[0002] Pipe bends are one of the most common connecting pipe fittings, and pipe polishing is one of the important process steps in pipe bend processing.

[0003] Chinese Patent No. CN201220427101.3 discloses a "bent pipe polishing machine". The machine places the bent pipe to be polished between two polishing mechanisms. Then, by driving the turntable to rotate, the outer circumference of the bent pipe is completely polished between two circumferentially rotating polishing belts. Furthermore, by driving the bent pipe to move along the central arc direction, the outer circumferential surface passes between the two polishing mechanisms in sequence to complete the polishing of the entire pipe.

[0004] However, the problem with the aforementioned polishing machine is that the method of controlling the movement of the bent tube is not disclosed. The most common method is manual operation. Since manual operation is prone to movement errors, it leads to uneven polishing of the outer surface of the bent tube, which reduces the quality of the finished product. Summary of the Invention

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1-5As shown, this invention discloses a high-efficiency pipe polishing machine, comprising a frame 1, a rotating disk 2, a first drive mechanism 91, and a polishing assembly 3. The rotating disk 2 is disc-shaped, with its axis along the front-rear direction. The rotating disk 2 is rotatably mounted on the frame 1. The first drive mechanism 91 drives the rotating disk 2 to rotate. The polishing assembly 3 is disposed on the rotating disk 2, and a polishing position 21 is provided at the rotation center of the rotating disk 2. Furthermore, it includes a pipe control assembly 4, which includes a mounting base plate 41, a rotating frame 42, a second drive mechanism 43, and a mating mold 44. The rotating frame 42 is rotatably mounted on the mounting base plate 41, and its rotation axis is vertically oriented. The second drive mechanism 43 drives the rotating disk 2 to rotate. The rotating frame 42 rotates. In addition, the mating mold 44 includes a connecting section 441 and a mating fan ring 442. The connecting section 441 is fixedly connected to the upper end of the rotating frame 42 by an interference fit. One end of the mating fan ring 442 is integrally formed and connected to the connecting section 441. The outer circumferential shape and size of the mating fan ring 442 are adapted to the inner circumferential shape and size of the bent pipe to be polished. This allows the bent pipe to be processed to be installed by inserting it into the mating fan ring 442 on the side away from the connecting section 441. In addition, the central axis of the mating fan ring 442 is coaxial with the rotation axis of the rotating frame 42, and the polishing position 21 is located on the ring where the mating fan ring 442 is located.

[0033] Therefore, the first drive mechanism 91 drives the rotating disk 2 to rotate, thereby driving the polishing component 3 to work. Then, after the bent tube to be polished is placed on the matching fan ring 442, the second drive mechanism 43 drives the bent tube to pass through the polishing position 21 continuously and stably. When passing through the polishing position 21, the rotating polishing component 3 performs circumferential full-door polishing on the bent tube part located at the polishing position 21. Thus, after the bent tube completely passes through the polishing position 21, the full processing is completed, and the outer peripheral surface is polished evenly, resulting in high finished product quality of the bent tube.

[0034] Specifically, the frame 1 has four rotatably mounted support wheels 11 on the outer periphery of the rotating disk 2, so that the rotating disk 2 can be rotatably mounted on the frame 1 through the cooperation of the four support wheels 11 and the rotating disk 2.

[0035] Specifically, the first drive mechanism 91 includes a first motor 911, a first gear 912, and a second gear 913. The first motor 911 is fixedly mounted on the frame 1, the first gear 912 is fixedly mounted on the output shaft of the first motor 911, and the second gear 913 is fixedly mounted on the rotating disk 2 and coaxial with the rotating disk 2. The first gear 912 and the second gear 913 mesh, so that under the operation of the first motor 911, the first gear 912 and the second gear 913 cooperate to realize the rotation of the rotating disk 2.

[0036] Specifically, the second drive mechanism 43 adopts a second motor (servo motor), which is fixedly installed below the mounting base 41, and the rotating frame 42 is fixedly installed on the output shaft of the second motor, thereby realizing the rotation of the rotating frame 42 under the operation of the second motor.

