Description

Technical Field

[0001] This utility model relates to the field of magnetic pole repair technology for ultra-precision machinery, and in particular to a device for repairing the runout of the magnetic pole end face of ultra-precision machinery. Background Technology

[0002] In the field of ultra-precision equipment for raceways in the bearing processing industry, after the magnetic poles are installed on the machine, frequent operation can lead to wear, scratches, or excessive runout of the magnetic pole end face due to inherent reasons. When this significantly affects the ultra-precision accuracy of the raceway, it is necessary to re-grind the magnetic pole end face. Current technology typically involves removing the magnetic poles, smoothing them with a surface grinder, and then reinstalling and adjusting them. This process is time-consuming and labor-intensive. However, this is only possible if the workpiece spindle end face of the ultra-precision machine is free from wear. If the ultra-precision machine has been used for two or three years, the workpiece spindle end face will also wear down. Even if the magnetic poles are installed with zero parallelism, the required precision cannot be achieved. This is a major drawback of this type of ultra-precision machine.

[0003] Therefore, this application proposes a novel magnetic pole end face repair device that can repair the magnetic pole end face without disassembling the magnetic pole, ensuring the optimal precision of the magnetic pole end face. Utility Model Content

[0004] The purpose of this invention is to solve the problems in the prior art by proposing a device for repairing the runout of the magnetic extreme surface of ultra-precision machinery.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A device for repairing magnetic end face runout of an ultra-precision machine includes a repair component for repairing the magnetic end face and a mounting base for mounting the repair component. The mounting base includes a fixed base fixed on the ultra-precision machine and a sliding component and a feeding component for moving the repair component. The repair component is fixed above the sliding component by a mounting ring. A viewing plate is provided on the upper surface of the mounting ring, and the viewing plate is mounted above the mounting ring by the mounting component.

[0006] In some embodiments, the repair assembly includes a motor and a grinding wheel fixed to the output end of the motor, the grinding wheel being a diamond grinding wheel.

[0007] In some embodiments, the sliding assembly includes two guide rails fixed to the upper surface of the horizontal plate and a slide block that slides on the surfaces of the two guide rails, the slide block sliding on the surfaces of the two guide rails via a feeding assembly.

[0008] In some embodiments, the mounting ring includes a lower ring body fixed to the upper surface of the slide and an upper ring body fixed above the lower ring body, and the motor is clamped and fixed by the upper ring body and the lower ring body.

[0009] In some embodiments, the mounting assembly includes a connecting plate fixed to the bottom of the viewing plate and two fixing plates fixed to the upper surface of the upper ring body. The connecting plate rotates on the surfaces of the two fixing plates via two rotating shafts, which are respectively located at both ends of the connecting plate.

[0010] In some embodiments, a slider is slidably mounted on the lower surface of the connecting plate. The slider is near one end of the connecting plate, and one of the rotating shafts is fixed on the side of the slider near the fixed plate. A spring is fixed on the side of the slider away from the rotating shaft, and the other end of the spring is fixed to the lower surface of the connecting plate by a baffle.

[0011] In some embodiments, the angle of the viewing plate is limited by a limiting component.

[0012] In some embodiments, shock-absorbing sleeves are fixed to the inner walls of the through holes of the two fixing plates, and the shock-absorbing sleeves are stepped.

[0013] In some embodiments, a universal bamboo tube is fixed to one side of the slide, and a quick-connect connector for connecting a high-pressure air source is provided at the lower end of the universal bamboo tube.

[0014] Compared with the prior art, this utility model provides a device for repairing the runout of the magnetic extreme surface of ultra-precision machinery, which has the following beneficial effects.

By adopting an online repair method, the optimal precision of the magnetic end face is guaranteed.

[0016] 2. This utility model, by setting a transparent plate, avoids particles from splashing onto the face or eyes of workers when the grinding wheel repairs the magnetic poles, thus preventing discomfort to the workers; by setting a rotating shaft, it is easy to rotate the transparent plate and adjust the angle of the transparent plate so that the transparent plate is placed at the best angle for clearer observation of the magnetic poles.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Reference Figure 1-7 The ultra-precision machine magnetic end face runout repair device includes a repair component 2 for repairing the magnetic end face and a mounting base 1 for installing the repair component 2. The mounting base 1 includes a fixed base 101 fixed on the ultra-precision machine and a sliding component 102 and a feeding component 103 for driving the repair component 2 to move. The repair component 2 is fixed above the sliding component 102 by a mounting ring 104. Repair component 2 includes a motor 201 and a grinding wheel 202 fixed at the output end of the motor 201. The grinding wheel 202 is a diamond grinding wheel 202.

