Description

Technical Field

[0001] This invention relates to the field of iron core surface treatment technology, specifically to an iron core surface treatment process. Background Technology

[0002] The iron core assembly is assembled and processed from three parts. After processing, the surface needs to be electroplated with zinc-nickel alloy. The middle section is made of SUS304 stainless steel. Direct electroplating with zinc-nickel alloy is not easy and will result in spots and peeling. During the preparation process, it was found that sandblasting, followed by overall electroplating with chemical nickel, and finally electroplating with zinc-nickel alloy, effectively solved the problems of spots and peeling of the iron core surface coating. However, the existing preparation process and equipment cannot easily and continuously perform sandblasting on the iron core, and the electroplating process cannot be carried out in a timely manner after sandblasting. The intermittent process greatly reduces the preparation efficiency. Therefore, a device is needed to solve the above problems. Summary of the Invention

[0007] Preferably, the rotation adjustment body includes a third motor, a fixed adjustment part, a second drive gear, a second synchronous rotating wheel, a support adjustment frame, a first rotating gear, a limit adjustment base, a first electric push rod, and a second synchronous belt. The first rotating gear is fixedly connected to the inner end of the limit adjustment base. The support adjustment frame is evenly slidably engaged with the limit adjustment base. The first electric push rod is symmetrically fixedly installed on the limit adjustment base, and its front end is fixedly connected to the inner end of the support adjustment frame. The third motor is fixedly installed on one of the support adjustment frames via the support frame. The second synchronous rotating wheel is rotatably engaged with the inner end of the support adjustment frame. The second drive gear is rotatably engaged with the outer end of the support adjustment frame, and the middle part of the second synchronous rotating wheel is fixedly connected to the middle part of the second drive gear. The second synchronous belt is rotatably disposed between the second synchronous rotating wheels. The drive end of the third motor is fixedly connected to the middle part of the outer end of one of the second synchronous rotating wheels via a reducer. The fixed adjustment part is disposed at the upper end of the support adjustment frame.

[0008] Preferably, the fixed adjustment part includes a limiting frame plate, an outward expansion support protrusion plate, a second rotating gear plate, a second electric push rod, and an adjustment mounting plate. The second rotating gear plate is fixedly connected to the outer end of the adjustment mounting plate, the limiting frame plate is fixedly connected to the middle of the inner end of the adjustment mounting plate, the second electric push rod is uniformly fixedly installed on the inner end of the adjustment mounting plate, the outward expansion support protrusion plate is movably disposed on the limiting frame plate, and the driving end of the second electric push rod is fixedly connected to the end of the outward expansion support protrusion plate.

[0011] Preferably, the axial height of the limiting frame plate is the same as the axial height of the rotating sandblasting retaining ring.

[0012] Preferably, a collection and discharge plate is fixedly installed at the bottom end of the support plate, and the collection and discharge plate is inclined at 45°.

[0013] A surface treatment process for iron cores includes the following steps:

[0014] S1. The iron core is clamped and placed in front of each limiting frame plate. Then, the first electric push rod pushes the support adjustment frame to slide along the limiting adjustment base so that the limiting frame plate can be inserted into the iron core. Then, the second electric push rod set on each adjustment mounting plate is activated. The second electric push rod controls the outward expansion support protrusions evenly distributed on the limiting frame plate to move outward. Thus, the internal support of the iron core can be limited by each outward expansion support protrusion, so that each iron core is firmly fixed.

[0015] S2. Then, the first electric push rod is activated, causing the support adjustment frame to move forward along with the adjustment mounting plate, the limit frame plate, and the fixed iron core into the interior of each rotating sandblasting ring. At this time, the solenoid valve is opened, allowing the delivery pipe to transport high-velocity gas and the internal abrasive to the interior of the rotating sandblasting ring, from which it is sprayed out from each sandblasting nozzle. This sandblasts the outer wall of the iron core, which is slowly moving inside the rotating sandblasting ring. During the sandblasting process, the second motor is activated, which drives a first synchronous rotating wheel and a drive gear to rotate in both directions. The first synchronous belt ensures that the evenly distributed drive gear and the first synchronous rotating wheel are synchronized. The system achieves forward and reverse rotation, which in turn drives the gear ring to swing in both directions via various drive gears. This allows the rotating sandblasting ring and the rotating retaining ring to rotate in both directions at the upper end of the support limit seat. This ensures that the sandblasting nozzles evenly distributed inside the rotating sandblasting ring can fully sandblast the outer wall of the iron core without any dead angles. Furthermore, the third motor is started, and through the set second synchronous rotating wheel and second synchronous belt, it can drive the second drive gear discs to rotate synchronously. The rotating second drive gear discs can drive the second rotating gear discs to rotate synchronously, thereby causing the limit frame plates and the outward expansion support protrusions to rotate, so that the fixed iron core can rotate and the outer wall of the iron core can be fully and comprehensively sandblasted.

