[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The following is combined with Figure 1-5 This application is described in further detail.

[0022] A novel valve stem keyway processing tool includes a processing tool, wherein the processing tool is connected to a stem body 12 of the valve stem, two processing tools are provided, and the two processing tools are respectively arranged at two ends of the stem body 12, and the processing tool plays a positioning role when keying the stem body 12.

[0023] The processing tooling includes a support block 5 and a positioning block 10. The positioning block 10 is connected to the support block 5. The positioning block 10 is provided with a threaded hole 11. A plurality of threaded holes 11 are provided on the positioning block 10. The threaded holes 11 are threadedly connected with a threaded rod 1. The support block 5 is provided with fixing holes 8. The number of the fixing holes 8 is the same as the number of the threaded holes 11. The threaded rod 1 is threadedly connected to the fixing holes 8.

[0024] A V-shaped groove 2 is provided on one side of the support block 5 close to the positioning block 10, and the rod body 12 is pressed against the V-shaped groove 2. A positioning groove 9 is provided on one side of the positioning block 10 close to the support block 5, and the rod body 12 is pressed against the positioning groove 9, and the rod body 12 is between the V-shaped groove 2 and the positioning groove 9.

[0025] When processing the key groove for the rod body 12, the rod body 12 is placed on the V-groove 2 of the support block 5, and then the positioning groove 9 of the positioning block 10 is pressed against the rod body 12, and the threaded rod 1 is threadedly connected to the threaded hole 11 and the fixing hole 8 in sequence. At this time, the rod body 12 is fixed between the positioning block 10 and the support block 5, so that the rod body 12 is not easy to move when in the key groove.
