Description

Technical Field

[0001] The present invention relates to the field of finishing equipment for special-shaped pipes, and particularly to a grinding and polishing device for special-shaped pipe materials. Background Art

[0002] Pipes are divided into inner and outer parts. For the outer wall of the pipe, in combination with the actual processing process, its processing difficulty is significantly lower than that of the inner wall of the pipe. The reason is that there is enough space outside the pipe to facilitate the equipment to carry out processing projects, but the narrow space inside the pipe makes it difficult or even impossible for the corresponding equipment to extend into the pipe. Therefore, filling the pipe with enough grinding medium, making the grinding medium fully contact the inner wall of the pipe, and using the relative movement between the two to make the contact surface of the inner wall of the pipe be rubbed is one of the excellent ways to process the inner wall of special-shaped pipes.

[0003] Burying the pipe in the polishing pool, making the grinding medium fully enter the pipe, and using a fixture to hold the pipe and make the pipe move along the length direction of the pipe are the general processing steps for polishing the inner wall of the pipe.

[0004] Pipes have different lengths, that is, when the pipe length is less than the length of the polishing pool, the pipe can be polished. On the contrary, when the pipe length is greater than the length of the polishing pool, the pipe cannot correspond to the polishing pool. Therefore, the length of the polishing pool is the main reason restricting the polishing of pipes of different lengths. In combination with the actual situation, building a polishing pool with a large length has a high investment cost. Accordingly, a new polishing method for the inner wall of the pipe is established to meet the polishing requirements of most pipes without increasing the processing cost. Summary of the Invention

[0022] The beneficial effects of the present invention are:

[0023] 1. The present invention provides a device for grinding and polishing special-shaped tubes using a flipping method. The device uses a porous tube as a central component and is designed to insert the special-shaped tube into the porous tube and apply pressure with a bridging plate. In combination with the rotation of the support member, a suction pump is used to absorb abrasive media such as abrasive particles. Accordingly, the abrasive media is ejected outward from the small holes in the porous tube to the inner wall of the special-shaped tube, and based on the fallen abrasive media, the relative gap between the porous tube and the special-shaped tube is continuously filled to perform a pre-polishing treatment on the special-shaped tube.

[0024] 2. In the present invention, the characteristics of the arrangement of the straps to the support members enable the straps originally used to press the special-shaped tube to deflect in a predetermined rotational direction before the porous tube. Accordingly, in combination with the adapter, the slider covering the first and second openings is moved away from the first and second openings, that is, the first and second openings are exposed outwardly. In the subsequent flipping, combined with the factor of gravity, the grinding medium slides into the relative gap between the porous tube and the special-shaped tube, thereby continuously rubbing the inner wall of the special-shaped tube.

[0025] 3. In the present invention, the length of the porous tube is greater than that of the special-shaped tube, and the device can grind and polish the special-shaped tube. From the perspective of difficulty in setting up, the difficulty of changing the length of the porous tube is much lower than the difficulty of setting up a polishing pool.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only preferred embodiments of the present invention and are not exhaustive. Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without making any creative work are all within the scope of protection of the present invention.

[0040] Specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0041] Example 1

[0042] In this embodiment, a device for grinding and polishing special-shaped pipes is proposed, including a material pool 10. The material pool 10 has an outwardly exposed accommodating chamber, and the accommodating chamber is filled with abrasive media such as abrasive particles for pipe polishing. It should be noted that in this embodiment, the abrasive media should not exceed the top edge of the material pool 10 after being filled.

[0043] See alsoFigure 1-4 , a support frame 8 is erected from the accommodating chamber toward any side wall of the material pool 10, and the support frame 8 is parallel to the material pool 10 in the height direction thereof. Accordingly, the support frame 8 is used as the supporting body, the motor base 11 is connected to the support frame 8, and the support frame 8 is extended to the top of the accommodating chamber. It should be noted that the motor base 11 is the mounting structure of the motor 6, which carries the motor 6 on its back, so that the extension direction of the output shaft of the motor 6 is perpendicular to the support frame 8 at ninety degrees.

