Description

Technical Field

[0001] This invention relates to the field of irregular ceiling construction technology, specifically to a welding fixture for a prefabricated ceiling frame in a tall space. Background Technology

[0002] As people's living standards continue to improve, their demand for spiritual and cultural enrichment is also increasing, leading to a booming tourism industry. Consequently, tourist attractions with Chinese ancient cultural themes are proliferating, and more and more antique-style buildings are springing up. The beams, brackets, interior ceilings, coffered ceilings, and column heads feature meticulously crafted designs that seamlessly integrate composition and component shapes, showcasing exquisite artistry and rich colors. To preserve historical and traditional culture and achieve an antique-style wooden ceiling structure, modern decoration often utilizes transfer-printed wood grain aluminum panels for interior ceiling construction.

[0003] Tiered ceiling designs, similar to coffered ceilings, are commonly used in the decoration of large-space public buildings, and their framework structure is relatively unique. For example, the structure of a framework component is as follows: Figure 1 As shown in the middle right figure, in actual construction, it is necessary to first determine the required components of the same specifications and dimensions for the aluminum panel coffered ceiling and mass-produce them, and then number each component on each keel frame. Existing technology can be used to address this. Figure 1 When welding the keel components shown in the right figure, it is necessary to first determine the vertical position of each horizontal keel of different lengths, as well as the distance between them and adjacent horizontal keels, to determine the welding position. Spot welding is required first, and after spot welding, technicians need to promptly check the deviation of the frame. Only after no errors are found can the full welding stage begin. Furthermore, the position of each keel frame component must be measured and determined before welding, following the procedure of spot welding followed by full welding. Therefore, it is necessary to research a welding fixture for prefabricated ceiling keels in tall spaces. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide a welding fixture for a prefabricated ceiling frame in a large space, in order to solve the problems of complex position determination, time-consuming and labor-intensive welding process, difficulty in quality control, low production efficiency, and the need for frequent manual adjustment of the frame position in the existing antique-style coffered ceiling structure welding process.

[0005] To achieve the above objectives, the technical solution adopted by this invention is: a welding fixture for a high-ceiling prefabricated ceiling frame, characterized in that it includes a support frame, a gantry frame assembly, a mounting frame, a flipping assembly, and a welding machine. The gantry frame assembly is vertically arranged on the front side of the support frame and can reciprocate along the X-axis on the support frame. The support frame and the gantry frame assembly together form a clearance space for welding the gantry frame. The mounting frame is installed within this clearance space. The mounting frame includes a main frame, brackets, and locking components. The main frame is vertically fixed in the middle of the support frame, and multiple sets of brackets are vertically fixed on its left and right sides. The frame and each support have corresponding vertical main slots and horizontal support slots, with each support slot communicating with the main slot. A suction cup is installed within each support slot. The locking assembly includes a top block and a top spring. The top block is slidably installed within the support slot, and one end of the top spring is fixedly connected to the top block, while the other end is fixed to the inner end of the support slot. The flipping assembly is located on the support frame at the top of the main frame and is used to flip the keel frame. The welding machine is fixedly installed on the gantry assembly via an angle adjustment assembly, and under the action of the angle adjustment assembly, it can rotate and adjust at multiple angles on the gantry assembly to accurately locate the welding position of the keel components, thus facilitating the welding operation of the keel frame.

[0006] Furthermore, the main frame and the support have corresponding vertical main slots and horizontal support slots, with their openings facing the welding machine on the gantry assembly. Each support slot is connected to the main slot, thereby forming multiple cross-shaped passages. Locking components are provided in each support slot on both sides of the main slot.

[0007] Furthermore, a suction cup assembly is provided on the rear side of the support frame. The suction cup assembly includes a suction cup frame, an electric actuator, an air pump, and a suction cup. The suction cup frame is fixed to the rear side of the support frame and parallel to it. The air pump is fixed to the top of the suction cup frame. The distal end of the electric actuator is fixed to the suction cup frame, and the output end extends inward into the support groove and is fixedly connected to the suction cup.

[0008] Furthermore, the flipping assembly is disposed above the mounting frame. The flipping assembly includes a flipping motor base, a flipping motor, a fixing plate, and a telescopic rod. The flipping motor base is fixed to the front side wall of the support frame above the main frame. The flipping motor is fixed to the flipping motor base, and its output shaft passes vertically downward through the flipping motor base and is fixedly connected to the fixing plate. The lower end of the fixing plate is fixedly connected to the telescopic rod.

