Description

Technical Field

[0001] This application belongs to the technical field of deburring equipment, and more specifically, relates to a deburring equipment for round holes in honeycomb tubes. Background Technology

[0002] Figure 1 The present invention relates to an 18-hole honeycomb tube made of plastic material, which is used in some existing toys. The 18-hole honeycomb tube 100 includes a honeycomb tube body 101. A total of 18 round holes 102 are formed on the outer wall of the honeycomb tube body 101. All the round holes 102 are arranged in six rows. The six rows of round holes 102 are evenly distributed in a ring around the central axis of the honeycomb tube body 101. Each row has three round holes 102. The three round holes 102 in each row are equally spaced along the central axis of the tube body. Currently, when processing the 18-hole honeycomb tube 100, a drilling tool is first used to roughly machine the round holes 102 on the 18-hole honeycomb tube 100. Because it is rough machining, many small burrs will be formed on the hole wall after the round holes 102 are formed. In order to enable the 18-hole honeycomb tube 100 to be assembled into the toy smoothly and quickly, after the tool has machined the round holes 102 from the honeycomb tube body 101, a brush is also used to drill into the round holes 102. The small burrs on the hole wall of the round holes 102 are removed by forcefully rotating the brush. Currently, the method of removing the burrs on the hole wall of the round holes 102 of the 18-hole honeycomb tube 100 by brush is all done manually, which is not only slow and inefficient, but also very laborious.

[0003] Therefore, developing a highly efficient and labor-saving device that can automatically remove burrs from the walls of the round holes 102 of the 18-hole honeycomb tube 100 has become an urgent problem to be solved. Summary of the Invention

[0004] The purpose of this application is to provide a deburring device for the round holes of honeycomb tubes, so as to solve the problem that in the prior art, the burrs on the hole walls of the round holes of an 18-hole honeycomb tube are removed manually with a brush, which is inefficient and laborious.

[0005] To achieve the above objectives, the technical solution adopted in this application is: to provide a deburring device for round holes in honeycomb tubes, used for deburring 18-hole honeycomb tubes. The 18-hole honeycomb tube includes a honeycomb tube body, on which three groups of holes are evenly distributed in a ring around the central axis of the honeycomb tube body. The three groups of holes are a first group, a second group, and a third group. Each group of holes includes two rows of round holes symmetrical about the central axis of the honeycomb tube body, with three round holes in each row. The honeycomb tube deburring device includes a frame, and a device mounted on the top of the frame:

[0006] A pipe-connecting device is used to hold 18-hole honeycomb tubes transported from outside.

[0007] The discharge chute, located on one side of the connecting pipe device, is used to send out the 18-hole honeycomb tube;

[0008] A tube clamping device is located between the connecting pipe device and the discharge trough. The tube clamping device has three clamping mechanisms for automatically clamping the 18-hole honeycomb tube. The three clamping mechanisms are a first clamping mechanism, a second clamping mechanism, and a third clamping mechanism that are equally spaced along the first direction from the connecting pipe device to the discharge trough.

[0009] A conveying device is located on the same side of the connecting pipe device, the clamping pipe device, and the discharge trough along a second direction perpendicular to the first direction. It is used to simultaneously convey the eighteen-hole honeycomb tubes placed by the connecting pipe device, the first clamping mechanism, the second clamping mechanism, and the third clamping mechanism to the first clamping mechanism, the second clamping mechanism, the third clamping mechanism, and the discharge trough, respectively.

[0010] The deburring device includes three brush mechanisms, namely a first brush mechanism corresponding to the first clamping mechanism, a second brush mechanism corresponding to the second clamping mechanism, and a third brush mechanism corresponding to the third clamping mechanism. The first brush mechanism deburrs the first hole group of the 18-hole honeycomb tube held by the first clamping mechanism, the second brush mechanism deburrs the second hole group of the 18-hole honeycomb tube held by the second clamping mechanism, and the third brush mechanism deburrs the third hole group of the 18-hole honeycomb tube held by the third clamping mechanism.

[0011] This invention employs a conveying device to repeatedly retrieve 18-hole honeycomb tubes from a connecting device, a first clamping mechanism, a second clamping mechanism, and a third clamping mechanism. The retrieved 18-hole honeycomb tubes are then transported to the first clamping mechanism, the second clamping mechanism, the third clamping mechanism, and a discharge chute, respectively. Three brush mechanisms are provided, corresponding to the first, second, and third clamping mechanisms. During the transition from the tube-retrieval state to the tube-releasing state, the first brush mechanism deburrs the first group of holes in the 18-hole honeycomb tubes held by the first clamping mechanism, the second brush mechanism deburrs the second group of holes in the 18-hole honeycomb tubes held by the second clamping mechanism, and the third brush mechanism deburrs the second group of holes in the 18-hole honeycomb tubes held by the second clamping mechanism. The mechanism can deburr the third group of holes in the 18-hole honeycomb tube held by the third clamping mechanism. Due to the transporting action of the transport device, each 18-hole honeycomb tube can pass through the first clamping mechanism, the second clamping mechanism and the third clamping mechanism in sequence. Thus, each 18-hole honeycomb tube can pass through the first brush mechanism to deburr the first group of holes, the second brush mechanism to deburr the second group of holes and the third brush mechanism to deburr the third group of holes in sequence. This achieves automated deburring of all the round holes of the entire 18-hole honeycomb tube, eliminating the need for manual removal of burrs from all the round holes of the 18-hole honeycomb tube. It is highly efficient and labor-saving. Moreover, the structural design of this invention can achieve deburring of the round holes of three 18-hole honeycomb tubes at the same time, further improving efficiency.

