Description

Technical Field

[0001] The present invention relates to the field of intelligent manufacturing technology, and in particular to an extra-long bolt chamfering device. Background Art

[0002] Extra-long bolts are a type of connecting parts whose length far exceeds that of conventional bolts. They are widely used in high-end industries such as wind turbines. In the processing of extra-long bolts, in order to improve the convenience of extra-long bolts during assembly and optimize their connection performance, it is necessary to chamfer the ends of the extra-long bolts.

[0003] The existing technology generally adopts a conventional processing method when performing intelligent manufacturing chamfering processing on extra-long bolts used in high-end industries such as wind turbines, that is, clamping one end of the extra-long bolt and chamfering the other end. During the processing, the cutting blade usually penetrates from the side of the extra-long bolt, and controls the processing depth of the cutting blade in a direction perpendicular to the central axis of the extra-long bolt to perform the cutting operation. Since the extra-long bolt itself is relatively long, under this conventional processing method, the cutting blade will exert a large extrusion pressure on the extra-long bolt from the side during the cutting process. Since the distance between the clamping position and the cutting operation position of the extra-long bolt is too far, and the force is vertical, the extra-long bolt is subjected to excessive lateral extrusion pressure, and the longer rod body is prone to deformation, which will not only affect the assembly accuracy of the extra-long bolt during subsequent use, but also reduce the service life of the extra-long bolt.

[0004] Therefore, an extra-long bolt chamfering device is proposed to solve some problems existing in the above-mentioned prior art. Summary of the Invention

In the present invention, the extra-long bolts are fed into the clamping mechanism one by one through the step-type bar material conveying mechanism, and the upper and lower parts of the clamping tube are firmly clamped in the middle position and rotated. The second hydraulic push rods in the depth mechanism on the left and right sides control the tool holder to drive the cutting blade to adjust the cutting depth along the central axis direction of the extra-long bolt, thereby realizing intelligent chamfering of the extra-long bolts.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0045] Example: This example provides an extra-long bolt chamfering device, see Figure 1 - Figure 11Specifically, it includes a base 1, the end of the base 1 is provided with a clamping mechanism, and the clamping mechanism includes a first bracket 2 fixed to the inner side of the end position of the base 1, and a vertically arranged lower lifting platform 201 is slidably inserted on the first bracket 2, a second bracket 202 is fixed on the base 1, and an upper lifting platform 203 vertically arranged just above the lower lifting platform 201 is slidably inserted in the second bracket 202, a first hydraulic push rod 204 is fixed in both the first bracket 2 and the second bracket 202, and the telescopic end of the first hydraulic push rod 204 located in the first bracket 2 The telescopic end of the first hydraulic push rod 204 located in the second bracket 202 is fixedly connected to the upper lifting platform 203. By starting the upper and lower first hydraulic push rods 204, the lower lifting platform 201 and the upper lifting platform 203 can be controlled to rise and fall respectively. A connecting seat 205 is provided between the lower lifting platform 201 and the upper lifting platform 203, and a horizontally arranged clamping tube 206 is rotated in the middle position of the connecting seat 205. The connecting seat 205 and the clamping tube 206 are equally divided into upper and lower parts from the middle position. The connecting seat 205 The upper and lower parts of 05 are firmly connected to the upper lifting platform 203 and the lower lifting platform 201 respectively. The lower part of the clamping tube 206 is stably rotated and installed in the lower part of the connecting seat 205 through a semicircular guide rail. The upper part of the clamping tube 206 is stably rotated and installed in the upper part of the connecting seat 205 through a semicircular guide rail. The upper part of the clamping tube 206 is stably rotated and installed in the upper part of the connecting seat 205 through a semicircular guide rail. The upper and lower semicircular guide rails can form a complete circular guide rail after being spliced ​​together. After the upper and lower parts of the clamping tube 206 are spliced ​​together, they can stably rotate in the connecting seat 205 after the upper and lower parts are spliced ​​together. A driving mechanism is installed on the lower lifting platform 201. The first transmission mechanism for rotating the clamping tube 206, two left-right symmetrically arranged depth mechanisms are installed on the base 1, and the depth mechanism includes a laterally arranged second hydraulic push rod 4, a slide 401 is fixed on the telescopic end of the second hydraulic push rod 4, and a tool holder 5 is installed in the slide 401, and two symmetrical and inclined cutting blades 6 are installed on the tool holder 5, and the symmetry axes of the two cutting blades 6 are in the same straight line with the central axis of the clamping tube 206, a material collection box 8 is provided on one side of the clamping mechanism, and a step-type bar conveying mechanism is provided on the other side of the clamping mechanism.

