Description

Technical Field

[0001] The utility model relates to the technical field of DC motor assembly, in particular to an assembly device for a DC motor. Background Art

[0002] A DC motor is a type of motor. A motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. Its main function is to generate driving torque. As a power source for electrical appliances or various machines, it is a common power center in people's lives. For example, the motor in a toy car, a household range hood, and a washing machine are all driven by motors. In the prior art, the motor coil is installed in the motor housing. During the production process, it is often installed manually by workers. In order to install accurately, the gap between the motor coil and the motor housing is small, which requires workers to use greater force for assembly.

[0003] For this purpose, there are some motor assembly devices in the prior art for assembling motors, such as the Chinese invention patent with publication number CN111431358B, which discloses a motor coil assembly machine. However, in actual use, we found that the above-mentioned device needs to use two sets of limiting structures when in use, which increases the actual cost. In addition, for the coil, the use of external support is likely to interfere with the subsequent operation of squeezing the coil into the motor housing, so how to solve this problem needs to be considered. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an assembly device for a DC motor. During use, the assembly device uses a limit groove part to replace the existing left and right limit of the motor housing part, which can reduce the actual cost of the entire device. In addition, the operation of internal support is adopted to avoid the interference of the support part on the installation.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A DC motor assembly device comprises a base, the upper end of the base is fixedly connected to a vertical plate, the upper end of the vertical plate is fixedly connected to a horizontal plate; a pressurizing mechanism, the pressurizing mechanism comprises a first hydraulic telescopic rod fixedly connected to the lower end of the horizontal plate, the telescopic end of the first hydraulic telescopic rod is fixedly connected to an extrusion disk; a guide mechanism, the guide mechanism cooperates with the pressurizing mechanism; and an internal support mechanism, the internal support mechanism is located at the lower end of the extrusion disk.

[0007] Preferably, a limiting groove is provided at the upper end of the base, and the limiting groove cooperates with the housing of the DC motor.

[0008] Preferably, the guide mechanism includes two guide rods symmetrically fixedly connected to the upper end of the extrusion disk, and the upper end of the cross plate is penetrated by two guide openings. Both of the two guide rods penetrate the corresponding guide openings and are slidably connected to the corresponding guide openings.

[0009] Preferably, the first hydraulic telescopic rod is a multi-section telescopic rod.

[0010] Preferably, the internal support mechanism includes two slide grooves symmetrically opened at the lower end of the extrusion plate, and second hydraulic telescopic rods are installed on the inner walls on the opposite sides of the two slide grooves. The telescopic ends of the two second hydraulic telescopic rods are fixedly connected with connecting plates, and each connecting plate is slidably connected to the corresponding inner wall of the slide groove.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] An internal support mechanism is provided, which can effectively avoid the interference of the support part on the coil assembly compared with the prior art. In addition, the use of two guide rods makes the downward movement of the extrusion disk more stable. In addition, the use of limit grooves replaces the limiting method of the clamping structure in the prior art, which not only reduces the operating steps, but also reduces the actual cost of the device.

[0019] The pressurizing mechanism also includes a first hydraulic telescopic rod 5 fixedly connected to the lower end of the horizontal plate 4, the telescopic end of the first hydraulic telescopic rod 5 is fixedly connected to a squeezing plate 7, and the first hydraulic telescopic rod 5 is a multi-section telescopic rod;

[0020] Among them, it also includes a guiding mechanism, which cooperates with the pressurizing mechanism. The guiding mechanism includes two guiding rods 6 symmetrically fixedly connected to the upper end of the extrusion plate 7. The upper end of the cross plate 4 is penetrated by two guiding openings 12. The two guiding rods 6 penetrate the corresponding guiding openings 12 and are slidably connected with the corresponding guiding openings 12. The use of the guiding mechanism can make the downward movement of the extrusion plate 7 more stable;

[0021] It also includes an internal support mechanism, which is located at the lower end of the extrusion plate 7. The internal support mechanism includes two slide grooves 10 symmetrically opened at the lower end of the extrusion plate 7. Second hydraulic telescopic rods 11 are installed on the inner walls of the opposite sides of the two slide grooves 10. The telescopic ends of the two second hydraulic telescopic rods 11 are fixedly connected with connecting plates 8, and each connecting plate 8 is slidably connected to the inner wall of the corresponding slide groove 10.

[0022] In the utility model, the rectangular motor housing is first placed in the limiting groove 2, and then the staff holds the coil and fits the upper end of the coil with the extrusion plate 7, and then starts the two second hydraulic telescopic rods 11 to extend, so that the two connecting plates 8 move back to back and support the coil from the inside, and then starts the first hydraulic telescopic rod 5 to move the entire coil downward until the coil is completely pressed into the motor housing. Since the motor housing is located in the limiting groove 2 and is only subjected to a force from top to bottom, the motor housing will not shake, and the stability of the motor housing is relatively strong. After the limiting is completed, the two second hydraulic telescopic rods 11 are started to retract, and the first hydraulic telescopic rod 5 is started to retract.
