Detailed Description
The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.
The photocuring 3D printer shown in FIG. 5 comprises a printing platform 3, a liquid containing tank 11, a lifting mechanism and a locking assembly 12. The liquid tank 3 contains raw material liquid for printing, such as resin liquid, and the lifting mechanism comprises a vertical fixed slide rail 13 and a slide block 14, and the slide block 14 is in sliding fit with the vertical fixed slide rail 13. Printing platform 3 is fixed through locking assembly 12 locking, and locking assembly 12 is fixed with slider 14, and printing platform 3 can move along vertical fixed slide 13. The locking assembly 12 may be any locking means such as a threaded lock or a cam handle lock.
As shown in fig. 1 and 2, the photocuring 3D printer further includes a printing platform leveling device for leveling the bottom of the printing platform 3 and the liquid containing tank 11, and includes an upper adjusting bracket 1 and a lower adjusting bracket 2, the upper and lower directions are set in the direction shown in fig. 1, the lower adjusting bracket 2 is fixed on the top of the printing platform 3, the printing platform 3 and the lower adjusting bracket 2 can be fixed by screws or bolts, the top surface of the upper adjusting bracket 1 is located above the lower adjusting bracket 2, the upper adjusting bracket 1 and the lower adjusting bracket 2 are fixed by screws 8, the lower adjusting bracket 2 can move a certain distance relative to the upper adjusting bracket 1 along the axial direction oo' of the printing platform leveling device, that is, the fixing position between the upper adjusting bracket 1 and the lower adjusting bracket 2 can be adjusted, so as to adjust the heights of the four corners of the lower adjusting bracket 2, and make the printing platform 3 parallel to the liquid containing tank 11, finally, the position of the printing platform 3 is fixed by the screws 8. The height of the four corners of the lower adjusting bracket 2 can be accurately adjusted, so that the printing platform 3 can be accurately leveled.
Specifically, the upper adjusting bracket 1 comprises an adjusting sheet mounting part 4, the lower adjusting bracket 2 comprises adjusting sheets 5, the number of the adjusting sheets 5 is 2, the adjusting sheets 5 are arranged along the axial direction of the printing platform leveling device, and the adjusting sheets 5 are mounted on the adjusting sheet mounting part 4. The provision of the adjustment sheet 5 and the adjustment sheet mounting portion 4 facilitates mounting between the upper adjustment bracket 1 and the lower adjustment bracket 2. Each adjusting sheet 5 is provided with 2 limiting grooves 6, the length direction of each limiting groove 6 is the same as the setting direction of each adjusting sheet 5, namely the length direction of each limiting groove 6 is the same as the axial direction of the printing platform leveling device, the upper adjusting support 1 is provided with a mounting hole 7, each mounting hole 7 is provided with threads, and the screws 8 penetrate through the limiting grooves 6 and the mounting holes 7 to be fixed. Because the limiting groove 6 has a certain length along the axial direction, the length of the limiting groove 6 is greater than the diameter of the screw 8, and the screw 8 can move in the limiting groove 6 along the axial direction, the height of the four corners of the lower adjusting bracket 2 can be adjusted after the screw 8 penetrates through the limiting groove 6, and the screw 8 is screwed after the leveling is finished to fix the position of the lower adjusting bracket 2. The length setting of the limit groove 6 limits the maximum distance that the lower adjustment bracket 2 can move axially relative to the upper adjustment bracket 1.
As shown in fig. 3, the tab mounting portion 4 is provided with a pressure spring mounting groove 9, and the pressure spring mounting groove 9 is provided in the axial direction. As shown in fig. 2, the printing platform leveling device further includes a pressure spring 10, at least a portion of the pressure spring 10 is located in a pressure spring installation groove 9, an upper end portion of the pressure spring 10 is located in the pressure spring installation groove 9, one end of the pressure spring 10 abuts against an upper end surface of the adjustment sheet 5, and the other end of the pressure spring 10 abuts against a groove wall of the pressure spring installation groove 9 of the upper adjustment bracket 1. If the pressure spring 10 is not arranged between the upper adjusting bracket 1 and the lower adjusting bracket 2, the printing platform 3 lacks a downward pretightening force during leveling, and needs one hand to press the printing platform 3 to be fastened again, otherwise, the leveling fails. The downward pretightening force is applied to the lower adjusting support 2 by the pressure spring 10, and the printing platform 3 does not need to be pressed by hands, so that the printing platform 3 is conveniently leveled, and the operation is simple. The compression spring 10 is installed in the compression spring installation groove 9, and the displacement of the compression spring 10 in the radial direction is limited.
When the leveling device is installed, the pressure spring 10 is installed in the pressure spring installation groove 9, the upper adjusting support 1 is installed on the lower adjusting support 2, the pressure spring 10 presses the adjusting sheet 5, and the screw 8 penetrates through the limiting groove 6 of the lower adjusting support 2 and is screwed with the installation hole 7 of the upper adjusting support 1. When leveling print platform 3, print platform 3 and locking subassembly 12 are locked fixedly, unscrew 4 screws 8 earlier, and the system that sets up the photocuring 3D printer moves whole print platform 3 to z axle coordinate zero point, and this moment because print platform 3 and liquid containing groove 11 bottom are hugged closely can be ensured to the pretightning force of pressure spring 10, need not manually press print platform 3, then locking screw 8 can. The manual pressing of the printing platform 3 is also easy to cause errors according to personal strength, so that the leveling is inaccurate, and the operation of locking the screw 8 by one hand is inconvenient, but in the embodiment, the pretightening force is applied by the pressure spring 10 of the printing platform leveling device, so that the manual pressing of the printing platform 3 is more accurate.
The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made on the basis of the present invention to solve the same technical problems and achieve the same technical effects are all covered by the protection scope of the present invention.
