[0042] like Figures 1-10As shown, this embodiment provides a shear key installation method. The installation structure of the shear key 600 includes a main body 100, a first screw 200, a second screw 300, a sleeve seat 400, a base 500 and the shear key 600. The main body 100 includes a first mounting plate 110 and a second mounting plate 120. The first screw 200 connects the sleeve seat 400 and the first mounting plate 110 of the main body 100. The base 500 connects the sleeve seat 400 and the second mounting plate 120 of the main body 100. The shear key 600 is installed on the base 500 and is connected to the sleeve seat 400 through the second screw 300. The shear key installation method includes the following steps:

[0043] S100, the first screw 200 connects the first mounting plate 110 and the sleeve seat 400, and the first screw 200 is screwed into the sleeve seat 400 by a first preset distance A;

[0044] S200 and the base 500 are welded to the sleeve seat 400 and the second mounting plate 120 respectively. The sleeve seat 400 is arranged between the first mounting plate 110 and the base 500, and the distance between the first side surface 530 of the base 500 facing away from the first mounting plate 110 and the first end surface 210 of the first screw 200 in the sleeve seat 400 is a second preset distance B;

[0045] S300 , the second screw 300 connects the shear key 600 and the sleeve seat 400 from the side facing away from the first mounting plate 110 .

[0046] By controlling the first preset distance A of the first screw 200 when screwed into the sleeve seat 400, the accuracy of the first screw 200 being the preset distance in the sleeve seat 400 is improved. Since the first side surface 530 is used to closely mate with the end surface of the shear key 600, by controlling the second preset distance B between the first side surface 530 and the first end surface 210 based on the first side surface 530, the accuracy of the relative installation position of the sleeve seat 400 and the base 500 is improved, thereby improving the accuracy of the mating between the sleeve seat 400 and the second screw 300, and improving the length accuracy of the second screw 300 screwed into the sleeve seat 400. The ends of the first screw 200 and the second screw 300 in the sleeve seat 400 meet the gap 721 requirement, preventing interference from affecting the installation of the second screw 300, and ensuring that the shear key 600 can be installed. The specific measurement method of the first preset distance A and the second preset distance B can be referred to the existing technology and will not be repeated here.

[0047] In one embodiment, the sleeve seat 400 has a length of 185 mm, a first preset distance A of 85 mm, and a second preset distance B of 120 mm. The distance that the second screw 300 screws into the sleeve seat 400 is 85 mm. Within the sleeve seat 400, the distance between the ends of the first screw 200 and the second screw 300 is 15 mm, meeting the clearance 721 requirement.

[0048] The length of the sleeve seat 400 is a key control point and must be inspected and qualified after processing before proceeding to the next process.

[0049] In step S200, first determine the installation position of the sleeve seat 400 on the base 500, ensure that the distance between the first side surface 530 and the first end surface 210 is the second preset distance B, and weld the sleeve seat 400 and the base 500; then adaptively weld with the second mounting plate 120 according to the position of the base 500.

[0050] In one embodiment, the base 500 is provided with a concentrically arranged recessed groove 510 and a connecting hole 520, the sleeve seat 400 is provided in the recessed groove 510, and the second screw 300 passes through the connecting hole 520 and the sleeve seat 400 to be connected to the sleeve seat 400; in step S200, the following is further included:

[0051] S210: Adjust the depth of the sleeve seat 400 in the recessed groove 510 so that the distance between the first side surface 530 and the first end surface 210 of the first screw 200 is the second predetermined distance B. The second mounting plate 120 is then welded to the base 500. The recessed groove 510 facilitates adjustment of the distance between the first side surface 530 and the first end surface 210 to the second predetermined distance B, thereby reducing the machining precision requirements for the second mounting plate 120 and the sleeve seat 400, as well as the precision requirements for the first screw 200 being screwed into the sleeve seat 400 to the first predetermined distance A. This reduces assembly requirements and thus reduces costs.

[0052] Generally, the span of the first mounting plate 110 and the second mounting plate 120 is relatively large, resulting in a large gap between the first screw 200 and the sleeve seat 400. The second screw 300 passes through the shear key 600, the base 500, and the sleeve seat 400, passing through multiple holes. This means that both the first screw 200 and the second screw 300 must pass through multiple holes and have a long span, requiring high structural precision. For example, if the screw specification is M56*1050, it can be either a screw or a bolt, without limitation. In one embodiment, mounting holes are provided on the first mounting plate 110, the second mounting plate 120, and the shear key 600 of the mainboard. Twelve mounting holes are provided on the first mounting plate 110, the second mounting plate 120, the shear key 600, and the recessed grooves 510 and connecting holes 520 on the base 500, respectively. These holes are arranged in a one-to-one correspondence to connect with the twelve first screws 200 and the twelve second screws 300. The mounting holes are concentric with the recessed grooves 510 and connecting holes 520 on the base 500. After machining, the shear key 600, the base 500, and the first mounting plate 110 and the second mounting plate 120 must be inspected for concentricity before proceeding to other processes to ensure the subsequent installation of the first screws 200 and the second screws 300.

[0053] In one embodiment, the base 500 is provided with a groove 540, and the shear key 600 is provided with a boss 610. The boss 610 is disposed within the groove 540, with a clearance fit between the boss 610 and the groove 540. The height C of the boss 610 is greater than the depth D of the groove 540, ensuring a tight fit between the shear key 600 and the first side surface 530. The roughness of the peripheral side surface of the boss 610 and the sidewalls of the groove 540 are the same, and both are less than the roughness of the top surface of the boss 610 and the roughness of the bottom wall of the groove 540.

