[0033] In operation, the workpiece to be detected is placed in the middle of the two fixed assemblies 12, and then the fixed assemblies 12 are slid, and when the two fixed assemblies 12 are slid to the specified position, the shaft part can be fixed by the two fixed assemblies 12, at this time, the lead screw 13 is rotated, and with the rotation of the lead screw 13, the position of the detection device in the middle of the lead screw 13 can be adjusted until the detection end of the detection device contacts the middle of the shaft part, and the run-out detection of the shaft part can be realized. To detect the shaft part over time, the lead screw 13 needs to be continuously rotated to adjust the position of the detection device to contact the shaft part. With the passage of time, wear will occur between the lead screw 13 and the base of the lead screw 13. At this time, the water tank 14 is filled with lubricating liquid, and then the water pump inside the water tank 14 is started. With the start of the water pump, the lubricating liquid inside the water tank 14 will fill the inside of the water pipe 15. At this time, with the continuous start of the water pump, the lubricating liquid continuously moves inside the water pipe 15 until it moves to the end of the water pipe 15, and then it is sprayed out from the end of the water pipe 15. At this time, the lubricating liquid will enter the inside of the conical cylinder 17. When the lubricating liquid in the conical cylinder 17 reaches a certain amount, it will press the rubber plug 18, causing the rubber plug 18 to fall. At this time, with the falling of the rubber plug 18, the lubricating liquid will flow out of the inside of the conical cylinder 17 and fall to the top of the lead screw 13. When the lubricating liquid in the conical cylinder 17 is used up, the weight 110 will pull the rope 19 to pull the rubber plug 18 back to the bottom of the conical cylinder 17.

At this time, with the sliding of the two fixed assemblies 12, the elastic belt 33 can be stretched, causing the elastic belt 33 to deform. When the shaft part is being detected, if the two fixed assemblies 12 are not stable in fixing the shaft part, the shaft part will fall off. At this time, by setting the elastic belt 33, the falling shaft part can be caught. With the start of the water pump, the water pump will shake. With the passage of time, the water pipe 15 will come off. At this time, by installing the sleeve 4 in the middle of the water pipe 15 and then connecting the sleeve 4 and the top of the operating table 1 with the fixed rod 41, the water pipe 15 can be fixed in the specified position. When the lubricating liquid in the water tank 14 falls to the top of the fixed assembly 12, part of the lubricating liquid contacts the fixed assembly 12 to lubricate the fixed assembly 12, and the other part of the excess lubricating liquid falls to the bottom of the fixed assembly 12 and then flows to the top of the operating table 1, causing the accumulation of lubricating liquid on the top of the operating table 1. At this time, by installing the collection box 5 at the bottom of the fixed assembly 12, the waste lubricating liquid can be collected and treated uniformly.The limiting assembly 61 is installed on the top of the support plate 2, at this time, as the counterweight 110 pulls the pull rope 19, the limiting assembly 61 can limit the pull rope 19, as the two fixed assemblies 12 slide, the elastic band 33 can be stretched, when the elastic band 33 is stretched, the elastic band 33 will be deformed, at this time, as the elastic band 33 is stretched each time, the brush 7 at the bottom of the elastic band 33 can clean the top of the operation table 1 once, in order to limit and protect the shaft part, the hook 32 needs to be hung in the inside of the fixed ring 31, at this time, by arranging the brush 7 in the inside of the fixed ring 31, the friction between the fixed ring 31 and the hook 32 can be increased.
