Description

Technical Field

[0001] The present invention belongs to the technical field of piston ring assembly, and particularly relates to a piston ring assembly production line. Background Art

[0002] A piston ring is a metal ring used to be embedded inside a piston groove. Piston rings are divided into two types: compression rings and oil rings. Compression rings can be used to seal the combustible mixture in the combustion chamber; oil rings are used to scrape off the excess oil on the cylinder. A piston ring is a metal elastic ring with a large outward expansion deformation, which is assembled into a corresponding annular groove with the same cross-section. For reciprocating and rotating piston rings, relying on the pressure difference of gas or liquid, a seal is formed between the outer circular surface of the ring and the cylinder and one side of the ring and the ring groove.

[0003] As shown in a piston ring assembly device disclosed in a Chinese invention patent publication No. CN106914853A, the existing piston assembly device has low working efficiency in the actual assembly process and needs to be produced separately, and cannot form an efficient assembly line production process. Therefore, we have specially designed a piston ring assembly production line. Summary of the Invention

[0004] The purpose of the present invention is to provide a piston ring assembly production line for the above-mentioned existing technical problems, achieving the effect of automatic assembly and improving production efficiency.

A second connecting arm is provided on the second movable bracket, and the first connecting arm connects the press-fitting sleeve to the second movable bracket. The press-fitting sleeve includes a second cylinder body and a second pushing device. A second cavity is provided inside the second cylinder body. The second pushing device is arranged inside the second cavity. A push block is connected to the second pushing device, and a counterbore is provided on the push block;

[0015] Wherein, both the first movable bracket and the second movable bracket include a smooth rod, a first motor and a first lead screw. Both the first connecting arm and the second connecting arm include a first connecting head and a second connecting head. The first connecting head is connected to the smooth rod, and the second connecting head is connected to the fitting sleeve / press-fitting sleeve. A platform protrusion is formed by extending outward from the first connecting head. The first lead screw is threadedly connected to the platform protrusion, and the first motor drives the connecting arm to move up and down through the threaded cooperation between the first lead screw and the platform protrusion.

[0016] In this technical solution, the assembly component and the press-fitting component are combined to assemble the piston and the piston ring.

[0017] In the above technical solution, further, the detection mechanism includes:

[0018] An industrial camera, the industrial camera is connected with a fixed bracket. The fixed bracket connects the industrial camera to the working end face and is erected on the upper side of the conveying mechanism;

[0019] An image screening system, the image screening system is connected to the industrial camera and the control system. The industrial camera uploads the taken pictures to the image screening system, and the image screening system conducts comparison and screening and displays the non-conforming pistons on the control system.

[0020] In this technical solution, the image screening system screens and compares the images uploaded by the industrial camera, and finds out the non-conforming pistons therefrom, such as the situation where the piston ring is not inserted into the piston slot or part of the piston ring appears outside the piston slot, and displays the non-conforming pistons through the control system after screening. It is convenient for the staff to screen out.

[0023] A driving device, which includes a second motor, a driving wheel and a driven wheel. The driving wheel and the driven wheel are connected to the conveyor belt, and the second motor drives the driving wheel and cooperates with the driven wheel to control the operation of the conveyor belt.

A connecting groove is correspondingly arranged in the middle section of the clamping member for the columnar protrusion.

[0027] In this technical solution, the handle rod of the piston is connected to the installation groove through the connecting groove and fixed to the columnar protrusion. And the handle rod part of the piston presses the fixed edges on both sides of the opening groove, thereby achieving an interference fit, making the connection between the piston and the conveying mechanism firm. At the same time, the end face of the fixed edge is arc-shaped, which can well prevent the piston from swinging.

[0029] An induction component, which includes a transmitter and a receiver. The transmitter and the receiver are symmetrically arranged on both sides of the conveyor belt and correspond to the assembly component;

[0030] Among them, the receiver is signal-connected to the control system. The control system controls the conveyor belt to convey the piston. After the piston blocks the signal emitted by the transmitter, the receiver sends a signal to the control system, and the control system controls the first assembly mechanism.

[0031] In this technical solution, when the conveying mechanism conveys the piston past the induction component, the laser signal between the transmitter and the receiver will be interrupted. When the receiver cannot receive the transmitter signal, it sends a signal to the control system, and the control system controls the first assembly mechanism to start.

