Description

Technical Field

[0001] This invention relates to the field of bearing grinding and processing technology, and in particular to a bearing processing apparatus. Background Technology

[0002] Bearings are an important component in mechanical equipment, used to support rotating mechanical parts, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. Bearings generally consist of an inner ring, an outer ring, and rolling elements. During the bearing manufacturing process, in order to ensure the service life and performance of the bearing, the inner and outer rings need to be ground to remove any burrs and improve the smoothness of the bearing.

[0003] A search revealed a patent document with publication number CN116038454B that discloses a bearing inner ring processing device, including a C-shaped plate and two symmetrical horizontal plates, which are slidably connected between the upper and lower inner walls of the C-shaped plate by a clamping assembly. Each of the two horizontal plates is fixedly connected to a frame, and each of the two frames is fixedly connected to a mutually symmetrical outer arc plate and an inner arc plate, with a gap between the outer arc plate and the inner arc plate.

[0004] The bearing inner ring machining device has the following shortcomings:

[0005] 1. When grinding bearings, only the inner ring or the outer ring can be processed at a time, and it is not possible to process both the inner and outer rings at the same time. Therefore, the inner and outer rings need to be replaced on the device during the overall processing, resulting in low overall processing efficiency.

[0006] 2. The bearing end face cannot be ground during the grinding process, and the overall grinding effect of the bearing is not ideal. After the grinding process is completed, other grinding equipment is required to grind the bearing end face, making the entire processing steps cumbersome.

[0007] 3. The fixing and grinding of bearings need to be carried out in steps. During the processing, the staff needs to check and adjust the fixing and grinding progress in real time. Improper operation can easily lead to ineffective grinding.

[0008] In summary, a bearing processing device needs to be designed. Summary of the Invention

[0009] To address the shortcomings of existing technologies, this invention provides a bearing processing apparatus that solves the problems mentioned in the background section.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A bearing processing device includes a bearing body and a base. The bearing body is composed of an inner ring and an outer ring. An operating table is rotatably mounted on the base, and a mounting frame is fixedly mounted on the side wall of the base. A fixed plate is mounted on the mounting frame via a telescopic rod, and a mounting plate is fixedly mounted on the bottom of the fixed plate. An internal grinding assembly is mounted on the mounting plate. The internal grinding assembly is used to grind the outer wall of the inner ring and the inner wall of the outer ring. The internal grinding assembly includes three fixed columns, and a grinding ball is fixedly mounted on the bottom of each fixed column. One fixed column is rotatably mounted on the mounting plate, and the other two fixed columns rotate and slide on the mounting plate. A drive mechanism that cooperates with the three fixed columns is mounted on the mounting plate.

[0012] A positioning component is installed on the operating table. The positioning component is used to position the bearing body and to grind the outer wall of the outer ring and the inner wall of the inner ring. The positioning component includes multiple outer clamping plates and multiple inner clamping plates. Each outer clamping plate cooperates with a corresponding inner clamping plate. A control mechanism that cooperates with the multiple outer clamping plates and inner clamping plates is installed on the operating table. A transmission component is installed on the base. The transmission component drives the control mechanism to operate through a drive mechanism.

[0013] Furthermore, multiple support columns are fixedly installed between the fixed plate and the mounting plate. The mounting plate has an arc-shaped through groove, which cooperates with two corresponding fixed columns. An arc-shaped groove is formed on the side wall of the arc-shaped through groove, and two positioning plates are slidably installed in the arc-shaped groove. The two positioning plates are rotatably connected to the two corresponding fixed columns. A limit post is fixedly installed on the upper end of one positioning plate, and two limit posts are fixedly installed on the upper end of the other positioning plate. A limit groove one and a limit groove two are formed on the side wall of the arc-shaped groove. The limit groove one is slidably engaged with two corresponding limit posts, and the limit groove two is slidably engaged with another limit post. The arc length of the limit groove one is equal to the arc length of the arc-shaped groove, and the arc length of the limit groove two is equal to half the arc length of the arc-shaped groove.

[0014] Furthermore, the drive mechanism consists of a servo motor, a drive shaft, a drive gear, and multiple connecting gears. The servo motor is fixedly mounted on the top of the mounting plate, the drive gear is fixedly connected to the output end of the servo motor via the drive shaft, and the multiple connecting gears are respectively fixedly mounted on the top of their respective fixed posts, with each connecting gear meshing with the drive gear.

