Description

Technical Field

[0001] This utility model relates to the field of drilling technology for wooden decorative panels, and more specifically, it relates to a drilling device for wooden decorative panels. Background Technology

[0002] In existing wood decorative panel drilling technology, although various types of drilling devices are available on the market, they still have certain limitations in actual use. Specifically, some drilling devices usually have a protective device between the output end of the drive assembly and the drill rod, designed to prevent the drill rod from breaking under high load or jamming conditions, or to prevent the motor from being damaged due to instantaneous overload. While these protective devices improve the safety of equipment operation to a certain extent, their structure is usually relatively simple and lacks the ability to flexibly adjust the overload threshold under different usage scenarios. This design defect can bring many adverse effects in practical applications. For example, when drilling on wood boards of different materials, thicknesses, or densities, the required drilling resistance and torque may vary significantly. The fixed protective device cannot be adjusted according to the actual working conditions, resulting in the protective threshold being too high or too low. When the threshold is set too low, the equipment may accidentally trigger the protective mechanism under normal load, leading to accidental stoppage or work interruption, affecting production efficiency. Conversely, if the threshold is too high, the protective mechanism may not be activated in time when encountering abnormal jamming, which can easily cause the drill rod to break, the motor to be damaged, or even cause safety accidents.

[0003] In addition, although some equipment has incorporated adjustable components in its structural design to achieve flexible control of the overload protection threshold, most of these improvements are limited to relatively basic mechanical coordination. The overall structure is still relatively simple and lacks sufficient stability and reliability. When the equipment is running for a long time, frequently changing materials, or under adverse working conditions such as external vibration and impact, such adjustment mechanisms are prone to causing changes in the adjusted protection threshold, making the protection device unable to be used correctly. This not only affects the service life and stability of the punching device, but also increases the maintenance frequency and operational risks, thereby affecting the continuity and safety of the entire production line.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a drilling device for wooden decorative panels, which has the following advantages:

[0017] 1. Through an innovative overload protection threshold adjustment mechanism, this design effectively solves the technical problem of existing technologies being unable to flexibly adjust the overload protection threshold according to actual usage needs. The design employs a sophisticated combination of components such as a transmission rod, transmission sleeve, adjustment sleeve, moving plate, moving block, movable groove, movable spring, transmission block, and transmission groove to achieve precise adjustment of the overload protection threshold. When the drill rod jams, the transmission rod and transmission groove encounter resistance, causing the inner wall of the transmission groove to press against the outer wall of the transmission block. Relying on the rounded corner design of the outer wall of the transmission block and the inner wall of the transmission groove, the transmission block can slide out of the transmission groove and slide into the inner side of the movable groove, compressing the movable spring. Ultimately, the device completely disengages from the transmission slot, allowing the drive assembly to rotate freely with the transmission sleeve and other components, achieving no-load protection. More importantly, operators can easily adjust the protection threshold according to actual work needs. By adjusting the forward and reverse rotation of the sleeve, the magnitude of the thrust applied by the movable spring to the transmission block is changed, thereby precisely controlling the threshold required for the transmission block to disengage from the transmission slot. This flexible adjustment mechanism greatly improves the adaptability and safety of the equipment, enabling it to be specifically adjusted according to different hardness plates and different working conditions, effectively solving the technical defects of traditional drilling device protective devices that are simple in structure and cannot be flexibly adjusted.

[0018] 2. The design of multiple locking mechanisms, including a spring, tension spring, mating rod, mating hole, locking sleeve, locking rod, locking groove, locking frame, and locking plate, ensures structural stability after the protection threshold is adjusted. After the threshold adjustment is completed, the tension spring pulls the locking plate inward, causing the locking plate to drive the locking rod into the corresponding locking groove, forming the first layer of locking. At the same time, the spring pushes the locking sleeve to reset, and the inner wall of the locking sleeve limits the outer wall of the locking plate, preventing the locking plate and locking rod from sliding outward, forming the second layer of locking. The rotation of the mating plate causes the mating hole and the mating rod to misalign, and the mating rod limits and supports the locking sleeve. On one side of the mating plate, a third locking mechanism is formed to prevent the locking sleeve from sliding. This multi-locking protection mechanism effectively prevents the equipment from becoming loose or falling off due to vibration or external forces during operation, ensuring the long-term stability and reliability of the protection threshold setting. It completely solves the technical defects of some existing equipment that can adjust the overload protection threshold but have simple structures and low stability. This allows the equipment to maintain stable protection performance even under high-intensity and long-term continuous working conditions, greatly improving the safety, reliability and work efficiency of drilling in wooden decorative panels.