[0037] A second assembly mechanism, the second assembly mechanism is the same as the first assembly mechanism and both include an assembly component and a press-fitting component;

[0038] Wherein, on one side of the end of the connecting column arranged in the sleeve of the assembly component in the second assembly mechanism, there is an extension section. A mating hole is formed in the extension section. The mating hole cooperates with the piston and closes the card slot on the upper end of the piston where a piston ring has been connected.

[0039] In this technical solution, the first assembly mechanism is used to assemble the piston ring into the first card slot on the piston, and the second assembly mechanism is used to assemble the piston ring into the second card slot on the piston ring. Further, it can also be assembled by setting a third assembly mechanism. The third assembly mechanism is the same as the second assembly mechanism, but the depth of the mating hole in the extension section of the third assembly mechanism is greater than that of the mating hole in the second assembly mechanism. Thus, the extension section on the third assembly mechanism can close the card slots on the piston where multiple piston rings are connected.

[0040] In the above technical solution, further, it further includes:

[0041] A marking component, the marking component includes a sensor, a warning light and a sound generator.

[0068] Embodiment 2:

[0069] This embodiment provides a piston ring assembly production line. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0070] The first assembly mechanism 2 includes

[0071] An assembly component 21. The assembly component 21 includes a first movable bracket 211 and a fitting sleeve 212. A first connecting arm 213 is provided on the first movable bracket 211, and the connecting arm connects the fitting sleeve 212 to the first movable bracket 211. The fitting sleeve 212 includes a first cylinder body 2121 and a first pushing device 2125. A first cavity 2122 is provided in the first cylinder body 2121. The lower end of the first cylinder body 2121 is set as the assembly end. The upper end of the first cylinder body 2121 is connected to the first pushing device 2125. A connecting column 2123 is provided in the first cavity 2122. A connecting protrusion 2124 is provided between the connecting column 2123 and the wall surface of the first cavity 2122. One end of the connecting column 2123 inside the assembly end of the first cylinder body 2121 is set as a flared end. Multiple convex ribs are formed on the flared end of the connecting column 2123, and the multiple convex ribs form a limiting level and clamp the piston ring. The first pushing device 2125 is arranged at the upper end of the fitting sleeve 212 and extends into the first cavity 2122. The first pushing device 2125 pushes the piston ring to displace step by step along the flared end.

[0072] Press-fitting assembly 22, the press-fitting assembly 22 includes a second movable bracket 221 and a press-fitting sleeve 222. A second connecting arm 223 is provided on the second movable bracket 221. The first connecting arm 213 connects the press-fitting sleeve 222 to the second movable bracket 221. The press-fitting sleeve 222 includes a second cylinder body 2221 and a second pushing device 2223. A second cavity 2222 is provided inside the second cylinder body 2221. The second pushing device 2223 is arranged inside the second cavity 2222. A push block 2224 is connected to the second pushing device 2223, and a counterbore is provided on the push block 2224;

[0073] Wherein, both the first movable bracket 211 and the second movable bracket 221 include a smooth rod, a first motor and a first lead screw. Both the first connecting arm 213 and the second connecting arm 223 include a first connecting head and a second connecting head. The first connecting head is connected to the smooth rod, and the second connecting head is connected to the mounting sleeve / press-fitting sleeve 222. A platform protrusion is formed by extending outward from the first connecting head. The first lead screw is threadedly connected to the platform protrusion. The first motor drives the connecting arm to move up and down through the threaded cooperation between the first lead screw and the platform protrusion.

[0074] It can be seen from this embodiment that the first assembly mechanism 2 includes an assembly component 21 and a press-fitting component 22;

[0075] The assembly component 21 includes a first movable bracket 211 and a mounting sleeve 212. A first connecting arm 213 is connected to the first movable bracket 211. The first connecting arm 213 mounts the mounting sleeve 212 to the first movable bracket 211. The mounting sleeve 212 includes a first cylinder body 2121 and a first pushing device 2125. A first cavity 2122 is formed inside the first cylinder body 2121. The lower end of the first cylinder bottom is in a flared shape and is set as the assembly end. The first pushing device 2125 is installed at the upper end of the first cylinder body 2121. A connecting column 2123 is formed inside the first cavity 2122. A connecting protrusion 2124 is integrally formed between the connecting column 2123 and the first cavity 2122. The first cylinder body 2121, the connecting column 2123 and the connecting protrusion 2124 are integrally cast. The lower end of the connecting column 2123 is in a flared shape and extends into the assembly end and is provided with a flared end. Multiple convex ribs are formed on the flared end, and the multiple convex ribs are combined with each other to form a limiting level on the wall surface of the flared end;

