Above the support plate 11, there is a conveyor belt 13 with an arc-shaped depression in the middle. The arc-shaped depression of the conveyor belt 13 is attached to a cylindrical piston 2. Above the piston 2, there is a positioning structure 3. The positioning structure 3 includes a fixed frame 31, a fixing plate 32, an electric telescopic rod 33, a controller 34, a clamping block 35, a camera 36, an alarm 37 and a connecting plate 38. At the rear side of the conveyor belt 13, there is a fixed frame 31 with an inverted L-shaped cross-section. The bottom of the fixed frame 31 is fixedly connected with the fixing plate 32. Below the fixing plate 32, there is a connecting plate 38. The bottom of the connecting plate 38 is fixedly connected with the electric telescopic rod 33.

On the top of the fixed frame 31, there are a controller 34 and an alarm 37. On the left side of the device main body 1, there is a measurement structure 6. On one side of the fixing plate 32, there is a moving structure 5. The moving structure 5 includes a reciprocating lead screw 51, a moving block 52, a guide plate 53, a motor 54 and a fixing piece 55. By setting the positioning structure 3 and the moving structure 5, it is convenient for the piston 2 to accurately move into the annular measurement device. By setting the camera 36 and the alarm 37 at the positioning structure 3, it is convenient to monitor the process of pushing the piston 2 in real time and can timely remind the user to discover abnormal situations.
[0021] A rubber layer 4 is fixedly connected to the inner side of the clamping block 35. The rubber layer 4 is in close contact with two of the pistons 2, increasing the friction force between the clamping block 35 and the piston 2. The inside of the fixing plate 32 is recessed. A reciprocating lead screw 51 is rotatably connected to the recess of the fixing plate 32. One end of the reciprocating lead screw 51 is fixedly connected to the output shaft of the motor 54. One side of the motor 54 is fixedly connected with a fixing piece 55. The fixing piece 55 is fixedly connected to the top of the fixed frame 31, facilitating the rotation of the reciprocating lead screw 51. The outside of the reciprocating lead screw 51 is provided with a moving block 52. The moving block 52 is fixedly connected with the connecting plate 38, facilitating the movement of the moving block 52 and the electric telescopic rod 33. Guide plates 53 are fixedly connected to the front and rear sides of the moving block 52. The guide plates 53 are slidably connected to the recess of the fixing plate 32, facilitating the left and right movement of the moving block 52.
[0022] Workflow: When the device is running, it is powered by an external power supply. When the special positioning device for transverse continuous dimension measurement of cylindrical objects is in use, first place the main body 1 of this device in a suitable position, place several pistons 2 on the surface of the conveyor belt 13, start the conveyor belt 13, and drive the pistons 2 to move from right to left. After the piston 2 moves below the clamping block 35, the electric telescopic rod 33 drives the clamping block 35 to move downward until the rubber layer 4 inside the clamping block 35 is in close contact with the piston 2. Start the motor 54 to drive the reciprocating lead screw 51 to rotate. Since there is a moving block 52 on the outside of the reciprocating lead screw 51, the front and back sides of the moving block 52 are fixedly connected with guide plates 53, and the guide plates 53 are slidably connected to the recesses of the fixed plate 32, driving the moving block 52 to move leftward. Since the moving block 52 is fixedly connected with the connecting plate 38 and the connecting plate 38 is fixedly connected with the electric telescopic rod 33, the piston 2 below the clamping block 35 is driven to move leftward, pushing the leftmost piston 2 into the annular measuring device in the measuring structure 6 for measurement. During this process, the camera 36 monitors the moving position of the piston 2 in real time throughout the process. When the piston 2 is not pushed or is stuck and stops moving during the movement, the controller 34 can control the alarm 37 to give an alarm to remind the user of an abnormal situation. Then the electric telescopic rod 33 is in a contracted state, driving the clamping block 35 to move upward, and the continuous rotation of the reciprocating lead screw 51 drives the moving block 52 to move rightward. After moving to the starting position, the electric telescopic rod 33 moves downward so that the rubber layer 4 in the clamping block 35 is in close contact with another piston 2. Repeat this process to achieve precise positioning of the piston 2 before measurement. By setting the positioning structure 3 and the moving structure 5, it is convenient for the piston 2 to move into the annular measuring device. By setting the camera 36 and the alarm 37 at the positioning structure 3, it is convenient to monitor the process of pushing the piston 2 in real time and can promptly remind the user to discover abnormal situations.
