Description

Technical Field

[0001] The utility model relates to the technical field of crane structure processing, in particular to a portal structure drilling machine. Background Art

[0002] For offshore cranes with large lifting tonnage, the flange thickness of the back-mounted support is about 200-300mm. When drilling holes in the flange structure of the crane, more than 200 inner holes with a diameter of 80-100mm need to be drilled in the flange. Conventional drilling machines are generally equipped with twist drills, which have a slow drilling speed. When drilling holes in the flange structure of the crane with a drilling machine equipped with a twist drill, the drilling time is increased due to the large thickness of the flange workpiece; and for holes with large diameters (such as Φ80 holes), the use of twist drills cannot form them in one step. It is necessary to drill a shallow hole for positioning first, then drill a small hole, and finally expand the hole to the right position.

[0003] The inventors found that when the current drilling machine is used to drill the crane flange structure, its processing efficiency cannot meet the production progress requirements; and the high-efficiency drill bits mainly include U-drills (or violent drills). The U-drill tool has good chip removal performance and can drill holes continuously, so the drilling efficiency is very high. It is suitable for drilling the crane flange structure. However, when the current drilling machine equipped with a violent drill is used to process the workpiece, due to the influence of the processing intensity, the U-drill tool is prone to cause violent vibration of the rocker arm during the rapid drilling process, which not only reduces the drilling accuracy of the tool, but also damages the tool in severe cases. Therefore, the current drilling machine is not designed to consider the ability to match the high-efficiency drill bit. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a gate-type structure drilling machine, which is equipped with a rocker arm locking rod and a magnet for easy disassembly. When drilling, the rocker arm is relatively fixed to the workpiece by the rocker arm locking rod and the magnet, which can effectively prevent the rocker arm from vibrating and damaging the violent drill during drilling. The rocker arm, rocker arm locking rod, magnet and drilling tool group form a stable gate-type structure to ensure stability during drilling and ensure drilling accuracy.

[0007] As a further implementation, the drilling machine includes a drilling machine base, and the drilling machine base is used to be arranged in the center hole of the flange.

[0008] As a further implementation, a column is provided on the top of the drilling machine base, the rocker arm is installed on the column through a sleeve, and the column drives the rocker arm to rotate relative to the column through a first driving mechanism.

Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0025] Embodiment 1

[0026] In a typical implementation of the present invention, reference is made to Figure 1 As shown, a gate-type structure drilling machine includes a drilling machine, on which a rocker arm 4 is provided, a slider 7 is provided on the rocker arm 4, a drilling tool group 13 is provided at the bottom of the slider 7, the drilling tool group 13 includes a violent drill, a rocker arm locking rod 5 is installed on the rocker arm 4, the top end of the rocker arm locking rod 5 is fixedly connected to the rocker arm 4, and the bottom end is connected to a magnet 6, the rocker arm locking rod 5 absorbs the workpiece through the magnet 6, the rocker arm locking rod 5, the magnet 6, the rocker arm 4 and the drilling tool group 13 form a gate-type structure; the drilling tool group 13 is connected to a cooling mechanism.

[0027] In this embodiment, a rocker arm locking rod 5 is provided, and the rocker arm 4 fixes the crane flange workpiece through the rocker arm locking rod 5 and the magnet 6, thereby preventing the drill bit tool from vibrating violently during drilling, extending the service life of the tool, and improving the drilling accuracy.

[0028] like Figure 1 As shown, the drilling machine includes a drilling machine base 1, which is used to be set in the center hole of the flange. A column 2 is provided on the top of the drilling machine base 1. A rocker arm 4 is installed on the column 2 through a sleeve 3, and the column 2 drives the rocker arm 4 to rotate relative to the column 2 through a first driving mechanism. The rocker arm 4 is connected to the slider 7 through a horizontal driving mechanism, so that the slider 7 slides horizontally on the rocker arm 4, thereby adjusting the drilling radius. The bottom of the slider 7 is connected to the tool assembly mounting seat 14 through a vertical driving mechanism, so that the tool assembly mounting seat 14 moves vertically, so that the tool is close to the workpiece when drilling.

