Description

Technical Field

Cars can meet people's needs for self-driving travel and transportation. In the process of automobile manufacturing, many small automobile parts need to be drilled.

[0003] At present, the automobile parts punching devices in the existing technology are equipped with clamping tools for limiting the position of automobile parts during use. However, due to the wide variety of automobile parts that need to be punched, such as chassis parts and assembly machines, all of which need to be punched, this leads to some problems in the punching process of traditional automobile parts punching devices.

[0004] For example, in the prior art, due to the lack of an efficient and adaptive clamping mechanism that can adapt to it, parts face many problems during the drilling operation. During the drilling process, the axial force, torque, vibration and other factors exerted by the drill bit will act together on the parts. Due to the lack of effective adaptive clamping, the parts are difficult to be stably fixed in the exact position and are prone to displacement or shaking. This displacement will not only cause deviations in the drilling position, making it difficult for the hole size to meet the design standards, but also cause the verticality and flatness of the hole to fail to meet the requirements, thereby seriously affecting the drilling accuracy.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The adaptive fixing device designed in this invention can adaptively clamp and secure automotive parts of varying shapes and sizes. The elastic unit within the adaptive fixing device, along with its internal piston plate, first return spring, and piston rod, cooperates to enable the adaptive clamping head to automatically adjust its position and force based on the automotive part's shape, effectively reducing displacement and shaking of the part during drilling. Furthermore, the clamping structure between the wedge block and the wedge-shaped hole further enhances the stability of the fixation, ensuring accurate drilling position, standardized hole diameter, and satisfactory verticality and flatness, significantly improving drilling accuracy.

[0028] 2. The arrangement of the lifting and rotating member in the present invention provides greater flexibility and rationality for drilling holes in automotive parts. The second servo motor drives the crossbar to rotate, which, through the meshing of the second active bevel gear and the second driven bevel gear, drives the half screw to rotate, causing the lifting seat to rise. When the lifting seat rises to a certain height, the half screw rotates idly. At this time, as the lifting seat continues to rise, the drive gear and the gear ring begin to mesh, driving the clamping plate to rotate, and thus rotating the automotive part. This design allows the automotive part to rotate after separation from the lifting plate, avoiding the influence of the lifting plate on the rotation of the automotive part. It can adapt to drilling requirements at different angles and positions, greatly improving the adaptability and efficiency of the processing.

[0029] 3. The lifting member in the fixing mechanism of the present invention adopts a combined structure of a guide rail, a slide seat, a scissor rod and an electric push rod. The height of the lifting plate can be easily adjusted by extending and retracting the electric push rod, thereby quickly adjusting the height of the automobile parts. In addition, the first servo motor drives the first active bevel gear to rotate, which engages with the first driven bevel gear, drives the threaded rod to rotate, and causes the movable seat to slide on the slide rod to achieve horizontal clamping of the automobile parts. These operations are simple and convenient, reduce the labor intensity of workers, and improve production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A lifting and rotating member 45 is installed on the surface of the adaptive fixing member 44 for rotating when drilling holes in automobile parts.

[0047] Reference Figure 2 、 Figure 3 as well as Figure 4 As shown, the adaptive fixing member 44 includes two second fixing plates 441 fixedly mounted on both sides of the top of the first fixing plate 41.

A first driving bevel gear 449 is fixedly mounted on the output end of the first servo motor 448. The first driving bevel gear 449 is meshedly connected to the two first driven bevel gears 447.

[0050] In this embodiment, the first servo motor 448 is started, and its output end drives the first active bevel gear 449 to rotate, meshing with the first driven bevel gear 447, driving the threaded rod 442 to rotate, causing the movable seat 443 to slide on the slide rod 4401, driving the support plate 444 and the clamping plate 445 to approach the automobile parts for clamping, thereby realizing automatic clamping of the automobile parts, simplifying the operation, and improving work efficiency.

[0051] Reference Figure 2 、 Figure 3 、 Figure 5 as well as Figure 6 As shown, the elastic unit 446 includes a plurality of piston cylinders 4461 installed through one side of the clamping plate 445. A piston plate 4462 is slidably installed inside the piston cylinder 4461. A first return spring 4463 is fixedly installed on one side of the piston plate 4462, and one end of the first return spring 4463 is fixedly connected to the inner wall of the piston cylinder 4461. A piston rod 4464 is fixedly installed on the other side of the piston plate 4462. One end of the piston rod 4464 passes through the piston cylinder 4461 and extends to the outside of the piston cylinder 4461.

[0052] An adaptive clamping head 4465 is provided at one end of the piston rod 4464 located outside the piston cylinder 4461. A connecting thread 4466 is provided on the surface of the piston rod 4464 located outside the piston cylinder 4461. The piston rod 4464 is threadedly connected to a limit cover 4467 via the connecting thread 4466. The limit cover 4467 is used to limit the position of the adaptive clamping head 4465. The adaptive clamping head 4465 and the piston rod 4464 are rotationally connected.

