"upper", "lower", "left", "right", and the like are used merely to indicate relative positional relationships, and when the absolute position of the object being described is changed, the relative positional relationships may also be changed accordingly.
To maintain the following description of the embodiments of the present invention clear and concise, a detailed description of known functions and known components of the utility model have been omitted.
As shown in fig. 1-2, a roller excircle run-out tolerance testing device comprises a bottom block 1, a first vertical block 2 vertically fixed at the top of the bottom block 1, a second vertical block 3 vertically fixed at the top of the bottom block 1 and positioned at the rear side of the first vertical block 2, a pressure block 4 detachably fixed at the top of the second vertical block 3, and a displacement measuring instrument 5 fixed between the second vertical block 3 and the pressure block 4; the first vertical block 2 and the second vertical block 3 are arranged in a mutually perpendicular mode, a measuring end fixing sleeve of the displacement measuring instrument 5 is transversely inserted and fixed between the top of the second vertical block 3 and the bottom of the pressing block 4, a measuring end telescopic head of the displacement measuring instrument 5 extends forwards to the right side of the first vertical block 2, a U-shaped frame 6 is further fixed on the measuring end telescopic head of the displacement measuring instrument 5, a vertically arranged and rotatable guide wheel 7 is further fixed in the U-shaped frame 6, and a shaft hole 21 is formed between the outer walls of the left side and the right side of the first vertical block 2; the top of the first vertical block 2 is also inserted with a first screw 9 which is vertically arranged; the threaded end of the first screw 9 extends vertically downwards into the shaft hole 21.
An open slot 41 is formed between the outer walls of the front side and the rear side of the bottom of the pressing block 4, a measuring end fixing sleeve of the displacement measuring instrument 5 is transversely embedded into the open slot 41, and the lower side of the measuring end fixing sleeve of the displacement measuring instrument 5 is tightly pressed on the top of the second vertical block 3.
The pressing block 4 is also provided with two second screws 8 which are vertically distributed in an inserted mode, the two second screws 8 are arranged on the left side and the right side of the open slot 41 respectively, and the thread ends of the two second screws 8 are inserted downwards and screwed into the top of the second vertical block 3.
