Description

Technical Field

[0001] This application belongs to the field of CNC machining technology, and specifically relates to a jetting device and machining equipment. Background Technology

[0002] When machining workpieces on CNC machining equipment, after drilling or tapping operations using a cutting tool, the tool head needs to be cooled. In related technologies, an oil-air mixture is sprayed onto the cutting tool head for rapid cooling. However, to ensure the spraying device is aligned with the cutting tool head, the spray angle needs to be adjusted multiple times, and the spraying action repeated to observe the spray position, which is time-consuming. Utility Model Content

[0003] In view of the above situation, it is necessary to provide a spraying device and processing equipment that can accurately spray the mixture onto the cutting head.

[0004] Embodiments of this application provide a spraying device, including a positioning assembly and a spraying assembly. The positioning assembly is used to connect a cutter head and includes a positioning element. The spraying assembly includes an adjustment structure and a nozzle. The adjustment structure is connected to the nozzle, which is used to spray a mixture. The nozzle is provided with a mating element for connecting to the positioning element. The adjustment structure is used to move the nozzle toward the positioning assembly and also to adjust the angle of the nozzle so that the mating element can connect to the positioning element, and the nozzle sprays the mixture toward the cutter head.

[0005] In the aforementioned spraying device, when the mating component is connected to the positioning component, the mixture sprayed by the nozzle acts on the positioning assembly, connecting the positioning assembly to the cutter head. An adjusting structure drives the nozzle towards the positioning assembly and rotates it to adjust the nozzle angle, connecting the mating component to the positioning component. This positions the nozzle relative to the positioning assembly, allowing the sprayed mixture to act on the cutter head connected to the positioning assembly for cooling and lubrication. When the nozzle is adjusted by the adjusting structure to connect the mating component to the positioning component, the sprayed mixture can be precisely sprayed onto the cutter head. The positioning component positions the mating component to determine the nozzle's position and angle, facilitating nozzle adjustment.

[0006] In some embodiments, the adjustment structure includes a drive member, a mounting plate, and a rotating member. The drive member is connected to the mounting plate, and the rotating member is rotatable relative to the mounting plate. The drive member is used to drive the mounting plate and the rotating member to move toward the positioning assembly. The end of the rotating member away from the mounting plate is used to connect to a nozzle to adjust the angle of the nozzle.

[0007] The driving component moves the nozzle toward the positioning assembly, bringing the nozzle closer to the cutter head. The rotating component rotates relative to the mounting plate, causing the nozzle to rotate and adjust its angle so that the nozzle can spray the mixture toward the cutter head.

[0008] In some embodiments, the mounting plate is provided with a guide groove, and a connector is connected to the rotating component. The connector passes through the guide groove, allowing the rotating component to move along the guide groove and rotate relative to the mounting plate. The rotating component moves relative to the guide groove through the connector to drive the nozzle to rotate, thereby adjusting the nozzle angle.

[0009] The adjustment structure also includes a clamping component connected to the mounting plate and used to clamp the rotating component, fixing it relative to the mounting plate. By clamping the rotating component and fixing it relative to the mounting plate, the nozzle can be maintained at the adjusted angle.

[0010] In some embodiments, the clamping member includes two fixed plates and two locking bolts. The two fixed plates are spaced apart on the mounting plate along a first direction. The locking bolts include clamping heads. Each locking bolt is threaded and passes through a fixed plate, so that the clamping head abuts against the rotating member, thereby clamping the rotating member along the first direction with the two locking bolts.

[0011] By tightening the two locking bolts, the two locking bolts gradually pass through the corresponding fixing plates until the two clamping heads abut against the opposite ends of the rotating part along the first direction to prevent the rotating part from rotating relative to the mounting plate. At this time, both locking bolts are threaded to the corresponding fixing plates, thereby fixing the rotating part to the mounting plate.

[0012] In some embodiments, the positioning member is provided with a positioning groove, and the mating member includes a protrusion that can be inserted into the positioning groove when the nozzle sprays the mixture onto the cutter head.

[0013] The nozzle is positioned relative to the positioning component by inserting a protrusion into the positioning groove, thereby positioning the nozzle relative to the cutter head and allowing the nozzle to spray the mixture toward the cutter head.

