Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of piston rod cutting, in particular to a piston rod lathe cutting device and process. BACKGROUND

[0002] As the core component of mechanical transmission systems (such as hydraulic cylinders, air cylinders, shock absorbers, etc.), piston rods are widely used in the fields of automobiles, engineering machinery, aerospace, hydraulic equipment, etc., and their machining precision (such as cylindricity, coaxiality, surface finish), dimensional consistency and surface mechanical properties directly determine the sealing, motion stability and service life of the transmission system. When cutting the piston rod, the traditional device will cause the cutting fluid on the surface of the piston rod to be thrown out due to high-speed rotation, which will cause the cutting tool temperature to gradually rise when the cutting time is long, and then cause the cutting tool to be passivated or deformed, affecting the cutting precision of the piston rod. SUMMARY

[0003] In order to solve the technical problems of the existing piston rod lathe cutting device that local overheating or insufficient lubrication is caused by the mismatch between the coverage range of the spray head and the workpiece, and the cutting tool temperature gradually rises when the cutting time is long, and then the cutting tool is passivated or deformed, the present application provides a piston rod lathe cutting device.

[0005] A first electric push rod is installed at one end of the base, the output end of the first electric push rod is connected to the sliding seat, a first rack is fixedly connected to one end of the rotating disc A, the rotating disc A is rotatably connected to the sliding seat, an electric motor is installed at one end of the fixed seat, a rotating rod is connected to the output end of the electric motor, the rotating rod penetrates through the fixed seat and is connected to the rotating disc B at the other end, and the rotating disc B and the rotating disc A are located in the same plane.

[0006] Each of the multiple sets of connecting pipes A has a delivery pipe at the other end, and the other end of the delivery pipe is connected to the liquid storage tank. A first gear is connected to the outside of the delivery pipe, and a valve stem A is connected to the end of the first gear near the delivery pipe. The valve stem A extends through the delivery pipe and into the interior to connect with the shut-off valve A.

[0007] Each of the multiple sets of connecting pipes A is provided with a second gear on one side. The end of the second gear near the connecting pipe A is connected to a valve stem B. The valve stem B extends through the connecting pipe A and into the interior to connect with the shut-off valve B. The first rack meshes with the first gear and the second gear.

[0008] Preferably, a first slide is provided on one side of the fixed base, a second slide is slidably connected to the outside of the first slide, a second electric push rod is connected to one end of the second slide, and the output end of the second electric push rod is connected to the cutter.

[0009] One end of the hose is connected to the fan, and the other end of the hose is connected to the connecting pipe B. The outside of the hose is connected to the branch pipe through a pipe.

[0010] A third gear is provided on one side of the connecting pipe B. A valve stem C is fixedly connected to one end of the third gear near the connecting pipe B. The other end of the valve stem C extends through the connecting pipe B and into the interior to connect with the shut-off valve C. A second rack is connected to one side of the second slide block. The second rack and the third gear are located on the same plane and mesh with each other.

[0011] A push rod is movably connected inside the guide tube. One end of the push rod, located inside the guide tube, is connected to a spring, and the other end of the spring is connected to the inner wall of the guide tube.

[0012] The push rod is connected to a rotor at one end located outside the guide tube, and a drive shaft is connected to the output end of the rotor. The other end of the drive shaft is connected to the grinding disc.

[0013] A piston rod lathe cutting process includes the following steps: Step 1: Place one end of the piston rod to be cut inside the rotating disk B. The other end of the piston rod is pushed by the first electric push rod to move the sliding seat so that the rotating disk A is connected to the other end of the piston rod. At this time, when the rotating disk A moves, it will drive the first rack to move synchronously. When the first rack moves, the shut-off valve A is opened. The position of the rotating disk A will control the number of nozzles to be opened, spraying cutting fluid onto the piston rod. Step 2: During cutting, the fan will deliver gas to the inside of the nozzle through the hose. At this time, the nozzle will deliver the air force to the surface of the piston rod during cutting, which will cool the cutting blade. Step 3: After the cutter moves to the designated position, open the shut-off valve C inside the connecting pipe B. After the shut-off valve C is opened, gas enters the guide pipe and pushes the push rod out. After the push rod is pushed out, the grinding disc contacts the cutter and grinds the cutter. After the push rod is pushed out, the airflow entering the guide pipe blows air onto the grinding disc through the branch pipe.

