Description

Technical Field

[0001] This invention relates to the field of piston ring processing technology, and in particular to a piston ring honing loading and unloading workstation. Background Technology

[0002] After the piston rings are slit, they need to be honed. In existing technology, the slit piston rings are placed in a collection bin. When honing is needed, workers remove the piston rings from the collection bin and place them in the honing machine. Because the piston rings are randomly placed before honing, it is impossible to use a robot to accurately and orderly grasp them. Specialized personnel are required for loading and unloading, which is time-consuming, labor-intensive, and physically demanding. Therefore, there is an urgent need to develop a hopper for orderly storing piston rings, facilitating the grasping by a robotic arm. Summary of the Invention

[0003] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0004] In view of the problems existing in the above and / or existing piston ring honing feeding and discharging processes, the present invention is proposed.

[0005] Therefore, the problem to be solved by this invention is that piston rings cannot be stored in an orderly manner, making it inconvenient for robotic arms to pick them up one by one. This invention provides a piston ring honing and unloading workstation, which can realize the orderly storage of several piston rings stacked together, making it convenient for robotic arms to pick them up, and also making loading and unloading convenient.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a piston ring honing loading and unloading workstation, comprising,

[0007] Main frame;

[0008] The feeding assembly includes a first and second detection rod arranged opposite to each other, and a material tray rotatably connected to the main frame. Several support modules for placing piston rings are arranged on the upper side of the material tray. Each support module includes a first support plate and a second support plate slidably connected to the material tray. The first and second support plates can move towards each other or away from each other. The second support plate is located between the center of the first support plate and the material tray. Several first discharge rods are connected to the first support plate, and several second discharge rods are arranged on the second support plate. The piston rings can be precisely caught between the first and second discharge rods. The upper sides of the first and second discharge rods are... A first detection plate and a second detection plate are fixedly connected. The support module is disposed between the first detection rod and the second detection rod. The upper parts of the first detection rod and the second detection rod are respectively fixedly connected to a first transmitter and a first receiver arranged opposite to each other. The first detection plate and the second detection plate can block the light between the first transmitter and the first receiver. The first detection rod and the second detection rod below the first detection plate are respectively fixedly connected to a second transmitter and a second receiver. The first detection plate and the second detection plate can block the light between the first transmitter and the first receiver. A clamp is connected to the first detection rod below the second transmitter.

[0009] A feeding component that is mounted on the main frame and has the same structure as the feeding component.

[0010] The first transmitter and first receiver, and the second transmitter and second receiver each form a through-beam photoelectric switch. In the feeding assembly, when the light between the first transmitter and the first receiver is blocked, the tray stops rotating. When the light between the second transmitter and the second receiver is blocked, the piston ring between the corresponding first and second feeding rods is pushed upwards a set distance, the piston ring stops rising and falling, and the clamping device actuates to clamp the lower piston ring, preventing the removal of multiple piston rings and ensuring that only one piston ring is removed at a time. The uppermost piston ring is then removed and moved to the next station. In the unloading assembly, when the empty support module rotates to the first and second detection rods... During this process, the support module corresponds to the unloading station. The robotic arm places the processed piston rings between the first and second unloading rods. When the light between the first transmitter and the first receiver is blocked, and the light between the second transmitter and the second receiver is also blocked, the material tray starts to rotate. After rotating to the set position, the material tray stops rotating, and the processed piston rings are placed into the next set of support modules. The above steps are repeated to unload the honed piston rings. This invention can detect whether the piston rings have rotated to the loading station and detect when the unloading process is complete. In the loading assembly, the piston rings are stacked sequentially from bottom to top, arranged in an orderly manner, which is convenient for the robotic arm to grasp. In the unloading assembly, the robotic arm places the piston rings sequentially from bottom to top into the unloading station, which is convenient for the robotic arm to unload. This invention can be used as a hopper for loading and unloading piston rings.

Detailed Implementation

[0041] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0042] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0043] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0044] Example 1

[0045] Reference Figure 1 , Figure 4 and Figures 6-8 This is the first embodiment of the present invention, which provides a piston ring honing loading and unloading workstation that can realize loading before piston ring honing and unloading after cleaning.