[0016] S3. After sandblasting, the iron core is discharged from the inside of the rotating sandblasting retainer. The first motor is started to drive the first drive gear to rotate. The rotating first drive gear can drive the limit adjustment base to rotate through the first rotating gear, thereby indirectly controlling the iron core that is horizontally fixed at the front end of the limit frame to become vertical. Then, the first electric push rod is used to control the limit frame and the iron core fixed at the end to move downward and be inserted into the electroplating bath to achieve electroplating of chemical nickel on the outer wall of the iron core.

[0017] The beneficial effects of this invention are:

[0018] I. This invention can simultaneously fix multiple iron cores by setting a rotation adjustment body, and can perform thorough and rapid sandblasting treatment on the fixed iron cores by setting a sandblasting treatment body without dead angles by setting a sandblasting treatment body. The rotation adjustment body can control and adjust each fixed iron core, and the whole iron core can be electroplated with chemical nickel conveniently and quickly.

[0019] Second, this invention enables automatic and continuous electroplating after sandblasting of the iron core, making the processing continuous and greatly improving the efficiency of production. The sandblasting process is highly efficient. Attached Figure Description

[0032] The invention will be further described below with reference to the accompanying drawings. Example 1

[0033] like Figure 1 and Figure 2 As shown, a core surface treatment process of the present invention includes a first motor 1, a first drive gear 2, a fixed support base 3, a rotation adjustment body 6, and a sandblasting treatment body 7. The first drive gear 2 is rotatably mounted on the upper side of the fixed support base 3, and the first drive gears 2 are fixedly connected to each other by a fixing rod. The first motor 1 is fixedly mounted on the side of the fixed support base 3, and the drive end of the first motor 1 is fixedly connected to the middle of the outer side of one of the first drive gears 2 through a reducer. The rotation adjustment body 6 is set on the fixed support base 3, and the sandblasting treatment body 7 is set on the outer side of the rotation adjustment body 6. An auxiliary support plate 4 is fixedly installed on the upper side of the fixed support base 3, and support columns 5 are evenly fixedly installed on the auxiliary support plate 4 by bolts, which play a role in supporting the bottom of the limit adjustment base 29 and ensuring stability during use.

[0034] like Figure 3 and Figure 4As shown, the sandblasting body 7 includes a fixed support frame 8, a support plate 10, an iron core 11, a second motor 12, a support limit seat 13, a rotating retaining ring 14, a sandblasting nozzle 15, a delivery pipe 16, a solenoid valve 17, a rotating sandblasting retaining ring 18, a gear ring 19, a first synchronous belt 20, a drive gear 21, and a first synchronous rotating wheel 22. The fixed support frame 8 is fixedly connected to the support plate 10. The second motor 12 is fixedly installed in the middle of the upper end of the fixed support frame 8. The drive gear 21 rotates evenly and is engaged with the bottom end of the fixed support frame 8. The first synchronous rotating wheel... 22 is fixedly connected to the outer end of the drive gear 21. The first synchronous belt 20 is rotatably disposed between the first synchronous rotating pulleys 22. The front end of the second motor 12 is fixedly connected to the outer end of one of the first synchronous rotating pulleys 22 through a reducer. The support limiting seat 13 is fixed to the support fixing plate 10 by bolts. The rotating retaining ring 14 and the toothed ring 19 are fixed to the rotating sandblasting retaining ring 18, and the rotating retaining ring 14 is rotatably engaged inside the upper end of the support limiting seat 13. The solenoid valve 17 is fixedly connected to the outer end of the rotating sandblasting retaining ring 18. The conveying pipe 16 is fixedly connected to the solenoid valve. On 17, sandblasting nozzles 15 are evenly and fixedly installed inside the rotating sandblasting retainer 18. A gear ring 19 meshes with a drive gear 21. An iron core 11 is located inside the rotating sandblasting retainer 18. Opening the solenoid valve 17 allows the delivery pipe 16 to transport high-velocity gas and internal abrasive to the rotating sandblasting retainer 18, where it is ejected from each sandblasting nozzle 15. This sandblasts the outer wall of the iron core 11, which is inserted into the rotating sandblasting retainer 18 and moves slowly. During the sandblasting process, the second motor 12 is started, and the second motor 12... The first synchronous rotating wheel 22 and the drive gear 21 rotate in opposite directions. With the help of the first synchronous belt 20, the evenly distributed drive gear 21 and the first synchronous rotating wheel 22 can rotate in opposite directions synchronously. Thus, each drive gear 21 can drive the gear ring 19 to swing in opposite directions. Therefore, the rotating sandblasting retainer 18 and the rotating retainer 14 rotate in opposite directions at the upper end of the support limit seat 13. This allows the evenly distributed sandblasting nozzles 15 inside the rotating sandblasting retainer 18 to fully sandblast the outer wall of the iron core 11 without any dead corners.

