The quality detection method of the direct transmission set comprises an air tightness detection step, wherein the air tightness detection step comprises the following three steps:
step one, forming a sealed cavity:
inserting a connecting piece or a deflector rod of the direct transmission set into a detection slot and forming a sealed cavity inside the detection slot;
step two, inflation:
an inflation inlet which is hermetically communicated with the inside is arranged on the upper side surface of the detection slot, gas is injected into the sealed inflation inlet through a gas source, a control valve and a gas pipe, then the control valve is closed, and an initial pressure value is measured through a hydraulic sensor arranged on the gas pipe;
thirdly, judging whether air is leaked:
closing the control valve, and measuring the air pressure value in the air delivery pipe as a leakage detection air pressure value through a hydraulic sensor after a preset time;
judging the magnitude of the leak detection air pressure value and the initial air pressure value, and if the leak detection air pressure value is equal to the initial air pressure value, the air tightness detection of the direct transmission set is qualified; and when the leak detection air pressure value is smaller than the initial air pressure value, the air tightness detection of the direct transmission set is unqualified.
The quality detection method of the direct transmission set can detect the air tightness quality of the direct transmission set, so that the use safety of the direct transmission set is better ensured.
And in the third step, rotating a transmission shaft of the direct transmission set within a preset time to form dynamic seal detection.

Wherein, the transmission shaft of the direct transmission group is rotated by driving the rotatable part connected with the transmission shaft on the direct transmission group outside the detection slot.
In this way, both ends of the transmission shaft of the direct transmission set are rotatable parts (one end is a connecting piece fixedly connected with the transmission shaft, and the other end is a deflector rod fixedly connected with the transmission shaft).
And the air tightness detection step is realized by adopting a direct transmission set air tightness detection mechanism below.
The direct drive set mass detection method further comprises a torque detection step having the following
Firstly, clamping and fixing a shaft sleeve;

The direct drive set torque detection mechanism has the advantages that:
1. the torque detection can be directly completed on the direct transmission set assembling device, and the assembling and detecting efficiency is improved.
2. The torque detection structure and the detection operation are simple. The torque of the direct transmission set can be judged to be qualified or not only by measuring the 'transmission shaft rotation parameter' through the rotation parameter acquirer and comparing the 'transmission shaft rotation parameter' with the 'preset driving parameter' of the motor.
The motor of the rotary driver is a servo motor, and the servo motor forms the rotation parameter acquirer.
The technical personnel in the field know that the control circuit of the servo motor controls the driving current of each phase of the motor through the feedback of the current loop, the speed loop and the position loop, so that the speed and the position of the servo motor can accurately run according to the preset operation, and the preset driving parameters can be obtained. In addition, the servo motor is also a three-closed-loop control comprising a current loop, a speed loop and a position loop, and the three-closed-loop control can respectively feed back the angular acceleration, the angular speed and the rotating position of the motor operation, so that the 'transmission shaft rotating parameter' can be measured.
For example, when the direct drive unit is jammed, the servo motor needs to be larger than a preset torque or cannot drive the shift lever and the transmission shaft of the direct drive unit to rotate at all, so that the servo motor can measure a real-time transmission shaft rotation parameter through a control circuit of the servo motor, and after the real-time transmission shaft rotation parameter is compared with a preset drive parameter, a judgment signal can be transmitted to a controller (PLC), and the controller reminds a worker, or directly screens out the direct drive unit with unqualified torque through a manipulator.

In practice, the shaft coupler 404 and the assembling cylinder 405 are preferably made of copper materials, and the assembling column 406, the connecting rotary disc 407 and the rotating rod 401 are all made of plastics.
In the structure of the above-mentioned rotary driver, magnetic attraction between outer magnetic sleeve 402 and inner magnetic sleeve 403 forms rated torque, when the transmission shaft jamming of direct drive group torque, the motor still drives assembly cylinder 405 and outer magnetic sleeve 402 through coupler 404 to rotate, but inner magnetic sleeve 403, assembly post 406, connection carousel 407 and dwang 401 then overcome magnetic attraction and can not rotate enough under the transmission shaft jamming of direct drive group torque, like this, proximity sensor judges the number of turns of connection carousel 407 rotation through the number of times of passing through of detecting and detecting with lug 408, when this number of turns is inconsistent with motor shaft number of turns, then direct drive group torque is unqualified.
Therefore, the structure of the rotary driver is simple, rated torque can be automatically recovered, and the rotary driver can be used for torque detection continuously, permanently and reliably, and has a good using effect. In addition, the magnetic torque generated by the outer magnetic sleeve 402 and the inner magnetic sleeve 403 is smaller, and the driving lever is driven to rotate by the smaller magnetic torque, so that the torque detection is stricter, and the transmission reliability of the direct transmission set is better ensured.