[0042] Please see Figures 1 to 10 This invention discloses a deburring device for round holes in a honeycomb tube, used to deburr an 18-hole honeycomb tube 100. The 18-hole honeycomb tube 100 includes a honeycomb tube body 101, on which three groups of holes are evenly distributed in a ring around the central axis of the honeycomb tube body 101. The three groups of holes are a first group of holes, a second group of holes, and a third group of holes. Each group of holes includes two rows of round holes 102 symmetrical about the central axis of the honeycomb tube body 101, with three round holes 102 in each row.

[0043] like Figure 1 As shown, the deburring equipment for round holes of honeycomb tubes includes a frame 10, and a pipe connecting device 20, a pipe clamping device 30, a conveying device 60, a deburring device, and a discharge chute 80, all disposed on the top of the frame 10.

[0044] The connecting device 20 is used to hold the 18-hole honeycomb tubes 100 transported from outside; the discharge chute 80 is located on one side of the connecting device 20 and is inclined downward along the first direction from the connecting device 20 to the discharge chute 80, used to transport the 18-hole honeycomb tubes 100 with burrs removed to a collection box or other equipment; the clamping device 30 is located between the connecting device 20 and the discharge chute 80, and the clamping device 30 has three clamping mechanisms for automatically clamping the 18-hole honeycomb tubes 100, namely a first clamping mechanism 50a, a second clamping mechanism 50b, and a third clamping mechanism 50c, which are equally spaced along the first direction; the conveying device 60 is located on the same side of the connecting device 20, the clamping device 30, and the discharge chute 80 along a second direction perpendicular to the first direction, used to simultaneously convey the connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. b. The 18-hole honeycomb tube 100 placed by the third clamping mechanism 50c is respectively transported to the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c and the discharge trough 80; the deburring device includes three brush mechanisms, namely the first brush mechanism 70a corresponding to the first clamping mechanism 50a, the second brush mechanism 70b corresponding to the second clamping mechanism 50b and the third brush mechanism 70c corresponding to the third clamping mechanism 50c. The first brush mechanism 70a deburrs the first hole group of the 18-hole honeycomb tube 100 held by the first clamping mechanism 50a, the second brush mechanism 70b is used to deburr the second hole group of the 18-hole honeycomb tube 100 held by the second clamping mechanism 50b, and the third brush mechanism 70c is used to deburr the third hole group of the 18-hole honeycomb tube 100 held by the third clamping mechanism 50c.

[0045] The working principle of the honeycomb tube round hole deburring device of the present invention is as follows:

[0046] The conveying device 60 has a tube-picking state and a tube-laying state, and the conveying device 60 switches back and forth between the tube-picking state and the tube-laying state. When the conveying device 60 switches to the tube-picking state, the conveying device 60 picks up the 18-hole honeycomb tube 100 from the tube-connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. After picking up the tube, the conveying device 60 switches to the tube-laying state and places the tube on the tube-connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. The 18-hole honeycomb tubes 100 obtained by 0c are placed on the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the discharge chute 80, respectively. After placement, the device is switched back to the tube-retrieving state. During the process of the conveying device 60 switching from the tube-placing state to the tube-retrieving state, the first brush mechanism 70a, the second brush mechanism 70b, and the third brush mechanism 70c simultaneously perform deburring work. The first brush mechanism 70a deburrs the 18-hole honeycomb tubes 100 on the first clamping mechanism 50a. The first brush mechanism 70a, the second brush mechanism 70b, and the third brush mechanism 70c deburr the second group of holes on the eighteen-hole honeycomb tube 100 on the third clamping mechanism 50b. During the transition from the tube-picking state to the tube-releasing state, the first brush mechanism 70a, the second brush mechanism 70b, and the third brush mechanism 70c simultaneously stop working. This process is repeated continuously through the machine. When the 18-hole honeycomb tubes are supplied to the connecting device 20 by means of a robotic arm or manual operation, each 18-hole honeycomb tube 100 sequentially passes through the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. Then, it undergoes deburring of the first, second, and third hole groups by the first brushing mechanism 70a, the second brushing mechanism 70b, and the third brushing mechanism 70b, respectively. Finally, the 18-hole honeycomb tube 100 after deburring is transported to the discharge trough 80. When the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c all hold 18-hole honeycomb tubes 100, the conveying device 60 can transport four 18-hole honeycomb tubes 100 at a time. In this case, the equipment of the present invention can simultaneously perform deburring work on three 18-hole honeycomb tubes, resulting in very high efficiency.

