Description

Technical Field

[0001] This utility model belongs to the technical field of cable termination equipment, and specifically relates to a termination equipment clamping mechanism. Background Technology

[0002] The clamping mechanism of the termination equipment is generally used to clamp the cable inside the conductor holder. Because the cable is usually pulled out from the roll, it needs to be cut and stripped to expose the wire, and then the end of the wire is terminated. Termination can be done by adding a terminal ring or soldering. After termination, the cable with the termination needs to be pulled out a certain distance by a cable pulling device before cutting. This realizes fully automated fixed-distance termination of the cable. When the existing cable passes through the conductor holder, it is generally clamped by a pneumatic or electric suction mechanism. When the cable needs to be pulled, it is released. The conductor holder is generally small in size, and sometimes the conductor holder needs to be turned when termination is performed. Setting pneumatic clamps and electric suction clamps on the conductor holder will increase the cost. In view of this, this solution was developed. Utility Model Content

Detailed Implementation

[0022] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0023] like Figures 1-5 As shown, this embodiment provides a clamping mechanism for a terminal cutting device, including a drive assembly 4, a wire seat 1, a rotating assembly 2, and a stamping assembly 3.

[0024] The wire seat 1 is located at the rotating end of the rotating assembly 2. Specifically, the rotating assembly 2 includes a rotating table 21, and a drive motor is installed inside the rotating table 21. The output end of the drive motor is fixedly connected to the lower surface of the base 11.

[0025] Preferably, a drive assembly 4 is also provided below the rotating assembly 2. The front and rear drive assembly 4 is used to drive the rotating table 21 to move back and forth. The drive assembly 4 includes a movable seat, a guide rail and a drive body. The movable seat is fixedly connected to the lower surface of the rotating assembly 2. The lower surface of the movable seat is provided with a sliding groove, which is adapted to the guide rail. The drive body is used to drive the movable seat to move. The drive body is a drive cylinder. In this solution, a cylinder is used. Other structures that can achieve front and rear movement in the prior art can also be used.

[0026] The conductor holder 1 includes a base 11, a bottom plate 13, an upper plate 12, multiple deformable conductor tubes 15, and a conductor plate. The bottom plate 13 is disposed on the upper surface of the base 11, and at least two support columns 14 are formed on the bottom plate 13. The upper plate 12 has a through hole, through which the support columns 14 pass and have a retaining ring 141 at their upper ends. A return spring 142 is disposed on the circumference of the support column 14. Multiple first arc-shaped grooves are formed on the upper surface of the bottom plate 13, and multiple second arc-shaped grooves are formed on the lower surface of the upper plate 12. The multiple first arc-shaped grooves are respectively adapted to the multiple second arc-shaped grooves. The deformable conductor tubes 15 are fixedly disposed in the first arc-shaped grooves. In this design, there are five first arc-shaped grooves and five second arc-shaped grooves. Only three of them are used in the production process. The included angle between the two ends of the first arc-shaped grooves and the center of the circle is less than 180°, so as to ensure that the deformable conductor tubes 15 are deformed when pressed. A guide plate is also provided on the upper surface of the base 11. The guide plate is located on one side of the base plate 13. A guide hole is provided on the guide plate 16.

[0029] Working principle: As shown in the figure, the welding station 5 and the wire stripping and pulling station 6 are respectively set on both sides of the wire seat 1. The cable passes through the deformable wire cylinder 15 of the wire seat 1. The punching head presses the upper plate 12, so that the upper plate 12 and the bottom plate 13 move closer to each other, causing the deformable wire cylinder 15 to deform and clamp the cable. Then the cable is stripped towards the wire stripping and pulling station 6. Then the rotating table 21 rotates, and the cable enters the welding station 5 for welding terminals. After welding is completed, the rotating table 21 rotates back to the wire stripping and pulling station 6, and the pulling assembly clamps the cable and pulls it at a fixed distance. The pulling force of the pulling assembly can overcome the resistance of the deformable wire cylinder 15, so that the cable is pulled out and the deformable wire cylinder 15 returns to its original position.
