Description

Technical Field

[0001] This utility model relates to the field of rotor production technology, specifically to an annular air-inlet drying device for a cast aluminum rotor production line. Background Technology

[0002] Cast aluminum rotors are a common type of rotor in electric motors. They typically consist of a core made of stacked silicon steel sheets, aluminum conductor bars cast into the core slots, and aluminum end rings at both ends. Their overall shape resembles a squirrel cage, hence the name "squirrel cage rotor." When three-phase alternating current is applied to the motor stator windings, a rotating magnetic field is generated. This rotating magnetic field has a relative cutting motion with the rotor conductors. According to the principle of electromagnetic induction, the rotor conductors generate an induced electromotive force and an induced current. The current-carrying rotor conductors experience an electromagnetic force in the magnetic field, forming an electromagnetic torque that drives the rotor to rotate. Aluminum is relatively inexpensive, and the casting process is relatively simple and efficient, resulting in low manufacturing costs for cast aluminum rotors. They are widely used in motors in various industrial fields, such as fans, pumps, compressors, and machine tools, where cost and reliability requirements are high, and cast aluminum rotors meet these needs.

[0003] Drying is a crucial step in the production of cast aluminum rotors. Drying effectively removes moisture, preventing problems such as short circuits and corrosion caused by moisture during subsequent use, and improving the rotor's insulation performance and service life. Existing rotor production drying equipment typically uses a frame to support the raw materials, but fixing the angle of material handling is inconvenient, and the poor uniformity of drying reduces its practicality.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a ring-shaped air-inlet drying device for an aluminum casting rotor production line, comprising a protective shell, a lower support frame fixedly connected to its lower surface, an upper cover plate provided at the upper end of the protective shell, an exhaust fan installed on the lower side surface of the protective shell, an air inlet pipe installed on the front surface of the protective shell, an annular air groove formed in the inner wall of the cavity of the protective shell, an air outlet mounting frame fixedly installed on the inner wall of the cavity of the protective shell, drying air outlets evenly formed on the inner side surface of the air outlet mounting frame, a support base fixedly connected to the bottom surface of the cavity of the protective shell, a supporting disc provided at the upper end of the support base, a positioning column fixedly connected to the upper surface of the supporting disc, a lower limit clamp fixedly connected between two positioning columns, and a positioning mechanism provided between the positioning columns and the supporting disc, which drives the upper limit clamp and the locking block to slide through the positioning sliding column installed in the slot, thereby limiting the raw material.

[0006] Preferably, the protective shell is cylindrical, the air inlet duct corresponds to the tangent of the protective shell, and the air inlet duct is connected to the annular air groove.

[0007] By adopting the above technical solution, the cylindrical design of the protective shell facilitates the direct flow of air into the annular air groove through the air inlet duct.

[0010] Preferably, the support base and the supporting disc are rotatably connected, the upper surface of the supporting disc is provided with a groove, and the lower limit clamp surface is provided with an arc-shaped groove.

[0011] By adopting the above technical solution, the support base is rotatably connected to the support disc, which facilitates the rotation of the support disc for the assembly and disassembly of raw materials.

[0012] Preferably, the positioning mechanism includes an installation slot, which is formed between the supporting disc and the positioning column. The inner wall of the installation slot is provided with a positioning slide column. The upper side surfaces of the two positioning slide columns are fixedly connected with upper limit clamps, and the lower end of the positioning slide column is fixedly connected with a locking block.

[0013] Using the above technical solution, the groove is installed to facilitate the movement of the positioning slide column, and the upper limit clamp is installed on the positioning slide column.

[0014] Preferably, the mounting slot and the positioning slide post are slidably connected, and a spring is connected between the upper end of the positioning slide post and the mounting slot.

[0015] By adopting the above technical solution, the sliding of the positioning slide column causes the upper limit clamp to correspond with the lower limit clamp, thereby limiting the material.

[0016] Preferably, the upper limit clamp surface is provided with an arc-shaped groove, and the groove of the upper limit clamp corresponds to the groove of the lower limit clamp, and the locking block and the supporting disc form a locking connection.

[0017] Using the above technical solution, the movement of the positioning slide column causes the positioning slide column to drive the locking block to engage and fix with the supporting disc.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the cast aluminum rotor production line uses an annular air-inlet drying device.

[0019] 1. The device is equipped with an annular air groove and an air outlet mounting bracket. When the device is working, hot air enters the annular air groove along the circumferential tangent of the protective shell through the air inlet pipe. The hot air is then evenly distributed around the circumference of the air outlet mounting bracket and then sprayed out evenly through the circumferentially distributed drying air outlets to dry the raw materials. This allows the raw materials to fully contact the hot air and improves the drying effect of the device.

[0020] 2. The device is equipped with a lower limit clamp and an upper limit clamp. When the device is working, the lower limit clamp can easily support the raw material. Then, the positioning slide and the upper limit clamp are lowered by the spring, so that the upper limit clamp can limit the raw material through the groove, thereby improving the overall stability of the raw material when the device is working.