[0053] In this embodiment, when the adaptive clamping head 4465 contacts the surface of the automotive part, the piston rod 4464 contracts into the piston cylinder 4461, compressing the first return spring 4463, so that the adaptive clamping head 4465 can adaptively adjust the position and force according to the surface shape of the part, so as to adapt to automotive parts of different shapes, ensure the stability and reliability of clamping, and avoid the problem of loose clamping caused by uneven surface of the part.

[0054] Reference Figure 6 、 Figure 7 as well as Figure 8As shown, strip plates 4468 are fixedly installed on both sides of the interior of the piston cylinder 4461, and a plurality of wedge-shaped holes 4469 are opened on adjacent sides of the two strip plates 4468, and clamping grooves 44601 are opened on both sides of the piston plate 4462, and first installation cavities 44602 are opened on both sides of the interior of the piston plate 4462, and telescopic sleeves 44603 are fixedly installed inside the two first installation cavities 44602, and the telescopic ends of the telescopic sleeves 44603 pass through the first installation cavities 44602 and extend into the interior of the clamping grooves 44601, and the telescopic ends of the telescopic sleeves 44603 are fixedly installed with wedge blocks 44604, and the wedge blocks 44604 are clamped to the wedge-shaped holes 4469;

[0055] A mounting plate 44605 is fixedly mounted on the surface of the telescopic end of the telescopic sleeve 44603. A second return spring 44606 is fixedly mounted on one side of the mounting plate 44605. One end of the second return spring 44606 is fixedly connected to the inner wall of the first mounting cavity 44602.

[0056] In this embodiment, during the contraction of the piston rod 4464, the piston plate 4462 slides in the piston cylinder 4461. When the wedge block 44604 is aligned with the wedge hole 4469, the wedge block 44604 is engaged with the wedge hole 4469 under the action of the telescopic sleeve 44603 and the second return spring 44606, thereby further fixing the position of the piston plate 4462. The engagement structure between the wedge block 44604 and the wedge hole 4469 enhances the fixing effect of the elastic unit 446, thereby preventing the piston rod 4464 from accidentally sliding during the drilling process and improving the stability of the clamping.

[0057] The force of the second return spring 44606 is smaller than the force of the first return spring 4463 , and the clamping head can automatically return to its original position after being separated from the automobile part.

[0058] Reference Figure 5 、 Figure 9 as well as Figure 10 As shown, the lifting and rotating member 45 includes two strip-shaped mounting holes 451 opened on the surfaces of the two support plates 444, and a second mounting cavity 452 is opened inside the support plates 444 and at the bottom of the strip-shaped mounting holes 451. A second servo motor 453 is installed at the bottom of one side of the support plate 444. The output end of the second servo motor 453 passes through the support plate 444 and extends into the interior of the second mounting cavity 452. A crossbar 454 is fixedly installed at the output end of the second servo motor 453, and one end of the crossbar 454 passes through the second mounting cavity 452 and extends to the bottom of one side of the support plate 444.

[0059] A second driving bevel gear 455 is fixedly mounted on the surface of the crossbar 454 located inside the second mounting cavity 452. A half screw 456 is rotatably mounted on the top of the inner cavity of the strip-shaped mounting hole 451. The bottom end of the half screw 456 passes through the support plate 444 and extends into the interior of the second mounting cavity 452. A second driven bevel gear 457 is fixedly mounted on one end of the half screw 456 located inside the second mounting cavity 452. The second driven bevel gear 457 and the second driving bevel gear 455 are meshedly connected. A lifting seat 4501 is threadedly connected to the surface of the half screw 456. The lifting seat 4501 is rotatably connected to the clamping plate 445 via a bearing.

[0060] A reset plate 458 is slidably mounted on the surface of the half screw 456, and a third reset spring 459 is fixedly mounted on the top of the inner cavity of the strip-shaped mounting hole 451. The bottom end of the third reset spring 459 is fixedly connected to the top of the reset plate 458.

[0061] In this embodiment, the second servo motor 453 is started, and its output end drives the cross bar 454 to rotate. The second driving bevel gear 455 on the cross bar 454 engages with the second driven bevel gear 457 at the end of the half screw 456, causing the half screw 456 to rotate, driving the lifting seat 4501 to rise on the vertical slide rail 4504. At the same time, the third return spring 459 is compressed, allowing the automobile parts to be separated from the lifting plate 42 to prevent the lifting plate 42 from contacting the automobile parts and affecting subsequent rotation.

[0062] Reference Figure 5 as well as Figure 9 As shown, a driving gear 4502 is fixedly mounted on one end of the crossbar 454 outside the support plate 444, and a gear ring 4503 is fixedly mounted on one side of the clamping plate 445, and the driving gear 4502 and the gear ring 4503 are meshedly connected;

[0063] In this embodiment, when the lifting seat 4501 rises to a certain level, the driving gear 4502 on the crossbar 454 engages with the gear ring 4503 on one side of the clamping plate 445, driving the clamping plate 445 to rotate, thereby rotating the automobile parts to realize the rotation function of the automobile parts, and multi-angle drilling can be performed, thereby improving the processing flexibility and applicability of the device.