[0015] Furthermore, the upper surface of the operating table is provided with multiple outer sliding grooves and multiple inner sliding grooves, and each outer sliding groove and inner sliding groove is slidably installed with a moving block. Each moving block is fixedly connected to the corresponding outer clamping plate and inner clamping plate. Multiple bidirectional lead screws are rotatably installed on the operating table, and each bidirectional lead screw is threaded to the corresponding moving block at both ends.

[0016] Furthermore, the control mechanism consists of a drive rod, a driving helical gear, and multiple driven helical gears. The drive rod is rotatably mounted on the base, and the top of the drive rod is also rotatably connected to the operating table. The driving helical gear is fixedly mounted on the top of the drive rod, and the multiple driven helical gears are respectively fixedly mounted on corresponding bidirectional lead screws, and all the driven helical gears mesh with the driving helical gear.

[0017] Furthermore, the transmission assembly comprises a first belt drive structure, a round rod, a connecting rod, a rotating shaft, a second belt drive structure, a mounting rod, a fixed gear, a fixed gear ring, an incomplete gear ring, and a aligning gear. The round rod is rotatably mounted on a fixed disc. The first belt drive structure is mounted between the round rod and the drive shaft. The connecting rod is rotatably mounted on a base and is slidably connected to the round rod. The rotating shaft and the mounting rod are both rotatably mounted on the bottom of the base. The second belt drive structure is mounted between the round rod and the rotating shaft. The fixed gear is fixedly mounted on the top of the rotating shaft. The fixed gear ring and the incomplete gear ring are both fixedly mounted on the mounting rod, and the fixed gear ring meshes with the fixed gear. The aligning gear is fixedly mounted on the bottom of the drive rod and engages with the incomplete gear ring.

[0018] Furthermore, the tooth pitches of the fixed gear, fixed gear ring, incomplete gear ring, and aligning gear are equal, the number of teeth and diameter of the fixed gear are smaller than those of the fixed gear ring, and the number of teeth and diameter of the incomplete gear ring are larger than those of the aligning gear.

[0019] Furthermore, a polygonal rod is fixedly installed at the bottom of the round rod, and a polygonal groove is provided on the upper side wall of the connecting rod to slide with the polygonal rod. A lifting groove is provided on the mounting frame to cooperate with the belt drive structure.

[0020] Furthermore, grinding discs are fixedly installed on the top of the operating table and the bottom of the mounting plate, and the two grinding discs are respectively matched with the upper and lower ends of the bearing body.

[0021] Compared with existing technologies, the advantages of this invention are:

[0022] 1: This bearing processing device has the advantage of being able to grind both the outer and inner rings simultaneously, which effectively improves the overall processing efficiency. Specifically, through the cooperation of the positioning component and the inner grinding component, the outer and inner rings can be effectively fixed on the operating table at the same time, and then the inner wall of the outer ring and the outer wall of the inner ring can be ground simultaneously.

[0023] 2: This bearing processing device has the advantage of being able to perform multi-face grinding on the bearing body without the need to use different devices for grinding, which further improves processing efficiency. Specifically, through the design of grinding balls, inner clamping plate, outer clamping plate and grinding disc, the grinding position on the bearing body can be switched during operation to achieve the effect of multi-face grinding.

[0024] 3: This bearing processing device has the advantages of high automation and simple operation. Specifically, through the cooperation of transmission components, drive mechanism and control mechanism, and the operation of a servo motor, it can automatically and orderly complete the positioning of the bearing body, grinding of the lower end face, grinding of the inner and outer walls and grinding of the upper end face, without the need for manual control of the operation process.

