Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the present invention comprises a driving mechanism 1, a base 2, a universal joint 3, a push rod device, and a positioning device. The driving mechanism 1 is internally provided with a motor.
The ejector rod device comprises a steel rod groove 4 and an ejector rod 5, the steel rod groove 4 is formed in the upper surface of the base, and the ejector rod 5 is connected with the output end of the motor and arranged above the steel rod groove. When the positioning device works, the motor drives the ejector rod to eject the steel rod placed in the steel rod groove into the positioning device.
The positioning device comprises a positioning frame 6, two roll shafts 7 and two pressing plates 8, wherein the roll shafts 7 are connected with the output end of the motor through universal joints 3 and are respectively arranged on two sides of the steel bar groove 4, the pressing plates 8 are respectively arranged on the upper side and the lower side of the positioning frame 6 and are matched with the roll shafts 7 to form positioning holes in the positioning frame 6. Two roller 7 and two clamp plates 8 are accurate definite with the steel rod and are located in the locating hole, motor drive roller rotates simultaneously, and the roller drives the steel rod and rotates when drilling, has greatly reduced the production of vibration when the steel rod is drilled, has guaranteed going on smoothly of drilling.
The top of the base is also provided with a gear type tightness adjusting device 9 for adjusting the up-and-down pressing or loosening of the pressing plate 8. The roller 7 is fixed in through fixed disk 10 on the locating rack 6, just the fixed disk 10 with the locating rack passes through hexagon screw and connects, is convenient for adjust being close to or part of roller. The gear type tightness adjusting device 9 and the hexagon screws are arranged, so that the positioning device can adapt to steel rods of different models. The pressing surface of the pressing plate 8 close to the positioning hole is an arc-shaped concave surface, so that the positioning is more accurate and quicker, and the smoothness of the rotation of the steel rod is also ensured. The part of the roll shaft 7 between the universal joint and the positioning device is provided with a protective pipe to prevent external sundries from entering and influencing the normal operation of the roll shaft.
The groove surface of the steel rod groove 4 is formed by splicing two steel plates, the two steel plates are downwards inclined at the splicing part, and a plurality of holes are uniformly formed in the steel plates.
