Description

Technical Field

[0001] The utility model relates to the technical field of rod-shaped component detection, in particular to a rod-shaped component detection tool. Background Art

[0002] Currently, some rod-shaped components that require precise inspection mainly rely on imagers for inspection. For rod-shaped components, such as screws, the bottom diameter, thread angle, tooth height and pitch of the screws need to be inspected. However, the current tooling for positioning rod-shaped components is only a simple V-shaped tooling, which can only detect the relatively simple bottom diameter of screws. Moreover, whether it is a routine inspection or an inspection for some complex dimensions, it is necessary to align and level the tooling for placing the rod-shaped component multiple times before inspection. The tooling for placing the rod-shaped component must be aligned, and the axial direction of the rod-shaped component must be aligned with the reference line on the image of the imager for a second time. The operation process is complicated. At the same time, the tooling currently used is a solid structure, and the beam of the imager cannot penetrate the tooling. Therefore, only part of the structure of the rod-shaped component can be protruded from the V-shaped tooling, and the beam at the bottom of the operating table can capture the rod-shaped component. When the rod-shaped component is not long enough, it is often necessary to use plasticine to fix the rod-shaped component. Doing so not only causes contamination to the rod-shaped component, but also causes measurement errors due to uneven adhesion of the plasticine. Especially when testing the tooth angle of threaded parts, the rod needs to be raised to a certain angle and then fixed with plasticine. Since the optimal detection angle of the screw is uncertain, and the plasticine will have a certain rebound due to factors such as temperature and shape, it is easy to cause the rod to shake. It needs to be placed multiple times to accurately find the best measurement angle. Utility Model Content

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] This embodiment provides a rod-shaped component detection tool, such as Figure 1-Figure 3 As shown, it includes a base 1, a bracket 2 and a slider 3. The base 1 is in the shape of a flat plate, and an opening is provided in the middle of the base 1 that passes through its upper and lower surfaces. The bracket 2 is arranged in the opening, and one end is rotatably connected to the base 1. The bracket 2 is provided with a positioning portion for placing the rod-shaped component to be detected. The middle part of the bracket 2 is provided with a third opening 21, and an external light source can shine on the rod-shaped component through the opening and the third opening 21. The slider 3 is slidably connected to the base 1. The slider 3 can be supported below the bracket 2 and is used to adjust the rotation angle of the bracket 2 relative to the base 1 to control the external light source to shine on the rod-shaped component to form the desired image.

[0039] This embodiment specifically provides a tool for assisting an imager in rapidly inspecting rod-shaped components. The rod-shaped component is placed above an opening in base 1 and a third opening 21 in bracket 2. The imager's light beam can penetrate the opening and third opening 21 and illuminate the rod-shaped component. Bracket 2 is pivotally connected to base 1. Adjusting the rotation angle of bracket 2 relative to base 1 facilitates adjusting the position of the light beam on the rod-shaped component, allowing the imager to capture the desired image of the rod-shaped component and the optimal inspection angle, enabling rapid and accurate inspection.

[0040] In this embodiment, the rotation angle of the bracket 2 relative to the base 1 is adjusted by the slider 3, which is easy to operate. When the slider 3 is not placed under the bracket 2, the bracket 2 is horizontally arranged at the opening of the base 1, providing a zeroing guarantee for the bracket 2 with adjustable angle. The bracket 2 is zeroed when it touches the bottom, so that the bracket 2 and the imaging instrument operating table are kept in a horizontal state, which is conducive to the detection of the rod-shaped component in a horizontal state. When the slider is placed under the bracket, the upward angle of the bracket 2 can be adjusted by adjusting the placement of the slider 3 under the bracket 2, thereby adjusting the upward angle of the rod-shaped component on the bracket 2, making it easier for the imaging instrument to capture the image of the required rod-shaped component. The rod-shaped component in this embodiment can be a screw product. The screw is placed at an angle relative to the light beam, so that the full appearance of the screw and the best detection angle and position can be presented under the capture lens of the imaging instrument, facilitating the precise detection of the screw, such as the thread angle.

