[0031] The present invention is further described below in conjunction with the accompanying drawings, and embodiments of the present invention are given in conjunction with the accompanying drawings.

[0032] Example 1

[0033] A burr cleaning device for the inner wall of an exhaust pipe of a new energy vehicle comprises a support frame 1, a grinding roller 2, a mounting frame 3, a driving mechanism 4 and a limiting mechanism 5, please refer to Figure 1-Figure 6 As shown, a mounting frame 3 is installed on the left side of the outer top of the support frame 1 by welding, and three groups of symmetrical positioning blocks are arranged at intervals on the right side of the upper inner part of the mounting frame 3. The operator can place the exhaust pipe on the mounting frame 3, and a driving mechanism 4 is installed on the support frame 1. The driving mechanism 4 is used to provide power. Three groups of grinding rollers 2 are installed on the driving mechanism 4, and the number of grinding rollers 2 in each group is three. When the grinding rollers 2 rotate, the grinding rollers 2 can remove burrs on the inner wall of the exhaust pipe. A limiting mechanism 5 is installed on the left part of the support frame 1, and the driving mechanism 4 moves to the left to contact with the limiting mechanism 5. When the limiting mechanism 5 moves downward, the limiting mechanism 5 can press and fix the exhaust pipe.

[0034] The driving mechanism 4 includes a sliding frame 41, a guide rail 42, a driving motor 43, a gear 44, a rotating shaft 45, a transmission assembly 46, a mounting plate 47, a mounting plate 48 and a contact frame 49, see Figure 1 and Figure 4 As shown, a guide rail 42 is installed on the right side of the bottom of the support frame 1 symmetrically through bolt connection, a sliding frame 41 is slidably connected between the front and rear guide rails 42, and a contact frame 49 is fixedly connected to the left side of the top of the sliding frame 41 symmetrically. When the contact frame 49 moves to the left and contacts the limit mechanism 5, the contact frame 49 can drive the limit mechanism 5 to operate. A mounting plate 47 is fixedly connected to the left side of the sliding frame 41, and three rotating shafts 45 are evenly spaced and rotatably penetrated on the upper part of the mounting plate 47. A mounting plate 48 is installed on the left end of the rotating shaft 45. The three mounting plates 48 are respectively connected to the three sets of punches. The grinding roller 2 is fixedly connected. When the mounting plate 48 rotates, the mounting plate 48 can drive the grinding roller 2 to rotate. A transmission assembly 46 is connected between the right side of the middle rotating shaft 45 and the right sides of the front and rear rotating shafts 45 respectively. The transmission assembly 46 consists of two pulleys and a flat belt, wherein the two pulleys are fixedly mounted on the two rotating shafts 45 respectively, and the flat belt is wound between the two pulleys. A driving motor 43 is installed on the right side of the middle bottom of the sliding frame 41, and the output shaft of the driving motor 43 and the right side of the middle rotating shaft 45 are connected with a gear 44 through a key, and the two gears 44 are meshed.

[0035] The limiting mechanism 5 includes a limiting frame 52, a contact rod 53, a guide rod 54 and a first spring 55, see Figure 1 , Figure 5 and Figure 6As shown, guide rods 54 are symmetrically slidably connected on both sides of the front and rear of the top of the support frame 1, and a limit frame 52 is installed between the tops of the four guide rods 54 by welding. When the limit frame 52 moves downward, the limit frame 52 can press and fix the exhaust pipe. Contact rods 53 are fixed to the right parts of the front and rear sides of the outer top of the limit frame 52. The contact frame 49 moves to the left and contacts the contact rods 53. Four first springs 55 are connected between the inner top of the limit frame 52 and the outer top of the support frame 1, and the first springs 55 are sleeved on the guide rods 54.

