Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.
[0025] according to Figure 1 、 2 As shown in FIG. 3 , a wood punching machine is proposed in this embodiment, including a connecting column 3, a handle 1 is provided at the upper end of the connecting column 3, a drill bit 14 is provided at the lower end of the connecting column 3, and further comprising:
[0026] The dust cover 6 surrounds the drill bit 14 to prevent debris from splashing. When the drill bit 14 is drilling, the generated debris will be blocked by the dust cover 6 to protect the operator.
[0027] A second sliding sleeve 5 is sleeved on the outside of the connecting column 3. The second sliding sleeve 5 is fixedly connected to the upper end of the dust cover 6. The second sliding sleeve 5 is slidably connected to the connecting column 3.
[0028] The first sliding sleeve 4 is sleeved on the outside of the connecting column 3, and the first sliding sleeve 4 is slidingly connected to the connecting column 3. A spring support structure is provided between the first sliding sleeve 4 and the second sliding sleeve 5, and the second sliding sleeve 5 is floatingly connected to the first sliding sleeve 4 through the spring support structure; the advantage of this design is that the dust cover 6 will remain in close contact with the wooden board under the push of the spring support structure, and when the drill bit 14 falls quickly, no high-intensity collision will occur between the dust cover 6 and the wooden board, thereby improving the safety of the punching machine when in use.
[0029] The adjusting device is placed between the handle 1 and the first sliding sleeve 4 and is used to adjust the height of the first sliding sleeve 4. The height of the first sliding sleeve 4 and the pushing force of the spring support structure on the second sliding sleeve 5 are adjustable, which is highly flexible.
[0030] For the specific structure of the spring support structure, please refer to the following description.
[0031] The spring support structure includes a first fixed seat 7, a fourth sliding sleeve 8, a limiting rod 9 and a spring 10. The first fixed seat 7 is fixedly connected to the outside of the second sliding sleeve 5, the fourth sliding sleeve 8 is fixedly connected to the outside of the first sliding sleeve 4, the fourth sliding sleeve 8 is placed above the first fixed seat 7, the limiting rod 9 is fixedly connected to the upper end of the first fixed seat 7, the limiting rod 9 passes through the fourth sliding sleeve 8 at one end away from the first fixed seat 7, the limiting rod 9 is slidably connected to the fourth sliding sleeve 8, the spring 10 is sleeved on the outside of the limiting rod 9, and the two ends of the spring 10 are fixedly connected to the fourth sliding sleeve 8 and the first fixed seat 7 respectively.
[0032] The spring support structure works as follows: multiple first fixing seats 7 are located outside the second sleeve 5, and multiple fourth sleeves 8 are located outside the first sleeve 4. Each fourth sleeve 8 is positioned above a respective first fixing seat 7. The fourth sleeves 8 and first fixing seats 7 are connected by springs 10. When the dust cover 6 contacts the board surface, the force applied to the dust cover 6 pushes the second sleeve 5 toward the first sleeve 4. The springs 10 between the first fixing seats 7 and the fourth sleeves 8 contract, pushing the dust cover 6 to maintain a close contact with the table surface. A limit rod 9 guides and limits the second sleeve 5.
[0033] About the adjustment device:
[0034] The adjusting device includes a second fixing seat 11, a third fixing seat 12 and an adjusting bolt 13. The third fixing seat 12 is fixedly connected to the outside of the handle 1, the second fixing seat 11 is fixedly connected to the outside of the first sliding sleeve 4, the adjusting bolt 13 passes through the third fixing seat 12, the adjusting bolt 13 is threadedly connected to the third fixing seat 12, and the lower end of the adjusting bolt 13 is rotatably connected to the upper end of the second fixing seat 11.