[0041] In this embodiment, Figure 2 As shown, the openings include a first opening 11 and a second opening 12 that are interconnected. The diameter of the first opening 11 is larger than that of the second opening 12. A step is provided at the end surface where the first and second openings 11 and 12 meet, and the bracket 2 is mounted on the step. The step is horizontal and supports the bracket 2, ensuring that the adjustable angle bracket 2 returns to zero. Furthermore, the openings at the center of the base 1 and bracket 2 also reduce the weight of the inspection tooling.

[0042] In this embodiment, Figure 1 and Figure 2 As shown, the slider 3 is U-shaped and includes two connecting arms 31. The slider 3 is buckled on the base 1, and the two connecting arms 31 are slidably connected to the base 1. The present application does not impose any specific restrictions on the structure of the slider 3, and it only needs to be able to slide relative to the base 1 under the bracket 2.

[0043] In this embodiment, the base 1 and the bracket 2 are both rectangular parallelepiped in shape, with the length of the base 1 parallel to the length of the bracket 2, and the width of the base 1 parallel to the width of the bracket 2. The slider 3 also includes a connecting rod 32 connecting the two connecting arms 31, and the axis of the connecting rod 32 is parallel to the width of the base 1.

[0044] In this embodiment, Figure 2 As shown, bracket 2 and base 1 are rotatably connected via shaft 13. As shown, bracket 2 is provided with a second through-hole that extends through the sidewall of bracket 2 in the width direction, with its axis parallel to the width direction of bracket 2. Base 1 is provided with a first through-hole that extends through both sidewalls in the length direction of base 1, with its axis parallel to the width direction of base 1. Shaft 3 is inserted into the first and second through-holes, connecting bracket 2 to base 1.

[0045] In this embodiment, Figure 2 As shown, the side wall of the base 1 is provided with a groove 14 extending along its length direction, and the side wall of the connecting arm 31 is provided with a protrusion 311. The protrusion 311 is arranged in the groove 14 and can slide in the groove 14 along the length direction of the base 1, thereby realizing the sliding of the slider 3 relative to the length direction of the base 1.

[0046] In this embodiment, a threaded hole is provided on the connecting arm 31 , and a bolt is passed through the threaded hole to lock the slider 3 and the base 1 .

[0047] In this embodiment, the positioning portion includes a sliding assembly, which is provided on the bracket 2 for supporting the rod-shaped component, and the sliding assembly can move along the length direction of the bracket 2. There are preferably two sliding assemblies, which are spaced apart along the length direction of the bracket 2, and the two sliding assemblies are respectively supported at both ends of the rod-shaped component. Depending on the specifications of the rod-shaped component to be measured, in other embodiments, the number of sliding assemblies may be one or more than two. When the length of the rod-shaped component is relatively short, one sliding assembly can meet the requirements. When the length of the rod-shaped component is relatively long, at least two sliding assemblies should be selected, and the two sliding assemblies are respectively supported at both ends of the rod-shaped component. When the rod-shaped component is longer or has a smaller diameter and is easy to bend, three sliding assemblies can be selected, and the three sliding assemblies are respectively supported at both ends and the middle of the rod-shaped component. The sliding setting of the sliding assembly can adapt to rod-shaped components of different length specifications.

[0048] In this embodiment, Figure 1 and Figure 2 As shown, the sliding assembly includes a slide 22. The slide 22 is U-shaped and includes a crossbeam 221 and two vertical plates 222 perpendicularly connected to the ends of the crossbeam 221. The two vertical plates 222 are slidably connected to the bracket 2. The crossbeam 221 is used to support the rod-shaped component. The slide 22 is buckled onto the bracket 2.

[0049] In this embodiment, the rod-shaped component inspection fixture further includes multiple limiters, all of which are connected to bracket 2 and are used to limit the sliding of slide plate 22. When slide block 3 is supported below bracket 2 so that bracket 2 rotates a certain angle relative to base 1, there is a risk that slide plate 22, which is inverted on bracket 2, will slide downward. The limiters are used to prevent slide plate 22 from sliding downward.

