The transmission shaft 23 is in threaded connection with the positioning pin 24, so that the positioning pin 24 can be detached, different flange models can be switched and produced, only the positioning pin 24 needs to be replaced, and the flange assembling device is convenient and fast.

The transmission shaft is sleeved with a shaft sleeve 25, the upper end part of the shaft sleeve 25 is provided with an end cover 26, and the end cover 26 can prevent impurities such as scrap iron from entering.

A first retainer ring 27 is arranged at a position of the transmission shaft 23 close to the end cover 26, and a second retainer ring 28 is arranged at a position of the inner wall of the shaft sleeve 25 corresponding to the first retainer ring 27.

A spacing ring 29 is arranged between the transmission shaft 23 and the inner wall of the shaft sleeve 25, and bearings 20 are arranged at the positions corresponding to the two ends of the transmission shaft 23 and the spacing ring 29. In specific implementation, the bearing 20 may be an angular contact bearing 20, and the angular contact bearing 20 may prevent a force applied to the shaft from directly acting on the motor 22, thereby preventing the motor 22 from being damaged. The motor 22 may employ a servo motor 22 in order to control the amount of rotation.

In this embodiment, the first driving member 12 and the second driving member 33 are both air cylinders. The support frame 21 is connected to the piston rod of the second driver 33.

Be provided with a plurality of position fine setting blocks 34 on the mounting panel 32, through position fine setting block 34, can adjust the horizontal position of whole subassembly to conveniently adjust with the concentricity of manipulator.

Because the flange is a circular structure, a plurality of hole sites are generally arranged on the flange along the circumferential direction, the arc section where the hole sites are located can be defined as a virtual arc section, the arc sections between adjacent hole sites are defined as solid arc sections, the lengths of the solid arc sections are different, the flange is driven by the servo motor 22 to rotate at a constant speed, the sensor 13 sets a projection distance and a projection mode, a signal projected onto the solid arc section of the flange is 1, a signal projected onto the virtual arc section of the flange is 0, the PLC program sets the servo motor 22 to operate in a relative pulse mode, 100000 pulses are generated when the motor 22 rotates for 1 circle, during the rotation process of the flange, the pulse value recorded by the PLC internal register D is calculated from 0 in real time, the calculation is started in an incremental mode until the motor 22 stops operating or reaches a set pulse value, and when the reset is started again next time, the register continues to be calculated. The moment when the laser signal just projects and passes through the surface of the solid arc segment, namely the signal is 1, is called a sensing rising edge signal, the moment when the signal is 0, namely the signal is 0, on the surface of the solid arc segment, is called a sensing falling edge signal, the program is set to calculate the pulse value D1 of the light-receiving solid arc segment from the current value of the register D, when the signal is sensing falling edge, namely the moment when the solid arc segment leaves the light-receiving point of the sensor, the pulse value D2 of the solid arc segment is cut off, the pulse value D11 of the light-receiving solid arc segment is D2 (falling edge cut-off pulse value) -D1 (rising edge start pulse value) through the formula, therefore, when the flange has 6 solid arc segments, the flange rotates one circle, D11 calculates the pulse value of the 6 solid arc segments, and by comparing the pulse values of the 6 solid arc segments, the proportional relation between the solid arc segments and the pulse values can be easily obtained, the longer the solid arc segment, the higher the pulse value D11 when the received light is collected. In order to make a distinction obvious, one of the solid arc segments (for example, the longest solid arc segment) can be selected as a locating reference, in the PLC program, the solid arc segment D11 (after 10 tests to obtain an average value thereof) is used as a program judgment reference value D22, and as the flange belongs to a casting piece, a certain difference exists in the boundary of the flange, ± 1000 pulse values are set as error values, and a locating judgment formula is obtained: (the judgment reference value D22-1000) is less than or equal to the light receiving pulse value D11 is less than or equal to (the judgment reference value D22+ 1000). When the program operation meets the formula relationship, the locating motor 22 stops operating immediately, and the current flange state is the locating OK.

When the flange lifting device works specifically, after the conveying line 4 conveys the flange to the position corresponding to the position searching assembly 1 and the position locating assembly 2, the second driving piece 33 of the lifting assembly 3 drives the position locating assembly 2 to ascend to lift the flange, and the flange is separated from the conveying line 4. The first driving part 12 of the locating component 1 drives the sensor 13 to move above the flange (specifically, the position of the sensor can be set to correspond to the locating characteristic position set by the flange), the motor 22 receives a signal and drives the transmission shaft 23 to rotate clockwise at a constant speed, after the rotation of a certain angle, the sensor 13 senses that the characteristic arc length of the flange is matched with the pulse value of the arc length set by a program, the locating is completed, and the motor 22 stops immediately. After the locating is completed, the sensor 13 is reset, and after the flange is completely taken by the additionally arranged material taking device, the second driving part 33 is reset to wait for the next flange.

The utility model also provides a transfer chain 4, including aforementioned a mechanism is sought to the flange that is used for transfer chain 4.

Example 2

In this embodiment, the sensor 13 is a vision sensor 13, the vision sensor 13 is generally a camera, and the deviation angle of the flange is detected by photographing and fed back to the industrial personal computer for processing, and the motor 22 receives the driving force to drive the transmission shaft 23 to rotate clockwise at a constant speed by a specific angle to complete locating. The rest of the structure is the same as that of example 1, and redundant description is omitted.
