Description

Technical Field

[0001] This invention relates to the field of pipe fitting processing equipment, and in particular to an automatic deburring machine. Background Technology

[0002] As one of the commonly used component shape options, pipe fittings usually require cutting, grinding, polishing and other processes for processing. Current cutting tools and equipment usually cut through the pipe from one side to the other side to break the pipe at the cutting position. However, when the pipe material is soft or the wall thickness is thin, the above cutting method is prone to bending the pipe at the cutting position in the cutting direction to form a flange, which is not conducive to the processing effect of the pipe end.

[0003] Meanwhile, since the existing cutting and grinding are two separate processing steps, two machines are usually needed to process the pipe fittings in two separate processes. This results in a large total equipment footprint and high cost. Furthermore, when calibrating the position of the pipe fittings between the two machines, calibration errors are likely to occur, increasing the probability of pipe fitting processing errors. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic deburring machine that increases the efficiency of pipe cutting and simultaneously removes burrs from the pipe cutting location during the cutting process.

[0005] To solve the above-mentioned technical problems, the present invention provides an automatic deburring machine, including a support base, a movable cutting seat disposed within the support base, a cutting blade disposed on one side of the cutting seat, and grinding discs disposed on both sides of the cutting blade. The support base is arranged in a ring structure, and the cutting seat moves circumferentially along the inner ring of the support base. The pipe is passed through the center position of the support base so that the cutting blade performs circumferential cutting on the pipe.

[0006] Furthermore, the cutting seat is movably provided with an adjustment seat, the cutting blade can rotate relative to the adjustment seat, and when the adjustment seat moves, the direction of movement of the adjustment seat is radial to the support seat.

[0007] Furthermore, at least two drive slots are provided on both sides of the cutting seat, and the drive block is movably disposed in the drive slot. The drive block and the adjusting seat are connected by a connecting rod, and the drive block and the connecting rod are rotatably connected.

[0008] Furthermore, the top of the support base is provided with an oil storage chamber, the bottom of the oil storage chamber is provided with an oil outlet, the cutting base is provided with an oil inlet pipe corresponding to the oil outlet, the adjusting base is provided with an oil inlet groove corresponding to the oil inlet pipe, the port of the oil inlet groove is aligned with the position of the cutting blade, and the oil outlet is provided with a solenoid valve. When the solenoid valve is opened, the lubricating oil in the oil storage chamber flows sequentially along the oil outlet, the oil inlet pipe and the oil inlet groove to the cutting blade.

[0009] Furthermore, the end of the oil inlet pipe near the adjusting seat extends axially along the oil inlet groove, and the outer wall of the oil inlet pipe is attached to the inner wall of the oil inlet groove.

[0010] Furthermore, an oil inlet is provided at the upper part of the oil storage chamber, and a pipe plug is inserted into the oil inlet.

[0011] Furthermore, the bottom of the support base is connected to the fixed base, and the fixed base has a placement position on the side near the support base. The support base is located in the placement position, and fixed plates are connected to both sides of the support base. Fixed slots are opened on both sides of the fixed base, and the fixed plates are inserted into the fixed slots.

[0012] Furthermore, fasteners are installed on both sides of the fixing base, and the fasteners pass through the fixing groove and the fixing plate in sequence.

[0013] Furthermore, slots are provided on both sides of the bottom of the support base, and the chip removal box is inserted into the slots, with the chip removal box placed on both sides of the moving path of the cutting base.

[0014] Furthermore, the inner ring of the support base is provided with a drive rail along the circumference. The cutting seat moves along the drive rail. The protective plate is laid at the opening of the drive rail, and the two ends of the protective plate are respectively connected to the two sides of the cutting seat. The inner ring surface of the protective plate has a conical structure.

[0015] The beneficial effects of this invention are as follows: When pipe fittings need to be cut, the pipe fitting to be processed is passed through the support base, and both ends of the pipe fitting are fixed by an external fixing device, so that the position of the pipe fitting to be cut is stably maintained in the inner circle of the support base. Then, the cutting base is started to drive the cutting blade to move circumferentially along the inner circle of the support base. During the circumferential movement, the cutting blade cuts the position of the pipe fitting to be cut. Since the cutting method adopted by this solution is different from the existing method of cutting through the pipe fitting from one side to the other, the cutting blade will not cause bending or flanging of the pipe fitting during the circumferential cutting process, which increases the efficiency of pipe fitting cutting. At the same time, due to the grinding discs on both sides of the cutting blade, after the cutting blade has cut the pipe fitting, the cutting blade moves towards the pipe fitting, so that the grinding discs move closer to the cutting position of the pipe fitting. Then, the cutting base continues to drive the cutting blade and the grinding discs to move circumferentially, so that the grinding discs grind and remove burrs from the cutting position of the pipe fitting during the movement of the grinding discs, which increases the overall efficiency of cutting and grinding to remove burrs, and effectively reduces the overall footprint and processing cost of the equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] like Figure 1-7The present invention provides an automatic deburring machine, including a support base 1, a movable cutting seat 2 disposed within the support base 1, a cutting blade 3 disposed on one side of the cutting seat 2, and grinding discs 4 disposed on both sides of the cutting blade 3. The support base 1 is arranged in a ring structure, and the cutting seat 2 moves circumferentially along the inner ring of the support base 1. The pipe passes through the center position of the support base 1 so that the cutting blade 3 performs circumferential cutting on the pipe.