[0028] Please see Figures 1-5 A drilling device for wooden decorative panels includes a drill rod 1, a transmission rod 2 fixedly connected to the top of the drill rod 1, a transmission sleeve 3 rotatably sleeved on the outer side of the transmission rod 2, a mating plate 4 rotatably sleeved on the outer side of the transmission sleeve 3, a locking sleeve 5 slidably sleeved on the outer side of the transmission sleeve 3, an adjusting sleeve 6 rotatably sleeved on the outer side of the transmission sleeve 3, a mating hole 7 on the mating plate 4, a mating rod 8 fixedly connected to one side of the locking sleeve 5, a locking bracket 9 fixedly connected to one side of the adjusting sleeve 6, a follower sleeve 10 movably sleeved inside the adjusting sleeve 6, a moving groove 11 inclinedly formed inside the transmission sleeve 3, a moving plate 12 slidably sleeved in the moving groove 11, and a moving block 13 fixedly connected to one side of the moving plate 12. The inner side of the movable block 13 has a movable groove 14, and the movable groove 14 is movably equipped with a movable spring 15. One end of the movable spring 15 is connected to the inner wall of the movable groove 14, and the other end of the movable spring 15 is connected to a transmission block 16. The outer side of the transmission rod 2 has a transmission groove 17, and the transmission block 16 is inserted into the transmission groove 17. The locking rod 18 is slidably provided in the locking frame 9. The outer wall of the transmission sleeve 3 has multiple locking grooves 19. One end of the locking rod 18 is connected to a locking plate 20, and the other end of the locking rod 18 is inserted into the locking groove 19. The outer side of the follower sleeve 10 is fixedly equipped with an adjusting block 21. The inner side of the adjusting sleeve 6 has a spirally opened adjusting groove 22, and the adjusting block 21 is slidably located in the adjusting groove 22.

[0029] A frame 23 is provided below the drill rod 1. A longitudinal slide rail 24 is symmetrically and detachably provided above the frame 23. A movable frame 25 is movably provided on the frame 23. A longitudinal movement cylinder 26 is detachably provided at the bottom of the movable frame 25. The longitudinal movement cylinder 26 is slidably installed on the longitudinal slide rail 24.

[0030] The top of the movable frame 25 is symmetrically provided with a horizontal slide rail 27, and a sliding frame 28 is provided on the movable frame 25. The bottom of the sliding frame 28 is detachably provided with a horizontal movement cylinder 29, which is slidably installed on the horizontal slide rail 27.

[0031] A guide rail 30 is provided above the sliding frame 28, and a drive assembly 31 is slidably provided on one side of the guide rail 30. The drive assembly 31 is slidably connected to the guide rail 30, and the output end of the drive assembly 31 is connected to the top of the transmission sleeve 3.

[0032] A detachable placement platform 32 is provided on top of the frame 23.

