Detailed Description
The present invention is described in further detail below with reference to figures 1-3.
Example (b): A3D printer for assisting in printing irregular surfaces is shown in figure 1 and comprises a base 1 and a frame-shaped frame 12 fixedly connected with the base 1, wherein a printing plate 11 is fixedly connected to the upper surface of the base 1. Two X-axis slide rails 13 are arranged at the top end of the frame 12 in parallel, the two X-axis slide rails 13 are movably connected with an X-axis driving mechanism 14, and the X-axis driving mechanism 14 is movably connected with a Y-axis driving mechanism 15 and a feeding box 17.
As shown in fig. 1 and 2, the Y-axis driving mechanism 15 is fixedly connected with a telescopic mechanism 2, an output shaft of the telescopic mechanism 2 is fixedly connected with a direction-changing auxiliary mechanism 4, an end portion of the direction-changing auxiliary mechanism 4 far away from the output shaft of the telescopic mechanism 2 is fixedly connected with a printing nozzle 3, and a material conveying pipe 18 is communicated between the material supply tank 17 and the printing nozzle 3.

The first straight rod 41 is sleeved with a first sleeve 43, the second straight rod 42 is sleeved with a second sleeve 44, the outer walls of the first sleeve 43 and the second sleeve 44 are respectively provided with a placing groove 45 for placing a driving air cylinder 46, and two ends of the driving air cylinder 46 are respectively connected with the inner wall of the corresponding placing groove 45 in a rotating mode. The opposite surfaces of the first straight rod 41 and the second straight rod 42 are both vertically fixed with a connecting rod 47, the free end of the connecting rod 47 is fixedly connected with a universal ball 48, and the two universal balls 48 are connected through a symmetrical universal shell 49. The first sleeve 43 is provided with a circumferential driving mechanism 5 for driving the first sleeve 43 and the first straight bar 41 to rotate relatively circumferentially. The Y-axis driving mechanism 15 is fixedly connected with a main controller 16, and the main controller 16 is electrically connected with the driving sources of the X-axis driving mechanism 14, the Y-axis driving mechanism 15, the telescopic mechanism 2, the driving cylinder 46, the circumferential driving mechanism 5 and the printing nozzle 3. The frictional resistance for limiting the relative circumferential rotation of the universal ball 48 and the symmetrical universal shell 49 is larger than the frictional resistance for limiting the relative circumferential rotation of the second sleeve 44 and the second straight rod 42. The X-axis drive mechanism 14 and the Y-axis drive mechanism 15 jointly drive the print head 3 to move in a horizontal plane. When the print head 3 is driven to change direction, the main controller 16 controls the circumferential driving mechanism 5 to drive the first sleeve 43 to rotate circumferentially relative to the first straight rod 41, and the first sleeve 43 drives the second sleeve 44 to rotate circumferentially relative to the second straight rod 42 under the fixing action of the driving cylinder 46. Then the main controller 16 controls the driving cylinder 46 to stretch and contract, and the driving cylinder 46 stretches and contracts to drive the universal ball 48 and the symmetrical universal shell 49 to rotate relatively, so that the first straight rod 41 and the second straight rod 42 change the direction, and the printing nozzle 3 does not rotate when changing the direction. The influence of the connecting wires and the material conveying pipe 18 of the printing nozzle 3 on the direction change of the printing nozzle 3 is reduced, so that the direction change driving operation of the printing nozzle 3 is simple.

The ball 6 and the annular groove 61 are used for reducing the friction resistance which hinders the relative circumferential rotation of the second sleeve 44 and the second straight rod 42.
As shown in fig. 2, in the present embodiment, the direction change assisting mechanism 4 employs two symmetrically disposed driving cylinders 46, and an included angle formed by a shortest straight line connecting the two driving cylinders 46 to the central axis of the first straight rod 41 is an obtuse angle. With the two drive cylinders 46, the direction change operation of the printing head 3 is made more stable.
As shown in FIG. 2, the included angle is 90-120 degrees. In this embodiment, the included angle degree is 120 degrees, which is convenient for reducing the direction-changing power of the driving cylinder 46 for driving the printing nozzle 3, and reducing the energy consumption of the driving cylinder 46.
As shown in fig. 3, the symmetrical universal housing 49 is sleeved with a protective sleeve 7, and two ends of the protective sleeve 7 are fixedly connected with the opposite ends of the first straight rod 41 and the second straight rod 42 respectively. The protective sleeve 7 is a corrugated pipe or a soft plastic pipe. In this embodiment, the protective cover 7 is a bellows. The protective sleeve 7 is used for conveniently limiting the relative circumferential rotation of the first straight rod 41 and the second straight rod 42, and simultaneously preventing sundries from entering the symmetrical universal shell 49.
The protective sleeve 7 is provided with a plurality of conduits 8 along the circumferential direction thereof, and two ends of the conduits 8 are fixedly connected with the first sleeve 43 and the second sleeve 44 respectively. The conduit 8 is a spirally formed spring-type pipe. The wires are arranged in the spring type pipe, and when the printing nozzle 3 changes direction, elastic deformation can occur within a certain elastic limit.
The working principle is as follows: the X-axis driving mechanism 14 and the Y-axis driving mechanism 15 jointly drive the printing nozzle 3 to move in a horizontal plane; when the printing nozzle 3 is driven to change direction, the main controller 16 controls the circumferential driving mechanism 5 to drive the first sleeve 43 to rotate circumferentially relative to the first straight rod 41, and the first sleeve 43 drives the second sleeve 44 to rotate circumferentially relative to the second straight rod 42 under the fixing action of the driving cylinder 46; then the main controller 16 controls the driving cylinder 46 to stretch and contract, and the driving cylinder 46 stretches and contracts to drive the universal ball 48 and the symmetrical universal shell 49 to rotate relatively, so that the first straight rod 41 and the second straight rod 42 change the direction, and the printing nozzle 3 does not rotate when changing the direction.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
