Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices and relates to a grinding device for a muffler pipe section. Background Art

[0002] The silencer is an important component of the silencer. The silencer refers to a noise reduction device that can be used to reduce the noise in the airflow pipe with noise transmission, such as pipes and elbows with sound-absorbing lining or pipes with sudden changes in cross-sectional area and other discontinuous acoustic impedance, so as to attenuate or reflect the noise in the pipe. The former is called a resistive silencer, the latter is called a reactive silencer, and there is also an impedance composite silencer. There are many types of silencers, but in terms of their silencer mechanism, they can be divided into six main types, namely, resistive silencers, reactive silencers, impedance composite silencers, micro-perforated plate silencers, small hole silencers and active silencers.

[0003] The existing silencer pipe needs to be polished during processing to remove the burrs on the outside of the silencer pipe. Since the silencer pipe is made of metal, the contact between the abrasive belt and the metal during polishing will generate a large amount of sparks and dust downwards. The high-temperature flying metal sparks can easily injure the user, and the flying sparks can also easily cause fire accidents. Utility Model Content

DETAILED DESCRIPTION

[0026] The utility model is further described below in conjunction with the accompanying drawings.

A vertical rod 52 is installed, and inclined blocks 53 are installed at both ends of the vertical rod 52. A grinding wheel 54 is installed on one side of the inclined block 53. A rectangular hole 6 is opened at the bottom of the vertical rod 52, and a connecting column 61 is installed in the rectangular hole 6. At the same time, a protective tube 2 is installed at the lower inclined block 53. The protective tube 2 is divided into an upper pipe 21 and a lower pipe 22. A hollow part 7 is opened in the protective tube 2, and a fixed block 71 is installed on one side of the hollow part 7. A through slot 72 is opened in the fixed block 71, and a tension spring 73 is installed in the through slot 72. Side plates 8 are symmetrically provided on the outer wall of the lower pipe 22, and a cylinder 81 is installed between adjacent side plates 8.

[0028] In this embodiment, the grinding device 1 is an existing equipment, and the grinding component 5 is located on one side of the grinding device 1, where a slide rail is opened and a screw is installed inside the slide rail. The grinding component 5 and the slide rail are slidably connected, and the screw blade passes through the grinding component 5. The grinding component 5 can move along the slide rail through the screw. The grinding component 5 itself is symmetrically provided with slide rails, and the component installed with the cross bar 51 can move along the slide rail here. Therefore, the grinding component 5 can move in the XY axis direction for grinding work. At the same time, a grinding belt can be sleeved between the grinding wheels 54, and a motor 42 is provided in the grinding component 5 to drive the grinding belt to rotate. The above is an introduction to the components of the grinding component 5. The specific movement mode and grinding principle are existing technologies, so they are not repeated.

[0029] Combination Figure 1 , Figure 2 As shown, the support plates 3 are symmetrically arranged, and the support plates 3 are located at the bottom of the columns 4 , and the bolts 41 are inserted into the grooves 31 .

[0030] Furthermore, the bolts 41 are inserted into the groove 31 , so the column 4 can not only be fixed to the groove 31 by the bolts 41 , but also the position of the column 4 in the groove 31 can be adjusted by loosening or tightening the bolts 41 .

[0031] Combination Figure 1 , Figure 2As shown, the groove 31 is connected to the column 4 by bolts 41 and the groove 31, and the rotating shaft of the motor 42 passes through the column 4, and the rotating shaft is rotatably connected to the column 4. The extended end of the electric telescopic rod 44 passes through the column 4 and is installed with a cylinder 43, and the extended end is rotatably connected to the column 4. At the same time, a limit ring is installed on the cylinder 43, and the cylinder 43 is rotatably connected to the extended end of the electric telescopic rod 44.

[0032] Furthermore, the cylinders 43 on both sides are inserted into the two ends of the silencer pipe to be polished, the electric telescopic rod 44 is pushed forward, the limiting ring on the cylinder 43 is pressed against the silencer pipe to achieve limiting, and then the motor 42 rotates to drive the cylinder 43 to rotate the middle silencer pipe, so that the sanding belt can evenly polish the silencer pipe.

[0033] Combination Figure 1 , Figure 2 As shown, the grinding wheel 54 and the inclined block 53 are rotatably connected, and a through hole penetrating the outer wall is opened in the connecting column 61.

[0034] Furthermore, the grinding component 5 is provided with a motor 42, and a grinding belt can be sleeved on the outside of the grinding wheel 54. The motor 42 drives the grinding belt to drive the grinding wheel 54. The principle here is similar to the operating principle of a belt and a pulley. The through hole in the connecting column 61 is used to connect the tension spring 73.

[0035] Combination Figure 3 , Figure 4 , Figure 5 As shown, an opening is provided on one side of the hollow space 7 , and the bottom of the vertical rod 52 is inserted into the hollow space 7 . The width of the hollow space 7 is greater than that of the grinding wheel 54 .

