Detailed implementation manners

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used in the description of this application in the specification are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the description and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order.

[0023] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0024] The embodiment of the present utility model provides a motor pressing device for an automotive steering column, as Figures 1-4 shown, including a support platform 1; an adjusting mechanism and a fastening mechanism provided on the support platform 1; the adjusting mechanism includes: a mounting bracket 2 provided on the support platform 1; an assembly seat 3 provided on one side of the mounting bracket 2; a strengthening bracket 4 provided on the side of the assembly seat 3 away from the mounting bracket 2; a threaded through hole 5 is formed in the strengthening bracket 4, and a lead screw 6 is in threaded fit with the threaded through hole 5; a pressing head 7 provided at the bottom of the lead screw 6; a protective member provided at the bottom side of the pressing head 7; wherein, the protective member includes: a plurality of return springs 8 provided at the bottom side of the pressing head 7; a damper provided in the plurality of return springs 8; a pressing plate 9 is provided on the side of the plurality of return springs 8 away from the pressing head 7.

[0025] It should be noted that since existing pressing devices often have problems such as poor adaptability, complex operation, and easy damage to motors, and cannot meet the high-precision and high-efficiency requirements of modern automobile manufacturing and maintenance, in this solution, through the design of the adjustable pressing head 7 and the anti-slip crank 10, it is ensured that the automobile steering column motor is evenly and stably pressed, effectively protecting the motor from damage. At the same time, the arc-shaped support plate 11 and the spacing adjustment function enable the device to adapt to motors of different sizes, improving adaptability and flexibility. In addition, the protective parts ensure the safety and stability of the pressing and releasing processes, improve work efficiency, and ensure the integrity and reliability of the motor during the pressing process.

[0026] Specifically, in this embodiment, this solution mainly includes a support table 1; an adjustment mechanism and a fastening mechanism provided on the support table 1; when it is necessary to press the automobile steering column motor, first place it on the support table 1 and fix it on the support table 1 through the fastening mechanism; next, by rotating the lead screw 6, the lead screw 6 rises or falls in the threaded through hole 5; the rise or fall of the lead screw 6 drives the pressing head 7 to move together, and the pressing head 7 then evenly applies the pressing force to the steering column motor to be pressed through the protective parts;

[0027] During the pressing process, the return springs 8 in the protective parts will be gradually compressed, and the elastic action of these return springs 8 can prevent the pressing head 7 or the pressing plate 9 from damaging the steering column motor due to excessive pressure; when the appropriate pressing force is reached, the rotation of the lead screw 6 can be stopped, and at this time the steering column motor is safely and firmly pressed;

[0028] In addition, the damper plays a role in slowing down the movement speed of the pressing head 7 during the pressing and releasing processes, helping to avoid impacting the steering column motor; when it is necessary to release the steering column motor, just rotate the lead screw 6 in the reverse direction, and the return spring 8 will push the pressing head 7 to rise under the elastic action, thereby releasing the steering column motor.

[0029] In a further preferred embodiment of the present invention, as Figures 1-3 shown, the adjustment mechanism further includes: a crank 10, the crank 10 is arranged at a position on the side of the lead screw 6 away from the pressing head 7; the outer surface of the crank 10 is provided with anti-slip patterns.

[0030] In this embodiment, the user can drive the rotation of the lead screw 6 in the threaded through hole 5 by manually rotating the crank 10; when it is necessary to press the automobile steering column motor, the user only needs to rotate the crank 10 clockwise, and the lead screw 6 will rise in the threaded through hole 5 accordingly, thereby driving the pressing head 7 to apply pressure to the component to be pressed;

[0031] Meanwhile, the outer surface of the crank 10 is provided with anti-slip patterns, which can increase the friction between the user's hand and the crank 10 and prevent the hand from slipping when rotating the crank 10. This can not only improve the stability of the operation, but also reduce the user's operation burden to a certain extent, making the pressing operation easier and more convenient.

[0032] In a further preferred embodiment of the present utility model, as Figure 1 shown, the fastening mechanism includes a group of support plates 11 arranged on the upper surface of the support table 1, and one of the support plates 11 is slidably engaged with the support table 1; placing grooves 12 are formed on both of the two support plates 11, and the placing grooves 12 are arc-shaped.

