Description

Technical Field

[0001] The present invention relates to the technical field of piston ring detection, and in particular to an apparatus for on-line automatic detection of the ring height of a piston ring. Background Art

[0002] The piston ring is one of the key components of an engine. It is interconnected with the piston and the cylinder liner to form the engine power source assembly. The piston ring has functions such as sealing, regulating engine oil (oil control), heat conduction (heat transfer), and guiding (supporting). With the development of internal combustion engines towards high-intensity, low-emission, and long-life directions, the requirements for the quality of piston rings are getting higher and higher. It is not only required that the piston ring has high reliability and economy, but more importantly, it should have the best performance. Therefore, during the production process of piston rings, in order to measure and control elements such as the closed gap, radial thickness, light leakage, and ring height of the piston ring to meet the quality requirements.

[0003] When the piston ring is grinding processed, it is ground through two high-speed rotating grinding wheels from above and below. After grinding, the height of the ring depends on the distance between the two grinding wheels, and the feed amount of the grinding wheel is controlled by a feed motor. When the piston ring is being ground, two operators are required. One operator is responsible for feeding materials, and the other operator is responsible for detecting, adjusting, and controlling. The ground piston ring is manually detected, and then the feed handwheel is manually turned according to the measured data by the operator. In addition, a motor drives the handwheel for rapid feeding. There are the following problems: 1. The equipment requires two operators to operate. 2. Manual detection and then adjustment result in a large labor intensity. 3. Manual adjustment depends on experience and there are errors, which have a greater impact on the performance of the piston ring. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an on-line measurement and control mechanism for the end face grinding of a piston ring, which reduces labor, reduces workload, and improves control accuracy.

[0005] The object of the present invention is achieved as follows: An on-line measurement and control mechanism for the end face grinding of piston rings is arranged at the discharge port of a grinding machine tool. The on-line measurement and control mechanism includes a frame panel, on which a primary conveying device arranged left and right is installed. The primary conveying device is used for conveying the ground piston rings. On the frame panel, a secondary conveying device arranged front and back is also installed. The feeding end of the secondary conveying device is arranged on one side in the width direction of the conveyor belt of the primary conveying device, and a ring-taking blowing pipe is arranged on the other side in the width direction of the conveyor belt of the primary conveying device. A ring-taking support is arranged at the feeding end of the secondary conveying device, and a terminal support is arranged at the discharging end. Both the ring-taking support and the terminal support are connected to the frame panel. A ring-pushing lead screw is installed between the ring-taking support and the terminal support. The axial feeding direction of the ring-pushing lead screw is consistent with the conveying direction of the secondary conveying device. One end of the ring-pushing lead screw is connected to a ring-pushing servo motor. A ring-pushing slider is connected to the ring-pushing lead screw, and a ring-pushing cylinder is connected to the ring-pushing slider. The piston rod of the ring-pushing cylinder is arranged downward and connected to a push plate. A measurement support is arranged at the discharging end of the secondary conveying device. The measurement support is installed on the frame panel. A measurement panel is installed on the measurement support. An upper measuring head is arranged above the measurement panel, and a lower measuring head is arranged below. Both the upper measuring head and the lower measuring head are installed on the measurement support. The signal output ends of the upper measuring head and the lower measuring head are both connected to a controller.

[0006] The present invention is installed at the discharge port of the grinding machine tool, and the motor of the handwheel is replaced with a servo motor. During processing, the piston ring passes between the upper and lower grinding wheels of the grinding machine tool for grinding. After grinding, it enters the conveyor belt of the primary conveying device from the discharge port. One piston ring is sampled at time intervals and blown into the conveyor belt of the secondary conveying device through the ring-taking blowing pipe. When it is conveyed to the end of the secondary conveying device, the secondary conveying device stops running. The ring-pushing cylinder extends downward, and the ring-pushing servo motor drives the ring-pushing lead screw to rotate, driving the ring-pushing slider and the ring-pushing cylinder to push towards the measurement panel, thus pushing the piston ring onto the measurement panel. The upper and lower measuring heads detect it and transmit the data to the controller. The controller calculates the feed amount of the grinding wheel based on the measured value and the product control median value, and automatically adjusts it through the servo motor. Therefore, the operator here can be cancelled.

[0007] The beneficial effects of the present invention are as follows: 1. Only one feeding operator is required for the whole equipment, and the operator at the detection, adjustment and control station is cancelled. 2. On-line automatic detection and precise control ensure the performance of the piston ring.