[0025] In summary, this invention, through the operation of a single servo motor, can automatically and orderly switch between positioning the bearing body, grinding the lower end face, grinding the inner and outer side walls, and grinding the upper end face, automatically completing an effective overall grinding process. This ensures a more ideal overall grinding effect for the bearing body, while significantly improving processing efficiency and facilitating mass production. Attached Figure Description

Detailed Implementation

[0039] Reference Figures 1-12 A bearing processing device includes a bearing body 1 and a base 2. The bearing body 1 consists of an inner ring and an outer ring. An operating table 3 is rotatably mounted on the base 2, and a mounting frame 8 is fixedly mounted on the side wall of the base 2. A fixed plate 10 is mounted on the mounting frame 8 via a telescopic rod 9, and a mounting plate 11 is fixedly mounted on the bottom of the fixed plate 10. Multiple support columns are fixedly mounted between the fixed plate 10 and the mounting plate 11. When the telescopic rod 9 is working, it can drive the mounting plate 11 to move up and down relative to the operating table 3 through the fixed plate 10. Grinding discs are fixedly mounted on the top of the operating table 3 and the bottom of the mounting plate 11, and the two grinding discs are respectively matched with the upper and lower ends of the bearing body 1. The grinding discs are divided into inner grinding discs and outer grinding discs. The inner grinding discs are used to grind the upper and lower end faces of the inner ring of the bearing, and the outer grinding discs are used to grind the upper and lower end faces of the outer ring of the bearing.

[0040] An internal grinding assembly is installed on the mounting plate 11. The internal grinding assembly is used to grind the outer wall of the inner ring and the inner wall of the outer ring. The internal grinding assembly includes three fixed posts 13. Each fixed post 13 has a grinding ball 14 fixedly installed at its bottom. The size of the grinding ball 14 is set to be less than or equal to the size of the rolling element. During the grinding process, the grinding ball 14 is positioned between the inner ring and the outer ring. Then, the grinding ball 14 is rotated between the inner ring and the outer ring to simultaneously grind the outer wall of the inner ring and the inner wall of the outer ring.

[0041] One of the fixed posts 13 is rotatably mounted on the mounting plate 11, and the other two fixed posts 13 are both rotatable and slide on the mounting plate 11. When the bearing body 1 has not yet been polished, the three fixed posts 13 are close to each other on the mounting plate 11. When the bearing body 1 needs to be polished, the inner ring and the outer ring are placed together on the operating table 3, with the inner ring inside the outer ring. At the same time, the outer ring is made as coaxial as possible with the operating table 3. In addition, the inner ring and the outer ring are placed eccentrically so that the maximum distance between them can accommodate three polishing balls 14 at the same time. Then, the telescopic rod 9 is activated so that the mounting plate 11 moves the three polishing balls 14 down and into the space between the outer ring and the inner ring.

[0042] The mounting plate 11 has an arc-shaped through groove 12, which is matched with two corresponding fixed posts 13. The side wall of the arc-shaped through groove 12 has an arc-shaped groove, and two positioning plates 15 are slidably installed in the arc-shaped groove. The two positioning plates 15 are rotatably connected to the two corresponding fixed posts 13. One positioning plate 15 has a limit post 16 fixedly installed on its upper end, and the other positioning plate 15 has two limit posts 16 fixedly installed on its upper end. The side wall of the arc-shaped groove has a limit groove one and a limit groove two. Limit groove one is slidably matched with two corresponding limit posts 16, and limit groove two is slidably matched with another limit post 16. With the design of the arc-shaped groove, the movement direction of the two positioning plates 15 in the arc-shaped through groove 12 can be limited, so that the three fixed posts 13 can be arranged in a circular array on the mounting plate 11 after unfolding. At this time, the position change of the three polishing balls 14 after unfolding can be used to make the inner ring and the outer ring coaxial with the operating table 3.

[0043] The arc length of the first limiting groove is equal to the arc length of the arc groove, and the arc length of the second limiting groove is equal to half the arc length of the arc groove. The purpose of this size design is to limit the maximum distance that the two movable fixed columns 13 can move on the mounting plate 11 respectively, so that the three fixed columns 13 after unfolding can be stably distributed in a circular array, thereby ensuring that the inner and outer rings can be stably coaxially placed on the operating table 3 during the grinding process.