[0009] Furthermore, a flipping suction cup is fixedly connected to the bottom of the telescopic rod, or a flipping block adapted to the inner diameter of the vertical keel is fixedly connected to the lower end of the telescopic rod. The telescopic rod can control the flipping block to be inserted downwards into the vertical keel.

[0010] Furthermore, the gantry assembly includes a transverse movement component, a longitudinal movement component, and a lifting component. The longitudinal movement component includes a connecting frame, a bottom support, and a longitudinal movement motor. The connecting frame and the bottom support are arranged in parallel on the front side of the support frame. One end of the bottom support is slidably mounted on a fixed guide rail on the bottom plate of the support frame, and the other end is slidably fitted with a guide rod in a guide groove below the support frame.

[0011] Furthermore, a mounting groove is formed longitudinally on the base support, and a longitudinal guide rail is fixedly installed in the mounting groove. Correspondingly, a mounting groove is also formed in the connecting frame, and a lead screw is provided in the mounting groove on the connecting frame along its extension direction. The end of the lead screw away from the support frame extends out of the connecting frame and drives the longitudinal motor.

[0012] Furthermore, the connecting frame is provided with a transverse moving assembly at one end near the support frame. The transverse moving assembly includes a transverse moving motor, a transverse moving gear, a transverse moving rack, and a transverse moving slide rail. The transverse moving slide rail is fixed to the top of the support frame along the x-axis direction. The bottom of the connecting frame is slidably mounted on the support slide rail. The transverse moving motor is fixed to the top of the connecting frame, and its output end extends downward and is fixedly connected to the transverse moving gear. The transverse moving rack is fixed to the rear side wall of the support frame and meshes with the transverse moving gear.

[0013] Furthermore, the lifting assembly is disposed between the connecting frame and the base support. The lifting assembly includes a vertical rod, a vertical rack, a guide rod, a slider, a lifting motor, and a lifting gear. The upper and lower ends of the vertical rod are respectively installed with the lead screw in the connecting frame and the longitudinal guide rail in the base support.

[0014] Furthermore, the guide rod is arranged parallel to one side of the vertical rod, the slider is slidably mounted on the guide rod, the lifting motor is fixed on the slider, its output end extends forward, and the end is fixedly connected to the lifting gear. The vertical rack is fixedly mounted on the vertical rod along the z-axis and meshes with the lifting gear for transmission. A welding machine is also fixed on the side of the slider near the support frame through an angle adjustment component.

[0015] The beneficial effects of the above technical solution are as follows: This invention provides a welding fixture for a high-ceiling prefabricated keel frame. This fixture, through precise control of a horizontal movement motor, a vertical movement motor, and a lifting motor, enables the welding machine to move flexibly in three-dimensional space, thereby efficiently welding each joint of the keel frame. This automated welding method greatly improves production efficiency, reduces reliance on manual operation, and lowers labor costs.

[0016] By adjusting the angle adjustment component, the welding machine can perform adaptive welding for different welding gaps (such as side seam A, side seam B, and side seam C). In particular, the "bow" shaped welding method for side seams B and C not only ensures welding quality but also improves welding efficiency.

[0017] The introduction of the flipping assembly allows the keel frame to be flipped 90 degrees and 180 degrees during welding, enabling comprehensive welding of all sides of the keel frame. This design not only improves welding flexibility but also reduces the footprint of tooling, making the entire welding process more compact and efficient.

[0018] The use of a top block and a top spring enables the elastic pushing and unlocking of the keel frame. This mechanism allows the keel frame to maintain close contact during welding, ensuring welding quality; at the same time, it allows for easy unlocking when the keel frame needs to be moved or flipped, facilitating operation. This design not only improves the practicality of the tooling but also enhances its flexibility.

[0019] This invention enables the welding machine to move in three-dimensional space by driving, automating the welding operation, reducing manual intervention, and eliminating the need for frequent manual adjustments to the keel frame position. Simply placing horizontal keels of different sizes into the fixture is sufficient to achieve full welding operation, reducing manual operation, lowering the labor intensity of technicians, and effectively improving welding efficiency and accuracy.

