In front of the movable rod 33, the lower surface of the positioning block 31 is rotatably connected with a rotating shaft 38, the lower surface of the rotating shaft 38 is fixedly connected with a connecting sleeve rod 39, the lower surface of the connecting sleeve rod 39 is fixedly connected with a connecting sleeve 41, and the lower surface of the connecting sleeve 41 is provided with a detection The head 4, the front of the detection head 4 is provided with a rectangular groove 44, the circumferential surface of the movable column 15 slides through the upper surface of the fixed plate 16, the lower surface of the movable column 15 is fixedly connected to the upper surface of the movable rod 33, and the inner wall of the conveyor belt 21 slides the sleeve Connected to the circumferential surface of the fixed seat 11, the detection device 3 is directly below the upper surface of the conveyor belt 21, the lower inner wall of the rectangular groove 44 is fixedly connected with a fixed column two 45, the upper surface of the fixed column two 45 is fixedly connected with a spring two 43, a spring two The upper surface of 43 is fixedly connected with a fixed column one 42, the upper surface of the fixed column one 42 is fixedly connected to the lower surface of the connecting sleeve 41, the inner wall of the connecting sleeve 41 is movably attached to the surface of the detection head 4, and the starter motor 24 drives its output shaft valley. The fixedly connected gear 22 rotates, and when the gear 22 rotates, the gear teeth 23 meshing with it begin to move, so that the conveyor belt 21 fits on the surface of the fixed seat 11 and rotates. Intermittent rotation, through the above design, the workpiece can be detected on the upper surface of the conveyor belt 21 for a long enough time, and the linkage device of the conveying device 2 can make a number of workpieces stored on the upper surface of the conveyor belt 21. After the last workpiece is detected, it can be The detection of the next workpiece is directly carried out, which greatly improves the work efficiency. When the workpiece is detected, the operator can pull the handle 13 to drive the movable column 15 to move upward, so as to make the movable column 1 and the movable column 1 move upward. 5. The fixedly connected movable rod 33 moves upward, and drives the connecting column 2 37 connected in front of the movable rod 33 to move upward, so that the connecting rod 35a fixedly connected with it moves upward, so that the shifting column 34 is retracted inward through the connecting column 1 35 As a result, the positioning block 31 is lowered down by one gear.

Replacing the detection device greatly saves the cost. Since the spring one 36 is squeezed when the movable rod 33 moves upward, the spring one 36 starts to rebound after the positioning block 31 is lowered by one gear. At this time, the operator does not apply pressure to the handle 13. If the upward force is applied, the connecting column-35 remaining on the inner wall of the positioning block 31 will continue to play a fixed role on the positioning block 31. When the downshift is still required, the operator can repeat the operation.

When the bottom surface of the detection head 4 contacts the workpiece, it drives the second fixed column 45 to move upward. The second squeeze spring 43 is fixedly connected with the connecting sleeve 41. It plays a fixed role to move the detection head 4 upward. When it is not in contact with the workpiece, the spring II 43 rebounds to reset the detection head 4. Through the above design, the detection head 4 will not be deformed due to the extrusion of the workpiece, which further protects the detection head 4. the device and prolong the service life of the device.

working principle:

The first step: start the motor 24 to drive the gear 22 that is fixedly connected to the output shaft valley to rotate. When the gear 22 rotates, the gear teeth 23 that mesh with it start to move, so that the conveyor belt 21 fits on the surface of the fixed seat 11 and rotates. Because the circumference of the gear 22 There are only some gear teeth on the surface, so the conveyor belt 21 will rotate intermittently. Through the above design, the workpiece can be detected on the upper surface of the conveyor belt 21 for a long enough time.

Step 2: Several workpieces can be stored on the upper surface of the conveyor belt 21 by the linkage device of the conveying device 2. After the previous workpiece is detected, the next workpiece can be detected directly, which greatly improves the work efficiency.

The third step: when the workpiece is detected, the operator can pull the handle 13 to drive the movable column 15 to move upward, so that the movable rod 33 fixedly connected with the movable column 15 moves upward, and drives the connecting column 2 37 connected in front of the movable rod 33 to rotate. Moving up, the connecting rod 35a fixedly connected to it is moved upward, so that the shifting column 34 is retracted inward through the connecting column 1 35 to cause the positioning block 31 to drop down a gear. When the device is stretched, the inspection work can be successfully completed, and the compatibility of the device inspection is increased, and there is no need to replace the inspection device due to the inconsistency of the specifications of the workpiece, which greatly saves the cost.

Step 4: Since the spring one 36 is squeezed when the movable rod 33 moves upward, the spring one 36 starts to rebound after the positioning block 31 drops a gear, and the operator does not exert upward force on the handle 13 at this time, then this The connecting column 1 35 remaining on the inner wall of the positioning block 31 continues to play a fixed role on the positioning block 31. When the downshift is still required, the operator can repeat the operation. Through the above design, the positioning block 31 can be lowered in layers. , to avoid collision of the detection head 4 due to the positioning block 31 falling too fast, and greatly increase the service life of the device.

Step 5: By rotating the connecting shaft 38 on the lower surface of the positioning block 31, the connecting sleeve 39 can be rotated so that the detection head 4 can perform multi-angle detection on the workpiece, which greatly improves the detection quality.

Step 6: When the bottom surface of the detection head 4 contacts the workpiece, it drives the second fixed column 45 to move upward, and the second squeeze spring 43 is fixed by the fixed column one 42 fixedly connected with the connecting sleeve 41 to make the detection head 4 move upwards. When not in contact with the workpiece, the spring II 43 rebounds to reset the detection head 4. Through the above design, the detection head 4 will not be deformed by the extrusion of the workpiece, which further protects the device and improves the service life of the device.
