separation: the knob is unscrewed, the two grooves on the clutch 7 are separated from the two bosses on the rotating bracket under the action of the elastic force of the spring 61, and the rotating bracket and the front fork can rotate relatively at any angle.
Meshing: when the knob is screwed down, the two grooves on the clutch 7 overcome the elastic force of the spring 61 and are engaged with the two bosses on the rotating bracket, and the rotating bracket can only rotate within a specific angle of the two grooves on the clutch 7.
When the wall polisher is polishing the top of the wall, the top suction positioning function is realized, and the operation mode is as follows: the knob is first tightened so that the two recesses in the clutch 7 engage the two bosses on the rotating bracket against the spring force of the spring 61, and the rotating bracket can only rotate within a certain angle of the two recesses in the clutch 7. The grinding sheet is driven by the rotating bracket to realize the function of ceiling positioning.
When the wall polisher is used for polishing the peripheral wall, the ceiling-suction positioning function needs to be removed, and the operation mode is as follows: the knob is unscrewed, the two grooves on the clutch 7 are separated from the two bosses on the rotating bracket under the action of the elastic force of the spring 61, and the rotating bracket and the front fork can rotate relatively at any angle.
When the scheme is applied to a novel wall surface grinding machine, the clutch mechanism is adopted to realize the positioning function of the grinding disc of the wall surface grinding machine when the top of a wall surface is ground; this is achieved by a pair of ratchet teeth, a spring and a knob. Convenient operation, simplicity, more flexibility, safety and reliability. Therefore, the technical problems that the existing grinding machine is inaccurate in positioning of the grinding disc when the top of the wall surface is ground and inconvenient to operate are solved.
The invention provides a rotating and positioning mechanism of a wall surface grinding machine, which is used for the wall surface grinding machine and realizes the ceiling-suction positioning function of the rotating and positioning mechanism of the wall surface grinding machine through a clutch mechanism.
