Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to an aluminum tube opening device. Background Technology

[0002] Aluminum tubes are lightweight and corrosion-resistant metal pipes widely used in various technical fields. To facilitate the connection and fixation of aluminum tubes and make them suitable for various industrial and construction applications, it is often necessary to drill holes in the aluminum tubes.

[0003] In the prior art, a device for opening holes on the surface of an aluminum tube is disclosed, with document number CN215279978U.

[0004] The device includes a body with a base at its lower end, which is fixedly connected to the body by welding. A drill bit is located on one side of the body and is fixedly connected to the body by rotation. A limit strip is located on one side of the body, and a drilling pressure rod is fixedly connected to the upper side of the body by rotation. This invention adds an automatic clamping device to the original design. In use, when the aluminum tube is placed inside the drilling table, it contacts two No. 2 fixing plates. The aluminum tube itself has a certain weight, and its own weight causes the No. 2 fixing plates to expand outward. Gravity causes the No. 2 fixing plates and the No. 2 rotating shaft to slide inward through the limit shaft and the sliding groove, clamping the aluminum tube. During drilling, the drill bit also has downward pressure, making it more stable.

[0005] However, in the above solution, the automatic clamping device for positioning the aluminum tube, the first fixing plate, and the second fixing plate are all clamped on the outer surface of the aluminum tube. When drilling a hole in the aluminum tube, the aluminum tube needs to withstand a certain pressure, which can easily lead to localized deformation at the drilling site. Summary of the Invention

[0006] To solve the above problems, this utility model provides an aluminum tube opening device that prevents local deformation of the aluminum tube during processing.

[0007] To achieve the above objectives, the technical solution of this utility model is: an aluminum tube drilling device, including an operating platform, on which a fixing component and a drilling component are provided. The fixing component includes a central column, which is connected to the operating platform via a vertical column. The central column includes three parts: a column starting section, a column middle section, and a column ending section, which are connected sequentially.

[0008] An internal support assembly is provided on the middle section of the column. After the aluminum tube to be processed is sleeved on the central column, the internal support assembly is adjusted to apply an internal support force to the inner wall of the aluminum tube to be processed.

[0009] The column has a through hole extending along its length at the center of the middle section, and several through holes on the side of the middle section. The inner support assembly includes a limiting arm that is inserted into the through hole. The outer end of the limiting arm is connected to a compression return spring, and the other end of the compression return spring is connected to a support arm. An inner support plate is screwed onto the support arm.

[0010] A horizontal prism is installed inside the through-hole. A pull rope is connected to the inner end of the limiting arm. The pull rope passes through the prism and is connected to an adjustment component. The adjustment component can control the distance between the inner support plate and the middle section of the column.

[0011] Furthermore, the adjustment component includes an adjustment rod, which is screwed to the starting section of the column. An operating disc is connected to the outer end of the adjustment rod, and a spherical groove is provided on the inner circumferential surface of the adjustment rod. A ball is connected to the free end of the traction rope. The ball is fitted into the spherical groove, and the ball can rotate in the spherical groove, but the ball cannot be moved out of the spherical groove.

[0012] Furthermore, a groove is provided on the outer side of the column termination section, and a column is adapted to fit in the groove, with the bottom end of the column connected to the operating platform.

[0013] Furthermore, the operating platform is equipped with a support column, a support plate is connected to the support column, a drive motor is installed on the support plate, and the output shaft of the drive motor is connected to the end section of the column.

[0014] Furthermore, the operating platform is equipped with a slide rail, the length of which is parallel to the length of the central column, allowing the drilling assembly to slide along the length of the slide rail.

[0015] Furthermore, the inner support plate is provided with a strip-shaped notch. When the aluminum tube to be processed is fixed by the fixing component, the position of the strip-shaped notch corresponds to the position of the hole on the aluminum tube.

[0016] Compared with the prior art, the beneficial effects of this utility model are: by setting an internal support component, the internal support plate in the internal support component applies an internal support force to the inner wall of the aluminum tube to be processed to fix the aluminum tube to be processed. The internal support plate is provided with a strip-shaped notch. During assembly, the strip-shaped notch corresponds to the position of the hole to be processed on the aluminum tube to be processed, which can prevent the aluminum tube from deforming when the drilling device makes a hole in the aluminum tube.

[0017] In addition, a drive motor is connected to the end of the central column, which can control the rotation of the aluminum tube to be processed, thereby facilitating the processing of different holes in the aluminum tube. Attached Figure Description

[0028] See Figures 1 to 5 As shown, an aluminum tube drilling device includes a connecting operating platform 1. The operating platform 1 is provided with a fixing component and a drilling component 14. The aluminum tube 20 to be processed is placed on the fixing component and can be stably clamped by the fixing component. After the fixing component stably clamps the aluminum tube 20 to be processed, the drilling component 14 can be used to drill holes in the aluminum tube 20.

[0029] The fixed assembly includes a central column 2, which is connected to the operating platform 1 via a column 3. The central column 2 is divided into three parts: a column starting section 201, a column middle section 202, and a column ending section 203. The three parts are connected in sequence. A threaded through hole is provided at the center of the column starting section 201, which extends along the length of the column starting section 201. A through hole is provided at the center of the column middle section 202, which also extends along its length. The diameter of the through hole is larger than the diameter of the threaded through hole, and the two are connected. The free end of the column 3 is connected to the column ending section 203.

[0030] An internal support component 4 is provided on the middle section 202 of the column. After the aluminum tube 20 to be processed is placed on the central column 2, the internal support component 4 is adjusted. The internal support component 4 applies an internal support force to the inner wall of the aluminum tube 20 to be processed, so that the position of the aluminum tube 20 remains relatively stable.

