Along the vertical plane in the front-back direction, the drill bit performs eccentric machining of deep holes in the axial direction on the cylindrical workpiece. When the eccentricity needs to be adjusted, the gasket between the mounting plate and the connecting plate can be increased or decreased.

The effect of the compression spring is: the pressing plate is always in contact with the compression nut, so that the pressing plate can not move backward along the guide rod and affect the placement of a cylindrical workpiece between the V-shaped mouth and the pressing plate.

In summary, the manual clamping eccentric deep hole drilling device has a simple structure, easy manipulation, convenient operation, and high degree of automation. It is specially used for drilling eccentric deep holes in cylindrical workpieces. It is easy to process, accurate in positioning, and practical. Strong, easy to popularize and apply.

Detailed ways

As shown in Figure 1 and Figure 2, the manual clamping type eccentric deep hole drilling device includes a base 1, on which a transmission screw 2 and two slide rails 3 are horizontally arranged along the front and rear directions, and the transmission screw 2 is located on the Between the two slide rails 3, a movable seat 4 is slidably connected on the slide rail 3, and the lower part of the movable seat 4 is threadedly connected with the transmission screw 2, and the rear part of the base 1 is provided with a drive motor 5 for driving the transmission screw 2 to rotate, and the movable seat 4. The front side is provided with a rotary motor 6 and a drill clamp 7 connected by transmission. The drill clamp 7 clamps a drill 27 arranged horizontally along the front and rear directions. Manual clamping mechanism and two positioning mechanisms on the plate 28, each positioning mechanism all comprises connecting plate 8 and positioning clamping block 9, and connecting plate 8 is fixedly connected on the mounting plate 28 by connecting bolt 10, and connecting plate 8 lower surface A flat keyway is correspondingly arranged between the upper surface of the mounting plate 28, and a positioning key 11 is arranged in the flat keyway. The upper surface of the connecting plate 8 is fixedly connected with the lower surface of the positioning clamping block 9 through the connecting block 24, and the upper surface of the connecting plate 8 is connected with the positioning key.
