment with the lower support strip.

[0015] By adopting the above technical solution, the support reinforcing edge is fixedly arranged with the lower support strip, thereby further improving the stability of the connection between the tool bottom frame and the tool support, so that there is no misalignment deviation between the two.

[0016] Optionally, the upper operation panel and the lower bottom sealing panel are both provided with a plurality of stamping holes.

[0017] By adopting the above technical solution, the plurality of stamping holes are arranged to dissipate heat for a plurality of electrical elements installed in the tool bottom frame, thereby avoiding internal heat accumulation; and the upper operation panel and the lower bottom sealing panel play the role of air conduction and heat dissipation as the installation reference of the face shell body, thereby fully maximizing the functions.

[0018] Secondly, the application provides a preparation process of the tool machine, which is used to prepare the tool machine, and includes the following steps:

[0019] S1. preparing the integrated tool bottom frame;

[0020] S2. synchronously preparing each component in the tool support;

[0021] S3. after the first side plate is installed in place with the horizontal edge extension part as the horizontal reference, the shell vertical edge as the vertical reference, and the back edge extension part as the limiting reference for the side surface, all the connection points in this step are fixed by spot welding;

[0022] S4. after the lower support strip is inserted, the cantilever support is installed, and then the upper abutting strip is installed in abutment with the main installation shell top wall; the second side plate is symmetrically fixed, and all the connection points in this step are fixed by spot welding;

[0023] S5. the remaining components are fixed by spot welding, and after the important reference dimensions are checked by the gauge, they are fixed by welding;

[0024] S6. the welded parts are polished and smoothed, and the outer surface is electroplated;

[0025] S7. all the threaded holes are threaded, and the whole machine is assembled according to the operation requirements.

[0026] By adopting the technical scheme, the first side plate is installed by taking the horizontal edge, the vertical edge of the shell and the pull-riveting backrest edge as the reference, and is preliminarily fixed by spot welding; then the lower support strip, the cantilever support piece and the upper abutting strip are sequentially installed by taking the first side plate as the reference, and are preliminarily fixed by spot welding, and are fixed by welding after checking the gauge, which helps to control the key dimensions and correct them in time. When the production is relatively large, it is impossible to check once for every part, and the process sequence of spot welding, checking the key dimensions and finally welding helps to improve the production efficiency on the premise of ensuring the overall precision of the tooling.

[0027] The preparation steps of the tooling bottom frame in S1 are as follows:

[0028] S11. The sheet metal is bent and formed into an upper operation panel, a vertical electrical panel and a lower bottom sealing panel, and is assembled into an integrated to-be-assembled module, and a face shell is synchronously formed;

[0029] S12. The face shell is sleeved on the integrated to-be-assembled module, the bent abutting edge of the face shell is arranged opposite to the horizontal edge of the lower bottom sealing panel; a same-shaped locking tooling is correspondingly and sequentially arranged in the plurality of waist-shaped holes, and is used for preliminarily fixing the face shell and the to-be-assembled module;

[0030] S13. The pull-riveting is performed at the position where the pull-riveting backrest edge is opposite to the side surface of the face shell, and is used for fixing the face shell and the to-be-assembled module;

[0031] S14. The locking tooling is disassembled, and the assembly welding is performed at the position where the bent abutting edge is opposite to the horizontal edge;

[0032] S15. The node is polished to be smooth;

[0033] S16. The surface of the face shell is planarly shaped.

[0034] By adopting the technical scheme, the face shell is installed by taking the to-be-assembled module as the reference, that is, the bent abutting edge is arranged opposite to the horizontal edge; then the same-shaped locking tooling is used to preliminarily fix the face shell and the to-be-assembled module, so as to facilitate the subsequent pull-riveting fixing; after the pull-riveting fixing, the assembly welding is performed. The hole shape used for arranging the same-shaped locking tooling is waist-shaped, so that the gap error of the pull-riveting reserved hole can be improved, and the problem that the to-be-assembled module and the face shell are dislocated in the pull-riveting process due to the pull-riveting force, thereby affecting the reference precision of the tooling bottom frame. The aluminum profile or square tube is not used in the tooling bottom frame, and the to-be-assembled module itself is used as the support, so that the structural strength of the to-be-assembled module itself is fully utilized, and the installation space in the tooling bottom frame is large.