[0033] In this embodiment, when it is necessary to press the automotive steering column motor, first place it in the placing grooves 12 of the two support plates 11; since the placing grooves 12 are arc-shaped, they can closely fit the shape of the automotive steering column motor, thereby providing more stable and uniform support; one of the support plates 11 is designed to be slidable, which enables the support plate 11 to finely adjust the spacing along with the shape of the steering column motor to ensure that it can obtain stable and uniform support regardless of the size of the motor; such a design makes the pressing operation more accurate and reliable.

[0034] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, a side plate 13 is arranged on one side of the support table 1 adjacent to the sliding support plate 11, and an electric push rod 14 is arranged on the side of the side plate 13 opposite to the support plate 11, and the telescopic end of the electric push rod 14 is connected to the side wall of the side plate 13.

[0035] In this embodiment, when the electric push rod 14 extends, it will push the side plate 13 to move, and then drive the sliding support plate 11 to move away from the fixed support plate 11, thereby increasing the distance between the two support plates 11 to improve the flexibility of the device application.

[0036] In a further preferred embodiment of the present utility model, as Figures 1-3 shown, a guiding groove 15 for the sliding of the support plate 11 is formed on the upper surface of the support table 1.

[0037] In this embodiment, the guiding groove 15 provides a clear moving path and restriction for the sliding support plate 11, ensuring that the support plate 11 will not deviate from the predetermined trajectory during the sliding process. This design helps to improve the stability and accuracy of the sliding of the support plate 11.

[0038] In a further preferred embodiment of the present utility model, as Figure 4 shown, rubber pads 16 are arranged on the upper surface of the placing groove 12 and the bottom side of the pressing plate 9.

[0039] In this embodiment, the rubber pad 16 has high elasticity and can undergo elastic deformation within a certain range. When the pressing plate 9 presses the automotive steering column motor, the rubber pad 16 will produce corresponding elastic deformation to absorb and disperse the pressure applied to the motor, thus playing a buffering role. This buffering effect can effectively prevent the motor from being subjected to excessive impact and vibration, protecting its internal structure and performance.

[0040] In addition, the softness and elasticity of the rubber pad 16 also ensure good sealing and anti-slip effects between the pressing plate 9 and the motor. This helps prevent the motor from sliding or moving during the pressing process, thus ensuring the stability and accuracy of the pressing operation. This design not only improves the effect of the pressing operation but also extends the service life of the motor and related components.

[0041] Working principle: When this device is in use, place the automotive steering column motor in the placement grooves 12 of the two support plates 11. Due to the arc design of the placement grooves 12, they can closely fit the shape of the motor, providing stable and uniform support for the motor.

[0042] Next, if the distance between the support plates 11 needs to be finely adjusted according to the size of the motor, the electric push rod 14 can be operated to extend. The electric push rod 14 will push the side plate 13 to move, thereby driving the sliding support plate 11 to move away from the fixed support plate 11, thus increasing the distance between the two support plates 11. This design ensures that the motor can obtain stable and uniform support regardless of its size, ensuring that the motor does not move during the pressing process.

[0043] Next, the user can operate the pressing mechanism by manually rotating the crank 10. The outer surface of the crank 10 is provided with anti-slip patterns to increase the friction between the hand and the crank 10, preventing the hand from slipping when rotating the crank 10. This design improves the stability and ease of operation.

[0044] When it is necessary to press the motor, the user only needs to rotate the crank 10 clockwise. This action will drive the lead screw 6 to rise in the threaded through hole 5, and then drive the pressing head 7 to apply pressure to the motor to be pressed. The pressing head 7 evenly applies the pressing force to the motor through the protective member. During the pressing process, the return springs 8 in the protective member will be gradually compressed. The elastic action of these return springs 8 can prevent the pressing head 7 or the pressing plate 9 from damaging the motor due to excessive pressure.

[0045] In addition, the damper slows down the movement speed of the pressure head 7 during the pressing and releasing processes, which helps to avoid impacting the motor. When the appropriate pressing force is reached, the user can stop rotating the crank 10. At this time, the motor is safely and firmly pressed on the support plate 11. Finally, when the motor needs to be released, the user only needs to rotate the crank 10 in the reverse direction, and the return spring 8 will push the pressure head 7 to rise under the elastic action, thereby releasing the motor.
