[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1 to 3 As shown in the figure, this application embodiment provides a fixed-pitch propeller machining auxiliary support device. The auxiliary support device includes a chuck 10, a first support rod 20, a second support rod 30, an elastic element 40, a fixing clamp 50, and a base 60. The chuck 10 is used to clamp the propeller blade. The first support rod 20 is disposed at the bottom end of the chuck 10. The elastic element 40 is sleeved on the second support rod 30. The fixing clamp 50 includes at least two mounting cylinders 51 arranged side by side. The first support rod 20 and the second support rod 30 are disposed in the mounting cylinders 51. The base 60 is connected to the bottom end of the second support rod 30. The two ends of the elastic element 40 abut against the fixing clamp 50 and the base 60, respectively.

[0029] The fixing clamp 50 has a locked state and a released state. The fixing clamp 50 includes two opposing fixing plates, each with a semi-circular groove. The two semi-circular grooves combine to form a mounting cylinder 51. The two fixing plates are locked together by screws. When it is necessary to clamp the first support rod 20 and the second support rod 30, the screws are turned to fix the first support rod 20 and the second support rod 30 inside the mounting cylinder 51. When it is necessary to release, the screws are turned, and the first support rod 20 and the second support rod 30 can move relative to the fixing clamp 50.

[0030] When the first support rod 20 and the second support rod 30 are fixed, the elastic element 40 fitted on the second support rod 30 is compressed. In use, the worker loosens the locking screw of the fixing clamp 50, so that the fixing clamp 50 releases the second support rod 30. At this time, the fixing clamp 50 can slide on the second support rod 30. The fixing clamp 50 is still fixed to the first support rod 20. The preload of the elastic element 40 partially offsets the weight of the tooling, that is, partially offsets the weight of the chuck 10 and the first support rod 20. At this time, the height of the chuck 10 can be adjusted by manually pushing or pulling the upper chuck 10 or the first support rod 20.

[0031] After the height of the chuck 10 is adjusted and determined, the first support rod 20, the second support rod 30 and the elastic element 40 are completely fixed by locking the fixing clamp 50, eliminating the risk of displacement caused by the deformation of the elastic element 40, and ensuring that the tooling as a whole does not loosen during processing.

[0032] During installation, the position of the fixing clamp 50 on the second support rod 30 can be changed to pre-tighten the elastic element 40.

[0033] In one embodiment, a sleeve slider 70 is also sleeved on the first support rod 20. The sleeve slider 70 can slide on the first support rod 20. The sleeve slider 70 is sleeved on the first support rod 20 and fixedly connected to the second support rod 30. The sleeve slider 70 has an installation cavity inside for the first support rod 20 to pass through. The sleeve slider 70 can also lock or loosen the first support rod 20, and can be adjusted according to the usage requirements.

[0034] Furthermore, the sleeve slider 70 includes a slider body 71 and a fixing seat 72. The mounting cavity is located inside the slider body 71. The first support rod 20 passes through the inside of the slider body 71. An adjusting rod 73 is provided on the slider body 71. The adjusting rod 73 is threadedly connected to the slider body 71. The adjusting rod 73 can abut against the first support rod 20 inside the mounting cavity. When it is necessary to fix the first support rod 20, the adjusting rod 73 is rotated to abut against the first support rod 20. When it is necessary for the slider body 71 to slide relative to the first support rod 20, the adjusting rod 73 is rotated to separate the adjusting rod 73 from the first support rod 20. The fixing seat 72 is fixedly connected to the slider body 71. An mounting groove is provided inside the fixing seat 72. The second support rod 30 is located in the mounting groove. A screw is provided at the end of the fixing seat 72 to be threadedly connected to the end of the second support rod 30, so that the second support rod 30 can be fixed in the mounting groove.

[0035] In one embodiment, an adjustment mechanism 80 is provided below the chuck 10 and below the base 60. The adjustment mechanism 80 is used to allow the overall tooling to adaptively conform to the blade surface at multiple angles, avoiding jamming during adjustment.

