Description

Technical Field

[0001] This utility model relates to the field of pipe processing technology, and in particular to a pipe end drilling device. Background Technology

[0002] Pipes are tubular materials with hollow cross sections used for transporting fluids, conveying solid materials, or serving as structural supports. They are applied in construction, municipal engineering, industry, agriculture, and water conservancy. They are classified in various ways, and their performance characteristics are closely related to their application scenarios. When processing and drilling pipes, drilling equipment is required.

[0003] Existing drilling equipment suffers from a narrow range of pipe compatibility and insufficient flexibility, resulting in poor material compatibility. High-speed steel drill bits used for drilling metal pipes can easily tear plastic pipes, while thermoplastic drill bits designed for plastic pipes are ineffective for metal pipes. Multiple sets of equipment are required. The current solution is to integrate an automatic tool changer system, which automatically switches drill bits according to the pipe material (metal, plastic, or composite material), such as high-speed steel drill bits for metal and polycrystalline diamond drill bits for plastic, reducing switching time. However, the pipe still needs to be manually measured and marked for hole positions, and the pipe position needs to be adjusted. For pipes with multiple holes, multiple positioning is required, resulting in large cumulative errors and reducing the working efficiency of the equipment. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Reference Figure 1 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a pipe end punching device, including a frame 1, punching mechanism 2 is provided on both the left and right sides of the top wall of the frame 1, the punching mechanism 2 is used to improve punching efficiency, and a conveying mechanism 3 is provided in the middle of the top wall of the frame 1, the conveying mechanism 3 is used to improve automated conveying efficiency.

[0028] The punching mechanism 2 includes two sliding seats 201. The bottoms of the two sliding seats 201 are fixedly connected to the left and right sides of the top wall of the frame 1, respectively. Multiple mounting plates 202 are fixedly connected at equal intervals on the opposite sides of the top of the two sliding seats 201. The mounting plates 202 can be used to fix the cylinder 203. The cylinder 203 is fixedly installed on one side of the mounting plate 202. A three-jaw chuck 204 is fixedly installed inside the cylinder 203. The three-jaw chuck 204 can achieve the effect of front-side inward displacement when driven. Multiple punches 205 are fixedly connected to the inner wall of the three-jaw chuck 204, so that the front displacement of the three-jaw chuck 204 can drive it. The punch 205 punches holes in the pipe. A clamping post 208 is fixedly connected to the middle of the inner wall of the cylinder 203. Two cylinders 206 are fixedly connected to the top front side of the inner wall of the frame 1. A toothed plate 207 is fixedly connected to the rear end of the cylinder 206. Driven by the cylinder 206, the toothed plate 207 can move horizontally, thereby driving the three-jaw chuck 204. Then, the three-jaw chuck 204 and the punch 205 complete the piercing work. The top wall of the toothed plate 207 is engaged with the three-jaw chuck 204. Adjustment components 210 are provided on both the left and right sides of the middle of the frame 1. Limiting components 211 are provided on the front and rear sides of the bottom wall of the two sliding seats 201.

[0029] The adjustment assembly 210 includes multiple electric push rods 2101. The adjacent sides of the multiple electric push rods 2101 are respectively fixedly connected to the left and right sides of the middle part of the frame 1. One end of the electric push rod 2101 is fixedly connected to a fixing plate 2102, so that when the electric push rod 2101 is activated, the fixing plate 2102 can drive the sliding seat 201 to move horizontally, thereby achieving the purpose of engaging the pipe with the clamping post 208. The tops of the multiple fixing plates 2102 are respectively fixedly connected to the bottoms of the corresponding sliding seats 201. The horizontal heights of the two sliding seats 201 are the same, and the multiple cylinders 203 are arranged symmetrically at equal intervals.

[0030] Specifically, in the drilling mechanism 2 on the left and right sides of the top wall of frame 1, two sliding seats 201 are slidably connected to the bottom of the top wall of frame 1. Multiple mounting plates 202 on opposite sides of the top are fixed with cylinders 203, allowing the cylinders 203 to be installed and connected to the three-jaw chuck 204. Subsequently, multiple punches 205 are fixed to the inner wall of the three-jaw chuck 204, and a locking post 208 is fixed in the middle of the inner wall. Two cylinders 206 at the top front of the inner wall of frame 1 drive the rear gear plate 207 to move horizontally. The top wall of the gear plate 207 meshes with the three-jaw chuck 204, causing the front of the three-jaw chuck 204 to move inward. The punch 205 punches holes in the pipe. In the adjustment components 210 on the left and right sides of the middle of the frame 1, multiple electric push rods 2101 are fixed to the frame 1 on one side. The top of the fixing plate 2102 at one end is fixed to the bottom of the corresponding sliding seat 201. When the electric push rod 2101 is activated, it drives the sliding seat 201 to move horizontally, so that the pipe is engaged with the clamping post 208. The limiting components 211 on the front and rear sides of the bottom wall of the sliding seat 201 assist in limiting. The two sliding seats 201 are at the same horizontal height. Multiple cylinders 203 are arranged symmetrically at equal intervals. The conveying mechanism 3 in the middle of the top wall of the frame 1 improves the automated conveying efficiency and improves the overall punching efficiency.

