[0022] Example 1

[0023] like Figure 1 and Figure 2 As shown, this embodiment provides a hole-punching device for processing an air-conditioning housing, comprising a workbench 100, a first punching mechanism 200, two pressing mechanisms 300, and a baffle adjusting mechanism 400. The first punching mechanism 200 comprises a first mounting frame 210 fixed on the workbench 100, a first pushing assembly 220 fixed on the first mounting frame 210, and a first punching head 230 fixed at the bottom of the first pushing assembly 220. The workbench 100 is provided with an avoidance hole 110, which is located directly below the first punching head 230. The two pressing mechanisms 300 are fixed on the first mounting frame 210, and are respectively arranged on both sides of the first punching head 230, for lifting and lowering the housing. The baffle adjusting mechanism 400 comprises an adjusting assembly 410 and a limiting plate 420. The adjusting assembly 410 is used to push the limiting plate 420 to translate, and the limiting plate 420 is arranged on the outer side of the first punching head 230. The limiting plate 420 gradually approaches or moves away from the first punching head 230 when moving.

[0024] Push the shell to be punched into the workbench 100 along the limiting plate 420, use the adjustment component 410 to adjust the distance between the limiting plate 420 and the first punching head 230, use the pressing mechanism 300 to press the shell to be punched, and use the first punching head 230 to punch a hole in the shell.

[0025] The first pushing assembly 220 includes a first mounting seat 221, a first limiting seat 222, a first driving source A223 and an electric push rod 224. The first mounting seat 221 and the first limiting seat 222 are both fixed on the first mounting frame 210. The first driving source A223 is fixed on the first mounting seat 221. The electric push rod 224 is connected below the first driving source A223. A limiting hole is opened on the first limiting seat 222, and the electric push rod 224 moves through the limiting hole.

[0026] The electric push rod 224 is driven by the first driving source A223, and the electric push rod 224 drives the first punching head 230 to perform a hole-making operation. The first mounting seat 221 is used to fix the first driving source A223, and the limiting hole on the first limiting seat 222 allows the electric push rod 224 to pass through, so as to prevent the electric push rod 224 from shaking during the activity.

[0027] The first stamping mechanism 200 also includes a first lifting assembly 240, which includes a first support frame 241, a first driving source B242 and a first screw rod 243. The first support frame 241 is fixed on the first mounting frame 210, the first driving source B242 is fixed on the first support frame 241, the first screw rod 243 is arranged below the first driving source B242 and is driven by the first driving source B242, and a first slider 244 is fixed on the first pushing assembly 220, and the first slider 244 moves on the first screw rod 243.

[0028] The first lifting assembly 240 is used to control the height of the first pushing assembly 220, that is, to control the height of the electric push rod 224, thereby controlling the thickness of the opening. The first screw rod 243 is driven by the first driving source B242, and the first screw rod 243 drives the first slider 244, thereby realizing the lifting of the first pushing assembly 220.

[0029] Guide rods 245 are respectively disposed on both sides of the first screw rod 243 . A guide block 225 is fixed on the first pushing assembly 220 . The guide rods 245 pass through the guide block 225 .

[0030] The guide block 225 moves along the guide rod 245 , so that the first pushing assembly 220 is more stable when moving.

[0031] The top end of the first screw rod 243 is connected to the first driving source B242 via a coupling, and the bottom end is mounted on the workbench 100 .

The support base 310 is fixed on the first mounting frame 210, the cylinder 320 is fixed on the support base 310, the telescopic end of the cylinder 320 extends downward from the support base 310, and the pressing block 330 is fixed to the bottom of the telescopic end of the cylinder 320. The two pressing blocks 330 and the first punching head 230 are located on the same straight line.

[0033] There are two groups of adjustment components 410, which are respectively arranged at the two ends of the limit plate 420. The adjustment components 410 include a fixed seat 411 and an adjustment screw 412. The fixed seat 411 is fixed on the workbench 100. A threaded hole is opened on the fixed seat 411.

[0034] The limit plate 420 is arranged below the first limit seat 222, and the adjustment screw 412 is rotated to adjust the distance between the limit plate 420 and the fixed seat 411. When the adjustment degrees of the two adjustment screws 412 are the same, the length direction of the limit plate 420 is parallel to the straight line where the two pressing mechanisms 300 are located, and when the adjustment degrees of the two adjustment screws 412 are different, the limit plate 420 is inclined to the straight line where the two pressing mechanisms 300 are located, so as to adapt to various types of housing openings.
