[0026] 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.

[0027] Please see Figure 1-5 The present invention provides the following technical solution:

[0028] An automatic bushing assembly mechanism includes a base plate 1, an mounting sleeve 2 on the top of the base plate 1, a bushing body 3 on the top of the mounting sleeve 2, a pressure plate 4 on the top of the bushing body 3, a top support mechanism 8 on both sides of the bottom of the pressure plate 4, a rotation mechanism 9 on the top of the pressure plate 4, and a first electric telescopic rod 6 on the top of the base plate 1.

[0029] The rotating mechanism 9 includes a first screw 901, two nuts 902, a rotating drum 903, and a second screw 904. The first screw 901 and the second screw 904 are both threadedly connected to the inside of the rotating drum 903. The threads on the surfaces of the first screw 901 and the second screw 904 are arranged in opposite directions. The nuts 902 are fixedly sleeved on the surface of the rotating drum 903.

[0030] In this embodiment: By placing the mounting sleeve 2 between the two clips 19 at the top of the base plate 1, the controller 7 and synchronizer 12 control the two second electric telescopic rods 13 to extend synchronously, so that the clips 19 clamp the mounting sleeve 2, ensuring that its center point corresponds to the center point of the pressure plate 4. Then, the bushing body 3 is moved to a suitable position, so that the two pressure blocks 802 are inside the bushing body 3. The nut 902 is turned with an external wrench. Because the threads of the first screw 901 and the second screw 904 are opposite, the rotation of the nut 902 drives the rotating drum 903 to rotate, so that the first screw 901 and the second screw 904 move synchronously in opposite directions. The slider 801 slides in the through groove 11 of the pressure plate 4, pushing the pressure block 802, so that the rubber column 803 is in close contact with the inner wall of the bushing body 3, and the bushing body 3 is tightened and fixed in the position corresponding to the center point of the pressure plate 4, ensuring that the center of the bushing body 3 is aligned with the center of the mounting sleeve 2. Finally, the controller 7 controls the... The first electric telescopic rod 6 extends, causing the pressure plate 4 and the fixed bushing body 3 to move downwards. The pressure block 802, through contact between its surface and the top of the bushing body 3, pushes the bushing body 3 to accurately press into the mounting sleeve 2. After the bushing body 3 is fully pressed in, the first electric telescopic rod 6 stops, completing the assembly. The nut 902 is rotated in the opposite direction, causing the rubber column 803 to disengage from the inner wall of the bushing body 3, allowing for disassembly. This process eliminates the need for precise alignment due to the different sizes of the bushing body 3 and the mounting sleeve 2, saving alignment time, improving the assembly efficiency of the bushing body 3, and preventing damage to the bushing body 3. It solves the problem in existing patents where it is inconvenient to align the bushing and mounting parts. Due to the different sizes of the bushings, it is inconvenient to align the bushing with the matching mounting parts, which can easily lead to damage during the pressing process of the bushing and affect the efficiency of automatic pressing and assembly of the bushing.

[0031] Specifically, such as Figure 2As shown, the top support mechanism 8 includes a slider 801, a pressure block 802, and several rubber pillars 803. The bottom of the slider 801 is fixedly connected to the top of the pressure block 802. The surface of the pressure block 802 is in contact with the top of the bushing body 3. The rubber pillars 803 are fixedly connected to the surface of the pressure block 802. The surface of the rubber pillars 803 is in close contact with the inner wall of the bushing body 3. The first screw 901 is fixedly connected to the left slider 801 near the left slider 801. The second screw 904 is fixedly connected to the right slider 801 near the right slider 801.

[0032] Specifically, such as Figure 2 As shown, both sides of the top of the pressure plate 4 are provided with through grooves 11, and the slider 801 is slidably connected inside the through grooves 11.

[0033] Specifically, such as Figure 3 and Figure 4 As shown, a support block 17 is fixedly connected to the top of the pressure plate 4, and a rotating cylinder 903 is rotatably connected inside the support block 17. A limiting ring 18 is fixedly sleeved on the surface of the rotating cylinder 903. There are two limiting rings 18, and the surface of the limiting ring 18 is in contact with the surface of the support block 17.

[0034] In this embodiment: by sliding the slider 801 inside the through groove 11, the first screw 901 and the second screw 904 can easily drive the slider 801 and the pressure block 802 to move when the nut 902 is rotated, so that the surface of the rubber column 803 is in close contact with the inner wall of the bushing body 3, thus fixing the bushing body 3 at the center point corresponding to the center point of the pressure plate 4. The rotating cylinder 903 is rotatably connected to the inside of the support block 17, and the limiting ring 18 limits the left and right positions of the rotating cylinder 903, thus making the rotation of the rotating cylinder 903 more stable.

