Description

Technical Field

[0001] This utility model relates to the field of quality inspection tooling technology, and in particular to a quality inspection tooling for irregularly shaped parts. Background Technology

[0002] In fields such as machinery manufacturing and automotive parts, irregularly shaped parts (such as irregular curved surface structural parts and connectors with asymmetrical holes) are increasingly widely used because they can adapt to complex assembly scenarios. However, the non-standardized structure of irregularly shaped parts poses many challenges to their quality inspection process. Traditional manual visual inspection methods are easily affected by subjective experience and visual fatigue, making it difficult to accurately identify dimensional deviations and surface defects in difficult-to-inspect areas such as complex curved surfaces and asymmetrical holes, resulting in a high risk of misjudgment.

[0003] Meanwhile, existing quality inspection methods lack dedicated tooling support for irregularly shaped parts, the position adjustment of inspection equipment is not flexible enough, making it difficult to achieve multi-directional inspection, and most tooling does not take into account both inspection and fixation functions. Irregularly shaped parts are prone to displacement during inspection, further aggravating inspection deviations. In addition, some tooling structures are rigidly designed and space is limited, making it difficult to remove irregularly shaped parts after inspection, affecting overall inspection efficiency. Utility Model Content

[0004] This utility model proposes a quality inspection fixture for irregularly shaped parts to solve the problems of existing quality inspection equipment being unable to perform multi-directional inspections and the difficulty in picking up irregularly shaped parts during inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a quality inspection fixture for irregularly shaped parts, including a base, a fixed support plate above the base, and a receiving groove on the upper surface of the fixed support plate, and further comprising:

[0006] The movable bracket is hinged within the receiving groove;

[0007] Two movable detection components are rotatably mounted on the upper end face of the movable bracket. Each movable detection component includes an industrial camera and a telescopic part, through which the detection position of the industrial camera can be adjusted.

[0008] The detection clamping component includes a movable part and two columns. An infrared transmitter is installed on one column, and an infrared receiver is installed on the other column. The movable part adjusts the lifting and spacing of the two columns.

[0009] Preferably, baffles are fixed at both ends of the upper surface of the fixed support plate, and the height of the baffles is greater than the thickness of the irregular part to be inspected.

[0010] Preferably, the active detection component further includes a rotating column, which is rotatably connected to the upper end face of the baffle, and a support strip is fixed to the top of the rotating column.

[0011] Preferably, the telescopic part includes:

[0012] The first telescopic rod is installed on the upper end face of the support bar;

[0013] An L-shaped mounting plate is installed at the end of the first telescopic rod, and the industrial camera is mounted on the L-shaped mounting plate.

[0014] Preferably, one end of the L-shaped mounting plate is fixed with a guide bar, and a guide groove is formed in the middle of the support bar along the length direction.

[0015] Preferably, the movable part includes a bidirectional telescopic rod and a second telescopic rod. The column is vertically mounted on the end of the bidirectional telescopic rod via a mounting block. A groove is provided on the base, and the second telescopic rod is installed in the groove, with its top end connected to the bidirectional telescopic rod.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] (1) In this application, the industrial camera can be flexibly adjusted in position through the telescopic part, and the rotating column can drive the support bar to rotate. It can capture details such as the surface contour and hole edge of the irregular part from multiple positions. After the high-definition image is transmitted to the computer, it can accurately identify problems such as size deviation and surface defects through program analysis, avoiding subjective errors of manual visual inspection. It is especially suitable for difficult-to-inspect parts such as complex curved surfaces and asymmetrical holes of irregular parts.

[0018] (2) In this application, the movable bracket is hinged in the receiving groove of the fixed bracket. After the inspection is completed, the bracket can be rotated to quickly remove the irregular parts, avoiding the difficulty of removing parts due to the limitation of the tooling structure. When the industrial camera is not used, the camera can be retracted by the first telescopic rod, and the bracket and camera can be rotated to the top of the baffle for storage by the rotating column. This saves space and avoids the inspection components from blocking the loading and unloading process of irregular parts, thus improving the overall smoothness of operation.

[0019] (3) During the inspection, the bidirectional telescopic rod pushes the column close to the hole wall of the irregular part, which can not only achieve accurate positioning of infrared detection, but also form a stable pressing effect on the irregular part, preventing the detection deviation caused by the displacement of the irregular part during the inspection process. Especially for thin and easily deformable irregular parts, it can effectively avoid the risk of misjudgment caused by workpiece shaking. Attached Figure Description

[0026] 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.

