The invention discloses a cutter collision preventing method for a machining center. A plurality of measures are adopted, and methods for preventing cutter collision of the machining center are listed completely from three aspects, namely procedure improvement, misoperation avoidance and cutter compensation verification, and a solution method is proposed. The cutter collision preventing method is capable of effectively preventing cutter collision for the machining center by use of certain programming skills, and by verifying the procedure by use of various methods and avoiding misoperation by virtue of correct coordinate system and cutter length compensation and radius compensation settings and combined use of hands and eyes in the operation process, and therefore, the service life of the machining center can be increased and the repair cost can be saved.

The invention discloses an intelligent underwater hull cleaning robot, which includes a body, a driving mechanism, a cleaning device and a buoyancy adjustment mechanism. The outer side of the body is arranged in an annular array with no less than three sets of wings, and the ends of the wings are A driving mechanism is provided on the upper part of the body, a rotating cleaning mechanism is arranged in the middle of the body, and a buoyancy adjustment mechanism is arranged inside the body; Perpendicular to the machine body, the upper end of the installation cylinder is closed, and a plurality of through holes are provided on the circumferential wall of the cylinder of the installation cylinder, and a water disturbing plate is installed at each of the through holes, and the bottom of the installation cylinder is turned outward. A plurality of penetrating installation grooves are arranged on the flange, and scraper blades are installed in each of the installation grooves. This intelligent underwater hull cleaning robot can rinse the scraper blades during cleaning operations, and can remove the scraper blades during non-cleaning operations. The scraper knife is hidden.

The invention relates to the technical field of glass processing machinery, belongs to a glass drilling processing machine, and particularly relates to an electric control feeding mechanism of a drilling motor of a vertical glass drilling machine. The electric control feeding mechanism of the drilling motor of the vertical glass drilling machine comprises a base, a glass supporting frame and an upright post, wherein the upright post is provided with the drilling motor; a horizontal shifting module is arranged between the drilling motor and the upright post; a drilling bit port of the drillingmotor is provided with a clamping plate; the clamping plate is provided with a drilling bit feeding position inductive switch; a servo motor for driving the driving motor to advance and retreat is also arranged between the drilling motor and the horizontal shifting module; and the inductive switch and the servo motor are connected with each other and controlled by a numerical control system. The electric control feeding mechanism of the drilling motor of the vertical glass drilling machine has the following advantages that: 1, due to the adoption of the servo motor and a speed reducer, the drilling precision is improved; and 2, the inductive switch is used to implement the simultaneous working of a front drilling bit and a back drilling bit, the drilling bit at one side is fed to a certain preset position and then is stopped and dropped back, and the drilling bit at the other side is fed continuously, so the working efficiency is high, and cutter crash appearing in double-side feedingis avoided.

The invention discloses a double-spindle core-moving type numerical control lathe, the structure of which comprises a main machine of the lathe, a movable door, a window, a control panel, a fixed base, and a chip discharge pipe. A movable door is arranged at the front end of the main machine of the lathe, and a The waste chips enter the inside of the chip guide grooves on both sides, the toggle lever on the right turns clockwise, and the toggle lever on the left turns counterclockwise to ensure that the long strips of waste chips inside the chip guide grooves on both sides The chips are moved from top to bottom, and the hook plate can cut off the long strips of waste to prevent the collision between the workpiece and the tool. The shielding horizontal plate initially blocks the long strips of waste, and when the toggle lever is rotated, the spring is automatically reset after the toggle lever is rotated to separate from the plate body, so that the opening and closing plate is closed between the shielding horizontal plates , to prevent long strips of waste from entering the interior of the fixed frame, and ensure that the toggle lever can effectively dial down the waste.

The invention provides a connecting method for thin-wall shells. The connecting method for the thin-wall shells is used for achieving connection between the two thin-wall shells, the connecting ends of the thin-wall shells are cylinders, and the diameters of the thin-wall shells are the same. According to the connecting method for the thin-wall shells, the end of one thin-wall shell is subjected to spinning necking or flaring and trimming and then is matched with the other thin-wall shell; and then manners of welding and the like are adopted for connection. The connecting method has the beneficial effects that the spinning necking or flaring method is adopted, the technology is simple, and operation is easy; trimming is conducted after spinning necking or flaring, secondary positioning is not needed, the machining safety coefficients are high, and the service life of a tool is long; the thin-wall shells obtained after spinning necking or flaring are high in size precision, easy to match and high in connecting strength.