[0047] This invention employs a conveying device 60 to repeatedly retrieve 18-hole honeycomb tubes 100 from the connecting pipe device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. The 18-hole honeycomb tubes 100 retrieved from these mechanisms are then transported to the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the discharge trough 80, respectively. Three brush mechanisms are also provided, corresponding to the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c. During the transition of the conveying device 60 from the tube-releasing state to the tube-retrieving state, the first brush mechanism 70a deburrs the first group of holes in the 18-hole honeycomb tubes 100 held by the first clamping mechanism 50a, and the second brush mechanism 70b deburrs the second group of holes in the 18-hole honeycomb tubes 100 held by the second clamping mechanism 50b. In operation, the third brush mechanism 70c can deburr the third group of holes of the 18-hole honeycomb tube 100 held by the third clamping mechanism 50c. Due to the transporting action of the transport device 60, each 18-hole honeycomb tube 100 can pass through the first clamping mechanism 50a, the second clamping mechanism 50b and the third clamping mechanism 50c in sequence. Therefore, each 18-hole honeycomb tube 100 can pass through the first brush mechanism 70a for deburring the first group of holes, the second brush mechanism 70b for deburring the second group of holes and the third brush mechanism 70c for deburring the third group of holes in sequence. This achieves automated deburring of all the round holes 102 of the entire 18-hole honeycomb tube 100 without the need for manual removal of the burrs from all the round holes 102 of the 18-hole honeycomb tube 100. This is highly efficient and labor-saving. Moreover, the structural design of the device of the present invention can achieve deburring of the round holes 102 of three 18-hole honeycomb tubes 100 at the same time, further improving efficiency.

[0048] In one embodiment, such as Figure 2 As shown, the tube feeding device 20 includes a tube feeding support frame 40 fixed on the frame 10, a tube feeding drive cylinder 22 mounted on the tube feeding support frame 40, a first connecting vertical plate 23 connecting the output shaft of the tube feeding drive cylinder 22, a tube feeding rack 25 located on the side of the first connecting vertical plate 23 near the transport device 60, and a second connecting vertical plate 24 connecting the first connecting vertical plate 23 and the tube feeding rack 25. The tube feeding rack 25 has a tube feeding cavity for placing the 18-hole honeycomb tube 100. A positioning post 28 located in the tube feeding cavity is installed on the tube feeding rack 25. The central axis of the positioning post 28 is parallel to the second direction. The positioning post 28 is used to pass through a pair of circular holes 102 of the 18-hole honeycomb tube 100 that are symmetrical about the central axis of the honeycomb tube body 101, so that the 18-hole honeycomb tube 100 will not move in the left-right and up-down directions when deburring, ensuring that the transport device 60 can accurately pick up the 18-hole honeycomb tube 100 from the tube feeding device 20.

[0049] Furthermore, the tube placement frame 25 includes a first frame 26 and a second frame 27 located above the first frame 26; the first frame 26 includes a first mounting vertical plate 261 mounted on the second connecting vertical plate 24 and a tube placement plate 262 connected to the first mounting vertical plate 261, the tube placement plate 262 being used to place the 18-hole honeycomb tube 100; the second frame 27 includes a second mounting vertical plate 271 detachably mounted on the second connecting vertical plate 24; a tube placement cavity is formed between the perpendicular tube placement plate 262 and the second mounting vertical plate 271; the positioning post 28 is detachably mounted on the second mounting vertical plate 271.

[0050] The first mounting vertical plate 261 is detachably mounted on the second connecting vertical plate 24. For example, as... Figure 3 As shown, the first mounting plate 261 has a long mounting hole 263 extending vertically. The first mounting plate 41 is detachably mounted to the second connecting plate 24 through the long mounting hole 263 and screws. The long mounting hole 263 can change the height position of the tube-laying plate 262 of the first frame 26 in the vertical direction, so that the distance between the tube-laying plate 262 and the positioning post 28 can be changed according to the size specifications of the 18-hole honeycomb tube 100. This makes the connecting device 20 applicable to various sizes and specifications of 18-hole honeycomb tubes 100, improving the applicability of the connecting device 20.

