[0001] This utility model relates to the field of drilling technology, specifically to an automatic woodworking scale-adjusting drilling device. Background Technology

[0002] Woodworking drilling machines are core equipment in mechanical drilling operations, holding a crucial position and having extremely wide applications. In the important field of furniture manufacturing, they play an indispensable role, especially in the drilling processes of wardrobes, cabinets, and other furniture products, where they exert a vital influence, providing strong support for efficient and precise furniture production.

[0003] However, the single-row drilling machines commonly found on the market have certain limitations, as their drill bit positions are usually fixed. When the drill bit position needs to be adjusted, operators have to manually disassemble and then readjust and reinstall it, making the whole process quite cumbersome.

The dual-axis motor is fixedly mounted on the support, and the protective mounting shell is fixedly mounted on both sides of the dual-axis motor. A transmission rod is fixedly connected to each output end of the dual-axis motor. A driving bevel gear is fixedly mounted on one side of the transmission rod.

One side wall of the first threaded block is fixedly connected to one side wall of the mounting shell. Four sets of protective mounting shells are fixedly mounted on the two rectangular sides of the mounting shell.

[0009] Furthermore, the adjusting mechanism includes a first stepper motor and a mounting bracket. The mounting bracket is fixedly mounted on one side wall of the mounting housing, and the first stepper motor is fixedly mounted on the mounting bracket. A screw is rotatably mounted inside the mounting bracket. The output end of the first stepper motor passes through one side wall of the mounting bracket and is connected to the screw. A threaded sleeve is threadedly connected to the screw. A sliding mounting bracket is slidably mounted on the threaded sleeve. An electric push rod is fixedly mounted on the threaded sleeve. The telescopic end of the electric push rod is fixedly connected to the sliding mounting bracket. A second stepper motor is mounted on the sliding mounting bracket. The output end of the second stepper motor is provided with a plug-in sleeve. Multiple sets of plug-in threaded rods are rotatably mounted inside the mounting housing. The multiple sets of plug-in threaded rods are arranged in parallel. One end of each plug-in threaded rod passes through the side wall of the mounting housing. Second threaded blocks are threadedly connected to the multiple sets of plug-in threaded rods.

[0010] Furthermore, a drilling drive mechanism is fixedly connected to the bottom of the second threaded block. The protruding end of the threaded rod and the inner hole of the plug-in sleeve are both polygonal, and the size of the plug-in sleeve is adapted to the size of the threaded rod. The opening end of the plug-in sleeve is trumpet-shaped.

[0011] Furthermore, the drilling drive mechanism includes a drilling body, a sliding rod, a sliding bracket, a belt, a pulley, and a mounting slider.

[0014] 1. This utility model uses a second threaded block to drive the drilling drive mechanism to adjust the corresponding spacing, enabling the machine tool to quickly adapt to different drilling positions and hole spacing requirements. Unlike traditional methods, it eliminates the need for frequent disassembly and adjustment of the drill bit, reducing equipment failures caused by frequent drill bit disassembly and adjustment, lowering maintenance costs and downtime, thereby improving production efficiency. Furthermore, the synchronous adjustment of the electric push rod during the movement of the spacing adjustment mechanism prevents the belt from slipping due to insufficient tension caused by the movement of the drilling body, improving equipment stability. At the same time, the synchronous linkage between the drilling drive mechanism and the spacing adjustment mechanism reduces energy consumption and lowers production costs compared to traditional multi-power source drive methods.

[0024] As shown in Figures 1 to 4, an automatic woodworking scale-adjusting drilling device includes a fixed bracket 1 and a lifting mechanism 2. Specifically, as shown in Figure 2, the lifting mechanism 2 includes a dual-axis motor 201 and a protective mounting shell 207. The dual-axis motor 201 is fixedly mounted on the fixed bracket 1, and the protective mounting shell 207 is fixedly mounted on both sides of the dual-axis motor 201. A transmission rod 202 is fixedly connected to the output ends of both sides of the dual-axis motor 201. A drive bevel gear 204 is fixedly mounted on one side of each transmission rod 202. The protective mounting shell 207 is connected to the... A first threaded rod 203 is rotatably mounted longitudinally on the fixed bracket 1. A driven bevel gear 205 is fixedly mounted on one end of the first threaded rod 203. The driven bevel gear 205 meshes with the driving bevel gear 204. A first threaded block 206 is threadedly connected to the first threaded rod 203. One side wall of the first threaded block 206 is fixedly connected to one side wall of the mounting shell 5. Four sets of protective mounting shells 207 are fixedly mounted on both sides of the mounting shell 5 in a rectangular configuration. The protective mounting shells 207 are slidably mounted with the sliding grooves in the fixed bracket 1.