[0008] In the present invention, a left ring-removing stopper and a right ring-removing stopper are installed on the ring-removing bracket. A ring-receiving plate is arranged between the left ring-removing stopper and the right ring-removing stopper, and the ring-receiving plate is arranged directly above the secondary conveying device. The ring-receiving plate is connected to a ring-receiving cylinder, and the ring-receiving cylinder is installed on the measuring bracket. A ring-blocking plate is also arranged between the left ring-removing stopper and the right ring-removing stopper. The upper end of the ring-blocking plate is connected to the ring-removing bracket, and the lower end of the ring-blocking plate is arranged above the ring-receiving plate. The left ring-removing stopper and the right ring-removing stopper can make the piston ring enter a specified position and thus fall onto the ring-receiving plate. When the ring-receiving cylinder retracts, it drives the ring-receiving plate to retreat. Due to the blocking of the ring-blocking plate, the piston ring falls onto the conveyor belt of the secondary conveying device.

[0009] In order to cooperate with piston rings of different diameters, adjusting long holes are arranged on the ring-blocking plate, and the ring-blocking plate is installed on the ring-removing bracket through bolts passing through the adjusting long holes.

[0010] In order to prevent the ring-blowing pipe for ring removal from blowing multiple piston rings into the secondary conveying device, a ring height adjusting device is arranged on the ring-removing bracket. The ring height adjusting device includes a vertically arranged ring height adjusting screw rod, the ring height adjusting screw rod is installed on the ring-removing bracket through a screw rod seat, the upper end of the ring height adjusting screw rod is connected to a ring height adjusting handwheel, a ring height adjusting nut is threadedly connected to the ring height adjusting screw rod, the ring height adjusting nut is connected to a ring height connecting rod, a ring height adjusting rod is connected to the ring height connecting rod, and the ring height adjusting rod is arranged above the conveyor belt of the primary conveying device. A vertically arranged U-shaped guiding hole is arranged on the ring height connecting rod, and a limiting guiding rod is fixedly connected to the ring-removing bracket, and the limiting guiding rod is arranged in the U-shaped guiding hole of the ring height connecting rod. By rotating the handwheel, the ring height adjusting rod moves up and down to control the distance between the ring height adjusting rod and the conveyor belt, ensuring that only one piston ring enters the secondary conveying device each time. In order to ensure that the ring-pushing cylinder moves in a straight line, a ring-pushing guide rail is installed between the ring-removing bracket and the end bracket, and the ring-pushing slider is installed on the ring-pushing guide rail.

[0011] In order to cooperate with piston rings of different diameters and ensure that the piston rings are in the middle position at the end of the conveyor belt of the secondary conveying device, a ring diameter adjusting mechanism is also installed at the output end of the secondary conveying device. The ring diameter adjusting mechanism includes two mounting seats, a double-threaded screw rod, a guide rod, two nuts and two parallel stop blocks; the two mounting seats are both installed on the end bracket, the double-threaded screw rod is threadedly installed on the two mounting seats, one end of the double-threaded screw rod is connected to a handwheel, the double-threaded screw rod is provided with left and right hand threads, one nut is threadedly connected to the right hand thread section of the double-threaded screw rod, and the other nut is threadedly connected to the left hand thread section of the double-threaded screw rod; the guide rod passes through the two nuts and is respectively connected to the corresponding mounting seats at both ends, the two parallel stop blocks are both connected to the corresponding nuts through connecting rods, and the two parallel stop blocks are respectively arranged on the left and right sides above the conveyor belt of the secondary conveying device. Rotate the handwheel, drive the double-threaded screw rod to rotate, drive the nuts to move, and thus drive the two parallel stop blocks to move towards each other or away from each other to adapt to piston rings of different diameters and ensure that the piston rings are in the middle position. In order to ensure the measurement accuracy, a pressing ring bracket is installed above the measurement bracket, the pressing ring bracket is connected to a pressing ring cylinder, the piston rod of the pressing ring cylinder is arranged downward and is connected to a pressing ring block, and the pressing ring block is arranged above the measurement panel. In order to prevent detection errors from occurring when the piston ring is in a free state, after the piston ring reaches the detection position, the piston rod of the pressing ring cylinder extends out, drives the pressing ring block to fix the piston ring on the measurement panel, and the pressing ring cylinder retracts after the detection is completed.

[0012] In the present invention, a ring dropping extension plate is arranged on the side of the measurement panel away from the secondary conveying device, the ring dropping extension plate is connected to the measurement bracket, and a detected ring container is arranged below the ring dropping extension plate, and the detected ring container is installed on the frame panel. The next piston ring pushes the previous piston ring to the extension plate and then falls into the detected ring container.

[0013] In order to avoid the instability of blowing to remove the ring, a blowing and ring-removing in-place sensor is installed on the retaining ring plate; in order to avoid excessive deviation of the stopping position of the ring at the end of the secondary conveying device, a ring-to-conveyor-belt-end sensor is installed on the end bracket.

