Description

Technical Field

[0001] This invention relates to the field of rotor processing equipment technology, specifically to a motor rotor processing technology and processing equipment. Background Technology

[0002] During the machining of automotive motor rotors, the outer shell surface of the rotor needs to be machined using a drill bit. During this process, metal filings frequently fly off. In continuous production, the continuous machining process generates metal filings, and the accumulation and flying of these filings can easily contaminate the machining table and affect subsequent machining operations. Current rotor machining processes typically use negative pressure suction cylinders to absorb the flying metal filings, concentrating them in a designated area for centralized processing. Furthermore, automotive motor rotors are large, the machining time is long, and a large amount of metal filings are generated. Drill bit replacements are also frequent. If the metal filings are not handled properly during machining, they can easily clog the drill bit and cause abnormalities on the machined surface.

[0003] However, in existing technologies, when using a negative pressure suction cylinder to suck up flying iron filings, the drill bit is inserted into the suction cylinder, and the negative pressure suction cylinder and the drill bit are coaxial. This causes the drill bit to easily come into contact with the rotor shaft when it approaches the machining surface of the rotor. The rotor shaft will collide with the negative pressure suction cylinder, and the negative pressure suction cylinder will affect the machining position of the drill bit. Furthermore, if the machining drill bit rotates at a high speed, the flying speed of the generated chips will also be high. If the negative pressure suction cylinder cannot be physically close enough, the negative pressure suction will not be able to suck the chips into the negative pressure suction cylinder in time. Therefore, a motor rotor machining process and machining device are proposed. Summary of the Invention

[0004] The purpose of this invention is to provide a motor rotor machining process and machining apparatus to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a motor rotor processing technology, comprising the following steps:

[0006] S1. After the initial machining of the motor rotor is completed, the motor rotor is installed on the rotating base and fixed by the rotating base. The machining drill bit is then passed through the machining hole of the machining device.

[0007] S2. After the drill bit is positioned in the processing hole of the adsorption device, fix the position of the drill bit and the motor rotor, and synchronously adjust the adsorption device and the drill bit to the processing end face of the motor rotor.

[0008] S3. Surround the central axis of the motor rotor with the external shielding of the adsorption device to shield the machined surface of the motor rotor and the central axis.

[0009] S4. After the shielding is completed, the machining drill bit is started to contact the machining end face of the motor rotor. When iron filings are generated and splashed, the adsorption device is started to simultaneously adsorb the splashed iron filings into the collection device.

[0010] The present invention also provides a motor rotor processing device. The adsorption device in S1 includes a front and rear moving plate. A suction cylinder is installed on the outside of the front and rear moving plate by screws. A moving structure is installed on the outside of the front and rear moving plate. The side of the suction cylinder near the rotor is a blade-shaped inclined surface. Multiple suction holes are opened on the blade-shaped inclined surface of the suction cylinder. A suction connecting cylinder is connected to one side of the suction cylinder. The suction connecting cylinder is connected to an external suction pump.

[0011] An elastic flexible plate is fixedly connected to the outside of the suction cylinder.

A blowing structure is installed on the outside of the elastic flexible plate.

[0012] Preferably, the blowing structure includes an airbag, which is integrally formed on the outside of the elastic flexible plate.

[0013] Preferably, the interior of the elastic flexible plate has multiple central soft bladders integrally formed, the interior of the central soft bladders is filled with electrorheological fluid, the central soft bladders surround the air supply pipe, and an adjustment plate is fixedly connected to the outside of the air supply pipe, the adjustment plate penetrating the outer wall of the air bladder.

[0014] Preferably, the central soft capsule is integrally formed with side strip-shaped fixation capsules on its exterior, the interior of which is filled with electrorheological fluid, and the number of side strip-shaped fixation capsules is not less than one.

[0015] Preferably, both the central soft capsule and the side strip-shaped fixation capsule are internally connected to multiple electromagnetic coils, and the electrorheological fluid inside the central soft capsule and the side strip-shaped fixation capsule and the electromagnetic coils are connected to an external power source through wires.

