Description

Technical Field

[0001] This utility model relates to the field of coil grinding technology, specifically to a conformal floating voltage regulator coil grinding production line, which is particularly suitable for continuous rough grinding, fine grinding and polishing operations that require ensuring the surface smoothness of the coil and the contact performance of the carbon brush. Background Technology

[0002] The rapid development of the power equipment manufacturing industry has placed higher precision requirements on the core components of voltage regulators, with coil surface treatment being particularly critical. As a key carrier of current transmission, the surface smoothness of the coil directly affects the insulation performance of the equipment and determines the quality of its dynamic contact with the carbon brush. Currently, the industry commonly uses a sequential manual grinding process: workers use hand-held grinding wheels to perform rough grinding, fine grinding, and polishing in sequence. However, the coil surface has irregular undulations, and rigid grinding tools cannot adaptively conform to the surface, leading to over-grinding or under-grinding in certain areas. Over-grinding weakens the cross-sectional area of ​​the copper wire, affecting conductivity, while under-grinding leaves oxide residue, forming insulation spots. More seriously, surface unevenness causes fluctuations in the carbon brush contact area, leading to increased contact resistance, abnormal heating, and even arcing, significantly shortening the equipment's lifespan. Furthermore, the highly conductive metal dust generated during copper alloy grinding permeates the working area and easily adheres to the coil gaps, causing short-circuit faults. The need for repeated clamping and positioning during multi-process transitions further amplifies processing errors. Summary of the Invention

[0007] Furthermore, the conformal floating assembly includes a movable component, a conformal tensioning wheel, a spring, and a lifting eye screw.

[0009] Furthermore, a set of conformal floating grinding devices is provided at the connection of the two adjacent arc-shaped conveyor belts and between the arc-shaped conveyor belt and the horizontal conveyor belt, and the conformal grinding belt in each set of floating grinding mechanisms is set with different roughness.

[0011] Furthermore, it also includes a negative pressure dust removal mechanism, used for dust removal during the grinding process of the voltage regulator coil.

[0012] Furthermore, the negative pressure dust removal mechanism includes a centrifugal fan, rotating blades, a debris collection bag, and a centrifugal pipe.

[0016] Beneficial effects:

[0017] This invention utilizes multiple sets of conformal floating grinding devices and a conveying mechanism.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments.

[0029] It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] As attached Figure 1 and attached Figure 2 As shown, this invention provides a conformal floating voltage regulator coil grinding production line, including a frame 500, multiple sets of conformal floating grinding devices and a conveying mechanism 400 arranged on the frame 500. Each set of conformal floating grinding devices corresponds to a processing station and includes a floating grinding mechanism 100, a negative pressure dust removal mechanism 200 and an automatic clamping mechanism 300.

[0031] The voltage regulator coil 28 to be processed is transported by the conveying mechanism 400. When it passes the corresponding station of the conformal floating grinding device, the automatic clamping mechanism 300 is used to position the voltage regulator coil 28, the floating grinding mechanism 100 is used to grind the positioned voltage regulator coil 28, and the negative pressure dust removal mechanism 200 is used to remove dust during the grinding process of the voltage regulator coil 28.

[0032] Specifically, in this embodiment, three sets of conformal floating grinding devices are provided on one side of the conveying mechanism 400, corresponding to three processing stations: rough grinding station 1, fine grinding station 2, and polishing station 3. The voltage regulator coil 28 to be processed is transported on the conveying mechanism 400 and output after rough grinding, fine grinding, and polishing at the three processing stations. Understandably, the processing stations can be set according to actual needs; that is, processing stations can be added or removed in the conveying direction of the conveying mechanism 400, which corresponds to increasing or decreasing the number of conformal floating grinding devices. By setting up a full-process production line, the entire process of rough grinding, fine grinding, and polishing is realized, thus eliminating positioning errors during process transitions and improving positioning accuracy and processing efficiency.

[0033] As attached Figure 3 As shown, the floating grinding mechanism 100 includes a profile frame 7, a first servo motor 9, a drive wheel 10, a conformal grinding belt 11, a driven wheel 14, a fixed plate 16, and a conformal floating assembly. The profile frame 7 is mounted on the frame 500.

[0034] A first servo motor 9 and a fixed plate 16 are mounted on the profile frame 7. A driving wheel 10 and a driven wheel 14 are mounted on the fixed plate 16. The output shaft of the first servo motor 9 is connected to the driving wheel 10. A conformal grinding belt 11 is wound around the outer circumference of both the driving wheel 10 and the driven wheel 14. A conformal floating component is also mounted on the fixed plate 16. The conformal floating component acts on the conformal grinding belt 11 to control the conformal grinding belt 11 to adhere tightly to the voltage regulator coil 28 during processing, thereby achieving dynamic compensation of the curved surface.