[0044] A support member 4 is installed at the end of the output shaft of the motor 6. It should be noted that a suction pump 7 with a material-taking range extending to the material pool 10 is provided on the flip surface of one side of the support member 4. In addition, a porous tube 3 is installed on the flip surface of the other side of the support member 4. The porous tube 3 is a quilt kit of the special-shaped tube, and a first opening connected to the porous tube 3 is provided at the junction of the porous tube 3 and the support member 4, and a plurality of second openings surrounding the first opening are arranged in a circular array at the first opening; the support member 4 is also an installation structure of the strap 9, that is, the strap 9 is inserted through the support member 4 and is rotatably connected to the support member 4, so that one end of the strap 9 inserted through the support member 4 is laid on the surface of the special-shaped tube.

[0045] See also Figure 9 The opening and closing member 5 includes a slider 51 and a transition portion 52, wherein the slider 51 is connected to the suction pump 7 and slides at the locations where the first and second openings are set up. The two ends of the transition portion 52 are respectively rotatably connected to the slider 51 and the strap 9, and are used to intercept the torque when the strap 9 is deflected relative to the porous tube 3. The slider 51 slides back and forth to the locations where the first and second openings are set up, so that the first and second openings are exposed or closed outward.

[0046] In conjunction with the above instructions, please refer to Figure 6 and Figure 7The present embodiment provides a device for grinding and polishing a special-shaped tube by a flipping method. The device uses a porous tube 3 as a central component, and is intended to insert the special-shaped tube into the porous tube 3 and press it with a strap 9. In combination with the rotation of the support member 4, a suction pump 7 is used to absorb abrasive media such as abrasive particles. Accordingly, the abrasive media is ejected outward from the small holes in the porous tube 3 to the inner wall of the special-shaped tube, and based on the falling abrasive media, the relative gap between the porous tube 3 and the special-shaped tube is continuously filled to perform a pre-polishing treatment on the special-shaped tube. Subsequently, in combination with the establishment characteristics of the strap 9 to the support member 4 (by The support member 4 is a dividing line, so that the portion of the strap 9 inserted through the support member 4 is longer than the other portion not inserted through the support member 4), so that the strap 9 originally used to press the special-shaped tube is deflected in a predetermined rotation direction before the porous tube 3, thereby combining with the adapter 52 to make the slider 51 covering the first opening and the second opening move away from the first opening and the second opening, that is, the first opening and the second opening are exposed to the outside, and in the subsequent flipping, combined with the gravity factor, the grinding medium slides into the relative gap between the porous tube 3 and the special-shaped tube, thereby continuously rubbing the inner wall of the special-shaped tube, and falling back into the material pool 10 from the second opening.

[0047] It should be noted that after the slider 51 releases its cover from the first opening, its port for conveying the grinding medium is in close contact with the surface of the support member 4, causing the internal pressure of the suction pump 7 to increase. Based on this, a pipe pressure sensor is installed at the suction pump 7 to cooperate with the sliding movement of the slider 51 and intelligently identify the relative position of the slider 51 to the support member 4.

[0048] See also Figure 2 and Figure 4 The direction indicated by the middle arrow is the object pointed by the arrow, which is the special-shaped tube. Therefore, as long as the length of the porous tube 3 is greater than the special-shaped tube, the device described in this embodiment can grind and polish the special-shaped tube. From the perspective of difficulty in establishment, the difficulty of changing the length of the porous tube 3 is much lower than the difficulty of establishing a polishing pool. In addition, the device described in this embodiment has significantly lower requirements for the amount of grinding media than the requirements for grinding media required to establish a large-scale polishing pool. The reason is that during the rotation of the support member 4, the suction pump 7 can absorb the grinding media as long as it can reach the grinding media in the material pool 10.

[0049] The specific configurations of the support member 4 and the suction pump 7 are described below:

[0050] For support member 4, please refer to Figure 10 ;

[0051] The support member 4 includes a support plate 41, which is a mounting member for the suction pump 7, the slider 51 and the porous tube 3. The support plate 41 is connected to the output shaft of the motor 6 so that the support plate 41 rotates alternately in the clockwise and counterclockwise directions.