[0051] In one embodiment, such as Figure 4 The clamping device 30 includes a clamping support frame 40 and three clamping mechanisms. The clamping support frame 40 is mounted on the frame 10. The three clamping mechanisms are a first clamping mechanism 50a, a second clamping mechanism 50b, and a third clamping mechanism 50c arranged sequentially along the first direction from the pipe connecting device 20 to the discharge trough 80. Each clamping mechanism includes an upper clamping component 51 for pressing the top end of the 18-hole honeycomb tube 100 and a lower clamping component 56 for pressing the bottom end of the 18-hole honeycomb tube 100. The upper clamping component 51 is mounted on the clamping support frame 40, and the lower clamping component 56 is located below the upper clamping component 51 and is mounted on the frame 10. When the 18-hole honeycomb tube 100 is transported to the clamping mechanism, the upper clamping component 51 and the lower clamping component 56 of the clamping mechanism automatically press against the top and bottom ends of the 18-hole honeycomb tube 100, respectively, to clamp the 18-hole honeycomb tube 100, which facilitates the brush mechanism to deburr the round holes 102 of the 18-hole honeycomb tube 100. After the transport device 60 grabs the 18-hole honeycomb tube 100, the upper clamping component 51 and the lower clamping component 56 automatically move away from the top and bottom ends of the 18-hole honeycomb tube 100, so that the transport device 60 can move the 18-hole honeycomb tube 100 away from the clamping mechanism. Moreover, the clamping mechanism of this clamping method is also suitable for clamping 18-hole honeycomb tubes 100 of different sizes and specifications, and has good applicability.

[0052] The upper clamping assembly 51 includes an upper clamping cylinder 52, an upper push rod 53 located below the upper clamping cylinder 52, and an upper pressure block 54. The top end of the upper push rod 53 is connected to the output shaft of the upper clamping cylinder 52, and the bottom end of the upper push rod 53 is detachably fitted with the upper pressure block 54. Figure 5 The upper pressure block 54 includes an upper positioning rod 541 and an upper pressing protrusion ring 542 disposed on the outer side wall of the upper positioning rod 541. The upper pressing protrusion ring 542 is located in the middle position of the upper positioning rod 541 and is coaxially arranged with the upper positioning rod 541. The upper pressing protrusion ring 542 is located below the upper push rod 53 and is used to press on the top of the 18-hole honeycomb tube 100. The part of the upper positioning rod 541 above the upper pressing protrusion ring 542 is inserted into the bottom end of the upper positioning rod 541. The part of the upper positioning rod 541 below the upper pressing protrusion ring 542 matches the inner diameter of the top end of the 18-hole honeycomb tube 100 and is used to insert into the top end of the 18-hole honeycomb tube 100 to achieve positioning of the 18-hole honeycomb tube 100.

[0053] Optionally, the upper pressure block 54 is detachably mounted on the bottom end of the upper push rod 53 by screws. The screw head is positioned on the bottom side of the positioning rod 541. The screw shank passes through the upper positioning rod 541 along the axial direction of the upper positioning rod 541 and enters into the bottom end of the upper push rod 53, and is threadedly connected to the upper push rod 53.

[0054] Furthermore, the clamping support frame 40 includes a first mounting plate 41, a second mounting plate 42 located below the second mounting plate 42, a first support plate 43 connecting the first mounting plate 41 and the second mounting plate 42, a second support plate 44 connecting the frame 10 and the second mounting plate 42, and a first upper guide cylinder 45 mounted on the second mounting plate 42; the upper clamping cylinder 52 is mounted on the top of the first mounting plate 41; the number of first upper guide cylinders 45 is equal to that of upper clamping components 51, and they are arranged in a one-to-one correspondence; the first upper guide cylinder 45 is sleeved on the upper push rod 53, the bottom end of the first upper guide cylinder 45 is mounted on the second mounting plate 42, and the top end is located between the first mounting plate 41 and the second mounting plate 42; each upper clamping component 51 also includes a second upper guide cylinder 55 corresponding to the first upper guide cylinder 45, the second upper guide cylinder 55 is fixed on the upper push rod 53, and can be slidably sleeved on the first upper guide cylinder 45. The first upper guide cylinder 45 and the second upper guide cylinder 55 are configured to guide the movement of the upper push rod 53, enabling it to make stable linear movements. On the other hand, the second upper guide cylinder 55 can limit the travel of the upper push rod 53. When the top of the second upper guide cylinder 55 abuts against the first mounting plate 41, it can limit the upper travel of the upper push rod 53. When the bottom of the second upper guide cylinder 55 abuts against the second mounting plate 42, it can limit the lower travel of the upper push rod 53.

[0055] Optional, such as Figure 5As shown, the upper push rod 53 includes a connecting part 531 and a guide part 532 connected sequentially from top to bottom. The connecting part 531 is inserted into the output shaft of the upper clamping cylinder 52 and is threadedly engaged with the output shaft of the clamping cylinder. The cross-sectional dimension of the guide part 532 is larger than that of the connecting part 531. The guide part 532 can slide through the first upper guide cylinder 45. The outer diameter of the guide part 532 matches the inner diameter of the first upper guide cylinder 45 so that the upper push rod 53 can make a stable linear movement under the guidance of the first upper guide cylinder 45. The end of the guide part 532 away from the connecting part 531 can be detachably connected to the upper pressure block 54.

