Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling machine used for synchronous belt wheel production. Background Art

[0002] Synchronous belt drive is also called meshing belt drive. It is a meshing drive composed of synchronous belt and synchronous pulley. Its motion and power are transmitted through the meshing of belt teeth and wheel teeth. Compared with friction belt drive, synchronous belt drive can ensure accurate transmission ratio because the belt and pulley transmit motion and power through meshing. There is no relative sliding between the belt and pulley. Therefore, synchronous belt drive is widely used in mechanical transmission devices. As an important component of synchronous belt drive, synchronous pulleys are generally made of steel, aluminum alloy, cast iron, brass and other materials. Drilling machine refers to the general term for machinery and equipment that uses a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object by rotary cutting or rotary extrusion.

[0003] According to Chinese patent CN203526613U, a drilling machine for synchronous pulley production is firstly used to place the synchronous pulley to be drilled in a fixed ring in a fixed assembly, and the adjusting screws around the fixed ring are drilled. The adjusting screws drive the arc plate to move inward to fix the synchronous pulley to prevent the synchronous pulley from moving during the drilling process. Then, the first handle is turned. The first handle drives the gear to move up and down on the first rack through the first rotating plate and the first rotating shaft, and then drives the first moving rod to move up and down on the lower adjusting column to adjust the drilling depth of the synchronous pulley. The first moving rod is fixed by the third screw, and then the drilling The drilling motor in the hole assembly moves on the fixed rod and the slider moves on the guide rail, changing the horizontal position of the drilling power head connected to the drilling motor, and then fixing the horizontal position of the rotating hole power head through the first screw and the second screw, adjusting the drilling position on the synchronous pulley, turning on the drilling switch to start the drilling motor, and the drilling motor drives the drilling power head to rotate, and finally loosening the fourth screw and turning the second handle. The second handle drives the gear to move up and down on the second rack through the second rotating plate and the second rotating shaft, and then drives the second moving rod to move up and down on the upper adjusting column, so that the drilling power head drills the synchronous pulley.

Manual fixing is time-consuming and labor-intensive, and has poor stability, which is not conducive to popularization and use.