[0014] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, for piston rods of different lengths, only the corresponding area of ​​the nozzle is activated to ensure that the cutting part receives sufficient cooling and lubrication. This avoids localized overheating or insufficient lubrication caused by a mismatch between the nozzle coverage area and the workpiece, improving machining accuracy and surface quality. Simultaneously, it reduces cutting fluid consumption, lowers production costs, and also reduces subsequent waste fluid disposal. When using the equipment, the fan is simultaneously turned on, allowing some of the cutting fluid to be retained on the piston rod surface by airflow. This reduces the amount of cutting fluid excessively ejected by centrifugal force, helping more cutting fluid remain on the piston rod surface, extending the cutting fluid's contact time in the machining area, prolonging the cooling and lubrication effect, and preventing waste caused by cutting fluid being ejected too quickly. While ensuring effective cooling and lubrication, this reduces cutting fluid consumption and lowers operating costs. When the cutter overheats, the grinding disc moves and rotates synchronously to grind its edge, which can promptly remove burrs and dulling parts caused by high temperature, restore the sharpness of the cutter, and prevent the decrease in processing accuracy caused by cutter wear. At the same time, the branch pipe blows air synchronously after the grinding disc grinds, which directly removes the heat from the surface of the cutter, alleviating the risk of softening and chipping of the cutting edge caused by overheating. On the other hand, it reduces the damage of high temperature to the contact area between the grinding disc and the cutter in conjunction with the grinding process, ensuring the stability of both.

[0024] The technical solutions of the present invention will now be described with reference to the accompanying drawings. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art can use other alternative methods to implement some well-known technologies. Furthermore, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit the present invention.

[0025] Reference Figures 1-8 An embodiment of the present invention provides a piston rod lathe cutting device, including a base 1, a sliding seat 3 slidingly attached to the upper end of the base 1, a rotating disk A4 rotatably attached to one end of the sliding seat 3, a fixed seat 5 disposed on one side of the sliding seat 3, a rotating disk B8 rotatably attached to one end of the fixed seat 5 near the rotating disk A4, and multiple sets of nozzles 10 mounted on the upper end of the fixed seat 5 via a fixing frame 9, with one end of each set of nozzles 10 connected to a connecting pipe A11, and a shut-off valve B disposed inside the connecting pipe A11.

[0026] A second slide block 18 slides on one side of the fixed base 5. A cutter 20 slides on the upper end of the second slide block 18. A guide tube 21 is connected to one side of the second slide block 18. A grinding disc 25 rotates at one end of the guide tube 21. The grinding disc 25 moves horizontally through the guide tube 21. A branch pipe 31 is connected to the outside of the guide tube 21. A connecting pipe B26 is connected to one end of the guide tube 21. A shut-off valve C is installed inside the connecting pipe B26.

[0027] One end of the connecting pipe B26 is connected to a flexible hose 28, and multiple branch pipes 31 are connected to the outside of the flexible hose 28.

