[0029] First embodiment:

[0030] This embodiment discloses a container punching device.

[0031] like Figure 1 As shown, the header punching device includes a base 2, a frame 8, a first support 4, a header 3, and a three-axis gantry 1.

[0032] The base 2 is placed on the ground. For example, the base 2 is a cuboid structure.

[0033] A frame 8 is mounted on the first end of the base 2, and a chuck 81 is rotatably mounted on the second end of the frame 8. A first bracket 4 is mounted on the second end of the base 2. A header 3 is horizontally positioned, with an opening 31 at its first end. The inner side of the opening 31 engages with the jaws 811 of the chuck 81, and the second end of the header 3 is engaged with the first bracket 4. For example, the chuck 81 is a commercially available three-jaw chuck 81. Three jaws 811 are radially slidably mounted on the second end of the chuck 81. The three jaws 811 are equally spaced circumferentially around the chuck 81, and can move radially along the chuck 81 to clamp the inner side of the opening 31 of the header 3, thereby fixing the first end of the header 3.

[0034] The three-axis gantry frame 1 is erected on the ground. A motor 11 is fixed on the moving end of the three-axis gantry frame 1. The three-axis gantry frame 1 drives the motor 11 to move along the X, Y, and Z axes. A drill bit 12 is installed on the output end of the lower end of the motor 11. The drill bit 12 is set vertically. The base 2 is located inside the three-axis gantry frame 1. The moving path of the motor 11 passes through the header 3.

[0035] like Figure 2 As shown, further, the first support 4 includes a first vertical plate 42, with a semi-circular groove 421 at the upper end of the first vertical plate 42. First ears 422 are provided at the upper ends of both sides of the first vertical plate 42. A third nut 441 is fixed to one of the first ears 422. A third bolt 442 is screwed into the third nut 441 in a direction perpendicular to the header 3, and the third bolt 442 abuts against the upper end of the side of the header 3 to fix the header 3 to the first support 4. For example, the nut is welded to the first ear 422 and parallel to the length direction of the header 3.

[0036] like Figure 3 and Figure 4 As shown, further, a second support 7 is also provided on the base 2 between the frame 8 and the first support 4. The second support 7 includes a second vertical plate 72 and two pairs of swing assemblies. The two pairs of swing assemblies are symmetrically arranged along the length of the second vertical plate 72. Each pair of swing assemblies includes two swing rods 73 respectively rotatably disposed at the first end and the second end of the second vertical plate 72. The upper ends of the two swing rods 73 of the same swing assembly extend beyond the upper end of the second vertical plate 72, and rollers 74 are rotatably connected between the two swing rods 73. Screws 75 pass through the lower end portion of the swing rod 73 on the side away from the second vertical plate 72 and are threadedly connected to the second vertical plate 72 to fix the swing rods 73. The collection box 3 is supported on the rollers 74 of the two pairs of swing assemblies, and the outer surface of the collection box 3 is tangent to the surface of the two rollers 74. Exemplarily, a first shaft passes through the second vertical plate 72, and its two ends are respectively connected to the two swing rods 73 of the same swing assembly. A second shaft passes through the rollers 74, and its two ends are respectively connected to the upper ends of the two swing rods 73 of the same swing assembly.

[0037] like Figure 3 and Figure 4 As shown, further, an arc-shaped groove 722 with the same center as the pivot axis of the swing arm 73 is formed on the second vertical plate 72. A third shaft is connected between the two swing arms 73 of the same swing assembly, and the third shaft passes through the arc-shaped groove 722. The arc-shaped groove 722 limits the swing angle of the swing arm 73. Several screw holes 721 are formed circumferentially on the second vertical plate 72 with the pivot axis of the swing arm 73 as the center. The positions of the screw holes 721 correspond to the screws 75, so that the swing arm 73 can be fixed at various angles.

[0038] In this embodiment, during use, the operator engages the first end of the header 3 with the jaws 811 of the chuck 81, places the middle of the header 3 between the rollers 74 of the second bracket 7, places the second end of the header 3 in the semi-circular groove 421 of the first bracket 4, and tightens the third bolt 442 to abut against the upper side of the header 3, thus fixing the header 3. The three-axis gantry 1 is started, and the drive motor 11 of the three-axis gantry 1 moves along the X, Y, and Z axes to above the header 3. The motor 11 is started, and its output drives the drill bit 12 to rotate. When it is necessary to drill parallel holes on the header 3, the third bolt 442 is loosened to release the fixation of the second end of the header 3. The frame 8 drives the chuck 81 to rotate, and the chuck 81 rotates the header 3 to a set angle, and the third bolt 442 is then tightened again. The structure is simple, easy to use, and can achieve drilling multiple rows of holes on the outside of the header 3.

[0042] For example, a semi-circular groove 421 is formed at the upper end of the first vertical plate 42, and first ears 422 are provided at the upper ends of both sides of the first vertical plate 42. The semi-circular groove 421 and the first ears 422 form a first clamp. The second clamp 43 includes a semi-circular arc plate 431 and second ears 432 provided at both ends of the semi-circular arc plate 431. The first ears 422 and the second ears 432 are connected by a first fastener 5. For example, the first fastener 5 includes a first bolt 51 and a first nut 52. The first bolt 51 passes through the first ears 422 and the second ears 432 and is bolted to the first nut 52. Preferably, pads are provided between the outer surface of the header 3 and the semi-circular groove 421, and between the outer surface of the header 3 and the semi-circular arc plate 431, to increase the clamping force of the first clamp and the second clamp 43 on the header 3.

[0043] In this embodiment, during use, the operator engages the first end of the header 3 with the jaws 811 of the chuck 81, places the second end of the header 3 inside the first clamp, and fixes the first clamp and the second clamp 43 with the first fixing member 5 to fix the header 3. The three-axis gantry 1 is started, and the drive motor 11 of the three-axis gantry 1 moves along the X, Y, and Z axes to above the header 3. The motor 11 is started, and the output end of the motor 11 drives the drill bit 12 to rotate. When it is necessary to drill parallel holes on the header 3, the second clamp 43 is removed to release the fixation of the second end of the header 3.
