[0025] The following is combined with Figure 2-5 This application is described in further detail.

[0026] The utility model embodiment provides a powder metallurgy parts machining anti-deformation tooling, referring to Figure 2 and Figure 3 The anti-deformation tooling for powder metallurgy parts machining includes a base ring 1, a suspension plate inner wall support assembly 2, a conical driving column 3 and a suspension plate outer wall support sleeve 4. The base ring 1 is suitable for clamping by a three-jaw chuck, the connecting piece is plugged into the base ring 1, the suspension plate inner wall support assembly 2 is detachably connected to the base ring 1 and is suitable for supporting the inner wall of the overhanging plate, and the conical driving column 3 is detachably connected to the suspension plate inner wall support assembly 2 and is suitable for driving the suspension plate inner wall support assembly 2 to fit closely with the inner wall of the overhanging plate for support. The suspension plate outer wall support sleeve 4 is detachably connected to the base ring 1, and the suspension plate outer wall support sleeve 4 is sleeved on the connecting piece to support the outer wall of the overhanging plate body.

[0027] It is worth noting that when turning the inner wall of the overhanging plate, it is necessary to remove the inner wall support assembly 2 of the overhanging plate so that it does not interfere with the processing, and at the same time, the outer wall support sleeve 4 of the overhanging plate is sleeved on the overhanging plate and connected to the base ring 1. When turning the outer wall of the overhanging plate, the outer wall support sleeve 4 of the overhanging plate is removed so that it does not interfere with the processing, and at the same time, the inner wall support assembly 2 of the overhanging plate is connected to the base ring 1.

[0028] Reference Figure 2 and Figure 4 The base ring 1 is a rotating body, the inner diameter of the base ring 1 is smaller than the outer diameter of the circular ring, and a docking groove 11 is provided at one end of the base ring 1 close to the connecting piece. The docking groove 11 is an annular groove, and the inner diameter of the docking groove 11 is the same as the inner diameter of the base ring 1. The end of the circular ring away from the overhanging plate is inserted into the docking groove 11, but the flange is located outside the docking groove 11 and abuts against the base ring 1, so that the outer wall support sleeve 4 of the overhanging plate can press it tightly to limit it.

[0029] The inner wall support assembly 2 of the suspended plate includes a base column 21 and a support plate 22. The base column 21 is arranged concentrically with the base ring 1. The base column 21 is inserted into the base ring 1 from the end of the base ring 1 away from the docking groove 11 and is threadedly connected to the base ring 1. The support plate 22 is hingedly connected to the end of the base column 21 close to the connecting piece. There are multiple support plates 22, and the multiple support plates 22 are evenly spaced and arranged at the same end of the base column 21. The inner wall of the corresponding suspended plate fits the outer wall of the corresponding support plate 22. The conical drive column 3 is located between the multiple support plates 22 and is threadedly connected to the base to drive the multiple support plates 22 to open or contract.

[0030] Reference Figure 2 and Figure 4 The base column 21 does not extend into the range of the docking groove 11, the side of the base column 21 away from the docking groove 11 protrudes from the base ring 1, and a driving square column 23 is welded on the side of the base column 21 away from the docking groove 11, and the driving square column 23 protrudes from the base ring 1 and is exposed to the outside. When installing the base column 21 on the base ring 1 or removing the base column 21 from the base ring 1, the staff can clamp the driving square column 23 with a wrench to drive the base column 21 to rotate, making the disassembly and assembly of the base column 21 more convenient.

[0031] A hinged protrusion is welded on one end of the base column 21 close to the support plate 22, and a rotating protrusion is welded on one end of the support plate 22 close to the base column 21. The hinged protrusion and the rotating protrusion are hingedly connected through a hinge shaft, thereby realizing a hinged connection between the support plate 22 and the base column 21.

[0032] Reference Figure 2 and Figure 4 A linkage bar 221 is integrally formed on the outer wall of the support plate 22, and at least two adjacent overhang plates are fitted with the same support plate 22. The linkage bar 221 is located between the two adjacent overhang plates, and the two ends of the linkage bar 221 are respectively abutted against the two adjacent overhang plates. When the base ring 1 rotates with the three-jaw chuck, the connecting piece will also rotate synchronously under the action of the linkage bar 221, and it is not easy to form relative rotation with the base ring 1. The side of the linkage bar 221 close to the flange abuts against the flange, thereby being able to achieve axial limitation of the connecting piece and improve stability during processing. The linkage bar 221 does not protrude from the overhang plate along the radial direction of the circular ring, and thus the linkage bar 221 does not interfere when the overhang plate is cut.

[0033] The conical driving column 3 is concentric with the base ring 1, and the end of the conical driving column 3 with a smaller outer diameter is close to the base column 21. The base column 21 is provided with a thread groove at the center of one end of the conical driving column 3, and a thread column 31 is welded at the center of one end of the conical driving column 3 close to the base column 21. The thread column 31 is inserted into the thread groove and is threadedly connected with the base column 21. Therefore, the multiple support plates 22 can be driven to be in an open state by rotating the conical thread column 31.