[0028] The beneficial effects of the technical solutions provided in the embodiments of the present invention include at least the following: In this embodiment of the invention, for piston rods of different lengths, only the corresponding area of ​​the nozzle is activated to ensure that the cutting part receives sufficient cooling and lubrication. This avoids localized overheating or insufficient lubrication caused by a mismatch between the nozzle coverage area and the workpiece, improving machining accuracy and surface quality. Simultaneously, it reduces cutting fluid consumption, lowers production costs, and also reduces subsequent waste fluid disposal. When using the equipment, the fan is simultaneously turned on, allowing some of the cutting fluid to be retained on the piston rod surface by airflow. This reduces the amount of cutting fluid excessively ejected by centrifugal force, helping more cutting fluid remain on the piston rod surface, extending the cutting fluid's contact time in the machining area, prolonging the cooling and lubrication effect, and preventing waste caused by cutting fluid being ejected too quickly. While ensuring effective cooling and lubrication, this reduces cutting fluid consumption and lowers operating costs. When the cutting tool overheats, the grinding disc moves and rotates synchronously to grind its edge. This promptly removes burrs and dulling caused by high temperatures, restoring the cutting tool's sharpness and preventing a decrease in machining accuracy due to tool wear. Simultaneously, the branch pipe blows air after the grinding disc finishes grinding, directly removing heat from the cutting tool surface and mitigating the risk of softening and chipping due to overheating. Furthermore, this, combined with the grinding process, reduces damage to the contact area between the grinding disc and the cutting tool caused by high temperatures, ensuring the stability of both.

[0029] In one possible implementation, a first electric actuator 2 is installed at one end of the base 1, and the output end of the first electric actuator 2 is connected to the sliding seat 3. A first rack 15 is fixedly connected to one end of the rotating disk A4, and the rotating disk A4 is rotatably connected to the sliding seat 3. A motor 6 is installed at one end of the fixed seat 5, and a rotating rod 7 is connected to the output end of the motor 6. The other end of the rotating rod 7 passes through the fixed seat 5 and is connected to the rotating disk B8. The rotating disk B8 and the rotating disk A4 are located on the same plane. When using the equipment, one end of the piston rod is fixed inside the rotating disk B8. After the piston rod is fixed, the sliding seat 3 is moved by the first electric actuator 2. When the sliding seat 3 moves, the rotating disk A4 contacts the other end of the piston rod, thereby fixing the piston rod. After the piston rod is fixed, the rotating rod 7 is driven to rotate by the motor 6. When the rotating rod 7 rotates, it will synchronously drive the rotating disk B8 to rotate. When the rotating disk B8 rotates, it will synchronously drive the piston rod to rotate.

[0030] In one possible implementation, the other end of each of the multiple sets of connecting pipes A11 is connected to a delivery pipe 12, and the other end of the delivery pipe 12 is connected to a storage tank. A first gear 13 is connected to the outside of the delivery pipe 12, and a valve stem A is connected to the end of the first gear 13 near the delivery pipe 12. The valve stem A extends through the delivery pipe 12 and into the interior to connect with a shut-off valve A. The storage tank contains cutting fluid. As described above, when the rotating disk A4 moves, it will synchronously drive the first rack 15 to move synchronously. When the first rack 15 moves, it will first contact the first gear 13. When the first rack 15 contacts the first gear 13, the first rack 15 will drive the first gear 13 to rotate. When the first gear 13 rotates, it will open the shut-off valve A through the valve stem A. After the shut-off valve A is opened, the cutting fluid will enter the interior of the delivery pipe 12.

[0031] In one possible implementation, a second gear 16 is provided on one side of each of the multiple sets of connecting pipes A11. A valve stem B is connected to the end of the second gear 16 near the connecting pipe A11. The valve stem B extends through the connecting pipe A11 and connects to the shut-off valve B. A first rack 15 meshes with the first gear 13 and the second gear 16. As the rotating disk A4 moves, the first rack 15 will contact the second gear 16 during its travel. After contact, the second gear 16 will rotate. When the second gear 16 rotates, it will close the connecting pipe A11 via the valve stem B. The internal shut-off valve B prevents cutting fluid from entering the nozzle 10 through the connecting pipe A11. Because the distance the rotating disk A4 moves matches the length of the piston rod, closing part of the shut-off valve B will cause multiple sets of nozzles 10 to control the number of sprays according to the length of the piston rod. Thus, for piston rods of different lengths, only the corresponding area of ​​the nozzle 10 is activated, ensuring that the cutting part is adequately cooled and lubricated. This avoids local overheating or insufficient lubrication caused by the mismatch between the coverage area of ​​the nozzle 10 and the workpiece, improving machining accuracy and surface quality. At the same time, it reduces the consumption of cutting fluid, lowers production costs, and also reduces the amount of waste fluid to be disposed of.

