Specific implementation manner

[0031] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0032] Please refer to Figure 1 , a thread detection fixture in this embodiment includes a bottom plate 1. Bases 2 are fixedly arranged around the lower surface of the bottom plate 1. A main body 3 of the detector is fixedly arranged on the upper surface of the bottom plate 1. A workbench 4 is rotatably connected to the bottom plate 1, and a fixing mechanism 5 is arranged on the workbench 4.

[0033] It should be noted that through the fixing mechanism 5, it is convenient for the staff to fix connectors of different specifications and types, which is convenient for subsequent cooperation with the main body 3 of the detector to perform thread detection on the connectors, improving the applicability and detection efficiency of the device.

[0034] Please refer to Figures 1-4, in order to improve the applicability and detection efficiency of the device, the fixing mechanism 5 in this embodiment includes four fixing blocks 501 fixed on the upper surface of the workbench 4, an adjusting component, a moving component, and a clamping component. The adjusting component includes a motor 502, a rotating rod 503, a first gear 504, two second gears 505, and two bidirectional screws 506 fixed on the front surface of the fixing block 501. The output shaft of the motor 502 is fixed with a rotating rod 503 that penetrates one end into the inner cavity of the fixing block 501 and is rotatably connected to the inner rear side wall of the fixing block 501 through a bearing, so that the rotating rod 503 can be more stable when rotating. The outer surface of the rotating rod 503 is fixed to the inner wall of the axis of the first gear 504. A through hole is opened on the front surface of the fixing block 501, and the through hole is rotatably connected to the rotating rod 503. The bidirectional screw 506 is rotatably connected between the front and rear sides of the inner cavity of the fixing block 501 through a bearing, so that the bidirectional screw 506 can rotate more stably when being forced to rotate. The second gear 505 meshes with the first gear 504, and the inner wall of the axis of the second gear 505 is fixed to the outer surface of the bidirectional screw 506. By starting the motor 502 to drive the rotating rod 503 and the first gear 504 to rotate, the bidirectional screw 506 can be driven to rotate, providing a power source for the moving component.

[0035] Among them, the moving component includes two adjusting blocks 507 threadedly connected to the outer surface of the bidirectional screw 506, four hinge rods 508, two moving plates 509, four guiding blocks 510, and four connecting rods 512. The opposite sides of the two hinge rods 508 are respectively hinged to the opposite sides of the two adjusting blocks 507, and the opposite sides of the two hinge rods 508 are respectively hinged to the opposite sides of the two moving plates 509. The opposite sides of the front and rear two guiding blocks 510 are respectively fixed to the front and rear sides of the moving plate 509. Four adjusting holes are opened on the upper surface of the fixing block 501, and the adjusting holes are slidably connected to the connecting rods 512, facilitating the movement of the connecting rods 512 when being forced, and then driving the clamping component to move. The bottoms of the front and rear two connecting rods 512 are fixed to the upper surface of the moving plate 509. By driving the hinge rods 508 and the guiding blocks 510 to move through the adjusting blocks 507, the position of the clamping component can be adjusted, so as to clamp connecting pieces of different sizes subsequently, facilitating subsequent thread detection.

[0036] At the same time, two guiding grooves 511 are opened on both the front and rear sides of the inner cavity of the fixing block 501. The guiding grooves 511 are slidably connected to the guiding blocks 510, facilitating the guiding blocks 510 to move along the guiding grooves 511 following the movement of the moving plate 509, providing more support for the stable movement of the moving plate 509.

[0037] In addition, the clamping assembly includes an adjusting plate 513 fixed to the tops of the front and rear two connecting rods 512, two groups of moving blocks 514, two fixing plates 515, and two groups of springs 516. The opposite sides of the left and right two groups of moving blocks 514 are respectively fixed to the opposite sides of the two fixing plates 515. The opposite sides of the two moving blocks 514 are respectively fixed to the opposite sides of the two springs 516. By driving the adjusting plate 513 and the adjusting plate 513 through the connecting rod 512 for position adjustment, connectors of different sizes can be fixedly clamped, thereby improving the flexibility of the device and reducing the production cost.

[0038] In addition, two groups of moving grooves 517 are formed on the opposite sides of the two adjusting plates 513. The moving grooves 517 are slidably connected to the moving blocks 514. The cross-sections of the moving grooves 517 and the moving blocks 514 are both convex-shaped, facilitating the moving blocks 514 to always move inside the moving grooves 517 without slipping out. The opposite sides of the two springs 516 are respectively fixed to the opposite sides of the inner cavities of the two moving grooves 517. Through the elastic force of the springs 516, a buffer is provided for the contact between the fixing plate 515 and the connector, which can further protect the device and the connector to a certain extent.

[0039] In this embodiment, through the cooperation of the adjusting assembly, the moving assembly, and the clamping assembly, the device can clamp and fix connectors of various sizes. At the same time, in cooperation with the main body 3 of the detector, it further meets the detection requirements for multi-variety and small-batch production, and also saves the production cost.

[0040] All the electrical components mentioned in the text are electrically connected to the controller and the power supply. The control mode of the present utility model is controlled by the controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of the power supply also belongs to the common knowledge in the art. And the present utility model is mainly used to protect the mechanical device, so the control mode and the circuit connection of the present utility model will not be explained in detail.

[0041] The working principle of the above embodiment is as follows:

[0042] When it is necessary to conveniently fix the connecting piece to be detected, first start the motor 502 to drive the rotating rod 503 and the first gear 504 to rotate, so that the two second gears 505 can rotate to drive the two bidirectional screws 506 to rotate, and then the front and rear adjusting blocks 507 can move away from or towards each other, so as to drive the hinge rod 508, the moving plate 509 and the connecting rod 512 to move. At this time, the guide block 510 moves along the guide groove 511 following the movement of the moving plate 509, providing more support for the stable movement of the moving plate 509. Furthermore, the distance between the two connecting rods 512 can be adjusted, that is, the distance between the two adjusting plates 513 and the fixing plate 515 can be adjusted. Furthermore, the detection fixture can be adjusted according to the size of the connecting piece, so as to be applicable to the detection of more different specifications and types of threaded connecting pieces, and can also detect multiple threaded connecting pieces at the same time, further improving the detection efficiency and accuracy. And during the clamping process of the two fixing plates 515 on the connecting pieces of different sizes, the spring 516 will be elastically deformed, buffering the contact between the fixing plate 515 and the connecting piece, avoiding rigid contact between the two, further protecting the device and the connecting piece, and can also effectively fix the connecting pieces to be detected of different sizes, facilitating subsequent detection.
