Description

TECHNICAL FIELD

[0001] The utility model relates to industrial image acquisition field especially, and relates to a kind of adjustable inner hole image acquisition device. BACKGROUND

[0002] In the field of industrial production and detection, it is crucial to accurately collect images of workpiece inner holes. It not only concerns product quality detection, but also plays a key role in optimizing the production process. However, the existing inner hole image acquisition device has many problems to be solved.

[0003] Traditional inner hole image acquisition devices lack flexibility when dealing with different specifications of workpieces. The camera and light source positions of most devices are relatively fixed, making it difficult to adjust according to the size, depth, and other differences of workpiece inner holes. This results in poor image quality, such as uneven lighting and blurred imaging, making it difficult for detection personnel to accurately determine whether there are defects in the workpiece inner hole, thereby affecting product quality control.

[0004] At the same time, the replacement process of the collection lens of the traditional device is extremely tedious. When facing different specifications of inner holes, the staff often needs to use various tools to perform complex disassembly and installation operations. Frequent manual disassembly and assembly of the lens not only consumes time and effort, but also easily causes damage to the lens or inaccurate installation due to improper operation, thereby affecting the accuracy of image acquisition.

[0005] Therefore, it is necessary to provide a new adjustable inner hole image acquisition device to solve the above technical problems. SUMMARY

[0006] To solve the above technical problems, the utility model provides an adjustable inner hole image acquisition device.

[0007] The utility model provides an adjustable inner hole image acquisition device, which comprises a base, a stand fixedly connected to the base, a top plate fixedly connected to the top end of the stand, a middle column fixedly connected between the top plate and the base, a camera provided at the upper position of the middle column, a lamp frame slidingly connected to the lower end of the middle column, and a ring-shaped light source installed in the lamp frame.

[0008] Preferably, the adjusting disc is provided with a plurality of embedded grooves, and the plurality of collection lenses are fixedly installed in the plurality of embedded grooves. The plurality of embedded grooves are arranged in an equidistant ring shape.

[0009] Preferably, the adjusting assembly includes a main gear, which is fixedly connected to the top end of the main shaft, and a secondary gear is provided on one side of the main gear, which meshes with the main gear.

[0010] Preferably, a motor is installed and connected to the other end of the bracket, the output shaft of the motor extends through to the other side of the bracket, and the output end of the motor is fixedly connected to the middle of the auxiliary gear.

[0011] Preferably, a main vertical shaft is rotatably connected between the top plate and the base, a main handwheel is installed at the top of the main vertical shaft, the main vertical shaft is a threaded shaft, the lamp frame is provided with a main threaded opening, and the lamp frame is threadedly connected to the main vertical shaft.

[0012] Preferably, a secondary vertical shaft is rotatably connected between the top plate and the base, a mounting bracket is provided on the secondary vertical shaft, a secondary handwheel is installed and connected at the top end of the secondary vertical shaft, the secondary vertical shaft is a threaded shaft, the mounting bracket is provided with a secondary threaded opening, and the mounting bracket is threadedly connected to the secondary vertical shaft.

[0013] Preferably, the mounting bracket is provided with a mounting slot, and the camera is fixedly mounted in the mounting slot.

[0014] Compared with related technologies, the adjustable internal hole image acquisition device provided by this utility model has the following beneficial effects:

[0015] 1. This utility model utilizes a dual-wheel adjustment method. Rotating the main handwheel drives the main vertical shaft, allowing the lamp frame and ring light source to slide longitudinally. Simultaneously, rotating the auxiliary handwheel drives the auxiliary vertical shaft, causing the mounting bracket and camera to move synchronously. This allows for quick and convenient adjustment of the relative distance between the camera and the ring light source. This design enables the device to flexibly change the positional relationship between the camera and the light source according to the size, depth, and other characteristics of the inner hole of workpieces of different specifications. This ensures that during image acquisition, the camera can obtain clear and accurate images of the inner hole, and the ring light source can provide uniform and suitable illumination conditions. No complex installation and debugging are required; simply rotating the main and auxiliary handwheels allows for quick adjustment to the optimal acquisition position, greatly improving the device's adaptability to workpieces of different specifications, reducing equipment adjustment costs and time consumption due to workpiece size differences, and increasing production efficiency.

[0016] 2. This invention controls the motor to rotate the main gear, which in turn drives the main shaft and adjustment disc, enabling rapid switching between different lens specifications. In practical applications, different inner diameters may require lenses with different focal lengths and angles to achieve the desired image quality. There's no need for manual, tedious lens disassembly and adjustment; simply starting the motor quickly rotates the lens suitable for a specific inner diameter to the camera's shooting position. This automated lens switching method not only reduces the risk of errors and damage from manual operation but also improves the continuity and efficiency of image acquisition. It is particularly suitable for production and testing processes that require frequent lens changes to accommodate different inner diameters, providing a strong guarantee for improving production quality and testing efficiency.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please refer to the following: Figures 1 to 3 An adjustable internal image acquisition device includes: a base 1, a support frame 2 fixedly connected to the base 1, a top plate 21 fixedly connected to the top of the support frame 2, a central column 22 fixedly connected between the top plate 21 and the base 1, a camera 3 positioned above the central column 22, a lamp frame 31 slidably connected to the lower end of the central column 22, and a ring light source 32 installed in the lamp frame 31; and a quick switching mechanism including a bracket 4, one end of the bracket 4 fixedly connected to the outer wall of the camera 3, the other end of the bracket 4 rotatably connected to a main shaft 41, an adjustment disk 42 fixedly connected to the lower end of the main shaft 41, multiple acquisition lenses 43 mounted on the adjustment disk 42, and an adjustment assembly between the main shaft 41 and the bracket 4.