[0028] When pipe fittings need to be cut, the pipe fitting to be processed is passed through the support base, and both ends of the pipe fitting are fixed by an external fixing device, so that the position of the pipe fitting to be cut is stably maintained in the inner circle of the support base. Then, the cutting base is started, which drives the cutting blade to move circumferentially along the inner circle of the support base. During the circumferential movement, the cutting blade cuts the position of the pipe fitting to be cut. Since the cutting method adopted by this solution is different from the existing method of cutting through the pipe fitting from one side to the other, the cutting blade will not cause bending or flanging of the pipe fitting during the circumferential cutting process, which improves the cutting efficiency. At the same time, due to the grinding discs on both sides of the cutting blade, after the cutting blade has cut the pipe fitting, the cutting blade moves towards the pipe fitting, so that the grinding discs move closer to the cutting position of the pipe fitting. Then, the cutting base continues to drive the cutting blade and grinding discs to move circumferentially, so that the grinding discs grind and remove burrs from the cutting position of the pipe fitting during the movement, which increases the overall efficiency of cutting and grinding and burr removal, and effectively reduces the overall footprint and processing cost of the equipment.

[0029] The external fixing device used in this solution is usually a pneumatic gripper, which clamps and fixes both ends of the pipe to prevent the pipe from falling down to the cutting position after cutting.

[0030] Preferably, the cutting seat 2 is movably provided with an adjusting seat 5, the cutting blade 3 can rotate relative to the adjusting seat 5, and when the adjusting seat 5 moves, the moving direction of the adjusting seat 5 is radial to the support seat 1.

[0031] Specifically, by setting the adjusting seat, when the cutting blade rotates and cuts relative to the adjusting seat, the adjusting seat moves radially along the support seat, so that the adjusting seat drives the cutting blade to move closer to the pipe to be cut, so that the cutting blade can cut the pipe. At the same time, when the grinding disc grinds the pipe cutting position, the grinding position of the grinding disc is also adjusted by moving the adjusting seat radially relative to the support seat.

[0032] In one embodiment of this solution, the adjusting base has a motor, and the center position of the cutting blade is connected to the output end of the motor so that the motor starts and drives the cutting blade to rotate and cut, or the center positions of the motor and the cutting blade are transmitted through a synchronous belt so that the motor drives the cutting blade to rotate and cut after starting.

[0033] Preferably, the cutting seat 2 has at least two driving grooves 6 on both sides, the driving block 7 is movably disposed in the driving groove 6, and the driving block 7 is connected to the adjusting seat 5 through the connecting rod 8. The driving block 7 and the connecting rod 8 are rotatably connected, and the adjusting seat 5 and the connecting rod 8 are rotatably connected.

[0034] Specifically, when the position of the adjusting seat needs to be moved, the driving block moves along the driving groove, causing the driving block to pull or push the connecting rod, thereby moving the position of the adjusting seat through the connecting rod, so that the adjusting seat moves radially along the support seat. Since there are driving grooves on both sides of the cutting seat, the stability of the adjusting seat during the movement can be guaranteed when the driving blocks on both sides move synchronously.

[0035] In one embodiment of this solution, the drive groove has a telescopic rod on the side away from the cutting seat. The end of the telescopic rod is connected to one side of the drive block. The movement of the drive block is controlled by the extension and retraction of the telescopic rod. At the same time, the telescopic rod is driven by a hydraulic cylinder, a pneumatic cylinder, or an electric push rod.

[0036] Preferably, the support base 1 has an oil storage chamber 9 at the top and an oil outlet 10 at the bottom. The cutting base 2 has an oil inlet pipe 11 corresponding to the oil outlet 10. The adjusting base 5 has an oil inlet groove 12 corresponding to the oil inlet pipe 11. The port of the oil inlet groove 12 is aligned with the position of the cutting blade 3. The oil outlet 10 has a solenoid valve 13. When the solenoid valve 13 is opened, the lubricating oil in the oil storage chamber 9 flows sequentially along the oil outlet 10, the oil inlet pipe 11 and the oil inlet groove 12 to the cutting blade 3.

[0037] Specifically, when adding lubricating oil to the cutting blade and grinding disc, stop the cutting seat at the upper part of the inner ring of the support base. At this time, align the oil outlet with the oil inlet pipe and open the solenoid valve. This allows the lubricating oil in the oil reservoir to flow sequentially along the oil outlet, oil inlet pipe, and oil inlet groove to the cutting blade. Simultaneously, the rotation of the cutting blade ensures that the lubricating oil flows onto the cutting blade and grinding disc, covering the surface of the cutting blade and grinding disc more evenly. This enhances the performance of the cutting blade and grinding disc during use and prevents overheating of parts due to excessive friction.

