Detailed Implementation

[0030] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0031] Please see Figures 1-6 This invention provides a drilling device for a speaker cover assembly, including a worktable 1. Support frames 2 and clamping assemblies are provided on both the front and rear sides of the worktable 1. An adjusting assembly is provided between the two support frames 2. An electric push rod 3 is provided at the moving end of the adjusting assembly. A drilling motor 4 is provided at the output end of the electric push rod 3. A drill bit 5 is provided at the output end of the drilling motor 4. The upper surface of the worktable 1 has a chip removal hole 6, and the clamping end of the clamping assembly extends into the chip removal hole 6. A receiving device is provided below the chip removal hole 6. The assembly includes mounting brackets 7 on both the left and right sides of the workbench 1. A threaded sleeve 8 is rotatably mounted on the middle of the mounting bracket 7 via a bearing. A driven gear 9 is mounted on the threaded sleeve 8. A first screw 10 is threaded inside the threaded sleeve 8. A cleaning plate 11 is mounted at one end of the first screw 10. A linkage rod 12 is rotatably mounted below the workbench 1. Both ends of the linkage rod 12 are equipped with driving gears 13. The linkage rod 12 is driven by a first motor 14, and the driving gears 13 mesh with the driven gears 9.

[0032] In this embodiment, the clamping assembly can securely clamp the speaker cover assembly to prevent shaking during drilling; the adjusting assembly between the two support frames 2 can flexibly adjust the drilling position; the electric push rod 3 at the moving end of the adjusting assembly can control the drilling depth; the drilling motor 4 at the output end of the electric push rod 3 drives the drill bit 5 to perform drilling operations; the chip removal hole 6 on the upper surface of the worktable 1 facilitates chip falling; the clamping end of the clamping assembly extends into the chip removal hole 6 without affecting chip falling; the collecting assembly below the chip removal hole 6 can collect the chips in a concentrated manner; the threaded sleeve 8, the driven gear 9, the first screw 10, and other components on the mounting brackets 7 on the left and right sides of the worktable 1, together with the linkage rod 12, the driving gear 13, and the first motor 14, can drive the cleaning plate 11 to move and clean the chips on the worktable 1 surface, effectively solving the problem that chip accumulation affects drilling accuracy and efficiency and is inconvenient for centralized cleaning.

[0033] Furthermore, the adjustment assembly includes two positioning rods 15, a second screw 16, and an adjustment seat 17. The adjustment seat 17 has a threaded groove 18 and a positioning groove 19. The two positioning rods 15 are respectively fixedly connected to the corresponding support frame 2 and are located on the two support frames 2, and also pass through the corresponding positioning groove 19. The second screw 16 is rotatably connected to the corresponding support frame 2 and is located on the two support frames 2. The second screw 16 is driven by a second motor. The second screw 16 is also threadedly connected to the adjustment seat 17 and is located in the threaded groove 18. The electric push rod 3 is disposed below the adjustment seat 17.

[0034] In this embodiment, by driving the second screw 16 to rotate by the second motor, the horizontal movement distance of the adjusting seat 17 can be precisely controlled, thereby accurately adjusting the position of the electric push rod 3 and the drilling component to meet the drilling requirements at different positions and improve the flexibility and accuracy of drilling.

[0035] Furthermore, the collection assembly includes a collection box 20 and two slides 21. Sliders 22 are provided on both sides of the collection box 20. The collection box 20 is slidably connected to the corresponding slide 21 through the slides 22 and is located between the two slides 21 and below the chip discharge hole 6. The two slides 21 are fixedly connected to the worktable 1 and are located below the worktable 1.

[0036] In this embodiment, when the collection box 20 is full of debris, it can be quickly pulled out from the slide 21 for cleaning, and then easily put back after cleaning, which improves the efficiency of debris cleaning and facilitates centralized processing of debris.

[0037] Furthermore, the clamping assembly includes a clamping plate 23 and a hydraulic cylinder 24. Both ends of the clamping plate 23 are provided with limit rods 25. The clamping plate 23 is fixedly connected to the hydraulic cylinder 24 and is located at the output end of the hydraulic cylinder 24. The hydraulic cylinder 24 is provided on both the front and rear sides of the worktable 1, and the limit rod 25 passes through the worktable 1.

[0038] In this embodiment, the hydraulic cylinder 24 provides strong clamping power, and the clamping plate 23 is fixedly connected to the hydraulic cylinder 24. Under the drive of the hydraulic cylinder 24, the speaker cover assembly can be stably clamped.

[0039] Furthermore, the front end face of the cleaning plate 11 is V-shaped, and the two cleaning plates 11 are arranged opposite each other in the V shape and abut against the upper end face of the workbench 1.

[0040] In this embodiment, the unique shape design allows the cleaning plate 11 to better gather and push debris during movement, concentrating the debris at the debris discharge hole 6, making the cleaning effect more significant, and further preventing debris from accumulating on the workbench 1 and affecting the drilling operation.