[0037] In addition, in this embodiment, the mounting base plate 41 is slidably mounted on the frame 1 in the front-back direction. The frame 1 is provided with a third drive mechanism 92 for driving the mounting base plate 41 to slide. If there is a certain deviation between the polishing position 21 and the ring where the matching fan ring 442 is located, the mounting base plate 41 can be driven to slide by the third drive mechanism 92 to drive the matching fan ring to align with the polishing position 21, thereby ensuring the accuracy of the corresponding position and ensuring the smoothness of polishing.

[0038] Specifically, the third drive mechanism 92 includes a third motor 921, a lead screw 922, and a nut seat 923. The lead screw 922 is rotatably mounted on the frame 1 with its axis along the front-back direction. The third motor 921 is fixedly mounted on the frame 1, and the output shaft of the third motor 921 is connected to the lead screw 922. The nut seat 923 is fixedly mounted on the lower end of the mounting base plate 41 and is threadedly connected to the lead screw 922. Thus, the third motor 921 drives the lead screw 922 to rotate, thereby causing the nut seat 923 and the mounting base plate 41 to move in the front-back direction.

[0039] In addition, in this embodiment, the frame 1 is provided with a processing space 12 on the rear side of the rotating disk 2, and the frame 1 is provided with a protective cover 13 covering the rotating disk 2 on the front side of the rotating disk 2. The polishing component 3 is located in the processing space 12. Furthermore, the rotating disk 2 is provided with a first through hole 22 in the front-back direction, and the protective cover 13 is provided with a second through hole 131 in the front-back direction. This allows the bent tubes to be processed on the mating mold 44 to pass through the second through hole 131 and the first through hole 22 in sequence into the processing space 12. During the polishing process in the processing space 12, the debris generated is concentrated in the processing space 12 to prevent debris from splashing.

[0040] Preferably, in this embodiment, the processing space 12 is provided with a negative pressure hole 14 and a control opening 15 through the frame 1. The frame 1 is provided with an opening and closing plate 16 for opening and closing the control opening 15. Therefore, the negative pressure hole 14 can be connected to a negative pressure pipe so that during the processing, the negative pressure hole 14 generates negative pressure to better collect and discharge the splashed debris. In addition, the control opening 15 is opened by the opening and closing plate 16 to allow for maintenance within the processing space 12.

[0041] The opening and closing plate 16 is opened and closed by vertical sliding.

[0042] In this embodiment, the polishing assembly 3 includes a polishing belt 31, a first mounting bracket 32, and a second mounting bracket 33. The first mounting bracket 32 ​​and the second mounting bracket 33 are mounted on the rotating disk 2. A first rotating column 34 and a second rotating column 35 are rotatably mounted on the first mounting bracket 32, and a third rotating column 36 and a fourth rotating column 37 are rotatably mounted on the second mounting bracket 33. The polishing belt 31 is sleeved on the first rotating column 34, the second rotating column 35, the third rotating column 36, and the fourth rotating column 37. The polishing belt 31 includes a first polishing section 311 located between the first rotating column 34 and the third rotating column 36, and a second polishing section 312 located between the second rotating column 35 and the fourth rotating column 37. The first polishing section 311 and the second polishing section 312 are symmetrically arranged on both sides of the polishing position 21 along the rotational radial direction of the rotating disk 2, so that the bent tube is polished as the first polishing belt 31 and the second polishing belt 31 rotate circumferentially with the rotating disk 2. Compared with the structure described in the background art, this design only requires a single polishing belt 31, and the structure is simpler.

[0043] The first rotating column 34, the second rotating column 35, the third rotating column 36, and the fourth rotating column 37 are each composed of several bearings. Each bearing is fixedly installed by bolts passing through its inner circumference and by threaded connection to the first mounting bracket 32 ​​or the second mounting bracket 33.

