Description
Technical field
The utility model relates to a kind of drill jig.
Background technology
As shown in Figure 1, existing drill jig, comprises the mould body in annular, described mould body offers some jacks along its circumference, be provided with drill bushing in described jack, located by taper bolt between drill bushing and mould body, by brill locating hole joined by drill bushing and mould body, then locate with taper bolt, because drill bushing needs quenching, the distortion of locating hole can be caused, and often change a drill bushing, all need again to join brill locating hole with mould body, operate very inconvenient.
Summary of the invention
The purpose of this utility model is to overcome the defect existed in prior art, provides a kind of drill jig, and dismounting, replacing are conveniently.
For achieving the above object, the technical solution of the utility model there is provided a kind of drill jig, comprise the mould body in annular, described mould body offers some jacks along its circumference, be provided with drill bushing in described jack, described drill bushing upper surface edge part offers locating slot, passes through Bolt to position between described drill bushing and described mould body, described mould body offers the screwed hole matched with described bolt, the bolt head of described bolt is positioned at described locating slot.
As preferably, described bolt is hexagon socket head cap screw.
As preferably, described locating slot is circular arc.
As preferably, described detent groove surface has quench hardened case.
As preferably, described mould body center offers the shoulder hole for positioning workpieces.
Advantage of the present utility model and beneficial effect are: owing to locating slot to be opened in the edge part of drill bushing upper surface, and when installation and demounting bolt, only locating slot need be aimed at screwed hole, centering is more convenient, is then convenient to the operations such as dismounting, replacing.
Accompanying drawing explanation
Fig. 1 is prior art schematic diagram;
Fig. 2 is schematic diagram of the present utility model.
Wherein: 1, mould body; 2, drill bushing; 3, locating slot; 4, bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 2, a kind of drill jig, comprise the mould body 1 in annular, described mould body 1 offers some jacks along its circumference, be provided with drill bushing 2 in described jack, described drill bushing 2 upper surface edge part offers locating slot 3, is located between described drill bushing 2 and described mould body 1 by bolt 4, described mould body 1 offers the screwed hole matched with described bolt 4, the bolt head of described bolt 4 is positioned at described locating slot.
For the ease of dismounting and the installation of bolt 4, described bolt 4 is hexagon socket head cap screw, and described locating slot 3 is in circular arc.
In order to improve the intensity of locating slot 3, described locating slot 3 surface has quench hardened case.
Conveniently Workpiece fixing, described mould body 1 center offers the shoulder hole for positioning workpieces
During installation, first locating slot 3 is aimed at screwed hole, because locating slot 3 is positioned at drill bushing 2 upper surface, therefore centering is very convenient, is then tightened by bolt 4, now bolt head is positioned at the lower surface that locating slot 3 pushes against locating slot 3, drill bushing 2 and mould body 1 are located, structure is simple, and location is convenient, be convenient to dismounting and change drill bushing 2, increasing work efficiency.
The above is only preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
