Description
Technical Field
[0001] The utility model relates to the technical field of painting equipment, in particular to a semi-automatic rotating device for spraying screw rotors. Background Technique
[0002] A rotor is a moving part in the electromagnetic system of an electric motor, a generator, and an alternator. Generally, a rotor consists of a rotor core and a rotating shaft. Whether it is a cast aluminum rotor or a wound rotor, its surface needs to be turned, and grinding may be carried out when necessary. To prevent rust on the surface of the rotor core after machining, a method of surface painting is adopted for rust prevention. Therefore, different motor manufacturers will use different colors to paint the surface of the rotor, which not only provides protection but also enhances the industrial beauty of the rotor.
[0003] When spraying a rotor, generally, a support is set on a platform, the rotor is placed on the support, one hand evenly turns the rotor, and the other hand holds a spray gun to spray paint. Only with the high coordination of both hands can the spraying work be completed well.
[0004] However, it is difficult to maintain the coordination of both sides when operating with both hands at the same time. The operation requirements are high, and it is difficult to control the speed of the rotor during rotation, resulting in uneven spraying of the rotor.

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0029] The following will further elaborate on this application Figure 1-6 in further detail.
[0030] A semi-automatic rotating device for spraying a screw rotor includes a rotor 2, a platform 4, and a support 3 placed on the platform 4. The support 3 includes a base 14 and a first support seat 32. The first support seat 32 is arranged above the base 14. A bearing roller 31 is rotatably arranged on the first support seat 32. A rotating device 1 is arranged on one side of the base 14 away from the support 3. The rotating device 1 includes a bracket, a jacket 5, a motor 11, and a rotating shaft 12. The motor 11 is fixedly arranged on the bracket. One end of the rotating shaft 12 is coaxially fixed to the rotating shaft of the motor 11, and the other end of the rotating shaft 12 is coaxially fixedly connected to the jacket 5. The jacket 5 is detachably connected to the rotor 2. When the rotating device 1 rotates, the jacket 5 is fixedly connected to the rotor 2, and the rotor 2 is horizontally placed on the first support seat 32.
[0031] During use, first place one end of the rotor 2 on the first support seat 32, and then connect the other end of the rotor 2 to the jacket 5. At this time, the rotor 2 is horizontally fixed on the device. Then start the motor 11. The rotating shaft on the motor 11 drives the jacket 5 to rotate at a constant speed. One end of the rotor 2 rotates together with the jacket 5, and the other end of the rotor 2 is placed on the first support seat of the rotor 2 and rotates together with the bearing roller 31 on the first support seat 32. After the rotor 2 rotates, the rotor 2 can be sprayed. The rotational movement of the motor 11 is used to replace the rotation of the human hand. The rotation direction, rotation speed, and torque of the motor 11 can all be grasped in real time through the control part, avoiding the problem of uneven spraying of the rotor 2.
[0032] A chute 34 is provided on the base 14, a slider 38 is provided in the chute 34, the first support base 32 is fixedly connected to the slider 38, a nut seat 36 is provided below the chute 34, a screw rod 35 is threadedly connected to the nut seat 36, and a screw rod fixing seat 37 is rotatably connected to the screw rod 35. When facing rotors 2 of different lengths, the distance between the support base and the clamping sleeve 5 can be adjusted first. When encountering a longer rotor 2, the screw rod 35 is rotated clockwise first, so that the nut seat 36 on the screw rod 35 starts to move, and the nut seat 36 drives the slider 38 to start sliding in the chute 34. At this time, the first support base 32 moves away from the clamping sleeve 5, and the distance between the first support base 32 and the clamping sleeve 5 is widened, and the rotor 2 can be horizontally placed between the two and rotated. On the contrary, if a shorter rotor 2 is encountered, only the screw rod 35 needs to be rotated counterclockwise until the support base moves to a suitable distance, making the use of the rotating device more inclusive.
[0033] On one side of the base 14 close to the clamping sleeve 5, a second support is fixedly provided, which can further support the rotor 2. The two ends of the rotor 2 are respectively placed on the first support base 32 and the second support base 33, reducing the risk of the rotor 2 slipping and enhancing the stability of the device; two bearing rollers 31 are rotatably provided on both the first support base 32 and the second support. When the rotor 2 is placed on the first support base 32 and the second support, the shaft of the rotor 2 is located between the two bearing rollers 31. When the rotor 2 rotates, the two bearing rollers 31 will rotate together. On the one hand, it can prevent the rotor 2 from easily detaching from the support base, and on the other hand, it can make the rotation of the rotor 2 smoother and unobstructed; a universal joint 13 is fixedly provided on the rotating shaft 12. When encountering rotors 2 of different sizes, the center height of the rotor 2 is different, and the universal joint 13 can achieve power transmission at variable angles, increasing the applicability of the rotating device.
[0034] The clamping sleeve 5 includes a clamping block 52 and a mounting block 51. A threaded hole 54 is provided in the mounting block 51, and a connecting rod 53 is threadedly connected to the threaded hole 54. The clamping block 52 is divided into a fixed block 522 and a sliding block 521. The fixed block 522 is fixed on the mounting block 51, and the sliding block 521 is rotatably connected to the connecting rod 53. When installing the rotor 2, first insert one end of the rotor 2 into the mounting block 51, and the bottom of the shaft enters between the fixed block 522 and the sliding block 521. Then rotate the connecting rod 53 downward, so that the connecting rod 53 drives the sliding block 521 to move downward until the sliding block 521 presses the shaft against the fixed block 522, connecting the rotor 2 to the clamping sleeve 5.
[0035] The implementation principle of this embodiment is as follows: First, place the rotor 2 on the first support base 32 and the second support base 33. Insert one end of the rotor 2 into the mounting block 51. The bottom of the shaft enters between the fixed block 522 and the sliding block 521. Then rotate the connecting rod 53 downward, so that the connecting rod 53 drives the sliding block 521 to move downward until the sliding block 521 presses the shaft against the fixed block 522, connecting the rotor 2 to the jacket 5.
[0036] At this time, the rotor 2 is horizontally fixed on the device. Start the motor 11. The rotating shaft on the motor 11 drives the jacket 5 to rotate at a constant speed. One end of the rotor 2 rotates together with the jacket 5. The other end of the rotor 2 rotates together with the bearing roller 31 on the first support base 32 placed on the support of the rotor 2. The shaft of the rotor 2 is located between the two bearing rollers 31. When the rotor 2 rotates, the two bearing rollers 31 will rotate together. After the rotor 2 rotates, the rotor 2 can be sprayed. Use the rotational movement of the motor 11 to replace the rotation of the human hand. The rotation direction, rotation speed, and torque of the motor 11 can all be grasped in real time through the control part, avoiding the problem of uneven spraying of the rotor 2.
