Abstract
The utility model discloses a drilling die for a bridge case of an excavator. The drilling case for the bridge case of the excavator comprises a drilling template of the bridge case; a positioning core shaft and a directional chamfered edge core shaft which are used for positioning the bridge case are arranged on the drilling template of the bridge case; and drilling holes which are provided with drilling sleeves of the bridge case are formed on the drilling template of the bridge case. Compared with the prior art, the drilling die for the bridge case of the excavator bridge case has the advantages of being simple in structure, convenient to draw materials, ingenious in design, safe and reliable, guaranteeing the drilling accuracy of bridge case and the like.
Description
Technical field
The utility model relates to a kind of hole drilling die, particularly a kind of hole drilling die for excavator bridge box body.
Background technology
At present, the bridge box body is the large-scale key components and parts of excavator bridge box assembly, it is the cast steel blank, the shape misconduct, bulk is larger, before the processing, next two groups of 16 bolts hole, existing method is after adopting Digit Control Machine Tool to bore 16 location holes, forward on the drilling machine again and process, each workpiece is wanted clamping No. four times like this, four transhipments also will be proofreaied and correct, the centering workpiece carries out numerical control programming and processes this 16 bolts hole, and working (machining) efficiency is extremely low, quality is difficult to again guarantee, be easy to produce waste product, the economy of company caused loss, so prior art is still perfect not.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, practical, draw materials conveniently, the clamping location is quick, a kind of hole drilling die for excavator bridge box body that can guarantee the Drilling operation precision of casing, to overcome the deficiencies in the prior art.
The utility model is constructed as follows: a kind of hole drilling die for excavator bridge box body, comprise bridge box body bushing plate, be provided with positioning core axle and the directed chamfered edge mandrel that to locate the bridge box body at bridge box body bushing plate, be provided with the drill jig hole at bridge box body bushing plate, in the drill jig hole, be provided with bridge box body drill bushing.
Be provided with the lifting bolt of convenient lifting at bridge box body bushing plate.
Be provided with 16 drill jig holes at bridge box body bushing plate.
Owing to adopted technique scheme, at first bridge box body bushing plate is placed on the bridge box body workpiece, bridge box body bushing plate is adjacent to the end face of workpiece locating hole, before inciting somebody to action, location, rear position, then positioning core axle is penetrated in the locating hole, with a left side, location, right position, to locate the chamfered edge mandrel penetrates in the directional hole again, bridge box body bushing plate can not be rotated, play orientation, fasten drill jig and workpiece, the bridge box body is holed by drill jig with regard to available common driller, finish the processing to the hole, compared with prior art, the utility model not only has simple in structure, the easily advantage of drawing materials, and design ingenious, safe and reliable, can guarantee the advantages such as bridge box body Drilling operation precision.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is that the utility model is installed in the structural representation on the bridge box body;
Fig. 3 is the structural representation of bridge box body drill bushing;
Description of reference numerals: 1-bridge box body bushing plate, the 2-positioning core axle, the directed chamfered edge mandrel of 3-, 4-drill jig hole, 5-is drill bushing fixedly, 6-lifting bolt, 7-bridge box body.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Enforcement of the present utility model: a kind of hole drilling die for excavator bridge box body, shown in Fig. 1～3, comprise bridge box body bushing plate 1, be provided with positioning core axle 2 and the directed chamfered edge mandrel 3 that to locate the bridge box body at bridge box body bushing plate 1, be provided with drill jig hole 4 at bridge box body bushing plate 1, in drill jig hole 4, be provided with bridge box body drill bushing 5.
Be provided with the lifting bolt 6 of convenient lifting at bridge box body bushing plate 1.
Be provided with 16 drill jig holes 4 at bridge box body bushing plate 1.
Fixedly drill bushing 5 plays guiding cutter and wear-resisting effect in boring procedure.
When using the utility model, at first positioning core axle 2 is placed in the locating hole of casing 7, prevent process jackshaft housing casing bushing plate 1 move left and right in processing, again by after directed chamfered edge mandrel 3 orientations, bridge box body bushing plate 1 can not rotate, drill jig hole 4 on the bridge box body bushing plate 1 is matched with the hole site that workpiece will bore, then to drilling machine, carry out Drilling operation with crane lifting bridge box body 7, the part that processes not only machining accuracy can reach drawing requirement fully, and improved the working (machining) efficiency of part, saved the time, reduced percent defective, be worthy to be popularized.
