Elevator Guide Rail CNC Drilling Machine Main Structure and Technical Features
This machine tool is composed of drilling head spindle part, column part, cross carriage part, bed part, fixture part, cooling system, lubrication system, cooling system, operating system, electrical control and other main parts.
1、Main shaft parts of drill head
The variable-speed spindle motor drives the timing pulley, which in turn drives the spindle to rotate. The machine tool spindle adopts Taiwan imported thinking brand standard spindle, which has high rotation precision and low maintenance rate. Spindle speed can be adjusted freely, max. speed can up to 1500r/min.
The upper guide rail of column components adopts Taiwan Shangyin brand linear guide rail, which has high wear resistance and high precision. The column is equipped with a hydraulic cylinder to balance the drilling head components, and the accumulator balance principle is used for balance.
3、cross carriage parts
The carriage parts made of high-quality casting materials realize the front and back and left and right movement of the column. The form of the guide rail on the carriage is the straight guide rail of Taiwan Shangyin brand, which ensures the position accuracy of the movement. The carriage movement is driven by servo motor and ball screw. The rated power and torque of servo motor are 2.3KW and 15N / m respectively.
Fixture parts, column parts, etc. are installed on the same bed base, which increases the overall rigidity. The bed parts are equipped with chip removal cooling system. Necessary protective covers are designed on the bed to protect the operation safety and make the machine more beautiful.
The fixture is installed on the bed. The fixture is clamped up and down, left and right by two hydraulic cylinders. The clamping pressure is generally 3Mpa. The clamping principle is as follows:
(1) the left and right clamping cylinders clamp the guide rail with relative low pressure first, and then centralize the guide rail;
(2) the upper and lower clamping cylinders press the guide rail with high pressure;
(3) the left and right cylinders pressurize, so that the left and right cylinders clamp the guide rail with high pressure. Clamping the guide rail in these steps can make the guide rail fit the datum plane to the greatest extent, so as to eliminate the clamping error.
Each guide rail of the machine tool is equipped with an automatic lubrication system, so as to improve the service life of the guide rail and maintain the working accuracy of the machine tool for a long time. When there is a problem in the lubrication of the machine tool, the machine tool will automatically alarm. The fixture is lubricated by the manual lubrication pump under the operation box.
In order to prevent the guide rail from deforming due to overheating and reduce the tool wear, the machine tool is equipped with a cooling system. The cooling water solution containing 5-10% emulsified oil is driven by a three-phase electric pump in the water tank, and then the guide rail in the process is continuously cooled by the cooling pipe. The flow can be adjusted by the valve on the metal hose, and the cooling water flowing down the machine bed And then flow back to the water tank to form a recycling use.
8、 hydraulic system
The machine is equipped with hydraulic station and manufactured by domestic famous manufacturers. The hydraulic pipes inside the machine tool are all hard pipes, and the external part of the machine tool is connected to the hydraulic station with hoses.
9、 operating system
Elevator Guide Rail CNC Drilling Machine is equipped with an independent operation button station, which is distributed beside the station. The button station is equipped with various operation buttons and emergency stop buttons that can control the machine tool, as well as the operation key board and display screen of the CNC system. CNC system is a Guangzhou CNC brand, and the main low-voltage electrical components are German Schneider brand.