[0036] Specifically, the adjustment mechanism 80 includes a ball head 81 and an annular groove seat 82. The ball head 81 is connected to the chuck 10 or the base 60. Since the top of the ball head 81 is arc-shaped and connected to the chuck 10 or the base 60, the ball head 81 can rotate relative to the chuck 10 or the base 60, thereby adjusting the angle of the chuck 10 so that the chuck 10 can rotate at any angle. The annular groove seat 82 is used to limit the ball head 81 on the chuck 10 or the base 60.

[0037] A buffer rubber 90 is provided between the ball head 81 and the first support rod 20. The vibration energy generated by the cutting tool is absorbed by the buffer rubber 90 through elastic deformation, preventing the vibration from being transmitted to the tooling body.

[0038] Specifically, the ball head 81 includes a ball 811 and a connecting post 812 connected to the ball 811. The ball 811 is used to abut against the chuck 10 or the base 60. The connecting post 812 is provided with a connecting hole and a thread in the connecting hole. Correspondingly, a stud is installed in the connecting hole to connect the ball head 81 with other components, such as the buffer rubber 90, etc.

[0039] In one embodiment, the chuck 10 includes an upper pressure plate 11, a locking member 12, a connecting block 13, and a lower pressure plate 14. The connecting block 13 is disposed between the upper pressure plate 11 and the lower pressure plate 14 and defines a clamping space between them. The locking member 12 passes through the upper pressure plate 11 and is threadedly connected to the lower pressure plate 14. When it is necessary to clamp the blade, the distance between the upper pressure plate 11 and the lower pressure plate 14 is changed by adjusting the locking member 12, so that the blade is in the clamping space. Then, the locking member 12 is adjusted again so that the upper pressure plate 11 and the lower pressure plate 14 clamp the blade. Specifically, the locking member 12 is a screw, and the screw is threadedly connected to the lower pressure plate 14.

[0040] A groove is provided on the bottom surface of the pressure plate 14, and the shape of the groove is adapted to the shape of the ball 811. This facilitates the rotation of the ball 811 in the groove, thereby making the angle of the chuck 10 easier to adjust. Correspondingly, a groove is also provided on the bottom surface of the base 60. The base 60 and the ball 811 fit the blade surface, which can eliminate adjustment jamming.

[0041] In this application, considering the overall size and the buffering effect on the tooling, the elastic element 40 is set as a spring, with the two ends of the spring abutting against the fixing clamp 50 and the base 60 respectively.

[0042] The locking process of the auxiliary support device in this application is as follows:

[0043] Preliminary locking: After the position is determined, tighten the screws on the sleeve slider 70 and the fixing clamp 50 to fix the first support rod 20, the second support rod 30 and the spring, lock the spring deformation, and form an overall support frame.

[0044] Fine-tuning: Adjust the position of the upper ball head 81 so that the upper pressure plate 11 and the lower pressure plate 14 are parallel to the blade surface. Utilize the characteristic of the connecting block 13 matching the blade thickness, lightly press the blade and then pre-tighten the locking piece 12 on the upper pressure plate 11.

[0045] Stress relief: Slightly retract the screws on the sleeve slider 70 and the fixing clamp 50 to release the internal stress of the first support rod 20 caused by the pre-tightening of the upper pressure plate 11, and avoid the blade being squeezed and deformed.

[0046] Final locking: Fully tighten the screws of the upper pressure plate 11, lower pressure plate 14 and annular groove seat 82 to ensure that there is no relative displacement between the blade and the tooling.

[0047] Processing stage:

[0048] The vibration energy generated by the cutting tool is absorbed by the buffer rubber 90 under the chuck 10 through elastic deformation, preventing the vibration from being transmitted to the main body of the tooling.

[0049] The tooling is rigidly connected to the machine tool table via a fixed base 72 to ensure that the blades do not shift or spring back during processing.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
