[0030] The following first describes in detail the large-scale rotary surface self-adjusting leveling processing equipment according to an embodiment of the present invention in conjunction with the accompanying drawings.

[0031] like Figure 1As shown, the large-scale rotating surface self-adjusting leveling processing equipment of the embodiment of the present invention includes a rotating center base 1, a rotating center axis 2, a frame arm 3, a driving part 4, a milling part 5, a laser emitting part, and a laser receiving part. The rotary center base 1 is used to be fixed at the center of a circular workpiece 6 to be milled; the bottom end of the rotary center axis 2 is connected to the rotary center base 1; the first end of the frame arm 3 is rotatably connected to the upper end of the rotary center axis 2; the upper end of the driving part 4 is connected to the lower end of the second end of the frame arm 3, and the lower end of the driving part 4 is provided with a driving wheel, which is used to be set on the upper surface of the workpiece 6 to be milled; the milling part 5 is connected to the lower end of the second end of the frame arm 3; the laser emitting part includes a laser emitter 7 and a emitter support frame 8, the emitter support frame 8 is used to be connected to the workpiece to be milled, the laser emitter 7 is connected to the upper end of the emitter support frame 8, and the laser emitter 7 is provided with a rotatable laser emitting head; the laser receiving part includes a laser receiver 9 and an analyzer, the laser receiver 9 is fixed to the upper end of the second end of the frame arm 3, the laser receiver 9 is provided with a laser receiving board, the laser receiving board is used to receive the laser projected by the laser emitting head, and the analyzer is connected to the laser receiver 9 for analyzing the movement trajectory of the laser on the laser receiving board.

[0032] The processing size of marine engineering products is relatively large, and the processing diameter is usually 28-43m, while the processing accuracy of flatness is less than 3mm. It is often difficult to achieve such high accuracy with ordinary measurement methods. Therefore, the present invention designs a set of laser equipment to address this problem, including a laser transmitter 7 and a laser receiver 9. The following specifically introduces the installation process, adjustment process and processing process of the large-scale rotary surface self-adjusting leveling processing equipment equipped with the laser equipment.

[0033] The installation process of the large rotary surface self-leveling processing equipment is as follows:

[0034] 1) After completing the preliminary preparations, first install the slewing center base 1, ensuring that the center of the slewing center base 1 coincides with the center of the component.

[0035] 2) Install the rotary center axis 2 at the center of the rotary center base 1 and adjust the horizontality. Adjust the rotary center axis 2 through the auxiliary bracket so that it coincides with the center of the workpiece 6 to be milled.

[0036] 3) Connect one end of the assembled rack arm 3 to the central axis of rotation 2, and place the other end on the auxiliary bracket, and adjust the rack arm 3 to a roughly horizontal state through the auxiliary bracket.

[0037] 4) Install the driving unit 4 and the milling unit 5 at a suitable position at the other end of the frame arm 3 according to the milling width.

[0038] 5) Install the lower end of the transmitter support frame 8 to the center of the workpiece to be milled 6 and ensure that the upper end basically coincides with the center of the workpiece to be milled, then install the laser transmitter 7 to the upper end of the transmitter support frame 8 and adjust it to a horizontal state through an auxiliary bracket and ensure that the laser transmitter head coincides with the center of the workpiece to be milled, and finally install the laser receiver 9 at a position of the frame arm 3 close to the drive part 4.

[0039] 6) Install the electrical box, control box, hydraulic station and other equipment at the designated location, and connect the lines and pipes as required.

[0040] The adjustment process of the large rotary surface self-leveling processing equipment is as follows:

[0041] 1) Remove the auxiliary bracket under the rack arm 3, place a level on the milling part 5, and adjust the other end of the rack arm 3 and the milling part 5 to a horizontal state according to the measurement data.

[0042] 2) After the milling section 5 is adjusted horizontally, the position and angle of the laser receiver 9 are manually adjusted to be in an ideal receiving state.

[0043] The operation process of the large rotary surface self-leveling processing equipment is as follows:

[0044] 1) Check the position of the milling section 5 to ensure that the milling section 5 does not hit the workpiece 6 to be milled and other objects during idle travel.

[0045] 2) Start the driving unit 4 to move in one circle. The laser transmitter 7 rotates with the laser receiver 9 at the same angular velocity in the manual state to project the laser onto the laser receiving plate. When the driving unit 4 moves on the workpiece 6 to be milled, the laser receiver 9 will fluctuate due to the unevenness of the surface, and the position of the laser on the laser receiving plate will also change accordingly. After moving in one circle, the analyzer calculates the flatness of the surface of the workpiece 6 to be milled based on the motion trajectory of the laser on the laser receiving plate, thereby determining the feed amount of the milling unit 5.

[0046] 3) According to the calculation results of the analyzer, move the equipment to the highest point of the workpiece 6 to be milled, and manually adjust the milling part 5 slowly downward. When the milling part 5 touches the workpiece 6 to be milled, set this point as the zero position.

