[0036] This embodiment provides a C-type bushing installation kit, such as Figures 1-4 As shown, the set is used to assemble a C-type bushing 100 and a workpiece 200. Specifically, it includes a support mechanism 10, a positioning mechanism 20, and a press-fitting mechanism 30. The support mechanism 10 includes a bracket 11 and a carrier 12. The bracket 11 is arranged on the support surface, and the carrier 12 is arranged on the top of the bracket 11. The positioning mechanism 20 includes a base 21 and a positioning pin 22. The base 21 is arranged on the carrier 12. The positioning pin 22 is vertically protruded from the base 21 and can be inserted into the positioning hole 210 of the workpiece 200. The press-fitting mechanism 30 is used to press the C-type bushing 100 into the positioning hole 210. The press-fitting mechanism 30 is provided separately from the support mechanism 10, and the operator can hold the press-fitting mechanism 30 to assemble the C-type bushing 100 and the workpiece 200.

[0037] When using this set to assemble the C-type bushing 100 and the workpiece 200, the carrier 12 can ensure flatness and stability, and the positioning mechanism 20 is integrated with the carrier 12, which can position the workpiece 200 to prevent the workpiece 200 from shaking during the pressing process; in addition, since the pressing mechanism 30 and the support mechanism 10 are separately arranged, the operator can hold the pressing mechanism 30 and then press the C-type bushing 100 to the target position. The overall structure of the set is simple and the operation difficulty is low. Moreover, the workpiece 200 only needs to be fixed once before pressing, and the positioning effect is good and the pressing efficiency is high.

[0038] What needs to be explained here is that Figure 1 and Figure 4 As shown, the carrier 12 is provided with a limiting groove 121 along the circumference, and a plurality of positioning mechanisms 20 are provided in the limiting groove 121. The plurality of positioning mechanisms 20 are all movably connected to the limiting groove 121, and the movable distance of each positioning mechanism 20 in the extension direction of the corresponding limiting groove 121 does not exceed 0.5 mm. This arrangement can perform multiple positioning from the circumference of the workpiece 200, thereby ensuring the stability of the workpiece 200, avoiding shaking during the pressing process, and ensuring a good pressing effect. In addition, since the composite material has a certain deformation ability, it may happen that a certain positioning pin 22 cannot be inserted into the corresponding positioning hole 210, and the positioning mechanism 20 in this embodiment can move in the limiting groove 121. Therefore, the position of the positioning mechanism 20 can be fine-tuned to ensure that each positioning mechanism 20 can be plugged into a corresponding positioning hole 210, without the need for repeated positioning, and can ensure a good positioning effect.

[0039] It is further explained that if Figure 1 As shown, the bottom of the bracket 11 is provided with multiple pulleys 13 along the circumference, and each pulley 13 has a self-locking function. The provision of pulleys 13 facilitates the movement of the bracket 11. At the same time, after the press-fitting mechanism 30 completes the press-fitting of one side, the position of the bracket 11 can be directly rotated to rotate the remaining side to be installed to the target position, and then continue the press-fitting.

[0040] Specifically, if Figure 1 As shown, the press-fitting mechanism 30 includes a main body 31, a driving member 32, and a positioning sleeve 33, which are interconnected. The driving member 32 is disposed on the main body 31, and the positioning sleeve 33 is located at the end of the main body 31. The driving member 32 can drive the positioning sleeve 33 to move in the vertical direction to press the C-shaped bushing 100 into the positioning hole 210. The driving member 32 can directly drive the positioning sleeve 33 downward, eliminating the need for the operator to manually press the mechanism. This not only saves effort, but also ensures the same pressure value each time, thereby ensuring a good press-fitting effect.

[0041] In addition, in this embodiment, the driving member 32 is a driving cylinder. The cylinder is not only simple in structure, but also easy to install and operate, which is conducive to reducing manufacturing costs. Figure 3 As shown, a pneumatic switch 35 is also provided on the main body 31. When the operator presses the pneumatic switch 35, the driving member 32 can drive the positioning sleeve 33 to press down the C-shaped bushing 100, which is convenient and quick to operate.

[0042] like Figure 1 and Figure 3 As shown, the press-fitting mechanism 30 further includes a handle assembly 34, which is disposed on the main body 31. The operator can assemble the C-shaped bushing 100 and the workpiece 200 by holding the handle assembly 34 without directly holding the main body 31, thereby ensuring good stability.

