Abstract
The utility model provides a drill hole of a T-shaped bolt. The drill hole of the T-shaped bolt comprises a drill jig body. The drill jig body is provided with a screw rod hole for placing of a T-shaped bolt rod portion and a screw head hole for placing of a bolt head portion. The screw rod hole and the screw head hole are communicated with each other to form a workpiece hole of the drill jig body. The drill jig body is further provided with a die hole which is communicated with the screw rod hole. The drill jig body can also be provided with a supporting seat used for fixing the drill jig body where the T-shaped bolt is arranged. The supporting seat is at least provided with a base seat, a front seat wall and a back seat wall, wherein the front seat wall is provided with a screw hole which is matched with a locking bolt. The drill hole of the T-shaped bolt can be applied to machining of anti-dropping through holes on the center line of the T-shaped bolt rod portion, efficiency is very high, the problem that size precision and geometric tolerance are difficult to guarantee when other machining methods are adopted on a common situation is resolved, positioning is precise, operation is simple and convenient, and safety is good.
Description
Technical field
The utility model relates to a kind of drilling tool of T type bolt, and cooperation is holed to add to the slip-off preventing through hole of the bar portion position of center line of T type bolt and used man-hour.
Background technology
T type bolt 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 T type bolt.This just requires the position dimension in the slip-off preventing hole of T type bolt shank, 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 can't guarantee.Solve that above efficient is low, the problem of dimensional instability, the processing of T type bolt 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 of T type bolt; 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 T type bolt, 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 of T type bolt; Comprise model drilling body, have the screw hole of putting into T type bolt shank and the spiral shell head hole of putting into bolt head on the model drilling body, screw hole and spiral shell head hole connect the common workpiece hole of forming model drilling body each other; Also have nib on the model drilling body, said nib and screw hole connect.
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 T type bolt 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 scrap 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 T type bolt 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 T type bolt shank position of center line is carried out the processing in slip-off preventing hole.Fig. 2 has provided the structural representation of model drilling body; Have the screw hole of putting into T type bolt shank and the spiral shell head hole of putting into bolt head on the model drilling body; Screw hole and spiral shell head hole connect the common workpiece hole of forming model drilling body each other, also have nib on the model drilling body, and said nib and screw hole connect.Present embodiment is that example describes with the embodiment with a nib only.The bar portion of T type bolt is packed in the screw hole of model drilling body; The spiral shell head position of T type bolt is stuck in the spiral shell head hole of model drilling body; Each workpiece slip-off preventing hole of getting is consistent with respect to the position of whole T type bolt like this, and the nib position is exactly the required position that gets out the slip-off preventing hole of T type bolt shank, and drill bit stretches in the nib; Nib spacing down, can get out the slip-off preventing hole comparatively accurately.
For further avoiding model drilling body and T type bolt generation offset in boring procedure; Strengthen the stability of frock; This frock also be provided with one be used for fixing the model drilling body of the T type bolt 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, T type bolt is packed in the model drilling body, together be placed in the supporting base then the model drilling body that T type bolt is housed; Tighten clamping screw, can hole, after boring finishes; Unclamp clamping screw, take out T type bolt (workpiece), promptly accomplish processing.
Need intersect vertically with T type bolt shank 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 T type bolt, said screw should keep concentric with the workpiece hole that is placed on the model drilling body in the supporting base.
For making the scrap after each boring can clear out of model drilling body smoothly, can not exert an influence, and can get into processing fast next T type bolt to process, said nib should be through hole.
Simultaneously, the different length according to T type bolt 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.