[0036] First, the operator places the three exhaust pipes on the mounting frame 3. Since the positioning blocks are fixed to the right parts of the three inner sides of the upper part of the mounting frame 3, the exhaust pipes can be accurately placed in the specified position. Then the driving mechanism 4 is started. The driving mechanism 4 drives the grinding roller 2 to rotate, and then the driving mechanism 4 is pulled to move to the left. The driving mechanism 4 moves to the left and drives the grinding roller 2 to move to the left. When the driving mechanism 4 moves to the left and contacts with the limiting mechanism 5, the driving mechanism 4 drives the limiting mechanism 5 to move downward. The limiting mechanism 5 moves downward and contacts with the exhaust pipe. The limiting mechanism 5 cooperates with the mounting frame 3 to press and fix the exhaust pipe. At the same time, the grinding roller 2 moves to the left and contacts with the inner wall of the exhaust pipe. The grinding roller 2 rotates to remove the burrs on the inner wall of the exhaust pipe. When the drive mechanism 4 moves to the left to the maximum stroke, it means that the burrs on the inner wall of the exhaust pipe have been completely removed. Stop pulling the drive mechanism 4 to move to the left, and the drive mechanism 4 stops driving the grinding roller 2 to move to the left. Pull the drive mechanism 4 to move right and reset. The drive mechanism 4 moves right and resets to drive the grinding roller 2 to move right and reset. The grinding roller 2 resets and disengages from the inner wall of the exhaust pipe. At the same time, the drive mechanism 4 moves right and resets to disengage from the limit mechanism 5. The limit mechanism 5 moves upward and resets and disengages from the exhaust pipe. The operator can take out the exhaust pipe with burrs removed from the mounting frame 3, and then put in three exhaust pipes. Repeat this process to continuously remove the burrs on the inner wall of the exhaust pipe. When the burrs on all exhaust pipes have been removed, turn off the drive mechanism 4, and the drive mechanism 4 stops driving the grinding roller 2 to rotate.

[0037] After the exhaust pipe is placed, the drive motor 43 is started, and the rotation of the drive motor 43 drives the lower gear 44 to rotate, the rotation of the lower gear 44 drives the upper gear 44 to rotate, the rotation of the upper gear 44 drives the middle shaft 45 to rotate, the rotation of the middle shaft 45 drives the transmission assembly 46 to rotate, the rotation of the transmission assembly 46 drives the remaining two shafts 45 to rotate, the rotation of the three shafts 45 drives the three mounting plates 48 to rotate, the rotation of the mounting plates 48 drives the grinding roller 2 to rotate, and then pulls the sliding frame 41 to move left, and the sliding frame 41 moves left with The movable mounting plate 47 and the contact frame 49 move to the left. When the contact frame 49 moves to the left and contacts the limiting mechanism 5, the contact frame 49 drives the limiting mechanism 5 to move downward to press and fix the exhaust pipe. At the same time, the mounting plate 47 moves to the left and drives the rotating shaft 45 to move to the left. The rotating shaft 45 moves to the left and drives the mounting plate 48 to move to the left. The mounting plate 48 moves to the left and drives the grinding roller 2 to move to the left. The grinding roller 2 moves to the left and contacts the inner wall of the exhaust pipe. The grinding roller 2 rotates to remove the burrs on the inner wall of the exhaust pipe. When the sliding frame 41 moves to the left to the maximum stroke, it stops. Push the sliding frame 41 to move to the left, the sliding frame 41 stops driving the mounting plate 47 and the contact frame 49 to move to the left, the mounting plate 47 stops driving the mounting plate 48 to move to the left through the rotating shaft 45, the mounting plate 48 stops driving the grinding roller 2 to move to the left, and the sliding frame 41 can be pulled to move to the right to reset, the sliding frame 41 moves to the right to drive the mounting plate 47 and the contact frame 49 to move to the right to reset, the contact frame 49 resets and disengages from the limit mechanism 5, the limit mechanism 5 moves upward to reset and disengages from the exhaust pipe, the mounting plate 47 moves to the right to reset through the rotating shaft 45 drives the mounting plate 48 to move rightward and reset, and the mounting plate 48 moves rightward and resets, which drives the grinding roller 2 to move rightward and resets, and the exhaust pipe can be removed. This is repeated, and the grinding roller 2 can be continuously driven to move leftward to remove the burrs on the inner wall of the exhaust pipe. When all the burrs on the inner wall of the exhaust pipe are removed, the drive motor 43 is turned off, and the drive motor 43 stops driving the lower gear 44 to rotate, and the lower gear 44 stops driving the upper gear 44 to rotate, and the rotating shaft 45 also stops driving the mounting plate 48 to rotate, and the mounting plate 48 stops driving the grinding roller 2 to rotate.

