[0002] The measurement of wire length plays a vital role in fields such as power engineering, wire and cable manufacturing, and household appliance installation. Traditional methods for measuring wire length mainly include using manual tools such as tape measures, steel tape measures, or measuring ropes.

[0003] The utility model patent with the authorization announcement number CN210089552U discloses "A test sampling and length measuring device and its control system", which includes a pay-off shaft, a take-up shaft, a meter wheel and a pressure wheel; the two ends of the wire to be measured are respectively wound on the pay-off shaft and the take-up shaft; the pressure wheel and the meter wheel are located on the same vertical line and are arranged between the pay-off shaft and the take-up shaft; the wire passes between the pressure wheel and the meter wheel, and the movement of the wire causes the pressure wheel and the meter wheel to rotate. This solves the problem that when sampling and measuring the length of existing wires, the length can only be obtained by placing the wire on a plane such as the ground and then measuring the length of the wire with a tape measure. However, in this way, if there is no external force on the wire, the measured length is inaccurate, and the wire structure is easily damaged due to changes in state during the measurement process.

[0004] However, the above-mentioned prior art solutions still have the following deficiencies: after long-term use, when the pressure wheel or the meter wheel is worn, causing slippage between the wire and the meter wheel, it will affect the measured length and cause errors. Utility Model Content

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0007] A wire length measuring device comprises a workbench, the top of the workbench is fixedly connected to a guide plate, one side of the guide plate is provided with a through hole, the top of the workbench is fixedly connected to a vertical plate, the front of the vertical plate is fixedly connected to a horizontal plate, the top of the horizontal plate is fixedly connected to a rack, the front of the guide plate is fixedly connected to two groups of support plates, each group of support plates is fixedly connected to a sliding rod, the surfaces of the sliding rods are slidably sleeved with sliders, the ends of the sliders close to each other are fixedly connected to the same mounting frame, a servo motor is fixedly connected in the mounting frame, the output shaft of the servo motor is fixedly connected to a gear, and the front of the mounting frame is fixedly connected to a clamping assembly.

[0008] Preferably, the clamping assembly comprises a clamping frame, and two electric cylinders are fixedly connected to the front side of the clamping frame, and clamping plates are fixedly connected to the ends of the two electric cylinders close to each other.

[0009] Preferably, the clamping frame is in a U-shaped shape, and the two electric cylinders are symmetrically arranged up and down.

[0010] Preferably, the gear is meshed with the rack, and the mounting frame is in a U-shaped shape.

[0013] Preferably, four legs are fixedly connected to the bottom of the workbench, and self-locking universal wheels are respectively fixedly connected to the bottoms of the four legs.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] First, pass the wire to the right through the through hole of the guide plate, so that the wire is passed through the two clamping plates, and the clamping plates are pushed by the electric cylinder to clamp the wire. The servo motor drives the gear to rotate, so that the gear moves along the rack, and the sliders slide on the slide rods respectively, thereby moving the clamped wire to the right. After moving to the required position, the electric cylinder releases the clamping of the cable, and then the servo motor drives the gear to reset along the rack. After resetting, repeat the above operation again, and measure the length of the wire pulled to the right. Each reset is counted once, and the length of the wire can be calculated by multiplying the total number of resets by the length of the pull, thereby avoiding the problem of slippage between the wire and the meter wheel affecting the measured length and causing errors, and the length of the wire is measured accurately.

[0016] Second, by setting the ball in the wire inlet tube, when the wire is passed through the wire inlet tube and pulled to the right, the setting of the ball can reduce the friction of the wire and protect the surface of the wire. The self-locking universal wheel set at the bottom of the leg can facilitate the movement and fixation of the device. BRIEF DESCRIPTION OF THE DRAWINGS
