Description

Technical Field

[0001] The utility model mainly relates to the technical field of piston ring processing, in particular to a piston ring ellipse-fixing device. Background Art

[0002] A piston ring is a metal ring designed to fit within a piston groove. It has a significant ability to expand and deform outward, fitting into an annular groove with a corresponding cross-section. Piston rings rely on pressure differentials between the ring's outer surface and the cylinder, as well as between the ring and one side of the groove.

[0003] During operation, a piston is subject to various forces, causing its shape to change. Lateral compressive forces exerted perpendicular to the piston pin axis cause the piston's dimensions to decrease in that direction, while increasing in the direction of the piston pin's axis. Furthermore, as the engine operates, the piston expands as the temperature rises. Because the piston pin seat hole, which contains more metal, expands more perpendicular to the piston pin's axis due to thermal expansion. Therefore, piston rings are typically designed with an elliptical shape.

[0004] During the processing of piston rings, it is necessary to process the round piston ring raw material into an elliptical piston ring. Generally, a heat setting method is used. The specific process is to put the round piston ring on an elliptical mold and then put it into a heating furnace for heating and setting.

[0005] During the operation of the specific embodiment, the inventors found the following defects:

[0006] The current elliptical mold generally uses an elliptical metal block to limit the piston ring. Piston rings of different specifications require corresponding elliptical metal blocks. The same elliptical metal block can only perform shaping operations on perfect circular piston rings of the same specification, and has poor adaptability.

[0007] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0030] Refer to the attached Figure 1-3 , a piston ring ellipse device, including a support base 1, the top of the support base 1 is connected to a placement platform 2, a first adjusting groove 3 is opened on one side of the placement platform 2, a first slide groove 4 is opened on the support base 1 at the bottom of the first adjusting groove 3, the top of the first slide groove 4 is slidably connected to a concave support seat 5, a first rotating screw 6 is provided on the concave support seat 5, the first rotating screw 6 is matched and connected to a symmetrically arranged clamping portion 7, a threaded column 8 is connected to the middle of the top surface of the support base 1, and the threaded column 8 is matched and connected to a pressing plate 9;

[0031] This device can facilitate the heat setting operation of the piston ring. When working, the placement table 2 is inserted into the threaded column 8 on the top, and the first adjusting groove 3 is aligned with the concave support seat 5. The first rotating screw 6 is adjusted according to the specifications of the piston ring to make the two clamping parts 7 open at a preset angle. Then, the concave support seat 5 is moved to a suitable position in the first slide groove 4 according to the specifications of the piston ring, and the notch of the perfect circular piston ring can be clamped into the clamping part 7. After the piston ring to be processed is stacked and placed on the top of the placement table 2, it is clamped and limited by the clamping plate 9. Finally, the clamped support base 1 is placed in the heat setting furnace for shaping. Since the clamping part 7 of this device can open different angles according to the specifications of the perfect circular piston ring, and the concave support seat 5 can also slide in the first slide groove 4, it can adapt to perfect circular piston rings of different diameters and has high applicability.

[0032] A second rotating screw 41 is provided in the first slide groove 4, and the second rotating screw 41 is rotatably connected to the support block 42. The support block 42 is provided at the end of the first adjustment groove 3. A first rotating adjustment cap 43 is provided at the end of the second rotating screw 41. The second rotating screw 41 is matched and connected to the sliding block 44. The top of the sliding block 44 is connected to the concave support seat 5. Since the radii of different perfect circular piston rings are different, it is necessary to twist the first rotating adjustment cap 43 according to the radius of the perfect circular piston ring, thereby driving the second rotating screw 41 to rotate, so that the sliding block 44 matching the second rotating screw 41 moves in the first slide groove 4, driving the top concave support seat 5 to move, so as to achieve the purpose of matching perfect circular piston rings with different radii.

[0033] Working grooves 31 are symmetrically opened on both sides of the first adjustment groove 3, and the end of the first rotating screw 6 passes through the working groove 31 to connect to the second rotating adjustment cap 32. The opening sizes of piston rings of different specifications are also inconsistent, so the second rotating adjustment cap 32 is set to rotate the first rotating screw 6, and then open and close the clamping part 7 matching the first rotating screw 6.

[0034] The clamping portion 7 includes a convex clamping plate 71, an outer end of the convex clamping plate 71 is provided with a clamping bevel 72, and a first slider 73 is provided at the bottom of the convex clamping plate 71. The first slider 73 is slidably connected to the position adjustment groove 74 at the top of the concave support seat 5, and the bottom of the convex clamping plate 71 is matched with the first rotating screw 6. The clamping bevel 72 on the outer side of the clamping portion 7 abuts against the notch of the piston ring, which is convenient for subsequent shaping operations. When processing piston rings of different specifications, the first rotating screw 6 can be rotated to enable the two convex clamping plates 71 to open and close synchronously.

[0035] A second adjustment groove 91 is provided at the corresponding position of the clamping plate 9, and a clamping nut 92 is provided on the top of the clamping plate 9. The clamping plate 9 can clamp the stacked piston rings. After the clamping plate 9 is inserted into the threaded column 8, the clamping nut 92 is used to limit and clamp the clamping plate 9, so as to facilitate the shaping of the stacked piston rings.

[0036] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
