[0035] Figure 1 The lifting lug main board 100 to be processed is shown. In the process of manufacturing the lifting lug main board 100, a large number of grooves need to be processed before it can be used for welding. For example, a plate with a thickness of nearly 60 mm needs to be grooved, but the traditional groove processing method relies on manual hand-held cutting torque, which is not accurate enough, and due to the impact force during the cutting process, manual labor cannot move stably, the cutting quality cannot be guaranteed, and there are risks.

[0036] In order to solve the above problems, the utility model provides a groove processing equipment, which can meet various needs when opening the groove of the lifting eye main board, is safe to use, and has accurate processing.

[0037] Reference Figure 2As shown, the groove processing equipment includes a fixed support 10, a multi-dimensional walking mechanism 20 and a special-shaped cutting mechanism 30.

[0038] The multi-dimensional walking mechanism 20 is arranged on the fixed support 10, and includes at least two modules of a first-dimensional track module, a second-dimensional track module, and a third-dimensional track module. The first dimension, the second dimension, and the third dimension are orthogonal to each other. Figure 2 In the embodiment shown, the first dimension is the X-axis direction, the second dimension is the Y-axis direction, and the third dimension is the Z-axis direction. The multi-dimensional walking mechanism 20 includes a combination of a first-dimensional track module 201 and a second-dimensional track module 202. This combination can be used to perform a plane position transformation, which is used to process the groove of the straight part position, and can also be used to adjust the position of the special-shaped cutting mechanism 30.

[0039] Preferably, the multi-dimensional walking mechanism 20 is placed parallel to the ground with the ground being used as a parallel reference plane. When placed parallel to the ground on the platform, it plays a role in positioning and walking within the range in which the lateral and longitudinal walking mechanisms can walk.

[0040] The structures of track modules in each dimension are similar. Figures 11 to 13 The second dimension track module 202 shown as an example includes a cantilever structure 25 and a track 26 extending along the second dimension. The cantilever structure 25 is used to install a lead screw module 27 of a transverse walking mechanism along the second dimension to drive the special-shaped cutting mechanism 30 to move transversely along the Y direction.

For the first dimension track module 201 installed on the fixed support 10, the fixed support 10 is provided with a corresponding support frame 109 and a connecting frame 108, and the connecting frame 108 extends along the dimension of the track module connected thereto. Fig.14In the illustrated embodiment, the connecting frame 10 is connected to the first dimension track module 201, and the connecting frame 108 extends along the first dimension direction.

[0043] Back to Figure 2 The special-shaped cutting mechanism 30 is movably arranged on the multi-dimensional walking mechanism 20, and can meet the needs of opening arc grooves with different radii. Figure 3 As shown, the special-shaped cutting mechanism 30 includes a turntable module 31, a diameter reducing structure 32 and a cutting torch device 33. The turntable module 31 is connected to the diameter reducing structure 32 so that the diameter reducing structure 32 moves in a circular motion, thereby providing an arc path required for circular bevel cutting. The cutting torch device 33 is movably connected to the diameter reducing structure 32, and the diameter reducing structure 32 is used to change the radius size of the cutting torch device 33 when it rotates.

[0044] The special-shaped cutting mechanism 30 enables the cutting torch to be suitable for the path change of various groove cutting with functional laws, such as circular chamfer, oblique straight groove, straight groove, etc. The cutting torch device 33 is connected to the diameter reducing structure 32 through the corner flange 34. The other side of the corner flange 34 is also connected to the driving mechanism 35 of the special-shaped cutting mechanism 30. The driving mechanism 35 is used to provide a rotational driving force to the cutting torch device 33. Figure 4 and Figure 5 It is understood that the driving mechanism 35, the reducing structure 32 and the cutting torch device 33 are connected.

[0045] Reference Figure 6 As shown, the driving mechanism 35 includes a servo motor, a worm gear, a worm and a connecting shaft. Specifically, it includes an end cover 351, a connecting shaft 352, a worm gear 353, a bearing 354, a skeleton oil seal 355, a worm cover 356, a worm gear housing 357, a circlip 358, a worm 359, a driven gear 360, a mounting flange 361, a driving gear 362 and a servo motor 363, etc. The servo motor drives the worm gear to reduce speed and then drives the cutting torch.