[0028] Understandably, by setting up mounting base 1 and repair component 2, when it is necessary to repair the magnetic pole of the ultra-precision machine, mounting base 1 is fixed on the ultra-precision machine by fixing base 101, so that grinding wheel 202 corresponds to the magnetic pole end face, and the grinding wheel 202 is driven to rotate by motor 201. At the same time, sliding component 102 drives motor 201 and grinding wheel 202 to move, repairing the magnetic pole of the ultra-precision machine. By adopting an online repair method, the best precision of the magnetic pole end face is ensured.

[0029] Specifically, the fixing base 101 includes a vertical plate 1011 and a horizontal plate 1012 fixed to one side of the vertical plate 1011. The vertical plate 1011 and the horizontal plate 1012 are perpendicular to each other. The horizontal plate 1012 is located at the top of the vertical plate 1011. Multiple rows of vertically arranged elongated holes 1013 are opened on the surface of the vertical plate 1011.

[0030] It is understandable that by setting the mounting base 101, multiple bolts are installed on the ultra-precision machine through multiple elongated holes 1013, maintaining the stability of the mounting base 1, thereby avoiding affecting the repair accuracy of the magnetic pole. By setting multiple elongated holes 1013, it is easy to adapt to the use of different models of ultra-precision machines.

[0031] Specifically, the sliding assembly 102 includes two guide rails 1021 fixed to the upper surface of the horizontal plate 1012 and a slide block 1022 sliding on the surface of the two guide rails 1021; The feed assembly 103 includes a threaded post 1031 that rotates on the surface of the horizontal plate 1012 and a moving block 1032 that is threadedly connected to the surface of the threaded post 1031. The other end of the threaded post 1031 rotates on the top of the vertical plate 1011. The moving block 1032 is fixed to the bottom of the slide block 1022. The threaded post 1031 is located between two guide rails 1021. A rotating wheel 1033 is fixed to one end of the threaded post 1031 away from the vertical plate 1011.

[0032] It is understandable that by rotating the threaded column 1031 through the rotating wheel 1033, the moving block 1032 drives the slide block 1022 to slide on the surface of the two guide rails 1021, thereby driving the grinding wheel 202 to repair the magnetic pole.

[0033] Specifically, the mounting ring 104 includes a lower ring body 1041 fixed to the upper surface of the slide block 1022 and an upper ring body 1042 fixed above the lower ring body 1041. The upper ring body 1042, the lower ring body 1041 and the slide block 1022 are respectively provided with a plurality of mounting holes 1043. The upper ring body 1042 and the lower ring body 1041 are fixedly connected by a plurality of bolts and mounting holes 1043, and the upper ring body 1042 and the lower ring body 1041 are fixed by the mounting holes 1043 on the surface of the slide block 1022.

[0034] Understandably, by setting up the upper ring body 1042 and the lower ring body 1041, it is convenient to clamp and fix the motor 201. The engagement of bolts with multiple mounting holes 1043 facilitates simultaneous fixing of the upper ring body 1042, the lower ring body 1041, and the slide 1022. The fixed position of the upper ring body 1042 and the lower ring body 1041 on the surface of the slide 1022 is adjusted to adapt to different types of ultra-precision machines.

[0035] Specifically, a transparent acrylic plate 3 is provided on the upper surface of the upper ring body 1042. The transparent acrylic plate 3 is installed on the upper ring body 1042 via a mounting assembly 4. The mounting assembly 4 includes a connecting plate 401 fixed to the bottom of the transparent acrylic plate 3 and two fixing plates 402 fixed to the upper surface of the upper ring body 1042. The connecting plate 401 rotates on the surface of the two fixing plates 402 via two rotating shafts 403. The two rotating shafts 403 are respectively located at both ends of the connecting plate 401. A slider 404 slides laterally on the lower surface of the connecting plate 401. One of the sliders 404 is near one end of the connecting plate 401. One of the rotating shafts 403 is fixed on the side of the slider 404 near the fixed plate 402, and the other rotating shaft 403 is fixed on the other end of the connecting plate 401. The slider 404 is U-shaped. A spring 406 is fixed on the side of the slider 404 away from the rotating shaft 403. A baffle 405 is fixed on the other end of the spring 406. The baffle 405 is fixed on the lower surface of the connecting plate 401.

