Description

Technical Field

[0001] This invention relates to the field of workpiece grinding, and in particular to a grinding and shaping device and its method for internal processing of transformers. Background Technology

[0002] With the development of industrial technology, modern workpiece grinding technology has become more and more sophisticated. During the laying of remote circuit systems, many transformers are used. Many iron cores and coils are installed inside the transformers. If there are metal burrs or other debris in the installation slots, the installation will be difficult. This requires a grinding device inside the transformer. As disclosed in patent number 201922501905.8, a device for polishing the casing of a transformer used in toys includes a worktable. A first motor is fixedly installed in the middle of the bottom of the worktable. The output shaft of the first motor passes through the worktable and is fixedly installed on a turntable. The casing is placed on the top of the turntable. Two electric telescopic rods are fixedly installed on the top of the worktable. The output ends of the two electric telescopic rods are fixed to the same fixed plate. A round rod is fixedly installed in the middle of the bottom of the fixed plate, and a clamping mechanism is rotatably provided at the bottom end of the round rod. A second motor is fixedly installed on the bottom of the fixed plate, and a polishing wheel is fixedly installed on the output shaft of the second motor. Two symmetrical sliding rods pass through the top of the fixed plate. This utility model solves the problems of low efficiency, uneven edges, and poor quality in traditional polishing of toy transformer casings. The device has several drawbacks. First, it is cumbersome to operate when loading and unloading workpieces, and the sharp mechanical corners can easily cause workers to bump into them, posing a certain degree of danger. Second, previous groove grinding devices required an electronic system to program the grinding path. If this system is damaged, mechanical personnel cannot repair it, and it wastes a lot of manpower and time for programming technicians to come and repair it. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a grinding and forming device and its usage method for internal processing of transformers. In use, two transformer modules to be processed are inserted into a shallow groove at the top of a loading plate. Then, a locking plate is installed on the top of a locking column. At this point, the operator releases the locking column, and the locking column is tightened downwards by the elastic force of a tension rod. Simultaneously, a reduction motor drives a gear disc to rotate via a reduction gear, causing the central column to rotate synchronously with the gear disc. The torsion ring at the top of the central column and the loading plate rotate 180 degrees back and forth, allowing the transformer modules to alternately enter the processing station, thus avoiding the need for operators to manually load and unload workpieces inside complex mechanical devices.

A grinding rod is inserted through the inner side of the path groove. A stepper motor is also fixedly installed at the top of the cantilever bridge. A slot frame is installed at the output end of the stepper motor. The grinding rod is inserted through the inner side of the slot frame and is connected to a torsional grinding mechanism.

[0005] Furthermore, the locking assembly includes two shallow grooves at the top of the filling plate, the grooves being two centimeters deep, and the outline of the grooves matching the cross-section of the transformer module. The top of the filling plate is also provided with four locking posts, each with a locking plate at its top. The locking plates engage with the top surface of the transformer module. The locking posts are connected to the insertion mechanism, and a blocking mechanism is also provided in the middle of the transformer module.

[0006] Furthermore, the insertion mechanism includes a tension rod at the bottom of the locking post, the tension rod is slidably inserted into the loading plate, a locking spring is also fitted on the outside of the tension rod, a plunger hole is provided at the top of the locking post, and a rubber plunger matching the plunger hole is provided at the bottom of the locking plate.

[0007] Furthermore, the blocking mechanism includes a vertical plate in the middle of the central column, a positioning horizontal plate at the top of the vertical plate, the positioning horizontal plate being inserted between the transformer modules, and the transformer modules being tightly attached to the side wall of the positioning horizontal plate.

[0008] Furthermore, the angle conversion mechanism includes a gear disk on the outside of the central column, a reduction gear on one side of the gear disk, the reduction gear and the gear disk meshing with each other, and the reduction gear is installed on the output end of the reduction motor, which is fixed on the top surface of the base plate.

[0009] Furthermore, the linear propulsion assembly includes positioning shaft seats at both ends of the processing table, a positioning roller is rotatably mounted on one side of the positioning shaft seat, the positioning rollers are connected by a positioning belt, the positioning roller at the front end is mounted on the output end of the positioning motor, and the bottom surface of the platform is connected to the positioning belt.

[0010] Furthermore, the retractable elastic mechanism includes return springs on both sides of the cantilever bridge, with the ends of the return springs connected to the side walls of the cantilever bridge and the path plate, respectively. Electromagnets are provided on the side walls of the cantilever bridge and the path plate.