[0014] In order to detect the position of the piston ring on the measurement panel, a measurement position sensor is installed on the pressing ring bracket. Description of the Drawings

[0024] As shown in Figure 1 -9, the on - line measurement and control mechanism for piston ring end face grinding is arranged at the discharge port of the grinding machine. The on - line measurement and control mechanism includes a frame panel 1 and a controller 36. On the frame panel 1, a primary conveying device 12 and a finished product slide plate 2 are connected. The conveyor belt of the primary conveying device 12 is arranged left - right, and the feeding end is higher than the discharging end, and the slope is matched with the slope of the discharge port of the grinding machine. The primary conveying device 12 is used to convey the ground piston rings, and the finished product slide plate 2 is arranged at the discharging end of the primary conveying device 12.

[0025] On the frame panel 1, a secondary conveying device 14 is also connected. The conveyor belt of the secondary conveying device 14 is arranged front - back and horizontally. The feeding end of the secondary conveying device 14 is arranged on one side in the width direction of the conveyor belt of the primary conveying device 12. On the other side in the width direction of the conveyor belt of the primary conveying device 12, a ring - taking blowing pipe 13 is arranged, and the ring - taking blowing pipe 13 is connected to compressed air.

[0026] At the feeding end of the secondary conveying device 14, a ring - taking support 19 is arranged, and at the discharging end, a terminal support 20 is arranged. Both the ring - taking support 19 and the terminal support 20 are connected to the frame panel 1.

[0027] A ring height adjusting device 11 is provided on the ring removing bracket 19. The ring height adjusting device 11 includes a vertically arranged ring height adjusting lead screw 11-2. The ring height adjusting lead screw 11-2 is connected to the ring removing bracket 19 through a lead screw seat 11-6. The upper end of the ring height adjusting lead screw 11-2 is connected to a ring height adjusting handwheel 11-1. A ring height adjusting nut 11-3 is threadedly connected to the ring height adjusting lead screw 11-2. The ring height adjusting nut 11-3 is connected to a ring height connecting rod 11-4. A ring height adjusting rod 11-5 is connected to the ring height connecting rod 11-4 through a bolt. The ring height adjusting rod 11-5 is arranged above the conveyor belt of the first-stage conveying device 12. The ring height adjusting rod 11-5 is obliquely arranged, and the slope is the same as that of the conveyor belt of the first-stage conveying device 12. A vertically arranged U-shaped guiding hole 11-7 is provided on the ring height connecting rod 11-4. A limiting guiding rod 11-8 is fixedly connected to the ring removing bracket 19. The limiting guiding rod 11-8 is arranged in the U-shaped guiding hole 11-7 of the ring height connecting rod 11-4. During adjustment, rotate the ring height adjusting handwheel 11-1 to drive the rotation of the ring height adjusting lead screw 11-2. Due to the cooperation of the limiting guiding rod 11-8 and the U-shaped guiding hole 11-7, the ring height adjusting nut 11-3 can only move up and down, thereby driving the ring height connecting rod 11-4 and the ring height adjusting rod 11-5 to move up and down, so that the gap between the ring height adjusting rod 11-5 and the conveyor belt of the first-stage conveying device 12 is appropriate, ensuring that only one piston ring passes through.

[0028] A ring removing left stop block 10 and a ring removing right stop block 5 are connected to the ring removing bracket 19. A ring receiving plate 30 is arranged between the ring removing left stop block 10 and the ring removing right stop block 5, and the ring receiving plate 30 is arranged directly above the second-stage conveying device 14. The ring receiving plate 30 is connected to a ring receiving cylinder 33. The retracting direction of the ring receiving cylinder 33 is the same as the conveying direction of the second-stage conveying device 14. The ring receiving cylinder 33 is connected to the measuring bracket 15. A ring blocking plate 31 is also arranged between the ring removing left stop block 10 and the ring removing right stop block 5.

One end of the ring blocking plate 31 is connected to the ring removing bracket 19 through a bolt passing through the adjusting long hole 32. The other end of the ring blocking plate 31 is bent downward and arranged above the ring receiving plate 30. A blowing ring removing in-place sensor 7 is connected to the ring blocking plate 31. The signal output end of the blowing ring removing in-place sensor 7 is connected to the controller 36. When the piston ring moves from the first-stage conveying device 12 to the ring receiving plate 30, the blowing ring removing in-place sensor 7 transmits the detected signal to the controller 36. The controller 36 controls the ring receiving cylinder 33 to retract, driving the ring receiving plate 30 to retreat. Due to the blocking of the ring blocking plate 31, the piston ring falls onto the conveyor belt of the second-stage conveying device 14.

