[0003] The problem with existing technology is that in the use of existing wood processing drilling machines, drilling operations usually need to be completed through dual drive coordination. One drive source drives the drill bit to rotate to achieve the cutting action, while the other drive source controls the drill bit to press down to adjust the drilling depth, or the depth is controlled by manual pressing. However, the dual drive design has significant drawbacks. The simultaneous operation of the two drive sources increases power consumption and causes unnecessary energy waste. Manual pressing is not only time-consuming and laborious, but also makes it difficult to accurately control the drilling depth, which can easily affect the processing accuracy. Utility Model Content

This solves the problem that in the use of existing wood processing drilling machines, drilling operations usually require the cooperation of two drives: one drive source drives the drill bit to rotate to achieve the cutting action, and the other drive source controls the downward pressure of the drill bit to adjust the drilling depth, or the depth is controlled by manual pressure. However, the dual-drive design has significant drawbacks. The simultaneous operation of two drive sources increases power consumption, causing unnecessary energy waste, while manual pressure operation is not only time-consuming and laborious, but also makes it difficult to accurately control the drilling depth, which can easily affect the processing accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drilling machine for wood processing, comprising a processing table, wherein a drilling mechanism is provided on the top of the processing table.

[0018] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0021] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0022] Example 1 Reference Figure 1-5 This is the first embodiment of the present invention, which provides a drilling machine for wood processing, including a processing table 1, and a drilling mechanism 2 provided on the top of the processing table 1. The drilling mechanism 2 includes a vertical plate 21 and a support plate 22. The bottom of the vertical plate 21 is fixedly connected to the processing table 1, and the top of the vertical plate 21 is fixedly connected to the support plate 22. A lifting assembly 23 is provided on the rear side of the upright plate 21, a drilling assembly 24 for use with the lifting assembly 23 is provided on the front side of the bottom of the support plate 22, and a linkage assembly 25 for use with the drilling assembly 24 is provided on the front side of the top of the support plate 22.

[0023] Specifically, by setting the lifting component 23, the downward pressure depth of the drilling component 24 can be precisely controlled, ensuring the consistency of the wood drilling depth, avoiding errors from manual operation, and improving processing accuracy. By setting the drilling component 24, the wood can be drilled, making it easier for operators to process the wood. By setting up the linkage component 25, the function of simultaneously controlling the lifting and rotation of the drill bit 242 with a single drive source is realized, eliminating the need for two drive sources and reducing energy consumption.

[0024] Furthermore, the lifting component 23 provides lifting power to the drilling component 24, causing the drilling component 24 to move closer to or away from the wood. The linkage component 25 transmits the power of the lifting component 23 to the drilling component 24, enabling the drilling component 24 to rotate while lifting, thus completing the wood drilling operation.

[0025] Example 2 In the second embodiment of this utility model, the lifting assembly 23 includes a servo motor 231, a screw 232, and a first sprocket 233. The front side of the servo motor 231 is fixedly connected to the upright plate 21. The bottom of the screw 232 is fixedly connected to the output end of the servo motor 231. The top of the screw 232 passes through the support plate 22 and extends to the outside of the support plate 22, where it is fixedly connected to the first sprocket 233. A lifting plate 234 is sleeved on the surface of the screw 232 and is threadedly connected to the lifting plate 234.

[0026] A rectangular through hole 3 is provided on the rear side of the upright plate 21. A sliding post 4 is provided on the inner side of the rectangular through hole 3. The top and bottom of the sliding post 4 are fixedly connected to the inner wall of the rectangular through hole 3. The lifting plate 234 has its front end passing through the rectangular through hole 3 and extending to the outside of the rectangular through hole 3. The middle part of the lifting plate 234 is sleeved on the surface of the sliding column 4 and is slidably connected to the sliding column 4 through a linear bearing.

[0027] Specifically, by setting up a servo motor 231 and a screw 232, the servo motor 231 provides stable power, and the screw 232 is connected to the lifting plate 234 by a thread, so that the lifting plate 234 can be lifted and lowered precisely. By setting up a first sprocket 233 and a lifting plate 234, the first sprocket 233 can transmit power to the linkage component 25, while the lifting plate 234 can drive the drilling component 24 to move up and down. By setting a rectangular through hole 3 and a sliding column 4, the sliding column 4 and the linear bearing restrict the rotational freedom of the lifting plate 234, ensuring smooth lifting action without deviation.

[0028] Furthermore, after the servo motor 231 starts, its output drives the screw 232 to rotate. Since the lifting plate 234 is threadedly connected to the screw 232, and the lifting plate 234 is sleeved on the sliding column 4 through a linear bearing and cannot rotate with the screw 232, the rotational motion of the screw 232 is converted into the linear lifting motion of the lifting plate 234 along the sliding column 4. At the same time, the first sprocket 233 at the top of the screw 232 rotates synchronously with the screw 232, providing power to the linkage component 25.

[0029] Example 3 In the second embodiment of this utility model, the drilling assembly 24 includes a mounting block 241 and a drill bit 242. The top of the drill bit 242 is fixedly connected to the mounting block 241. The top of the mounting block 241 passes through the lifting plate 234 and extends to the outside of the lifting plate 234. It is rotatably connected to the through-hole of the lifting plate 234 through a bearing. A linkage column 243 is fixedly connected to the top of the mounting block 241.