Detailed Implementation

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0031] Example 1: This example aims to provide a welding fixture for a prefabricated ceiling frame in a large space, used to assist in the welding of the frame structure in an antique-style coffered ceiling structure. It aims to solve the problems of complex welding position determination, time-consuming and labor-intensive welding process, difficulty in quality control, and low production efficiency in the existing technology.

[0032] like Figure 1-9 As shown, the welding fixture for the prefabricated ceiling frame in this embodiment includes a support frame 1, a gantry assembly 2, a mounting bracket 3, a suction cup assembly 4, a flipping assembly 5, an angle adjustment assembly 9, and a welding machine 99, etc. Figure 1 As shown, in this embodiment, the gantry frame 2 is vertically arranged on the front side of the support frame 1, and its bottom is slidably installed on the base plate 7 of the support frame 11, and together with the support frame 1, it forms a clearance space for welding the gantry frame; the mounting frame 3 is fixedly installed inside the support frame 1, the gantry component 66 is fitted inside the mounting frame 3, and under the action of the flipping component 5, the gantry component 6 can be flipped 180 degrees in the clearance space.

[0033] Specifically, such as Figure 2-4As shown, in this embodiment, the mounting frame 3 includes a main frame, brackets, and locking components. The main frame is vertically fixed in the middle of the support frame 1, meaning that both the upper and lower ends of the main frame are welded and fixed to the inner wall of the support frame 1. Each bracket is symmetrically welded to both sides of the main frame. In this embodiment, the installation positions of each bracket and the main frame are adaptively preset according to the number and spacing of the horizontal keels 61 in the keel component 6. Figure 2 As shown, vertical main slots 31 and horizontal support slots 34 are correspondingly opened in the main frame and the support, with their opening direction facing the welding machine 99 on the gantry assembly 2, and each support slot 34 is connected to the main slot 31 to form multiple cross-shaped passages, and each support slot 34 on both sides of the main slot 31 is provided with a locking component.

[0034] like Figure 2 As shown, in this embodiment, the locking assembly includes a top block 32 and a top spring 33. The top block 32 is slidably installed in the support groove 34. One end of the top spring 33 is fixedly connected to the top block 32, and the other end is fixed to the end of the support groove 34 away from the main groove 31. When each individual horizontal keel 61 and vertical keel 62 is placed in the main groove 31 and the support groove 34 respectively, the top block 32 can press each horizontal keel 61 tightly against the vertical keel 62, facilitating welding by the welding machine 99 to weld its side positions. It should be noted that the elastic coefficient of the top spring 33 in each set of support grooves 34 from top to bottom is different, and they are adapted to the length of the horizontal keel 61 at the corresponding position. When horizontal keels 61 of different lengths and positions are placed in the support groove 34, the elastic pressing force of the top spring 33 with different elastic coefficients makes each horizontal keel 61 tightly contact the vertical keel 62 in the main groove 31.

[0035] Furthermore, after the horizontal keel 61 is placed in the support groove 34, in order to ensure that each horizontal keel 61 is in the same plane and to avoid some horizontal keels 61 protruding outward or some being placed too deep, in practical applications, the depth of each bracket of the mounting bracket 3 can be prefabricated to be slightly smaller than the width of the horizontal keel 61, or as described in this embodiment, a limiting groove 35 can be opened on the side wall of the top block 32 near the main groove 31, and the inner diameter of the limiting groove 35 can be matched with the inner diameter of the horizontal keel 61. When the technician places the horizontal keel 61 in the support groove 34, the position of each group of horizontal keels 61 can be restricted by the insertion of the horizontal keel 61 and the limiting groove 35, thereby further improving the welding accuracy and avoiding unevenness that would affect the welding quality.

