Description

Technical Field

[0001] This utility model relates to the technical field of exhaust pipe polishing equipment, specifically an exhaust pipe polishing device. Background Technology

[0002] With the development of society and economy and the continuous progress of modern technology, the automotive industry has also made great strides. Among them, civilian cars have gradually entered the homes of millions of residents, becoming one of the commonly used means of transportation. The exhaust pipe is installed between the exhaust manifold and the muffler of the car engine, enabling the entire exhaust system to work properly, thereby playing a role in vibration reduction, noise reduction, and extending the life of the exhaust muffler system. In addition, the main material of the exhaust pipe is stainless steel. During the processing of the exhaust pipe, it is necessary to grind it to achieve a smooth surface and facilitate its installation. Therefore, the equipment technology for exhaust pipe grinding is very important.

[0003] According to Chinese patent CN210588540U, a grinding device for the production of exhaust pipes for new energy vehicles is proposed. The device includes a turntable, a sliding groove, a fixed rod, a threaded cylinder, and a grinding part. The grinding part can be fitted onto the neck of the exhaust pipe. Then, the motor drives the turntable to rotate, which in turn drives the grinding part on the fixed rod to rotate, thereby deburring the neck of the exhaust pipe.

[0004] However, there are still some shortcomings in this patent. The device can grind the edge of the exhaust pipe by rotating the grinding part, but in the actual production process, some defects are easily generated on the outer wall of the exhaust pipe. The device cannot grind the outer wall of the exhaust pipe, which affects the use effect of the exhaust pipe and reduces the grinding efficiency of the device. Therefore, we propose an exhaust pipe grinding device. Utility Model Content

The side wall of the rectangular grinding block is slidably connected to the right end face of the exhaust pipe body. The rectangular grinding block has a support block fixedly connected to its side wall. The inner wall of the support block is slidably connected to the bottom outer wall of the exhaust pipe body. During the grinding process of the exhaust pipe body, the operator starts the dual-axis motor to make the first output shaft rotate. During the rotation of the first output shaft, the gear will rotate, and the gear will mesh with the rack, thereby moving the horizontal plate. Then, by starting the second electric push rod, the lifting plate will move upward, so that the side wall of the rectangular grinding block is in contact with the end face of the exhaust pipe body, and the inner wall of the support block is in contact with the outer wall of the exhaust pipe body. Thus, the end face of the exhaust pipe body can be ground by the rectangular grinding block.

[0008] Preferably, the top of the mounting plate is further provided with a fixing assembly, which includes a side plate fixedly connected to the top left side of the mounting plate. A second drive motor is fixedly connected to the top side wall of the side plate. A second output shaft is fixedly connected to the output end of the second drive motor.

The inner wall of the clamping block is flush with the exhaust pipe body. The outer wall is slidably connected. By setting a fixing component, the exhaust pipe body needs to be clamped and fixed before grinding. At this time, the operator puts one end of the exhaust pipe body against the side wall of the turntable, and then rotates the adjusting block to make the screw rotate. After the screw rotates, it will cause the clamping block to move, so that the clamping block can clamp and fix the exhaust pipe body. Then, the operator starts the second drive motor to make the second output shaft rotate, which will make the turntable rotate and take the exhaust pipe body with it, so as to facilitate the adjustment of the grinding position of the exhaust pipe body during the grinding process.

Then the first drive motor is turned on, which causes the lead screw to rotate. During the rotation of the lead screw, the sleeve block will move along the outer wall of the lead screw, thereby causing the arc-shaped grinding block to move, so as to achieve uniform grinding of the surface of the exhaust pipe body. During the grinding of the exhaust pipe body, the operator starts the dual-axis motor, which causes the first output shaft to rotate. During the rotation of the first output shaft, the gear will rotate, and the gear will mesh with the rack, thereby causing the horizontal plate to move. Then the second electric push rod is started, which causes the lifting plate to move upward, causing the side wall of the rectangular grinding block to be in contact with the end face of the exhaust pipe body, and causing the inner wall of the bearing block to be in contact with the outer wall of the exhaust pipe body, so that the end face of the exhaust pipe body can be ground by the rectangular grinding block.

