A wood plywood milling machine with precise thickness control is a device specifically designed for precise processing of wood plywood. It can achieve precise control of the thickness of the plywood to ensure that the thickness of the processed board is uniform.

[0003] During the milling process of wooden plywood, when the milling head of the milling machine contacts the plywood, its high-speed rotation may cause the wooden plywood to vibrate.

If this situation is not controlled, it will affect the milling thickness of the wooden plywood and it will be difficult to control. Therefore, to address the above problem, a wooden plywood milling machine with precise thickness control is proposed. Utility Model Content

[0032] As a further implementation of this solution, the fixed machine assembly 2 includes a machine frame 21, the front end of the machine frame 21 is fixedly connected to a support plate 22, the top of the machine frame 21 is fixedly connected to a convex plate 23, one side of the convex plate 23 is fixedly connected to a hydraulic rod 24, one side of the hydraulic rod 24 is fixedly connected to a metal plate 25, one side of the metal plate 25 is fixedly connected to a rubber plate 26, one side of the rubber plate 26 is fitted with the outer side of the wooden plywood body 27, the top of the support plate 22 is fixedly connected to the bottom end of the robotic arm 1, and the number of the convex plate 23, hydraulic rod 24, metal plate 25 and rubber plate 26 are all four.

The mechanical arm 1 fixed on the support plate 22 is started, and the displacement control component 4 is driven to move through the fixing frame 3 to accurately control the milling position. At the same time, the rubber plate 26 plays a buffering role in the squeezing of the wooden plywood body 27, preventing damage to the wooden plywood body 27 during fixation.

[0033] As a further implementation of this solution, two straight holes are defined on the inner side of the fixed disk 41. The outer sides of the threaded rods 43 are fitted into the inner sides of the straight holes of the fixed disk 41. The outer sides of the limiting straight posts 44 are slidably connected to the inner sides of the inner straight hole blocks 47. The bottom ends of the threaded rods 43 and the limiting straight posts 44 are flush with the bottom ends of the fixed spring housings 51. The bottom ends of the milling mechanisms 46 are flush with the bottom ends of the fixed spring housings 51, ensuring that the milling head is positioned directly above the area to be milled, achieving precise milling. The milling depth of the wooden plywood body 27 by the milling mechanism 46 is controlled by the rotation of the main shaft of the servo motor 42, ensuring precise control of the milling thickness.

[0034] As a further implementation of this solution, two cylindrical grooves are provided on the inner side of the fixed spring housing 51, the bottom end of the fixed spring housing 51 is a through structure, the built-in sliding column 56 is slidably connected to the inner side of the fixed spring housing 51, the outer side of the outer convex column 57 is in contact with the inner side of the lower end of the fixed spring housing 51, the pressure spring 55 is sleeved on the outer side of the spring limiting rod 52, the built-in sliding column 56 and the outer convex column 57 are both cylindrical in shape, the pressure sensor 53 is electrically connected to the servo motor 42 through an electric wire, the servo motor 42 is electrically connected to the controller on the robot arm 1, the shape of the stabilizing ring 6 is a circular ring, and the lower end of the stabilizing ring 6 A ball groove is provided on the inner side thereof, and the steel ball 7 is spherical in shape. The number of the steel balls 7 corresponds to the number of the ball grooves at the lower end of the stabilizing ring 6. The elastic deformation of the pressure spring 55 plays a buffering role when the built-in sliding column 56 squeezes the pressure spring 55, reducing the damage to the surface of the wooden plywood body 27 when the steel ball 7 contacts the wooden plywood body 27, and preventing the wooden plywood body 27 from moving slightly up and down due to vibration after the milling head of the milling mechanism 46 contacts the wooden plywood body 27, thereby ensuring precise control of the milling thickness of the wooden plywood body 27.

[0035] Workflow: To prevent the high-speed rotation of the milling head from causing vibration and displacement of the wooden plywood, which may lead to different milling precision, when controlling, first place the wooden plywood body 27 on the top of the machine frame 21, and start the hydraulic rods 24 at the front and rear ends at the same time. The hydraulic rods 24 drive the metal plate 25 and the rubber plate 26 to move. After the rubber plates 26 at the front and rear ends are in contact with the front and rear ends of the wooden plywood body 27, start the hydraulic rods 24 at the left and right ends to make the four rubber plates 26 simultaneously in contact with the wooden plywood body 27. When passing through the hydraulic rods 24, the rubber plates 26 squeeze the wooden plywood body 27. The rubber plates 26 play a role of buffering the wooden plywood body 27, preventing damage to the wooden plywood body 27 when it is fixed around. The robot arm 1 fixed on the support plate 22 is started at this time, and the robot arm 1 drives the displacement control component 4 to move through the fixed frame 3. The position of the displacement control component 4 is accurately controlled by the controller at the lower end of the robot arm 1. When the displacement control component 4 moves to the top of the wooden plywood body 27 that needs to be milled, the displacement control component 4 is moved vertically downward by the robot arm 1. When the lower end of the steel ball 7 is in contact with the top of the wooden plywood body 27, the steel ball 7 squeezes the stabilizing ring 6, and the stabilizing ring 6 squeezes the outer protrusion 57. The outer protrusion 57 drives the built-in sliding column 56 to slide and connect to the inner side of the fixed spring housing 51. The built-in sliding column 56 squeezes the pressure spring 55, causing the pressure spring 55 to undergo elastic deformation. The outer side of the pressure spring 55 moves outside the spring limit rod 52. When After the top of the built-in sliding column 56 contacts the pressure sensor 53, the robot arm 1 stops pushing the displacement control component 4 downward, and the partial fixation of the wooden plywood body 27 is completed. Under the action of the elastic force of the pressure spring 55, the steel ball 7 plays a buffering role when contacting the wooden plywood body 27, preventing damage to the surface of the wooden plywood body 27. The steel ball 7 rolls inside the stabilizing ring 6, facilitating the overall movement of the displacement control component 4 and the lower end device, and preventing friction between the stabilizing ring 6 and the wooden plywood body 27 when moving. After the above-mentioned built-in sliding column 56 contacts the pressure sensor 53, the servo motor 42 is started to drive the threaded rod 43 to rotate, and the rotation of the threaded rod 43 drives the internal threaded block 45 connected to the outer spiral to move The inner thread block 45 drives the milling mechanism 46 and the inner straight hole block 47 to move downward, and the outer side of the inner straight hole block 47 is slidably connected to the outer side of the limit straight column 44, which plays a role in limiting the movement of the milling mechanism 46. At this time, the milling head at the lower end of the milling mechanism 46 moves from the inside of the stabilizing ring 6 to realize the milling of the wooden plywood body 27. The milling depth of the wooden plywood body 27 by the milling mechanism 46 is controlled by the rotation of the main shaft of the servo motor 42. Under the squeezing action of multiple steel balls 7, the milling head of the milling mechanism 46 is prevented from contacting the wooden plywood body 27, which causes the wooden plywood body 27 to move slightly up and down due to vibration.This ensures precise control of the milling thickness of the wood plywood body 27.

[0036] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
