Description

Technical Field

[0001] This utility model relates to the field of plastic sheet machining equipment technology, specifically to a high-efficiency drilling device for plastic sheets. Background Technology

[0002] Drilling is a step in the machining process of plastic sheets, usually done using a drilling machine. During drilling, a fixture is used to clamp and position the plastic sheet. Improvements are being made to enhance versatility and convenience, aiming for efficient processing.

[0003] For example, CN 221697169 U discloses a hollow plastic sheet drilling device that facilitates positioning. It utilizes an electric push rod, handwheel, bidirectional threaded rod, first limiting clamp, and second limiting clamp. During use, the electric push rod is adjusted to a suitable position, and then the handwheel is rotated to drive the bidirectional threaded rod, first limiting clamp, and second limiting clamp, causing them to move towards each other and clamp the hollow plastic sheet, facilitating the fixing of hollow plastic sheets of different sizes. However, the following problem still exists: for hollow plastic sheets, which are generally quite thick, fixing only at both ends makes it difficult to prevent hole displacement during drilling, affecting the drilling quality. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency drilling device for plastic sheets that has a reasonable structure and reliable operation, which solves the above-mentioned problems, avoids deviation during drilling, ensures the straightness of the hole, and improves the drilling quality.

[0005] The technical solution of this utility model is: A high-efficiency drilling device for plastic sheets includes a base plate and a support platform located in the middle of the upper surface of the base plate. The key technical features are: two Z-axis guide frames symmetrically arranged on both sides of the support platform on the base plate; a lifting seat is provided on each Z-axis guide frame; two X-axis electric push rods are spaced apart along the Y-axis on each lifting seat; the telescopic rod ends of the two X-axis electric push rods on the same lifting seat are connected to a right-angle positioning plate; the two right-angle positioning plates are arranged opposite each other, with the horizontal section of the right-angle positioning plate located above its vertical section; an annular frame is connected between the two Z-axis guide frames; an XY-axis moving module is fixed to the upper surface of the annular frame; a Z-axis telescopic cylinder is connected to the slider of the XY-axis moving module; a horizontal positioning plate is fixed to the lower end of the cylinder rod of the Z-axis telescopic cylinder; a drilling machine is fixed to the middle of the horizontal positioning plate; a drill sleeve is fitted onto the lower end of the drill rod of the drilling machine; an expansion plate is provided along the upper edge of the drill sleeve; and a compression spring is provided between the edges of the horizontal positioning plate and the expansion plate.

[0006] The aforementioned high-efficiency punching device for plastic sheets includes a Z-axis guide frame that is a portal frame. The two opposite sides of the portal frame are respectively provided with Z-axis guide rails. The lifting seat is provided with guide grooves that cooperate with the Z-axis guide rails. A lifting cylinder is fixed in the middle of the top surface of the portal frame. The lower end of the cylinder rod of the lifting cylinder is connected and fixed to the upper surface of the lifting seat.

[0007] In the aforementioned high-efficiency punching device for plastic sheets, a rubber pad is fixed to the lower surface of the horizontal section of the right-angle positioning plate.

[0008] In the aforementioned high-efficiency drilling device for plastic sheets, the support platform is a hollow platform with an open upper surface to facilitate drilling.

[0009] The beneficial effects of this utility model are: During drilling, the drilling machine is started, causing the drill rod to rotate. At the same time, the cylinder rod of the Z-axis telescopic cylinder continues to extend downwards, thus drilling a hole in the plastic sheet. Simultaneously, the horizontal positioning plate moves downwards and presses the drill sleeve with a compression spring. The drill rod moves downwards along the drill sleeve, preventing the hole position from shifting and ensuring drilling quality. Attached Figure Description

[0012] The present invention will be described in detail with reference to the accompanying drawings.

[0013] like Figures 1-3 As shown, the high-efficiency drilling device for plastic sheets includes a base plate 17 and a support platform 18 located in the middle of the upper surface of the base plate 17. The base plate 17 has two Z-direction guide frames 1 symmetrically arranged on both sides of the support platform 18. The support platform 18 is a hollow platform with an open upper surface to facilitate drilling.

[0014] The Z-axis guide frame 1 is equipped with a lifting seat 16. The lifting seat 16 has two X-axis electric push rods 14 spaced apart along the Y-axis. The telescopic ends of the two X-axis electric push rods 14 on the same lifting seat 16 are connected to a right-angle positioning plate 13. The two right-angle positioning plates 13 are arranged opposite each other, with the horizontal section of the right-angle positioning plate 13 located above its vertical section. In this embodiment, a rubber pad 12 is fixed to the lower surface of the horizontal section of the right-angle positioning plate 13. The Z-axis guide frame 1 is a portal frame. Z-axis guide rails 15 are respectively provided on the opposite sides of the two side walls of the portal frame. The lifting seat 16 has guide grooves that cooperate with the Z-axis guide rails 15. A lifting cylinder 2 is fixed to the center of the top surface of the portal frame, and the lower end of the cylinder rod of the lifting cylinder 2 is connected and fixed to the upper surface of the lifting seat 16.

[0015] A ring-shaped frame 3 is connected between the top surfaces of two Z-axis guide frames 1. An XY-axis moving module 4 is fixed to the upper surface of the ring-shaped frame 3. A Z-axis telescopic cylinder 5 is connected to the slider of the XY-axis moving module 4. A horizontal positioning plate 6 is fixed to the lower end of the cylinder rod of the Z-axis telescopic cylinder 5. A drilling machine 7 is fixed to the middle of the horizontal positioning plate 6. A drill sleeve 10 is fitted to the lower end of the drill rod 9 of the drilling machine 7. An expansion plate 19 is provided along the upper edge of the drill sleeve 10. A compression spring 8 is provided between the edges of the horizontal positioning plate 6 and the expansion plate 19.

[0016] Working principle: 1. In use, place the plastic plate 11 to be drilled on the support platform 18. Then, the telescopic rods of the X-direction electric push rods 14 on the two lifting seats 16 move relative to each other, and the vertical sections of the two right-angle positioning plates 13 move relative to each other and push to correct the position of the plastic plate. The two lifting seats 16 move downward under the action of the lifting cylinder 2, so that the horizontal sections of the two right-angle positioning plates 13 press down on the edge of the plastic plate 11 to achieve clamping and positioning of the plastic plate 11.

[0017] 2. Start the XY-axis moving module 4, which will drive the Z-axis telescopic cylinder 5, the drilling machine 7 and the drill rod 9 to the position above the pre-drilling position of the plastic plate 11.

[0018] 3. Start the Z-axis telescopic cylinder 5 to drive the drilling machine 7 and drill rod 9 downward, so that the lower end of the drill rod 9 and the lower end face of the drill sleeve 10 simultaneously come into contact with the upper surface of the plastic plate 11.

[0019] 4. Start the drilling machine 7, which drives the drill rod 9 to rotate. At the same time, the cylinder rod of the Z-axis telescopic cylinder 5 continues to extend downward to drill holes in the plastic plate 11. Simultaneously, the horizontal positioning plate 6 moves downward and presses the drill sleeve through the compression spring 8. The drill rod 9 moves downward along the drill sleeve 10, preventing the hole position from shifting and ensuring the drilling quality.

[0020] 5. After completing one hole, the Z-axis telescopic cylinder 5 drives the component below it to reset, and the XY-axis moving module 4 drives the Z-axis telescopic cylinder 5, the drilling machine 7 and the drill rod 9 to move above another pre-drilled position on the plastic plate 11. Then the above operation is repeated to complete the drilling.

[0021] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this utility model.
