Description

Technical Field

[0001] This utility model relates to the technical field of piston ring processing, specifically to a piston ring pusher device. Background Technology

[0002] A piston ring is a metal elastic ring with a large outward expansion deformation, which is fitted into an annular groove with a corresponding cross-section. The reciprocating and rotary piston rings rely on the pressure difference of gas or liquid to form a seal between the outer surface of the ring and the cylinder, as well as between the ring and one side of the annular groove.

[0003] Chinese patent application CN202322781587.1, entitled "A Piston Ring Pushing Structure," discloses a piston ring pushing structure comprising two sets of pushing mechanisms. The first set includes a drive cylinder, a linear guide rail, and a push rod driven by the drive cylinder. The push rod is mounted on a slider of the linear guide rail and faces the piston ring at the bottom of the piston ring hopper. The second set includes a servo motor, a linear guide rail, and a push rod driven by the servo motor. The push rod is mounted on a slider of the linear guide rail and faces the piston ring pushed out by the push rod. However, the above patent has the following shortcomings: the hopper, i.e., the limiting frame, is used to hold several piston rings stacked sequentially. The piston ring pushing equipment on the market operates on the same principle as the above patent, using a plate-shaped pusher to push out the piston ring at the bottom of the hopper. At this time, the weight of the several piston rings at the top is pressed on the bottom piston ring, resulting in high friction when the piston ring is pushed out, which poses a risk of scratches. Therefore, a piston ring pushing device needs to be designed. Utility Model Content

[0004] To address the aforementioned technical problems, the purpose of this utility model is to overcome the issue of scratches caused by the large frictional force experienced by the piston ring when it is pushed out in the prior art.

[0005] To achieve the above objectives, this utility model provides a piston ring pushing device, comprising: a base, a limiting frame mounted on the base, a horizontal drive mechanism mounted on the base, a pusher plate mounted on the moving end of the horizontal drive mechanism and matching the limiting frame for pushing the piston ring located at the bottom, and a pair of lifting units arranged symmetrically about the limiting frame.

[0006] The lifting unit includes a mounting base fixedly mounted on the base, a pusher arm that slides obliquely with the mounting base, a rubber clamping block mounted on the oblique upper end of the pusher arm, an elastic element for pushing the pusher arm away from the limiting frame, a pulley mounted on the end of the pusher arm away from the limiting frame, and a strip guide plate mounted on the moving end of the horizontal drive mechanism and matching the pulley, with its length direction consistent with the moving direction of the pusher plate. The end of the strip guide plate away from the horizontal drive mechanism is obliquely inclined away from the limiting frame to form an oblique portion. The end of the pusher arm near the limiting frame is obliquely inclined upward and slidably connected to the mounting base along the oblique direction.

[0007] Preferably, the limiting frame includes a pair of fixed seats arranged symmetrically, and a pair of mounting parts with height bases protruding from the side of the fixed seats near the other fixed seat. Each mounting part is equipped with a vertical limiting rod, and the tops of several limiting rods are fixedly connected by an arc-shaped stabilizing ring.

[0008] Preferably, a plurality of first guide rods with the same tilt direction as the sliding direction of the pusher arm are fixedly installed on the mounting base, and a sliding sleeve is fitted onto the plurality of first guide rods on the upper surface of the pusher arm. A limiting sleeve located on the side of the sliding sleeve away from the limiting frame is fitted onto the first guide rod.

[0009] Preferably, the upper surfaces of the mounting base and the pusher arm are both equipped with mounting components, and the elastic element is a tension spring with its two ends hooked onto the corresponding mounting components.

[0010] Preferably, the inclined upper end of the pusher arm is recessed with a groove, the rubber clamp is protruding with a locking strip that matches the groove, and the side of the rubber clamp that contacts the piston ring is provided with anti-slip texture.

[0011] Preferably, the horizontal drive mechanism includes a horizontal cylinder mounted on a base, a connecting plate mounted on the moving end of the cylinder, and at least one second guide rod fixedly connected to the connecting plate and arranged parallel to the cylinder. The base is equipped with a guide seat through which the second guide rod slides.

[0012] Preferably, the pusher plate is connected to the connecting plate by a number of mounting bolts.

[0013] According to the above technical solution, the piston ring pushing device provided by this utility model has the following beneficial effects during use: by cooperating with the inclined part and the pulley, a pair of rubber clamps can hold the corresponding piston ring, and the pushing arm slides upward at an inclined angle. Therefore, the pair of rubber clamps can lift the upper piston ring through the held piston ring, reduce the pressure applied to the lower piston ring, and avoid scratches on the piston ring due to excessive friction.

[0022] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0023] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0024] like Figure 1-4As shown, a piston ring pushing device includes: a base, a limiting frame mounted on the base, a horizontal drive mechanism mounted on the base, a pusher plate 1 mounted on the moving end of the horizontal drive mechanism and matched with the limiting frame for pushing the piston ring located at the bottom, and a pair of lifting units arranged symmetrically about the limiting frame.

[0025] The lifting unit includes a mounting base 2 fixedly mounted on the base, a pusher arm 3 that slides obliquely with the mounting base 2, a rubber clamp 4 mounted on the oblique upper end of the pusher arm 3, an elastic element 5 for pushing the pusher arm 3 away from the limiting frame, a pulley 6 mounted on the end of the pusher arm 3 away from the limiting frame, and a strip guide plate 7 mounted on the moving end of the horizontal drive mechanism and matching the pulley 6 with the moving direction of the pusher plate 1. The end of the strip guide plate 7 away from the horizontal drive mechanism is obliquely inclined away from the limiting frame to form an oblique part 8. The end of the pusher arm 3 near the limiting frame is obliquely inclined upward and slidably connected to the mounting base 2 along the oblique direction.