[0011] Furthermore, both ends of the grinding rod are provided with grinding heads, the diameter of which matches the shallow groove of the iron core. The end of the grinding head is provided with a telescopic square rod inserted into the grinding rod, and a retractable soft spring is provided in the cavity in the middle of the grinding rod, which is connected to the end face of the telescopic square rod.

[0012] Furthermore, the torsional grinding mechanism includes a sliding groove at the top of the cantilever bridge, a grinding motor is slidably installed on the inner side of the sliding groove, a drive wheel is installed at the output end of the grinding motor, a driven wheel is installed on the outer side of the grinding rod, the drive wheel and the driven wheel are connected by a drive belt, a traction plate is provided at the top of the platform, and the traction plate and the side wall of the grinding motor are connected by a traction spring.

[0013] A method for using a grinding and shaping device for internal processing of a transformer includes the following steps: S1. Insert the two transformer modules to be processed into the shallow groove at the top of the loading plate, and then install the locking plate on the top of the locking column. At this time, the operator loosens the locking column and allows the locking column to apply locking force downward through the elastic force of the tension rod. At this time, the reduction motor drives the gear disk to rotate through the reduction gear, and the center column will rotate synchronously with the gear disk. The torsion ring at the top of the center column and the loading plate rotate back and forth 180 degrees to allow the transformer modules to enter the processing station in turn, avoiding the operator having to load and unload workpieces inside the complex mechanical device. S2. The positioning motor drives the positioning belt through the positioning roller, and the platform slides back and forth with the positioning belt. The platform and the two path plates at its ends move forward and insert into the middle of the two transformer modules. At this time, the electromagnet at the bottom of the path plate is de-energized. The path plate expands to both sides through the two reset springs until the path plate is attached to the side wall of the transformer module. While the path plate expands to both sides, it pulls the grinding head out from inside the grinding rod. The stepper motor drives the slot frame to rotate, which makes the grinding rod slide along the path slot. The grinding head can then be inserted into the inside of the shallow slot of the iron core for grinding. S3. As the grinding rod slides back and forth along the path groove, the grinding motor drives the driven wheel to rotate through the drive wheel and drive belt. The grinding rod rotates together with the driven wheel, so the grinding rod rotates while being pushed forward, which improves the grinding efficiency of the grinding head. The traction spring pulls the grinding motor to apply elastic force to the rear of the sliding groove, so the drive belt can always maintain sufficient tension.

[0014] The beneficial effects of this invention are: Firstly, when using this device, the two transformer modules to be processed are inserted into the shallow groove at the top of the loading plate, and then the locking plate is installed on the top of the locking column. At this time, the operator releases the locking column and allows the locking column to apply locking force downward through the elastic force of the tension rod. At this time, the reduction motor drives the gear disk to rotate through the reduction gear, and then the central column will rotate synchronously with the gear disk. The torsion ring at the top of the central column and the loading plate rotate back and forth 180 degrees to allow the transformer modules to enter the processing station in turn, avoiding the need for the operator to load and unload workpieces inside the complex mechanical device.

[0015] Secondly, the positioning motor drives the positioning belt through the positioning roller, and the platform slides back and forth with the positioning belt. The platform and the two path plates at its ends move forward and insert into the middle of the two transformer modules. At this time, the electromagnet at the bottom of the path plate is de-energized, and the path plate expands to both sides through the two reset springs until the path plate is attached to the side wall of the transformer module. While the path plate expands to both sides, it pulls the grinding head out from inside the grinding rod. The stepper motor drives the slot frame to rotate, which makes the grinding rod slide along the trajectory of the path slot. The grinding head can then be inserted into the shallow slot of the iron core for grinding.

[0016] Thirdly, as the grinding rod slides back and forth along the path groove, the grinding motor drives the driven wheel to rotate through the drive wheel and drive belt. The grinding rod rotates together with the driven wheel, thus the grinding rod rotates while being pushed forward, which improves the grinding efficiency of the grinding head. The traction spring pulls the grinding motor to apply elastic force to the rear of the sliding groove, so the drive belt can always maintain sufficient tension. Attached Figure Description

