Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hand tools, in particular to a drilling device. Background Art
[0002] At present, the drilling device used on the machine tools in the company's workshop is a power head servo motor located at the bottom of the equipment, which drives the ball screw and then drives the drill bit to perform radial movement. However, during use, it was found that this device has great disadvantages. Since the servo motor is at the bottom, when processing the workpiece, the cutting fluid is easy to splash onto the servo motor, causing the servo motor to burn out; due to the large cutting volume of the machine tool, when processing the workpiece, there is a lever force between the ball screw and the drill rod on the machine tool. Long-term use will cause the steel balls of the ball screw to break and fall off, making the ball screw scrapped and unusable. The above two situations have caused a serious increase in the cost of the processing process and increased the frequency and difficulty of maintenance and replacement by maintenance personnel. Utility Model Content

The motor fixing plate is used to fix the servo motor, and the whole is fixedly connected to the upper fixing frame. The upper end of the trapezoidal lead screw passes through the upper fixing frame, is connected to the servo motor through a coupling, and the lower end is locked with a locking nut. The copper nut 1 is screwed on the trapezoidal lead screw with the thick end facing upward, and the copper nut 2 is screwed on the trapezoidal lead screw with the thick end facing downward. The copper nut 1 and the copper nut 2 are the same workpiece, divided into a thick end and a thin end. The thick end is provided with a symmetrical arc-shaped long groove, and a trapezoidal threaded through hole is provided in the middle of the whole. The copper sleeve seat is movably connected to copper nut 1 and copper nut 2 by screws respectively. The thin end of copper nut 1 is embedded in the top of the copper sleeve seat, and the thin end of copper nut 2 is embedded in the bottom of the copper sleeve seat. Four through holes 1 are distributed on the base of the fixed seat 1, and through hole 2 is provided on the side. A threaded through hole is provided on the upper end of through hole 2. The screw is inserted into through hole 1 to fix the fixed seat 1 to the left and right sides of the copper sleeve seat. The guide column is a cylindrical rod of a certain length, and its upper end is inserted into through hole 2. The adjustment screw is screwed into the threaded through hole and adjusts the position of the guide column. Four through holes 1 are distributed on the base of the fixed seat 2, and through hole 3 is provided on the side. A threaded through hole is provided on the upper end of through hole 3. The fixed seat 2 is installed on the left and right sides of the lower fixing frame by screws. The copper sleeve is fixedly connected in through hole 3, and the lower end of the guide column is inserted into the copper sleeve hole and can move freely along its radial direction. When the machine tool is working, the servo motor drives the trapezoidal screw to rotate through the coupling, and then drives the copper nut 1, fixed seat 1, adjustment screw, copper sleeve seat, copper nut 2, and guide column on the trapezoidal screw to move up and down, and then drives the machine tool drilling power head to move up and down to complete the drilling process. When the machine tool runs for too long, a gap will be generated between the copper nut and the trapezoidal screw, which can be adjusted by screwing the copper nut 1 and copper nut 2, thereby increasing the service life of the drilling device.
[0005] The positive effects of the utility model are: a drilling device with reasonable structure, easy manufacturing and assembly of parts, which can greatly reduce the workload of maintenance personnel, increase the service life of the overall equipment, improve work efficiency, and reduce the cost of processing procedures.
