Description

A cable bending test machine

technical field

The utility model relates to the technical field of cable production, in particular to a cable bending test machine.

Background technique

At present, the bending test of existing coaxial cables, especially flexible cables, generally uses a relatively simple bending test device, as shown in Figure 1. This bending test device fixes the two ends of the cable on a fixed end and a On the rotating shaft, the rotating shaft rotates circularly around the axis to drive the cable to perform the bending test. This test device can only be tested with a set and fixed bending frequency and bending radius. The cable bending frequency and bending radius cannot be adjusted during the test. , so the existing test equipment has poor versatility and a low degree of automation of the bending test.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a cable bending testing machine with high efficiency, good test consistency and high degree of automation.

The technical solution adopted by the utility model to achieve the above technical purpose is: a cable bending test machine, which includes a frame, a guide rod and a rotating gear are arranged on the frame, and a guide rod is provided on the guide rod There is a fixing fixture for fixing one end of the cable, a swing rod for fixing the other end of the cable is provided on the rotating gear, a clamp for fixing the cable is provided at the end of the swing rod, and a transmission rack bar is engaged with the rotating gear. The transmission rack rod is installed in two guide linear bearing seats, the lower end of the transmission rack rod is connected with a swing link, and the swing link is connected with an angle adjustment rod, and the side of the angle adjustment rod is set There is a counting sensor, and the angle adjusting rod is arranged on a driving motor, and the driving motor is connected with a controller including a governor and a counter.

The swing connecting rod is provided with an adjusting screw capable of adjusting the length of the connecting rod; by changing the length of the connecting rod in the swing connecting rod, the stroke range of the reciprocating motion of the transmission rack bar can be changed, thereby changing the swing angle of the swing rod on the rotating gear .

The speed adjustment range of the driving motor is 0.28~1.05 r/s.

When the utility model is in use, start the motor, and the motor drives the angle adjustment rod and the swing connecting rod to rotate. When the swing connecting rod rotates, it drives the drive rack bar to reciprocate up and down, and when the drive rack bar moves up and down to reciprocate, it drives the swing bar on the rotating gear. Perform left and right swings, and the motor rotates the swing rod once to perform a reciprocating swing to complete a cycle test. By adjusting the length of the swing connecting rod adjusting screw, the stroke of the transmission rack bar reciprocating up and down can be adjusted, thereby changing the swing angle of the swing rod on the rotating gear, and the swing angle adjustment range of the swing rod is between 30 degrees and 90 degrees.

The counter in the controller can set the number of bending tests. The setting range is 1~9999*100 times. The counting sensor installed on the side of the angle adjustment rod will send a counting signal to the counter. When the number value set by the counting signal is reached , the controller cuts off the power supply of the driving motor to complete the test shutdown. The driving motor is a variable frequency speed regulating motor, and the rotation speed of the driving motor is adjusted through the governor to achieve the purpose of adjusting the bending speed.

The beneficial effects of the utility model are: adopting the above-mentioned structure, by setting the drive rack bar driven by the frequency conversion speed regulating motor, the angle adjustment rod and the swing connecting rod, the swing bar on the rotating gear is driven by the drive rack bar to swing, thereby driving The cable is subjected to a bending test. During the test, the cable bending frequency and bending radius can be adjusted conveniently. The test efficiency is high, the test consistency is good, and the degree of automation is high.