[0041] Furthermore, the number of external teeth of the driven gear 9 is greater than the number of external teeth of the driving gear 13, and the driven gear 9 is located above the driving gear 13.

[0042] In this embodiment, when the first motor 14 drives the driving gear 13 to rotate, the rotational speed of the threaded sleeve 8 is reduced and the torque is increased by meshing with the driven gear 9, thereby driving the first screw 10 to move more stably, thus ensuring the smoothness of the movement of the cleaning plate 11 and improving the reliability of cleaning debris.

[0043] Furthermore, both ends of the cleaning plate 11 are provided with auxiliary rods 26, and both ends of the mounting bracket 7 are provided with auxiliary sleeves 27, with the auxiliary rods 26 inserted into the auxiliary rods 26.

[0044] In this embodiment, the auxiliary rod 26 and the auxiliary sleeve 27 serve as auxiliary support and guide to prevent the cleaning plate 11 from shaking or shifting during movement.

[0045] Furthermore, a plurality of support legs 28 are inclinedly arranged below the workbench 1, and the plurality of support legs 28 are arranged symmetrically in pairs.

[0046] In this embodiment, the tilting arrangement increases the stability of the device, enabling it to better withstand various forces generated during operation; the symmetrical arrangement in pairs makes the center of gravity of the device more evenly distributed, further improving the stability of the device and reducing shaking during operation.

[0047] Furthermore, a transverse reinforcing rod 29 is provided between the two transversely oriented support legs 28, and two longitudinal reinforcing rods 30 are provided between the two longitudinally oriented support legs 28.

[0048] In this embodiment, the transverse reinforcing rod 29 and the longitudinal reinforcing rod 30 can effectively disperse the force borne by the device, prevent the support leg 28 from deforming or being damaged during use, and extend the service life of the device.

[0049] When using the speaker cover assembly drilling device of this embodiment, the speaker cover assembly to be drilled is placed on the worktable 1, and its position is adjusted to a suitable drilling position. Then, the two hydraulic cylinders 24 are controlled to work, and the hydraulic cylinders 24 push the clamping plate 23 to move towards and clamp the speaker cover assembly. The second motor is started, and the second motor drives the second screw 16 to rotate. The adjusting seat 17 moves along the axial direction of the second screw 16, driving the electric push rod 3, the drilling motor 4, and the drill bit 5 to move. The drill bit 5 is adjusted to above the position to be drilled. The electric push rod 3 is started, and the electric push rod 3 pushes the drilling motor 4 and the drill bit 5 downward. At the same time, the drilling motor 4 is started, and the drilling motor 4 drives the drill bit 5 to rotate, performing the drilling operation on the speaker cover assembly. Some of the debris generated during the drilling process falls through the dropper on the worktable 1. The debris falls into the collection assembly below through the chip hole 6, while another portion of the debris falls onto the upper surface of the workbench 1. After drilling is completed, the workpiece is removed, and the first motor 14 is then controlled to operate. The first motor 14 drives the linkage rod 12 to rotate, and the driven gear 9 rotates slowly, driving the threaded sleeve 8 to rotate. As the threaded sleeve 8 rotates, the first screw 10 drives the cleaning plate 11 to move on the workbench 1 surface, pushing the residual debris on the workbench 1 surface and causing it to fall into the chip hole 6. When the two cleaning plates 11 approach each other, due to the V-shaped structure, some debris will directly enter the chip hole 6, while some will be concentrated at the front and rear edges of the workbench 1. At this time, the concentrated debris can be swept into the chip hole 6 by a brush, and all of these debris will enter the collection box 20. Finally, the collection box 20 is processed.

[0050] Please see Figure 7 The present invention also provides a method for drilling holes in a speaker cover assembly, applied to the aforementioned speaker cover assembly drilling device, comprising the following steps:

[0051] S1: Place the speaker cover assembly that needs to be drilled on the workbench 1, adjust its position so that it is in a suitable drilling position, and then control the two hydraulic cylinders 24 to work. The hydraulic cylinders 24 push the clamping plate 23 to move towards the speaker cover assembly and clamp it.

[0052] S2: Start the second motor, which drives the second screw 16 to rotate. The adjusting seat 17 will move along the axial direction of the second screw 16, driving the electric push rod 3, the drilling motor 4 and the drill bit 5 to move, and adjusting the drill bit 5 to the position above where drilling is required.

[0053] S3: Start the electric push rod 3, the electric push rod 3 pushes the drilling motor 4 and the drill bit 5 to move downward, start the drilling motor 4, the drilling motor 4 drives the drill bit 5 to rotate, and perform drilling operation on the speaker cover assembly;

[0054] S4: After drilling is completed, control the electric push rod 3 to retract the drilling motor 4 and the drill bit 5 upwards, control the second motor to reset the adjusting seat 17 to the initial position, and control the hydraulic cylinder 24 to release the clamping plate 23, thus obtaining the speaker cover assembly with completed drilling.
