At device resource limited or in order to save frock manufacturing cost time, simultaneously also in order to improve working (machining) efficiency, technique can be improved, change rig into machining center by common driller, this just needs to make specific frock to realize the processing that clamped one time positioning instant can complete shoulder hole.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, accurate positioning, easy to operate shaped piece drilling tool, can increase work efficiency, reduce frock cost.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of shaped piece drilling tool, comprise bent plate, positioning core axle, alignment pin and retaining mechanism, described bent plate comprises vertical component effect in 90 ° and horizontal part, described positioning core axle is vertically set on bent plate horizontal part, described alignment pin is vertically set on the vertical component effect of bent plate, and described retaining mechanism coordinates with positioning core axle top.
Preferably, described bent plate is Split type structure, and described vertical component effect and horizontal part are located by pin and bolt pair and fixed, and described horizontal part is provided with pin-and-hole, and described alignment pin is arranged in pin-and-hole.
Preferably, described retaining mechanism comprises pressing plate and locking nut, and described positioning core axle top is provided with external screw thread, and described locking nut coordinates with positioning core axle screw top.
Preferably, the pin-and-hole on described horizontal part and alignment pin are two.
Preferably, the horizontal part of described bent plate is middle is provided with groove.
The beneficial effect adopting technique scheme to produce is: positioning core axle and alignment pin are matched with the centre bore on workpiece and both sides unthreaded hole respectively, realize the location of workpiece in vertical and horizontal both direction, workpiece is fixed by recycling pressing plate and locking nut; Then by the horizontal part of bent plate upward, by levelling for the lower plane of workpiece center hole surrounding cushion block and B place shoulder hole, machining center for coordinate reference points, carries out shoulder hole middle through-hole and the processing of upper end counterbore with positioning core axle center line; Completion of processing, then placed on the table by the horizontal part of bent plate, supports the counterbore place of shoulder hole with suitable cushion block, also with positioning core axle center line for coordinate reference points, carry out the processing in shoulder hole lower step hole.The utility model has that structure is simple, accurate positioning, easy to operate advantage, cost of manufacture is cheap simultaneously, can realize the processing that clamped one time completes shoulder hole, improve working (machining) efficiency, ensure that product quality.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of shaped piece drilling tool as shown in Fig. 5,6,7, comprise bent plate 1, positioning core axle 2, alignment pin 3 and retaining mechanism 4, described bent plate 1 comprises vertical component effect 11 in 90 ° and horizontal part 12, described positioning core axle 2 is vertically set on the horizontal part 12 of bent plate 1, described alignment pin 3 is vertically set on the vertical component effect 11 of bent plate 1, and described retaining mechanism 4 coordinates with positioning core axle 2 top.
As a kind of preferred structure, described bent plate 1 is Split type structure, and described vertical component effect 11 and horizontal part 12 are located by pin 13 and bolt pair 14 and fixed, and described horizontal part 12 is provided with pin-and-hole, and described alignment pin 3 is arranged in pin-and-hole.The bent plate 1 of Split type structure is convenient to dismounting maintenance, makes the form and position tolerance of vertical component effect 11 and horizontal part 12 meet work pieces process requirement.
Wherein, described retaining mechanism 4 comprises pressing plate 5 and locking nut 6, and described positioning core axle 2 top is provided with external screw thread, and described locking nut 6 coordinates with positioning core axle 2 screw top.
In order to ensure accurate work piece positioning, the pin-and-hole on described horizontal part 12 and alignment pin 3 are two, and two alignment pins 3 are coordinated with the unthreaded hole of two on workpiece 17 10 respectively; Simultaneously in order to reduce volume, make the utility model more compact structure, be provided with groove 15 in the middle of the horizontal part 12 of described bent plate 1, groove 15 can hold the boss 16 on workpiece 17 top.
