Description

Technical Field

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

[0002] In modern industrial production, pipes, as a basic material, are widely used in many fields such as construction, machinery manufacturing, automotive industry, aerospace, and medical devices. As various industries continue to increase their requirements for product quality and performance, more stringent standards have been set for the processing precision and quality of pipes, among which pipe drilling is an extremely critical process.

[0003] A typical pipe drilling device consists of a drilling machine, a support device, and a moving device. The drilling machine is the core component of the entire device. Its internal motor drives the drill bit to rotate at high speed. The sharp edge of the drill bit applies pressure and cutting force to the surface of the pipe, drilling a hole in the pipe through mechanical cutting. The support device mainly serves to stabilize the pipe, providing stable support from below and the sides to ensure that the pipe does not shift or shake during the drilling process. The moving device enables the drilling machine to move smoothly in the axial or radial direction of the pipe.

[0004] In some existing devices, after the pipe is punched, the processed pipe needs to be removed from the device for subsequent processes. However, during this process, the pipe often comes into contact with and scrapes against the moving and supporting structure of the device. Since the pipe is usually coated with a protective coating during the production process, this unavoidable scraping in existing devices can easily damage the original intact outer coating of the pipe. Therefore, a pipe punching device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a pipe drilling device, which aims to improve the problem in the prior art where some devices cause damage to the original external coating by rubbing against the support structure after the pipe is drilled.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A pipe drilling device includes a workbench, a slide rail frame fixedly connected to the top of the workbench, a drilling frame installed inside the slide rail frame, a support mechanism inside the workbench, and a limiting mechanism on the top of the workbench.

With the cooperation of the inner sliding tube, the outer supporting tube, and the telescopic spring assembly, the inner sliding tube can expand and contract according to the change of pipe diameter, thus solving the adaptability problem of pipes with different diameters.

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.

[0032] Reference Figures 1 to 3 The present invention provides an embodiment of a pipe drilling device, comprising a workbench 1, which serves as the basic support structure for the entire device and provides an installation platform. A slide rail frame 2 is fixedly connected to the top of the workbench 1, and the slide rail frame 2 provides a sliding track for a drill frame 3, enabling the drill frame 3 to move along a specific direction to drill holes at different positions on the pipe. The drill frame 3 is installed inside the slide rail frame 2, and the drill frame 3 is equipped with drilling equipment and is responsible for drilling the pipe. A support mechanism 4 is provided inside the workbench 1, and a limiting mechanism 5 is provided on the top of the workbench 1.

[0033] The support mechanism 4 includes an equipment frame 41, which serves as the mounting carrier and protects internal components from external interference. The equipment frame 41 is externally and fixedly connected to the inside of the workbench 1. A top plate 42 is threadedly connected to the top of the equipment frame 41. The top plate 42 cooperates with diagonal bracing plates 43 to provide support for the pipe and guide the sliding of the connecting frame 46. Two diagonal bracing plates 43 are externally and fixedly connected to the top plate 42. The diagonal bracing plates 43 increase the contact area with the pipe, improving the stability of the support. Anti-slip pads 44 are fixedly connected to the top of each of the two diagonal bracing plates 43. The anti-slip pads 44 increase the friction with the pipe surface and prevent slippage. During the support process, the pipe slides. A support frame 45 is slidably connected inside the equipment frame 41. The support frame 45 is equipped with connecting frames 46 and rollers 47, and moves up and down under the action of the drive assembly 49, thereby adjusting the support height. Two connecting frames 46 are fixedly connected to the top of the support frame 45, connecting the support frame 45 and the rollers 47, allowing the rollers 47 to move with the support frame 45. Rollers 47 are rotatably connected to the adjacent sides of the two connecting frames 46. During the upward movement of the support frame 45, the rollers 47 roll along the inner bottom of the inclined support plate 43, assisting in the movement of the pipe. The inner... Two limiting components 48 are fixedly connected to the bottom side of the support frame 41. Each limiting component 48 includes two outer sliding sleeves 481, the bottoms of which are fixedly connected to the inner bottom side of the equipment frame 41. Inner sliding rods 482 are slidably connected to the inner top of each outer sliding sleeve 481. The outer sliding sleeves 481 and inner sliding rods 482 limit the movement of the support frame 45, ensuring its vertical up-and-down movement and preventing it from shifting. A drive component 49 is fixedly connected to the inner bottom side of the equipment frame 41. The drive component 49 includes an air pump 491, which serves as a power source, generating thrust through compressed air. The bottom of the air pump 491 is fixed... Connected to the inner bottom side of the equipment frame 41, the air pump 491 is fixedly connected to the outside of the air pipe 492, which inputs pressurized gas into the air pump 491. The output end of the air pump 491 is fixedly connected to the push rod 493, which moves up or down under the action of the air pump 491, pushing the support frame 45 to move. The tops of the two inner sliding rods 482 are fixedly connected to the bottom of the support frame 45, and the tops of the push rods 493 are fixedly connected to the bottom of the support frame 45. The outside of the two connecting frames 46 are slidably connected to the inside of the top plate 42, and the outside of the rollers 47 are slidably connected to the bottom inside of the two inclined support plates 43.