[0029] A drilling tool set 13 is arranged at the bottom of the tool set mounting seat 14, and the tool set mounting seat 14 drives the violent drill to work through the second driving mechanism. The drilling tool set of this embodiment adopts a violent drill, and the drilling tool set mainly includes a blade, a center drill, a tool rod, and a tool holder. The violent drill is an existing tool. When installing the violent drill, it is necessary to select a suitable Morse taper shank and an externally cooled tool handle. The Morse taper shank needs to match the drilling machine. The externally cooled tool handle and the Morse taper shank are an integrated structure and are installed on the tool set mounting seat 14.

[0030] It should be noted that, in this embodiment, the rotation of the rocker arm 4 relative to the column 2, the movement of the slider 7 relative to the rocker arm 4, the vertical movement of the tool assembly mounting seat 14, and the driving of the tool are all prior arts, and the first driving mechanism, the horizontal driving mechanism, the vertical driving mechanism, and the second driving mechanism are all prior arts and will not be elaborated here.

[0031] A bracket 12 is provided on the side of the tool assembly mounting seat 14, and a cooling mechanism needs to be configured on the side of the drilling machine. The pipeline of the cooling mechanism is fixed through the bracket 12 and aligned with the tool to achieve cooling during drilling.

[0032] like Figure 1 As shown, the cooling mechanism includes a cooling box 9 and an air compressor 8. The cooling box 9 is provided with a coolant 10 and a cooling pump 11. The pipeline of the cooling box 9 is fixed to the external cooling handle at the violent drill through a bracket 12. The pipeline of the air compressor 8 is fixed to the external cooling handle at the violent drill through a bracket 12, so that the coolant and compressed air are connected to the external cooling handle of the violent drill, and the pipeline of the air compressor 8 is connected to the pipeline end of the cooling box 9 through a three-way valve. The coolant 10 is discharged through the cooling pump 11 and the pipeline, and is collected with the compressed gas of the air compressor 8 to cool the violent drill together.

[0033] It can be understood that the cooling box 9 is filled with a mixed coolant of the original coolant and water, the cooling pump 11 is used to accelerate the transfer of the coolant, and the compressed air needs to use an air compressor or centralized compressed air supply to provide cooling gas for the external cooling tool holder for accelerated transfer of the coolant and purging of iron chips.

[0034] When drilling holes in the crane flange structure, you need to select a suitable drilling machine, which means a drilling machine that matches the required drilling diameter. For example, if you want to drill a hole with a diameter of 80, you need to match a Z100 drilling machine. The drilling machine base is placed inside the workpiece to facilitate hole processing when the workpiece is not easy to move.

[0035] When drilling, you need to select a suitable U drill tool. Select the appropriate U drill tool according to the diameter of the processed hole. For example, if you need to drill an inner hole with a diameter of Φ80, you need to match and select a Φ80 U drill tool (violent drill).

[0036] The two ends of the rocker arm locking rod are connected to the rocker arm and magnet by bolt assemblies, which is convenient for disassembly. When drilling, the rocker arm is fixed relative to the workpiece by the rocker arm locking rod and magnet, which can effectively prevent the rocker arm from vibrating during drilling and damaging the violent drill. Through the setting of the rocker arm locking rod and magnet, the rocker arm, rocker arm locking rod, magnet and drilling tool form a stable door-shaped structure. During processing, the drilling tool group on the rocker arm drills the workpiece, and the rocker arm is also adsorbed with the workpiece by the rocker arm locking rod and magnet to prevent the rocker arm from vibrating during drilling and causing damage to the tool, thereby ensuring stability during drilling. It is understandable that the rocker arm locking rod and the workpiece can be fixed by magnets or spot welding.

[0037] This embodiment utilizes the characteristics of the drilling machine's rocker arm being rotatable and the tool being movable in the direction of the crossbeam. Multiple holes can be drilled continuously without moving the machine tool. This embodiment is particularly suitable for scenarios where the line connecting the hole centers is not a straight line. When the rocker arm rotates to the next drilling position, it is necessary to first disassemble the rocker arm locking rod. After the rocker arm is rotated into place, the rocker arm locking rod is reinstalled. The bolt holes required for the installation of the rocker arm locking rod can be opened according to specific circumstances.

[0038] The drilling machine of this embodiment has the ability to be equipped with an efficient drill bit by setting a rocker arm locking rod and a magnet, ensuring the stability and drilling accuracy of the drill bit. The violent drill setting can drill quickly and form a hole in one go, with high drilling efficiency, simple and easy controllable process, and fast processing speed. It is suitable for processing inner holes or flange inner holes with a diameter of less than 150 mm and a depth of less than 300 mm.

[0039] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
