Technical Field

[0001] The present application relates to the technical field of machine tool processing, and in particular to a machine tool for chamfering shaft workpieces. Background Art

[0002] At present, when a machine tool performs chamfering on a shaft, there are multiple positions on the shaft that need to be chamfered, for example, the end of the shaft and the end of the hole in the shaft. For the machine tools currently on the market, when performing chamfering on different positions of the shaft, the tool on the machine tool tool holder needs to be replaced accordingly. However, it is very inconvenient to replace the tool, which makes the chamfering efficiency of the machine tool at multiple positions of the shaft low. Utility Model Content

[0006] Preferably, the clamping member includes two clamping plates, a mounting frame, two driving plates, a bidirectional screw and a driving motor. The two clamping plates are vertically symmetrical. The lower part of the clamping plate is rotatably connected to the mounting frame. One end of the two driving plates respectively rotates and slides on the lower end of the two clamping plates. The bidirectional screw passes through the thread and rotates in the two driving plates in turn. The driving motor drives the bidirectional screw to rotate, thereby driving the two driving plates to move closer to or away from each other.

[0007] Preferably, a containing plate is provided at the upper end of the placing plate, and the containing plate is located between the two clamping plates.

[0023] The first processing component 2 includes a first motor 5 and a first cylinder 6. A first mounting plate is horizontally placed below the first motor 5. The first cylinder 6 pushes the first mounting plate to slide, thereby driving the first motor 5 to approach or move away from the adjusting component 4; the second processing component 3 includes a second motor 7 and a second cylinder 8. A second mounting plate is horizontally placed below the second motor 7. The second cylinder 8 pushes the second mounting plate to slide, thereby driving the second motor 7 to approach or move away from the adjusting component 4.

The clamp 9 is located on the placement plate 10, and the placement plate 10 is fixed to the output end of the rotary cylinder 11 by bolts. A linear module 12 is placed on the upper end surface of the storage platform, and the rotary cylinder 11 is fixed to the slide of the linear module 12 by bolts. Under the action of the linear module 12, the clamp 9 is moved to one side of the storage platform, and then the shaft is placed in the clamp 9. Then, under the drive of the linear module 12, the clamp 9 with the shaft is moved between the first processing assembly 2 and the second processing assembly 3.

[0025] Reference Figure 2 and Figure 3 The clamping member 9 includes two clamping plates 13, a mounting frame 14, two driving plates 15, a bidirectional screw 16 and a driving motor 17. The mounting frame 14 is fixed on the placement plate 10. The upper end surface of the mounting frame 14 is provided with a rotating groove 18 for the two clamping plates 13 to rotate. The upper ends of the two driving plates 15 are respectively provided with waist-shaped holes 19. The lower ends of the clamping plates 13 rotate and slide in the waist-shaped holes 19 of the driving plates 15. A screw nut is fixed in the lower end of the driving plate 15. The bidirectional screw 16 passes through the thread in turn and rotates in the screw nuts of the two driving plates 15. The bidirectional screw 16 is composed of two sections of reverse threaded rods 24. One end of the bidirectional screw 16 is fixed to the outer end of the output end of the driving motor 17 through a coupling. First, place the shaft between the two clamping plates 13, then start the drive motor 17 to drive the bidirectional screw 16 to rotate. Under the threaded cooperation between the bidirectional screw 16 and the drive plate 15, the two drive plates 15 are moved away from each other, and then the two clamping plates 13 are rotated to tighten the shaft.
