[0027] In the embodiment, the buffer mechanism specifically comprises: a buffer plate 16 fixed on the top end surfaces of the two fixed plates 2, a second circular groove 17 matching the first circular groove 9 is formed on the top end surface of the buffer plate 16, a circular lifting plate 18 is movably connected in the second circular groove 17, a first air bag 19 is arranged below the circular lifting plate 18, a second air bag 20 is embedded in the buffer plate 16 on one side of the first air bag 19, and the first air bag 19 and the second air bag 20 are communicated. The buffer mechanism of the application can buffer and dampen the spare parts when they are placed on the overhauling platform 8, so as to avoid damage to the spare parts caused by knocking.

[0028] In the embodiment, the outer side surface of the circular lifting plate 18 is fixedly connected with six evenly distributed limiting sliding blocks 22, vertical sliding grooves 21 corresponding to the positions of the limiting sliding blocks 22 are formed on the inner wall of the second circular groove 17, and the limiting sliding blocks 22 and the vertical sliding grooves 21 are movably connected. The cooperation of the limiting sliding blocks 22 and the vertical sliding grooves 21 can improve the stability of the up-down movement of the circular lifting plate 18.

[0029] In the embodiment, the fastening mechanism specifically comprises: a fastening seat 11 fixed on the top end surface of the overhauling platform 8, an expansion slot 12 is formed on the top end surface of the fastening seat 11, a fastening block 13 is movably connected in the expansion slot 12, a fastening pin 10 is threadedly connected to one side surface of the fastening seat 11, and one end of the fastening pin 10 penetrates through the fastening seat 11 and is connected with the fastening block 13 through a rotating piece. The fastening mechanism can clamp and fix the spare parts to be detected.

[0030] In the embodiment, the rotating member specifically comprises a rotating groove 14 formed in one end of the fastening block 13, a rotating head 15 rotatably connected inside the rotating groove 14, and the fastening pin 10 having one end penetrating the fastening seat 11 and being fixedly connected with the rotating head 15.

In the worm and gear transmission design, the worm is usually not driven to rotate if only the gear end is stressed. This is because the design principle and self-locking characteristics of the worm transmission determine the stability of the transmission under the action of the reverse torque, and the application further improves the stability of the transmission gear 26 by adding the positioning pin 27 to prevent the transmission gear 26 from rotating when the transmission worm 28 is not rotating.

[0033] The working principle of the utility model is: in use, first, the part to be detected is placed in the first circular groove 9 of the maintenance platform 8, at this time, the part is supported by the circular lifting plate 18 of the buffering mechanism, and after the part is pressed on the circular lifting plate 18, the circular lifting plate 18 is driven to descend along the second circular groove 17, in the process, the gas in the first gas bag 19 is extruded into the second gas bag 20, thereby buffering and damping the part. Subsequently, the part is clamped and fixed by the fastening mechanism, specifically, the fastening pin 10 is screwed, the fastening pin 10 is inserted into the telescopic groove 12, and under the cooperation of the rotating groove 14 and the rotating head 15, the fastening block 13 slowly extends along the telescopic groove 12 and abuts against the part. After the part is clamped and fixed, the cylinder 6 operates to retract the output shaft, drives the maintenance platform 8 and the part to ascend, the worker adjusts the part to the appropriate height for maintenance, the angle of the part can also be adjusted by the rotary drive mechanism, thereby the part is detected at multiple angles. The working process of the rotary drive mechanism is that the handle 24 is screwed to drive the transmission worm 28 to rotate, thereby driving the transmission gear 26 meshing with the transmission worm 28 to rotate, the driving shaft 25 rotates synchronously, thereby driving the corresponding support seat 5 to rotate synchronously, so that the maintenance platform 8 and the part rotate synchronously, and the transmission gear 26 is clamped by the positioning pin 27 to prevent rotation when the transmission worm 28 does not rotate. After the part is detected, the maintenance platform 8 is lowered to the initial state, at this time, the height of the maintenance platform 8 is the lowest, which facilitates the worker to take down the part. The traditional maintenance platform needs the worker to lift the part to a certain height of the detection table for maintenance, but the application can adjust the height of the maintenance platform 8 without affecting the angle adjustment, thereby facilitating maintenance and taking and placing the part. In the embodiment, the model of the cylinder 6 is MA40X300.
