Description
Technical Field
[0001] This invention relates to the field of drilling device technology, specifically a drilling device for a children's stroller body. Background Technology
[0002] The perforation device for children's vehicles is a specialized piece of equipment used for precise drilling of holes in the vehicle body (including the chassis structure). It achieves automated processing of multiple hole specifications through CNC or mechanical transmission systems. It can simultaneously handle decorative holes on the body panels and mounting holes on the chassis load-bearing structure. Equipped with a waste collection system and hole edge deburring function, it ensures that hole processing in metal or plastic materials meets safety standards, satisfying the comprehensive needs of children's vehicle structural assembly, ventilation and weight reduction, and appearance design.
[0003] When drilling holes in the chassis of children's vehicles, a series of defects can easily occur due to insufficient rigidity of the chassis structure itself or irregular features such as grooves and depressions. When the drilling mechanism acts on these weak areas, the material around the hole will undergo local plastic deformation due to stress concentration, resulting in obvious warping of the hole edge. Insufficient support in the recessed areas can also cause drilling deviation, resulting in hole diameter deviation or ellipticity exceeding the standard. In more serious cases, it may induce hidden damage such as microcracks. These defects not only affect the assembly accuracy, but also significantly reduce the fatigue life of the chassis under dynamic loads. Summary of the Invention

Detailed Implementation
[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.
[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.
[0028] In one embodiment, see Figure 1 and Figure 2 A perforation device for a children's vehicle body includes a support platform 1, a bracket 2 fixed to the top of the support platform 1, a perforation mechanism 6 installed on the bracket 2, the perforation mechanism 6 being used to perforate the children's vehicle chassis, a plurality of clamping blocks 7 arranged in an array on the top of the support platform 1, the clamping blocks 7 being connected to a drive mechanism 4, the drive mechanism 4 being used to drive the plurality of clamping blocks 7 to move together synchronously, a support mechanism 5 being provided inside the support platform 1, the support mechanism 5 being used to provide adaptive support for the children's vehicle chassis, wherein a push rod 8 extends through the bottom of the support platform 1, the upper end of the push rod 8 extending into the support platform 1, the lower end of the push rod 8 being connected to a pushing mechanism 3, the pushing mechanism 3 being used to drive the push rod 8 to move upward, and when the push rod 8 moves upward, the push rod 8 sequentially drives the drive mechanism 4 and the support mechanism 5 to operate.
[0029] In this embodiment, when drilling holes in the stroller body (such as the stroller's chassis structure), the stroller chassis is placed on top of the support platform 1. Then, the push mechanism 3 drives the push rod 8 to move upward. As the push rod 8 moves upward, the drive mechanism 4 first drives multiple clamping blocks 7 to move closer together until all the clamping blocks 7 are tightly fitted against the side wall of the stroller chassis. The array of multiple clamping blocks 7 serves to both position and clamp and fix the stroller chassis, ensuring the stability of the stroller chassis and improving the drilling effect of the subsequent drilling mechanism 6. After the stroller chassis is fixed, the push mechanism 3 continues to drive... When push rod 8 moves upward, it drives support mechanism 5 to rotate. Support mechanism 5 provides multi-point support for the stroller chassis. For example, at locations where the stroller chassis directly contacts support platform 1, support platform 1 directly supports the stroller chassis. At locations where the stroller chassis does not contact support platform 1 (such as the groove at the bottom of the stroller chassis), when drilling mechanism 6 drills holes, it applies pressure to the stroller chassis. Since support platform 1 cannot effectively support these areas, the stroller chassis may deform locally during drilling. In this case, support mechanism 5 can support the groove of the stroller chassis. The stroller chassis acts as a support, providing adaptive support and effectively preventing deformation of the chassis caused by the drilling mechanism 6 during drilling. This provides excellent protection for the chassis. The drilling mechanism 6 includes components such as a moving assembly, mounting plate, telescopic rod, fixed plate, motor, and drill rod. The moving assembly drives the motor and drill rod horizontally via the mounting plate, telescopic rod, and fixed plate. The telescopic rod drives the motor and drill rod vertically via the fixed plate. The motor drives the drill rod to rotate, thus enabling drilling at different locations on the stroller chassis. This is existing technology and will not be elaborated further. The children's vehicle body drilling device adopts a linkage design of array-type clamping blocks 7 for synchronous positioning and multi-point support mechanism 5. While ensuring accurate positioning of the chassis, it effectively suppresses typical defects such as local plastic deformation, hole warping and micro-cracks during the drilling process through dynamic compensation support. In particular, for the weak parts of the chassis groove area, the support mechanism 5 can provide precise lifting force compensation, thereby avoiding deformation and significantly improving hole position accuracy and edge quality. The integrated design enables the positioning, clamping and support processes to be completed automatically, which significantly improves production efficiency. At the same time, it solves the processing defects caused by insufficient chassis structure rigidity or groove depression in traditional drilling processes.
