[0022] To make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some but not all of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0023] The embodiment of the present application provides a powder metallurgy outer ring machining tool, which can solve the defects of the traditional manual feeding mode and the difficulty in guaranteeing the ideal coaxiality of the product.

[0024] Referring to Figure 1 As shown in the figure, the embodiment of the present application provides a powder metallurgy outer ring machining tool, which comprises a clamping body, a positioning block 1 and a pressing assembly. The clamping body comprises a base 40 and a positioning seat 41, and the cross sections of the base 40 and the positioning seat 41 are both circular. The base 40 is provided with a connecting hole 400, through which the base 40 can be conveniently installed on a machining station. The positioning seat 41 is installed on the base 40. The clamping body composed of the base 40 and the positioning seat 41 has a compact structure and is convenient to assemble and disassemble. In use, the positioning seat 41 mainly provides an accurate supporting surface, and the powder metallurgy outer ring can be sleeved on the positioning seat 41. In order to effectively position the powder metallurgy outer ring in the axial direction, the positioning block 1 is arranged at the top of the clamping body and is located on the positioning seat 41. The outer wall of the positioning block 1 is provided with a protruding part 2, and the end face of the protruding part 2 is provided with a clamping surface matched with the inner wall of the powder metallurgy outer ring. The pressing assembly is installed on the clamping body and is connected to the base 40. The pressing assembly is used to press the powder metallurgy outer ring tightly on the top of the clamping body.

[0025] In the overall processing of the powder metallurgy outer ring, the powder metallurgy outer ring is sleeved on the positioning seat 41, and the clamping surface of the protruding part 2 is clamped and self-locked with the inner wall of the powder metallurgy outer ring. The positioning block 1 can be firmly clamped on the inner wall of the powder metallurgy outer ring to prevent movement or shaking during processing, thereby improving the precision and stability of processing. Then, the powder metallurgy outer ring is pressed against the top of the clamping body using the pressing assembly, and the powder metallurgy outer ring is effectively positioned axially and radially by the positioning block 1 and the pressing assembly. The powder metallurgy outer ring processing tool realizes effective positioning and pressing of the powder metallurgy outer ring through compact structural design and reasonable component layout, thereby improving the precision and stability of processing. At the same time, the tool also has the characteristics of being easy to assemble and disassemble, facilitating quick replacement and adjustment during processing, thereby improving processing efficiency.

[0026] In the present application, the protruding part 2 is provided in a helical tooth shape, and the tooth tip of the protruding part 2 is provided in an arc shape. The helical tooth shape has a meshing effect, which realizes more accurate positioning of the powder metallurgy outer ring. When the powder metallurgy outer ring cooperates with the positioning block 1, the powder metallurgy outer ring is effectively self-locked on the positioning seat 41, which can prevent the powder metallurgy outer ring from slipping or shifting during processing to some extent, thereby helping to reduce errors during processing and improving processing precision. The arc shape can more effectively disperse pressure and reduce pressure concentration on a unit area, thereby avoiding damage to the powder metallurgy outer ring.

[0027] In the present application, a plurality of positioning blocks 1 are distributed on the clamping body, the plurality of positioning blocks 1 are arranged to form a ring shape, and positioning grooves 3 adapted to the five claws of the powder metallurgy outer ring are left between adjacent positioning blocks 1. The annularly distributed positioning blocks 1 can provide uniform support for the powder metallurgy outer ring to ensure its stability during processing. At the same time, this design also helps to realize accurate positioning of the powder metallurgy outer ring and reduce processing errors. The positioning grooves 3 left between adjacent positioning blocks 1 are adapted to the five-claw structure of the powder metallurgy outer ring, which means that the tool can tightly wrap the powder metallurgy outer ring to prevent it from moving or deforming during processing.

[0028] In addition, the protruding part 2 is provided on at least one positioning block 1, which can provide more stable positioning and fixing effect, and help to further reduce errors and deformation during processing.

[0029] In the present application, the pressing assembly includes a connecting rod 50 and a pressing plate 51. The connecting rod 50 is arranged on the base 40, and the pressing plate 51 is arranged at the top end of the connecting rod 50. The pressing plate 51 extends to the top of the positioning block 1. The end of the connecting rod 50 away from the pressing plate 51 is connected with a driving member. The driving member is used to drive the connecting rod 50 to move. The driving member is provided in the form of, but not limited to, a hydraulic driving member. By controlling the output of the driving member, the connecting rod 50 can be pulled, so that the pressing plate 51 presses against the top of the powder metallurgy outer ring, thereby ensuring the processing precision of the powder metallurgy outer ring.

[0030] In the application, the pressing plate 51 and the connecting rod 50 are connected through the bolt 6, which is convenient for installing the pressing plate 51 and can disassemble the pressing plate 51, so as to adapt to the powder metallurgy outer ring with different processing requirements.

[0031] In some optional embodiments, referring to Figure 2 The powder metallurgy outer ring provided by the embodiment of the application comprises a ring body 70 and a clamping portion 71, wherein the clamping portion 71 is arranged on the inner wall of the ring body 70, the clamping portion 71 is arranged as an inner groove cut on the inner wall of the ring body 70, and the protruding portion 2 is clamped in the inner groove. The groove wall of the inner groove is arranged as a bevel tooth shape opposite to the protruding portion 2. The clamping portion 71 of the application realizes stable clamping through the protruding portion 2 in the tooling, thereby ensuring the stability and accuracy of the powder metallurgy outer ring in the processing or assembly process, and the bevel tooth shape groove wall can form close meshing with the protruding portion 2 in the tooling, greatly improving the stability and reliability of the clamping. Secondly, the bevel tooth shape design has certain self-locking characteristics, which helps to prevent accidental movement or falling of the powder metallurgy outer ring during processing or use.