[0056] The second upper guide cylinder 55 includes a straight cylindrical upper cylinder body 551 and an upper cylinder cover plate 552 that seals the top of the upper cylinder body 551. The upper cylinder body 551 is sleeved outside the first upper guide cylinder 45 and is located between the first mounting plate 41 and the second mounting plate 42. The upper cylinder cover plate 552 is clamped between the output shaft of the upper clamping cylinder 52 and the guide portion 532 of the upper push rod 53 so that the second upper guide cylinder 55 can be fixed on the upper push rod 53.

[0057] In one embodiment, the lower clamping assembly 56 includes a lower clamping cylinder 57 and a lower pressing block 58 located above the lower clamping cylinder 57. The lower pressing block 58 is detachably mounted on the output shaft of the lower clamping cylinder 57 and is used to press against the bottom end of the 18-hole honeycomb tube 100 under the push of the lower clamping cylinder 57. This invention achieves a secure clamping of the 18-hole honeycomb tube 100 by simultaneously pushing the upper pressing block 54 against the top end of the 18-hole honeycomb tube 100 with the upper clamping cylinder 52 and the lower clamping cylinder 57 pushing the lower pressing block 58 against the bottom end of the 18-hole honeycomb tube 100.

[0058] The lower pressing block 58 includes a lower positioning rod 581 and a lower pressing protrusion ring 582 disposed on the outer side wall of the lower positioning rod 581. The lower pressing protrusion ring 582 is coaxially arranged with the lower positioning rod 581 and is located in the middle position of the lower positioning rod 581. The lower pressing protrusion ring 582 is located above the output shaft 571 of the lower clamping cylinder and is used to press on the bottom end of the 18-hole honeycomb tube 100. The part of the lower positioning rod 581 located below the lower pressing protrusion ring 582 is inserted into the output shaft of the lower clamping cylinder 571. The part of the lower positioning rod 581 located above the lower pressing protrusion ring 582 matches the inner diameter of the bottom end of the 18-hole honeycomb tube 100 and is used to insert into the bottom end of the 18-hole honeycomb tube 100 to achieve positioning of the 18-hole honeycomb tube 100. When the upper pressure block 54 and the lower pressure block 58 press on the top and bottom of the 18-hole honeycomb tube 100 respectively, the upper positioning rod 541 located below the upper pressing protrusion ring 542 and the lower positioning rod 581 located above the lower pressing protrusion ring 582 are respectively inserted into the top and bottom of the 18-hole honeycomb tube 100 to prevent the 18-hole honeycomb tube 100 from moving horizontally when its round hole 102 is deburred, thus ensuring that the deburring work of the 18-hole honeycomb tube 100 can be carried out smoothly.

[0059] Optionally, the lower pressure block 58 can be detachably mounted to the output shaft of the lower clamping cylinder 57 by screws. Specifically, as shown... Figure 5 As shown, the screw head presses against the upper side of the lower positioning rod 581, and the screw shank passes through the lower positioning rod 581 along the axial direction of the lower positioning rod 581 and extends into the lower clamping cylinder output shaft 571, and is threadedly connected to the lower clamping cylinder output shaft 571.

[0060] Optionally, a lower guide protrusion 572 protrudes from the top side of the lower clamping cylinder 57, through which the output shaft 571 of the lower clamping cylinder passes. The lower pressing block 58 also includes a shaft protection structure 59 for protecting the output shaft 571 of the lower clamping cylinder. The shaft protection structure 59 includes a lower guide cylinder 591 sleeved outside the lower guide protrusion 572 and a lower sealing plate 592 connecting the lower guide cylinder 591 and the lower guide protrusion 572. In this application, the length of the lower guide cylinder 591 is set such that when the pressing block 58 is pressed against the bottom end of the 18-hole honeycomb tube 100, the lower guide cylinder 591 will not detach from the lower guide protrusion 572. In this invention, the shaft protection structure 59 composed of the lower guide cylinder 591 and the lower sealing plate 592 ensures that the output shaft of the lower clamping cylinder 57 is not exposed, effectively protecting the output shaft of the lower clamping cylinder 57 and extending the service life of the lower clamping cylinder 57.