[0033] In this embodiment, when the equipment is used for drilling, the plate is first placed on the placement table 32 and fixed by an external fixing device. Then, the longitudinal movement cylinder 26 is opened simultaneously, causing the movable frame 25 to slide along the longitudinal slide rail 24, thereby adjusting the longitudinal position of the drill rod 1. After the longitudinal position of the drill rod 1 is properly adjusted, the longitudinal movement cylinder 26 is closed. Then, the transverse movement cylinder 29 is opened simultaneously, causing the sliding frame 28 to slide along the transverse slide rail 27, thereby adjusting the transverse position of the drill rod 1. After the transverse position of the drill rod 1 is properly adjusted, the transverse movement cylinder 29 is closed. Then, the drive assembly 31 is opened, causing the drive assembly 31 to rotate the transmission sleeve 3 connected to the output end. The transmission sleeve 3 then rotates the inner moving groove 11. The moving groove 11 then rotates the moving block 13 through the inner moving plate 12. The inner movable groove 14 will rotate, thereby driving the movable spring 15 and the transmission block 16 to rotate. Then, the transmission block 16 drives the transmission rod 2 to rotate through the transmission groove 17, causing the transmission rod 2 to drive the drill rod 1 to rotate. Then, the drive assembly 31 will drive the drill rod 1 and other components to move down along the guide rail 30 to drill holes in the plate. When the drill rod 1 gets stuck, the transmission rod 2 and the transmission groove 17 encounter resistance, causing the inner wall of the transmission groove 17 to press against the outer wall of the transmission block 16. Due to the rounded corner design of the outer wall of the transmission block 16 and the inner wall of the transmission groove 17, the transmission block 16 slides out of the transmission groove 17 and gradually slides into the inner side of the movable groove 14, causing the transmission block 16 to press against the movable spring 15 on one side, and then causing the transmission block 16 to completely disengage from the transmission groove 17. This allows the drive assembly 31 to drive the transmission sleeve 3 and other components to rotate without load, achieving no-load protection, preventing the drill rod 1 from breaking and preventing the motor from being overloaded and damaged.

[0034] Please see Figures 3-5 As a further implementation of the overall equipment: a matching spring 33 is movably sleeved on the outside of the matching rod 8. One end of the matching spring 33 is connected to the locking sleeve 5, and the other end of the matching spring 33 is in contact with the matching plate 4.

[0035] A tension spring 34 is movably sleeved on the outer side of the locking rod 18, and the two ends of the tension spring 34 are connected to the locking plate 20 and the locking frame 9 respectively.

[0036] A follower groove 35 is provided on one side of the follower sleeve 10, and a follower plate 36 is slidably provided in the follower groove 35. The follower plate 36 is fixedly connected to one side of the moving block 13.

