Description

Technical Field

[0001] This utility model relates to the field of piston ring processing technology, specifically to an automatic piston ring internal angle chamfering machine. Background Technology

[0002] As a key component of internal combustion engines, the quality of the inner chamfer machining of piston rings directly affects the engine's sealing performance and service life.

[0003] Currently, CNC chamfering machines are widely used in the industry for internal chamfering of piston rings. However, existing equipment suffers from the following technical bottlenecks: low single-piece processing efficiency: traditional equipment adopts a single-station design, which can only clamp and process one piston ring at a time before replacing it with the next workpiece. Taking a four-cylinder engine piston assembly (4 piston rings) as an example, the entire processing process requires repeating the clamping-processing-unloading cycle 4 times, resulting in severely limited production efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing an automatic piston ring internal angle reversing machine.

[0005] The technical solution of this utility model: an automatic piston ring inner angle rewinding machine, comprising:

[0006] The countertop has a rack at its bottom.

[0007] A round tube, which is vertically installed on the table and runs through the table;

[0008] Multiple limiting rings are arranged side by side on a circular tube. A guide post is vertically installed on the edge of the circular tube, and the guide post moves through the multiple limiting rings. A ring-shaped notch is opened on the upper edge of the inner side of the limiting ring. Both ends of the multiple limiting rings are connected to connecting ear plates. A suspension rope is connected between two adjacent connecting ear plates on the same side. A drive assembly for driving the top limiting ring to move is installed on the platform.

[0009] The synchronous cutting mechanism is located inside the circular tube. A support is provided at the bottom end of the circular tube, and the synchronous cutting mechanism is installed on the support. A first servo cylinder for driving the support to move is installed on the table.

[0010] Preferably, the synchronous cutting mechanism includes a first servo motor, a turntable, a second servo motor, and multiple cutting discs. The second servo motor is mounted on a support, the turntable is mounted on the output shaft of the second servo motor, the first servo motor is mounted on the turntable and is offset from the center of the turntable, and a mounting shaft is connected to the rotating shaft of the first servo motor. The multiple cutting discs are all mounted equidistantly on the mounting shaft.

[0011] Preferably, a support ring is provided at the bottom of the turntable, the turntable is rotatably mounted on the support ring, and the support ring is connected to the support.

[0012] Preferably, a chassis is installed on the tabletop, with an opening on the front side of the chassis, and a movable baffle is slidably installed on the front side of the chassis.

[0013] Preferably, the drive assembly includes a second servo cylinder and a lifting rod. The second servo cylinder is installed at the bottom of the platform, the lifting rod moves through the platform, the lower end of the platform is connected to the output shaft of the second servo cylinder, and the upper end of the platform is connected to the upper limit ring.

[0014] Preferably, when the top limiting ring moves upward to the defined position, the distance between two adjacent limiting rings is equal.

[0015] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial technical effects:

[0016] In this technical solution, a suspension rope is used to connect two adjacent limiting rings. The upward drive of the second servo cylinder ensures that the gap between the two adjacent limiting rings remains consistent, which facilitates the placement of piston rings. When the second servo cylinder performs a downward drive operation, it can simultaneously clamp and fix multiple piston rings. In addition, the synchronous cutting mechanism can simultaneously chamfer multiple piston rings, improving the efficiency of operation. Attached Figure Description

[0021] Example 1

[0022] like Figure 1-4As shown, the present invention proposes an automatic piston ring internal angle chamfering machine, which includes a table 4, a round tube 5, a synchronous cutting mechanism, and multiple limiting rings 6.

[0023] A frame 19 is installed at the bottom of the tabletop 4; a round tube 5 is vertically installed on the tabletop 4 and passes through the tabletop 4, the round tube 5 is fixed on the tabletop 4, and the bottom end of the round tube 5 is flush with the ground of the tabletop 4; multiple limiting rings 6 are arranged side by side on the round tube 5, and guide posts 7 are vertically installed on the edge of the round tube 5, the guide posts 7 movably passing through the multiple limiting rings 6; a ring notch 61 is opened on the upper edge of the inner side of the limiting ring 6; both ends of the multiple limiting rings 6 are connected to connecting ear plates 14, and two adjacent to each other on the same side are connected to each other. A suspension rope 15 is connected between each of the connecting ear plates 14; a drive assembly for moving the top limiting ring 6 is installed on the platform 4. The drive assembly includes a second servo cylinder 17 and a lifting rod 18. The second servo cylinder 17 is installed at the bottom of the platform 4, and the lifting rod 18 moves through the platform 4. The lower end of the platform 4 is connected to the output shaft of the second servo cylinder 17, and the upper end of the platform 4 is connected to the upper limiting ring 6. When the top limiting ring 6 moves upward to the limited position, the distance between two adjacent limiting rings 6 is equal.