[0014] In some embodiments, the protrusion is a polygonal column. This allows the protrusion to be inserted into the positioning groove only when the nozzle is at a preset angle and a preset position.

[0015] In some embodiments, the nozzle includes a spray channel with an inlet end and an outlet end. The mixture enters the spray channel through the inlet end and is sprayed toward the cutter head through the outlet end. The size of the inlet end is larger than the size of the outlet end to increase the pressure of the mixture sprayed toward the cutter head.

[0016] A larger inlet allows a larger volume of mixture to enter the injection channel, while a smaller outlet allows for a higher pressure of the mixture ejected from the nozzle, thus increasing the nozzle's injection force.

[0017] In some embodiments, the cutter head is connected to a connecting shaft that extends along a first direction. The injection channel includes a first channel and a second channel. Viewed along the first direction, the outlet end of the first channel is spaced apart from the outlet end of the second channel, such that the mixture injected through the first channel and the mixture injected through the second channel can act on the cutter head connected by connecting shafts of different extension lengths.

[0018] When the connecting shaft extends a shorter length along the first direction, the cutter head connected to the shorter connecting shaft is cooled and lubricated by the mixture sprayed in the first channel. When the connecting shaft extends a longer length along the first direction, the cutter head connected to the longer connecting shaft is cooled and lubricated by the mixture sprayed in the second channel.

[0019] In some embodiments, the positioning component further includes a connector that is detachably connected to the positioning component and is used to attach the cutter head.

[0020] The connector is fitted onto the cutter head and then connected to the positioning element. This allows for the positioning of the relative position between the cutter head and the positioning element. The nozzle is connected to the positioning element via a mating part to position and angle the nozzle relative to the cutter head. Removing the connector from the positioning element and the cutter head ensures that the nozzle's position and angle are correctly positioned without affecting the cutter head's operation.

[0021] Embodiments of this application also provide a processing device, including a power structure, a connecting shaft, a cutting head, and a spraying device as described in the previous embodiment. The connecting shaft is connected to the cutting head, the power structure is connected to the connecting shaft and is used to drive the connecting shaft and the cutting head to move, so that the cutting head processes the workpiece, and the spraying device is connected to the housing of the power structure and is used to spray a mixture toward the cutting head.

[0022] In the aforementioned processing equipment, the connecting shaft and the cutting head are driven to rotate by a power structure, enabling the cutting head to process the workpiece. A mixture is sprayed onto the cutting head by a spraying device, thereby lubricating and rapidly cooling the cutting head. Attached Figure Description

[0033] The following detailed description, in conjunction with the accompanying drawings, will further illustrate this application. Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0036] In the description of the embodiments of this application, technical terms such as "first" and "second" are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined.

[0037] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0038] When machining workpieces on CNC machining equipment, after drilling or tapping operations using a cutting tool, the tool head needs to be cooled. In related technologies, an oil-air mixture is sprayed onto the cutting tool head for rapid cooling. However, to ensure the spraying device is aligned with the cutting tool head, the spray angle needs to be adjusted multiple times, and the spraying action repeated to observe the spray position, which is time-consuming.

[0039] Embodiments of this application provide a spraying device, including a positioning assembly and a spraying assembly. The positioning assembly is used to connect a cutter head and includes a positioning element. The spraying assembly includes an adjustment structure and a nozzle. The adjustment structure is connected to the nozzle, which is used to spray a mixture. The nozzle is provided with a mating element for connecting to the positioning element. The adjustment structure is used to move the nozzle toward the positioning assembly and also to adjust the angle of the nozzle so that the mating element can connect to the positioning element, and the nozzle sprays the mixture toward the cutter head.

[0040] In the aforementioned spraying device, when the mating component is connected to the positioning component, the mixture sprayed by the nozzle acts on the positioning assembly, connecting the positioning assembly to the cutter head. An adjusting structure drives the nozzle towards the positioning assembly and rotates it to adjust the nozzle angle, connecting the mating component to the positioning component. This positions the nozzle relative to the positioning assembly, allowing the sprayed mixture to act on the cutter head connected to the positioning assembly for cooling and lubrication. When the nozzle is adjusted by the adjusting structure to connect the mating component to the positioning component, the sprayed mixture can be precisely sprayed onto the cutter head. The positioning component positions the mating component to determine the nozzle's position and angle, facilitating nozzle adjustment.

