Description

Magnetic Drilling Large Aperture Processing Device

technical field

The invention belongs to the technical field of magnetic drills, and in particular relates to a large-aperture processing device for magnetic drills.

Background technique

When installing large and medium-sized equipment in outdoor and high-altitude operations, the equipment with threaded connection needs to be drilled on the surface of the object to be installed in advance. The installation of some equipment requires precise drilling and tapping on the surface of the material like indoor machine tool drilling. , but general hand tools cannot achieve accurate drilling; secondly, when drilling and tapping vertical steel structures, and when inverted drilling and tapping are required, people need to consume a lot of physical strength to fix the drilling machine, or they cannot fix the drilling at all. Work practice urgently needs a tool: firstly, it is light in weight, which is very suitable for outdoor and high-altitude operations; secondly, when it starts drilling and tapping, it can be attached to the steel structure by itself, and it does not need to be fixed manually. The magnetic drill is a metal processing tool that can be adsorbed on the steel structure for drilling, tapping and reaming. It can well solve the problem of outdoor and some indoor drilling operations.

The existing magnetic drill equipment still has some problems, for example, it is difficult to achieve precise positioning during drilling, and the magnetic drill needs to be manually moved for positioning. When the magnetic drill is placed, it is troublesome to manually move the magnetic drill for positioning, but it is still feasible. When the magnetic drill needs to be used for upside-down drilling and tapping, it is extremely difficult to precisely locate the drilling position by manually moving the magnetic drill.

For hole reaming, especially when the diameter of hole reaming is large, large machine tools are generally required, and large drilling tools are used for processing. However, due to the requirement of convenience of use, the existing magnetic drill is generally designed with a larger volume. It is small and equipped with a small tool drive motor, so it does not have the ability to ream large holes.

In addition, the existing magnetic drilling equipment can only punch holes in the fixed plane where the equipment is located. When there is a certain angular deviation between the fixed plane and the position where the hole needs to be punched, the existing magnetic drilling equipment cannot punch holes, that is, the working range is limited. Sex is greater.

In summary, there is an urgent need for a magnetic drill capable of precise positioning and oblique angle drilling to solve the above problems.

SUMMARY OF THE INVENTION

At the same time, for the working conditions that require the use of a magnetic drill for hole reaming processing, the present invention uses the cooperation of the Z-axis moving device, the polar coordinate ρ direction moving mechanism and the polar coordinate θ direction moving mechanism to move along the hole in the hole reaming plane. The circular interpolation motion in the circumferential direction of the reaming hole and the feed motion along the Z axis (vertical to the circumferential direction of the hole to be reamed) are realized by reaming machining. This reaming machining method uses a small drive motor and a small drilling tool, and uses a drilling Or the method of cutting the side of the hole to be reamed by the milling tool, and realizing the large-diameter hole-reaming processing through circular interpolation, effectively solving the problem that the existing magnetic drill cannot perform the large-diameter hole-reaming processing.
