[0002] In order to facilitate the processing and maintenance of gears, it is generally necessary to fix the gears through an inner ring positioning structure for easy operation.

[0003] For example, Chinese patent "CN220463632U" discloses "a gear processing inner ring positioning mechanism", which drives the connecting wheel to rotate through a motor, so that the interlocking wheel meshing with the connecting wheel rotates inside the connecting plate, so that the moving block slidably connected to the interlocking wheel slides inward, and then the moving block drives the fixed block to slide inward, and the fixed block drives the mounting block to slide inward, so that the distance between the mounting blocks changes, which is convenient for positioning gears of different sizes. However, although the above mechanism can also position and fix different types of gears, it is self-locking by motor drive, which not only increases energy consumption and costs, but also the adjustment range is limited by the diameter of the interlocking wheel. The larger the adjustment range, the larger the size of the interlocking wheel, which indirectly leads to a larger overall volume. Utility Model Content

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1 and Figure 3As shown, the embodiment of the utility model proposes an inner ring positioning structure for gear machining, which is used to install the gear body 2, including:

[0023] The mounting rod 1 is arranged along the axial direction of the gear body 2;

[0024] The positioning assembly includes a plurality of fixed plates 7 arranged along the circumference of the mounting rod 1, an adjusting member slidably arranged on the mounting rod 1 and connected to the plurality of fixed plates 7, and a driving member transmission-connected to the adjusting member. When the driving member drives the adjusting member to slide on the mounting rod 1, each fixed plate 7 synchronously abuts against the inner ring of the gear body 2, or is separated from it.

[0025] In the embodiment of the utility model, the mounting rod 1 is used as the bearing body of the positioning assembly, and with the cooperation of the mounting rod 1 and the positioning assembly, when the gear body 2 that needs to be processed and repaired is positioned and installed, the inner ring of the gear body 2 is sleeved on the mounting rod 1, and the gear body 2 is placed on one of the fixing plates 7. The adjusting member is adjusted by the driving member to make the adjusting member slide on the mounting rod 1, so that each fixing plate 7 is adjusted by the adjusting member and synchronously moves along the radial direction of the gear body 2, and gradually makes each fixing plate 7 move away from each other and abut against the inner ring of the gear body 2, so as to realize the centering movement of each fixing plate 7, and quickly complete the positioning and installation of the gear body 2. The entire positioning assembly is installed on the mounting rod 1 and arranged along its axial direction. It is small in size, can achieve self-locking under the action of the driving member, is easy to adjust, has a simple structure and low manufacturing cost, and has a large adjustable range, which is suitable for the processing and maintenance of gear bodies of different sizes.

[0026] like Figure 3 As shown, the adjusting member includes two movable rings 8 sleeved on the mounting rod 1 and a plurality of adjusting rods 4 rotatably arranged on the movable rings 8, and the plurality of adjusting rods 4 are rotatably connected to the corresponding fixed plates 7 respectively; the driving member includes two threaded blocks 9 slidably clamped on the mounting rod 1 and a bidirectional screw 10 penetrating the mounting rod 1 and threadedly connected to the two threaded blocks 9, and the two threaded blocks 9 are respectively connected to the two movable rings 8.

[0027] In the embodiment of the utility model, when the gear body 2 is positioned and fixed by the positioning assembly, each fixing plate 7 in the initial state is close to the mounting rod 1, so that the size of the arc space formed by each fixing plate 7 is convenient for the installation of gear bodies 2 of various sizes, and then the gear body 2 to be installed is placed in the top fixing plate 7, and the bidirectional screw 10 is rotated, so that the two threaded blocks 9 are driven to approach each other in the mounting rod 1 under the drive of the bidirectional screw 10, so that the two moving rings 8 are close to each other in the mounting rod 1, so that the angle between the corresponding two adjustment rods 4 gradually decreases, and the spacing between the fixing plate 7 and the mounting rod 1 becomes larger. Since the top fixing plate 7 is used to carry the gear body 2, the gear body 2 will be moved up by the top fixing plate 7 when adjusting, and finally each fixing plate 7 is abutted against the inner ring of the gear body 2 to achieve fixation. By adjusting the position of each fixing plate 7 in this way, different types of gear bodies 2 can be fixed.

[0028] Specifically, both ends of the fixing plate 7 are fixed with limiting parts 11, so that the fixing plate 7 forms a limiting channel for installing the gear body 2. The limiting parts 11 can ensure the stability of the gear body 2 when it is placed on the fixing plate at the top, and it is not easy to fall. It can also limit the gear body 2 when the gear body 2 is processed and repaired, and ensure stability. In addition, the fixing plate 7 is arc-shaped, which can make the shape of the fixing plate 7 closer to the shape of the inner ring of the gear body 2, thereby improving the quality of positioning and fixing. In addition, the surface of the fixing plate 7 is provided with an anti-skid pad 12. When the fixing plate 7 drives the anti-skid pad 12 provided thereon to abut against the inner ring of the gear body 2, the friction between the fixing plate 7 and its inner ring can be increased, further ensuring the stability of positioning and fixing.

[0029] Specifically, Figure 2 As shown, an anti-skid knob 5 is provided at the end of the mounting rod 1, and a bidirectional screw rod 10 passes through the end of the mounting rod 1 and is connected to the anti-skid knob 5. The setting of the anti-skid knob 5 facilitates manual adjustment of the bidirectional screw rod 10 and facilitates operation.

[0030] like Figure 1 As shown, it also includes a base 3 , and the mounting rod 1 is provided with a rotating rod 6 , and the rotating rod 6 passes through the base 3 .

[0031] In the embodiment of the utility model, the mounting rod 1 and the matching positioning assembly can be supported by the base 3, and the mounting rod 1 can be suspended. Moreover, under the action of the rotating rod 6, after the gear body 2 is installed on the mounting rod 1, it can be rotated to fully process and repair the gear body 2. Figure 2As shown, a bolt 13 is threadedly connected to the base 3, and one end of the bolt 13 is in contact with the rotating rod 6. After the gear body 2 is rotated, the bolt 13 can be screwed to make one end of the bolt 13 in contact with the rotating rod 6, thereby stopping the rotating rod 6 and preventing the gear body 2 from rotating again during processing and maintenance.

[0032] In summary, when positioning and installing different types of gear bodies 2, by turning the anti-slip knob 5, the two-way screw 10 drives the two movable rings 8 to move closer on the mounting rod 1, thereby reducing the angle between the two adjustment rods 4 and increasing the spacing between the fixed plate 7 and the mounting rod 1 until all the fixed plates 7 are in contact with the inner ring of the gear body 2. This can be suitable for positioning and installing different types of gear bodies 2, and the overall structure is simple and small in size for easy placement and transportation. After adjusting the movable ring 8, self-locking can be achieved under the action of the two-way screw 10, and the operation is simple. The overall manufacturing cost is low, and it is convenient for mass production.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
