Description

TECHNICAL FIELD Embodiments of the present invention relate to processing machines and processing systems.

Thermal power, hydraulic power, geothermal power, nuclear power generators, etc. are devices that convert rotational motion into electrical energy using the energy of steam or water. The sliding surfaces of the rotors of these generators develop uneven wear over time due to friction, heat generation, insufficient lubrication, and the like. As the uneven wear progresses, the frictional resistance with the bearing portion increases, the temperature of the sliding portion rises and vibration occurs, and the deterioration of mechanical materials and peripheral equipment progresses. For this reason, during periodic inspections of power plants, uneven wear on the sliding surfaces of rotating bodies is measured. If uneven wear exceeding the judgment value is confirmed as a result of the measurement, corrective processing will be carried out on site. It is done.

However, since the rotating bodies of thermal, hydraulic, geothermal, and nuclear power generators are large and heavy, at present, it is necessary to bring a split lathe to the site and bring in a large piece of equipment when correcting them. It needs to occupy the mouth for processing, and it needs to occupy a large space for a long time. This large equipment delivery port is a place where equipment is delivered in the power station, and if this place is occupied for a long time, it will not be possible to deliver the equipment. There is an adverse effect that it will become. In addition, the large-item loading entrance is often used for other work, etc., and cannot be occupied for a long period of time in the first place.

In order to sandwich the rotating body 2 between the two blocks 10, in the processing machine 1 according to the present embodiment, a pair of threaded rods 20 are provided in the block 10 provided in the first unit 1a and the second unit 1b. and the block 10 are penetrated in the direction in which the rotating body 2 is sandwiched. By tightening the nuts 22 provided on the top and bottom of the pair of threaded rods 20, the distance between the block 10 of the first unit 1a and the block 10 of the second unit 1b is narrowed, and the V-shaped notch 12 is formed. The first unit 1 a and the second unit 1 b can be connected to each other by sandwiching the rotating body 2 to assemble the processing machine 1 and fix it to the rotating body 2 .

It is assumed that there are various thicknesses (diameters) of the rotor 2 . Two nuts 24 are provided on the threaded rod 20 at positions inside the block 10 in order to allow the machine 1 to be mounted on rotating bodies 2 of different thicknesses. By adjusting the positions of two nuts 24 provided on each of the pair of threaded rods 20, rotating bodies 2 having various thicknesses can be configured from the first unit 1a and the second unit 1b according to the present embodiment. The processed machine 1 is ready to be installed.

FIG. 2 is a view of the processing machine 1 of FIG. 1 viewed from the right side (direction of arrow A). 1, the block 10 of the first unit 1a and the block 10 of the second unit 1b, which are provided on the left side, appear as in FIG. That is, the blocks 10 are used at two locations on both ends in the length direction of the rotating body 2 in the processing machine 1 of FIG. The processing machine 1 is fixed to the rotating body 2 by sandwiching the rotating body 2 between the V-shaped notches 12 of the block 10 .

The processing machine 1 further includes fixing portions 30 to which the blocks 10 are attached at both ends of the rotating body 2 in the longitudinal direction.

That is, eight guides 44 are provided between the pair of both end support portions 42 so that when attached to the rotating body 2, they are circumferentially arranged substantially evenly around the rotating body 2. ing. That is, in this embodiment, the guides 44 are arranged at intervals of 45°. By arranging the guides 44 circumferentially in this manner, it is possible to suppress the moment load of the rotating mechanism section 40 . In addition, since the eight guides are arranged so as to be positioned on opposite sides of each other by 180°, it is possible to realize highly accurate cutting without eccentricity of the rotating mechanism section 40 . Furthermore, by setting the number of the guides 44 to eight, it becomes possible to improve the precision of the cutting work compared to providing four or six guides 44 . However, depending on the rigidity of the guides 44, the fixed part 30, and the rotating body 2, the number of the guides 44 can be changed to another number such as four, six, or ten.

A support portion 46 and a rotary gear 48 are provided adjacent to one end portion between the two end support portions 42 . Both the supporting portion 46 and the rotating gear 48 are donut-shaped like the both-end supporting portion 42, and the rotating body 2 is positioned in the central portion where the space is formed.

