Description

Technical Field

[0001] This utility model relates to the field of component testing technology, specifically a component internal and external surface testing device. Background Technology

[0002] In modern industrial production, the quality of parts directly affects the performance and reliability of products. Precise inspection of the inner and outer surfaces of parts has become a key step in the production process, especially for special structural parts in aerospace, automobile manufacturing and other fields, such as parts with eccentric openings at the top. Their complex structural design places higher demands on inspection equipment.

[0003] However, existing component inspection devices generally have limitations. Most devices are only suitable for conventional symmetrical components. For components with special shapes such as eccentric openings at the top, they cannot achieve stable clamping and eccentric positioning, making it difficult to fully cover the inner and outer surfaces during inspection and creating blind spots. Traditional inspection methods cannot take into account both the eccentric characteristics of such components and the inspection requirements for inner and outer surfaces. Although some devices can perform inspection, they require multiple manual adjustments to the clamping position, resulting in low efficiency and the inspection accuracy being greatly affected by human factors. In addition, existing devices lack clamping stability when dealing with curved or angular sidewall components, which can easily cause inspection errors and cannot meet the high-quality inspection requirements of modern industry for special components. Therefore, we propose a component inner and outer surface inspection device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for inspecting the inner and outer surfaces of components, thus solving the aforementioned problems.

[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: a device for inspecting the inner and outer surfaces of components, comprising:

The four clamping devices are axially symmetrically distributed inside the rotating base, and the bottom side of the top eccentrically opened component is in contact with the four clamping devices.

[0008] Preferably, the top side of the testing platform is provided with an inverted L-shaped plate, and a group of industrial cameras are provided on the side wall of the plate. The industrial camera group is in a vertical position. A multi-stage electric push rod is provided at the top center of the inverted L-shaped plate, and an internal detector is provided at the bottom push rod shaft end of the multi-stage electric push rod. The multi-stage electric push rod is axially concentric with the rotating base.

The active component of the clamping device is the clamping rod, which is inserted into the interior of the rotating base through a mating hole. The section of the clamping rod inside the rotating base is a threaded rod. The rotating base is threadedly connected to the sliding member, and the clamping block is rotatably connected to the top of the sliding member.

[0022] 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.

[0023] Please see Figure 1-6 A device for inspecting the inner and outer surfaces of components, comprising:

[0024] The testing table 1 and the top eccentric opening component 5 are placed inside the testing table 1.

[0025] An adaptive clamping rotation assembly is installed inside the testing table 1. The adaptive clamping rotation assembly includes a rotating base 2, a motor 9, and clamping devices. The bottom center of the rotating base 2 is welded to the top output shaft end of the motor 9, and the motor 9 is fixedly connected to the bottom end face of the testing table 1 by an adapter screw. The four clamping devices are symmetrically distributed inside the rotating base 2, and the bottom side of the top eccentrically opened component 5 is in contact with the four clamping devices.

[0026] Furthermore, the top side of the inspection table 1 is provided with an inverted L-shaped plate. The side wall of the plate is provided with a group of industrial cameras 7 that are equidistantly distributed and are vertically arranged. The top center of the inverted L-shaped plate is provided with a multi-stage electric push rod 6, and the bottom push rod shaft of the multi-stage electric push rod 6 is provided with an internal detector 8. The multi-stage electric push rod 6 and the rotating base 2 are axially concentrically distributed. When the top eccentric opening component 5 is clamped by the clamping device, the internal detector 8 at the bottom of the multi-stage electric push rod 6 extends into the interior of the top eccentric opening component 5. When the adaptive clamping rotating assembly drives the fixed top eccentric opening component 5 to rotate, the internal detector 8 and the group of industrial cameras 7 can simultaneously scan and inspect the inside and outside of the top eccentric opening component 5.

[0027] Furthermore, the main body of the rotating base 2 is a hollow cylindrical structure, and four symmetrically distributed mating holes 10 are provided on the side wall of the rotating base 2. Four sets of symmetrically distributed sliding grooves 11 are provided on the top end face of the rotating base 2, and the sliding grooves 11 are connected to the interior of the rotating base 2. The rotating base 2 is driven by the output shaft of the motor 9, so that the rotating base 2, the four clamping devices and the top eccentric opening component 5 rotate at a uniform speed, and the rotating base 2 plays a supporting role.

