Description

Reaming device

Technical Field

The utility model relates to a reaming device.

Background

The connector is generally divided into two parts, a male part provided with a cylindrical insertion pin and a female part provided with a tubular insertion tube, the male part being inserted into the female part in use so that the cylindrical insertion pin is inserted into the tubular insertion tube. The common tubular insertion tube is provided with a jack distributed along the central line of the tubular insertion tube and a transverse hole which is distributed perpendicular to the jack and penetrates through the tubular insertion tube, wherein the jack is used for accommodating a columnar insertion pin, and the transverse hole is used for being connected with a lead. The length of the tubular cannula is at most ten millimeters, and the diameter of the tubular cannula is at most two millimeters and three millimeters, so that the tubular cannula is very small in volume and belongs to a precise device.

In the prior art, a tubular insertion tube is reamed manually. The whole reaming process comprises four steps: firstly, a worker drills jacks by using a manual drill, the drill moves along the central line of the cylindrical metal thin strip, enters from one end of the cylindrical metal thin strip and then drills out from the other end of the cylindrical metal thin strip, and the jacks are formed at the central line of the cylindrical metal thin strip; secondly, another group of workers drill a transverse hole by using another manual drill, the drill moves in the direction vertical to the central line of the cylindrical metal thin strip, enters from one side of the cylindrical metal thin strip and then drills from the other side of the cylindrical metal thin strip, so that a transverse hole which is vertical to the insertion hole and is in rubber connection with the insertion hole is obtained on the cylindrical metal thin strip, and burrs are generated in the original insertion hole area when the drill processes the transverse hole; thirdly, the other batch of workers use a manual drill to stretch into the jack, and burrs in the jack are removed through high-speed movement of the drill; and fourthly, in order to eliminate the burrs which are originally positioned in the jack and are collided by the drill bit to enter the transverse hole, the other batch of workers stretch into the transverse hole by using a manual drill bit, and the burrs positioned in the transverse hole are removed by the high-speed movement of the drill bit. In actual production, the four steps are carried out one by four groups of workers, namely, one group of workers are responsible for drilling the jack, one group of workers are responsible for drilling the transverse hole, one group of workers are responsible for removing burrs in the jack, and the other group of workers are responsible for removing the burrs in the transverse hole, so that the line production is realized.

The manual reaming operation has low working efficiency and low quality stability, and the main reason is that each of the four steps needs a new positioning operation before being implemented, and if the positioning operations are different, the processing precision of the jacks and the transverse holes is easily influenced, and the phenomena of position deviation and large aperture are generated.
