In addition, if the terms "first", "second", etc. appear in the description of the present utility model, they are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0020] As shown in the accompanying drawings, the utility model comprises a lower seat body 1, an upper seat body 2 and a lateral floating adjustment device located between the lower seat body 1 and the upper seat body 2.

[0021] The top of the lower seat body 1 is symmetrically provided with a pair of sliding grooves 3 with one end of the outer side tilted downward, and the upper seat body 2 is a V-shaped structure.

[0022] The lateral floating adjustment device comprises two arc-shaped sliders 5 symmetrically distributed in the slide slot 3 and an adjustment screw 6 for adjusting the distance between the two arc-shaped sliders 5 .

[0023] During operation, the workpiece to be clamped is located on the upper seat body 2. When the upper seat body 2 is subjected to force, the vertical downward force of the upper seat body 2 and the vertical upward supporting force of the lower seat body 1 are converted into an extrusion force on the arc-shaped slider 5. The upper seat body 2 and the lower seat body 1 cooperate with the two arc-shaped sliders 5 to convert the extrusion force into lateral thrusts to the left and right sides. The two arc-shaped sliders 5 float in both directions, so that the tooling has an adaptive adjustment function and a high load-bearing capacity, so that the curved surface is subjected to balanced force during the support and clamping process.

[0024] The adjusting screw 6 is used to adjust the distance between the two arc-shaped sliders 5. The bottom side of the arc-shaped slider 5 is located in the slide groove 3, and the top side of the arc-shaped slider 5 contacts the bottom surface of the upper seat body 2. In this case, the bottom of the upper seat body 2 of the V-shaped structure is provided with a cut surface, that is, the bottom surface of the upper seat body 2 is an inverted trapezoidal structure, and the corresponding two slide grooves 3 are not connected. The plane at the top of the lower seat body 1 matches the cut surface at the bottom of the upper seat body 2. When the two arc-shaped sliders 5 move outward to a certain position, the upper seat body 2 contacts the lower seat body 1. Since two planes are in contact, they can remain stable.

[0025] When one side of the upper seat body 2 contacts the workpiece and the downward force increases, while the other side is subjected to less force, the mechanical balance is broken, and the arc-shaped slider 5 on the side subjected to less force continues to move forward to push the upper seat body 2 on one side upward until the mechanical balance is restored, completing the adaptive adjustment function.

[0026] Furthermore, limiting plates 7 are respectively provided on both sides of the lower seat body 1 , and inwardly bent end limiting bosses are respectively provided at both ends of the limiting plates 7 , and the upper seat body 2 is embedded in the two limiting plates 7 of the lower seat body 1 .

[0027] That is, the limit plate 7 is located in a U-shaped structure, and a slide groove structure is enclosed between the two limit plates 7 and the lower seat body 1. The upper seat body 2 is located in the slide groove, which plays a limiting role and generates position constraints on the upper seat body 2 to prevent the upper seat body 2 from sliding sideways and tipping over. The width and length of the slide groove structure must be greater than the corresponding width and length of the upper seat body 2, so that the upper seat body 2 can adaptively adjust its posture after being subjected to force.

[0028] Furthermore, corresponding screw avoidance grooves are respectively provided at the top of the lower seat body 1 and the bottom of the upper seat body 2, and the adjusting screw 6 is located in the grooves.

[0029] When the lower seat body 1 is in contact with the upper seat body 2, the adjusting screw 6 is located in the groove.

[0030] Furthermore, one of the two arc-shaped sliders 5 is provided with a threaded hole, and the other arc-shaped slider 5 is provided with a screw avoidance hole. The two arc-shaped sliders 5 are connected by an adjusting screw 6 and the spacing between them can be adjusted.

[0031] When in use, the distance between the two arc-shaped sliders 5 can be adjusted by simply rotating the adjusting screw 6 .

[0032] One end of the adjusting screw rod 6 is threaded with a locking nut 11. The locking nut 11 is a locking nut for preventing loosening. A spring washer is used to tighten the adjusted tooling to prevent the locking nut 11 from loosening during vibration.

[0033] The locking nut 11 is used to limit the maximum distance between the two arc-shaped sliders 5 .

[0034] Furthermore, a connecting seat 12 is provided at the bottom of the lower seat body 1, and connecting positioning holes are respectively provided at both ends of the connecting seat 12.

[0035] The connecting seat 12 is used to be connected to the operating table, and the connecting positioning hole is a long hole with an open end, which is convenient for fixing by a screw.

[0036] Furthermore, an oil baffle 15 is provided at the end of the chute 3 at the lower end, and the height of the oil baffle 15 is not higher than half the height of the arc-shaped slider 5. When in use, the chute 3 is filled with lubricating oil, and the filling height of the lubricating oil is not higher than the oil baffle 15. When the arc-shaped slider 5 is adjusted in the chute 3, the lubricating oil can be brought out, making the adjustment smoother, and the oil baffle 15 prevents the lubricating oil from flowing out.