[0031] The middle section 202 of the column has several through holes on its side. These through holes are arranged in a circular array around the central axis of the middle section 202. In this invention, preferably, the number of through holes is 4. The inner support assembly 4 includes a limiting arm 401 that passes through these through holes. The outer end of the limiting arm 401 is connected to a compression return spring 402. In the initial state, the compression return spring 402 is in its natural state. The other end of the compression return spring 402 is connected to a support arm 403. An inner support plate 404 is screwed onto the support arm 403. Plate 404 is an arc-shaped strip. The connection point between the support arm 403 and the inner support plate 404 is located at the center of the inner support plate 404. Since the inner support plate 404 has a certain weight, in order to prevent the compression return spring 402 from bending and deforming under the action of the inner support plate 404, a sleeve 405 is sleeved on the compression return spring 402. The inner end of the sleeve 405 is connected to the middle section 402 of the column. The sleeve 405 has a certain limiting effect on the compression return spring 402. The inner support plate 404 is provided with a strip-shaped notch, and different inner support plates 404 can be replaced according to the drilling requirements.

[0032] A prism 5 is installed in the through-hole of the middle section 202 of the column. The prism 5 is horizontal and is connected to the inner wall of the through-hole by a support arm 6. Several wire channels 7 are provided on the prism 5. The inlet of each wire channel 7 is located on the side of the prism 5, and the outlet is located on the bottom surface near the starting section 201. The inner end of the aforementioned limiting arm 401 is connected to a pull rope 8. The free end of the pull rope 8 passes through the wire channel 7 at the corresponding position of the prism 5 and is connected to a pull ring 9. Since there are four limiting arms 401, and each limiting arm 401 is connected to a pull rope 8, the four pull ropes 8 are simultaneously connected to a pull ring 9. A traction rope 10 is connected to the pull ring 9. The free end of the traction rope 10 is provided with a ball bearing 11. The ball bearing 11 is connected to an adjustment component, which can control the distance between the inner support plate and the middle section of the column.

[0033] The adjustment assembly includes an adjustment rod 12 with external threads. The adjustment rod 12 is screwed onto the column starting section 201. An operating disc 13 is connected to the outer end of the adjustment rod 12. A spherical groove is provided on the inner circumferential surface of the adjustment rod 12, and a ball bearing 11 is fitted into the spherical groove and can rotate within it. A cap is screwed onto the inner end face of the adjustment rod 12, through which a traction rope can pass. When the cap is in contact with the inner end face of the adjustment rod 12, the ball bearing 11 cannot be moved out of the spherical groove. Rotating the operating disc 13 moves the adjustment rod 12, along with the pull rope 8, towards the column starting section 201, while the inner support plate 404 moves towards the center column. Moving in the direction of 2, after rotating the operating disk 13 to move the inner support plate 404 toward the direction of the central column 2, the aluminum tube 20 is fitted onto the central column 2, and the position of the strip notch on the inner support plate 404 corresponds to the position of the hole to be drilled in the aluminum tube 20. Rotating the operating disk 13 in the opposite direction, the inner support plate 404 moves toward the direction of the inner wall of the aluminum tube 20 until it contacts the inner wall of the aluminum tube 20 to be processed. The setting of the compression return spring 402 can make the inner support plate 404 contact the inner wall of the aluminum tube 20 to be processed more tightly. After fixing the aluminum tube 20 to be processed using the inner support assembly 4, the drilling assembly 14 can be used to drill the aluminum tube 20.

[0034] The drilling assembly 14 is slidably connected to the operating platform 1. The drilling assembly 14 includes a base, a support column and a drill bit. The operating platform is provided with a slide rail 15 extending along its length direction. The length direction of the slide rail 15 is parallel to the length direction of the central column 2. The base is adapted to the slide rail 15. The base can slide along the length direction of the slide rail 15 and the position of the base can be locked.

[0035] In addition, sometimes it is necessary to process multiple holes in the same aluminum tube 20 at the same time, and these holes are not on the same side of the aluminum tube 20 to be processed. The operating platform 1 is provided with a support column 16, and a support plate 17 is connected to the support column 16. The support plate 17 is provided with a drive motor 18. The output column of the drive motor 18 is fixedly connected to the center of the circumferential surface of the column termination section 203. A sliding groove 19 is provided on the side of the column termination section 203. The free end of the above-mentioned column 3 is adapted to the sliding groove 19. When the drive motor 18 rotates, it can control the rotation of the central column 2, thereby driving the aluminum tube 20 to rotate.

[0036] When using the above-mentioned aluminum tube drilling device, firstly, assemble a suitable inner support plate 404 according to the requirements of the hole position on the aluminum tube 20 to be processed. Then, rotate the operating disk 13 to move the inner support plate 404 towards the direction closer to the central column 2. Then, put the aluminum tube 20 to be processed from the column starting section 201 onto the central column 2. Then, rotate the operating disk 13 in the opposite direction to move the inner support plate 404 towards the direction closer to the inner wall of the aluminum tube 20 until the inner support plate 404 applies an internal support force to the aluminum tube 20. During this process, make the strip notch on the inner support plate 404 correspond to the hole position to be processed on the aluminum tube 20. Finally, start the drilling assembly 14 to perform drilling operation on the aluminum tube 20. When it is necessary to process different hole positions of the aluminum tube 20, the aluminum tube 20 to be processed can be rotated by sliding the drilling assembly 14 or starting the drive motor 18.

[0037] The aforementioned drive motor 18 is a low-speed stepper motor; its function is applied without any structural improvement.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be primarily defined by the scope of the claims.
