It should be understood that a person of ordinary skill in the art can recognize that the present invention can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details to obscure the description of the present invention. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles and features disclosed in the present application.

[0019] Example 1 In order to solve the defects of low assembly efficiency, easy damage and poor generality of large-scale shaft sleeve parts in the prior art, this embodiment provides a flexible assembly tool for large-scale shaft sleeve parts, see Figure 1 , Figure 2 , specifically comprising a first displacement assembly 1, and a second displacement assembly 2 and a fixture 3 arranged in the first displacement assembly 1, wherein the second displacement assembly 2 is slidably connected to the first displacement assembly 1, and the fixture 3 is arranged on the second displacement assembly 2 to realize the movement of the workpiece 4 clamped on the fixture 3 in three directions of X, Y and Z axes; A rotating support 31 is disposed at the bottom of the fixture 3 for carrying the workpiece 4 and rotating the workpiece 4 at an angle.

[0020] See also Figure 4 , Figure 8During operation, the rotating support member 31 is used to support the workpiece 4 and can rotate. The rotation of the rotating support member 31 can realize the rotation of the workpiece 4, thereby improving the stability of the workpiece 4. At this time, the rotating support member 31 includes a flexible pad 311, a bearing plate 312, a rotating plate 313, a connecting member 314, a thrust ball bearing 315, and a deep groove ball bearing 316 connected in sequence from top to bottom. The flexible pad 311, the bearing plate 312, and the rotating plate 313 are connected by the connecting member 314. Then, the longitudinal section of the rotating disk 313 is T-shaped, and the vertical sides of the T-shape extend into the thrust ball bearing 315 and the deep groove ball bearing 316 in sequence, so that the rotating disk 313 and the thrust ball bearing 315 and the deep groove ball bearing 316 are connected in an axial rotation, that is, when the rotating disk 313 and the supporting disk 312 are rotated, the workpiece 4 on the flexible pad 311 rotates accordingly to drive the thrust ball bearing 315 and the deep groove ball bearing 316 to rotate in the axial direction. It can be explained that the lower bottom surface of the T-shaped horizontal side is adaptively connected with the upper end surface of the thrust ball bearing 315, and the thrust ball bearing 315 forms a transition fit through the rotating disk 313 and the fixing ring 317 to achieve rotation and upward support;, as Figure 8 The fixing ring 317 and the thrust ball bearing 315 are both located at the lower part of the rotating disk 313 , and the thrust ball bearing 315 is located inside the fixing ring 317 and at the lower part of the rotating disk 313 .

[0021] The bottom of the clamp 3 is provided with a mounting hole 32 for fitting the deep groove ball bearing 316, and the vertical side of the T-shaped is inserted into the mounting hole 32; for example, two deep groove ball bearings 316 are arranged in the mounting hole 32, and are arranged at intervals, and the deep groove ball bearing 316, the thrust ball bearing 315, and the mounting hole 32 are coaxially arranged; Furthermore, in order to improve stability, the flexible pad 311 , the carrying plate 312 , and the rotating plate 313 are coaxially arranged.

[0022] For example, the connecting member 314 includes a screw 314a and at least three nuts 314b adapted to connect with the screw 314a. When there are three nuts 314b, two nuts 314b are located between the bearing plate 312 and the rotating plate 313 to prevent the workpiece 4 from being deflected during assembly, so as to ensure that the workpiece 4 is perpendicular to the horizontal plane in the axial direction. The other nut 314b is located on the upper end surface of the bearing plate 312. At this time, the rotating plate 313 is provided with three concave sections along its circumferential direction, so that the nut 314b is exposed in the concave sections. In order to reduce costs and reduce the weight of the tool, the rotating plate 313 and the bearing plate 312 are both structures with a central hole in the middle.

[0023] In order to accurately rotate the angle, for example, an angle sensor can be installed on the rotating support 31 so that the angle adjustment accuracy reaches ±0.1°, ensuring that the keyway or other positioning features of the shaft and the workpiece 4 are accurately aligned during the assembly process; to avoid damage to the surface of the workpiece 4, the flexible pad 311 is a flexible wear-resistant material, such as polyurethane rubber, which forms a soft contact with the workpiece to avoid bumps and scratches.

[0024] The arrangement of the rotating support 31 on the fixture 3 can realize the rotation of the rotating workpiece 4 in the horizontal direction and adjust its horizontal placement angle.