[0030] Please see Figure 3The pushing mechanism 3 includes a push plate 31 fixedly connected to the bottom of the push rod 8. A plug rod 37 is fixedly fixed to the top of the push plate 31. A limiting cylinder 32 is fixedly fixed to the bottom of the support platform 1. The upper end of the plug rod 37 extends into the inside of the limiting cylinder 32 and is slidably connected to the inner wall of the limiting cylinder 32. A first elastic element 33 is provided on the outside of the plug rod 37. The two ends of the first elastic element 33 are fixedly connected to the top of the push plate 31 and the bottom of the limiting cylinder 32, respectively. A fixing component is provided inside the limiting cylinder 32. After the support mechanism 5 has finished supporting the chassis of the stroller, the fixing component is used to fix the plug rod 37.
[0031] When it is necessary to fix the stroller chassis, push plate 31 is pushed upwards. Push plate 31 drives push rod 8 to move upwards. As push rod 8 moves upwards, it first drives multiple clamping blocks 7 to move together synchronously through drive mechanism 4, thus fixing the stroller chassis. After the stroller chassis is fixed, push plate 31 continues to drive push rod 8 upwards. At this time, as push rod 8 moves upwards, support mechanism 5 provides adaptive support for the stroller chassis, thereby avoiding deformation caused during the drilling process. Furthermore, during the upward movement of push rod 8 and the support mechanism 5 supporting the stroller chassis, push rod 8 does not drive drive mechanism 4 to rotate, and the clamping force of clamping blocks 7 on the stroller chassis does not change, thus avoiding the support mechanism... 5. When supporting the child stroller chassis, the child stroller chassis is lifted upwards, which also prevents the clamping force of the clamping block 7 from increasing and causing damage to the child stroller chassis. When the support mechanism 5 has finished supporting the child stroller chassis, the fixing component has just completed the fixing of the push rod 8, thereby improving the stability of the push rod 8 and ensuring the support effect of the support mechanism 5 on the child stroller chassis. When the child stroller chassis is drilled, the fixing component is released from fixing the push rod 8. The push rod 8 automatically resets under the action of the push plate 31 and the first elastic element 33. At this time, the support mechanism 5 no longer supports the child stroller chassis, and the drive mechanism 4 drives the clamping blocks 7 to move away from each other, thereby disengaging the clamping state of the clamping blocks 7 on the child stroller chassis. The first elastic element 33 can be a spring.
[0032] Please see Figure 3 The fixing component includes a plurality of pin slots 36 arranged vertically on the side wall of the insertion rod 37, and a pin 35 passing through the side wall of the limiting cylinder 32. A second elastic member 34 is fixed on the side of the pin 35 near the limiting cylinder 32, and the other end of the second elastic member 34 is fixedly connected to the side wall of the limiting cylinder 32.
[0033] When the stroller chassis needs to be fixed, push plate 31 is pushed upward. Push plate 31 drives push rod 8 to move upward. Push rod 8 drives drive mechanism 4 and support mechanism 5 in sequence. When support mechanism 5 completes the support of stroller chassis, pin 35, under the action of second elastic element 34, automatically enters one of the pin grooves 36. At this time, pin 35 provides a limiting support for push rod 8 through pin groove 36, thereby restricting push rod 8 from moving downward, thus improving the stability of push rod 8 and ensuring the support effect of support mechanism 5 on stroller chassis. When the stroller chassis is drilled, pin 35 can be directly pulled out from pin groove 36. The second elastic element 34 can be a spring, and in order to avoid the pin 35 interfering with the upward movement of push rod 8, the end of pin 35 can be wedge-shaped.
