[0004] The purpose of this invention is to provide a drilling device for automotive parts, which can simultaneously drill holes in the side walls of multiple filter cartridges, thereby improving processing efficiency.

[0005] To achieve the above objectives, this utility model provides a drilling device for automotive parts, comprising multiple fixed support rods arranged circumferentially. From bottom to top, each fixed support rod has a first layer, a second layer, a third layer, and a fourth layer. The third layer is slidably connected to the fixed support rods, while the first, second, and fourth layers are fixedly connected to the fixed support rods. A lifting platform is located at the center of the second layer. Multiple radially movable drilling machines are arranged on the lifting platform along its circumferential direction. Multiple active rotating platforms, each corresponding to one of the drilling machines, are arranged on the second layer. Limiting bosses are provided on the active rotating platforms. Multiple driven rotating platforms, each corresponding to one of the active rotating platforms, are arranged on the third layer. A first cylinder is mounted on the fourth layer, connecting to and driving the third layer vertically. An upper pressure cover is provided at the bottom of the driven rotating platforms.

[0006] Preferably, the active rotary table includes a first rotating shaft and a first turntable fixed to the upper end of the first rotating shaft. The first rotating shaft is connected to the second layer plate through a first bearing.

[0007] Preferably, the bottom of the active gear ring is connected to a fixing plate via multiple downwardly converging spokes, and a stepper motor connected to the fixing plate is installed at the bottom of the first layer plate.

[0008] Preferably, a second cylinder is provided at the bottom of the second layer plate, and the cylinder shaft of the second cylinder passes through the second layer plate and is connected to the lifting platform, thereby driving the lifting platform to move vertically.

[0009] Preferably, a hydraulic cylinder is provided at the center of the lifting platform, a disc is fixedly connected to the top of the hydraulic cylinder, and multiple push handles are circumferentially hinged to the disc, with the distal end of each push handle hinged to the rear end of the drilling machine.

[0010] Preferably, the lifting platform is provided with a plurality of guide rail grooves corresponding to the drilling machine, and the bottom of the drilling machine is provided with guide rails that can slide in the guide rail grooves.

[0011] Preferably, the driven rotary table includes a second rotating shaft and a second turntable fixed to the lower end of the second rotating shaft, and the second rotating shaft is connected to the three-layer plate through a second bearing.

[0012] Preferably, the bottom surface of the second turntable is provided with an inwardly recessed positioning groove.

[0013] According to the above technical solution, this utility model provides a drilling device for automotive parts, including multiple fixed support rods arranged circumferentially. From bottom to top, each fixed support rod has a first layer, a second layer, a third layer, and a fourth layer. The third layer is slidably connected to the fixed support rods, while the first, second, and fourth layers are fixedly connected to the fixed support rods. A lifting platform is located at the center of the second layer. Multiple radially movable drilling machines are arranged on the lifting platform along its circumferential direction. Multiple active rotating platforms, each corresponding to one of the drilling machines, are arranged on the second layer. Limiting bosses are provided on the active rotating platforms. Multiple driven rotating platforms, each corresponding to one of the active rotating platforms, are arranged on the third layer. A first cylinder is mounted on the fourth layer, connecting to and driving the third layer vertically. An upper pressure cover is provided at the bottom of the driven rotating platforms.

[0014] The operation and benefits of this automotive parts drilling equipment are as follows: First, the filter cartridge to be drilled is pressed onto the limiting boss. Then, the first cylinder drives the three-layer plate downwards, causing the driven rotary table to press against the upper end of the filter cartridge. Next, the drilling machine slides outwards to drill holes in the side wall of the filter cartridge. After drilling, the active rotary table rotates at a certain angle to continue drilling until a full circle of holes is completed. Then, the lifting platform rises, driving multiple drilling machines to rise synchronously. This process is repeated to drill another full circle of holes in the previous layer, and the lifting platform continues to rise until all holes in all layers are drilled. During the rotation of the active rotary table, the driven rotary table also rotates because it is pressed against the upper end of the filter cartridge. This automotive parts drilling equipment can simultaneously drill holes in the side walls of multiple filter cartridges, improving processing efficiency.

Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figure 1-5The automotive parts drilling equipment shown includes multiple fixed support rods 1 arranged circumferentially. From bottom to top, a first layer plate 2, a second layer plate 3, a third layer plate 4, and a fourth layer plate 5 are sequentially arranged on the fixed support rods 1. The third layer plate 4 is slidably connected to the fixed support rods 1, while the first layer plate 2, the second layer plate 3, and the fourth layer plate 5 are fixedly connected to the fixed support rods 1. A lifting platform 24 is located at the center of the second layer plate 3. Multiple radially movable drilling machines 11 are arranged on the lifting platform 24 along its circumference. Multiple active rotating platforms, each corresponding to one of the drilling machines 11, are arranged on the second layer plate 3 along its circumference. Limiting bosses 10 are provided on the active rotating platforms. Multiple driven rotating platforms, each corresponding to one of the active rotating platforms, are arranged on the third layer plate 4. A first cylinder 16 is installed on the fourth layer plate 5, connecting to the third layer plate 4 and driving its vertical movement. An upper pressure cover is provided at the bottom of the driven rotating platforms.

[0027] By implementing the above technical solution, in use, the filter cartridge 12 that needs to be drilled is first pressed onto the limiting boss 10. Then, the first cylinder 16 drives the three-layer plate 4 to move downward, so that the driven rotary table presses against the upper end of the filter cartridge 12. Then, the drilling machine 11 slides outward to drill holes in the side wall of the filter cartridge 12. After drilling, the active rotary table rotates at a certain angle to continue drilling until a circle of holes is drilled. Then, the lifting platform 24 rises, driving multiple drilling machines 11 to rise synchronously. The above operation is repeated to drill another circle of holes in the circumference of the upper layer. The lifting platform 24 then rises again until all the holes in all layers are drilled. When the active rotary table rotates, the driven rotary table also rotates because it is pressed against the upper end of the filter cartridge 12. This automotive parts drilling equipment can simultaneously drill holes in the side walls of multiple filter cartridges 12, improving processing efficiency.

[0028] In this embodiment, the active rotary table includes a first rotating shaft 8 and a first turntable 9 fixed to the upper end of the first rotating shaft 8. The first rotating shaft 8 is connected to the second-layer plate 3 via a first bearing 7. A gear 6 is sleeved on the lower end of the first rotating shaft 8, and an active gear ring 20 is provided at the bottom of the second-layer plate 3, which meshes with multiple gears 6 simultaneously. The rotation of the active gear ring 20 drives multiple gears 6 to rotate synchronously, thereby driving multiple filter cartridges 12 pressed on the first turntable 9 to rotate synchronously, realizing synchronous perforation of multiple filter cartridges 12.

[0029] In this embodiment, the bottom of the active gear ring 20 is connected to a fixed plate 17 via multiple downwardly converging spokes 18, and a stepper motor 22 connected to the fixed plate 17 is mounted on the bottom of the first-layer plate 2. The stepper motor 22 drives the fixed plate 17 and the active gear ring 20 to rotate synchronously by intermittently rotating its angle.

[0030] In this embodiment, a second cylinder 21 is provided at the bottom of the second layer plate 3. The cylinder shaft of the second cylinder 21 passes through the second layer plate 3 and connects to the lifting platform 24, driving the lifting platform 24 to move vertically. The vertical movement of the lifting platform 24 is driven by the extension and retraction of the second cylinder 21, adjusting the height of the rotating hole.

[0031] In this embodiment, a hydraulic cylinder 23 is disposed at the center of the lifting platform 24. A disc 25 is fixedly connected to the top of the hydraulic cylinder 23. Multiple push handles 26 are circumferentially hinged to the disc 25, and the distal ends of the push handles 26 are hinged to the rear end of the drilling machine 11. By extending and retracting the hydraulic cylinder 23, the height of the disc 25 is adjusted, thereby pushing the drilling machine 11 radially under the push of the push handles 26 to adjust the drilling depth.

[0032] In this embodiment, the lifting platform 24 is provided with a plurality of guide rail grooves 27 corresponding to the drilling machine 11, and the bottom of the drilling machine 11 is provided with guide rails 28 that can slide in the guide rail grooves 27. The cooperation between the guide rail grooves 27 and the guide rails 28 increases the stability of the drilling machine 11.

[0033] In this embodiment, the driven rotary table includes a second rotating shaft 13 and a second turntable 15 fixed to the lower end of the second rotating shaft 13. The second rotating shaft 13 is connected to the three-layer plate 4 via a second bearing 14. This arrangement allows the second turntable 15, which is pressed against the filter cartridge 12, to rotate synchronously.

[0034] In this embodiment, the bottom surface of the second turntable 15 is provided with an inwardly recessed positioning groove 19. The positioning groove 19 is provided to fit snugly onto the upper end of the filter cartridge 12, increasing the stability of the drilling and preventing the filter cartridge 12 from shifting its position when subjected to lateral force. In addition, a rubber pad can be provided in the positioning groove 19 to increase friction.

[0035] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0036] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0037] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
