Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding and large steel structure manufacturing equipment, and in particular to a hanging code root removal milling method. Background Art

[0002] The lifting brackets used in ships and steel structures are usually installed on the ship and steel structure sections or the whole section by welding. The lifting brackets are the load-bearing components during the lifting, hoisting, shifting, turning over and loading of the ship and steel structure sections or the whole section. After the sections or the whole section are assembled, the lifting brackets need to be cut off with a cutter along the welding part. The weld root left is generally 30-50mm. The current removal method is to use a carbon planer or a cutter to remove it, which will not only damage the parent material, but also the paint under the lifting bracket. At the same time, the iron oxide cut off cannot be reused. Summary of the invention

One person can take care of 2-3 units at the same time, which greatly improves production efficiency and liberates manpower. The paint under the hanging weights will not be damaged, and the iron filings milled off can be reused to generate certain value. The base material will not be damaged, and consumables such as oxygen, propane, and welding materials are saved.

DETAILED DESCRIPTION

[0017] See also Figure 1-4 The present invention relates to a hanging code root removal milling machine, comprising a platform base 1, a magnetic base 2, a transverse lead screw 3, a spindle base 4, a power spindle 5 and a vertical lead screw 6. The platform base 1 is provided with a magnetic base 2 at the bottom, and is adsorbed on the position of the hanging code to be cut through the magnetic base 2. The transverse lead screw 3 is supported on the platform base 1, and the transverse lead screw 3 is driven by a transverse driving motor 7. The nut of the transverse lead screw 7 is connected to the spindle base 4. The spindle base 4 is sleeved with a power spindle 5. The power spindle 5 is installed with a milling cutter 8 after the bottom of the power spindle 5 extends out of the spindle base 4. The top is connected to the spindle motor 10 through a gear box 9 and is driven to rotate by the spindle motor 10. The vertical lead screw 6 is supported on the spindle base 4, and the nut 11 of the vertical lead screw 6 is fixed on the spindle base 4. The top of the vertical lead screw 6 is connected to a lifting motor 12, and the lifting motor 12 is fixed on the gear box 9.

[0018] The platform base 1 is provided with a lifting lug 13 to facilitate lifting the device to the position where the hanging code is to be cut.

[0019] The spindle base 4 is provided with a mounting sleeve 4.1 corresponding to the power spindle 5, and the mounting sleeve 4.1 is sleeved outside the power spindle 5.

[0020] The platform base 1 is provided with lifting columns 14 at the front and back. The lifting columns 14 are lifted and lowered synchronously to raise or lower the platform base 1. The lifting columns 14 include an outer square tube, an inner square tube and a lifting screw. The outer square tube is provided with an inner square tube and a lifting screw. The lifting screw sleeve is provided with a square nut, and the square nut is connected to the inner square tube. The bottom of the inner square tube is connected to a roller or a roller group. The lifting screw drives the square nut and the inner square tube to rise and fall by rotating the handle 15. Since the roller connected to the inner square tube acts on the ground or the cutting plane, the rotating handle actually realizes the lifting and lowering of the outer square tube. When the hanging code root removal milling machine moves on the ground, the platform base and the magnetic seat are lifted, and the rollers touch the ground to move the hanging code root removal milling machine. When the hanging code root removal milling machine is lifted to a suitable position, the platform base is lowered to make the magnetic seat descend and adsorb the cutting plane.

[0021] A distribution box 16 is provided at the rear side of the platform base 1 , and the distribution box 16 is fixed to the extension plate 1 . 1 at the rear side of the platform base 1 via a detachable support seat 17 .

[0022] The magnetic base 2 is divided into two types: fixed and movable. Two fixed magnetic bases 2 are arranged on the front and rear sides of the platform base, and one movable magnetic base 2 is arranged on the rear side of the platform base 1. The extension plate 1.1 is hinged to the connecting plate 18, and the connecting plate 18 is hinged to the movable magnetic base 2. An angle adjustment button 19 is provided between the connecting plate 18 and the extension plate 1.1. When the cutting area is uneven, the angle of the magnetic base 2 is adjusted by rotating the angle adjustment button 19 so that the bottom surface of the magnetic base 2 fits with the appropriate position to ensure that the hanging code root removal milling machine is firmly adsorbed.

[0023] The detachable support base 17 is fixed on the extension plate 1.1 via a magnetic switch 20.

[0024] The transverse lead screw 3 and the vertical lead screw 6 are both provided with telescopic sleeves to prevent iron filings from entering.

[0025] A method for milling a hanging code to remove roots comprises the following steps: Cut the hanging weight 21 on the hanging weight cutting plane in advance, leaving the hanging weight root. The hanging weight root should be kept at a height of 5-10mm to avoid damaging the ship section (such as Figure 4 ); Lift the hanging code root removal milling machine to the hanging code cutting position, adjust the handle to lower the platform base, and the bottom surface of the magnetic seat at the bottom of the platform base will contact the hanging code cutting platform. Rotate the button of the magnetic seat to make the magnetic seat adsorb on the cutting platform; The spindle motor drives the power spindle and the milling cutter on it to rotate, and the transverse drive motor drives the transverse screw to move; the transverse drive motor drives the transverse screw to move, and the nut of the transverse screw drives the spindle base, the power spindle, the gear box and the spindle motor to move laterally synchronously. In order to make the spindle base move smoothly laterally, slide rails are provided on the front and rear sides of the platform base corresponding to the spindle base; the lifting motor drives the vertical screw to move, and the nut of the lifting motor is fixed on the spindle base and does not lift or lower, then the vertical screw lifts and lowers, driving the gear box, the power spindle and the milling cutter to lift and lower synchronously, adjusting the single milling amount of the milling cutter, and removing the root of the hanging code through multiple milling, thereby greatly improving the cutting efficiency of the hanging code.

[0026] The present invention hoists the hanging weight root removal milling machine onto the main deck or the large cabin, and can push it to the top of the area where the roots need to be removed, align it with the root removal position, raise the front and rear lifting devices, let the magnets completely contact the ground, and then flip the magnet switch (closed) to start the machine to mill the roots of the hanging weights, thereby greatly improving the efficiency of the hanging weight root removal.
