Wherein, the control instruction is that a positioning block of the checking fixture 5 is adjusted according to the hole position distance of the seat 3, if the distance between two sides of the seat wall is 48 as a result of scanning a certain seat 3, the diameter of the hook rod is 5cm, the size of the seat frame of the seat 3 is 34cm in positive width, 48cm in length and 33cm in side hole distance. The checking fixture 5 calls a control instruction, namely a programming instruction, of a built-in database in a corresponding model (size) according to the data, then reads the programming instruction through the PLC, and the read instruction moves through the servo motor 16 to adjust each moving mechanism of the checking fixture.
When the instruction is sent to the checking fixture 5, the servo motor 16 of the checking fixture 5 is first reset to the initial position, that is, the L-limited block 7 and the machine base plate 15 are set to the zero position, which is the return thread at this time, so the feeding speed is F800. When the moving instruction is received, the moving instruction is in an adjusting state, and the hole distance and the initial position are close threads, and the detection tool 5 cannot detect that the hole position has deviation or deviation, so that the feeding speed is automatically slowed to be less than the feeding speed of F200 when the positioning block is close to the arrival point.
Wherein, examine utensil 5 side length and be 70cm, just wide for 60cm, servo motor 16 commentaries on classics point is the central point. The three positioning blocks are positioned right at the rotating point, and initial positions at two ends are used as mirror image surfaces. The rated voltage of the servo motor 16 is 220V, the rated current is 4.5A, the rated power is 1200W, the rated torque is 4.0, and the rated rotating speed is 3000R/s.

Each positioning block respectively takes the rotating point of the servo motor 16 as a central axis, the A-shaped positioning block 24, the B-shaped positioning block 23 and the positioning block are tied on the same axis of an X axis, the Y axis is-10 and +10 respectively, the C-shaped positioning block 22 is tied on the same line of the Y axis, the X axis is-10, the Z axis looks at the height of the positioning block, and the loading frames are tied on the same height level. Use servo motor 16 to turn the point as the central point, zero point promptly, it is in the use, move with servo motor 16 central point, can transmit the locating piece that the automobile model of examining utensil 5 was used in the time of can through control system, and when zero point moved, can subtract its unilateral distance that can corresponding locating piece hole point apart from zero point according to using different locating pieces automatically.
The machine table bottom plate 15 of the checking fixture 5 is provided with 4 moving mechanisms which are respectively mirror-image opposite surfaces, the rectangular angles on the machine table bottom plate 15 are arranged, three surfaces are limited and fixed through the upright installation of 2 side vertical plate supports 14 and the Z-axis vertical plate support 12, the Z-axis servo motor 16 at the bottommost position is locked on the machine table bottom plate 15 and is tightly attached to the wall surface of the side vertical plate support 14, and the shaft coupling 17 on the rotating shaft of the screw rod 13 plays a parallel role in low-speed buffering. The fixed rotating plate on the rotating shaft of the Z-axis screw rod 13, the floating plate vertical support 18, the shaft passing plate 19 and the Y-layer positioning plate 11 are matched and locked together, and the transverse plate support plays a role of double balance support. The Y-axis servo motor 16 is loaded on the Y-layer positioning plate 11, the motion process of the Y-layer positioning plate is the same as that of the Z-axis servo motor 16 and a relative mechanism thereof, and the shaft coupling 17 on the rotating shaft of the screw rod 13 plays a role in buffering and high-speed parallel. The fixed rotating plate on the rotating shaft of the Y-axis screw rod 13 is matched and locked with the supporting block 21, the X-layer positioning plate 10 and the Y-layer positioning plate 11 in parallel, and plays a role of balance support. An X-axis servo motor 16 is loaded on the X-layer positioning plate 10, the motion process of the X-layer positioning plate is the same as that of the Y-axis servo motor 16 and a relative mechanism thereof, and a coupler 17 on a rotating shaft of a lead screw 13 plays a parallel role in low-speed buffering. The fixed rotating plate on the rotating shaft of the X-axis screw rod 13 is matched and locked with the supporting block 21, the X-layer positioning plate 10 and the Y-layer positioning plate 11 in parallel, and plays a role of balance support. The T-shaped block 8 is used as an auxiliary support for single-arm support, so that the positioning block mounting plate 6 is more stably supported, and the stress is uniform. When the servo motors 16 on each layer rotate, the sliding shafts 9 are arranged beside the servo motors to be convenient to tightly and complementarily, the positioning support locking plates 15 and the support blocks 21 are arranged on the sliding shafts 9 to be fixedly pressed, synchronously and slowly moved, and after the sliding shafts are moved to be in place, the convex holes on the positioning blocks A, B, C on the X-axis of each moving mechanism are matched with the holes of the front row seats 3 of the automobile for detection.
