Description

Technical Field

[0001] This utility model relates to a burr removal device, specifically a burr removal device for a speed reducer housing, belonging to the technical field of casting burr removal device. Background Technology

[0002] As a key component of the transmission system, the machining accuracy of the motorcycle gearbox housing directly affects the gearbox's operational stability, transmission efficiency, and service life. The motorcycle gearbox housing is primarily made of cast aluminum alloy, and the cast blank inevitably produces numerous burrs. These burrs not only make housing assembly difficult but may also scratch seals during assembly, causing malfunctions such as oil leaks.

[0003] Due to the complex shape of the reducer housing, with multiple irregular curved surfaces, holes, and corners, traditional methods such as manual filing and sanding are difficult to balance efficiency and precision, and are also labor-intensive and inconsistent. Currently, the industry mostly uses magnetic polishing machines to remove surface burrs. This equipment adds water and polishing agent in a specific ratio to a polishing tank to form a polishing fluid, inserts magnetic needles, and then places the reducer housing in the polishing tank. The internal disk movement drives the magnetic needles to randomly collide and rub against the surface of the housing, thus achieving efficient burr removal. Typically, the polishing agent added once can meet the needs of multiple polishing operations, making it economical.

[0004] However, after each polishing, a large amount of aluminum alloy debris and polishing agent wear particles remain in the polishing solution. These debris accumulates with each polishing cycle, which reduces the effective contact between the magnetic needle and the surface of the housing, weakens the polishing force, and results in incomplete burr removal. Utility Model Content

[0005] The purpose of this invention is to provide a burr removal device for the housing of a speed reducer in order to solve the above-mentioned problems. After one polishing is completed, the device can automatically clean the polishing debris in the polishing fluid, thereby avoiding the debris generated during the polishing process from having a negative impact on subsequent polishing and effectively ensuring the polishing effect.

[0006] This utility model achieves the above-mentioned objective through the following technical solution: a deburring device for a reducer housing, comprising a magnetic polishing machine body, wherein the magnetic polishing machine body is provided with a cleaning structure, the cleaning structure comprising a support plate and a connecting cylinder, a support plate being fixedly connected to one side of the magnetic polishing machine body, a connecting cylinder being fixedly connected to the support plate, a short pipe being fixedly connected to the connecting cylinder, a sleeve being fixedly connected to the short pipe, a rotating pipe being rotatably connected to the sleeve, and a flexible tube being fixedly connected to one end of the rotating pipe, the magnetic...

Next, the filter cover can be removed from the inside of the connecting cylinder, making it easy to clean the debris collected inside. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, a burr removal device for a reducer housing includes a magnetic polishing machine body 1. The magnetic polishing machine body 1 has a burr removal structure 2, which includes a support plate 201 and a connecting cylinder 202. The support plate 201 is fixedly connected to one side of the magnetic polishing machine body 1. The connecting cylinder 202 is fixedly connected to the support plate 201. A short pipe 203 is fixedly connected to the connecting cylinder 202. One of the sleeves 204 is fixedly connected to the short pipe 203. A rotating pipe 205 is rotatably connected to the sleeve 204. A flexible hose 206 is fixedly connected to one end of the rotating pipe 205. A liquid pump 208 is installed on the magnetic polishing machine body 1. The liquid pump 208 and the connecting cylinder 202 are connected by a long pipe 207. Another sleeve 204 is fixedly connected to the liquid pump 208. A retaining sleeve 210 is engaged on the connecting cylinder 202. A support ring 211 is fixedly connected inside the connecting cylinder 202. An outer frame 212 is engaged on the support ring 211. A filter cover 213 is fixedly connected to the bottom side of the outer frame 212. A cover plate 209 is fixedly connected to the top of the retaining sleeve 210. The cover plate 209 abuts against the connecting cylinder 202. The bottom end of the retaining sleeve 210 abuts against the outer frame 212. A fixing structure 3 is provided on the connecting cylinder 202. A polishing groove 5 is placed on the top of the magnetic polishing machine body 1.

[0023] As a technical optimization of this utility model, a pull rod 214 is fixedly connected to the outer frame 212. The filter cover 213 can be easily removed from the inside of the connecting cylinder 202 by holding the pull rod 214. The pull rod 214 has a circular cross-section.

[0024] As a technical optimization of this utility model, the filter cover 213 has a U-shaped cross-section, so the filtered debris can be collected through the filter cover 213. The rotating tube 205 has an L-shaped cross-section, so when the rotating tube 205 rotates ninety degrees, the flexible tube 206 can move from the inside of the polishing tank 5 to the outside of the polishing tank 5.

