[0039] When the part detection work is carried out, the movable turntable 209 can be driven by a plurality of groups of magnetic wheels 208 to assist in limiting work; when facing a tubular and irregular part, the electric sliding table 201 is started to drive the transmission plate 202 to move towards the first pressure sensor 102, and then the first motor 203 is started to drive the fixed plate 206 to rotate, and then the inner wall of the tubular part is attached to the outer wall of the two groups of movable turntables 209, and then the magnetic wheel 208 is started to magnetically attract the movable turntable 209, so that the movable turntable 209 cannot rotate flexibly, and then the electric push rod 207 is started to drive the movable turntable 209 to rise, and the movable turntable 209 rises while correcting the position of the irregular tubular part, keeping the bottom point of the part in the arc-shaped groove and in contact with one of the second pressure sensors 205, and then the pressing detection work is carried out, which improves the flexible detection effect of irregular cylindrical parts.

[0040] As shown in the example, Figure 5 and Figure 6As shown, the adjusting assembly 3 comprises a fixed collar 301 fixedly sleeved on the outer wall of the pressing column 105, one end of a plurality of groups of first compression springs 302 is installed in an annular array on the bottom of the fixed collar 301, the other end of the plurality of groups of first compression springs 302 is connected with a movable collar 303, a plurality of groups of auxiliary pipes 304 is distributed in an annular array on the bottom of the fixed collar 301, a group of third pressure sensors 305 is installed on the bottom of each group of the auxiliary pipes 304, a plurality of groups of linear drives 306 is distributed in an annular array on the bottom of the movable collar 303, a group of rectangular blocks 307 is installed on the output end of each group of the linear drives 306, a group of second motors 308 is installed on the bottom of each group of the rectangular blocks 307, and a group of monitoring structures 309 is installed on the outer wall of each group of the rectangular blocks 307.

[0041] For irregular part detection, first place the part on the placing disc 101, then start the hydraulic push rod 104 to push the pressing column 105 to abut against the surface of the part, then start the linear drive 306 to drive the rectangular block 307 to move towards the part, and real-time monitoring is conducted through the monitoring structure during the movement, and the second motor can be started to drive the detection structure to rotate during subsequent detection to improve the flexibility of detection. Since the part is of irregular structure, the moving distance of each group of linear drives 306 also changes according to the shape of the part, and after moving to the specified position, a plurality of groups of the abutting plates 415 are driven to abut against the part, thereby improving the compatibility of position adjustment.

[0042] For example, Figure 7 and Figure 8As shown, the detection assembly 4 comprises a first connecting plate 401, the top of each group of the first connecting plate 401 is drivingly connected to the output end of one group of the second motor 308, one side wall of each group of the first connecting plate 401 is provided with a group of fixed discs 402, one side wall of each group of the fixed disc 402 is provided with a group of third motors 403, the output end of each group of the third motor 403 is drivingly connected to a group of second connecting plates 404, one side wall of each group of the second connecting plate 404 is symmetrically provided with two groups of sliding pipes 405, one side wall of each group of the fixed disc 402 is provided with a group of annular grooves 406, each group of the sliding pipe 405 is slidingly connected in the annular groove 406, the bottom of each group of the second connecting plate 404 is provided with a group of mounting plates 407, the bottom of each group of the mounting plate 407 is provided with a group of third connecting plates 408, one side wall of each group of the third connecting plate 408 is provided with a group of slideways 409, two groups of magnetic attraction strips 416 are arranged in each group of the slideway 409, the bottom of each group of the mounting plate 407 is provided with a group of fourth connecting plates 410, a group of cavities 411 is arranged in each group of the fourth connecting plate 410, a group of fourth pressure sensors 412 is arranged in each group of the cavity 411, one end of each group of the second compression spring 413 is arranged on the bottom of each group of the fourth connecting plate 410, a group of magnetic attraction blocks 414 is arranged on the other end of each group of the second compression spring 413, the magnetic attraction block 414 is magnetically attracted to the magnetic attraction strip 416, a group of close plates 415 is arranged on the bottom of each group of the magnetic attraction block 414, and each group of the close plate 415 is slidingly connected in the slideway 409.

[0043] In order to better close the parts and prevent the problem of disconnection in subsequent pressing, the third motor 403 drives the second connecting plate 404 to rotate, the second connecting plate 404 drives the third connecting plate 408 to rotate at the same time, and then the close plate 415 with a larger contact area is closed on the part, and at the same time, the fourth pressure sensor 412 arranged in the cavity 411 is brought into contact with the surface of the part, and in the subsequent pressing detection process, the local pressure detection work can be carried out through the fourth pressure sensor 412, and at the same time, the third motor 403 drives the second connecting plate 404 to rotate, and the sliding pipe 405 slides in the annular groove 406, which can better protect the output shaft of the third motor 403 in the subsequent pressure work, improve the structure protection effect, and prolong the service life of the structure.

[0044] The hydraulic push rod 104 is started to push the pressing column 105 to press the part for detection. In the detection process, the pressing column 105 slowly descends and drives the abutting plate 415 to slide in the slide 409 for slow pressing. After the detection position and pressing failure are detected, the magnetic attraction strip 416 can be powered to make the magnetic attraction strip 416 and the magnetic attraction block 414 magnetically attract and connect. When the magnetic attraction strip 416 and the magnetic attraction block 414 are in the magnetic attraction state, the second compression spring 413 cannot buffer again. This makes several groups of abutting plates 415 form a fixed connection effect on the part. At this time, the gravity of the pressing column 105 acts on the first compression spring 302 to buffer the gravity of the subsequent pressing column 105. The gravity only acts on the first pressure sensor 102 to avoid damage to the part at the detection point and improve the pressure detection effect of the mechanical part processing.

[0045] The magnetic attraction wheel 208 is started to drive the movable turntable 209 to assist in limiting work.

Then the magnetic attraction wheel 208 is started to magnetically attract the movable turntable 209, so that the movable turntable 209 cannot rotate flexibly. Then the electric push rod 207 is started to drive the movable turntable 209 to rise. The movable turntable 209 rises at the same time to correct the position of the irregular tubular part in parallel. The bottom point of the part is kept in the arc-shaped groove and in contact with one of the second pressure sensors 205. Then the pressing detection work is carried out to improve the flexible detection effect of the irregular cylindrical part.

The bottom point of the part is kept in the arc-shaped groove and in contact with one of the second pressure sensors 205. Then the pressing detection work is carried out to improve the flexible detection effect of the irregular cylindrical part.

[0047] When the irregular part is detected, the part is placed on the placing disc 101, then the hydraulic push rod 104 is started to push the pressing column 105 to contact the surface of the part, then the linear driver 306 is started to drive the rectangular block 307 to move close to the part, and the real-time monitoring is conducted through the monitoring structure 309 during the movement, and the second motor 308 can be started to drive the detection structure to rotate during the subsequent detection process to improve the flexibility of detection. Since the part belongs to an irregular structure, the moving distance of each group of linear drivers 306 is also changed according to the shape of the part. After moving to the specified position, a plurality of groups of the adhering plate 415 are adhered to the part, and the compatibility effect of position adjustment is improved.
