Abstract
The utility model provides a drilling tool. The drilling tool comprises a drill jig body, wherein the drill jig body is provided with a workpiece hole which is used for placing a rod portion of a pin shaft. The drill jig body is further provided with more than one die hole, and each die hole is communicated with the workpiece hole. A supporting base used for fixing the drill jig body which is installed into the pin shaft is further provided, and the supporting base is provided with at least one base, a front base wall and a back base wall. The front base wall is provided with a screw hole which is matched with a locking bolt. A die with the drilling tool is applied to machining of an anti-falling through hole in the position of a center line on the rod portion of the pin shaft, is high in efficiency, and solves the problem that dimensional precision and form and position tolerance processed by adopting other machining methods on common conditions are difficult to ensure. The drilling tool is accurate in location, simple and convenient to operate, and good in safety performance. The die holes required are drilled in the length direction of the drill jig body according to different lengths of the pin shaft so that the drilling tool turns into a multi-station drilling device.
Description
Technical field
The utility model relates to a kind of drilling tool, and cooperation is holed to add to the slip-off preventing through hole of the bar portion position of center line of bearing pin and used man-hour.
Background technology
Bearing pin has received in Aeronautics and Astronautics, defence field widely and having used owing to possess good location and slip-off preventing effect.Its relevant criterion all has special requirement to accurate positioning, slip-off preventing, the dimensional uniformity of bearing pin.This just requires the position dimension in the slip-off preventing hole of bearing pin bar portion, form and position tolerance all must be controlled within certain scope.So the processing method in this slip-off preventing hole is particularly important.Because the slip-off preventing hole after the processing is in the position of bar portion, adopt Milling Process efficient too low, product cost is high, has bigger mismachining tolerance, adopts conventional boring, and the uniformity of position, slip-off preventing hole size also can't guarantee.Solve that above efficient is low, the problem of dimensional instability, the processing of bearing pin and measure and to possess following six characteristics: 1, simple and easy to operate.2, has versatility.3, accurate positioning.4, certainty of measurement is high.5, efficient is high.6, security is good.
Summary of the invention
The problem that the utility model will solve provides a kind of drilling tool, can be fast, accurately to the processing of holing of the slip-off preventing through hole of the bar portion position of center line of bearing pin, and guarantee dimensional accuracy, stability and the uniformity in the hole that drills through.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: a kind of drilling tool, comprise model drilling body, and have the workpiece hole of putting into the pin axle portion on the model drilling body; Also have at least more than one nib on the model drilling body, said each nib all connects with workpiece hole.
Further, be to strengthen the stability of frock, this frock also be provided with one be used for fixing the model drilling body of the bearing pin of packing into supporting base, said supporting base has a base and forward and backward seat wall at least, has a screw on the front stall wall, screw matees a clamping screw.
Further, the axial line of the axial line of said nib and workpiece hole intersects vertically.
Further, said screw keeps concentric with the workpiece hole that is placed on the model drilling body in the supporting base.
Further, said nib is a through hole.Like this, the expense bits after each boring can be cleared out of model drilling body smoothly, can not exert an influence to process, and can get into the processing to next bearing pin fast.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, these cover moulds of industrial equipment can be processed on common driller, and processing method is easy and simple to handle; Efficient is high; Security is good, and the product processed dimensional accuracy is high, and form and position tolerance can meet design requirement.Measuring easyly, use slide measure and micrometer just can accomplish measurement, is the major tuneup that the processing method of routine is carried out.

The specific embodiment
As shown in Figure 1, the utility model needs pin axle portion position of center line is carried out the processing in slip-off preventing hole.Fig. 2 has provided the structure cross-sectional schematic of the model drilling body of putting into bearing pin, has the workpiece hole of putting into the pin axle portion on the model drilling body, also has at least more than one nib on the model drilling body, and said each nib all connects with workpiece hole.Present embodiment is that example describes with the embodiment with a nib only.The bar portion of bearing pin is packed in the model drilling body, and the bearing pin cap is stuck in the workpiece hole opening part, and the nib position is exactly the required position that gets out the slip-off preventing hole of pin axle portion, and drill bit stretches in the nib, nib spacing down, can get out the slip-off preventing hole comparatively accurately.
Model drilling body and bearing pin can not produce offset in boring procedure in order further to avoid; Strengthen the stability of frock; This frock also be provided with one be used for fixing the model drilling body of the bearing pin of packing into supporting base; Said supporting base has a base and forward and backward seat wall at least, has a screw on the front stall wall, and screw matees a clamping screw.Unclamp the clamping screw of drilling tool, bearing pin is packed in the model drilling body, together be placed in the supporting base then the model drilling body that bearing pin is housed; Tighten clamping screw, can hole, after boring finishes; Unclamp clamping screw, take out bearing pin (workpiece), promptly accomplish processing.
Need intersect vertically with pin axle portion axial line when the slip-off preventing hole, and then the axial line of the axial line of said nib and workpiece hole need intersect vertically.
For the shank of bolt head of guaranteeing clamping screw can better push against bearing pin, said screw should keep concentric with the workpiece hole that is placed on the model drilling body in the supporting base.
For making the expense bits after each boring can clear out of model drilling body smoothly, can not exert an influence, and can get into processing fast next bearing pin to process, said nib should be through hole.
Simultaneously, the different length according to bearing pin on the length direction of model drilling body gets out the hole that needs, and promptly model drilling body is provided with a plurality of nibs, therefore is referred to as the multistation drilling equipment.
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