[0036] like Figure 3As shown, a suction cup 41 is also provided in the support groove 34. In this embodiment, a suction cup assembly 4 is provided on the rear side of the support frame 1. The suction cup assembly 4 includes a suction cup frame 43, an electric push rod 44, an air pump 42, and a suction cup 41. The suction cup frame 43 is fixedly installed on the rear side of the support frame 1 and parallel to the mounting frame 3. The air pump 42 is fixed on the top of the suction cup frame 43 and is used to control the suction force of the suction cup 41. The distal end of the electric push rod 44 is fixed on the suction cup frame 43, and the output end extends inward into the support groove 34 and is fixedly connected to the suction cup 41. In practical applications, a suction cup 41 can be provided in each support groove 34, or the suction cup 41 structure can only be installed in the middle support groove 34. This saves costs on the one hand, and on the other hand, when the welding and fixing of each horizontal keel 61 and vertical keel 62 in the right support groove 34 is completed (i.e., as shown in the figure), it can be used to fix the suction cup 41. Figure 9 After welding at side a), the suction cup 41 is attracted to the horizontal keel 61 by the electric push rod 44 and extends forward to the outside of the support groove 34, so that the flipping assembly 5 can flip it over.

[0037] like Figure 3 and Figure 4 As shown, the flipping assembly 5 is positioned above the mounting frame 3. In this embodiment, the flipping assembly 5 includes a flipping motor base 51, a flipping motor 52, a fixing plate 53, and a telescopic rod 54. The flipping motor base 51 is fixed to the front side wall of the support frame 1 above the main frame. The flipping motor 52 is fixed to the flipping motor base 51, and its output shaft passes vertically downward through the flipping motor base 51 and is fixedly connected to the fixing plate 53. The lower end of the fixing plate 53 is fixedly connected to the telescopic rod 54, and the lower end of the telescopic rod 54 is fixedly connected to a flipping block that matches the inner diameter of the vertical keel 62. Under the action of the suction cup assembly 4, the vertical keel 62 extends forward from the front side of the main frame. When it reaches below the flipping block, the telescopic rod 54 controls the flipping block to be inserted downward into the vertical keel 62, thereby fixing the telescopic rod 54 and the vertical keel 62 together through a mechanical connection. Then, by driving the flipping motor 52 to rotate, the keel frame can be rotated 180 degrees around the telescopic rod 54 as the rotation axis.

[0038] In addition, it can also be like Figure 4 As shown, a flipping suction cup 55 is fixedly connected to the bottom of the telescopic rod 54. Under the action of the suction cup assembly 4, the vertical keel 62 extends forward beyond the front side of the main frame. When it reaches below the flipping suction cup 55, the suction force of the flipping suction cup 55 is controlled, thereby rotating the keel frame 180 degrees around the telescopic rod 54 as the rotation axis. The main purpose of the flipping assembly 5 in this embodiment is to facilitate the flipping operation of the keel frame. Since the joint point between the horizontal keel 61 and the vertical keel 62 requires full welding, controlling the rotation of the keel frame ensures that the welding machine 99 can easily perform full welding on all four sides of the keel frame, thereby greatly improving the welding quality and efficiency.

[0039] like Figure 1 and Figure 5 As shown, the welding machine 99 is fixedly mounted on the gantry assembly 2 via the angle adjustment component 9. The gantry assembly 2 can reciprocate along the X-axis on the support frame 1. In this embodiment, the gantry assembly 2 includes a transverse component, a longitudinal component, and a lifting component 8. The longitudinal component includes a connecting frame 20, a bottom support 26, and a longitudinal motor 25. The connecting frame 20 and the bottom support 26 are arranged parallel to each other on the front side of the support frame 1. One end of the bottom support 26 is slidably mounted on a fixed guide rail 28 on the bottom plate 7 of the support frame 1, and the other end is slidably fitted with a guide rod 292 in the guide groove 27 below the support frame 1. A mounting groove 261 is opened longitudinally on the bottom support 26, and a longitudinal guide rail 262 is fixedly installed in the mounting groove 261. Correspondingly, a mounting groove 261 is also opened in the connecting frame 20, and a lead screw is provided in the mounting groove 261 of the connecting frame 20 along its extension direction. The end of the lead screw away from the support frame 1 extends out of the connecting frame 20 and is connected to the longitudinal motor 25.