[0023] In the specific implementation process, such as Figure 1 and Figure 2 As shown, the adjustment disk 42 is provided with multiple fitting slots, and multiple acquisition lenses 43 are fixedly installed in the multiple fitting slots respectively. The multiple fitting slots are arranged in an equidistant ring.

[0024] It should be noted that when the main shaft 41 rotates relative to one end of the bracket 4, the adjustment disk 42 at the lower end of the main shaft 41 rotates accordingly, which allows for quick adjustment of the acquisition lens 43 of different specifications to the shooting position of the camera 3, so as to make it suitable for use with inner holes of different specifications.

[0025] refer to Figure 2 and Figure 3 As shown, the adjustment assembly includes a main gear 5, which is fixedly connected to the top end of the main shaft 41. A secondary gear 51 is provided on one side of the main gear 5, and the secondary gear 51 meshes with the main gear 5.

[0026] refer to Figure 2 and Figure 3 As shown, a motor 52 is installed and connected at the other end of the bracket 4. The output shaft of the motor 52 extends through to the other side of the bracket 4, and the output end of the motor 52 is fixedly connected to the middle of the auxiliary gear 51.

[0027] It should be noted that: the control motor 52 works, causing its output shaft to drive the auxiliary gear 51 to rotate, which in turn drives the main gear 5, which meshes with it, to rotate, so that the main gear 5 drives the main shaft 41 to rotate relative to one end of the bracket 4.

[0028] refer to Figure 1 and Figure 2 As shown, a main vertical shaft 6 is rotatably connected between the top plate 21 and the base 1. A main handwheel 61 is installed and connected at the top of the main vertical shaft 6. The main vertical shaft 6 is a threaded shaft. The lamp frame 31 is provided with a main threaded opening. The lamp frame 31 is threadedly connected to the main vertical shaft 6.

[0029] It should be noted that: rotating the main handwheel 61 drives the main vertical shaft 6 to rotate, causing the lamp frame 31 to slide stably relative to the central column 22, and the lamp frame 31 drives the ring light source 32 to adjust its position longitudinally.

[0030] refer to Figure 1 and Figure 2 As shown, a secondary vertical shaft 7 is rotatably connected between the top plate 21 and the base 1. A mounting bracket 71 is provided on the secondary vertical shaft 7. A secondary handwheel 72 is installed and connected at the top of the secondary vertical shaft 7. The secondary vertical shaft 7 is a threaded shaft. A secondary threaded opening is provided on the mounting bracket 71.

[0031] It should be noted that: by simultaneously rotating the auxiliary handwheel 71 to drive the auxiliary vertical shaft 7 to rotate, the mounting bracket 71 drives the camera 3 to move stably relative to the central column 22, thereby enabling quick adjustment of the relative distance between the camera 3 and the ring light source 32.

[0032] refer to Figure 2 As shown, the mounting bracket 71 has a mounting slot, and the camera 3 is fixedly mounted in the mounting slot.

[0033] It should be noted that the camera 3 is fixedly installed in the mounting slot, so that the movement of the mounting bracket 71 can move the camera 3 accordingly and adjust its position.

[0034] The working principle of the adjustable internal hole image acquisition device provided by this utility model is as follows: rotating the main handwheel 61 drives the main vertical shaft 6 to rotate, causing the lamp frame 31 to slide stably relative to the central column 22. The lamp frame 31 drives the ring light source 32 to adjust its position longitudinally. At the same time, rotating the auxiliary handwheel 71 drives the auxiliary vertical shaft 7 to rotate, causing the mounting bracket 71 to drive the camera 3 to move stably relative to the central column 22. This allows for quick adjustment of the relative distance between the camera 3 and the ring light source 32, making it suitable for image acquisition of internal holes of workpieces of different specifications.

[0035] The control motor 52 operates, causing its output shaft to drive the auxiliary gear 51 to rotate, which in turn drives the main gear 5 meshing with it to rotate. The main gear 5 drives the main shaft 41 to rotate relative to one end of the bracket 4, causing the adjustment disc 42 at the lower end of the main shaft 41 to rotate accordingly. This allows for quick adjustment of the acquisition lens 43 of different specifications to the shooting position of the camera 3, making it suitable for use with different specifications of inner holes. This eliminates the need for tedious disassembly and adjustment by the staff, making it very convenient.
