Description

Technical Field

[0001] This utility model relates to the field of deep hole detection technology, and in particular to a sealing ring detection device for ultra-deep holes. Background Technology

[0002] The upper suspension pump housing is a key component of the air suspension system, primarily used to house the air pump and form the air passage. Its sealing performance directly affects the reliability of the suspension system. The upper suspension pump housing has deep holes to accommodate the gear shaft, and O-rings are installed within these holes to isolate hydraulic oil from the air. Proper assembly of the O-rings is crucial to ensuring the sealing performance of the upper suspension pump housing.

[0003] In existing technologies, the assembly and inspection of O-rings inside the suspension pump housing of automobiles mainly relies on manual operation. During inspection, operators need to visually determine whether the O-rings are installed correctly. However, manual inspection is easily limited by lighting and viewing angle, making it difficult to identify 100% of the O-rings, resulting in poor reliability and causing defective products such as missing or misaligned O-rings to enter subsequent processes. In addition, manual inspection is inefficient and requires significant manpower. Utility Model Content

[0004] Therefore, it is necessary to provide a sealing ring testing device for ultra-deep holes to address the problems of missed or false detections, poor detection reliability, low detection efficiency, and high labor costs associated with existing manual inspection methods.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A sealing ring inspection device for ultra-deep holes includes a column, a linear drive component fixed to the side wall of the column, the output end of the linear drive component being connected to a vision inspection component via a lifting seat mechanism, and a positioning seat mechanism arranged on one side of the column, the working end of the positioning seat mechanism being connected to a workpiece.

[0007] The linear drive unit drives the vision inspection component to move in a straight line in the vertical direction through the lifting seat mechanism, thereby moving the vision inspection component to the inside of the workpiece. The positioning seat mechanism drives the workpiece to rotate, thereby taking a picture of the inside of the workpiece through the vision inspection component, and then determining whether the sealing ring inside the workpiece is installed in place.

[0008] As a further improvement to the above technical solution:

[0009] The visual inspection component includes a camera and an optical rigid lens located below the camera.

[0010] The lifting seat mechanism has the following structure: it includes a connecting plate connected to the output end of the linear drive component, and a mounting seat is fixed on the end face of the connecting plate. The mounting seat is used to fix the camera and the optical rigid lens.

[0011] A limiting seat is also fixed on the end face of the connecting plate. A through hole is provided on the end face of the limiting seat. A sleeve is installed in the through hole, and the lens tube of the optical rigid lens is inserted into the sleeve.

[0012] The sleeve is installed on the limiting seat by clamps.

[0013] The mounting base is T-shaped, with the camera fixed on the vertical end face of the mounting base and the optical rigid lens fixed on the horizontal end face of the mounting base, so that the camera and the optical rigid lens are fixed on the mounting base from top to bottom at intervals.

[0014] The positioning base mechanism has the following structure: it includes a support base, a speed reducer is installed on the top of the support base, the input end of the speed reducer is connected to the output end of the servo motor, the output end of the speed reducer is connected to the positioning plate, and the top of the positioning plate is provided with a first positioning pin and a second positioning pin, which are used to fix and limit the workpiece.

[0015] The speed reducer uses a hollow shaft rotating platform.

[0016] The bottom of the workpiece is provided with a first positioning hole and a second positioning hole;

[0017] The first positioning hole corresponds to the first positioning pin, and the second positioning hole corresponds to the second positioning pin. By inserting the first positioning pin into the first positioning hole and simultaneously inserting the second positioning pin into the second positioning hole, the workpiece is fixed and limited.

[0018] The linear drive unit uses a servo module.

[0019] The bottom of both the column and the positioning seat mechanism is equipped with a base plate.

[0020] The beneficial effects of this utility model are as follows:

[0021] This utility model has a compact and reasonable structure and is easy to operate. By setting up a linear drive component, a lifting seat mechanism, a vision inspection component and a positioning seat mechanism, it can perform efficient and fully automatic inspection of the assembly status of the internal sealing ring of the workpiece. The inspection reliability is high, which can avoid missed inspections and false inspections, effectively improve inspection efficiency and reduce labor costs.

