[0023] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0024] Embodiment one:

[0025] Please refer to Figures 1 to 4 The quick positioning and punching device for the center hole of a stainless steel pipe in the embodiment comprises a workbench 1, two support plates 2 fixedly connected to the top of the workbench 1, a positioning and clamping mechanism arranged between the two support plates 2 for positioning and fixing the stainless steel pipe, an electric push rod 3 fixedly installed on the side of the two support plates 2 opposite to each other, a connecting piece 4 fixedly connected to the output end of the electric push rod 3, positioning and clamping plates 5 arranged at the top and the bottom between the two electric push rods 3, hinged pieces 6 fixedly connected to the front and back of the positioning and clamping plates 5, and a hinged rod 7 hinged between the hinged pieces 6 and the connecting piece 4.

[0026] The shapes of the two positioning and clamping plates 5 are both arc-shaped, and anti-skid pads are fixedly connected to the opposite sides of the two positioning and clamping plates 5. A controller is fixedly installed on the front of the workbench 1, which can control the work of the two electric push rods 3 at the same time.

[0027] It should be noted that when the two electric push rods 3 simultaneously drive the two connecting pieces 4 to move towards each other, the two positioning and clamping plates 5 can move relative to each other, thereby facilitating the positioning and fixing of the stainless steel pipe. At this time, since the two positioning and clamping plates 5 move at the same time, the center position between the two positioning and clamping plates 5 remains in a fixed state, thereby the center point position of the clamped stainless steel pipe remains unchanged regardless of the diameter of the stainless steel pipe.

[0028] In the embodiment, a drive motor 8 is fixedly installed inside the workbench 1. An adjusting lead screw 9 is fixedly connected to the output shaft of the drive motor 8. A threaded sleeve 10 is threadedly connected to the outside of the adjusting lead screw 9. A fixed table 12 is arranged on the top of the workbench 1. A connecting block 11 is fixedly connected between the threaded sleeve 10 and the fixed table 12. A drilling device 13 is fixedly installed on the side of the fixed table 12 away from the workbench 1. The drill bit of the drilling device 13 is aligned with the center position between the two positioning and clamping plates 5.

[0029] The side of the threaded sleeve 10 away from the connecting block 11 is fixedly connected with a limiting block extending into the inside of the workbench 1. A limiting groove matching the limiting block is formed in the inner wall of the workbench 1. Since the two positioning and clamping plates 5 move at the same time, and the stainless steel pipe is usually a cylinder, the center position of the stainless steel pipe remains unchanged regardless of the diameter of the stainless steel pipe. Therefore, the worker only needs to align the drill bit of the drilling device 13 with the center position between the two positioning and clamping plates 5, which is simple to operate and does not require the worker to additionally adjust the drilling device 13.

[0030] The bottom of the workbench 1 is fixedly provided with support legs 18, and the number of the support legs 18 is four.

[0033] In the embodiment, the workbench 1 is fixedly provided with a dust suction fan 17 on the side close to the scrap collecting box 14, one end of the dust suction fan 17 is communicated with the scrap collecting box 14, and the dust suction fan 17 is fixedly connected with a filter screen on the end close to the scrap collecting box 14.

[0034] By adopting the above technical scheme, when the drilling device 13 drills the stainless steel pipe, the generated scrap can be collected through the setting of the collecting hopper 15, and the generated scrap during drilling can be collected through the setting of the dust suction fan 17 and the scrap collecting box 14, thereby reducing the workload of the workers.

[0035] The working principle of the above embodiment is as follows:

[0036] First, the stainless steel pipe to be drilled is placed between the two positioning clamping plates 5, at this time, the two electric push rods 3 are started to drive the two connecting pieces 4 to move towards each other, and then the two positioning clamping plates 5 clamp and fix the stainless steel pipe, after the fixing is completed, the driving motor 8 and the drilling device 13 are started, on the one hand, the drilling device 13 drills the stainless steel pipe, on the other hand, the worker controls the driving motor 8 to make the drilling device 13 process the appropriate depth of the stainless steel pipe, and at the same time, the dust suction fan 17 is started to collect the generated scrap during drilling.

[0037] The electrical components appearing in the text are electrically connected with the main controller and the power supply, the main controller can be a conventional known device such as a computer for control, and the existing disclosed power connection technology is not described herein.
