Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments, which are described herein for the purpose of illustration only and are not intended to limit the invention.

As shown in fig. 1 and fig. 2, the present invention comprises a base 1, a weight block 6, a motor power line 16 and a PLC; the fixing block 13 and the clamp 8 are fixedly arranged on the base 1; a first sensor 2, a second sensor 4, a third sensor 10 and a fourth sensor 12 are fixedly arranged on one side of the base 1 from front to back in sequence; the first telescopic pin 17, the second telescopic pin 18, the third telescopic pin 19 and the fourth telescopic pin 20 are respectively and fixedly arranged on the inner sides of the first sensor 2, the second sensor 4, the third sensor 10 and the fourth sensor 12; the first detector 3 is arranged opposite to the first sensor 2 and the second sensor 4; the second detector 11 is arranged opposite to the third sensor 10 and the fourth sensor 12; the clamp 8 comprises a hand wheel 9; the first sensor 2, the second sensor 4, the third sensor 10, the fourth sensor 12, the first telescopic pin 17, the second telescopic pin 18, the third telescopic pin 19, the fourth telescopic pin 20, the first detector 3, the second detector 11 and the motor power line 16 are respectively electrically connected with the PLC.

During specific operation, firstly, the sliding rail assembly is placed on the base 1, the front end of the lower sliding rail 7 is propped against the fixed block 13, and the hand wheel 9 of the clamp 8 is rotated to enable the lower sliding rail 7 to be clamped; then, 80 kg of weight block 6 is placed on the upper slide rail 5, and the worker connects the motor power supply line 16 with the motor 14, and then starts the detection process.

The PLC firstly forwards transmits a motor 16 according to a preset numerical value, the motor 14 drives a transmission shaft 15 to rotate, the upper sliding rail 5 moves towards the direction of the second sensor 4, meanwhile, the PLC drives the second telescopic pin 18 to rise, as shown in figure 3, when the upper sliding rail 5 moves to the position of the second telescopic pin 18, the upper sliding rail is blocked by the second telescopic pin 18 and cannot move continuously, the upper sliding rail is detected by the second sensor 4, the second sensor 4 sends a signal to the PLC, and the PLC still forwards transmits the motor 14 to finish the detection that the locked-rotor position stays for 2 seconds; after 2 seconds, the PLC controls the motor 14 to stop rotating and controls the second telescopic pin 18 to descend; and then the PLC controls the motor 14 to rotate reversely to enable the upper sliding rail 5 to move towards the direction of the third sensor 10, controls the third telescopic pin 19 to rise, and when the upper sliding rail 5 moves to the position of the third telescopic pin 19, the upper sliding rail is blocked by the third telescopic pin 19 and cannot move continuously, and meanwhile, the third sensor 10 detects the movement, the third sensor 10 sends a signal to the PLC, and the PLC still rotates the motor 14 reversely to finish the detection of the locked-rotor position staying for 2 seconds.

In the process, one movement process of the upper sliding rail 5 between the second sensor 4 and the third sensor 10 is 10% -90% of an adjusting stroke, and each movement stroke is blocked by the second telescopic pin 18 and the third telescopic pin 19 and stays at the locked-rotor position for 2 seconds. According to the detection requirement, 10-90% of the adjusting stroke is completed 6000 times; according to the same detection principle, one movement process of the upper sliding rail 5 between the first sensor 2 and the fourth sensor 12 is 0-100% of adjustment travel, each movement travel is blocked by the first telescopic pin 17 and the fourth telescopic pin 20 and stays at the locked-rotor position for 2 seconds, and according to the detection requirement, 2000 times of adjustment travel of 0-100% can be completed.

After 8000 times of reciprocating motion detection of the upper sliding rail 5, the motor 14 and the transmission shaft 15 enter a high-temperature state, according to the same detection principle, the upper sliding rail 5 needs to perform 2000 times of reciprocating motion in 10% -90% of the adjusting stroke, and perform 1000 times of reciprocating motion in 0-100% of the adjusting stroke range, but the locked-rotor position does not need to be detected for 2 seconds in each time of reciprocating motion, that is, the PLC does not need to control the telescopic pin to rise to block the upper sliding rail 5, and only needs to control the forward transmission or reverse rotation of the motor 14 to enable the upper sliding rail 5 to perform reciprocating motion in 10% -90% of the adjusting stroke and 0-100% of the adjusting stroke range.

The first detector 3 is able to monitor the first sensor 2 and the second sensor 4; the second detector 11 can monitor the third sensor 10 and the fourth sensor 12, if no sensing signal is generated in the sensors within 30 seconds, the damage of the motor or the damage of the transmission shaft is judged, the first detector 3 sends a signal to the PLC, and the PLC control device stops detecting.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