[0028] Furthermore, the clamping device includes a clamping block 3, a clamping rod 4, and a sliding member 12. The active component of the clamping device is the clamping rod 4, which is inserted into the rotating base 2 through the mating hole 10. The section of the clamping rod 4 corresponding to the inside of the rotating base 2 is a threaded rod. The rotating base 2 is threadedly connected to the sliding member 12. The clamping block 3 is rotatably connected to the top of the sliding member 12. When clamping and fixing the top eccentric opening component 5, the top eccentric opening component 5 is placed on the top of the rotating base 2. By rotating the clamping rods 4 of the four clamping devices, the four clamping blocks 3 clamp and fix the bottom of the top eccentric opening component 5. During the rotation of the clamping rods 4, the top opening of the top eccentric opening component 5 is aligned with the internal detector 8 of the bottom output shaft of the multi-stage electric push rod component 6, which facilitates the downward extension of the internal detector 8. Therefore, the top eccentric opening component 5 and the rotating base 2 are in a non-concentric state, which greatly improves the effective detection of the special component structure of the top eccentric opening component 5.

[0029] Furthermore, the bottom of the sliding member 12 is provided with a threaded bushing 13, which is threadedly connected to the clamping rod 4. The top two opposite sides of the threaded bushing 13 are provided with sliders 14, which are slidably connected to the slide groove 11. There is a rectangular opening between the two sliders 14. A rectangular plate is welded to the top of the sliding member 12. A connecting rod 15 and a sliding rod 16 are welded to the top of the rectangular plate. Both the connecting rod 15 and the sliding rod 16 are in a vertical position. When the clamping rod 4 rotates, the threaded bushing 13 converts its circumferential rotation into the linear motion of the sliding member 12, thereby realizing the position adjustment of the clamping block 3. The sliding engagement between the slider 14 and the slide groove 11 effectively ensures the axial movement stability of the sliding member 12, prevents deviation and shaking, and prevents debris from falling onto the threaded rod of the clamping rod 4.

[0030] Furthermore, the side wall of the clamping block 3 is provided with two arc-shaped fixing blocks 17 distributed symmetrically on the axis, and a V-shaped opening 18 is opened between the two arc-shaped fixing blocks 17. The end face of the clamping block 3 is provided with a connecting hole 19, which is rotatably connected to the connecting rod 15. The end face of the clamping block 3 is provided with an arc-shaped groove 20, which is slidably connected to the sliding rod 16. The clamping block 3 can rotate around the connecting rod 15 at a small angle. The arc-shaped groove 20 plays a limiting role in the rotation angle, thus ensuring the quality of eccentric positioning and fixing of the special parts of the top eccentric opening component 5. The cooperation between the arc-shaped fixing block 17 and the V-shaped opening 18 effectively ensures the efficient fixing of the top eccentric opening component 5 on curved side walls and angular side walls, which is highly practical.

[0051] Arc groove 20: Arc groove 20 is provided on the end face of clamping block 3, and slides with sliding rod 16 inside to limit the rotation angle of clamping block 3 and ensure the quality of eccentric positioning and fixing of parts.

[0052] Working principle: Install the internal and external surface inspection device of the component correctly according to the diagram. First, place the component 5 with the eccentric opening at the top on top of the rotating base 2 inside the inspection table 1. Rotate the clamping rod 4. Since the section of the clamping rod 4 inserted into the rotating base 2 is a threaded rod and is threadedly engaged with the threaded bushing 13 at the bottom of the sliding part 12, when rotating, the threaded bushing 13 converts the circumferential rotation into the linear motion of the sliding part 12, driving the four clamping blocks 3 to move axially toward the component 5 with the eccentric opening at the top. Using the arc-shaped fixing block 17 and the V-shaped opening 18 on the side wall of the clamping block 3, the bottom of the component 5 is pressed and clamped. At the same time, the top opening of the component 5 is aligned with the internal inspection instrument 8 at the bottom of the multi-stage electric push rod component 6. At this time, the motor 9 starts, driving the rotating base 2 and the component 5 fixed on it. The multi-stage electric push rod 6 drives the internal inspection instrument 8 to extend into the interior of the component 5. The industrial camera 7 set on the inverted L-shaped plate on the top side of the inspection table 1 is in a vertical position and works synchronously with the internal inspection instrument 8. During the rotation of the component 5, the internal inspection instrument 8 scans the inner surface and the industrial camera 7 captures the outer surface, acquiring images and data of the inner and outer surfaces of the component 5 to complete the all-round inspection. The sliding cooperation between the bottom slider 14 of the sliding component 12 and the sliding groove 11 of the rotating base 2 ensures its axial movement is stable, prevents deviation and shaking, and can block debris from entering and affecting the operation of the clamping rod 4. The clamping block 3 rotates with the connecting rod 15 through the connecting hole 19 and slides with the sliding rod 16 through the arc groove 20, and can rotate at a small angle to achieve precise positioning and fixation of the eccentric component.