[0032] In one possible implementation, a first slide 17 is provided on one side of the fixed base 5, and a second slide 18 is slidably connected to the outside of the first slide 17. A second electric push rod 19 is connected to one end of the second slide 18, and the output end of the second electric push rod 19 is connected to the cutter 20. During cutting, the second slide 18 slides on the first slide 17. After the second slide 18 slides to the designated position, the cutter 20 is pushed out by the second electric push rod 19, so that the cutter 20 contacts the high-speed rotating piston rod, thereby cutting the piston rod.

[0033] In one possible implementation, one end of the hose 28 is connected to the fan, and the other end of the hose 28 is connected to the connecting pipe B26. The outside of the hose 28 is connected to the branch pipe 31 through a pipe. When the equipment is in use, the fan is turned on simultaneously. After the fan is turned on, airflow enters the hose 28. Since the shut-off valve C is initially closed, the airflow cannot enter the connecting pipe B26. Therefore, the airflow enters the branch pipe 31 through the pipe and is discharged outwards. When the branch pipe 31 discharges air, it blows the airflow onto the surface of the piston rod. Due to the rotation of the piston rod and the flow of air through the guide pipe 21... With the airflow coming from opposite directions, convection occurs when the airflow reaches the piston rod surface. As the cutting fluid adheres to the piston rod surface, the high-speed rotation of the piston rod generates centrifugal force, throwing the cutting fluid outwards. This convection, generated by the airflow, applies pressure to the cutting fluid adhering to the piston rod surface, thus retaining some of the cutting fluid on the piston rod surface. This reduces excessive fluid ejection due to centrifugal force, allowing more cutting fluid to remain on the piston rod surface, extending the cutting fluid's contact time in the machining area, prolonging cooling and lubrication effects, and preventing waste caused by excessively rapid ejection of cutting fluid. While ensuring effective cooling and lubrication, this reduces cutting fluid consumption and lowers operating costs.

[0034] In one possible implementation, a third gear 27 is provided on one side of the connecting pipe B26. A valve stem C is fixedly connected to one end of the third gear 27 near the connecting pipe B26, and the other end of the valve stem C extends through the connecting pipe B26 to connect with a shut-off valve C. A second rack 29 is connected to one side of the second slide 18. The second rack 29 and the third gear 27 are located on the same plane and mesh with each other. During cutting, as the second slide 18 moves, it synchronously drives the guide pipe 21 to move. After the guide pipe 21 moves to a certain position, the third gear 27 contacts the second rack 29. When rack 29 contacts the third gear 27, the third gear 27 will rotate. When the third gear 27 rotates, it will synchronously drive the valve stem C to rotate. When the valve stem C rotates, it will open the shut-off valve C inside the connecting pipe B26. In the initial state, the distance between the second rack 29 and the third gear 27 is relatively far. Therefore, when the third gear 27 contacts the second rack 29, it means that the cutting time of the cutter 20 is relatively long, causing the cutter 20 to continuously bear the cutting force and high temperature, which is prone to tool wear or thermal deformation. This will cause obvious tool marks or burrs to be produced on the piston rod surface during cutting. At this time, the shut-off valve C is opened, allowing gas to enter the connecting pipe B26.

[0035] In one possible implementation, a push rod 22 is movably connected inside the guide tube 21. One end of the push rod 22 inside the guide tube 21 is connected to a spring, and the other end of the spring is connected to the inner wall of the guide tube 21. As described above, after the gas enters the connecting tube B26, the connecting tube B26 will transport the gas to the guide tube 21. After the gas enters the guide tube 21, it will push the push rod 22 outward. After the cutting is completed, as the second slide 18 resets, the connecting tube B26 will contact the second rack 29 again, and then the connecting tube B26 will rotate again. When the connecting tube B26 rotates again, the shut-off valve C inside the connecting tube B26 will be closed. At this time, the push rod 22 will gradually reset by the force of the spring.