[0035] In S2, the first side plate in the tooling support needs to be formed into a first stand column shell and a first reinforcing plate respectively, the first reinforcing plate is assembly welded on the cavity of the first stand column shell, and the two side surfaces with the largest area of the first side plate are planarly shaped by punching.

[0036] By adopting the technical scheme, the first reinforcing plate is assembled in the first column shell, so that the first side support plate arranged integrally has high strength. In sheet metal technology, the larger the area, the lower the plane strength and the easier the deformation. The two sides of the first side support plate with large area are normally shaped to maintain high plane precision, thereby facilitating the accuracy of subsequent use as a reference.

[0037] In S2, after the forming main mounting shell and the reinforcing plate are prepared in the cantilever support, the reinforcing plate is buckled into the main mounting shell along one side of the full opening of the main mounting shell;

[0038] Bolts are pre-assembled one by one through the corresponding plurality of reference holes, and spot welding is performed at the side abutment between the main mounting shell and the reinforcing plate, avoiding all pre-holes;

[0039] The vertical reinforcing plate adopts CNC precision machining to pre-drill holes, and performs precision drilling, hole expansion and chamfering operations to form mounting holes;

[0040] Then, the welding is fixed and the welding part is polished.

[0041] By adopting the technical scheme, the reinforcing plate is installed in the main mounting shell with one-side full opening, and pre-assembled with bolts and pre-fixed by spot welding on both sides, so that the two are arranged integrally, which facilitates the precision machining of the pre-holes. In conventional technical means, the required mounting holes are usually machined by CNC drill before the two are fixed for convenience. Compared with the conventional technical means, the adjusted process steps make the mounting holes after precision machining of the two have accurate coaxiality, which facilitates the high-precision installation of the subsequent sound display module.

[0042] In summary, the present application has at least one of the following beneficial technical effects:

[0043] 1. High reference accuracy. After the tooling bottom frame is arranged integrally, the first side support plate uses the reserved part of the horizontal edge as the horizontal reference and the vertical edge of the shell as the vertical reference. After adjusting the position, the back-lap edge is fixed by riveting and is installed in the tooling bottom frame. The horizontal edge and the vertical edge of the shell are completely independent and do not interfere with each other, and they do not need to be riveted. Although the straightness deviation may exist at the connection between the back-lap edge and the inner side of the shell after the riveting operation, the flatness of the back-lap edge as the limiting reference is not affected. In addition, the horizontal edge and the bent abutment edge are provided with a waist-shaped hole. Before riveting, the same shape locking tool is inserted into the waist-shaped hole to pre-fix the face shell and the lower bottom cover panel. Due to the limitation of the waist-shaped hole and the same shape locking tool, the two will not be misaligned. At the same time, after spot welding the first side support plate and the second side support plate, important reference dimensions are checked and corrected in time before welding, so that the tooling machine table in the present application has high reference accuracy.

[0044] 2. The preparation of the fixture base frame is relatively simple. A vertical electrical board is positioned between the upper operating panel and the lower bottom sealing panel, making the pre-assembled module in an "I" shape. The outer shell is fitted over the module, with its bent abutting edge abutting against the horizontal receiving edge. The inner side abuts against part of the riveting back edge for riveting. After riveting, the matching locking fixture is removed, and the connection between the bent abutting edge and the horizontal receiving edge is welded for fixation. Throughout the entire process, the welding point of the fixture base frame is only at the connection between the bent abutting edge and the horizontal receiving edge, unlike fixture base frames made of square tubing, aluminum profiles, or strip sheet metal, which require assembly (or welding) of each piece individually.

[0051] The present application will be further described in detail below with reference to the accompanying drawings.

[0052] This application discloses a tooling machine and its manufacturing process. (Refer to...) Figure 1 First, this application discloses a tooling machine, including a tooling base frame 1 for use as a core reference and a tooling bracket 2 for installing multiple functional modules. The tooling bracket 2 is welded and assembled with the tooling base frame 1 as a reference.