[0047] 4) According to the milling requirements, the milling part 5 is adjusted to a suitable feed depth, and then the driving part 4 and the laser emitting part are adjusted to the automatic operation state to perform milling.

[0048] 5) After one circle is completed, the travel drive mechanism pauses, moves the milling part 5 to the next predetermined position, and then continues milling, and repeats this step until the required depth is reached.

[0049] The large rotary surface self-adjusting leveling processing equipment of the present invention can measure the flatness of the surface of the workpiece to be milled by laser equipment during the milling process, thereby more accurately adjusting the feed depth of the milling part 5, effectively improving the processing accuracy of the workpiece to be milled 6.

[0050] Furthermore, if Figure 1 As shown, a laser protection tube 10 is also included, one end of the laser protection tube 10 is arranged at the laser emitting head, and the other end is arranged at the laser receiving board.

[0051] Due to the harsh processing environment, some obstructions may appear during the laser projection process, affecting the laser projection quality and thus the analysis results. To address this problem, the device is equipped with a laser protection tube 10. The laser emitted by the laser transmitter 7 is irradiated onto the laser receiving board through the laser protection tube 10. The entire path is not affected by external factors, thereby ensuring the accuracy of the analysis results.

[0052] Furthermore, the rotating center axis 2 is formed into a hollow shape, and the position of the rotating center base 1 connected to the rotating center axis 2 is formed into a hollow shape. The lower end of the launcher support frame 8 passes through the interior of the rotating center axis 2 and the rotating center base 1 and is connected to the milling part.

[0053] During the milling process, the rotation center of the laser should be ensured to coincide with the center of the workpiece 6 to be milled and the horizontality of the laser should not be affected by the movement of the frame arm 3. In view of this requirement, the equipment designs the central axis 2 of the rotation to be hollow, and passes the transmitter support frame 8 through the hollow part to be installed at the center position of the workpiece 6 to be milled, so that the transmitter support frame 8 does not contact the central axis 2 of the rotation. This structure not only ensures the coincidence of the centers of the two, but also ensures that the transmitter support frame 8 is not affected by the movement of the central axis 2 of the rotation and the frame arm 3.

[0054] Furthermore, the driving parts 4 include two driving parts 4 , which are respectively connected to two sides of the milling part 5 .

[0055] A driving part 4 is respectively arranged on both sides of the milling part 5, which can increase the stability of the frame arm 3 when rotating, thereby improving the processing accuracy of the workpiece to be milled.

[0056] Furthermore, if Figure 2 As shown, the laser receiver 9 and the laser emitting head each include two, and the two laser receivers 9 are respectively connected to both sides of the upper end of the second end of the rack arm 3 to respectively receive the lasers emitted by the two laser emitting heads.

[0057] The ups and downs of the two driving parts 4 during walking are not consistent, so two laser receivers 9 are installed near the two driving parts 4 to monitor the ups and downs of the two driving parts 4, which can increase the accuracy of measurement.

[0058] Furthermore, a telescopic portion is provided at the upper end of the driving portion 4 , and the driving portion 4 is connected to the second end of the frame arm 3 via the telescopic portion.

[0059] The driving part 4 adjusts the position of the frame arm 3 through the telescopic part that can be adjusted up and down, which enhances the flexibility of the equipment, reduces the use of auxiliary brackets, and improves production efficiency.

[0060] Furthermore, if Figure 2 As shown, the revolving center base 1 is formed in a cross shape, and the four ends of the revolving center base 1 are provided with adjusting parts 11, and the adjusting parts 11 are used to adjust the height of the ends of the revolving center base 1.

[0061] The levelness of the slewing center base 1 directly affects the levelness of the frame arm 3. Therefore, the device adopts a simple and stable cross-shaped structure, and height adjustment parts 11 are installed at the four ends to adjust the levelness of the slewing center base 1.

[0062] Furthermore, the adjusting portion 11 includes a screw hole formed at an end portion and a bolt fitted in the screw hole, and a lower end of the bolt protrudes from the screw hole and forms a bottom plate.

[0063] When installing the slewing center base 1, the height of each end can be adjusted by simply rotating the bolts, and the structure is simple and the operation is convenient.

[0064] Furthermore, if Figure 1 As shown, the rack arm 3 includes a plurality of connecting arms 12, and the plurality of connecting arms 12 are connected together head to tail.

[0065] The rack arm 3 is composed of a plurality of connecting arms 12 , so the length of the rack arm 3 can be adjusted by adding or removing the connecting arms 12 , thereby increasing the flexibility of the device.

[0066] Furthermore, a plurality of first mounting portions spaced apart from each other in an upper and lower direction are provided at the tail of the connecting arm 12 , and a second mounting portion cooperating with the first mounting portion is provided at the head of the connecting arm 12 .

[0067] During installation of the connecting arm 12 , the second mounting portion may be mounted to a suitable first mounting portion, thereby satisfying the height requirement of the rack arm 3 .

[0068] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