[0076] The piston ring is connected to the connecting column 2123, and the opening on the piston ring is connected to the connecting protrusion 2124. Thus, the piston rings are stacked on the connecting column 2123, thereby achieving the effect of automatic feeding. It only needs to add the piston rings on the connecting column 2123 after they are used up, improving the production efficiency. After stacking, the limiting level formed by the convex ribs on the flared end can limit and hold the piston rings, making them unable to be connected into the flared end. When in use, when the first pushing device 2125 is started to apply force to the piston, the piston passes through step by step at the convex ribs;

[0077] The press-fitting assembly 22 includes a second movable bracket 221 and a press-fitting sleeve 222. A second connecting arm 223 is connected to the second movable bracket 221. The second connecting arm 223 connects the press-fitting sleeve 222 to the second movable bracket 221. The press-fitting sleeve 222 includes a second cylinder body 2221 and a second pushing device 2223. A second cavity 2222 is formed inside the second cylinder body 2221. The second pushing device 2223 is installed inside the second cavity 2222. A push block 2224 is connected to the second pushing device 2223. A counterbore is formed in the push block 2224. The second pushing device 2223 pushes the push block 2224 so that the counterbore sleeves onto the piston. After the counterbore sleeves onto the piston, it pushes the piston ring that has not been caught in the card slot on the piston into the card slot;

[0078] Both the first cylinder body 2121 and the second cylinder body 2221 are made of polymer materials and are light in weight as a whole;

[0079] Both the first movable bracket 211 and the second movable bracket 221 include a polished rod, a first motor, and a first lead screw. Both the first connecting arm 213 and the second connecting arm 223 include a first connecting head, a second connecting head, and a connecting section. The first connecting head and the second connecting head are arranged at both ends of the connecting section. The first connecting head is connected to the polished rod, and the second connecting head is connected to the mounting sleeve / press-fitting sleeve 222. A platform protrusion is formed by extending the first connecting head outward. The first lead screw is threadedly connected to the platform protrusion, thereby forming a lead screw drive structure. The first motor drives the connecting arm to move up and down through the threaded cooperation between the first lead screw and the platform protrusion. Both the first pushing device 2125 and the second pushing device 2223 are electric telescopic rods and are both connected with a pushing member. The pushing member is arc-shaped and is tangent to the connecting column 2123. An activity cover is connected to the upper sides of both the first pushing device 2125 and the second pushing device 2223. The first pushing device 2125, the second pushing device 2223 are bolt-fixed to the activity cover, and the activity cover is threadedly connected to the first cavity 2122 / the second cavity 2222;

[0080] The piston rings are stacked on top of each other and sleeved on the connecting column 2123. After the assembly end is aligned with the piston, the first pushing device 2125 presses the piston rings downward. The piston rings squeeze against each other, thereby pushing the piston rings on the lower side downward. During the displacement of the piston rings, they are expanded by the flared ends until they are connected to the piston. After the piston rings are connected to the piston, the conveying mechanism continuously conveys the piston to the lower side of the press-fitting assembly 22. The second pushing device 2223 pushes the push block 2224, and the piston extends into the counterbore and is tangent to the counterbore wall surface. The end face of the push block 2224 pushes the piston rings that are not connected to the upper clamping groove of the piston into the clamping groove for connection. The convex ribs on the flared ends can prevent the lower piston rings from being squeezed by the gravity of multiple stacked piston rings when not in use, resulting in deformation of the lower piston rings due to long-term stress. The convex ribs restrict the movement of the piston rings when the piston rings are not under the force of the first pushing device 2125, and the convex ribs play a protective role.

[0081] Embodiment 3:

[0082] This embodiment provides a piston ring assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0083] The detection mechanism 3 includes:

[0084] An industrial camera, which is connected to a fixed bracket. The fixed bracket connects the industrial camera to the working end face 11 and is erected above the conveying mechanism;

[0085] An image screening system, which is connected to the industrial camera and the control system. The industrial camera uploads the captured pictures to the image screening system. The image screening system conducts comparison and screening and displays the non-conforming pistons on the control system.