[0026] In the above technical solution, several piston rings are placed into the limiting frame in sequence. Under the action of gravity, the piston ring at the bottom will contact the base. The moving end of the horizontal moving mechanism moves close to the limiting frame, driving the strip guide plate 7 and the pusher plate 1 to move together. The inclined part 8 on the strip guide plate 7 first contacts the pulley 6. As the strip guide plate 7 continues to move, the inclined part 8 will push the pulley 6 closer to the limiting frame. The pusher arm 3 slides upward along the inclined direction, so that the rubber clamp 4 contacts the outer wall of the piston ring. The strip guide plate 7 continues to move, and the inclined part 8 will continue to push the pulley 6 closer to the limiting frame. The pusher arm 3 continues to slide upward along the inclined direction. A pair of rubber clamps 4 clamp the corresponding piston ring from both sides and will drive the clamped piston ring to slide upward, separating it from the piston ring below, reducing the pressure applied to the bottom piston ring.

[0027] The strip guide plate 7 continues to move, and the pulley 6 slides from the inclined part 8 onto the strip guide plate 7. After the pulley 6 slides onto the strip guide plate 7, the pusher plate 1 will move with the piston ring located at the bottom, thereby pushing the piston ring located at the bottom out of the limiting frame. Since most of the piston rings above are lifted upwards, and the piston ring located at the bottom has less friction when sliding, it can avoid excessive friction causing scratches.

[0028] After the piston ring at the bottom is pushed out of the limiting frame, the horizontal moving mechanism drives the pusher plate 1 and the strip guide plate 7 to return to their original positions. The pusher plate 1 is first pulled out of the limiting frame, and then the pulley 6 slides from the strip guide plate 7 to the inclined part 8. The rubber clamp 4 moves away from the limiting frame, thereby releasing the clamped piston ring and putting down several piston rings that have been lifted.

[0029] In a preferred embodiment of the present invention, the limiting frame includes a pair of fixed seats 9 arranged symmetrically. A pair of mounting parts 10 with height bases protruding from one side of the fixed seat 9 near the other fixed seat 9 are provided. Each mounting part 10 is equipped with a vertical limiting rod 11. The tops of several limiting rods 11 are fixedly connected by an arc-shaped stabilizing ring 12.

[0030] In the above technical solution, the gap between the mounting part 10 and the base is a discharge channel, and the pusher plate 1 will push the piston ring located at the bottom out from the discharge channel.

[0031] In a preferred embodiment of the present invention, a plurality of first guide rods 13 with the same tilt direction as the sliding direction of the pusher arm 3 are fixedly installed on the mounting base 2. The upper surface of the pusher arm 3 is fitted with a sliding sleeve 14 that is slidably sleeved on the plurality of first guide rods 13. A limiting sleeve 15 located on the side of the sliding sleeve 14 away from the limiting frame is sleeved on the first guide rod 13.

[0032] In the above technical solution, when the pulley 6 slides from the strip guide plate 7 to the inclined part 8, the tension spring will pull the sliding sleeve 14 to slide close to the limiting sleeve 15 on the first guide rod 13 until the sliding sleeve 14 contacts the limiting sleeve 15. The limiting sleeve 15 can play a limiting role, so that after the inclined part 8 separates from the pulley 6, it can contact the pulley 6 again to push the pulley 6 to slide.

[0033] In a preferred embodiment of this utility model, the upper surfaces of the mounting base 2 and the pusher arm 3 are both equipped with mounting components, and the elastic element 5 is a tension spring with its two ends hooked onto the corresponding mounting components.

[0034] In the above technical solution, when the pulley 6 contacts the inclined part 8, as the strip guide plate 7 gradually returns to its original position, the tension spring will pull the sliding sleeve 14 to slide away from the limiting frame on the first guide rod 13 until the sliding sleeve 14 abuts against the limiting sleeve 15.

[0035] In a preferred embodiment of this utility model, the upper inclined end of the pusher arm 3 is recessed with a groove, the rubber clamp 4 is protruded with a locking strip that matches the groove, and the side of the rubber clamp 4 that contacts the piston ring is provided with anti-slip texture.

[0036] In the above technical solution, the anti-slip texture can increase the friction between the rubber clamp 4 and the outer wall of the piston ring, and the setting of the groove and the clip part is conducive to the replacement of the rubber clamp 4.

[0037] In a preferred embodiment of the present invention, the horizontal drive mechanism includes a horizontal cylinder 16 mounted on a base, a connecting plate 17 mounted on the moving end of the cylinder 16, and at least one second guide rod 18 fixedly connected to the connecting plate 17 and arranged parallel to the cylinder 16. The base is equipped with a guide seat through which the second guide rod 18 slides.

[0038] In the above technical solution, the cylinder 16 is started, which drives the connecting plate 17 to move, and the connecting plate 17 drives the second guide rod 18 to slide on the guide rod.

[0039] In a preferred embodiment of this utility model, the pusher plate 1 is connected to the connecting plate 17 by a number of mounting bolts.

[0040] In the above technical solution, the pusher plate 1 can be replaced by loosening the mounting bolts.

[0041] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0042] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0043] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