[0024] The synchronous cutting mechanism is located inside the circular tube 5. A support 11 is provided at the bottom end of the circular tube 5. The synchronous cutting mechanism is installed on the support 11. A first servo cylinder 16 for driving the support 11 to move is installed on the table 4.

[0025] In this invention, before chamfering the piston ring, the piston ring must first be fixed. The second servo cylinder 17 is activated to drive the uppermost limiting ring 6 to move upward. When the suspension rope 15 connecting the upper limiting ring 6 and the second limiting ring 6 is taut, the upper limiting ring 6 moves continuously, which in turn drives the second limiting ring 6 to move. When the upper limiting ring 6 moves to the specified position, the distance between the two adjacent limiting rings 6 is equal. The gap formed between the two adjacent limiting rings 6 allows the piston ring to pass through and be placed on the corresponding limiting ring 6.

[0026] Multiple piston rings to be processed are placed sequentially on multiple limiting rings 6. It should be noted that, in the initial state, the synchronous cutting mechanism is located at the inner center of the limiting ring 6, and the position of the annular notch 61 is used to place the piston rings. The placed piston rings extend beyond the inner position of the limiting ring 6.

[0027] After multiple piston rings are placed inside the corresponding annular notch 61, the upper limiting ring 6 is driven to move downward by the second servo cylinder 17. It is worth noting that no piston ring to be processed is placed on the uppermost limiting ring 6. The downward movement of the limiting ring 6 causes multiple limiting rings 6 to stack together, and each limiting ring 6 presses and fixes the piston ring at its lower end. Finally, the piston ring can be chamfered by the synchronous cutting mechanism.

[0028] In summary, this technical solution uses a suspension rope 15 to connect two adjacent limiting rings 6. The upward drive of the second servo cylinder 17 ensures that the gap between the two adjacent limiting rings 6 remains consistent, which facilitates the placement of piston rings. When the second servo cylinder 17 performs a downward drive operation, it can synchronously clamp and fix multiple piston rings, resulting in high operating efficiency.

[0029] Example 2

[0030] like Figure 3 As shown, the present invention proposes an automatic piston ring chamfering machine. Compared with Embodiment 1, in this embodiment, the synchronous cutting mechanism includes a first servo motor 8, a turntable 9, a second servo motor 12, and multiple cutting discs 13. The second servo motor 12 is mounted on a support 11, the turntable 9 is mounted on the output shaft of the second servo motor 12, the first servo motor 8 is mounted on the turntable 9, and the first servo motor 8 is offset from the center of the turntable 9. A mounting shaft is connected to the rotating shaft of the first servo motor 8, and the multiple cutting discs 13 are all equidistantly mounted on the mounting shaft.

[0031] A support ring 10 is provided at the bottom of the turntable 9. The turntable 9 is rotatably mounted on the support ring 10, and the support ring 10 is connected to the support 11.

[0032] In this invention, when installing piston rings, the notch on the piston ring is passed through the mounting shaft, so that the cutting disc 13 is placed inside the piston ring. During chamfering, the first servo motor 8 is started to drive multiple cutting discs 13 to rotate. Each cutting disc 13 corresponds to one piston ring, enabling synchronous processing of multiple piston rings. Subsequently, the first servo cylinder 16 drives the support 11 to move radially away from the center of the limiting ring 6. When the high-speed rotating cutting disc 13 contacts the upper end of the inner edge of the piston ring, the piston ring is cut. During the cutting process, the second servo motor 12 is started to drive the turntable 9 to rotate, so that the cutting disc 13 rotates around the center of the limiting ring 6, realizing the ring cutting of the piston ring. After the ring cutting is completed, the entire chamfering work is finished. In summary, by driving multiple cutting discs 13, which correspond one-to-one with multiple piston rings, the equipment can complete the synchronous cutting of multiple piston rings, improving the working efficiency of the equipment.

[0033] Example 3

[0034] like Figure 1 and Figure 2 As shown, the present invention proposes an automatic piston ring chamfering machine. Compared with Embodiment 1, in this embodiment, a machine box 1 is provided on the table 4, and the front side of the machine box 1 is open. A movable baffle 2 is slidably installed on the front side of the machine box 1. Furthermore, a PLC controller 3 is installed on the movable baffle 2. After the piston ring fixing work is completed, the movable baffle 2 is slid closed, which can effectively reduce the noise during processing and also prevent cutting debris from splashing outwards. After processing, the debris inside the machine box 1 can be sucked up by a handheld vacuum cleaner.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
