[0041] like Figures 1 to 4 As shown, the fixture floating base of this embodiment includes a fixture bottom plate 1 and a first floating mechanism 2. The fixture bottom plate 1 is used to support the fixture body 100 at the bottom of the first direction. The fixture bottom plate 1 includes an upper bottom plate 11, a lower bottom plate 12 and a limiting rod 13. The upper bottom plate 11 is located above the lower bottom plate 12. The upper bottom plate 11 is provided with a limiting hole 111 and the lower bottom plate 12 is correspondingly provided with a limiting groove 121. The limiting rod 13 is penetrated through the limiting hole 111 and limited in the limiting groove 121. The cross section of the limiting hole 111 is larger than the cross section of the limiting rod 13, or the cross section of the limiting groove 121 is larger than the cross section of the limiting rod 13, or the cross section of the limiting hole 111 and the limiting groove 121 are both larger than the cross section of the limiting rod 13. The first floating mechanism 2 includes a mounting seat 21 and a floating spring 22. The mounting seat 21 is located below the fixture bottom plate 1 in the first direction. The floating spring 22 is installed between the fixture bottom plate 1 and the mounting seat 21.

[0042] The fixture floating base provided by the utility model uses a mounting seat 21 to mount the fixture bottom plate 1 on the working platform, and the fixture bottom plate 1 and the mounting seat 21 can float in the first direction through the floating spring 22. By setting the cross section of the limiting hole 111 to be larger than the cross section of the limiting rod 13, or the cross section of the limiting groove 121 to be larger than the cross section of the limiting rod 13, or the cross section of the limiting hole 111 and the limiting groove 121 to be larger than the cross section of the limiting rod 13, so that there is a gap between the limiting rod 13 and the inner wall of the limiting hole 111, or between the limiting rod 13 and the inner wall of the limiting groove 121, so that the upper bottom plate 11 and the lower bottom plate 12 can float in a small range of offset in a plane perpendicular to the first direction, so that the fixture body 100 can float in multiple directions relative to the working platform. When the workpiece placed on the fixture body 100 deviates from the theoretical position, the position of the workpiece is corrected by the floating base of the fixture floating in multiple directions, so that the fixed mechanism adapts to the floating of the fixture floating base, providing fast and accurate workpiece positioning and fixation, making the assembly process more efficient and improving the assembly effect and quality.

[0043] Exemplarily, the limiting rod 13, the limiting hole 111 and the limiting groove 121 are defined as the second floating mechanism, and the fixture base plate 1 may include multiple second floating mechanisms to enhance the structural strength and stability of the fixture base plate 1 when floating. Multiple second floating mechanisms are evenly arranged in the second direction, or multiple second floating mechanisms are evenly arranged in the third direction, wherein the first direction, the second direction and the third direction are perpendicular to each other. In this embodiment, the fixture base plate 1 includes four second floating mechanisms, and the four second floating mechanisms are arranged in a rectangular shape.

One bearing ring of the thrust bearing 14 is installed in the limit groove 121, and the other bearing ring is installed in the limit hole 111. When relative floating occurs between the upper base plate 11 and the lower base plate 12, the two bearing rings of the thrust bearing 14 float in an offset manner. The two bearing rings can apply the stress generated by the offset floating to the rolling element, thereby reducing the stress borne by the limit rod 13 and ensuring the service life of the limit rod 13.

[0045] like Figure 3As shown, a first mounting groove 211 is provided on the side of the mounting seat 21 facing the fixture bottom plate 1, and a second mounting groove 123 is correspondingly provided on the side of the lower bottom plate 12 facing the mounting seat 21.

[0048] Preferably, the first locking mechanism 4 further includes a first driving mechanism 43, which can drive the locking member 42 to move along the first direction. In this embodiment, the first driving mechanism 43 is a driving cylinder. In some other embodiments, the first driving mechanism 43 can be a driving motor, etc.

[0049] Furthermore, the fixture floating base also includes a second locking mechanism 5 , which is connected below the fixture bottom plate 1 and can limit the movement of the fixture bottom plate 1 in the first direction.

The fixture body 100 is installed above the fixture bottom plate 1 in a first direction, and the workpiece can be installed on the fixture body 100 .

[0051] The clamp assembly provided by the utility model sets the clamp body 100 on the above-mentioned clamp floating base. The clamp body 100 can float with the floating of the clamp floating base. Workers can complete assembly tasks more quickly, reduce production cycles and improve production capacity.

[0052] Specifically, the fixture body 100 includes a mounting plate 110, a fixture 120, a positioning assembly 130 and a detection element 140. The fixture 120, the positioning assembly 130 and the detection element 140 are installed on the mounting plate 110. The mounting plate 110 is connected to the fixture base plate 1. The fixture 120 is used to clamp the workpiece, the positioning assembly 130 is used to accurately position the workpiece on the fixture, and the detection element 140 can detect whether the workpiece is installed in place.

[0053] Furthermore, the positioning assembly 130 includes a first support platform 131, a second support platform 132, a first positioning seat 133 and a second positioning seat 134. The first support platform 131 and the second support platform 132 are respectively located on both sides of the fixture for supporting the workpiece in the first direction. The first positioning seat 133 and the second positioning seat 134 are respectively located on both sides of the fixture 120 for positioning the workpiece in the second direction and the third direction.