[0028] Reference Figures 1 to 8The diagram shows a grinding and forming device for internal processing of a transformer, comprising a base plate 1. A central column 101 is rotatably mounted on the top of the base plate 1. Two surrounding beams 102 are mounted on the top of the central column 101, and a torsion ring 103 is mounted on the top of each surrounding beam 102. Two loading plates 3 are detachably mounted on the top of the torsion ring 103. Two transformer modules 301 are fixedly mounted on the top of the loading plates 3, and shallow core grooves 302 are provided on the upper sidewalls of the transformer modules 301. The loading plates 3 are provided with... A locking assembly matching the transformer module 301 is provided. The central column 101 is connected to the angle conversion mechanism. A processing table 4 is provided on one side of the base plate 1. Two transport guide rails 401 are provided at the top of the processing table 4, and a transport slider 402 is slidably mounted on the transport guide rails 401. A loading platform 403 is provided at the top of the transport slider 402. The loading platform 403 is connected to the linear propulsion assembly. A grinding mechanism is also provided at the top of the loading platform 403. The grinding mechanism includes components fixed to the top of the loading platform 403. The cantilever bridge 6 has two path plates 7 on both sides. An expansion guide rod 8, which slides through the bottom of the path plate 7 and is inserted into the inner side of the cantilever bridge 6, is provided between the path plate 7 and the expansion guide rod 8. Two path grooves 701 are provided on the side wall of the path plate 7, and a grinding rod 10 is inserted through the inner side of the path groove 701. A stepper motor 9 is fixedly installed at the top of the cantilever bridge 6. A slot frame 901 is installed at the output end of the stepper motor 9, and the grinding rod 10 is inserted through the inner side of the slot frame 901. The grinding rod 10 is connected to the torsional grinding mechanism. The platform 403 and the two path plates 7 at its ends are pushed forward and inserted between the two transformer modules 301. The stepper motor 9 drives the slot frame 901 to rotate, which in turn causes the grinding rod 10 to slide along the trajectory of the path slot 701. The grinding head 1001 can then be inserted into the inside of the iron core shallow slot 302 to perform grinding operations. Compared with the path variable programming grinding operation of the prior art, when this device is damaged, mechanical technicians can repair it immediately.

[0029] like Figure 1 , 3 As shown, the locking assembly includes two shallow grooves at the top of the filling plate 3, the grooves being two centimeters deep, and their outlines matching the cross-section of the transformer module 301. The top of the filling plate 3 is also provided with four locking posts 303, and the top of each locking post 303 is provided with a locking piece 304. The locking piece 304 engages with the top surface of the transformer module 301. The locking posts 303 are connected to the insertion mechanism, and a blocking mechanism is also provided in the middle of the transformer module 301. When two transformer modules 301 to be processed are inserted into the shallow grooves at the top of the filling plate 3, the locking piece 304 will press down on the top of the transformer module 301 to prevent the transformer module 301 from shaking during operation.

[0030] like Figure 1 , 3 As shown, the insertion mechanism includes a tension rod 305 at the bottom of the locking post 303. The tension rod 305 slides through the filling plate 3. A locking spring is also fitted on the outside of the tension rod 305. A plunger hole is provided at the top of the locking post 303, and a rubber plunger matching the plunger hole is provided at the bottom of the locking plate 304. At this time, the operator can loosen the locking post 303 and let the locking post 303 apply a locking force downward through the elastic force of the tension rod 305. The locking plate 304 can be pulled out at any time when installation is difficult.

[0031] like Figure 1 , 3 As shown, the blocking mechanism includes a vertical plate 2 in the middle of the central column 101. A positioning horizontal plate 201 is provided at the top of the vertical plate 2. The positioning horizontal plate 201 is inserted between the transformer modules 301, and the transformer modules 301 are in close contact with the side wall of the positioning horizontal plate 201. The close contact of the transformer modules 301 with the positioning horizontal plate 201 increases the stability of the two transformer modules 301.

[0032] like Figure 1 , 2 As shown, the angle conversion mechanism includes a gear disk 5 on the outside of the central column 101. A reduction gear 501 is provided on one side of the gear disk 5. The reduction gear 501 and the gear disk 5 mesh with each other, and the reduction gear 501 is installed on the output end of the reduction motor 502. The reduction motor 502 is fixed on the top surface of the base plate 1. The reduction motor 502 drives the gear disk 5 to rotate through the reduction gear 501, and then the central column 101 will rotate synchronously with the gear disk 5. The torsion ring 103 and the loading plate 3 at the top of the central column 101 rotate back and forth 180 degrees to allow the transformer module 301 to enter the processing station in turn.

[0033] like Figure 1 , 5 As shown, the linear propulsion assembly includes positioning shaft seats 404 at both ends of the processing table 4. Positioning rollers 405 are rotatably mounted on one side of the positioning shaft seats 404. The positioning rollers 405 are connected to each other by a positioning belt 406. The front positioning roller 405 is mounted on the output end of the positioning motor 407. The bottom surface of the platform 403 is connected to the positioning belt 406. The positioning motor 407 drives the positioning belt 406 to rotate through the positioning rollers 405, and the platform 403 slides back and forth with the positioning belt 406.

