Embodiment Construction
[0026] refer to figure 1 , a motor-driven numerically controlled friction welding machine, including a frame 13, a moving fixture, a rotating fixture and a loosening link 1.
[0027] refer to figure 1 with figure 2 , the rotating fixture includes a spindle box 3, a hollow spindle 22 is axially pierced in the spindle box 3, and a pressure bar 23 is fixed inside the hollow spindle 22, and the spindle 22 protrudes from both ends of the spindle box 3, so The pressure rod 23 protrudes from both ends of the main shaft 22, and a series of disc springs 24 are placed on the pressure rod 23. The inner diameter of the initial section of the main shaft 22 is large, and the diameter of the tail section is small. The disc spring 24 on the pressure bar 23 is located on the main shaft 22 inner large-diameter sections, a snap ring 25 is fixedly sleeved on the depression bar 23, and the snap ring 25 compresses the disc spring 24 on the protrusion of the main shaft 22 inner sleeve by the wa...

The structure of motor driving numerically controlled friction-welding machine is indicated that chief axis with pressure lever in is in the chief axis box of machine frame, and there is spring at thepressure lever in the spacing terminal of chief axis and pressure lever, the pressure lever and chief axis end socket elastically adapted. The screw, lead screw and screw base are taken as mobile digging drive, the screw base is in the rack mounting trough, there is a sliding table trough used for the sliding table on the rack and a digging body of vertical direction on the sliding table, the right and left sliders are holed at the spring conductor bar of the digging body, the left slider is fixed while the right one can slide, a clamp splice is at the end part, there are springs at the spring conductor bar between the spacing terminal of the slider and the sidewall of the digging wall, the sidewall of the loose clip connecting rod corresponds with the pressure lever, the base is inter embed in the axial direction elongated slot of the sliding table, the pin lower extreme at the bottom of the right slider is situated at one side of the side bevel of the screw in the rack mounting trough by thrilling through the drilling body and sliding table, the side bevel of the screw base is axial direction perpendicular, the upper extreme of screw base convexes into the square trough on the vertical axial direction of the sliding table and can glide in the axial direction trough. The chief axis and lead screw connect with motor drive, which evades the oil leaking and noise.
Description
technical field [0001] The invention relates to a numerical control equipment for friction welding, especially a semi-automatic numerical control friction welding machine which has no hydraulic (or pneumatic, etc.) drive and only uses two servo motors to complete all program work. Background technique [0002] At present, the known continuous drive and inertia friction welding machine structure is composed of motor-driven spindle rotation, hydraulic or pneumatic drive slide table, hydraulic or manual mechanical fixture and PLC (or IPC) electronic control combination. The hydraulic pressure drives the movement of the sliding table to make the two welded workpieces contact, and the welding parameters are determined by adjusting the pressure of the hydraulic valve, setting the PLC time or the displacement of the grating ruler. For example: the pressure mechanism of the friction welding machine introduced in "Friction Welding" (Mechanical Industry Press 1983) edited by Ning Pei...
