Therefore, they should not be construed as limitations on this utility model.

[0028] Throughout this specification, reference to "an embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment is included in at least one embodiment of this application. Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0029] Example 1, please refer to Figures 1-6 The present invention provides the following technical solution: See Figure 1 and Figure 3 A workpiece drilling inspection device includes an inspection bracket 1, a workpiece 3, and an electrical control box 2 mounted on the inspection bracket 1, and includes multiple auxiliary handles 4.

[0030] The inspection bracket 1 is used to position and support the workpiece and detect the drilling position of the workpiece 3. By inserting a cylindrical component with a sensor into the hole on the workpiece 3, the diameter accuracy and positional deviation are detected. The sensor transmits the collected signals to the electrical control box 2 in real time. The electrical control box 2 analyzes and processes the received signals to determine whether the workpiece drilling meets the standard. At the same time, the data is uploaded to the cloud management system through a wireless module to realize timely feedback and quality traceability in the production process, ensuring that each process is under control. The auxiliary handle 4 is used to move the position of the inspection bracket 1. The auxiliary handle 4 at different positions provides a force point, allowing the inspection bracket 1 to flexibly adjust its position in three-dimensional space to meet adjustment and inspection needs. The electrical control box 2 is responsible for receiving and integrating the detection data from the various sensors on the inspection bracket 1, determining whether the workpiece drilling is qualified, and sending instructions to the execution mechanism to determine whether to proceed to the next processing step or to reject the current unqualified workpiece, ensuring the continuity and quality of production.

[0031] The detection bracket 1 includes a support plate 11, on which a lifting detection component 13, a positioning bolt 14, a side hole detection component 15, and a bottom hole detection rod 17 are respectively provided. Multiple corner positioning rods 16 are installed on the support plate 11. Two positioning proximity sensors 18 are also symmetrically installed on the support plate 11. Support legs 12 are rectangularly installed at the bottom of the support plate 11. Two auxiliary handles 4 are symmetrically installed on the support plate 11.

[0032] See Figure 5 and Figure 6 The support plate 11 is the main load-bearing structure, and the rectangular support legs 12 at the bottom provide stable support for the support plate 11. The lifting detection component 13 is the main body for detecting higher holes. The lifting detection component 13 detects higher holes to avoid blind spots caused by height differences. The positioning bolt 14 positions the workpiece 3 to ensure that the workpiece 3 is in the correct orientation during the detection process, restricts the lateral movement of the workpiece 3, and avoids displacement caused by vibration or external force during the detection process, thereby affecting the detection accuracy. The side hole detection component 15 detects the position of the side holes on the workpiece 3, and the bottom hole detection rod 17 detects the holes at the bottom of the workpiece 3 to ensure that the bottom hole positions are processed in accordance with the standards. When the workpiece 3 is placed on the support plate 11, the bottom hole detection rod 17 detects the bottom holes, the lifting detection component 13 detects the higher bottom holes, and the side hole detection component 15 moves from the side towards the workpiece 3 to detect the side holes on the workpiece 3, ensuring that the holes in all directions can be accurately identified and avoiding missed detections. Two auxiliary handles 4 mounted on the support plate 11 are used to move the position of the detection bracket 1 so that the device is placed in the appropriate position.

[0033] The lifting detection assembly 13 includes a mounting post 131, a lifting plate 132 mounted on the mounting post 131, and multiple high-position detection rods 133 mounted on the lifting plate 132. The mounting post 131 provides an installation position for the lifting plate 132, and the lifting plate 132 is fixed to the mounting post 131 by a threaded connection. The multiple high-position detection rods 133 are adapted to the high-position holes of the workpiece 3 and are distributed on the surface of the lifting plate 132. The high-position detection rods 133 detect the high-position holes of the workpiece 3 to avoid missed detections or misjudgments.

[0034] The side hole detection assembly 15 includes multiple sliding devices 151 and limiting bolts 159. A synchronous moving connecting block 154 is slidably installed on the sliding device 151 located in the middle of the support plate 11. Connecting rods 155 are rotatably installed on both sides below the synchronous moving connecting block 154 through the limiting bolts 159. The other ends of the two connecting rods 155 are respectively rotatably installed with a first sliding plate 152 and a second sliding plate 156 through the limiting bolts 159. A side hole detection rod 153 is installed on both the first sliding plate 152 and the second sliding plate 156.