[0016] Preferably, multiple air supply ducts are arranged horizontally on the outside of the elastic flexible plate. An infrared laser emitter is installed at the center of each row of air supply ducts. Multiple infrared laser receivers are installed on the blade-shaped inclined surface of the suction cylinder. These receivers are arranged continuously, and the infrared rays emitted by the multiple laser emitters have different intensities. When the continuously arranged infrared laser receivers detect infrared rays of different intensities, it is determined that the intensity of the electrorheological fluid in the central flexible bladder has changed. That is, when the intensity of the electrorheological fluid is determined to have changed, the current flowing through the central flexible bladder is increased. The formula for calculating the current adjustment is:

[0017] ;

[0018] The adjusted current value;

[0019] This is a constant, representing the initial current or reference current;

[0020] The proportionality coefficient represents the misalignment coefficient value of the infrared laser emitter;

[0021] Represents the degree of misalignment. Representing the When an infrared laser emitter is operating normally (i.e., without misalignment), the laser beam accurately illuminates the location of the target infrared laser receiver. This represents the location of the infrared laser receiver that is currently detecting the laser signal; the absolute value of the difference between the two is taken. The physical meaning obtained is: the absolute distance of the laser spot from the reference position on the receiver array. This distance value directly reflects the degree of misalignment of the air supply duct.

[0022] The formula for calculating the physical deflection angle of the air supply duct is as follows: ;

[0030] Preferably, two guide rods are fixedly connected to the mounting plate, and a fixed seat is fixedly connected to the outside of the guide rods. A sliding hole is opened on the outside of the front and rear moving plates, and the fixed seat is inserted into the sliding hole.

Furthermore, during the processing, a shield can be formed by bending an elastic flexible plate to block the flying debris. The debris can also be blown up by the air blowing, and the suction force generated by the suction hole will blow the blocked debris into the interior of the suction connecting cylinder, minimizing the phenomenon of debris falling onto the table surface.

Detailed Implementation

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1, such as Figure 1 As shown, a motor rotor machining process includes the following steps:

[0044] S1. After the initial machining of the motor rotor is completed, the motor rotor is installed on the rotating base and fixed by the rotating base. The machining drill bit is then passed through the machining hole of the machining device.

[0045] S2. After the drill bit is positioned in the processing hole of the adsorption device, fix the position of the drill bit and the motor rotor, and synchronously adjust the adsorption device and the drill bit to the processing end face of the motor rotor.

[0046] S3. Surround the central axis of the motor rotor with the external shielding of the adsorption device to shield the machined surface of the motor rotor and the central axis.

[0047] S4. After the shielding is completed, the machining drill bit is started to contact the machining end face of the motor rotor. When iron filings are generated and splashed, the adsorption device is started to simultaneously adsorb the splashed iron filings into the collection device.

[0048] This application discloses a motor rotor processing technology and processing device. The processing device in S1 includes a front and rear moving plate 102. A suction cylinder 104 is installed on the outside of the front and rear moving plate 102 by screws. A moving structure is installed on the outside of the front and rear moving plate 102. The side of the suction cylinder 104 near the rotor is a blade-shaped inclined surface. Multiple suction holes 105 are opened on the blade-shaped inclined surface of the suction cylinder 104. A suction connecting cylinder 106 is connected to one side of the suction cylinder 104. The suction connecting cylinder 106 is connected to an external suction pump.

[0049] An elastic flexible plate 107 is fixedly connected to the outside of the suction cylinder 104. A snap ring 111 is fixedly connected to the side of the suction cylinder 104 away from the elastic flexible plate 107. The side of the elastic flexible plate 107 away from the suction cylinder 104 is inserted into the inside of the snap ring 111 and surrounds the rotor to form a shield. A blowing structure is installed on the outside of the elastic flexible plate 107.

[0050] Specifically, during use, the operator can install the suction cylinder 104 onto the outside of the front and rear moving plates 102 with screws, and move the suction cylinder 104 to the drill bit position through the moving structure. The drill bit is then inserted into the suction cylinder 104 through the external opening. During processing, when the drill bit passes through the suction cylinder 104 and contacts the machining surface of the rotor, the external suction pump connected to the suction connecting cylinder 106 is activated. The external suction pump, together with the suction connecting cylinder 106 and the suction hole 105, generates a continuous suction force. During the process of the drill bit machining the rotor machining surface, the generated debris is sucked into the suction cylinder 104 by the suction force generated in the suction hole 105, and then transported to the inside of the suction connecting cylinder 106 through the suction cylinder 104, thereby completing the adsorption and collection of iron filings.

