A second slider 210 is fixedly connected to the middle of the crossbar 23, and the middle of the second slider 210 is connected to the lower end of the first screw 25. When it is necessary to drive the grinding wheel assembly to move up and down, the first turntable 26 is manually rotated, which drives the first screw 25 connected to it to rotate. At the same time, the first screw 25 drives the second slider 210 and the first slider 29 to move up and down, thereby realizing the up and down movement of the grinding wheel assembly.

[0031] In addition, a second turntable 211 is provided on the outer side of the first slider 29, and a second screw 212 connected to the second turntable 211 is provided on the inner side. The other end of the second screw 212 is connected to one side of the second slider 210. A third slider 213 is provided on the second screw 212. The grinding wheel assembly is installed on the third slider 213. When it is necessary to drive the grinding wheel assembly to move left and right, the second turntable 211 is manually rotated, which drives the second screw 212 connected to it to rotate. At the same time, the second screw 212 drives the third slider 213 on it to move left and right, thereby realizing the left and right movement of the grinding wheel assembly.

[0032] Reference Figure 2 The left and right grinding wheel assemblies 27 and 28 of the grinding wheel adjustment mechanism have identical structures, including a third mounting plate 271, a second motor 272, a second driving wheel 273, a second driven wheel 274, a second synchronous belt 275, a second rotating shaft 276, a second rotating shaft mounting seat 277, and a grinding wheel 278.

A grinding wheel protective cover 279 is provided on the outside of the grinding wheel 278. A limiting block 2710 is provided on one side of the third slider 213. Handles 2712 are provided on the first turntable 26 and the second turntable 211.

[0033] Furthermore, the left grinding wheel assembly 27 and the right grinding wheel assembly 28 are symmetrically arranged and have the same structure. Each assembly includes a third mounting plate 271, a second motor 272, a second driving wheel 273, a second driven wheel 274, a second synchronous belt 275, a second rotating shaft 276, a second rotating shaft mounting base 277, and a grinding wheel 278. The second motor 272 is mounted on the third mounting plate 271. The output shaft of the second motor 272 is connected to the second driving wheel 273. The second driving wheel 273 and the second driven wheel 274 are connected via the second synchronous belt 275. The second driven wheel 274 is connected to one end of the second rotating shaft 276, and the other end of the second rotating shaft 276 is connected to the grinding wheel 278. A protective cover 279 is provided on the outer side of the grinding wheel, and a notch is provided on the inner side of the protective cover 279 to expose the grinding wheel 278. The exposed portion is used for grinding the workpiece. Kinetic energy protection covers 2711 are also provided on the outer sides of the second driving wheel 273 and the second driven wheel 274 to protect the operator's safety. When it is necessary to drive the grinding wheel to grind the workpiece, the second motor 272 is turned on, driving the second driving wheel 273, the second driven wheel 274, the second synchronous belt 275, the second rotating shaft 276, and the grinding wheel 278 to rotate, so that the inner side of the grinding wheel chamfers and grinds the end of the workpiece. Since there are two sets of grinding wheel assemblies, the workpiece should be installed between the two grinding wheels. In addition, a limiting block 2710 is set on one side of the third slider 13 to prevent the third slider 213 from hitting the first slider 29 during left and right movement, thus providing protection. Moreover, the limiting block 2710 has an open structure and can be directly locked onto the crossbar 23 for easy installation and removal. Handles 2712 are set on the first turntable 26 and the second turntable 211, mainly to facilitate the operator to manually operate the discs.

[0034] Reference Figure 5 The feeding mechanism 3 includes a first motor 31, a first driving wheel 32, a first driven wheel 33, a first synchronous belt 34, a first rotating shaft 35, a first rotating shaft mounting base 36, and a workpiece mounting plate 37. The output shaft of the first motor 31 is connected to the first driving wheel 32. The first driving wheel 32 and the first driven wheel 33 are connected through the first synchronous belt 34. The middle part of the first driven wheel 33 is connected to one end of the first rotating shaft 35. The other end of the first rotating shaft 35 passes through the first rotating shaft mounting base 36 to its outside and is connected to the workpiece mounting plate 37. The outer periphery of the workpiece mounting plate 37 has a plurality of arc-shaped grooves 38 arranged in a ring. A cylindrical workpiece 7 is placed in the arc-shaped grooves 38.

[0035] Furthermore, during the processing of the workpiece, the first motor 31 of the feeding mechanism 3 drives the first driving wheel 32 to rotate, and the first driving wheel 32 drives the first driven wheel 33, the first rotating shaft 35, the workpiece mounting plate 37 and the workpiece 7 to rotate, so that the grinding wheel 278 performs chamfering on both ends of the workpiece 7. Since multiple workpieces can be placed on the workpiece mounting plate 37, the grinding wheel 278 can process multiple workpieces at once, improving the efficiency of workpiece chamfering.

[0036] Reference Figure 6 The belt support mechanism 4 includes a first mounting plate 41, a second mounting plate 42, a drive motor 43, a roller 44, a first roller 45, a second roller 46, and a belt 47. The first mounting plate 41 is mounted on the bracket 6, the second mounting plate 42 is mounted on one side of the first rotating shaft mounting seat 36, the drive motor 43 is mounted on one side of the first mounting plate 41, the roller 44 is connected to the output shaft of the drive motor 43, the first roller 45 is mounted above the roller 44 and connected to the first mounting plate 41, the second roller 46 is mounted on the second mounting plate 42, and the middle parts of the roller 44, the first roller 45, and the second roller 46 are connected by the belt 47. The lower side of the belt 47 presses on the workpiece 7. The outer periphery of the roller 44 has a plurality of first protrusions 441 arranged in a ring along its length direction. The inner wall of the belt 47 is provided with second protrusions that are adapted to the first protrusions 441. The middle part of the first roller 45 and the second roller 46 are both provided with first limiting rings 461. The middle part of the roller 44 is provided with second limiting rings 442. The belt 47 is located inside the first limiting rings 461 and the second limiting rings 442.

[0037] The belt support mechanism 4 is used to support the belt 47 and place it above the workpiece 7, pressing the workpiece 7 down. When processing the workpiece, the drive motor 43 drives the roller 44 to rotate. Due to the action of the first protrusion 441 on the inner wall of the belt and the second protrusion on the outer side of the roller 44, the belt 47 will rotate in the first limiting ring 461 in the middle of the first roller 45 and the second roller 46. The lowermost side of the belt 47 presses on the surface of the workpiece, pressing the workpiece down and preventing the workpiece from coming out of the arc-shaped groove 38 during processing, thus limiting the workpiece. It should be noted that the rotation direction of the belt 47 is opposite to the rotation direction of the workpiece, so that the workpiece can rotate in the arc-shaped groove 38 when passing under the belt, ensuring that the end faces of both ends of the workpiece can be processed.

[0038] Reference Figure 1 The double-head chamfering machine has a discharge channel 8 on the front side of the base 1 and a feeding channel on the rear side. The front end of the discharge channel 8 and the rear end of the feeding channel correspond to the arc-shaped groove 38. The discharge channel 8 is inclined downwards, and the feeding channel is inclined upwards, which facilitates loading and unloading.