[0046] A piston ring honing loading and unloading workstation includes a hopper 100. The hopper 100 includes a main frame 103. The main frame 103 is connected to a loading assembly 101 and a unloading assembly 102 with the same structure. The loading assembly 101 is used to store piston rings to be honed, and the unloading assembly 102 is used to store processed piston rings.

[0047] Specifically, the feeding assembly 101 includes a first detection rod 10119 and a second detection rod 10122 arranged opposite to each other, and a material tray rotatably connected to the main frame 103. The first detection rod 10119 is fixedly connected to the front end of the main frame 103. Several support modules for placing piston rings are arranged on the upper side of the material tray. The support modules include a first support plate 10118 and a second support plate 10111 slidably connected to the material tray. The first support plate 10118 and the second support plate 10111 can be connected to each other. The second support plate 10111 moves in opposite directions, with the center of the first support plate 10118 and the material tray between them. Several first discharge rods 10113 are connected to the first support plate 10118, and several second discharge rods 10112 are arranged on the second support plate 10111. The piston ring can be precisely engaged between the first discharge rods 10113 and the second discharge rods 10112. First detection plates 10121 are fixedly connected to the upper sides of the first discharge rods 10113 and 10112, respectively. The second detection plate 10123 has a support module disposed between the first detection rod 10119 and the second detection rod 10122. The upper parts of the first detection rod 10119 and the second detection rod 10122 are respectively fixedly connected to a first transmitter 10126 and a first receiver 10125 arranged opposite to each other. The first detection plate 10121 and the second detection plate 10123 can block the light between the first transmitter 10126 and the first receiver 10125. A second transmitter and a second receiver 10124 are fixedly connected to the first detection rod 10119 and the second detection rod 10122 below, respectively. The first detection plate 10121 and the second detection plate 10123 can block the light between the first transmitter 10126 and the first receiver 10125. A clamp 10120 is connected to the first detection rod 10119 below the second transmitter. The clamp 10120 is the prior art. In this application, the pneumatic clamp 10120 is preferred.

[0048] The first transmitter 10126 and the first receiver 10125, and the second transmitter and the second receiver 10124, respectively form a through-beam photoelectric switch 204. In the feeding assembly 101, when the light between the first transmitter 10126 and the first receiver 10125 is blocked, the tray stops rotating, causing the stacked piston rings to move upward. When the light between the second transmitter and the second receiver 10124 is blocked, the stacked piston rings continue to move upward a set distance. When the stacked piston rings stop moving upward, the clamp 10120 actuates, clamping the lower piston ring to prevent multiple piston rings from being removed, ensuring that only one piston ring is removed at a time. This causes the piston ring between the corresponding first discharge rod 10113 and the second discharge rod 10112 to be pushed upward. At a fixed distance, the piston ring stops rising and falling, and the topmost piston ring is taken out to the next station. In the unloading assembly 102, when the empty support module rotates between the first detection rod 10119 and the second detection rod 10122, the light between the first transmitter 10126 and the first receiver 10125 is blocked. This position corresponds to the unloading station. The robot arm 400 puts the processed piston ring between the first unloading rod 10113 and the second unloading rod 10112. The piston ring slides down. When the light between the second receiver 10124 and the second transmitter is blocked, the material tray starts to rotate. After rotating to the set position, the material tray stops rotating, and the processed piston ring is put into the next set of support modules. The above steps are repeated to realize the unloading of the honed piston ring.

