In other cases, well-known structures, methods, implementations or operations are not shown or described in detail to avoid obscuring various aspects of the present disclosure.

[0026] Example 1

[0027] The utility model provides Figure 1-Figure 5 The positioning structure of a hydraulic torque converter shown in the figure comprises a mounting platform 1, a base 2, an outward expansion positioning component 3 and an inner clamp positioning component 4.

[0028] The mounting platform 1 is used to be connected to the processing table by utilizing the detachable characteristics of bolt fasteners.

[0029] The base 2 is used to be assembled with the mounting platform 1 to allow the entire outward expansion positioning assembly 3 and the inner clamp positioning assembly 4 to deviate from the horizontal plane, so as to facilitate the user to widen the processing field of view and improve the welding efficiency of the blades on the outward expansion positioning assembly 3.

[0030] Preferably, a through hole is obliquely opened in the installation platform 1, and a through column is fixed on the base 2, and the through column is inserted into the through hole. The oblique position of the installation platform 1 installed in this way is relatively fixed and only depends on the angle of the through hole.

[0031] Preferably, a spherical hole is obliquely opened in the mounting platform 1, a spherical head is fixed on the base 2, the spherical head is movably placed in the spherical hole, and a friction damping is provided between the contact surfaces of the spherical hole and the spherical groove. By utilizing the rotation characteristics between the spherical head and the spherical groove, the outward expansion positioning assembly 3 and the inner clamp positioning assembly 4 can be swung within a range, thereby improving the variability of the turbine position on the outward expansion positioning assembly 3. Furthermore, in order to improve the overall stability of the outward expansion positioning assembly 3 and the inner clamp positioning assembly 4, a limiting hole is fixed on the mounting platform 1, and a plug rod is fixed on the peripheral side of the base 2. The plug rod is inserted into the limiting hole. The shape of the plug rod is arc-shaped, and the center of curvature of the plug rod coincides with the center of curvature of the spherical groove. When adjusting, the plug rod can be pulled out and the base 2 can be rotated. When fixing, the plug rod can be inserted into the limiting hole of the mounting platform 1.

[0032] Example 2

[0033] like Figure 1-Figure 5 On the basis of the first embodiment, the external expansion positioning assembly 3 comprises a sleeve 31, a rotating rod 32, a threaded block 33 and an external expansion pin 34. The sleeve 31 passes through the central hole of the turbine. The sleeve 31 is provided with a rotating rod 32. The rotating rod 32 is fixed with a threaded block 33 which is threadedly connected to the inner wall of the sleeve 31. The end of the rotating rod 32 is provided with a wedge-shaped surface. The side wall of the sleeve 31 is elastically slidably connected with a plurality of external expansion pins 34 along the radial direction. The inner end of the external expansion pin 34 is provided with a wedge-shaped surface. The inner end of the external expansion pin 34 is located on the moving path of the end of the rotating rod 32. When in use, the user can drive the rotating rod 32 to rotate and move the rotating rod 32 along the axial direction of the sleeve 31 by screwing the rotating rod 32. When the rotating rod 32 moves downward, its wedge-shaped surface will squeeze the plurality of external expansion pins 34 located in the radial direction of the sleeve 31, and make the external expansion pins 34 extend synchronously to squeeze the central hole of the turbine, so as to realize the positioning and clamping of the inner ring body of the turbine.

[0034] Example 3

[0035] like Figure 1-Figure 5 On the basis of the first and second embodiments, the inner clamp positioning assembly 4 comprises a transmission rod 41, a threaded disc 42 and an inner clamp block 43. The end of the rotating rod 32 is fixedly connected to the transmission rod 41. The transmission rod 41 is provided with a threaded disc 42 on the outer sliding sleeve. The threaded disc 42 rotates synchronously with the rotating rod 32. The end surface of the threaded disc 42 is provided with a thread. The base 2 is slidably connected with a plurality of inner clamp blocks 43. The end surface of the inner clamp blocks 43 is also provided with a thread. The inner clamp blocks 43 and the threaded disc 42 are threadedly connected. The threaded disc 42 rotates synchronously with the rotating rod 32. The rotation of the rotating rod 32 can drive the related inner clamp blocks 43 to move outward or inward synchronously. In the specific operation, the user only needs to rotate the rotating rod 32, that is, the plurality of outer expansion pins 34 can be synchronously driven to extend outward and the inner clamp blocks 43 can be clamped inward. In this way, the purpose of synchronously clamping the inner ring body and the outer ring body of the turbine can be achieved, so that the user can improve the stability of the blade welding.

[0036] Example 4

[0037] like Figure 1-Figure 5 On the basis of Example 1 and Example 2, the inner clamp positioning assembly 4 includes a pipeline, an input block, an output block and an inner clamp block 43. The pipeline is installed on the base 2. One end of the pipeline is elastically and tightly connected to the input block and the other end is tightly connected to the output end. The pipeline is filled with a medium, such as hydraulic oil. The input block is located on the moving path of the rotating rod 32. The inner clamp block 43 is fixedly connected to the output block. When the input block is pressurized, the output block will push the inner clamp block 43 to slide along the base 2 while clamping the outer ring body through the transmission of force by the medium.

[0038] Example 5

[0039] like Figure 1-Figure 5 On the basis of the above embodiment, a plurality of slide grooves are provided on the side wall of the sleeve 31, each of which is slidably connected with a V-shaped elastic sheet 5, and the V-shaped elastic sheet 5 is located in the middle hole of the workpiece. The elasticity of the V-shaped elastic sheet 5 can be pre-clamped in the middle hole of the inner ring body before the outer expansion nail 34 clamps the inner ring body, so that the user can further adjust the position of the inner ring body and the outer ring body.

[0040] Preferably, the outwardly expanded nails 34 and the V-shaped elastic sheets 5 are arranged alternately, and the outwardly expanded nails 34 and the V-shaped elastic sheets 5 do not interfere with each other. This has the advantages of having more clamping points and high stability.

[0041] Preferably, the outward expansion pins 34 and the corresponding V-shaped elastic sheets 5 are arranged in the same direction, so as to reduce the clamping points and reduce the probability of the high-precision inner ring body being worn by the clamp.

[0042] In summary, the main technical solution of the present application is to utilize the driving action of the rotating rod 32 to synchronously control the outer expansion pins 34 to extend outward to clamp the inner ring body, and the inner clamp block 43 to clamp the outer ring body inward, so as to simultaneously determine the positional relationship between the inner and outer ring bodies, thereby improving the accuracy of welding blades on the inner and outer ring bodies by later users.

[0043] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model should be included in the protection scope of the present utility model.