[0034] like Figure 1 , 6As shown in Figure 8, the retractable elastic mechanism includes return springs 801 on both sides of the cantilever bridge 6. The ends of the return springs 801 are respectively connected to the side walls of the cantilever bridge 6 and the path plate 7. Electromagnets are provided on the side walls of the cantilever bridge 6 and the path plate 7. The platform 403 and the two path plates 7 at its ends are pushed forward and inserted into the middle of the two transformer modules 301. At this time, the electromagnet at the bottom of the path plate 7 is de-energized, and the path plate 7 expands to both sides through the two return springs 801 until the path plate 7 is attached to the side wall of the transformer module 301.

[0035] like Figure 1 , 7 As shown, both ends of the grinding rod 10 are provided with grinding heads 1001. The diameter of the grinding head 1001 matches the shallow groove 302 of the iron core. The end of the grinding head 1001 is provided with a telescopic square rod 1002 inserted in the grinding rod 10. A retractable soft spring is provided in the cavity in the middle of the grinding rod 10. The retractable soft spring is connected to the end face of the telescopic square rod 1002. While the path plate 7 expands to both sides, it pulls the grinding head 1001 out of the grinding rod 10, so that the grinding head 1001 is close to the inner wall of the shallow groove 302 of the iron core.

[0036] like Figure 1 , 6 As shown, the torsional grinding mechanism includes a sliding groove 601 at the top of the cantilever bridge 6. A grinding motor 602 is slidably mounted on the inner side of the sliding groove 601. A drive wheel 603 is mounted on the output end of the grinding motor 602. A driven wheel 607 is mounted on the outer side of the grinding rod 10. The drive wheel 603 and the driven wheel 607 are connected by a drive belt 604. A traction plate 606 is provided at the top of the platform 403. The traction plate 606 and the side wall of the grinding motor 602 are connected by a traction spring 605. Next, as the grinding rod 10 slides back and forth along the path groove 701, the grinding motor 602 drives the driven wheel 607 to rotate through the drive wheel 603 and drive belt 604. The grinding rod 10 rotates together with the driven wheel 607, so the grinding rod 10 rotates while being pushed forward, which improves the grinding efficiency of the grinding head 1001. The traction spring 605 pulls the grinding motor 602 to apply elastic force to the rear of the sliding groove 601, so the drive belt 604 can always maintain sufficient tension.

[0037] A method for using a grinding and shaping device for internal processing of a transformer includes the following steps: S1. Insert the two transformer modules 301 to be processed into the shallow groove at the top of the loading plate 3, and then install the locking plate 304 onto the top of the locking column 303. At this time, the operator releases the locking column 303 and applies locking force downward through the elastic force of the tension rod 305. At this time, the reduction motor 502 drives the gear disk 5 to rotate through the reduction gear 501, and the center column 101 will rotate synchronously with the gear disk 5. The torsion ring 103 at the top of the center column 101 and the loading plate 3 rotate back and forth 180 degrees to allow the transformer modules 301 to enter the processing station in turn, avoiding the operator from loading and unloading workpieces inside the complex mechanical device. S2. Positioning motor 407 drives positioning belt 406 to rotate via positioning roller 405, and platform 403 slides back and forth with positioning belt 406. Platform 403 and two path plates 7 at its ends move forward and insert into the middle of two transformer modules 301. At this time, the electromagnet at the bottom of path plate 7 is de-energized. Path plate 7 expands to both sides through two reset springs 801 until path plate 7 is attached to the side wall of transformer module 301. While path plate 7 expands to both sides, it pulls grinding head 1001 out from inside grinding rod 10. Stepper motor 9 drives slot frame 901 to rotate while grinding rod 10 slides along the trajectory of path slot 701. Grinding head 1001 can then be inserted into the inside of iron core shallow slot 302 for grinding operation. S3. As the grinding rod 10 slides back and forth along the path groove 701, the grinding motor 602 drives the driven wheel 607 to rotate through the drive wheel 603 and drive belt 604. The grinding rod 10 rotates together with the driven wheel 607, so the grinding rod 10 rotates while being pushed forward, which improves the grinding efficiency of the grinding head 1001. The traction spring 605 pulls the grinding motor 602 to apply elastic force to the rear of the sliding groove 601, so the drive belt 604 can always maintain sufficient tension.