[0034] Reference Figure 1 , Figure 2 and Figure 4The limiting mechanism 5 includes a base plate 51, which serves as the basic support for the limiting mechanism 5 and is fixed to the top of the workbench 1. The bottom of the base plate 51 is fixedly connected to the top of the workbench 1, and multiple support sleeves 52 are fixedly connected to the top of the base plate 51. The support sleeves 52 provide sliding support for the extension slide rods 53, ensuring that the mounting frame 54 can move up and down smoothly. The extension slide rods 53 are slidably connected inside each of the multiple support sleeves 52. The extension slide rods 53 connect the base plate 51 and the mounting frame 54, allowing the mounting frame 54 to adjust its height as it moves up and down. The mounting frame 54 is fixedly connected to the top of the multiple extension slide rods 53, providing installation and support. A compression spring 55 is fixedly connected to the top of the inside of the mounting frame 54, providing support for the scraper 56 so that it can tightly adhere to the surface of the pipe. The scraper 56 is rotatably connected to the top of the inside of the mounting frame 54, cleaning impurities from the surface of the pipe and ensuring... To ensure drilling quality, two external support tubes 57 are fixedly connected to both sides of the inner side of the mounting frame 54. The external support tubes 57 provide sliding support for the inner sliding tubes 58 and restrict their movement direction. The inner sliding tubes 58 are slidably connected inside the multiple external support tubes 57. The inner sliding tubes 58 are equipped with telescopic spring groups 59 and limiting pulleys 510, and can extend and retract under the action of the telescopic spring groups 59 to adapt to pipes of different diameters. The telescopic spring groups 59 are fixedly connected inside the multiple inner sliding tubes 58. The telescopic spring groups 59 provide elastic force for the extension and retraction of the inner sliding tubes 58, so that the limiting pulleys 510 can fit tightly against the surface of the pipe. The limiting pulleys 510 are rotatably connected to the adjacent side of the two inner sliding tubes 58. The limiting pulleys 510 laterally limit the pipe and reduce the friction between the pipe and the device. The external support of the scraper 56 is on the other end of the compression spring 55. The external sliding connection of multiple support sleeves 52 is slidably connected to the bottom inner side of the mounting frame 54.

[0035] Working principle: When the pipe drilling device is working, the slide rail frame 2 guides the drill frame 3 to move through the internal track. After the drill frame 3 moves into place, the drilling device is turned on and the drill bit rotates at high speed to drill holes. The equipment frame 41 is fixed inside the workbench 1. The top plate 42 is connected to the top of the equipment frame 41 by threads to provide an installation base for the inclined support plate 43. The inclined support plate 43 is fixed to the outside of the top plate 42 in an inclined shape to provide a support point for the pipe. The anti-slip pad 44 on its top prevents the pipe from sliding. Gas is input into the air pump 491 through the air supply pipe 492, which compresses the air to generate power and push the top rod 493 to move up and down, thereby driving the support frame 45 to slide inside the equipment frame 41. The outer sliding sleeve 481 in the limiting component 48 is fixed to the bottom inside the equipment frame 41, and the inner sliding rod 482 slides inside it to ensure that the support frame 45 moves vertically up and down, pushing the connecting frame 46 on its top. Through the connecting frame 46, the roller 47 is driven to lift the drilled pipe away from the inclined support plate 43.

[0036] The base plate 51 is fixed to the top of the workbench 1. When the pipe is lifted and moved, it drives the mounting frame 54 to move upward. The support sleeve 52 is fixed to the top of the base plate 51. The extension slide rod 53 can slide inside to provide guidance for the vertical movement of the mounting frame 54. When the pipe moves, the scraper 56 on the inner side of the top of the mounting frame 54 is supported on the surface of the pipe by the compression spring 55. The outer support tube 57 is fixed to both sides inside the mounting frame 54 to provide a sliding track for the inner sliding tube 58. The inner sliding tube 58 slides in the outer support tube 57 and is telescopically extended by the internal telescopic spring group 59, which is used to install the limiting pulley 510. The telescopic spring group 59 is compressed or stretched when subjected to external force according to the change of pipe diameter, providing telescopic elasticity for the inner sliding tube 58. Under the action of the telescopic spring group 59, the limiting pulley 510 contacts the surface of the pipe and rolls as the pipe moves, thus limiting the pipe laterally.

[0037] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