[0034] Please see Figure 4 and Figure 5 The driving mechanism 4 includes multiple slides arranged in an array inside the support platform 1. Each slide corresponds to a clamping block 7. A slider 41 passes through the inside of each slide and is slidably connected to the slide. The upper end of the slider 41 is detachably connected to the clamping block 7, and the lower end of the slider 41 is connected to a traction component. The traction component is used to pull the slider 41, thereby causing the clamping blocks 7 to move closer together. Each slide is provided with a reset component. When the traction component stops pulling the slider 41, the reset component is used to reset the slider 41.
[0035] When fixing the stroller chassis, the push mechanism 3 drives the push rod 8 to move upward. As the push rod 8 moves upward, the traction component pulls the slider 41. Under the traction of the traction component, the slider 41 pulls the clamping block 7 to move closer until the clamping block 7 is tightly attached to the side wall of the stroller chassis. At this time, the clamping block 7 plays a positioning and clamping role for the stroller chassis, ensuring the stability of the stroller chassis and improving the drilling effect of the drilling mechanism 6 on the stroller chassis. When the stroller chassis is drilled, the push rod 8 moves downward, the traction component no longer pulls the slider 41, the slider 41 automatically resets under the action of the reset component, and the clamping blocks 7 move away from each other, thereby releasing the clamping state of the stroller chassis.
[0036] Please see Figure 5 The reset assembly includes a third elastic element 48 fixedly connected to the side wall of the slider 41, and the other end of the third elastic element 48 fixedly connected to the inner wall of the slide. A limit rod 49 is fixed inside the slide, and the limit rod 49 passes through the slider 41 and is slidably connected to the slider 41.
[0037] When fixing the stroller chassis, the push mechanism 3 drives the push rod 8 to move upward. At the same time, the push rod 8 moves upward and pulls the slider 41 through the traction component. Under the traction of the traction component, the slider 41 drives the clamping block 7 to move closer. At this time, the clamping block 7 squeezes the third elastic element 48, which is in a compressed state. The third elastic element 48 can be a spring. When the stroller chassis is punched, the traction component no longer pulls the slider 41. The third elastic element 48 releases its elastic potential energy, thereby driving the slider 41 to automatically reset. The clamping blocks 7 move away from each other, thereby releasing the clamping state on the stroller chassis. The limiting rod 49 can play a limiting role on the slider 41, effectively improving the stability of the slider 41 when it moves.
[0038] Please see Figure 4 and Figure 6 The traction assembly includes a rotating cylinder 43 rotatably connected to the bottom of the support platform 1, a push rod 8 passing through the rotating cylinder 43 and slidably connected to the rotating cylinder 43, a plurality of traction ropes 42 fixed to the outside of the rotating cylinder 43, the other ends of the plurality of traction ropes 42 being fixedly connected to the side walls of a plurality of sliders 41 respectively, a spiral groove 45 being provided at the lower end of the inner wall of the rotating cylinder 43, a vertical groove 44 being provided at the upper end of the inner wall of the rotating cylinder 43, the lower end of the vertical groove 44 being connected to the upper end of the spiral groove 45, and a protrusion 46 adapted to the spiral groove 45 and the vertical groove 44 being provided on the side wall of the push rod 8, the protrusion 46 being located inside the spiral groove 45 and slidably connected to the spiral groove 45;
[0039] When fixing the stroller chassis, the push mechanism 3 drives the push rod 8 to move upward, and the push rod 8 drives the protrusion 46 to move upward. Initially, the protrusion 46 moves inside the spiral groove 45. At this time, the protrusion 46 squeezes the rotating cylinder 43 through the spiral groove 45, and then the rotating cylinder 43 rotates in reverse. While the rotating cylinder 43 rotates, it winds up the traction rope 42. The traction rope 42 pulls the slider 41, and the slider 41 drives the clamping blocks 7 to move closer together, thus completing the clamping and fixing of the stroller chassis. When the clamping blocks 7 have completed the clamping and fixing of the stroller chassis, the protrusion 46 just moves to the upper end of the spiral groove 45 and enters the vertical groove 44. At this time, as the push rod 8 continues to move upward, the protrusion 46 will not drive the rotating cylinder 43 to rotate, and the clamping force of the clamping blocks 7 on the stroller chassis will not change. This avoids the phenomenon that the support mechanism 5 lifts the stroller chassis upward when supporting the stroller chassis, and also avoids the damage to the stroller chassis caused by the continued increase in the clamping force of the clamping blocks 7.
