DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] A punching device for a wooden ruler, such as Figure 1 As shown, it includes a base 1, a drill arm 2, a handwheel 3, a drill bit 4, a placement table 5 and an indicating mechanism 6. The drill arm 2 is connected to the upper right side of the base 1, the handwheel 3 is rotatably connected to the upper front side of the drill arm 2, the drill bit 4 is provided on the upper left side of the drill arm 2, the placement table 5 is connected to the upper left side of the base 1, a travel hole is opened on the placement table 5, and an indicating mechanism 6 is provided on the top of the base 1.
[0018] like Figure 1 and Figure 2As shown, the indicating mechanism 6 includes a fixed seat 60, a rotating frame 61, an indicating block 62, a positioning column 63 and a spring 64. The top of the base 1 is connected to the fixed seat 60, the rotating frame 61 is rotatably connected to the fixed seat 60, the lower left side of the rotating frame 61 is connected to the indicating block 62, the center of the indicating block 62 is aligned with the center of the drill bit 4, the upper right part of the fixed seat 60 is slidably connected to the positioning column 63, and a spring 64 is connected between the positioning column 63 and the fixed seat 60.
[0019] like Figure 1 and Figure 2 As shown, it also includes a fixing mechanism 7, which includes an adjusting screw 70, a connecting frame 71 and a rubber pad 72. The upper left sides of the front and rear parts of the base 1 are rotatably connected with the adjusting screw 70, and the tops of the adjusting screws 70 are provided with knobs. The connecting frames 71 are threadedly connected between the adjusting screws 70, and the lower middle side of the connecting frame 71 is connected to the rubber pad 72.
[0020] When the utility model is in use, the rotating frame 61 drives the indicating block 62 to move below the drill bit 4. The positioning column 63 forms a blocking position for the rotating frame 61 under the action of the spring 64, indicating that the rotating frame has been rotated to the right position. Then, the drilling position of the wooden ruler is moved to the bottom of the indicating block 62, which is convenient for the drill bit 4 to drill downward. After the alignment of the wooden ruler is completed, the adjusting screw 70 is rotated to make the connecting frame 71 drive the rubber pad 72 to move downward to press and fix the wooden ruler to prevent the wooden ruler from shifting. Then, the positioning column 63 is pulled out, and the rotating frame 61 is rotated and removed. After the rotating frame 61 drives the indicating block 62 to move away, the drill bit 4 is started and the hand wheel 3 is rotated again. The hand wheel 3 controls the drill bit 4 to move downward through the drilling arm 2 to perform a drilling operation on the wooden ruler. After the drilling is completed, the drill bit 4 is controlled by the hand wheel 3 to move upward, and the adjusting screw 70 is rotated in the opposite direction to make the connecting frame 71 drive the rubber pad 72 to move upward and separate from the wooden ruler, so that the wooden ruler with the hole drilled can be taken out. The above operation can be repeated to perform a drilling operation on most wooden rulers.
[0021] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