[0052] Furthermore, a strap through groove 43 is provided at the support plate 41 for the strap 9 to be inserted and rotatably connected to the support plate 41; a slider groove 45 for the slider 51 to slide is provided at the support plate 41 facing away from the porous tube 3, wherein the first opening and the second opening are within the arrangement range of the slider groove 45, and are used to expose or cover the first opening and the second opening when the slider 51 slides into the slider groove 45. It should be noted that in this embodiment, the first opening is the injection hole 44, and the second opening is the discharge hole 42.

[0053] For suction pump 7, see Figure 9 It includes a pump body 72 and a material delivery pipe 73 and a suction pipe 71 respectively arranged at two positions of the pump body 72. The suction pipe 71 extends into the material pool 10 and absorbs the grinding medium when the support plate 41 rotates. The pump body 72 is connected to the slider 51, so that the material in the pump body 72 enters the porous tube 3 along the passage formed by the slider 51 and the injection hole 44.

[0054] The following describes the sliding process of the slider 51 to the supporting member 4 in combination with the specific configurations of the supporting member 4 and the suction pump 7:

[0055] ①Please refer to Figure 2 and Figure 6 Because the portion of the butt plate 9 that is inserted through the support member 4 is longer than the portion that is not inserted through the support member 4, the butt plate 9 is tilted and placed on the surface of the special-shaped tube under the action of gravity. Therefore, the motor 6 is used to apply torque to the support plate 41, so that the support plate 41 is Figure 6 Rotate clockwise to Figure 7 In the illustrated configuration, during rotation, the strap 9 is affected by two forces: gravity and the resistance it encounters when contacting the abrasive medium during rotation. Consequently, the strap 9 spends most of its time in contact with the surface of the profiled tube during the clockwise rotation cycle of the support plate 41. Therefore, the suction pump 7 has sufficient time to transport the abrasive medium into the gap between the porous tube 3 and the profiled tube.

[0056] ②Please refer to Figure 4 and Figure 7 Because the portion of the strap 9 that is inserted through the support member 4 is longer than the other portion that is not inserted through the support member 4, the strap 9 that originally pressed the special-shaped tube is deflected in the predetermined rotation direction before the porous tube 3 without the influence of resistance. During the deflection, combined with the adapter 52, the slider 51 covering the injection hole 44 and the second opening is moved away from the injection hole 44 and the discharge hole 42, that is, the injection hole 44 and the discharge hole 42 are exposed to the outside, and in the subsequent flipping, combined with the gravity factor, the grinding medium slides into the relative gap between the porous tube 3 and the special-shaped tube, and then continues to rub the inner wall of the special-shaped tube, and falls back into the material pool 10 through the discharge hole 42.

[0057] Example 2

[0058] In this embodiment, a device for grinding and polishing special-shaped pipes is proposed, including a material pool 10. The material pool 10 has an outwardly exposed accommodating chamber, and the accommodating chamber is filled with abrasive media such as abrasive particles for pipe polishing. It should be noted that in this embodiment, the abrasive media should not exceed the top edge of the material pool 10 after being filled.

[0059] See also Figure 1-4 , a support frame 8 is erected from the accommodating chamber toward any side wall of the material pool 10, and the support frame 8 is parallel to the material pool 10 in the height direction thereof. Accordingly, the support frame 8 is used as the supporting body, the motor base 11 is connected to the support frame 8, and the support frame 8 is extended to the top of the accommodating chamber. It should be noted that the motor base 11 is the mounting structure of the motor 6, which carries the motor 6 on its back, so that the extension direction of the output shaft of the motor 6 is perpendicular to the support frame 8 at ninety degrees.

[0060] A support member 4 is installed at the end of the output shaft of the motor 6. It should be noted that a suction pump 7 with a material-taking range extending to the material pool 10 is provided on the flip surface of one side of the support member 4. In addition, a porous tube 3 is installed on the flip surface of the other side of the support member 4. The porous tube 3 is a quilt kit of the special-shaped tube, and a first opening connected to the porous tube 3 is provided at the junction of the porous tube 3 and the support member 4, and a plurality of second openings surrounding the first opening are arranged in a circular array at the first opening; the support member 4 is also an installation structure of the strap 9, that is, the strap 9 is inserted through the support member 4 and is rotatably connected to the support member 4, so that one end of the strap 9 inserted through the support member 4 is laid on the surface of the special-shaped tube.