[0046] During the operation of the device, relevant staff use the device to perform intelligent chamfering on extra-long bolts. Extra-long bolts are mainly used in high-tech industries such as wind power generation, construction, bridge construction, mechanical equipment, and marine engineering. First, the extra-long bolts to be chamfered are transported one by one to the clamping mechanism accurately and stably under the transportation of the step-by-step bar conveying mechanism, and then the clamping mechanism is automatically started, and the lower lifting platform 201 and the upper lifting platform 203 are driven to move synchronously to the middle position through the synchronous start of the upper and lower first hydraulic push rods 204. The lower lifting platform 201 moves upward and the upper lifting platform 203 moves downward, and finally the upper and lower parts of the connecting seat 205 respectively drive the upper and lower parts of the clamping tube 206 to approach each other, and the extra-long bolts are chamfered. The bolt is stably clamped in the upper and lower parts of the closed clamping tube 206, and then the second hydraulic push rod 4 in the depth mechanism symmetrically arranged on the left and right sides is started synchronously, controlling the cutting blades 6 installed on the left and right tool holders 5 to gradually approach the left and right ends of the extra-long bolt. During this process, the clamping tube 206 is driven to rotate by the first transmission mechanism, driving the extra-long bolt to rotate at high speed. During the rotation process, the cutting blades 6 on the left and right sides move along the central axis of the extra-long bolt, so that the cutting blades 6 gradually approach the two ends of the extra-long bolt and go deeper, thereby realizing the chamfering of the two ends of the extra-long bolt. By controlling the moving position of the cutting blades 6 on the left and right ends, the depth of the cutting blade 6 cutting into the extra-long bolt is adjusted, thereby realizing the control of the chamfer position size.

[0047] In the process of using the cutting blade 6 to cut and chamfer the extra-long bolt, the two cutting blades 6 on the same side are symmetrically arranged up and down and are in the same plane with the central axis of the extra-long bolt. This allows the cutting blade 6 to cut and chamfer the extra-long bolt from both sides at the same time during the gradual deepening process. Cutting blades 6 are provided at both ends of the extra-long bolt for cutting and chamfering. The force applied at both ends simultaneously can not only ensure the force balance during cutting, but also chamfer both ends of the extra-long bolt at the same time, which can effectively improve the efficiency of chamfering the extra-long bolt. During the cutting and chamfering process, the cutting blade 6 on each side will go deeper laterally along the central axis of the extra-long bolt. This makes the force direction of the cutting blade 6 when cutting the chamfer of the extra-long bolt parallel to the central axis of the extra-long bolt. Compared with the operation of chamfering the extra-long bolt from the side by a lathe in the prior art, the bending deformation of the extra-long bolt due to excessive side extrusion pressure during the cutting and chamfering process can be effectively reduced, and the stability and accuracy of the device in chamfering the extra-long bolt can be improved to a certain extent.

[0048] After the chamfering is completed, the upper and lower first hydraulic push rods 204 start in reverse, driving the lower lifting platform 201 and the upper lifting platform 203 to drive the upper and lower parts of the connecting seat 205 and the upper and lower parts of the clamping tube 206 to separate, loosening the clamping of the extra-long bolt, and then the extra-long bolt that has been chamfered is sent into the collecting box 8 through the step-by-step bar conveying mechanism, and the next extra-long bolt to be chamfered is sent into the clamping mechanism, ready for the chamfering of the next extra-long bolt. After the clamping tube 206 is driven to rotate and stop, the position of the clamping tube 206 will be precisely controlled. After the rotation cutting of the extra-long bolt is completed, the upper and lower parts of the clamping tube 206 will respectively and accurately stay in the upper and lower parts of the connecting seat 205, which can effectively ensure that the clamping mechanism can smoothly and stably loosen the clamping operation of the extra-long bolt, thereby ensuring the efficient operation of the device cycle.