[0054] In one embodiment, the peripheral side surface of the boss 610 is an inclined surface, and the side wall of the groove 540 is a matching inclined surface. The groove opening of the groove 540 is larger than the cross-sectional area of ​​the groove bottom. The inclined surface has a guiding function to facilitate the installation and disassembly of the boss 610 and the groove 540.

[0055] When processing the base 500 and the shear key 600, the process is transferred after the size and roughness of the groove 540 and the boss 610 are tested and qualified.

[0056] The welding deformation of the base 500 and the main body 100 makes it difficult for the flatness of the first side surface 530 to meet the requirements, thereby causing the shear key 600 to fail to meet the installation requirements. In one embodiment, after step S200, the following steps are further included:

[0057] Step S220 , detecting whether the flatness of the first side surface 530 is a preset value, such as using a laser plane measuring instrument to measure the flatness of the first side surface 530 of the base 500 .

[0058] If yes, proceed to step S300;

[0059] If not, the first side surface 530 of the base 500 is corrected until the flatness of the first side surface 530 reaches a preset value.

[0060] Due to structural space limitations, the first side surface 530 cannot be machined on a machine tool. In one embodiment, step S220 also includes: coloring the first side surface 530 with red lead on the blending block 700, and polishing the first side surface 530 to correct its flatness.

[0061] Since the cross-sectional area of ​​the base 500 is relatively large, such as the length and width dimensions of 2000mm*450mm, the traditional matching plate is small in size and cannot meet the flatness requirement of 1.0mm for large-surface matching. In one embodiment, the matching block 700 includes a flat plate 710 and a limit block 720 provided on the flat plate 710. The limit block 720 and the boss 610 are consistent in shape, size and roughness. The flat plate 710 can cover the first side 530, and the flatness of the flat plate 710 is not greater than the flatness of the first side 530. Step S220 also includes: the limit block 720 is limited to the groove 540, and the first side 530 is colored with red lead on the flat plate 710. By increasing the area of ​​the flat plate 710 so that it covers the first side 530, the flatness requirement of 1.0mm for large-surface matching can be met. Based on the flatness data measured by the laser plane measuring instrument, the first side surface 530 of the base 500 is tinted with red lead on the flat plate 710. Once the flatness of the first side surface 530 meets the 1.0mm requirement, the corresponding shear key 600 is installed. The calibration and installation of the other shear keys 600 are completed in the same manner.

[0062] Due to the large cross-sectional area of ​​the flat panel 710, the whisking block 700 includes reinforcing ribs 740 on the side of the flat panel 710 facing away from the stop block 720 to enhance structural strength and prevent deformation. Optionally, the whisking block 700 is constructed of aluminum, such as 2A02 duralumin, which ensures the strength of the entire whisking block 700. Due to the large size and weight of the flat panel 710, such as approximately 39 kg, the whisking block 700 optionally includes at least two gripping structures 730 on the side of the flat panel 710 facing away from the stop block 720, enabling at least two people to operate the whisking block 700 simultaneously.

[0063] Optionally, the reinforcing ribs 740 include transverse ribs 741 and longitudinal ribs 742 , which are respectively arranged crosswise along the transverse and longitudinal directions of the flat plate 710 . The number of the transverse ribs 741 and longitudinal ribs 742 can be set according to needs and is not limited.

[0064] In one embodiment, the manufacturing method of the whisk-matching block 700 includes: cutting and manufacturing the aluminum plate 710 according to the above structure, and transferring the plate to another process after passing inspection. If the groove 540 and the boss 610 have inclined surfaces, the stopper 720 of the whisk-matching block 700 is machined to form corresponding inclined surfaces. After passing inspection, the plate is transferred to another process and sent to a testing agency for standardization. Once qualified, the plate can be used.

[0065] Optionally, in the initial stage, the first side surface 530 is rough-machined according to the measurement data of the laser plane measuring instrument, and then the first side surface 530 is fine-machined using the fitting block 700, which reduces the use frequency of the fitting block 700 and reduces wear.

[0066] The base 500 and the second mounting plate 120 are welded in a symmetrical manner. Figure 6 As shown, the symmetrical welding sequence of ①-②, ③-④... is controlled to effectively control welding deformation and reduce subsequent re-processing of the first side surface 530.

[0067] This embodiment provides a ship, including a main body 100, a first screw 200, a second screw 300, a sleeve seat 400, a base 500 and a shear key 600. The main body 100 includes a first mounting plate 110 and a second mounting plate 120. The base 500 connects the sleeve seat 400 and the second mounting plate 120. The sleeve seat 400 is arranged between the base 500 and the first mounting plate 110. The first screw 200 connects the first mounting plate 110 and one side of the sleeve seat 400. The second screw 300 connects the shear key 600 and the other side of the sleeve seat 400. The above structure is installed using the above-mentioned shear key installation method, thereby ensuring the installation effect of the shear key 600.

[0068] The main body 100 includes a first compartment 130 and a second compartment 140. The first compartment 130 is located between the first mounting plate 110 and the second mounting plate 120, and the second compartment 140 is located on the side of the first mounting plate 110 facing away from the second mounting plate 120. When the shear key 600 is installed in the above manner, after step S200, the first compartment 130 can be sealed.