[0061] In one embodiment, such as Figure 6The conveying device 60 includes four pipe-carrying clamping mechanisms and a pipe-carrying drive mechanism 62 connecting the four pipe-carrying clamping mechanisms. The four pipe-carrying clamping mechanisms are a first pipe-carrying clamping mechanism 61a, a second pipe-carrying clamping mechanism 61b, a third pipe-carrying clamping mechanism 61c, and a fourth pipe-carrying clamping mechanism 61d, which are arranged at equal intervals along a first direction from the pipe-connecting device 20 to the discharge trough 80. The pipe-carrying drive mechanism 62 is used to drive the first pipe-carrying clamping mechanism 61a, the second pipe-carrying clamping mechanism 61b, the third pipe-carrying clamping mechanism 61c, the fourth pipe-carrying clamping mechanism 61d, the fifth pipe-carrying clamping mechanism 61d, the sixth pipe-carrying clamping mechanism 61d, the seventh pipe-carrying clamping mechanism 61d, the eighth pipe-carrying clamping mechanism 61d, the ninth pipe-carrying clamping mechanism 61d, the eleventh ... The pipe-handling clamping mechanism 61c and the fourth pipe-handling clamping mechanism 61d simultaneously pick up the eighteen-hole honeycomb tube 100 from the pipe-connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b and the third clamping mechanism 50c, respectively, and then transport the eighteen-hole honeycomb tubes picked up from the pipe-connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b and the third clamping mechanism 50c to the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c and the discharge trough 80, respectively. That is, the first pipe-handling clamping mechanism 61a takes the 18-hole honeycomb tube 100 from the connecting pipe device 20 and moves it to the first clamping mechanism 50a; the second pipe-handling clamping mechanism 61b takes the 18-hole honeycomb tube 100 from the first clamping mechanism 50a and moves it to the second clamping mechanism 50b; the third pipe-handling clamping mechanism 61c takes the 18-hole honeycomb tube 100 from the second clamping mechanism 50b and moves it to the third clamping mechanism 50c; and the fourth pipe-handling clamping mechanism 61d takes the 18-hole honeycomb tube 100 from the third clamping mechanism 50c and moves it to the discharge trough 80. These actions occur simultaneously, and the round holes 102 of the 18-hole honeycomb tubes that are finally transported to the discharge trough 80 have all been deburred.

[0062] The first pipe-handling clamping mechanism 61a, the second pipe-handling clamping mechanism 61b, and the third pipe-handling clamping mechanism 61c all have the same structure. They all include two grippers 612 and a gripper drive cylinder 611 connecting the two grippers 612. The gripper drive cylinder 611 is used to drive the two grippers 612 to clamp the 18-hole honeycomb tube 100. The two grippers 612 have arc-shaped grooves 6121 that match the 18-hole honeycomb tube 100 on the side facing each other, so as to increase the contact area between the two grippers 612 and the 18-hole honeycomb tube 100, so that the two grippers 612 can clamp the 18-hole honeycomb tube 100 more firmly.

[0063] Preferred, such as Figure 2As shown, the second frame 27 of the tube placement rack 25 of the tube placement device 20 also includes two limiting plates 272 connected to the second mounting vertical plate 271. The limiting plates 272 extend from the second mounting vertical plate 271 in the second direction. The two limiting plates 272 are located on opposite sides of the gripper 612 in the vertical direction. The distance between the two limiting plates 272 is equal to the width of the gripper 612, so that when the two grippers 612 approach the 18-hole honeycomb tube 100 placed on the tube placement rack 25 to grasp it, the gripper 612 corresponding to the two limiting plates 272 can extend into the space between the two limiting plates 272. The two limiting plates 272 can guide the gripper 612 as the gripper approaches the 18-hole honeycomb tube 100, so that the two grippers 612 can stably grasp the 18-hole honeycomb tube 100 placed on the tube placement rack 25.

[0064] In one embodiment, such as Figure 6 As shown, the pipe-carrying drive mechanism 62 includes a first transport mounting plate 621, a second transport mounting plate 622 located below the first transport mounting plate 621, a first transport cylinder 623 mounted on the second transport mounting plate 622, and a second transport cylinder 624 mounted on the frame 10. Four pipe-carrying clamping mechanisms are mounted on the top side of the first transport mounting plate 621. The second transport mounting plate 622 is slidably connected to the first transport mounting plate 621 and the frame 10. The first transport cylinder 623 is connected to the first transport mounting plate 621 and is used to drive the first transport mounting plate 621 to move back and forth along a first direction with the four pipe-carrying clamping mechanisms, so that the four pipe-carrying clamping mechanisms can move at the first working position and the second working position. The four pipe-handling clamping mechanisms move back and forth between the positions. When the four pipe-handling clamping mechanisms are in the first position, the positions of the first pipe-handling clamping mechanism 61a, the second pipe-handling clamping mechanism 61b, the third pipe-handling clamping mechanism 61c, and the fourth pipe-handling clamping mechanism 61d correspond to the positions of the pipe-connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c, respectively. When the four pipe-handling clamping mechanisms are in the second position, the positions of the first pipe-handling clamping mechanism 61a, the second pipe-handling clamping mechanism 61b, the third pipe-handling clamping mechanism 61c, and the fourth pipe-handling clamping mechanism 61d correspond to the positions of the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the discharge chute 80, respectively. The output shaft of the second transport cylinder 624 is connected to the second transport mounting plate 622, which drives the second transport mounting plate 622 to move the four tube clamping mechanisms closer to or further away from the tube clamping device 30 in the second direction. This allows the tube clamping mechanisms to release and move away from the eighteen-hole honeycomb tube 100 after transporting it to the clamping mechanism, so that the tube clamping mechanisms do not obstruct the deburring device from deburring the round holes 102 of the eighteen-hole honeycomb tube 100.

