A positioning mechanism 2 is provided on the inner side of the L-shaped plate 8, and the positioning mechanism 2 is used to fix the metal part;

[0033] Specifically, starting the motor 3 can drive the first bevel gear 4 to rotate, thereby driving the second bevel gear 7 to rotate through meshing transmission, thereby driving the bidirectional threaded rod 5 to rotate, and through its threaded connection and the movement of the moving rod 6, driving the L-shaped plate 8 to move left and right. At this time, starting the electric telescopic rod 10 can drive the splint 11 to move to fix the workpiece, and flip the workpiece over by rotating the rotating cover 9, so as to facilitate the detection of various angles of the workpiece while fixing it without hindering it.

[0034] Reference Figure 1 、 Figure 3 and Figure 5 The positioning mechanism 2 includes two first gears 201, which are respectively fixedly connected to the bottom of the inner wall of the corresponding L-shaped plate 8. A reserved hole 205 is opened on the outer side of the L-shaped plate 8. The inner side of the first gear 201 is slidably connected to a sliding rod 203. By rotating the sliding rod 203, the first gear 201 can be driven to rotate.

The outer side of the second gear 202 passes through the L-shaped plate 8 and is fixedly connected to the rotating cover 9.

[0035] Specifically, by turning the knob 204, the second gear 202 can be driven to rotate, and the first gear 201 can be driven to rotate through meshing transmission. As the first gear 201 is engaged with the cross-shaped sliding rod 203, the sliding rod 203 can be driven to rotate at the same time as the first gear 201. At the same time, the rotation of the sliding rod 203 can simultaneously drive the two first gears 201 and the second gear 202 to rotate. As the second gear 202 rotates, the rotating cover 9 can be driven to rotate, so as to turn the workpiece stably and synchronously to prevent damage to the workpiece due to asynchrony.

[0036] Reference Figure 3 、 Figure 4 and Figure 5 , a mounting cover 14 is fixedly connected to the middle part of the inner side of the positioning cover 1, and a reserved groove 15 is opened on the top of the mounting cover 14, through which the first bevel gear 4 and the second bevel gear 7 can be protected; a screw 13 is provided on the outside of the rotating cover 9, and the screw 13 is threadedly connected to the clamping plate 11, and the screw 13 can improve the firmness of the workpiece; the outer wall of the positioning cover 1 is fixedly connected with a handle 16 on all sides, and the outer side of the handle 16 is fixedly connected with a sheath 17, which can facilitate holding and carrying the device;

[0037] Specifically, the installation cover 14 can prevent the first bevel gear 4 and the second bevel gear 7 from external impurities affecting their meshing transmission, and the reserved groove 15 thereon can prevent them from interfering with the rotation of the sliding rod 203. By rotating the screw 13, the stability and firmness of the splint 11 to the screw 13 during movement can be improved. The handle 16 can facilitate holding and carrying the device, and the sheath 17 can improve the comfort of holding.

[0038] Reference Figure 1 、 Figure 3 and Figure 4 , the bottom of the positioning cover 1 is fixedly connected with positioning blocks 18 on all sides, and positioning holes 19 are opened on the outer side of the positioning blocks 18 to improve the firmness of the device when it is fixed; the front and rear sides of the inner wall of the positioning cover 1 are provided with sliding grooves 20, and the outer side of the L-shaped plate 8 is slidably connected to the sliding grooves 20, which can improve the stability of the L-shaped plate 8 when it moves; the middle part of the front side of the positioning cover 1 is fixedly connected with a controller 12, and the controller 12 is electrically connected to the motor 3, and the motor 3 can be controlled by the controller 12;

[0039] Specifically, by installing a screw member in the positioning hole 19 on the positioning block 18, the device can be easily installed and fixed. The slide groove 20 can improve the stability of the L-shaped plate 8 during movement, and the controller 12 can control the start and operation of the motor 3.

[0040] Working principle: Before using the device, first start the motor 3, the motor 3 starts to run and drives the first bevel gear 4 to rotate. Due to the meshing transmission relationship between the first bevel gear 4 and the second bevel gear 7, the rotation of the first bevel gear 4 will prompt the second bevel gear 7 to rotate accordingly. When the second bevel gear 7 rotates, it will drive the bidirectional threaded rod 5 to rotate together. During the rotation of the bidirectional threaded rod 5, the moving rod 6 will move through the threaded connection between it and the moving rod 6, thereby driving the L-shaped plate 8 to move left and right, thereby adjusting the position of the L-shaped plate 8. At this time, the electric telescopic rod 10 is started, and the electric telescopic rod 10 will play its function to drive the splint 11 to move, so that the splint 11 can effectively fix the workpiece, ensuring the stability of the workpiece during the detection process. At the same time, through the rotation of the rotating cover 9, the workpiece can be flexibly adjusted to turn over. In this way, after the workpiece is fixed, it is still possible to conveniently detect various angles of the workpiece, which provides convenient conditions for comprehensive and accurate detection of the workpiece, ensuring the smooth progress of the detection work and the reliability of the detection results;

[0041] By turning the knob 204, the rotation of the knob 204 can drive the second gear 202 to rotate. Since there is a meshing transmission relationship between the second gear 202 and the first gear 201, the rotation of the second gear 202 will drive the first gear 201 to rotate through the meshing action. At this time, as the first gear 201 is engaged with the cross-shaped sliding rod 203, the first gear 201 can simultaneously drive the sliding rod 203 to rotate, and the rotation of the sliding rod 203 will simultaneously drive the two first gears 201 and the second gear 202 to rotate. As the second gear 202 continues to rotate, it can eventually drive the rotating cover 9 to rotate. Such a design can turn the workpiece in a stable and synchronous manner, effectively preventing damage to the workpiece due to asynchrony during the turning process, ensuring the safety and stability of the workpiece during the turning process, and providing reliable protection for subsequent processing or testing operations.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
