[0002] A finned tube is a heat exchange element. In order to improve the heat exchange efficiency, fins are usually added to the surface of the heat exchange tube to increase the outer surface area of the heat exchange tube, so as to achieve the purpose of improving the heat exchange efficiency. During the processing of finned tubes, it is necessary to grind the fins at the end of the finned tube according to the use environment.

[0017] In order to make the above objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific implementation manners of the present utility model is provided in conjunction with the accompanying drawings.

[0018] As Figure 1 and Figure 2 shown, the fin tube grinding device provided by the embodiment of the present application has a structure including a frame 1, a front chamfering mechanism 2 and a rear chamfering mechanism 3 arranged symmetrically along the Y direction and disposed thereon, and a conveying mechanism 4 for feeding along the X direction and disposed between the front chamfering mechanism 2 and the rear chamfering mechanism 3. The front chamfering mechanism 2 includes a plurality of cutting components 22 arranged along the X direction and a clamping component 21. The clamping component 21 is used for clamping the fin tube, and the cutting component 22 is used for cutting one end of the fin tube. The clamping component 21 includes a mounting plate 211 disposed on the frame 1, a linear guide rail vertically disposed on the mounting plate 211, a lifting frame 213 slidably disposed on the linear guide rail, a first cylinder 214 for driving the lifting of the lifting frame 213, a first column 215 and a second column 216 arranged vertically and slidably disposed on the lifting frame 213 along the X direction, a cylinder A 217 disposed on the lifting frame 213 for driving the sliding of the first column 215, and a cylinder B 218 for driving the sliding of the second column 216. A first plate 219 fixedly disposed on the first column 215, a second plate 220 fixedly disposed on the second column 216, a block A 221 fixedly disposed at the lower end of the first plate 219, and a block B 222 fixedly disposed at the lower end of the opposite side of the second plate 220 to the first block. The block A 221 is provided with a first groove with a notch facing the second block, and the block B 222 is provided with a second groove symmetric to the first groove.

[0019] In actual use, the finned tubes to be processed are conveyed by the conveying mechanism 4 in a posture extending in the Y direction. For each unit distance of conveyance, the clamping assembly 21 clamps the finned tubes, and then the cutting assembly 22 cuts the tubes. The clamping principle of the clamping assembly 21 is as follows: The lifting frame 213 is driven by the first cylinder 214 to move downward, so that the finned tube to be clamped is located between the block A221 and the block B222. Subsequently, the first column 215 and the second column 216 are respectively driven by the cylinder A217 and the cylinder B218 to move, so that the first block and the second block move towards each other, and the block A221 and the block B222 move towards each other synchronously, clamping the finned tube from both sides. In the clamped state, both sides of the finned tube are respectively located in the first groove and the second groove.

[0020] In the above design, the structural design of the clamping assembly 21 protects the fins through the first groove and the second groove, ensuring that the fins will not deform in the up and down directions when subjected to the clamping force. It can not only effectively clamp the finned tubes, but also ensure that the finned tubes will not be damaged when being clamped.

[0021] Specifically: As Figure 2 shown, the first block is slidably connected to the second column 216, and the second block is slidably connected to the first column 215.

[0022] In actual use, the first column 215 drives the first block to move in the X direction, and the second column 216 drives the second block to move in the X direction.

[0023] In the above design, the movement of the first block can be guided by the second column 216, and the movement of the second block can be guided by the first column 215, ensuring the stability of the movement of the first block and the second block.

[0024] Specifically: As Figure 1 shown, the frame 1 includes a base 17, a first frame 11 fixedly arranged on the base 17 for installing the front chamfering mechanism 2, a second linear guide rail 13 arranged on the base 17 in the Y direction, a second frame 12 slidably arranged on the second linear guide rail 13 for installing the rear chamfering mechanism 3, a lead screw connecting the first frame 11 and the second frame 12, a handwheel 15 arranged on the second frame 12 for driving the lead screw to rotate, and a guide shaft 16 fixedly arranged on the first frame 11 and slidably connected to the second frame 12.

[0025] In actual use, by rotating the handwheel 15, the lead screw drives the second frame 12 to move along the second linear guide rail 13, so that the distance between the second frame 12 and the first frame 11 can be changed, thereby being able to adapt to finned tubes of different lengths.

[0026] In the above design, the structural design and the specific implementation method of the frame 1 are convenient for processing finned tubes of different lengths.

[0027] Specifically: as Figure 3 shown, the conveying mechanism 4 includes a connecting frame 41 disposed between the front end chamfering mechanism 2 and the rear end chamfering mechanism 3, a third linear guide rail 42 disposed on the connecting frame 41 along the X direction, a translation plate 43 slidably disposed on the third linear guide rail 42, a lifting seat 47 disposed on the translation plate 43, a fifth cylinder 46 for driving the lifting of the lifting seat 47, a plurality of pushing and tightening assemblies 44 disposed on the lifting seat 47, and a third cylinder 45 fixedly disposed on the connecting frame 41 for driving the translation plate 43 to slide along the third linear guide rail 42. Each of the pushing and tightening assemblies 44 includes a fixed block 441 fixedly disposed on the lifting seat 47, a fourth cylinder 442 fixedly disposed on the lifting seat 47 and extending along the X direction, and a pushing block 443 disposed at the output end of the fourth cylinder 442.

[0028] During actual use, the third cylinder 45 drives the translation plate 43 to move a unit distance along the third linear guide rail 42, so that the finned tube fixed by the pushing and tightening assembly 44 moves a unit distance synchronously. Then the fifth cylinder 46 drives the lifting seat 47 to rise, so that the finned tube is clamped by the clamping assembly 21, and then the pushing and tightening assembly 44 is loosened. When the pushing and tightening assembly 44 works, the fourth cylinder 442 drives the pushing block 443 to move towards the fixed block 441, so that the finned tube is fixed by the pushing block 443 and the fixed block 441. Thus, it is convenient for the finned tube to move synchronously with the translation plate 43.

[0029] In the above design, the structural design and specific implementation manner of the conveying mechanism 4 can effectively realize the orderly conveying of the finned tube.

[0030] Specifically: as Figure 4 shown, the cutting component 22 includes a fixed seat 201 fixedly disposed on the frame 1, a bearing mounting seat 202 disposed on the fixed seat 201, a ball bearing disposed in the bearing mounting seat 202, a rotating shaft 203 fixedly connected to the inner ring of the ball bearing, a cutting tool 204 coaxially and fixedly connected to one end of the rotating shaft 203, a motor 205 disposed on the fixed seat 201, a driving pulley 207 disposed on the output shaft of the motor 205, a driven pulley 208 disposed at the other end of the rotating shaft 203, and a synchronous belt 206 wound around the driving pulley 207 and the driven pulley 208.

[0031] During actual use, the motor 205 drives the driving pulley 207 to rotate, and the synchronous belt 206 is used to drive the driven pulley 208 to rotate, thereby driving the rotating shaft 203 and the cutting tool 204 to rotate synchronously, so as to realize the grinding of the end of the finned tube.

[0032] In the above design, the structural design and specific implementation manner of the cutting component 22 can effectively realize the grinding of the finned tube.

[0033] For further detailed description, it should be understood that the above are only specific embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
