Description

Technical Field

[0001] The utility model relates to the technical field of rectangular tube processing, in particular to a rectangular tube hole cutting tool. Background Art

[0002] Rectangular tube is a hollow long steel strip, also known as flat tube, flat square tube or square flat tube. When the bending and torsional strength are the same, the weight is lighter, so it is widely used in the manufacture of mechanical parts and engineering structures.

[0003] Rectangular tubes often need to be punched during processing. Generally, the holes on rectangular tubes can be processed by drilling, punching, flame cutting, and plasma cutting. However, the above hole processing processes are not efficient, the punching quality cannot be guaranteed, and are not convenient to use.

[0004] Sometimes there are multiple holes of different diameters on a rectangular tube. The existing method is generally to drill a hole of one diameter and change a device, which has low processing efficiency and high labor intensity.

[0005] In view of the above problems, an improved rectangular tube hole cutting tool is now designed. Utility Model Content

[0006] The utility model aims to provide a rectangular tube cutting tool to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The rectangular tube hole cutting tool comprises an L-shaped base frame, a mechanical indexing turntable is installed at the center position of the upper end of the L-shaped base frame, a rotating square worktable is horizontally installed at the output end of the mechanical indexing turntable, manual clamps for clamping and fixing the rectangular tube are installed on the four sides of the upper end of the rotating square worktable, mechanical arms are installed on the three end points of the upper end of the L-shaped base frame away from the mechanical indexing turntable, and a laser cutter for cutting holes in the rectangular tube is installed at the output end of the mechanical arm.

[0009] As a further solution of the utility model: a support leg for supporting the L-shaped chassis is installed at the lower end of the L-shaped chassis, and a friction pad is installed at the lower end of the support leg.

[0010] As a further solution of the utility model: the interior of the rotating square workbench is provided with supporting ribs for improving the structural strength of the rotating square workbench.

[0011] As a further solution of the utility model: the manual clamp is installed on the rotating square workbench through a slide rail.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model adopts the laser cutting hole technology, has high working efficiency, good product quality, good working intensity, and is suitable for products with high quality requirements and large batches.

[0014] The utility model drives the rotating square workbench to rotate through a mechanical indexing turntable, so that the rectangular tube on the rotating square workbench is moved to three workstations in sequence, each workstation processes a hole diameter, and the processing efficiency is high. After the processing of the three workstations is completed, the rectangular tube is moved to the loading and unloading workstation again, and the staff removes the rectangular tube and replaces it with a new rectangular tube, thereby achieving continuous processing and effectively improving the efficiency of rectangular tube hole cutting processing.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 3 In the embodiment of the utility model, the rectangular tube cutting tool comprises an L-shaped base frame 1, a mechanical indexing turntable 6 is installed at the center position of the upper end of the L-shaped base frame 1, a rotating square worktable 5 is horizontally installed at the output end of the mechanical indexing turntable 6, and a manual clamp 4 for clamping and fixing the rectangular tube is installed on the four sides of the upper end of the rotating square worktable 5, and a mechanical arm 2 is installed on the three end points of the upper end of the L-shaped base frame 1 away from the mechanical indexing turntable 6, and a laser cutter 3 for cutting holes in the rectangular tube is installed at the output end of the mechanical arm 2.

[0021] When in use, the position where the robot arm 2 is not set is the loading and unloading station. Taking the loading and unloading station as the starting point, the three positions of the robot arms 2 in the clockwise direction are the first processing station, the second processing station and the third processing station respectively. At the loading and unloading station, the rectangular tube is clamped and fixed on the rotating square worktable 5 by the manual clamp 4, and then the mechanical indexing turntable 6 is started.