[0049] Specifically, the support module also includes a lifting and feeding plate 10115. A fixing plate 10110 fixedly connected to the lower side of the first support plate 10118 and to the material tray is fixedly connected to the lower side. A first magnet 1011 is fixedly connected to the upper side of the fixing plate 10110. Two spaced-apart support rotating blocks 1010 are fixedly connected to the upper side of the first support plate 10118. A rotating plate 1015 is rotatably connected between the two support rotating blocks 1010. A first feeding rod 10113 is fixedly connected to the rotating plate 10115. 5. At least two feeding guide rods 10114 are fixedly connected to the rotating plate 1015 at the outward end of the first feeding rod 10113. Several feeding guide sleeves 10117, corresponding one-to-one with the feeding guide rods 10114, are fixedly connected to the upper side of the lifting feeding plate 10115. The feeding guide sleeves 10117 are slidably connected to the corresponding feeding guide rods 10114. A feeding part 101 extending towards the direction of the corresponding second feeding rod 10112 is fixedly provided on the lifting feeding plate 10115. 15a, the feeding section 10115a can be inserted between two spaced-apart second feeding rods 10112, and a second magnet 10116 corresponding to the first magnet 1011 is fixedly connected to the rotating plate 1015; a detection housing 10138 is fixedly connected to the rear end of the main frame 103, and at least one sliding rod 10140 is movably connected to the detection housing 10138. A spring 10141 is fitted on the sliding rod 10140, and a feeding support plate 1 is fixedly connected to the upper side of the sliding rod 10140. 0142, spring 10141 is connected between the lower side of the feeding support plate 10142 and the upper side of the detection housing 10138. The lower side of the sliding rod 10140 extending into the detection housing 10138 is fixedly connected to a connecting plate 10139. The detection housing 10138 is fixedly connected to a proximity switch 10137. When no external force is applied to the feeding support plate 10142, the connecting plate 10139 is above the proximity switch 10137; the lower side of the connecting plate 10139 can contact the proximity switch 10137.

[0050] During material feeding, when an empty support module is in front of the detection housing 10138, the material tray does not rotate. The second magnet 10116 and the first magnet 1011 at the corresponding support module are de-energized, and they have no attractive force. The operator rotates the first feeding rod 10113 backward, causing the feeding guide rod 10114 to abut against the feeding support plate 10142. Further pressing down the feeding guide rod 10114 causes the feeding support plate 10142 to move downward, bringing the connecting plate 10139 into contact with the proximity switch 10137. The feed tray remains stationary. Piston rings are sequentially placed onto the first feed rod 10113, with the lowest piston ring contacting the lifting feed plate 10115. Feeding is complete. The feed guide rod 10114 is pushed forward, disengaging the connecting rod from the proximity switch 10137. The second magnet 10116 aligns with the first magnet 1011, and the first feed rod 10113 is vertical. The second magnet 10116 is energized, causing the piston rings to contact the side away from the first feed rod 10113 and the second feed rod 10112. When the piston rings leave the proximity switch 10113, the feeding is complete. 37. After the set time, the material tray begins to rotate, and the support module filled with piston rings rotates towards the loading station to release the piston rings before honing. During unloading, the lifting unloading plate 10115 is at the set highest position under the action of the pusher plate. The robot arm 400 places the processed piston rings between the first unloading rod 10113 and the second unloading rod 10112 at the unloading station in the unloading assembly 102. The processed piston rings fall onto the lifting unloading plate 10115, and the lifting motor 10127 is activated, causing the pusher plate to move down one position. The thickness of the piston rings is determined by the lifting and unloading plate 10115 sliding down under the action of gravity. The lifting and unloading plate 10115 adheres to the upper side of the push plate, and the newly processed piston rings continue to be stacked on the piston rings at the unloading station. The above actions are repeated. When the push plate descends to the set minimum position, which is not higher than the lower side of the material tray, and the light between the second receiver 10124 and the second transmitter is blocked, the robot arm 400 leaves the unloading assembly 102, the drive motor moves, the material tray rotates, and the next empty support module rotates to the unloading station.

