The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] See Figures 1 to 4 This embodiment provides a chamfering cutter head for use in an automatic chamfering device, the chamfering cutter head comprising:

[0034] Base spindle 1 is detachably connected to the tool holder;

[0035] A lifting base 3 is fitted over the base and is connected to the base via a spline 14. The lifting base 3 is used to reciprocate up and down along the base.

[0036] Elastic element 4 is disposed on the side wall of the base, and the elastic element 4 is used to push the lifting base 3 downward.

[0037] The upper blade holder 5 is detachably connected to the bottom of the lifting base 3, and the multiple upper blades 51 of the upper blade holder 5 extend downward;

[0038] Pressure plate 7, sleeved outside the upper knife holder 5, is rotatably connected to the lifting base 3, and is used to press down on the top surface of the steel plate; and

[0039] The lower tool holder 6 is located below the upper tool holder 5. The lower tool holder 6 is connected to the base shaft 1, and a plurality of lower blades 61 of the lower tool holder 6 extend upward.

[0040] It should be noted that the tool holder in this embodiment can be a T30 tool holder, and the tool holder can be detachably connected to the floating chamfering head. The floating chamfering head is connected to the robotic arm, and the floating chamfering head is used to achieve adaptive floating adjustment of the height of the steel plate edge to prevent the tool from getting stuck. Alternatively, according to the different heights of the steel plate edge, the height of different edges of the steel plate can first be determined by a vision detection device, and during the chamfering process, the robotic arm adjusts the height of the chamfering head according to the position of the vision detection to control the raising and lowering of the chamfering head to follow the undulation of the steel plate.

[0041] The inventors of this invention, through analysis of existing automatic chamfering equipment, discovered that a major reason for the low efficiency of such equipment is that most of the chamfering cutters used are forming cutters. This means that the height between the blades must match the thickness of the steel plate being chamfered. However, the types of steel plates requiring chamfering are diverse, with varying thicknesses, sometimes significantly different. This necessitates changing the chamfering cutters according to the different plate thicknesses, leading to frequent machine downtime. While steel plates of different thicknesses can be chamfered in batches according to thickness to maintain efficiency, the increasing customization of products and the more demanding processing requirements of different types of steel plates mean that batch chamfering according to thickness is no longer suitable for the processing needs of modern intelligent production lines.

[0042] Therefore, in this embodiment, the lifting base 3, in conjunction with the elastic element 4 and the upper cutter holder 5, allows the lifting base 3 to drive the upper cutter holder 5 to rise and fall relative to the lower cutter holder 6. During chamfering operations, an actuator, such as a robotic arm or a moving gantry, moves the chamfering cutter head above the edge of the steel plate, placing the lower cutter holder 6 on the outer side of the steel plate edge. Then, the actuator moves the cutter head vertically downward until the bottom surface of the pressure plate 7 contacts the top surface of the steel plate edge. At this point, both the upper cutter holder 5 and the lower cutter holder 6 are on the outer side of the steel plate edge. The actuator continues to drive the pressure plate 7 downward, causing the elastic element 4 to deform. This causes the pressure plate 7 to move both the lifting base 3 and the upper cutter holder 5 upward, while the base shaft 1 moves the lower cutter holder 6 downward, continuously increasing the distance between the upper cutter holder 5 and the lower cutter holder 6. When the actuator moves the lower cutter holder 6 downward to a set height, the upper cutter 51 and the lower cutter holder 6... When the distance between the blades 61 exceeds the thickness of the steel plate, the chamfering head drives the base shaft 1 to rotate, causing the spline 14 to drive the lifting base 3 and the upper blade holder 5 below it to rotate. The lower blade holder 6 is also driven to rotate by the base shaft 1, causing multiple upper blades 51 and multiple lower blades 61 to rotate. Then, the actuator moves the base shaft 1 horizontally towards the steel plate and raises the base shaft 1 to a set height. Under the downward pushing force of the elastic element 4, the lifting base 3 drives the upper blade holder 5 to move downward, and the pressure plate 7 positions the multiple upper blades 51 at a certain height, so that the multiple upper blades 51 of the upper blade holder 5 and the multiple lower blades 61 of the lower blade holder 6 clamp the steel plate. At this time, the upper blades 51 and the lower blades 61 chamfer the upper and lower edges of the steel plate respectively. Then, the actuator keeps the base shaft 1 at the current height and moves along the edge of the steel plate, thereby performing chamfering operations on all edges of the steel plate.

[0043] In this way, through the cooperation of the elastic element 4, the lifting base 3, the upper blade holder 5, and the pressure plate 7, the upper blade holder 5 and the lower blade holder 6 are automatically opened and closed. In particular, the elastic element 4 pushes the lifting base 3 downward, so that the pressure plate 7 always keeps in contact with the top surface of the steel plate, thereby positioning multiple upper blades 51. The actuator controls the lifting height of the base shaft 1, so that multiple lower blades 61 of the lower blade holder 6 always keep in contact with the bottom surface of the steel plate. This realizes the automatic adjustment of the distance between the upper blade holder 5 and the lower blade holder 6 according to the different thicknesses of the steel plate. It enables the chamfering operation of various steel plates with different thicknesses with only one blade, without the need to disassemble and replace different chamfering blades according to different steel plate thicknesses. This greatly reduces the downtime of the chamfering equipment and ensures the chamfering efficiency of the automatic chamfering equipment.

[0044] See Figures 1 to 4 Furthermore, the lifting base 3 has a first through hole 31, and the side wall of the first through hole 31 has a spline 14 groove. The spline 14 is located on the side wall of the base shaft 1. The base is inserted into the first through hole 31, and the spline 14 groove is used for transmission connection with the spline 14.

[0048] The first eaves 12 here can be a shoulder.

[0049] Preferably, the elastic element 4 can be a spring.

[0050] The first concave cavity 33 and the first retaining wall 12 cooperate to limit the movement of the elastic member 4, causing the elastic member 4 to push the lifting base 3 downward.

[0052] See Figures 1 to 4Furthermore, the chamfered cutter head also includes a support member 8, which is a rotating body structure with a second recessed cavity 81 on its top surface facing downwards.

[0057] A first bearing 92 is provided in the third through hole 91. The first bearing 92 is used to rotatably connect the connecting base 9 and the base shaft 1.

[0058] The connecting base 9 extends from the bottom end of the base shaft 1 and is threadedly connected to the fixing nut 11, thereby allowing the connecting base 9 to be detached from the bottom end of the base shaft 1. Then the support member 8 is removed.

[0059] The connecting base 9 and the support member 8 can be detachably connected by setting a retaining structure at the edge of the connecting base 9 and the support member 8 respectively, and using a threaded connector to detachably connect the retaining structure.

[0060] Furthermore, by utilizing the first bearing 92, the connecting base 9 is ensured to rotate relative to the base shaft 1, allowing the support member 8 to rotate relative to the base shaft 1 during the clamping of the steel plate.

[0061] See Figures 1 to 4 Furthermore, the side wall of the support member 8 is provided with a plurality of chip removal holes 83, which are connected to the second cavity 81.
