Description

Technical Field

[0001] This utility model belongs to the field of motor manufacturing, and specifically relates to a sealing ring press-fitting device for motor manufacturing housing. Background Technology

[0002] Currently, in the motor manufacturing process, to ensure the sealing of the spare motor housing, the sealing ring needs to be precisely pressed into the designated position on the housing. Traditional sealing ring pressing methods are mostly manual operations, using simple tools to knock or press. This method is not only inefficient and difficult to meet the needs of large-scale production, but also, due to the variability of manual operation, it is difficult to ensure that the pressing force and position are accurate and consistent each time. If the sealing ring is not pressed into place, it will lead to poor sealing of the motor during subsequent use, making it easy for water and dust to enter the motor, thereby affecting the motor's performance and service life.

[0003] Therefore, considering the shortcomings of the above-mentioned solutions in actual production and implementation, modifications and improvements have been made. In the spirit of striving for excellence, and with the assistance of professional knowledge and experience, and after much ingenuity and experimentation, this utility model was created. It provides a sealing ring pressing device for motor manufacturing housing, addressing the problem that traditional sealing ring pressing methods are mostly manual, using simple tools for tapping or pressing. This method is not only inefficient and difficult to meet the needs of large-scale production, but also, due to the variability of manual operation, it is difficult to ensure that the pressing force and position are accurate and consistent each time. If the sealing ring is not properly pressed, it will lead to poor sealing in the motor during subsequent use, making it easy for water and dust to enter the motor, thus affecting the motor's performance and service life.

Detailed Implementation

[0024] 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.

[0025] like Figures 1-6 As shown, a sealing ring press assembly device for motor manufacturing includes: an assembly table 1, and two horizontally arranged guide rail mechanisms 2 are fixedly connected to the left and right sides of the assembly table 1.

[0026] The guide rail mechanism 2 has a transverse groove inside, and a servo push rod A201 is fixedly connected inside the transverse groove. A movable frame 2011 is fixedly connected to the output end of the servo push rod A2011. The movable frame 2011 is arranged longitudinally, and a longitudinally arranged servo push rod B2013 is fixedly connected inside the movable frame 2011. A support frame 2014 is fixedly connected to the bottom end of the servo push rod B2013. A longitudinally arranged guide rod assembly 2016 is fixedly connected to the bottom surface of the support frame 2014. A guide ball assembly 2017 is rotatably connected to the bottom end of the guide rod assembly 2016.

[0027] The movable frame 2011 has two locations, which are arranged in parallel. The outer sides of each movable frame 2011 are fixedly connected to two slider assemblies 2012 with protruding structures. The movable frame 2011 and the slider assembly 2012 together form a movable structure. The outer side of the support frame 2014 is fixedly connected to two protrusion assemblies 2015 with protruding structures. The bottom surface of the assembly table 1 is equipped with a support leg assembly 101. The turntable assembly 301 has a circular cross-section. The top surface of the turntable assembly 301 has an annular groove for placing the housing assembly 3012. This annular groove is a slot 3011.

[0028] The support leg assembly 101 has four parts, which are fixedly connected to the four corners of the bottom surface of the assembly table 1. Each of the four support leg assemblies 101 has a pad assembly 1011 fixedly connected to its bottom surface. A servo motor 3 is installed on the bottom surface of the assembly table 1. An output shaft is provided at the top of the servo motor 3. A turntable assembly 301 is installed on the output shaft. A sealing ring 3013 is embedded at the top of the housing assembly 3012. The sealing ring 3013 is located directly below the ball guide assembly 2017. The guide rod assembly 2016 and the ball guide assembly 2017 together form a press-fit structure for the sealing ring 3013.

[0029] In use, first, place the housing assembly 3012 of the spare housing of the motor to be fitted with the sealing ring into the annular groove of the turntable assembly 301, ensuring that it is placed stably. At this time, the sealing ring 3013 embedded at the top of the housing assembly 3012 is located directly below the ball guide assembly 2017. The assembly table 1 is supported by the support leg assembly 101 installed on its bottom end surface. The support leg assembly 101 has four parts, which are fixedly connected to the four corners of the bottom end surface of the assembly table 1. The pad assembly 1011 on its bottom end surface plays a role in stabilizing support and preventing slippage.

[0030] The guide rail mechanism 2 is fixed on the left and right sides of the assembly table 1. The servo push rod A201 installed in the transverse groove inside it is activated. The output end of the servo push rod A201 pushes the moving frame 2011 to move laterally along the guide rail mechanism 2. The moving frame 2011 has two parallel positions. The slider assembly 2012 on its outer side slides on the guide rail mechanism 2 to ensure that the moving frame 2011 moves smoothly and is accurately adjusted to the appropriate transverse position to align with the sealing ring 3013 that needs to be pressed.

[0031] After the movable frame 2011 is positioned, the servo push rod B2013, which is longitudinally arranged inside the movable frame 2011, is activated. The bottom end of the servo push rod B2013 is connected to the support frame 2014. As the servo push rod B2013 extends, the support frame 2014 drives the guide rod assembly 2016 and the guide ball assembly 2017 to move downward together. The guide ball assembly 2017, which is rotatably connected to the bottom end of the guide rod assembly 2016, gradually approaches the sealing ring 3013. When it contacts the sealing ring 3013, the descending guide ball assembly 2017 applies pressure to the sealing ring 3013. Since the guide ball assembly 2017 is rotatably connected to the guide rod assembly 2016, during the pressing process, the guide ball assembly 2017 can adapt to the surface condition of the sealing ring 3013, so that the pressure is evenly distributed on the sealing ring 3013, ensuring that the sealing ring 3013 is accurately pressed into the designated position of the housing assembly 3012.

[0032] After the pressing is completed, the servo push rod B2013 retracts, driving the guide rod assembly 2016, the ball guide assembly 2017, and the support frame 2014 to rise and reset. Subsequently, the servo push rod A201 starts, driving the moving frame 2011 back to its initial position for the next pressing operation. If it is necessary to replace the spare housing of the motor with a different specification, the stroke of the servo push rod A201 and the servo push rod B2013 can be adjusted through the operation control device to adapt the device to different pressing requirements.
