[0001] This utility model is an automatic drilling device for stainless steel pipes, belonging to the technical field of stainless steel pipe drilling equipment. Background Technology

[0002] With the increasing popularity of commercial housing, many families have installed burglarproof windows in their apartment buildings. Burglarproof windows refer to a layer of mesh windows with anti-theft and protective functions added to the original windows of a building. In the process of making burglarproof windows, holes need to be drilled in square tubes, then round tubes are inserted into the holes in the square tubes, and finally welded into mesh burglarproof windows.

[0003] Patent No. CN212042737U discloses an automated batch drilling device for stainless steel pipes. This device involves inserting one end of two stainless steel pipes into a receiving cavity and clamping them with a clamping plate. The drilling mechanism then drills holes in the stainless steel pipes. After each hole is drilled, a cylinder moves the stainless steel pipe a set distance, and drilling continues. This ensures consistent hole spacing on the stainless steel pipes, preventing the inability to insert multiple square pipes into a round pipe. The drilling accuracy is high, and drilling two stainless steel pipes simultaneously significantly improves efficiency. However, this device lacks any protective structure to prevent flying debris, making waste collection difficult and increasing subsequent cleaning burden. There is an urgent need for an automated stainless steel pipe drilling device to address these issues. Utility Model Content

Detailed Implementation

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Please see Figures 1-5 This utility model provides a technical solution: an automatic drilling device for stainless steel pipes, including a main body 1, a U-shaped plate 2, and a closing plate 3. The lower front end of the main body 1 is provided with a through groove 13, and a trapezoidal plate 12 is installed on the inner bottom surface of the main body 1. Multiple through grooves 15 are provided on the left and right sides of the main body 1. Two guide grooves 11 are provided on the left and right ends of the upper part of the main body 1. A servo motor 20 is installed on the left side of the U-shaped plate 2, and the output shaft of the servo motor 20 passes through the left wall of the U-shaped plate 2. A lead screw 23 is installed at the end of the output shaft of the servo motor 20. The lower left and right ends of the closing plate 3 are provided with protrusions 30. A handle 31 is fixedly connected to the front end of the closing plate 3. Magnetic blocks 32 are fixedly connected to the left and right ends of the rear side of the closing plate 3. This design solves the problem that the original device did not have any protective structure to block the flying debris, which made it inconvenient to collect waste and increased the subsequent cleaning burden.

[0021] As the first embodiment of this utility model: Support columns 10 are fixedly connected to the four corners of the main housing 1. A waste bin 14 is movably installed on the front side of the main housing 1, and the waste bin 14 is located below the through groove 13. The through groove 13 and the waste bin 14 cooperate to automatically collect drill cuttings, reducing the burden of manual cleaning and improving environmental protection. Multiple through grooves 15 have circular grooves 17 on their front and rear inner walls. First electric push rods 18 are installed inside the multiple circular grooves 17. Clamping plates 16 are installed at the output shaft ends of the multiple first electric push rods 18. The first electric push rods 18 drive the clamping plates 16, which can accommodate stainless steel pipes of different sizes, ensuring that the pipes do not easily shift during drilling.

[0022] The U-shaped plate 2 has a groove 21 on its upper part. A threaded protrusion 22 is threadedly connected to the outside of the lead screw 23. The upper end of the threaded protrusion 22 is slidably connected to the inner wall of the groove 21. The U-shaped plate 2 is installed in the upper middle part of the main housing 1. The servo motor 20 drives the lead screw 23, causing the threaded protrusion 22 to slide along the groove 21, thereby achieving precise control of the drill bit position. A second electric push rod 24 is installed at the lower end of the threaded protrusion 22. A rectangular plate 25 is installed at the lower end of the output shaft of the second electric push rod 24. Multiple electric drill bits 26 are installed at equal intervals below the rectangular plate 25. The multiple electric drill bits 26 work synchronously to complete multi-hole processing in one go. The second electric push rod 24 controls the depth of the drill bit to adapt to different pipe wall thicknesses. There are two sealing plates 3. Multiple protrusions 30 are slidably connected in multiple guide grooves 11. The sealing plates 3 are fixed by magnetic blocks 32 to block flying debris and protect the operator. The handle 31 and the guide grooves 11 are designed to facilitate the quick opening and closing of the sealing plates 3.

[0023] As a second embodiment of this utility model: In use, firstly, multiple stainless steel tubes to be drilled are inserted into multiple through slots 15 on the left side of the main housing 1, so that the left end of the stainless steel tube is located in the through slot 15 on the left side of the main housing 1, and the right end of the stainless steel tube is located in the through slot 15 on the right side of the main housing 1. Then, multiple first electric push rods 18 are activated, and the stainless steel tubes are clamped and fixed by the clamping plate 16. Then, by pulling the handle 31, the two closed plates 3 are closed. It should be noted that the two magnetic blocks 32 set on one of the closed plates 3 have opposite magnetic properties to the two magnetic blocks 32 set on the other closed plate 3. This can keep the closed state of the two closed plates 3 stable. Then, the second... The electric push rod 24 and multiple electric drill bits 26 perform the first drilling on multiple stainless steel pipes. Most of the waste material splashed during drilling is blocked by the inner wall of the main housing 1 and the two sealing plates 3. Under the guidance of the inclined surface of the trapezoidal plate 12, it falls into the waste bin 14 through the through groove 13. After the first drilling is completed, the multiple electric drill bits 26 are reset, the servo motor 20 is started, and the lead screw 23 rotates, so that the threaded protrusion 22 drives the multiple electric drill bits 26 to move a certain distance, and the drilling operation can be performed again. The subsequent drilling steps are the same. As long as the servo motor 20 rotates intermittently and regularly, the drilling spacing can be guaranteed to be the same. The gap between the two sealing plates 3 when they are closed is used to provide space for the translation of the threaded protrusion 22.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
