Description

[0001] This application is a divisional application. The application number of the original application is 2024109834869, the original application date is July 22, 2024, and the entire content of the original application is incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of suspension bracket detection, and particularly to a suspension bracket detection device with a positioning function. Background Art

[0003] Engine suspension brackets are widely used in various types of vehicles and are important components to ensure the stable operation of the engine, improve vehicle comfort and safety. Their performance and quality are directly related to vehicle comfort and safety. The suspension bracket can reduce the vibration generated during engine operation from being transmitted to the vehicle body, improving driving comfort and stability. The engine suspension bracket is connected to the engine housing and the vehicle frame through bolts. To ensure the accuracy of engine installation, it is necessary to precisely control the dimensions of the engine suspension bracket and the dimensional deviation of the positioning holes, and perform inspections on the size, hole pitch, burrs, etc. of the finished workpieces after production to prevent unqualified products from entering the market and avoid engine installation deviations caused by dimensional deviations of the suspension bracket. In the common inspection work of the size, hole pitch, and burrs of engine suspension brackets, generally, manual measurement with a measuring ruler or intelligent vision inspection instruments is used for inspection.

[0004] In the inspection work of engine suspension brackets, due to the cumbersome manual inspection operation, low inspection accuracy and efficiency, it has gradually been replaced by high-efficiency and high-precision intelligent vision inspection instruments. When using traditional intelligent vision inspection instruments, it is necessary to manually place the product on the inspection platform and position it directly below the visual inspection camera mechanism. For products such as engine suspension brackets with planes at different angles and openings on planes facing different directions, it is necessary to manually adjust it multiple times, which is cumbersome and cannot perform synchronous visual inspection of multiple surfaces of the suspension bracket through multiple cameras, and the inspection efficiency cannot be further improved. Summary of the Invention

[0005] The present invention relates to a suspension bracket detection device with a positioning function to solve the problem that when using traditional intelligent vision inspection instruments, it is necessary to manually place the product on the inspection platform and position it directly below the visual inspection camera mechanism. For products such as engine suspension brackets with planes at different angles and openings on planes facing different directions, it is necessary to manually adjust it multiple times, which is cumbersome and cannot perform synchronous visual inspection of multiple surfaces of the suspension bracket through multiple cameras, and the inspection efficiency cannot be further improved.

[0006] In the first aspect of the present disclosure, a suspension bracket detection device with a positioning function is provided, specifically including: a detection platform, on the outer surface of which three side struts are fixedly connected. At the upper ends of the side struts, an upper cover frame is installed. On the lower surface of the upper cover frame, three vision detection cameras are provided.

Four vertical guide rods are movably connected to the rotation conversion frame. All four vertical guide rods are perpendicular to the upper surface of the detection platform. On each of the four vertical guide rods, a workpiece detection carrier plate is rotatably connected. On the workpiece detection carrier plate, two positioning clamping plates are movably connected. At the inner ends of the workpiece detection carrier plates, two carrier plate orientation rollers are rotatably connected through bearings. At a position near the front edge of the upper surface of the detection platform, a discharge trigger plate is vertically installed by screws. On the upper surface of the detection platform, a directional rolling track is fixedly connected. The directional rolling track is a double-layer rail ring type track. The carrier plate orientation rollers are in rolling connection with the upper rail ring in the double-layer directional rolling track.

[0007] Further, on the right side of the front edge of the detection platform, there is a discharge port with a forward and downward inclined structure.

[0008] Further, the directional rolling track has a circular ring structure, is coaxial with the rotating shaft of the servo motor, and is provided with a first inclined raceway and a second inclined raceway which are bent on it.

[0009] Further, an iron coating is provided on the lower surface of the upper cover frame. At the top of the vision detection camera, a magnetic suction base is fixedly connected. The magnetic suction base is magnetically connected to the iron coating on the lower surface of the upper cover frame.

[0010] Further, four rotating linkages are fixedly connected to the outer surface of the rotation conversion frame. At the outer ends of the rotating linkages, guide sliders are fixedly connected. A lifting chute is longitudinally penetrated through the center of the guide slider. The axis of the lifting chute is perpendicular to the upper surface of the detection platform. Two convex strips are provided on the inner wall of the lifting chute. A balance tension spring is fixedly connected to the lower end surface of the lifting chute.

