Description

Technical Field

[0001] The utility model belongs to the technical field of wood board processing, and more specifically relates to a drilling device of a wood board drilling machine. Background Art

[0002] When processing wooden boards, it is inevitable that holes need to be drilled on the side. At this time, a wooden board drilling machine is generally used. When the wooden board drilling machine is used, the wooden board needs to be fixed on the workbench, and the drilling device is arranged relative to the side of the workbench. The drilling device is fed to allow the drill to drill holes on the side of the wooden board.

[0003] In the prior art, in order to accurately control the drilling depth, it is necessary to calibrate the end of the drill bit after installing the drill bit and fixing the wooden board, and then set the feed stroke of the drilling device to control the drilling depth. In practice, it is found that when workers clamp and fix the wooden board, the position of the wooden board fluctuates greatly and it is difficult to maintain consistency. This results in inaccurate calibration position of the end of the drill bit and insufficient drilling depth each time a hole is drilled. Workers cannot calibrate before each drilling, which will reduce processing efficiency. Therefore, another structure that can control the drilling depth is needed. Utility Model Content

[0004] The main purpose of the utility model is to provide a drilling device for a wood board drilling machine, which is designed to control the drilling depth by extending and retracting a floating tube, and is convenient and quick.

[0005] According to a first aspect of the utility model, a drilling device for a wood board drilling machine is provided, comprising a first driving module and a base, wherein the base is connected to an output end of the first driving module, and the first driving module drives the base to move horizontally;

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements having the same or similar functions from beginning to end. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0023] The following disclosure provides many different embodiments or examples for implementing different solutions of the present invention.

[0024] Reference Figures 1 to 3 As shown, in one embodiment of the utility model, a drilling device of a wood board drilling machine includes a first driving module 1 and a base 2, the base 2 is connected to the output end of the first driving module 1, and the first driving module 1 drives the base 2 to move horizontally;

[0025] A vertical plate 3 is fixed on the base 2, and a second driving module 31 is installed on the vertical plate 3. A chuck 32 is provided at the output end of the second driving module 31, and a drill bit 33 is clamped in the chuck 32. The length direction of the drill bit 33 is parallel to the moving direction of the base 2.

[0026] Driven by the first driving module 1 , the drill bit 33 can move closer to or farther away from the wooden board, and the second driving module 31 drives the chuck 32 to rotate, thereby driving the drill bit 33 to rotate to perform drilling operations.

[0027] A sleeve 4 is provided on the vertical plate 3, in which a spring 41 is provided, and a floating tube 5 is also provided. The floating tube 5 is inserted in the sleeve 4 and cooperates with the spring 41 so that the floating tube 5 can elastically expand and contract along the moving direction of the base 2;

[0028] The floating tube 5 is provided with a detection strip 6 and also includes a sensor 7 for detecting the detection strip 6. The distance between the end of the floating tube 5 away from the casing 4 and the vertical plate 3 is a first distance, and the distance between the end of the drill bit 33 and the vertical plate 3 is a second distance.

[0029] When the floating tube 5 is in the extended state, the first spacing is the same as the second spacing, and the end of the floating tube 5 away from the casing 4 is flush with the end of the drill bit 33, and the sensor 7 is located between the detection strip 6 and the vertical plate 3, and the spacing between the detection strip 6 and the sensor 7 is the drilling depth;

[0030] When the drill bit 33 is drilling, the drilling depth of the drill bit 33 is the same as the retracted length of the floating tube 5. When the floating tube 5 is retracted until the detection strip 6 cooperates with the sensor 7, the retracted length of the floating tube 5 is the drilling depth, which means that the drilling depth of the drill bit 33 has reached the expected depth. After reaching the preset drilling depth, the first drive module 1 can be controlled to stop in time. Through this structure, the drilling depth can be accurately controlled even if the wooden board is replaced multiple times.

[0031] In this embodiment, the sensor 7 may be a photoelectric sensor or a limit switch.

[0032] In this embodiment, an open ring portion 61 is provided on the detection strip 6, and the open ring portion 61 is clamped on the floating tube 5, so that the position of the detection strip 6 on the floating tube 5 can be adjusted; when the floating tube 5 is in an extended state, the position of the detection strip 6 can be adjusted, thereby changing the distance between the detection strip 6 and the sensor 7, so that the drilling depth can be adjusted;

[0033] The open ring portion 61 includes two arc-shaped bars, one end of which is connected together through the detection bar 6, and a gap is left at the other end of the two arc-shaped bars. The two arc-shaped bars are connected by bolts, thereby narrowing or widening the gap, allowing the two arc-shaped bars to clamp or loosen the floating tube 5.

[0034] In this embodiment, a through slot 42 extending along the telescopic direction of the floating tube 5 is provided on the sleeve 4, and a limiting column 51 is provided on the outer peripheral wall of the end of the floating tube 5 away from the wooden board. The limiting column 51 is slidably matched with the through slot 42. The limiting column 51 can prevent the floating tube 5 from being separated from the sleeve 4, while the through slot 42 allows the limiting column 51 to move to avoid interference between the limiting column 51 and the sleeve 4.

[0035] Specifically, the limiting column 51 can be a screw, the screw is threadedly connected to the floating tube, and the screw head can be hidden in the through groove 42.

[0036] In this embodiment, the casing 4 is detachably connected to the vertical plate 3 so that the position of the casing 4 can be adjusted along the telescopic direction of the floating tube 5; after replacing the drill bit 33 of different lengths, the position of the floating tube 5 can be adjusted by adjusting the position of the casing 4, thereby ensuring that the end of the floating tube 5 away from the casing 4 can be flush with the end of the drill bit 33.

[0037] In this embodiment, the floating tube 5 and the drill bit 33 are at the same height, ensuring that the floating tube 5 and the drill bit 33 contact the wooden board at the same height, and the adjustment is more intuitive.

[0038] In this embodiment, the first driving module 1 is a linear module, and the second driving module 31 is a motor.

[0039] Although the embodiments of the present invention have been shown and described, those skilled in the art will appreciate that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the claims and their equivalents.
