The piston rod of the up-and-down moving cylinder 6 is connected to the slider 4 on the linear guide rail 7, and the slider 4 is connected to the suspension platform. In the initial state, the piston of the up-and-down moving cylinder 6 is extended.

[0029] In one embodiment, the limiting platform drive mechanism includes a stepper motor 8, a synchronous belt 10, a first synchronous pulley 12, a second synchronous pulley 9, a lead screw 13, and a lead screw nut 11. The lower end of the lead screw 13 is connected to the first synchronous pulley 12, the output shaft of the stepper motor 8 is connected to the second synchronous pulley 9, the first synchronous pulley 12 and the second synchronous pulley 9 are connected and synchronously driven by the synchronous belt 10, and the lead screw nut 11 is connected to the limiting platform 14. The platform is initially located below the designated position.

[0030] In one embodiment, the circumferential standard bar 2 includes a suspension end and a calibration section. The circumferential standard bar 2 is rotatably and vertically suspended on a suspension platform through the suspension end, and the calibration section is provided with a number of calibration areas with different circumferences.

[0031] In one embodiment, the suspension end of the circumferential standard bar 2 is an inverted conical structure, and the suspension platform is provided with a slot that matches the shape of the suspension end.

[0032] In one embodiment, the calibration section is provided with a measurement section of 8 mm diameter, a measurement section of 5 mm diameter, and a verification section of 6.5 mm diameter, arranged sequentially from bottom to top. Figure 3 As shown, the circumferential standard bar 2 has two measurement positions with different diameters and a verification position C arranged from bottom to top. The diameter of measurement position A is 8mm, the diameter of measurement position B is 5mm, and the diameter of verification position C is 6.5mm.

[0033] In one embodiment, the upper part of the clamping and rotating mechanism is the laser measurement area 16, and the up and down moving mechanism also includes a measurement guide device 1. The up and down driving device and the measurement guide device 1 are connected by a quick-release structure. The measurement guide device 1 includes a vertically arranged guide cylinder. In the initial state, the guide cylinder is located directly above the laser measurement area 16 and corresponds to the clamping hole of the clamping and rotating mechanism.

[0034] like Figure 4 and Figure 5 As shown, in one embodiment, the rotating mechanism includes an electric gripper, a rotating assembly, and a stepper motor 154. The electric gripper is disposed at the gripping hole. The rotating assembly includes a first synchronous pulley 151, a second synchronous pulley 152, and a synchronous belt 153.

[0036] Combination Figure 1 , Figure 2 and Figure 3 As shown, in automatic calibration mode, stepper motor 8 drives synchronous belt 10 to rotate lead screw 13, which in turn drives lead screw nut 11 and limit stage 14 to move vertically to the preset position of the controller program. Simultaneously, the front and rear drive devices activate, driving the up and down drive devices forward, causing the measurement guide device to move aside, clearing the space above the laser sensor's measurement area. The circumferential standard rod 2 then enters the measurement area above the laser sensor 17. Next, the cylinder of the up and down movement mechanism activates, driving the circumferential standard rod 2 downwards until its bottom contacts the top surface of the limit stage 14. At this point, measurement position A on the circumferential standard rod is exactly within the laser sensor's measurement area. Subsequently, the clamping and rotating mechanism closes, clamping the circumferential standard rod and driving it to rotate one revolution. The laser sensor 17 synchronously collects data, obtaining the circumferential value of measurement position A.

[0037] After measurement at position A is completed, the clamping and rotating mechanism releases, and the platform moving mechanism drives the platform downwards a certain distance, causing measurement position A to move out of the laser measurement area 16, while simultaneously causing measurement position B to enter the through hole in the laser measurement area 16. The clamping, rotating, and measuring process is repeated to obtain the circumferential value of measurement position B. The platform is then lowered again, causing measurement position B to move out, and verification position C to enter the laser measurement area for circumferential measurement. After all measurements are completed, each motion mechanism automatically resets to its initial position according to the control command.

[0038] In manual calibration mode, all motion mechanisms remain in their initial positions. At this time, the measurement guide device 1 is located above the laser measurement area, and its quick-release structure allows for easy removal of the measurement guide device 1, after which manual calibration can be performed.

[0039] The beneficial effects of this utility model are as follows: 1. Through multi-axis linkage control (forward and backward, up and down, platform movement and rotation), the precise positioning and automatic measurement of the circumferential standard bar in the measurement space are realized, and the whole process is automated, which significantly improves the calibration efficiency.

[0040] 2: By using a circumferential standard bar with multiple standard diameter positions (for measurement and verification), multi-point calibration and verification can be completed in a single installation, improving the comprehensiveness and reliability of the calibration.

[0041] 3. It has both automatic and manual calibration modes, making it flexible in operation and adaptable to different application scenarios and maintenance needs.

[0042] 4. The structure is reasonably designed, the motion logic is clear, and the reset function ensures the safety and convenience of using the equipment.

It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
