Abstract
The utility model discloses a sheet metal drilling frock, including the block, open the recess that has peripheral profile and work piece to suit on the block, the position in the corresponding work piece hole in bottom of recess is equipped with the boss that supports the work piece, the boss upper surface is opened has the blind hole that is greater than the work piece hole with the coaxial and diameter in work piece hole. The sheet metal work piece supports in as for the recess and by the boss owing to have the blind hole on the boss, the blind hole gets into after the drill bit hole on the work piece and in, can not lead to the fact the damage to the block, the boss is strong to sheet metal supporting role simultaneously, the drilling position precision height.
Description
Technical field
The utility model relates to a kind of frock, particularly a kind of sheet drill hole tool.
Background technology
Thin plate (0.2 ~ 4mm) is due to thinner thickness, and thin plate not easily clamps, and when holing, thin plate easily produces the defects such as distortion, cause product quality to go wrong, and bore position precision is poor.
Utility model content
In view of this, the technical problems to be solved in the utility model is to provide a kind of sheet drill hole tool, effectively supports, bore position precision is high to thin plate.
Sheet drill hole tool of the present utility model, comprise block, described block has the groove that peripheral profile and workpiece adapt, the position of the corresponding workpiece hole in bottom of described groove is provided with the boss supporting workpiece, and described boss upper surface has the blind hole that and diameter coaxial with workpiece hole is greater than workpiece hole.
Further, described block has the bleed-off passage that bottom portion of groove is led in one end, the other end is connected with evacuator.
Further, described bottom portion of groove is circumferentially with support ring for supporting workpiece along workpiece.
The beneficial effects of the utility model: sheet drill hole tool of the present utility model, comprise block, described block has the groove that peripheral profile and workpiece adapt, the position of the corresponding workpiece hole in the bottom of described groove is provided with the boss supporting workpiece, and described boss upper surface has the blind hole that and diameter coaxial with workpiece hole is greater than workpiece hole.Sheet workpiece is as being supported by boss in groove, and due to boss having blind hole, drill bit enters in blind hole after holing on workpiece, can not cause damage to block, and boss is strong to thin plate supporting role simultaneously, and bore position precision is high.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further described:
Fig. 1 is that the axle that waits of the present utility model measures intention;
Fig. 2 is that axle such as grade of the present utility model survey partly cuts open schematic diagram.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model is described in detail, as shown in the figure: the sheet drill hole tool of the present embodiment, comprise block 1, described block has the groove 2 that peripheral profile and workpiece adapt, the position of the corresponding workpiece hole in bottom of described groove 2 is provided with the boss 3 supporting workpiece, sheet workpiece is placed on boss 3 by groove 2, the quantity of boss 3 is identical with the quantity in hole on thin plate, namely on workpiece the below in each hole all to there being a boss, described boss 3 upper surface has the blind hole 4 that and diameter coaxial with workpiece hole is greater than workpiece hole, supported by boss 3 pairs of workpiece, and Support Position is the bore position of workpiece, support effect is good, drill bit enters after holing on workpiece in blind hole 4, damage can not be caused to block 1.
As the further improvement of technique scheme, described block 1 has bleed-off passage 5, bleed-off passage 5 one end is the end 51 of bleeding led to bottom groove 2, the other end is the link 52 be connected with evacuator,, workpiece bottom interior to groove 2 by evacuator vacuumizes, make workpiece be subject to negative pressure and more firm be placed on boss 3, during to Workpiece boring, workpiece not easily produces distortion and position sideslip.
As the further improvement of technique scheme, the support ring 6 for supporting workpiece is circumferentially with along workpiece bottom described groove 2, support ring 6 is except supporting workpiece edge, can also be undertaken airtight by the space that vacuumizes below workpiece, namely the upper and lower edge of support ring 6 forms ring shaped contact with workpiece and groove floor respectively, and the end 51 of bleeding of bleed-off passage 5 is positioned at the inside of support ring 6, when vacuumizing like this, vacuum tightness is good, there will not be gas leakage, more firm under workpiece suction function.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
