Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: a novel rocker arm drill indexing template comprises a rocker arm drill stand 12 and a fixed mount 2 arranged at the bottom of the rocker arm drill stand 12, wherein four corners of the fixed mount 2 are fixedly connected with the rocker arm drill stand 12 through fixed bolts 4, a gasket 11 is sleeved outside the fixed bolts 4, a bearing shell 6 is arranged inside the fixed mount 2, and the inner side of the bearing shell 6 is provided with a bearing inner ring 9, the bottom of the surface wall at the side of the bearing inner ring 9 is provided with four sliding chutes 14, and the insides of the four chutes 14 are all connected with supporting rods 8 in a sliding way, one ends of the four supporting rods 8, which are close to the center of the bearing inner ring 9, are all fixedly connected with a joint frame 7, the other ends are all fixedly connected with vertical rods 15, the bottom of the bearing inner ring 9 is provided with a rotating disc 13, and the turntable 13 is provided with four guide grooves 16, the four guide grooves 16 are respectively connected with the vertical rod 15 in a sliding way, so that the vertical rod 15 is clamped inside the guide groove 16 when the rocker drill bit rotates, and the four fitting frames 7 stably support the drill bit to rotate.

Specifically, as shown in fig. 1, four side frames 10 are fixedly connected to the outer side of the bearing housing 6, studs 5 are screwed to the outer sides of the four side frames 10, and the top ends of the four studs 5 are attached to the outer side of the fixed frame 2, so that the fixed frame 2 and the bearing housing 6 are fixed to each other by the four studs 5.

Specifically, as shown in fig. 1, the fixing frame 2 is provided with inner grooves 3 in four directions, and the four inner grooves 3 are slidably connected to four studs 5, so as to control the position of the adjusting bearing housing 6 by screwing the adjusting studs 5 to the side frame 10 and slidably connecting the studs 5 to the inner grooves 3.