[0036] In one possible implementation, the push rod 22 is connected to a rotor 23 at one end outside the guide tube 21. The output end of the rotor 23 is connected to a drive shaft 24, and the other end of the drive shaft 24 is connected to a grinding disc 25. As described above, when gas enters the guide tube 21 and pushes the push rod 22 out, it simultaneously moves the push rod 22. When the push rod 22 moves, it simultaneously moves the rotor 23. When the rotor 23 moves, it simultaneously moves the grinding disc 25, causing it to contact the cutter 20. The rotor 23, through the drive shaft 24, simultaneously drives the grinding disc 25 to rotate. When the grinding disc 25 contacts the cutter 20, it grinds the edge of the cutter 20 when it overheats. After the push rod 22 is fully extended, it moves to the other end, at which point it enters the guide tube 21. The internal gas is discharged outward through the branch pipe 31, and the output end of the branch pipe 31 is located on one side of the grinding disc 25. When the branch pipe 31 blows air, it removes the debris generated by the grinding disc 25 during the grinding of the cutter 20, and cools the cutter 20. Thus, when the cutter 20 overheats, the grinding disc 25 moves and rotates synchronously to grind its edge, which can promptly remove the burrs and dulling parts caused by high temperature, restore the sharpness of the cutter 20, and prevent the decrease in machining accuracy caused by the wear of the cutter 20. At the same time, the branch pipe 31 blows air synchronously after the grinding disc 25 grinds, which directly removes the heat from the surface of the cutter 20, alleviating the risk of softening and chipping of the cutting edge caused by overheating. On the other hand, it works in conjunction with the grinding process to reduce the damage of high temperature to the contact area between the grinding disc 25 and the cutter 20, ensuring the stability of both.

[0037] If, during use, the cutter 20 is only used to grind both ends of the piston rod, causing the connecting pipe B26 to contact the second rack 29 in advance, the grinding disc 25 will grind the unheated cutter 20. This will also grind the cutter 20 during normal use, thus ensuring its sharpness and improving processing accuracy and quality. Furthermore, when the gas entering the guide pipe 21 is discharged through the branch pipe 31, due to the small diameter of the branch pipe 31, the gas inside the hose 28 cannot be completely discharged through the branch pipe 31. At this time, a certain pressure will accumulate inside the hose 28, allowing the gas to smoothly enter the nozzle 30 due to the pressure.

[0038] A piston rod lathe cutting process includes the following steps: Step 1: Place one end of the piston rod to be cut inside the rotating disk B8. The other end of the piston rod is moved by the first electric push rod 2 to push the sliding seat 3 to connect the rotating disk A4 with the other end of the piston rod. At this time, when the rotating disk A4 moves, it will drive the first rack 15 to move synchronously. When the first rack 15 moves, the shut-off valve A is opened. The position of the rotating disk A4 will control the number of nozzles 10 that are opened, spraying cutting fluid onto the piston rod.

[0039] Step 2: During cutting, the fan will deliver gas to the inside of the nozzle 30 through the hose 28. At this time, the nozzle 30 will deliver the air force to the surface of the piston rod during cutting, forming convection and cooling the cutter 20 during cutting.

[0040] Step 3: After the cutter 20 moves to the designated position, open the shut-off valve C inside the connecting pipe B26. After the shut-off valve C is opened, gas enters the guide pipe 21 and pushes the push rod 22 out. After the push rod 22 is pushed out, the grinding disc 25 contacts the cutter 20 and grinds the cutter 20. After the push rod 22 is pushed out, the airflow entering the guide pipe 21 blows air onto the grinding disc 25 through the branch pipe 31.