[0036] It is understandable that, due to the high precision required when repairing magnetic poles, staff need to observe the repair status of the magnetic poles at close range. The spatter generated during the grinding with the grinding wheel 202 can easily splash onto the staff's face. By setting up the viewing plate 3, it is possible to avoid the particles splashing onto the staff's face or eyes when the grinding wheel 202 repairs the magnetic poles, thus preventing discomfort to the staff. By setting the pivot 403, the viewing plate 3 can be rotated to adjust its angle, allowing it to be positioned at the optimal angle for clearer observation of the magnetic poles. By moving the slider 404, one of the pivots 403 can be disengaged from the fixed plate 402, making it easy to remove the viewing plate 3 for replacement or cleaning, maintaining its light transmission effect and preventing its surface from becoming blurry after prolonged use.

[0037] Specifically, the angle of the transparent plate 3 is limited by the limiting component 5. The limiting component 5 includes a first limiting plate 501 fixed to the bottom of the slider 404 and a plurality of second limiting plates 502. The plurality of second limiting plates 502 are uniformly fixed in an arc shape on the surface of the fixing plate 402 near the slider 404. The arc path of the plurality of second limiting plates 502 is concentric with the through hole on the surface of the fixing plate 402. The length of the rotating shaft 403 located on the side of the slider 404 is greater than the length of the rotating shaft 403 located at one end of the connecting plate 401.

[0038] It is understandable that by setting a first limiting plate 501 and multiple second limiting plates 502, the spring 406 pushes the first limiting plate 501 to insert between the second limiting plates 502, thereby limiting the angle of the transparent plate 3. When it is necessary to rotate the transparent plate 3, the slider 404 is moved, and the sliding distance is such that the first limiting plate 501 disengages from the second limiting plate 502, thereby facilitating the release of the angle limitation on the transparent plate 3.

[0039] Specifically, shock-absorbing sleeves 6 are fixed to the inner walls of the through holes of the two fixing plates 402, and the shock-absorbing sleeves 6 are stepped.

[0040] It is understandable that the vibrations generated when the motor 201 is working and when the grinding wheel 202 is grinding the magnetic poles will cause the viewing plate 3 to vibrate, affecting the observation effect of the viewing plate 3. Therefore, by setting the shock-absorbing sleeve 6, the high-frequency vibrations transmitted to the surface of the viewing plate 3 are reduced.

[0041] Specifically, a universal bamboo tube 7 is fixed on one side of the slide 1022, and a quick-connect connector 701 for connecting a high-pressure air source is provided at the lower end of the universal bamboo tube 7.

[0042] Understandably, by setting up the universal bamboo tube 7 and connecting it to a high-pressure air source via the quick-connect connector 701, the angle of the universal bamboo tube 7 can be adjusted to simultaneously blow air onto the grinding wheel 202 and the magnetic pole, thereby cooling them down and preventing the grinding wheel 202 from generating high temperatures that could affect the repair accuracy.

[0043] In this invention, when the magnetic poles of an ultra-precision machine need to be repaired, multiple bolts are installed on the ultra-precision machine through multiple elongated holes 1013 to maintain the stability of the mounting base 1, so that the grinding wheel 202 corresponds to the magnetic pole end face. The motor 201 drives the grinding wheel 202 to rotate, and the rotating wheel 1033 rotates the threaded column 1031, thereby causing the moving block 1032 to drive the slide 1022 to slide on the surface of the two guide rails 1021, so that the grinding wheel 202 repairs the magnetic pole. During the repair, the universal bamboo tube 7 blows air on the grinding wheel 202 and the magnetic pole to cool them down and prevent the high temperature generated by the grinding wheel 202 from affecting the repair accuracy. With the help of the viewing plate 3, particles are prevented from splashing onto the face or eyes of the workers when the grinding wheel 202 repairs the magnetic pole, so as to avoid causing discomfort to the workers. By adopting an online repair method, the best accuracy of the magnetic pole end face is guaranteed.
