The connecting piece 31 is located on one side of the sliding piece 21 opposite to the pushing piece 22, and the connecting piece 31 can push the sliding piece 21 to move when rotating, so that the pushing piece 22 pushes the workpiece.

The fastening member 40 has a substantially cylindrical shape, the fastening member 40 is used to connect the pressing member 32 and the positioning plate 11, and the fastening member 40 is moved to adjust the distance between the pressing member 32 and the positioning plate 11, thereby pressing the pressing member 32 against the workpiece.

The working process of the embodiment of the application is as follows: a workpiece is placed on the positioning plate 11, the movable fastener 40 adjusts the distance between the pressing piece 32 and the positioning plate 11, so that the pressing piece 32 presses the workpiece to the positioning plate 11, the pressing piece 32 drives the rotating piece 31 to move, the connecting piece 31 rotates to push the sliding piece 21 to move, and the pushing piece 22 pushes the workpiece to fix the workpiece on the positioning plate 11.

The fastener 40 further includes a pressing head 41, the pressing head 41 is substantially cylindrical, and the pressing head 41 is disposed at an end of the fastener 40 adjacent to the pressing member 32 and presses against the pressing head 41 to adjust the distance between the pressing member 32 and the positioning plate 11.

In some embodiments, the clamping fixture 100 further includes a base 60, and the base 60 is connected to the positioning plate 11 and is used for bearing the positioning assembly 10, the pushing block assembly 20, the pressing plate assembly 30 and the fastener 40, so as to prevent the clamping fixture 100 from moving after clamping a workpiece, thereby affecting the detection result of the testing device 50.

In an embodiment, the positioning assembly 10 further includes at least one first elastic member 12, one end of the first elastic member 12 is connected to a side of the sliding slot away from the connecting member 31, and the other end of the first elastic member 12 is connected to the sliding member 21. When the moving fastener 40 reduces the distance between the pressing member 32 and the positioning plate 11, the pressing member 32 drives the sliding member 21 to move through the connecting member 31, so that the pushing member 22 pushes the workpiece, and the first elastic member 12 is in a compressed state. When the moving fastener 40 increases the distance between the pressing member 32 and the positioning plate 11, the first elastic member 12 provides an elastic force to restore the slider 21.

Referring to fig. 5, a groove 14 for placing the workpiece is formed in the positioning plate 11 adjacent to the pushing member 22, and the surface height of the groove 14 is lower than the surface height of the positioning plate 11, so that the pressing member 11 presses the workpiece into the groove 14, thereby fixing the workpiece.

The positioning plate 11 is provided with a baffle 15 at a position adjacent to the pushing member 22, the baffle 15 is substantially sheet-shaped, and when the pressing member 11 presses the workpiece into the groove 14, the sliding member 21 drives the pushing member 22 to move, so that the pushing member 22 pushes the workpiece to the baffle 15, and the workpiece is further stably fixed, so that the testing device 50 detects the workpiece.

The working process of the embodiment of the application is as follows: the workpiece is placed in the groove 14, the pressing head 41 is pressed to adjust the distance between the pressing piece 32 and the positioning plate, the second elastic piece 13 is compressed to enable the pressing piece 32 to press the workpiece, meanwhile, the connecting piece 31 drives the pressing portion 311 to move, the first elastic piece 12 is compressed to enable the sliding piece 21 to drive the pushing piece 22 to move, the workpiece is pressed against the baffle plate 14, the pushing piece 22 compresses the third elastic piece 211 to prevent the workpiece from being scratched, and the testing equipment 50 detects the clamped workpiece. After the test is completed, the ram 41 is moved to adjust the distance between the pressing member 32 and the positioning plate 11, the first elastic member 12 resets the sliding member, and the second elastic member 13 resets the pressing member 32.

The clamping fixture 100 moves the fastener 40 to adjust the distance between the pressing member 32 and the positioning plate 11, so that the pressing member 32 presses the workpiece, and the pressing member 32 drives the connecting member 31 to rotate to push against the sliding member 21, so that the pushing member 22 pushes against the workpiece, thereby completely positioning the workpiece and ensuring that the workpiece is clamped in place. The clamping jig is simple and convenient to operate, and the workpiece is clamped through the pressing piece 32 and the pushing piece 22, so that the clamping stability and the working efficiency of the clamping jig 100 are improved.