[0053] ReferenceFigure 2 The tooling base frame 1 includes an upper operating panel 11, a vertical electrical board 12, a lower bottom sealing panel 13, and a front housing 14. All four components are formed by bending sheet metal. The vertical electrical board 12 is vertically positioned between the upper operating panel 11 and the lower bottom sealing panel 13 to form an "I"-shaped module to be assembled. The side of the upper operating panel 11 is a riveted back edge 111 that extends inward after two bends. The length of the riveted back edge 111 is less than the Y-axis length of the side of the front housing 14. The lower bottom sealing panel 13 is generally "U"-shaped, and its two horizontally extending sides after bending are horizontal receiving edges 131. The horizontal receiving edges 131 have multiple oblong holes 131A.

[0054] Reference Figure 2 The face shell 14 is U-shaped with three open sides at the bottom. Its bottom side has a bent, horizontally extending, abutting edge 141. This bent abutting edge 141 also has multiple oblong holes 131A, identical in shape to the receiving horizontal edge 131. The length of the bent abutting edge 141 is less than the length of the receiving horizontal edge 131, but their widths are equal. It is worth noting that there are two symmetrically arranged riveted back edge 111, receiving horizontal edge 131, and bent abutting edge 141. Each vertical side of the face shell 14 has two symmetrically arranged vertical shell edges 142. The two vertical shell edges 142 on the same side extend towards each other through two bends.

[0055] Reference Figure 2 The housing 14 is fitted over the "I"-shaped module to be installed, with its inner side abutting against the riveted back edge 111. The bent abutting edge 141 abuts against the top surface of the horizontal edge 131, thus enclosing a mounting space for installing various electrical components. It is worth noting that both the upper operating panel 11 and the lower bottom sealing panel 13 have multiple punched holes 112, allowing them to conduct heat through space while serving as the mounting reference for the housing 14. During the assembly of the tooling base frame 1, no other external reference is required; the upper operating panel 11 and the lower bottom sealing panel 13, serving as heat dissipation surfaces, are themselves self-referenced, facilitating assembly.

[0056] Reference Figure 1 and Figure 3 The tooling bracket 2 includes a first side support plate 21 and a second side support plate 22 with identical symmetrical structures, which are symmetrically installed on the tooling base frame 1. Since the two have the same structure, only the structure of the first side support plate 21 will be described in detail here. The first side support plate 21 includes a first column shell 211 with a single-sided full opening and a first reinforcing plate 212 welded and fixed inside the cavity of the first column shell 211, so that the integrally set first side support plate 21 has high strength.

[0057] The tool support 2 further comprises an upper abutting strip 23 and a lower supporting strip 24 transversely inserted into the first side supporting plate 21 and the second side supporting plate 22, and a cantilever supporting member 25 for mounting the sound-emitting display module is arranged between the upper abutting strip 23 and the lower supporting strip 24 in the vertical direction. The upper abutting strip 23 and the lower supporting strip 24 each have two groups of horizontal insertion blocks 231 symmetrically arranged in the direction away from each other along the X axis, and correspondingly, the first side supporting plate 21 and the second side supporting plate 22 each have a same-shaped insertion slot 213 opened corresponding to the horizontal insertion blocks 231.

[0058] The cantilever supporting member 25 comprises a one-side fully-opened main mounting shell 251 and a reinforcing plate 252 arranged in the main mounting shell 251, and the lower supporting strip 24 abuts against the bottom wall of the main mounting shell 251 and the upper abutting strip 23 abuts against the top wall of the main mounting shell 251, so that the cantilever supporting member 25 is kept horizontal. The reinforcing plate 252 abuts against the inner top surface and the two inner side surfaces of the main mounting shell 251, thereby facilitating high-precision and stable mounting of the sound-emitting display module.

