Apparatus for adusting position of a machining unit on a chip carrier maker

In a device for adjusting the position of a machining unit on a chip carrier making apparatus, the machining unit machining a tape consisting of a row of interconnected chip carriers which are integrally formed with each other, the apparatus including a stationary machine frame, and the device including a longitudinal adjustment unit capable of moving the machining unit in a direction parallel to the tape, and a transverse adjustment unit capable of moving the machining unit in a direction perpendicular to the tape, the improvement wherein said device comprises:

• two parallel sliding rails fixed on the machine frame and extending in a direction parallel to the tape;
• and
• a receiving seat mounted slidably on said sliding rails so as to guide said receiving seat to slide along the sliding rails when the longitudinal adjustment unit is actuated, said receiving seat having a top surface formed with a slide slot which extends in a direction perpendicular to the tape and which receives slidably the machining unit so as to guide the machining unit to slide along the slide slot when the transverse adjustment unit is actuated;
• wherein said transverse adjustment unit includes:
• a movable support plate disposed slidably within said slide slot of said receiving seat and carrying the machining unit on said movable support plate;
• a fixed support plate fixed on said receiving seat;
• a first fixing block fixed on said fixed support plate;
• a second fixing block fixed on said movable support plate and having a threaded hole formed through said second fixing block;
• two parallel guide rods extending through said first and second fixing blocks;
• two coiled compression springs respectively sleeved on said guide rods between said first and second fixing blocks;
• and
• an adjustment bolt journalled on said fixed support plate and extending threadedly through said threaded hole of said second fixing block so that rotation of said adjustment bolt on said fixed support plate will move said movable support plate and said machining unit along said slide slot of said receiving seat.
