Detailed Implementation

[0023] 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.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A dual-station inspection mechanism for machine tool processing includes a base 1. A non-contact inspection component 4 is disposed on the top of the base 1, and auxiliary inspection components 5 are disposed on both sides of the non-contact inspection component 4. The non-contact inspection component 4 includes a support rod 401 fixedly connected to the top of the base 1, a top plate 402 fixedly connected to the top of the support rod 401, a drive cylinder 403 fixedly connected to the top of the top plate 402, a support base 404 fixedly connected to the output end of the drive cylinder 403, a limiting slide 405 fixedly connected to the outer side of the support base 404, the limiting slide 405 being slidably connected to the support rod 401, a vision inspection support 406 fixedly connected to the front side of the support base 404, and an industrial camera 407 disposed at the bottom of the vision inspection support 406.

[0026] In this embodiment: the drive cylinder 403 is activated, and its output end pushes the support base 404 to move vertically. The limiting slide 405 on the outside of the support base 404 slides with the support rod 401, which plays a guiding role when the support base 404 moves, preventing the support base 404 from deviating and ensuring that the support base 404 drives the related components to rise and fall smoothly. As the support base 404 moves, the vision inspection support 406 on its front side adjusts its position synchronously. The industrial camera 407 at the bottom of the support then reaches the shooting height and angle adapted to the workpiece. At this time, the industrial camera 407 acquires images of the workpiece on the drive moving mechanism 2. The acquired images are transmitted to the image processor 3 on the top of the vision inspection support 406 through an electrical connection. After analysis and processing, the image processor 3 completes the non-contact inspection of the appearance and size of the workpiece. The whole process realizes flexible adjustment of the detection position and rapid output of the detection results through the cooperation between the components.

[0027] Specifically, such as Figure 3 As shown, the auxiliary detection component 5 includes a support plate 501 fixedly connected to the outside of the support base 404. Reinforcing plates 502 are fixedly connected to both sides of the support plate 501. The reinforcing plates 502 are fixedly connected to the support base 404. A lifting cylinder 503 is fixedly connected to the top of the support plate 501.

[0028] Specifically, such as Figure 3As shown, a connecting plate 504 is fixedly connected to the output end of the lifting cylinder 503, and a tilting cylinder 505 is fixedly connected to the bottom of the connecting plate 504.

[0029] Specifically, such as Figure 3 As shown, a detection seat 506 is fixedly connected to the output end of the tilting cylinder 505, and a detection head 507 is provided on the top of the detection seat 506.

[0030] In this embodiment: after the workpiece is moved to the secondary inspection position by the driven gripper 10, the support plate 501 on the outside of the support base 404 provides an installation base for the auxiliary inspection-related components. The reinforcing plates 502 on both sides of the support plate 501 are connected to the support plate 501 at one end and fixed to the support base 404 at the other end, enhancing the connection strength between the support plate 501 and the support base 404 and preventing the components from loosening due to vibration during inspection. At this time, the lifting cylinder 503 at the top of the support plate 501 is activated, and its output end pushes the connecting plate 504 downward. The bottom tilting cylinder 505 is driven to adjust the height synchronously, so that the detection head 507 is close to the part of the workpiece to be inspected. When the height is adjusted to the right position, the tilting cylinder 505 is activated, and its output end drives the detection seat 506 to rotate. The detection head 507 on the top of the detection seat 506 is tilted synchronously with the detection seat 506 and adjusted to an angle that matches the surface of the workpiece to be inspected. Finally, the detection head 507 contacts the workpiece and performs contact inspection on the workpiece's shape and position errors, local dimensions, etc. Through flexible adjustment of height and angle, comprehensive inspection of complex parts of the workpiece can be achieved.

[0031] Specifically, such as Figure 4 , Figure 5 As shown, a fixed plate 6 is fixedly connected to the bottom of the support base 404, a drive motor 7 is fixedly connected to the outside of the fixed plate 6, a drive screw 8 is fixedly connected to the output end of the drive motor 7, a movable seat 9 is threadedly connected to the outside of the drive screw 8, and a drive gripper 10 is fixedly connected to the bottom of the movable seat 9.

[0032] Specifically, such as Figure 5 As shown, a limiting slider 11 is fixedly connected to the bottom of the fixed plate 6, and the side of the limiting slider 11 away from the fixed plate 6 is slidably connected to the movable seat 9.

[0033] In this embodiment: by setting up a fixed plate 6, a drive motor 7, a drive screw 8, a moving seat 9, and a drive gripper 10, when the non-contact inspection is completed and the workpiece needs to be gripped for subsequent auxiliary inspection, the fixed plate 6 fixed at the bottom of the support base 404 provides a stable mounting base for components such as the drive motor 7 and the drive screw 8. At this time, the drive motor 7 on the outside of the fixed plate 6 starts, and its output end drives the drive screw 8 to start rotating. Since the drive screw 8 is threadedly connected to the moving seat 9, the rotating drive screw 8 will cause the moving seat 9 to move, and the drive gripper 10 fixed at the bottom of the moving seat 9 moves synchronously with the moving seat 9. Until it reaches above the workpiece, the drive gripper 10 is then activated to precisely clamp the workpiece so that it can be transferred to the secondary inspection position. By setting a limit slider 11, as the moving seat 9 moves with the drive screw 8, the limit slider 11 fixed at the bottom of the fixed plate 6 maintains a sliding connection with the moving seat 9. The limit slider 11 can provide guidance for the movement of the moving seat 9, restricting the moving seat 9 to move only along the extension direction of the limit slider 11, avoiding the moving seat 9 from shifting or shaking due to the rotation of the drive screw 8, ensuring that the moving seat 9 drives the drive gripper 10 to move smoothly and accurately above the workpiece, and ensuring the accuracy of the gripping position.