[0051] Specifically, a lifting port is opened on the material tray between the first support plate 10118 and the second support plate 10111. A connecting plate is fixedly connected to the lower part of the main frame 103. A lifting screw 10131 is rotatably connected to the connecting plate. A lifting nut 10133 is threaded onto the lifting screw 10131. A lifting plate 10134 is fixedly connected to the lifting nut 10133. Several guide rods 10132 are arranged on the connecting plate. The lifting plate 10134 is slidably connected to the several guide rods 10132. Several connecting rods 10135 are fixedly connected to the lifting plate 10134. A pusher plate 10143 that can pass through the lifting port is fixedly connected to the upper end of the several connecting rods 10135. The upper side of the pusher plate 10143 can abut against... On the lower side of the lifting and unloading plate 10115, the feeding assembly 101 also includes a guide plate 10136 fixedly connected to the upper part of the main frame 103. Several feeding guide sleeves 10117 corresponding to the feeding guide rods are fixedly connected to the guide plate 10136. The feeding guide rods can slide up and down along the corresponding feeding guide sleeves 10117. The feeding assembly 101 also includes a lifting motor 10127 fixedly connected to the lower part of the main frame 103. A lifting drive wheel 10128 is connected to the lifting motor 10127. A lifting driven wheel 10129 is connected to one end of the lifting screw 10131 that extends downward outside the connecting plate. The lifting drive wheel 10128 is connected to the lifting driven wheel 10129 via the lifting transmission belt 10130.

[0052] When the support module filled with piston rings rotates to the position between the first detection rod 10119 and the second detection rod 10122, the material tray stops rotating, the lifting motor 10127 activates, the lifting drive wheel 10128 rotates, and the lifting driven wheel 10129 rotates via the lifting transmission belt 10130. The lifting driven wheel 10129 then drives the lifting screw 10131 to rotate, and the lifting plate 10134 moves under the action of the lifting screw 10131 and the guide rod 10132. This controls the direction of the lifting motor 10127, causing the lifting plate 10134 to move upwards. The lifting plate 10134 is connected to... Rod 10135 drives pusher plate 10143 to move upward. When pusher plate 10143 contacts lifting and unloading plate 10115, pusher plate 10143 pushes lifting and unloading plate 10115 to move upward. Lifting and unloading plate 10115 pushes several stacked piston rings upward. When the light between the second transmitter and the second receiver 10124 is blocked, the lifting motor 10127 is controlled to continue to operate. When the uppermost piston ring continues to move upward by a set distance, the lifting motor 10127 stops operating, and the external robot arm 400 clamps the uppermost piston ring and sends it into the honing station.

[0053] Specifically, the feeding assembly 101 also includes a transmission box fixedly connected to the main frame 103, a feeding sleeve rotatably connected to the transmission box, a material tray fixedly connected to the feeding sleeve, a connecting shaft passing through the feeding sleeve fixedly connected to the transmission box, and a second detection rod 10122 fixedly connected to the connecting shaft above the material tray; a drive motor that provides power to the transmission box is fixedly connected inside the main frame 103. It is not shown in this application, but it is prior art and does not affect the understanding of the solution.

[0054] When the connecting plate 10139 moves away from the proximity switch 10137 for a set time, the drive motor starts, the feeding sleeve rotates, and the feeding sleeve drives the material tray to rotate, so that the next empty support module rotates to the front of the detection housing 10138, the drive motor stops, and then continues to complete the feeding of the next support module.

[0056] Reference Figures 2-5 and Figures 9-13 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment and can adjust the distance between the first discharge rod 10113 and the second discharge rod 10112 according to the size of the piston ring, thereby improving the applicability.

[0057] Specifically, the feeding assembly 101 also includes a support block 1014 fixedly connected to the upper side of the material tray. A first moving plate 1017 is fixedly connected to the end of the first support plate 10118 away from the second magnet 10116. A second moving plate 1019, which is disposed opposite to the first moving plate 1017, is fixedly connected to the second support plate 10111. A first moving nut 1012 and a second moving nut 1018 are fixedly connected to the first moving plate 1017 and the second moving plate 1019, respectively. A feeding screw 1016 is rotatably connected to the support block 1014. A rotating handle 1013 is fixedly connected to the end of the feeding screw 1016 that extends out of the support block 1014. The first moving nut 1012 and the second moving nut 1018 are both threadedly connected to the feeding screw 1016.