[0025] More specifically, after the preparation work is completed, when the dual-axis motor 201 drives the transmission rod 202, the active bevel gear 204 rotates and drives the first threaded rod 203 to rotate through the meshing driven bevel gear 205, causing the first threaded block 206 to drive the mounting shell 5 to move down synchronously, so that the drilling drive mechanism 8 inside the mounting shell 5 can perform drilling operations on the plate on the operating table body 6, and the protective mounting shell 207 plays a protective role.

[0026] A mounting shell 5 is slidably disposed on the lifting mechanism 2. The lifting mechanism 2 is mounted on the fixed bracket 1. A drilling drive mechanism 8 for processing the sheet metal is disposed inside the mounting shell 5, as shown in Figures 3-4. Specifically, the drilling drive mechanism 8 includes a drill body 801, a slide rod 803, a sliding bracket 804, a belt 807, a pulley 809, and a mounting slider 8010. The mounting slider 8010 is slidably disposed with the mounting shell 5. The drill body 801 is fixedly disposed on one side of the mounting slider 8010. The slide rod 803 is fixedly installed on the two inner side walls inside the mounting shell 5. The sliding bracket 807... 4. The slide rod 803 is slidably arranged. An electric push rod 802 is fixedly installed on one side wall inside the mounting shell 5. The telescopic end of the electric push rod 802 is fixedly connected to one side wall of the sliding bracket 804. A drive motor 805 is fixedly installed on the other side wall of the sliding bracket 804. An auxiliary tensioning wheel 806 is provided on the mounting shell 5. An auxiliary wheel frame 808 is fixedly installed on one set of mounting sliders 8010. Both the drilling body 801 and the drive motor 805 are provided with pulleys 809. The pulleys 809 are connected to the auxiliary tensioning wheel 806 and the auxiliary wheel frame 808 through the belt 807.

[0027] More specifically, when drilling, the drive motor 805 drives the pulley 809 to rotate the auxiliary wheel frame 808 and the auxiliary tension wheel 806 connected by the belt 807. This causes the pulley 809 to rotate the drilling body 801 to perform the drilling operation on the plate. When the second threaded block 401 drives the drilling body 801 to adjust the spacing, when the outermost drilling body 801 retracts, the electric actuator 802 simultaneously drives the sliding bracket 804 and the drive motor 805 to retract, causing the pulley 809, the auxiliary tension wheel 806, and the belt 807 on the auxiliary wheel frame 808 to be tightened simultaneously. The height of the auxiliary tension wheel 806 is also adjusted. The drive motor 805 is positioned above its maximum limit and also serves as a guide. The tension of the belt 807 is increased through synchronous adjustment, preventing the belt 807 from slipping off due to insufficient tension caused by the movement of the drilling body 801. This improves the stability of the equipment. Compared with the traditional multi-power source drive method, the linkage drive reduces energy consumption and production costs. Furthermore, when the electric push rod 802 is at its maximum extension limit, the angle between the pulley 809 on the drive motor 805 and the belt 807 is not less than 120°. The sliding bracket 804 and the sliding rod 803 further improve the stability of the drive motor 805 during movement.

