Embodiment 1

[0030] see figure 1 , Embodiment 1 As shown in the figure, it can be seen that the double-rotating bead grinding machine of the present invention includes a frame 1, a power transmission mechanism 10, a bead grinding roller 2, a bead grinding sleeve 3, a screening device, a transmission 11, a bearing 12 and a flange 13 , the power transmission mechanism 10 is arranged at the bottom of the frame 1, the grinding bead roller 2 is arranged on the frame 1, the grinding bead sleeve 3 is set on the grinding bead roller 2, the screening device is connected with the grinding bead outlet of the screw channel 4, and the grinding Bearings 12 are provided at the top and bottom of the bead sleeve 3, and the flange 13 is arranged on the bead sleeve 3, so that the rotation resistance is reduced, the power consumption is less, and the wear of the bead sleeve 3 and the bead roller 2 is reduced. , The connection between the bearing 12 and the ball bearing sleeve 3 is also tightly fixed, and it i...

Embodiment 2

[0036] The difference between the second embodiment and the first embodiment is that: the rotation direction of the grinding bead sleeve 3 is consistent with the downward rotation direction of the screw channel 4 , and the rotation speed of the grinding bead sleeve 3 is greater than that of the grinding bead roller 2 . The rotational speed of the grinding bead sleeve 3 must be greater than the rotational speed of the grinding bead roller 2, so that the bead to be ground can be ground downward along the threaded channel 4, otherwise the bead to be ground will be moved out of the device by the bead grinding roller 2 and enter the Not in screw channel 4.

[0037] During use, open the power transmission mechanism 10, so that the power transmission mechanism 10 drives the grinding bead roller 2 and the grinding bead sleeve 3 to rotate together, put the bead body to be ground into the grinding bead sleeve 3, and make the bead body to be ground along the grinding bead roller. 2. The ...

Embodiment 3

[0039] The difference between Embodiment 3 and Embodiment 1 is that there is no transmission 11, and the number of power transmission mechanisms 10 is two. The first power transmission mechanism is in transmission connection with the grinding bead roller 2, and the second power transmission mechanism is in transmission connection with the grinding bead sleeve 3. . In this way, the first power transmission mechanism and the second power transmission mechanism can be used respectively to make the bead grinding sleeve 3 and the bead grinding roller 2 rotate in opposite directions. The rotational speed of the bead body is greater than the rotational speed of the grinding bead sleeve 3, so that the bead body to be ground can be ground down along the threaded channel 4, otherwise the bead body to be ground will be moved out of the device by the grinding bead sleeve 3, and cannot enter the threaded channel 4 middle.

[0040] During use, open the first power transmission mechanism an...

Abstract

The invention discloses a double-rotation bead grinding machine. The double-rotation bead grinding machine comprises a machine frame, a power transmission mechanism, a bead grinding roller and a bead grinding sleeve. The bead grinding roller is arranged on the machine frame. The bead grinding sleeve is arranged on the bead grinding roller in a sleeving manner and is in interference fit with the bead grinding roller. A threaded channel is arranged on the surface of the bead grinding roller. The diameter of the threaded channel is matched with the diameter of a bead to be ground. An inlet and an outlet of the threaded channel are formed in the top and the bottom of the bead grinding roller respectively. The power transmission mechanism is in transmission connection with the bead grinding roller and is in transmission connection with the bead grinding sleeve. The bead grinding roller is further provided with a speed changer, the bead grinding sleeve and the bead grinding roller can rotate in the opposite direction, the rotating direction of the bead grinding roller is consistent with the downward spiral direction of the threaded channel, and the rotating speed of the bead grinding roller is higher than that of the bead grinding sleeve. By means of cooperation of the rotating speed of the bead grinding sleeve and the rotating speed of the bead grinding roller, a bead body passes the threaded channel, then the smooth surface can be ground, and the bead grinding process is greatly simplified. Meanwhile, the double-rotation bead grinding machine is simple in structure, the damage to the bead body is avoided, and continuous bead grinding can be carried out.

Description

technical field [0001] The invention relates to the technical field of grinding machines, in particular to a double-rotating bead grinding machine. Background technique [0002] At present, the grinding methods include manual grinding and bead grinding machine grinding. Manual grinding results in a high rate of defective products, high cost, and requires too high skill level of workers, which is not suitable for large-scale industrial production. However, the existing bead grinding machines generally have grinding discs on the frame, and the grinding discs are connected with the lifting mechanism, so that the grinding discs can be lifted and lowered automatically, which virtually reduces the operator's work intensity. In addition, the bead grinding machine of this structure not only replaces the manual operation, but also further improves the production efficiency and reduces the production cost, but has the following defects. The volume of the whole machine is large, the st...
