[0026] In one embodiment, Figures 1 to 4As shown, a PE plastic pipe punching device includes a workbench 1, the bottom of which is fixed with four support columns. Two brackets 2 are vertically installed on the upper end of the workbench 1, and a crossbeam 3 is provided to connect the brackets 2. Two first acting cylinders 4 are installed side by side on the upper end of the crossbeam 3, and a connecting block 10 is installed at the output end of the first acting cylinder 4, and a fixing frame 6 is fixedly installed at the lower end of the connecting block 10. The fixing frame 6 includes a T-shaped slide 601 and a rack 602, and the T-shaped slide 601 and the rack 602 are connected at both ends by a cross arm 603. The upper end surfaces of the T-shaped slide 601 and the rack 602 are fixed with a connecting block 10, and the protruding ends of the T-shaped slide 601 and the rack 602 are slidably installed in the sliding groove 201 of the bracket 2. The sliding groove 201 is vertically opened on the inner wall of the bracket 2, so that the fixing frame 6 slides up and down under the action of the first acting cylinder 4.

[0027] In one embodiment, Figures 1 to 4 As shown, a plurality of drilling assemblies 7 are slidably connected to the fixed frame 6. The drilling assemblies 7 are driven by a servo motor 703 to slide on the fixed frame 6, and each drilling assembly 7 can be independently driven by its own servo motor 703 to move along the fixed frame 6. The drilling assembly 7 includes a slider seat 701, a support arm 702, a servo motor 703, a gear 704, and a rotary motor 707. The slider seat 701 is a ball slider and is slidably connected to the T-shaped slide rail 601. The support arm 702 is fixedly mounted on the upper end of the slider seat 701. The lower end of the other end of the support arm 702 is mounted with a gear 704, which meshes with the rack 602. The gear 704 is mounted on the output shaft of the servo motor 703. The servo motor 703 drives the slider seat 701 to slide on the T-shaped slide rail 601. A rotating motor 707 is installed inside the slider seat 701. A spring chuck 705 is fixedly installed on the protruding end of the rotating motor 707. A drill bit 706 is installed in the spring chuck 705. The rotating motor 707 drives the spring chuck 705 to rotate at high speed, thereby causing the drill bit 706 to rotate at high speed as well, thereby drilling holes in the PE plastic pipe.

[0028] In one embodiment, Figures 1 to 4As shown, a clamping assembly 8 is mounted on the workbench 1. Two sets of clamping assemblies 8 are installed at the positions of the bracket 2, clamping the PE plastic pipe at the front and rear ends. The clamping assembly 8 comprises a third cylinder 801 and a clamping plate 802. One of the third cylinders 801 is vertically mounted at the lower end of the workbench 1, with a clamping plate 802 attached to its upward-extending end. The clamping plate 802 at the lower end supports the PE plastic pipe. Two other third cylinders 801 are horizontally mounted on either side of the bracket 2, with clamping plates 802 attached to their inward-extending ends. Together, these three clamping plates 802 clamp the PE plastic pipe securely. One set of clamping assemblies 8 is installed on each of the two brackets 2, with the third cylinder 801 and clamping plate 802 mounted between the two sets. The third cylinder 801 is mounted in the middle of the workbench 1, at the lower end, with a clamping plate 802 attached to its upward-extending end. The clamping plate 802 has a concave, arc-shaped surface with a rubber anti-slip pad. The friction force for clamping the PE plastic pipe is increased to prevent the PE plastic pipe from rotating under the action of the drill bit.

[0029] In one embodiment, Figures 1 to 4 As shown, a pre-stressing assembly 9 is provided on one side of the drilling assembly 7. The pre-stressing assembly 9 is installed at the front end of the drilling assembly 7. The pre-stressing assembly 9 is installed on the front and rear units of the drilling assembly 7 to prevent the PE plastic pipe from rotating when drilling the PE plastic pipe. The pre-stressing assembly 9 includes a fixed tube 901. One side of the upper end of the fixed tube 901 is installed on one side of the slider seat 701 through a cross bar 902. The lower end of the fixed tube 901 is movably connected with a support rod 903, and a holding block 904 is fixed to the bottom of the support rod 903. A spring 905 is fixedly installed between the top of the holding block 904 and the bottom of the fixed tube 901. There are two groups of pre-stressing assemblies 9, which are respectively installed on the drilling assemblies 7 at both ends. The holding block 904 is a cylindrical rubber rod.

[0030] In one embodiment, Figures 1 to 4 As shown, the front end of the workbench 1 is provided with a limit assembly 5. The limit assembly 5 is installed at the front end of the workbench 1 and can position the end of the PE plastic pipe. The limit assembly 5 includes a limit block 501, a second operating cylinder 502, and a U-shaped bracket 503. The two arms of the U-shaped bracket 503 are horizontally installed at the front end of the workbench 1. The second operating cylinder 502 is installed on the end face of the U-shaped bracket 503. The extended end of the second operating cylinder 502 is fixedly connected to the limit block 501. The limit block 501 has a T-shaped structure. The workbench 1 is provided with a T-slot. The limit block 501 can slide on the T-slot of the workbench 1.

[0031] The operating process of the PE plastic pipe drilling device of the present invention is as follows: During operation, the PE plastic pipe to be drilled is first placed on the clamping plate 802 at the lower end of the clamping assembly 8. The front end of the PE plastic pipe abuts the limit block 501. The second working cylinder 502 is controlled to adjust the position of the limit block 501 according to the location of the PE plastic pipe to be drilled. The third working cylinder 801 is then controlled to push out and clamp the PE plastic pipe. All drilling assemblies 7 are moved to the front end of the fixed frame 6. The front end of the first drilling assembly 7 is equipped with a preloading assembly 9, so that the fixed pipe 901 of the preloading assembly 9 abuts the cross arm 603. The drilling assemblies 7 are then moved to the front end of the fixed frame 6 one by one, and abutted against each other. The drilling assemblies 7 are then moved in sequence according to the drilling location based on the position of the PE plastic pipe. The servo motor 703 is controlled to move the drilling assemblies 7 in order to align them. During drilling, the rotary motor 707 is activated, which drives the spring chuck 705 to rotate at high speed, thereby also rotating the drill bit 706 at high speed. The first cylinder 4 drives the connecting block 10 downward. Under the action of the spring 905, the holding block 904 on the preload assembly 9 contacts the PE plastic tube first. As the first cylinder 4 presses downward, the holding block 904 firmly presses the PE plastic tube. The drill bit 706 continues to move downward until the PE plastic tube is perforated. The first cylinder 4 then retracts, completing the drilling process. The third cylinder 801 on each horizontal axis of the clamping assembly 8 retracts, releasing the clamping plate 802 and removing the PE plastic tube. No position adjustment is required before proceeding to the next piece. This simple operation and simultaneous drilling ensure both precision and efficiency.

[0033] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
