Detailed Description

Referring to fig. 1, 2 and 3, a radial drilling machine for drilling a mold comprises a machine base 1, a workbench 11 is arranged on the machine base 1, a built-in groove 12 is arranged on the workbench 11, a bearing 13 is fixedly embedded in the inner wall of the built-in groove 12, a threaded rod 14 is in interference fit with the bearing 13, the thread directions of the threaded rods 14 in four directions are positively and negatively set according to actual conditions, it is ensured that four clamping seats 19 can be simultaneously and oppositely close to or far away from each other, a threaded sleeve 15 is arranged on the threaded rod 14 in a threaded manner, a limiting rod 16 is fixedly installed on the threaded sleeve 15, a bearing plate 17 covers the workbench 11, a strip-shaped hole 18 is formed in the bearing plate 17, the limiting rod 16 is tightly attached to the strip-shaped hole 18 in a sliding manner, and the clamping seats 19.

Referring to fig. 2, a nut 2 is fixedly embedded in the clamp base 19, a threaded knob 21 penetrates through the thread of the nut 2, and a clamp plate 22 is fixedly mounted on the threaded knob 21, so that errors with precision elements can be compensated.

Referring to fig. 1, a motor 3 is fixedly installed in the built-in groove 12, the model of the motor 3 is 51K120GU-C, a forward and reverse rotation switch and HY2-8 are fixedly installed on the machine base 1, the forward and reverse rotation switch is connected with the motor 3 through a wire, the motor 3 is connected with an indoor 220V power strip through a wire plug in an inserting mode and electrified, a driving bevel gear 31 is fixedly installed on a rotating shaft of the motor 3, and a linkage bevel gear 32 meshed with the driving bevel gear 31 is fixedly installed on the threaded rod 14.
