The management inconvenience of enterprise is caused, and needs to pay huge tooling production cost.
Therefore, it is necessary to design it is a kind of it is simple in construction, cost is low, and product quality is effectively ensured, improve production efficiency, simultaneously
Also there is the drilling tool of certain versatility.
The content of the invention
In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of travelling gear drilling tool, structure letter
List, cost are low, can effectively ensure that product quality, improve production efficiency.
To reach above-mentioned purpose, the technical solution adopted in the utility model is as follows：
A kind of travelling gear drilling tool, its key are：Including drill jig sleeve, mandrel, pressing plate, hold-down bolt, described
Drill jig sleeve is centrally formed processing district, and the support level for being supported to workpiece slope, institute are provided with the processing district
State drill jig sleeve to be additionally provided with for carrying out side surface of workpiece spacing position limiting structure, be detachably connected at the center of processing district
Mandrel is stated, offers the screw that can be engaged with hold-down bolt in the free end of the mandrel, the screw is along the mandrel
Center line is arranged, end face compression is carried out to the workpiece being located on mandrel by the pressing plate, hold-down bolt, in the drill jig sleeve
Side be further opened with positioning hole, the positioning hole also inwardly runs through the mandrel.
Further, the drill jig sleeve includes generally U-shaped intermediate, passes through fastening respectively in the both sides of the intermediate
Bolt connection has baffle plate, and the intermediate surrounds the processing district with baffle plate, the position limiting structure is set on the baffle plate.
Further, the position limiting structure is limiting tooth or stopper slot.
Further, the support level is divided into both sides relative in drill jig sleeve, and the top of the support level is formed
To centroclinal domatic of drill jig sleeve.
Further, the mandrel is substantially in cylindrical planes to be positioned formed with two on the mandrel, on the drill jig sleeve
It is corresponding to be equipped with fixing bolt and be connected to the positioning plane, to realize the fixation of the mandrel.
Remarkable result of the present utility model is：It is simple in construction, it is practical and convenient, in Drilling operation, first by suitable size
Mandrel be fixed on the processing district center of drill jig sleeve, then hole workpiece to be drilled is sheathed on mandrel, and is entered by position-limit mechanism
Row is spacing, and then by pressing plate and hold-down bolt by Work-sheet pressing, now the inclined-plane of workpiece, side and end face are fixed,
Therefore the drilling on inclined surface that workpiece can be carried out by positioning hole is processed, and said process is simple to operate, can effectively improve production efficiency；
Precision drill simultaneously after is high, is effectively guaranteed product quality；Using modular combining structure, the low cost of frock, it is easy to
Realize and promote；Mandrel uses detachable connection fixed form, can have certain versatility, facilitates enterprise to carry out frock
Management, and reduce the cost of enterprise's fabricating tools.
Brief description of the drawings

Fig. 2 is internal structure schematic diagram of the present utility model；
Fig. 3 is that Fig. 1 removes the structural representation after 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 drilling tool, including drill jig sleeve 1, mandrel 2, pressing plate 3, hold-down bolt
4, in the processing district that is centrally formed of the drill jig sleeve 1, the branch for being supported to workpiece slope is provided with the processing district
Step 5 is supportted, the drill jig sleeve 1 is additionally provided with for carrying out spacing position limiting structure 6 to side surface of workpiece, can at the center of processing district
Dismantling connection has the mandrel 2, and the screw that can be engaged with hold-down bolt 4, the spiral shell are offered in the free end of the mandrel 2
Center line arrangement of the hole along the mandrel 2, is held by the pressing plate 3, hold-down bolt 4 to the workpiece being located on mandrel 2
Face pressure is tight, and positioning hole 7 is further opened with the side of the drill jig sleeve 1, and the positioning hole 7 also inwardly runs through the mandrel 2.
As shown in Figures 1 and 2, the drill jig sleeve 1 includes generally U-shaped intermediate 1a, in intermediate 1a both sides
