Detailed Embodiments

[0022] The following combines the attached Figures 1 to 4A detailed description of the present invention is provided.

[0023] An improved structure of a wire clamping device of the present invention includes a box body 1. A power block 2 is arranged inside the box body 1. The power block 2 is hinged with a first connecting arm 21 and a second connecting arm 22. The first connecting arm 21 is hinged with a first clamping arm 31, and the second connecting arm 22 is hinged with a second clamping arm 32. Limiting ports 41 are arranged on both sides of the box body 1, and a limiting block 3 matched with the limiting ports 41 is arranged inside the box body 1. Both the first clamping arm 31 and the second clamping arm 32 are hinged with the limiting block 3. It also includes a power device 5. The power device 5 is provided with a movable push rod 51, and the front end of the movable push rod 51 is fixedly connected with the power block 2. In the solution of the present invention, the power device 5 is a cylinder, and the inner angles at the hinged joints of the first connecting arm 21 and the first clamping arm 31, and the second connecting arm 22 and the second clamping arm 32 are less than 180° and greater than 120°. The working principle of the present invention is as follows:

[0024] ①. The cylinder provides power to push the power block 2, and the power block 2 continuously pushes the first connecting arm 21, the second connecting arm 22, the first clamping arm 31, the second clamping arm 32 and the limiting block 3 forward.

[0025] ②. After the limiting block 3 moves a certain distance, it is caught by the limiting port 41 and stops moving. Since the first clamping arm 31 and the second clamping arm 32 are hinged with the limiting block 3, the first clamping arm 31 and the second clamping arm 32 also stop moving forward.

[0026] ③. The power block 2 continues to push the first connecting arm 21 and the second connecting arm 22 forward. At this time, the positions where the first connecting arm 21 and the second connecting arm 22 are hinged with the first clamping arm 31 and the second clamping arm 32 are stressed and spread outwards. The hinged joints of the limiting block 3 with the first clamping arm 31 and the second clamping arm 32 are used as fulcrums, so that the front ends of the first clamping arm 31 and the second clamping arm 32 move closer inward to form a clip structure to clamp the wire.

[0027] ④. The cylinder retracts the push rod 51 to pull the power block 2, and the power block 2 pulls back the first connecting arm 21, the second connecting arm 22, the first clamping arm 31, the second clamping arm 32 and the limiting block 3.

[0028] ⑤. The positions where the first connecting arm 21 and the second connecting arm 22 are hinged with the first clamping arm 31 and the second clamping arm 32 contract under the influence of the tensile force, and the front ends of the first clamping arm 31 and the second clamping arm 32 separate to release the clamped wire, completing the wire releasing action.

[0029] The present invention improves the structure of the wire clamping device, and only one cylinder is needed to realize the lifting and clamping action. It has a simple structure, low manufacturing cost, and saves the space occupied by the wire clamping device in the terminal machine. Because only one cylinder is used, the wire clamping device will immediately clamp the wire after it is lowered, which is fast and efficient. At the same time, the prior art uses the precise coordination control required by the double cylinders, while the present invention uses a power device such as a cylinder, which is easier to control.

[0030] Specifically, the limit block 3 is provided with a protrusion 33 protruding outward, and the protrusion 33 cooperates with the limit opening 41. When the protrusion 33 is supported by the upper end of the limit opening 41, the limit block 3 stops moving, the front ends of the first clamping arm 31 and the second clamping arm 32 are opened to the maximum extent, and the rising action and wire releasing action of the wire clamping device are completed. By using the method of cooperating the protrusion 33 and the limit opening 41, the descending depth of the wire clamping device can be intuitively seen, and fillers can be added to the limit opening 41 to adjust the position where the limit block 3 stays, thereby adjusting the descending depth of the wire clamping device.

[0031] The limit block 3 is provided with a first slot 34, the power block 2 is provided with a second slot 23, and the first slot 34 and the second slot 23 are provided with a first spring 6; similarly, the first clamp arm 31 is provided with a third slot 36, the second clamp arm 32 is provided with a fourth slot 37, and a second spring 7 is provided between the third slot 36 and the fourth slot 37. The limit block 3 has a friction force with the box body 1 when moving up and down. Therefore, when the limit block 3 descends or rises, the timing of the closing or separation of the front ends of the first clamp arm 31 and the second clamp arm 32 is unstable. In order to improve the stability, the first spring 6 and the second spring 7 are both reset springs that assist in separating the front ends of the first clamp arm 31 and the second clamp arm 32. When the limit block 3 moves downward, the first spring 6 supports the power block 2 and the limit block 3 to prevent the limit block 3 from being affected by the friction force during the downward movement, causing the front ends of the first clamp arm 31 and the second clamp arm 32 to close in advance. When the protrusion 33 of the limit block 3 is pressed against the lower end of the limit opening 41, The first clamp arm 31 and the second clamp arm 32 begin to close to form a clamping action; when the power block 2 is pulled back, the first spring 6 provides elastic force to open the limit block 3 and the power block 2, and the second spring 7 provides elastic force to open the front ends of the first clamp arm 31 and the second clamp arm 32. Without pulling the limit block 3, the front ends of the first clamp arm 31 and the second clamp arm 32 are separated in advance to complete the wire release action. When the front ends of the first clamp arm 31 and the second clamp arm 32 are opened to the maximum extent, the limit block 3 will be affected by the pulling force of the power block 2 and move upward until the protrusion 33 is supported by the upper end of the limit opening 41, completing the rising action of the wire clamping device.

[0032] The box body 1 includes a fixed block 4, and a first baffle 42 and a second baffle 43 respectively fixed on opposite sides of the fixed block 4, and the first baffle 42 and the second baffle 43 form a clamping cavity.

[0033] The first baffle plate 42 and the second baffle plate 43 are both provided with a slide groove 44 that cooperates with the power block 2 and the limit block 3. The power block 2 and the limit block 3 can move up and down along the slide groove 44, and the wire clamping device has strong stability in descending and ascending.

[0034] In the improved structure for further improving stability, the fixed block 4 is in a U shape, and the fixed block 4 is fixedly connected to the power device 5, and the push rod 51 passes through the empty space in the middle of the fixed block 4 and is connected to the power block 2.

[0035] The first clamp arm 31 and the second clamp arm 32 are both Z-shaped, and the first clamp arm 31 and the second clamp arm 32 are mirror-symmetrical, and the front ends of the first clamp arm 31 and the second clamp arm 32 are closed to form a clamping structure. In this technical solution, the first clamp arm 31 and the second clamp arm 32 adopt a Z-shaped clamp arm with a strong toughness structure. The Z-shaped clamp arm is not easy to bend and be damaged during the process of the wire clamping device quickly clamping the wire, which affects the accuracy of grabbing the wire.

[0036] The front ends of the first clamping arm 31 and the second clamping arm 32 are in an inverted L shape that simulates the clamping action of a human arm, which can enhance the stability of wire clamping.

[0037] Biting clasps 35 are provided at the front ends of the first clamping arm 31 and the second clamping arm 32. When the first clamping arm 31 and the second clamping arm 32 close to grasp a wire, the biting clasps 35 can prevent the grasped wire from falling off.

[0038] The above content is only a preferred embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. The content of this specification should not be construed as a limitation to the present invention.