[0022] This utility model also has the following advantages:

[0023] (1) In this utility model, a camera is set up; an optical rigid lens is set up.

[0024] (2) By setting a sleeve tube, the tube of the optical rigid lens can be protected and limited, thereby improving the safety of the device during use.

[0025] (3) By setting a clamp, the device is easy to disassemble and assemble, and is convenient for later maintenance and replacement of optical hard tube lenses, which can improve the installation efficiency of the device.

[0026] (4) In this utility model, by setting a first positioning pin and a second positioning pin, as well as a first positioning hole and a second positioning hole corresponding to them, the workpiece is fixed and limited; at the same time, when the positioning plate rotates, the workpiece can rotate with the positioning plate.

[0027] (5) By setting a base plate, the straight distance between the column and the positioning seat mechanism can be fixed, thereby ensuring that the relative position of the vision inspection component and the workpiece in the horizontal direction remains stable. Attached Figure Description

[0039] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0040] The structure and function of this utility model are as follows:

[0041] like Figures 1-5 As shown, a sealing ring inspection device for ultra-deep holes includes a column 1, with a linear drive 2 fixed to the side wall of the column 1. The output end of the linear drive 2 is connected to a vision inspection component via a lifting mechanism 3. A positioning mechanism 5 is arranged on one side of the column 1, with its working end connected to a workpiece 8. The linear drive 2 drives the vision inspection component to move vertically in a linear motion via the lifting mechanism 3, thereby moving the vision inspection component to the interior of the workpiece 8. The positioning mechanism 5 then rotates the workpiece 8, allowing the vision inspection component to capture an image of the interior of the workpiece 8, thus determining whether the sealing ring inside the workpiece 8 is properly installed. By setting up the linear drive 2, lifting mechanism 3, vision inspection component, and positioning mechanism 5, the assembly status of the sealing ring inside the workpiece 8 can be efficiently and automatically inspected. The inspection reliability is high, avoiding missed or false inspections, effectively improving inspection efficiency and reducing labor costs.

[0042] like Figures 6-7 As shown, the workpiece 8 of this utility model has a deep hole 11 in the middle. A cylindrical boss 12 is concentrically arranged in the deep hole 11. An annular detection space is formed between the outer circular surface of the boss 12 and the inner circular surface of the deep hole 11. At least one mounting groove arranged along the circumference is opened on the outer circular surface of the boss 12. A sealing ring is installed in a single mounting groove.

[0043] The visual inspection assembly includes a camera 6 and an optical rigid lens 7 located below the camera 6. The camera 6 is used to detect the position of the deep hole 11, and the optical rigid lens 7 can extend into the inspection space to inspect the assembly status of the sealing ring therein.

[0044] like Figures 3-4 As shown, the lifting platform mechanism 3 has the following structure: it includes a connecting plate 301 connected to the output end of the linear drive 2; a mounting base 302 is fixed on the end face of the connecting plate 301, which is used to fix the camera 6 and the optical rigid lens 7; a limiting seat 303 is also fixed on the end face of the connecting plate 301, and a through hole is formed on the end face of the limiting seat 303. A sleeve tube 304 is installed in the through hole, and the lens tube of the optical rigid lens 7 is inserted into the sleeve tube 304. By setting the sleeve tube 304, the lens tube of the optical rigid lens 7 can be protected and limited, improving the safety of the device during use.

[0045] The sleeve 304 is mounted on the limiting seat 303 by a clamp 305. Specifically, the clamp 305 is clamped on the outer circumferential surface of the sleeve 304, and the clamp 305 is fixed to the limiting seat 303 by bolts, thereby fixing the sleeve 304 to the limiting seat 303; by setting the clamp 305, it is easy to disassemble and assemble, which can improve the installation efficiency of the device.

