The discharging component includes a pushing rod, a discharging bin, a buffer slope, and a conveyor belt, which are used to push the processed material shaft into the discharging bin and transport it out of the device through the conveyor belt to achieve automatic discharging. The entire system reduces the labor intensity of workers and improves production efficiency through the automated processes of feeding, processing, and discharging.

[0005] However, there may be a possibility of releasing multiple material shafts at one time when releasing the material shaft, and during transportation, the entire feeding turntable rotates, resulting in a relatively high probability of damage. Content of the Utility Model

Detailed implementation manners

[0025] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0026] Refer to Figures 1-8 : A chamfering machine for machining shaft workpieces, comprising an unloading mechanism 1 for unloading the shaft workpieces to be machined. The shaft workpieces after unloading are carried by a load-carrying mechanism 2. The shaft workpieces on the load-carrying mechanism 2 are transported to a processing mechanism 5 by a moving mechanism 3. The processing mechanism 5 is used for machining the shaft workpieces to be machined. The unloading mechanism 1 includes an unloading box 11 for loading the shaft workpieces to be machined. An unloading chute 12 is arranged in the unloading box 11. The unloading chute 12 is used for guiding the movement of the shaft workpieces to be machined stored in the unloading box 11. A material distribution block 13 is arranged at the outlet position of the unloading box 11. The material distribution block 13 is used to ensure that only one shaft workpiece to be machined flows out of the outlet of the unloading box 11 each time. The material distribution block 13 is connected with a rotating rod 14. A guide rod 141 is arranged on the rotating rod 14. A cylinder 15 is arranged outside the rotating rod 14. The air rod drives the moving rod 151 to expand and contract. The moving rod 151 is fixedly connected with a guide cylinder 152. A guide groove 153 is arranged in the moving cylinder. The guide groove 153 is adapted to the guide rod 141. The cylinder 15 drives the guide cylinder 152 to move through the air rod. The guide cylinder 152 drives the guide rod 141 to rotate through the guide groove 153. The guide rod 141 drives the rotating rod 14 to rotate. The rotation of the rotating rod 14 drives the material distribution block 13 to work.

[0027] In the prior art, the unloading device of the device may cause multiple shaft workpieces to be unloaded during a one-time unloading process, resulting in processing errors. In this utility model, first, the shaft workpiece to be processed is fed through the unloading box 11 in the unloading mechanism 1. An unloading chute 12 is provided inside the unloading box 11 for guiding the movement of the shaft workpiece. A material distribution block 13 is installed at the outlet position of the unloading box 11 to ensure that only one shaft workpiece flows out each time. The material distribution block 13 is connected to a rotating rod 14. A guiding rod 141 is installed on the rotating rod 14, and a cylinder 15 is arranged outside. The cylinder 15 drives the movable rod 151 to expand and contract through a pneumatic rod, thereby controlling the operation of the material distribution block 13. The movable rod 151 is fixedly connected to a guiding cylinder 152. A guiding groove 153 is provided inside the guiding cylinder 152 and is adapted to the guiding rod 141. The cylinder 15 drives the guiding cylinder 152 to move, and the guiding rod 141 rotates along with the guiding groove 153, thereby driving the rotating rod 14 to rotate, and finally realizing the material distribution action of the material distribution block 13. The shaft workpiece after unloading is carried by the loading mechanism 2 and transported to the processing mechanism 5 through the moving mechanism 3 for processing. The entire system controls the rotation of the material distribution block 13 through the telescopic action of the cylinder 15 to ensure that the shaft workpieces can flow out of the unloading box 11 in an orderly manner, and then are carried by the loading mechanism 2 and transported to the processing mechanism 5 through the moving mechanism 3 for processing. This process realizes the automatic unloading and orderly material distribution of the shaft workpieces, improving the processing efficiency and accuracy.

[0028] Refer to Figures 1-8 : The loading mechanism 2 includes a receiving seat 21 for receiving the shaft workpiece. A rotating shaft 22 is provided on the receiving seat 21. A balance weight 23 is provided at the bottom of the receiving seat 21. The balance weight 23 is used to ensure that the receiving seat 21 is always in a horizontal position.

