To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of travelling gear boring positioning structure, its key are：Including drill jig sleeve, mandrel, pressing plate, hold-down bolt, institute
It is assembled using modular construction to state drill jig sleeve, in the accommodating cavity that is centrally formed of the drill jig sleeve, the accommodating cavity wall
Portion is provided with support level, fixes the mandrel at the center of the accommodating cavity bottom, being offered in the upper end of the mandrel can
With the matched screw hole of hold-down bolt, which is arranged concentrically with the mandrel, by the pressing plate, hold-down bolt to being threaded through
Workpiece on mandrel carries out end face compression, is provided with the top of the drill jig sleeve spacing spacing for being carried out to side surface of workpiece
Structure, location hole is further opened with the side of the drill jig sleeve, the location hole is through the both sides of the drill jig sleeve and the core
Axis.
Further, the drill jig sleeve includes generally U-shaped intermediate, passes through fastening respectively in the both sides of the intermediate
Baffle is bolted, the intermediate surrounds the accommodating cavity with baffle, the position limiting structure is set on the baffle.
Further, the position limiting structure is limiting tooth or limiting slot.
Further, the support level is divided into both sides opposite in drill jig sleeve, and the top of the support level is formed
The slope surface centroclinal to drill jig sleeve.
Further, pressing plate structure substantially in disk form, offers U-type groove, and the bottom of the U-type groove on the pressing plate
Portion extends to the center of pressing plate, and the hold-down bolt is located in the U-type groove.
The remarkable result of the utility model is：It is simple in structure, it is practical and convenient, in Drilling operation, first by work hole to be drilled
Part is sheathed on mandrel, and is carried out by position-limit mechanism spacing, is then compressed workpiece by pressing plate and hold-down bolt, at this time work
Inclined-plane, side and the end face of part are fixed, therefore the drilling on inclined surface processing of workpiece, above-mentioned mistake can be carried out by location hole
Journey is easy to operate, can effectively improve production efficiency；Precision after drilling at the same time is high, is effectively guaranteed product quality；Using mould
The combining structure of block, is readily produced, the low cost of frock, it is easy to accomplish and promote.
Brief description of the drawings
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the internal structure schematic diagram of the utility model；
Fig. 3 is that Fig. 1 removes the structure diagram after pressing plate；
Fig. 4 is the structure diagram of the pressing plate.
Embodiment
Specific embodiment of the present utility model and operation principle are described in further detail below in conjunction with the accompanying drawings.
As shown in FIG. 1 to 3, a kind of travelling gear boring positioning structure, including drill jig sleeve 1, mandrel 2, pressing plate 3, compression
Bolt 4, the drill jig sleeve 1 is assembled using modular construction, described accommodating in the accommodating cavity that is centrally formed of the drill jig sleeve 1
Support level 5 is provided with the middle part of cavity wall, the mandrel 2 is fixed at the center of the accommodating cavity bottom, in the upper of the mandrel 2
End offer and can be arranged concentrically with 4 matched screw hole of hold-down bolt, the screw hole with the mandrel 2, by the pressing plate 3,
Hold-down bolt 4 carries out end face compression to the workpiece being threaded through on mandrel 2, is provided with the top of the drill jig sleeve 1 for work
Part side carries out spacing position limiting structure 6, location hole 7 is further opened with the side of the drill jig sleeve 1, the location hole 7 runs through
The both sides of the drill jig sleeve 1 and the mandrel 2.
As shown in Figures 1 and 2, the drill jig sleeve 1 includes generally U-shaped intermediate 1a, in the both sides of intermediate 1a
Baffle 1c, the intermediate 1a and baffle 1c are connected with by fastening bolt 1b respectively and surround the accommodating cavity, in the baffle
The position limiting structure 6 is set on 1c.
In the present embodiment, the position limiting structure 6 is limiting slot, and the width of the limiting slot is thick with the key teeth with travelling gear