[0051] Furthermore, the suction cylinder 104 has a blade-shaped inclined surface on the side near the rotor's machined surface. This blade-shaped inclined surface reduces the volume of the suction cylinder 104 near the rotor, reducing the possibility of contact and collision between the suction cylinder 104 and the rotor shaft. The inclined surface also allows iron filings to have a landing point when they fall onto it during the suction process. After the landing point is formed, the iron filings that have fallen onto the inclined surface can be gradually drawn back into the suction cylinder 104 by the suction force. This avoids the situation where there are fewer landing points for iron filings, as is the case with traditional cylindrical suction, which would cause the iron filings to roll off the outside of the cylinder to other locations.

[0052] Furthermore, to prevent some iron filings from escaping the suction range of the suction cylinder 104 due to strong inertial force, thus failing to attract the iron filings and causing some iron filings to still fall onto the processing table, the tail end of the flexible plate 107 is inserted into the inside of the snap ring 111, thereby forming a circular shield. With the circular shield formed, even if iron filings splash outward, they will be blocked by the circular shield formed by the flexible plate 107, reducing the continuous falling of fragments onto the processing table.

[0053] like Figure 1 and Figure 5 As shown, an electrostatic sticker 501 is adhered to one side of the elastic flexible board 107, and a shielding soft cloth 500 is adhered to the side of the electrostatic sticker 501 away from the elastic flexible board 107.

[0054] Specifically, the shielding cloth 500 can be attached to one side of the airbag 108 by using the electrostatic sticker 501 to prevent flying iron filings from falling onto the worktable through the side of the elastic soft plate 107. Considering that one side of the suction cylinder 104 is the processing rotor and the other side is the drill bit moving surface, holes can be made in the outside of the shielding cloth 500 for the drill bit to pass through.

[0055] like Figure 1 As shown, the blowing structure includes an airbag 108, which is integrally formed on the outside of the elastic flexible plate 107. A gas delivery pipe 109 is connected to the outside of the airbag 108. One end of the gas delivery pipe 109 away from the airbag 108 is connected to an air pump. Multiple air supply pipes 110 are fixedly connected to the outside of the elastic flexible plate 107. The air inlet of the air supply pipe 110 is connected to the airbag 108.

[0056] Specifically, considering that during use, although debris can be blocked by the flexible plate 107, the blocked debris will still fall inside the flexible plate 107. Furthermore, when the flexible plate 107 moves away from the rotor along with the moving structure, the debris accumulated inside the flexible plate 107 may still fall onto the processing table, causing contamination. Therefore, gas is continuously injected into the airbag 108 through the gas delivery pipe 109 in conjunction with an external air pump, allowing gas to be stored inside the airbag 108. When gas enters the airbag 108... In the case of gas, the gas is delivered to the inside of the shield formed by the flexible plate 107 through multiple air supply pipes 110 connected to the airbag 108, forming a blowing effect on the debris inside the shield. When the multiple air supply pipes 110 deliver the gas into the shield, the debris inside the shield will be blown up, and the blown debris will be sucked into the suction cylinder 104 by the suction force in the suction hole 105. This reduces the accumulation of debris inside the flexible plate 107 and further prevents the debris from falling onto the processing table.

[0057] like Figures 1-7 As shown, a sliding groove is provided at the bottom of the snap ring 111, and a snap plate 600 is interference-fitted into the inside of the sliding groove.

[0058] Specifically, during use, after the flexible flexible plate 107 is inserted into the inside of the snap ring 111, the snap ring 600 can be continuously pushed upward. While pushing the snap ring 600 upward, the snap ring 600 can continuously squeeze the flexible flexible plate 107, thereby snapping and fixing the flexible flexible plate 107 located inside the snap ring 111.

[0059] Furthermore, the suction force generated by the suction pump through the suction hole 105 is greater than the gas blowing force generated by the air supply pipe 110.

