Description

Technical Field

[0001] This utility model relates to the field of loudspeaker manufacturing technology, specifically a drilling device for producing loudspeaker housings. Background Technology

[0002] The horn is an audio signal device in a car. During the driving process, the driver emits necessary audio signals as needed and in accordance with regulations to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. It is also used to urge the vehicle to move and transmit signals. Currently, testing devices are required in the production process of car horns.

[0003] Existing drilling devices for speaker housing production are generally inconvenient for quickly clamping housings of various sizes during use, and it is also inconvenient to reset the clamping device after drilling, thus reducing the processing efficiency of the housing and making them impractical.

[0004] To address the aforementioned problems, existing technologies provide a solution. For example, patent publication number CN220312585U discloses a drilling device for producing speaker housings, including a worktable. A support rod is fixedly connected to the top right side of the worktable, a connecting rod is fixedly connected to the top of the support rod, a telescopic rod is fixedly connected to the bottom of the connecting rod, a drill bit is fixedly connected to the output end of the telescopic rod, and a motor is fixedly connected to the front end of the top right side of the worktable. A rotating rod is fixedly connected to the output end of the motor. In this invention, the housing is placed on a workbench, and the motor, in conjunction with the rotating rod, winding roller, and rope, moves the first clamping block to fix the housing. Simultaneously, the spring is compressed, and the telescopic rod is activated to drill a hole in the housing. After drilling, the rope is loosened, and the spring force pushes the first clamping block back to its original position, thus facilitating the repositioning of the clamping device. This improves the processing efficiency of the housing and has good practicality. Existing devices only clamp the periphery of the horn when drilling holes, and the drill bit applies pressure to the horn during drilling, which can easily cause the horn to dent downwards. If the horn material does not have good resilience, the quality of the horn will decrease.

[0005] To address this, a drilling device for producing speaker housings is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a drilling device for the production of speaker housings, thereby solving the above-mentioned problems.

When the speaker on the suction cup moves towards the drilling rig, the longitudinal rack controls the drive mechanism to operate, and through the connecting block, drives the top block to extend and fit against the inner wall of the speaker. The pressure generated when the top block fits against the inner wall of the speaker controls the operation of the connecting mechanism and controls the piston plate to move within the suction cup to generate negative pressure.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. However, the embodiments described below are only some embodiments of the present utility model, and not all of them. If other embodiments are obtained by those skilled in the art without creative effort, they shall fall within the protection scope of the present utility model.

[0022] Reference Figures 1 to 4 A drilling device for producing speaker housings includes a frame 1, a lifting assembly 2, and a drill 3. It also includes a fixed platform 4, a longitudinal rack 5, a drive mechanism 6, a connecting block 7, a top block 8, a connecting mechanism 9, a piston plate 10, a suction cup 11, and a circular plate 12. The fixed platform 4 is connected to the frame 1, the longitudinal rack 5 is connected to the fixed platform 4, the drive mechanism 6 is connected to the longitudinal rack 5, the connecting block 7 is connected to the drive mechanism 6, and the top block 8 is connected to the connecting block 7. Each of the connecting blocks 7 and the top block 8 has three sets, and the spacing between the three sets of connecting blocks 7 and the top block 8 is the same. Through the above arrangement... It can ensure that the inner wall of the horn is evenly stressed, and can prevent the horn from deforming under stress. It can also protect the horn when drilling. The connecting mechanism 9 is connected to the top block 8, the piston plate 10 is connected to the connecting mechanism 9, and the suction cup 11 is connected to the piston plate 10. When the horn on the suction cup 11 moves towards the drilling machine 3, the longitudinal rack 5 controls the drive mechanism 6 to run, and drives the top block 8 to extend and fit against the inner wall of the horn through the connecting block 7. The pressure generated when the top block 8 fits against the inner wall of the horn controls the connecting mechanism 9 to run and controls the piston plate 10 to move within the suction cup 11 to generate negative pressure.

[0023] As one embodiment of this utility model, refer to Figure 3The drive mechanism 6 includes a drive gear 61, a rotating shaft 62, a receiving gear 63, a gear ring 64, a support plate 65, and a worm gear 66. The drive gear 61 engages with the longitudinal rack 5. The rotating shaft 62 is connected to the drive gear 61, the receiving gear 63 is connected to the rotating shaft 62, the gear ring 64 engages with the receiving gear 63, the support plate 65 is connected to the gear ring 64, and the worm gear 66 is connected to the support plate 65. The worm gear 66 allows the three connecting blocks 7 to move outward or inward simultaneously during the rotation of the support plate 65. The drive gear 61 and the receiving gear 63 have the same gear ratio and are symmetrically arranged about the center line of the rotating shaft 62. This arrangement allows the drive gear 61 and the receiving gear 63 to maintain balance, preventing uneven force distribution during rotation and extending the service life of the rotating shaft 62.

[0024] As one embodiment of this utility model, refer to Figure 4 The connecting mechanism 9 includes a moving sleeve 91, a fixed sleeve 92, an upper rack 93, a spur gear 94, and a lower rack 95. The moving sleeve 91 is connected to the top block 8, the fixed sleeve 92 is connected to the moving sleeve 91, the upper rack 93 is connected to the fixed sleeve 92, the spur gear 94 engages with the upper rack 93, and the lower rack 95 engages with the spur gear 94. The upper rack 93 and the lower rack 95 are symmetrical about the center of the spur gear 94. Through the above arrangement, the upper rack 93 and the lower rack 95 can maintain synchronous movement, and at the same time, the upper rack 93 and the lower rack 95 can move in opposite directions.

[0025] Working principle: During use, the user places the horn to be drilled on the fixed platform 4, and then controls the fixed platform 4 to move towards the drill 3 via the lifting component 2. As the fixed platform 4 rises, the drive gear 61 meshes with the longitudinal rack 5, thereby driving the rotating shaft 62 to rotate via the drive gear 61. When the rotating shaft 62 rotates, it drives the gear ring 64 to rotate via the connecting gear. When the gear ring 64 rotates, it drives the worm plate 66 to rotate via the support plate 65. When the worm plate 66 rotates, it drives the connecting block 7 to extend outward. When the connecting block 7 moves, it can move through the moving sleeve 91 and the fixed sleeve 92. The top block 8 moves synchronously towards the inner wall of the speaker. When the top block 8 is in contact with the inner body of the speaker, the distance between the connecting block 7 and the top block 8 gradually decreases as the connecting block 7 continues to move. This allows the moving sleeve 91 to move within the fixed sleeve 92, and simultaneously drives the upper rack 93 to mesh with the spur gear 94, thereby controlling the spur gear 94 to rotate. When the spur gear 94 rotates, it can drive the piston plate 10 to move through the lower rack 95. When the piston plate 10 moves, it can generate negative pressure in the suction cup 11. Under the action of negative pressure, it can drive the circular plate 12 to descend, thereby adsorbing the suction cup 11 onto the bottom of the speaker.

[0026] Although the embodiments of this utility model have been described in detail with reference to the accompanying drawings, those skilled in the art can make changes, modifications, substitutions and variations to these embodiments without departing from the principles and spirit of this utility model. The appended claims and their equivalents define the scope of this utility model.
