Technical Field

[0001] The invention relates to the technical field of mechanical equipment assembly, in particular to a high-precision auxiliary alignment mechanism for disassembling, assembling and resetting large or heavy machinery. Background Art

[0002] As we all know, in the repair and assembly process of heavy machinery shaft parts, after the maintenance work is completed, resetting larger shaft parts or cylindrical parts and achieving the assembly accuracy requirements of the original design has always been a pain point in the industry. In order to meet this challenge, modern industry continues to explore and innovate, striving to find more efficient and accurate solutions. A high-precision auxiliary alignment mechanism technology enables maintenance personnel to quickly locate problems and perform precise repairs, greatly improving maintenance efficiency and assembly accuracy.

[0003] At present, the commonly used positioning mechanisms mostly use various positioning mechanisms such as pins and V-blocks. However, for components with larger diameters and longer lengths, it is more difficult to ensure the coaxiality of the workpiece during processing or assembly, and the disadvantage of low precision limits the working conditions of the positioning mechanism. At the same time, it is also difficult to restore the original assembly accuracy during maintenance and assembly. High error requirements are required to ensure the assembly tracking accuracy under special working conditions.

[0004] In view of this, the designer conducted research and improvement on the existing positioning mechanism, and this case was created to suit larger diameters, longer lengths, and higher assembly precision. Summary of the invention

[0005] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide a high-precision auxiliary alignment mechanism which is simple in structure, practical, stable, reliable and efficient and can meet the design precision requirements of parts assembly.

[0006] The specific plan is as follows:

[0007] A high-precision auxiliary alignment mechanism comprises a frame, a plurality of positioning blocks are arranged above the frame, a plurality of bracket components are arranged at the bottom of the frame, and the four corners of the frame are connected with movable and height-adjustable alignment components.

[0008] The alignment mechanism comprises a clamping plate assembly fixed on the frame, the end of the clamping plate assembly is connected to the telescopic rod assembly, and the bottom of the telescopic rod assembly is connected to the sliding plate assembly.

[0009] The sliding plate assembly comprises a sliding plate, and a universal ball is arranged at the bottom of the sliding plate. The sliding plate is a triangular sliding plate, and three universal balls are evenly arranged at the bottom of the sliding plate.

[0010] The telescopic rod assembly comprises a screw tube which is threadedly connected to the clamping plate assembly, the bottom of the screw tube is connected to the slide plate through a universal joint bearing, and a hand wheel is arranged on the top of the screw tube.

[0011] The clamping plate assembly comprises an upper clamping plate and a lower clamping plate, which are fixed on the frame by bolts; the screw tube is threadedly connected with the lower clamping plate; a screw rod with scale is sleeved in the screw tube, and the top of the screw rod is fixed on the upper clamping plate.

[0012] The support assembly comprises a support fixed to the side of the frame, a foot cup is arranged in the support, and a hand wheel is arranged on the top of the foot cup.

[0013] The bottom of the frame is provided with universal wheels, which can facilitate the movement of the integrated equipment.

[0014] The positioning block is an inclined positioning block.

[0015] The mechanism of the present invention is moved to the bottom of the shaft part or the round cylinder part that needs to be positioned, the telescopic rod assembly is started, the screw tube is rotated by the hand wheel to make the sliding plate assembly contact the flat ground, the screw tube is continued to be rotated to lift the entire frame, and the telescopic rod assembly connected to the four corners of the frame is adjusted so that multiple groups of inclined surface positioning blocks fit the parts. At the same time, due to the three universal balls at the three coplanar points of the bottom of the slide plate and the universal joint bearing at the bottom of the screw tube, the position of the sliding plate assembly is automatically fine-tuned and automatically aligned; after the final alignment position is reached and multiple groups of inclined surface positioning blocks are completely fitted to the parts, the foot cup of the bracket assembly is started to finally position and limit the entire mechanism, and the fitting accuracy of the mechanism and the shaft part or the round cylinder part is guaranteed. In the subsequent disassembly and restoration and assembly process of the shaft part or the round cylinder part, no part displacement phenomenon occurs, thereby ensuring the assembly accuracy.