[0058] When storing piston rings of a different specification, hold the rotating handle 1013 and rotate it. The feeding screw 1016 rotates, which in turn drives the first moving nut 1012 and the second moving nut 1018 to move. The first moving nut 1012 drives the first support plate 10118 to move via the first moving plate 1017. The second moving nut 1018 drives the second support plate 10111 to move via the second moving plate 1019. The first support plate 10118 and the second support plate 10111 drive the first feeding rod 10113 and the second feeding rod 10112 to move. When the distance between the first feeding rod 10113 and the second feeding rod 10112 corresponds to the outer diameter of the piston ring, stop rotating the rotating handle 1013. This method is suitable for loading and unloading piston rings of different specifications and sizes.

[0059] Example 3

[0060] Reference Figure 12 and Figure 13 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments and can realize the loading before honing, honing, cleaning and unloading after honing.

[0061] Specifically, it also includes a robotic arm 400, with honing machines 300 on its left and right sides respectively. A hopper 100 is located in front of the robotic arm 400, and a cleaning machine 200 for cleaning piston rings is located behind the robotic arm 400. An adapter frame 405 is rotatably connected to the upper end of the robotic arm 400. A gripping motor 406 is fixedly connected to the outside of the adapter frame 405. A first clamping screw 404 is rotatably connected to the adapter frame 405. The gripping motor 406 and the first clamping screw 404 are connected by transmission. A first slider 401 and a second slider are threadedly connected to the first clamping screw 404 and slidably connected to the adapter frame 405. A first sliding plate 402 and a second sliding plate are fixedly connected to the upper sides of the first slider 401 and the second sliding plate respectively. The first sliding plate 402 and the second sliding plate can move towards or away from each other. A first gripper 407 is fixedly connected to both ends of the first sliding plate 402 in the length direction, and a second gripper 403 is fixedly connected to both ends of the second sliding plate in the length direction.

[0062] The robotic arm 400 removes the top piston ring from the loading station and places it into the left honing machine 300. The left honing machine 300 hones the piston ring. Simultaneously, the lifting motor 10127 continues to operate, causing the pusher plate 10143 to move upwards. When the lifting unloading plate 10115 pushes the top piston ring to a set height, the lifting motor 10127 stops. At the same time, the robotic arm 400 grabs the top piston ring again and places it into the right honing machine 300. Through these steps, the loading of both the left and right honing machines 300 is completed. After the left honing machine 300 finishes honing, the honed piston ring is ejected. The first gripper 407 and the second gripper 403 of the robotic arm 400 clamp the honed piston ring, and the robotic arm 400 moves the clamped piston ring to the loading station of the cleaning machine 200. When motor 406 is activated, the first clamping screw 404 rotates, causing the first slider 401 and the second slider to move in opposite directions, releasing the piston ring. The gripping motor 406 stops operating, and the robot arm 400 then performs the next transfer action. The cleaning machine 200 cleans the piston ring, and the robot arm 400 then sends a new piston ring from the loading assembly 101 into the honing machine 300 on the left. The robot arm 400 rotates to the discharge station of the honing machine 300 on the right, clamps the piston ring, and transfers it to the loading station of the cleaning machine 200. After cleaning, the cleaned piston ring rotates to the unloading station of the cleaning machine 200, causing the adapter 405 to rotate to a set angle. The adapter 405 stops rotating, and the first gripper 407 and the second gripper 403 at the other end clamp the cleaned piston ring, transferring it to the unloading station in the unloading assembly 102.

[0063] Example 4

[0064] Reference Figure 12 and Figure 13 This is the third embodiment of the present invention, which is based on embodiment 3 and can further realize the feeding and discharging before and after honing, as well as the cleaning of piston rings after honing.

