the sleeve 2 is provided with an engaging portion 2a which forms an axial hole engagement with the square head a, for example, if the square head a is a regular hexagonal square head, the engaging portion 2a is an inner hole in a regular hexagonal side, if the square head a is a regular pentagonal square head, the engaging portion 2a is an inner hole in a regular pentagonal side, and if the square head a is a quadrangular square head, the engaging portion 2a is an inner hole in a four side. That is, the shape of the fitting portion 2a is adapted to the shape of the square head a.

In operation, when the square head a is not properly engaged with the engagement portion 2a, the rotary actuator 1 is used to drive the sleeve 2 to rotate so that the square head a can be brought into engagement with the engagement portion 2 a. In this embodiment, the rotary driver 1 is composed of a motor 1c and a transmission shaft 1d, an output end of the motor 1c is fixed to one end of the transmission shaft 1d, and a circumferential surface of the transmission shaft 1d is provided with a limiting step 1 e.

In this embodiment, the structure that is preferably adopted as described above is implemented as follows:

When the rotary driver 1 works, the motor 1c drives the transmission shaft 1d to rotate, and the transmission shaft 1d drives the sleeve 2 to rotate through the connecting part 1 b. When the sleeve 2 needs to move axially, an axial acting force is applied to the sleeve 2, and the sleeve 2 can move axially due to the fixation of the connecting part 1b and the abduction of the strip-shaped hole 2 b.

The lifting driving mechanism is used for driving the rotary driver 1 to lift, the lifting driving mechanism is connected with the rotary driver 1, and the direction of the square head A is kept under the action of the clamping and holding mechanism 10 after the square head A is matched with the matching part 2a, so that the square head A is required to be separated from the sleeve 2 at the moment, the rotary driver 1 is driven to move axially (downwards in the view of the figure) under the action of the lifting driving mechanism, and the purpose of separating the square head A from the sleeve 2 is achieved.

The lifting driving mechanism can be directly connected with the rotary driver by adopting common transmission mechanisms such as an air cylinder, a hydraulic cylinder, an electric screw rod and the like. In view of space saving, in this embodiment, the lifting driving mechanism adopts the following structure: comprises a sliding frame 6 and a lifting driver 8, wherein the sliding frame 6 is provided with a sliding matching part 7; a part of the lifting driver 8 is in sliding fit with the sliding fit part 7, and the lifting driver 8 is connected with the rotating driver 1. More preferably, the lifting driver 8 comprises a telescopic driver 8a, a swing arm 8b and a slide block 8c, the lifting driver 8 is connected to the sliding frame 6, one end of the swing arm 8b is hinged with the output end of the telescopic driver 8a, and the swing arm 8b is also hinged with the sliding frame 6; the slider 8c is slidably fitted to the slide fitting portion 7, and the rotary actuator 1 is fixed to the slider 8 c.

The elastic component 3 is sleeved on the rotary driver 1, one end of the elastic component 3 is abutted against the rotary driver 1, and the other end of the elastic component 3 is abutted against the sleeve 2; in this embodiment, the elastic member 3 abuts against the limit step 1e, and the elastic member 3 preferably employs a spring. When the sleeve 2 is subjected to pressure, the sleeve 2 transmits the pressure to the elastic member 3, causing the elastic member 3 to compress.

One end of the induction component 4 is arranged on the circumferential surface of the sleeve 2 along the circumferential direction of the sleeve 2, a plurality of assembly holes are formed in the circumferential surface of the sleeve 2, the assembly holes can be threaded holes, the number of the induction components 4 can be multiple, the induction components 4 can be screws, one end of the induction component 4 is in threaded connection with the sleeve 2, and the induction components 4 are arranged along the circumferential direction of the sleeve 2.

After the square head A and the matching part 2a form the matching of the shaft hole, the gravity of the square head A drives the sleeve 2 to compress the elastic part 3, and the sensing part 4 moves along with the sleeve 2, so that the other end of the sensing part 4 reaches the sensing range of the sensor 5.

In the initial state, the sensing part 4 is located at one side of the sensor 5, for example, the sensing part 4 is located above the sensor 5, and at this time, the sensing part 4 and the sensor 5 are not located at the same height, and the sensor 5 cannot detect the sensing part 4. After the sleeve 2 moves and compresses the elastic component 3, the sensing component 4 moves along with the sleeve 2, at this time, the sensing component 4 moves to the same height position as the sensor 5, and after the sensor 5 detects the sensing component 4, a detection signal is sent to a controller (not shown in the figure) for the controller to judge that the square head A is matched with the matching part 2 a.

After sleeve 2 reached the limit upper position, sleeve 2 can contact with square head A in advance, receives the effect of square head A gravity, and elastic component 3 is transmitted with gravity to sleeve 2, and elastic component 3 is compressed, and the tension that elastic component 3 formed by the compression in-process is not enough to counter square head A's gravity, and consequently, square head A can keep on bracket 9, promptly, sleeve 2 is at the in-process with square head A contact, and square head A itself can not axial displacement. The contact between the sleeve 2 and the square head a is as follows:

the first case is: the sleeve 2 and the square head A just form the matching of the shaft hole. The square head A is just inserted into the inner hole of the sleeve 2, the sleeve 2 is pushed to move and the elastic component 3 is compressed due to the gravity of the square head A, at the moment, the sleeve 2 drives the sensing component 4 to move to the position with the same height as the sensor 5, the rotary driver 1 drives the sleeve 2 to rotate, the sensing components 4 are in the rotating process, one of the sensing components 4 is detected by the sensor 5, the sensor 5 sends a signal for detecting the sensing component 4 to the controller, the controller judges that the matching part 2a of the sleeve 2 and the square head A are well matched, the square head A is aligned under the state, and meanwhile, the rotary driver 1 stops working.

The second case is: the fitting portion 2a of the sleeve 2 is not axially hole-fitted with the square head a. The method specifically comprises the following steps: the square head a abuts against a part of the axial end face of the matching portion 2a, at this time, the sleeve 2 is pushed to move under the action of the gravity of the square head a and compress the elastic component 3, and the sleeve 2 drives the sensing component 4 to move to the other side of the sensor 5 (for example, the sensing component 4 is located below the sensor 5), that is, the moving distance of the sleeve 2 is greater than that in the first case, so that the sensing component 4 already moves beyond the detection range of the sensor 5 after moving along with the sleeve 2. At this moment, start the rotation driver 1, the rotation driver 1 drives the sleeve 2 to rotate, because the axial end face area of contact of square head A and cooperation portion 2a is little, sleeve 2 is at rotatory in-process, just makes square head A fall into in the cooperation portion 2a very easily. After square head A falls into cooperation portion 2a, give out the bounce-back space for elastomeric element 3, under elastomeric element 3's tension effect, promote sleeve 2 and go upward, make sleeve 2 drive response part 4 move to with sensor 5 same high position, rotary actuator 1 continues to order about sleeve 2 rotatory, a plurality of response parts 4 are at rotatory in-process, one of them response part 4 is detected by sensor 5, sensor 5 sends the signal after detecting response part 4 for the controller, the controller makes the cooperation portion 2a of sleeve 2 and square head A form the good judgement, this kind of state is the direction of square head A alignment promptly, stop rotary actuator 1 work simultaneously.

In any of the above cases where the square head a is aligned, the clamping and holding mechanism 10 operates the square head a so as to hold the hexagonal direction until the square head a is released after being clamped by the next-in-sequence jig.
