[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of a preferred embodiment of a stainless steel screen tube device with adjustable aperture provided by this utility model;

[0021] Figure 2 This is a schematic diagram of the clamping assembly in this utility model;

[0022] Figure 3 This is a schematic diagram of the drilling assembly in this utility model;

[0023] Figure 4 This is a schematic diagram of the distance adjustment component of this utility model.

[0024] An adjustable aperture stainless steel screen tube device includes: a base plate 1 and a tube 3. The base plate 1 is provided with an mounting plate 2 and a clamping assembly 4. The mounting plate 2 is provided with multiple sets of drilling assemblies 5 for drilling operations on the tube 3. The mounting plate 2 is provided with a distance adjustment assembly 6, which corresponds to the drilling assembly 5.

[0025] After the pipe 3 is fixed by the clamping assembly 4, the displacement part drives the second positioning plate 42 to push the pipe 3 to perform axial displacement and feed; the drilling assembly 5 controls the punching depth through the second lifting push rod 53, and the conversion seat 56 rotates to switch the punching head 510 to complete the change of hole diameter or hole shape; the transverse push rod 61 links with the parallelogram mechanism to synchronously adjust the spacing of multiple sets of drilling assemblies 5 to achieve equidistant processing of multiple hole positions.

[0026] The clamping assembly 4 includes a first positioning plate 41, a second positioning plate 42, and a displacement part. The first positioning plate 41 is fixedly connected to the base plate 1, and the second positioning plate 42 is slidably connected to the base plate 1. The first positioning plate 41 has a through hole 43. Both the first positioning plate 41 and the second positioning plate 42 are provided with a support pad 44 and a first lifting push rod 45. The end of the first lifting push rod 45 is fixedly connected with a pressing pad 46, which corresponds to the upper and lower parts of the pipe 3, respectively.

[0027] The clamping assembly 4 uses a combination of a fixed end and a sliding end for positioning, and together with the support pad 44, it forms a three-dimensional clamping system. This system can prevent radial displacement of the pipe 3 and avoid surface indentation, thus improving clamping stability.

[0028] The displacement unit includes a drive motor 47, a displacement lead screw 48, and a sliding rod 49. The displacement lead screw 48 is connected to the output end of the drive motor 47. The second positioning plate 42 is sleeved on the displacement lead screw 48 and slidably connected to the sliding rod 49, thereby driving the second positioning plate 42 to move.

[0029] The displacement unit adopts a transmission combination of drive motor 47, displacement screw 48 and sliding rod 49. The movement distance of the second positioning plate 42 is controlled by the screw to realize the axial positioning of the pipe 3.

[0030] The drilling assembly 5 includes a base 51, on which a through groove 52 and a sliding groove 54 are provided. The through groove 52 corresponds to the distance adjustment assembly 6 and is used to allow it to pass through. A second lifting push rod 53 is fixedly connected to the base 51. The output end of the second lifting push rod 53 is fixedly connected to a lifting seat 55. The lifting seat 55 is slidably connected to the sliding groove 54. A drilling part is provided on the lifting seat 55.

[0031] The leftmost drilling assembly 5 is fixed in place, while the remaining drilling assemblies 5 expand and move to the right at equal intervals with the distance adjustment assembly 6. The base 51 and the through groove 52 structure provide a physical channel for the distance adjustment assembly 6, enabling precise displacement of the drilling assembly 5. The structure design of the second lifting push rod 53 driving the lifting seat 55 to move vertically along the sliding groove 54 can adjust the punching depth without changing the overall layout of the equipment, adapting to the penetration requirements of pipes with different wall thicknesses.

[0032] The drilling section includes a conversion seat 56, a rotating component 57, and a locking component 58. The conversion seat 56 is rotatably connected to the rotating component 57. Drilling motors 59 are provided on both sides of the conversion seat 56. A punch head 510 is fixedly connected to the output end of the drilling motor 59, and the punch heads 510 on the two sides of the drilling motor 59 have different specifications.

[0033] The combination structure of the conversion seat 56 and the drilling motors 59 on both sides achieves 180° rotation switching through the rotating component 57, which allows a single station to quickly call up two specifications of punch heads 510, reducing downtime for mold changes; the locking component 58 provides rigid fixation after the conversion seat 56 is rotated into place, ensuring that the punch head 510 does not shift during high-speed stamping; the differentiated specification configuration of the punch heads 510 on both sides, together with the displacement control of the distance adjustment component 6, can complete the combination processing of variable hole diameter / variable hole type in a single clamping.

[0034] The distance adjustment assembly 6 includes a horizontal push rod 61, a guide rod 62, a first rotating shaft 63, and a linkage rod 65. The base 51 is slidably connected to the guide rod 62. A push rod 64 is fixedly connected to the output end of the horizontal push rod 61. The first rotating shaft 63 is fixedly connected to the center position of the through groove 52. The linkage rod 65 is rotatably connected to the first rotating shaft 63. A second rotating shaft 66 is provided at the end of the linkage rod 65 away from the first rotating shaft 63. The linkage rods 65 are rotatably connected to each other through the second rotating shaft 66.

[0035] The distance adjustment component 6 drives the push rod 64 to generate lateral displacement through the lateral push rod 61. Combined with the parallelogram motion mechanism of the first rotating shaft 63 and the linkage rod 65, it realizes the equidistant synchronous adjustment of multiple drilling components 5, ensuring the consistency of the spacing between multiple holes. The rotational connection design of the second rotating shaft 66 at the end of the linkage rod 65 enables multiple linkage rods 65 to form a series transmission system, and the spacing change of all drilling components 5 can be controlled by a single power source.

[0036] The working principle of the adjustable aperture stainless steel screen tube device provided by this utility model is as follows:

[0037] After the pipe 3 is fixed by the clamping assembly 4, the displacement part drives the second positioning plate 42 to push the pipe 3 to perform axial displacement and feed; the drilling assembly 5 controls the punching depth through the second lifting push rod 53, and the conversion seat 56 rotates to switch the punching head 510 to complete the change of hole diameter or hole shape; the transverse push rod 61 links with the parallelogram mechanism to synchronously adjust the spacing of multiple sets of drilling assemblies 5 to achieve equidistant processing of multiple hole positions.

[0038] Compared with related technologies, the adjustable aperture stainless steel screen tube device provided by this utility model has the following advantages:

[0039] The base plate 1 and the clamping assembly 4 form a stable clamping reference, and the displacement part realizes the axial positioning of the pipe 3. Multiple drilling assemblies 5 support synchronous punching, and the conversion seat 56 quickly switches between two specifications of punching heads 510. The linkage rod 65 of the distance adjustment assembly 6 synchronously controls the hole spacing, improves processing efficiency and hole diameter consistency, adapts to different pipe wall thicknesses and complex hole shape requirements, and reduces mold change downtime.