[0065] Specifically, the honing machine 300 includes a honing machine frame 301, on which a honing head 302 is connected. At the front and rear ends of the honing machine frame 301, a feeding module 303 and a discharging module 304 with identical structures and oppositely arranged are respectively connected. The feeding module 303 is located behind the discharging module 304. The feeding module 303 includes a material rack 3038 fixedly connected to the honing machine frame 301. A connecting column 3032 is fixedly connected to the honing machine frame 301 between the honing head 302 and the material rack 3038. A cross-shaped material plate 3034 for placing piston rings is fixedly connected to the upper side of the connecting column 3032. A horizontally arranged horizontal lead screw 30316 is rotatably connected to the material rack 3038. The outer side of the material rack 3038... A feed motor 30317 is fixedly connected, and the feed motor 30317 is driven by a horizontal lead screw 30316. A feed nut 30318 is threaded onto the first horizontal lead screw 30316. A movable frame 3039, which is slidably connected to the feed nut 30318, is fixedly connected to the feed nut 30318. A feed support plate 30319, which can reciprocate linearly in the height direction, is connected to the movable frame 3039. A lifting driver 30320, preferably a cylinder, is fixedly connected to the movable frame 3039. A lifting rod 30321, which can reciprocate linearly in the height direction, is connected to the lifting driver 30321. A push-pull block 3032 is fixedly connected to the upper end of the lifting rod 30321. 2. The push-pull block 30322 is connected to the infeed / outfeed support plate 30319. Several lifting guide rods 30312 are arranged on the moving frame 3039. Several lifting guide sleeves 30313, corresponding one-to-one with the lifting guide rods 30312, are arranged on the infeed / outfeed support plate 30319. The lifting guide sleeves 30313 can slide up and down along their corresponding lifting guide rods 30312. A second clamping screw 30314 is rotatably connected to the infeed / outfeed support plate 30319. A clamping motor 30311 is fixedly connected to the infeed / outfeed support plate 30319. The clamping motor 30311 and the second clamping screw 30314 are connected by a transmission. A first clamping nut 30315 and a second clamping nut 30315 that move in opposite directions are threaded onto the second clamping screw 30314. A clamping nut 30310, a first clamping nut 30315, and a second clamping nut 30310 are respectively fixedly connected to a first connecting block 3031 and a second connecting block 3037 that are slidably connected to the infeed / outfeed support plate 30319. A first clamping plate 3033 and a second clamping plate 3036 are respectively fixedly connected to the ends of the first connecting block 3031 and the second connecting block 3037 that are far apart from each other. A first gripper is connected to the end of the first clamping plate 3033 opposite to the second clamping plate 3036, and a second gripper is connected to the end of the second clamping plate 3036 opposite to the first clamping plate 3033. The first and second grippers have the same structure. The grippers in the feeding module 303 and the discharging module 304 have different structures. For ease of description...The first and second grippers in the feeding module 303 are defined as feeding grippers 3035. Several clamping grooves X are arranged at the downward-facing end of the feeding grippers 3035. When the feeding grippers 3035 move above the material placement plate 3034, they descend, and the feeding grippers 3035 on the upper side of the clamping grooves X abut against the material placement plate 3034. When the two feeding grippers 3035 move towards each other, they slide along the material placement plate 3034 via the clamping grooves X. When the two feeding grippers 3035 are together, they clamp the piston rings before honing. The first and second grippers in the discharging module 304 are defined as discharging grippers, and the opposite sides of the two discharging grippers are V-shaped.