[0046] The mounting base 302 is T-shaped. The camera 6 is fixed to the vertical end face of the mounting base 302, and the rigid optical lens 7 is fixed to the horizontal end face of the mounting base 302, so that the camera 6 and the rigid optical lens 7 are fixed to the mounting base 302 from top to bottom. By setting the mounting base 302, a stable connection between the vision inspection component and the connecting plate 301 can be achieved, so that the linear drive 2 can drive the vision inspection component to move up and down in the vertical direction through the connecting plate 301.

[0047] like Figure 5 As shown, the positioning base mechanism 5 has the following structure: it includes a support base 501, a reducer 502 is mounted on the top of the support base 501, the input end of the reducer 502 is connected to the output end of the servo motor 503, and the output end of the reducer 502 is connected to the positioning plate 504. The top of the positioning plate 504 is provided with a first positioning pin 505 and a second positioning pin 506, which are used to fix and limit the workpiece 8. The servo motor 503 drives the positioning plate 504 to rotate through the reducer 502. Under the action of the first positioning pin 505 and the second positioning pin 506, the positioning plate 504 drives the workpiece 8 to rotate, so that the optical hard lens 7 extending into the detection space can take pictures of the outer circular surface of the boss 12, and then determine whether the sealing ring is assembled in place based on the pictures.

[0048] The reducer 502 adopts a hollow shaft rotary platform, which has high positioning accuracy and high rotation accuracy, and can be used in conjunction with vision inspection components for high-precision inspection.

[0049] The bottom of workpiece 8 has a first positioning hole 9 and a second positioning hole 10. The first positioning hole 9 corresponds to the first positioning pin 505, and the second positioning hole 10 corresponds to the second positioning pin 506. By inserting the first positioning pin 505 into the first positioning hole 9 and simultaneously inserting the second positioning pin 506 into the second positioning hole 10, the workpiece 8 is fixedly positioned. By setting the first positioning hole 9 and the second positioning hole 10, the workpiece 8 can be fixedly positioned by the first positioning pin 505 and the second positioning pin 506. In addition, when the positioning plate 504 rotates, the workpiece 8 can rotate with the positioning plate 504.

[0050] The linear drive component 2 adopts a servo module, which has precise positioning and controllable speed, and can efficiently drive the vision inspection component to improve the quality and efficiency of sealing ring inspection.

[0051] A base plate 4 is installed at the bottom of both the column 1 and the positioning seat mechanism 5. Both the column 1 and the positioning seat mechanism 5 are fixed on the base plate 4. By setting the base plate 4, the straight-line distance between the column 1 and the positioning seat mechanism 5 can be fixed, thereby ensuring that the relative position of the vision inspection component and the workpiece 8 in the horizontal direction remains stable.

[0052] The working process of this utility model is as follows:

[0053] like Figure 8 As shown, the workpiece 8 is placed on top of the positioning plate 504, and the first positioning pin 505 is inserted into the first positioning hole 9 and the second positioning pin 506 is inserted into the second positioning hole 10.

[0054] The vision inspection component communicates with the industrial control computer. When the vision inspection component is started, the camera 6 takes pictures at a certain frequency according to the set interval. At the same time, the linear drive 2 is started, which drives the vision inspection component to make a downward linear motion in the vertical direction.

[0055] During the descent of the vision inspection component, the industrial control computer determines the descent stroke of the vision inspection component based on the photo data captured by the camera 6. After the vision inspection component has descended to the correct position, the industrial control computer sends a control command to the linear drive 2, ordering the linear drive 2 to stop. At this time, the lens tube of the optical hard tube lens 7 extends into the inspection space and takes a picture through the lens located at the end of the lens tube of the optical hard tube lens 7. Based on the photo data captured by the optical hard tube lens 7, the industrial control computer determines whether the assembly of the sealing ring inside the workpiece 8 meets the production requirements.

[0056] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
