Description

Technical Field

[0001] The utility model relates to the technical field of piston ring processing, in particular to a trimming machine for processing automobile piston rings. Background Art

[0002] Piston rings are divided into compression rings and oil rings. Their common feature is that they all have a cut-out spring sheet, which acts on a metal ring embedded in the piston groove structure. The compression ring can be used to seal the combustible mixture in the combustion chamber, and the oil ring is used to scrape off excess oil on the cylinder.

[0003] When a problem occurs with an automobile piston, a new piston ring can be replaced to reduce the maintenance cost of automobile parts and is easy to install. Therefore, it plays an important role in the processing of piston rings. However, it is currently very inconvenient to grind the opening of the piston ring because the piston ring is soft in texture and is prone to shaking during processing, which increases the difficulty of processing. For this reason, this scheme provides a trimming machine for automobile piston ring processing. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a trimming machine for processing automobile piston rings, comprising: a trimming machine housing, the inner wall of the trimming machine housing is connected to bevel gear one through a bearing, the outer wall of the bevel gear one is rotatably connected to bevel gear two, the inner wall of the bevel gear one is provided with a threaded groove, the inner wall of the threaded groove is connected to a threaded rod through a thread, a pressing plate is installed on the top of the threaded rod, and a movable clamping mechanism is provided on one side of the pressing plate.

[0006] As a preferred embodiment, an optical axis is installed on one side of the bevel gear 2, one end of the optical axis is connected to one side of the trimming machine housing, one end of the optical axis is connected to a sleeve rod, and the bottom of the sleeve rod is installed on the inner wall of the trimming machine housing.

[0007] The technical effect of adopting the above-mentioned further scheme is: when the staff needs to trim the piston ring incision, they first manually rotate the optical axis and then move the threaded rod upward or downward, and then drive the pressing plate to move toward the top of the trimming machine housing, that is, the pressing plate tightly clamps the piston rings of different diameters, and then clamps the incisions of piston rings of different diameters through the mobile clamping mechanism to avoid vibration of the piston ring during the trimming process. At the same time, the mobile clamping mechanism is used to clamp piston rings of different diameters, thereby improving the practicability of the trimming machine. In order to support the internal structure of the trimming machine housing, the bevel gear one is facilitated to rotate normally through its bearing, and the position of the bevel gear two is also supported by the sleeve rod, so that the internal structure can operate normally.

[0008] As a preferred embodiment, the mobile clamping mechanism includes a concave-convex groove on one side of a pressing plate, the inner wall of the concave-convex groove is slidably connected with a clamping part, the inner wall of the clamping part is provided with a straight rod part, two springs are installed at one end of the straight rod part, a clamping ball is installed at one end of the two springs away from the straight rod part, and a clamping plate is installed at the bottom end of the straight rod part.

[0009] The technical effect of adopting the above-mentioned further scheme is: when it is necessary to fix the piston ring cuts of different diameters, after the pressing plate has clamped the piston ring, the staff manually translates the two clamping parts to one side of the piston ring cut, and then moves the straight rod upward until the clamping ball is driven by the spring to clamp on the top of the clamping part, that is, moves to the bottom of the clamping part, and tightly clamps the piston ring cut. The operation steps are simple.

[0010] As a preferred embodiment, a rotating shaft is installed at the bottom end of the threaded rod, a limiting groove is opened at the bottom of the trimming machine housing, the inner wall of the limiting groove is slidably connected to a limiting plate, and one side of the limiting plate is passed through and fixed on one end of the rotating shaft.

[0011] The technical effect of adopting the above-mentioned further scheme is: in order to prevent the threaded rod from automatically rotating during the lifting process, the rotating shaft and the limit plate at the bottom of the threaded rod are matched with the inner wall of the limit groove at the bottom of the trimming machine shell, and at the same time cooperate with the inner wall thread of the bevel gear one. Then, when the optical axis is manually rotated, the threaded rod can only move vertically up and down through the cooperation between the bevel gear two and the bevel gear one.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] The utility model can fix the cutouts of piston rings of different diameters through the cooperation among the bevel gear one, the bevel gear two, the threaded rod, the rotating shaft, the pressing plate, the clamping piece and the clamping plate, so that the workers can avoid the shaking phenomenon of one end of the piston ring cutout during the processing, thereby preventing processing errors and processing more defective products, thereby improving the practicality of the trimming machine.
