[0026] The movable top device 5 is connected to the connecting seat 23 through a sliding seat 24, and a clamping mechanism 3 is installed on the outer side of the sliding seat 24. The clamping mechanism 3 includes an upper clamping plate 31, a lower clamping plate 32, and a fixed plate 34 connected to the inner ends of the two clamping plates.

[0032] The diameter detector is a laser detection head 13.

[0033] Working principle: Before testing shaft parts, the two ends of the rotating shaft to be tested are pressed and connected between the movable center and the fixed center, and the two centers are used to perform a preliminary fixed connection on the rotating shaft.

[0034] The movable top device is slidably installed through a transmission mechanism, and the transmission mechanism includes a transmission screw and a screw nut in which the transmission screw is mounted, and the movable top device is connected to the screw nut through a connecting seat. After one end of the rotating shaft is connected to the fixed top device, the driving motor is started, driving the transmission screw to start rotating, and the rotational motion of the transmission screw is converted into the linear motion of the movable top device through the screw nut, and the movable top moves toward the rotating shaft to be detected until the movable top is pressed and connected to the end of the rotating shaft.

[0035] Furthermore, in order to guide the movable top device, a guide mechanism is arranged above the base plate across the left and right sides. The guide mechanism clamps the transmission screw therein, and the movable top device and the guide mechanism are installed through a sliding seat, forcing the movable top device to move linearly along the guide rod of the guide mechanism, thereby maintaining the linear and smooth movement of the movable top device and ensuring that the movable top and the fixed top always maintain the same horizontal line.

[0036] After the initial installation of the rotating shaft, the user can lock the movable top device through the clamping device to lock the position of the movable top device on the transmission screw. It should be noted that the clamping device includes an upper clamping plate and a lower clamping plate that clamp the guide rod and the transmission screw therein, and the upper and lower clamping plates are respectively provided with clamping holes and through grooves for inserting the guide rod and the transmission screw. After the initial installation of the rotating shaft, the user rotates the adjustment screw to make the clamping hole and the guide rod have an interference fit, locks the position of its fixed plate on the guide rod, restricts the guide mechanism from moving outward, restricts the outward movement of one side of the movable top device, and at the same time, the inward movement of the other side of the movable top device is restricted by the pressure of the rotating shaft, and the left and right directions of the movable top device are restricted, so that the rotating shaft is firmly and stably fixed. Similarly, after the inspection of the rotating shaft is completed, the adjustment screw is rotated in the opposite direction, the clamping hole is opened, and the movable top device can move left and right along the guide rod again.

[0037] After the rotating shaft is fixed, the diameter detector is slid by the slide rail mechanism, and the diameter detector is adjusted in position. The diameter detector can perform all-round diameter detection on the rotating shaft, collect and organize the diameter data of the rotating shaft, and achieve the purpose of diameter detection of the rotating shaft parts. Among them, the diameter detector can be set as a laser detection head.

[0038] In the movable top device, the movable top is extended outward or retracted inward by a driving connecting rod to be movably connected with the rotating shaft to be tested. In the fixed top device, the fixed top is extended out of the fixed top seat to be fixedly connected with the rotating shaft to be tested.

[0039] The diameter detection device in this case has a simple structure and is easy to operate. It can automatically detect the diameter of the shaft using a laser detection head. It has high detection accuracy and efficiency, requires less manual intervention, and has low labor costs. At the same time, a movable top device is set to flexibly install the top of one end, which is suitable for use with shafts of multiple lengths and specifications. It has strong flexibility and can therefore be widely promoted.

[0040] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
