Description

Technical Field

[0001] The utility model relates to the technical field of motor production equipment, in particular to an automatic turning device for motor assembly. Background Art

[0002] An electric motor, commonly known as a motor, refers to an electromagnetic device that realizes electrical energy conversion or transmission based on the law of electromagnetic induction. The main function of the motor is to generate driving torque. As the power of electrical appliances or various machines, the motor is generally composed of a stator, a rotor and other accessories. The stator is the stationary part of the motor or generator. The main function of the stator is to generate a rotating magnetic field, and the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current. At present, the motor needs to be assembled before use. In the existing motor assembly process, the motor is assembled in a horizontal state when the rotor and stator are installed. However, when assembling the oil seal, it is generally manually flipped to a vertical state and then the oil seal is assembled.

[0003] There are also some devices in the prior art that can flip the motor. For example, the authorization announcement No. CN212258717U discloses an automatic flipping device for motor assembly. Although this device can flip the motor, it requires precise coordination between the motor and the clamping mechanism, and the motor is clamped by slowly feeding the electric push rod. This not only affects the assembly efficiency, but also when there is a slight error between the motor and the equipment, it is easy to cause damage to the motor, and there is even a risk of injuring employees. Therefore, an automatic flipping device for motor assembly is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide an automatic turning device for motor assembly, which has the advantages of high electrode fixing efficiency and high safety factor, and solves the problems in the prior art that the motor reversal efficiency is too low and the reversal equipment is easy to cause motor damage or injure employees.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an automatic flipping device for motor assembly, comprising legs, a support platform and a driving motor, wherein an electromagnet is arranged in the support platform, and an anti-slip mechanism is arranged on the side of the support platform;

[0006] The left and right ends of the support platform are provided with a first rotating shaft, the support platform is rotatably connected to the support leg through the first rotating shaft, the drive motor is connected to the first rotating shaft through a reducer transmission, the anti-slip mechanism includes a protective bracket, a slide rail and a handle, the slide rail is fixedly installed at the lower end of the support platform, the protective bracket is inserted into the slide rail and slidably connected to the support platform, and the handle is installed on the protective bracket.

[0007] As a preferred automatic flipping device for motor assembly of the utility model, the protective bracket is a "U"-shaped carbon steel frame, and the protective bracket is inserted into the slide rail from the end of the support platform away from the support leg and is slidably connected to the support platform.

[0008] As a preferred automatic flipping device for motor assembly of the utility model, a second rotating shaft is provided on the side of the protective bracket, a torsion spring is provided on the first rotating shaft, the handle and the protective bracket are rotatably connected through the cooperation of the second rotating shaft and the torsion spring, a pawl is provided on the handle, a ratchet bar is provided on the lower end surface of the support platform, and the handle and the support platform are meshed and connected through the pawl and the ratchet bar.

[0009] As a preferred embodiment of the automatic turning device for motor assembly of the utility model, a longitudinal grip is provided at the lower end of the handle.

[0010] As a preferred embodiment of the automatic flipping device for motor assembly of the utility model, the support platform is provided with a rotatably connected sliding roller, and the central axis of the sliding rail is perpendicular to the central axis of the first rotating shaft.

[0011] As a preferred embodiment of the automatic flipping device for motor assembly of the utility model, the inner end surface of the support leg is provided with a foot switch electrically connected to the motor and the electromagnet.

[0012] As a preferred embodiment of the automatic turning device for motor assembly of the utility model, the top side end surface of the protective bracket is provided with a threaded adjustment bolt.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model realizes automatic flipping of the motor by driving the motor, reducer and other components, without manual operation, which greatly reduces the labor intensity of workers, and instantly fixes the motor by electromagnet adsorption, which greatly improves work efficiency. It is especially suitable for large-scale motor assembly operations. The device not only relies on electromagnets to adsorb the motor, but also specially designs an anti-slip mechanism to form a double insurance. Even if the electromagnet fails or the suction force is insufficient, it can still effectively prevent the motor from falling. This may provide higher safety redundancy than devices that rely on a single adsorption method.

[0015] 2. The utility model uses the handle, pawl and ratchet bar to make the installation and removal of the protective bracket simple and quick, which may be better than devices that require complicated steps or tools to fix or release the motor. At the same time, the design of the longitudinal handle enables workers to operate the protective bracket easily and quickly. The setting of the sliding roller helps to reduce the friction between the motor and the support table, which may make the motor flip more smooth and easier to integrate with the conveyor belt system, thereby improving the smoothness of the overall production line.

[0016] 3. The utility model provides an adjustment bolt on the side of the protective bracket so that the device can adapt to the assembly requirements of motors of different sizes, especially the compatibility with non-standard sizes or small motors may be better than the flip device designed with fixed specifications.

