Description

Technical Field

[0001] This utility model relates to the field of drilling device technology, and in particular to a high-efficiency drilling device for automotive parts. Background Technology

[0002] The high-efficiency drilling device for automotive parts is a specialized processing equipment that integrates mechanical transmission, automated control and intelligent detection technologies. Through a high-precision spindle system, automated feed mechanism and intelligent control system, it achieves high-speed and precise drilling operations for automotive parts. Its core function is to significantly improve processing efficiency, compress the single-hole processing time to the second level and reduce the scrap rate.

[0003] For example, CN212917738U discloses a drilling device for automotive parts, including an operating table, a collection box fixedly connected to the bottom of the operating table, a slide rail inside the operating table, a slider slidably connected inside the slide rail, a chuck fixedly connected to the top of the slider, a bidirectional threaded rod inserted inside the slider, the left end of the bidirectional threaded rod passing through the operating table, and a power gear sleeved on the outer surface of the part of the bidirectional threaded rod located outside the operating table.

[0004] However, in existing technologies, when fixing thin-walled parts, the unreasonable cylinder distribution design of pneumatic or hydraulic clamps leads to excessive local stress on the parts. In addition, the poor rigidity of thin-walled materials causes the parts to dent or twist and deform. At the same time, traditional fixing methods cannot provide sufficient positioning support points to offset the impact of cutting forces, causing vibration. Furthermore, direct contact between rigid clamps and thin-walled parts can easily damage their surfaces. Moreover, existing fixing devices lack self-adaptive capabilities and cannot cope with part size deviations. Forced clamping generates internal stress, ultimately leading to problems such as uneven stress, unstable positioning, surface damage, and deformation of thin-walled parts during the fixing process, which seriously affects drilling accuracy and part quality. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art by proposing a high-efficiency drilling device for automotive parts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a high-efficiency drilling device for automotive parts, comprising an operating table, a first servo adjustment mechanism fixedly connected to the upper part of the operating table, a drilling mechanism mounted on the side of the first servo adjustment mechanism, a second servo adjustment mechanism fixedly connected to the surface of the operating table, an mounting platform fixedly connected to the upper part of the second servo adjustment mechanism, a limit mechanism fixedly connected to the upper part of the mounting platform, the limit mechanism comprising a slide rail, a slider slidably connected inside the slide rail, and a lead screw rotatably connected inside the slide rail, the lead screw being threadedly connected to the slider, a fixing frame fixedly connected to the upper part of the slider, a first cylinder fixedly connected to the bottom of the fixing frame, an mounting frame fixedly connected to the bottom of the first cylinder, two second cylinders fixedly connected to the inner wall of the mounting frame, the two second cylinders being mirror images of each other, and a clamping plate fixedly connected to the end of the second cylinder.

[0007] Preferably, a servo motor is fixedly connected to the end of the slide rail, and the output end of the servo motor is fixedly connected to the end of the lead screw.

[0008] Preferably, a first limiting rod is fixedly connected to the upper part of the mounting bracket, and the first limiting rod is slidably inserted into the fixed bracket.

[0009] Preferably, the mounting bracket has two connecting plates fixedly connected to its side, and the two connecting plates are symmetrically distributed on both sides of the mounting bracket.

[0010] Preferably, a second limiting rod is inserted into the surface of the connecting plate, a second clamping plate is fixedly connected to the bottom of the second limiting rod, a spring is fixedly connected to the surface of the second clamping plate, and one end of the spring is fixedly connected to the connecting plate.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the servo motor in the limiting mechanism drives the lead screw to rotate, causing the slider to slide along the slide rail, thus achieving flexible adjustment of the position of the first clamping plate. This adapts to thin-walled materials of different sizes, improving versatility. The combination of the first and second cylinders allows the first clamping plate to clamp the thin-walled material step-by-step and precisely from both vertical and horizontal directions, avoiding excessive local pressure. Simultaneously, the first limiting rod ensures the stability of the mounting frame's movement, preventing offset during clamping. This structure not only solves the problem of part deformation caused by uneven cylinder distribution in traditional clamping devices but also avoids damage to thin-walled parts through adaptive adjustment, improving positioning stability. This significantly improves the accuracy and quality of drilling thin-walled parts, enhancing the practicality and processing efficiency of the device.

[0012] 2. In this utility model, the fixing effect of thin-walled parts is further optimized through the innovative combination of the mounting bracket, connecting plate, second limiting rod, second clamping plate, and spring. When the first cylinder pushes the mounting bracket down, the second clamping plate contacts the bottom wall of the thin-walled material first. At this time, the spring is compressed and undergoes elastic deformation, converting its own elastic potential energy into a continuous and uniform thrust, so that the second clamping plate always fits against the bottom wall of the thin-walled material, forming a stable support surface. The plug-in structure of the second limiting rod and the connecting plate ensures that the second clamping plate maintains vertical movement during the spring's force application, preventing tilting and misalignment.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0017] Example 1: As Figures 1-4As shown, this utility model provides a high-efficiency drilling device for automotive parts, including an operating table 1. A first servo adjustment mechanism 2 is fixedly connected to the upper part of the operating table 1. A drilling mechanism 3 is mounted on the side of the first servo adjustment mechanism 2. A second servo adjustment mechanism 4 is fixedly connected to the surface of the operating table 1. A mounting platform 5 is fixedly connected to the upper part of the second servo adjustment mechanism 4. A limit mechanism 6 is fixedly connected to the upper part of the mounting platform 5. The limit mechanism 6 includes a slide rail 61, a slider 62 is slidably connected inside the slide rail 61, and a lead screw 64 is rotatably connected inside the slide rail 61. The lead screw 64 is threadedly connected to the slider 62. A fixed frame 65 is fixedly connected to the upper part of the slider 62. A first cylinder 66 is fixedly connected to the bottom of the fixed frame 65. A mounting frame 68 is fixedly connected to the bottom of the first cylinder 66. Two second cylinders 69 are fixedly connected to the inner wall of the mounting frame 68. The two second cylinders 69 are mirror images of each other, and a first clamping plate 610 is fixedly connected to the end of the second cylinder 69. A servo motor 63 is fixedly connected to the end of the slide rail 61. The output end of the servo motor 63 is fixedly connected to the end of the lead screw 64. A first limiting rod 67 is fixedly connected to the upper part of the mounting frame 68. The first limiting rod 67 is slidably inserted into the fixed frame 65.

