Piston ring stock bin with piston ring guide discharging function

Abstract

The utility model relates to a piston ring stock bin with a piston ring guiding and discharging function, which comprises a bottom plate used for supporting piston rings, a first stand column used for limiting the piston rings, a second stand column used for guiding and positioning the piston rings, and a push head used for pushing out the piston ring at the bottommost layer in the stock bin, and the first stand column and the second stand column are respectively fixed on the bottom plate. The push head is arranged on the bottom plate and connected with the bottom plate through the reset spring. An elastic piece is installed on the bottom plate, is of an inclined face structure and is located on the front portion of the stock bin, and the top end of the inclined face of the elastic piece is higher than the top face of the bottommost piston ring. In the process that the piston ring on the lowermost layer is pushed to move forwards, the piston ring is guided downwards to be separated from the piston ring on the upper layer under the action of the inclined surface of the elastic sheet. The piston ring pushing device solves the problem that in the process that the piston ring on the lowermost layer is pushed out by the pushing head, due to the oil film bonding force between the piston rings, the piston ring on the lowermost layer is possibly bonded by the piston ring on the upper layer and is difficult to fall off, and the piston ring pushing failure is easily caused.

Description

Technical Field

[0001] The utility model relates to a piston ring material bin with a piston ring guide feeding device. Background Art

[0002] The piston ring silo is a supporting device used in the automatic assembly process of piston rings. In order to facilitate the fully automatic assembly of piston rings and improve the versatility of the piston ring silo and the stability of the push ring, the applicant submitted a patent application with Chinese patent application number 202322781585.2 on October 17, 2023. The application scheme provides a piston ring silo structure, including a bottom plate for supporting the piston ring, a column one for limiting the piston ring, a column two for guiding and positioning the piston ring, and a push head for pushing out a piston ring at the bottom of the silo. Columns one and two are respectively fixed on the bottom plate, and the push head is set on the bottom plate. The push head is connected to the bottom plate through a reset spring. The piston ring silo structure can accommodate multiple piston rings. After pushing the push head to push out a piston ring at the bottom layer, the push head is reset under the action of the reset spring. This piston ring falls on the bottom surface of the cavity in the middle of the bottom plate due to gravity. This is repeated to continuously output the piston ring. The utility model can adapt to piston gas rings and oil scraper rings of different models. However, in this solution, during the process of the push head pushing out the bottom piston ring, due to the oil film adhesion between the piston rings, the bottom piston ring may be bonded by the upper piston ring and difficult to fall off, which may easily lead to failure of pushing the ring. Summary of the invention

The piston ring silo can solve the problem that during the process of a push head pushing out the bottom layer of piston rings, the bottom layer of piston rings may be adhered to the upper layer of piston rings and difficult to fall down due to the adhesion of the oil film between the piston rings, which easily leads to failure in pushing the rings.

[0004] The technical solution provided by the utility model is: a piston ring silo with piston ring guiding and unloading, comprising a bottom plate for supporting the piston ring, a column one for limiting the piston ring, a column two for guiding and positioning the piston ring, and a push head for pushing out a piston ring at the bottom layer in the silo, the column one and the column two are respectively fixed on the bottom plate, the push head is arranged on the bottom plate, and the push head is connected to the bottom plate through a reset spring; a spring sheet is installed on the bottom plate, the spring sheet is an inclined structure, the spring sheet is located at the front of the silo, and the top end of the inclined surface of the spring sheet is flush with or slightly higher than the top surface of the piston ring at the bottom layer.

[0005] The pusher head and the spring piece are symmetrically arranged at two ends of a piston ring at the bottom layer.

[0006] The second column is provided with a piston ring limiting rib plate.

[0007] The bottom plate is provided with a positioning groove for positioning and clamping the silo.

[0008] The front end of the push head is provided with a push head step, and the height of the push head step is the thickness of a piston ring or slightly smaller than the thickness of the piston ring.

[0009] The piston ring silo structure of the utility model can accommodate multiple piston rings. After the piston ring at the bottom layer is pushed out by pushing the push head, the push head is reset under the action of the reset spring. The piston ring falls on the bottom surface of the cavity in the middle of the bottom plate due to gravity. This is repeated to continuously output piston rings. The utility model can adapt to piston gas rings and oil scraper rings of different models.

[0010] The utility model installs a spring sheet at the front of the silo, and the spring sheet is an inclined surface structure. The top of the inclined surface of the spring sheet is higher than the top surface of the bottom piston ring. When the bottom piston ring is pushed forward, the piston ring is guided downward by the inclined surface of the spring sheet, so that it is separated from the upper piston ring. The utility model solves the problem that when the push head pushes out the bottom piston ring, due to the oil film adhesion between the piston rings, the bottom piston ring may be adhered to the upper piston ring and difficult to fall, which may easily lead to the failure of pushing the ring.

The pusher 2 is reset by a spring 5. The column 1 3 and the column 2 4 are respectively fixed on the bottom plate 1. The pusher 2 is arranged on the bottom plate 1 and is located at the bottom of the column 1 3 and the column 2 4. A spring 10 is installed on the bottom plate 1. The spring is an inclined structure or a " "-shaped structure (i.e., the connecting structure of the inclined surface and the horizontal surface), the spring piece is located at the front of the silo, and the top of the inclined surface of the spring piece is slightly higher than the top surface of the bottom piston ring. The push head and the spring piece are symmetrically arranged at both ends of a piston ring of the bottom layer.

[0017] The utility model installs a spring sheet 10 at the front of the silo, and the spring sheet 10 is an inclined surface structure. When the piston ring of the bottom layer is pushed forward, the piston ring is guided downward by the inclined surface of the spring sheet 10, so that it is separated from the piston ring of the upper layer. In order to prevent the piston ring from being deformed by the inclined surface of the spring sheet 10, the spring sheet 10 is connected to the bottom plate 1 in a floating manner by screws 7, that is, the screws fixing the spring sheet 10 do not press the spring sheet 10, and the spring sheet 10 can move up and down to a certain extent.