[0059] The reinforcing plate 252 has a plurality of mounting holes (which are precisely machined from pre-machined holes 251A) for mounting the sound-emitting display module, and the reinforcing plate 252 and the main mounting shell 251 each have three reference holes 251B arranged in the same vertical line at the central axis in the length direction. After the cantilever supporting member 25 is fixedly welded to the upper abutting strip 23 and the lower supporting strip 24, the three reference holes 251B are located at the symmetric central axis of the first side supporting plate 21 and the second side supporting plate 22. It is further explained that the cantilever supporting member 25 further comprises a sound box supporting plate 253 fixed to one side of the main mounting shell 251, and the width of the sound box supporting plate 253 is equal to the distance between the inner side surface of the first side supporting plate 21 and the side surface of the main mounting shell 251 close to the first side supporting plate 21.

[0060] It is further explained that the support reinforcing edge 143 is arranged on the top surface of the face shell 14 close to the cantilever supporting member 25 and extends in the vertical direction towards the upper abutting strip 23, and the support reinforcing edge 143 is fixedly welded to the lower supporting strip 24, so that the tool bottom frame 1 and the tool support 2 are stably welded to be integrally arranged without dislocation.

[0061] The embodiment further discloses a preparation process of a tool machine table, which is used for preparing the tool machine table and comprises the following steps.

[0062] S1. Preparing the integrated tool bottom frame 1.

[0063] S2. Simultaneously preparing each component in the tool support 2.

[0064] S3. The first side plate 21 is installed in place with the horizontal edge 131 as the horizontal reference and the shell vertical edge 142 as the vertical reference, and with the pull-riveted backrest edge 111 as the limit reference for the side surface. All connections in this step are fixed by spot welding.

[0065] S4. After inserting the lower support bar 24, install the cantilever support 25, and then install the abutting bar 23 against the top wall of the main installation shell 251. Fix the second side plate 22 symmetrically. All connections in this step are fixed by spot welding.

[0066] S5. Spot weld the remaining parts, check the important reference dimensions, and then add welding to fix.

[0067] S6. Smooth the welded parts and electroplate the outer surface.

[0068] S7. All threaded holes are threaded, and the entire machine is assembled according to the operation requirements.

[0069] The process steps of first spot welding and then checking and finally adding welding to fix help control the key dimensions of the tooling as a whole and correct errors in time to avoid error accumulation. Taking the first side plate 21 as an example, the vertical surface of the pull-riveted backrest edge 111 is used as the limit installation reference for the first side plate 21. Therefore, even if the pull-riveted backrest edge 111 slightly tilts downward or upward due to the tolerance of the pull-riveted reserved hole during the operation process, it does not affect the verticality of the plane. The abutting horizontal edge 131 and the shell vertical edge 142, which are independent of the pull-riveted backrest edge 111, provide horizontal and vertical references for the first side plate 21.

[0070] In step S1, the preparation process of the tooling bottom frame 1 is as follows:

[0071] S11. Form the upper operation panel 11, the vertical electrical panel 12, and the lower bottom sealing panel 13 by sheet metal bending and molding, and lock and assemble them into an integrated to-be-assembled module. Simultaneously, form the face shell 14 by bending;

[0072] S12. Set the face shell 14 on the integrated to-be-assembled module, with the bending abutting edge 141 of the face shell 14 opposite to the abutting horizontal edge 131 of the lower bottom sealing panel 13. Install the same shape locking tooling in the plurality of waist-shaped holes 131A one by one for pre-fixing the face shell 14 and the to-be-assembled module;

[0073] S13. Rivet the pull-riveted backrest edge 111 opposite to the side surface of the face shell 14 for fixing the face shell 14 and the to-be-assembled module;

[0074] S14. Remove the locking tooling and group weld at the opposite connection between the bending abutting edge 141 and the abutting horizontal edge 131.

[0075] S15. Grinding flat, smooth at the welding joint;

[0076] S16. Plane the surface of the shell 14.