[0061] See also Figure 9 The opening and closing member 5 includes a slider 51 and a transition portion 52, wherein the slider 51 is connected to the suction pump 7 and slides at the locations where the first and second openings are set up. The two ends of the transition portion 52 are respectively rotatably connected to the slider 51 and the strap 9, and are used to intercept the torque when the strap 9 is deflected relative to the porous tube 3. The slider 51 slides back and forth to the locations where the first and second openings are set up, so that the first and second openings are exposed or closed outward.

[0062] The difference from Example 1 is that a sleeve 2 movably sleeved on the porous tube 3 is installed at the other end of the junction of the porous tube 3 and the supporting member 4. The sleeve 2 is wrapped around the porous tube 3 and always presses against one end of the special-shaped tube.

[0063] For Example 1, it is necessary for the special-shaped tube to completely cover the 3 small holes of the porous tube. However, when the special-shaped tube cannot completely cover the 3 small holes of the porous tube, the grinding medium sucked by the suction pump 7 will overflow outward along the uncovered small holes. Accordingly, in this embodiment, a sleeve 2 is used to be sleeved on the part of the special-shaped tube and the porous tube 3 relative to the exposed part of the special-shaped tube. On the one hand, combined with the strap 9, the special-shaped tube is further limited and fixed. On the other hand, the originally uncovered small holes are covered and wrapped to prevent the grinding medium from being discharged outward from the small holes.

[0064] The modification of this embodiment is limited to setting a sleeve 2 at the porous pipe 3. For how to use the device described in this embodiment, please refer to Embodiment 1.

[0065] Embodiment 3

[0066] Embodiment 3 is an extended embodiment of Embodiment 1 and Embodiment 2. That is, considering that the bridging plate 9 will extend into the material pool 10 and contact the grinding medium when the supporting member 4 flips, accordingly, a vibration generating table 1 located in the rotation path of the supporting member 4 is provided in the material pool 10.

[0067] For the vibration generating table 1, please refer to Figure 1-4 , Figure 12 , which includes a table main body 101. The top of the table main body 101 has a concave curved surface, and a plurality of elastic pieces 102 are arranged in an array on this curved surface. The elastic pieces 102 extend into the rotation range of the bridging frame 9, so that the elastic pieces 102 can alternately contact the bridging plate 9 during the rotation of the bridging plate 9.

[0068] The elastic pieces 102 are to hinder the rotation of the bridging plate 9. It should be noted that this hindrance does not limit the rotation of the bridging plate 9. When the bridging plate 9 pushes the elastic pieces 102, the elastic pieces 102 deform, thereby generating vibrations transmitted to the special-shaped pipe, so as to combine the impact of the grinding medium on the inner wall of the special-shaped pipe to obtain a better grinding and polishing effect.

[0069] It should be noted that the support frame 8 used in Embodiment 1, Embodiment 2, and Embodiment 3 includes a pull rod 81, two insertion rods 82, and a support frame main body 83 combined with the material pool 10. One of the insertion rods 82 penetrates the combined body of the motor pedestal 11 and the support frame main body 83, so that the motor pedestal 11 is fixed to the support frame main body 83. The other insertion rod 82 is located above the motor pedestal 11. It penetrates the support frame main body 83 and exposes both ends outward relative to the support frame main body 83, so that one end of the pull rod 81 is fixed to the exposed end and obliquely pulls the other end where the motor pedestal 11 is combined with the support frame main body 83.

[0070] Please refer to Figure 5 , the motor pedestal 11 extends upward from the support frame main body 83 to above the accommodating chamber. In addition, the motor pedestal 11 is also a load-bearing member for components such as the motor 6 and the supporting member 4. Accordingly, the pull rod 81 is used to obliquely pull the motor pedestal 11, thereby evenly distributing the weight borne by the support frame main body 83.

[0071] Furthermore, the pull rod 81 can be one of a rope, a rod, and a pipe.

[0072] In the present invention, unless otherwise clearly defined and limited, the first feature being "on" or "under" the second feature may include direct contact between the first and second features, or may include the first and second features not being in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes the first feature being directly above and obliquely above the second feature, or merely indicating that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes the first feature being directly under and obliquely under the second feature, or merely indicating that the horizontal height of the first feature is less than that of the second feature.

[0073] The foregoing has shown and described the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