[0027] like Figures 1-4 As shown, a quality inspection fixture for irregularly shaped parts includes a base 1, a fixed support plate 2 above the base 1, and a receiving groove on the upper surface of the fixed support plate 2. It also includes a movable bracket 3, a detection clamping component 6, and two movable detection components 5. The movable bracket 3 is hinged within the receiving groove. The two movable detection components 5 are rotatably mounted on the upper end of the movable bracket 3. Each movable detection component 5 includes an industrial camera 55 and a telescopic part. The detection position of the industrial camera 55 can be adjusted via the telescopic part. The detection clamping component 6 includes a moving part and two columns 63. An infrared transmitter 64 is mounted on one column 63, and an infrared receiver 65 is mounted on the other column 63. The lifting and lowering of the two columns 63 can be adjusted via the moving part, and the distance between the two columns 63 can also be adjusted via the moving part.

[0028] See Figure 1As shown, baffles 4 are fixed at both ends of the upper surface of the fixed support plate 2. The height of the baffles 4 is greater than the thickness of the irregular part to be inspected. The movable inspection part 5 also includes a rotating column 51. The rotating column 51 is rotatably connected to the upper surface of the baffles 4. A support strip 52 is fixed at the top of the rotating column 51. The bottom end of the rotating column 51 can be connected to the baffles 4 through a bearing to achieve rotation, or a motor can be installed at the bottom end of the rotating column 51 to drive the rotating column 51 to rotate.

[0029] See Figure 1 As shown, the telescopic part includes a first telescopic rod 53 and an L-shaped mounting plate 54. The first telescopic rod 53 is an electric telescopic rod, which is installed on the upper end face of the support bar 52. The L-shaped mounting plate 54 is installed on the end of the first telescopic rod 53. The industrial camera 55 is installed on the L-shaped mounting plate 54. A guide bar 56 is fixed to one end of the L-shaped mounting plate 54. A guide groove is opened in the middle of the support bar 52 along the length direction. The guide bar 56 slides in the guide groove. When the first telescopic rod 53 is activated, the L-shaped mounting plate 54 can be moved by the first telescopic rod 53, thereby changing the position of the industrial camera 55 for detection. With the rotation of the rotating column 51, the position of the industrial camera 55 can be adjusted over a wider range.

[0030] When the industrial camera 55 is not in use, the first telescopic rod 53 can be used to retract the industrial camera 55. At the same time, the rotating column 51 can be used to rotate the support bar 52 and the industrial camera 55 to the top of the baffle 4, so that they can be stored on the side without obstructing the installation and removal of irregularly shaped parts.

[0031] It is also equipped with a computer, and high-definition images captured by the industrial camera 55 can be transmitted to the computer for analysis to determine whether they meet the standards.

[0032] See Figures 2-4 As shown, the movable part includes a bidirectional telescopic rod 61 and a second telescopic rod 62. Both the bidirectional telescopic rod 61 and the second telescopic rod 62 are electric telescopic rods. The uprights 63 are vertically installed at the end of the bidirectional telescopic rod 61 through the mounting block. The base 1 has a groove 101. The second telescopic rod 62 is installed in the groove 101, and the top end of the second telescopic rod 62 is connected to the bidirectional telescopic rod 61. The bidirectional telescopic rod 61 is raised and lowered through the second telescopic rod 62, and the distance between the two uprights 63 is adjusted through the bidirectional telescopic rod 61.

[0033] As described above, during use, the operator can first place the irregularly shaped part to be tested on the movable bracket 3 on the receiving groove, and use the second telescopic rod 62 to make the two columns 63 pass through the holes on the irregularly shaped part. Then, the two columns 63 are brought closer together to their respective holes by the bidirectional telescopic rod 61. On the one hand, the two columns 63 can press the irregularly shaped part to be tested, and on the other hand, the infrared transmitter 64 and infrared receiver 65 can be used to detect the distance between the two holes of the irregularly shaped part. Subsequently, the equipment will automatically compare the calculated actual distance with the preset standard distance parameter and display the test results (such as "qualified", "unqualified" and specific numerical deviation) on the operation interface. The operator needs to carefully check the test results. If the actual distance is within the allowable error range of the standard distance, it is determined that the distance between the two holes of the irregularly shaped part meets the standard; if it exceeds the error range, it is determined to be unqualified, and the relevant test data is recorded for subsequent analysis and processing of unqualified products.

[0034] After the test is completed, the column 63 can be lowered first, and then the hinged movable bracket 3 can be rotated to move the irregular part to be tested out of the receiving slot. Then the irregular part on the movable bracket 3 can be quickly removed, which is quite convenient.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