However, the transverse portion 54 is movable along the guide 44 between the rotary gear 48 and the support portion 52 . That is, the traversing portion 54 is rotatable around the rotating body 2 together with the guide 44, but is not fixed to the guide 44 and is slidably mounted on the guide 44 along the length direction of the rotating body 2. It is

A cutting mechanism 56 is provided at one location on the outer periphery of the transverse portion 54 .

That is, the end supports 42, the guides 44, the supports 46, 50, 52, the rotating gear 48, the traversing portion 54, and the cutting mechanism 56 are immovable relative to each other. Therefore, the both-end support portions 42, the guides 44, the support portions 46, 50, 52, the rotating gear 48, the traversing portion 54, and the cutting mechanism 56 are integrated, and the rotation axis of the rotating body 2 is the center. rotate as The cutting mechanism 56 cuts the rotating body 2 while the rotating mechanism 40 rotates around the rotating body 2 , thereby correcting the cutting of the rotating body 2 . Specifically, the cutting tool 60 of the cutting mechanism 56 cuts the outer circumference of the rotating body 2 to realize the correction processing of the rotating body 2 .

FIG. 5 is a view partially showing a BB line cross section of the processing machine 1 in FIG. That is, FIG. 5 is a sectional view showing 1/4 of the entire processing machine 1 in FIG. As shown in FIG. 5, a cylindrical guide 70 is provided on the outer peripheral portion of the rotary gear 48 . The cylindrical guide 70 rotatably holds the rotary gear 48 via bearings or the like. Also, the cylindrical guide 70 is fixedly attached to the fixed portion 30 via the support portion 72 . As a result, the cylindrical guide 70 is attached relatively immovably to the rotating body 2 .

A cylindrical guide 74 is also provided on the opposite side of the cylindrical guide 70 in the processing machine 1 . This cylindrical guide 74 rotatably holds the support portion 52 . That is, the cylindrical guide 74 is immovably attached to the fixed portion 30 via the support portion 76 . As a result, the cylindrical guide 74 is attached relatively immovably to the rotating body 2 .

As shown in FIGS. 1 and 2 again, the processing machine 1 has a motor 80 . In this embodiment, the motor 80 is fixedly mounted above the fixed portion 30 and the support portion 72 . A gear mechanism 82 is provided on the tip shaft of the motor 80 , and the rotational driving force of the motor 80 is transmitted to the rotary gear 48 via the gear mechanism 82 . In this embodiment, for example, two combination gears 84 and 86 constitute a gear mechanism 82 . The gear 84 is connected to the rotating shaft of the motor 80, and when the motor 80 is driven to rotate, the gear 84 rotates, the rotation is transmitted to the gear 86, and the rotation is further transmitted to the rotating gear 48. .

The processing machine 1 also includes a feed mechanism 100 for moving the traversing section 54 along the length direction of the rotating body 2 . In this embodiment, the feed mechanism 100 is configured with a feed screw 102 , a pad 104 and a motor 106 . The lead screw 102 is rotatably attached to the supports 72, 76 along its central axis by fasteners 108, 110 at both ends thereof. One end of the feed screw 102 is connected to a motor 106 attached to the fixed part 30 . When the motor 106 is rotationally driven, the feed screw 102 is also rotated. moves left and right along the length direction of the rotor 2 . For example, the forward rotation of the motor 106 moves the pad 104 to the right, and the reverse rotation of the motor 106 moves the pad 104 to the left.

FIG. 6 is a cross-sectional view of the pad 104 including the feed screw 102 according to this embodiment. As shown in FIG. 6, the pad 104 according to the present embodiment is formed with a through hole 106 through which the feed screw 102 passes, and the through hole 106 is spirally grooved. . A screw thread formed in a spiral shape on the feed screw 102 is engaged with a thread groove formed in a spiral shape in the through hole 106, and the pad 104 moves as the feed screw 102 rotates. there is

Further, the pad 104 is formed with a sandwiching portion 108 that sandwiches the transverse portion 54 , and has a structure in which the lateral portion 54 is sandwiched between the sandwiching portions 108 . Therefore, when the pad 104 moves, the transverse portion 54 also moves accordingly. That is, there is sliding between the concave portion of the clamping portion 108 and the transverse portion 54 , and even if the transverse portion 54 rotates with the rotation of the rotating mechanism portion 40 , the rotational force is not transmitted to the pad 104 .