[0064] Reference Figure 9 As shown, vertical slide rails 4504 are fixedly installed on both sides of the strip-shaped mounting hole 451, and the two vertical slide rails 4504 are installed diagonally. Second slide grooves 4505 are opened on both sides of the lifting seat 4501 and the reset plate 458. The lifting seat 4501 and the reset plate 458 are slidably connected to the vertical slide rails 4504 through the second slide grooves 4505.

[0065] In this embodiment, the lifting seat 4501 and the reset plate 458 slide on the vertical slide rail 4504 through the second slide groove 4505 to ensure their stability during the ascending and descending process.

[0066] Reference Figure 6 as well as Figure 7 As shown, first sliding grooves 44607 are provided on all four sides of the surface of the piston plate 4462, and transverse slide rails 44608 are fixedly installed on all four sides of the interior of the piston cylinder 4461. The piston plate 4462 is slidably connected to the transverse slide rails 44608 through the first sliding grooves 44607;

[0067] In this embodiment, the piston plate 4462 slides on the transverse slide rail 44608 through the first slide groove 44607 to ensure smooth and stable sliding in the piston cylinder 4461.

[0068] Reference Figure 3 As shown, a slide bar 4401 is fixedly installed on both sides between the two second fixed plates 441, and one end of the slide bar 4401 passes through the movable seat 443 and is slidably connected thereto;

[0069] In this embodiment, the sliding rod 4401 passes through the movable base 443 and is slidably connected thereto, providing guidance and support for the sliding of the movable base 443 .

[0070] Reference Figure 2 as well as Figure 11 As shown, the lifting member 43 includes a plurality of guide rails 431 fixedly mounted on one side of the lifting plate 42 adjacent to the first fixed plate 41. Slide seats 432 are slidably mounted on both sides of the surface of the plurality of guide rails 431. Two scissor rods 433 are hingedly connected between the plurality of slide seats 432. A fixing rod 434 is fixedly mounted on one side adjacent to the two scissor rods 433. Two electric push rods 435 are hingedly mounted on one side of the top of the first fixed plate 41, and the telescopic ends of the two electric push rods 435 are hingedly connected to the fixing rod 434.

[0071] In this embodiment, the electric push rod 435 is started, and its telescopic end pushes the fixed rod 434, so that the scissor rod 433 is expanded or contracted with the cooperation of the slide 432 and the guide rail 431, thereby realizing the lifting and lowering of the lifting plate 42 to adjust the height of the automobile parts to adapt to different drilling depth requirements.

[0072] Working Principle: When drilling automobile parts, the automobile part is first placed on the lifting plate 42, and the electric push rod 435 is activated. The telescopic end of the electric push rod 435 pushes the fixed rod 434, causing the scissor rod 433 to expand or contract under the cooperation of the slide 432 and the guide rail 431, thereby adjusting the height of the lifting plate 42 and adjusting the automobile part to the appropriate processing position;

[0073] Next, the first servo motor 448 is started, and the output end of the first servo motor 448 drives the first active bevel gear 449 to rotate, and the first active bevel gear 449 is engaged with the first driven bevel gear 447, driving the threaded rod 442 to rotate. Since the movable seat 443 is threadedly connected to the threaded rod 442 and slides on the slide rod 4401, the two movable seats 443 will move relative to each other, driving the support plate 444 and the clamping plate 445 to approach the automobile part. When the adaptive clamping head 4465 contacts the surface of the automobile part, the piston rod 4464 will contract into the piston cylinder 4461, compressing the first return spring 4463. At the same time, the wedge block 44604 will be engaged with the wedge hole 4469 under the action of the telescopic sleeve 44603 and the second return spring 44606, thereby realizing adaptive clamping and fixation of the automobile part.

[0074] During the drilling process, if the angle of the automobile part needs to be adjusted, the second servo motor 453 is started, and the output end of the second servo motor 453 drives the cross bar 454 to rotate. The second active bevel gear 455 on the cross bar 454 engages with the second driven bevel gear 457 at the end of the half screw 456, causing the half screw 456 to rotate, thereby causing the lifting seat 4501 to rise on the half screw 456. As the lifting seat 4501 rises, the automobile part gradually separates from the lifting plate 42. When the lifting seat 4501 rises to a certain extent, the half screw 456 begins to idle, and at this time the driving gear 4502 and the gear ring 4503 just enter a meshing state. The driving gear 4502 drives the gear ring 4503 to rotate, and then the clamping plate 445 drives the automobile part to rotate, thereby realizing drilling processing at different angles.

[0075] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
