3results about How to "Control drilling depth" patented technology

The invention discloses an inclined secondary structure embedded steel bar construction method which comprises the following steps: S1, designing and optimizing an embedded steel bar point position and depth by using software; s2, a drilling machine is used for forming holes in the steel bar planting point positions in an inclined mode; s3, hole cleaning and glue injection; s4, the front ends of the steel bars are sleeved with fixing pieces, and steel bar planting is completed; s5, nondestructive anti-drawing force detection is carried out; a detachable angle control piece is used for standardizing the drilling angle, and a downward inclined hole forming mode is selected, so that the interior of a hole is cleaned conveniently; the angle control assembly capable of sliding on the machine body fixing piece can effectively control the drilling depth to avoid the situation that the drilling depth is too deep or too short; the embedded steel bar anchoring effect and the qualified rate can be greatly improved by matching with a fixing piece; and the torque sensor can cut off a power supply to prevent internal steel bars from being damaged when sensing reverse torque change.

The utility model discloses a kind of machining depth controllable magnetic base drill, including magnetic base;Magnetic base top end is fixedly connected with support frame, support frame one end is equipped with drill body;Support frame includes support arm, sliding block is slidably arranged between two support arms, sliding block one end is equipped with gear slot, meshing is carried out through gear slot and gear shaft fixedly connected on rotating shaft, rotating shaft is fixedly connected with rotating handle at one end of support arm penetration;It also includes limiting component, and limiting component is located on support frame, and the movement distance of drill body is preset through limiting component;In the utility model, rotating handle is driven rotating shaft and gear shaft fixedly connected with it to rotate by manual rotation, gear slot meshing of gear shaft is set on sliding block, so that sliding block drives directional movement of drill body under the transmission of rotating handle to complete drill body drilling, limiting component located on support frame is used to limit the distance of directional movement of drill body, realize that the equipment can control drilling depth according to actual demand.

This utility model belongs to the field of needle chuck processing technology, and in particular to a sewing machine needle chuck table drilling and feeding device. It includes a base with two sliding grooves on the top. Lower electric slides are slidably fitted within these grooves. A worktable is fixedly connected to the top of the two lower electric slides. A sewing machine needle chuck is placed on the top of the worktable. A clamping mechanism is provided between the needle chuck and the worktable. Two support plates are fixedly connected to the top of the base. This utility model has a reasonable structural design. Through a high-precision displacement sensor, the distance the drill bit or threaded drill rod moves downward can be measured, allowing for precise control of the drilling feed and thus precise control of the drilling depth. Furthermore, the drill bit and threaded drill rod are easily interchangeable, enabling the processing of both normal holes and internal threaded holes. It also facilitates the disassembly and replacement of drill bits and threaded drill rods of different diameters to drill normal holes and internal threaded holes of varying sizes.