[0035] like Figure 5 and Figure 6As shown, the rotation adjustment body 6 includes a third motor 23, a fixed adjustment part 24, a second drive gear 25, a second synchronous rotating wheel 26, a support adjustment frame 27, a first rotating gear 28, a limit adjustment base 29, a first electric push rod 30, and a second synchronous belt 31. The first rotating gear 28 is fixedly connected to the inner end of the limit adjustment base 29. The support adjustment frame 27 is evenly slidably engaged with the limit adjustment base 29. The first electric push rod 30 is symmetrically fixedly installed on the limit adjustment base 29, and its front end is fixedly connected to the inner end of the support adjustment frame 27. The third motor 23 is fixedly installed on a support adjustment frame 27 via a support frame. The second synchronous rotating wheel 26 is rotatably engaged with the inner end of the support adjustment frame 27. The second drive gear 25 is rotatably engaged with the inner end of the support adjustment frame 27. The outer end of the frame 27 and the middle part of the second synchronous rotating wheel 26 are fixedly connected to the middle part of the second drive gear 25. The second synchronous belt 31 is rotatably arranged between the second synchronous rotating wheels 26. The drive end of the third motor 23 is fixedly connected to the middle part of the outer end of one of the second synchronous rotating wheels 26 through a reducer. The fixed adjustment part 24 is arranged on the upper end of the support adjustment frame 27. When the third motor 23 is started, the second synchronous rotating wheel 26 and the second synchronous belt 31 can drive each second drive gear 25 to rotate synchronously. The rotating second drive gear 25 can drive each second rotating gear 34 to rotate synchronously, thereby causing each limiting frame plate 32 and the outward expansion support protrusion 33 to rotate, so that the fixed iron core 11 can rotate, and the outer wall of the iron core 11 can be fully and comprehensively sandblasted.

[0036] like Figure 7 and Figure 8 As shown, the fixed adjustment part 24 includes a limiting frame plate 32, an outward expansion support protrusion 33, a second rotating gear plate 34, a second electric push rod 35, and an adjustment mounting plate 36. The second rotating gear plate 34 is fixedly connected to the outer end of the adjustment mounting plate 36, the limiting frame plate 32 is fixedly connected to the middle of the inner end of the adjustment mounting plate 36, the second electric push rod 35 is evenly fixedly installed on the inner end of the adjustment mounting plate 36, the outward expansion support protrusion 33 is movably disposed on the limiting frame plate 32, and the driving end of the second electric push rod 35 is fixedly connected to the end of the outward expansion support protrusion 33. The outward expansion support protrusions 33 evenly distributed on the limiting frame plate 32 are controlled to move outward by the second electric push rod 35, so that the internal support of the iron core 11 can be limited by each outward expansion support protrusion 33, so that each iron core 11 is firmly fixed.

[0037] The second rotating gear 34 is rotatably engaged with the upper end of the support adjustment frame 27, and the second rotating gear 34 is meshed with the second drive gear 25. The inner end of the limit adjustment base 29 is rotatably engaged with the upper end of the fixed support base 3, and the first drive gear 2 is meshed with the first rotating gear 28.

[0038] The outward expansion support plate 33 is inserted into the interior of the iron core 11, which can support and fix the interior of the iron core 11.

[0039] The axis height of the limiting frame plate 32 is the same as the axis height of the rotating sandblasting retaining ring 18, so that the iron core 11 can be accurately inserted into the interior of the rotating sandblasting retaining ring 18 when it moves laterally.