[0049] In the specific implementation process, Figure 3 As shown, one side of the interior of the clamping tube 206 is equipped with an internal thread that is adapted to the outer thread of the extra-long bolt, and the other side of the interior of the clamping tube 206 is set to a smooth surface. During the operation of the device, the internal thread and the smooth surface are respectively set inside the left and right ends of the clamping tube 206. When the upper and lower parts of the clamping tube 206 are used to clamp the extra-long bolt, the clamping tube 206 is clamped at the connection position between the thread and the smooth surface on the extra-long bolt, and the internal thread in the clamping tube 206 is engaged with the thread of the outer thread of the extra-long bolt, and the smooth surface in the clamping tube 206 clamps the smooth surface on the extra-long bolt. In the process of the clamping mechanism controlling the upper and lower parts of the clamping tube 206 to close and clamp the extra-long bolt, the internal thread inside the clamping tube 206 and the external thread outside the extra-long bolt are engaged with each other, so that the extra-long bolt cannot move left and right after being clamped. The large-area contact friction when the smooth surface inside the clamping tube 206 clamps the smooth surface on the extra-long bolt makes it impossible for the extra-long bolt to rotate inside the clamping tube 206 after being clamped. With the cooperation of each other, the extra-long bolt can be stably driven to rotate and maintain a stable position during the cutting process, which is beneficial to improving the stability of the extra-long bolt when being chamfered.

[0050] In the specific implementation process, Figure 3 and Figure 10As shown, the upper lifting platform 203 and the lower lifting platform 201 are provided with slots adapted to the upper and lower parts of the connecting seat 205, and the upper and lower parts of the connecting seat 205 are respectively clamped in the slots opened on the upper lifting platform 203 and the lower lifting platform 201. The slots opened on the upper lifting platform 203 and the lower lifting platform 201 are both equipped with electromagnets. The connecting seat 205 is made of magnetic conductive materials such as high-strength steel. During the operation of the device, the outer dimensions of the upper and lower parts of the connecting seat 205 are adapted to the dimensions of the slots, which allows the upper and lower parts of the connecting seat 205 to be stably clamped in the slots opened on the lower lifting platform 201 and the upper lifting platform 203, and the connecting seat 205 and the clamping tube 206 can be easily disassembled, so that the device can be adapted to cut extra-long bolts of different sizes, which is beneficial to improving the applicability of the device.

[0051] During the operation of the device, when the clamping mechanism is used to clamp the extra-long bolts, the electromagnets installed in the lower lifting platform 201 and the upper lifting platform 203 will be powered on and started. After the electromagnet in the lower lifting platform 201 is started, a high-strength magnetic connection will be performed to the lower part of the connecting seat 205 embedded in the upper slot. After the electromagnet in the upper lifting platform 203 is started, a high-strength magnetic connection will be performed to the upper part of the connecting seat 205 embedded in the upper slot. As a result, the upper and lower parts of the connecting seat 205 can be more stably connected to the upper lifting platform 203 and the lower lifting platform 201 during the use of the device, which is beneficial to ensuring the stability of the device during operation.

[0052] In the specific implementation process, Figure 2 and Figure 3As shown, the first transmission mechanism includes a first gear 3 fixedly mounted at the end position of the clamping tube 206, and the first gear 3 is divided into an upper and lower part following the clamping tube 206, a second gear 301 meshing with the first gear 3 is rotated on the lower lifting platform 201, a vertically arranged first shaft cylinder 302 is rotated on the lower lifting platform 201, and a first bevel gear assembly 303 is transmission-connected between the first shaft cylinder 302 and the second gear 301, a first spline shaft 304 slidingly inserted in the first shaft cylinder 302 is rotated on the first bracket 2, and a servo motor for driving the first spline shaft 304 to rotate is fixed in the first bracket 2. During the operation of the device, when the clamping mechanism clamps the extra-long bolt, the servo motor is powered on and started, driving the servo motor transmission-connected to its drive shaft The first spline shaft 304 rotates, and then the first spline shaft 304 drives the first shaft cylinder 302 to rotate. The first bevel gear assembly 303 is composed of two mutually perpendicular bevel gears meshing. Through the transmission connection of the first bevel gear assembly 303, the rotational power on the first shaft cylinder 302 is transmitted to the second gear 301, and then with the help of the meshing of the second gear 301 and the first gear 3, the clamping tube 206 is driven to rotate, providing power for the rotation of the over-long bolt. In the first transmission mechanism, the first shaft cylinder 302 is slidably sleeved on the outside of the second gear 301. During the clamping start-up process, the first shaft cylinder 302 will move up and down synchronously with the lower lifting platform 201, which can ensure that the clamping tube 206 is stably driven to rotate during the up and down adjustment of the lower lifting platform 201.

