Pavement cutting machine with precise cutting depth positioning control
The invention discloses a pavement cutting machine with precise cutting depth positioning control; the pavement cutting machine comprises a machine body (1) and a base (2) supporting the machine body; the machine body is provided with a threaded rod (3) and a lead screw (4) matched with the threaded rod; the pavement cutting machine is characterized in that a contact section of the lead screw (4) and the threaded rod (3) is provided with a depth positioning device, the depth positioning device comprises a spring (5), a contact (6) and a contact switch (7), the spring (5) is located above the lead screw (4) and tightly wraps the lead screw (4), the spring (5) and the lead screw (4) are located in a cavity of the threaded rod (3), the contact switch (7) is arranged outside the threaded rod (3) and is provided with the contact (6), and the contact (6) extends to the interior of the threaded screw. The contact is controlled by the contact switch, and thus the elastic deformation of the spring is controlled, and a position of the lead screw and the threaded rod is guaranteed to be fixed, and the set cutting depth is guaranteed to be unchanged.