[0046] The connecting shaft 352 passes through the hole 340 on the corner flange 34 and is connected to the cutting torch device 33. Figure 7 As shown, the cutting torch device 33 includes a cutting torch 331, a cutting torch mounting flange 332, a mounting back plate 333 and a connecting bolt 334 which are connected in sequence. The mounting back plate 333 is connected to the corner flange 34 through the connecting bolt 334. The connecting shaft passes through the mounting back plate and is connected to the cutting torch mounting flange 332. The cutting torch 331 is connected to the driving mechanism to cut the steel plate groove.

[0047] Turntable module 31 Figure 8As shown, its function is to drive the variable diameter structure 32 to do circular motion, providing the arc path required for circular groove cutting. The turntable module 31 includes a servo motor 311, a reducer 312, a reducer 313 and a connecting member 314, and the connecting member 314 is fixedly connected to the variable diameter structure 32.

[0048] The variable diameter structure 32 is as follows Fig. 9 As shown, it includes a slider 321, a screw module 322, a reducer 323, a servo motor 324 and a mounting back plate 325. The slider 321 is driven by the screw module 322 to change the distance from the turntable module 31. When the fillet groove is cut, the size of the rotation radius is changed by the slider 321. The slider also serves to connect the corner flange and the turntable module.

[0049] Combine the following Figures 15A-15H , the use process of groove processing equipment is explained.

[0050] First, when processing the groove of the lifting ear mainboard, choose the groove processing equipment of appropriate size according to the size and model of the lifting ear mainboard. Fig.15A As shown, move the lifting lug mainboard to the working area of ​​the groove processing equipment and place it on a stand of suitable height. Before use, ensure the normal operation of various components and accessories.

[0051] like Fig. 15B As shown, according to the size of the material of the lifting ear mainboard, the X-direction and Y-direction track modules are adjusted, and the special-shaped cutting mechanism 30 is moved to the starting point U of the groove cutting of the lifting ear mainboard, so that the cutting torch 331 is aligned with the groove starting point U.

[0052] like Fig. 15C As shown, the angle between the cutting torch 331 and the lifting ear mainboard 100 is adjusted, and the driving mechanism 35 and the turntable module 31 are started, so that the cutting torch 331 is rotated to the required cutting groove angle with the lifting ear mainboard surface as the rotation reference.

[0053] like Fig.15D As shown, the lead screw module in the first-dimensional track module 201 along the X-axis direction is started, and the cutting torch 331 moves along the straight groove section of the ear mainboard toward the -X direction until the straight groove cutting is completed, and the first-dimensional track module 201 stops moving.

[0054] like Fig.15E As shown, after completing the straight part, when the cutting torque 331 is ready to be tangent to the circular guide angle W, continue to adjust the X-axis horizontal and Y-axis longitudinal walking mechanisms to make the center of the rotating output shaft of the turntable module 31 coincide with the center of the fillet circle, adjust the variable diameter structure 32 to make the relative distance between the cutting opening of the cutting torch and the center of the rotating output shaft of the turntable module coincide with the radius of the fillet groove of the lifting ear mainboard, and start cutting the arc groove of the lifting ear mainboard.

[0055] like Fig.15F As shown, after the adjustment is completed, the turntable module 31 is started along the direction V to start cutting the groove of the rounded part.

[0056] like Figure 15G As shown, after the turntable module rotates 90°, the chamfer groove cutting is completed. After the circular chamfer W groove cutting is completed, the turntable module stops and starts cutting the straight part L groove.

[0057] like Fig.15H As shown, after the chamfer groove cutting is completed, the second-dimensional track module 202 along the Y-axis direction is started to walk the horizontal straight path to complete the cutting of the straight portion L. Until it is tangent to the next chamfer, the above steps are repeated. It can be understood that the walking path is adjusted accordingly based on different groove styles.

[0058] The above-mentioned groove processing equipment realizes multi-dimensional automatic cutting through a multi-dimensional walking mechanism and a special-shaped cutting mechanism, with full automatic control, without relying on manual operation, thus improving construction safety and reliability.
