Description

Technical Field

[0001] This utility model relates to the field of drilling technology for non-ferromagnetic material round tubes, and in particular to a magnetic drill fixing structure for drilling non-ferromagnetic material round tubes. Background Technology

[0002] A magnetic drill is a device with an electromagnet at its base that generates magnetism when energized, allowing it to directly adhere to steel components for drilling. When energized, a magnetic drill can adhere to steel plates and structural parts, providing a secure hold and avoiding the drifting problem common with traditional drilling tools. However, magnetic drills cannot be directly fixed to non-ferromagnetic materials. Currently, there is no dedicated equipment on the market for drilling non-ferromagnetic round tubes. Therefore, using a magnetic drill to drill non-ferromagnetic round tubes remains an important method, and thus, the problem of fixing magnetic drills to non-ferromagnetic round tubes needs to be solved. Utility Model Content

[0003] This utility model provides a magnetic drill fixing structure for drilling holes in non-ferromagnetic material round tubes to solve the technical problems existing in the prior art. This structure can easily and securely fix the magnetic drill on the non-ferromagnetic material round tube.

[0004] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is: a magnetic drill fixing structure for drilling non-ferromagnetic material round tubes, including a fixing base plate made of ferromagnetic material, a magnetic seat limiting frame provided on one side of the fixing base plate, an arc-shaped clamping plate fixed to the fixing base plate and conforming to the round tube on one side below the fixing base plate, a pre-tightening plate conforming to the round tube on the other side, a pre-tightening bolt provided on the back of the pre-tightening plate and abutting it, and two nuts connected to the pre-tightening bolt, one of which is fixed to the back of the pre-tightening plate, and the other nut is connected to the fixing base plate through a support frame.

[0005] The upper end of the arc-shaped clamping plate extends to the lower middle part of the fixed base plate, and the lower end extends to the 8 o'clock position of the pipe section, adopting a minor arc structure.

[0006] A vertical connecting plate is provided on the outer side of the arc-shaped clamping plate and is fixedly connected thereto. A claw is provided at the lower end of the vertical connecting plate and the claw is fixedly connected to the lower part of the arc-shaped clamping plate.

[0007] The support frame adopts a three-claw structure.

[0008] The arc length of the pre-tightening plate is 1 / 3 of that of the arc-shaped clamping plate.

[0009] The arc-shaped clamping plate and the vertical connecting plate form a triangular stable structure to support the fixed base plate.

[0010] The fixed base plate is made of cast iron plate.

[0011] The advantages and positive effects of this invention are as follows: By utilizing a fixed base plate made of ferromagnetic material with a fixed structure, a fixed working platform is provided for the magnetic drill on non-ferromagnetic cylindrical tubes. This allows the magnetic drill to operate stably and efficiently on non-ferromagnetic cylindrical tubes such as stainless steel, improving drilling efficiency and solving the problem of magnetic drills being unable to magnetically adhere to non-ferromagnetic cylindrical tubes. The use of an arc-shaped clamping plate and a pre-tightening plate to hold the cylindrical tube securely fixes the fixed base plate to the tube, enabling drilling operations at different angles. Furthermore, this invention has a simple structure and is easy to use. Attached Figure Description