[0028] The drilling drive mechanism 8 is connected to a spacing adjustment mechanism 4 for adjusting the spacing dimension of the drilling drive mechanism 8, as shown in Figures 3-4. Specifically, the spacing adjustment mechanism 4 includes a first stepper motor 404 and a mounting bracket 403. The mounting bracket 403 is fixedly mounted on one side wall of the mounting housing 5. The first stepper motor 404 is fixedly mounted on the mounting bracket 403. A screw 406 is rotatably mounted inside the mounting bracket 403. The output end of the first stepper motor 404 passes through one side wall of the mounting bracket 403 and is connected to the screw 406. A threaded sleeve 405 is threadedly connected to the screw 406. A sliding mounting bracket 407 is slidably mounted on the threaded sleeve 405. An electric push rod 402 is fixedly mounted on the threaded sleeve 405. The telescopic end of the electric push rod 402 is fixedly connected to the sliding mounting bracket 407. A second stepper motor 4010 is mounted on the sliding mounting bracket 407. The output end of the second stepper motor 4010 is provided with a plug-in sleeve 409. Multiple sets of plug-in threaded rods 408 are rotatably mounted inside the mounting shell 5. The multiple sets of plug-in threaded rods 408 are arranged in parallel. One end of each plug-in threaded rod 408 penetrates the side wall of the mounting shell 5. A second threaded block 401 is threadedly connected to each of the multiple sets of plug-in threaded rods 408.

[0029] More specifically, when the spacing of the drilling drive mechanism 8 needs to be adjusted, the PLC controller 3 sends an electrical signal to drive the first stepper motor 404 to rotate the screw 406, causing the threaded sleeve block 405 to move. When it moves to the corresponding threaded rod 408 that needs adjustment, the electric push rod 402 pushes the sliding mounting bracket 407 to slide along the threaded sleeve block 405. The second stepper motor 4010 and the insertion sleeve 409 on the second stepper motor 4010 are inserted into the extended end of the threaded rod 408. At this time, the second stepper motor 4010 drives the threaded rod 408 to rotate, causing the second threaded block 401 on the threaded rod 408 to move and adjust the drilling drive mechanism 8. This reduces manual operation by the operator, reduces labor intensity, and reduces equipment failures caused by frequent disassembly and adjustment of the drill bit, reducing maintenance costs and downtime. At the same time, independent adjustment can better meet the drilling accuracy and quality requirements.

[0030] An operating platform body 6 for placing plates is provided below the mounting shell 5, and a PLC controller 3 is provided on one side wall of the lifting mechanism 2.

[0031] As shown in Figures 3-4, a drilling drive mechanism 8 is fixedly connected to the bottom of the second threaded block 401. The protruding end of the insertion threaded rod 408 and the inner hole of the insertion sleeve 409 are both polygonal, and the size of the insertion sleeve 409 is adapted to the size of the insertion threaded rod 408. The opening end of the insertion sleeve 409 is flared. Specifically, the flared opening of the insertion sleeve 409 facilitates the insertion of the insertion sleeve 409 onto the insertion threaded rod 408, improving the accuracy of insertion.

[0032] As shown in Figure 4, an auxiliary pressing block 7 is provided at the bottom of the mounting slider 8010. The length of the auxiliary pressing block 7 is longer than the length of the drill bit of the drilling body 801. The bottom of the auxiliary pressing block 7 is made of rubber material to increase friction. Specifically, when the lifting mechanism 2 drives the drilling drive mechanism 8 to descend, the auxiliary pressing block 7 at the front end first contacts the plate and presses the plate to achieve stability during drilling. At the same time, the rubber material has a good coefficient of friction to avoid displacement during drilling and affect the quality.

[0033] In summary: When drilling is required on the sheet metal, the drilling parameters are transmitted to the PLC controller 3. The PLC controller 3 sends an electrical signal to move the guide rails on the operating table body 6. Then, the operator pushes the sheet metal to align with the guide rails on both sides. Simultaneously, the adjusting mechanism 4 inside the mounting housing 5 drives the drilling drive mechanism 8 to adjust the spacing according to the parameters input into the PLC controller 3. This allows the machine tool to quickly adapt to different drilling positions and hole spacing requirements, eliminating the need for frequent disassembly and adjustment of the drill bit as in traditional methods, thus improving production efficiency. Subsequently, the lifting mechanism 2 lowers the mounting housing 5 to drive the drilling drive mechanism 8 to perform drilling on the sheet metal on the operating table body 6. After drilling is completed, the lifting mechanism 2 resets the mounting housing 5, and the adjusting mechanism 4 adjusts the position of the drill bit in the drilling drive mechanism 8, avoiding frequent manual operation and greatly shortening the equipment adjustment time, making the entire production process more compact. The PLC controller 3 is electrically connected to the lifting mechanism 2, the adjusting mechanism 4, the operating table body 6, and the drilling drive mechanism 8. This technology is existing and will not be elaborated further here.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
