[0021] The technical solution of the utility model is described in detail below in conjunction with specific implementation methods and the accompanying drawings of the specification.

[0022] like Figure 1 As shown, the flexible positioning fixture device for automated instrument assembly of the utility model comprises a tray bottom plate 1, a positioning bottom plate 4 is installed in the center of the upper surface of the tray bottom plate 1, and limit fixing seats 11 are symmetrically arranged at both ends of the upper surface of the positioning bottom plate 4. In this embodiment, the limit fixing seats 11 are fixed to the positioning bottom plate 4 by screws.

[0023] A centering clamping block 8 is symmetrically arranged between the two limiting fixed seats 11. The centering clamping block 8 is installed on the upper surface of the positioning base plate 4 through a linear guide rail 6. The centering clamping block 8 can move along the linear guide rail 6 to clamp instruments of different diameters, and the movement of the centering clamping block 8 is limited by the limiting fixed seat 11. In this embodiment, the centering clamping block 8 adopts a V-shaped centering clamping block. The setting of the V-shaped groove makes the self-centering structure of the circle more accurate during centering clamping, and it is easier to clamp and position. The V-shaped groove forms a better positioning effect of the action force and reaction force formed by the screw and the tension spring. The grooves on both sides of the V-shaped groove are used to avoid interference from different instruments; it can also be designed into other shapes as long as the positioning function can be realized. The centering clamping block 8 can be stretched or cut into a corresponding shape according to the shape of the instrument, and after cooperating with the quick-change base, it can realize the positioning function of all instruments of similar structure. A card slot is provided on the bottom surface of the centering clamping block 8, and the card slot cooperates with the linear guide rail 6 to improve the positioning accuracy of the overall mechanism.

[0024] Adjusting screws 10 are symmetrically arranged on both sides of the centering clamping block 8, and tension springs 7 are connected between the adjusting screws 10 and the ends of the limit fixing seat 11. The centering clamping block 8 is fixed at a preset clamping position by the reaction force of the adjusting screws 10 and the tension spring 7, ensuring the flexible positioning of the centering clamping block 8, and realizing centering clamping through the linear guide rail 6. The installation position of the adjusting screw 10 is determined according to actual needs.

[0025] A pair of quick-change bases 12 are symmetrically arranged on the positioning base plate 4, and the quick-change bases 12 and the limit fixing bases 11 are arranged in a cross. The quick-change bases 12 are matched with the instrument, that is, different quick-change bases 12 are provided on the positioning base plate 4 according to different product types. The quick-change bases 12 can be designed according to the height and shape of different products to achieve the purpose of quick change, and finally the installation plane of each instrument is kept in a horizontal plane. The quick-change base 12 realizes quick plug-in and quick pull type change through the positioning pins set on the positioning base plate 4. Different quick-change bases 12 can be set according to different instrument products and the clamping distance of the centering clamping block 8 can be adjusted to achieve positioning compatibility of various instrument products.

[0026] The positioning base plate 4 is assembled by installing the tooling and fixed on the tray base plate 1 with screws. A linear guide 6 is provided between the centering clamping block 8 and the positioning base plate 4 to achieve clamping, thereby positioning the instrument. A tension spring 7 is provided between the centering clamping block 8 and the fixing seat 11, and the initial centering clamping size is adjusted by adjusting the screw 10. When strong positioning is required, the V-shaped centering block 8 is clamped.

[0027] A bottom pad 5 is arranged between the two centering clamping blocks 8. The bottom pad 5 can be quickly replaced on the tray bottom plate 1 through the positioning pin, so as to avoid the interference problem of different instrument bottom plates. A stop block 9 is installed on the top surface of the bottom pad 5 to prevent the steel ball from being stopped after the slider moves beyond the guide rail due to empty clamping or manual misoperation. The bottom pad 5 can also be omitted and set according to actual needs.

[0028] The tooling base plate 2 is installed on the upper surface of the pallet base plate 1. In this embodiment, the tooling base plate 2 is installed on the pallet base plate 1 through the tooling positioning handle 3, and the tooling positioning handle 3 is quickly inserted into the pin hole on the pallet base plate 1 to achieve consistency in multiple installations and consistency in rapid assembly of different tools.

[0029] After the centering clamping block 8 positions the instrument, since the clamping cylinder is provided on the line body corresponding to the installation station, the centering clamping block 8 can be tightened to achieve the clamping of the instrument. When the assembly requires strong positioning, the clamping cylinder is clamped. After the centering clamping block 8 is clamped, the gap between it and the instrument is eliminated, and the strong positioning effect is achieved under the action of the clamping force.

[0030] When it is necessary to take out or put in the instrument product, it is only necessary to set the distance between the V-shaped centering clamping block and the fixing seat by setting the adjustment screw to ensure that the gap between the fixture and the product can be taken and put in freely. When it is necessary to put it in, it is only necessary to judge the direction of the large and small heads of the product and directly put it into the tooling to automatically find the center of the circle and position it. When it is necessary to take out the product, if there is a centering clamping cylinder, first loosen the centering clamping cylinder so that the original preset gap between the V-shaped centering clamping block 8 and the product is retained, and the robot can easily take out the instrument in the tooling. Only by adjusting the adjustment screw 10 and replacing the quick-change base 12 can the precise positioning function of different instruments be realized, and the automated assembly work of the assembly line can be realized.

[0031] The distance between the centering clamping block 8 and the limiting fixing seat 11 can also be adjusted steplessly by screws, which is compatible with instruments of different diameters, and the initial clamping interval adjustment can be freely set to adapt to the assembly interval requirements required for assembly line assembly.