[0035] Specifically, the conformal floating component in the floating grinding mechanism 100 dynamically compensates for surface undulations during the grinding process of the voltage regulator coil 28, ensuring that the conformal grinding belt 11 is in close contact with the surface of the voltage regulator coil 28, thus ensuring constant grinding pressure, eliminating over-grinding / under-grinding phenomena, and ensuring reliable contact of the entire area of ​​the voltage regulator coil 28, thereby guaranteeing the reliability and effectiveness of the processing.

[0036] Furthermore, the conformal floating assembly includes a movable member 12, a conformal tensioning wheel 13, a spring 15, and a lifting eye screw 17. The fixed plate 16 also has the movable member 12 and the lifting eye screw 17. The lifting eye screw 17 is located between the driving wheel 10 and the driven wheel 14, and movable members 12 are respectively located on opposite sides of the lifting eye screw 17. The middle of the movable member 12 is hinged to the fixed plate 16. The conformal tensioning wheel 13 is located at the end of the movable member 12 away from the lifting eye screw 17, and the conformal tensioning wheel 13 acts on the conformal grinding belt 11. A spring 15 is located between the end of the movable member 12 near the lifting eye screw 17 and the lifting eye screw 17.

[0037] Specifically, the first servo motor 9 is mounted on the profile frame 7 via the motor support frame 8. The drive wheel 10 is driven by the first servo motor 9 and, under the action of the driven wheel 14, drives the conformal grinding belt 11 to rotate. During grinding, the conformal grinding belt 11 contacts the voltage regulator coil 28. When the surface undulation of the voltage regulator coil 28 is ±10mm, the movable part 12, under the action of the spring 15, pushes the conformal tension wheel 13 to swing around the hinge point, achieving dynamic surface compensation for the conformal grinding belt 11, so that the conformal grinding belt 11 fits tightly against the surface of the voltage regulator coil 28, ensuring the reliability of the processing.

[0038] In this embodiment, the conformal floating assembly forms an asymmetrical quadrilateral floating structure through the conformal grinding belt 11 under the action of the driving wheel 10, the driven wheel 14 and the two conformal tensioning wheels 13. The conformal floating assembly is supported by two sets of moving parts 12 and a fixed plate 16 as a common base. The tension of the conformal grinding belt 11 is linked by the two springs 15 through the eye bolts 17, which ensures the reliability of the conformal floating assembly.

[0039] Continue reading Figure 1As shown, the conveying mechanism 400 includes multiple arc-shaped conveyor belts 4, a horizontal conveyor belt 5, and an inclined conveyor belt 6 connected in sequence. The multiple arc-shaped conveyor belts 4 are connected in sequence and then connected in series with the horizontal conveyor belt 5 to form a figure-9 structure. The inclined conveyor belt 6 is located at the end of the horizontal conveyor belt 5 along the conveying direction to facilitate the discharge of the voltage regulator coil 28 after processing.

[0040] Furthermore, a set of conformal floating grinding devices is provided at the connection points of two adjacent arc-shaped conveyor belts 4 and the horizontal conveyor belt 5, which can realize multi-station grinding processing and reduce installation space. The conformal grinding belts 11 in the conformal floating grinding device are respectively set with different roughness to meet different processing procedures;

[0041] Specifically, the spacing between processing stations is 500mm to 800mm. At coarse grinding station 1, the conformal grinding belt 11 uses a 40-mesh abrasive belt; at fine grinding station 2, a 240-mesh abrasive belt; and at polishing station 3, a cloth belt. The spacing between processing stations is set to 600mm, ensuring reliable coarse grinding, fine grinding, and polishing of the voltage regulator coil 28. The arc-shaped conveyor belt 4 can adopt a 90° arc structure, and the inclination angle of the inclined conveyor belt 6 is 0° to 90°, preferably 30°. The voltage regulator coil 28 is input via the first 90° arc-shaped conveyor belt 4, sequentially conveyed to coarse grinding station 1, fine grinding station 2, and polishing station 3 via other arc-shaped conveyor belts 4, and finally output via the horizontal conveyor belt 5 and the inclined conveyor belt 6.

[0042] In this embodiment, by setting up three processing stations for coarse grinding, fine grinding and polishing to operate continuously, the processing time of a single voltage regulator coil 28 is shortened. Combined with the configuration of a conformal grinding belt 11 composed of abrasive belts and cloth belts of different grit sizes, the polishing efficiency is improved and the life of the conformal grinding belt 11 is extended.

[0043] As attached Figure 4 As shown, the negative pressure dust removal mechanism 200 includes a centrifugal fan 25, rotating blades 26, a debris collection bag 27, and a centrifugal pipe 29. The centrifugal fan 25 is connected to the centrifugal pipe 29 and the debris collection bag 27 at its end. The rotating blades 26 are installed inside the centrifugal pipe 29, and the opening of the centrifugal pipe 29 corresponds to the position of the conveying mechanism 400.

