Description
Technical field
The utility model relates to little axial workpiece radial bore manufacture field, particularly a kind of drill jig for little shaft parts drill hole.
Background technology
Little axial workpiece is part type common in aerial sight product, as shown in the little axle design of part schematic diagram of Fig. 1, when its radial bore, hole and axes normal are the keys of processing parts, and secondly convenient mounting and clamping is also fast ensure part production cycle essential condition.
At present, self-control axle is clamped on boring machine or milling machine by conventional processing method, part is arranged in self-control axle and centers with centre drill, then bit bore is changed, this kind of processing method by self-control axle making and installation error, boring time the drill bit factor such as to tremble affect and be difficult to ensure hole and axes normal technical requirement, in processing, more bit change also makes working (machining) efficiency low, device therefor is also high precision apparatus, so cause part crudy unstable, production efficiency is low, production cost is high, have impact on part crudy and part supporting cycle.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of current processing method in reliability and convenience, a kind of drill jig for little shaft parts drill hole is provided, use this drill jig processing parts can ensure the technical requirement of part reliable and stable, quickly and easily, the uniformity realizing crudy controls, and improves working (machining) efficiency.
The technical scheme that the utility model solves the employing of its technical problem is, for the drill jig of little shaft parts drill hole, which comprises at least body and drill bushing, it is characterized in that: further comprising pressing plate, body is made up of two crossbeams at longeron and the upper and lower two ends of longeron homonymy, wherein entablature vertically has through hole, drill bushing is by the entablature interference fits of upper through hole and body, longeron level has locating hole, internal diameter size and the little axle part outside dimension of locating hole match, locating hole is in same plane with the axis of upper through hole and mutually vertical, sill end is rotatably connected to pressing plate by bearing pin.
Described pressing plate central shaft rotates the face that formed and locating hole, the axis of upper through hole is also all in same plane.
There is hemisphere jut the position that described pressing plate upper end contacts with little axle part afterbody.
The beneficial effects of the utility model are that the drill jig of this little axial workpiece radial bore makes simply, easy to use, make on its tail end face being pressed on little axle part by rotating pressing plate, hand-held compression is reliable, reach spacing, anti-rotation, pressuring action, little axle part is accurately located and fast easy to loading and unloading, working (machining) efficiency is high, and dimensional accuracy and the Geometrical Tolerance Principle of little axle part can be ensured, when processing small shaft part in enormous quantities, its advantage is particularly remarkable.Body and drill bushing are interference fits, thus Long-Time Service cause drill bushing wear and tear after, replaceable drill bushing, to ensure little axle part processing precision.

In figure: 1, body; 2, drill bushing; 3, pressing plate; 4, bearing pin; 5, little axle part; 6, longeron; 7, entablature; 8, sill; 9, upper through hole; 10, locating hole; 11, hemisphere jut.
Detailed description of the invention
Embodiment 1
Shown in this Drilling Jig Structure schematic diagram for little shaft parts drill hole of the utility model as Fig. 2, which comprises at least body 1 and drill bushing 2, it also comprises pressing plate 3, body 1 is made up of two crossbeams at longeron 6 and the upper and lower two ends of longeron 6 homonymy, wherein entablature 7 vertically has through hole 9, drill bushing 2 is by entablature 7 interference fits of upper through hole 9 with body 1, longeron 6 level has locating hole 10, internal diameter size and little axle part 5 outside dimension of locating hole 10 match, locating hole 10 is in same plane with the axis of upper through hole 9 and mutually vertical, sill 8 end is rotatably connected to pressing plate 3 by bearing pin 4.
Pressing plate 3 central shaft rotates the face that formed and locating hole 10, the axis of upper through hole 9 is also all in same plane.
The process of little axle part 5 radial hole is as follows: be placed on Drilling machines bench face by the bottom surface level of sill 8, rotary pressure plate 3 to horizontal level, little axle part 5 end is put into the locating hole 10 of body 1 longeron 6, and the end face in the middle part of little axle part 5 is close to longeron 6, adjustment drill bushing 2 is pressed close to little axle part 5 surface, be adjusted to and stay 1mm gap, after little axle part 5 installs, with bearing pin 4 for rotating shaft rotates up pressing plate 3, pressing plate 3 upper end contacts with the afterbody of little axle part 5, by pressing plate 3, little axle part 5 is fixed, manual thrust is moderate, hand-held to drill bit, drill bit carries out Drilling operation by drill bushing 2 to little axle part 5, after machining, unclamp pressing plate 3, pressing plate 3 rotates to horizontal level around bearing pin 4, take off the little axle part 5 processed, the hole of little axle part 5 and position dimension are all processed and are put in place, carry out the processing of next little axle part 5.
The drill jig of this little axial workpiece radial bore makes simple, easy to use, make on its tail end face being pressed on little axle part 5 by rotating pressing plate 3, hand-held compression is reliable, reach spacing, anti-rotation, pressuring action, make little axle part 5 accurately location and fast easy to loading and unloading, working (machining) efficiency is high, and dimensional accuracy and the Geometrical Tolerance Principle of little axle part 5 can be ensured, when processing small shaft part 5 in enormous quantities, its advantage is particularly remarkable.Body 1 and drill bushing 2 be interference fits, therefore after Long-Time Service causes drill bushing 2 wearing and tearing, replaceable drill bushing 2, to ensure little axle part 5 machining accuracy.
Embodiment 2
There is hemisphere jut 11 position that pressing plate 3 upper end of the present embodiment contacts with little axle part 5 afterbody, when pressing plate 3 rotatably compresses little axle part 5, the hemisphere jut 11 of pressing plate 3, just to the hollow space of little axle part 5 afterbody body, makes pressing plate 3 better can compress little axle part 5, prevents its axial rotation.
Little axle part 5 is placed in by end in the locating hole 11 that mates with it, and middle part is close to inside longeron 6, and afterbody is compressed by pressing plate 3, achieves omnibearing location, guarantees that each axis of its X, Y, Z can not produce mobile or rotate, ensure that machining accuracy.
