The first screw connects the main body and the sleeve seat, and the second screw connects the shear key and the sleeve, thereby enabling the shear key to be installed on the main body. Since the first and second screws share the same sleeve seat, there is a clearance requirement between the ends of the first and second screws within the sleeve seat to prevent interference that could affect the installation of the second screw, thus preventing the shear key from being installed. Summary of the Invention

[0006] S100, the main body includes a first mounting plate and a second mounting plate, a first screw connects the first mounting plate and the sleeve seat, and the first screw is screwed into the sleeve seat a first preset distance;

[0007] S200, the base is welded to the sleeve seat and the second mounting plate respectively, the sleeve seat is disposed between the first mounting plate and the base, and the distance between the first side of the base away from the first mounting plate and the first end face of the first screw in the sleeve seat is a second preset distance;

[0008] S300, the second screw connects the shear key and the sleeve seat from the side away from the first mounting plate.

[0009] In some possible implementations, the base has a recessed groove and a connecting hole arranged along the center line, the sleeve seat is disposed in the recessed groove, and the second screw passes through the connecting hole and the sleeve seat to connect with the sleeve seat; in step S200, the method further includes: S210, adjusting the depth of the sleeve seat in the recessed groove so that the distance between the first side and the first end face of the first screw is the second preset distance, and then welding the second mounting plate to the base.

[0010] In some possible implementations, after step S200, the method further includes: step S220, detecting whether the flatness of the first side surface is a preset value.

[0011] If yes, proceed to step S300; and / or,

[0012] If not, then the first side of the base is corrected until the flatness of the first side reaches a preset value.

[0013] In some possible implementations, step S220 further includes: coloring the first side surface with red lead on the brush block, and correcting its flatness by polishing the first side surface.

[0014] In some possible implementations, the base has a groove, the shear key has a boss, the boss is located in the groove, the height of the boss is greater than the depth of the groove, and the boss and the groove are in clearance fit; the roughness of the peripheral side surface of the boss and the groove sidewall is the same, and both are less than the roughness of the top surface of the boss and the roughness of the bottom wall of the groove; the fitting block includes a flat plate and a limiting block disposed on the flat plate, the shape, size and roughness of the limiting block and the boss are the same, the flat plate can cover the first side surface, and the flatness of the flat plate is not greater than the flatness of the first side surface; step S220 further includes: the limiting block is limited to the groove, and the first side surface is colored with red lead on the flat plate.

[0015] In some possible implementations, the brush block includes at least two gripping structures disposed on the side of the plate opposite to the limiting block.

[0016] In some possible implementations, the fitting block includes a reinforcing rib disposed on the side of the flat plate opposite to the limiting block, and the fitting block is made of aluminum.

By controlling the first screw's insertion distance into the sleeve seat by a first preset distance, the accuracy of the first screw's distance within the sleeve seat is improved. Since the first side is used to closely mate with the shear key's end face, by controlling the second preset distance between the first side and the first end face using the first side as a reference, the accuracy of the relative installation position of the sleeve seat and the base is improved. This, in turn, improves the fitting accuracy between the sleeve seat and the second screw, enhances the length accuracy of the second screw's insertion into the sleeve seat, and ensures that the ends of the first and second screws meet the clearance requirements within the sleeve seat, preventing interference that could affect the installation of the second screw and guaranteeing the shear key can be installed.

[0039] To make the technical problems solved by the present invention, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0041] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature.

[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 connected to the sleeve seat 400 via 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 base 500 are welded to sleeve seat 400 and second mounting plate 120 respectively. Sleeve seat 400 is located between first mounting plate 110 and base 500. The distance between the first side 530 of base 500 away from first mounting plate 110 and the first end face 210 of first screw 200 in sleeve seat 400 is the second preset distance B.

[0045] S300 and the second screw 300 are connected to the shear key 600 and the sleeve seat 400 from the side away from the first mounting plate 110.

[0046] By controlling the first screw 200 to screw into the sleeve seat 400 at a first preset distance A, the accuracy of the first screw 200's distance from the sleeve seat 400 within the preset distance is improved. Since the first side surface 530 is used to closely engage with the end face of the shear key 600, by using the first side surface 530 as a reference and controlling the second preset distance B between the first side surface 530 and the first end face 210, the accuracy of the relative installation position of the sleeve seat 400 and the base 500 is provided. This improves the fit accuracy between the sleeve seat 400 and the second screw 300, and enhances 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 within the sleeve seat 400 meet the clearance requirement 721, preventing interference from affecting the installation of the second screw 300 and ensuring the shear key 600 can be installed. The specific measurement methods for the first preset distance A and the second preset distance B are readily available in existing technology and will not be elaborated further.

[0047] In one embodiment, the length of the sleeve seat 400 is 185mm, the first preset distance A is 85mm, and the process proceeds after passing inspection; the second preset distance B is 120mm, and the process proceeds after passing inspection. The second screw 300 is screwed into the sleeve seat 400 by a distance of 85mm, and the distance between the ends of the first screw 200 and the second screw 300 in the sleeve seat 400 is 15mm, which meets the clearance requirement 721.

[0048] The length of the 400mm sleeve seat is a critical control point. After processing, it must be inspected and qualified before proceeding to the next process.

[0049] In step S200, the installation position of the sleeve seat 400 on the base 500 is first determined, ensuring that the distance between the first side surface 530 and the first end face 210 is the second preset distance B, and the sleeve seat 400 and the base 500 are welded; then, the base 500 is adapted to be welded to the second mounting plate 120 according to the position of the base 500.