[0031] Reference Figure 1 Figure 3 and Figure 5 The conveying mechanism 3 includes a dual-axis motor 301. The bottom of the dual-axis motor 301 is fixedly connected to the front side of the middle of the top wall of the frame 1, so that multiple drive tooth plates 302 can rotate under the drive of the dual-axis motor 301. Then, under the connection of the chain 303 and the connecting plate 304, the automatic conveying of the pipe can be completed. The front and rear sides of the top wall of the frame 1 are fixedly connected to the limiting disk 307. The rear limiting disk 307 is rotatably connected to the rotating shaft 305. The output end of the dual-axis motor 301 and both ends of the rotating shaft 305 are fixedly connected to the drive tooth plates 302. Then, under the connection of the limiting disk 307, the rotating shaft 305 can be supported, thereby completing the effect of connecting the two rear drive tooth plates 302, achieving the purpose of automatic conveying and reducing manual operation. The outer walls of multiple drive tooth plates 302 are provided with chains 303. Multiple connecting plates 304 are fixedly connected to the opposite side of the two chains 303. The middle of the top wall of the frame 1 is provided with a support component 306.

[0032] Specifically, the dual-axis motor 301 fixed at the front of the middle of the top wall of frame 1 is started, causing multiple drive gear plates 302 at its output end and both ends of the rotating shaft 305 to rotate. The rotating shaft 305 is rotatably connected to the interior of the rear limiting plate 307 of the top wall of frame 1. The front and rear limiting plates 307 support the rotating shaft 305 and connect the two rear drive gear plates 302. The chains 303 on the outer wall of the multiple drive gear plates 302 rotate with it. Multiple connecting plates 304 fixed on one side away from the two chains 303 move synchronously to complete the automated conveying of the pipe fittings, reducing manual operation. The support component 306 in the middle of the top wall of frame 1 assists in supporting the pipe fittings.

[0033] Reference Figure 2 , Figure 4 and Figure 6 The limiting component 211 includes multiple limiting plates 2111, the top walls of which are fixedly connected to the front and rear sides of the bottom wall of the corresponding sliding seat 201. Two limiting grooves 2112 are opened on the left and right sides of the top wall of the frame 1, and the bottoms of the multiple limiting plates 2111 are slidably connected to the corresponding limiting grooves 2112. The support component 306 includes a support base 3061, the bottom of which is fixedly connected to the middle of the top wall of the frame 1. A top plate 3063 is fixedly connected to the rear side of the support base 3061, and a connecting seat 3062 is fixedly connected to the rear side of the top plate 3063. A control switch 4 is fixedly connected to the front side of the frame 1. The control switch 4 is electrically connected to the cylinder 206, the electric push rod 2101, and the dual-axis motor 301.

[0034] Specifically, the sliding connection between the limiting plate 2111 and the limiting groove 2112 improves the stability of the sliding seat 201 during sliding. The support seat 3061 and the top plate 3063 provide auxiliary support for the pipe fitting, improving the stability during conveying. The control switch 4, which is electrically connected to the cylinder 206, the electric push rod 2101, and the dual-axis motor 301, enables the control switch 4 to open and close the equipment.

[0035] Reference Figure 3 , Figure 4 and Figure 6 The punching mechanism 2 also includes multiple rectangular slots 209, which are equidistantly opened on the outer wall of the corresponding card posts 208; two mounting seats 5 are fixedly connected to the left and right sides of the frame 1, and mounting holes 6 are opened on the top wall of the multiple mounting seats 5; the conveying mechanism 3 also includes multiple reinforcing plates 308, and the top of the multiple reinforcing plates 308 is fixedly connected to the middle of the bottom wall of the frame 1.

[0036] Specifically, multiple rectangular slots 209 protect the end of the punch 205 during displacement and punching, preventing contact damage between the outer wall of the locking post 208 and the punch 205. The connection between the mounting base 5 and the mounting hole 6 allows for flexible fixing of the device, thereby increasing the overall stability of the device during operation. The reinforcing plate 308 provides auxiliary support for the middle part of the frame 1, thereby improving the compressive strength of the middle part of the frame 1.

[0037] Working principle: By adjusting the start of component 210, the sliding seat 201 moves along with multiple multi-functional cylinders 203, allowing the locking pin 208 to engage with the end of the pipe for positioning. Then, with the start of cylinder 206, the toothed plate 207 fixed at the rear end moves horizontally. Because the top wall of the toothed plate 207 meshes with the three-jaw chuck 204, it causes one side of the three-jaw chuck 204 to retract inwards. Multiple punches 205 fixed to the inner wall of the three-jaw chuck 204 move accordingly, impacting the end of the pipe. During the drilling operation, multiple mounting plates 202 on the opposite side of the top of the sliding seat 201 fix the cylinder 203, ensuring that the cylinders 203 are symmetrically arranged at equal intervals and that the two sliding seats 201 are at the same horizontal height. The limiting components 211 on the front and rear sides of the bottom wall restrict the displacement trajectory of the sliding seat 201. After the drilling is completed, the adjusting component 210 drives the sliding seat 201 and related components to return to their positions, avoiding large cumulative errors in multi-hole pipes due to multiple positioning. The conveying mechanism 3 in the middle of the top wall of the frame 1 assists in automated conveying, improving the overall drilling efficiency.

[0038] Furthermore, by starting the dual-axis motor 301, its output end drives the fixed drive tooth plate 302 to rotate. In the limiting disks 307 fixed on the front and rear sides of the top wall of the frame 1, the rear drive tooth plate 302 rotates synchronously with the rotating shaft 305 via the chain 303. The limiting disk 307 supports the rotating shaft 305, ensuring the stable rotation of the two rear drive tooth plates 302. The chains 303 set on the outer walls of the multiple drive tooth plates 302 rotate cyclically under the drive of the drive tooth plates 302. The multiple connecting plates 304 fixed on the side away from the two chains 303 move synchronously with the chains 303, realizing the automated conveying of pipe materials and reducing manual operation. The support component 306 in the middle of the top wall of the frame 1 plays an auxiliary support role for the pipes during the conveying process, ensuring the stability during conveying, and improving the overall conveying and drilling efficiency in conjunction with the drilling mechanism 2.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