Therefore, by moving the pad 104 with the motor 106 while rotating the rotation mechanism section 40 with the motor 80, the cutting mechanism 56 provided in the traversing section 54 can machine the outer diameter of the rotating body 2. . The amount of cutting to be applied is adjusted by the feed amount of the cutting tool 60 by the tool holding mechanism 62 in the cutting mechanism 56 .

Moreover, as can be seen from FIG. 2, in this embodiment, the feed mechanism 100 is provided on both the left and right sides of the processing machine 1 . Therefore, the rotational drive of the motor 106 is synchronously controlled, and the feed amount of the feed screw 102 is controlled to be equal between the left and right sides. It should be noted that it is not always necessary to provide two feed mechanisms 100 , and only one may be provided for the entire processing machine 1 . Furthermore, the processing machine 1 may be provided with three, four, or the like feeding mechanisms 100 .

Again, as shown in FIGS. 1 and 2 , the processing machine 1 according to this embodiment includes a press screw portion 110 in the fixed portion 30 . In this embodiment, four push screw portions 110 are provided for one fixed portion 30 , and each push screw portion 110 is connected to the support portion 76 . Therefore, by finely adjusting the position of the set screw portion 110, the centers of the processing machine 1 and the rotating body 2 can be aligned.

As described above, according to the processing machine 1 according to the present embodiment, the processing machine 1 is configured by being divided into a plurality of units. It is possible to facilitate the carrying-in work. By assembling and connecting the plurality of units around the rotating body 2 , the processing machine 1 can be fixedly attached to the rotating body 2 . Then, the outer diameter of the rotating body 2 can be machined using the cutting mechanism 56 by the processing machine 1 fixed to the rotating body 2 .

More specifically, by rotating the motor 80, the rotating gear 48 rotates, thereby rotating the rotating mechanism 40 around the rotating body 2 while the processing machine 1 itself is fixed to the rotating body 2. can be made As the rotation mechanism 40 rotates, the traversing section 54 also rotates, and the cutting mechanism 56 attached to this traversing section 54 also rotates. Further, the motor 106 is also rotationally driven, the feed screw 102 rotates, and the transverse portion 54 moves along the length direction of the rotating body 2 . Therefore, for example, the cutting mechanism 56 can be moved from one end of the rotating body 2 to the other end while rotating around the rotating body 2 . During this movement, by adjusting the feed amount of the cutting tool 60 of the cutting mechanism 56, the rotary body 2 can be cut.

Furthermore, since the processing machine 1 is fixed to the rotating body 2, even if the rotating body 2 is installed obliquely or vertically, the processing machine 1 can be attached to the rotating body 2 and rotated. Cutting of the body 2 can be performed. Therefore, the availability of the processing machine 1 can be greatly expanded.

Therefore, the cutting mechanism 56 can be moved along the length direction of the rotating body 2 by rotationally driving the motor 106 . In addition, the transverse section 154 is configured to be rotatable around the rotating body 2 by a chain mechanism 156 that is also connected to the outside. That is, the outer peripheral portion of the transverse portion 154 is attached to the eight guides 44 so as to be movable in the longitudinal direction of the rotating body 2, and the inner peripheral portion of the transverse portion 154 rotates inwardly of the outer peripheral portion. It is mounted rotatably around the body 2 . A cutting mechanism 56 is provided on the inner periphery of the transverse portion 154 , and when the driving force of the chain mechanism 156 rotates the inner periphery around the rotating body 2 , the cutting mechanism 56 also rotates. Thereby, the outer circumference of the rotor 2 can be machined by the cutting mechanism 56 .

