Description

Technical Field

[0001] This utility model relates to the field of workpiece processing technology, and in particular to a workpiece deburring device. Background Technology

[0002] Burrs often form at the ends of metal pipes, which are irregular metal fragments or protrusions remaining at the pipe opening edges.

[0003] The presence of these burrs not only affects the subsequent use of the pipes, but may also bring a series of problems: on the one hand, burrs can lead to assembly difficulties, poor connection sealing, and even damage to mating parts; on the other hand, burrs are sharp and can easily scratch operators, posing a significant safety hazard.

[0004] Publication (Announcement) No.: CN104551912A discloses a steel pipe deburring machine. Although the device can remove burrs from the ends of metal pipes, its efficiency is too low. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low efficiency in removing burrs from the ends of metal tubes as mentioned in the background art, and to propose a workpiece deburring device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A deburring device for removing burrs from both ends of a metal tube includes a conveyor capable of intermittent movement and a power mechanism. The conveyor belt of the conveyor is provided with spaced positioning blocks, which can arrange the metal tube laterally along the conveyor belt. Two symmetrically arranged grinding components are provided on both sides of the conveyor. Each grinding component includes a grinding head that points towards the conveyor belt and can rotate. The power mechanism can drive the grinding heads of the two grinding components to simultaneously insert into or move away from the metal tube along the axial direction of the metal tube.

[0008] The present invention provides a workpiece deburring device with the following advantages: Driven by a power mechanism, the grinding heads in the two grinding components move inward simultaneously along the axial direction of the metal tube and are inserted into the interior of both ends of the metal tube. Since the grinding heads have a rotating function, they begin to rotate during insertion, ensuring that the surface structure with grinding action fully contacts the inner wall and end burrs of the metal tube, thereby effectively removing the burrs. This device enables continuous grinding and deburring of metal tubes, improving work efficiency. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figures 1-4 A deburring device for removing burrs from both ends of a metal tube includes a conveyor 1 capable of intermittent movement and a power mechanism 13. The conveyor belt of the conveyor 1 is provided with spaced positioning blocks 2, for example, the positioning blocks have V-shaped grooves. The metal tube is placed in the V-shaped grooves. The positioning blocks 2 can arrange the metal tube laterally along the conveyor belt. Two symmetrically arranged grinding components 3 are provided on both sides of the conveyor 1. The grinding components 3 include grinding heads 8 that point towards the conveyor belt and can rotate. The power mechanism 13 can drive the grinding heads 8 of the two grinding components 3 to simultaneously insert into the metal tube or simultaneously move away from the metal tube along the axial direction of the metal tube.

[0016] When deburring is required at both ends of the metal pipe, the conveyor 1 operates intermittently, and the positioning blocks 2 on the conveyor belt are distributed at set intervals. Whenever the conveyor belt stops, a metal pipe is placed on the positioning block 2. The metal pipe can be placed on the positioning block manually or by a robot. The metal pipe is arranged laterally on the conveyor belt and kept in a stable position.

[0017] Driven by the power mechanism 13, the grinding heads 8 in the two grinding components 3 move inward simultaneously along the axial direction of the metal tube and are inserted into the interior of both ends of the metal tube. Since the grinding head 8 has a rotating function, it begins to rotate during insertion, so that the structure with grinding effect on its surface makes full contact with the inner wall and burrs of the metal tube, thereby achieving effective removal of burrs.

[0018] After grinding is completed, the power mechanism 13 reverses its direction, causing the grinding heads 8 in both grinding components 3 to simultaneously retract from the inside of the metal tube. Subsequently, the conveyor 1 restarts, transporting the processed metal tube to the next station and simultaneously sending the next metal tube to be processed to the grinding position to begin a new round of deburring operations.

[0019] This device can achieve the purpose of continuous grinding and deburring of metal pipes, thereby improving work efficiency.

[0020] The power mechanism 13 includes a frame 4 and guide rods 5 fixed to the frame 4 and distributed along the axial direction of the metal tube. The grinding assembly 3 includes a support frame 6, which is slidably connected to the guide rods 5. The grinding head 8 is rotatably connected to the support frame 6. A rotary motor 7 is fixedly connected to the support frame 6, and the rotary motor 7 is drively connected to the grinding head 8.

[0021] The power mechanism 13 includes a frame 4, which serves as the mounting base for the entire device, supporting and fixing various related components. A guide rod 5 is arranged along the axial direction of the metal tube and is fixedly connected to the frame 4, providing guiding support for the reciprocating motion of the grinding assembly 3. The support frame 6 in the grinding assembly 3 is slidably mounted on the guide rod 5, enabling smooth movement along the axial direction of the guide rod 5.