[0060] like Figures 1-2 As shown, the movable structure includes a mounting plate 100, on which a front-to-back moving cylinder 101 is mounted. The output shaft end of the front-to-back moving cylinder 101 is connected to a mounting seat. The exterior of the mounting seat is fixedly connected to the exterior of the front-to-back moving plate 102 by screws. A positioning cylinder 103 is fixedly connected to the mounting seat. Two guide rods 801 are fixedly connected to the mounting plate 100. A fixing seat 800 is fixedly connected to the exterior of the guide rods 801. A sliding hole is opened on the exterior of the front-to-back moving plate 102, and the fixing seat 800 is inserted into the sliding hole.

[0061] Specifically, during use, the entire application is mounted onto the processing table via the mounting plate 100. By activating the forward and backward moving cylinder 101, the forward and backward moving plate 102 and the suction cylinder 104 can be moved forward and backward. When the suction cylinder 104 is moved to the designated position, the positioning cylinder 103 is activated. The output shaft of the positioning cylinder 103 passes through the outer wall of the forward and backward moving plate 102 and is inserted into the outer wall of the mounting plate 100, thereby positioning the overall position of the forward and backward moving plate 102. During the forward and backward movement of the forward and backward moving plate 102, the fixed seat 800 is inserted into the sliding hole, thereby guiding the forward and backward moving plate 102 via the fixed seat 800, and supporting the fixed seat 800 via the guide rod 801.

[0062] Furthermore, the reason for using a semi-flexible elastic plate 107 to form a shield is that the elastic plate 107 is lightweight and can be used with the snap ring 111 to form a shielding space of any size when rolled up. In addition, the shielding cover also needs to wrap around the rotor shaft. The position of the shaft is different in different rotor processing, and the ability to form a shielding space of any size can adapt to the different positions of the shaft, thus shielding and wrapping the rotor shaft to adapt to the processing of different rotors.

[0063] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with the prior art, in this embodiment, the volume of the suction cylinder 104 can be reduced by using the blade-shaped inclined surface, and the contact phenomenon between the suction cylinder 104 and the rotor shaft can be reduced during the processing, so that the suction cylinder 104 has a larger range of motion with the drill bit, and the drill bit can move a larger range, and the processing range of the rotor can be larger. In addition, during the processing, the flexible flexible plate 107 can be bent to form a shield to block the flying debris, and the debris can be blown up by the air blowing. Combined with the suction force generated by the suction hole 105, the blocked debris is blown into the interior of the suction connecting cylinder 106, minimizing the phenomenon of debris falling onto the table.

[0064] Example 2: Considering that during gas blowing, the blowing direction of the air supply pipe 110 changes due to the bending of the elastic flexible plate 107, and the overall blowing direction changes significantly when the elastic flexible plate 107 forms a shield, a large difference in the blowing direction may prevent the gas from accurately blowing debris into the suction cylinder 104. To address the above technical problems, this application proposes the following technical solution:

[0065] like Figures 2-3As shown, the interior of the elastic soft plate 107 has multiple central soft bladders 200 integrally formed. The interior of the central soft bladders 200 is filled with electrorheological fluid. The central soft bladders 200 surround the air supply pipe 110. An adjustment plate 201 is fixedly connected to the outside of the air supply pipe 110. The adjustment plate 201 penetrates the outer wall of the air bladder 108.

[0066] Specifically, multiple air supply ducts 110 are arranged horizontally within the flexible plate 107. Each row of air supply ducts 110 has an adjustment plate 201 on its exterior. The angle of the entire row of air supply ducts 110 can be adjusted by using the adjustment plate 201 on the currently arranged air supply ducts 110. During use, the operator can adjust the orientation angle of the entire row of air supply ducts 110 by holding the adjustment plate 201. The air supply ducts 110 are connected to the flexible plate 107 through a central soft bladder 200. The soft material of the central soft bladder 200 allows the operator to easily adjust the direction of the adjustment plate 201 and adjust the direction of the air supply ducts 110. After the direction is adjusted, the electrorheological fluid inside the central soft bladder 200 is energized by a wire. When the electrorheological fluid is energized, it will harden. The hardened electrorheological fluid can fix the air supply ducts 110, thereby limiting and fixing the blowing direction of the air supply ducts 110 as a whole.

