[0001] The utility model relates to the technical field of edge milling machines, in particular to an angle adjustment device for a milling cutter head of an edge milling machine. Background Art

[0002] Edge milling machine is a kind of welding auxiliary equipment which adopts the working principle of high-speed milling of cutter disc. It is specially used for making weld grooves for steel plates before welding. It is widely used in boiler and pressure vessel manufacturing industry, shipbuilding, electric power, petroleum, chemical machinery, and engineering machinery manufacturing. It can process bevel edges, straight edges, and U-shaped slopes of various medium and low carbon steel plates, stainless steel plates and aluminum plates before welding.

[0003] At present, when the existing milling machine is in use, in order to realize the processing of the down-slope without flipping the steel plate, the staff is required to manually turn the rocker to flip the milling assembly to rotate the angle of the milling head 180 degrees. Since the structure of the milling assembly is relatively complex and the volume is large, the staff needs to expend a lot of physical strength to complete the process of adjusting the angle. Therefore, we propose a milling machine milling head angle adjustment device to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-4 , a device for adjusting the angle of a milling cutter head of a milling machine, comprising a frame 1, a milling cutter assembly 2 is installed inside the frame 1, the specific working principle of the milling cutter assembly 2 is the existing technology, and no further details are given here. A rotating shaft 3 is connected to the side of the milling cutter assembly 2, and the rotating shaft 3 passes through the inner wall of the frame 1 and is sleeved with a gear 4, a connecting member 5 is connected to the side of the frame 1, and a cylinder 6 is connected to the upper side of the connecting member 5, the top of the cylinder 6 is connected to a moving frame 8 through a connecting plate 7, and the inner side of the moving frame 8 is evenly distributed with teeth that are compatible with the gear 4, through the distribution of the teeth, the gear 4 and the moving frame 8 can be meshed, so that in the process of the moving frame 8 moving up and down, the gear 4 can be driven to flip, thereby realizing the adjustment of the angle of the milling cutter head inside the milling cutter assembly 2.

[0023] Further, see Figure 4 It can be seen that the connecting member 5 is set as an L-shaped structure, and the lower side of the connecting member 5 is connected to the frame 1 by bolts. The connecting member 5 set by the L-shaped structure can facilitate the staff to disassemble the faulty cylinder 6 for maintenance, thereby facilitating the staff to perform maintenance operations.

[0024] Further, see Figure 2 and Figure 4 It can be known that the upper side of the connecting member 5 is symmetrically connected with a guide rod 9, the movable frame 8 is arranged as a U-shaped structure, and a movable groove adapted to the guide rod 9 is opened inside the movable frame 8. Through the mutual cooperation between the movable groove and the guide rod 9, when the cylinder 6 is started, the movable frame 8 can be driven to slide along the outer wall of the guide rod 9, thereby guiding the movable frame 8 to ensure the stable up and down movement of the movable frame 8.

[0025] Further, see Figure 1 and Figure 3 It can be seen that the side of the frame 1 is symmetrically distributed with support plates 13, and the side where the support plates 13 are close to each other is provided with a covering plate 14. Through the mutual cooperation of the support plates 13 and the covering plates 14, the gear 4 and the moving frame 8 can be covered and protected.

[0026] Further, see Figure 1 and Figure 3It can be known that the edge positions of the covering plate 14 are respectively connected with the clamping strips 15, the interior of the supporting plate 13 is provided with a docking groove matched with the clamping strips 15, and the top of the covering plate 14 is connected with the handle 16. Through the docking groove provided in the supporting plate 13, the covering plate 14 and the supporting plate 13 are connected by mortise and tenon joints. Therefore, when the device fails, the staff only needs to pull the covering plate 14 to drive the clamping strips 15 to be pulled out from the docking groove, so as to realize the open maintenance of the gear 4 and the movable frame 8. Through the setting of the handle 16, it is convenient for the staff to manually pull the covering plate 14.

[0027] Further, see Figure 3 It can be known that a threaded rod 10 is connected to the front of the gear 4, and an indicator mark 12 is provided on the front of the threaded rod 10 through the inner wall of the covering plate 14. The limit of the indicator mark 12 can effectively ensure the tightness of the covering plate 14 during the covering process to prevent it from moving easily. The indication of the indicator mark 12 can facilitate the staff to judge the rotation angle of the shaft 3 on the side of the body, thereby effectively improving the convenience of using the device.

[0028] Further, see Figure 3 It can be known that the end of the indicator mark 12 is connected to the threaded sleeve 11, and the threaded sleeve 11 is sleeved on the outside of the threaded rod 10. Through the threaded cooperation of the threaded sleeve 11 and the threaded rod 10, when the staff needs to remove the cover plate 14, the threaded sleeve 11 can be first rotated out from the outside of the threaded rod 10, thereby facilitating the staff to remove the indicator mark 12.

[0029] Working principle: When the utility model is in use, the staff can first push the device to the side of the steel plate, and then start the milling assembly 2 to realize the milling operation of the steel plate. After completing the milling of the upper side of the steel plate, the staff can push the device to the side of the steel plate, and then start the cylinder 6, so that it drives the connecting plate 7 and the movable frame 8 to be pushed upward. In the upward process of the movable frame 8, the gear 4 meshing therewith is driven to rotate. Since the gear 4 is fixedly sleeved on the outer side of the rotating shaft 3, the flipping operation of the rotating shaft 3 and the milling assembly 2 can be driven. In the upward process of the movable frame 8, it is forced to slide along the outer surface of the guide rod 9, thereby guiding the movable frame 8. In addition, in the process of the coordinated operation of the gear 4 and the movable frame 8, the mutual cooperation of the covering plate 14 and the supporting plate 13 can effectively prevent the entry of debris. The above is the entire working principle of the utility model.

[0030] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.
