Description

Technical Field

[0001] This utility model relates to the field of air conditioner grille processing technology, specifically to an air conditioner grille precision hole-opening device. Background Technology

[0002] An air conditioning grille typically refers to a ventilation device installed at the air outlet or return air inlet of an air conditioner. Its main function is to regulate the direction and flow of air, ensuring uniform distribution of indoor air. The grille can be fixed or adjustable, allowing users to adjust the airflow and direction as needed to improve comfort and energy efficiency. As an important protective component for the outdoor or indoor unit of an air conditioner, the surface of the air conditioning grille usually needs to have multiple ventilation holes or mounting holes to meet the heat dissipation and assembly requirements of the air conditioner. Based on the patent search and the shortcomings of existing technologies, the following was found: In existing technologies, most rely on manual hand-held marking tools for positioning, followed by drilling equipment for hole making. Manual operation has a large margin of error, which can easily lead to hole position deviation. This not only affects the appearance quality of the air conditioning grille, but may also cause subsequent assembly difficulties and reduce the product qualification rate. Utility Model Content

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.

[0020] like Figure 1-5 As shown, this utility model discloses a precise opening device for air conditioner grilles and provides the following two embodiments: Example 1: A device for precisely opening an air conditioner grille includes a processing table 101. A positioning mechanism 1 is provided above the processing table 101 for positioning the opening position of the air conditioner grille. At the same time, a fine-tuning mechanism 2 is provided inside the positioning mechanism 1 to improve the accuracy of the positioning mechanism 1. A collection mechanism 3 for collecting waste is provided at the bottom of the processing table 101. The positioning mechanism 1 includes a bracket 11 fixedly connected to the processing table 101. The top of the bracket 11 rotatably passes through a variable pitch lead screw 12. Multiple arc-shaped grooves 13 are provided on the outer side of the variable pitch lead screw 12. Multiple evenly distributed moving blocks 14 are provided above the variable pitch lead screw 12. Each of the multiple moving blocks 14 has a locking rod 15 movably installed at its bottom. The multiple locking rods 15 are respectively locked in the corresponding arc-shaped grooves 13. The outer side of the multiple moving blocks 14 is connected by symmetrically distributed limiting rods 16. Both limiting rods 16 are fixedly connected through the bracket 11. A connecting frame 17 is fixedly installed on the outer side of the multiple moving blocks 14. A positioning plate 18 is provided inside the connecting frame 17. Electric push rods 19 are fixedly installed on both sides of the processing table 101. The output end of the electric push rod 19 passes through the processing table 101. A fixing plate 191 is fixedly installed on the output end of the electric push rod 19.

[0021] Example 2 differs from Example 1 in that: the fine-tuning mechanism 2 includes a support plate 21 fixedly connected to the connecting frame 17, and a threaded rod 22 is threaded through the middle of the two support plates 21, which rotate together. The threaded rod 22 is threaded through the positioning plate 18, and a slot 23 is provided at the top of the connecting frame 17.

[0022] The collection mechanism 3 includes a collection trough 31 located on the lower surface of the inner wall of the processing table 101. A push plate 32 is movably mounted inside the collection trough 31, and a pull plate 33 is fixedly installed at the bottom of the push plate 32. The collection trough 31 can collect the waste material after cutting. By pulling the pull plate 32, the push plate 33 can push the waste material out of the collection trough 31, which is convenient for workers to use.

[0023] A symmetrically distributed limiting plate 41 is fixedly installed on the outer side of the fixed plate 191. The limiting plate 41 passes through the processing table 101. By setting the limiting plate 41, the fixed plate 191 is prevented from shifting during movement, thus improving stability.

[0024] One end of the variable pitch lead screw 12 passes through the machining table 101, and a motor 51 is coaxially fixedly installed on one end of the variable pitch lead screw 12. By setting the motor 51, it is convenient to drive the variable pitch lead screw 12 to rotate.

[0025] Symmetrically distributed stabilizing rods 61 are fixedly installed on opposite sides of the two support plates 21. The stabilizing rods 61 penetrate the positioning plate 18. By setting the stabilizing rods 61, the stability of the positioning plate 18 when it moves is improved.

[0026] A worm gear 71 is fixedly provided at one end of the threaded rod 22. A worm 72 is meshed with the outer side of the worm gear 71. The worm 72 is rotatably mounted on the top of the connecting frame 17. By setting the worm gear 71 and the worm 72, the threaded rod 22 can be self-locked to prevent the positioning plate 18 from shifting when it moves.

[0027] Working principle: In actual use, the air conditioner grille to be processed is placed inside the processing table 101. By activating the electric push rod 19, the fixing plate 191 is driven to fix the grille. Then, by activating the motor 51, the variable pitch screw 12 is driven to rotate. The variable pitch screw 12 drives multiple moving blocks 14 to change the overall pitch through the arc groove 13, the clamping rod 15 and the limiting rod 16. The moving blocks 14 drive the positioning plate 18 to move. By adjusting the spacing between the multiple positioning plates 18, the size of the opening required for the grille is determined, which facilitates the subsequent cutting of the grille. By rotating the worm gear 72, the worm wheel 71 is driven to rotate. The worm wheel 71 drives the threaded rod 22 to rotate, thereby realizing the movement of the positioning plate 18, which allows the staff to fine-tune the position of the positioning plate 18 according to different needs. The collection groove 31 can collect the waste material after cutting. By pulling the pull plate 33, the push plate 32 can push the waste material out of the collection groove 31 for the convenience of the staff.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
