At the same time, the movable platform 43 defined by the movable slider 442 moves, and the can body held by the can holder 431 on the movable platform 43 moves, so that the position of the can body to be measured is changed.

Preferably, the moving platform 43 is further provided with two sensors for detecting whether there is a to-be-detected tank, the two sensors are oppositely disposed on two sides of the tank clamp 431, the two sensors are disposed in directions that do not block the transportation of the manipulator to the tank, when the manipulator transports the tank to the tank clamp 431, the sensors on two sides detect the tank above, and then the moving structure 44 is started to drive the moving platform 43 to move to the end where the measuring support is disposed, so as to wait for the detection process.

Meanwhile, in order to prevent the situation that the measuring component 45 is loosened or shifted due to direct collision with the measuring component 45 when the tank body to be measured moves transversely, and even the measuring component 45 is damaged due to collision, the setting height of the measuring component 45 on the measuring support 46 in the device is higher than the height of the tank clamp 431 and the tank body to be measured, namely the tank body to be measured cannot be directly contacted with the measuring component 45 in the horizontal moving process, so that the above-mentioned situation is avoided, and meanwhile, in order to smoothly carry out the subsequent external dimension measuring process of the tank body, the device is also correspondingly provided with a tank rotating lifting component 47 for driving the tank clamp 431 to rotate and lift, wherein the middle part of the moving platform 43 is provided with an opening, the tank clamp 431 and the tank rotating lifting component 47 are fixedly connected and are both arranged in the opening, and the tank clamp 431 is positioned above the moving platform 43 in the conventional state, the can transferring lifting assembly 47 is located below the moving platform 43, and the can transferring lifting assembly 47 can push the can clamp 431 to vertically lift and drive the can clamp 431 to rotate.

The can transferring lifting assembly 47 in this embodiment includes a lifting seat plate 471 vertically disposed, a lifting slide rail 472 vertically disposed on the lifting seat plate 471, a clamp seat plate 473 slidable along the lifting slide rail 472, a platform shaft 474 fixed to the clamp seat plate 473 and fixedly connected to the can clamp 431, a rotating structure 475 for rotating the platform shaft 474, and a lifting structure 476 for pushing the clamp seat plate 473 to slide along the lifting slide rail 472. Wherein the elevating structure 476 can drive the jar body and promote to the position that is fit for measuring component 45 to detect, and simultaneously in measurement process, revolution mechanic 475 can rotate the jar body for can detect jar whole circumference's of body size, detection data is more complete accurate.

Preferably, the rotating structure 475 in this embodiment is similar to the rotating structure, and includes a platform shaft 474 fixed to the clamp seat plate 473, a rotating driven wheel connected to the bottom of the platform shaft 474, a rotating driving wheel, a rotating synchronous belt tightly wound around the rotating driven wheel and the rotating driving wheel, and a rotating motor driving the rotating driving wheel to rotate. When the rotating motor rotates, the rotating driving wheel is driven to rotate together with the rotating synchronous belt, the rotating driven wheel tightly wound by the rotating synchronous belt also rotates along with the rotating synchronous belt, and the platform shaft 474 fixed on the rotating driven wheel can also rotate together to realize that the tank clamp 431 of the platform shaft 474 drives the tank body to be tested to rotate.

When the lifting motor 4763 is started and rotates forward to drive the lifting screw 4761 to rotate, because the lifting screw 4761 is hinged and fixed on the lifting seat plate 471, the ball nut 4765 on the lifting screw 4761 rises along with the lifting screw 4761 in the rotating process, and at the moment, the push block 4762 connected with the ball nut 4765 through the compression spring 4764 also rises together, and pushes the clamp seat plate 473 on the other side of the lifting seat plate 471 to slide upwards along the lifting slide rail 472. Similarly, after the measurement of the outer dimension of the tank is completed, the elevator motor 4763 rotates in the reverse direction, the elevator screw 4761 also rotates in the reverse direction, the ball nut 4765 descends, the push block 4762 also descends, and the clamp seat plate 473 also descends slowly along the elevator slide 472 under the pressure of its own weight. Wherein compression spring 4764's setting can make the in-process jar body that awaits measuring and measuring component 45 when taking place the contact provide certain buffering, avoids direct hard contact, and the instrument of protection measuring component 45 can not take place the harm.

Preferably, the upper end and the lower end of the lifting screw 4761 are both provided with a photoelectric switch for detecting the push block 4762. Photoelectric switches at two ends of the lifting screw 4761 can detect positions of the ball nut 4765 and the push block 4762, and when the photoelectric switches at two sides detect the ball nut 4765 and the push block 4762, the industrial personal computer controls the lifting motor 4763 to slow down or stop rotating.

The synchronous motor rotates to drive the synchronous driving wheel to rotate together with the synchronous transmission belt and drive the synchronous driven wheel to rotate so as to realize the rotation of the lifting screw 4761. The design is reasonable according to the existing space, so that the lifting structure 476 and the rotating structure 475 are not interfered with each other, and can be used in a matching way. Meanwhile, the lifting structure 476 and the rotating structure 475 can be just accommodated in the fixed frame 41, so that the volume of the fixed frame 41 does not need to be widened, and the occupied area of the production line is reduced.
