Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to use, can once finish the long engine body tappet hole drill aperture apparatus of a plurality of tappet hole drill hole operations, accurate positioning, drilling life of bit.
In order to reach above purpose, the technical solution adopted in the present invention is: this engine body tappet hole drill aperture apparatus comprises frame and rack-mounted drilling tool, described drilling tool comprises drive motors, transmission case, drill bit, below transmission case, float platen is installed, be installed with support set below the described platen, be provided with on platen and the support set can receiving drill bit through hole, and the through hole on the platen and the coaxial setting of the through hole on the support set, the upper end of drill bit is installed in the transmission case, and the lower end of drill bit is run through in the through hole that is arranged on platen and support set.
The both sides of described transmission case are respectively equipped with hangers, vertically are fitted with floating axle on the hangers, and the lower end of floating axle is run through and is inserted on the platen, and the floating axle between hangers and platen is set with spring.
Lower surface at platen is provided with the elasticity backstay, and described elasticity backstay comprises the block rubber that is fixedly connected on the platen lower surface, be inlaid in the cylindrical metal bar below the block rubber.
Described support set comprises the connecting plate that is fixedly connected on the platen lower surface, the housing of rectangular configuration, described housing is vertical with connecting plate to be arranged, at least be provided with two through holes that are parallel to each other on the housing, the sidewall of described through hole is provided with through hole, the outer surface of the housing between two through holes is provided with reinforcement, the rectangular triangle of described reinforcement, a right-angle side of reinforcement is fixedly connected on the housing, and another right-angle side of reinforcement is fixedly connected on the lower surface of connecting plate.
After adopting technique scheme, this engine body tappet hole drill aperture apparatus is simple in structure, easy to use, can once finish a plurality of tappet hole drill hole operations, accurate positioning, drilling life of bit are long.

Fig. 2 is the structural representation of support set.
Fig. 3 is the structural representation of elasticity backstay.
The specific embodiment
As shown in Figure 1, engine body tappet hole drill aperture apparatus of the present invention comprises frame 1 and the drilling tool that is installed on the frame 1, described drilling tool comprises drive motors 3, transmission case 2, drill bit 4, drive motors 3 drives a plurality of drill bits 4 that are arranged in a row by transmission case 2 and rotates synchronously, drilling tool is installed on the frame 1 by vertically disposed slide rail, and can upper and lower slip under the effect of drive unit, realize the feeding of drill bit.Use for convenience, on the frame 1 below the drilling tool charging workbench 20 is installed also, engine body to be holed is placed on the charging workbench 20.Below transmission case 2, float platen 5 is installed, be installed with support set 6 below the described platen 5, be provided with on platen 5 and the support set 6 can receiving drill bit 4 through hole, and the coaxial setting of through hole on the through hole on the platen 5 and the support set 6, the upper end of drill bit 4 is installed in the transmission case 2, and the lower end of drill bit 4 is run through in the through hole that is arranged on platen 5 and support set 6.
The both sides of described transmission case 2 are respectively equipped with hangers 7, vertically are fitted with floating axle 8 on the hangers 7, and the lower end of floating axle 8 is run through and is inserted on the platen 5, and the floating axle 8 between hangers 7 and platen 5 is set with spring 9.This unsteady connected mode makes when being pressed on the engine body under the drilling tool, platen 5 can be pushed down engine body in advance, and rely on own wt to produce certain pressure, and engine body is fixedly positioning, avoid the moment engine body generation of drill bit work to rock.
As shown in Figure 3, be provided with elasticity backstay 10 at the lower surface of platen 5, described elasticity backstay 10 comprises the block rubber 11 that is fixedly connected on platen 5 lower surfaces, be inlaid in the cylindrical metal bar 12 below the block rubber 11.During work, cylindrical metal bar 12 injects in the locating hole of reserving on the engine body, play pinpoint effect, be arranged on block rubber 11 between cylindrical metal bar 12 and the platen 5 and make and have certain telescopic resilience between the two, avoid cylindrical metal bar 12 and engine body to produce rigid collision and cause displacement.
