[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] This utility model provides, for example Figure 1-4The illustrated wood drilling auxiliary positioning device includes a fixed base plate 1 and a drilling mechanism 5. Two linear guide rails 1-2 are respectively installed on the top outer wall of the fixed base plate 1. Each linear guide rail 1-2 is connected to a supporting base plate 3 via a slider. A processing base plate 15 is installed on the top outer wall of the supporting base plate 3. Two linear guide rails 2-4 are respectively installed on the top outer wall of the supporting base plate 3. Each linear guide rail 2-4 is connected to a supporting base 6 via a slider. The number of linear guide rails 2-4 is also two. All rails 2 and 4 are standard parts. A clamping assembly 7 for fixing the plate is installed on the top outer wall of the support base 6. A drive motor 9 is installed on the bottom outer wall of the support base plate 3. A drive gear 10 is connected to the output end of the drive motor 9. A short rack 11 is installed on the bottom outer wall of the support base 6. The two short racks 11 at the bottom of the two support bases 6 are located on opposite sides of the drive gear 10, so that when the drive gear 10 rotates, the two short racks 11 move in opposite directions, and the drive gear 10 meshes with the short racks 11. A support frame 12 is installed on the top outer wall of the fixed base plate 1. A translation mechanism 8 for moving the drilling mechanism 5 is installed on the support frame 12. The clamping assembly 7 includes a push rod base plate 701, which is located on the top outer wall of the support base 6. An electric push rod 702 is installed on the top outer wall of the push rod base plate 701. A clamping plate 703 is connected to the output end of the electric push rod 702. When using this device, the wood is first placed above the processing base plate 15, and then the drive motor 9 drives the drive gear 1. The rotation of the 0-axis causes the two short racks 11 to move their respective support bases 6, thereby limiting the sides of the wood. Then, the electric push rod 702 drives the pressing plate 703 to descend and press the wood. This device can limit and fix wood of different sizes by adjusting the position of the support bases 6. After fixing the wood, the support base plate 3 is moved longitudinally, and then the drilling mechanism 5 is moved laterally by the translation mechanism 8, thereby adjusting the drilling position of the drilling mechanism 5.

[0024] In this embodiment, as Figure 1 As shown, guide posts 704 are installed on the top outer wall of the clamping plate 703. The guide posts 704 are slidably engaged with the push rod base plate 701. The guide posts 704 can guide the clamping plate 703, which helps to improve the stability of the clamping plate 703 when it moves up and down.

[0025] In this embodiment, as Figure 2 As shown, a reversible motor 13 is installed on the bottom outer wall of the support base plate 3. A drive gear 14 is connected to the output end of the reversible motor 13. A long rack 16 is installed on the bottom outer wall of the fixed base plate 1. The drive gear 14 meshes with the long rack 16. The reversible motor 13 drives the drive gear 14 at its output end to rotate, thereby driving the support base plate 3 to rotate.

[0026] In this embodiment, as Figure 4 As shown, the translation mechanism 8 includes a ball screw 801, which is rotatably connected to the support frame 12. The ball screw 801 is connected to a support block 802 via a ball nut. The support block 802 is connected to the drilling mechanism 5. A guide rod 803 is slidably engaged on the support block 802 and is connected to the support frame 12. The guide rod 803 guides the support block 802. A servo motor is mounted on the support frame 12. The output end of the servo motor is connected to one end of the ball screw 801. The servo motor drives the ball screw 801 to rotate, which enables the ball screw 801 to move the support block 802 laterally, thereby moving the drilling mechanism 5.

[0027] Working principle of this utility model: This utility model is a wood drilling auxiliary positioning device. By placing the wood on the processing base plate 15, the drive motor 9 drives the drive gear 10 to rotate, so that the two short racks 11 can drive the corresponding support bases 6 to move respectively, so that the two support bases 6 can limit the side of the wood.

[0028] Next, the electric push rod 702 drives the pressure plate 703 to descend, so that the pressure plate 703 can press the wood, thereby stably fixing the wood. Therefore, by adjusting the position of the support base 6, the device can stably limit and fix wood of different sizes, which is beneficial for subsequent drilling of holes in the wood.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
