Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the embodiments of the present invention, and obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-3, the key pulling clamp for rapidly positioning the camshaft gear with the induction block comprises a clamp body 2, a key pulling guide sleeve 3, a support 6, a positioning pin 7 and a positioning block 8, wherein the key pulling guide sleeve 3 is fixed on the clamp body 2, the support 6 is fixed on the clamp body 2, two ends of the positioning pin 7 are installed in a slotted hole formed in the top of the support 6, the positioning block 8 is installed on the positioning pin 7, and the positioning block 8 rotates around the positioning pin 7; the pull key guide sleeve 3 is fixed on the clamp body 2 through a guide sleeve fixing bolt 4; the bracket 6 is fixed on the clamp body 2 through a bracket fixing bolt 5.