[0025] In the specific implementation process, see Figure 6 , Figure 7 The first displacement assembly 1 includes a sliding frame 11, a first slider 12, and a lift 13. A first slide rail 111 slidably connected to the first slider 12 is provided on the inner side wall of the sliding frame 11 along its height direction; The elevator 13 is provided with two and symmetrically arranged on both sides of the sliding frame 11. The screw nut on the elevator 13 is fixedly connected to the second displacement assembly 2. The side of the first slider 12 facing away from the first slide rail 111 is fixedly connected to the second displacement assembly 2. The elevator 13 drives the second displacement assembly 2 to slide along the first slide rail 111 in the Z-axis direction. The screw on the elevator 13 is parallel to the height direction of the sliding frame 11, and its top is fixed to the crossbeam at the top of the sliding frame 11 through the first fixing plate 14. For the convenience of lifting, a lifting lug 15 can be provided on the crossbeam at the top of the sliding frame 11; For example, a caster 112 with a brake is provided at the bottom of the sliding frame 11, which is convenient for sliding the assembly tool to the tooling position, which is convenient, labor-saving, and easy to carry. In addition, it can be fixed at a desired position; in order to reduce the weight while having a certain strength to carry the first displacement component 1, the fixture 3 and the workpiece 4, the bottom of the sliding frame 11 is provided with at least three first transverse plates 113 arranged at intervals along its width direction, and at least one second transverse plate 114 is provided along its length direction, and the second transverse plate 114 is provided in the middle of the bottom, and the lift 13 is provided on the second transverse plate 11 4; the sliding frame 11 includes at least four first vertical plates 115, which are used to vertically connect the bottom of the sliding frame 11, and the first slide rails 111 are arranged on the inner side walls of the first vertical plates 115, for example, there are four first vertical plates 115. At this time, the bottom of the sliding frame 11 is rectangular or square, and the four first vertical plates 115 are respectively vertically connected to the upper end surface of the bottom. At this time, the second displacement component 2 is slidably connected along the height direction of the sliding frame 11, that is, the second displacement component 2 is arranged parallel to the bottom of the sliding frame 11.

[0026] Furthermore, in order to realize automation and save time and effort, the first displacement assembly 1 further includes a reduction motor 16 and a transmission shaft 17. The two sides of the reduction motor 16 are respectively connected to the two elevators 13 through the transmission shaft 17, and the two elevators 13 are simultaneously controlled to open through the reduction motor 16. At the same time, the displacement and speed of the second displacement assembly 2 in the Z-axis direction can be controlled by controlling the rotation speed of the reduction motor 16.

[0027] In order to adapt to different scenarios, avoid emergencies such as power failure, and fine-tune the displacement, the first displacement assembly 1 also includes a first hand wheel 18 connected to the elevator 13, and the elevator 13 is controlled to open by rotating the first hand wheel 18. For example, the elevator 13 is a trapezoidal screw.

[0028] In the specific implementation process, see Figure 3-Figure 5 , Figure 7 The second displacement assembly 2 includes a Z-axis moving base 21, an X-axis moving base 22, and a Y-axis moving base 23 which are slidably connected in sequence from bottom to top, and the four corners of the Z-axis moving base 21 are respectively fixedly connected with a first slider 12, and the second slide rails 211 are provided along the length direction of both sides of the upper part of the Z-axis moving base 21; A second slide block 221 slidably adapted to the second slide rail 211 is provided along the length direction of both sides of the lower portion of the X-axis movable base 22, and a third slide rail 222 is provided along the width direction of both sides of the upper portion of the X-axis movable base 22; The lower part of the Y-axis movable base 23 is provided with a third slider 231 slidably matched with the third slide rail 222, and the upper part is connected with the clamp 3 to realize the movement of the workpiece 4 clamped in the clamp 3 in the three directions of X, Y and Z axes.

[0029] In order to reduce the weight of the assembly tool, the Z-axis movable base 21, the X-axis movable base 22, and the Y-axis movable base 23 are all frame structures arranged parallel to the bottom of the sliding frame 11; Further, the second displacement assembly 2 further includes a first transmission element 24, a second transmission element 25, a second hand wheel 26, and a third hand wheel 27. One side of the first transmission element 24 is connected to the second hand wheel 26, and the other side is connected to the X-axis movable base 22. The movement of the X-axis movable base 22 in the X-axis direction is controlled by the second hand wheel 26, that is, the X-axis movable base 22 slides along the second slide rail 211 by rotating the second hand wheel 26. One side of the second transmission element 25 is connected to the third hand wheel 27 and the other side is connected to the Y-axis movable base 23. The movement of the Y-axis movable base 23 in the Y-axis direction is controlled by the third hand wheel 27, that is, the Y-axis movable base 23 slides along the third slide rail 222 by rotating the third hand wheel 27.

[0030] For example, the first transmission element 24 and the second transmission element 25 are both ball screws. For example, one end of the screw in the second transmission element 25 is connected to the third hand wheel 27, and the other end passes through the fixed end screw support 251 and the supporting end screw support 252 in sequence (the nut on the second transmission element 25 is located on its screw), and the two ends of the screw are respectively supported by the fixed end screw support 251 and the supporting end screw support 252, and the upper part of the nut in the second transmission element 25 is fixedly connected to the bottom of the Y-axis movable base 23. By rotating the third hand wheel 27, the nut in the second transmission element 25 drives the Y-axis movable base 23 to move along the length direction of the screw in the second transmission element 25, and then the third hand wheel 27 is rotated to make the Y-axis movable base 23 slide along the third slide rail 222. It can be explained that the second transmission element 25 has the same structure and movement principle as the first transmission element 24 , except that the first transmission element 24 controls the movement of the X-axis movable base 22 in the X-axis direction, and therefore, the structural connection positions thereof are different.