[0037] More specifically, when the overload protection threshold needs to be adjusted according to actual requirements, firstly, rotate the mating plate 4 so that the mating plate 4 drives the mating hole 7 to rotate to a position concentric with the mating rod 8. Then, push the locking sleeve 5. The locking sleeve 5 will drive one side of the mating rod 8 to slide into the mating hole 7, and the locking sleeve 5 will cooperate with the mating plate 4 to squeeze the mating spring 33, so that the locking sleeve 5 no longer limits the outer wall of the locking plate 20. Then, rotate the adjusting sleeve 6 in the forward direction. The adjusting sleeve 6 will drive one side of the locking frame 9 to rotate in the forward direction. Then, the locking frame 9 will drive the locking rod 18, the locking plate 20, and the tension spring 34 to rotate in the forward direction. Then, the inner wall of the locking groove 19 will squeeze one end of the locking rod 18. Due to the rounded corner design at the edge of the inner wall of the locking groove 19, the locking rod 18... One end of the locking rod 18 slides out of the locking slot 19, and the other end of the locking rod 18 drives the locking plate 20 to slide outward, causing the locking plate 20 to stretch the tension spring 34 outward. At the same time, the adjusting sleeve 6 drives the inner spirally opened adjusting groove 22 to rotate in the forward direction. Then the adjusting block 21 slides in the adjusting groove 22. Due to the cooperation of the follower plate 36 and the follower groove 35, the rotation of the follower sleeve 10 is limited. Then the follower sleeve 10 will drive the adjusting block 21 to slide, and the follower sleeve 10 will push one side of the moving block 13 to move, so that the moving block 13 drives the movable groove 14, the movable spring 15 and the transmission block 16 to move. The moving block 13 will drive the other side of the moving plate 12 to slide along the inclined moving groove 11, so that the moving plate 12 drives the moving block 13 to converge inward. The moving block 13 will cause the follower plate 36 to slide inward along the follower groove 35. Then, the distance between the inner wall of the movable groove 14 and one side of the transmission block 16 will decrease, causing the movable spring 15 to be compressed to a certain extent. Then, the thrust applied by the movable spring 15 to the transmission block 16 will increase, so that the side wall of the transmission block 16 needs to withstand more force to disengage from the transmission groove 17 and trigger the protection threshold. When it is necessary for the transmission block 16 to disengage from the transmission groove 17 with only a small force, the adjusting sleeve 6 can be rotated in the reverse direction according to the above steps. When the appropriate protection threshold is adjusted, stop rotating the adjusting sleeve 6. At this time, the locking frame 9 will drive the locking rod 18 and other components to rotate to the position corresponding to the corresponding locking groove 19. Then, the tension spring 34 will pull the locking plate 20 to slide inward, so that... The locking plate 20 drives the locking rod 18 to slide and reset. Then, one end of the locking rod 18 inserts into the corresponding locking slot 19. Then, the locking sleeve 5 is released, and the cooperating spring 33 pushes the locking sleeve 5 to slide and reset. Then, the locking sleeve 5 drives one side of the cooperating rod 8 to slide and reset. When the cooperating spring 33 is fully reset, the cooperating rod 8 no longer passes into the cooperating hole 7. Then, the cooperating plate 4 is rotated again, so that the cooperating plate 4 drives the cooperating hole 7 to rotate to a position that does not correspond to the cooperating rod 8. Then, the cooperating rod 8 limits and supports the locking sleeve 5 to one side of the cooperating plate 4, so that the locking sleeve 5 will not slide. Then, the inner wall of the locking sleeve 5 limits the outer wall of the locking plate 20, so that the locking plate 20 and the locking rod 18 cannot slide outward. Then, the locking rod 18 and the locking slot 19 cooperate to lock the locking frame 9.This prevents the locking bracket 9 and adjusting sleeve 6 from rotating accidentally, thus ensuring the structural stability after the protection threshold is adjusted and guaranteeing stable equipment operation.

[0038] In summary, when using or operating the equipment: First, place the sheet metal on the placement table 32 and secure it using external fixing devices. Then, simultaneously open the longitudinal movement cylinder 26, causing the movable frame 25 to slide along the longitudinal slide rail 24, adjusting the longitudinal position of the drill rod 1. Once the longitudinal position of the drill rod 1 is properly adjusted, close the longitudinal movement cylinder 26. Then, simultaneously open the transverse movement cylinder 29, causing the sliding frame 28 to slide along the transverse slide rail 27, adjusting the transverse position of the drill rod 1. Once the transverse position of the drill rod 1 is properly adjusted, close the transverse movement cylinder 29. Then, open the drive assembly 31, causing the drive assembly 31 to rotate the transmission sleeve 3 connected to the output end. The transmission sleeve 3 then rotates the inner moving groove 11, which in turn rotates the moving block 13 via the inner moving plate 12. The moving block 13 drives the inner movable groove 14 to rotate, thereby driving the movable spring 15 and the transmission block 16 to rotate. Then, the transmission block 16 drives the transmission rod 2 to rotate through the transmission groove 17, causing the transmission rod 2 to drive the drill rod 1 to rotate. Then, the drive assembly 31 drives the drill rod 1 and other components to move down along the guide rail 30 to drill holes in the plate. When the drill rod 1 gets stuck, the transmission rod 2 and the transmission groove 17 encounter resistance, causing the inner wall of the transmission groove 17 to press against the outer wall of the transmission block 16. Due to the rounded corner design of the outer wall of the transmission block 16 and the inner wall of the transmission groove 17, the transmission block 16 slides out of the transmission groove 17 and gradually slides into the inner side of the movable groove 14, causing the transmission block 16 to press against the movable spring 15 on one side, and then causing the transmission block 16 to completely disengage from the transmission groove 17. This allows the drive assembly 31 to drive the transmission sleeve 3 and other components to rotate without load, achieving no-load protection, preventing the drill rod 1 from breaking and preventing the motor from being overloaded and damaged.