If the underframe of a seat 3 of a certain model is 34 mm wide and the center distance of the side holes is 30cm, the hole positions are A-shaped positioning blocks 24. At this time, X, Y, Z shaft servo motors 16 of the detection tools 5 rotate in sequence, and the moving distance of the Z shaft is a fixed distance, so that the distance between any underframe and the surface of the detection tool 5 is kept at 15cm. The height of the seat 3 is 34cm, the height of the checking fixture 5 is 60cm, and the moving mode is that the checking fixture 5 is used for measuring the distance between the single side of the seat 3 and 17cm = the moving distance between the single side of the seat and the single side of the seat, which is 13 cm. The Y-axis is rotated in one direction to a positive width distance, i.e. 13cm (minus 10 of the zero point of the Y-axis distance of the positioning block A has been removed). The center distance of the side holes of the underframe of the seat 3 is 30cm, the side length of the checking fixture 5 is 70cm, and the moving mode is that the single-side distance of the checking fixture 5 is 35 cm-the single-side distance of the seat 3 is 15cm = the single-side moving distance of the closing. The center distance of the X-axis unidirectional rotation hole is 20 cm. When the feeding speed is close to the end point 5cm from F500 in the programming information, the servo motor 16 will rotate slowly at the close-to-end speed F200 set by the interval until the detection point is reached.
After the checking fixture 5 is adjusted, the robot automatically hooks and takes out the seat 3 on the jig disc 2 at the last station of the production line 1 and places the seat into the checking fixture 5 with the position of the positioning block adjusted. After seat 3 put into, board bottom plate 15 can respond to whether seat 3 correctly puts into, and is sensing seat 3 and has placed errorlessly after, opens automatically the electromagnetic chuck that board bottom plate 15 was accompanied in order to fix seat 3, begins to detect automatically immediately, then waits until electromagnetic chuck self-closing, shows promptly that the detection ends, manipulator 4 can be automatic will examine seat 3 hook in the utensil 5 and snatch out and place the chair frame of putting after the inspection finishes this moment. If the hole positions are not aligned or other problems occur, the machine base plate 15 senses abnormality, the electromagnetic chuck cannot be opened, and meanwhile the detection tool 5 can give out 'dripping', 'dripping' and 'dripping' alarm sounds. At the moment, the manipulator 4 takes out the seat 3 claw on the checking fixture 5 and reloads the seat 3 claw, and if the checking fixture 5 still gives out an alarm sound after reloading, the manipulator 4 takes out the seat 3 claw in the checking fixture 5 and places the seat 3 claw on the unqualified seat frame; or if the seat is not qualified, the manipulator 4 can also grab the seat 3 in the checking tool 5 out of the hook and place the seat to the unqualified seat placing frame.
When the manipulator 4 places the seat 3 on the seat placement table (no matter the seat is placed on the qualified seat placement table after being qualified in inspection or placed on the unqualified seat placement table after being unqualified in inspection), the servo motors 16 of the X, Y, Z shafts of the 4 moving mechanisms of the inspection tool 5 are reset to the initial positions first, namely the positions where the L limiting blocks 7 and the machine table bottom plate 15 are mutually set to zero, namely zero, so that the accuracy of the positioning block point of the inspection tool 5 is ensured, and the feeding speed is F800 because the no-load return stroke is zero. At the same time, the production line 1 starts rolling again, so that the seat 3 to be inspected rolls to the end station. In a cycle, when the scanner scans the RFID card at the bottom of the jig tray 2, the production line 1 automatically stops rolling. Meanwhile, the scanner sends the model result obtained by scanning the RFIF at the bottom of the jig disc 2 to the control system, so that the data of the checking fixture 5 matched with the model in the database of the checking fixture 5 built in the control system is called, and the data contains a control instruction. When the checking tool 5 receives the moving command, the state is adjusted, the feeding speed is carried out according to the programming command, but when the near-end distance is reached, the checking tool 5 still can automatically decelerate to the near-end speed.