[0044] The mounting plate 11 is equipped with a drive mechanism that engages with three fixed posts 13. The drive mechanism consists of a servo motor, a drive shaft, a drive gear 18, and multiple connecting gears 17. The servo motor is fixedly mounted on the top of the mounting plate 11. The drive gear 18 is fixedly connected to the output end of the servo motor via the drive shaft. The multiple connecting gears 17 are respectively fixedly mounted on the top of their respective fixed posts 13, and each connecting gear 17 meshes with the drive gear 18. Figure 12 As shown, when the servo motor rotates clockwise, it drives the drive gear 18 to rotate clockwise simultaneously. Then, through the meshing effect between the drive gear 18 and the connecting gear 17, the connecting gear 17 can rotate counterclockwise. At the same time, the tangential force applied by the drive gear 18 to the connecting gear 17 will also cause the two movable fixed columns 13 to move clockwise within the arc-shaped through groove 12. Thus, the operation of the servo motor can drive the simultaneous rotation of multiple grinding balls 14 and the arc-shaped movement of one of the grinding balls 14. To ensure that the rotation of the drive gear 18 can drive the fixed column 13 to move smoothly within the arc-shaped through groove 12, the rotational resistance between the connecting gear 17 and the positioning plate 15 is set to be greater than the movement resistance of the positioning plate 15 within the arc-shaped groove.

[0045] The operating table 3 is equipped with a positioning component. The positioning component is used to position the bearing body 1 and to grind the outer wall of the outer ring and the inner wall of the inner ring. The positioning component includes multiple outer clamping plates 4 and multiple inner clamping plates 5. Each outer clamping plate 4 cooperates with a corresponding inner clamping plate 5. Grinding blocks are fixedly installed at the ends of the outer clamping plates 4 and the inner clamping plates 5 that are close to each other. The cooperation of multiple outer clamping plates 4 is used to clamp the outer wall of the outer ring. At the same time, when the outer clamping plate 4 is just in contact with the outer wall of the outer ring, if it rotates relative to the outer ring, the outer wall of the outer ring can also be ground. The cooperation of multiple inner clamping plates 5 is used to support and fix the inner wall of the inner ring. At the same time, the inner clamping plates 5 also have the function of grinding the inner wall of the inner ring.

[0046] The operating table 3 is equipped with a control mechanism that cooperates with multiple outer clamping plates 4 and inner clamping plates 5. Multiple outer sliding grooves 32 and multiple inner sliding grooves 34 are provided on the upper surface of the operating table 3. Each outer sliding groove 32 and inner sliding groove 34 has a movable block 6 slidably installed in it. Each movable block 6 is fixedly connected to the corresponding outer clamping plate 4 and inner clamping plate 5. Multiple bidirectional screws 7 are rotatably installed on the operating table 3. Each bidirectional screw 7 is threaded to the corresponding movable block 6 at both ends. The design of the bidirectional screw 7 allows the outer clamping plates 4 and inner clamping plates 5 connected at both ends to move closer to each other or further away from each other when it rotates. The design of the outer sliding grooves 32 and inner sliding grooves 34 is used to limit the movement direction of the outer clamping plates 4 and inner clamping plates 5 on the operating table 3.

[0047] The control mechanism consists of a drive rod 28, a driving helical gear 30, and multiple driven helical gears 31. The drive rod 28 is rotatably mounted on the base 2, and the top of the drive rod 28 is also rotatably connected to the operating table 3. The driving helical gear 30 is fixedly mounted on the top of the drive rod 28, and the multiple driven helical gears 31 are respectively fixedly mounted on the corresponding bidirectional lead screws 7. The multiple driven helical gears 31 mesh with the driving helical gear 30. Under the meshing action of the driving helical gear 30 and the driven helical gears 31, when the drive rod 28 rotates, it can simultaneously drive the multiple bidirectional lead screws 7 to rotate. Therefore, the positions of multiple outer clamping plates 4 and inner clamping plates 5 can be controlled simultaneously, and the inner and outer rings can be fixed on the operating table 3 synchronously.

[0048] A transmission assembly is installed on the base 2. The transmission assembly drives the control mechanism through the drive mechanism. The transmission assembly consists of a belt drive structure 19, a round rod 20, a connecting rod 21, a rotating shaft 22, a second belt drive structure 23, a mounting rod 25, a fixed gear 24, a fixed gear ring 26, an incomplete gear ring 27, and a positioning gear 29. The round rod 20 is rotatably mounted on the fixed disk 10. The belt drive structure 19 is installed between the round rod 20 and the drive shaft. Under the action of the belt drive structure 19, when the servo motor is working, it can drive the round rod 20 to rotate in the same direction.