[0043] In addition, if Figure 1 and Figure 3 As shown, the handle assembly 34 includes a first handle 341 and a second handle 342. The first handle 341 is provided at an end of the main body 31 away from the positioning sleeve 33, and the second handle 342 is provided at an end of the main body 31 close to the positioning sleeve 33. The operator can hold the first handle 341 with one hand and the second handle 342 with the other hand, thereby enabling the operator to hold the main body 31 from both ends, greatly improving the stability of the pressing operation.

[0044] In addition, if Figure 1 and Figure 3 As shown, the first handle 341 and the second handle 342 are respectively provided on two adjacent side surfaces of the main body 31. In this structure, the operator can hold the handle with both hands from different angles, thereby improving operability and convenience.

[0045] In addition, if Figure 1 and Figure 2 As shown, the positioning mechanism 20 further includes an elastic member 23, which is disposed within the base 21, with one end connected to or abutting the inner bottom of the base 21, and the other end connected to or abutting the end of the positioning pin 22 located within the base 21. During the insertion of the positioning pin 22 into the positioning hole 210, the workpiece 200 will abut the top end of the positioning pin 22 before the workpiece 200 abuts against it, thereby compressing the elastic member 23 downward, avoiding a rigid connection and improving positioning efficiency. In addition, when the positioning sleeve 33 presses down on the C-shaped bushing 100, the elastic member 23 can also provide a good buffering effect, preventing the positioning pin 22 from breaking.

[0046] It should be noted here that, in this embodiment, the elastic member 23 is a spring, which has a simple structure, is inexpensive, and is easy to install, thereby effectively reducing manufacturing costs.

[0047] Specifically, if Figure 2As shown, the base 21 is provided with a telescopic hole. One end of the positioning pin 22 is located in the base 21, and the other end passes through the telescopic hole. The end of the positioning pin 22 extending from the base 21 is provided with a guide portion 221. The diameter of the guide portion 221 gradually decreases as it moves away from the base 21. The provision of the guide portion 221 ensures that the positioning pin 22 is quickly inserted into the positioning hole 210, plays a good guiding role, and thus further improves positioning efficiency.

[0048] In addition, if Figure 2 As shown, the positioning pin 22 also includes an assembly portion 222 connected to the guide portion 221. The outer diameter of the assembly portion 222 is smaller than the inner diameter of the positioning hole 210 to form an assembly space, and a guide slope is provided at the top of the assembly portion 222. When the positioning sleeve 33 presses down the C-shaped bushing 100 and passes through the guide portion 221, the C-shaped bushing 100 can be pressed into the assembly space along the guide slope, thereby completing the assembly task. The provision of the guide slope can improve the convenience of assembly, thereby increasing the assembly speed and reducing the assembly difficulty.

[0049] In addition, if Figure 2 As shown, the positioning pin 22 further includes a limiting portion 223 connected to the assembly portion 222. The diameter of the assembly portion 222 is larger than the diameter of the telescopic hole. A slide groove 211 is provided in the base 21. The elastic member 23 is placed in the slide groove 211, and the limiting portion 223 slides and abuts against the inner wall of the slide groove 211. The limiting portion 223 not only prevents the positioning pin 22 from being completely separated from the base 21, but also slides and abuts against the slide groove 211, ensuring good guidance and stability of the positioning pin 22 in the vertical direction, thereby enabling the elastic member 23 to produce a good reset effect.

[0050] Combined with the attached figure, the workflow of this package is described:

[0051] First, the support mechanism 10 is moved to the support surface, and the workpiece 200 is moved onto the carrier 12 , so that the plurality of positioning pins 22 are aligned with the positioning holes 210 , thereby completing the positioning of the workpiece 200 ;

[0052] Next, a C-shaped bushing 100 is placed on a positioning pin 22. The operator holds the handle assembly 34 and presses the pneumatic switch 35. The driving member 32 drives the positioning sleeve 33 downward, and the positioning pin 22 can be inserted into the positioning sleeve 33. The bottom circumference of the positioning sleeve 33 can press the C-shaped bushing 100 into the assembly space.

[0053] Finally, the previous step is performed to complete the assembly of the entire C-type bushing 100.

[0054] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