[0011] Further, the vertical guide rod is slidably connected to the lifting chute. Two chutes are opened on the outer wall of the vertical guide rod. The chutes are slidably connected to the convex strips inside the lifting chute. A guide rod convex ring is fixedly connected to the vertical guide rod. The vertical guide rod is movably inserted into the balance tension spring. The lower end of the balance tension spring is fixedly connected to the upper surface of the guide rod convex ring. At the lower end of the vertical guide rod, a ninety-degree bent rod is provided outward. The bent rod part of the vertical guide rod is rotatably connected to the inner end surface of the workpiece detection carrier plate through a bearing.

[0012] Furthermore, four rectangular movable sliding holes are perforated through the workpiece detection carrier plate. The lower surface of the workpiece detection carrier plate is fixedly connected to a carrier plate guide rail by screws, and a tension spring connecting plate is vertically connected to the lower surface of the carrier plate guide rail.

[0013] Furthermore, an arc-shaped lower pushing arc plate is fixedly connected to the lower surface of the positioning clamping plate. A clamping plate tension spring is fixedly connected to the inner surface of the lower pushing arc plate, and the inner end of the clamping plate tension spring is fixedly connected to the tension spring connecting plate. A clamping plate sliding groove is formed on the upper surface of the positioning clamping plate, and the clamping plate sliding groove is slidably connected to the carrier plate guide rail.

[0014] Furthermore, two round rod-shaped clamping columns are vertically arranged on the upper surface of the positioning clamping plate. The clamping columns are slidably connected to the movable sliding holes, and the upper ends of the clamping columns are processed with column end wedge surfaces, and the column end wedge surfaces face the center direction of the workpiece detection carrier plate.

[0015] Furthermore, two spacing limiting rollers are rotatably connected above the unloading trigger plate through bearings. The axes of the spacing limiting rollers are perpendicular to the upper surface of the detection platform, and the spacing limiting rollers are in rolling connection with the lower pushing arc plate moving to this position.

[0016] The present invention provides a suspension bracket detection device with a positioning function, having the following beneficial effects: The detection device for the suspension bracket in the present invention is an intelligent vision detection device with automatic angle adjustment. Through the cooperation of the vision detection camera and the vision detection calculation panel, the quality detection of the appearance dimensions, burrs, surface scratches, hole sizes, hole positions, etc. of the suspension bracket can be effectively detected. It has a wide range of applications and does not require manual use of a measuring ruler for measurement. Compared with manual detection, the detection accuracy and detection efficiency are improved.

[0017] In addition, a quick positioning structure with a suspension bracket is provided. When fixing the suspension bracket, place the bracket base downward, align the four bolt holes with the four clamping columns respectively, and insert the bolt holes onto the clamping columns. The wedge surface at the end of the column contacts the bolt hole of the suspension bracket. As a downward thrust is applied to the suspension bracket, the suspension bracket comes into close contact with the wedge surface at the column end and pushes the clamping column outward. After the suspension bracket contacts the upper surface of the workpiece detection carrier plate, the clamping column moves closer to the middle under the pulling force of the clamping plate spring, so that the clamping column comes into close contact with the inner wall of the spiral hole, firmly clamping the suspension bracket. The installation method of the suspension bracket is quick. When the detection of the suspension bracket is completed, as the servo motor drives it to rotate clockwise to the front edge of the detection platform, the two downward extrusion arc plates at the bottom of the suspension bracket contact and form a rolling connection with the spacing limiting roller. Due to the action of the inclined surface of the downward extrusion arc plate, when the downward extrusion arc plate passes through the spacing limiting roller, the spacing limiting roller pushes the downward extrusion arc plate in a direction away from the center of the workpiece detection carrier plate, separating the four clamping columns from the inner wall of the bolt hole of the suspension bracket, causing the suspension bracket to tilt to the right and roll down to the discharge port under its own gravity, having the function of automatic unloading.