[0035] Specifically, such as Figure 1 and Figure 5 As shown, a second electric telescopic rod 13 is fixedly connected to both sides of the top of the base plate 1. A bracket 19 is fixedly connected to the telescopic end of the second electric telescopic rod 13. The surface of the bracket 19 is in close contact with the surface of the mounting sleeve 2.

[0036] Specifically, such as Figure 1 As shown, a bracket 16 is fixedly connected to the top of the base plate 1, the top of the first electric telescopic rod 6 is fixedly connected to the surface of the bracket 16, a fixing frame 5 is fixedly connected to the bottom of the telescopic end of the first electric telescopic rod 6, and the bottom of the fixing frame 5 is fixedly connected to the top of the pressure plate 4.

[0037] In this embodiment: by placing the mounting sleeve 2 between the two opposing sides of the two clips 19 on the top of the base plate 1, and then controlling the extension ends of the two second electric telescopic rods 13 to extend synchronously through the controller 7 and the synchronizer 12, the surface of the clips 19 is in close contact with the surface of the mounting sleeve 2, so that the mounting sleeve 2 can be clamped until the center point corresponds to the center point of the pressure plate 4. After the bushing body 3 and the mounting sleeve 2 are fixed, the controller 7 controls the first electric telescopic rod 6 to extend, and the fixing frame 5 drives the pressure plate 4 and the fixed bushing body 3 to move downward. By the surface of the pressure block 802 contacting the top of the bushing body 3, the bushing body 3 can be accurately pressed into the mounting sleeve 2.

[0038] Specifically, such as Figure 1 As shown, a synchronizer 12 is fixedly connected to the top of the base plate 1, a controller 7 is fixedly connected to the top of the bracket 16, a first support plate 15 is fixedly connected to the surface of the bracket 16, a second support plate 10 is fixedly connected to the rear side of the bracket 16, and the bottom of the second support plate 10 is fixedly connected to the top of the base plate 1.

[0039] Specifically, such as Figure 1 As shown, a support block 14 is fixedly connected to the bottom of the base plate 1. The support block 14 is a number and is evenly distributed on the bottom of the base plate 1.

[0040] In this embodiment: the synchronizer 12 and the controller 7 can conveniently and precisely control the first electric telescopic rod 6 and the two second electric telescopic rods 13, the first support plate 15 and the second support plate 10 can stably support the bracket 16, and the support block 14 can stably support the base plate 1 by placing the base plate 1 on a stable external workbench.

[0041] Working principle: By placing the mounting sleeve 2 between the two opposing sides of the two clips 19 on the top of the base plate 1, and then controlling the extension ends of the two second electric telescopic rods 13 to extend synchronously through the controller 7 and synchronizer 12, the surface of the clips 19 is brought into close contact with the surface of the mounting sleeve 2, thus clamping the mounting sleeve 2 until its center point corresponds to the center point of the pressure plate 4. Then, the bushing body 3 is moved until the two pressure blocks 802 are inside the bushing body 3. Then, the nut 902 is turned using an external wrench. Because the threads on the surfaces of the first screw 901 and the second screw 904 are opposite, when the nut 902 is turned, it drives the first screw 901 and the second screw 904 to move synchronously in opposite directions. At this time, the slider 801 slides in the through groove 11 of the pressure plate 4, pushing the pressure blocks 802 on both sides to move synchronously, so that the rubber pillars 803 on the pressure blocks 802 are brought into close contact with the inner wall of the bushing body 3, thereby tightening and fixing the bushing body 3 at the position corresponding to the center point of the pressure plate 4. At this time, the center position of the bushing body 3 and the mounting sleeve 2 body will correspond. Then, by controlling... The device 7 controls the extension of the first electric telescopic rod 6, which drives the pressure plate 4 and the fixed bushing body 3 to move downward through the fixing frame 5. The surface of the pressure block 802 contacts the top of the bushing body 3, thus accurately pressing the bushing body 3 into the mounting sleeve 2. When the bushing body 3 is fully pressed into the mounting sleeve 2, the first electric telescopic rod 6 stops moving and rotates the nut 902 in the opposite direction, causing the rubber column 803 to disengage from the inner wall of the bushing body 3, allowing for disassembly. This completes the entire automatic assembly process, saving time required for precise alignment when the bushing body 3 and the mounting sleeve 2 are different sizes, improving the assembly efficiency of the bushing body 3. It solves the problem in existing patents where it is inconvenient to align the bushing and the mounting part. Due to the different sizes of the bushings, it is inconvenient to align the bushing with the matching mounting part, which can easily lead to damage during the pressing process of the bushing and affect the efficiency of automatic pressing and assembly of the bushing. It should be noted that the synchronizer 12 and the controller 7 are existing and mature technologies that have been published, and will not be described in detail here.

[0042] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
