Detailed Description
As shown in fig. 1, the measuring tool for detecting the radial cylindricity of the lead screw comprises a guide block 6, a connecting block 12, a fixing block 11, a dial indicator 1, an upper measuring head 8 and a lower measuring head 10, wherein the guide block 6 is provided with the dial indicator 1 through a locking nut 2 and a locking sleeve 3, a baffle 4 is arranged between the locking sleeve 3 and the guide block 6, the measuring head of the dial indicator 1 passes through the guide block 6 to be attached to the upper measuring head 8, a spring 5 is arranged between the dial indicator 1 and the upper measuring head 8, the spring 5 is arranged in the guide block 6, a limit pin 7 is arranged at the bottom of the guide block 6 to limit the upper measuring head 8, the top of the fixing block 11 is provided with the lower measuring head 10, and a positioning disc 9 is arranged on the surface of the connecting block 12 between the upper measuring head 8 and the lower measuring head 10.
A cavity which can be used for measurement is formed among the upper measuring head 8, the lower measuring head 10 and the positioning plate 9.
The upper measuring head 8 and the lower measuring head 10 are coaxially arranged.
A handle 13 is arranged at the right side of the connecting block 12.
The working principle and the using process are as follows: the detection method belongs to an indirect detection method. Go up gauge head 8 and lower gauge head 10 coaxial axle center, when last gauge head 8 is flexible in guide block 6, can promote the gauge head of amesdial 1, the pointer on the 1 dial plate of amesdial this moment has the beat, when the distance of last gauge head 8 and lower gauge head 10 is a setting value, returns zero 1 dial plate of amesdial, when surveying other distances again, through the beat of 1 dial plate of amesdial, can calculate the measurement size. When the distance between the axes of the positioning disc 9, the upper measuring head 8 and the lower measuring head 10 is the radius of the excircle of the screw rod raceway, the positioning disc 9 of the measuring tool is attached to the excircle of the screw rod raceway, the upper measuring head 8 and the lower measuring head 10 are respectively attached to the surfaces of the raceways of the measured points, the dial pointer of the dial indicator 1 is reset to zero at the moment, and when the measuring tool is used for measuring the positions of other raceways of the same screw rod, the coaxiality of the screw rod can be seen through the deflection value of the dial indicator 1.
The measuring tool provided by the utility model can be used for seeing the cylindricity of the middle diameter of the screw rod by firstly measuring the middle diameter size of a certain part of the screw rod as a base number and then combining the change of the dial indicator 1 in the actual measuring process, can be suitable for various screw rods with different specifications by replacing the upper measuring head 8, the lower measuring head 10 and the positioning disc 9, and has the advantages of simple operation, accurate measurement, small volume, convenience in carrying and high measuring speed.