As described above, the processing machine 1 composed of a plurality of units can be assembled around the rotating body 2 also in this modified example. In this modification, the inner peripheral portion of the traversing portion 154 rotates, and the cutting mechanism 56 attached to this inner peripheral portion also rotates around the rotating body 2, so that the surface of the rotating body 2 can be cut. can. Then, the feed mechanism 100 moves the cutting mechanism 56 from one side of the rotating body 2 to the other while rotating the inner peripheral portion of the transverse portion 154, thereby cutting the outer periphery of the rotating body 2 along the length direction. be able to.

(Second embodiment)

The tool holding mechanism 62 can adjust the amount of radial movement of the cutting tool 60 , and the adjustment is performed radially outward of the rotating body 2 .

A bearing support portion 200 is positioned radially outward of the rotating body 2 . That is, FIG. 9 shows a state in which the bearing between the rotating body 2 and the bearing support portion 200 is disassembled and taken out, and the processing machine 1 is inserted into the gap. This bearing support portion 200 is provided around the entire circumference of the rotating body 2 .

Further, the movement amounts of the motors 80 and 106 are also transmitted to the data collection device 410 as pulse signals. Information about the amount of movement may be transmitted directly from the motors 80 and 106 to the data collection device 410 or may be transmitted to the data collection device 410 via the data transmission section 404 . Also, the communication method may be wireless or wired.

In this embodiment, data regarding the amount of displacement of the displacement gauge 400 and data regarding the amount of movement of the motors 80 and 106 are received by the programmable logic controller 412 of the data acquisition device 410 . That is, the programmable logic controller 412 receives the displacement amount of the displacement meter 400 and the movement amounts of the motors 80 and 106 in a synchronized state, and transfers them to the computer 420 .

The computer 420 is, for example, a so-called personal computer, and includes an analysis unit 422 that analyzes the displacement amount of the displacement meter 400 and the movement amount of the motor 80 and the motor 106 received from the programmable logic controller 412, and the analysis unit 422. and a display unit 424 for displaying the result analyzed by the unit 422 . The analysis unit 422 is configured by, for example, software for analyzing the displacement amount of the displacement gauge 400 and the movement amount of the motors 80 and 106. The display unit 424 is, for example, a liquid crystal display or a CRT (Cathode Ray Tube) display. etc.

In view of the above configuration, in the present embodiment, the processing system 4 for cutting the rotating body 2 is configured by the processing machine 1 having the displacement gauge 400, the data collection device 410, and the computer 420. It is considered to be The processing system 4 as described above can realize the following.

For example, while the rotation of the rotating mechanism 40 is stopped, the transverse portion 54 is moved from one longitudinal end of the rotating body 2 to the other longitudinal end of the rotating body 2 so as to rotate the surface of the rotating body 2 in the longitudinal direction. It is possible to measure the displacement of the state of

FIG. 13 shows an example of measurement results of displacement of the surface of the rotating body 2 at the 0° position and the 180° position of the rotating body 2, for example. FIG. 13 shows the results of measuring the surface of the rotor 2 in order to confirm the state of uneven wear before correcting the rotor 2 . As shown in FIG. 13, sound surfaces 430 that are not in contact with the bearings are provided at both ends of the rotating body 2 in the longitudinal direction. Since this sound surface 430 does not contact the bearing, uneven wear does not occur, and the surface of the rotating body 2 maintains a smooth perfect circle.

On the other hand, the portion of the rotating body 2 that contacts the bearing has uneven wear on its surface due to the wear of the bearing with the bearing or the like. Therefore, when the surface of the rotating body 2 is measured by the displacement meter 400, it can be observed that the surface has unevenness. The amount of processing by the processing machine 1 is adjusted according to the amount of this uneven wear. That is, it is possible to obtain the amount of corrective machining necessary to return the sliding surface of the rotating body 2 to a perfectly circular state. In general, the amount of corrective machining is determined by taking into consideration the amount of uneven wear and a slight allowance for finishing machining. For example, if the amount of uneven wear is 35 μm, the margin amount is set to 10 μm, and the correction machining amount is set to 45 μm.

