[0037] The clamping assembly 2 comprises two clamping blocks 21, the two clamping blocks 21 are slidingly installed in the clamping groove 12, and the clamping blocks 21 are connected with a driving assembly.

[0038] The thickness of the clamping block 21 is the same as the width of the pad 16. The top of the clamping block 21 is provided with a limiting groove 22.

[0039] The driving assembly comprises a cylinder 23 fixedly installed on the top surface of the base 11, the piston rod of the cylinder 23 extends through the top of the base 11 into the clamping groove 12, and the end of the piston rod of the cylinder 23 is fixedly installed with a clamping plate 24 inserted into the clamping groove 12.

[0040] The end surface of the cylinder body of the cylinder 23 is welded with a fixing frame 25 for fixing the clamp and the experimental device, and the experimental device is a known tensile testing machine.

[0041] The cylinder 23 is controlled to work, and the clamping block 21 can be driven to move in the vertical direction by the clamping plate 24.

[0042] The limiting assembly 3 comprises a pressing plate 31 for preventing the clamping block 21 and the replacement plate from being separated from the chuck seat 1, and the outer side of the pressing plate 31 is provided with a position adjusting assembly for controlling the horizontal position of the pressing plate 31.

[0043] The rear side surface of the pressing plate 31 abuts against the front side surface of the clamping block 21 and the backing plate 16.

[0044] The upper and lower sides of the pressing plate 31 are provided with guide blocks 32 inserted into the pressing plate grooves 14 and capable of moving along the axis of the pressing plate grooves 14.

[0045] The pressing plate 31 and the guide blocks 32 are integrally formed of metal materials. The pressing plate grooves 14 can limit the movement direction of the pressing plate 31.

[0046] The position adjusting assembly comprises a guide bolt 33 slidingly installed in the guide groove 15, and the end of the guide bolt 33 is threadedly connected with the pressing plate 31.

[0047] The guide bolt 33 can limit the movement distance of the pressing plate 31, and cooperates with the pressing plate grooves 14 to prevent the pressing plate 31 from being separated from the base 11.

[0048] The middle part of the guide bolt 33 and the guide groove 15 are sleeved with an elastic member 34.

[0049] The elastic member 34 is a spiral spring, and the end surfaces of the elastic member 34 abut against the end of the guide bolt 33 and the bottom surface of the guide groove 15, respectively.

[0050] The elastic force of the elastic member 34 can drive the pressing plate 31 to move away from the clamping block 21.

[0052] The positioning plane 36 is opposite to the rotating shaft of the eccentric handle 35 and is symmetric to the center of the eccentric handle 35.

[0053] Under the elastic force of the elastic member 34, the outer side surface of the pressing plate 31 abuts against the outer side surface of the eccentric handle 35. By rotating the eccentric handle 35, the pressing plate 31 can be driven to move, and by controlling the rotating angle of the eccentric handle 35, the position of the pressing plate 31 can be controlled.

[0054] When the positioning plane 36 abuts against the pressing plate 31, the pressing plate 31 simultaneously presses the clamping block 21 and the gasket 16 on the outer side. At the same time, the pressing plate 31 abuts against the positioning plane 36, which can prevent the eccentric handle 35 from being accidentally rotated in the process.

[0055] Working principle:

[0056] By rotating the eccentric handle 35, the elastic force of the elastic member 34 is utilized to drive the pressing plate 31 to move outward, so that the clamping groove 12 and the clamping groove 13 are completely exposed.

[0057] The clamping block 17 is aligned with the clamping groove 13 and is inserted, then the clamping block 21 is placed into the clamping groove 12, and the clamping plate 24 is clamped with the limiting groove 22.

[0058] Then the eccentric handle 35 is rotated to drive the pressing plate 31 to move towards the clamping block 17 until the positioning plane 36 abuts against the pressing plate 31.

[0059] In the experiment process, the pressing plate 31 abuts against the positioning plane 36, which can prevent the eccentric handle 35 from being accidentally rotated in the process.

[0060] The clamping block 17 abuts against the gasket 16, and the pressure is applied to the gasket 16 to avoid the deformation of the base 11. When the gasket 16 is deformed, a new gasket 16 can be replaced to ensure that the device can continue to be used and the maintenance time is reduced.

[0061] At the same time, the rotating angle of the eccentric handle 35 is controlled, which can individually press the gasket 16 to realize the individual replacement of the clamping block 17.

[0062] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the utility model and are not used to limit the utility model.
