[0004] Existing side-hole drilling technology has a complex process flow, low precision, large deviation between the preset hole position and the actual hole position on the plate, complex mechanical structure, and high maintenance cost. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: In view of the shortcomings of the prior art, the purpose of this utility model is to provide a direct drive synchronous side hole machine. By adding the direct drive synchronous side hole machine to the rear section of the fully automatic edge banding machine, the side hole is made synchronously with the edge banding machine, forming a fully automatic integrated machine for edge banding and side hole making. This reduces the process of transporting the edge banded material to the side hole equipment, greatly saves manpower, and reduces the process defect rate of the board material. It also solves the problems of excessive manual input and slow processing efficiency in the prior art.

[0006] This utility model is achieved through the following technical solution: a direct-drive synchronous side-drilling machine, used in an edge banding machine to drill holes on the side of a sheet or profile, comprising: an X-axis direct-drive motor module with the same speed as the displacement mechanism of the edge banding machine; a drilling body moving mechanism that drives the drilling mechanism to move along a first direction to move the drilling mechanism to a set drilling position on the sheet or profile; a drilling height displacement mechanism that drives the drilling mechanism to move along a second direction to move the drilling mechanism to a set drilling depth; and an electrical control part that controls the X-axis direct-drive motor module, the drilling body moving mechanism, and the drilling height displacement mechanism to cooperate with the edge banding machine in drilling. The drilling height displacement mechanism includes a first connecting plate connected to the X-axis direct drive motor module and extending along a first direction, and a second connecting plate connected to the first connecting plate and extending along a second direction. The second connecting plate has a first groove and a second groove on both sides along the second direction, and a first I-shaped slide rail is fixedly installed in each of the first and second grooves. A first connecting fixing body is provided on the top of the second connecting plate, and a first servo motor is provided on the first connecting fixing body. The output shaft of the first servo motor is connected via a coupling to a first transmission screw connected to the drilling body moving mechanism, and the first transmission screw extends along the second direction. An elastic body is provided on the end face of the first connecting plate that can contact the drilling body moving mechanism. The drilling body moving mechanism includes a third connecting plate extending along a first direction, slidably connected to a first I-shaped slide rail, and driven by a first transmission screw. The third connecting plate has a third groove and a fourth groove extending along the first direction on its upper and lower sides, and a second I-shaped slide rail is fixed in each of the third groove and the fourth groove. A second connecting fixing body is provided at one end of the third connecting plate, and a second servo motor is provided on the second connecting fixing body. The output shaft of the second servo motor is connected to a second transmission screw connected to the drilling mechanism through a coupling. The second transmission screw extends along the first direction. The drilling mechanism is slidably mounted on the second I-shaped slide rail.

[0007] Furthermore, the X-axis direct drive motor module is aligned with the third-party direction.

[0008] Furthermore, the first direction and the second direction are perpendicular to each other.

[0009] Furthermore, the electrical control section includes a chassis, which houses electrical control components.

[0010] Furthermore, the drilling mechanism employs a drilling machine.

[0011] Furthermore, the connecting ends of the first connecting plate and the second connecting plate are provided with reinforcing plates that are fixedly connected to the first connecting plate and the second connecting plate respectively. There are two reinforcing plates, and the end connected to the first connecting plate is embedded in the first connecting plate.

The transmission connecting block is located on one side of the motor mounting plate and is provided with a guide transmission component, which is provided with a threaded hole.

[0013] The beneficial effects of this utility model are as follows: By using a direct drive motor module as the power response output in the X-axis direction, and utilizing the high speed, high acceleration, and high precision characteristics of the linear motor, the moving speed of the X-axis direct drive motor module is controlled to be synchronized with the speed of the plate being moved by the displacement mechanism. This ensures accurate synchronization of the plate's movement at low, medium, and high speeds, as well as high-speed response and synchronous following, ensuring that the drilling speed matches the plate's movement speed, thereby improving drilling efficiency. Furthermore, the servo motor on the drilling height displacement mechanism can automatically adjust the height according to different plate thicknesses. In conjunction with the servo motor's transmission to the lead screw, it provides convenient control, precise displacement, and stable locking of the drill bit in the drilling mechanism. The drilling body moving mechanism, acting as the first direction, provides thrust to the drilling motor to achieve drilling depth. In conjunction with the servo motor's transmission to the lead screw, it provides continuous and stable drilling feed and return-to-origin actions for the drill bit in the drilling mechanism.

Detailed Implementation

[0015] To make the above-mentioned objects, 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. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0016] like Figure 1 , Figure 2 and Figure 6As shown, the direct-drive synchronous side-drilling machine of this utility model mainly includes an X-axis direct-drive motor module 1, a drilling height displacement mechanism 2, a drilling body moving mechanism 3, a drilling mechanism 4, and an electrical control unit 5. The X-axis direct-drive motor module 1 serves as the basic moving platform of the entire machine, and its direction of movement is defined as the third direction. This X-axis direct-drive motor module 1 uses a high-response-speed direct-drive motor to ensure that its moving speed is synchronized with the displacement mechanism inside the edge banding machine. The electrical control unit 5 receives the operating signal from the edge banding machine and controls the X-axis direct-drive motor module 1, the drilling height displacement mechanism 2, the drilling body moving mechanism 3, and the drilling mechanism 4 to achieve real-time matching with the moving speed of the board material, thereby achieving synchronous following drilling.

[0017] like Figure 3 As shown, the drilling height displacement mechanism 2 is responsible for driving the drilling mechanism 4 along a second direction, which is perpendicular to the side of the plate. That is, it adjusts the drilling position of the drilling mechanism 4 according to the thickness of the plate to achieve the height positioning of the drilling mechanism 4. The drilling height displacement mechanism 2 mainly includes a first connecting plate 21, a second connecting plate 22, a first servo motor 23, and a first transmission screw 24.