[0025] As a technical optimization of this utility model, the fixing structure 3 includes a connecting seat 301 and a rotating shaft 302. The connecting seat 301 is fixedly connected to one side of the connecting cylinder 202. The rotating shaft 302 is rotatably connected to the connecting seat 301. A connecting rod 303 is fixedly connected to the rotating shaft 302. A stop block 305 is threadedly connected to the connecting rod 303. The bottom end of the stop block 305 abuts against the cover plate 209, thus achieving the fixing of the cover plate 2.

[0026] As a technical optimization of this utility model, the cross-section of the abutment 305 is T-shaped, which increases the contact area between the abutment 305 and the cover plate 209. The top side of the cover plate 209 is fixedly connected to a limiting sleeve 306, which engages with the bottom end of the abutment 305. Therefore, the limiting sleeve 306 can limit the abutment 305, thereby preventing it from rotating during the tightening process.

[0027] As a technical optimization of this utility model, a rotating rod 304 is fixedly connected to the abutment block 305. The rotating rod 304 passes through the abutment block 305 and is perpendicular to the abutment block 305, so the abutment block 305 can be easily rotated by holding the rotating rod 304.

[0028] As a technical optimization of this utility model, the sleeve 204 is provided with a limiting structure 4, the limiting structure 4 includes a connecting block 401 and a connecting shaft 402, the connecting block 401 is fixedly connected to the rotating tube 205, the connecting shaft 402 is rotatably connected to the connecting block 401, the locking block 403 is fixedly connected to the connecting shaft 402, the connecting sleeve 204 is fixedly connected to the sleeve 204, the connecting sleeve 405 is provided with four locking slots 406, the locking block 403 engages with one of the locking slots 406, thus fixing the rotating tube 205.

[0029] As a technical optimization of this utility model, the four slots 406 are arranged in a circumferential array about the middle of the connecting sleeve 405. Therefore, the position of the hose 206 can be changed by engaging the block 403 with different slots 406. The cross-section of one end of the slot 406 is trapezoidal, so it can play a role in motion guidance when the block 403 engages with the slot 406.

[0030] As a technical optimization of this utility model, a torsion spring 404 is fixedly connected between the connecting shaft 402 and the connecting block 401. Therefore, under the action of the torsion spring 404, the locking block 403 can always be engaged with the locking groove 406. The overall cross-section of the connecting block 401 is a U-shaped structure.

[0031] In use, after one polishing cycle, the liquid pump 208 can be activated. Because the magnetic needle is magnetic, it will not flow with the liquid under the influence of the disk. Since the polishing liquid and the resulting debris are not magnetic, the polishing liquid and debris inside the polishing tank 5 will enter the rotating tube 205 from one of the flexible hoses 206, then from the rotating tube 205 into one of the sleeves 204, then from the sleeve 204 into the short tube 203, then into the connecting cylinder 202, and finally through the abutment 21. The liquid enters the filter hood 213. As the liquid flows through the filter hood 213, debris and impurities are filtered out. The filtered liquid then flows from the long pipe 207 to the pump 208, then into another sleeve 204, and finally back into the polishing tank 5 through another hose 206. This continuous circulation of the polishing liquid effectively removes debris, preventing it from negatively impacting subsequent polishing and ensuring the polishing effect. Furthermore, once the debris is removed, it can move away from the connecting sleeve 40. 5. Rotate the locking block 403. When the locking block 403 is not engaged with one of the slots 406, the rotating tube 205 can be rotated. The rotation of the rotating tube 205 will drive the hose 206 to rotate. When the rotating tube 205 rotates 90 degrees, under the action of the torsion spring 404, the connecting shaft 402 will drive the locking block 403 to rotate toward the other slot 406 and engage with it. At this time, the rotating tube 205 cannot rotate, and the hose 206 moves from the inside of the polishing tank 5 to the outside of the polishing tank 5, thereby avoiding damage to the hose 206 during the polishing process and effectively improving the safety of use. Rotate the abutment 305 via the rotating rod 304. As the abutment 305 rotates, it moves away from the cover plate 209. Once the abutment 305 disengages from the inside of the limiting sleeve 306, the rotating shaft 302 can be rotated. The rotating shaft 302 will drive the connecting rod 303 to move. The connecting rod 303 will cause the abutment 305 to deviate from the top of the cover plate 209. Then the cover plate 209 can be moved until the abutment 210 is removed from the inside of the connecting cylinder 202. Next, the filter cover 213 can be removed from the inside of the connecting cylinder 202 by holding the pull rod 214. After the filter cover 213 is removed, it is convenient to clean the debris collected inside.
