[0027] Reference Figures 1 to 4 A pipe polishing device according to a preferred embodiment of the present application will be described in detail below, which is used for polishing the end side wall and cross section of a pipe 90. The pipe polishing device comprises a device main body 10, a polishing assembly 20, a driving assembly 30 and a clamping assembly 40, wherein the driving assembly 30 and the clamping assembly 40 are installed on the device main body 10.
[0028] The polishing assembly 20 comprises a polishing main body 21 and a polishing sheet 22, wherein the polishing main body 21 is installed on the device main body 10, and the polishing main body 21 is connected to the driving assembly 30 in a rotatable and drivable manner. The polishing main body 21 is formed with a polishing groove 2101 with a rotational axis, the inner diameter and the slot size of the polishing groove 2101 are equal to the cross section diameter of the pipe 90, and the pipe 90 can be inserted into the polishing groove 2101 and the inner wall of the polishing main body 21 can be fitted with the end outer wall of the pipe 90 inserted into the polishing groove 2101.
[0029] The polishing sheet 22 is installed on the inner wall of the polishing groove 2101 formed by the polishing main body 21, and the surface of the polishing sheet 22 faces the slot of the polishing groove 2101, the polishing sheet 22 is opposite to the end cross section of the pipe 90 inserted into the polishing groove 2101, and the polishing sheet 22 is fitted with the end cross section of the pipe 90 when the pipe 90 is inserted into the polishing groove 2101.
[0030] As an example, the driving assembly 30 is implemented to comprise a driving motor.
[0031] Preferably, the polishing sheet 22 is installed on the inner wall of the polishing groove 2101 formed by the polishing main body 21 with the rotational axis of the polishing main body 21 as the center, and the polishing sheet 22 has at least a ring-shaped part equal to the end cross section area of the pipe 90. That is, the polishing sheet 22 is at least a ring-shaped sheet that can be fitted with the end cross section of the pipe 90.
[0032] After the end of the pipe 90 is inserted into the polishing groove 2101, the pipe 90 is clamped and fixed by the clamping assembly 40 to avoid the pipe 90 from being rotated by the polishing main body 21.
[0033] The skilled person can understand that when the end of the pipe 90 is inserted into the grinding groove 2101, the pipe 90 is clamped and fixed by the clamping assembly 40. At this time, the outer wall of the end of the pipe 90 inserted into the grinding groove 2101 is in contact with the inner wall of the grinding groove 2101 formed by the grinding body 21, and the end cross section of the pipe 90 is in contact with the grinding sheet 22. When the grinding body 21 is driven to rotate by the driving assembly 30, the grinding body 21 rotates to drive the grinding sheet 22 to rotate, so that the outer wall of the end of the pipe 90 inserted into the grinding groove 2101 and the end cross section are ground by the grinding body 21 and the grinding sheet 22, thereby simultaneously grinding the outer wall of the end of the pipe 90 inserted into the grinding groove 2101 and the end cross section.
[0034] Preferably, the inner diameter and the size of the slot of the grinding groove 2101 of the grinding body 21 are greater than the cross-sectional diameter of the pipe 90, and the pipe 90 is inserted into the grinding groove 2101 in a manner that the central axis coincides with the rotation axis of the grinding body 21. The grinding assembly 20 further comprises at least one grinding piece 23, which is rotatably installed in the grinding groove 2101 in a manner that the rotation axis is parallel to the rotation axis of the grinding body 21, and the grinding piece 23 is at a predetermined distance from the center of the grinding groove 2101, so that at least part of the side wall of the grinding piece 23 is in contact with the outer wall of the end of the pipe 90 inserted into the grinding groove 2101. When the end of the pipe 90 is inserted into the grinding groove 2101, the grinding piece 23 itself can rotate and rub against the outer wall of the end of the pipe 90 inserted into the grinding groove 2101, so that when the grinding piece 23 encounters too much resistance during grinding, it can rotate to bypass part of the outer wall of the end of the pipe 90 inserted into the grinding groove 2101, so that the grinding piece 23 does not rub against the pipe 90 by force when encountering too much resistance, thereby avoiding damage to the pipe 90.