[0065] The specific working principle of the conveying device 60 is as follows: Initially, the first pipe clamping mechanism 61a, the second pipe clamping mechanism 61b, the third pipe clamping mechanism 61c, and the fourth pipe clamping mechanism 61d are located at the first working position, that is, the positions of the first pipe clamping mechanism 61a, the second pipe clamping mechanism 61b, the third pipe clamping mechanism 61c, and the fourth pipe clamping mechanism 61d correspond to the positions of the pipe connecting device 20, the first clamping mechanism 50a, the second clamping mechanism 50b, and the third clamping mechanism 50c, respectively, and are far away from each other. During operation, the first transport cylinder 623 first drives the first pipe clamping mechanism 61a, the second pipe clamping mechanism 61b, the third pipe clamping mechanism 61c, and the fourth pipe clamping mechanism 61d to the second working position via the first transport mounting plate 621. That is, the first pipe clamping mechanism 61a, the second pipe clamping mechanism 61b, the third pipe clamping mechanism 61c, and the fourth pipe clamping mechanism 61d move to the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the fourth clamping mechanism 61d respectively. The positions of the three clamping mechanisms 50c and the discharge chute 80 correspond to each other; then the second transport cylinder 624 drives the second mounting plate 42 to move the first pipe clamping mechanism 61a, the second pipe clamping mechanism 61b, the third pipe clamping mechanism 61c, and the fourth pipe clamping mechanism 61d along the second direction to approach the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the discharge chute 80 respectively. If the pipe clamping mechanism of the corresponding clamping mechanism holds an eighteen-hole honeycomb... The clamping mechanism will transfer the 18-hole honeycomb tube 100 to the clamping mechanism for clamping. If the corresponding tube-moving clamping mechanism of the discharge trough 80 is holding the 18-hole honeycomb tube 100, the tube-moving clamping mechanism will release the 18-hole honeycomb tube 100, and the 18-hole honeycomb tube 100 will automatically fall into the discharge trough 80. After the transfer of the 18-hole honeycomb tube 100 is completed, the second transport cylinder 624 drives the second mounting plate 42 to carry the first tube-moving clamping mechanism 61a and the second tube-moving clamping mechanism 61. b. The third pipe-handling clamping mechanism 61c and the fourth pipe-handling clamping mechanism 61d move away from the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c and the discharge chute 80 along the second direction to a designated distance position. Then, the first transport cylinder 623 drives the first mounting plate 41 to move the first pipe-handling clamping mechanism 61a, the second pipe-handling clamping mechanism 61b, the third pipe-handling clamping mechanism 61c and the fourth pipe-handling clamping mechanism 61d back to the first work station.Repeating the above actions will cause each 18-hole honeycomb tube 100 to be sequentially transported to the first clamping mechanism 50a, the second clamping mechanism 50b, the third clamping mechanism 50c, and the discharge trough 80. When the 18-hole honeycomb tube 100 is on the first clamping mechanism 50a, it will undergo deburring of the first hole group by the first brush mechanism 70a. When the 18-hole honeycomb tube 100 is transferred to the second clamping mechanism 50b, it will undergo deburring of the second hole group by the second brush mechanism 70b. When the 18-hole honeycomb tube 100 is transferred to the third clamping mechanism 50c, it will undergo deburring of the third hole group by the third brush mechanism 70c. When the 18-hole honeycomb tube 100 is transferred to the discharge trough 80, all the round holes 102 have been deburred.

[0066] The first brush mechanism 70a, the second brush mechanism 70b, and the third brush mechanism 70c all have the same structure, such as Figure 7 and Figure 8 As shown, each component includes a first brush drive cylinder 71 mounted on the top side of the frame 10, a first push frame 721 connected to the output shaft of the first brush drive cylinder 71, a motor 73 mounted on the first push frame 721, a second brush drive cylinder 74 mounted on the first push frame 721, a second push frame 722 connected to the second brush drive cylinder 74, a third push frame 723 connected to the second push frame, three rotating shafts, three brushes 76, three gears 77, and a connecting cylinder 78 fixedly connected to the output shaft of the motor 73; the three rotating shafts, from top to bottom, are a first rotating shaft 75a, a second rotating shaft 75b, and a third rotating shaft 75c, and are all mounted on the third push frame 723; the three brushes 76 are respectively mounted on the first rotating shaft 75a, the second rotating shaft 75b, and the third rotating shaft 75c facing the clamping mechanism. At one end, three brushes 76 correspond to three pairs of circular holes 102 symmetrical about the central axis of the honeycomb tube body 101, respectively, so that the three brushes 76 can be inserted into the three pairs of circular holes 102 symmetrical about the central axis of the honeycomb tube body 101 under the drive of the first brush drive cylinder 71 and the second brush drive cylinder 74; three gears 77 are respectively installed on the ends of the first rotating shaft 75a, the second rotating shaft 75b and the third rotating shaft 75c away from the brushes 76, and the three gears 77 mesh sequentially from top to bottom. The end of the second rotating shaft 75b where the gears 77 are installed is connected to a connecting post 79, which is inserted into the connecting cylinder 78. The connecting cylinder 78 and the connecting post 79 are slidably connected by a matching elongated protrusion 781 and a long sliding groove 791, for example, as Figure 10As shown, a long protrusion 781 is provided on the inner wall of the connecting cylinder 78, extending along the axial direction of the connecting cylinder 78, and a long sliding groove 791 is provided on the connecting column 79. The cooperation of the long protrusion 781 and the long sliding groove 791 enables the motor 73 to drive the second rotating shaft 75b to rotate through the connecting cylinder 78 and the connecting column 79, and also allows the second rotating shaft 75b to slide relative to the connecting cylinder 78, thereby enabling the second brush drive cylinder 74 to drive the second push frame 722 to move along the axial direction of the connecting cylinder 78 with the three brushes 76. The three brushes 76 of the first brush mechanism 70a face the first clamping mechanism 50a and are used to deburr the round holes 102 of the first hole group of the 18-hole honeycomb tube 100. The three brushes 76 of the second brush mechanism 70b face the second clamping mechanism 50b and are used to deburr the round holes 102 of the second hole group of the 18-hole honeycomb tube 100. The three brushes 76 of the third deburring mechanism face the third clamping mechanism 50c and are used to deburr the round holes 102 of the third hole group of the 18-hole honeycomb tube 100.

