Description

Engine body tappet hole drilling equipment
Technical field
The utility model relates to the tooling device using in a kind of diesel engine production, is a kind of engine body tappet hole drilling equipment specifically.
Background technology
A plurality of tappet holes on engine body are word order, are arranged in the inner chamber of body fuselage, in the time of boring, drill bit will be put in housing and operate.If hole and not only waste time and energy successively with a drill bit, be also difficult to control hole spacing, easily cause operate miss, affect product quality.If a plurality of drill bits are arranged on same rig according to the quantity of engine body tappet hole, rig once completes the bore operation of a plurality of tappet holes, both can enhance productivity, can also once complete the orientation problem of all drilled hole, avoid locating the inaccurate product quality that affects.But often volume is larger for the rig of a plurality of drill bits of this installation, head section cannot be put in to the operation of housing inner chamber, the head section of rig is stayed outside, and the drill bit that puts in housing must have longer drilling rod just can get at the position of boring, and longer drilling rod in use easily fractures.
Summary of the invention
The purpose of this utility model be to provide a kind of simple in structure, easy to use, can once complete the long engine body tappet hole drilling equipment of a plurality of tappet hole bore operations, accurate positioning, drilling life of bit.
In order to reach above object, the technical scheme that the utility model adopts is: this engine body tappet hole drilling equipment comprises frame and rack-mounted drilling tool, described drilling tool comprises drive motors, transmission case, drill bit, below transmission case, float platen is installed, below described platen, be installed with support set, on platen and support set, be provided with can receiving drill bit through hole, and the through hole on platen and the through hole on support set coaxially arrange, the upper end of drill bit is arranged in transmission case, 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, are vertically fitted with floating axle on hangers, and the lower end of floating axle is run through and is inserted on platen, on the floating axle between hangers and platen, is set with spring.
Lower surface at platen is provided with elasticity backstay, described elasticity backstay comprise be fixedly connected on platen lower surface block rubber, be inlaid in the cylindrical metal bar below block rubber.
Described support set comprises and is fixedly connected on the connecting plate of platen lower surface, the housing of rectangular configuration, described housing is vertical with connecting plate to be arranged, on housing, be at least provided with two through holes that are parallel to each other, 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 housing, and another right-angle side of reinforcement is fixedly connected on the lower surface of connecting plate.
Adopt after technique scheme, this engine body tappet hole drilling equipment is simple in structure, easy to use, can once complete a plurality of tappet hole bore operations, accurate positioning, drilling life of bit are long.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
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 drilling equipment described in the utility model comprises frame 1 and is arranged on the drilling tool in frame 1, described drilling tool comprises drive motors 3, transmission case 2, drill bit 4, drive motors 3 drives by transmission case 2 a plurality of drill bits 4 synchronous rotaries that are arranged in a row, drilling tool is arranged in 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.For convenient, use, in the frame 1 below drilling tool, charging workbench 20 is also installed, engine body to be holed is placed on charging workbench 20.Below transmission case 2, float platen 5 is installed, below described platen 5, be installed with support set 6, on platen 5 and support set 6, be provided with can receiving drill bit 4 through hole, and the through hole on the through hole on platen 5 and support set 6 coaxially arranges, the upper end of drill bit 4 is arranged in 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, are vertically fitted with floating axle 8 on hangers 7, and the lower end of floating axle 8 is run through and is inserted on platen 5, on the floating axle 8 between hangers 7 and platen 5, is set with spring 9.When this floating connection mode makes to be pressed on engine body under 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, at the lower surface of platen 5, be provided with elasticity backstay 10, described elasticity backstay 10 comprise be fixedly connected on platen 5 lower surfaces block rubber 11, be inlaid in block rubber 11 cylindrical metal bar 12 below.During work, cylindrical metal bar 12 injects in locating hole reserved on engine body, play pinpoint effect, the block rubber 11 being arranged between cylindrical metal bar 12 and platen 5 makes to have certain telescopic resilience between the two, avoids cylindrical metal bar 12 and engine body to produce rigid collision and causes displacement.
As shown in Figure 2, described support set 6 comprises and is fixedly connected on the connecting plate 61 of platen 5 lower surfaces, the housing 62 of rectangular configuration, the setting vertical with connecting plate 61 of described housing 62, on housing 62, be at least provided with two through holes that are parallel to each other, the sidewall of described through hole is provided with through hole 63, the outer surface of the housing 62 between two through holes 63 is provided with reinforcement 64, the rectangular triangle of described reinforcement 64, a right-angle side of reinforcement 64 is fixedly connected on housing 62, and another right-angle side of reinforcement 64 is fixedly connected on the lower surface of connecting plate 61.The housing 62 of one group of rectangular structure of such two through holes has good rigidity, can play good supporting role to drilling rod; Meanwhile, the heat that the through hole 63 arranging on housing can also produce drill bit comes out in time, avoids the service life of heat affecting drill bit.