[0038] When the operator pulls the sliding frame 41 to move to the left, the contact frame 49 moves to the left and contacts the contact rod 53, and the contact frame 49 drives the contact rod 53 to move downward, and the contact rod 53 moves downward and drives the limit frame 52 to move downward, and the first spring 55 is compressed. When the limit frame 52 moves downward and contacts the exhaust pipe, the limit frame 52 cooperates with the mounting frame 3 to press and fix the exhaust pipe, and the grinding roller 2 moves to the left to remove the burrs on the inner wall of the exhaust pipe. When the burrs on the inner wall of the exhaust pipe are removed, the sliding frame 41 is pulled to move to the right to reset, and the sliding frame 41 resets and drives the contact frame 49 to move to the right to reset, and the contact frame 49 resets and disengages from the contact rod 53. Due to the action of the first spring 55, the limit frame 52 moves upward to reset and disengages from the exhaust pipe. In this way, the movement of the exhaust pipe can be avoided to affect the removal of burrs.

[0039] Example 2

[0040] On the basis of embodiment 1, a cleaning mechanism 6 is also included, and the cleaning mechanism 6 includes a fixed rod 61, a magnetic block 62, a fixed frame 63, a rotating shaft 64, a spiral spring 65, a limiting cylinder 66, a guide column 67, a second spring 68, a magnet 69 and a cleaning disk 610, see Figure 1 and Figure 7 As shown, three fixing frames 63 are installed at even intervals on the upper part of the left side surface of the support frame 1 by welding connection, and a rotating shaft 64 is rotatably connected between the upper parts of the three fixing frames 63, and a volute spring 65 is connected between the upper parts of the outer sides of the fixing frames 63 on the front and rear sides of the rotating shaft 64 respectively, and three limiting cylinders 66 are fixedly sleeved on the rotating shaft 64 at even intervals, and a guide column 67 is slidably connected between the middle parts of the left and right sides of the limiting cylinder 66, and a second spring 68 is wound between the left end of the guide column 67 and the outer left side surface of the limiting cylinder 66, and a magnet 69 is fixedly connected to the right end of the guide column 67, and a cleaning disk 610 is fixedly connected to the outer side of the magnet 69 along the circumferential direction. When the cleaning disk 610 moves to the right, the cleaning disk 610 can remove debris in the exhaust pipe, and a fixing rod 61 is installed in the middle part of the left side surface of the mounting plate 48 by welding connection, and a magnetic block 62 is fixedly connected to the left end of the fixing rod 61. When the magnetic block 62 contacts the magnet 69, the magnetic block 62 can drive the magnet 69 to move to the right.

[0041] The unloading mechanism 7 includes an L-shaped trigger rod 71, a hinge plate 72, a hinge rod 73, a short shaft 74, a slider 75, a guide column 76 and a third spring 77. Figure 1 , Figure 8 and Fig. 9As shown, there are four sliders 75 evenly spaced along the circumferential direction on the left side of the cleaning plate 610 in an embedded sliding connection. When the slider 75 moves to the left, the slider 75 can drive the exhaust pipe to move to the left. Four guide posts 76 are evenly spaced along the circumferential direction on the left side of the cleaning plate 610 by welding. The guide posts 76 correspond to the sliders 75. The guide posts 76 pass through the middle of the sliders 75. The guide posts 76 are used for guiding. A third spring 77 is connected between the inner end of the slider 75 and the inner side of the cleaning plate 610. The third spring 77 is sleeved on the guide posts 7 6, the left end of the slider 75 is rotatably connected with a short shaft 74, and a hinge rod 73 is fixedly mounted on the short shaft 74. A hinge plate 72 is slidably mounted on the right side of the guide column 67. The outer end of the hinge plate 72 is rotatably connected to the left end of the hinge rod 73. An L-shaped trigger rod 71 is installed on the upper right side of the limit cylinder 66 by welding. The right side of the L-shaped trigger rod 71 is slidably mounted on the guide column 67. The L-shaped trigger rod 71 contacts the hinge rod 73. When the hinge rod 73 moves to the left to reset, the L-shaped trigger rod 71 can drive the hinge rod 73 to swing inward.