[0041] The embodiments of this application will be further described below with reference to the accompanying drawings. Unless otherwise specified, the various embodiments in this application can be combined with each other.

[0042] Please see Figure 1In this embodiment, the first direction and the second direction are defined to be perpendicular. The first direction is the direction parallel to Z in the figure, and the second direction is the direction parallel to X in the figure.

[0043] For ease of reference to the diagrams, the first direction will be referred to as "first direction Z" and the second direction as "second direction X" in the following text.

[0044] An embodiment of this application provides a processing apparatus 200, including a power structure 210, a connecting shaft 220, a cutting head 230, and a spraying device 100. The connecting shaft 220 extends along a first direction Z and is fixedly connected to the cutting head 230. The power structure 210 is connected to the connecting shaft 220. The power structure 210 is used to drive the connecting shaft 220 and the cutting head 230 to move, so that the cutting head 230 processes the workpiece. The spraying device 100 is connected to the housing of the power structure 210 to facilitate the installation and fixation of the spraying device 100. The spraying device 100 is used to spray a mixture toward the cutting head 230 to lubricate and cool the cutting head 230.

[0045] The processing equipment 200 drives the connecting shaft 220 and the cutting head 230 to rotate through the power structure 210, so that the cutting head 230 can drill or tap the workpiece. After the cutting head 230 processes the workpiece multiple times, the cutting head 230 is prone to overheating. The spraying device 100 sprays a mixture onto the cutting head 230 to lubricate and cool the cutting head 230 quickly, in preparation for the cutting head 230 to process the workpiece again.

[0046] Please see Figure 2 In some embodiments, the spraying device 100 includes a positioning assembly 10 and a spraying assembly 20. The positioning assembly 10 is used to connect to the cutter head 230 to position the cutter head 230. The spraying assembly 20 includes an adjustment structure 21 and a nozzle 22. The adjustment structure 21 is connected to the nozzle 22. The adjustment structure 21 is used to adjust the position and angle of the nozzle 22.

[0047] The positioning component 10 includes a positioning element 11. (See also...) Figure 3 The nozzle 22 is provided with a mating part 221, which can be connected to the positioning part 11. The nozzle 22 is driven to move toward the positioning assembly 10 by the adjusting structure 21, and the angle of the nozzle 22 is adjusted by the adjusting assembly, so that the mating part 221 is connected to the positioning part 11, thereby positioning the position and angle of the nozzle 22 relative to the positioning assembly 10 and the cutter head 230.

[0048] Nozzle 22 is used to spray the mixture. When nozzle 22 is at a preset angle and a preset position, the mixture can be precisely sprayed onto the cutter head 230 through nozzle 22 to lubricate and cool the cutter head 230. Specifically, when the positioning member 11 is connected to the mating member 221, nozzle 22 is at the preset angle and the preset position.

[0049] In some embodiments, the mixture is an oil-gas mixture medium used to lubricate and cool the cutter head 230.

[0050] In use, the positioning component 10 is connected to the cutter head 230. The adjusting structure 21 drives the nozzle 22 to move toward the positioning component 10 and rotates the nozzle 22 to adjust its angle, thereby connecting the mating part 221 with the positioning part 11. This positions the nozzle 22 relative to the positioning component 10, allowing the mixture to be precisely sprayed through the nozzle 22 onto the cutter head 230 connected to the positioning component 10 for cooling and lubrication. Therefore, the spraying device 100 connects to the cutter head 230 via the positioning component 10 and then to the mating part 221 via the positioning part 11, thus positioning the nozzle 22's position and angle. Adjusting the nozzle 22 is simple and convenient.

