Description

Technical Field

[0001] The invention relates to the technical field of high-voltage motor main shaft repair, and in particular to a disassembly-free repair device for a high-voltage motor electric slip ring. Background Art

[0002] In the field of engineering machinery, power plants or chemical industry, large high-voltage motors are often needed as power sources. Among them, the brush is a device that transmits energy or signals between the fixed part and the rotating part of the motor, generator or other rotating machinery. It is generally made of pure carbon and a coagulant, and its appearance is generally a square; it is stuck on the metal bracket, and there is a spring inside to press it tightly on the main shaft. For this reason, during the long-term operation of the high-voltage motor, the area where the electric slip ring is installed on the main shaft is very easy to wear. Since the electric slip ring groove on the motor main shaft has been worn, the coaxiality is difficult to ensure. If the worn main shaft continues to be used, the wear of the electric slip ring will increase, which will directly affect the normal operation of the high-voltage motor; at this time, even if a new electric slip ring is replaced, the electric slip ring groove on the entire motor is still severely worn, so the electric slip ring groove will still accelerate the wear of the electric slip ring. For this reason, the severely worn main shaft needs to be removed from the high-voltage motor and then repaired or replaced. With the popularization of additive manufacturing technology and 3D printing technology, the main shaft of the high-voltage motor is generally reprocessed using additive repair technology and 3D printing technology after conventional wear. The repair process is: laser cladding technology is used to perform point-by-point accumulation on the worn area of ​​the main shaft of the high-voltage motor, so that the worn area of ​​the main shaft can gradually fill the worn part, and the material properties of the repaired area are the same as those of other areas of the main shaft. Therefore, the performance of the repaired main shaft can basically meet the work requirements.

[0003] Additive manufacturing technology can achieve disassembly-free processing through manual welding, but the spindle after additive manufacturing still needs to grind and turn the excess parts. If manual disassembly-free grinding is used, it is difficult to ensure the coaxiality of the spindle in the electric slip ring area. Therefore, in the actual maintenance process, the entire spindle still needs to be removed from the high-voltage motor and then placed on a large turning equipment for turning. The excess parts on the spindle are cut off to ensure the coaxiality of the electric slip ring on the spindle. Because the high-voltage motor is huge in size, the weight of the spindle alone can reach more than ten tons to dozens of tons. Therefore, it is very troublesome to disassemble and assemble the spindle of the high-voltage motor. At the same time, the components installed on the spindle or the components that cooperate with the spindle are generally customized products. Therefore, it is difficult to disassemble and assemble the spindle, and it is easy to damage other components. Moreover, the installation position of the spindle needs to be adjusted again to ensure the accuracy of the spindle installation when the spindle is reinstalled later. The whole debugging process is very troublesome. Summary of the invention

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0026] See also Figures 1 to 5The present application provides a high-voltage motor slip ring non-disassembly repair device, which is installed on the high-voltage motor housing, and includes a mounting base 10, a plurality of clamping bodies 20, a main seat 30, a sliding seat 40 and an adjusting member 60; a mounting position 15 is provided on the back of the mounting base 10; the adjusting member 60 is slidably mounted on the back of the mounting base 10 and is internally locked on the mounting position 15, and a plurality of stepped surfaces 61 of different heights are provided on the outward side of the adjusting member 60; each of the clamping bodies 20 is provided with a plurality of mounting base surfaces 21, and each of the clamping bodies 20 is provided with a plurality of mounting base surfaces 21 through any of the The mounting base 21 is installed on the stepped surface 61 in an adjustable manner; the distance between any mounting base 21 on each of the clamping bodies 20 and the clamping end of the clamping body 20 is not equal; the main body seat 30 is installed on the mounting base 10 in an adjustable manner, the main body seat 30 can be locked relative to the mounting base 10, and an adjustment mechanism is provided on the main body seat 30; the sliding seat 40 is slidably installed on the main body seat 30, the sliding seat 40 is installed on the adjustment end of the adjustment mechanism, and the tool 41 is detachably installed on the sliding seat 40. Among them, the sliding seat 40 is similar to a tool holder structure with adjustable position, which is used to fix the tool 41 and cooperate with the adjustment mechanism to provide a cutting feed amount, so as to facilitate the control of the cutting feed amount. Among them, the distance between each mounting base 21 and the clamping end of the clamping body 20 is not equal. In addition to realizing the leveling of the mounting base 10, such a design can also realize the feed depth by adopting mounting bases 21 of different heights, thereby improving the adaptability of processing.

