Description

Technical Field

[0001] This utility model relates to the field of shock absorber manufacturing technology, and in particular to a shock absorber production weld inspection device. Background Technology

[0002] In the field of shock absorber manufacturing, lifting rings typically employ a ring-shaped or irregularly shaped structure, requiring welding to the cylinder to withstand vehicle vibration loads. Fork arms are mostly T-shaped or L-shaped joints, with a small welding contact area with the cylinder, making them prone to angular deviations due to repeated welding. Therefore, the welding quality of the lifting rings, fork arms, and cylinder directly affects the product's safety and durability.

[0003] In traditional production processes, welding and weld inspection are separated, relying mainly on manual experience and offline inspection equipment for weld inspection, which leads to the following problems:

[0004] 1. The existing production line uses a common positioning device to fix the workpiece. After welding, it needs to be manually transferred to an independent inspection station, which increases labor costs.

[0005] 2. Traditional inspection relies on manual visual inspection or sampling flaw detection (such as ultrasonic and magnetic particle testing), which has a high rate of missed detection and cannot intercept defective parts in real time, increasing rework costs.

[0006] 3. The welding process and weld inspection are disconnected, resulting in poor coordination with the production line and difficulty in adapting to the demands of high-speed production. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a weld inspection device that saves labor and improves efficiency.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0009] A weld inspection device includes a base, a turntable rotatably connected to the base, a plurality of workstations on the turntable, a fixture for holding workpieces on each workstation, and an industrial camera for inspecting welds when a workstation is rotated to that position connected to the base.

[0010] As a further improvement to the above technical solution:

[0011] Multiple baffles are evenly spaced on the turntable, and workstations are formed between the baffles.

[0012] A swing mechanism is connected to the base, and the industrial camera is fixed on the swing mechanism.

[0013] The swing mechanism includes a connecting seat, a swing cylinder, and a bracket. The connecting seat is fixedly connected to the base, the swing cylinder is fixedly mounted on the connecting seat, the bracket is fixedly connected to the swing cylinder and parallel to the axis of the turntable, and the industrial camera is fixedly mounted on the top of the bracket.

[0014] The swing cylinder switches between the left extreme position, the middle position and the right extreme position. When the swing cylinder swings to the middle position, it avoids the turntable. When the swing cylinder swings to the left extreme position and the right extreme position, the industrial camera takes pictures of the weld for inspection. The angle formed between the left extreme position, the right extreme position and the turntable axis is 60°.

[0015] The connecting seat is provided with a limiting post to limit the swing range of the swing cylinder.

[0016] The support is equipped with sensors for detecting workpieces.

[0017] The base is equipped with a motor that drives the turntable to rotate.

[0018] Compared with the prior art, the advantages of this utility model are:

[0019] This utility model's weld inspection device utilizes mature visual imaging technology from industrial cameras to inspect workpiece welds. Compared to manual inspection, it reduces labor costs, has a low rate of missed inspections, and is more efficient. Furthermore, by setting up multiple workstations on the turntable, this utility model can achieve simultaneous loading, welding, inspection, and unloading without interference, greatly improving production efficiency.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figures 1 to 3As shown, the weld inspection device of this embodiment includes a base 1, a turntable 2 rotatably connected to the base 1, multiple workstations 3 on the turntable 2, and a fixture 4 for holding the workpiece on each workstation 3. An industrial camera 5 is connected to the base 1 to perform weld inspection when the workstation 3 rotates to that position. This invention utilizes the mature visual imaging technology of the industrial camera 5 to inspect the weld of the workpiece. Compared with manual inspection, it reduces labor costs, has a low missed inspection rate, and is more efficient. Furthermore, by setting multiple workstations 3 on the turntable 2, this invention can achieve simultaneous loading, welding, inspection, and unloading without interference, greatly improving production efficiency.

[0027] In this embodiment, multiple baffle plates 21 are evenly spaced on the turntable 2, and workstations 3 are formed between each baffle plate 21. In this structure, the turntable 2 is divided into multiple workstations 3 by the baffle plates 21, and the workpieces on each workstation 3 undergo different processes simultaneously without affecting each other.

[0028] In this embodiment, a swing mechanism 6 is connected to the base 1, and an industrial camera 5 is fixedly mounted on the swing mechanism 6. The swing mechanism 6 includes a connecting seat 61, a swing cylinder 62, and a bracket 63. The connecting seat 61 is fixedly connected to the base 1, the swing cylinder 62 is fixedly mounted on the connecting seat 61, and the bracket 63 is fixedly connected to the swing cylinder 62 and parallel to the axis of the turntable 2. The industrial camera 5 is fixedly mounted on the top of the bracket 63. The swing cylinder 62 switches between the left extreme position, the middle position, and the right extreme position. The swing cylinder 62 swings to the middle position to avoid the turntable 2. The swing cylinder 62 swings to the left extreme position and the right extreme position so that the industrial camera 5 can take pictures and inspect the weld. The angle formed by the left extreme position, the right extreme position and the rotation axis of the turntable 2 is 60°. In this structure, for the inspection of circumferential welds, a single shooting position cannot capture the complete weld. At the same time, it is also necessary to prevent interference with the turntable 2. Therefore, a swing cylinder 62 is used to drive the bracket 63 to rotate the industrial camera 5. In the middle position (the initial position of the swing cylinder 62), it avoids the rotation path of the turntable 2. It takes a picture once at the left and right 30° angles, that is, at the left and right extreme positions, so that the optical axis of the industrial camera 5 forms an angle of ±30° with the weld center of the workpiece to determine the integrity of the weld.

[0029] In this embodiment, the connecting seat 61 is provided with a limiting post 611 to limit the swing range of the swing cylinder 62. The limiting post 611 is used to limit the swing range to ensure production safety.

[0030] In this embodiment, a sensor 631 for detecting workpieces is provided on the bracket 63. The workpiece is detected by the sensor 631, and the industrial camera 5 takes a picture after the workpiece is detected.

[0031] In this embodiment, a motor 7 is provided on the base 1 to drive the turntable 2 to rotate. The turntable 2 is driven to rotate by the motor 7, resulting in smooth rotation and precise control.

[0032] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