[0039] When the overload protection threshold needs to be adjusted according to actual requirements, first rotate the mating plate 4 so that the mating plate 4 drives the mating hole 7 to rotate to a position concentric with the mating rod 8. Then push the locking sleeve 5, which will cause one side of the mating rod 8 to slide into the mating hole 7. The locking sleeve 5 will also cooperate with the mating plate 4 to press against the mating spring 33, so that the locking sleeve 5 no longer limits the outer wall of the locking plate 20. Then rotate the adjusting sleeve 6 in the forward direction, which will cause one side of the locking frame 9 to rotate in the forward direction. The locking frame 9 will then cause the locking rod 18, the locking plate 20, and the tension spring 34 to rotate in the forward direction. Then the inner wall of the locking groove 19 will press against one end of the locking rod 18. Due to the rounded corner design at the edge of the inner wall of the locking groove 19, the end of the locking rod 18 will... The locking rod 18 slides out of the locking slot 19, and the other end of the locking rod 18 drives the locking plate 20 to slide outward, causing the locking plate 20 to stretch the tension spring 34 outward. At the same time, the adjusting sleeve 6 drives the inner spirally opened adjusting groove 22 to rotate in the forward direction. Then the adjusting block 21 slides in the adjusting groove 22. Due to the cooperation of the follower plate 36 and the follower groove 35, the rotation of the follower sleeve 10 is limited. Then the follower sleeve 10 will drive the adjusting block 21 to slide, and the follower sleeve 10 will push one side of the moving block 13 to move, so that the moving block 13 drives the movable groove 14, the movable spring 15 and the transmission block 16 to move. The moving block 13 will drive the other side of the moving plate 12 to slide along the inclined moving groove 11, so that the moving plate 12 drives the moving block 13 to converge inward. Block 13 will cause the follower plate 36 to slide inward along the follower groove 35. Then, the distance between the inner wall of the movable groove 14 and one side of the transmission block 16 will decrease, causing the movable spring 15 to be compressed to a certain extent. Then, the thrust applied by the movable spring 15 to the transmission block 16 will increase, so that the side wall of the transmission block 16 needs to withstand more force to disengage from the transmission groove 17 and trigger the protection threshold. When it is necessary for the transmission block 16 to disengage from the transmission groove 17 with only a small force, the adjusting sleeve 6 can be rotated in the reverse direction according to the above steps. When the appropriate protection threshold is adjusted, stop rotating the adjusting sleeve 6. At this time, the locking bracket 9 will drive the locking rod 18 and other components to rotate to the position corresponding to the corresponding locking groove 19. Then, the tension spring 34 will pull the locking plate 20 to slide inward, so that... The locking plate 20 drives the locking rod 18 to slide and reset. Then, one end of the locking rod 18 inserts into the corresponding locking slot 19. Then, the locking sleeve 5 is released, and the cooperating spring 33 pushes the locking sleeve 5 to slide and reset. Then, the locking sleeve 5 drives one side of the cooperating rod 8 to slide and reset. When the cooperating spring 33 is fully reset, the cooperating rod 8 no longer passes into the cooperating hole 7. Then, the cooperating plate 4 is rotated again, so that the cooperating plate 4 drives the cooperating hole 7 to rotate to a position that does not correspond to the cooperating rod 8. Then, the cooperating rod 8 limits and supports the locking sleeve 5 to one side of the cooperating plate 4, so that the locking sleeve 5 will not slide. Then, the inner wall of the locking sleeve 5 limits the outer wall of the locking plate 20, so that the locking plate 20 and the locking rod 18 cannot slide outward. Then, the locking rod 18 and the locking slot 19 cooperate to lock the locking frame 9.This prevents the locking bracket 9 and adjusting sleeve 6 from rotating accidentally, thus ensuring the structural stability after the protection threshold is adjusted and guaranteeing stable equipment operation.
