[0026] like Figure 1 and Figure 2 As shown, the electric locking mechanism proposed in the embodiment of the present invention is used to lock the measured object, and the electric locking mechanism includes a base 1, a clamping member, a rotatable member and an electric transmission assembly. The clamping member is installed on the base 1, and the clamping member includes a clamping member body 2 and a pressure arm 3 arranged on the clamping member body 2, and the measured object 4 is installed between the pressure arm 3 and the clamping member body 2. The rotatable member is installed on the base 1, and the rotatable member is in contact with the pressure arm 3. The electric transmission assembly is installed on the base 1 and in contact with the rotatable member, and the rotatable member is driven to rotate by the electric transmission assembly, and the pressure arm is driven to clamp the measured object by the rotation of the rotatable member. In this way, the rotatable member is directly driven to rotate by the electric transmission assembly, and when the rotatable member rotates, the pressure arm is driven to clamp the measured object, thereby locking the measured object. Compared with the prior art of manually fixing the measured object, the operation is convenient, thereby improving the installation efficiency of the measured object.

[0027] In this embodiment, the electric transmission assembly includes a mounting seat, a motor 5, a retractable rotating assembly and a screw 6, and the mounting seat is fixed to the base 1 by screws. In this embodiment, the mounting seat is concave-shaped, and the mounting seat includes a vertical plate 7, a first horizontal plate 8 provided on the upper side of the vertical plate 7, and a second horizontal plate 9 provided on the lower side of the vertical plate 7, and the vertical plate 7 is fixed to the side of the base 1 by screws.

[0028] The motor 5 is fixed to the second horizontal plate 9 of the mounting seat by screws, and the rotating shaft 10 of the motor 5 is connected to the retractable rotating assembly. A screw nut 11 is provided on the first horizontal plate 8 of the mounting seat, and the screw 6 cooperates with the screw nut 11, and the lower end of the screw 6 is fixedly connected to the retractable rotating assembly, and the upper end of the screw 6 is in contact with the rotatable part. The motor 5 drives the retractable rotating assembly to rotate, and the rotation of the retractable rotating assembly drives the screw 6 to rotate, thereby causing the screw 6 to move up and down, thereby driving the rotatable part to rotate, and when the rotatable part rotates, it drives the pressure arm 3 to clamp the measured part 4. The coordinated transmission of the screw 6 and the screw nut 11 ensures that the operation of the mechanism is stable and reliable.

[0029] In this embodiment, the retractable rotating assembly includes a rotating block 12, a transmission pin 13 and a chuck 14. The rotating shaft 10 of the motor 5 is connected to the middle of the rotating block 12. An opening 15 is provided at one end of the rotating block 12. The lower end of the screw rod 6 is fixedly connected to the chuck 14. The upper end of the screw rod 6 contacts the rotatable member. The upper end of the transmission pin 13 is fixedly connected to one end of the chuck 14. The lower end of the transmission pin 13 extends into the opening 15, and the transmission pin 13 can move up and down in the opening 15. The motor 5 drives the rotating block 12 to rotate, and the rotation of the rotating block 12 drives the transmission pin 13 to rotate, thereby driving the chuck 14 and the screw rod 6 to rotate together. During the rotation process, due to the cooperation of the screw rod 6 and the screw nut 11, the transmission pin 13, the chuck 14 and the screw rod 6 will move up and down, thereby driving the rotatable member to rotate up and down.

[0030] like Figure 2 and Figure 3 As shown, in this embodiment, a notch 16 is provided on the base 1, and the rotatable part includes a connecting rod 17 and a clamping part. The clamping part is a straight rod 18. The connecting rod 17 is installed in the notch 16 of the base 1 through a rotating shaft 19. A mounting hole 20 is provided on the connecting rod 17. The straight rod 18 is installed in the mounting hole 20 of the connecting rod 17, and the end of one end of the straight rod 18 is in contact with the pressure arm 3. One end of the connecting rod 17 is a contact end 21, and the other end of the connecting rod 17 is a free end. The upper end of the screw rod 6 is in contact with the contact end 21 of the connecting rod 17.