[0051] Please see Figure 2 and Figure 3 In some embodiments, the adjustment structure 21 includes a drive member 211, a mounting plate 212, and a rotating member 213. The drive member 211 is fixedly connected to the mounting plate 212. The rotating member 213 is rotatable relative to the mounting plate 212. The drive member 211 is used to drive the mounting plate 212 and the rotating member 213 to move along a second direction X toward the positioning assembly 10. One end of the rotating member 213 away from the mounting plate 212 is used to fixably connect to the nozzle 22.

[0052] The mounting plate 212 is moved along the second direction X by the drive member 211 to adjust the position of the nozzle 22 in the second direction X, so that the nozzle 22 is located in a preset position. The angle of the nozzle 22 is adjusted by driving the rotating member 213 to rotate relative to the mounting plate 212, so that the nozzle 22 is located at a preset angle, and the nozzle 22 can spray the mixture toward the cutter head 230.

[0053] In some embodiments, after the nozzle 22 is adjusted to a preset angle, the rotating member 213 is fixed relative to the mounting plate 212 to avoid repeated adjustments, so that the spraying device 100 can be used throughout the entire product cycle after one adjustment without the need for secondary adjustments.

[0054] In some embodiments, the drive element 211 is a cylinder, which drives the mounting plate 212 to move along the second direction X. When the piston of the cylinder extends a preset distance, the nozzle 22 is located at a preset position.

[0055] The piston of the cylinder is controlled by the program to retract when the cutter head 230 is used to process the workpiece, so as to prevent the spraying component 20 from affecting the workpiece processing of the cutter head 230; the piston is also extended from the cylinder when the cutter head 230 needs to be cooled or lubricated, and the piston is controlled to extend a preset distance so that the nozzle 22 returns to the preset position.

[0056] Please see Figure 4 and Figure 5 In some embodiments, the mounting plate 212 is provided with a guide groove 212a. The rotating member 213 is connected to a connector 2131. The connector 2131 passes through the guide groove 212a, allowing the rotating member 213 to move along the guide groove 212a and rotate relative to the mounting plate 212, thereby enabling the rotating member 213 to drive the nozzle 22 to rotate relative to the mounting plate 212.

[0057] In some embodiments, the end of the rotating member 213 away from the mounting plate 212 is fixedly connected to the nozzle 22, so that the nozzle 22 can rotate together with the rotating member 213.

[0058] In some embodiments, the nozzle 22 has a boss 223 on the side facing the rotating member 213, and the rotating member 213 has a groove 2132 on the side facing the nozzle 22. The groove 2132 is inserted into the boss 223. The boss 223 is rectangular and is inserted into the groove 2132 to position the angle of the nozzle 22 relative to the rotating member 213, so as to prevent the nozzle 22 from rotating relative to the rotating member 213. After the boss 223 is inserted into the groove 2132, the nozzle 22 and the rotating member 213 are locked by screws, bolts, or threaded screws to fix the nozzle 22 relative to the rotating member 213.

[0059] The rotating component 213 can move along the guide groove 212a via the connector 2131, causing the rotating component 213 to drive the nozzle 22 to rotate relative to the mounting plate 212, thereby adjusting the angle of the nozzle 22; the rotating component 213 can also rotate within the guide groove 212a via the connector 2131, causing the rotating component 213 to rotate together with the connector 2131 relative to the mounting plate 212, thereby adjusting the angle of the nozzle 22.

[0060] In some embodiments, the plug-in member 2131 is fixedly connected or threadedly connected to the rotating member 213. This application does not limit this, and those skilled in the art can choose according to the actual situation.

[0061] In some embodiments, the connector 2131 includes a screw, bolt, or threaded rod, allowing the connector 2131 to pass through the guide groove 212a and be threadedly connected to the rotating member 213. This application does not limit the scope of the invention, and those skilled in the art can make the appropriate choice based on the specific circumstances.

[0062] In some embodiments, the guide groove 212a is an arc-shaped groove. When the connector 2131 moves along the guide groove 212a, it can adjust the position of the rotating member 213 and the nozzle 22 along the first direction Z, and also adjust the angle of the rotating member 213 and the nozzle 22 relative to the mounting plate 212.

