The design of the motor and the reducer for the feed power section is selected from 1200 to 1500 mm/min. The old lead screw replaced by other machine tools has a pitch of 10 mm. The feed power source is BWY15- 11-2.2kW cycloidal pinwheel reducer, the reduction ratio is 1:11, the motor speed is 1470r/min, the actual speed of the carriage is 1336mm/min. After calculation, the motor power is 2.2kW, and there is a certain Power margin. The feed rate of the gearbox is 20mm/min. Considering the feed speed and the rigidity of the machine tool, the guide rail positioning type and the spindle speed, the feed frequency control method is adopted. The working characteristic of the ordinary frequency converter is that the power is also reduced when the speed is reduced, which is not suitable for the high power when the machine speed is high and the power is high when the speed is low. The frequency converter adopts Schneider's flux vector control frequency converter. The frequency converter is characterized by high torque output at low speed, that is, close to constant power output. It is suitable for this machine tool to require two different speeds to work. This is common. The inverter can not be realized, through which the transmission can be controlled to make the carriage movement fast and automatic. Encoder and counting device are used to realize the automatic function. We install the pulse encoder and counter. The encoder mounted on the lead screw sends out the pulse, and the counter counts the control motor to run as required, that is, it is automatically executed according to the set automatic program. Control: Workpiece fixing - manual drilling (the position of the first hole requires manual tool setting) - Stop - Milling the waist hole to the specified length - Waiting (manual retraction) - Travel to the starting position of the next waist hole - Stop (manual drilling), and some irregular workpieces can be manually completed. The design of the bed and the design of the bed is modified with the discarded C620-1 lathe bed. Since there is no guide rail in the head section, the head part needs to be shaved off, and then the screws, positioning pins and bonding are used. The cast iron plate is formed by planing by rail type, and then the guide rail is refined and surface hardened to achieve higher precision and long service life. The design of the carriage is made of cast iron. Considering that the carriage is too wide to affect the carriage stroke, the carriage is too narrow and the positioning is not good. We take the intermediate value of 350mm and use two pressure plates and one strip to position it. Stability and design of the felt felt plate to block the entry of dust and iron filings. The design of the rest of the mechanical device is used to ensure accurate transmission and avoid vibration. The threaded wire mother of the adjustable gap can be used for compensation. Therefore, the machine has high machining precision and is suitable for CNC automatic machining. . Conclusion The waist-shaped hole milling machine has withstood the test in the practice of the factory, can complete the production task with quality and quantity, relieve the burden of 125 é•— bed, avoid the damage caused by the high load of 125 é•— bed equipment, and no longer affect other products. The normal processing meets the requirements of the workshop manufacturing cycle, which solves a difficult problem for the company. (Finish)
