Connecting mechanism for drawer front faceplate and drawer side surface plate

InactiveCN101181116AImprove fastnessEasy left and right adjustmentDrawersFurniture joiningEngineeringSymmetric structure
The invention discloses a connecting device of a drawer front panel and a drawer side panel, which consists of a forward-aligned code fixedly arranged on the drawer front panel and a locking bracket fixedly arranged on the drawer side panel; the forward-aligned code is provided with a end face trigger and a locking groove which has the locking slot structure that has two-side symmetry; the locking groove comprises a bottom board, a main bracket, a rotary sliding block, a spring and a lever; the forward alignment code is inserted into the guiding groove of the main groove; the end face trigger of the forward-aligned code collides with the triggering baffle of the rotary sliding block, causing the rotary sliding block to rotate and the locking buckle of the rotary sliding block buckles the locking groove of the forward alignment code, locking the forward-aligned code and connecting the drawer front panel and the drawer side panel. The rotary sliding block of the invention adopts a fan-shaped sliding block of double-layer symmetric structure and the forward-aligned code is of double-faced symmetric locking groove structure and the double-layer rotary sliding block is provide with two symmetric locking buckles that are connected with the locking groove, thus ensuring the forward alignment code and the drawer front panel are stably to be fixed on the drawer side panel.

Spiral hole milling device

The invention discloses a spiral hole milling device. The spiral hole milling device comprises an rotationsystem, a revolution system, a feeding system and an eccentricity adjusting system. An electric main shaft in the rotation system drives a milling cutter to rotate through a spring collet arranged on an output shaft of the electric main shaft. A revolution motor in the revolution system drives an inner sleeve to perform revolution relative to the axis of an outer sleeve through a small synchronous pulley, a synchronous belt and a large synchronous pulley. A feeding motor in the feeding system drives a feeding lead screw to enable a feeding nut to move so as to achieve feeding. An eccentricity adjusting mechanism in the eccentricity adjusting system controls motion of a shifting sliding block, a fixed anti-backlash nut and a movable anti-backlash nut remove the backlash of the eccentricity adjusting system, and therefore high-precision adjustment of the eccentricity can be achieved. A holding mechanism arranged on the inner sleeve achieves the aim that the shifting sliding block is held on the inner sleeve after the eccentricity adjustment is completed. The spiral hole milling device can be applied to integral, high-quality and high-efficiency hole forming of difficultly-machined materials in the aerospace field.

Ink droplet border aligning optimizing method for nano silver inkjet printing and printer

The invention belongs to the technical field of inkjet printing micro-manufacturing, and discloses an ink droplet border aligning optimizing method for nano silver inkjet printing and a printer. The ink droplet boarder aligning optimizing method includes the steps that a relationship equation of the negative pressure and the ink droplet distance is obtained by fitting according to measuring the relationship between negative pressure values of different piezoelectric nozzles and the radius of a jetted nano silver ink droplet; a to-be-printed part in a printing model of the model surface is determined in a computer, and the to-be-printed part is separated and stored in a STL format; a beginning printing start coordinate and the printing interval length are calculated according to a G code provided with a jet interval command, the ink droplet radius supplementation is conducted on the printing length according to the radius of the ink droplet, and the ink droplet radius is stored in printing length variable values; the ink droplet distance in the printing process is determined according to the optimized printing length and the ink droplet radius, and the ink droplet falling point initial planning is conducted; a conductive figure surface is printed; and execution of all execution codes is completed, and a conductive figure is obtained. According to different base materials, the negative pressure is adjusted so as to change the size of the ink droplet to adapt to the base materials, and thus the uniformity of the border of the conductive figure is improved effectively.