When the maximum processing amount set in the processing machine 1 is 30 μm, the computer 420 sets the first correction processing amount to 30 μm and the second correction processing amount to 15 μm. Designed.

In addition, since the rotating body 2 slides so as to rotate constantly for many years, it is known that the circumference of the rotating body 2 decreases by approximately the same amount. Therefore, the wear state of the rotating body 2 can be grasped only by measuring the length direction of the rotating body 2 with the displacement meter 400 at only one angle. In this case, for example, the surface of the rotating body 2 may be measured only at the 0° position.

Furthermore, by measuring the surface of the rotating body 2 at, for example, a pitch of 90°, it is possible to confirm the attachment state of the processing machine 1 to the rotating body 2 . That is, when the horizontal and vertical surface displacement amounts are constant, it means that the processing machine 1 can be mounted straight with respect to the rotation axis center of the rotor 2 . The roundness of the rotating body 2 can also be grasped by this method. It should be noted that the angle of the pitch of the rotating body 2 to be measured is arbitrary. For example, if the surface of the rotating body 2 is measured at a pitch of 45°, the surface can be measured at eight locations on the rotating body 2 .

Alternatively, with the traversing section 54 of the processing machine 1 stopped at one position, the rotating mechanism section 40 is rotated, and the displacement meter 400 measures the surface of the rotating body 2 along the circumferential direction of the rotating body 2. Thus, the roundness of the rotating body 2 can be measured with high accuracy. This roundness measurement can be performed before cutting the rotating body 2 to determine the amount of machining, or after cutting the rotating body 2 to check the machining accuracy. can.

Next, the processing machine 1 having a function of adjusting the depth of cut during processing will be described with reference to FIGS. 14 and 15. FIG. FIG. 14 is a view showing the processing machine 1 in which the cutting mechanism 56 is provided with a depth-of-cut adjustment function, and FIG. 15 is a view of the cutting mechanism 56 as seen from the direction of arrow D in FIG.

As shown in FIGS. 14 and 15 , the cutting mechanism 56 makes the cutting tool 60 radially movable using the driving force of the motor 430 . In controlling the motor 430, the control unit 432 receives a control signal wirelessly or by wire, and controls the motor 430 based on the received control signal. The motor 430 has, for example, a battery 434 and operates with electric power provided by the battery 434 .

A motor 430 rotates a threaded rod 436 provided in the cutting mechanism 56 . Threaded rod 436 is rotatably retained via a T-slot nut and coupled to cutting tool 60 . Therefore, rotation of the threaded rod 436 causes radial movement of the cutting tool 60 . For example, when the motor 430 rotates forward, the cutting tool 60 moves in the direction in which the cutting tool 60 protrudes, thereby increasing the depth of cut. On the other hand, by rotating the motor 430 in the reverse direction, the cutting tool 60 moves in the retracting direction, and the depth of cut can be reduced. Control of this motor 430 can be performed by a user from computer 420, for example.

As described above, according to the processing machine 1 according to the present embodiment and the processing system 4 including such a processing machine 1, the surface of the rotating body 2 is measured using the displacement meter 400 before processing the rotating body 2. By measuring , the uneven wear amount of the rotor 2 can be measured in advance. Therefore, the amount of processing by the processing machine 1 can be calculated more accurately.

Also, if the amount to be processed of the rotating body 2 exceeds the maximum processing amount of the processing machine 1, how to divide the processing amount and process the rotating body 2 multiple times? The computer 420 can pre-compute what should be done. Therefore, the processing efficiency of the rotating body 2 by the processing machine 1 can be improved.

Furthermore, even after cutting the rotating body 2 by the processing machine 1, the state of the rotating body 2 after machining can be easily confirmed. For example, along the length direction of the rotating body 2, by measuring the state of its surface, or along the circumferential direction of the rotating body 2, by measuring the roundness, appropriate cutting has been performed on the rotating body 2.

It should be noted that the fourth embodiment has been described so far by taking as an example the case where the displacement gauge 400 according to the present embodiment is applied to the first embodiment, but the displacement gauge 400 can be similarly applied to other embodiments. Needless to say.