[0034] Reference Figure 2 and Figure 4 A manual drive column 32 is welded to one end of the tapered drive column 3 away from the threaded column 31. The manual drive column 32 is exposed to the outside in a cantilevered state so that the staff can drive the manual drive column 32 to drive the tapered drive column 3 to rotate. Two flat grooves are symmetrically provided on the outer peripheral wall of the manual drive column 32. When it is difficult to drive the tapered drive column 3 to rotate by hand, a wrench can be used to clamp the manual drive column 32 through the two flat grooves to facilitate the rotation of the tapered drive column 3.

[0035] In order to make the support plate 22 fit better with the outer wall of the conical driving column 3, the inner wall of the support plate 22 is provided with a conical arc surface that fits with the conical driving column 3, so that the conical driving column 3 can stably support the support plate 22 in the open state.

[0036] Reference Figure 3 and Figure 4 The hanging plate outer wall support sleeve 4 is concentric with the base ring 1, and a flange groove for inserting the flange is provided at one end of the hanging plate outer wall support sleeve 4 close to the base ring 1, thereby limiting the axial movement of the connecting piece. Multiple hanging plates are inserted into the inner hole of the hanging plate outer wall support sleeve 4, and the outer walls of the multiple hanging plates are all in contact with the inner wall of the hanging plate outer wall support sleeve 4. The turning tool can enter the inner hole of the hanging plate outer wall support sleeve 4 to process the inner wall of the hanging plate.

[0037] Reference Figure 3 and Figure 5 A thread groove 12 is provided on one side of the base ring 1 on which the docking groove 11 is provided. The thread groove 12 is concentric with the base ring 1. A thread ring 41 is integrally formed at one end of the hanging plate outer wall support sleeve 4 close to the base ring 1. The thread ring 41 is inserted and threadedly installed in the thread groove 12. The flange will be clamped and limited by the hanging plate outer wall support sleeve 4 and the base ring 1.

[0038] The bottom of the butt joint groove 11 is provided with a slot 13, into which the overhanging plate can be inserted, and the number of the slots 13 is the same as the number of the overhanging plates and corresponds one to one. When turning the ring, the overhanging plate inner wall support assembly 2, the conical driving column 3 and the overhanging plate outer wall support sleeve 4 can be removed from the base ring 1, and then the direction of the connector is reversed to insert the overhanging plate into the slot 13.

[0039] Reference Figure 3 and Figure 5 A rubber sleeve 14 is provided in the slot 13, and the outer peripheral wall of the rubber sleeve 14 fits with the circumferential groove wall of the slot 13. The rubber sleeve 14 is glued in the slot 13 by strong glue, and the overhanging plate is inserted into the rubber sleeve 14 with interference fit, so that the overhanging plate is not easy to be separated from the slot 13, thereby improving the stability during the processing of the ring.

[0040] The implementation principle of the anti-deformation tooling for machining powder metallurgy parts in the embodiment of the present application is as follows: when turning the inner wall of the overhanging plate, it is necessary to remove the inner wall support assembly 2 of the overhanging plate so that it does not interfere with the machining, and at the same time, the outer wall support sleeve 4 of the overhanging plate is sleeved on the overhanging plate and connected to the base ring 1. When turning the outer wall of the overhanging plate, remove the outer wall support sleeve 4 of the overhanging plate so that it does not interfere with the machining, and at the same time, connect the inner wall support assembly 2 of the overhanging plate to the base ring 1. When turning the outer wall of the overhanging plate, the support plate 22 can stably support the inner wall of the overhanging plate, and when turning the inner wall of the overhanging plate, the outer wall support sleeve 4 of the overhanging plate can stably support the outer wall of the overhanging plate. In addition, when turning the circular ring, the overhanging plate can be inserted into the slot 13, so that the overhanging plate can be stably supported during the entire turning process, and it is not easy to deform and affect the quality.

[0041] The conical drive column 3 is threadedly connected to the base column 21 to drive the multiple support plates 22 to an open state and a retracted state. After being opened, the multiple support plates 22 can fit together with the corresponding overhanging plates to play a supporting role. At the same time, under the action of the conical drive column 3, the overhanging plate support is more stable. When the connecting part needs to be removed from the base ring 1, the conical drive column 3 is removed from the base column 21, and the multiple support plates 22 will be in a retracted state to allow the connecting part to pass smoothly. The whole process does not require the base ring 1 to be removed from the three-jaw chuck, the operation is convenient, and the processing efficiency can be improved.

[0042] Although the disclosure is as above, the protection scope of the disclosure is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the disclosure, and these changes and modifications will fall within the protection scope of the utility model.