[0034] Specifically, such as Figure 1 As shown, a drive mechanism 2 is provided on the top of the base 1, and the drive mechanism 2 is located at the bottom of the support base 404.

[0035] Specifically, such as Figure 1 As shown, an image processor 3 is provided on the top of the vision inspection support 406, and the image processor 3 is electrically connected to the industrial camera 407.

[0036] In this embodiment: By setting up a driving moving mechanism 2, the driving moving mechanism 2 is activated before the start of the entire inspection process. It can carry the workpieces produced by the dual-station production and transport the workpieces smoothly to the preset inspection area. Through stable conveying action, it provides a fixed workpiece inspection position for subsequent non-contact inspection and auxiliary inspection, avoiding positional deviations caused by manual placement of workpieces, ensuring a smooth and efficient inspection process, and adapting to the batch inspection needs of dual-station production, thereby improving inspection efficiency. By setting up an image processor 3, when the industrial camera 407 in the non-contact inspection component 4 acquires images of the workpiece, the image processor 3 on the top of the vision inspection support 406 receives the image signal transmitted by the industrial camera 407 through an electrical connection. The image processor 3 quickly analyzes the received image, identifies the size parameters of the workpiece, whether there are scratches or dents on the surface, and uses the analysis results as a preliminary inspection basis to achieve real-time output of inspection results, avoiding the lag and error of manual judgment, and improving the accuracy and efficiency of non-contact inspection.

[0037] Working Principle: In the process of using this dual-station inspection mechanism for machine tool processing, the workpieces produced at both stations are first transported to the inspection area by the drive moving mechanism 2, providing stable workpiece transport support for subsequent inspection work. When the workpiece reaches the designated inspection position, the non-contact inspection component 4 initiates the inspection process. Its support rod 401 provides stable support for the entire component, while the top 402 fixed to the top of the support rod 401 provides the mounting base for the drive cylinder 403. Then, the drive cylinder 403 starts working, and its output end pushes the support seat 404 fixed to it to move up and down. The limiting slide 405 fixed to the outside of the support seat 404 is slidably connected to the support rod 401, so that the support seat 404 is driven by the drive cylinder 403. The lower part can slide smoothly along the axial direction of the support rod 401, effectively avoiding deviation or shaking during the lifting and lowering of the support base 404, ensuring the accuracy of the detection position. As the position of the support base 404 is adjusted, the vision inspection support 406 fixed to the front side of the support base 404 also moves accordingly. Then, the industrial camera 407 set at the bottom of the vision inspection support 406 reaches the appropriate shooting height and angle. At this time, the industrial camera 407 acquires images of the workpiece on the drive moving mechanism 2 below. At the same time, the image processor 3 set at the top of the vision inspection support 406 is electrically connected to the industrial camera 407. The industrial camera 407 transmits the acquired workpiece image to the image processor 3 in real time. The image processor 3 analyzes and processes the image for rapid identification. The workpiece's dimensions, surface condition, and other appearance information are analyzed using non-contact inspection to preliminarily assess its processing quality. After non-contact inspection, the workpiece needs to be gripped for subsequent contact inspection by auxiliary inspection component 5. At this point, drive motor 7 starts, and its output drives drive screw 8, which is fixedly connected to it, to rotate. Since a movable seat 9 is threaded onto the outer side of drive screw 8, and the limiting slider 11 fixed at the bottom of fixed plate 6 is slidably connected to the movable seat 9, the rotational motion of drive screw 8 is converted into linear motion of movable seat 9 under the guidance of limiting slider 11. Movable seat 9 slides smoothly along limiting slider 11, thereby driving the drive gripper 10 fixed at its bottom to move synchronously until the drive gripper 10 moves directly above the workpiece. The drive gripper 10 actuates, precisely clamping the workpiece. At this time, the drive motor 7 starts running again, driving the drive gripper 10 and the clamped workpiece to the preset secondary inspection position through the cooperation of the drive screw 8 and the moving seat 9, preparing for the operation of the auxiliary inspection component 5. After the workpiece is stably clamped by the drive gripper 10 and moved to the designated position, the lifting cylinder 503 of its support plate 501 is activated. Then, its output end pushes the connecting plate 504 fixedly connected to it to move downward. Then, the movement of the connecting plate 504 drives the bottom fixed tilting cylinder 505 to move synchronously, thereby adjusting the height position of the tilting cylinder 505 and subsequent components, so that the inspection head 507 can approach the part of the workpiece to be inspected. When the height is adjusted to the correct position, the tilting cylinder 505 begins to work.Its output end drives the fixedly connected detection seat 506 to rotate. The rotation of the detection seat 506 then causes the detection head 507 on its top to rotate synchronously, adjusting the detection angle of the detection head 507 to ensure full contact between the detection head 507 and the surface to be inspected on the workpiece. Finally, after the detection head 507 contacts the workpiece, it accurately detects parameters such as the workpiece's form and position errors and local dimensional accuracy, completing the secondary contact inspection. Through the combination of non-contact and contact inspection, the accuracy and comprehensiveness of the inspection of workpieces processed in dual stations are fully guaranteed. Throughout the process, the precise connection and cooperation of each component achieves a seamless operation from workpiece transportation, preliminary inspection, workpiece gripping to secondary inspection, meeting the requirements for efficient and accurate inspection.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
