Description

Technical Field

[0001] The utility model relates to the technical field of steel sections, in particular to an auxiliary tool for milling the end face of a steel column. Background Art

[0002] Box-type steel columns are widely used in steel structure buildings. For example, multiple box-type steel columns are connected to form the column of the steel structure. The verticality of the upper and lower ends of the steel column directly affects the installation accuracy and quality of the building. At present, in order to facilitate the precise connection of box-type steel columns, the upper and lower ends of the steel columns are often milled.

[0003] End milling, also known as planing, is used to mill the bottom end of box steel. It has the following effects:

[0004] 1. The end of the planer is flat, and the length of the butt joint can be better guaranteed, which is conducive to ensuring the accuracy of the butt joint;

[0005] 2. The smooth joint after planing is conducive to ensuring the quality of the weld;

[0006] 3. After planing, a step-like structure will be formed on the end surface, which can replace the role of the lining strip, so there is no need to add a liner.

[0007] However, the existing end milling machines are inconvenient to position due to the large length of the box-type steel columns. There is a lack of fixation on the box-type steel columns, which can easily cause the steel columns to vibrate or shift during the milling process, thereby affecting the end surface processing quality. In severe cases, rework is required, increasing production costs.

[0008] Therefore, an auxiliary tooling for steel column end face milling is proposed, which can assist in fixing the box-shaped steel, which is beneficial to improving the milling accuracy and ensuring the quality and efficiency of milling. Utility Model Content

[0015] In a preferred embodiment of the present scheme, the clamp comprises a C-shaped frame, the top of the C-shaped frame is provided with an inverted L-shaped plate, and the middle of the top plate of the inverted L-shaped plate is screwed with screws; when the C-shaped frame is clamped on the upper edge of the channel steel, the horizontal side plate of the inverted L-shaped plate can be located above the horizontal side plate of the L-shaped stop block;

[0016] When the clamp is used to lock the L-shaped stop block, the screw passes downward through the horizontal side plate of the inverted L-shaped plate and then abuts against the horizontal side plate of the L-shaped stop block.