[0016] (2) The exhaust pipe grinding device, by setting a fixing component, needs to clamp and fix the exhaust pipe body before grinding. At this time, the operator puts one end of the exhaust pipe body against the side wall of the turntable, and then rotates the adjusting block to make the screw rotate. After the screw rotates, it will cause the clamping block to move, so that the clamping block can clamp and fix the exhaust pipe body. Then, the operator starts the second drive motor to make the second output shaft rotate, thereby causing the turntable to rotate and the exhaust pipe body to rotate, so as to facilitate the adjustment of the grinding position of the exhaust pipe body during the grinding process.

[0024] A preferred embodiment of the exhaust pipe polishing device provided by this utility model is, for example... Figures 1 to 5 As shown: An exhaust pipe polishing device includes a mounting plate 1 and a polishing assembly 31 disposed on the top of the mounting plate 1. The polishing assembly 31 includes a support rod 311 fixedly connected to the top of the mounting plate 1. A rectangular frame 312 is fixedly connected to the other end of the support rod 311. A first drive motor 313 is fixedly connected to the left outer wall of the rectangular frame 312. A lead screw 314 is fixedly connected to the output end of the first drive motor 313. The lead screw 314 movably passes through the outside of the rectangular frame 312 and extends into the inside of the lead screw 314. The other end of the lead screw 314 is rotatably connected to the inner wall of the rectangular frame 312. A sleeve block 315 is threadedly connected to the outer wall of the lead screw 314. A first electric push rod 316 is fixedly connected to the bottom of the sleeve block 315. An arc-shaped grinding block 317 is fixedly connected to the output end of the push rod 316. The bottom of the arc-shaped grinding block 317 is slidably connected to the exhaust pipe body 318. By setting the grinding assembly 31, when the exhaust pipe body 318 needs to be ground, the operator starts the first electric push rod 316, which pushes the arc-shaped grinding block 317 downward, so that the inner wall of the arc-shaped grinding block 317 fits against the outer wall of the exhaust pipe body 318. Then, the first drive motor 313 is turned on, which causes the lead screw 314 to rotate. During the rotation of the lead screw 314, the sleeve block 315 moves along the outer wall of the lead screw 314, thereby causing the arc-shaped grinding block 317 to move, so as to achieve uniform grinding of the surface of the exhaust pipe body 318.

[0025] The grinding assembly 31 also includes a support frame 319 fixedly connected to the top of the mounting plate 1. A dual-axis motor 3110 is fixedly connected to the inner top wall of the support frame 319. A first output shaft 3111 is fixedly connected to the output end of the dual-axis motor 3110. A gear 3112 is fixedly connected to the outer wall of the other end of the first output shaft 3111. A rack 3113 meshes with the bottom of the gear 3112. The bottom of the rack 3113 is slidably connected to the top of the mounting plate 1. A horizontal plate 3114 is fixedly connected to the side wall of the rack 3113. A second electric push rod 3115 is fixedly connected to the top of the horizontal plate 3114. A lifting plate 3116 is fixedly connected to the output end of the second electric push rod 3115.

The side wall of the rectangular grinding block 3117 is slidably connected to the right end face of the exhaust pipe body 318. A bearing block 3118 is fixedly connected to the side wall of 7. The inner wall of the bearing block 3118 is slidably connected to the bottom outer wall of the exhaust pipe body 318. During the grinding process of the exhaust pipe body 318, the operator starts the dual-axis motor 3110 to make the first output shaft 3111 rotate. During the rotation of the first output shaft 3111, the gear 3112 will rotate, and the gear 3112 will mesh with the rack 3113, thereby moving the horizontal plate 3114. Then, by starting the second electric push rod 3115, the lifting plate 3116 will move upward, causing the side wall of the rectangular grinding block 3117 to fit with the end face of the exhaust pipe body 318, and the inner wall of the bearing block 3118 to fit with the outer wall of the exhaust pipe body 318. Thus, the end face of the exhaust pipe body 318 can be ground by the rectangular grinding block 3117.

