[0053] The body 1 comprises a circular ring structure, and is provided with a positioning assembly mounting threaded hole 11 and an adjustment assembly mounting threaded hole 12 .

[0054] The adjustment component 2 includes a mounting block 21, a pin sleeve 22, an adjustment block 23, and a measuring pin 24. The mounting block 21 is provided with an adjustment component mounting through hole 25 that matches the adjustment component mounting threaded hole 12; the mounting block 21 is provided with an adjustment block mounting threaded hole 210, and the adjustment block 23 is provided with an adjustment block mounting through hole 29 that matches the adjustment block mounting threaded hole 210. The adjustment block 23 is fastened to the mounting block 21 by screws.

[0055] The mounting block 21 is provided with a mounting block pin sleeve mounting hole 27 matching the pin sleeve 22, and the pin sleeve 22 is fastened and mounted on the mounting block 21; the adjustment block 23 is provided with an adjustment block measuring pin hole 28 matching the measuring pin 24, and the measuring pin 24 includes a segmented pin, the small diameter section cooperates with the pin sleeve 22, and the large diameter section cooperates with the adjustment block 23.

[0056] After the main body 1 and the adjustment component 2 are installed in place, three-coordinate precision measurement is performed to adjust the installation position of the adjustment component 2 to ensure the accuracy of the pin sleeve hole position of the mounting block pin sleeve mounting hole 27, and then install the pin sleeve 22. Then, positioning pin holes are drilled between the mounting block 21 and the main body 1, and between the adjustment block 23 and the mounting block 21 to ensure the accuracy of the installation position.

[0057] The pin sleeve hole position accuracy includes the hole distribution angle, the distance from the installation surface and the flatness of the pin hole fitting surface. All accuracy indicators should be better than the accuracy requirements of the actual product's lower fulcrum installation.

[0058] The mounting and positioning assembly 3 includes a mounting seat 31, a positioning block 32, a positioning pin 33 and a limit pin 34. The mounting seat 31 is provided with a mounting and positioning assembly mounting through hole 36 that matches the mounting and positioning assembly mounting threaded hole 11; the mounting seat 31 is provided with a positioning block mounting hole 35 that matches the positioning block 32, and the positioning block 32 is mounted on the mounting seat 31 by screws.

[0059] After the main body 1, the mounting seat 31 and the positioning block 32 are installed in place, combined processing is performed, and a positioning pin hole and a limit pin hole matching the product docking frame 6 are opened on the positioning block 32, and the positioning pin 33 and the limit pin 34 are installed accordingly, and the mounting surface 37 matching the product docking frame 6 is processed to ensure that the main body 1 is coaxial with the product after installation. The positioning pin hole is matched according to the actual pin hole position on the product installation surface, the limit pin hole is matched according to the inner diameter size of the product, and the positioning block installation surface 37 is combined and processed according to the product installation surface.

[0060] There are no less than 3 positioning pin holes, and the gaps between all limit pins and the inner diameter of the product docking frame are consistent.

[0061] Preferably, there are 6 sets of adjustment components 2 and 3 sets of installation and positioning components 3. The body 1 is provided with 6 sets of adjustment component installation threaded holes 12 and 3 sets of installation threaded holes 11 of the installation and positioning components.

[0062] After the main body 1, the mounting seat 31 and the positioning block 32 are installed in place, they are combined and processed. The positioning pin holes and the limit pin holes on the positioning block are made through the product docking frame 6, and the positioning pins 33 and the limit pins 34 are installed. The mounting surfaces 37 of the positioning block and the product are processed at 3 locations to ensure that the main body and the product are coaxial after installation. After the main body 1 and the adjustment component 2 are installed in place, three-coordinate precision measurement is carried out to adjust the installation position of the 6 adjustment components to ensure the accuracy of the 6 pin sleeve holes 27. The accuracy of the 6 pin sleeve holes, including the hole distribution angle, the distance from the installation surface, and the flatness index of the 6 pin hole fitting surfaces, should be better than the accuracy requirements of the actual product lower fulcrum adjustment, and then the pin sleeve 22 is installed.