[0050] Specifically, if Figure 1 and Figure 2 As shown, the limiting member is a limiting pin 24. The bracket 2 is provided with a plurality of third assembly holes 25 symmetrically and spaced apart along its length on both sides of the third opening 21 in the width direction. The limiting pin 24 is connected to the third assembly holes 25. When the limiting pin 24 is inserted into the third assembly hole 25, its outer surface abuts against the slide plate 22 to limit the slide plate 22 from sliding.

[0051] In this embodiment, Figure 1 and Figure 2 As shown, the sliding assembly further includes a V-shaped bracket 23, which is provided on the crossbeam 221 and is used to support the rod body of the rod-shaped component. The V-shaped bracket 23 includes a V-shaped notch, which can clamp the rod body of the rod-shaped component to prevent the rod-shaped component from shaking.

[0052] Depending on the specifications of the rod-shaped component, the number of V-shaped brackets 23 used can be one, two, or more. When the rod-shaped component is short, one or two V-shaped brackets 23 are sufficient. When the rod-shaped component is long, at least two V-shaped brackets 23 should be used. When the rod-shaped component has a small diameter, or when two or more rod-shaped components need to be measured simultaneously, two or more sets of V-shaped brackets 23 can be selected to accommodate multiple rod-shaped components to be measured, depending on the number of rod-shaped components to be measured.

[0053] In this embodiment, Figure 2 As shown, the crossbeam 221 is provided with a plurality of second assembly holes 2211, which are used to install the V-shaped bracket 23. The number of the V-shaped bracket 23 and the second assembly holes 2211 can be selectively used according to the specifications of the rod-shaped component.

[0054] In this embodiment, Figure 3 As shown, a plurality of first assembly holes 15 are provided on the upper surface of the base 1 along its length, and the V-shaped brackets 23 can be connected to the first assembly holes 15. The first assembly holes 15 can be used to temporarily place extra V-shaped brackets 23 and reduce the weight of the tooling.

[0055] In this embodiment, Figure 3 As shown, a cross reference line 16 is provided on the upper surface of the base 1. Two perpendicular intersecting lines of the cross reference line 16 are arranged parallel to the length and width of the base 1, respectively. Using an imager to capture the cross reference line 16 and aligning the coordinate line on the screen with the cross reference line 16 confirms that the rod-shaped component inspection fixture and the rod-shaped component to be clamped later are horizontal, saving inspection time.

[0056] In this embodiment, Figure 3As shown, the upper surface of the base 1 is provided with a numerical scale. The numerical scale includes two numerical scales, namely the stroke value of the slider 3 sliding along the base 1 and the angle value of the bracket 2 rotating upward relative to the base 1, wherein the stroke value and the angle value correspond one to one. The initial position of the slider 3 is flush with the end of the base 1 away from the rotation connection with the bracket 2. When the slider 3 slides toward the rotation connection end of the base 1 and the bracket 2, the bracket 2 is lifted. As the slider 3 gradually moves toward the rotation connection end, the bracket 2 will be slowly lifted to a certain angle, and the lifted angle value is calculated using the displacement of the slider 3 toward the rotation connection end. In this embodiment, the numerical scale is preferably the angle value of the bracket 2 rotating upward relative to the base 1. The stroke value of the slider 3 moving toward the rotation connection end is converted into an angle value, and the angle value is engraved on the base 1 for easy reading, and the slider 3 is moved.

[0057] The working process of this embodiment is as follows: Assemble the base 1 and the bracket 2 so that the bracket 2 can be easily rotated up and down. According to the rod-shaped components of different length specifications, select the appropriate number of slides 22 and V-shaped brackets 23, insert the V-shaped bracket 23 into the second assembly hole 2211 on the beam 221, select the best spacing by sliding the slide 22, and then insert the limit pin 24 into the third assembly hole 25 reserved in advance on the bracket 2 to limit the slide 22. When it is necessary to measure the thread angle of the screw, slide the slider 3 to move it to the left and lift the bracket 2. When the slider 3 moves to the appropriate stroke, the bracket 2 will rotate to a reasonable angle value. At this time, the best detection angle and position of the screw will be projected on the imager. Tighten the bolts on the connecting arm 31, lock the slider 3 and the base 1, and detect the thread angle of the screw.

[0058] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