[0077] Corresponding threaded holes are drilled in the waist-shaped holes 131A, so that the shell 14 and the I-shaped module cannot be dislocated during the riveting operation. The welding points in the whole tool base frame 1 are only the relative connection between the bent abutting edge 141 and the receiving horizontal edge 131, so the required welding points are less, thereby facilitating the welding preparation of the tool base frame 1. After the tool base frame 1 is integrally welded, part of the riveting backrest edge 111, part of the receiving horizontal edge 131 and the whole shell vertical edge 142 are reserved. The tool base frame 1 is fixed by locking first and then riveting and finally welding, and has high precision, thereby serving as the installation reference of the tool support 2. It is to be noted that in the embodiment of the present application, two waist-shaped holes 131A are arranged on one side, and the corresponding threaded holes are drilled in the waist-shaped holes 131A. The threaded holes are threaded holes with waist-shaped bolt caps, which are different from ordinary bolts. The waist-shaped bolt cap is integrally provided with a limiting cap at the end away from the threaded bolt body, and the diameter of the limiting cap is larger than that of the waist-shaped hole 131A. During the pre-fixing, the waist-shaped bolt cap is limited in the waist-shaped hole 131A, and the limiting cap and the nut limit the waist-shaped bolt cap from both sides, thereby realizing the pre-fixing of the shell 14 and the I-shaped module to be installed.

[0078] The preparation process of the cantilever support 25 in step S2 includes the following steps: after the forming main installation shell 251 and the reinforcing plate 252 are prepared, the reinforcing plate 252 is buckled in the main installation shell 251 along the side of the whole opening of the main installation shell 251; threaded bolts are pre-assembled in the three reference holes 251B one by one, and the main installation shell 251 and the reinforcing plate 252 are fixed by spot welding at the side abutting position, avoiding all pre-made holes 251A; the CNC precision machining pre-made holes 251A are made in the vertical reinforcing plate 252, and the precision holes, the hole expansion and the chamfering operation are performed to form installation holes; then, the installation holes are fixed by welding and the welding position is ground flat. The pre-assembly, spot welding and CNC coaxial precision machining of the pre-made holes 251A make the installation holes after the precision machining have accurate coaxiality. It is to be noted that after the CNC precision machining, the sound box support plate 253 is integrally welded on the outer side of the main installation shell.

[0079] It is to be noted that in the preparation process of the first side support plate 21 in step S2, the first column shell 211 and the first reinforcing plate 212 are respectively prepared, and the first reinforcing plate 212 is integrally welded in the cavity of the first column shell 211. Then, the outermost surface of the first column shell 211 and the outermost surface of the first reinforcing plate 212 are generally punched and shaped, thereby increasing the flatness of the first side support plate 21 and increasing the accuracy of the first side support plate 21 as a reference.

[0080] In step S4, the bottom end surface of the main mounting shell 251 is abutted against the horizontal reference of the lower support bar 24, and then the position of the main mounting shell 251 is adjusted along the length direction of the lower support bar 24 so that the outer side surface of the free end of the sound box support plate 253 abuts against the inner side surface of the first side support plate 21. Then, the face of the lower support bar 24 close to the support reinforcing edge 143 of the face shell 14 is used as the reference surface, and the final position of the main mounting shell 251 is positioned flush.

[0081] The required important reference dimensions mentioned in step S5 are the distance between the outer side surfaces of the first side support plate 21 and the second side support plate 22, the distance between the inner side surfaces of the first side support plate 21 and the second side support plate 22, to ensure the accuracy of the assembly reference of the remaining components in the tool support 2; the parallelism of the upper abutment bar 23 with the top of the face shell 14 as the reference and the distance therebetween, to ensure the position accuracy of the sound-producing display module; the parallelism between the upper abutment bar 23 and the lower support bar 24 and the distance therebetween, to ensure that the cantilever support 25 is not deformed by pressure and occupies the installation space of the sound-producing display module; and the vertical parallelism between the main mounting shell 251 and the upper abutment bar 23 and the lower support bar 24 after they are positioned flush, to ensure that the main mounting shell 251 does not protrude from the tool support 2 and provides a high-precision reference for the installation of the later sound-producing display module.

[0082] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application. Identical components are denoted by identical reference numerals. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the above description refer to the directions in the drawings, and the words "inner" and "outer" refer to the directions towards or away from the geometric center of a particular component. Therefore, any equivalent changes made in accordance with the structure, shape, principle of the present application should be covered within the protection scope of the present application.