[0027] It should be noted that in the present application, the design that the main seat 30 can be rotatably or positionally adjusted to be installed on the mounting base 10 can, to a certain extent, realize machining and cutting in different states according to different mounting positions, by adjusting the relative spatial position of the main seat 30 and the mounting base 10. In addition, in the present application, the rotation of the high-voltage motor itself is used to provide a cutting power, and the mounting base 10 in the present application is installed on the housing of the high-voltage motor, so that the relative rotation of the two can be realized, and then the cutting function can be realized, and at the same time, the coaxiality between the cutting part of the spindle and the spindle body can be ensured.

[0028] See again Figures 1 to 3As described above, the present repair processing device needs to adjust the feed depth or installation position through the clamping body 20. To facilitate fixing the clamping body 20 on the end face of the housing of the high-voltage motor, in one embodiment of the present application, the clamping body 20 is provided with a clamping hole 22, wherein the housing of the high-voltage motor generally has a mounting hole or a positioning pin shaft and other structures. The clamping hole 22 of the present application is used to be mounted on the mounting structure of the high-voltage motor housing, and there are at least two mounting base surfaces 21 whose distances are not equal to the center of the clamping hole 22. In order to better fix the position of the clamping body 20 relative to the mounting structure of the high-voltage motor housing, the clamping body 20 is provided with an opening 25, and the opening 25 is connected to the clamping hole 22. The clamping body 20 is provided with connecting ears 23 on both sides of the outward end of the opening 25, and the two connecting ears 23 are connected by an adjusting bolt 24, and the adjusting bolt 24 can adjust the distance between the two connecting ears 23. Therefore, through the above design, the entire clamping body 20 and the mounting structure of the high-voltage motor housing are relatively easy to disassemble and fix, thereby improving the work efficiency. The distances between the above-mentioned different mounting base surfaces 21 and the center of the clamping hole 22 are not equal. Such a design can facilitate the staff to level the mounting base 10 according to the actual installation situation, thereby ensuring the processing accuracy of the entire repair processing device.

[0029] In order to install the adjustment member 60 and adjust the distance between the mounting base 10 and the center of the clamping hole 22 according to the adjustment member 60, in one embodiment of the present application, a slide groove 14 is provided on the back of the mounting base 10, the slide groove 14 passes through the mounting position 15, the adjustment member 60 is slidably installed in the slide groove 14, the adjustment member 60 is provided with a slide groove 63 along its length direction, the mounting position 15 is provided with a through hole 16, a fastening bolt 17 is penetrated in the through hole 16, the threaded end of the fastening bolt 17 movably passes through the slide groove 63 and is connected to the threaded hole 26 on the mounting base surface 21; an inclined surface 62 is provided between two adjacent stepped surfaces 61. Among them, the mounting position 15 is a raised structure, which is convenient for connection with the mounting base surface 21. When it is necessary to adjust the distance of the entire mounting base 10 relative to the center of the clamping hole 22, the staff only needs to slide the adjustment member 60 in the slide slot 14. In this way, the step surface 61 of different heights can be used to increase the distance of the adjustment member 60 from the bottom of the slide slot 14 to the outside. Such a design uses the change of the distance of the entire mounting base 10 relative to the center of the clamping hole 22 to adapt to the needs of different installation positions. Among them, the fastening bolt 17 can cooperate with the clamping body 20 to form a bolt and nut structure. Such a design can lock and fix the clamping body 20 on the step surface 61. In some embodiments, due to the uneven installation position of the clamping body 20 itself, the staff can directly contact the mounting base surface 21 with the inclined surface 62. Such a design can level the entire mounting base 10 to a certain extent.

[0030] In the improved scheme of the above embodiment, in order to facilitate the disassembly and adjustment between the mounting base 21 and the mounting base 10, the mounting base 21 is installed on the mounting base 10 by fixing bolts, and the fixing bolts are provided with adjusting gaskets. The adjusting gasket 2 is installed on the gap between the mounting base 21 and the back of the mounting base 10 in an adjustable manner. One side of the adjusting gasket has an inclined slope, and one end of the adjusting gasket located at the top of the inclined slope extends out of the gap. The size of the gap is adjusted by using the inclined slope on the adjusting gasket, while also ensuring the tight connection between the mounting base 21 and the mounting base 10 to prevent the two from loosening. In addition, the adjusting gasket can also extend the distance between the mounting base 21 and the center of the clamping hole 22, thereby increasing the overall adjustment stroke. It should be particularly noted that in the present application, the inclined slope is a stepped slope structure, and such a design facilitates each step on the inclined slope to fit with the mounting base 21 or the mounting base 10, thereby increasing the contact area between the two and ensuring the stability of the connection.