[0018] The specific settings and functions of this embodiment are described below. The thin-walled material to be drilled is placed on the upper part of the mounting platform 5. According to the size of the thin-walled material, the servo motor 63 drives the lead screw 64 to rotate, thereby driving the slider 62 to slide along the slide rail 61, and thus adjusting the position of the first clamping plate 610 so that the thin wall of the thin-walled material is located between the two first clamping plates 610. The first cylinder 66 pushes the first clamping plate 610 downward, and then the second cylinder 69 pushes the first clamping plate 610 to clamp and fix the side of the thin-walled material. The servo motor 63 adjusts the position of the first clamping plate 610 to facilitate the fixation of different materials by the first clamping plate 610, while avoiding excessive pressure or tension on the thin wall of the thin-walled material.

[0019] The coordinated design of the second servo adjustment mechanism 4, the mounting platform 5, and the limiting mechanism 6 effectively solves the problem of fixing thin-walled parts. Specifically, the servo motor 63 in the limiting mechanism 6 drives the lead screw 64 to rotate, causing the slider 62 to slide along the slide rail 61, enabling flexible adjustment of the position of the first clamping plate 610. This adapts to thin-walled materials of different sizes, improving versatility. The combination of the first cylinder 66 and the second cylinder 69 allows the first clamping plate 610 to clamp the thin-walled material step-by-step and precisely from both vertical and horizontal directions, avoiding excessive local pressure. Simultaneously, the first limiting rod 67 ensures the stability of the mounting frame 68's movement, preventing offset during clamping. This structure not only solves the problem of part deformation caused by uneven cylinder distribution in traditional clamping devices but also avoids damage to thin-walled parts through adaptive adjustment, improving positioning stability. This significantly improves the accuracy and quality of drilling thin-walled parts, enhancing the practicality and processing efficiency of the device.

[0020] Example 2: Figure 3 and Figure 4 As shown, two connecting plates 611 are fixedly connected to the side of the mounting bracket 68. The two connecting plates 611 are symmetrically distributed on both sides of the mounting bracket 68. A second limiting rod 612 is inserted into the surface of the connecting plate 611. A second clamping plate 613 is fixedly connected to the bottom of the second limiting rod 612. A spring 614 is fixedly connected to the surface of the second clamping plate 613. One end of the spring 614 is fixedly connected to the connecting plate 611.

[0021] The overall effect of this embodiment is that the innovative combination of mounting bracket 68, connecting plate 611, second limiting rod 612, second clamping plate 613, and spring 614 further optimizes the fixing effect of thin-walled parts. When cylinder 66 pushes mounting bracket 68 downward, clamping plate 613 first contacts the bottom wall of thin-walled material. At this time, spring 614 is compressed and undergoes elastic deformation, converting its elastic potential energy into a continuous and uniform thrust, so that clamping plate 613 always fits against the bottom wall of thin-walled material, forming a stable support surface. The plug-in structure of second limiting rod 612 and connecting plate 611 ensures that clamping plate 613 remains vertically moving during the application of force by spring 614, preventing tilting and misalignment. This design effectively compensates for the shortcomings of traditional fixing methods in providing insufficient support for the bottom of thin-walled parts, preventing vibration or displacement of the parts due to cutting forces. Simultaneously, the buffering characteristics of spring 614 prevent damage to the parts from rigid contact. Through the synergistic effect of multiple components, the stability and machining accuracy of drilling thin-walled parts are significantly improved, ensuring part quality. The method of use and working principle of this device: Place the thin-walled material to be drilled on the upper part of the mounting platform 5. According to the size of the thin-walled material, the servo motor 63 drives the lead screw 64 to rotate, thereby driving the slider 62 to slide along the slide rail 61, and then adjusting the position of the first clamping plate 610 so that the thin wall of the thin-walled material is located between the two first clamping plates 610. The first cylinder 66 pushes the first clamping plate 610 to move downward. Then, the second cylinder 69 pushes the first clamping plate 610 to clamp and fix the side of the thin-walled material. The servo motor 63 adjusts the position of the first clamping plate 610 to facilitate the fixation of different materials by the first clamping plate 610, while avoiding excessive pressure or tension on the thin wall of the thin-walled material. During the process of cylinder 66 pushing mounting bracket 68 downward, clamp 613 first contacts the bottom wall of thin-walled material. Then, spring 614 is compressed, generating thrust on clamp 613. Clamp 613 holds and fixes the bottom wall of thin-walled material, ensuring the stability of thin-walled material during drilling.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