[0040] The working principle of Embodiment 1 is as follows: The equipment is fixedly installed through the fixed support base 3 and the mounting holes provided on the fixed support base 3. The sandblasting body 7 can be fixedly installed as a whole through the support fixing plate 10 and the mounting holes provided on the support fixing plate 10. After the fixed installation, the iron core 11 is clamped and placed in front of each limiting frame plate 32. Then, the first electric push rod 30 pushes the support adjustment frame 27 to slide along the limiting adjustment base 29, so that the limiting frame plate 32 can be inserted into the iron core 11. Then, the second electric push rod 35 provided on each adjusting mounting plate 36 is activated, and the second electric push rod 35 ... The electric push rod 35 controls the outward movement of the evenly distributed outward support protrusions 33 on the limiting frame plate 32, thereby limiting the internal support of the iron core 11 through each outward support protrusion 33, so that each iron core 11 is firmly fixed. Then, the first electric push rod 30 is activated to cause the support adjustment frame 27 to drive the adjustment mounting plate 36, the limiting frame plate 32, and the fixed iron core 11 to continue to move forward into the interior of each rotating sandblasting retainer 18. At this time, the solenoid valve 17 is opened so that the delivery pipe 16 can deliver high-velocity gas and the internal abrasive sand into the interior of the rotating sandblasting retainer 18 for each abrasive sandblasting ring. The sandblasting nozzle 15 sprays sand onto the outer wall of the iron core 11, which is slowly moving inside the rotating sandblasting retainer 18. During the sandblasting process, the second motor 12 is started, which drives a first synchronous rotating wheel 22 and a drive gear 21 to rotate in both directions. With the help of the first synchronous belt 20, the evenly distributed drive gears 21 and the first synchronous rotating wheel 22 can rotate synchronously in both directions. Thus, each drive gear 21 can drive the gear ring 19 to swing in both directions, thereby causing the rotating sandblasting retainer 18 and the rotating retainer 14 to move in both directions on the support limit seat 13. The rotation of the end in both directions allows the sandblasting nozzles 15, which are evenly distributed inside the rotating sandblasting retainer 18, to fully sandblast the outer wall of the iron core 11 without any dead angles. The third motor 23 is started, and through the set second synchronous rotating wheel 26 and the second synchronous belt 31, it can drive the second drive gear 25 to rotate synchronously. The rotating second drive gear 25 can drive the second rotating gear 34 to rotate synchronously, thereby causing the limiting frame plate 32 and the outward expansion support protrusion 33 to rotate, so that the fixed iron core 11 can rotate, and the outer wall of the iron core 11 can be fully and comprehensively sandblasted.

[0041] After sandblasting, the iron core 11 is discharged from the inside of the rotating sandblasting retainer 18. The first motor 1 is started to drive the first drive gear 2 to rotate. The rotating first drive gear 2 can drive the limit adjustment base 29 to rotate through the first rotating gear 28, thereby indirectly controlling the iron core 11, which is horizontally fixed at the front end of the limit frame plate 32, to become vertical. Then, the first electric push rod 30 is used to control the limit frame plate 32 and the iron core 11 fixed at the end to move downward and be inserted into the electroplating bath to achieve electroplating of chemical nickel on the outer wall of the iron core 11.

[0042] A surface treatment process for iron cores includes the following steps:

[0043] S1. The iron core 11 is clamped and placed in front of each limiting frame plate 32. Then, the first electric push rod 30 pushes the support adjustment frame 27 to slide along the limiting adjustment base 29 so that the limiting frame plate 32 can be inserted into the iron core 11. Then, the second electric push rod 35 set on each adjustment mounting plate 36 is activated. The second electric push rod 35 controls the outward expansion support protrusions 33 evenly distributed on the limiting frame plate 32 to move outward. Thus, the internal support of the iron core 11 can be limited by each outward expansion support protrusion 33, so that each iron core 11 is firmly fixed.

[0044] S2. Then, the first electric push rod 30 is activated, causing the support adjustment frame 27 to move the adjustment mounting plate 36, the limit frame plate 32, and the fixed iron core 11 forward into the interior of each rotating sandblasting retainer 18. At this time, the solenoid valve 17 is opened, allowing the delivery pipe 16 to deliver high-velocity gas and the internal abrasive to the interior of the rotating sandblasting retainer 18, from which it is sprayed out from each sandblasting nozzle 15. This sandblasts the outer wall of the iron core 11, which is slowly moving inside the rotating sandblasting retainer 18. During the sandblasting process, the second motor 12 is activated, which drives a first synchronous rotating wheel 22 and a drive gear 21 to rotate in both directions. With the help of the first synchronous belt 20, the evenly distributed drive gear 21 and the first synchronous rotating wheel 22 can be synchronized. The rotation of the rotating ring 19 is achieved by the forward and reverse rotation of the rotating sandblasting ring 18 and the rotating ring 14 at the upper end of the support limit seat 13. This allows the sandblasting nozzles 15 evenly distributed inside the rotating sandblasting ring 18 to fully sandblast the outer wall of the iron core 11 without any dead angles. The third motor 23 is started, and the second synchronous rotating wheel 26 and the second synchronous belt 31 drive the second driving gear 25 to rotate synchronously. The rotating second driving gear 25 drives the second rotating gear 34 to rotate synchronously, thereby causing the limit frame plate 32 and the outward expansion support protrusion 33 to rotate, so that the fixed iron core 11 can rotate and the outer wall of the iron core 11 can be fully and comprehensively sandblasted.