[0063] In some embodiments, when the nozzle 22 is at a preset angle, that is, after the mating part 221 is connected to the positioning part 11, the mounting plate 212 and the rotating part 213 are connected by the fixing part 214, so that the mounting plate 212 and the rotating part 213 are relatively fixed to prevent the angle of the nozzle 22 from changing.

[0064] In some embodiments, the fastener 214 includes screws to enable threaded connection between the fastener 214 and the mounting member 213, facilitating the installation of the fastener 214. The fastener 214 may also include screws or threaded rods; this application does not limit the choice, and those skilled in the art can select according to the actual situation.

[0065] Please see Figures 3 to 5 In some embodiments, the adjustment structure 21 further includes a clamping member 23. The clamping member 23 is connected to the mounting plate 212 and is used to clamp the rotating member 213, thereby fixing the rotating member 213 relative to the mounting plate 212.

[0066] The clamping member 23 clamps one end of the rotating member 213 near the mounting plate 212, thereby further fixing the mounting plate 212 and the rotating member 213 relative to each other, making the connection between the mounting plate 212 and the rotating member 213 more stable, so as to further prevent the angle of the nozzle 22 from changing.

[0067] In some embodiments, the clamping member 23 includes two fixing plates 231 and two locking bolts 232. The two fixing plates 231 are spaced apart along a first direction Z and fixedly disposed on the mounting plate 212. Each locking bolt 232 includes a clamping head 232a. Each locking bolt 232 is threaded and passes through a fixing plate 231, so that the clamping head 232a can abut against the rotating member 213.

[0068] Tighten the two locking bolts 232 counterclockwise to clamp the rotating part 213 in the first direction Z, fixing the rotating part 213 relative to the mounting plate 212. Tighten the two locking bolts 232 clockwise to loosen the rotating part 213, allowing it to rotate relative to the mounting plate 212 after the fixing part 214 is removed from the mounting plate 212 and the rotating part 213. When the two locking bolts 232 abut against the rotating part 213, both locking bolts 232 are threadedly connected to the corresponding fixing plate 231 to prevent the locking bolts 232 from moving relative to the fixing plate 231.

[0069] Please see Figures 5 to 7 In some embodiments, the positioning member 11 is provided with a positioning groove 1101. The mating member 221 includes a protrusion 2211. The protrusion 2211 can be inserted into the positioning groove 1101 when the nozzle 22 sprays the mixture onto the cutter head 230.

[0070] The protrusion 2211 is inserted into the positioning groove 1101 to position the nozzle 22 relative to the positioning component 10, thereby positioning the nozzle 22 relative to the cutter head 230, so that the nozzle 22 can spray the mixture toward the cutter head 230.

[0071] Please see Figures 5 to 7 In some embodiments, the protrusion 2211 is a polygonal column. This allows the protrusion 2211 to be inserted into the positioning groove 1101 only when the nozzle 22 is at a preset angle and a preset position.

[0072] Please see Figure 6 In some embodiments, the positioning assembly 10 further includes a connector 12. The connector 12 is detachably connected to the positioning assembly 11. The connector 12 is used to attach the cutter head 230.

[0073] In some embodiments, the connector 12 has a through hole 1204, and the positioning member 11 has a threaded hole 1102 for threaded connection of a threaded fastener 111. The threaded fastener 111 passes through the through hole 1204 and is threadedly connected to the threaded hole 1102, thereby allowing the connector 12 and the positioning member 11 to be connected by the threaded fastener 111. The threaded fastener 111 is connected to the connector 12 and the positioning member 11 by tightening it counterclockwise, and the threaded fastener 111 is removed from the connector 12 and the positioning member 11 by tightening it clockwise.

[0074] In some embodiments, the threaded fastener 111 includes a screw, bolt, or threaded rod. This application does not limit the choice, and those skilled in the art can select the appropriate method based on the specific circumstances.

[0075] In some embodiments, the connector 12 has two through holes 1204, which are spaced apart along a first direction Z. The positioning member 11 has two threaded holes 1102, which are spaced apart along a first direction Z. Each threaded hole 1102 is threadedly connected to a threaded fastener 111, allowing the connector 12 and the positioning member 11 to be detachably connected via the two threaded fasteners 111, thus making the connection between the connector 12 and the positioning member 11 more stable.