[0066] In the initial state, the moving frame 3039 in the feeding module 303 is at the rear of the honing machine frame 301, and the moving frame 3039 in the discharging module 304 is at the front of the honing machine frame 301. Before honing, the robot arm 400 moves the piston ring at the loading station to the rear placement plate 3034. The feeding / discharging motor 30317 is activated, the horizontal lead screw 30316 rotates, and the feeding / discharging nut 30318 drives the moving frame 3039 to move, causing the moving frame 3039 to move towards the placement plate 3034. When the feeding gripper 3035 moves to the position above the placement plate 3034, the feeding / discharging... When the feeding motor 30317 stops operating, the lifting driver 30320 is activated, causing the lifting rod 30321 to descend. The lifting rod 30321 then moves the infeed / outfeed support plate 30319 downwards. When the feeding gripper 3035 contacts the material placement plate 3034, the lifting driver 30320 stops operating, the clamping motor 30311 activates, the second clamping screw 30314 rotates, and the first clamping nut 30315 and the second clamping nut 30310 move. The direction of the clamping motor 30311 is controlled so that the first clamping nut 30315 and the second clamping nut 30310 move towards each other. When the first clamping nut 30315 moves via the first connecting block 3031, the first clamping hand moves, and the second clamping nut 30310 moves via the second connecting block, the second clamping hand moves, and the two feeding clamps 3035 move towards each other. When the two feeding clamps 3035 are in contact, they completely clamp the piston ring. The lifting drive 30320 reverses its movement, the lifting rod 30321 moves up to the set position, the piston ring leaves the material placement plate 3034, the lifting drive 30320 stops, and the feeding motor 30317 actuates, causing the moving frame 3039 to move towards the honing head 302. When the piston ring moves to the honing station below the honing head 302, the feeding motor 30317 stops, the clamping motor 30311 reverses, the two feeding grippers release the piston ring, and the piston ring falls into the honing station. The honing machine 300 hones the piston ring. After honing, the piston ring is ejected and clamped by the discharge module 304. The honed piston ring is then placed on the front placement plate 3034 by the discharge module 304. The robot arm 400 then clamps the piston ring on the front placement plate 3034, preparing to transfer it to the loading station of the cleaning machine 200.

[0067] The cleaning machine 200 includes a cleaning frame 201 with a cleaning tank. A gearbox 203 is fixedly connected to the upper side of the cleaning frame 201. A cleaning loading / unloading motor 205 is fixedly connected to the gearbox 203. An output shaft is connected to the gearbox 203. The cleaning loading / unloading motor 205 and the output shaft are connected in a driving connection. A rotating connecting plate 202 is connected to the output shaft. Detection ports 202a are arranged on the rotating connecting plate 202. A mounting block 208 is fixedly connected to the rotating connecting plate 202 near the detection ports 202a. A suspension rod 206 for suspending piston rings is fixedly connected to the side of the mounting block 208 away from the rotating connecting plate 202. A baffle 207 extending toward the center of the rotating connecting plate 202 is fixedly connected to the end of the suspension rod 206 away from the rotating connecting plate 202. When the suspension rod 206 is above the cleaning frame 201, the baffle 207 faces downward relative to the suspension rod 206. When the suspension rod 206 is inside the cleaning tank, the baffle 207 faces upward relative to the suspension rod 206. When the piston ring is driven into the cleaning tank, the piston ring will not slip out of the suspension rod 206 due to the blocking effect of the baffle 207, further improving the reliability of the cleaning output. A photoelectric switch 204 is fixedly connected to the outside of the gearbox 203. The photoelectric switch 204 can be aligned with any detection port 202a.

[0068] The suspension rod 206 above the cleaning machine 200 and close to the photoelectric switch 204 is the loading station. At this time, the photoelectric switch 204 is aligned with the detection port 202a on one side of the suspension rod 206. The position of the suspension rod 206 above the cleaning machine 200 and away from the photoelectric switch 204 is the unloading station. In the initial state, the detection port 202a at the loading station is aligned with the photoelectric switch 204. The photoelectric switch 204 detects whether there is an obstruction. The external robot arm 400 moves the honed piston ring to the loading station. The photoelectric switch 204 detects the presence of the piston ring, and the cleaning loading / unloading motor 205 is activated, rotating the connecting... When the receiving plate 202 rotates, the rotating connecting plate 202 drives the piston ring to rotate downward to the set position in the cleaning tank. When the rotating connecting plate 202 stops rotating, the cleaning and unloading motor 205 continues to operate. When it rotates to the unloading station, the first gripper 407 and the second gripper 403 at the other end clamp the cleaned piston ring. The robot arm 400 removes the cleaned piston ring and moves it to the lifting unloading plate 10115 between the first unloading rod 10113 and the second unloading rod 10112 in the unloading assembly 102 to realize the unloading of the cleaned piston ring.

[0070] The directions described in this application are based on the front view, with the direction perpendicular to the paper being the front-back direction.