[0036] Furthermore, the opening of the hollow part 7 is used to provide space for the grinding wheel 54 at the bottom of the vertical rod 52 to move, so as to avoid hindering the operation of the grinding belt and the rotation of the protection tube 2 around the inclined block 53.

[0037] Combination Figure 3 , Figure 4 , Figure 5 As shown, a pin is installed on the inner wall of one side of the hollow space 7, and the protection tube 2 is rotatably connected to the inclined block 53 on the lower side through the pin.

[0038] Furthermore, the protection tube 2 is rotatably connected via a pin and an inclined block 53 , and this connection is coaxial with the grinding wheel 54 . The blank area between the fixed block 71 and the upper pipe 21 is much larger than the grinding wheel 54 , and the grinding wheel 54 is located in this area.

[0039] Combination Figure 3 , Figure 4 , Figure 5As shown, the fixing block 71 and the vertical rod 52 are located on the same side, the lower side of the through slot 72 passes through the outer wall of the fixing block 71 , and the other end of the tension spring 73 is connected to the through hole in the connecting column 61 .

[0040] Furthermore, when the cylinder 81 abuts against the support plate 3 and the protective tube 2 rotates at the inclined block 53 through the pin, the tension spring 73 is stretched. When the cylinder 81 and the support plate 3 are separated, the tension spring 73 uses elastic force to pull the protective tube 2 back to the initial position.

[0041] Combination Figure 3 , Figure 4 , Figure 5 As shown, the lower pipe 22 is obliquely installed at the bottom of the upper pipe 21, and the upper pipe 21 and the lower pipe 22 are connected to each other.

[0042] Furthermore, the obliquely installed lower pipe 22 increases the movement distance of the sparks and prolongs the cooling time, allowing the sparks to fall toward the ground.

[0043] Combination Figure 3 , Figure 4 , Figure 5 As shown, two groups of side plates 8 are arranged at intervals on the lower pipe 22, the cylinder 81 and the side plates 8 are rotatably connected, and the height of the support plate 3 in the horizontal direction is located at the middle line of the cylinder 81.

[0044] Furthermore, the height of the support plate 3 is equal to the middle line of the cylinder 81. The support plate 3 presses against the cylinder 81 to allow the protective tube 2 to rotate. The cylinder 81 rotates along the support plate 3 to effectively reduce friction and reduce equipment loss. A rubber pad can be installed on the outside of the cylinder 81 to reduce the force.

[0045] The working principle of the utility model is:

[0046] Insert one end of the muffler to be polished on the cylinder 43 at one end of the motor 42, and at the same time, extend the electric telescopic rod 44 forward to insert the cylinder 43 here into the other end of the muffler. When the limit rings on the cylinder 43 are against the two ends of the muffler, the motor 42 rotates to drive the cylinder 43 to rotate toward the middle muffler pipe.

[0047] The motor 42 in the grinding component 5 drives the sanding belt to rotate, and the grinding component 5 moves toward the direction of the muffler. When the cylinder 81 at the bottom of the lower pipe 22 contacts the support plate 3, the support plate 3 presses against the cylinder 81, so that the protective pipe 2 rotates based on the internal pin shaft. At this time, the distance between the upper pipe 21 and the vertical rod 52 becomes larger, and the tension spring 73 stretches and lengthens to produce a reverse elastic force. The grinding component 5 will move horizontally during grinding to facilitate the sanding belt to evenly grind every part of the muffler. The bottom cylinder 81 also rotates while moving along the support plate 3, effectively reducing friction and reducing equipment loss.

[0048] The opening and closing angle of the protection tube 2 relative to the vertical rod 52 becomes larger. When the grinding component 5 moves, the cylinder 81 rolls along the support plate 3. The protection tube 2 is always located directly below the sanding belt. The metal sparks move downward along the sanding belt and along the protection tube 2 to the bottom, preventing the metal sparks from injuring the user and preventing the flying sparks from causing fire accidents.

[0049] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways without departing from the spirit of the present invention.

[0050] Although this article uses more terms such as 1. grinding device; 2. protective tube; 21. upper pipe; 22. lower pipe; 3. support plate; 31. groove; 4. column; 41. bolt; 42. motor; 43. cylinder; 44. electric telescopic rod; 5. grinding component; 51. cross bar; 52. vertical bar; 53. inclined block; 54. grinding wheel; 6. rectangular hole; 61. connecting column; 7. hollow; 71. fixed block; 72. through slot; 73. tension spring; 8. side plate; 81. cylinder, it does not exclude the possibility of using other terms. The use of these terms is only for more convenient description and explanation of the essence of the utility model. It is contrary to the spirit of the utility model to interpret them as any additional restrictions.