[0018] In addition, three vision detection cameras are built into the detection device, which respectively detect the three suspension brackets at the bottom of the upper cover frame from three different positions. The servo motor and the rotation conversion frame drive the workpiece detection carrier plate and the suspension bracket to rotate clockwise. During this process, through the cooperation of the carrier plate orientation roller and the orientation rolling track, the workpiece detection carrier plates at different positions are at different inclination angles, changing the orientation of the suspension brackets at different positions, so that different inclined surfaces of the suspension brackets face the vision detection camera respectively when passing through different detection positions. The vision detection camera visually detects the surfaces with different orientations in the suspension bracket, enabling the suspension bracket to complete the detection of multiple surfaces with different orientations during the process of being driven by the workpiece detection carrier plate to rotate one week, without manual manual commutation or adjustment of the suspension bracket, making the angle adjustment of the suspension bracket more efficient and smooth.

Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0024] Embodiment 1: Please refer to Figures 1 to 15 : The present invention provides a suspension bracket detection device with a positioning function, including: a detection platform 1, on the outer surface of which three side struts 102 are fixedly connected. At the upper ends of the side struts 102, an upper cover frame 2 is installed. On the lower surface of the upper cover frame 2, three vision detection cameras 3 are provided. On the upper surface of the upper cover frame 2, a vision detection calculation panel 4 is fixedly connected. The vision detection calculation panel 4 is connected to the three vision detection cameras 3 through electrical connection lines. At the center of the upper surface of the detection platform 1, a servo motor 5 is fixedly connected by bolts. The rotating shaft of the servo motor 5 is perpendicular to the upper surface of the detection platform 1. On the rotating shaft of the servo motor 5, a rotation conversion frame 6 is fixedly connected. On the rotation conversion frame 6, four vertical guide rods 7 are movably connected. The four vertical guide rods 7 are all perpendicular to the upper surface of the detection platform 1. On each of the four vertical guide rods 7, a workpiece detection carrier plate 8 is rotatably connected. On the workpiece detection carrier plate 8, two positioning clamping plates 9 are movably connected. At the inner ends of the workpiece detection carrier plates 8, two carrier plate orientation rollers 801 are rotatably connected by bearings. At a position near the front edge of the upper surface of the detection platform 1, a discharge trigger plate 10 is vertically installed by screws. On the upper surface of the detection platform 1, a directional rolling track 103 is fixedly connected. The directional rolling track 103 is a double-layer rail ring type track. The carrier plate orientation rollers 801 are in rolling connection with the upper rail ring in the double-layer directional rolling track 103. The directional rolling track 103 has an annular structure and is coaxial with the rotating shaft of the servo motor 5. On the directional rolling track 103, a first inclined track 104 and a second inclined track 105 are bent. The slopes of the first inclined track 104 and the second inclined track 105 can be customized according to the structure of the suspension bracket to be detected. On the lower surface of the upper cover frame 2, an iron coating is provided. At the top of the vision detection camera 3, a magnetic suction base 301 is fixedly connected. The magnetic suction base 301 is magnetically connected to the iron coating on the lower surface of the upper cover frame 2, which is convenient for adjusting the position of the vision detection camera 3 according to the actual situation. The vision detection camera 3 vertically photographs the suspension bracket located directly below it and transmits the image to the vision detection calculation panel 4 for calculation and analysis to detect whether there are burrs or defects on the surface and whether there are deviations in the opening size and position. The vision detection calculation panel 4 can display the picture and the detection data, which is conducive to quality inspection personnel for processing.