[0067] like Figures 1-9 As shown, multiple air supply ducts 110 are arranged horizontally outside the elastic flexible plate 107. An infrared laser emitter 700 is installed at the center of each row of air supply ducts 110. Multiple infrared laser receivers 701 are installed on the blade-shaped inclined surface of the suction cylinder 104. The multiple infrared laser receivers 701 are arranged continuously. The infrared rays generated by the multiple infrared laser emitters 700 have different intensities. When the continuously arranged infrared laser receivers 701 detect infrared rays of different intensities, it is determined that the intensity of the electrorheological fluid in the central flexible bladder 200 has changed. That is, when the intensity of the electrorheological fluid is determined to have changed, the current flowing through the central flexible bladder 200 is increased. The calculation formula for the current adjustment is:

[0068] ;

[0069] The adjusted current value;

[0070] This is a constant, representing the initial current or reference current;

[0071] , is a proportionality coefficient, representing the misalignment coefficient value of the infrared laser emitter 700;

[0072] Represents the degree of misalignment. Representing the When the infrared laser emitter 700 is operating normally (i.e., without misalignment), its laser beam accurately illuminates the position of the target infrared laser receiver 701. The absolute value of the difference between the position of the infrared laser receiver 701 that actually detected the laser signal and the position of the receiver is taken. The physical meaning obtained is: the absolute distance of the laser spot from the reference position on the receiver array. This distance value directly reflects the degree of misalignment of the air supply duct 110.

[0073] Specifically, during use, the blowing direction of each row of air supply pipes 110 is controlled by the adjustment plate 201. However, the final blowing direction should be towards the suction hole 105 on the surface of the suction cylinder 104. If the orientation of the air supply pipes 110 is too off, it may cause the blowing gas to become disordered, resulting in the gas blowing debris out of the shield and causing the debris to fall onto the processing table. With the setting of the central soft capsule 200, when the adjustment plate 201 adjusts the orientation of the air supply pipes 110, it can emit a laser along with the orientation of the entire row of air supply pipes 110. By emitting the laser, the gas blowing direction of the air supply pipes 110 is visualized. After the laser emitted by the central soft capsule 200 forms a visualized gas orientation, it is convenient for the staff to adjust the gas blowing direction of the air supply pipes 110.

[0074] Furthermore, since the direction of gas blowing is ultimately towards the suction hole 105 on the surface of the suction cylinder 104, and during long-term use, it is impossible for the staff to keep an eye on the direction of each laser. Moreover, if the direction of the laser is slightly misaligned, the staff's eyes may not be able to observe it in time. However, by setting up multiple infrared laser receivers 701, the laser generated by the infrared laser emitter 700 can be received. By receiving the laser rays from multiple infrared laser emitters 700, the blowing direction of multiple air supply pipes 110 can be positioned so that the blowing direction of the air supply pipes 110 is always towards the suction cylinder 104 and the suction hole 105.

[0075] Furthermore, if signal reception between the infrared laser transmitter 700 and the infrared laser receiver 701 is lost, an external alarm will be triggered promptly. An alarm will be triggered when all multiple infrared laser transmitters 700 and infrared laser receivers 701 outside the flexible flexible board 107 are lost, while a warning will be issued for a single loss. The offset of the air supply duct 110 will be determined by the different light intensities received by the infrared laser receiver 701 from the infrared laser transmitter 700. The formula for calculating the physical deflection angle of the air supply duct 110 is as follows: ;

[0076] To represent the first The actual angular offset of the air supply duct is 110.

[0077] It is the arctangent function;

[0078] This represents the horizontal offset distance of the laser spot on the receiver array;

[0079] The fixed vertical distance represents the installation position of the infrared laser emitter 700 to the inclined surface of the suction cylinder 104 where the infrared laser receiver 701 array is located.