[0050] In one embodiment, the base 500 has a recessed groove 510 and a connecting hole 520 arranged along the same center line, the sleeve seat 400 is disposed in the recessed groove 510, and the second screw 300 passes through the connecting hole 520 and the sleeve seat 400 to connect with the sleeve seat 400; in step S200, the method further includes:

[0051] S210. Adjust the depth of the sleeve seat 400 in the recess 510 so that the distance between the first side surface 530 and the first end face 210 of the first screw 200 is a second preset distance B. Then weld the second mounting plate 120 to the base 500. By setting the recess 510, it is easy to adjust the distance between the first side surface 530 and the first end face 210 to the second preset distance B, which reduces the machining accuracy requirements of the second mounting plate 120 and the sleeve seat 400, and also reduces the accuracy requirements of the first screw 200 screwing into the sleeve seat 400 at the first preset distance A. That is, it reduces the assembly requirements and thus reduces the cost.

[0052] Generally, the span between the first mounting plate 110 and the second mounting plate 120 is relatively large, resulting in the first screw 200 passing through the first mounting plate 110 and the sleeve seat 400 with a large distance between them; the second screw 300 passes through the shear key 600, the base 500, and the sleeve seat 400, passing through multiple holes. In other words, both the first screw 200 and the second screw 300 need to pass through multiple holes with long spans, requiring high structural precision. For example, the screw specification is M56*1050, but 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 main board. There are 12 mounting holes on the first mounting plate 110, the second mounting plate 120, and the shear key 600, as well as 12 countersunk grooves 510 and connecting holes 520 on the base 500, arranged in a one-to-one correspondence to connect with 12 first screws 200 and 12 second screws 300. The mounting holes, countersunk grooves 510, and connecting holes 520 on the base 500 are all concentrically arranged. After processing, the concentricity of the holes in the shear key 600, the base 500, and the first and second mounting plates 110 and 120 needs to be checked before proceeding to the next process to ensure the subsequent installation of the first screws 200 and second screws 300.

[0053] In one embodiment, the base 500 has a groove 540, and the shear key 600 has a boss 610. The boss 610 is disposed within the groove 540, and the boss 610 and the groove 540 are in a clearance fit. The height C of the boss 610 is greater than the depth D of the groove 540, ensuring that the shear key 600 and the first side surface 530 can fit tightly together. The roughness of the peripheral side surface of the boss 610 and the groove sidewall of the groove 540 is 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, the groove sidewall 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, and the inclined surface has a guiding function to facilitate the installation and disassembly of the boss 610 and the groove 540.

[0055] When machining the base 500 and shear key 600, the dimensions and roughness of the groove 540 and boss 610 must be inspected and approved before proceeding to the next process.

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

[0057] Step S220: Check whether the flatness of the first side surface 530 is the preset value, such as by using a laser flatness 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, then the first side 530 of the base 500 is corrected until the flatness of the first side 530 reaches the 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 further includes: coloring the first side surface 530 with red lead on the brush block 700, and correcting its flatness by polishing the first side surface 530.

[0061] Because the base 500 has a large cross-sectional area, such as 2000mm x 450mm, traditional molding plates are too small to meet the 1.0mm flatness requirement for large-area molding. In one embodiment, the molding block 700 includes a flat plate 710 and a limiting block 720 disposed on the flat plate 710. The limiting block 720 and the boss 610 have the same shape, size, and roughness. The flat plate 710 can cover the first side surface 530, and the flatness of the flat plate 710 is not greater than the flatness of the first side surface 530. Step S220 further includes: limiting the limiting block 720 in the groove 540, and coloring the first side surface 530 on the flat plate 710 with red lead. By increasing the area of ​​the flat plate 710 to cover the first side surface 530, the 1.0mm flatness requirement for large-area molding can be met. Based on the flatness measurement data from the laser flatness measuring instrument, the first side 530 of the base 500 is brushed with red lead dye on the flat plate 710. After the flatness of the first side 530 meets the requirement of 1.0mm, the process continues to the next step, and the corresponding shear key 600 is installed. Similarly, the calibration and installation of the other shear keys 600 are completed in sequence.

[0062] Because the plate 710 has a large cross-sectional area, the clamping block 700 includes reinforcing ribs 740 on the side of the plate 710 opposite to the limiting block 720 to improve structural strength and prevent structural deformation. Optionally, the clamping block 700 is made of aluminum, such as 2A02 hard aluminum, which ensures the strength of the entire clamping block 700. Because the plate 710 has a large structure and weight (approximately 39 kg), the clamping block 700 may optionally include at least two gripping structures 730 on the side of the plate 710 opposite to the limiting block 720, enabling at least two people to operate the clamping block 700 simultaneously.

[0063] Optionally, the reinforcing rib 740 includes transverse stiffeners 741 and longitudinal stiffeners 742, which are respectively arranged intersecting along the transverse and longitudinal directions of the flat plate 710. The number of transverse stiffeners 741 and longitudinal stiffeners 742 can be set according to requirements and is not limited.

[0064] In one embodiment, the manufacturing method of the fitting block 700 includes: cutting and manufacturing an aluminum plate 710 according to the above structure, and transferring it to another process after passing inspection. When the groove 540 and the boss 610 have inclined surfaces, the limiting block 720 of the fitting block 700 is machined to form the corresponding inclined surface. After passing inspection, it is transferred to another process and sent to a testing agency for calibration. After passing inspection, it can be used.

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

[0066] The base 500 and the second mounting plate 120 are welded using a symmetrical welding method. For example... Figure 6 As shown, by controlling the welding sequence according to ①-②, ③-④..., welding deformation can be effectively controlled, reducing the need for subsequent reprocessing of the first side 530.

[0067] This embodiment provides a vessel, 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 disposed 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, and 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-described 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, the first compartment 130 can be sealed after step S200.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
