[0002] A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. It is generally a round metal rod, and each section can have a different diameter. The rotating parts in mechanical equipment / products are mounted on the shaft. To achieve power transmission, flat sections are usually provided at the ends of shaft-type workpieces.

[0003] Chinese utility model patent (authorization announcement number CN213225198U) discloses a positioning mechanism for a fully automatic chamfering machine for chamfering the flat part of shaft workpieces, comprising: a frame; a first friction wheel rotatably mounted on the frame, with its axis horizontally positioned; a second friction wheel rotatably mounted on the frame, with the axes of the first and second friction wheels arranged side-by-side on the same horizontal plane, the first and second friction wheels having the same diameter, no contact between them, and a minimum distance between them less than the diameter of the drive shaft; a sensor mounted on the frame, with its sensing end positioned between the first and second friction wheels, used to detect whether the flat part is set downwards; and a rotary drive mechanism mounted on the frame, used to drive the first and second friction wheels to rotate in the same direction and at the same speed. This positioning mechanism achieves the function of precisely adjusting the position of the flat part of the drive shaft.

[0004] The aforementioned device positions the shaft workpiece using two sets of positioning mechanisms, and then performs chamfering on the flat part of the shaft workpiece. However, a large amount of waste is generated during the chamfering process. This waste not only scatters everywhere, but also tends to be pushed onto the processing table, thus affecting subsequent processing. Utility Model Content

[0005] To address the aforementioned issues, a flat chamfering machine for shaft-type workpieces is provided. A clamping assembly limits the movement of the workpiece during chamfering, preventing it from wobbling. The chamfering assembly then performs the chamfering operation on the flat portion of the workpiece. A dust pump transports the waste generated during the chamfering process to a filter box via the pump and drive unit. The filter plate inside the filter box filters the waste, and the filtered gas is then discharged, preventing the waste from polluting the surrounding environment.

[0006] To address the existing technical problems, this utility model application provides a flat chamfering machine for shaft-type workpieces, including a processing base. A protective frame is provided on the top of the processing base. A clamping assembly for limiting the position of the shaft workpiece is also provided on the top of the processing base.

The input end of the dust pump is connected to a dust suction pipe for adsorbing chamfering debris. The output end of the dust pump is connected to the interior of the drive box via a pipe. The interior of the drive box is connected to the interior of the filter box via a pipe.

[0007] Preferably, the inner wall of the filter box is provided with a plurality of limiting telescopic rods, and the telescopic ends of the limiting telescopic rods are provided with filter plates for filtering waste debris.

[0008] Preferably, a chip settling cylinder is provided on the top of the filter box, a piston push rod is movably arranged inside the chip settling cylinder, a connecting pipe is connected inside the chip settling cylinder, a second one-way valve is provided inside the connecting pipe, and a spray pipe for spraying waste chips is connected to the other end of the connecting pipe.

[0009] Preferably, one end of the chip removal cylinder is connected to a water inlet pipe, one end of which is connected to an external water storage device, and a first one-way valve is installed inside the water inlet pipe.

[0011] Preferably, the filter box is equipped with a collection drawer for collecting waste debris and wastewater.

[0012] The advantages of this utility model application compared to the prior art are:

[0013] The clamping assembly limits the movement of the shaft workpiece during chamfering, preventing it from wobbling. Then, the chamfering assembly is used to chamfer the flat part of the shaft workpiece.

[0022] To further understand the features, technical means, and specific objectives and functions achieved by this utility model application, the following detailed description of this utility model application is provided in conjunction with the accompanying drawings and specific embodiments.

[0023] like Figures 1 to 6 As shown, this utility model application provides:

[0024] A flat chamfering machine for shaft-type workpieces includes a protective frame 2 on the top of a processing base 1, a clamping assembly 3 for limiting the shaft workpiece on the top of the processing base 1, and a chamfering assembly 4 for chamfering the flat part of the shaft workpiece on the top of the processing base 1. A dust pump 7, a drive box 6, and a filter box 5 are respectively arranged on the top of the protective frame 2. The input end of the dust pump 7 is connected to a dust suction pipe 8 for adsorbing chamfering waste, and the output end of the dust pump 7 is connected to the inside of the drive box 6 through a pipe. The inside of the drive box 6 is connected to the inside of the filter box 5 through a pipe.

[0025] By using the clamping assembly 3 to limit the shaft workpiece, the shaft workpiece is prevented from shaking freely during chamfering. Then, the chamfering assembly 4 is used to chamfer the flat part of the shaft workpiece. At the same time, the dust pump 7 is started, and the waste generated during the chamfering process can be transported to the inside of the filter box 5 through the dust pump 7 and the drive box 6. Then, the waste can be filtered by the filter plate 18 inside the filter box 5.