[0044] Specifically, the centrifugal fan 25 creates a negative pressure zone of 0.5kPa to 1.2kPa 100mm above the grinding point of the arc-shaped conveyor belt 4 of the conveying mechanism 400. The direction of the negative pressure airflow is perpendicular to the grinding surface, and the coverage area of ​​the negative pressure zone coincides with the grinding trajectory of the conformal grinding belt 11. The debris is drawn into the debris collection bag 27 through the centrifugal pipe 29. By setting up the negative pressure dust removal mechanism 200, a high-speed airflow of 18m / s in the axial direction can be formed at the grinding point to capture conductive dust in real time during the grinding process. The dust collection efficiency is very high, and the dust concentration in the working area can be stably controlled at 2mg / m³.3 The following methods completely eliminate the risk of metal dust explosion and prevent electrical short circuits, further ensuring the reliability of the work.

[0045] participate Figure 5 and Figure 6 As shown, the automatic clamping mechanism 300 includes a second servo motor 18, a lead screw lifting assembly 19, a third servo motor 20, a transmission belt 21, a worm gear assembly 22, a variable diameter chuck 23, and a worktable 24. The second servo motor 18 is mounted on the frame 500 and is connected to the lead screw lifting assembly 19. The lead screw of the lead screw lifting assembly 19 is connected to the worktable 24. The worm gear assembly 22 is mounted on the worktable 24, and the variable diameter chuck 23 is mounted on the worktable 24 and connected to the worm wheel of the worm gear assembly 22. The third servo motor 20 is mounted on the worktable 24, and its output shaft is connected to the worm of the worm gear assembly 22 via the transmission belt 21. The variable diameter chuck 23 cooperates with the voltage regulator coil 28 to be processed for positioning.

[0046] Furthermore, the worktable 24 includes an upper plate 241, a lower plate 242, and a support 243. The upper plate 241 and the lower plate 242 are arranged opposite each other, and their ends are connected by the support 243, which facilitates installation and provides installation space for the worm gear assembly 22 and the variable diameter chuck 23, resulting in a compact structure and reliable fit. The lower plate 242 is connected to the end of the lead screw of the lead screw lifting assembly 19, and the variable diameter chuck 23 is installed on the upper plate 241. The worm gear assembly 22 is arranged in the space between the upper plate 241 and the lower plate 242. The worm of the worm gear assembly 22 passes through the support 243. The third servo motor 20 is located on the side of the support 243 away from the variable diameter chuck 23 and is connected to the worm through a transmission belt 21.

[0047] In this embodiment, the stroke of the lead screw lifting assembly 19 is 0mm to 500mm. The second servo motor 18 drives the lead screw lifting assembly 19 to work, and drives the worktable 24 and the worm gear assembly 22 and the variable diameter chuck 23 on the worktable 24 to perform a translational movement as a whole. The third servo motor 20 drives the worm gear assembly 22 to work, and the worm gear assembly 22 drives the variable diameter chuck 23 to rotate, so that the variable diameter chuck 23 can cooperate and be positioned with the conformal grinding belt 11 to achieve reliable grinding processing.

[0048] Furthermore, a vision inspection component 600 is also provided on the frame 500. The vision inspection component 600 corresponds to the position of the conformal floating grinding device and is used to inspect the voltage regulator coil 28 to be processed and transport it to the processing station.

[0049] In this embodiment, the conformal floating polishing device is located above the arc-shaped conveyor belt 4 in the conveying mechanism 400, the automatic clamping mechanism 300 is located below the arc-shaped conveyor belt 4, the floating polishing mechanism 100 and the negative pressure dust removal mechanism 200 are located on opposite sides of the arc-shaped conveyor belt 4, and the vision inspection component 600 is located below the negative pressure dust removal mechanism 200. This makes the overall structure compact and also ensures the reliability of the cooperation between the various mechanisms.

[0050] Specifically, the vision inspection component 600 can employ a vision sensor. When the vision sensor detects that the voltage regulator coil 28 to be processed has reached the processing station gap, the second servo motor 18 drives the lead screw lifting component 19 to rise by 200mm, and drives the variable diameter chuck 23 to rise, so that the variable diameter chuck 23 reaches the inner hole of the voltage regulator coil 28; the third servo motor 20 drives the worm gear assembly 22 to work through the transmission belt 21, and drives the variable diameter chuck 23 to fix the voltage regulator coil 28 with a clamping force of 80N. The floating grinding mechanism 100 starts working, and acts directly on the conformal grinding belt 11 through the conformal tensioning wheel 13. The conformal grinding belt 11 performs conformal grinding on the surface of the voltage regulator coil 28. After processing, the automatic clamping mechanism 300 controls the variable diameter chuck 23 to release the coil, and the processed voltage regulator coil 28 is transferred to the inclined conveyor belt 6 via the horizontal conveyor belt 5 and slides out.

[0051] In this new type of machine, an automatic loading mechanism 300 replaces manual operation and is combined with a vision inspection component 600 for visual positioning (with a repeatability of ±0.1mm). This enables fully unmanned operation of gripping, lifting, and rotating the voltage regulator coil 28. The loading time is much longer than that of manual loading, which improves product consistency and safety, as well as positioning accuracy and processing efficiency.

[0052] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