[0040] like Figure 5 As shown, the connecting frame 20 is provided with a transverse component at one end near the support frame 1. In this embodiment, the transverse component includes a transverse motor 21, a transverse gear 22, a transverse rack 23, and a transverse slide rail 24. The transverse slide rail 24 is fixed to the top of the support frame 1 along the x-axis direction. The bottom of the connecting frame 20 is slidably mounted on the support slide rail. The transverse motor 21 is fixed to the top of the connecting frame 20, and its output end extends downward and is fixedly connected to the transverse gear 22. The transverse rack 23 is fixed to the rear side wall of the support frame 1 and meshes with the transverse gear 22. Thus, when the transverse motor 21 is driven to work, the connecting frame 20, the lifting component 8, and the bottom support frame can be driven to slide back and forth along the x-axis direction through the meshing transmission of the transverse gear 22 and the transverse rack 23.

[0041] like Figure 6 and Figure 7 As shown, the lifting assembly 8 is disposed between the connecting frame 20 and the base support 26. In this embodiment, the lifting assembly 8 includes a vertical rod 29, a vertical rack 291, a guide rod 292, a slider 81, a lifting motor 82, and a lifting gear 83. The upper and lower ends of the vertical rod 29 are respectively installed with the lead screw in the connecting frame 20 and the longitudinal guide rail 262 in the base support 26. Thus, when the longitudinal motor 2525 is driven to rotate, the lifting assembly 8 can be synchronously driven to move back and forth along the extension direction of the longitudinal guide rail 262. That is, by controlling the forward and reverse rotation of the longitudinal motor 25, it can move closer to or away from the support frame 1.

[0042] Furthermore, the guide rod 292 is arranged parallel to one side of the vertical rod 29, the slider 81 is slidably mounted on the guide rod 292, the lifting motor 82 is fixed on the slider 81, its output end extends forward, and the end is fixedly connected to the lifting gear 83. The vertical rack is fixedly mounted on the vertical rod 29 along the z-axis direction and meshes with the lifting gear 83 for transmission. A welding machine 99 is also fixed on the side of the slider 81 near the support frame 1 through the angle adjustment component 9.

[0043] In this embodiment, the gantry assembly 2 is configured such that the welding machine 99 can reciprocate along the x-axis by driving the transverse motor 21, and can move the welding machine 99 closer to or further away from the support frame 1 by driving the longitudinal motor 25. By controlling the lifting motor 82, the welding machine 99 can easily perform welding operations on the horizontal keel 61 at different heights, thus making it more flexible.

[0044] like Figure 7 and Figure 8 As shown, in this embodiment, the angle adjustment component 9 includes a mounting plate 90, a drive motor 91, a swing motor 92, a bearing seat 94, a ring frame 95, a swing frame 97, a fixed seat 98, and a worm gear 93 structure. The mounting plate 90 is fixed to the slider 81 on the side away from the vertical rack by bolts. Bearing seats 94 are fixed on the mounting plate 90 at intervals. The worm gear 93 is rotatably mounted between adjacent bearing seats 94, with both ends extending outward. One end is connected to the drive motor 91 for transmission, and the other end is connected to the swing motor 92 through a bushing. Therefore, by controlling the operation of the drive motor, the rotation of the worm gear can be driven synchronously. The ring frame 95 is mounted above the worm gear 93, with one side of its bottom fixedly fitted on the drive shaft of the swing motor 92, and the other side connected to the drive motor 91 shaft through a bearing.

[0045] The worm gear is located inside the ring frame 95 and meshes with the worm 93. A rotating shaft is fixedly installed inside the worm gear 96. Both ends of the rotating shaft pass through the ring frame 95 and are fixedly connected to the swing frame 97. The fixed seat 98 is fixedly installed on the top of the swing frame 97. The welding machine 99 is fixedly installed inside the U-shaped fixed seat 98, and the welding rod at the output end of the welding machine 99 faces the support frame 1.

[0046] In this embodiment, the angle adjustment component 9 is configured such that when the drive motor 91 is working, it drives the worm 93 to rotate through its transmission connection with the worm gear 93. The worm wheel 96, through its meshing with the worm gear 93, rotates around its axis, thereby causing the welding machine to swing up and down around this axis via the swing frame 97. When the swing motor 92 is working, the worm gear 93 remains stationary, and the ring frame 95 drives the worm wheel, swing frame 97, and welding machine 99 to rotate around the worm gear 93. In this embodiment, the coordinated operation of the drive motor 91 and the swing motor 92 enables precise control of the welding machine 99, allowing for multi-angle welding operations. This allows the machine to swing at predetermined angles and positions, ensuring the welding rod accurately reaches the welding position, reducing errors during welding, and improving welding accuracy and consistency. Furthermore, the transmission mechanism of the worm gear 93 structure has self-locking properties, which can prevent the welding machine 99 from accidentally swinging due to external interference during welding, thus ensuring the stability of the welding process and improving welding quality.