[0049] The connecting rod 21 is rotatably mounted on the base 2 and is slidably connected to the round rod 20. An arc-shaped block is fixedly mounted on the side wall of the base 2, and the connecting rod 21 is rotatably connected to the arc-shaped block. An installation block is fixedly mounted on the side wall of the fixed plate 10 via a crossbar. The round rod 20 is rotatably connected to the installation block. A polygonal rod is fixedly mounted on the bottom of the round rod 20. A polygonal groove is provided on the upper side wall of the connecting rod 21 to slide with the polygonal rod. Through the cooperation of the polygonal rod and the polygonal groove, the round rod 20 can move up and down relative to the connecting rod 21. At the same time, due to the polygonal design, it can ensure effective transmission between the two even after the round rod 20 moves relative to the connecting rod 21. Therefore, when the telescopic rod 9 works to move the fixed plate 10 up and down relative to the operating table 3, the servo motor can also drive the round rod 20 and the connecting rod 21 to rotate simultaneously. The mounting frame 8 is provided with a lifting groove 33 that cooperates with the belt drive structure 19. The design of the lifting groove 33 can ensure that the belt drive structure 19 can move up and down smoothly relative to the mounting frame 8 synchronously when the fixed plate 10 moves up and down.

[0050] The rotating shaft 22 and the mounting rod 25 are both rotatably mounted on the bottom of the base 2. The second belt drive structure 23 is installed between the round rod 20 and the rotating shaft 22. The fixed gear 24 is fixedly mounted on the top of the rotating shaft 22. The fixed gear ring 26 and the incomplete gear ring 27 are both fixedly mounted on the mounting rod 25, and the fixed gear ring 26 meshes with the fixed gear 24. The aligning gear 29 is fixedly mounted on the bottom of the drive rod 28, and the aligning gear 29 cooperates with the incomplete gear ring 27. When the connecting rod 21 rotates clockwise, the rotating shaft 22 is driven to rotate simultaneously through the second belt drive structure 23. Then, under the meshing action of the fixed gear 24 and the fixed gear ring 26, the mounting rod 25 rotates counterclockwise, thereby causing the incomplete gear ring 27 to rotate counterclockwise. When the incomplete gear ring 27 and the aligning gear 29 are in a meshing state, the drive rod 28 can be driven to rotate clockwise simultaneously, thereby causing the multiple outer clamping plates 4 and the multiple inner clamping plates 5 to move closer to each other, thereby fixing the outer ring and the inner ring.

[0051] After the multiple outer clamping plates 4 and multiple inner clamping plates 5 have completed the fixation of the inner and outer rings, the rotation of the bidirectional lead screw 7 is obstructed. Therefore, the continued rotation of the drive rod 28 can drive the operating table 3 to rotate clockwise relative to the base 2. At this time, the inner and outer rings can automatically rotate relative to the multiple grinding balls 14, realizing the simultaneous grinding of the outer wall of the inner ring and the inner wall of the outer ring. During the grinding process, the multiple grinding balls 14 will also rotate on their own, thus avoiding the problem that the overall shape of the grinding balls 14 will change due to prolonged friction and affect the grinding effect. At the same time, during the grinding process, since the inner and outer rings are fixed on the operating table 3, the mounting plate 11 also rotates relative to the inner and outer rings. At this time, the grinding disc on it can be used to complete the grinding of the upper surface of the inner and outer rings. When the incomplete gear ring 27 and the aligning gear 29 are in a separated state... When the operating table 3 is stationary, the pressure of the mounting plate 11 on the inner and outer rings, combined with the squeezing and friction of the grinding balls 14 with the inner and outer rings, will cause the inner and outer rings to rotate to a certain extent relative to the operating table 3. At this time, the grinding discs on the operating table 3 can be used to grind the lower surfaces of the inner and outer rings. In addition, when the incomplete gear ring 27 rotates to the point where it is about to separate from the aligning gear 29, the outer clamping plate 4 is in contact with the outer wall of the outer ring, and the inner clamping plate 5 is in contact with the inner wall of the inner ring. Then, when the incomplete gear ring 27 separates from the aligning gear 29, the rotation of the inner and outer rings relative to the operating table 3 will also cause the outer clamping plate 4 and the inner clamping plate 5 to grind the inner wall of the inner ring and the outer wall of the outer ring. After that, when the incomplete gear ring 27 rotates to mesh with the aligning gear 29 again, the outer clamping plate 4 and the inner clamping plate 5 can continue to move until the outer and inner rings are fixed.