[0031] Furthermore, in order to facilitate the later storage and transportation, in addition to the design of disassembly of the mounting base 10 and the main body 30, in one embodiment of the present application, a rotating shaft 11 is provided on the mounting base 10, and the back of the main body 30 is rotatably mounted on the rotating shaft 11, and a plurality of fixing holes 12 are provided on the mounting base 10, and the main body 30 is locked on the mounting base 10 by means of locking bolts 13 cooperating with the fixing holes 12. Among them, when not working, the mounting base 10 can rotate and overlap relative to the main body 30, which can save the trouble of overall disassembly, and only the locking bolts 13 need to be loosened. Of course, in some embodiments, the design that the mounting base 10 can rotate relative to the main body 30 can also adjust the spatial orientation of the main body 30, and then adjust the orientation of the transmission screw 31 and the tool 41, so as to adapt to different processing conditions.

[0032] See also Figures 1 to 4 In order to achieve accurate control of the feed amount, in one embodiment of the present application, the adjustment mechanism includes a transmission screw 31, an anti-slip mechanism 50 is provided on one end of the main body seat 30, one end of the transmission screw 31 is rotatably connected to the anti-slip mechanism 50, and the other end of the transmission screw 31 can be rotatably mounted on the main body seat 30. In actual operation, the transmission screw 31 is manually controlled or other devices are used to control the feed amount, so it is simpler and more convenient to realize feeding through the transmission screw 31, and the feeding accuracy is high. In addition, in the actual processing process, when the tool 41 cuts the cutting part on the cutting spindle, the reaction force of the cutting part on the spindle on the tool 41 will eventually be applied to the main seat 30 through the transmission screw 31. The entire spindle has a large diameter and a long processing stroke, which easily leads to increased wear between the transmission screw 31 and the main seat 30, and the feed accuracy is easily reduced in the later stage. For this reason, the present application designs an anti-slip mechanism 50 to offset the axial force of the transmission screw 31 and reduce the wear between the transmission screw 31 and the main seat 30.

[0033] In the above embodiment, the anti-movement mechanism 50 can be a thrust ball bearing structure, or some other force-relieving structures, such as a limit ring or a buffer structure. In fact, the anti-movement mechanism 50 can be installed on one end of the transmission screw 31, or can be mounted on the transmission screw 31, as long as it can meet the above requirements.

[0034] See also Figure 3 to Figure 4In one embodiment of the present application, in order to better achieve the force release of the transmission screw 31 and prevent the transmission screw 31 from axial movement, the anti-movement mechanism 50 includes a main body block 51 and a cover block 52, one side of the main body block 51 is installed on one end of the main seat 30, and the cover block 52 can be detachably installed on the other side of the main body block 51, and the main body block 51 and the cover block 52 are both provided with mounting holes 53, one end of the transmission screw 31 can be rotatably installed in the mounting holes 53 on the main body block 51 and the cover block 52, and a step section 54 is provided on the end of the mounting hole 53 on the main body block 51 close to the cover block 52, and the diameter of the step section 54 is larger than the diameter of the mounting hole 53, and a rotating member 32 is provided on the transmission screw 31, and the rotating member 32 can only rotate relative to the transmission screw 31 or the two rotate synchronously, and the rotating member 32 can be rotatably installed in the step section 54, and the length of the step section 54 is adapted to the length of the rotating member 32. Among them, in this embodiment, the anti-movement mechanism 50 plays the role of supporting and limiting the transmission screw 31, and uses the space formed by the step section 54 to limit the movement of the rotating member 32 in the axial direction thereof. In addition, the above-mentioned main body block 51 and cover block 52 are both fixed to one end of the main body seat 30 by bolts, which can save the trouble of separate installation. In fact, in order to reduce friction, a bearing can be installed between the transmission screw 31 and the mounting hole 53, which is selected according to actual needs.

[0035] In the above embodiment, the rotating member 32 cannot move in the axial direction relative to the transmission screw 31, otherwise the function of preventing movement and the function of force release cannot be achieved. The rotating member 32 can be designed as an integral part with the transmission screw 31, or it can be a split design; if it is an integral design, the rotating member 32 can be regarded as a convex ring structure on the transmission screw 31; if it is a split design, the ring structure can be mounted on the transmission screw 31 according to the needs.