[0047] Working principle explanation; The welding fixture for the prefabricated ceiling frame in high-ceiling spaces provided in this embodiment, in actual application, such as... Figure 9 As shown, the vertical keel 62 is placed in the main groove 31, and each horizontal keel 61 is placed in the support groove 34 on the right side of the flipping assembly 5. The top block 32 makes each component press tightly against the vertical keel 62, thereby welding the a-side of the butt joint between each horizontal keel 61 and the vertical keel 62. The process includes the following steps: driving the horizontal movement motor 21 to move the welding machine 99 to the right to correspond with the uppermost horizontal keel 61, and then driving the vertical movement motor 25 to move the welding machine 99 toward the keel frame. After it reaches the position of the uppermost horizontal keel 61, the welding machine 99 contacts the a-side joint and starts working. By driving the lifting motor 82, it controls the welding machine 99 to perform welding operations on the a-side joint from top to bottom.

[0048] After completion, the longitudinal motor 25 is driven to move the welding machine 99 away from the keel frame. Then, the suction cup 41 in the support groove 34 and the electric push rod 44 push the keel frame structure that has been welded on one side to move outward. The flipping component 5 is fixedly connected to the keel frame, the electric push rod 44 retracts, and the flipping motor 52 drives the keel frame to rotate 90 degrees to be perpendicular to the support frame 1. Then, the transverse motor 21 is driven to move the welding machine 99 to one side of the keel frame. By adjusting the angle adjustment component 9, the welding rod of the welding machine 99 is made to point downward. When the welding machine 99 is tilted to match the top gap of each horizontal keel 61, the welding work on the b side seam begins. Through the cooperation of the horizontal movement motor 21 and the lifting motor 82, the welding machine 99 first welds the b side seam from top to bottom in an "arch" shape. Then, it is reset and the angle adjustment component 9 is adjusted so that the welding rod of the welding machine 99 tilts upward to match the bottom gap of each horizontal keel 61, and the welding work on the c side seam begins. Through the cooperation of the horizontal movement motor 21 and the lifting motor 82, the welding machine 99 welds the c side seam from top to bottom in an "arch" shape.

[0049] After completion, the keel frame is rotated 90 degrees by the drive motor 52 to the support groove 34 on the left side of the flip assembly 5. The top block 32 presses each component tightly against the vertical keel 62, thereby welding the butt joint d side of each horizontal keel 61 and vertical keel 62. First, adjust the welding rod of the welding machine 99 to be perpendicular to it, and then repeat the welding operation of the a side joint as described above. It should be noted that when placing the horizontal keel 61, the top block 32 and the top spring 33 can be manually pulled to achieve elastic pushing and unlocking of the keel frame. After the keel frame is flipped 180 degrees and returned to the support groove 34 on the left side, the suction cup 41 and the electric push rod 44 in the support groove 34 on the left side will attract the keel frame. To prevent the electric push rod 44 from pushing outward and causing the keel frame to rotate or tilt outward, a push parallel to the keel frame can be manually provided during this process to make it enter the support groove 34 on the other side.

[0050] The high-ceiling prefabricated keel frame welding fixture provided in this embodiment realizes the three-dimensional spatial movement of the welding machine through drive, automates the welding operation, reduces manual intervention, and improves welding efficiency and accuracy. It eliminates the need for frequent manual adjustment of the keel frame position. Through precise positioning and clamping devices, it ensures the stability and accuracy of the keel frame during the welding process, reduces manual operation, and lowers the labor intensity of technicians.

[0051] The embodiments of the present invention described above do not constitute a limitation on the scope of protection of the present invention. The basic concept of the present invention is to realize the three-dimensional spatial movement of the welding machine through drive, automatically complete the welding operation, reduce manual intervention, and eliminate the need for frequent manual adjustment of the keel frame position. Full welding operation can be achieved simply by placing horizontal keels of different sizes into the fixture, reducing manual operation, lowering the labor intensity of technicians, and effectively improving welding efficiency and accuracy. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
