Description

Technical Field

[0001] The utility model belongs to the technical field of piston ring assembly detection, and particularly relates to a post-assembly ring pushing device. Background Art

[0002] A piston ring is a metal ring used to be embedded inside a piston groove, and is one of the core components inside a fuel engine. It, together with a cylinder, a piston, a cylinder wall, etc., completes the sealing of fuel gas.

[0003] Among them, piston rings are divided into two types: compression rings and oil rings. Compression rings can be used to seal the combustible mixture inside the combustion chamber; oil rings are used to scrape off the excess oil on the cylinder, and are widely used in various power machinery, such as steam engines, diesel engines, gasoline engines, compressors, hydraulic presses, etc., and are widely used in automobiles, trains, ships, yachts, etc.

[0004] Currently, during the cylinder assembly process, a piston ring assembly is usually sleeved on the cylinder. However, after assembling the piston ring assembly, the missed installation cannot be 100% identified, resulting in a certain risk of missed installation.

[0005] Therefore, based on the above problems, we designed a post-assembly ring pushing device. Summary of the Utility Model

[0006] The utility model aims to solve at least one of the technical problems existing in the prior art. For this purpose, the utility model provides a post-assembly ring pushing device, which solves the technical problem that during the cylinder assembly process, a piston ring assembly is usually sleeved on the cylinder. However, after assembling the piston ring assembly, the missed installation cannot be 100% identified, resulting in a certain risk of missed installation.

[0007] To achieve the above object, according to an embodiment of the first aspect of the utility model, a post-assembly ring pushing device is provided, including a bottom plate, a base connected to the bottom plate, a turntable provided on the base, and a photographing device;

[0008] It further includes: a pushing air cylinder provided on the base, a ring pushing block is connected to the end of the pushing air cylinder, and the ring pushing block is made of rubber material.

[0009] The further improvement lies in that the photographing device includes a pedestal connected to the bottom plate, a photographing camera connected to the pedestal, and an HDMI cable provided on the photographing camera. The photographing camera is used to photograph and store the position of the piston ring after assembly, and the HDMI cable is used to connect to a computer terminal to facilitate transmitting the photographed photos to the computer terminal.

[0010] The further improvement lies in that several circularly distributed cylinder placement molds are provided on the turntable, and each cylinder placement mold is provided with a placement notch.

[0011] Further improvement lies in that an auxiliary disc is connected to the base, and the turntable is rotatably arranged on the auxiliary disc.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] In the present utility model, after the piston is placed in the cylinder placement mold and rotated to the shooting station, the pushing cylinder is used to drive the push ring block to move, so that the push ring block contacts each piston, assisting each piston ring to be stuck in the groove of the cylinder. Then, the side of the assembled piston is photographed by the operating camera in the photographing device, and the position of the assembled piston ring is photographed and stored. Then, the photographed photo is transmitted to the computer terminal through the HDMI cable to identify whether the ring is missing, thereby solving the problem that the missing installation of the piston ring cannot be 100% identified after the piston is assembled with the piston ring assembly, and effectively avoiding the missing installation of the piston ring.

[0017] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0018] As Figure 1 shown, an after-assembly push ring device includes a bottom plate 11, a base 1 connected to the bottom plate 11, an auxiliary disc 122 connected to the base 1, and a turntable 12 rotatably arranged on the auxiliary disc 122;

[0019] As Figure 1 shown, during implementation, it further includes: a photographing device 3, the photographing device 3 includes a pedestal 32 connected to the bottom plate 11, a photographing camera 31 connected to the pedestal 32, and an HDMI cable 33 arranged on the photographing camera 31. The photographing camera 31 is used to photograph and store the position of the assembled piston ring, and the HDMI cable 33 is used to connect to the computer terminal to facilitate transmitting the photographed photo to the computer terminal;

[0020] AsFigure 1 As shown in the figure, during implementation, it further includes: a pushing cylinder 2, which is arranged on the base 1. A pushing ring block 21 is connected to the end of the pushing cylinder 2. The pushing ring block 21 is made of rubber material and is used to protect the outer surface of the piston ring to prevent scratching.

[0021] As Figure 1 shown in the figure, during implementation, it further includes: several cylinder placement molds 121 distributed in a circular pattern are arranged on the turntable 12. Each cylinder placement mold 121 is provided with a placement notch. During installation, a separate cylinder is placed in each cylinder placement mold 121, and the specifications of the cylinder placement molds 121 are selected and installed according to on-site requirements.

[0022] As Figure 1 shown in the figure, in this embodiment, the application document is used in cooperation with a cylinder piston production line. The entire device is controlled by a PLC control system according to a set program, and is equipped with a piston loading and unloading mechanism for placing and removing pistons; it is equipped with an electromagnetic motor for individually driving each cylinder placement mold 121 to rotate. It should be noted that the photographing device 3 is a commercially available product of the prior art, and its working principle has been made public. In addition, this application document only aims to improve the disadvantages that during the existing cylinder assembly process, a piston ring assembly is usually sleeved on the cylinder, but after assembling the piston ring assembly, the missing installation cannot be 100% identified, and there is a certain risk of missing installation, and does not involve other aspects. The working principle of this post-assembly pushing ring device is introduced as follows:

[0023] When this new type is installed and used, the piston is sucked by the suction cup in the piston loading and unloading mechanism and is successively placed in each cylinder placement mold 121 and rotates with the turntable 12.

[0024] After the piston is placed in the cylinder placement mold 121 and rotates to the photographing station, the pushing cylinder 2 is used to drive the pushing ring block 21 to move, so that the pushing ring block 21 contacts each piston in turn to assist each piston ring to be stuck in the groove of the cylinder. Then, the side of the assembled piston is photographed by operating the camera in the photographing device 3, and the position of the piston ring after assembly is photographed and stored. Then, the photographed photo is transmitted to the computer terminal through the HDMI cable 33 to identify whether the ring is missing, which can effectively solve the problem that the missing installation of the piston cannot be 100% identified after assembling the piston ring assembly, thus avoiding the missing installation of the piston ring.

[0025] The above embodiments are only used to illustrate the technical method of the present invention and not to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present invention.
