Mechanical and hydraulic rocker drills

Mechanical rocker drill: it adopts mechanical pre-selected speed change mechanism, which can save auxiliary time. The main shaft positive and negative rotation, parking, variable speed, neutral and other movements, with a handle control, manipulation of portable headstock, rocker arm, inner and outer column using hydraulic driven diamond block clamping mechanism, reliable clamping rocker arm guide rail, spindle sleeve and inner and outer column rotary raceway are quenched, can extend the service life. The headstock can be moved by hand and maneuvering.

Hydraulic rocker drill: it adopts hydraulic preselected speed shifting mechanism, which can save auxiliary time. Spindle positive and negative rotation, parking, shifting, neutral and other movements, with a handle control, easy to operate. Rocker arm guide rail, outer column round surface, spindle, spindle sleeve and inner and outer column rotary raceway are all quenched, which can maintain the stability of rocker arm drill accuracy for a long time and prolong the service life. In the structural design and manufacturing process of hydraulic rocker drill, a series of effective measures have been taken to greatly extend the precision and durability of the machine tool and the service life of the whole machine. It has perfect safety protection device and outer column protection. The spindle box, rocker arm and inner and outer column adopt hydraulic driven diamond block clamping mechanism, clamping reliable.

1. The locking mechanism of the rocker arm is different. Mechanical rocker arm is controlled by mechanical control of rocker arm lock, hydraulic rocker arm is controlled by hydraulic control to lock rocker arm.

2, drilling machine refers to the main use of drill bits in the workpiece hole processing machine. Generally, the main movement of the bit is rotation, and the axial movement of the bit is feed movement. The drilling machine has the advantages of simple structure and relatively low machining precision. It can drill through holes, blind holes, replace special tools, reaming, countersinking, reaming or tapping. The workpiece does not move in the process of processing, let the tool move, the tool center to the center of the hole, and make the tool rotation (main movement). The characteristic of the drilling press is that the workpiece is fixed, the tool is rotated and fed along the principal axis. The operation can be manual or motor.

Mechanical rocker drill speed is driven by gearbox speed spindle, hydraulic rocker drill is driven by a motor hydraulic pump through the hydraulic loop drive spindle, than the general mechanical rocker drill power transmission is large and more accurate.