[0025] In the embodiment of the present disclosure, four rotating link rods 601 are fixedly connected to the outer surface of the rotation reversing frame 6. The outer end of the rotating link rod 601 is fixedly connected to a guiding slider 602. A lifting chute 603 is longitudinally penetrated through the center of the guiding slider 602. The axis of the lifting chute 603 is perpendicular to the upper surface of the detection platform 1. Two convex strips are provided on the inner wall of the lifting chute 603. A balance tension spring 604 is fixedly connected to the lower end surface of the lifting chute 603; the vertical guide rod 7 is slidably connected to the lifting chute 603. Two chutes are opened on the outer wall of the vertical guide rod 7. The chutes are slidably connected to the inner convex strips of the lifting chute 603. A guide rod convex ring 701 is fixedly connected to the vertical guide rod 7. The vertical guide rod 7 is movably inserted into the balance tension spring 604. The lower end of the balance tension spring 604 is fixedly connected to the upper surface of the guide rod convex ring 701. The lower end of the vertical guide rod 7 is provided with a ninety-degree bent rod outward. The bent rod portion of the vertical guide rod 7 is rotatably connected to the inner end surface of the workpiece detection carrier plate 8 through a bearing; the vertical guide rod 7 is slidably connected to the lifting chute 603, which plays a guiding role to maintain the verticality of the vertical guide rod 7. Through the action of the balance tension spring 604, the vertical guide rod 7 is pulled upward to keep the carrier plate directional roller 801 always in rolling connection with the directional rolling track 103.

[0026] In the embodiment of the present disclosure, four rectangular structure movable sliding holes 802 are penetrated through the workpiece detection carrier plate 8. The lower surface of the workpiece detection carrier plate 8 is fixedly connected to a carrier plate guide rail 803 through screws. A tension spring connecting plate 804 is vertically connected to the lower surface of the carrier plate guide rail 803; with the action of the rotation reversing frame 6, the workpiece detection carrier plate 8 is driven to rotate around the axis of the servo motor 5, and the carrier plate directional roller 801 rolls along the directional rolling track 103. When the carrier plate directional roller 801 rolls to the position of the first inclined track 104 or the second inclined track 105, the workpiece detection carrier plate 8 follows the inclination, and the center height of the workpiece detection carrier plate 8 is lowered, so that the vertical guide rod 7 slides downward from the inside of the guiding slider 602. In this state, as the workpiece detection carrier plate 8 inclines, the suspension bracket above the workpiece detection carrier plate 8 inclines, so that one side of the suspension bracket faces directly upward. The visual detection camera 3 takes a picture of the upper surface of the suspension bracket directly above and analyzes and calculates the image through the visual detection calculation panel 4 to perform quality detection on the shape size, burr, surface scratch, hole size, hole position, etc. of the surface. It can be seen that as the position of the suspension bracket changes, its angle changes accordingly, so as to better adjust the surfaces of different orientations of the suspension bracket to face directly the visual detection camera 3, improve the imaging accuracy of the visual detection camera 3, and realize the detection of the suspension bracket in different directions respectively.

[0027] In an embodiment of the present disclosure, a downward-pushing arc plate 901 with an arc structure is fixedly connected to the lower surface of the positioning clamping plate 9. A clamping plate spring 902 is fixedly connected to the inner surface of the downward-pushing arc plate 901. The inner end of the clamping plate spring 902 is fixedly connected to a spring connecting plate 804. A clamping plate sliding groove 903 is formed in the upper surface of the positioning clamping plate 9, and the clamping plate sliding groove 903 is slidably connected to a carrier guide rail 803. Two clamping columns 904 with a round rod structure are vertically arranged on the upper surface of the positioning clamping plate 9. The clamping columns 904 are slidably connected to movable sliding holes 802. The upper end of the clamping column 904 is processed with a column end wedge surface 905, and the column end wedge surface 905 faces the center direction of the workpiece detection carrier plate 8. When installing the suspension bracket, the bracket base is facing downwards, and the four bolt holes respectively correspond to the four clamping columns 904, and the bolt holes are sleeved on the clamping columns 904. The column end wedge surface 905 contacts the bolt holes of the suspension bracket. As a downward thrust is applied to the suspension bracket, the suspension bracket is in close contact with the column end wedge surface 905 and pushes the clamping column 904 outwards. After the suspension bracket contacts the upper surface of the workpiece detection carrier plate 8, the clamping column 904 moves towards the middle under the pulling force of the clamping plate spring 902, so that the clamping column 904 is in close contact with the inner wall of the screw hole, firmly clamping the suspension bracket and realizing the quick installation of the suspension bracket.