[0029] At the output end of the secondary conveying device 14, a ring diameter adjusting mechanism 3 is further provided. The ring diameter adjusting mechanism 3 includes two mounting seats 3-4, a double-threaded lead screw 3-6, a guide rod 3-7, two nuts 3-5 and two parallel stoppers 3-1.

One nut 3-5 is threadedly connected to the right-handed thread section of the double-threaded lead screw 3-6, and the other nut 3-5 is threadedly connected to the left-handed thread section of the double-threaded lead screw 3-6. The guide rod 3-7 passes through the two nuts 3-5 and is respectively connected to the corresponding mounting seats 3-4 at both ends. The two parallel stoppers 3-1 are both connected to the corresponding nuts 3-5 through connecting rods 3-2. The two parallel stoppers 3-1 are respectively arranged on the left and right sides above the conveyor belt of the secondary conveying device 14. Rotating the handwheel 3-3 drives the double-threaded lead screw 3-6 to rotate, and the two nuts 3-5 move towards each other or away from each other on the guide rod 3-7 to fit piston rings of different diameters, and the piston ring is located at the middle position of the conveyor belt.

[0030] A ring-to-conveyor-belt end sensor 9 is connected to the end bracket 20. The signal output end of the ring-to-conveyor-belt end sensor 9 is connected to a controller 36. A ring-pushing lead screw 6 is connected between the ring-taking bracket 19 and the end bracket 20. The axial feeding direction of the ring-pushing lead screw 6 is the same as the conveying direction of the secondary conveying device 14. One end of the ring-pushing lead screw 6 is connected to a ring-pushing servo motor 22. A ring-pushing slider 18 is connected to the ring-pushing lead screw 6. A ring-pushing cylinder 34 is connected to the ring-pushing slider 18. The piston rod of the ring-pushing cylinder 34 is arranged downward and is connected to a V-shaped pushing plate 35. The opening of the V-shaped pushing plate 35 faces the discharging end of the secondary conveying device 14. A ring-pushing guide rail 16 is connected between the ring-taking bracket 19 and the end bracket 20. The ring-pushing slider 18 is slidably arranged on the ring-pushing guide rail 16. When the piston ring is conveyed to the end of the conveyor belt of the secondary conveying device 14, the conveyor-belt end sensor 9 transmits the detected signal to the controller, and the controller controls the secondary conveying device 14 to stop running. The ring-pushing cylinder 34 pushes the piston ring downward and forward to push the piston ring onto the measuring panel 29.

[0031] A measuring bracket 15 is arranged at the discharging end of the secondary conveying device 14. The measuring bracket 15 is connected to the frame panel 1. A measuring panel 29 is connected to the measuring bracket 15. An upper measuring head 21 is arranged above the measuring panel 29, and a lower measuring head 27 is arranged below the measuring panel 29. The upper measuring head 21 is connected to the measuring bracket 15 through an upper measuring head mounting seat 23. The lower measuring head 27 is connected to the measuring bracket 15 through a lower measuring head mounting seat 17. The signal output ends of the upper measuring head 21 and the lower measuring head 27 are both connected to the controller 36.

[0032] Above the measuring bracket 15, a pressing ring bracket 4 is connected. The pressing ring bracket 4 is connected to a pressing ring cylinder 8.

A measuring position sensor 24 is connected to the pressing ring bracket 4, and the signal transmission end of the measuring position sensor 24 is connected to a controller 36. When the piston ring is pushed by the V-shaped push plate 35 onto the measuring panel 29, the measuring position sensor 24 transmits a signal to the controller. The pressing ring cylinder 8 extends, driving the pressing ring block 25 to act and fixing the piston ring on the measuring panel 29. The upper measuring head 21 and the lower measuring head 27 measure the height of the piston ring and transmit the measurement data to the controller 36. The controller 36 controls the feed amount of the feed motor (servo motor) of the grinding wheel of the grinding machine and automatically adjusts it.

[0033] A ring dropping extension plate 26 is arranged on one side of the measuring panel 29 away from the secondary conveying device 14. The ring dropping extension plate 26 is connected to the measuring bracket 15. Below the ring dropping extension plate 26, a detected ring container 28 is arranged. The detected ring container 28 is connected to the frame panel 1. After the detection is completed, the pressing ring cylinder 8 retracts. The next piston ring pushes the previous piston ring onto the ring dropping extension plate 26 and then drops into the detected ring container 28.

[0034] The function of the present invention is to sample and select a ring from the conveyor belt at time intervals and send it into the detection mechanism for detection. While displaying the detection result, it is compared with the reference value. If there is a difference, the servo motor is used to control the feed of the grinding wheel to improve the control accuracy. The whole process no longer requires manual intervention, thus canceling the operator at this station and playing a role in changing the original two operators into one operator.
