The utility model content:
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides a kind of operating efficiency and machining accuracy high porous drilling machine.
In order to realize the foregoing invention purpose, the utility model has adopted following technical scheme:
A kind of porous drilling machine, comprise power set, transmission mechanism, drill bit assembly, anchor clamps and workbench, described anchor clamps are positioned at the centre of described workbench, described drill bit assembly is made up of a plurality of drill bits that are distributed in the anchor clamps both sides, and each described drill bit all is in transmission connection by transmission mechanism and described power set.
The utility model also has following attached technical characterictic:
Totally eight on described drill bit is evenly distributed on the anchor clamps both sides.
Described transmission mechanism is a gear transmission structure.
The utility model has been owing to adopted above technical scheme, thereby has following advantage with respect to prior art:
The utility model adopts many drill bit structures, and on workbench, be provided with motorcycle cylinder cap special fixture, during work, place on the anchor clamps cylinder cap fixing, set the position of each drill bit, power-on, power set drive each drill bit by transmission mechanism and rotate synchronously, until each drill bit behind drilling bore hole on the cylinder cap, the both sides drill bit assembly is withdrawn, take out cylinder cap this moment, and put cylinder cap to be processed again, the work that goes round and begins again like this; This utility model is finished being operated in the work period of originally needing that multistep finishes, has improved operating efficiency greatly, and in addition, the position of each drill bit is fixed, thereby can effectively guarantee the positional precision between each hole, deviation can not occur.
The specific embodiment:
As shown in Figure 1, a kind of porous drilling machine that provides according to the utility model, comprise power set 1, transmission mechanism 2, drill bit assembly 3, anchor clamps 4 and workbench 5, transmission mechanism 2 is a gear transmission structure, anchor clamps 4 are positioned at the centre of workbench 5, drill bit assembly 3 is made up of a plurality of drill bits 31 that are distributed in anchor clamps 4 both sides, each drill bit 31 all is in transmission connection by transmission mechanism 2 and power set 1, totally eight on drill bit 31, be evenly distributed on anchor clamps 4 both sides, cylinder cap is installed in the anchor clamps 4, and each drill bit 31 can be simultaneously processed the hole of cylinder cap both sides, has improved production efficiency, simultaneously, the position of each drill bit 31 is fixed, thereby can effectively guarantee the positional precision between each hole, deviation can not occur.