[0040] Please see Figure 5 A sliding plate 410 is fixed on the side wall of the clamping block 7. The sliding plate 410 passes through the slider 41 and is slidably connected to the slider 41. A bolt 47 passes through the top of the slider 41. The top of the sliding plate 410 is provided with threaded holes 411 that are evenly distributed and adapted to the bolts 47.
[0041] When fixing the chassis of the stroller, the sliding plate 410 can also drive the clamping block 7 to move, thereby adjusting the initial position of the clamping block 7. This allows the clamping block 7 to fix stroller chassis of different specifications, effectively improving the applicability of the device. When the initial position of the clamping block 7 is adjusted, the sliding plate 410 can be fixed by the cooperation of the bolt 47 and the threaded hole 411, thereby ensuring the stability of the clamping block 7.
[0042] Please see Figure 7 The support mechanism 5 includes multiple guide cylinders 54 fixedly connected to the bottom of the support platform 1. A support rod 51 passes through the upper end of the guide cylinder 54. The upper end of the support rod 51 passes through the top of the support platform 1 and is flush with the outer top of the support platform 1. A stop block 52 is fixed to the outside of each support rod 51. A fourth elastic element 53 is fixed to the bottom of the stop block 52. The lower end of the fourth elastic element 53 is fixedly connected to the top of the guide cylinder 54. The guide cylinders 54 are connected through a connecting pipe 55. One of the guide cylinders 54 is connected to an air intake assembly, which is used to inflate the inside of the guide cylinder 54.
[0043] When drilling holes in the stroller chassis, the stroller chassis is placed on top of the support platform 1. The push mechanism 3 drives the push rod 8 upwards. Simultaneously, the push rod 8 moves upwards, first causing multiple clamping blocks 7 to move closer together via the drive mechanism 4, until all clamping blocks 7 are tightly fitted against the side walls of the stroller chassis. Then, as the push rod 8 continues to move upwards, air is injected into one of the guide cylinders 54 through the air intake assembly. The increased air pressure inside the guide cylinder 54 compresses the support rod 51, causing it to move upwards. Since the guide cylinders 54 are connected by a connecting pipe 55, the gas inside the guide cylinder 54 also flows into the remaining air cylinders 56 through the connecting pipe 55, thus... The remaining support rods 51 can move upward synchronously. When the upper end of the support rod 51 contacts the stroller chassis, the stroller chassis applies pressure to the support rod 51, thereby restricting the upward movement of the support rod 51. However, since gas can flow between multiple guide cylinders 54, the remaining support rods 51 that are not in contact with the stroller chassis will continue to move upward until all the support rods 51 are in contact with the stroller chassis. At this time, the multiple support rods 51 play an adaptive support role for the stroller chassis, ensuring the stability of the stroller chassis and avoiding the deformation phenomenon generated during the drilling process of the stroller chassis. The fourth elastic element 53 can be a spring, which can play a reset role for the support rod 51 through the stop block 52.
[0044] Please see Figure 7 and Figure 8The air intake assembly includes a pneumatic cylinder 56 fixedly connected to the top of the support platform 1. A piston 514 is slidably connected inside the pneumatic cylinder 56. A pneumatic rod 510 is fixed to the bottom of the piston 514. The pneumatic rod 510 passes through the bottom of the pneumatic cylinder 56 and is slidably connected to the bottom of the pneumatic cylinder 56. A stop plate 511 is fixed to the bottom of the pneumatic rod 510. A fifth elastic element 512 is fixed to the top of the stop plate 511. The upper end of the fifth elastic element 512 is fixedly connected to the bottom of the pneumatic cylinder 56. An exhaust pipe 57 is connected above the piston 514 and on the side wall of the pneumatic cylinder 56. The other end of the exhaust pipe 57 is connected to one of the guide cylinders 54.