[0035] The working principle of the adjustment device is: rotate the adjusting bolt 13, and the adjusting bolt 13 is screwed downward along the third fixed seat 12. Under the push of the adjusting bolt 13, the second fixed seat 11 will also fall down. Since the second fixed seat 11 is fixed to the first sliding sleeve 4, when the handle 1 falls, the first sliding sleeve 4 pushes the second sliding sleeve 5 and the dust cover 6 to fall together through the spring support structure. When the dust cover 6 contacts the board surface, the elastic support strength of the spring support structure will also be strengthened to ensure that the dust cover 6 is in close contact with the board surface.
[0036] Specifically, the handle 1 has a plurality of bolt holes 2 at its upper end, and fixing bolts are installed in the bolt holes 2. The handle 1 is fixed to an external frame or an adjustable arm by bolt connection, and the handle 1 is raised and lowered by mechanical equipment to complete drilling, thereby improving work efficiency.
[0037] More specifically, the dust cover 6 is a conical cover, and the length and width of the upper end of the dust cover 6 are smaller than the length and width of the lower end of the dust cover 6. The conical structure of the dust cover 6 has better dustproof effect and stability, especially in terms of dustproof effect and stability at the bottom.
[0038] In order to increase the stability of the first sliding sleeve 4 when sliding up and down, a better implementation method is that a third sliding sleeve 17 is provided on the outside of the first sliding sleeve 4, and a fourth fixing seat 16 is provided on the outside of the handle 1. The fourth fixing seat 16 is placed above the third sliding sleeve 17, and a guide rod 18 is provided at the lower end of the fourth fixing seat 16. The guide rod 18 is fixedly connected to the fourth fixing seat 16, and the lower end of the guide rod 18 passes through the third sliding sleeve 17 and is slidably connected to the third sliding sleeve 17.
[0039] When the first sliding sleeve 4 is pushed down by the adjusting device, the third sliding sleeve 17 fixed to the first sliding sleeve 4 will also fall down together. The first sliding sleeve 4 is sleeved on the outside of the guide rod 18. The guide rod 18 will guide the third sliding sleeve 17 and the first sliding sleeve 4 by cooperating with the third sliding sleeve 17, thereby improving the stability of the first sliding sleeve 4 when sliding along the outer wall of the connecting column 3.
[0040] Another better embodiment is that at least two laser emitters 15 are provided at the lower end of the connecting column 3, and each of the laser emitters 15 is respectively surrounded by the fourth fixing seat 16. When drilling, the laser emitter 15 can mark the landing point of the drill bit 14 in advance to assist the staff in drilling.
[0041] To prevent the dust cover 6 from being continuously pulled, causing the limiting rod 9 fixed to the first fixing seat 7 to be pulled out of the fourth sliding sleeve 8, in a preferred embodiment, a cylindrical stopper is provided at the end of the limiting rod 9 away from the first fixing seat 7. The cylindrical stopper is positioned above the fourth sliding sleeve 8 and has a diameter larger than that of the fourth sliding sleeve 8. When the limiting rod 9 is continuously pulled, the cylindrical stopper fixed to the upper end of the limiting rod 9 will get stuck on the upper end of the fourth sliding sleeve 8, preventing the limiting rod 9 from sliding further downward.
[0042] How this application works:
[0043] When the drill bit 14 drills a hole, the generated debris will be blocked by the dust cover 6 to protect the operator.
[0044] After receiving the force, the dust cover 6 will push the second sliding sleeve 5 to slide toward the first sliding sleeve 4, and the spring 10 between the first fixing seat 7 and the first sliding sleeve 8 will shrink. Under the push of the spring 10, the dust cover 6 will remain in close contact with the desktop.
[0045] Turn the adjusting bolt 13, and the adjusting bolt 13 will be screwed downward along the third fixing seat 12. Under the push of the adjusting bolt 13, the second fixing seat 11 will also fall down. Since the second fixing seat 11 is fixed to the first sliding sleeve 4, when the handle 1 falls, the first sliding sleeve 4 pushes the second sliding sleeve 5 and the dust cover 6 to fall together through the spring support structure. When the dust cover 6 contacts the board surface, the elastic support strength of the spring support structure will also be strengthened to ensure that the dust cover 6 is always in close contact with the board surface.
