[0022] The following will be combined with the drawings in the embodiments of the utility model to clarify the technical solutions in the embodiments of the utility model; it is completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides Figure 1 to Figure 6 The hole punching device for aluminum profile processing shown in the figure comprises an operating table 1, an electric push rod 3 is arranged above the operating table 1, a bracket 2 is fixedly connected to the upper surface of the operating table 1, and the electric push rod 3 is fixedly connected to the lower surface of the top of the bracket 2. A motor 4 is fixedly connected to the telescopic end of the electric push rod 3, and a drill bit 5 is fixedly connected to the driving shaft of the motor 4, and the drill bit 5 can be replaced. The electric push rod 3 is used to drive the drill bit 5 to move up and down, and cooperates with the motor 4 to realize the hole punching operation.

[0024] It should be noted that the bracket 2 can also slide on the operating table 1, and the electric push rod 3 can slide on the bracket 2, thereby changing the position of the drill bit 5 to meet the needs of drilling holes at different positions. The position adjustment of the drill bit 5 is an existing common technology and will not be elaborated here.

[0025] In order to prevent waste chips from splashing and improve the stability of the hole-opening operation, a protective tube 6 is provided on the outside of the drill bit 5, a support frame 19 is fixedly connected to the telescopic end of the electric push rod 3, a protrusion 23 is fixedly connected to the outer wall of the protective tube 6, a slide column 20 is fixedly connected to the protrusion 23, and one end of the slide column 20 away from the protrusion 23 is slidably connected to the support frame 19. A spring 21 is sleeved on the outside of the slide column 20, one end of the spring 21 is fixedly connected to the support frame 19, and the other end of the spring 21 is fixedly connected to the protrusion 23.

[0026] During operation, when the protective tube 6 abuts against the aluminum workpiece, the protective tube 6 pushes the slide post 20 to slide upward on the support frame 19 through the protrusion 23, and compresses the spring 21, so that the drill bit 5 can continue to move downward, so as to perform drilling processing on the aluminum workpiece;

[0027] At the same time, since the protective tube 6 surrounds the outer side of the drill bit 5, it can prevent waste chips from flying.

[0028] It should be noted that the protective tube 6 can be made of a transparent material to facilitate operators to observe the internal opening conditions.

[0029] In order to prevent the accumulation of debris in the protective tube 6 and affect the hole opening operation, a first suction chamber 7 is provided inside the wall of the protective tube 6, and the first suction chamber 7 is located in the lower half of the protective tube 6. A circular hole 8 is provided on the lower surface of the protective tube 6, and the circular hole 8 is connected to the first suction chamber 7. There are multiple circular holes 8.

[0031] When the protective cylinder 6 is in contact with the aluminum profile workpiece, the first solenoid valve 11 is opened and the second solenoid valve 14 is closed. The suction device performs negative pressure adsorption on the aluminum profile workpiece through the air pipe 22, the second suction chamber 9, the first suction chamber 7 and the circular hole 8, and then the first solenoid valve 11 is closed to keep the inside of the first suction chamber 7 in a negative pressure state, while the protective cylinder 6 and the aluminum profile workpiece form a whole to prevent the drill bit 5 from shaking during the hole opening operation, thereby improving the accuracy of the hole opening.

[0032] In addition, a sealing ring may be provided at the circular hole 8 to improve the sealing performance.

[0033] During the hole opening operation, the second solenoid valve 14 is opened, and the suction device sucks the debris through the air pipe 22, the second suction chamber 9, the third suction chamber 12 and the suction port 15 to prevent excessive accumulation of waste debris in the protective tube 6 and affect the hole opening operation.

Since the slide plate 18 is slidably arranged inside the slide groove 17, it does not affect the drilling operation of the drill bit 5.

[0036] And can be provided with corresponding ring 16 and slide plate 18 according to drill bit 5 of different sizes. When drill bit 5 needs to be replaced, drill bit 5, ring 16 and slide plate 18 can be integrally extracted from the inside of protective tube 6, and then replaced.
