Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically a door lock bracket hole position testing device. Background Technology

[0002] Car door lock brackets are key components of car door lock systems, playing a crucial role in connecting the door lock to the car door or body. They need to possess sufficient strength and stability to ensure the door lock functions properly, guaranteeing the vehicle's safety and reliability. Furthermore, the positional accuracy of the door lock bracket also affects the door lock's closing performance and lifespan.

[0003] Traditional methods for inspecting the hole positions of door lock brackets primarily rely on manual visual inspection and simple measuring tools such as calipers and rulers. However, these methods have several drawbacks. First, manual visual inspection has limited accuracy, making it difficult to accurately judge subtle deviations in the hole positions. This can easily lead to substandard products entering subsequent production stages or the market, causing problems such as difficulty in door lock installation, smooth opening, or even malfunction. This not only affects production efficiency but may also lead to a poor user experience and potential safety hazards for customers. Second, while traditional measuring tools can improve inspection accuracy to some extent, their operation is cumbersome and inefficient. On large-scale production lines, accurately measuring each pair of door lock brackets individually requires significant manpower and time costs, severely restricting production progress and overall efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-8 This utility model provides a technical solution: a door lock bracket hole position detection device, including a frame 1, a conveyor 2 on the frame 1, and a carrier 3 for conveying workpieces installed on the conveyor 2; a first detection component 4 is provided on one side of the conveyor 2 on the frame 1; a detection positioning mechanism 6 is also provided on the frame 1, and a second detection component 5 is provided on both sides of the detection positioning mechanism 6; a shifting mechanism 7 is provided on the frame 1, and the shifting mechanism 7 is located between the first detection component 4 and the second detection component 5.

[0023] Specifically, the door lock bracket hole position detection equipment includes a frame 1, on which a conveyor 2 is mounted, and on the conveyor 2 is a carrier 3 for conveying workpieces. The conveyor 2 carries and transports the workpieces, which are placed on the carrier 3, which is mounted on the conveyor 2 and moves with it. A first detection component 4 is located on one side of the conveyor 2 on the frame 1, used for preliminary hole position detection of the conveyed workpieces; each workpiece passes through the first detection component 4. The frame 1 also includes a detection positioning mechanism 6, with second detection components 5 on both sides of the detection positioning mechanism 6. A shifting mechanism 7 is located between the first detection component 4 and the second detection components 5. After the workpiece passes through the shifting mechanism 7, it is moved to the detection positioning mechanism 6, where the second detection components 5 perform more precise hole position detection.

[0024] Specifically, both the first detection component 4 and the second detection component 5 are existing technologies, and both include a CCD camera. In security systems, images are currently mainly generated by CCD cameras. CCD is short for charge-coupled device, which can convert light into electric charge and store and transfer the charge. It can also extract the stored charge to change the voltage. Therefore, it is an ideal CCD camera element. CCD cameras made of it are widely used because they are small in size, light in weight, unaffected by magnetic fields, and have the characteristics of being resistant to vibration and impact.

[0025] During use, the door lock bracket can be precisely positioned and clamped by the detection and positioning mechanism 6, ensuring the workpiece's position is accurate and stable during inspection, laying the foundation for high-precision inspection. The coordinated work of the first detection component 4 and the second detection component 5 enables the inspection of the door lock bracket's holes from different angles and positions, comprehensively covering all key points of the holes. This effectively avoids minor deviations that might be missed by manual visual inspection or simple measuring tools, making the inspection results more accurate and reliable. This ensures that only products with qualified hole position accuracy can enter subsequent production stages or the market, guaranteeing smooth installation and reliable use of automotive door locks, and preventing door lock malfunctions caused by hole position deviations. Simultaneously, the carrier 3 on the conveyor 2 can sequentially place multiple door lock bracket workpieces and automatically transport them to the inspection position, realizing automated continuous operation of the inspection process. This eliminates the need for manual placement and inspection of workpieces, significantly saving manpower and time costs. The shifting mechanism 7 flexibly transfers workpieces between the first detection component 4 and the second detection component 5, allowing for rapid switching between different inspection stations, further improving inspection efficiency and meeting the speed requirements of large-scale production lines.