[0086] It can be seen from this embodiment that the detection mechanism 3 includes an industrial camera and a graphic comparison system;

[0087] The industrial camera is connected to a fixed bracket. The fixed bracket straddles the working end face 11 on both sides of the conveying path 13 and fixes the industrial camera directly above the conveying mechanism. Thus, the industrial camera can take pictures of the pistons conveyed by the conveying mechanism and upload the captured pictures to the image screening system for detection. The image screening system screens and compares the images uploaded by the industrial camera and finds the non-conforming pistons therefrom, such as the situation where the piston rings are not clamped into the piston clamping grooves or part of the piston rings appear outside the piston clamping grooves, and displays the non-conforming pistons through the control system after screening. This facilitates the staff to screen them out.

[0088] Embodiment 4:

[0089] This embodiment provides a piston ring assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0090] The conveying mechanism includes:

[0091] A conveyor belt 41, on one side of the conveyor belt 41, an extension edge is formed, and mounting grooves 411 are equidistantly arranged on the extension edge. Columnar protrusions 412 are formed in the mounting grooves 411. Each mounting groove 411 has a number, and sensors are correspondingly arranged according to the numbers.

[0092] A driving device, the driving device includes a second motor 421, a driving wheel 422 and a driven wheel 423. The driving wheel 422 and the driven wheel 423 are connected to the conveyor belt 41. The second motor 421 drives the driving wheel 422 and cooperates with the driven wheel 423 to control the operation of the conveyor belt 41.

[0093] It can be seen from this embodiment that the conveying mechanism includes a conveyor belt 41 and a driving device;

[0094] An extension edge is formed on one side of the conveyor belt 41. A plurality of mounting grooves 411 are equidistantly spaced and formed on the extension edge. On one end face perpendicular to the end face of the conveyor belt 41 in the mounting groove 411, a columnar protrusion 412 is formed. The columnar protrusion 412 is used to connect the piston handle rod (the handle rod of the piston has a hole). The edge of the conveying channel 13 will assist the mounting groove 411 to clamp the piston. At the same time, the distance between adjacent mounting grooves 411 is the same as the distance between the assembly component 21 and the pressing component.

[0095] The driving device includes a second motor 421, a driving wheel 422 and a driven wheel 423. The driving wheel 422 and the driven wheel 423 are both installed on the lower side of the working end face 11. A transverse bracket 14 is formed on the support frame 12 corresponding to the lower side of the working end face 11 for installing the driving wheel 422 and the driven wheel 423 and placing the motor.

[0096] The piston is fixed on the columnar protrusion 412. The second motor 421 drives the driving wheel 422 to cooperate with the driven wheel 423 to drive the conveyor belt 41 to convey the piston. At the same time, the distance between adjacent mounting grooves 411 is the same as the distance between the assembly component 21 and the pressing component. Thus, when the piston is conveyed through the first assembly mechanism 2, a sequential assembly process of pre-assembly and post-compaction can be realized. At the same time, the driving device adopts step-by-step intermittent driving, and the intermittent driving distance is the distance between the assembly component 21 and the press-fitting component 22. At the same time, the distance between adjacent mounting grooves 411 on the conveyor belt 41 matches it, which is convenient for assembly and press-fitting.

[0097] The conveying mechanism assists in conveying the piston, and the cooperation between the piston and the conveying mechanism is simple, which is convenient for loading and unloading, and thus can effectively improve production efficiency.

[0098] Embodiment 5:

[0099] This embodiment provides a piston ring assembly production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0100] The clamping member 6 is arranged in the installation groove 411 , and an opening groove 61 is arranged on the clamping member 6 , and the opening groove 61 divides the clamping member 6 into two parts, a left part and a right part, and a connecting groove 62 is arranged in the middle section of the clamping member 6 corresponding to the columnar protrusion 412 .