[0045] When drilling holes in the stroller chassis, the stroller chassis is placed on top of the support platform 1. The push mechanism 3 drives the push rod 8 to move upward. As the push rod 8 moves upward, it first drives multiple clamping blocks 7 to move together synchronously through the drive mechanism 4 until the clamping blocks 7 are all tightly attached to the side wall of the stroller chassis. Then, as the push rod 8 continues to move upward, it squeezes the abutment plate 511. The abutment plate 511 drives the piston 514 to move upward through the pneumatic rod 510. The piston 514 squeezes the gas above it, so that the gas inside the pneumatic cylinder 56 can enter one of the guide cylinders 54 through the exhaust pipe 57, and achieve adaptive support for the stroller chassis. The fifth elastic element 512 can be a spring. The fifth elastic element 512 can play a reset role for the piston 514 through the abutment plate 511 and the support rod.
[0046] Please see Figure 5 and Figure 8 Below the piston 514 and on the side wall of the air cylinder 56, there is an air inlet pipe 59 and an air outlet pipe 58. One of the clamping blocks 7 has an air outlet hole 513 on its side wall, and the clamping block 7 has an air chamber inside, which is connected to the air outlet hole 513 and the air outlet pipe 58.
[0047] When the push rod 8 presses the abutment plate 511, the abutment plate 511 drives the piston 514 to move upward through the pneumatic rod 510. At this time, a negative pressure is formed below the piston 514, and the outside gas enters the pneumatic cylinder 56 through the air inlet pipe 59. When the children's stroller chassis is drilled, the push rod 8 no longer presses the abutment plate 511. The abutment plate 511 automatically resets under the action of the fifth elastic element 512, thereby driving the piston 514 to move downward through the pneumatic rod 510. The piston 514 squeezes the gas below it, which in turn causes the gas inside the pneumatic cylinder 56 to enter the air chamber inside one of the clamping blocks 7 through the air outlet pipe 58. This gas is finally discharged from the air outlet 513 and acts on the surface of the children's stroller chassis, thus cleaning the waste generated during the drilling process. In order to ensure unidirectional gas flow, both the air inlet pipe 59 and the air outlet pipe 58 are equipped with one-way valves.
[0048] Working principle: When drilling holes in the stroller body (such as the stroller chassis structure), the stroller chassis is placed on top of the support platform 1. Then, the push plate 31 drives the push rod 8 to move upward. The push rod 8 drives the protrusion 46 to move upward. Initially, the protrusion 46 moves inside the spiral groove 45. At this time, the protrusion 46 squeezes the rotating cylinder 43 through the spiral groove 45, and the rotating cylinder 43 rotates in reverse. While the rotating cylinder 43 is rotating, it winds up the traction rope 42. The traction rope 42 pulls the slider 41. The slider 41 drives the clamping blocks 7 to move closer together, thus clamping and fixing the chassis of the stroller. After the clamping blocks 7 have finished clamping and fixing the chassis, the protrusion 46 moves to the upper end of the spiral groove 45 and enters the vertical groove 44. At this time, as the push rod 8 continues to move upward, the protrusion 46 will not drive the rotating cylinder 43 to rotate, and the clamping force of the clamping blocks 7 on the chassis of the stroller will not change. At this time, the push rod 8 presses the abutment plate 511, and the abutment plate 511 drives the piston 514 to move upward through the pneumatic rod 510. During the upward movement, piston 514 compresses the gas above it, allowing the gas inside the pneumatic cylinder 56 to enter one of the guide cylinders 54 through the exhaust pipe 57. The increased gas pressure inside the guide cylinder 54 compresses the support rod 51, causing it to move upward. Since the guide cylinders 54 are connected by a connecting pipe 55, the gas inside the guide cylinder 54 also flows into the remaining pneumatic cylinders 56 through the connecting pipe 55, allowing the remaining support rods 51 to move upward synchronously. When the upper end of the support rod 51 contacts the stroller chassis, the stroller chassis applies pressure to the support rod 51, thus restricting its upward movement. However, since the gas can flow between multiple guide cylinders 54, the remaining support rods 51 that are not in contact with the stroller chassis will continue to move upward until all support rods 51 are in contact with the stroller chassis. At this point, the multiple support rods 51 provide adaptive support for the stroller chassis, ensuring its stability and preventing deformation during the drilling process.
[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