[0018] The first connecting plate 21 is fixedly connected to the X-axis direct drive motor module 1 and extends along the first direction. The second connecting plate 22 is fixedly connected to the first connecting plate 21 and extends along the second direction. To improve the connection strength, two reinforcing plates 25 are provided at the connection between the first connecting plate 21 and the second connecting plate 22. One end of the reinforcing plate 25 is embedded in the first connecting plate 21 and fastened to both with bolts. The second connecting plate 22 has a first groove and a second groove respectively opened on both sides along the second direction, and a first I-shaped slide rail 26 is fixedly installed in each groove.

[0019] A first connecting fixing body 27 is provided on the top of the second connecting plate 22. The first connecting fixing body 27 consists of a motor mounting plate and a transmission connecting block, with the motor mounting plate extending along a third direction. A first servo motor 23 is fixedly mounted on the motor mounting plate, and its output shaft is connected to a first transmission lead screw 24 via a coupling. The first transmission lead screw 24 extends along a second direction and passes through a guide transmission component on the transmission connecting block. A guide transmission component with a threaded hole is provided on the transmission connecting block, forming a helical transmission pair with the first transmission lead screw 24. An elastic body 28 is also provided on the end face of the first connecting plate 21; when the drilling body moving mechanism 3 moves downward, it can contact the elastic body 28, which plays a role in buffering and limiting.

[0020] like Figure 4 As shown, the drilling body moving mechanism 3 is mounted on the drilling height displacement mechanism 2, and is responsible for driving the drilling mechanism 4 to move along the first direction (drilling depth), so that the drilling mechanism 4 drills holes in the plate. The drilling body moving mechanism 3 mainly includes a third connecting plate 31, a second servo motor 32, and a second transmission screw 33.

[0021] The third connecting plate 31 extends along the first direction, and its side opposite to the second connecting plate 22 is slidably connected to the first I-shaped slide rail 26 via a slider. The third connecting plate 31 is provided with a connecting block that cooperates with the first transmission screw 24. By driving the first transmission screw 24 to rotate through the first servo motor 23, the entire third connecting plate 31 can be moved along the second direction (the thickness direction of the plate).

[0022] The third connecting plate 31 has a third groove and a fourth groove extending along the first direction on its upper and lower sides, respectively, and a second I-shaped slide rail 34 is fixedly installed in each groove. A second connecting fixing body 35 is provided at one end of the third connecting plate 31. The second connecting fixing body 35 is also composed of a motor mounting plate and a transmission connecting block, extending along the third direction of the motor mounting plate. The second servo motor 32 is fixedly installed on the motor mounting plate, and its output shaft is connected to the second transmission lead screw 33 via a coupling. The second transmission lead screw 33 extends along the first direction and passes through the guide transmission component on the transmission connecting block. The guide transmission component with threaded holes on the transmission connecting block forms a helical transmission pair with the second transmission lead screw 33.

[0023] In this embodiment, the drilling mechanism 4 uses a standard drilling machine, such as a high-speed electric spindle. The drilling mechanism 4 is slidably mounted on the second I-shaped slide rail 34 via a slider, and its base is provided with a connecting block that cooperates with the second transmission lead screw 33. When the second servo motor 32 drives the second transmission lead screw 33 to rotate, it can drive the drilling mechanism 4 to move precisely along the first direction.

[0024] like Figure 5 As shown, the electrical control section 5 is the control center of the equipment, which includes a chassis 51. The chassis houses necessary electrical control components such as circuit breakers, contactors, and drivers. A PLC control device 52 and an emergency stop control button 53 are located on the top of the chassis 51. A perforated plate 54 is provided on the side wall of the chassis 51, and a cooling fan 55 is installed to ensure that the electrical control components operate at a suitable temperature. The PLC control device 52 is connected via communication lines to the X-axis direct drive motor module 1, the first servo motor 23, the second servo motor 32, and the control system of the edge banding machine, coordinating the sequence and speed synchronization of the actions of each part.

[0025] It should be noted that in this embodiment, the X-axis direct drive motor module is aligned with the third direction, and the first and second directions are perpendicular. Alternatively, the first direction can be taken as the Y-axis axis, the second direction as the Z-axis axis, and the third direction as the X-axis axis.

[0026] Work process: Synchronous Start: When the board material is edge-banded on the edge banding machine and continues to be conveyed, the edge banding machine sends a signal. The electrical control unit 5 starts the X-axis direct drive motor module 1, making it move synchronously at a speed exactly the same as the conveying speed of the edge banding machine.

[0027] Positioning: At the same time, according to the preset processing program, the first servo motor 23 starts and drives the drilling mechanism 4 to move along the second direction through the first transmission screw 24, accurately reaching the position where drilling is required on the side of the plate.

[0028] Drilling: Once the position and synchronization speed are ready, the second servo motor 32 starts, driving the entire drilling mechanism 4 to feed rapidly along the first direction via the second transmission screw 33. The drilling mechanism 4 then starts rotating on its own, completing the drilling to the set depth.

[0029] Retraction: After the drilling reaches the set depth, the second servo motor 32 reverses, driving the drilling mechanism 4 to exit the board and wait for drilling at the next position.

[0030] Cycle: The above process is carried out continuously during the sheet material conveying process until all side holes on a sheet material are processed. The X-axis direct drive motor module 1, drilling height displacement mechanism 2, and drilling body moving mechanism 3 then quickly return to the starting point to prepare for processing the next sheet material.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