[0052] The tooth pitches of the fixed gear 24, fixed gear ring 26, incomplete gear ring 27, and aligning gear 29 are equal. The number of teeth and diameter of the fixed gear 24 are smaller than those of the fixed gear ring 26, while the number of teeth and diameter of the incomplete gear ring 27 are larger than those of the aligning gear 29. The advantage of this size design is that it ensures sufficient grinding time for grinding the upper and lower end faces of the inner and outer rings, as well as the inner and outer side walls, thereby ensuring the consistency of the overall grinding process of the bearing body 1 as much as possible.

[0053] The servo motor, drive shaft, arc block, crossbar, mounting block, polygonal rod, and polygonal groove are not shown in the figure. The servo motor can be a mounting bracket 8 with a lifting groove 33 that cooperates with the belt drive structure 19. The telescopic rod 9 can be a YMD-608 electric telescopic rod. The belt drive structure 19 and the belt drive structure 23 are existing technologies, and their working principles and specific structures will not be described in detail here.

[0054] The working principle of a bearing processing device in this invention is as follows:

[0055] Placement of bearing body 1: Place the inner ring and outer ring together on the operating table 3, with the inner ring inside the outer ring, and make the outer ring as coaxial as possible with the operating table 3. In addition, place the inner ring and outer ring eccentrically so that the maximum distance between them can accommodate three grinding balls 14 at the same time. Then, activate the telescopic rod 9 so that the mounting plate 11 moves the three grinding balls 14 down and into the space between the outer ring and the inner ring.

[0056] Then, the servo motor is started clockwise, causing the drive gear 18 to drive the connecting gear 17 to rotate and move simultaneously, so that multiple fixed columns 13 are distributed in a circular array on the mounting plate 11, making the inner and outer rings coaxial.

[0057] Fixing the bearing body 1, grinding the lower end face, and grinding the inner wall of the inner ring and the outer wall of the outer ring: During the clockwise rotation of the servo motor, multiple fixed columns 13 are unfolded. The operation of the belt drive structure 19 drives the round rod 20 and the connecting rod 21 to rotate simultaneously. At this time, the rotating shaft 22 is driven to rotate through the belt drive structure 23. Then, under the meshing effect of the fixed gear 24 and the fixed gear ring 26, the mounting rod 25 rotates counterclockwise. At this time, the incomplete gear ring 27 and the aligning gear 29 are in a meshing state. Through the meshing of the active helical gear 30 and multiple driven helical gears 31, multiple inner clamping plates 5 and multiple outer clamping plates 4 are brought closer to the inner ring and outer ring respectively.

[0058] During this process, as the grinding ball 14 continues to rotate, the friction between the grinding ball 14 and the inner and outer rings will cause the inner and outer rings to rotate on the operating table 3. At this time, the inner and outer rings will cooperate with the two grinding discs to achieve the grinding treatment of the lower end face. When the incomplete gear ring 27 is separated from the aligning gear 29, the inner clamping plate 5 is exactly in contact with the inner wall of the inner ring and the outer clamping plate 4 is exactly in contact with the outer wall of the outer ring. At this time, the rotation of the inner and outer rings driven by the grinding ball 14 will also cause the inner and outer rings to rotate relative to the inner clamping plate 5 and the outer clamping plate 4 respectively, thereby achieving the grinding treatment of the inner wall of the inner ring and the outer wall of the outer ring.

[0059] Grinding of the upper end face, outer wall of the inner ring, and inner wall of the outer ring of the bearing body 1: As the servo motor continues to rotate clockwise, the incomplete gear ring 27 meshes with the alignment gear 29 again, causing the inner clamping plate 5 and the outer clamping plate 4 to continue moving until the inner ring and the outer ring are fixed on the operating table 3. At this time, since the movement of the inner clamping plate 5 and the outer clamping plate 4 is blocked, the continuous rotation of the drive rod 28 will drive the operating table 3 to rotate at the same time, causing the bearing body 1 fixed on it to rotate relative to the mounting plate 11 and the multiple grinding balls 14, thereby completing the grinding of the upper end face, outer wall of the inner ring, and inner wall of the outer ring of the bearing body 1.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