[0038] Working principle: The stage 403 and its two end path plates 7 are pushed forward and inserted between the two transformer modules 301. The stepper motor 9 drives the slot frame 901 to rotate, causing the grinding rod 10 to slide along the path slot 701. The grinding head 1001 can then be inserted into the shallow slot 302 of the iron core for grinding. Compared with the grinding operation of the existing path variable programming, this device can be repaired immediately by mechanical technicians when damaged. The two transformer modules 301 to be processed are inserted into the shallow slot at the top of the loading plate 3, and the locking plate 304 will press down the transformer. At the top of the transformer module 301, to prevent the transformer module 301 from shaking during operation, the operator releases the locking pin 303 and applies locking force downward through the elastic force of the tension rod 305. The locking plate 304 can be pulled out at any time if installation is difficult. The transformer module 301 is tightly attached to the positioning plate 201, increasing the stability of the two transformer modules 301. The reduction motor 502 drives the gear disk 5 to rotate through the reduction gear 501, and the center column 101 will rotate synchronously with the gear disk 5. The torsion ring 103 at the top of the center column 101 and the loading plate 3... The transformer module 301 is rotated 180 degrees to enter the processing station. The positioning motor 407 drives the positioning belt 406 through the positioning roller 405, and the platform 403 slides back and forth with the positioning belt 406. The platform 403 and the two path plates 7 at its ends are pushed forward and inserted between the two transformer modules 301. At this time, the electromagnet at the bottom of the path plate 7 is de-energized, and the path plate 7 expands to both sides through the two return springs 801 until the path plate 7 is attached to the side wall of the transformer module 301. While the path plate 7 is expanding to both sides, the grinding head 1001 is moved from the grinding position. As the rod 10 is pulled outward, the grinding head 1001 is pressed against the inner wall of the shallow groove 302 of the iron core. While the grinding rod 10 slides back and forth along the path groove 701, the grinding motor 602 drives the driven wheel 607 to rotate through the drive wheel 603 and drive belt 604. The grinding rod 10 rotates together with the driven wheel 607, so the grinding rod 10 rotates while being pushed forward, which improves the grinding efficiency of the grinding head 1001. The traction spring 605 pulls the grinding motor 602 to apply elastic force to the rear of the sliding groove 601, so the drive belt 604 can always maintain sufficient tension.

[0039] The above description is merely a preferred embodiment of the present invention and does not constitute any limitation on the technical scope of the present invention. Therefore, any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.

10. The polishing and forming device for internal processing of a transformer and the method of using according to any one of claims 1-9, characterized in that, Includes the following steps: S1. Insert the two transformer modules (301) to be processed into the shallow groove at the top of the loading plate (3), and then install the locking plate (304) on the top of the locking column (303). At this time, the operator loosens the locking column (303) and allows the locking column (303) to apply locking force downward through the elastic force of the tension rod (305). At this time, the geared motor (502) drives the gear disk (5) to rotate through the reduction gear (501), and then the center column (101) will rotate synchronously with the gear disk (5). The torsion ring (103) at the top of the center column (101) and the loading plate (3) rotate back and forth 180 degrees to allow the transformer modules (301) to enter the processing station in turn, avoiding the operator from loading and unloading workpieces inside the complex mechanical device. S2. The positioning motor (407) drives the positioning belt (406) to run through the positioning roller (405), and the platform (403) slides back and forth with the positioning belt (406). The platform (403) and the two path plates (7) at its ends move forward and insert into the middle of the two transformer modules (301). At this time, the electromagnet at the bottom of the path plate (7) is de-energized, and the path plate (7) expands to both sides through the two reset springs (801) until the path plate (7) is attached to the side wall of the transformer module (301). While the path plate (7) expands to both sides, it pulls the grinding head (1001) out from inside the grinding rod (10). The stepper motor (9) drives the slot frame (901) to rotate, and at the same time, it makes the grinding rod (10) slide along the trajectory of the path slot (701). The grinding head (1001) can then be inserted into the inside of the iron core shallow slot (302) for grinding. S3. As the grinding rod (10) slides back and forth along the path groove (701), the grinding motor (602) drives the driven wheel (607) to rotate through the drive wheel (603) and drive belt (604). The grinding rod (10) rotates together with the driven wheel (607). Thus, the grinding rod (10) rotates while being pushed forward, which improves the grinding efficiency of the grinding head (1001). The traction spring (605) pulls the grinding motor (602) to apply elastic force to the rear of the sliding groove (601), so that the drive belt (604) can always maintain sufficient tension.
