[0006] The transmission gear is meshed with the drive gear, the threaded rod is rotatably connected to the positioning plate, the telescopic shaft is rotatably connected to the positioning plate, the front gear is rotatably connected to the cylinder shaft plate, the sleeve shaft is rotatably connected to the cylinder shaft plate, the sleeve shaft is slidably connected to the spline rod shaft, the spline rod shaft is slidably connected to the rear gear, the transmission shaft is slidably connected to the through plate, the spline rod shaft rotates from the top surface of the drilling end to the bottom surface, the rear gear and the front gear are meshed and connected, and the motor and the hydraulic rod are controlled by the external terminal to be in a working state. When the hydraulic rod is in a retracted state, the hydraulic rod will drive the control motor to approach the mounting plate below, and the control motor will push the gear fixed plate to move through the output shaft, so that the gear fixed plate moves to drive the driving gear and the mating transmission tooth to move downward and rotate at the same time driven by the output shaft, and the driving When the gear is in full engagement with the gear, the threaded rod is driven to rotate by the rotation of the gear wheel, so that the sliding end outside the threaded rod moves downward away from the positioning plate and slides downward along the slide rail, so that the sliding end is moved downward toward the position where a hole needs to be drilled through the drilling end connected to the barrel plate, so that the drilling end can adjust the drilling depth through the structural lifting, thereby improving the flexibility of the drilling end structure. At the same time, the telescopic shaft is driven to rotate by the rotation of the cross rod, so that the spline rod shaft connected to the telescopic shaft rotates, and the connected rear gear drives the front gear to rotate through the rotation of the spline rod shaft, and then the connected transmission shaft is driven to rotate through the rotation of the front gear, so that the transmission shaft makes the drilling work inside the drilling end, and the rotation state of the threaded rod is controlled through the cooperation of the matching transmission teeth and the gear wheel.

[0007] The top end of the oil pump stretches out the cam frame, and the top end of the oil pump stretches out the cam frame, and the top end of the oil pump stretches out the cam frame, and the top end of the oil pump stretches out the cam frame, and the cam frame is fixedly connected to the oil pumping station.

[0008] According to the above technical solution, the shaft seat is fixedly connected to the through plate, a return spring is arranged on the outside of the vent pipe, and both ends of the return spring are fixedly connected to the oil tank and the pressure plate respectively.

[0009] According to the above technical scheme, the pipe head and the side convex block fit each other, the ventilation pipe is slidably connected to the oil lubricating tank, the oil receiving end is fixedly connected to the through plate, the sponge ring block and the spline rod shaft fit each other, and the extrusion wheel is fixedly connected to the transmission shaft. When the transmission shaft rotates, it will drive the connected convex block wheel to rotate. When the convex block wheel rotates one circle, the meshing gear is driven by the convex teeth to rotate a certain angle around the connection with the rotating shaft seat. When the meshing gear rotates to make the side convex block squeeze the pipe head, the pipe head will push the connected ventilation pipe to slide along the oil lubricating tank after being subjected to force, and the ventilation pipe will approach the plug along the inner side of the oil lubricating tank.

As the air between the plug and the pressure plate increases and the air pressure increases, the gas will push the plug to squeeze the internal space of the oil tank on the side away from the pressure plate. The lubricating fluid in the oil tank will enter the oil receiving end through the connected oil pipe by squeezing. The transmission shaft rotates to make the meshing gear drive the pressure plate to compress the air. The precision parts are automatically lubricated at long time intervals by compressed air, which reduces maintenance costs, reduces wear and increases the service life of precision parts.

By squeezing, the lubricating fluid in the oil lubricating tank 69 will enter through the connected oil delivery pipe 613 The air is then passed through the oil receiving end 614, and the transmission shaft 520 is rotated to make the meshing gear 63 drive the pressure plate 610 to compress the air. The compressed air is used to automatically lubricate the precision parts at long intervals, thereby reducing maintenance costs, reducing wear and prolonging the service life of the precision parts. At the same time, the transmission shaft 520 is rotated to drive the extrusion wheel 616 to rotate and squeeze the sponge ring block 615 in contact, so that the sponge ring block 615 squeezes out the lubricant absorbed inside and applies it to the outside of the spline shaft 511. The sponge ring block 615 squeezes and fits the side of the spline shaft 511 to improve the lubrication effect, and the lubricant at the squeezed position drips to the oil receiving end 614 for collection, so that the remaining lubricant in the oil receiving end 614 drips downward to the sliding position between the rear gear 514 and the spline shaft 511, so as to achieve re-lubrication and reduce the wear between the sliding structures, and the lubricant drips from the rear gear 514 and is collected in the oil retaining groove 617. When the threaded rod 57 rotates, the sliding end 512 moves downward along the slide rail 58, and the reciprocating plate 71 moves upward away from the sliding end 512 along the threaded rod 57. At this time, the upper hinge plate 72 connected to the reciprocating plate 71 and the lower hinge plate 73 connected to the through plate 518 are connected to each other, so that the connection between the upper hinge plate 72 and the lower hinge plate 73 is deflected, and the hinge block 74 connected to the connection between the upper hinge plate 72 and the lower hinge plate 73 pulls the hinge block vertical plate 75 to move, so that the hinge block vertical plate 75 moves and pushes the connected abutment plate 78 to move to the bottom of the drilling end 516. At this time, the sliding and retractable positioning slide plate 8 below the drilling end 516 passes through the abutment plate 78 and The connected abutment plate 78 contacts the processing table surface on the bottom surface, and then the push groove folding rod 76 sliding outside the hinge block vertical plate 75 moves together with the pressure groove 77 close to the side of the drilling end 516. The pressure groove 77 presses the top of the push groove folding rod 76 to make the push groove folding rod 76 push the connected pressure plate 79 downward to squeeze the spring sheet 711 on the bottom side, so that the elastic pressure plate 79 drives the connected rubber strip 710 to press the material to be drilled to prevent the material from being displaced during the drilling process and affecting the drilling quality. In addition, the drilling end 516 and the reciprocating plate 71 are used to move in the opposite direction, so that the connected abutment plate 78 can realize the function of automatically pushing and transferring materials.