[0031] In this embodiment, the straight rod 18 is located on the connecting rod 17 between the contact end 21 and the rotating shaft 19, forming a lever-type structure for easy rotation.

[0032] like Figure 1 and Figure 3As shown, the movement principle of the electric locking mechanism is: the tested piece 4 is inserted between the pressure arm 3 and the clamp body 2, at which time the pressure arm 3 is in a free state, and then the motor 5 is driven to rotate clockwise, thereby driving the rotating block 12, the transmission pin 13, the chuck 14 and the screw rod 6 to rotate clockwise. Due to the cooperation between the screw rod 6 and the screw nut 11, the screw rod 6 will move downward during the clockwise rotation, and the transmission pin 13 will also move downward in the opening. As the screw rod 6 moves downward, it drives the connecting rod 17 and the straight rod 18 to rotate clockwise (refer to Figure 3 , the connecting rod and the straight rod will rotate clockwise due to gravity), so that the straight rod 18 will press the pressure arm 3 downward, and the pressure arm 3 is in a downward pressure state, thereby clamping the test piece 4. The drive motor 5 rotates counterclockwise, thereby driving the rotating block 12, the transmission pin 13, the chuck 14 and the screw rod 6 to rotate counterclockwise. Due to the cooperation of the screw rod 6 and the screw nut 11, the screw rod 6 will move upward during the counterclockwise rotation, and the transmission pin 13 will also move upward in the opening. As the screw rod 6 moves upward, it drives the connecting rod 17 and the straight rod 18 to rotate counterclockwise (refer to Figure 3 , the connecting rod and the straight rod will be lifted up and rotate counterclockwise), and since the force of the straight rod 18 acting on the pressing arm 3 disappears, the pressing arm 3 will recover upward to be in a free state, thereby releasing the measured object 4.

[0033] like Figure 2 As shown, in this embodiment, a spherical body 22 is provided at the upper end of the screw rod 6 , and the spherical body 22 is in contact with the connecting rod 17 .

[0034] like Figure 2 and Figure 4 As shown, a baffle 23 is provided at the other end of the rotating block 12, and two photoelectric switches are provided on the mounting seat. The two photoelectric switches are mounted on a circuit board 26, and the circuit board 26 is fixed on the first horizontal plate 8 of the mounting seat. The two photoelectric switches are a first photoelectric switch 24 and a second photoelectric switch 25. The first photoelectric switch 24 and the second photoelectric switch 25 are arranged at a certain angle on the circumference. In this embodiment, the angle is 90 degrees, and the baffle 23 can rotate between the first photoelectric switch 24 and the second photoelectric switch 25. The two photoelectric switches are used to control the rotation angle of the motor, thereby controlling the height of the screw rod moving up and down, thereby ensuring accuracy.

[0035] In the non-working state, the pressure arm is in a free state, and the baffle is at the position of the first photoelectric switch. When the tested piece is inserted between the clamp body and the pressure arm, the motor rotates to move the baffle to the position of the second photoelectric switch. At this time, the screw moves downward, so that the straight rod presses the pressure arm down, and the pressure arm clamps the tested piece. After the test is completed, the motor rotates to rotate the baffle from the position of the second photoelectric switch to the position of the first photoelectric switch. At this time, the screw moves upward, so that the pressure arm returns to a free state and releases the tested piece.

[0036] like Figure 5As shown, there is a through hole 27 between the clamp body 2 and the pressure arm 3, and the straight rod is inserted into the through hole 27.

A person skilled in the art may implement the present invention in a variety of variations without departing from the scope and essence of the present invention. For example, a feature shown or described as part of one embodiment may be used in another embodiment to obtain another embodiment.
