Detailed Description
Detailed description of the preferred embodiment 1
As shown in fig. 1, a simple tool for measuring a small fillet of a thrust shaft cover comprises a measuring head 1 and a connecting rod 2, wherein the measuring head 1 is connected with the lower end of the connecting rod 2 through a connecting bolt 3; the tail end of the measuring head 1 is a fillet measuring head, the fillet side head is matched with a small fillet 13-1 of a thrust surface of a thrust shaft cover 13 to be detected, when the measuring head is used, a bottom surface of the measuring head 1 is attached to an outer circular surface 13-2 of the thrust surface of the thrust shaft cover 13, a light source is used for irradiating one side of the measuring head 1, human eyes watch the light leakage condition at the other side, and the human eyes rotate a circle along the small fillet (the small fillet 13-1 is distributed on the thrust shaft cover for one circle, as shown in figure 5) to judge the qualified condition of the small fillet.
Specific example 2
As shown in fig. 2 to 5, a simple measuring tool for measuring a small round angle of a thrust shaft cover comprises a measuring head 1 and a connecting rod 2, wherein the measuring head 1 comprises a round angle measuring head, light baffles 1 to 31 and light baffles 1 to 32 which are matched with the small round angle of a thrust surface of the thrust shaft cover are respectively distributed on two sides of the lower part of the round angle measuring head, a light sensing cavity 1 to 1 is formed between the two light baffles, and light sensing elements 1 to 2 are distributed in the light sensing cavity 1 to 1; of course, the present embodiment is also provided with a control circuit and a liquid crystal display module 12; the control circuit is connected with the light sensing elements 1-2 and the liquid crystal display module 12, and the liquid crystal display module 12 is used for displaying the light values of the light sensing elements 1-2 in time. In order to improve the sensitivity of the light sensing element 1-2, the light emitting panels 1-51 and 1-52 are respectively disposed on the outer sides of the two light blocking panels, and the light of the light emitting panels aligns with the small circular angle contact surface of the light blocking panel and the thrust surface of the thrust shaft cover.
