Technical Field
[0001] This utility model relates to the field of mechanical testing technology, and in particular to a positioning fixture for batch testing of sockets. Background Technology
[0002] As a key structure widely used in electronic devices and mechanical components, the dimensional accuracy, position, and internal quality of sockets are crucial to product performance. During the production process, sockets need to be inspected in batches. Existing inspection methods mostly rely on manual labor or simple positioning fixtures, which have many shortcomings. On the one hand, manual inspection is inefficient and inconsistent, while simple positioning fixtures are unstable and the workpiece is prone to shaking during inspection, causing the physical probe or inspection block to misalign and resulting in misjudgment. On the other hand, the functions of existing technologies are very limited. Traditional physical inspection fixtures can only determine the diameter or depth of the hole, but cannot detect visual defects such as burrs, scratches, or blockages inside the socket. Independent visual inspection equipment usually lacks high-precision physical adaptation inspection functions and cannot verify mechanical dimensions at the same time. More importantly, after detecting defective products, existing fixtures lack clear and immediate feedback and auxiliary picking mechanisms, resulting in a disconnect between the inspection and sorting processes and low overall efficiency.
[0003] Therefore, this utility model proposes a positioning fixture for batch testing of sockets to overcome the shortcomings of the prior art. Utility Model Content

The detection mechanism also includes a groove on the left side of the fixture base plate, a sliding rod slidably embedded in the groove, and a detection block fixedly connected to the top of the sliding rod.
[0007] Furthermore, the quality inspection mechanism is securely connected to the fixture base plate via a connecting rod. The connecting rod has an elongated groove inside, and an indicator rod is slidably connected inside the groove. The quality inspection mechanism also includes a detection camera, an image processing board, and an indicator light. The detection camera is electrically connected to the image processing board, and the image processing board is electrically connected to the indicator light.

[0031] Working Principle: When using the device, the positioning fixture uses fixture base plate 1 as its main structure. Both the detection mechanism 2 and the quality inspection mechanism 3 are fixed above fixture base plate 1. First, regarding the workflow of the detection mechanism 2, the operator first places batches of workpieces to be inspected into the placement area 21 located on the top right side of fixture base plate 1. Placement area 21 provides an initial stacking area for the batch of workpieces. Then, the rotating shaft 22 connected to the middle side of placement area 21 is activated. The rotating shaft 22 drives the rotating suction rod 23 to rotate, moving the suction rod 23 above the workpieces in placement area 21. The suction rod 23 then adsorbs and fixes the workpieces to be inspected. After adsorbing the workpieces, the suction rod 23 rotates again around the rotating shaft 22, transferring the workpieces to the left side of fixture base plate 1. A support platform 24 is fixedly connected to the left side of fixture base plate 1. When the workpieces are transferred to... When the workpiece is above the support platform 24, the bottom of the workpiece engages with the engagement point 25 on the surface of the support platform 24. The shape of the engagement point 25 matches the bottom structure of the workpiece to be inspected. This matching engagement structure ensures that the workpiece is accurately fixed in the inspection position, providing a stable foundation for subsequent physical inspection and further improving the workpiece positioning stability. After the workpiece is positioned by the engagement point 25, the sliding rod 27 is pushed. The sliding rod 27 is slidably embedded in the groove 26 opened on the left side of the fixture base plate 1 corresponding to the inspection area. The sliding rod 27 can slide horizontally along the groove 26. The inspection block 28 fixedly connected to the top of the sliding rod 27 also moves horizontally until the inspection block 28 moves to the workpiece insertion hole position. The inspection block 28 completes the positioning inspection of the current single workpiece in the batch insertion holes through the adaptation test with the insertion hole.
[0032] Regarding the workflow of the quality inspection mechanism 3, the operator first places a batch of workpieces to be inspected into the area corresponding to the quality inspection mechanism 3 on the fixture base plate 1. The quality inspection mechanism 3 is securely connected to the fixture base plate 1 via a connecting rod 31. The connecting rod 31 is fixedly connected to the rear side of the fixture base plate 1 to ensure that the structure of the quality inspection mechanism 3 does not shift during operation. A long groove 32 is formed inside the connecting rod 31, and an indicator rod 33 is slidably connected inside the long groove 32. Before the inspection begins, the indicator rod 33 can be adjusted along the long groove 32 to the side of the workpiece to complete the auxiliary positioning of the workpiece. After the workpiece is positioned, the inspection camera 34 is activated and takes a picture of the workpiece's insertion hole to obtain the workpiece insertion hole. The detection camera 34 transmits the acquired image signal to the image processing board 35, which is electrically connected to the detection camera 34. The image processing board 35 analyzes and judges the received image signal. After the analysis is completed, the image processing board 35 outputs the judgment result. The reminder light 36, which is electrically connected to the image processing board 35, acts according to the judgment result. If the detection is qualified, the reminder light 36 keeps the green light on. If an unqualified socket is detected, the reminder light 36 immediately turns to flash red. This prompt enables efficient and accurate batch socket positioning detection. In addition, if the detection is unqualified, the staff can be reminded to pick it out by sliding the indicator rod 33 on the rear side of the fixture base plate 1.
