During the testing process, the products need to be positioned and fixed by fixtures, and then cooperate with external testing tools for performance testing. For various product test fixtures that require high positioning accuracy and small allowable errors, compared with most of the current conventional positioning mechanisms that rely on positioning pins or bilateral synchronous positioning, the current way to position a product is mainly through positioning pins and positioning holes of the product. However, because the positioning holes of the products need to pass through the positioning pins, there will be a gap between the product and the positioning pins. The gap will cause the product to shake a lot and the positioning will be inaccurate. Or the product is positioned diagonally, that is, a push block with a notch is used to push the product to the reference edge at 45 degrees for positioning. This positioning method, because it pushes in two directions at the same time, will cause inaccurate product positioning and is not suitable for the positioning of long strip products. It can only be suitable for small square products. If a simple structure can be designed to enable the product to be independently positioned in the X and Y axis directions, and the Y direction is adapted to the self-guided positioning of the pressure plate, and a high-precision multi-directional product positioning structure that is convenient for personnel to pick up and place can be realized, the above problems can be solved.

[0014] like Figures 1 to 4 As shown, in this embodiment, the utility model includes a carrier plate 1, an X-axis positioning module 2 and a Y-axis positioning module 3. A product profiling groove 4 is provided in the middle of the carrier plate 1, and the product profiling groove 4 cooperates with the product 5. The carrier plate 1 is also provided with an X-axis positioning groove 6 and a Y-axis positioning groove 7. The X-axis positioning module 2 is connected to the X-axis positioning groove 6 through a plurality of first positioning pins 8, and the Y-axis positioning module 3 is connected to the Y-axis positioning groove 7 through a plurality of second positioning pins 9. The movable end of the X-axis positioning module 2 and the movable end of the Y-axis positioning module 3 respectively cooperate with the product 5 on the product profiling groove 4. It can be seen that the X-axis positioning module 2 opens the movable end to place the product 5 into the product profiling groove 4, and the X-axis positioning module 2 is loosened to realize the positioning of the product 5 in the X-axis direction. The product 5 is pushed to the Y-axis positioning edge through the Y-axis positioning module 3 to realize the positioning of the product 5 in the Y-axis direction. The X-axis and Y-axis positioning modules are independent of each other and do not interfere with each other, so that the positioning accuracy is higher.

[0015] like Figure 2 and Figure 3 As shown, in this embodiment, the X-axis positioning module 2 includes a push block base 21 and an X-axis push block 22. The lower end surface of the push block base 21 is connected to the X-axis positioning groove 6 through a plurality of the first positioning pins 8. The X-axis push block 22 is slidably matched with the push block base 21 through a plurality of bushings 23 and a plurality of guide shafts 24. A plurality of first floating springs 25 are also provided between the push block base 21 and the X-axis push block 22. The X-axis push block 22 is floatingly matched with the push block base 21 through a plurality of the first floating springs 25. It can be seen that by pushing the X-axis push block 22 to put the product 5 into the product profiling groove 4, after the X-axis push block 22 is released, the X-axis push block 22 presses the product 5 under the elastic force of the plurality of the first floating springs 25, so as to realize the positioning of the product 5 in the X-axis direction.

[0016] like Figure 2 and Figure 4As shown, in this embodiment, the Y-axis positioning module 3 includes a guide base plate 31 and a Y-axis push block 32. The guide base plate 31 is connected to the Y-axis positioning groove 7 through a plurality of second positioning pins 9. Both ends of the main body of the Y-axis push block 32 are provided with extension push posts 33. The guide base plate 31 is provided with a plurality of movable openings 34 adapted to the extension push posts 33. The extension push posts 33 at both ends of the main body of the Y-axis push block 32 are matched with the product 5 through the plurality of movable openings 34. A plurality of second floating springs 35 are provided between the Y-axis push block 32 and the guide base plate 31. The Y-axis push block 32 is matched with the guide base plate 31 through the plurality of second floating springs 35. It can be seen that when the X-axis positioning is completed, the Y-axis push block 32 is pushed, and the extension push posts 33 push the product 5 to the Y-axis positioning edge to achieve the positioning of the product 5 in the Y-axis direction. The Y-axis push block 32 is released, and the Y-axis push block 32 returns to its initial position under the action of the plurality of second floating springs 35.

[0017] like Figure 3 As shown, in this embodiment, an extension stopper 26 is provided at the upper end of the X-axis push block 22, and the extension stopper 26 cooperates with the lower end surface of the product 5. It can be seen that when the product 5 is placed in the product profiling groove 4, the extension stopper 26 cooperates with the lower end limit portion of the product 5, so that the X-axis push block 22 can accurately limit the product 5.

[0018] As shown in the figure, in this embodiment, both ends of the carrier plate 1 are provided with limit slots 10, and the limit slots 10 cooperate with the external transmission mechanism. It can be seen that the limit slots 10 cooperate with the external transmission mechanism to increase the efficiency of loading and unloading.

[0019] The working principle of the utility model is as follows: the X-axis push block 22 is manually pushed open, and the X-axis push block 22 moves a distance under the guidance of the plurality of the bushings 23 and the plurality of the guide shafts 24, and moves out of a certain space, and the product 5 is placed in the product profiling groove 4, so that the product 5 is fitted with the carrier plate 1, and then the X-axis push block 22 is released, and the X-axis push block 22 moves the product 5 to fit the X-axis positioning edge of the carrier plate 1 under the action of the plurality of the first floating springs 25, and the positioning in the X direction is completed at this time, and the Y-axis push block 32 is pushed to move in the product direction, and the plurality of extended push posts 33 on the Y-axis push block 32 move under the guidance of the guide base plate 31, overcome the resistance of the plurality of the second floating springs 35, until the product 5 is fitted, and under the moving action of the Y-axis push block 32, the product 5 is moved to fit the Y-axis positioning edge of the carrier plate 1, and the positioning in the Y direction is completed at this time.

[0020] Although the embodiments of the present invention are described with practical solutions, they do not constitute limitations on the meaning of the present invention. For those skilled in the art, it is obvious to modify the implementation scheme and combine it with other solutions based on this description.