[0044] Furthermore, in this embodiment, the first mounting bracket 32 ​​and the second mounting bracket 33 are both slidably mounted on the rotating disk 2 along the radial direction of the rotating disk 2 by means of slide rail snap-fit. A first locking member 38 for fixing the first mounting bracket 32 ​​to the rotating disk 2 is provided between the first mounting bracket 32 ​​and the rotating disk 2, and a second locking member 39 for fixing the second mounting bracket 33 to the rotating disk 2 is provided between the second mounting bracket 33 and the rotating disk 2. Therefore, the polishing belt 31 can be tightened by sliding the first mounting bracket 32 ​​and the second mounting bracket 33, and after adjustment, the first mounting bracket 32 ​​and the second mounting bracket 33 are fixed for use by the first locking member 38 and the second locking member 39.

[0045] Specifically, the first locking member 38 and the second locking member 39 are bolts. The first mounting bracket 32 ​​and the second mounting bracket 33 are both provided with adjustment holes that extend through in the front-back direction. Each adjustment hole is an elongated strip extending along the sliding direction of the first mounting bracket 32 ​​and the second mounting bracket 33. In addition, the rotating disk 2 is provided with screw holes corresponding to the first locking member 38 and the second locking member 39, so that the first locking member 38 and the second locking member 39 pass through the corresponding adjustment holes and are screwed into the corresponding screw holes to press the corresponding first mounting bracket 32 ​​or the second mounting bracket 33 with high strength for fixation.

[0046] In addition, the frame 1 in this embodiment is provided with a placement platform 17 for placing bent pipes, which makes the bending pipe replacement process more efficient.

[0047] Example 2:

[0048] like Figures 6-12 As shown, the present invention also discloses a high-efficiency polishing machine for bent tubes. The structures of Embodiment 2 and Embodiment 1 are the same except for the structure of the rotating frame 42 and the mating mold 44. Therefore, the repeated parts will not be described again.

[0049] In the second embodiment, the rotating frame 42 is also rotatably mounted on the mounting base 41 by being driven by the output shaft of the second motor. The rotation axis of the rotating frame 42 is also arranged vertically. The mating mold 44 also includes a connecting section 441 connected to the rotating frame 42 and a mating fan ring 442 for the bend tube to be fitted. One end of the mating fan ring 442 is also integrally formed and connected to the connecting section 441. The central axis of the mating fan ring 442 is coaxial with the rotation axis of the rotating frame 42.

[0050] Furthermore, unlike Embodiment 1, the rotating frame 42 includes a rotating base 421, an adjusting rod 422, an adjusting locking member 423, and a connecting locking member 424. The rotating base 421 is a horizontally extending elongated strip, with one end rotatably mounted to the mounting base 41. The adjusting rod 422 is rotatably mounted to the other end of the rotating base 421, and its axial direction is vertical. The adjusting locking member 423 is used to fix the adjusting rod 422 to the rotating base 421. The connecting locking member 424... 4 is used to detachably connect the connecting section 441 to the adjusting rod 422. The mating fan ring 442 has a first end face 4421 facing the rotating frame 42. The rotation axis of the rotating seat 421 lies in the plane of the first end face 4421. Furthermore, the maximum radius of the mating fan ring 442 is r1, the minimum radius of the mating fan ring 442 is r2, the distance between the rotation axis of the rotating seat 421 and the central axis of the adjusting rod 422 is s1, and the distance from the central axis of the adjusting rod 422 to the first end face 4421 is... d1, and s12 = ((r1+r2) / 2)2+d12, therefore, the mating molds can be disassembled and assembled by connecting the locking part 424, so that different models of mating fan rings 442 can be replaced to perform different models of pipe bending. Here, s1 is the distance between the rotation axis of the rotating seat 421 and the central axis of the adjusting rod 422. Replacing different mating molds 44 will not affect s1 (which is a constant value). r1 and r2 are the maximum radius and minimum radius of the mating fan rings 442, respectively. The required bending pipe is determined, and the length of d1 is calculated according to s12=((r1+r2) / 2)2+d12 (for designing the mating mold). Under this ratio, as long as it is feasible, regardless of the value of r1 and r2, the mating mold 44 and the adjusting rod 422 can be installed together. By rotating the adjusting rod 422, the central axis of the mating fan ring 442 and the rotation axis of the rotating frame 42 can be adjusted to be coaxial. After the adjustment is completed, the locking part 423 is used to fix the connection.

