Detailed Implementation

[0039] The following is in conjunction with the appendix Figures 1-13 The present invention will be described in further detail below.

[0040] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 This utility model provides a telescopic positioning pin quick-change mechanism, including a support 1, a guide rod 2 movably disposed in the support 1, and a hydraulic cylinder 10 disposed at the bottom of the support 1, with the piston rod of the hydraulic cylinder 10 connected to one end of the guide rod 2.

[0041] The top of the support 1 is equipped with a quick-change locating pin structure, which includes a locating pin. The bottom end of the locating pin is hooked to the other end of the guide rod 2. The support body is sleeved on the outside of the locating pin and can be detachably installed on the top of the support 1.

[0042] Example 1, based on the same concept described above, see... Figure 2 The telescopic positioning pin quick-change mechanism is as follows: the positioning pin is a diamond pin 8, the bottom end of the diamond pin 8 is hooked and connected to the other end of the guide rod 2; the support body is a diamond pin support 7, the diamond pin support 7 is inserted and installed on the top of the support 1 and fixed by screws, which facilitates quick disassembly and installation.

[0043] A guide groove 11 is provided on the outer wall of the rhombus pin 8. A guide pin 12 is threadedly connected to the side of the rhombus pin support 7. The guide pin 12 extends into the guide groove 11 to guide the rhombus pin 8 when it moves in and out of the rhombus pin support 7, thus preventing the possibility of rotation. An O-ring seal 9 is installed at the top of the rhombus pin support 7. The O-ring seal 9 is sleeved on the outside of the rhombus pin 8 to improve the sealing between the rhombus pin support 7 and the rhombus pin 8.

[0044] Working principle: The diamond pin support 7 is fitted onto the diamond pin 8, and then the diamond pin 8 is hooked and connected to the guide rod 2. The diamond pin support 7 is then fixed on the support 1. The hydraulic cylinder 10 drives the guide rod 2 to move up and down on the support 1. The up and down movement of the guide rod 2 drives the diamond pin 8 to move up and down and extend and retract on the diamond pin support 7, so as to achieve the purpose of use.

[0045] Example 2, based on the same concept described above, see... Figure 1 The telescopic positioning pin quick-change mechanism: the support body is an expansion pin support 3, which is inserted into the top of the support 1 and fixed by screws, which facilitates quick disassembly and installation between the expansion pin support 3 and the support 1.

[0046] The positioning pin includes a lifting shaft 4 and two lifting pins 6. The bottom end of the lifting shaft 4 is hooked to the other end of the guide rod 2. The two lifting pins 6 are symmetrically arranged on both sides of the outer side of the lifting pin support 3. One end of the lifting pin 6 is inclined and slidably connected to the lifting shaft 4. When the lifting shaft 4 moves vertically, it is convenient to drive the lifting pin 6 to move laterally on the lifting pin support 3. The top of the lifting pin support 3 is provided with a waterproof cover 5 to facilitate waterproofing and prevent water stains from entering its inner cavity from the top of the lifting pin support 3.

[0047] See Figure 6 , Figure 7 and Figure 8 The upper left and right sides of the outer wall of the expansion pin support 3 are symmetrically provided with movable telescopic through holes 301 that cooperate with the expansion pin 6, so that the expansion pin 6 can move laterally and telescopically on the expansion pin support 3.

[0048] See Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 One end of the expansion pin 6 is provided with a slider 601. The cross-section of the slider 601 is an isosceles trapezoid. The top of the outer wall of the expansion shaft 4 is symmetrically provided with inclined grooves 401 that cooperate with the slider 601. The top of the grooves 401 extends to the top of the expansion shaft 4. The slider 601 slides in the inclined grooves 401, which facilitates the conversion of the vertical movement of the expansion shaft 4 into the horizontal extension and retraction movement of the expansion pin 6.

[0049] Working principle: First, the expansion shaft 4 is hooked and connected to the guide rod 2. Then, the expansion pin support 3 is put on the expansion shaft 4 and the expansion pin 6 is connected to the expansion shaft 4. Then, the expansion pin support 3 is fixed on the support 1. The hydraulic cylinder 10 drives the guide rod 2 to move up and down in the support 1. The up and down movement of the guide rod 2 drives the expansion shaft 4 to move up and down in the expansion pin support 3. The up and down movement of the expansion shaft 4 drives the two expansion pins 6 to extend and retract laterally on the expansion pin support 3, so as to achieve the purpose of use.

[0050] In summary, based on support 1 and guide rod 2, different types of cylindrical pins are first hooked and connected to guide rod 2, and then the corresponding support body is selected to fix them. The guide rod 2 is extended and retracted by hydraulic cylinder 10 to further extend and retract the cylindrical pins. By quickly removing the support body and the corresponding cylindrical pin, the purpose of replacing it with another type of cylindrical pin can be achieved. This facilitates the extension and retraction of different types of positioning pins and allows for quick switching between them, improving the adaptability of different types of positioning pins in field use.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
