[0026] To make the technical means, creative features, achieved objectives and functions of this utility model clearer and easier to understand, the utility model will be further described below with reference to the accompanying drawings and specific embodiments:

[0027] like Figures 1 to 2 As shown, this utility model proposes an automatic tube sheet alignment device, including: a base frame 1, an X-direction pushing mechanism 2, a Y-direction pushing mechanism 3, a guiding mechanism 4, and a positioning frame 5. The base frame 1 is used to support the tube sheet. One end of the base frame 1 in the X direction is the X-direction feeding end 11, and the opposite end of the X-direction feeding end 11 is the X-direction positioning end 12. One end of the base frame 1 in the Y direction is the Y-direction feeding end 13, and the opposite end of the Y-direction feeding end 13 is the Y-direction positioning end 14. The X-direction pushing mechanism 2 is installed at the center of the X-direction feeding end 11 of the base frame 1. The X-direction pushing mechanism 2 is used to push the tube sheet along the X direction to the X-direction positioning end 12; the Y-direction pushing mechanism 3 is installed on the Y-direction feeding end 13 of the base frame 1, and is used to push the tube sheet along the Y direction to the Y-direction positioning end 14; the positioning frame 5 includes: an X-direction blocking frame 51 and a Y-direction blocking frame 52, the X-direction blocking frame 51 is installed on the X-direction positioning end 12 of the base frame 1, and the Y-direction blocking frame 52 is installed on the Y-direction positioning end 14 of the base frame 1, with the X-direction blocking frame 51 and the Y-direction blocking frame 52 forming a 90-degree angle. The tube sheet is supported by the base frame 1, and the X-direction and Y-direction pushing mechanisms are used to push the tube sheet to its respective positioning end along the X and Y directions of the base frame 1, respectively. The X-direction pushing mechanism 2 consists of a first push plate 21, a first sliding seat 22, a first slide rail 23, and a first cylinder 24, all installed at the center of the X-direction feeding end 11 of the base frame 1. These components work together to move the tube sheet along the X-axis to the positioning end. The Y-direction pushing mechanism 3 consists of a pushing assembly 31, a second slide rail 32, and a second cylinder 33, responsible for moving the tube sheet along the Y-axis to the positioning end. The positioning frame 5 consists of an X-direction blocking frame 51 and a Y-direction blocking frame 52, set at 90-degree angles at both ends of the base frame 1 to ensure precise alignment of the tube sheet in both vertical directions. The guiding mechanism 4 includes a conveying roller 41 and a support plate 42, evenly distributed on the base frame 1, providing sliding guidance for the tube sheet. The entire device achieves automated tube sheet alignment through the precise control and coordinated actions of these mechanisms.

[0028] The guide mechanism 4 is mounted on the base frame 1 and is evenly distributed along the X direction of the base frame 1. The guide mechanism 4 is used to support the tube sheet and allow the tube sheet to slide along the X direction of the base frame 1. The base frame 1 supports the tube sheet through the guide mechanism 4. The guide mechanism 4 is evenly distributed along the X direction of the base frame 1 and consists of a conveying roller 41 and a support plate 42. It is used to support the tube sheet and guide it to slide along the X direction, ensuring smooth movement of the tube sheet and reducing friction to achieve precise alignment.

[0029] The Y-direction pushing mechanism 3 includes a pushing component 31, a second slide rail 32, and a second cylinder 33. The pushing component 31 is installed on the Y-direction feeding end 13, and the second slide rail 32 is installed on the base frame 1 and is located in the Y direction. The pushing component 31 is slidably connected to the second slide rail 32. The output end of the second cylinder 33 is connected to the pushing component 31, and the second cylinder 33 is used to pull the pushing component 31 to slide along the second slide rail 32. Driven by the second cylinder 33, the Y-direction pushing mechanism 3 causes the pushing component 31 to slide along the second slide rail 32 in the Y direction, thereby pushing the tube sheet from the feeding end to the positioning end.

[0030] The push assembly 31 is equipped with a push actuator, which can rotate relative to the output end of the second cylinder 33. The push actuator is in the vertical position when it is in the vertical direction, and in the deflection position when it is near the Y-direction positioning end 14. When the push actuator is in the deflection position, it deflects to a position parallel to the Y-direction. The push actuator can only rotate between the vertical position and the deflection position. The push actuator in the push assembly 31 can rotate relative to the output end of the second cylinder 33 to switch between the vertical and deflection positions. When feeding is required, the push actuator is in the deflection position; when pushing the tube sheet is required, the push actuator is in the vertical position.