[0042] When the operator pulls the sliding frame 41 to move to the left, the mounting plate 48 moves to the left and drives the fixing rod 61 to move to the left. The fixing rod 61 moves to the left and drives the magnetic block 62 to move to the left. When the magnetic block 62 moves to the left and contacts the magnet 69, the magnetic block 62 and the magnet 69 are attracted to each other by magnetic force. At this time, the grinding roller 2 removes the burrs on the inner wall of the exhaust pipe. The sliding frame 41 is pulled to move to the right and reset. The mounting plate 48 moves to the right and drives the fixing rod 61 to move to the right. The fixing rod 61 moves to the right and drives the magnetic block 62 to move to the right. The magnetic block 62 moves to the right and drives the magnet 69 to move to the right. The magnet 69 moves to the right and drives the cleaning plate 610 and the guide column 67 to move to the right. The second spring 68 is compressed. The cleaning plate 610 moves to the right and contacts the inner wall of the exhaust pipe, and the cleaning plate 610 also pushes the debris in the exhaust pipe to move to the right. When the cleaning plate 610 moves to the right and loses contact with the exhaust pipe, all the debris in the exhaust pipe falls out. At the same time, the guide post 67 moves to the right to the maximum stroke, and the guide post 67 stops moving to the right, so that the magnet 69 stops moving to the right, and the magnet 69 stops moving to the right, so that the cleaning plate 610 stops moving to the right. The magnetic block 62 continues to move to the right and resets and loses contact with the magnet 69. Due to the action of the second spring 68, the guide post 67 moves to the left and resets, driving the magnet 69 to move to the left and resets, and the magnet 69 moves to the left and resets, driving the cleaning plate 610 to move to the left and resets. In this way, the debris residue in the exhaust pipe can be prevented from affecting the collection.