DETAILED DESCRIPTION

[0022] See also Figure 1-Figure 4 , an automatic flipping device for motor assembly, comprising a support leg 1, a support platform 2 and a driving motor 3, an electromagnet 203 is arranged in the support platform 2, and an anti-slip mechanism 4 is arranged on the side of the support platform 2;

[0023] A first rotating shaft 201 is provided at the left and right ends of the support platform 2. The support platform 2 is rotatably connected to the support leg 1 through the first rotating shaft 201. The driving motor 3 is connected to the first rotating shaft 201 through a reducer transmission. The anti-slip mechanism 4 includes a protective bracket 410, a slide rail 430 and a handle 420. The slide rail 430 is fixedly installed at the lower end of the support platform 2. The protective bracket 410 is inserted into the slide rail 430 and is slidably connected to the support platform 2. The handle 420 is installed on the protective bracket 410.

[0024] Furthermore, the protective bracket 410 is a "U"-shaped carbon steel frame, and the protective bracket 410 is inserted into the slide rail 430 from the end of the support platform 2 away from the support leg 1 and is slidably connected to the support platform 2.

[0025] The protective bracket 410 can clamp the mounting base of the motor to be flipped, thereby preventing the electromagnet 203 from malfunctioning or insufficient suction of the electromagnet from causing the motor to fall and injure employees or cause damage to the motor.

[0026] Furthermore, a second rotating shaft 411 is provided on the side of the protective bracket 410, a torsion spring 413 is provided on the first rotating shaft 201, the handle 420 and the protective bracket 410 are rotatably connected through the cooperation of the second rotating shaft 411 and the torsion spring 413, a pawl 421 is provided on the handle 420, a ratchet bar 204 is provided on the lower end surface of the support platform 2, and the handle 420 and the support platform 2 are meshed and connected through the pawl 421 and the ratchet bar 204.

[0027] The pawl 421 is automatically clamped on the ratchet bar 204 under the action of the torsion spring 413, so that the protection bracket 410 can only slide in one direction toward the end of the leg 1, thereby facilitating the rapid installation of the protection bracket 410 and effectively preventing the motor from falling.

[0028] Furthermore, a longitudinal grip 422 is provided at the lower end of the handle 420 .

[0029] The protective bracket 410 can be pulled conveniently by the longitudinal grip 422 , and during the pulling process, the longitudinal grip 422 will drive the handle 420 to flip, so that the pawl 421 and the ratchet bar 204 are quickly separated, so that the protective bracket 410 can be quickly pulled out conveniently.

[0030] Furthermore, a rotatably connected sliding roller 202 is provided on the support platform 2 , and the central axis of the sliding rail 430 is perpendicular to the central axis of the first rotating shaft 201 .

[0031] The friction between the motor to be flipped and the support platform 2 is reduced by the sliding roller 202, thereby facilitating the cooperation with the conveyor belt, thereby facilitating the loading and unloading of the motor.

[0032] Furthermore, a foot switch 101 electrically connected to the motor and the electromagnet 203 is provided on the inner end surface of the leg 1 .

[0033] The operation of the equipment can be conveniently controlled by the foot switch 101, and the foot switch 101 is arranged at the lower end of the mounting table near the side of the leg 1, forcing the employee to operate near the side of the leg 1. When the equipment is running, if the motor falls, it will not hurt the user.

[0034] Furthermore, a threaded adjustment bolt 412 is disposed on the top side end surface of the protection bracket 410 .

[0035] When the gap between the mounting base of the motor to be flipped and the protective bracket 410 is too large, the adjustment bolt 412 can be rotated to compensate for the gap to accommodate some motors with too small or non-standard sizes.

[0036] When the flipping device is in use, the motor to be flipped is pushed onto the support platform 2, ensuring that the motor mounting base is aligned with the protective bracket 410 of the anti-slip mechanism 4, and the protective bracket 410 is moved toward the end of the motor to be flipped so that it presses the motor mounting base. The operator stands on the side of the support leg 1, steps on the foot switch 101 to start the equipment, and the electromagnet 203 starts working to adsorb the motor mounting base. The drive motor 3 drives the support platform 2 to rotate counterclockwise ninety degrees through the reducer, thereby realizing automatic flipping of the motor. After flipping into place, the drive motor 3 stops working, the electromagnet 203 remains adsorbed, and the motor is assembled. After the assembly is completed, the foot switch 101 is stepped on again to reset the support platform 2, the electromagnet 203 is powered off, the adsorption is released, and the longitudinal handle 422 is pulled outward to release the protective bracket 410.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