[0035] The sliding device 151 includes a slide rail and a slider. The slider can slide back and forth in the horizontal direction on the slide rail. The slide rail part of the sliding device 151 is mounted on the support plate 11 to provide stable guide support for the slider. The limiting bolt 159 is a limiting structure composed of a bolt, nut and washer, used to fix the rotational freedom at the hinge. The synchronous moving connecting block 154 provides the installation position. The synchronous moving connecting block 154 serves as a transmission connecting component. Its two sides are hinged to the first sliding plate 152 and the second sliding plate 156 respectively through two connecting rods 155. The side hole detection rod 153 is fixed on the first sliding plate 152 and the second sliding plate 156 to detect the hole positions on both sides of the workpiece 3 respectively.

[0036] Two sliding devices 151 are symmetrically installed below the first sliding plate 152 and the second sliding plate 156. Two limiting blocks 157 are also symmetrically arranged below the limiting bolt 159. The side hole detection assembly 15 also includes a sliding proximity sensor 158. The sliding proximity sensor 158 is located on the side of the second sliding plate 156 near the synchronous moving connecting block 154. The sliding proximity sensor 158 is fixed on the support plate 11. An auxiliary handle 4 is installed on the side of the first sliding plate 152 and on the top of the second sliding plate 156.

[0037] Both the first sliding plate 152 and the second sliding plate 156 are connected to the slider portion of the first sliding plate 152. When the first sliding plate 152 is driven to move horizontally on the slide rail of the sliding device 151 by the auxiliary handle 4 on the first sliding plate 152, the slider below the synchronous moving connecting block 154 slides synchronously on the slide rail of its corresponding sliding device 151, thereby driving the second sliding plate 156 to move synchronously along the slide rail, ensuring that the actions of the two detection mechanisms are consistent and improving detection accuracy. The limiting block 157 acts as a limiting stop to prevent the second sliding plate 156 from exceeding the preset stroke during movement, avoiding mechanical collisions that could damage the components. The sliding proximity sensor 158 is used to sense the moving position of the second sliding plate 156, providing real-time feedback of displacement data to ensure that the detection action is in place, and forming a closed-loop feedback with the electrical control box 2 to ensure that the second sliding plate 156 stops at the accurate position during each detection, improving the accuracy of repeated positioning. While limiting the second sliding plate 156, the stroke of the first sliding plate 152 is also limited, ensuring that the two detection components operate synchronously and avoiding detection errors due to displacement deviation.

[0038] See Figure 4 The processed part 3 includes a perforated body 31, a first abutting edge 33 and a second abutting edge 34. The perforated body 31 is provided with a bottom hole 32, a positioning hole 35 and a side hole 36.

[0039] The perforated body 31 is the main structural component, the bottom hole 32 and the side hole 36 are through holes that need to be formed on the perforated body 31, and the second abutting edge 34 and the first abutting edge 33 are the high and low sides.

[0040] The corner positioning rod 16 is adapted to the first abutment edge 33 and the second abutment edge 34.

[0041] The corner positioning rods 16 support the first abutment edge 33 and the second abutment edge 34. After the perforated body 31 is restricted to lateral movement by the positioning bolts 14, the corner positioning rods 16 simultaneously constrain the vertical displacement of the workpiece 3, ensuring that the perforated body 31 maintains a stable posture during the inspection process and preventing positional deviation caused by vibration or external force, thereby ensuring the accuracy of the inspection benchmark. The corner positioning rods 16 are rectangularly distributed on the support plate 11. A pair of shorter corner positioning rods 16 are located below the second abutment edge 34 to provide support, while another pair of taller corner positioning rods 16 are supported at the bottom of the first abutment edge 33. The stepped support structure adapts to the asymmetrical layout of the perforated body 31, so that the perforated body 31 is subjected to balanced force during inspection.

[0042] The position of the proximity sensor 18 is adapted to the height of the perforated body 31.

[0043] The positioning proximity sensor 18 detects the placement position of the perforated body 31. When the perforated body 31 is accurately in place, the positioning proximity sensor 18 sends a signal to confirm that the positioning is complete before the detection program can be started. This avoids data distortion or abnormal equipment operation caused by the workpiece not being placed in place. The positioning proximity sensor 18 is linked with the electrical control box 2.

[0044] By setting a support plate 11 to support the workpiece 3, a bottom hole detection rod 17 to detect the through hole at the bottom of the workpiece 3, a lifting detection component 13 to detect the high-level through hole at the bottom of the workpiece 3, a positioning bolt 14 to position the workpiece 3 laterally, and a side hole detection component 15 to simultaneously detect the holes on both sides of the workpiece 3, the workpiece 3 can be inspected from multiple directions and its positioning status. This improves the inspection efficiency and accuracy, ensures that each workpiece meets the design requirements before entering the next process, effectively reduces the false detection rate and the missed detection rate, and ensures the continuity of production and the stability of product quality.

[0045] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