[0053] In the specific implementation process, Figure 4 and Figure 10 As shown, the slide 401 is slidably mounted on the base 1, a third hydraulic push rod 402 is fixed to the bottom of the slide 401, the tool holder 5 is slidably mounted on the slide 401 in the vertical direction, and the telescopic end of the third hydraulic push rod 402 is fixedly connected to the tool holder 5. During the operation of the device, the slide 401 is slidably mounted on the base 1, and its sliding direction is consistent with the moving direction of the telescopic end of the second hydraulic push rod 4, and is consistent with the opposite direction of the cutting blade 6 penetrating into the extra-long bolt during cutting and chamfering. The sliding of the slide 401 guides the penetration of the cutting blade 6, which is conducive to ensuring the stability of the device when chamfering the extra-long bolt. At the same time, By sliding the tool holder 5 on the slide 401 and pushing and controlling it with the help of the third hydraulic push rod 402 fixed at the bottom of the slide 401, the tool holder 5 can be raised and lowered, which is convenient for synchronously adjusting the positions of the upper and lower cutting blades 6 according to the size of the extra-long bolts clamped in the clamping mechanism, so that the upper and lower cutting blades 6 can be adapted to cut into the edge positions of extra-long bolts of different sizes. Combined with the flexible replacement of the connecting seat 205 and the clamping tube 206, the device can chamfer extra-long bolts of different sizes, which to a certain extent improves the scope of application and flexibility of use of the device.

[0054] In the specific implementation process, Figure 4 - Figure 6 As shown, the tool holder 5 includes a main seat body 501 that is slidably connected to the slide 401, and a shaft seat 502 that is symmetrically arranged up and down is fixed to the side of the main seat body 501 close to the clamping mechanism, and a fan-shaped plate 503 is rotatably installed in each shaft seat 502, and the cutting blade 6 is fixed on the fan-shaped plate 503, and an arc-shaped tooth groove 504 is opened around the outer side of the fan plate 503, and a third gear 505 that is meshed with the arc-shaped tooth groove 504 is rotatably installed in the main seat body 501, and a vertically arranged second shaft cylinder 506 is rotatably installed in the main seat body 501, and a worm gear assembly 507 is transmission-connected between the second shaft cylinder 506 and the two third gears 505, and a second transmission mechanism is installed on the slide 401. During the operation of the device, the cutting blade 6 used for cutting and chamfering the extra-long bolts can be adjusted in angle, which enables the device to chamfer the two ends of the extra-long bolts at different angles according to actual needs.

[0055] When the angle of the cutting blade 6 needs to be adjusted, the second transmission mechanism is started to drive the second shaft cylinder 506 to rotate. The worm gear assembly 507 is composed of a worm wheel fixed on the third gear 505 and a worm fixed on the second shaft cylinder 506. The worm wheel and the worm are meshed with each other. When the second shaft cylinder 506 rotates, the third gear 505 is driven to rotate by means of the transmission connection of the worm gear assembly 507. Then, with the meshing of the third gear 505 and the arc-shaped tooth groove 504, the sector plate 503 can be driven to rotate in the shaft seat 502, thereby adjusting the inclination angle of the cutting blade 6 fixed on the sector plate 503. The teeth of the worm wheel and the worm in the upper and lower worm gear assemblies 507 are connected. The directions are opposite, which makes the second shaft cylinder 506 driven to rotate, and through the transmission connection of the upper and lower worm gear assemblies 507, it will drive the upper and lower third gears 505 to rotate synchronously relative to each other, and then the upper and lower fan-shaped plates 503 respectively drive the upper and lower cutting blades 6 to rotate synchronously relative to each other to adjust the angle, which makes the upper and lower cutting blades 6 always in a symmetrical state. During the chamfering process, the upper and lower cutting blades 6 are V-shaped and engaged with the outside of the end of the extra-long bolt, which can perform more stable and efficient chamfering processing. By synchronously adjusting the inclination angles of the upper and lower cutting blades 6, the flexibility of the device in chamfering extra-long bolts can be further improved.