[0076] Please see Figure 7In some embodiments, the connector 12 includes a first receiving groove 1201 and a second receiving groove 1202. The size of the first receiving groove 1201 is larger than the size of the second receiving groove 1202, and the first receiving groove 1201 communicates with the second receiving groove 1202 to form a stop surface 1203. When the connector 12 is sleeved on the cutter head 230, the connecting shaft 220 is located in the first receiving groove 1201 and abuts against the stop surface 1203, while the cutter head 230 passes through the second receiving groove 1202. The stop surface 1203 abuts against the connecting shaft 220 to position the connector 12 relative to the connecting shaft 220.

[0077] In some embodiments, the connector 12 is provided with a positioning hole 1205, which communicates with the first receiving groove 1201 and is used to connect the abutment member 121. The abutment member 121 is inserted into the positioning hole 1205 and abuts against the connecting shaft 220 in the first receiving groove 1201 to abut against the first receiving groove 1201.

[0078] In some embodiments, the abutment 121 includes a pin or a shaft. The abutment 121 also includes a screw or bolt, which is threadedly connected to and passes through the positioning hole 1205 to abut against the connecting shaft 220 within the first receiving groove 1201. This application does not limit the scope of the application, and those skilled in the art can make the appropriate choice based on the actual situation.

[0079] In use, first, fit the connector 12 onto the connecting shaft 220 and the cutter head 230. Insert the abutment 121 into the positioning hole 1205 and abut against the connecting shaft 220, so that the connector 12 is stably connected to the connecting shaft 220. Then, adjust the position and angle of the nozzle 22 by adjusting the adjustment structure 21, so that the mating part 221 connects to the positioning part 11, thereby positioning the position and angle of the nozzle 22 relative to the cutter head 230, so that the mixture can be sprayed onto the cutter head 230 through the nozzle 22. Finally, remove the threaded fastener 111 and take out the abutment 121 to remove the connector 12 fitted onto the cutter head 230, thereby preventing the connector 12 from affecting the operation of the cutter head 230.

[0080] Please see Figure 8 In some embodiments, nozzle 22 includes a spray channel 222. The spray channel 222 includes an inlet end 222a and an outlet end 222b. A mixture enters the spray channel 222 through the inlet end 222a and is sprayed toward the cutter head 230 through the outlet end 222b. The inlet end 222a is larger than the outlet end 222b to increase the pressure of the mixture sprayed toward the cutter head 230.

[0081] The larger inlet end 222a allows a large amount of mixture to enter the injection channel 222, while the smaller outlet end 222b allows the mixture ejected from the nozzle to have a higher pressure, thereby increasing the nozzle's ejection force. The mixture has a stronger ejection force on the cutter head 230, which improves the lubrication and cooling effect of the cutter head 230.

[0082] In some embodiments, the injection channel 222 includes a first channel 2221 and a second channel 2222. Viewed along the first direction Z, the outlet end 222b of the first channel 2221 and the outlet end 222b of the second channel 2222 are spaced apart, such that the mixture injected through the first channel 2221 and the mixture injected through the second channel 2222 can act on the cutter head 230 connected to the connecting shaft 220 with different extension lengths.

[0083] In some embodiments, the first direction Z is the vertical direction.

[0084] When the extension length of the connecting shaft 220 along the first direction Z is short, the cutter head 230 is positioned higher in the first direction Z. The cutter head 230 connected to the shorter connecting shaft 220 is cooled and lubricated by the mixture sprayed in the first channel 2221. When the extension length of the connecting shaft 220 along the first direction Z is long, the cutter head 230 is positioned lower in the first direction Z. The cutter head 230 connected to the longer connecting shaft 220 is cooled and lubricated by the mixture sprayed in the second channel 2222.

[0085] In some embodiments, the cutter head 230 and the connecting shaft 220 constitute a cutting tool. In different types of cutting tools, the length of the connecting shaft 220 along the first direction Z and the diameter of the cutter head 230 are different. The spray channel 222 can spray the mixture towards the cutter head 230 of different types to improve the versatility of the nozzle.

[0086] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