Finally, the assembly of the lower fulcrum posture adjustment tooling and the shape and position accuracy are completed, that is, it is ensured that the lower fulcrum theoretical position 4 and the lower fulcrum indirect measurement pin hole 5 have a corresponding relationship, and the lower fulcrum indirect measurement pin hole 5 posture accuracy is better than the lower fulcrum theoretical position 4 posture accuracy.

[0063] Since the six lower fulcrum mechanisms of the docking mechanism are all distributed on the inner side of the docking frame 6, installation and adjustment are difficult and the installation accuracy cannot be directly measured. The tooling structure of the present application is simple. The precision of the lower fulcrums that cannot be directly measured is converted into high-precision installation and adjustment tooling by utilizing the precision measuring holes and measuring surfaces on the docking frame 6, which simplifies the operation process and reduces the difficulty of installation and adjustment of the lower fulcrum mechanism.

[0064] The position accuracy of the pin hole corresponding to the lower fulcrum of the product on the adjustment component 2 is better than the adjustment index accuracy of the lower fulcrum. When in use, after the lower fulcrum mechanism 7 and the product are installed in place, the reference surface and reference hole on the product are used to install the lower fulcrum posture adjustment tooling and the product by installing the positioning component 3; the cooperation between the measuring pin 24 on the adjustment component 2 and the indirect measurement pin hole 5 of the lower fulcrum of the product is used, and the installation position of the lower fulcrum mechanism 7 of the product is adjusted by adjusting the gasket to achieve the lower fulcrum installation posture adjustment; after adjustment in place, the positioning pin hole of the lower fulcrum mechanism 7 is drilled to ensure its installation position accuracy. The tooling structure of the present application is simple in form, and the accuracy of the lower fulcrum that cannot be directly measured is converted into a high-precision adjustment tooling to ensure it. It is easy to operate, reduces the difficulty of adjusting the lower fulcrum mechanism, and ensures the installation accuracy of the lower fulcrum mechanism of the docking mechanism.

[0065] Example 2

[0066] Based on Example 1, a method for adjusting the position and posture of the lower fulcrum of a docking mechanism provided by the present invention, using the tooling for adjusting the position and posture of the lower fulcrum of the docking mechanism of Example 1, comprises the following steps:

[0067] Step 1: Install the lower fulcrum mechanism 7 and the product docking frame 6, manually tighten the mounting screws of the lower fulcrum mechanism 7, and temporarily do not use adjustment gaskets at the installation joints between the lower fulcrum mechanism 7 and the docking frame 6;

[0068] Step 2: Install the tooling and the product by matching the positioning pin 33, the limit pin 34 and the mounting surface 37 on the mounting positioning assembly 3 with the product docking frame 6;

[0069] Step 3: Use the measuring pin 24 to indirectly measure the fit between the pin hole 5 of the lower fulcrum to indirectly measure the position and posture accuracy of the lower fulcrum;

[0070] Step 4: If the measuring pin 24 and the lower fulcrum indirect measuring pin hole 5 cannot fit smoothly, the lower fulcrum posture accuracy does not meet the requirements. Use an adjustment shim at the installation and matching position of the lower fulcrum mechanism 7 and the docking frame 6, and repeat step 3 until the measuring pin 24 and the lower fulcrum indirect measuring pin hole 5 fit smoothly.

[0071] Step 5: After the lower fulcrum posture accuracy is adjusted to meet the requirements, a positioning pin is provided between the lower fulcrum mechanism 7 and the docking frame 6;

[0072] Step 6: Remove the lower fulcrum posture adjustment tooling and complete the lower fulcrum posture adjustment

[0073] There are deviations in the machining of each set of product docking frames. When the tooling of this application is installed with the product docking frame, there are no less than 3 positioning pin holes on the installation positioning component 3. According to the actual installation situation, 2 holes can be installed, but the gap between the limit pins 34 at each location and the inner diameter of the product docking frame must be consistent.

[0074] The tooling structure of the present application is simple in form, and utilizes the precision measuring holes and measuring surfaces on the docking frame to convert the lower fulcrum accuracy that cannot be directly measured into a high-precision adjustment tooling to ensure it, thereby simplifying the operating process, reducing the difficulty of adjustment of the lower fulcrum mechanism, and providing a new adjustment solution for ensuring the position and posture of the lower fulcrum mechanism.