[0043] Initially, the third spring 77 is in a compressed state. When the magnetic block 62 drives the magnet 69 to move rightward, the magnet 69 moves rightward and drives the guide column 67 and the cleaning disk 610 to move rightward. The cleaning disk 610 moves rightward and drives the slider 75 to move rightward. The slider 75 moves rightward and drives the short shaft 74 to move rightward. The short shaft 74 moves rightward and drives the hinged rod 73 to move rightward. The hinged rod 73 moves rightward and drives the hinged disk 72 to move rightward. The hinged rod 73 moves rightward and disengages from the L-shaped trigger rod 71. Due to the action of the third spring 77, the slider 75 moves outward a certain distance and drives the short shaft 74 to move outward. The short shaft 74 moves outward and drives the hinged rod 73 When the slider 75 moves to the right and loses contact with the exhaust pipe, the slider 75 is reset by the exhaust pipe, and the third spring 77 is compressed, and the slider 75 moves inwardly through the short shaft 74 to drive the hinge rod 73 to swing inwardly. The hinge rod 73 swings inwardly and drives the hinge plate 72 to move a certain distance to the left. When the slider 75 continues to move to the right and loses contact with the exhaust pipe, due to the action of the third spring 77, the slider 75 moves outward a certain distance, and the hinge plate 72 also moves to the right a certain distance. When the magnetic block 62 moves to the right and loses contact with the magnet 69, due to the action of the second spring 77, the slider 75 is reset by the exhaust pipe. Due to the action of spring 68, guide post 67 moves to the left and resets, driving magnet 69 to move to the left and reset. Magnet 69 moves to the left and resets, driving cleaning plate 610 to move to the left. Cleaning plate 610 moves to the left and drives slider 75 to move to the left. Slider 75 moves to the left and drives exhaust pipe to move to the left. At the same time, slider 75 also drives hinged rod 73 to move to the left and reset through short shaft 74. Hinge rod 73 moves to the left and resets and contacts L-shaped trigger rod 71. L-shaped trigger rod 71 makes hinged rod 73 swing inward. Hinge rod 73 swings inward and drives slider 75 to move inward and reset through short shaft 74. Slider 75 moves inward and loses contact with exhaust pipe. At this time, exhaust pipe 71 is turned off. The exhaust pipe moves to the left and is out of contact with the mounting frame 3. Due to the weight of the exhaust pipe, the exhaust pipe drives the guide post 67 to rotate forward, the guide post 67 rotates forward and drives the limit cylinder 66 to rotate forward, the limit cylinder 66 rotates forward and drives the rotating shaft 64 to rotate forward, the volute spring 65 is compressed, and when the guide post 67 rotates forward and is in an inclined state, the exhaust pipe moves downward and is out of contact with the guide post 67 and the cleaning disk 610, and the operator can collect the fallen exhaust pipe. Due to the action of the volute spring 65, the rotating shaft 64 reverses and drives the limit cylinder 66 to reverse and reset, and the limit cylinder 66 reverses and resets and drives the guide post 67 to reverse and reset, and the guide post 67 reverses and resets and drives the cleaning disk 610 to swing upward and reset through the magnet 69. In this way, the operator does not need to remove the exhaust pipe from the mounting frame 3 by hand, which is convenient and quick.

[0044] Example 3

[0045] On the basis of the embodiment 1 and the embodiment 2, a collecting mechanism 8 is also included. The collecting mechanism 8 includes a collecting frame 81, a mounting rod 82 and a fixed threaded disk 83. Figure 1 and Fig.10 As shown, two mounting rods 82 are symmetrically slidably connected front to back on the left side of the bottom of the support frame 1. The top of the mounting rod 82 is connected to a fixed threaded disk 83 by a threaded rotation. A collection frame 81 is installed between the bottom ends of the four mounting rods 82 by welding. When the debris is pushed out, the collection frame 81 can collect the debris.

[0046] The material guiding mechanism 9 includes a fixing column 91 and a guide plate 92. Figure 1 and Fig.11 As shown, a fixing column 91 is symmetrically fixed and connected to the left side of the bottom of the fixing frame 63, and a guide plate 92 is installed between the bottom ends of the six fixing columns 91 by welding. When the exhaust pipe falls, the guide plate 92 can buffer and guide the exhaust pipe.

[0047] When the cleaning plate 610 moves to the right to push out the debris in the exhaust pipe, the debris falls into the collection frame 81 and is collected. When the collection frame 81 is filled with an appropriate amount of debris, the fixed threaded plate 83 is twisted in reverse to move upward through the thread to disengage from the mounting rod 82, and then the collection frame 81 is pulled downward to drive the mounting rod 82 to move downward and disengage from the support frame 1, so that all the debris in the collection frame 81 can be poured out for processing. After all the debris is poured out, the collection frame 81 is moved so that the mounting rod 82 is placed back on the support frame 1, and then the fixed threaded plate 83 is moved to contact the top of the mounting rod 82, and the fixed threaded plate 83 is twisted to move forward and downward to fix the mounting rod 82, thereby fixing the collection frame 81. In this way, debris can be prevented from falling to the surroundings and affecting the environment.

[0048] When the exhaust pipe after deburring falls from the guide post 67 and the cleaning plate 610, the exhaust pipe falls onto the guide plate 92, and the guide plate 92 cushions the exhaust pipe. The buffered exhaust pipe rolls to the ground, and the operator can collect the rolled exhaust pipe. In this way, the exhaust pipe can be prevented from violently falling to the ground and causing wear.