[0029] In this chamfering machine for machining shaft workpieces, the function of the loading mechanism 2 is to receive and stabilize the shaft workpieces, ensuring that the shaft workpieces remain stable during transportation. The loading mechanism 2 includes a receiving seat 21, which is the part used to carry the shaft workpieces. A rotating shaft 22 is provided on the receiving seat 21, which allows the receiving seat 21 to rotate when needed to adapt to different machining or transportation requirements. To ensure that the receiving seat 21 remains horizontal at all times, a balance weight 23 is installed at the bottom of the receiving seat 21. The role of the balance weight 23 is to adjust the position of the receiving seat 21 to counteract the tilt caused by the weight or uneven distribution of the shaft workpieces. In this way, regardless of the weight of the shaft workpieces, the receiving seat 21 can remain horizontal, thereby reducing possible errors or damages during transportation. When the shaft workpieces are separated by the unloading mechanism 1 and flow out from the unloading box 11, they will be received by the receiving seat 21 of the loading mechanism 2. The receiving seat 21 can be adjusted to a suitable position by the rotation of the rotating shaft 22 to facilitate the loading and unloading of the shaft workpieces. At the same time, the balance weight 23 ensures that the receiving seat 21 will not tilt due to the weight of the shaft workpieces, guaranteeing the smoothness of the entire loading process and the safety of the shaft workpieces. In this way, the shaft workpieces can be safely transported to the machining mechanism 5 for the next step of machining.

[0030] Refer to Figure 8 : The moving mechanism 3 includes a servo motor 31 provided at the central position of the chamfering machine. A rotating base 32 is provided on the servo motor 31. A rod body 33 is fixedly connected to the rotating base 32. A sliding groove 331 is opened on the rod body 33. The rod body 33 is slidably connected to a sliding sleeve rod 34 through the sliding groove 331. The sliding sleeve rod 34 is rotatably connected to the rotating shaft 22. A limiting groove 35 for limiting the movement of the rotating shaft 22 is provided on the chamfering machine.

[0031] The servo motor 31 drives the rotating base 32 and the rod body 33, so that the sliding groove 331 on the rod body 33 drives the sliding sleeve rod 34 to move axially along the rod body 33. At the same time, the sliding sleeve rod 34 drives the rotating shaft 22 on the receiving seat 21 to move along the limiting groove 35, realizing the precise transportation of the shaft workpieces inside the chamfering machine. The limiting groove 35 ensures that this process is carried out within the control range to prevent accidents. Through such a design, the chamfering machine can efficiently and accurately move the shaft workpieces from one position to another for subsequent machining operations.

[0032] Refer to Figures 1-7 : The chamfering machine further includes a fixing mechanism 4. The fixing mechanism 4 includes a moving block 41 provided on the working plane. A moving groove 42 adapted to the moving block 41 is provided at the bottom of the fixing mechanism 4. The fixing mechanism 4 further includes a fixing block 43 for limiting the shaft workpieces transported to the machining position.

[0033] The fixing mechanism 4 moves on the working plane through the cooperation of the moving groove 42 and the moving block 41. When the shaft workpiece is transported to the processing position, the fixing mechanism 4 can move to the processing position through the cooperation of the moving groove 42 and the moving block 41. At this time, the fixing block 43 on the fixing mechanism 4 fixes the shaft workpiece.

[0034] Refer to Figure 6 : A workpiece discharging mechanism is provided at the bottom of the chamfering machine. The workpiece discharging mechanism is a lower workpiece rod 6 fixedly connected to the device. When the processed shaft workpiece is transported to the workpiece discharging mechanism, the lower workpiece rod 6 restricts the movement of the shaft workpiece, and the loading mechanism 2 continues to move and separates from the shaft workpiece.

[0035] After the shaft workpiece is processed by the processing mechanism 5, it is transported to the position of the workpiece discharging mechanism along with the movement of the loading mechanism 2. At this time, the lower workpiece rod 6 contacts the shaft workpiece and, through its limiting effect, prevents the shaft workpiece from moving forward. Since the lower workpiece rod 6 is fixed to the chamfering machine device and does not move with the movement of the loading mechanism 2, when the loading mechanism 2 continues to move forward, the shaft workpiece will stay in place due to the limitation of the lower workpiece rod 6 and separate from the loading mechanism 2. This design allows the processed shaft workpiece to be quickly removed without interfering with the subsequent processing process, improving production efficiency. At the same time, through the limiting function of the lower workpiece rod 6, the stability of the shaft workpiece during the separation process is ensured, avoiding workpiece damage or reduction in processing accuracy caused by improper separation.

[0036] Refer to Figure 6 : A loading mechanism is provided below the workpiece discharging mechanism. The loading mechanism is a material box 7 for loading materials.

[0037] The material box 7 provides a storage space for the processed materials.

[0038] The above embodiments only represent one or several implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be subject to the appended claims.