[0028] Embodiment 2: On the basis of Embodiment 1, a discharge port 101 with a structure inclined forward and downward is arranged on the right side of the front edge of the detection platform 1. Two spacing-limiting rollers 1001 are rotatably connected above the discharge trigger plate 10 through bearings. The axis of the spacing-limiting rollers 1001 is perpendicular to the upper surface of the detection platform 1, and the spacing-limiting rollers 1001 are in rolling connection with the downward-pushing arc plates 901 moving to this position. When the detection of the suspension bracket is completed and the servo motor 5 drives the suspension bracket to rotate clockwise to the front edge of the detection platform 1, the two downward-pushing arc plates 901 at the bottom of the suspension bracket contact the spacing-limiting rollers 1001 and form a rolling connection. Due to the action of the inclined surface of the downward-pushing arc plate 901, when the downward-pushing arc plate 901 passes through the spacing-limiting rollers 1001, the downward-pushing arc plate 901 is pushed away from the center of the workpiece detection carrier plate 8 through the spacing-limiting rollers 1001, so that the four clamping columns 904 are separated from the inner wall of the bolt holes of the suspension bracket, and the suspension bracket tilts to the right and rolls down to the discharge port 101 under its own gravity, realizing the automatic discharge of the suspension bracket.

[0029] The working principle of this embodiment: First, start the servo motor 5 to make the servo motor 5 rotate intermittently clockwise, with a single rotation angle of 90 degrees, and stay still for 1 to 3 seconds after each single rotation. When performing the detection work of the suspension bracket, when the servo motor 5 is stationary, the suspension bracket is attached with Figure 1It is installed above the workpiece detection carrier plate 8 at an angle and applies a vertical downward thrust to the suspension bracket, causing the suspension bracket to closely contact the column end wedge surface 905 and push the clamping column 904 outward. After the suspension bracket contacts the upper surface of the workpiece detection carrier plate 8, the clamping column 904 moves closer to the middle under the pulling force of the clamping plate tension spring 902, causing the clamping column 904 to closely contact the inner wall of the spiral hole and firmly clamp the suspension bracket. Then, with the start of the servo motor 5, it drives the rotation conversion frame 6 to rotate clockwise, causing the front suspension bracket to rotate to the left and enter directly below the left vision detection camera 3. The vision detection camera 3 takes a picture of the upward-facing side of the suspension bracket and transmits it to the vision detection calculation panel 4 for image analysis to detect its size, shape, and whether there are burrs. At the same time, the staff installs the suspension bracket to be detected on the workpiece detection carrier plate 8 directly in front. With the restart of the servo motor 5, the suspension bracket enters the first inclined track 104. Due to the slope of the first inclined track 104 and the pulling effect of the balance tension spring 604 on the vertical guide rod 7, the workpiece detection carrier plate 8 tilts, causing the suspension bracket to follow the tilt and adjust the other side of the suspension bracket to a horizontal setting, facilitating the vision detection camera 3 above the suspension bracket to take a picture of it. Similarly, with the continuous operation of the servo motor 5 and in cooperation with the second inclined track 105, the suspension bracket is adjusted at an angle again, causing the suspension bracket to rotate to the three detection areas and be adjusted to three different angles simultaneously. The three vision detection cameras 3 respectively take pictures of the three surfaces of the suspension bracket and transmit them to the vision detection calculation panel 4 for intelligent analysis and calculation to achieve the detection of the size, shape, hole opening position, hole opening size, and burrs of the suspension bracket. The vision detection calculation panel 4 displays the detection pictures and data to assist the operator in quality inspection work; when the detected suspension bracket moves forward from the right with the rotation of the servo motor 5, the two downward pushing arc plates 901 at the bottom of the suspension bracket contact and form a rolling connection with the spacing limiting roller 1001. Due to the effect of the inclined surface of the downward pushing arc plate 901, when the downward pushing arc plate 901 passes through the spacing limiting roller 1001, the spacing limiting roller 1001 pushes the downward pushing arc plate 901 in a direction away from the center of the workpiece detection carrier plate 8, causing the four clamping columns 904 to separate from the inner wall of the suspension bracket bolt hole, and the suspension bracket tilts to the right and rolls down to the discharge port 101 under its own gravity, realizing the automatic unloading of the suspension bracket.