[0026] In the embodiments provided by this utility model, the detection and positioning mechanism 6 includes a mounting frame 66 mounted on a frame 1. Clamping rods 62 are slidably connected to both sides of the mounting frame 66, and a first cylinder 63 is provided on the mounting frame 66 to drive the two clamping rods 62 to slide. Positioning frames 61 are also provided on both sides of the mounting frame 66. A support plate 76 is also slidably connected to the mounting frame 66, and a second cylinder 64 is mounted on the support plate 76. The output end of the second cylinder 64 is connected to the bottom of the first cylinder 63. An extension block 65 is provided on the top of each clamping rod 62. That is, after the workpiece is mounted on the positioning frame 61, the first cylinder 63 drives the two clamping rods 62 to move closer together, positioning the workpiece. Then, the second cylinder 64 drives the first cylinder 63 downwards, and the extension block 65 performs secondary positioning of the workpiece, ensuring accurate positioning of the workpiece during the detection process.

[0027] In the embodiments provided by this utility model, the shifting mechanism 7 includes a shifting plate 71 mounted on a frame 1, and a bearing plate 76 mounted on the shifting plate 71. Clamping portions 77 are provided on both sides of the bearing plate 76, and a power unit for driving the bearing plate 76 to move is provided on the shifting plate 71. The power unit includes a motor mounted on the shifting plate 71, and a swing arm 73 is rotatably connected to the shifting plate 71. The motor's power shaft is connected to the swing arm 73. A mounting plate is provided on the bearing plate 76 via a guide member, and a guide rod 74 is rotatably connected to the mounting plate and mounted on the swing arm 73. A guide groove 72 is provided on the shifting plate 71, and the guide rod 74 moves within the guide groove 72. The guide component includes a guide block 78 slidably connected to the shift plate 71. The guide block 78 has a groove, and a guide post is slidably connected within the groove. The mounting plate and the support plate 76 are connected via the guide post. The swing arm 73 has a clearance groove 75, and a guide rod 74 is movably connected within the clearance groove 75. When the swing arm 73 rotates, the guide post slides within the groove. Specifically, in the initial state, when the motor shaft rotates, it drives the swing arm 73 to rotate. At this time, the swing arm 73 moves within the guide groove 72 via the guide rod 74, which drives the support plate 76 to slide. The clamping portions 77 on both sides of the support plate 76 then clamp the workpiece. More specifically, the clamping portion 77 on the left side of the support plate 76 clamps the workpiece from the carrier 3 on the conveyor 2, while the clamping portion 77 on the right side of the support plate 76 clamps away the workpiece that has already been inspected on the detection and positioning mechanism 6, separating and unloading it, repeating the cycle.

[0028] In the embodiments provided by this utility model, the carrier 3 has an installation space 31, through which the workpiece is placed on the carrier 3. The shape and size of the installation space 31 are adapted to the workpiece. The workpiece is placed on the carrier 3 through the installation space 31, which can play a preliminary positioning and fixing role for the workpiece, keeping it stable during transportation and facilitating subsequent inspection operations.

[0029] In the embodiment provided by this utility model, a first output section 8 and a second output section 9 are provided on the frame 1. The first output section 8 and the second output section 9 are respectively arranged at appropriate positions on the frame 1. The first output section 8 is used to output workpieces that pass the inspection, and the second output section 9 is used to output workpieces that fail the inspection. After the workpieces have been inspected, according to the inspection results, the workpieces are transported to the designated positions through the corresponding output sections to realize the classification and subsequent processing of the workpieces.

[0030] In the embodiments provided by this utility model, the clamping part 77 includes a third cylinder mounted on the support plate 76, and a gripper is provided at the output end of the third cylinder. When it is necessary to clamp the workpiece, the third cylinder operates, driving the gripper to close and tightly clamp the workpiece; when it is necessary to release the workpiece, the third cylinder operates in the opposite direction, driving the gripper to open and release the workpiece. In this way, the clamping and releasing of the workpiece can be conveniently realized, ensuring the stability of the workpiece during the displacement and inspection process.

[0031] It should be noted that all electrical equipment involved in this application can be powered by batteries or external power sources.
