Description

Technical Field

[0001] This utility model belongs to the field of plastic deburring, specifically, it relates to an automated control plastic deburring device with replaceable grinding heads. Background Technology

[0002] Plastic pipes are generally made from synthetic resin, namely polyester, as the main raw material, with the addition of stabilizers, lubricants, and plasticizers. They are processed by extrusion in a pipe-making machine using a "plastic" method. The processed plastic pipes are then cut into fixed-length plastic pipe sections by a pipe-cutting machine. Because the cutting surface of the plastic pipe by the pipe-cutting machine is relatively rough, there are many burrs on the end face of the fixed-length plastic pipe sections, which will affect the use of the plastic pipe sections.

[0003] Chinese Patent No. CN222627205U discloses a deburring device for plastic pipe production, comprising: a workbench, with symmetrically mounted support columns at the bottom of the workbench, a bracket mounted on the top of the workbench, a grinding disc rotatably mounted inside the bracket, a motor connected to the driving end of the grinding disc via an electric telescopic rod, a rotating platform rotatably mounted inside the workbench, clamping plates rotatably mounted longitudinally on the top of the rotating platform, an auxiliary mechanism at the connection between the rotating platform and the workbench, and a rotating mechanism below the rotating platform.

[0004] The deburring device for plastic pipe production disclosed in this application, although it clamps and fixes the plastic pipe by moving two clamping plates in opposite directions, has a fixed curvature and is difficult to change according to the diameter of the plastic pipe. This makes it difficult to flexibly adjust the device according to the diameter of different specifications of plastic pipes, which easily affects the clamping stability of the device on the plastic pipe.

Detailed Implementation

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Please see Figure 1-6 As shown, this embodiment provides an automated plastic deburring device with a replaceable grinding head, including: a support frame, a rotating component and a lifting component are arranged on the upper part of the support frame, a grinding component is arranged on the upper part of the lifting component, and the grinding component is located above the rotating component;

[0032] A vertical plate 23 is mounted on the upper surface of the rotating assembly. A fixing block 24 is mounted on one side of the upper part of the vertical plate 23. Fixing boxes 26 are mounted on both the upper and lower sides of the fixing block 24. An electric push rod 25 is mounted on one side of the fixing box 26. The two electric push rods 25 are respectively mounted on the upper and lower sides of the fixing block 24. The electric push rods 25 are located between the fixing box 26 and the vertical plate 23. A trapezoidal block 27 is fixedly connected to the output end of the electric push rod 25. The trapezoidal block 27 is slidably fitted inside the fixing box 26. A sliding block 28 is mounted on one side of the trapezoidal block 27. The trapezoidal block 27 is located between the sliding block 28 and the electric push rod 25. The end of the moving block 28 away from the trapezoidal block 27 is rotatably fitted with a first rubber wheel 29. There are two L-shaped clamping arms 30 that rotatably rotate within the fixed box 26. The trapezoidal block 27 and the sliding block 28 are both located between the two L-shaped clamping arms 30. The two ends of the L-shaped clamping arms 30 are respectively provided with a second rubber wheel 32 and a roller 33 that rotatably engages with them. The roller 33 is in contact with the inclined surface of the trapezoidal block 27. The first rubber wheel 29 and the second rubber wheel 32 are both located on the side of the fixed box 26 away from the electric push rod 25. The rubber hardness of the first rubber wheel 29 and the second rubber wheel 32 is Shore A60±5 and the coefficient of friction is μ≥0.4.

[0033] The sliding block 28 has a first movable groove at its end, and a first rod is installed between the upper and lower sides of the first movable groove. The first rubber wheel 29 is sleeved on the periphery of the first rod. The L-shaped clamping arm 30 has a second movable groove at both ends, and a second rod is installed between the upper and lower sides of the second movable groove. The second rubber wheel 32 is installed on the periphery of the corresponding second rod, and the roller 33 is sleeved on the periphery of the corresponding second rod.

[0034] One application of this embodiment is as follows: In use, the plastic tube workpiece is first placed on the rotating assembly. Then, the electric push rod 25 is activated. The output end of the electric push rod 25 extends and pushes the trapezoidal block 27 to slide into the fixed box 26. The sliding of the trapezoidal block 27 forces the two rollers 33 to move away from each other, thereby driving the L-shaped clamping arm 30 to rotate, causing the two second rubber wheels 32 to move closer together. At the same time, the movement of the trapezoidal block 27 also pushes the sliding block 28 and the first rubber wheel 29 to slide synchronously, so that the first rubber wheel 29 and the two second rubber wheels 32 come together and clamp the workpiece. Then, the rotating assembly drives the vertical plate 23 and the fixed block 24 to rotate the workpiece. At the same time, the lifting assembly adjusts the position of the grinding assembly according to the length of the workpiece, so that the grinding assembly deburrs the workpiece. Similarly, after the processing is completed, referring to the above operation, the first rubber wheel 29 and the second rubber wheel 32 can be controlled to release the workpiece to achieve replacement or removal. It should be noted that all electrical equipment involved in this application can be powered by a battery or an external power source.

[0035] The vertical plate 23 and the fixed block 24 work together to support the two fixed boxes 26. The electric push rod 25 pushes the trapezoidal block 27, the sliding block 28 and the first rubber wheel 29 to slide. The inclined surface of the trapezoidal block 27 squeezes the roller 33 to make the L-shaped clamping arm 30 and the second rubber wheel 32 rotate. This makes it easier for the first rubber wheel 29 and the two second rubber wheels 32 to clamp the workpiece together, realize the control of three-point synchronous clamping, improve the adaptability, stability and disassembly convenience of the device for clamping plastic tube workpieces. At the same time, the height of the grinding component can be adjusted with the lifting component, which makes it easy for the device to automatically deburr plastic tube workpieces of various diameters and lengths.

The L-shaped clamping arm 30 is located between the spring 31 and the sliding block 28. The shaft 34 improves the stability of the rotation of the L-shaped clamping arm 30, and the spring 31 facilitates the automatic reset of the L-shaped clamping arm 30 when the electric push rod 25 retracts.
