This process is very cumbersome.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the problems and designing a locking device of a power head of a drilling machine, which comprises a first power head fixing seat, a second power head fixing seat, a power head shell, a locking shaft, a locking sleeve, a locking retainer ring, a locking screw, a turnover pin shaft, a locking pressing plate and a locking wrench; the locking mechanism comprises a first power head fixing seat, a second power head fixing seat, a locking sleeve, a locking screw, a locking retaining ring, a locking pressing plate and a locking screw rod, wherein one end of the first power head fixing seat, one end of the second power head fixing seat and one end of the power head shell are connected through a turnover pin shaft; the locking sleeve is fixedly connected with the locking retainer ring.
In order to further supplement the technical scheme, the locking wrench moves up and down to drive the locking sleeve and the locking check ring to reciprocate around the locking shaft, the locking sleeve and the locking screw are tangent to each other in an eccentric circle, and the locking screw reciprocates in a tangent contact motion in the eccentric circle.
In order to further supplement the technical scheme, the first power head fixing seat and the second power head fixing seat are arranged in parallel on the same horizontal plane.
In order to further supplement the technical scheme, the locking screw penetrates through the locking pressing plate and is spirally fixed through the hexagonal nut, so that the power head of the drilling machine is locked.
In order to further supplement the technical scheme, an elastic washer is arranged between the locking screw and the locking pressure plate for buffering.
Has the advantages that:
1. the lever principle of the locking wrench is utilized to increase the stress contact between the workpiece and the workpiece, so that the aim of concise locking is fulfilled;
2. the power head can be freely turned over by movably locking or loosening the power head up and down through the wrench, and the connection is safe and reliable;
3. the power head of the drilling machine is convenient to disassemble and assemble, the whole process is very simple and convenient, and time and labor are saved.