[0056] During the process of adjusting the angle of the cutting blade 6 , the self-locking property of the worm gear in the worm gear assembly 507 when the worm gear is engaged can ensure the structural stability of the cutting blade 6 after the angle adjustment.

[0057] In the specific implementation process, Figure 6 and Figure 7As shown, the second transmission mechanism includes a second spline shaft 7 slidably inserted in the second shaft cylinder 506, and the bottom end of the second spline shaft 7 is rotatably connected to the slide 401, and a third spline shaft 701 is rotatably installed on the base 1 and is laterally arranged below the slide 401. The third spline shaft 701 is parallel to the sliding track of the slide 401, and a sliding sleeve 702 is rotatably provided on the slide 401 and is arranged on the outer side of the third spline shaft 701, and a second bevel gear assembly 703 is transmission-connected between the sleeve 702 and the lower end of the second spline shaft 7, and a servo motor for driving the third spline shaft 701 to rotate is installed on the base 1.

[0058] When the device is running, when the second transmission mechanism is used to drive the second shaft cylinder 506 to rotate, in the process of adjusting the tilt angle of the cutting blade 6, the servo motor is powered on and started, driving the third spline shaft 701 fixedly connected to its drive shaft to rotate. During the rotation of the third spline shaft 701, it will drive the shaft sleeve 702 sleeved on the outside thereof to rotate synchronously. The second bevel gear assembly 703 is composed of two mutually perpendicular bevel gears. After the shaft sleeve 702 is driven to rotate, it will drive the second spline shaft 7 to rotate through the transmission connection of the second bevel gear assembly 703, and then drive the second shaft cylinder 506 sleeved on the outside of the second spline shaft 7 to rotate, providing power for the angle adjustment of the cutting blade 6. The second shaft cylinder 506 is slidably mounted on the outside of the second spline shaft 7. The second shaft cylinder 506 will follow the up and down movement of the tool holder 5 and move synchronously on the outside of the second spline shaft 7, so that the up and down movement of the tool holder 5 will not affect the transmission connection between the second spline shaft 7 and the second shaft cylinder 506. Similarly, the sleeve 702 is slidably mounted on the third spline shaft 701. The sleeve 702 will follow the left and right movement of the slide 401 and move synchronously on the outside of the third spline shaft 701, so that the left and right movement of the tool holder 5 will not affect the transmission connection between the second spline shaft 7 and the third spline shaft 701, so that the servo motor can provide stable power for the angle adjustment of the cutting blade 6.

[0059] In the specific implementation process, Figure 8 、 Figure 9 and Figure 11As shown, the step-by-step bar material conveying mechanism includes a frame 9 fixed on the base 1, and two first pallets 901 arranged side by side are fixed on the frame 9, and the top of the first pallet 901 is provided with evenly distributed first grooves 902, and two parallel swing arms 904 are rotated in the frame 9, and the end positions of the two swing arms 904 are rotated together and connected to a connecting frame 905, and a second pallet 906 located between the two first pallets 901 is fixed on the top of the connecting frame 905, and second grooves 907 corresponding to the numerous first grooves 902 are evenly provided on the top of the second pallet 906, and a servo motor for driving the swing arm 904 to rotate and swing is installed in the frame 9, and a guide plate 909 extending to the top of the aggregate box 8 is fixed at the end position of the first pallet 901, and the top of the guide plate 909 is close to the side of the aggregate box 8 and is set to a downward inclined structure.