[0026] A preferred embodiment of the exhaust pipe polishing device provided by this utility model is, for example... Figures 1 to 5As shown: A fixing component 32 is also provided on the top of the mounting plate 1. The fixing component 32 includes a side plate 321 fixedly connected to the top left side of the mounting plate 1. A second drive motor 322 is fixedly connected to the top side wall of the side plate 321. A second output shaft 323 is fixedly connected to the output end of the second drive motor 322. The second output shaft 323 movably passes through the interior of the side plate 321. A turntable 324 is fixedly connected to the other end of the second output shaft 323. A fixing block 325 is fixedly connected to the side wall of the turntable 324. A screw 326 is threadedly connected to the inner wall of the fixing block 325. An adjusting block 327 is fixedly connected to the top outer wall of the screw 326. A clamping block 328 is rotatably connected to the other end of the screw 326. The inner wall of the clamping block 328 is flush with the outer wall of the exhaust pipe body 318. The sliding connection, through the setting of the fixing component 32, requires clamping and fixing the exhaust pipe body 318 before grinding. At this time, the operator puts one end of the exhaust pipe body 318 against the side wall of the turntable 324, and then rotates the adjusting block 327 to cause the screw 326 to rotate. After the screw 326 rotates, it will cause the clamping block 328 to move, so that the clamping block 328 can clamp and fix the exhaust pipe body 318. Then, the operator starts the second drive motor 322 to cause the second output shaft 323 to rotate, thereby causing the turntable 324 to rotate, and taking the exhaust pipe body 318 with it, so as to facilitate the adjustment of the grinding position of the exhaust pipe body 318 during the grinding process.

[0027] Furthermore, the bottom of the mounting plate 1 is fixedly connected to the support pads 2. There are four support pads 2, which are fixedly connected at equal intervals at the four corners of the bottom of the mounting plate 1. By setting four support pads 2, it is easy to achieve a stable support for the mounting plate 1.

[0028] Furthermore, the top outer wall of the socket block 315 is slidably connected to the inner wall of the rectangular frame 312, and the top inner wall of the socket block 315 is threadedly connected to the outer wall of the lead screw 314. By setting the rectangular frame 312 and the socket block 315, it is easy to limit the socket block 315 so that the socket block 315 can move on the outer wall of the lead screw 314.

[0029] Furthermore, there are four support rods 311, which are fixedly connected at equal intervals to the bottom of the four corners of the rectangular frame 312. By setting four support rods 311, it is easy to support the rectangular frame 312.

[0030] Furthermore, the inner wall of gear 3112 is fixedly connected to the outer wall of one end of the first output shaft 3111, and the bottom of gear 3112 is slidably connected to the top of rack 3113.

[0031] In addition, there are two clamping blocks 328. The two clamping blocks 328 are of equal size and are symmetrically distributed along the center plane of the exhaust pipe body 318. By setting two clamping blocks 328, it is easy to clamp and fix the exhaust pipe body 318.

[0032] Working principle: Before grinding the exhaust pipe body 318, it is necessary to clamp and fix the exhaust pipe body 318. At this time, the operator puts one end of the exhaust pipe body 318 against the side wall of the turntable 324, and then rotates the adjusting block 327 to make the screw 326 rotate. After the screw 326 rotates, it will cause the clamping block 328 to move, so that the clamping block 328 can clamp and fix the exhaust pipe body 318. Then, the operator starts the second drive motor 322 to make the second output shaft 323 rotate, which will make the turntable 324 rotate, and take the exhaust pipe body 318 with it to rotate, so as to make it easier to adjust the grinding position of the exhaust pipe body 318 during the grinding process.

[0033] During the grinding process of the exhaust pipe body 318, the operator starts the first electric push rod 316, which pushes the arc-shaped grinding block 317 downward, so that the inner wall of the arc-shaped grinding block 317 fits against the outer wall of the exhaust pipe body 318. Then, the first drive motor 313 is turned on, which causes the lead screw 314 to rotate. During the rotation of the lead screw 314, the sleeve block 315 moves along the outer wall of the lead screw 314, thereby causing the arc-shaped grinding block 317 to move, so as to achieve uniform grinding of the surface of the exhaust pipe body 318.

[0034] During the grinding process of the exhaust pipe body 318, the operator starts the dual-axis motor 3110, causing the first output shaft 3111 to rotate. During the rotation of the first output shaft 3111, the gear 3112 will rotate, causing the gear 3112 to mesh with the rack 3113, thereby moving the horizontal plate 3114. Then, by starting the second electric push rod 3115, the lifting plate 3116 is moved upward, causing the side wall of the rectangular grinding block 3117 to fit with the end face of the exhaust pipe body 318, and causing the inner wall of the bearing block 3118 to fit with the outer wall of the exhaust pipe body 318. Thus, the end face of the exhaust pipe body 318 can be ground by the rectangular grinding block 3117.