[0038] Preferably, the end of the oil inlet pipe 11 near the adjusting seat 5 extends along the axial direction of the oil inlet groove 12, and the outer wall of the oil inlet pipe 11 is attached to the inner wall of the oil inlet groove 12.

[0039] Specifically, due to the axial extension of the oil inlet pipe, when the adjusting seat moves relative to the cutting seat, the oil inlet pipe can maintain the connection between the oil inlet pipe and the oil inlet groove through the axially extended oil inlet pipe. At the same time, the cooperation between the oil inlet pipe and the oil inlet groove allows the adjusting seat to be guided by the oil inlet pipe during the movement, increasing the stability of the adjusting seat's movement.

[0040] Preferably, an oil inlet 14 is provided at the upper part of the oil storage chamber 9, and a pipe plug 15 is inserted into the oil inlet 14.

[0041] Specifically, when there is insufficient lubricating oil inside the oil reservoir, the plug is pulled out of the oil inlet position to expose the oil inlet, so that lubricating oil can be injected into the oil reservoir through the oil inlet.

[0042] Preferably, the bottom of the support base 1 is connected to the fixed base 16. The fixed base 16 has a placement position 17 on the side near the support base 1. The support base 1 is located in the placement position 17. Fixed plates 18 are connected to both sides of the support base 1. Fixed grooves 19 are opened on both sides of the fixed base 16. The fixed plates 18 are inserted into the fixed grooves 19.

[0043] Specifically, since the diameter of pipe fittings may vary between different batches, and the current solution has limitations in adjusting the cutting range of the cutting blade and the grinding range of the grinding disc by adjusting the seat, this solution ensures that pipe fittings from different batches can be used normally. Therefore, this solution detachably connects the support seat and the fixed seat. When the diameter of the pipe fitting changes significantly, the original support seat can be completely removed and replaced with a suitable support seat, which is then fixed to the fixed seat. This improves the processing effect and smoothness between different batches of pipe fittings.

[0044] When detachably connecting the support base and the fixed base, align the bottom of the support base with the placement position and place the support base into the placement position for initial fixation. At the same time, insert the fixing plates on both sides of the support base into the fixing grooves so that the fixing plates and fixing grooves cooperate to increase the connection between the support base and the fixed base.

[0045] Preferably, fixing members 20 are provided on both sides of the fixing base 16, and the fixing members 20 are sequentially passed through the fixing groove 19 and the fixing plate 18.

[0046] Specifically, by inserting fasteners through the fixing groove and fixing plate, the fasteners are fixedly connected to the fixing groove and fixing plate, ensuring that the support seat will not detach from the fixing seat during the cutting and grinding process of the pipe fitting.

[0047] In one embodiment of this solution, the fastener is a bolt, and the corresponding positions of the fixing groove and the fixing plate are provided with screw holes. The bolt is passed through and fixed to the corresponding screw holes to complete the fixing operation.

[0048] Preferably, the support base 1 has slots 21 on both sides of its bottom, and the chip removal box 22 is inserted into the slots 21, with the chip removal box 22 placed on both sides of the moving path of the cutting base 2.

[0049] Specifically, when the cutting blade makes a circumferential cut to the pipe fitting, a certain amount of flying debris will be generated at the cut point. At this time, the chip removal box can collect most of the flying debris, avoiding the tedious subsequent collection process. After the chip removal box has collected a certain amount of flying debris, it can be pulled out directly from the slot for easy cleaning.

[0050] Preferably, the inner ring of the support base 1 is provided with a drive rail 23 along the circumference, the cutting base 2 moves along the drive rail 23, the protective plate 24 is laid at the opening of the drive rail 23, and the two ends of the protective plate 24 are respectively connected to the two sides of the cutting base 2, and the inner ring surface of the protective plate 24 has a conical structure.

[0051] Specifically, this solution uses a drive rail to drive the cutting seat circumferentially. Since the inner ring of the drive rail is open, the cutting seat can move along it. To prevent debris from entering the drive rail from the opening and causing it to become stuck, a protective plate is installed at the opening to block the debris. Because the protective plate is connected to both sides of the cutting seat, it moves synchronously with the cutting seat as it moves circumferentially along the drive rail, thus blocking debris and preventing interference between the protective plate and the cutting seat.

[0052] In particular, due to the conical structure on the inner surface of the protective plate, when flying debris splashes onto the inner surface of the protective plate, it is guided by the conical structure, causing the debris to fall to the chip discharge boxes on both sides, thus increasing the combined effect of the protective plate blocking flying debris and the chip discharge boxes collecting flying debris.

[0053] In one embodiment of this solution, the drive rail and the cutting seat are connected by an electric rail transmission structure.

[0054] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
