This machine tool is a double column vertical lathe, in which the left and right tool rest are programmed tool rest.
The machine consists of gantry frame, working table, gearbox, beam, vertical tool rest, electrical, hydraulic station and other main parts.
The left column, right column, connecting beam, workbench, etc. form a closed symmetrical frame. The cross beam is driven by the lifting motor, reduction box, and screw, and moves up and down on the column guide rail. The main drive of the workbench is driven by a 75Kw motor and is reduced through gears so that the workbench can obtain the corresponding working speed. The gearbox has reliable performance.
The machine is suitable for rough and finish machining of black, non-ferrous metal and part of non-metallic parts with high speed steel and hard alloy cutters. it can process inner and outer cylindrical surface, end face, inner and outer conical surface, grooving.
Main transmission mechanism
The main transmission is driven by alternating current motor, the brake is energy consumption brake, with mechanical speed change, to achieve the required speed of the worktable. Variable speed is through the hydraulic cylinder push the fork to drive the gear to move to achieve. The power of the main drive motor is 75Kw, and the gearbox adopts high-precision grinding gears with low noise.
Feeding mechanism
The feed of the machine is divided into horizontal feed and vertical feed.
4.3. Gantry frame
The gantry frame is composed of left column, right column, middle beam, etc. The gantry frame is connected with the foundation to form a closed symmetrical frame. The high strength and low stress cast iron is used, which has enough stiffness and strength to ensure the accuracy of the machine has long-term retention and stability. Through finite element analysis and calculation, the gantry frame size structure and stress state reach the best, to ensure its sufficient strength and stiffness. In the upper part of the column is equipped with a lifting box, driven by a biaxial AC motor, by helical gear, worm gear, lead screw pair transmission, so that the beam on the column for vertical movement.
The workbench
The working table adopts static pressure guide rail, which is inlaid with zinc alloy guide rail plate, and is supplied with oil by synchronous shunt motor at constant current. It has the characteristics of stable static pressure, large load-bearing capacity and high precision. The spindle is equipped with high precision double row short cylindrical roller bearings to ensure the radial runout of the worktable. Working table speed range 0.5-40r
/min.
Table equipped with four jaw manual chuck.
Cross beam
The beam is placed in front of the column, driven by a biaxial extension AC motor, driven by gear, worm gear and screw pair, so that the beam can make vertical movement on the column. There are 4 hydraulic clamping points behind the beam. The sliding surface of beam and column is treated with wear-resistant soft belt.
Vertical tool rest
Tool rest is program-controlled tool rest, horizontal and vertical movement are driven by servo motor, stepless speed regulation and equipped with fast function, at the same time, machining feed 0.1-500mm/min, fast moving speed of tool rest 2000mm/min. Vertical tool rest adopts square ram structure.
The horizontal and vertical movement of the left and right tool rest adopt sliding plastic guide rail, which has the characteristics of wear resistance and long accuracy.
The tool rest is equipped with a hydraulic balancing cylinder to balance the weight of the ram.
Hydraulic system
The machine is equipped with independent hydraulic station, installation, repair, maintenance is particularly convenient. The hydraulic station is equipped with coarse and fine filter device; A pressure switch is arranged on the static pressure pipeline. When the static pressure pipeline loses pressure, the system will automatically alarm and stop. Only after troubleshooting can the worktable be started. The hydraulic station and the machine tool are connected by special soft connecting pipe (high pressure steel wire braided pipe).
The hydraulic box has enough capacity to ensure that the temperature of the hydraulic system is stable without affecting the precision of the bed.
Electrical system
The electrical cabinet of the machine tool is IP54 protection grade; Independent removable button station, easy to operate; adopts famous brand high reliability electrical components.