[0067] The working principle of the brush mechanism is as follows: When the clamping mechanism holds the 18-hole honeycomb tube 100 transported by the tube-moving clamping mechanism, and the tube-moving clamping mechanism is far away from the clamping mechanism, the three brush mechanisms work simultaneously, namely, the first brush mechanism 70a, the second brush mechanism 70b, and the third brush mechanism 70c work simultaneously. The first brush drive cylinder 71 of the brush mechanism first works to drive the three brushes 76 to approach the 18-hole honeycomb tube 100 held by the corresponding clamping mechanism. After approaching, the first brush drive cylinder 71 stops working, and the motor 73 works. The motor 73 drives the second rotating shaft 75b to rotate through the connecting cylinder 78 and the connecting shaft 79. The rotating second rotating shaft 75b... The gear 77 mounted on it drives two other gears 77 to rotate the first rotating shaft 75a and the third rotating shaft 75c respectively. Thus, the first rotating shaft 75a, the second rotating shaft 75b, and the third rotating shaft 75c all rotate. The rotating first rotating shaft 75a, the second rotating shaft 75b, and the third rotating shaft 75c respectively drive the three brushes 76 to rotate. Subsequently, the second brush drive cylinder 74 operates, driving the three rotating brushes 76 to insert into three pairs of symmetrical circular holes 102 about the central axis of the honeycomb tube body 101 in one hole group of the eighteen-hole honeycomb tube 100. That is, one brush 76 is inserted into a pair of symmetrical circular holes 102. Driven by the second brush drive cylinder 74, the three brushes 76 move back and forth along the central axis of the inserted circular holes 102. The three brushes 76 of the first brush mechanism 70a are respectively inserted into the three pairs of circular holes 102 symmetrical about the central axis of the honeycomb tube body 101 in the first hole group; the three brushes 76 of the second brush mechanism 70b are respectively inserted into the three pairs of circular holes 102 symmetrical about the central axis of the honeycomb tube body 101 in the second hole group; and the three brushes 76 of the third brush mechanism 70c are respectively inserted into the three pairs of circular holes 102 symmetrical about the central axis of the honeycomb tube body in the third hole group. When the first tube clamping mechanism 61a, the second tube clamping mechanism 61b, the third tube clamping mechanism 61c, and the fourth tube clamping mechanism 61d return to the first working position, the motor 73 stops working, and the first brush drive cylinder 73 and the second brush drive cylinder 74 drive the three brushes 76 away from the eighteen-hole honeycomb tube 100 and return to their original positions.

[0068] To ensure that the first push frame 721 can make stable linear motion, the first push frame 721 and the frame 10 are slidably connected by matching guide rails and guide grooves.

[0069] In this embodiment, as Figure 9As shown, the brush 76 includes a brush post 761, a bristle tube 762, and bristles 763. One end of the brush post 761 is detachably mounted on a rotating shaft (first rotating shaft 75a, second rotating shaft 75b, or third rotating shaft 75c). The bristle tube 762 is sleeved on the other end of the brush post 761 and threadedly connected to the brush post 761. This arrangement allows the entire brush 76 to be replaced only when the bristles 763 are severely damaged, without replacing the entire brush 76. Only the structure consisting of the bristle tube 762 and the bristles 763 needs to be replaced. This reduces replacement costs. The bristles 763 are evenly distributed outside the bristle tubes 762. The number of bristle tubes 762 can be one or several. If there are several, the bristle tubes 762 are arranged sequentially along the central axis of the brush column 761. By setting the bristle tubes 762 to several, when a part of the bristles 763 of the brush 76 is severely damaged, it is only necessary to replace the structure consisting of the damaged bristles 763 and the bristle tubes 762 corresponding to the damaged bristles 763, which can further reduce replacement costs.

[0070] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