[0045] S3. After the sandblasting is completed, the iron core 11 is discharged from the inside of the rotating sandblasting retainer 18. The first motor 1 is started to drive the first drive gear 2 to rotate. The rotating first drive gear 2 can drive the limit adjustment base 29 to rotate through the first rotating gear 28, thereby indirectly controlling the iron core 11, which is horizontally fixed at the front end of the limit frame plate 32, to become vertical. Then, the first electric push rod 30 is used to control the limit frame plate 32 and the iron core 11 fixed at the end to move downward and be inserted into the electroplating bath to achieve electroplating of chemical nickel on the outer wall of the iron core 11. Example 2

[0046] Based on Example 1, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a collection and discharge plate 9 is fixedly installed at the bottom of the support plate 10, and the collection and discharge plate 9 is inclined at 45°.

[0047] In implementing this embodiment, the sprayed abrasive can be collected and slid off by the collection and discharge plate 9, making it easy to handle large abrasive particles and making the equipment easy to use.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

7. A core surface treatment process, employing the core surface treatment apparatus described in claim 6, characterized in that, It includes the following steps: S1. The iron core (11) is clamped and placed in front of each limiting frame plate (32). Then, the first electric push rod (30) pushes the support adjustment frame (27) to slide along the limiting adjustment base (29) so that the limiting frame plate (32) can be inserted into the iron core (11). Then, the second electric push rod (35) set on each adjustment mounting plate (36) is activated. The second electric push rod (35) controls the outward expansion support protrusions (33) evenly distributed on the limiting frame plate (32) to move outward. Thus, the internal support of the iron core (11) can be limited by each outward expansion support protrusion (33), so that each iron core (11) is firmly fixed. S2. Then, the first electric push rod (30) is started again, causing the support adjustment frame (27) to drive the adjustment mounting plate (36), the limit frame plate (32), and the fixed iron core (11) to continue moving forward into the interior of each rotating sandblasting ring (18). At this time, the solenoid valve (17) is opened, so that the delivery pipe (16) can deliver high-flow-rate gas and the internal abrasive to the interior of the rotating sandblasting ring (18) and spray it out from each sandblasting nozzle (15), thereby sandblasting the outer wall of the iron core (11) that is slowly moving into the interior of the rotating sandblasting ring (18). During the sandblasting process, the second motor (12) is started. The second motor (12) can drive a first synchronous rotating wheel (22) and a drive gear (21) to rotate in opposite directions. With the help of the first synchronous belt (20), the evenly distributed drive gear (21) and the first synchronous rotating wheel (22) can rotate in the same direction. The steps achieve forward and reverse rotation, thereby driving the gear ring (19) to swing forward and reverse through each drive gear (21), thus causing the rotating sandblasting ring (18) and rotating ring (14) to rotate forward and reverse at the upper end of the support limit seat (13), so that each sandblasting nozzle (15) evenly distributed inside the rotating sandblasting ring (18) can fully sandblast the outer wall of the iron core (11) without dead corners, and start the third motor (23), through the set second synchronous rotating wheel (26) and second synchronous belt (31) to drive each second drive gear (25) to rotate synchronously, and the rotating second drive gear (25) can drive each second rotating gear (34) to rotate synchronously, thereby causing each limit frame plate (32) and the outward expansion support protrusion (33) to rotate, so that the fixed iron core (11) can rotate, and the outer wall of the iron core (11) can be fully and comprehensively sandblasted; S3. After the sandblasting is completed, the iron core (11) is discharged from the inside of the rotating sandblasting retainer (18). The first motor (1) is started to drive the first drive gear (2) to rotate. The rotating first drive gear (2) can drive the limit adjustment base (29) to rotate through the first rotating gear (28), thereby indirectly controlling the iron core (11) that is horizontally fixed at the front end of the limit frame plate (32) to become vertical. Then, the first electric push rod (30) is used to control the iron core (11) that is fixed at the front end of the limit frame plate (32) to move downward and insert into the electroplating bath to achieve electroplating of the outer wall of the iron core (11) with chemical nickel.