[0026] like Figure 5 As shown, the inner wall of the filter box 5 is provided with multiple limiting telescopic rods 19, and the telescopic ends of the limiting telescopic rods 19 are provided with filter plates 18 for filtering waste debris.

[0027] The filter plate 18 inside the filter box 5 can be used to filter the waste debris, and then the filtered gas is discharged to prevent the waste debris from affecting the surrounding environment.

[0028] like Figure 6 As shown, a chip setter 11 is provided on the top of the filter box 5. A piston pusher 20 is movably arranged inside the chip setter 11. A connecting pipe 23 is connected inside the chip setter 11. A second one-way valve 24 is provided inside the connecting pipe 23. The other end of the connecting pipe 23 is connected to a spray pipe 22 for spraying waste chips.

[0029] When the piston rod 20 moves into the chip settling cylinder 11, the water inside the chip settling cylinder 11 is transported to the spray pipe 22 and then sprayed out to spray the filtered waste chips, so that the waste chips can quickly fall into the collection tray 17 for easy processing.

[0030] like Figure 6 As shown, one end of the chip removal cylinder 11 is connected to a water inlet pipe 9, and one end of the water inlet pipe 9 is connected to an external water storage device. A first one-way valve 10 is installed inside the water inlet pipe 9.

[0031] External water resources can be replenished into the chip removal cylinder 11 through the water inlet pipe 9, making it convenient for the next chip removal operation.

[0032] like Figure 2 and Figure 3As shown, an impeller 16 is rotatably mounted inside the drive box 6. A rotating rod 12 is mounted on the top of the impeller 16. A turntable 13 is mounted on the top of the rotating rod 12. A connecting block 14 is rotatably mounted on the top of the turntable 13. A push block 15 is rotatably mounted on one end of the connecting block 14. The side wall of the push block 15 is connected to one end of the piston push rod 20. A pressing rod 21 is mounted on the side wall of the push block 15. One end of the pressing rod 21 extends into the interior of the filter box 5 and is connected to the side wall of the filter plate 18.

[0033] As the waste chips pass through the drive box 6, they drive the impeller 16 to rotate, which in turn drives the turntable 13 on top of the impeller 16 to rotate. The rotating turntable 13 drives the connecting block 14 and the push block 15 to reciprocate, which in turn drives the piston push rod 20 to reciprocate. When the piston push rod 20 moves toward the inside of the chip settling cylinder 11, the water inside the chip settling cylinder 11 is transported to the inside of the spray pipe 22.

[0034] like Figure 1 and Figure 6 As shown, the filter box 5 is equipped with a collection drawer 17 for collecting waste debris and wastewater.

[0035] Waste and used wastewater can be collected through the collection drawer 17, which facilitates later treatment.

[0036] When chamfering is required on the flat part of a shaft workpiece, the workpiece is first limited by the clamping assembly 3 to prevent it from wobbling during chamfering. Then, the chamfering assembly 4 is used to chamfer the flat part of the workpiece. At the same time, the dust pump 7 is started to transport the waste generated during the chamfering process to the inside of the filter box 5 through the dust pump 7 and the drive box 6. Then, the filter plate 18 inside the filter box 5 can filter the waste, and the filtered gas is discharged to prevent the waste from polluting the surrounding environment. When the waste passes through the drive box 6, it will drive the impeller 16 to rotate, and at the same time drive the turntable 13 on the top of the impeller 16 to rotate. The rotating turntable 13 can drive the connecting block 14 and the push block 15 to reciprocate, thereby driving the piston push rod 20 to reciprocate. As the piston moves towards the inside of the chip settling cylinder 11, the water inside the chip settling cylinder 11 is transported to the inside of the spray pipe 22, and then sprayed out to spray the filtered waste chips, so that the waste chips can quickly fall into the inside of the collection drawer 17 for easy processing. When the piston push rod 20 moves towards the outside of the chip settling cylinder 11, external water resources can be replenished into the inside of the chip settling cylinder 11 through the water inlet pipe 9, which is convenient for the next chip settling operation. At the same time, the push block 15 drives the squeezing rod 21 and the filter plate 18 to reciprocate, thereby preventing the waste chips from clogging the filter holes inside the filter plate 18. Meanwhile, the first one-way valve 10 prevents the water resources inside the chip settling cylinder 11 from being discharged through the water inlet pipe 9, and the second one-way valve 24 prevents external air from entering the inside of the chip settling cylinder 11 through the spray pipe 22.