[0031] The second hand wheel 26 and the third hand wheel 27 can be used to achieve fine adjustment of the workpiece 4 in the X-axis and Y-axis directions, which is convenient for centering during the assembly process.

[0032] In the specific implementation process, see Figure 3 The clamp 3 includes a fixed frame 33, a third transmission element 34, and a clamp body 35. The bottom of the fixed frame 33 is fixedly connected to the upper end surface of the Y-axis movable base 23. The rotating support member 31 is arranged at the bottom of the fixed frame 33 to support and rotate the workpiece 4. The third transmission element 34 is symmetrically arranged on the two side walls of the upper part of the fixed frame 33. The clamp body 35 is fixed to a side of the third transmission element 34 facing the center of the fixed frame 33. The clamp body 35 is controlled by the third transmission element 34 to approach or move away from the center of the fixed frame 33, so as to realize the clamping or releasing of the workpiece 4 in the fixed frame 33 by the clamp 3.

[0033] That is, the workpiece 4 is placed in the fixed frame 33, and is supported and rotated by the fixed frame 33; to facilitate the installation of the workpiece 4, the fixed frame 33 has a quadrilateral bottom, and the two longitudinal cross-sections of the fixed frame 33 are U-shaped, and the two third transmission elements 34 are respectively arranged at the top where the two vertical sides of the U-shape are located, so as to clamp the workpiece 4 in the middle of the U-shape; for example, the bottom of the fixed frame 33 is a rectangular frame structure, and in the longitudinal direction there are two symmetrically arranged rectangular or square frame structures, so that the rectangular or square frame structure is perpendicular to the frame structure at the bottom of the fixed frame 33, and further, in order to prevent the workpiece 4 from falling, the two frame structures in the longitudinal direction can be connected by a connecting beam 36, and the setting height of the connecting beam 36 is preferably two-thirds of the height of the frame structure in the longitudinal direction. It can be explained that the installation position cannot be lower than half the height of the frame structure in the longitudinal direction.

[0034] It can be seen that the clamp 3 can achieve radial stability of the tool to avoid tipping.

[0035] Further, see Figure 3 The fixture 3 further includes a fixing seat 37 and a guide member 38 connected to the third transmission element 34. The fixing seat 37 is fixed to the upper portion of the fixing frame 33 to connect the third transmission element 34. One end of the guide member 38 is inserted into the clamp body 35 and the other end is fixed to the fixing seat 37 , so that the clamp body 35 slides along the length direction of the guide member 38 to achieve the clamping or releasing of the workpiece 4 in the fixing frame 33 by the clamp 3 .

[0036] For example, the third transmission element 34 is a trapezoidal screw, that is, one end of the screw in the third transmission element 34 is fixedly connected to the clamp body 35, and the nut in the third transmission element 34 is arranged on the fixed seat 37. When the third transmission element 34 is working, the nut therein is fixed, and the screw moves along the axial direction, thereby driving the clamp body 35 to move along the axial direction of the screw to realize the clamping and loosening of the workpiece 4.

[0037] Furthermore, the clamp 3 also includes a fourth hand wheel 39 connected to the third transmission element 34, and the third transmission element 34 is opened by controlling the rotation of the fourth hand wheel 39, that is, the fourth hand wheel 39 is connected to the screw rod in the third transmission element 34. It can be seen that one end of the screw rod is connected to the fourth hand wheel 39 and the other end is connected to the clamp body 35.

[0038] In order to adapt to different types of workpieces 4, such as workpieces 4 with different outer diameters, the cross-section of the clamp body 35 is constructed as a > shape, which is used to clamp different types of workpieces 4. It can be seen that the opening angle of the > shape and the length of the side determine how many types of workpieces 4 the same clamp body 35 can clamp.

[0039] The present invention is achieved in that: 1. Place the workpiece 4 on the rotating support 31 in the fixture 3; 2. The height of the workpiece 4 is adjusted by the first displacement assembly 1; and then the displacement of the workpiece 4 in the X-axis and Y-axis directions is adjusted by the second displacement assembly 2, so as to finally achieve the coaxiality and axial positioning of the workpiece 4 and the sleeve; 3. The rotating support 31 is rotated to realize the assembly connection between the tool and the special structure inside the sleeve.

[0040] The flexible assembly tool structure designed in the present invention can efficiently, accurately and safely complete the assembly of large-scale shaft sleeve workpieces, such as blade assembly.

[0041] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention.

[0043] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
