The complete use steps and working principle of the above embodiment are as follows:
firstly, when a worker uses the device to drill a workpiece, the worker can firstly place the workpiece to be drilled on the upper surface of the drilling platform 14, and can clamp and position the workpiece through at least three fixed cylinders 15 so as to ensure the stability of the workpiece on the upper surface of the drilling platform 14, thereby being beneficial to the drilling work;
then, the worker can operate the device to make the drill bit 13 installed below the left side of the main shaft driving box 11 move downwards gradually, and in the process of moving downwards synchronously with the drill bit 13 and the water jacket 12 installed above the drill bit 13, because the outer wall of the rear side of the main shaft driving box 11 is hinged with the movable bar 21, the lower end of the movable bar 21 is hinged with the cross shaft 22, the middle part of the cross shaft 22 is rotatably connected with the central bar 23, and the upper end of the central bar 23 is hinged with the outer wall of the rear side of the water jacket 12, when the water jacket 12 and the drill bit 13 move downwards, the distance between the central bar 23 and the cross shaft 22 in the initial state is shortened, and the central bar 23 pushes the cross shaft 22 and the movable bar 21 to rotate by taking the hinged point of the upper end of the movable bar 21 as a rotation fulcrum, and after the cross shaft 22 moves, because the side bars 24 are fixedly connected on the surface of the cross shaft 22 and at the left and right sides of the central bar 23, therefore, the side lever 24 can drive the protective sleeve 25 to move synchronously, and because the protective sleeve 25 is positioned at the left side and the right side of the drill bit 13, the inner wall of the protective sleeve 25 is provided with the brush hair, and the brush hair at the inner wall of the protective sleeve 25 is attached to the outer wall of the drill bit 13, the brush hair can be driven to clean once along the outer wall of the drill bit 13 after the protective sleeve 25 moves, so that the cleaning work of most of the cuttings remained in the blade groove can be automatically completed along with the downward movement of the drill bit 13, thereby improving the condition that the drilling precision is influenced due to excessive accumulation of the cuttings in the blade groove of the drill bit 13, simultaneously, the protective sleeve 25 does not need to manually contact the drill bit 13 in the cleaning process and does not need to use external force as a driving source, thereby not only saving manpower, but also reducing the energy consumption of the device, in addition, because the protective sleeve 25 is in a semicircular shape, the initial state of the protective sleeve 25 covers most of the area of the outer wall of the drill bit 13, so that the drill bit 13 can be protected to a certain extent under the shielding effect of the protective sleeve 25, and the condition that workers touch the surface of the drill bit 13 accidentally to cause injury can be reduced;
meanwhile, when the movable strip 21 rotates with the hinge point at the upper end of the movable strip 21 as the rotation fulcrum, at this time, the lower end of the movable strip 21 is fixedly connected with the follow-up rope 31, the lower end of the follow-up rope 31 is wound on the outer wall of the rope winding shaft 32, the length of the part, wound on the outer wall of the rope winding shaft 32, of the lower end of the follow-up rope 31 is equal to one half of the circumference of the turntable 34, and one half of the circumference of the turntable 34 is equal to the horizontal length of the connecting curved rod 38, so that the lower end of the follow-up rope 31 is pulled to gradually separate from the outer wall of the rope winding shaft 32 under the rotation of the movable strip 21, the rope winding shaft 32 is rotatably connected to the bottom surface of the fixed frame 35, the rope winding shaft 32 rotates under the traction force of the follow-up rope 31, and after the follow-up rope 31 wound on the outer wall of the rope winding shaft 32 completely separates, the follow-up rope 31 can drive the turntable 34 to rotate by half a turn, when the rotary table 34 rotates, under the matching action of the lath 36 and the U-shaped ring 37, one end of the lath 36 close to the U-shaped ring 37 slides in the U-shaped ring 37, so that the connecting curved rod 38 horizontally slides under the limitation of the upper end of the fixing frame 35, when the rotary table 34 rotates half a turn, the connecting curved rod 38 is driven to horizontally move for the same distance, and then the protective cover 39 and the central hole 310 are driven by the connecting curved rod 38 to horizontally slide leftwards along the outer wall of the drilling platform 14 in the process of moving the drill bit 13 downwards, finally the position of the central hole 310 is just below the drill bit 13, at this time, the protective cover 39 covers most of the area above the workpiece, and the drill bit 13 can directly pass through the central hole 310 to drill the workpiece below, so that most of chips can be prevented from splashing under the shielding effect of the protective cover 39, and when the drill bit 13 is broken, in addition, the whole protective cover 39 is made of transparent visual sound insulation material, so that the workers can visually observe the real-time situation of the drilling work, and meanwhile, the noise generated in the drilling process can be reduced, and the environment of the drilling work is further improved;
on the contrary, after the drilling operation of the drill bit 13 is finished, the drill bit 13 is driven to move upwards along with the operation of the operator, the movable strip 21 is driven to reset after the drill bit 13 moves upwards, and the follow-up rope 31 is not subjected to the traction force of the movable strip 21 any more at this time, so that the lower end part of the follow-up rope 31 is driven to wind the outer wall of the rope winding shaft 32 again under the action of the rebounding force of the torsion spring shaft 33 by the follow-up rope 31, and the rotary disc 34 is driven to rotate and the protective cover 39 automatically resets at the same time;
in addition, because the elastic strip 41 and the push brush 42 are fixedly installed at the left side of the protection cover 39, in the process of moving the protection cover 39 to the left, the lower end of the push brush 42 contacts the upper surface of the workpiece, so that most of the impurities or dust on the surface of the workpiece can be swept away from the processing surface of the workpiece, and the drill bit 13 can better perform drilling, when the protection cover 39 drives the push brush 42 to move to the position of the convex ball plate 44 synchronously, because the spring balls 43 are fixedly connected to the outer walls of the front side and the rear side of the push brush 42, the convex ball plate 44 is arranged at the left side of the spring ball 43, and the convex ball plate 44 is fixedly connected to the upper surface of the drilling table 14, the surface of the convex ball plate 44 is uniformly provided with protrusions, the protrusions on the surface of the convex ball plate 44 and the spring balls 43 are on the same horizontal line, and one end of the spring ball 43 far away from the push brush 42 can be abutted against the protrusions on the surface of the convex ball plate 44, so that the protrusions on the surface of the convex ball plate 44 and the spring balls 43 are directly driven to vibrate, thereby effectively completing the dust sweeping.
