The cost of reason, improves drilling efficiency.
2. described plate upper surface one end be equipped with it is leader fixed, along the leader fixed axial both sides at least provided with one
To the guide groove that is open, the adjustable range of centre-to-centre spacing is larger, the high precision machining of the bottom plate, while convenient for assembly and repair.
3. the briquetting side is pressed on the frame body, prevent the frame body from loosening influence processing essence in use
Degree.Seal face is inclined-plane, and contact area is larger, uniform force.
4. it is described it is leader fixed be that two pieces of insides set bevelled plate and V-shaped distribution, can be used for fixed difference
The guide rod of diameter, positioning is reliable, increases the scope of application of the tooling.
5. the jacking block upper end is fixed the jacking block upper end with guide rod front end by sliding block, it can meet and process radial direction
The verticality requirement of the center line in hole and guide rod axial line, positioning accuracy is high, and the machining accuracy of drilling is higher.The jacking block lower end
The open slot that is arranged and the jacking block sliding slot on the jacking block is passed through to be fixed on the bottom plate by bolt, it can be by adjusting
Relative position between the open slot and the jacking block sliding slot, to adjust the position of the jacking block, to meet different sizes
The processing request of structure guide rod also allows for the jacking block for dismounting different requirement on machining accuracy.
6. the center line of through-hole and leader fixed center line are perpendicular on the frame body, it can be accurately positioned drill bit, it is full
The verticality requirement of the processed radial hole of foot, ensures machining accuracy.The symmetrically arranged floor of the frame body upper cover plate and side rises
Certain supporting role prevents the frame body from deforming.