[0080] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, the soft material of the central soft bladder 200 allows workers to easily adjust the angle of the air supply pipe 110 using the adjustment plate 201. After adjustment, the electrorheological fluid inside the central soft bladder 200 can be energized to solidify the electrorheological fluid. The solidified electrorheological fluid can fix the air supply pipe 110, ensuring that the gas delivery direction of the air supply pipe 110 always faces the suction hole 105. Furthermore, the gas delivery direction of the air supply pipe 110 can be arbitrarily adjusted according to the different sizes of the shields formed by different infrared laser emitters 700, increasing the flexibility of rotor processing.

[0081] Example 3: Considering that during continuous gas blowing, gases with different blowing directions will be directly blown onto the elastic flexible plate 107, and the elastic flexible plate 107 is made of a deformable material, continuous gas blowing may cause the elastic flexible plate 107 to continuously shake, thereby causing the gas blowing direction to change again. To address the above technical problems, this application proposes the following technical solution to solve the above technical problems, specifically:

[0082] like Figures 3-4 As shown, the central soft capsule 200 has an integrally formed side strip-shaped fixation capsule 300 on its exterior. The side strip-shaped fixation capsule 300 is filled with electrorheological fluid, and there are no fewer than two side strip-shaped fixation capsules 300.

[0083] Specifically, during use, after the angle of the air supply duct 110 is adjusted by the electrorheological fluid inside the central soft bladder 200, the operator can energize the electrorheological fluid connected to the side strip-shaped fixing bladder 300 through wires and an external power source. When the electrorheological fluid inside the side strip-shaped fixing bladder 300 is energized, the side strip-shaped fixing bladder 300 can provide overall support for the elastic soft plate 107. There are at least two side strip-shaped fixing bladders 300, and they are arranged on the surface or both sides of the elastic soft plate 107. When there are two side strip-shaped fixing bladders 300, the two side strip-shaped fixing bladders 300 are distributed on both sides of the elastic soft plate 107. After the electrorheological fluid inside the side strip-shaped fixing bladder 300 solidifies, it can form a frame support on both sides of the elastic soft plate 107, preventing the elastic soft plate 107 from shaking when the gas is blown into it.

[0084] like Figure 4 As shown, multiple electromagnetic coils 400 are connected inside the central soft sac 200 and the side strip-shaped fixation sac 300. The electrorheological fluid inside the central soft sac 200 and the electromagnetic coils 400 are all connected to an external power source through wires.

[0085] Specifically, considering that under prolonged use, the electrorheological fluid located inside the central soft capsule 200 and the side strip-shaped fixed capsules 300 may experience sedimentation, which could weaken the curing effect of the electrorheological fluid. This weakened curing effect could cause the direction of the gas output from the air supply duct 110 to change, resulting in incorrect gas blowing direction and causing debris to fall onto the workbench. By setting up multiple electromagnetic coils 400, the electromagnetic coils 400 can be periodically energized to generate a magnetic field. This magnetic field attracts the sediment particles inside the electrorheological fluid, thus dispersing the sedimentation.

[0086] Furthermore, when misalignment occurs between the infrared laser emitter 700 and the infrared laser receiver 701, the main controller energizes the electromagnetic coil 400. This adjusts the electrorheological fluid inside the central soft bladder 200 to prevent sedimentation when the infrared laser emitter 700 and the infrared laser receiver 701 detect a change in the airflow direction of the air duct 110. This prevents misalignment caused by the failure of the air duct 110 to be fixed due to sedimentation.

[0087] The technical solutions in the above-described embodiments of this application have at least the following technical effects or advantages: Compared with Embodiment 1, in this embodiment, not only can the elastic flexible plate 107 be fixed as a whole by the side strip-shaped fixing bladders 300 on both sides in conjunction with the electrorheological fluid curing, thus preventing the airflow from the air supply duct 110 from causing the elastic flexible plate 107 to shake, but also, under long-term use or when misalignment occurs between the infrared laser emitter 700 and the infrared laser receiver 701, the change in the airflow direction of the air supply duct 110 can be detected, thereby energizing the electromagnetic coil 400. When the electromagnetic coil 400 is energized, particles inside the electrorheological fluid can be attracted, thereby reducing the precipitation phenomenon of the electrorheological fluid and avoiding the phenomenon that the precipitation of the electrorheological fluid will prevent the air supply duct 110 and the elastic flexible plate 107 from being fixed.

[0088] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