[0036] See also Figure 3 and Figure 4Therefore, in an improved embodiment of the present application, the rotating member 32 includes a pair of semi-ring bearings 33, the two semi-ring bearings 33 can be buckled together to form a ring and are mounted on the outer wall of the transmission screw 31, the inner walls of the two semi-ring bearings 33 are in contact with the outer wall of the transmission screw 31, and the inner walls of the two semi-ring bearings 33 are provided with limiting grooves 34, and the transmission screw 31 is provided with a limiting convex ring 35 for matching the limiting grooves 34. Among them, after the two semi-ring bearings 33 are buckled, the limiting grooves 34 form a ring groove structure. In the present application, the rotating member 32 is designed as a split body, which is convenient for later disassembly and maintenance; at the same time, the rotating member 32 is designed as a bearing structure, so that the rotating member 32 can not only realize the limiting anti-slipping effect required in the present application, but also can play the role of supporting the transmission screw 31, so that the friction between the transmission screw 31 and the mounting hole 53 during the rotation process can be reduced, so that the transmission screw 31 can be rotated more easily. In addition, in order to improve lubricity, an oil storage space 36 is formed between the limiting groove 34 and the outer peripheral side wall of the limiting convex ring 35, that is, in actual use, the outer diameter of the limiting convex ring 35 is smaller than the diameter of the bottom of the limiting groove 34, so that they can cooperate with each other to form an oil storage space 36, so that the lubricating oil in the oil storage space 36 can automatically lubricate the entire rotating part 32 and the rotating part 32 and the step section 54 during the rotation process.

[0037] See also Figure 5, since the transmission screw 31 is always subjected to an axial force during the cutting process of the tool 41, the transmission screw 31 will drive the end face of the rotating member 32 to abut against the end face of the step section 54 or the cover block 52, and the two abut against each other to release force. In this case, both ends of the rotating member 32 are prone to wear, and long-term use will cause the length of the rotating member 32 to decrease, thereby reducing the anti-movement ability. To address such a situation, in an improved embodiment of the present application, both ends of the rotating member 32 are provided with an annular groove 37 recessed inwardly, and an abutment ring 38 is rotatably installed in the annular groove 37, and the inner and outer rings of the abutment ring 38 are respectively abutted against the inner and outer rings of the annular groove 37 through a sealing ring, and a step 39 is provided on the outer ring of the abutment ring 38 on the outward side, and a limiting ring 3a is movably mounted on the step 39, and the outer ring of the limiting ring 3a is connected to the end face of the rotating member 32, and the thickness of the limiting ring 3a is less than the thickness of the step 39; an oil storage chamber 3b is formed between the abutment ring 38 and the bottom of the annular groove 37, and an oil injection hole 3c connected to the oil storage chamber 3b is provided on the abutment ring 38, and the oil injection hole 3c can be opened and closed, and the oil storage chamber 3b is filled with lubricating oil, and the lubricating oil in the oil storage chamber 3b can force the step 39 to always abut against the limiting ring 3a. Among them, in actual use, the outward side of the abutment ring 38 abuts against the end face of the step section 54 or the cover block 52. At this time, since the transmission screw 31 has a certain axial force and will compress the abutment ring 38, the abutment ring 38 is forced to slide to the bottom of the annular groove 37. At this time, the lubricating oil in the oil storage chamber 3b is compressed, and the abutment ring 38 can make the abutment between the step 39 and the limiting ring 3a drop or not contact; and the entire abutment ring 38 is equivalent to being suspended in the annular groove 37. At this time, there is basically no friction between the abutment ring 38 and the entire rotating part 32, which greatly reduces the friction between the two and avoids wear between the two. At the same time, in the actual processing process, since the repaired part of the spindle is obtained by additive manufacturing, it is difficult to ensure that the texture of the repaired area is uneven. The repaired part of the turning spindle may encounter a local hard part. At this time, the tool 41 will jump with the local hard part during the cutting process at a predetermined cutting depth, that is, the tool 41 automatically skips the local hard part and reduces the cutting depth to adapt to the local hard part being cut. The jumping process of the tool 41 will drive the entire sliding seat 40 and the transmission screw 31 to vibrate. For this reason, the oil storage chamber 3b in this application can absorb and buffer the vibration force and impact force transmitted by the tool 41 to the transmission screw 31 to a certain extent, so that the entire repair processing device moves more smoothly. Among them, an oil plug structure is provided on the oil filling hole 3c, so that the pressure in the oil storage chamber 3b can be guaranteed.