[0031] The pushing component 31 includes a second push plate 311 and a second sliding seat 312. The second push plate 311 is the pushing execution end of the pushing component 31. The second push plate 311 is rotatably mounted on the second sliding seat 312. The second sliding seat 312 is slidably mounted on the second guide rail. The second sliding seat 312 is connected to the output end of the second cylinder 33. An elastic element is installed at the connection between the second push plate 311 and the second sliding seat 312.

[0032] The second push plate 311 includes a top plate 3111 and a rotating arm 3112. The top plate 3111 is located above the second sliding seat 312 and is used to push the tube sheet. The rotating arm 3112 is connected to the side of the top plate 3111 away from the Y-direction positioning end 14. The rotating arm 3112 is hinged to the second sliding seat 312. An elastic plate is connected between the rotating arm 3112 and the second sliding seat 312. The elastic plate is used to keep the top plate 3111 on the rotating arm 3112 in a vertical position. The pushing assembly 31 directly pushes the tube sheet through the top plate 3111 of the second push plate 311. The top plate 3111 is hinged to the second sliding seat 312 through the rotating arm 3112 and can rotate between vertical and deflection positions to adapt to the tube sheet alignment requirements. The elastic plate ensures that the top plate 3111 maintains a stable vertical position during the pushing process. The entire assembly is driven by the second cylinder 33 to slide along the second guide rail, realizing the precise pushing and positioning of the tube sheet in the Y direction.

[0033] The top plate 3111 has a square hole in the middle, and a guide wheel 3113 is installed in the square hole. The guide wheel 3113 is used to keep in close contact with the tube sheet. The guide wheel 3113 installed in the square hole in the middle of the top plate 3111 is in close contact with the tube sheet to ensure that the tube sheet moves smoothly along the predetermined path during the pushing process, reducing friction and deviation.

[0034] The X-direction pushing mechanism 2 includes a first push plate 21, a first sliding seat 22, a first slide rail 23, and a first cylinder 24. The first push plate 21 is located at the X-direction feeding end 11. The first sliding seat 22 is connected below the first push plate 21. The first sliding seat 22 is slidably connected to the first slide rail 23. The first slide rail 23 is mounted on the base frame 1 and is located in the X-direction. The first cylinder 24 is on the base frame 1, and the output end of the first cylinder 24 is connected to the first push plate 21 or the first sliding seat 22. The first cylinder 24 is used to pull the first push plate 21 to slide along the first slide rail 23. By connecting the output end of the first cylinder 24 to the first push plate 21 or the first sliding seat 22 below it, the extension and retraction of the cylinder drives the first push plate 21 to slide along the first slide rail 23 in the X-direction mounted on the base frame 1, thereby accurately pushing the tube sheet from the X-direction feeding end to the positioning end.

[0035] The guiding mechanism 4 includes: conveying rollers 41 and support plates 42. There are four support plates 42, with a row of conveying rollers 41 positioned between every two support plates 42. The conveying rollers 41 are parallel to the X-direction, and their ends are hinged to the support plates 42. The guiding mechanism 4 is evenly distributed on the base frame 1 via four support plates 42. A row of conveying rollers 41 parallel to the X-direction is installed between each pair of support plates 42. These rollers are hinged to the support plates 42 at both ends, allowing the tube sheet to slide smoothly on the rollers, reducing friction, and maintaining stable movement of the tube sheet in the X-direction.

[0036] The intersection of the X-direction blocking frame 51 and the Y-direction blocking frame 52 serves as the centering reference angle. A detector 6 is located near the centering reference angle on the X-direction blocking plate, used to detect whether the tube sheet has been pushed into position. Several rotatable pulleys 511 are installed on both the X-direction blocking frame 51 and the Y-direction blocking frame 52. The pulleys 511 on the X-direction blocking frame 51 are spaced apart from the conveyor roller 41, and are evenly distributed on both frames. The rotatable pulleys 511 installed on the X-direction blocking frame 51 and the Y-direction blocking frame 52, spaced apart from the conveyor roller 41 and evenly distributed on the two blocking frames, reduce friction and wear during tube sheet movement. The rotation of the pulleys 511 further ensures the smoothness and flexibility of tube sheet movement. Simultaneously, the even distribution of the pulleys 511 helps to distribute the weight of the tube sheet, maintaining its stability during centering and positioning.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