[0101] It can be seen from this embodiment that a clamping member 6 is installed in the installation groove 411 to strengthen the fit between the piston and the columnar protrusion 412;

[0102] The clamping member 6 is integrally made of rubber material by integral injection molding. An opening groove 61 is provided on the clamping member 6. The opening groove 61 divides the clamping member 6 into two from top to bottom (the bottom end portion is not disconnected and is still integral), and forms two fixed edges. The opposite surfaces of the fixed edges are arc-shaped, so that the handle of the piston can be tightly held. A connecting groove 62 is formed in the middle section of the clamping member 6 corresponding to the columnar protrusion 412. The clamping member 6 is connected to the mounting groove 411, and the clamping member 6 and the mounting groove 411 are fixed by gluing;

[0103] The handle rod of the piston is connected to the mounting groove 411 by the connecting groove 62 and fixed to the columnar protrusion 412, and the handle rod part of the piston squeezes the fixed edges on both sides of the opening groove 61, thereby achieving an interference fit, so that the connection between the piston and the conveying mechanism is stable, and at the same time, the end face of the fixed edge is arc-shaped, which can effectively prevent the piston from swinging.

[0104] Embodiment 6:

[0105] This embodiment provides a piston ring assembly production line, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0106] The induction component 7 includes a transmitter 71 and a receiver 72. The transmitter 71 and the receiver 72 are symmetrically arranged on both sides of the conveyor belt 41 and correspond to the assembly component 21.

[0107] The receiver 72 signal is connected to the control system, and the control system controls the conveyor belt 41 to convey the piston. After the piston blocks the signal emitted by the transmitter 71 , the receiver 72 sends a signal to the control system, and the control system controls the first assembly mechanism 2 .

[0108] It can be seen from this embodiment that the sensing component 7 includes a transmitter 71 and a receiver 72. The transmitter 71 is a laser transmitter 71, and the receiver 72 is a laser sensor. The transmitter 71 and the receiver 72 are installed on the working end surfaces 11 on both sides of the conveyor belt 41. The transmitter 71 and the receiver 72 correspond to each other and are arranged on the front side of the assembly component 21.

[0109] When the conveying piston of the conveying mechanism passes through the induction component 7, the laser signal between the transmitter 71 and the receiver 72 will be interrupted. When the receiver 72 cannot receive the signal from the transmitter 71, it sends a signal to the control system, and the control system controls the first assembly mechanism 2 to start.

[0114] The first flange 81 and the second flange 82 cooperate to detachably connect the first cylinder body 2121 to the first connector of the first connecting arm 213.

[0118] Among them, on one side of the end of the connecting column 2123 arranged in the mounting sleeve 212 of the assembly component 21 in the second assembly mechanism 9, there is an extension section. A mating hole is provided in the extension section, and the mating hole cooperates with the piston and closes the card slot on the upper end of the piston where the piston ring has been connected.

[0119] It can be seen from this embodiment that a second assembly mechanism 9 is further installed after the first assembly mechanism 2. The second assembly mechanism 9 has the same structure as the first assembly mechanism 2, but an extension section is formed at the end of the mounting sleeve on the assembly component 21 in the second assembly mechanism 9, and a mating hole is provided in the extension section;

[0120] When it comes to assembling piston rings (gas rings and oil rings) into multiple slots on the piston, the first assembly mechanism 2 installs the piston rings into the uppermost slot of the piston. The conveying device transports the piston into the second assembly mechanism 9. During the downward pressing of the fitting sleeve 212 on the assembly component 21 in the second assembly mechanism 9, the extension section is sleeved onto the piston through the fitting hole and closes the slot on the upper side of the piston. Thus, the piston rings are connected to other slots on the piston through the extension section;

[0121] The first assembly mechanism 2 is used to assemble the piston rings into the first slot on the piston, and the second assembly mechanism 9 is used to assemble the piston rings into the second slot on the piston ring. Further, assembly can also be carried out by setting a third assembly mechanism. The third assembly mechanism is the same as the second assembly mechanism 9, but the depth of the fitting hole in the extension section of the third assembly mechanism is greater than that of the second assembly mechanism 9. Thus, the extension section of the third assembly mechanism can close the slots on the piston where multiple piston rings are connected;

At the same time, the sensor is connected to the control system and the image screening system, and the image screening system records the sensor number data;

[0127] During operation, after the control system receives the signal uploaded by the image screening system, it controls the sound generator to emit an alarm sound and sends a signal to the sensor at the corresponding position. The sensor controls the warning light to light up, thus facilitating the inspection by the staff.
