[0016] 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.
[0017] Example: Figure 1-3As shown, this utility model provides a positioning device for a bearing pressing device for electric tricycles, including a positioning table 1, a positioning mechanism 2 on the inner side of the positioning table 1, and an inner support mechanism 3 fixedly mounted on the upper surface of the positioning table 1. The positioning mechanism 2 includes a motor 20, which is fixedly connected to one side of the positioning table 1. A bidirectional threaded rod 22 is fixedly mounted on the output end of the motor 20. Two symmetrically distributed positioning frames 27 are threaded on the outer side of the bidirectional threaded rod 22. A push plate 26 is fixedly mounted on the upper surface of the positioning frame 27, and a clamp 25 is fixedly mounted on one side of the push plate 26. In the bearing pressing device for electric tricycles, the bearing to be pressed is first placed on the positioning table 1 by means of the positioning mechanism 2. The bearing is positioned appropriately, and then the motor 20 is started. The output end of the motor 20 drives the bidirectional threaded rod 22 to rotate. Since the outer thread of the bidirectional threaded rod 22 is fitted with two symmetrically distributed positioning frames 27, as the bidirectional threaded rod 22 rotates, the two positioning frames 27 will move towards or away from each other along the positioning groove 23. The upper surface of the positioning frame 27 is fixedly provided with a push plate 26, and a clamp 25 is fixedly provided on one side of the push plate 26. Therefore, when the positioning frame 27 moves, it will drive the push plate 26 and the clamp 25 to move synchronously, thereby achieving precise positioning and clamping of the bearing. During the clamping process, the limiting block 24 at one end of the bidirectional threaded rod 22 can prevent it from coming off, ensuring the stability and reliability of the positioning.
[0018] The internal support mechanism 3 includes a base 30, the lower surface of which is fixedly connected to the positioning table 1. A fixing screw 34 is provided on the upper surface of the base 30. Two horizontally distributed sliding rings 35 are slidably arranged on the outer side of the fixing screw 34. Two rotating plates 32 are provided on the outer side of the sliding rings 35, with one end of each rotating plate 32 rotatably connected. A return spring 36 is fixedly provided on one end of each sliding ring 35. An adjusting nut 33 is threaded onto the upper end of the fixing screw 34. When further internal support is needed after the bearing is clamped by the positioning mechanism 2, the internal support mechanism 3 can be operated. First, by rotating the adjusting nut 33, it is adjusted to the position of the fixing screw 34. As the adjusting nut 33 moves downward, it compresses the return spring 36, simultaneously pushing the two sliding rings 35 downward along the fixed screw 34. A rotating plate 32 is located on the outer side of the sliding ring 35, and one end of each rotating plate 32 on the same side is rotatably connected. Therefore, when the sliding ring 35 slides downward, it causes the rotating plate 32 to unfold outward, thus providing support for the bearing's interior. The anti-slip pad 31 on one side of the rotating plate 32 increases friction with the bearing's inner wall, improving support stability. After the tightening operation is completed, the adjusting nut 33 is rotated in the opposite direction, the return spring 36 returns to its original state, and the sliding rings 35 and rotating plate 32 reset, facilitating bearing removal.
[0019] One side of the mounting bracket 21 is fixedly engaged with the motor 20, providing a stable mounting base for the motor 20 and ensuring that the motor 20 will not shake or shift during operation, thereby guaranteeing the accuracy and reliability of the positioning mechanism 2. The limiting block 24 is fixed to one end of the bidirectional threaded rod 22, effectively preventing the bidirectional threaded rod 22 from dislodging during movement, thus improving the stability and safety of the positioning mechanism 2. Positioning grooves 23 are provided on both sides of the positioning table 1, and the inner side of the positioning grooves 23 slides against the positioning frame 27, providing a precise moving track for the positioning frame 27, ensuring that the positioning frame 27 can move along a predetermined path, further improving the positioning accuracy of the positioning mechanism 2.
[0020] An anti-slip pad 31 is fixedly provided on one side of the rotating plate 32. When the rotating plate 32 unfolds to support the inside of the bearing, the anti-slip pad 31 can increase the friction with the inner wall of the bearing, preventing the bearing from sliding or shifting during the clamping process, thus improving the support effect and stability of the inner support mechanism 3. A sliding groove 37 is provided on the upper surface of the sliding ring 35, and the inner side of the sliding groove 37 is slidably engaged with the fixing screw 34, providing a stable sliding track for the sliding ring 35, ensuring that the sliding ring 35 can slide smoothly along the fixing screw 34, thereby ensuring the normal operation and adjustment accuracy of the inner support mechanism 3.
[0021] The motor 20 is existing technology and will not be described in detail here. In addition, this utility model also includes a power supply, a controller and a switch, which are not the main technical points of this patent and will not be described in detail here.
[0022] Working principle: In the bearing clamping equipment for electric tricycles, the bearing to be clamped is first placed in a suitable position on the positioning table 1 through the positioning mechanism 2. Then, the motor 20 is started, and the output end of the motor 20 drives the bidirectional threaded rod 22 to rotate. Since the outer thread of the bidirectional threaded rod 22 is fitted with two symmetrically distributed positioning frames 27, as the bidirectional threaded rod 22 rotates, the two positioning frames 27 will move towards or away from each other along the positioning groove 23. The upper surface of the positioning frame 27 is fixedly provided with a push plate 26, and a clamp 25 is fixedly provided on one side of the push plate 26. Therefore, when the positioning frame 27 moves, it will drive the push plate 26 and the clamp 25 to move synchronously, thereby achieving precise positioning and clamping of the bearing. During the clamping process, the limiting block 24 at one end of the bidirectional threaded rod 22 can prevent it from coming off, ensuring the stability and reliability of the positioning.
[0023] After the bearing is clamped by the positioning mechanism 2, if further internal support is needed, the internal support mechanism 3 can be operated. First, by rotating the adjusting nut 33, it moves downward on the fixed screw 34. Due to the movement of the adjusting nut 33, the return spring 36 is compressed, and at the same time, the two sliding rings 35 are pushed to slide downward along the fixed screw 34. The outer side of the sliding ring 35 is provided with a rotating plate 32, and one end of the two rotating plates 32 on the same side is rotatably connected. Therefore, when the sliding ring 35 slides downward, it will drive the rotating plate 32 to unfold outward, thereby achieving support for the inside of the bearing. The anti-slip pad 31 on one side of the rotating plate 32 can increase the friction with the inner wall of the bearing and improve the stability of the support. After the clamping operation is completed, the adjusting nut 33 is rotated in the opposite direction, the return spring 36 returns to its original state, and drives the sliding ring 35 and the rotating plate 32 to reset, making it easy to remove the bearing.
[0024] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
