DETAILED DESCRIPTION

[0020] The present invention is further described below in conjunction with the accompanying drawings and examples. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Needless to say, those skilled in the art will recognize that the described embodiments may be modified in various ways without departing from the spirit and scope of the present invention. Therefore, the drawings and descriptions are illustrative in nature and are not intended to limit the scope of protection of the claims.

[0021] like Figures 1 to 5 As shown, the combined inspection tool of the butterfly valve toothed disc and handle is used for the inspection of the butterfly valve toothed disc 1 and the butterfly valve toothed disc 1 after assembly with the toothed disc handle 2. Specifically, it is mainly used to inspect whether the size and position of the toothed disc mounting hole 8, the position of the toothed disc positioning block 10, the size of the toothed disc center hole 4, the position of the closed position bayonet 13, and the clearance between the toothed disc block and the toothed disc handle 2 meet the requirements. It can complete multiple inspection tasks at one time, and is simple to operate, easy to use, and has high inspection efficiency. Specifically, it includes an inspection tool chassis 3, the center of which is provided with a center hole inspection groove 5 for inspecting the center hole 4 of the butterfly valve toothed disc 1, and a handle inspection assembly device for installing the toothed disc handle 2 can be detachably provided in the center hole inspection groove 5. The handle inspection assembly device can inspect the size and position of the center hole 4 of the toothed disc, and can also realize the assembly inspection of the toothed disc handle 2.

[0022] The handle inspection assembly device includes a cylindrical inspection assembly base 6 which is sleeved in the center hole inspection groove 5 and the center hole 4 of the toothed disc, and the outer wall of the inspection assembly base 6 just matches the inner wall of the center hole inspection groove 5 and the center hole 4 of the toothed disc, and the inspection assembly base 6 can just be inserted into the two, indicating that the position and size of the center hole 4 of the toothed disc are accurate. The top of the inspection assembly base 6 is fixedly connected with a square column inspection assembly pin 7, and the toothed disc handle 2 is plugged into the inspection assembly pin 7. The purpose of assembling the toothed disc handle 2 is to inspect the gap between it and the toothed disc block on the butterfly valve toothed disc 1, that is, the toothed disc handle 2 is rotated to the position of the closed position bayonet 13, and a feeler gauge is inserted into the gap between the toothed disc block and the toothed disc handle 2. The size of the gap between the two can be known according to the feeler gauge used, so as to judge whether the gap meets the production requirements.

[0023] The inspection tool chassis 3 is fixedly provided with mounting hole positioning columns 9 corresponding to each toothed disc mounting hole 8 on the butterfly valve toothed disc 1, and the outer diameter of the mounting hole positioning columns 9 matches the aperture of the toothed disc mounting hole 8. When inspecting the butterfly valve toothed disc 1, the mounting hole positioning columns 9 are inserted into the corresponding toothed disc mounting holes 8, so that the inspection and assembly of the butterfly valve toothed disc 1 is realized. The smooth assembly of the two indicates that the size and position of the toothed disc mounting hole 8 are accurate. The inspection tool chassis 3 is also provided with a positioning block inspection groove 11 corresponding to the toothed disc positioning block 10 on the butterfly valve toothed disc 1. After the butterfly valve toothed disc 1 and the inspection tool chassis 3 are assembled, the toothed disc positioning block 10 is just located in the positioning block inspection groove 11, indicating that the size and position of the toothed disc positioning block 10 are accurate. An inspection and assembly guide surface 12 with a gradually decreasing outer diameter can be correspondingly provided at the top of each mounting hole positioning column 9, so that the butterfly valve toothed disc 1 can be quickly inspected and assembled with the inspection tool chassis 3.

[0024] In this embodiment, the inspection tool chassis 3 located outside the mounting hole positioning column 9 is further provided with a bayonet inspection groove 14 for inspecting the closed position bayonet 13 on the butterfly valve toothed disc 1, and a bayonet positioning column 15 is detachably inserted in the bayonet inspection groove 14. After the butterfly valve toothed disc 1 and the inspection tool chassis 3 are assembled, the bayonet positioning column 15 is taken out and inserted into the bayonet inspection groove 14. If the upper end of the bayonet positioning column 15 is just located in the closed position bayonet 13, it means that the closed position bayonet 13 is accurately positioned.

[0025] The inspection tool chassis 3 includes a tool chassis body 31, a circular inspection support boss 32 is provided at the top of the tool chassis body 31, the center hole inspection slot 5, the mounting hole positioning column 9, and the positioning block inspection slot 11 are all provided on the inspection support boss 32, and the bayonet inspection slot 14 is provided on the tool chassis body 31 outside the inspection support boss 32. The inspection support boss 32 can lift the butterfly valve gear disc 1 to a certain height so as to avoid the handle tip 16 at the bottom of the gear disc handle 2 so that it can smoothly rotate along the inspection assembly pin 7.
