[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] Example

[0030] like Figure 1-4 As shown, an embodiment of the present invention provides a positioning tool for processing a reducer gear, comprising a mounting base 1;

[0031] Mounting base 1: The basic support part of the entire tooling, providing a mounting platform for other components.

[0032] Bracket 2: fixed to the side of the mounting base 1, used to support components such as the plane plate 3 and the power hydraulic cylinder 13 to ensure the relative position stability of each component.

[0033] Plane plate 3: Install the propulsion hydraulic cylinder 4 to provide a sliding plane for the push plate 5 so that the push plate 5 can smoothly push the processing debris on its surface.

[0034] Propulsion hydraulic cylinder 4: provides power to push the push plate 5 to move, clean up the debris generated during the processing, and keep the processing area clean.

[0035] Push plate 5: Fitted on the flat plate 3, the flared design can effectively push away the processing debris and prevent the accumulation of debris that affects the processing accuracy.

[0036] Guide rail 6: installed on the mounting base 1, engaged and slidably connected with the sliding base 7, guiding the linear motion of the sliding base 7 and the components thereon.

[0037] Sliding seat 7: can slide on the guide rail 6, and the vertical frame 8 on its side is connected to the clamping hoop 9 to achieve position adjustment of the clamping hoop 9.

[0038] Stand 8: connects the sliding seat 7 and the clamping hoop 9, transmits power, and enables the clamping hoop 9 to move with the sliding seat 7 and fix the gear.

[0039] Clamping hoop 9: The arc shape matches the gear, and the gear is fixed through the clamping groove 10 on it to ensure that the gear is in a stable position during the processing.

[0040] Clamping groove 10: It is provided on the clamping hoop 9 and is used to clamp the gear more firmly and improve the positioning accuracy.

[0041] The rotating rod 11 is rotatably connected to the tension rod 12 at one end and is rotatably connected to the output end of the power hydraulic cylinder 13 at the center, converting the telescopic movement of the power hydraulic cylinder 13 into the expansion or contraction movement of the clamping hoop 9.

[0042] The tension rod 12 is connected to the mounting base 1 at its central symmetric position through a rotating shaft 14 . Under the action of the power hydraulic cylinder 13 , it cooperates with the rotating rod 11 to realize the movement of the clamping hoop 9 .

[0043] Power hydraulic cylinder 13: The fixed end is rotatably connected to one side of the bracket 2, which drives the rotating rod 11 to rotate during extension and contraction, thereby controlling the expansion and contraction of the clamping hoop 9 to achieve the clamping and loosening of gears of different sizes.

[0044] The rotating shaft 14 is fixed on the mounting base 1 and provides a rotation fulcrum for the tension rod 12 to ensure the normal movement of the tension rod 12 and the rotating rod 11.

[0045] The working principle of this reducer gear machining positioning fixture is as follows: when a gear needs to be positioned, the gear is first placed in the appropriate position on the mounting base 1. Then, the power hydraulic cylinder 13 begins to operate. Its telescopic movement drives the rotating rod 11 to rotate around the connection point with the output end of the power hydraulic cylinder 13. The rotation of the rotating rod 11, through the cooperation of the tension rod 12 and the rotating shaft 14, drives the sliding seat 7 to slide on the guide rail 6, thereby causing the clamping hoop 9 at one end of the vertical frame 8 to clamp or release the gear. During the machining process, the thrust hydraulic cylinder 4 can push the push plate 5 to move on the flat plate 3, clearing away the debris generated by the machining, ensuring a clean machining environment and smooth machining.

[0046] like Figure 1 As shown, in some embodiments, the push plate 5 is attached to the flat plate 3 and has a flared shape for pushing away processing debris. The push plate 5 is attached to the flat plate 3 and has a flared shape. This design is intended to more efficiently push away processing debris. During the gear processing process, a large amount of debris is generated. If not cleaned up in a timely manner, it may affect the processing accuracy and even damage the processing equipment. The flared push plate 5 can increase the contact area with the debris, allowing it to be pushed by the hydraulic cylinder 4 to more effectively remove the debris from the processing area, keeping the processing environment clean and tidy, thereby ensuring smooth processing and product quality.

[0047] like Figure 1As shown, in some embodiments, the clamping hoop 9 is arc-shaped to match the gear; the arc-shaped design of the clamping hoop 9 is intended to perfectly match the gear. Precise positioning is crucial during the reduction gear machining process. The arc-shaped clamping hoop 9 closely conforms to the outer contour of the gear, providing stable support and fixation, preventing displacement or shaking during machining, and ensuring gear machining accuracy and quality. This design reflects the positioning tool's emphasis on and commitment to gear machining precision.

[0048] like Figure 1 As shown, in some embodiments, the clamping hoop 9 is provided with equidistant clamping grooves 10; the equidistant clamping grooves 10 can make the clamping force more evenly distributed on the gear, avoiding the situation where the local force is too large or too small, thereby fixing the gear more firmly, improving the stability of the positioning tooling during the processing, and ensuring the accuracy and quality of gear processing.

[0049] like Figure 3 As shown, in some embodiments, the fixed end of the power hydraulic cylinder 13 is rotated to one side of the connection bracket 2; when the power hydraulic cylinder 13 is extended or retracted, its fixed end can rotate around the connection point with the bracket 2, so as to better adapt to the movement requirements of the rotating rod 11, effectively transmit power to the rotating rod 11, and then realize the expansion and contraction action of the clamping hoop 9 to complete the clamping and loosening operations of gears of different sizes.

[0050] like Figure 2 As shown, in some embodiments, the tensioning rod 12 is rotatably connected to a rotating shaft 14 at a central symmetrical position, and the rotating shaft 14 is fixedly connected to the mounting base 1; when the power hydraulic cylinder 13 is working, the tensioning rod 12 rotates around the rotating shaft 14, and cooperates with the rotating rod 11 to convert the telescopic movement of the power hydraulic cylinder 13 into the expansion or contraction movement of the clamping hoop 9, thereby achieving the clamping or loosening of the gear, ensuring the normal operation of the positioning tooling and the effective positioning of the gear.

[0051] like Figure 3 As shown, in some embodiments, the extension and retraction of the power hydraulic cylinder 13 drives the rotating rod 11 to rotate, so that the clamping hoop 9 expands and contracts; when the power hydraulic cylinder 13 is working, the tensioning rod 12 rotates around the rotating shaft 14, and cooperates with the rotating rod 11 to convert the extension and retraction movement of the power hydraulic cylinder 13 into the expansion or contraction movement of the clamping hoop 9, thereby achieving the clamping or loosening of the gear, ensuring the normal operation of the positioning tooling and the effective positioning of the gear.

[0052] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