[0035] Preferably, the same number of rotating columns 211 as the grinding pieces 23 are formed in the grinding groove 2101 of the grinding body 21, and the rotating columns 211 are parallel to the rotation axis of the grinding body 21 and can rotate. Each grinding piece 23 is installed in the grinding groove 2101 by one rotating column 211, and the side wall of each grinding piece 23 is in contact with the outer wall of the end of the pipe 90 inserted into the grinding groove 2101. In this way, the grinding piece 23 can rotate around the rotating column 211 to grind the outer wall of the end of the pipe 90 inserted into the grinding groove 2101.
[0036] Specifically, the rotating column 211 is arranged to be rotatable through a bearing. The polishing member 23 is formed with a fixed portion 231 at one end of the slot of the polishing groove 2101 and centered on the rotating column 211. The fixed portion 231 is internally threaded, and the rotating column 211 is threaded near the end surface of the slot of the polishing groove 2101. The fixed portion 231 is screwed to the end of the rotating column 211 to fix the polishing member 23 to the rotating column 211. When the polishing member 23 rubs against the pipe 90, the polishing member 23 rotates about the rotating column 211.
[0037] Preferably, the side wall surface of the polishing member 23 is formed with a polishing pattern 221 that spirally surrounds the side wall surface of the polishing member 23 to avoid engaging with the external wall pattern of the pipe 90, thereby enhancing the polishing effect.
[0038] Preferably, the polishing member 23 is implemented as a cylinder, and the number of the polishing members 23 is implemented as eight. The eight polishing members 23 are symmetrically distributed in the polishing groove 2101 about the rotation center of the polishing body 21, and the distance between adjacent polishing members 23 is the same. When the pipe 90 is inserted into the polishing groove 2101, the cylindrical side wall of the polishing member 23 fits the external wall of the portion of the pipe 90 inserted into the polishing groove 2101, and the eight polishing members 23 fit the external wall of the pipe 90 from eight directions, thereby increasing the contact area between the pipe 90 and the polishing members 23, enhancing the polishing effect and making the polishing more delicate.
[0039] Preferably, the clamping assembly 40 includes at least one clamping drive member 41 and at least one clamping member 42, wherein the clamping member 42 is drivingly connected to the clamping drive member 41. The clamping drive member 41 is mounted to the device body 10 and can drive the clamping member 42 to clamp the pipe 90, so that the portion of the pipe 90 outside the polishing groove 2101 is clamped by the clamping assembly 40, so that the pipe 90 as a whole cannot move, avoiding the pipe 90 from rotating simultaneously when the polishing body 21 rotates, thereby making the polishing effect poor.
[0040] In one embodiment, the number of the clamping drive member 41 and the clamping member 42 is implemented as one. The clamping member 42 is arranged on the other side of the pipe 90 relative to the device body. When the clamping drive member 41 drives the clamping member 42 to approach and press against the pipe 90, the pipe 90 is clamped and fixed by the clamping member 42 and the device body 10.
[0041] In another embodiment, the number of the clamping driving members 41 is one, and the number of the clamping members 42 is two. The two clamping members 42 are oppositely arranged on two sides of the pipe 90, and one of the clamping members 42 is fixed to the device body 10, and the other clamping member 42 is connected to the clamping driving member 41 and can be driven to press against or move away from the pipe 90. When the clamping driving member 41 drives the clamping member 42 to press against the pipe 90, the pipe 90 is pressed by the moving clamping member 42 to the fixed clamping member 42 to be clamped and fixed, thereby facilitating polishing.
[0042] In a preferred embodiment, the number of the clamping driving members 41 and the clamping members 42 is two. The two clamping members 42 are oppositely arranged on two sides of the pipe 90, and the two clamping members 42 are connected to the clamping driving members 41 and can be driven to press against or move away from the pipe 90. When the two clamping driving members 41 respectively drive the two clamping members 42 to press against the pipe 90, the pipe 90 is clamped and fixed by the two clamping members 42.
[0043] As an example, the clamping driving member 41 is implemented to include a pneumatic cylinder.
[0044] Preferably, the clamping member 42 is arranged to be arc-shaped near the end face of the pipe 90, and the arc face of the clamping member 42 is adapted to the arc face of the pipe 90, so that the contact area between the clamping member 42 and the pipe 90 is increased, thereby increasing the friction between the clamping member 42 and the pipe 90 when the clamping member 42 presses against the pipe 90, and thereby making the pipe 90 not easy to move.
[0045] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and the drawings are only examples and do not limit the utility model. The advantages of the utility model have been fully and effectively realized. The functions and structural principles of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be any deformation or modification without departing from the principles.