[0021] 3. The device is equipped with a locking block and a supporting disc. When the device is working, the rotation of the support base and the supporting disc facilitates the picking and placing of raw materials. When fixing the raw materials, the descent of the positioning slide will cause the locking block to slide and engage with the groove of the supporting disc, which will help to fix the support base and the supporting disc, further improving stability and increasing the ease of use of the device.

Detailed Implementation

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figure 1-6 This utility model provides a technical solution: a ring-shaped air-inlet drying device for an aluminum casting rotor production line, comprising a protective shell 1, a lower support frame 2, an upper cover plate 3, an exhaust fan 4, an air inlet pipe 5, an annular air groove 6, an air outlet mounting frame 7, a drying air outlet 8, a support base 9, a supporting disc 10, a positioning column 11, a lower limit clamp 12, a mounting slot 13, a positioning slide column 14, an upper limit clamp 15, and a locking block 16. The lower support frame 2 is fixedly connected to the lower surface of the protective shell 1, and an upper cover plate is provided at the upper end of the protective shell 1. The lower side surface of the cover plate 3 and the protective shell 1 is equipped with an exhaust fan 4, and the front surface of the protective shell 1 is equipped with an air inlet duct 5. The protective shell 1 is cylindrical in design, and the air inlet duct 5 corresponds to the tangent of the protective shell 1. The air inlet duct 5 is connected to the annular air groove 6. When using this device, the raw material is first placed on the surface of the lower support frame 2. The spring on the top surface of the slotted 13 pushes the positioning slide column 14 down, which facilitates the positioning slide column 14 to drive the upper limit clamp 15 to limit the raw material, thereby improving the stability of the raw material.

[0031] The inner wall of the cavity of the protective shell 1 is provided with an annular air groove 6. An air outlet mounting bracket 7 is fixedly installed on the inner wall of the cavity of the protective shell 1. Drying air outlets 8 are evenly provided on the inner surface of the air outlet mounting bracket 7. The height of the annular air groove 6 corresponds to the height of the air outlet mounting bracket 7. The drying air outlets 8 are arranged in a circumferential array about the air outlet mounting bracket 7, and one end of the drying air outlet 8 is connected to the annular air groove 6. The support base 9 and the supporting disc 10 are rotatably connected. The upper surface of the supporting disc 10 is provided with a groove, and the surface of the lower limit clamp 12 is provided with an arc-shaped groove. When the positioning slide column 14 slides down, it drives the locking block 16 to descend, so that the locking block 16 can engage with the supporting disc 10, thereby fixing the supporting disc 10 and the support base 9. When disassembling the raw materials, the positioning slide column 14 drives the locking block 16 to rise, which makes it easier to rotate the supporting disc 10 and disassemble the raw materials, thus increasing the practicality of the device.

[0032] A support base 9 is fixedly connected to the bottom surface of the cavity of the protective shell 1. A support disc 10 is provided on the upper end of the support base 9. A positioning column 11 is fixedly connected to the upper surface of the support disc 10. A lower limit clamp 12 is fixedly connected between the two positioning columns 11. The positioning mechanism includes an installation slot 13, which is opened between the support disc 10 and the positioning column 11. A positioning slide column 14 is provided on the inner wall of the installation slot 13. An upper limit clamp 15 is fixedly connected to the upper side surface of the two positioning slide columns 14. A locking block 16 is fixedly connected to the lower end of the positioning slide column 14. During operation, hot air is introduced into the tangent of the annular air groove 6 through the air inlet pipe 5, so that the annular air groove 6 can disperse the hot air in a circular manner.

[0033] A positioning mechanism is provided between the positioning column 11 and the supporting disc 10. The positioning mechanism drives the upper limit clamp 15 and the locking block 16 to slide through the positioning slide column 14 in the mounting slot 13, thereby limiting the material. The mounting slot 13 and the positioning slide column 14 form a sliding connection. A spring is connected between the upper end of the positioning slide column 14 and the mounting slot 13. The surface of the upper limit clamp 15 is provided with an arc-shaped groove, and the groove of the upper limit clamp 15 corresponds to the groove of the lower limit clamp 12. The locking block 16 and the supporting disc 10 form a locking connection. The annular air groove 6 discharges air through multiple drying air outlets 8 in a circumferential array, which facilitates the air outlet mounting frame 7 to guide the hot air to the material, thereby improving the efficiency and uniformity of drying the material.

[0034] Working principle: When using the annular air-inlet drying device for the cast aluminum rotor production line, the raw material is first placed on the surface of the lower limit clamp 12 between the positioning columns 11. The positioning slide column 14 and the upper limit clamp 15 are pushed down by the inner wall spring of the slotted 13 to facilitate the limiting of the raw material. At the same time, the positioning slide column 14 drives the locking block 16 to slide down and engage the supporting disc 10 to prevent the support base 9 and the supporting disc 10 from rotating. Hot air is introduced into the annular air groove 6 through the air inlet pipe 5, and then the hot air is discharged from the drying air outlet 8 after the air outlet mounting bracket 7, which facilitates the blowing and drying of the raw material. Finally, the internal cavity is discharged through the exhaust fan 4, which increases the overall practicality.