[0051] Specifically, in this embodiment, the lower axial end of the adjusting rod 422 is provided with a rotating insert 4221 that is rotatably mounted to the rotating seat 421. The rotating seat 421 is provided with a rotating insertion hole 4211 for inserting the rotating insert 4221. In addition, the adjusting locking member 423 is a bolt. The rotating seat 421 is provided with a first locking through hole 4212 located below the rotating insertion hole 4211. The rotating insert 4221 is provided with a corresponding first locking screw hole 4222. The adjusting locking member 423 fixes the adjusted adjusting rod 422 to the rotating seat 421 by passing through the first locking through hole 4212 and threadedly engaging with the first locking screw hole 4222. (During operation, tools or manual fixation of the adjusting rod 422 is required to prevent the adjusting rod 422 from rotating and affecting the displacement of the mating mold 44.)

[0052] Furthermore, in this embodiment, the adjusting rod 422 has a mounting hole 4223 on its axially upward side along the horizontal direction. Correspondingly, the connecting section 441 is provided with a mounting post 4411 inserted into the mounting hole 4223, so that the connection is achieved through the cooperation of the mounting hole 4223 and the mounting post 4411. In addition, the adjusting rod 422 is provided with a second locking through hole 4224 above the mounting hole 4223, and the mounting post 4411 is provided with a corresponding second locking screw hole 4412. The connecting locking member 424 is a bolt, and the adjusting rod 422 of the mating mold 44 is fixed by passing through the second locking through hole 4224 and threadedly engaging with the second locking screw hole 4412.

[0053] Furthermore, in this embodiment, the adjusting rod 422 is provided with a first debugging hole 4225 for the installation of the mounting pin 4411 on the side of the rotating pin 4221. Therefore, after replacing the mating mold 44, the mating mold 44 is first installed in the first debugging hole 4225. At this time, the distance between the mating mold 44 and the rotating seat 421 is relatively close. Therefore, the adjustment makes it more accurate to make the central axis of the mating fan ring 442 and the rotation axis of the rotating frame 42 coaxial. After the adjustment is completed, the adjusting rod 422 is locked, and then the mating mold 44 is transferred to the mounting hole 4223 for locking.

[0054] Furthermore, this embodiment also includes a quick-adjustment component 5, which includes a scale 51, a sliding rod 52, and a third locking member 53. The rotating base 421 has a second adjustment hole 4213 (cylindrical hole) coaxial with the rotation axis of the rotating base 421. One end of the scale 51 has an adjustment post 511 (cylindrical) inserted into the second adjustment hole 4213, and the scale direction of the scale 51 extends radially along the rotation of the rotating base 421. The sliding rod 52 is a sleeve, fitted around the outer circumference of the scale 51 to slide along its scale direction. The third locking member 53 is used to... The sliding rod 52 is fixedly installed on the scale 51. In addition, the sliding rod 52 is provided with a vertically extending adjustment pointer 54 on the side opposite to the adjustment pin 511 along the axial direction. Therefore, 1. When the mating mold 44 needs to be adjusted, the sliding rod 52 can be adjusted so that the scale indication length is r2, thereby rotating the adjustment rod 422 so that the minimum radius of the mating fan ring 442 is against the adjustment pointer to complete the quick adjustment. 2. The mating mold 44 can be judged as qualified by rotating the scale 51 and observing whether the mating mold 44 is against the adjustment pointer 54 at all times. 3. After the adjustment is completed, the quick adjustment component 5 is removed from the rotating seat 421 to prevent the quick adjustment component 5 from affecting the work when the pipe bending polishing machine is working.

[0055] Specifically, a long hole is provided through the lower end of the sliding rod 52, and the length of the long hole extends along the axial direction of the sliding rod 52. A screw hole is provided at the lower end of the scale 51 corresponding to the long hole. The third locking member 53 is a bolt. After the sliding rod 52 is adjusted, the sliding rod 52 is locked by passing through the long hole and engaging with the screw hole thread.

[0056] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