[0060] During the operation of the device, the step-by-step bar conveying mechanism is started to convey the extra-long bolts one by one. The servo motor is powered on and started, driving the swing arm 904 connected to its drive shaft to rotate. Through the connection of the swing arm 904, the connecting frame 905 can be driven to swing back and forth, thereby driving the second support plate 906 to swing back and forth between the left and right first support plates 901. The second groove 907 provided on the second support plate 906 is adapted to the first groove 902 provided on the first support plate 901. The extra-long bolts are placed horizontally in the corresponding first grooves 902 provided on the left and right first support plates 901. When the second support plate 906 swings forward, the second support plate 906 experiences a trajectory of rising and then falling. The second groove 907 provided on the second support plate 906 receives the extra-long bolts, and then places the extra-long bolts in the first pair of first grooves 902. The second support plate 906 is cyclically swung to control the progressive delivery of the extra-long bolts. The extra-long bolts are transported to the clamping mechanism in an orderly manner through the step-by-step bar conveying mechanism, and are automatically transported to the guide plate 909 after chamfering, so that the extra-long bolts after chamfering can slide along the inclined surface at the top of the guide plate 909 into the collecting box 8, which is conducive to realizing the automatic loading and unloading operation of the chamfering of the extra-long bolts, and is convenient for realizing intelligent processing, which improves the efficiency of the device for chamfering the extra-long bolts to a certain extent.

[0061] In the specific implementation process, Figure 8 and Figure 11As shown, a first magnet 903 corresponding to the first groove 902 is fixed on the first support plate 901, and a second magnet 908 corresponding to the second groove 907 is fixed on the second support plate 906. During the operation of the device, each first groove 902 is corresponding to a first magnet 903, and each second groove 907 is corresponding to a second magnet 908. When the step-by-step bar conveying mechanism is used to convey the extra-long bolts, the extra-long bolts are placed in the symmetrical first groove 902 or the second groove 907. With the help of the magnetic attraction of the first magnet 903 and the second magnet 908 on the extra-long bolts, the extra-long bolts can stay stably in the first groove 902 or the second groove 907. The extra-long bolts are positioned during the conveying process, which can effectively improve the stability of the extra-long bolts during the step-by-step conveying process.

[0062] In the specific implementation process, Figure 8 and Figure 11 As shown, the bottom of the aggregate box 8 is set to a hollow structure, a box frame 801 is fixed on the outside of the base 1, and a sliding frame 802 is provided in the box frame 801, and a pull rod 803 is hinged between the bracket 802 and the connecting frame 905, and the aggregate box 8 is placed in the bracket 802. During the operation of the device, the extra-long bolts after chamfering are finally transported to the aggregate box 8. When the extra-long bolts are transported by means of the step-by-step bar conveying mechanism, the connecting frame 905 swings back and forth, and through the connection of the pull rod 803, it can drive the bracket 802 to swing back and forth in the box frame 801. Since the aggregate box 8 is placed in the bracket 802, the swinging of the bracket 802 back and forth will drive the aggregate box 8 to swing back and forth. Through active shaking, the metal debris attached to the extra-long bolts can be shaken off, so that the metal debris is finally discharged through the hollow structure at the bottom of the aggregate box 8, which is convenient for subsequent processing of the extra-long bolts after chamfering.

[0063] Specifically, the working principle and operation method of the present invention are as follows:

[0064] After the device is started, the extra-long bolts are transported one by one to the clamping mechanism through the step-by-step bar conveying mechanism. The extra-long bolts are firmly clamped by closing the upper and lower parts of the connecting seat 205 and the clamping tube 206 in the clamping mechanism. The clamping tube 206 is driven by the first transmission mechanism to drive the extra-long bolt to rotate at high speed. Then, the second hydraulic push rods 4 in the left and right side depth mechanisms are started to control the cutting blades 6 installed on the left and right side tool holders 5 to gradually deepen along the central axis direction of the extra-long bolt. With the help of the cutting blades 6 symmetrically arranged on the left and right sides, both ends of the extra-long bolt are cut at the same time. Chamfering operation: After chamfering, the extra-long bolts are transported into the aggregate box 8 by the step-by-step bar conveying mechanism. Synchronously, with the help of the connection of the pull rod 803, when the step-by-step bar conveying mechanism is started, it will pull the bracket 802 to drive the aggregate box 8 to swing back and forth, and quickly screen out the metal debris adhering to the extra-long bolts. During the chamfering process, the second transmission mechanism can drive the two cutting blades 6 symmetrically arranged on the same side to rotate synchronously relative to each other. The inclination angle of the cutting blade 6 can be adjusted according to actual needs, and the chamfering angle on the extra-long bolt can be flexibly adjusted.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