[0022] The grinding head 8 is rotatably mounted on the support frame 6 and can rotate around its central axis. A rotary motor 7 is fixed on the support frame 6. The rotary motor 7 is connected to the grinding head 8 through a transmission structure and is used to drive the grinding head 8 to rotate continuously during the insertion of the metal tube, so that the burrs are removed by rotation when the grinding head 8 contacts the inner wall or end of the metal tube.

[0023] The grinding head 8 includes an outer conical cylinder 11 and an inner conical column 10 coaxially arranged with the metal tube. The inner conical column 10 is located inside the outer conical cylinder 11. Both the inner wall of the outer conical cylinder 11 and the outer wall of the inner conical column 10 are provided with steel wire bristles 12. Moving the grinding head 8 allows the metal tube to be inserted into the annular gap between the outer conical cylinder 11 and the inner conical column 10.

[0024] The grinding head 8 consists of an outer conical cylinder 11 and an inner conical column 10, which are coaxially arranged. The inner conical column 10 is located inside the outer conical cylinder 11, and an annular gap is formed between them. Steel wire bristles 12 are evenly provided on the inner wall of the outer conical cylinder 11 and the outer wall of the inner conical column 10 to make full contact with the inner wall and port burrs of the metal pipe.

[0025] When the grinding head 8 is inserted into one end of the metal tube under the drive of the power mechanism 13, the end of the metal tube is precisely inserted into the annular gap between the outer cone cylinder 11 and the inner cone cylinder 10. At this time, as the rotary motor 7 drives the grinding head 8 to rotate, the wire bristles 12 simultaneously brush and grind the inner and outer walls of the metal tube end, effectively removing the internal and external burrs remaining at the cut of the metal tube.

[0026] The two grinding heads 8 rotate in opposite directions. When the two grinding heads 8 rub against the metal tube, the friction at both ends of the metal tube can be better canceled out, reducing the tendency of the metal tube to rotate in one direction along with the grinding heads 8.

[0027] The power mechanism 13 includes a power telescopic cylinder 14 located between the two grinding components 3. The cylinder barrel of the power telescopic cylinder 14 is fixed to the frame 4. The piston rod of the power telescopic cylinder 14 is equipped with a mounting seat 15. The mounting seat 15 is rotatably connected to a connecting rod 17 through two first hinges 16. The other end of the connecting rod 17 is rotatably connected to the corresponding support frame 6 through a second hinge 18.

[0028] The power mechanism 13 is located between the two grinding components 3, and its core driving element is the power telescopic cylinder 14. The cylinder barrel of the power telescopic cylinder 14 is fixedly mounted on the frame 4, providing stable support. The piston rod of the power telescopic cylinder 14 is connected to a mounting base 15 at its end, serving as a force transmission node.

[0029] The mounting base 15 has two connecting rods 17 rotatably connected to its two sides via first hinges 16, and the other ends of the two connecting rods 17 are rotatably connected to their respective support frames 6 via second hinges 18. The above mechanism forms a symmetrical and linked translational mechanism, which can simultaneously transmit the linear reciprocating motion of the power telescopic cylinder 14 to the two support frames 6.

[0030] When the power telescopic cylinder 14 extends, it pushes the support frame 6 to move outward under the action of the connecting rod 17, so that the grinding head 8 moves away from the metal tube; otherwise, the grinding head 8 moves in the opposite direction.

[0031] It should be noted that, in order to achieve automated and reliable operation of this device in actual industrial scenarios, manual control mode or automatic control mode can be selected according to actual needs.

[0032] In manual control mode, the power telescopic cylinder 14 extends and retracts once each time the conveyor 1 stops.

[0033] In automatic control mode, PLC centralized control is used. The PLC controls the conveyor 1 to transport metal pipes intermittently. A photoelectric sensor installed in front of the grinding head 8 detects that the metal pipe has arrived: the sensor signal is input to the PLC, and the PLC outputs a signal to stop the conveyor 1; the PLC sends a control signal to switch the solenoid valve and drive the power telescopic cylinder 14 to retract; the rotary motor 7 continues to rotate and does not stop with the telescopic movement; the PLC delays the grinding time (e.g., 3 to 5 seconds), and then outputs an extension command, and the grinding head 8 exits; the PLC restarts the conveyor 1 and enters the next cycle.

[0034] refer to Figure 2Symmetrically distributed inclined guide plates 9 are provided on both sides of the conveyor 1 and upstream of the grinding assembly 3. If the metal is placed manually, it is troublesome to align the two ends. As the conveyor belt moves, the inclined guide plates 9 will center the metal tube.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any technical solution, concept, or design obtained by those skilled in the art by making equivalent substitutions or changes based on the technical solution and utility model concept disclosed in the present utility model should be included within the protection scope of the present utility model.
