[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model relates to a bearing housing hole position inspection tool, such as Figures 1-4 As shown, it includes a base plate 1, and a guide plate 2 is fixedly connected to the middle of the top surface of the base plate 1 to position the bearing. The guide plate 2 has a through-hole 3, and the positioning pin 3 is used to accurately position the bearing.

[0021] Among them, such as Figure 3As shown, the guide plate 2 includes a plate body 201, an embedding hole 202 and a slot 203. The plate body 201 has an embedding hole 202 extending along a vertical axis inside. A matching positioning pin 3 is inserted into the embedding hole 202. The top surface of the plate body 201 has a slot 203 extending towards the center.

[0022] Furthermore, the side wall of the positioning pin 3 is fixedly connected to a slot plate 4 located above the base plate 1. The slot plate 4 has a hole inside, and there are opposing steel inserts 5 in the hole of the slot plate 4. A movable slot pin 6 is provided between the two sets of steel inserts 5. The slot pin 6 can be adjusted and moved between the two sets of steel inserts 5 so that the end of the slot pin 6 is in close contact with the bearing.