[0030] Specifically, by setting up mounting block 241 and drill bit 242, and by connecting mounting block 241 to the bearing of lifting plate 234, the drilling assembly 24 can rotate independently while rising and falling with the lifting plate 234, ensuring that the drill bit 242 can complete the cutting action by rotating when it comes into contact with the wood. By setting the linkage column 243, the linkage column 243 is configured to receive the rotational power of the linkage component 25 and drive the mounting block 241 to rotate.

[0031] Furthermore, when the lifting plate 234 is raised and lowered, the mounting block 241 and the drill bit 242 are raised and lowered synchronously through the bearing, so that the drill bit 242 moves closer to or further away from the wood. When the linkage column 243 is subjected to rotational power, it drives the mounting block 241 and the drill bit 242 to rotate around the bearing connection between the mounting block 241 and the lifting plate 234, so that the drill bit 242 produces a cutting action when it contacts the wood, thus completing the drilling.

[0032] Example 4 In the second embodiment of this utility model, the linkage component 25 includes a second sprocket 251, a chain 252 and a hollow tube 253. The second sprocket 251 is sleeved on the outer surface of the top of the hollow tube 253 and is fixedly connected to the hollow tube 253. The two ends of the chain 252 are respectively fitted onto the surfaces of the first sprocket 233 and the second sprocket 251, and respectively mesh with the first sprocket 233 and the second sprocket 251; The bottom of the hollow tube 253 passes through the support plate 22 and extends to the outside of the support plate 22, and is rotatably connected to the support plate 22 through the through-hole of the support plate 22 via a bearing. The top of the linkage column 243 passes through the hollow tube 253 and extends to the outside of the hollow tube 253. Limiting columns 5 are provided on both the front and rear sides of the chain 252.

[0033] Both sides of the inner wall of the hollow tube 253 are provided with linkage grooves 6, and both sides of the surface of the linkage column 243 are fixedly connected with linkage blocks 7. There are multiple limiting columns 5, which are evenly distributed in a linear array and are fixedly connected to the bottom of the support plate 22. Among them, the side of the linkage block 7 away from the linkage column 243 passes through the linkage groove 6 and extends into the inner cavity of the linkage groove 6 to contact the inner wall of the linkage groove 6.

[0034] The surface of the limiting post 5 is fitted with a limiting bearing 8 and is fixedly connected to the inner ring of the limiting bearing 8. The outer ring of the limiting bearing 8 is in contact with the surface of the chain 252.

[0035] Specifically, by setting a second sprocket 251 and a chain 252, the rotational power of the first sprocket 233 is transmitted to the second sprocket 251 through the chain 252, thus realizing the power transmission of a single drive source; By setting up hollow tube 253, linkage groove 6 and linkage block 7, the hollow tube 253 and linkage column 243 can transmit rotational power through the cooperation of linkage groove 6 and linkage block 7, without affecting the lifting and lowering of linkage column 243 with lifting plate 234. By setting the limit post 5 and the limit bearing 8, the limit post 5 and the limit bearing 8 play a supporting and guiding role for the chain 252, preventing the chain 252 from loosening or deviating, and ensuring the stability of power transmission.

[0036] Furthermore, when the first sprocket 233 rotates with the screw 232, it drives the second sprocket 251 to rotate via the chain 252. The second sprocket 251 drives the hollow tube 253 to rotate around the bearing connection between it and the support plate 22. When the hollow tube 253 rotates, the linkage groove 6 on the inner wall contacts the linkage block 7 on the linkage column 243, causing the linkage column 243 to rotate synchronously, thereby causing the mounting block 241 and the drill bit 242 to rotate. At the same time, since the linkage block 7 can slide axially in the linkage groove 6, the linkage column 243 will not be obstructed by the hollow tube 253 when it rises and falls with the lifting plate 234, thus realizing the synchronous operation of rotation and lifting.

[0037] Working principle: When drilling is required in the wood, the servo motor 231 is started. The output end of the servo motor 231 drives the screw 232 to rotate. On the one hand, the screw 232 is connected to the lifting plate 234 by a thread. Under the limiting action of the sliding column 4, the rotational motion is converted into the linear downward motion of the lifting plate 234. The lifting plate 234 drives the drilling assembly 24 mounting block 241, the drill bit 242 and the linkage column 243 to move down as a whole, so that the drill bit 242 gradually approaches the wood. On the other hand, the first sprocket 233 at the top of the screw 232 rotates synchronously with the screw 232, and drives the second sprocket 251 to rotate through the chain 252. The second sprocket 251 drives the hollow tube 253 to rotate. The hollow tube 253 cooperates with the linkage block 7 on the linkage column 243 through the linkage groove 6 on the inner wall, and transmits the rotational power to the linkage column 243, thereby driving the mounting block 241 and the drill bit 242 to rotate. During the drilling process, the drill bit 242 rotates while continuously moving downward with the lifting plate 234 to complete the cutting and drilling action on the wood. After the drilling is completed, the servo motor 231 reverses, the screw 232 drives the lifting plate 234 to rise, the drill bit 242 rotates in the opposite direction, disengages from the wood and resets, and at the same time the first sprocket 233 drives the relevant components to reverse through the chain 252. Then the servo motor 231 stops, the drill bit 242 stops rotating, and the processing is completed.

[0038] In summary, by setting up drilling mechanism 2, the drill bit rotation and downward pressing actions can be realized simultaneously through a single drive source, which effectively reduces the energy consumption of drive components while ensuring precise control of drilling depth.
